The technical field to which the invention relates.
The present invention relates to a method and system for determining location, which are designed to determine the location of the wireless terminal in a cellular network.
The level of technology
System location using one or more positioning technologies to determine the location of the terminal, as a mobile station, a subscriber unit or the radio terminal of any other type. Positioning a given terminal includes measuring signal and calculating an estimate of the location on the measured signals. Assessment of the location or positioning usually gives the geographical location of the mobile station and/or operating mobile equipment in the form of data of latitude and longitude. Assessment of the location can be represented in a given universal format.
Technology positioning systems positioning (COM, LCS) as part of a cellular network, a global system for mobile communications (GSM) can be implemented on the basis of the method, determining the time of arrival (AFP, TOA) of the signal uplink communication methods by determining the difference between the times (ODS OTD) of a signal (for example, ORITS, OTDOA or process for high-OTD (- RIA, E-OTD), the method using global is Noah positioning system (GPS), method of identifying the cell (S, CI), query register location in the network (ROMAS, HLR) or register determine the location of the visitor network (ROMS, VLR), or any combination of the mentioned methods. As a backup procedure to support any of the mentioned positioning technologies, in addition to positioning using ROMAS/ROMS (HLR/VLR) (registerprocedure subscriber location network or registerprocedure location of the visitor network), you can use the parameter timing synchronization (CB, TA). The OS is usually known for serving base transceiver station that provides the value of the asset for a given mobile station in idle mode. A special call, which does not notify the user or subscriber of the mobile station is set using the search procedure call (paging), for example, not a real challenge, and in response to this call are transmitted S (CI) (cell ID) of a serving cell and OS.
In GSM, in accordance with the positioning method according to the AFP signal uplink communication is measured arrival time of a known signal transmitted by the mobile station and received at least three measuring modules. The known signal is a packet data access generated by running mobile with what anzia asynchronous transfer service. To accurately measure the arrival time of data packets, the method requires a host, in the geographic vicinity of the mobile station, additional equipment, component measuring module, i.e. the module location measurement (MIM, LMU). Because the geographic coordinates of the measuring modules are known, the position of the mobile station can be calculated in the main center placement method hyperbolic triangulation.
Furthermore, the method In the RIA is based on running a mobile station, the measurement precision of the difference of times of arrival of data packets adjacent pairs of base transceiver stations (BPS, S). To ensure accurate triangulation measurements-ODS, you must perform at least three different pairs of geographically dispersed BPS. The location of the mobile station can be calculated from the measured values In the RIA, either online or in the mobile station if the mobile station has all the necessary information.
Way on the basis of the GPS assumes any one of several variants that use GPS signals or complementary signals received from the GPS signals, to calculate the coordinates of the mobile station.
The location system is logically implemented in a cellular network using additional network node: center definition is mestopolojenie mobile terminals (COMT, MLC). In particular, tools firewall centre location of mobile terminals (MCOMM, GMLC), representing the first node in the cellular network that is accessed by an external client. Firewall-center positioning of mobile terminals (MCOMM) