The LEVEL of TECHNOLOGY

I. the technical Field to which the invention relates

[0002] the Present invention generally relates to communications and more specifically to techniques for supporting emergency calls and location.

II. The level of technology

[0003] wireless communication Networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, etc., These wireless networks may be multiple access networks, has a capability to support multiple users by sharing the available network resources. Examples of such networks multiple access include: network Multiple Access Code Division (CDMA); network Set the public Access with time Division (TDMA); network Multiple Access Frequency Division (FDMA)network, an Orthogonal FDMA (OFDMA) and FDMA network with Single-Carrier (SC-FDMA).

[0004] wireless communications Network can support communication for a certain number of mobile stations. The mobile station may send an emergency call in response to an emergency event. An emergency call is a call to emergency services (e.g. police, fire, medical or other emergency services) and can also be referred to as calling the emergency services, E911, etc. Emergency call may be initiated by a user are well known non emergency communication, such as '911' in North America or '112' in Europe. It is desirable to efficiently route an emergency call to the appropriate emergency operations centre that can handle the call. It may also be desirable to provide the emergency operations centre the location of the mobile station.

A BRIEF DESCRIPTION of the INVENTION

[0005] herein is described a method of routing an emergency call originating from a mobile station via a Femto access point (FAP) in a wireless communication network, and determining the location of a mobile station. In the aspect, an emergency call from a mobile station may be routed to the appropriate emergency communication center based on the information location to FAP. To understand who their "location" and "position" are synonymous and are often used interchangeably. In one implementation, the information of location for FAP may contain the ID of the macro cell to the macro cell, which is intense, the received signal in FAP, or having to FAP overlapping coverage. Information location for FAP can optionally contain the ID of the Switching Center Mobile communications (MSC) macrosty, which can be determined based on the ID of the macro cell. ID of the macro cell and/or ID MSC macrosty can be assigned to the FAP (e.g., during initialization FAP) and can be used to access the database. The database can store the routing information for emergency communication centers depending on the ID cell ID and MSC. In another implementation, the information of location for FAP may include an evaluation of location for FAP. Assessment of the location can be used to access the geographic database that can store the routing information for emergency communication for different geographical areas.

[0006] In one implementation, the mobile station may send FAP first message in order to make an outgoing emergency call. FAP can send the object network a second message to initiate an emergency call. Just FAP can send to the network object in the location information for the FAP to use when selecting emergency operations centre emergency is on call. An emergency call can be connected to the emergency communication center based on the information location to FAP. Then the mobile station can communicate with the center for emergency communication to an emergency call.

DETAILED DESCRIPTION

[0015] the methods Described here can be implemented for various wireless networks such as wireless wide area network (WWAN), wireless local area network (WLAN), wireless personal area network (WPAN), and so the concept of "network and "system" are often used interchangeably. A WWAN may be a network of Multiple Access Code Division (CDMA)network Multiple Access with time Division (TDMA), a network of Multiple Access Frequency Division (OFDMA), a network of Multiple Access Orthogonal Frequency Division (OFDMA), a network of Multiple Access Frequency Division and Single-Carrier (SC-FDMA)network Long-term Development (LTE) and so on CDMA Network may implement one or more radio access technologies (RATS)such as cdma2000, Wideband-CDMA (W-CDMA), etc. cdma2000 includes standards IS-95, IS-2000 and is-856. A TDMA network may implement a Global System Mobile (GSM)Communication System, Digital Mobile Phone service (D-AMPS) or other RAT. GSM and W-CDMA are described in documents from a consortium named "Partnership Project Third Generation (3GPP). cdma2000 is described in documents from a consortium named "the Second Project Third Generation Partnership" (3GPP2). Documents 3GPP and 3GPP2 is publicly available. The WLAN network may be a network standard IEEE 802.11x, and network WPAN may be a Bluetooth network, an IEEE 802.15x or some other type of network. The techniques also can be implemented for any combination of networks WWAN, WLAN and/or WPAN. For clarity, certain aspects of the techniques described below for 3GPP2 networks.

[0016] Figure 1 shows a sample deployment of a network that includes a wireless network 100, and third-party network 102. Wi-Fi is I network 100 includes a network 104 radio access and other network objects, to support various services. The network 104 may implement a radio access CDMA 1X, high-Speed Packet Data (HRPD) or other radio access technologies. The network 104 radio access may include a certain number of base stations and a certain number of Femto access point (FAP), which can communicate wirelessly to a certain number of mobile stations. For simplicity, figure 1 shows only one FAP 120, only one base station 124 and only one mobile station 110. The base station is the base station that provides the coverage area of the communication for a relatively large area (for example, a radius of several hundred meters to several kilometers) and can provide unlimited access for mobile stations that have subscribed to the service. FAP is a station that provides coverage communication for relatively small areas (e.g., house, apartment, part of a large building, and so on), and can provide limited access for mobile stations that are associated with FAP (e.g., mobile stations for users in the house). The base station and/or its coverage area may be referred to as a macro cell. FAP and/or its coverage area may be referred to as a Femto cell. FAP can also be referred to as a home or Femto base camp of the Oia, home or Femto Node B, a home or Femto selected Node B (eNB), etc.

[0017] the base station 124 may communicate with the Controller 126 of Base Stations (BSC), which can additionally communicate with the MSC 132. MSC 132 may perform a switching function for call switching lines, and can route messages Short Message Service (SMS). FAP 120 may communicate with the Femto gateway 122 security, which can provide security (e.g., the remaining part of the network) access through FAP. Femto gateway 122 security can additionally communicate with the tool Management Functions Call Session (CSCF), which can provide services and session management for access via FAP and can maintain session state for support services Multimedia Subsystem (IMS) based on Internet Protocol (IP), such as Voice over IP (VoIP), etc. CSCF 128 can communicate with the Function 130 Internetworking Femtocell (MFIF) Parts of Mobile Applications (MAP), which can support some of the functionality of MSC on access through the FAP and provide the MAP interface ANSI-41 from the FAP to the remaining part of the network. MFIF 130 may also be referred to as the Femto Convergence Server (FCS). The center 134 of the Operation, Administration, maintenance and Support (OAM&P) can perform the hypoxia functions to support the functioning of the wireless network 100. Center 134 OAM&P can communicate with the MFIF 130, MSC 132 and other network entities (not shown in figure 1 for simplicity).

[0018] the Center 140 of the Mobile Positioning (MPC) can perform various functions for accommodation services and can support a user's privacy, authorization, authentication, roaming support, pricing/billing and accounting, service management, calculation, etc. MPC 140 may have access to the Database 142 Routing Data at the Coordinates (CRDB), which can store a reference table that relates the MSC ID and cell ID and/or geographic location to the Point of Response to the challenges of Public Safety/emergency communication Centers (PSAP/EC). The object 150 Position (PDE) may support positioning for mobile stations. Positioning refers to the process measurement/calculation of the estimate of the location of the target device. Assessment of the location can also be referred to as the evaluation of the position, positioning, fixing, etc. PDE 150 may have access to the Almanac of Base Stations 152(BSA), which can store information (e.g., geographic coordinates, coverage, power transmission characteristics of the antenna and so on) for sites and base stations in a wireless network. Information from BSA 152 may be used to assist in positioning mobile is Tanzi.

[0019] the Gateway Environment/Management Gateway Medium (MGW/MGCF) 158 may support conversion between: (i) the Session Initiation Protocol (SIP/IP and Alarm Call, such as SS7 to the public Switched Telephone Network (PSTN), and (ii) packetized voice transmission (e.g., transported using IETF RTP) and voice-switched lines (for example, transported using ANSI T1 or CEPT E1). MGW/MGCF 158 can be used whenever you want to make a VoIP call (e.g., FAP 120) passed to the PSTN user (e.g., PSAP 170). For routing calls between MGW/MGCF 158 and PSAP 170 can be selected router 160. PSAP 170 may be responsible for answering emergency calls and can be managed or owned by a government organization, such as a country or city.

[0020] Figure 1 shows some of the network features that can be represented in the wireless network 100. Wireless network 100 may include network objects that support calls with packet switching, calls circuit-switched lines, services, location, etc. of the Wireless network 100 can also implement the Protocol of the mobile transmission network ANSI-41, which supports the identification and authentication of users and call routing to enable roaming and advanced services. ANSI-41, as PR is usually used for 3GPP2 networks, whereas the MAP, usually used for 3GPP networks.

[0021] the Mobile station 110 (MS) can be one of the many mobile stations supported by the wireless network 100. Mobile station 110 may be stationary or mobile and may also be referred to as user equipment (UE), terminal, access terminal, a subscriber module, station, etc. Mobile station 110 may be a cellular phone, a personal digital assistant (PDA), wireless device, wireless modem, a portable computer, a telemetry device, a tracking device, etc. Mobile station 110 may be able to communicate with FAP or base station at any given time in order to obtain communication services.

[0022] the Mobile station 110 and/or FAP 120 may receive signals from one or more satellites 190, which may be parts of: a Global Positioning System (GPS) of the United States, the European system Galileo (Galileo), the Russian GLONASS system, or some other Satellite Positioning System (SPS). Mobile station 110 and/or FAP 120 may measure the signal from the satellites 190 and get to satellites pseudorange measurement. As the mobile station 110 and/or FAP 120 may measure signals from base stations in the network 104 radio access and get to the basic who's measuring stations timing and/or measuring the intensity of the signal. Measuring the pseudorange measurement timing and/or measuring the intensity of the signal can be used to obtain an estimate of the location for the mobile station 110 or FAP 120. As the mobile station 110 and FAP 120 may support one or more ways of positioning, such as GPS, GPS with support (A-GPS), Enhanced triangulation with measured lengths in a Straight Line (AFLT), etc.

[0023] the Mobile station 110 may communicate with the base station 124 and initiates an emergency call. ID of a serving cell may be provided MPC 140 during call setup. MPC 140 may access CRDB 142 by using an ID of a serving cell to determine the routing information for the PSAP (e.g., PSAP 170), which can take an emergency call from the mobile station 110. Routing information may include: (i) Code Routing of Emergency services (ESRD), which is not dialed reference number used for identification and routing to PSAP 170; (ii) Key Routing of Emergency services, which is not dialed reference number used for identification and routing to PSAP 170, and also to identify the emergency call; or (iii) some other information. Each PSAP may be associated with one ESRD, as well as with the pool ESRK. During an emergency call, the mobile camp is AI 110 can be assigned to one ESRK from the pool. Then an emergency call can be routed to PSAP 170 based on the ESRK or ESRD.

[0024] CRDB 142 and BSA 152 can be supplied ID, ID MSC and locations of base stations in the wireless system 100. This information can be used to determine the appropriate PSAP for emergency call from a mobile station that communicates with the base station. For example, CRDB 142 may provide for ESRK PSAP based on the ID serving cell ID and MSC to the serving cell. However, CRDB 142 and BSA 152 may not be supplied ID, ID MSC and locations FAP, because this information is usually not known before FAP was deployed, and therefore may take a long time and be expensive to ensure. Accordingly, CRDB 142 and BSA 152 may not be able to provide the routing information to the PSAP for emergency calls originating from mobile stations performing communication with FAP.

[0025] In an aspect, routing emergency calls for mobile stations performing communication with the FAP can be maintained on the basis of the information of the location for FAP. Information location for FAP can contain any information identified based on the location of the FAP, and used to ensure that the FAP operates in the permitted well-spectrum. Information location for FAP can be determi is Elena on the basis of the location of the FAP in accordance with the as is described below.

[0026] MFIF 130 may be assigned a unique ID MSC (or some unique ID MSC) to support interaction on ANSI-41. ID MSC assigned to MFIF 130 may be referred to as MSC ID MFIF, ID 1 MSC etc. FAP 120 may perform the initialization after power-up and can be assigned an ID of a serving cell after successful authentication and authorization. This ID serving cell may be referred to as ID Femto cell ID 1 serving cell, etc. ID Femto cell may be associated with the MSC ID MFIF and can be used for radio access. ID Femto cell ID and MSC MFIF may not be available in CRDB 142 or BSA 152.

[0027] the Location of FAP 120 (i.e. the location of femtocells can be used for routing an emergency call from FAP 120. The following describes several exemplary schemes for routing an emergency call based on the location femtocells.

[0028] In the first scheme for routing an emergency call based on the location femtocells, FAP 120 may be assigned additional ID of a serving cell and an additional ID MSC, for example, during initialization. Optional ID of a serving cell may be referred to as the ID of the macro cell ID 2 serving cell, etc. Additional ID MSC may be referred to as MSC ID macrosty, ID 2 MSC etc. ID of the macro cell ID and MSC macrosty can be obtained based on the location FAP 20. In one implementation, the ID of the macro cell may be a cell ID for: macro cell with the closest to FAP 120 antenna; macro cell with the most intense signal or an intense signal for FAP 120; macro cell, which is overlapping with the FAP 120 coverage; etc. ID MSC macrosty can be ID MSC in the MSC that serves this macro cell. ID of the macro cell ID and MSC macrosty, respectively, can be for an existing macro cell and the existing MSC, respectively, and can be reused for FAP 120 for routing emergency calls. In another version, FAP 120 may be created ID of the macro cell ID and MSC macrosty, and they may not correspond to actual sauté or actual MSC. For example, the FAP may be located outside the zone of normal network coverage, and to cover this extended zone, which can be deployed FAP, can be created additional ID serving cell ID and MSC. Optional ID of a serving cell and an additional ID MSC can also be done within the normal coverage area, in order to avoid problems, when the real ID cell are changed or deleted, as this may affect FAP assigned to real ID cell. Optional ID of a serving cell and an additional MSC ID will not match the physical base stations, but can be used to support m is scrutinize emergency calls from FAP. For all versions, appointed by the FAP ID MSC macrosty and ID of the macro cell can be provided in CRDB 142 and/or BSA 152. ID of the macro cell ID and MSC macrosty assigned to the FAP 120 may be used when selecting the appropriate PSAP for emergency calls using the existing ANSI procedure J-STD-036B.

[0029] Figure 2 shows the execution flow 200 call for routing an emergency call from FAP, using the ID of the macro cell ID and MSC macrosty. Source, mobile station 110 may make an outgoing emergency call (e.g., E911) using FAP 120 and may provide the ID of the mobile station (MSID) (stagea). MSID may contain an Electronic Serial Number (ESN), international Mobile Subscriber identity (IMSI), Mobile Equipment Identifier (MEID), a Mobile Identification Number (MIN) and/or some other identity. FAP 120 may receive an emergency call and can send MFIF 130 (e.g., SIP INVITE (Invitation SIP)request emergency call (e.g., E911) (stageb). The E911 call request may include the MSID of the mobile station 110, ID MSC macrosty and ID of the macro cell, assigned to the FAP 120, etc. MFIF 130 may take from FAP 120 request E911 call and, in response, may send in MPC 140 Request message to the implementation of an outgoing call (ORREQ) using ANSI-41 (stepc). The ORREQ message may include the MSID, ID MSC macrosty and ID of the macro cell, p is inate on stage b.

[0030] MPC 140 may take the ORREQ message and can search for combinations of ID MSC macrosty and ID of the macro cell in CRDB 142, and may find PSAP (e.g., PSAP 170) and ESRK or ESRD associated with the PSAP. PSAP 170 may be appropriate for the location of FAP 120 (and therefore the location of the mobile station 110), because the ID of the MSC macrosty and ID of the macro cell were originally assigned to the FAP 120 based on the location femtocells. Then MPC 140 may return MFIF 130 the Response message implementation outgoing call (orreq), which may include ESRK or ESRD (staged). Then MFIF 130 may forward the PSAP 170 emergency call on the basis of ESRD or ESRK, and may include Mobile Reference Number (MDN) of the mobile station 110 (stepe). Forwarding can occur through selective router 160, via MGW/MGCF 158 and selective router 160, through CSCF 128, MGW/MGCF 158, and selective router 160 or via other network objects.

[0031] MPC 140 may search for the characteristics of the positioning of the mobile station 110, based on enacted on the stage ofc, MSID. MPC 140 may on stagebto take from the FAP 120 characteristics of positioning the mobile station 110, if the mobile station 110 has sent the data at the stage ofa. Then MPC 140 may send PDE 150 Request message to the Geographic Position (GPOSREQ)on the part of the characteristics of positioning (MPCAP) and MSID mobile station 110, ID MSC macrosty and ID of the macro cell to FAP 120, etc. (stagef). Then PDE 150 causes the incoming session for mobile communications (MT) Protocol IS-801 or FAP 120 or mobile station 110, based on the characteristics of the positioning adopted MPC 140 (stepg). The Protocol IS-801 is a positioning Protocol that is typically used in 3GPP2 networks. The Protocol IS-801 supports the positioning of the target device by using certain procedures and signaling between the target device and server location (e.g., PDE). The Protocol LCS (Location) Radio Resource (RRLP), the Protocol Control Radio Resources (RRC) and the Protocol of LTE Positioning (LPP) are protocols positioning commonly used in 3GPP networks, and can be used for positioning FAP 120 and/or mobile station 110. FAP 120 may process the session IS-801 on the basis of transparent mode, record mode, or mode rejection, as described below. The message IS-801 session IS-801 can be transported between the MFIF 130 and PDE 150 using SMS Protocol ANSI-41, and between MFIF130 and FAP 120 using SIP messages (e.g., SIP INFO). PDE 150 may return the MPC 140 assessment of the location for the mobile station 110 or FAP 120 (steph).

[0032] PSAP 170 may determine MPC 140 based on the ESRK or ESRD taken at the stage ofeand can send MC 140 Request message Position of Emergency services (ESPOSREQ), which may include ESRK or ESRD and MDN (stepi). Then MPC 140 may return PSAP 170 assessment of the location for the mobile station 110 or FAP 120 (stepj). The stages in figure 2 can be in the order different from that shown in figure 2. Moreover, for a flow rate of 200 call can also be used for other and/or additional steps.

[0033] the Location that is returned PSAP 170 from MPC 140 on stagejmay be the location of the mobile station 110 or the location of FAP 120 obtained at the stage ofg. The location of FAP 120 may be more reliable in comparison with the location of the mobile station 110 as: (i) FAP 120 may be placed by the user in a location favorable for obtaining a measurement location; (ii) FAP 120 may have an antenna, made specifically for receiving and measuring the SPS (e.g., GPS) and other signals, or can be connected with an external antenna located on the roof of the same building; and (iii) in the past could be made of numerous positioning FAP 120 with obtaining the most accurate and reliable location, stored for later use. Mobile station 110 may be only one opportunity to get the location (when step g), which may occur when the mobile station 110 may not be according to the public for measuring the location and/or satellite signals may not intensive or do not have a good geometry. In addition, mobile station 110 may use the antenna and other internal resources, which may not be ideal for measuring the location (such as GPS) that together are used for measurement location and wireless communication, and/or due to poor RF (radio frequency) environment. For these reasons, the location of FAP 120 may be more accurate and reliable compared to the location of the mobile station 110., if zone coating of FAP 120 is relatively small (for example, 50 meters or less), then the location of FAP 120 may provide a good estimate of the location for the mobile station 110, for example, better than any positioning is obtained by means of measurements obtained by the mobile station 110. In order to guarantee a best estimate of location, PDE 150 may be combined as determining the location of mobile station 110, and determining the location of FAP 120, for example, PDE 150 may use one location to confirm a different location or can average two locations.

[0034] Figure 3 shows the execution flow 300 call for routing an emergency call from the FAP using Protocol ANSI-41 in order to obtain the location of the femtocell. Stages withaforethe flow 300 correspond call this the pam with aforein the flow 200 call in figure 2. MPC 140 may determine that an emergency call comes from FAP due to the address of the MSC to MFIF 130, ID MSC to MFIF 130 or ID of a serving cell for FAP 120, which sent MFIF 130 on stagec. MPC 140 may send MFIF 130 GPOSREQ message in order to request the location of FAP 120 (stepf)., if MFIF 130 does not yet have the location of the femtocell, then MFIF 130 may request FAP 120 for the location of the femtocell (stepg), and FAP 120 may return the location of the femtocell (steph)., if MFIF 130 is the location of the femtocell, then stepsgandhcan be skipped. In any case, the MFIF 130 may return the location of femtocells in MPC 140 (stepi). MPC 140 may cause the session IS-801 between PDE 150 and the mobile station 110, if the location of the femtocell cannot be obtained from the MFIF 130 or considered as unreliable or inaccurate (stepsj,kandl). Stagesj,kandlfigure 3 can be similar to the stages off,gandhfigure 2. Stagesmandncan correspond to the stages ofiandjaccordingly, figure 2. Like figure 2, the location returned PSAP 170 on stagen3, may be the location of FAP 120 from steps withfforior months what polozenie mobile station 110, obtained at the stage ofk, or a combination of the two locations.

[0035] Figure 4 shows the execution flow 400 call for routing an emergency call from the FAP using Protocol ANSI-41 in order to obtain the location of the femtocell. Stages withaforethe flow 400 call may correspond to the stages witheforastreams 200 and 300 of the call. MPC 140 may send PDE 150 GPOSREQ message in order to request the location of FAP 120 or the mobile station 110 (stepf). PDE 150 may determine that an emergency call is coming from FAP, thanks to the address of the MSC to MFIF 130, ID MSC to MFIF 130 or ID of a serving cell for FAP 120, which sent MFIF 130 on stagecand MPC 140 on stagef. Then PDE 150 may send MFIF 130 GPOSREQ message in order to request the location of FAP 120 (stepg)., if MFIF 130 does not yet have the location of the femtocell, then MFIF 130 may request FAP 120 for the location of the femtocell (steph), and FAP 120 may return the location of the femtocell (stepi). Stageshandican be skipped if MFIF 130 already has the location of the femtocell. In any case, the MFIF 130 may return the PDE 150 the location of the femtocell (stepj). PDE 150 may cause the session IS-801 with mobile station 110, if the location of the femtocell cannot be obtained from the MFIF 130 or to consider is foreseen as unreliable or inaccurate (steps k). Then PDE 150 may return the MPC 140 the location of the mobile station 110 or FAP 120 (stepl). Stagesmandncan correspond to the stages ofiandjaccordingly, figure 2.

[0036] Figure 3 and 4 show exemplary flows calls for the use of location femtocells as the location of the mobile station. 3 and 4 also show the use of message ANSI-41 in order to obtain the location of the femtocell from the MFIF 130 for MPC 140 (flow 300 calls) or PDE 150 (flow 400 of the call). Threads calls can be used to implement an outgoing emergency call without a relay transmission service and, when the call is subjected to the following types of relay transmission service: (i) a relay transmission service from the Femto cell to the macro cell (MFIF 130 indicates MPC 140 on stagei3 or PDE 150 on stagej4 that the location is not available, leading to session incoming mobile IS-801 with the assistance of the mobile device at the stage ofk); and (ii) a relay transmission service from the Femto cell to another Femto cell (again based on the session IS-801 on stagek). For relay transmission service from the macro cell to the Femto cell, the call flow in figure 4, for example, can be used without stagesg,h,iandj

[0037] In the exemplary implementation shown in figure 2, PDE 150 may initiate a session incoming mobile IS-801 (stepgfor an emergency call from FAP 120. In one implementation, FAP 120 may process the session IS-801 on the basis of one of the following modes.

[0038] In the transparent mode, FAP 120 may transmit all messages IS-801 to and from the mobile station 110 without interpretation or modification. In this case, the message IS-801 sent PDE 150, is transmitted first MFIF 130, then FAP 120 and eventually the mobile station 110. In this way the message IS-801 sent to the mobile station 110, is transmitted through the objects in the opposite direction in order to reach the PDE 150. MFIF 130 may mark the message IS-801 particular way before forwarding FAP 120 messages so that FAP 120 were able to recognize the message IS-801 without the actual search within messages. PDE 150 may obtain an estimate of the location of the mobile station 110 by calling positioning (such as AFLT or A-GPS) in mobile station 110 using these messages IS-801 to transport and receive instructions and answers related to positioning.

[0039] In record mode, FAP 120 may intercept all messages IS-801 received from PDE 150 (via MFIF 130), and can perform posizionare is the W as if it were a mobile station 110, and may return a response message IS-801 ago PDE 150 (via MFIF 130). In the case of a relay transmission service, FAP 120 may first complete the current session IS-801. Then PDE 150 may start another session IS-801, or mobile station 110, or with the new FAP, in order to obtain the new location of the mobile station 110.

[0040] In the mode rejection, FAP 120 may reset the first message IS-801 received from PDE 150, and may return a reject message IS-801 or other message IS-801 code special argument, pointing to FAP. Deviation or other message may also carry the location of the femtocell. Subsequently FAP 120 may operate in a transparent mode and can forward subsequent messages IS-801 between PDE 150 and the mobile station 110. Mode rejection can be used to provide PDE 150 location femtocells. the location of femtocells can be used for the location of the mobile station and may be sufficient.

[0041] During initialization, FAP 120 may process the session IS-801 in accordance with one of the modes described above. FAP 120 may select the mode on the basis of various factors such as its location (e.g. urban, rural or suburban); its position and characteristics of IS-801; etc. alternatively, the mode can be sconfig the seat in FAP 120 at the time of initialization and/or can be configured or changed at any time using for example, QAM&P 134.

[0042] the Mobile station 110 can make outgoing emergency call using the base station or other FAP, and an emergency call via relay transmission service to be transferred to FAP 120. In one implementation, FAP 120 may forward all messages IS-801 received from the mobile station 110, PDE 150 through MFIF 130, for example, in order to maintain any session IS-801, which was begun before the relay transmission service. In one implementation, FAP 120 may: (i) to forward all messages IS-801 received from PDE 150 (via MFIF 130), to the mobile station 110; or (ii) reject the initial message IS-801 and forward subsequent messages IS-801.

[0043] In the second scheme for routing an emergency call, location-based femtocells can be used geographic CRDB in order to determine the appropriate PSAP. Geographic CRDB can be used to improve routing for emergency calls from the base station through intermediate positioning (which is an option in J-STD-036) without much additional effect.

[0044] the choice of the PSAP may occur either (a) when the location of FAP 120 is determined for the first time, for example at the time of initialization, or (b) when sent to an emergency call. Can be used option (b)because: he is already defined in ka is este option in J-STD-036B; uses an alarm system, which is already defined; eliminates the complications initialization femtocells; and enables the operator to manage the PSAP routing. So option (b) may provide the ability to verify the location of femtocells at the time an emergency call that may be appropriate in cases in which: (i) the initial location of femtocells was not very accurate or reliable; or (ii) FAP 120 has been moved to a new location.

[0045] Figure 5 shows the execution flow 500 call for routing an emergency call from FAP, using geographic CRDB. Mobile station 110 may make an outgoing emergency call using FAP 120 (stepa). FAP 120 may forward the MFIF 130 request emergency call (for example, SIP INVITE), which may include the MSID of the mobile station 110, ID serving cell for FAP 120 and the characteristics of the positioning of the mobile station 110 and/or FAP 120, etc. (stageb).

[0046] Then MFIF 130 may send MPC 140 ORREQ message, which may include the MSID and the characteristics of the position (MPCAP) mobile station 110, ID serving cell for FAP 120, ID MSC to MFIF 130, etc. (stagec). MPC 140 may determine that the call is coming from the FAP, for example, through recognition MSC ID for MFIF or by querying the ID of a serving cell in CRDB 142. Then MPC 140 mo is no send PDE 150 GPOSREQ message, which may include the MSID, MPCAP, ID MSC for MFIF, ID serving cell and an indication of the requested starting position (stepd).

[0047] PDE 150 may determine that the call is coming from the FAP, for example, through recognition MSC ID for MFIF or by querying the ID of a serving cell in BSA 152., if the ID of a serving cell found in the BSA 152 and associated location is considered to be reliable (for example, it was recently updated in BSA 152 due to previous location request femtocells), then the PDE 150 may proceed to stepi. Otherwise, PDE 150 may send MFIF 130 SMS Delivery Point to Point (SMDPP), which may include Message Data Position measurement (PDDM) using IS-801, MSID and ID of a serving cell (step e). PDDM Protocol (IS-801 may ask you already know the location of the femtocell. PDE 150 may also specify the Location of the Base Station in the Pointer parameter, using the new value of the ANSI-41 in order to inform MFIF 130 that PDDM Protocol (IS-801 is FAP 120, and not the mobile station 110.

[0048] MFIF 130 may recognize the value of "Location Base Station" ANSI-41 Index Services. In response, MFIF 130 may send FAP 120, a Request message for a Location, which may include the contents of the SMDPP message, received from the PDE 150 (b> f). MFIF 130 may determine FAP 120 ID of a serving cell or MSID adopted in the SMDPP message. Then FAP 120 may return the MFIF 130 Response Location, which may include the MSID, ID serving cell and the answer PDDM Protocol (IS-801 (stepg)., if FAP 120 does not support the Protocol IS-801 except for the minimum response, then it can return the standard (fixed format) unsolicited response PDDM Protocol (IS-801, which may include the known location of femtocells., if FAP 120 supports the Protocol IS-801, then it can return more than the correct answer Protocol (IS-801, which may include its known location, or equivalent information, such as measurements, based on which the PDE 150 may determine the location of femtocells. the location of femtocells may contain the exact coordinates of the location of FAP 120 and the accuracy of these coordinates. The error may be variable (for example, by means of FAP 120) to include coverage FAP 120 and may, respectively, to indicate the possible location of the mobile station 110. Stagesfandgcan be skipped if MFIF 130 already has the location of the femtocell.

[0049] MFIF 130 may send PDE 150 SMDPP message, which may include a response from FAP 120 (steph). PDE 150 may cause complement the performance communications stages, such steps witheforhthat is, if the stagehthe location of femtocells has not been provided, and FAP 120 supports the Protocol IS-801. For example, PDE 150 may cause AFLT using the Protocol IS-801, in order to obtain the location of the femtocell. Then PDE 150 may return the MPC 140 the location of the femtocell (stepi). MPC 140 may update BSA 152 in accordance with the location of femtocells, for use in subsequent requests location. MPC 140 may access CRDB 142 in order to determine the correct PSAP (e.g., PSAP 170) for the location of femtocells, taken from PDE 150. MPC 140 may appoint ESRK, or may determine ESRD, for the selected PSAP 170. Then MPC 140 may send MFIF 130 is ESRK or ESRD (stagej). MFIF 130 may route the call to PSAP 170 on the basis of ESRD or ESRK (stagek). PSAP 170 may determine MPC 140 based on the ESRK or ESRD, and can send MPC 140 ESPOSREQ message, which may include ESRK or ESRD, and MDN (stepl). MPC 140 may determine that the location of femtocells, adopted at the stage ofithat is fairly accurate as the original location of the mobile station, and can return the location of the femtocell PSAP 170 (stepm).

After steph, PDE 150 may cause additional stages similar to the stages witheforhif at the stage ofhthe location of femtocells has not been provided, and FAP 120 supports the Protocol IS-801. For example, PDE 150 may cause AFLT using the Protocol IS-801 in order to get to the nearest location femtocells., if the location of femtocells accurate enough for routing, but not for sending an emergency call, then the PDE 150 may return the MPC 140 location femtocells in the message indicate the Geographical Position (GPOSDIR), in accordance with what is defined in J-STD-036B to support intermediate location (stepi). PDE 150 may also update BSA 152 in accordance with the femtocell locations for use in a subsequent request location. MPC 140 may confirm receipt of the message GPOSDIR (stagej).

[0051] Stepskformthe flow 600 call phases withjforlthe flow 500 call. On stagenif FAP 120 supports the Protocol IS-801, then the PDE 150 may cause the stages similar to the stages witheforhfor the new session IS-801 in order to get the exact location of FAP 120, for example, used is isua A-GPS and/or AFLT. if the final location of the femtocell is accurate enough, then the PDE 150 may skip stages withofortand may proceed to stepu., if stepsofortare met, then they may occur after stepntonin parallel with stepnor instead of stepn.

[0052] If stepnnot performed, or if the final location of femtocells was not sufficiently accurate, or, if PDE 150 is required to get location as FAP 120, and the mobile station 110, then the PDE 150 may cause the session IS-801 with mobile station 110 based on the characteristics of the positioning of the MS received from MPC 140 on staged. PDE 150 may start sending MFIF 130 SMDPP message, which may include the message IS-801, MSID, ID serving cell and the Index of Services, indicating the Positioning of CDMA, in accordance with what is defined in J-STD-036B (stageo).

[0053] MFIF 130 may recognize the importance of Positioning CDMA for Index Services. MFIF 130 may verify that the mobile station 110 is still served by the FAP 120., if this is not the case (for example, because the relay transmission service), then MFIF 130 may forward the SMS message to the new FAP served MFIF 130, the new serving MSC, or a new service MFIF, depending on where he was Perea is resown emergency call in the relay transmission service., if the call was not forwarded from the relay transmission service, then MFIF 130 may send FAP 120 message, which may include the contents of the SMDPP message (stepp). FAP 120 may redirect the message IS-801, taken from the MFIF 130 in message 1x Packet Data, the mobile station 110 (stepqand she can be informed about the value of the message IS-801. Mobile station 110 may perform any method of positioning that can be requested in the message IS-801 and may return FAP 120 answer IS-801 message 1x Packet Data (stepr). The answer IS-801 may include any measurement of positional information for positioning, which can be queried PDE 150 may include a request for information and auxiliary data from the PDE 150. FAP 120 may redirect the message IS-801 together with the MSID and ID of a serving cell to MFIF 130 inside the SMS message (steps).

[0054] MFIF 130 may send PDE 150 SMDPP message, which may include a forwarded message IS-801, MSID, ID serving cell ID for MSC MFIF and Index Services, indicating the Positioning CDMA (staget). PDE 150 may cause additional steps, for example, such steps withoforqto request more information and/or more measurements from the mobile station 110 using duct is l IS-801. Mobile station 110 may cause the stages similar to the stages withrfortin order to provide additional measurements and/or information PDE 150 and/or to request additional information (e.g. satellite data) from the PDE 150 using the Protocol IS-801.

[0055] once the stages withnfortcompleted, PDE 150 may determine the location of the mobile station using any results location received from the mobile station 110 in stages withofortand/or any location obtained for FAP 120 on stagenand/or stages witheforh. For example, the location of femtocells obtained at the stage ofnand/or stages witheforhcan be used to help verify the location of the mobile station from steps withofortor Vice versa. In addition, different results positioning can be combined, for example averaged. PDE 150 may send MPC 140 the location of the mobile station in the gposreq message (stepu). MPC 140 may send PSAP 170 the location of the mobile station (stepv).

[0056] the Procedure of determining the location in the call flows of Fig. 2 through 6 may be applied in different scenarios relay transmission rinse the deposits. For relay transmission service from Femto to macro, mobile station 110 may make an outgoing emergency call using FAP 120, and the relay transfer of an emergency call may occur to the base station. PDE 150 may still obtain the location of FAP 120 and may use the location of femtocells, for routing, as well as the original location of the transmission. PDE 150 may obtain the location of mobile station 110, in contrast to FAP 120, for any request for updated location to avoid errors accompanying the relay transmission service. The session IS-801 may be incomplete at the time of a relay transmission service or may be initiated after the relay transmission service. In this case, the message IS-801 from PDE 150 may be diverted from the MFIF 130 to the serving MSC in messages SMDFWD Protocol (ANSI-41. Mobile station 110 may receive messages IS-801 and continue the session IS-801 with PDE 150.

[0057] For relay transmission service from macro to Femto mobile station 110 may make an outgoing emergency call using the base station. PDE 150 may cause the session IS-801 with mobile station 110 in order to obtain accurate source location and update the location. An emergency call can be transmitted by the relay transmission is e services to FAP 120. PDE 150 may not be able to get the location of the new FAP 120, for example, for use as the location of the mobile station. The session IS-801 may be incomplete at the time of a relay transmission service or may be required after the relay transmission service. In this case, the message IS-801 from PDE 150 may be diverted from the reference base station MSC to MFIF 130, which may forward these messages FAP 120. Then FAP 120 may miss the message, the mobile station 110. Just FAP 120 may return the PDE 150 all the answers IS-801 sent to the mobile station 110.

[0058] For relay transmission service from the Femto to Femto mobile station 110 may make an outgoing emergency call using the FAP 120, and PDE 150 may receive the location of FAP 120 and may use the location of femtocells, for routing, as well as the original location of the transmission. An emergency call can be transmitted by the relay transmission service new FAP. PDE 150 may always obtain the location of mobile station 110, instead of any FAP to any request for updated location, in order to avoid errors accompanying the relay transmission service that may arise with this type of relay transmission service. The session IS-801 may be incomplete at the time the relay p is to provide service or may be initiated after the relay transmission service. In this case, the message IS-801 can be transferred from PDE 150 to the new FAP through MFIF 130 (if MFIF has not changed) or through MFIF 130 and serving MFIF (if the new FAP uses a different MFIF). New FAP can process messages IS-801, for example, such as when the relay transmission service from macro to Femto.

[0059] In another aspect, FAP 120 may perform positioning using the Protocol IS-801 during initialization and/or at periodic intervals of time. The original location of FAP 120 may be received in connection with OAM&P 134, as part of the authorization Femto cell, the accompanying power-on and authentication, for example, in order to ensure that the FAP 120 is placed in a licensed operator area. The location of FAP 120 may be updated at periodic intervals of time or, if necessary, in order to improve the accuracy and to identify any movement FAP 120.

[0060] the Source and updated the location of FAP 120 may be obtained using one or more of the following:

The SPS receiver in FAP 120, which uses, for example, stand-alone SPS positioning

The observed macro cell base stations and/or Femto cells/access points whose location is known OAM&P 134,

Address subscription for the mobile station or user,

- The public IP address assigned to the FAP 120 service provider,

Session MT IS-801, for example, with A-GPS and/or AFLT positioning in FAP 120.

[0061] Fig.7 shows the execution flow 700 call to get the location of the femtocell using the Protocol IS-801. The flow 700 can be used for the first schema associated with 2, 3 and 4. FAP 120 may send MFIF 130 location request and can provide IS-801 location (MPCAP), MSC ID macrosty, ID macro cell, and so on (stepa). Location can be AFLT, A-GPS, etc. if the source location of FAP 120 is still not obtained, and if the FAP 120 is not able to observe signals from any of the surrounding macro cell, then FAP 120 may not provide ID MSC macrosty and ID of the macro cell. In this case, temporarily OAM&P 134 or MFIF 130 may be assigned ID MSC macrosty default ID and the macro cell by default. These ID MSC macrosty ID and the macro cell may or may not be provided in CRDB 142 and BSA 152. In any case, the MFIF 130 may emulate MPC and can send PDE 150 GPOSREQ message, which may include MPCAP, ID MSC macrosty and ID of the macro cell (stepb). The GPOSREQ message can also include special MSID (e.g., fixed ESN) to specify FAP.

[0062] PDE 150 may take the GPOSREQ message and can recognize special MSID indicating FAP., E. the ID MSC macrosty and ID of the macro cell found in the BSA 152, then PDE 150 may cause the session IS-801 in order to start suitable positioning (for example, AFLT and/or A-GPS) in order to position FAP 120 (stepc)., if BSA 152 ID not found MSC macrosty and ID of the macro cell, then PDE 150 may initially be run AFLT without providing any supporting data in order to obtain information for the neighboring macro cells, and can then use one or more of these macro cell in order to maintain the session IS-801. Alternatively, for example, if not detected macro cell, then PDE 150 may provide supporting data A-GPS, based on a rough assumption of the location of the femtocell (e.g., based on known service area MFIF 130). Positioning A-GPS can take a long time due to less accurate assistance data for A-GPS. During this session, IS-801, PDE 150 may process the FAP 120 a manner similar to that mobile station, to provide auxiliary data FAP 120, and requesting measurement for FAP 120. Accordingly, in view of the Protocol IS-801, PDE 150 may keep the regular role of PDE Protocol (IS-801, while the FAP 120 may act as a mobile station.

[0063] After completion of the session, IS-801, PDE 150 may return the MFIF 130 assessment location for FAP 120 (stepd). PDE 150 may be encrypted and/or digitally the way the assessment location, using an encryption key known OAM&P 134, but is not known FAP 120, and possibly using other information such as the current date and time, MEID for FAP 120, etc. Encryption and/or digital signature can prevent imitation of the location. femtocells MFIF 130 may return to assess the location of FAP 120 (stepe). Then FAP 120 may provide OAM&P 134 evaluation of the location, if the estimate of the location was encrypted and/or digitally signed, then OAM&P 134 can decrypt it and/or clean the authentication and make sure that the location has been obtained by means PDE 150. Moreover, to further provide an estimate of the location of the new PDE for an emergency call (for example, as part of the Rejection message Protocol (IS-801 from FAP 120), the original encrypted and/or signed with a digital image of the location can be used to allow the new PDE to authenticate it.

[0064] Fig shows the execution flow 800 call to get the location of the femtocell using the Protocol IS-801. The flow 800 can be used for the second schema associated with figure 5 and 6. FAP 120 may send MFIF 130 location request and can provide your location IS-801 (MPCAP), your MEID, an ID of a serving cell and so on (stepa). MFIF 130 may morovati MPC and can send PDE 150 GPOSREQ message, which may include the ID of MSC to MFIF 130, MPCAP, MEID and ID of a serving cell FAP 120, etc. (stageb). The GPOSREQ message also can include the Type parameter of the Query Position, installed in value in order to specify a query for the location of femtocells.

[0065] PDE 150 may take the GPOSREQ message and can recognize the value Type of the Query Position. PDE 150 may cause the session IS-801 with FAP 120 by sending MFIF 130 SMDPP message, which may include PDDM Protocol (IS-801, MEID and ID of a serving cell FAP 120, etc. (stagec). PDE 150 may also specify the Location of the Base Station" in the Index of Services.

[0066] MFIF 130 may take the SMDPP message and can recognize the value of "Location Base Station" in relation to the Index Service. MFIF 130 may determine FAP 120 of the ID of a serving cell or MEID in the SMDPP message. MFIF 130 may send FAP 120, a Request message for a Location, which may include the contents of the SMDPP message (stepd). FAP 120 may receive measurement positioning in accordance with what is requested PDE 150, and can send MFIF 130 Response Location, which may include the response IS-801, MEID and ID of a serving cell FAP 120, etc. (stagee). The answer IS-801 may include measuring the positioning and/or information for positioning the requested PDE 150. FIF 130 may forward PDE 150 answer IS-801 in the SMDPP message (step f). PDE 150 may for a session IS-801 to treat FAP 120 such as a mobile station.

[0067] PDE 150 may cause additional stages similar to the stages ofcanddto request more information and/or measurements for FAP 120, using the Protocol IS-801. FAP 120 may cause additional stages such as stageseandfin order to provide PDE 150 additional measurements and/or information and/or to request information (e.g. satellite data) PDE 150 using the Protocol IS-801. Then PDE 150 may return the MFIF 130 calculated location (stepg) femtocells. Assessment of the location may be encrypted and/or digitally signed by PDE 150 or may be sent unencrypted and unsigned. PDE 150 may update BSA 152 in accordance with the location of femtocells for use in subsequent requests location. MFIF 130 may return the estimate of the location of FAP 120 (steph). FAP 120 may provide OAM&P 134 evaluation of the location.

[0068] As described above for figure 2, the location of FAP 120 received in accordance with 7 and 8, can be accurate and reliable. In particular, PDE 150 may provide FAP 120 auxiliary data (for example, for positioning A-GPS, A-SPS or AFLT) or 7, or 8, in order to increase echnosti and reliability. The procedure IS-801 and provided supporting data may be similar to those provided when PDE 150 positions the mobile station (for example, mobile station 110). However, for the reasons described above for FAP 120 may be obtained more reliable and accurate location in comparison with the mobile station.

[0069] Fig. 2 through 8 show an exemplary call flows, illustrating the various characteristics described here are methods. The techniques also can be implemented using other threads call, which may have the steps different from those shown in Fig. 2 through 8.

[0070] Figure 9 shows the execution of a process 900 performed by the mobile station. The mobile station may send FAP message in order to make an outgoing emergency call, for example, at the stage ofaFig. 2 through 6 (block 912). An emergency call can be connected to the emergency communication center (e.g., PSAP), selected on the basis of the information of the location for FAP. The mobile station can communicate with the PDE in order to obtain an estimate of the location for the mobile station, for example, at the stage ofg2 or stagek3 and 4, (block 914). Upon request, estimate of location can be provided to the emergency operations centre. The mobile station can communicate with the emergency operations centre for EXT the military call (block 916).

[0071] Figure 10 shows the execution of a process 1000 performed FAP to support an emergency call. FAP may receive the first message sent by a mobile station, in order to make an outgoing emergency call, for example, at the stage ofaFig. 2 through 6 (block 1012). FAP can send MFIF (or some other object network) the second message to initiate an emergency call, for example, at the stage ofbFig. 2 through 6 (block 1014). FAP can also send MFIF (or some other object network) the location information for the FAP, for use in the selection of the center of emergency communication to an emergency call, for example, at the stage ofg5 and 6 (block 1016).

[0072] In one implementation, the FAP may determine its location during initialization and may receive the location information identified based on their location. In one implementation, the FAP may communicate with the PDE to obtain for themselves during the initialization of the estimation of the location and information of the location may include an evaluation of the location. In another implementation, the information of the location can contain the ID of the macro cell, which can be determined based on the location of the FAP. For example, the ID of the macro cell may correspond to a macro cell, which has an intense signal in the FAP and the and which is overlapping with the FAP coverage. Information of the location in addition may contain ID MSC macrosty, which can be determined based on the ID of the macro cell. Information location can also contain other types of information determined based on the location of the FAP.

[0073] In one implementation, the FAP may send the location information in the second message in block 1014. In another implementation, the FAP can take from the MFIF to the request for determining the location of the FAP, for example, at the stage off5 and 6. Then FAP can send MFIF the location information in response to the request, for example, at the stage ofg5 and 6. Accordingly FAP may send the location information in the original message sent MFIF in a subsequent message sent MFIF.

[0074] In one implementation, the FAP may communicate with the PDE to obtain the estimate of the location once initiated outgoing emergency call, for example, at the stage ofgfigure 2. Assessment of localities for FAP can be used as an estimate of the location for the mobile station and may be granted, on request, to the emergency operations centre. In one implementation, the FAP can accept the location request FAP from the object network and can send the object network with its assessment of the location, for example, stagesgandh3, or stageshandi figure 4. In one implementation, the FAP can forward messages that are exchanged between a mobile station and PDE, in order to obtain an estimate of the location for the mobile station after the initiated outgoing emergency call. Assessment of the location for the mobile station can be provided, on request, to the emergency operations centre. In accordance with what is described above, the FAP may support positioning for themselves and/or the mobile station by other means.

[0075] 11 shows the execution of a process 1100 performed MFIF to support emergency calls. MFIF may receive the first message sent by the FAP, in order to initiate an emergency call to the mobile station, for example, at the stage ofbFig. 2 through 6 (block 1112). MFIF may receive the location information for the FAP, for example, at the stage ofbFig. 2 through 4 or stageg5 and 6 (block 1114). MFIF may send to the first network object (for example, MPC or PDE) the second message containing the location information for the FAP, for example at the stage ofcfigs 2, 4 or stageh5 and 6 (block 1116). Information location for FAP may contain the ID of the macro cell and possibly ID MSC macrosty defined on the basis of the location of the FAP, the assessment of the location for FAP and/or other information identified on the basis of which mestopolojenie FAP. Information location for FAP may be included in the first message sent by the FAP (e.g., as shown in figure 5 and 6). In any case, information of the location for FAP can be used to select center emergency communication to an emergency call.

[0076] MFIF may receive from the second network object (e.g., MPC), the third message containing the routing information for the emergency operations centre, for example at the stage ofdFig. 2 through 4, the stagej5 or stagek6 (block 1118). The first and second network entities can be the same or different network objects. Routing information may be determined based on the information location to FAP and may contain ERSK, ERSD and/or other information. MFIF may forward the emergency call to the emergency communication center based on the routing information, for example, at the stage ofeFig. 2 through 4, the stagek5 or stagel6 (block 1120).

[0077] MFIF may receive the location request FAP from the first or second object network, for example at the stage off3 or stagegfigure 4. MFIF may provide the location of the FAP to the first or second object network, if permissible, without the implementation of the request to the FAP, for example at the stage ofi3 or stagejfigure 4. MFIF may support positioning FAP and/or mob is through the station.

[0078] Fig shows the execution of a process 1200 performed by the MPC to support emergency calls. MPC can receive the first message sent MFIF (or some other object network), in order to obtain the routing information to the emergency operations centre emergency call originating from the mobile station via the FAP, for example, at the stage ofcFig. 2 through 6 (block 1212). MPC can also take the location information for the FAP, for example, at the stage ofcFig. 2 through 4, or stagei5 and 6 (block 1214). MPC can determine the routing information to the emergency operations centre on the basis of the information of the location for FAP (block 1216). Then MPC can send MFIF (or some other object network), the second message containing the routing information, for example, at the stage ofdFig. 2 through 4, the stagej5 or stagek6 (block 1218).
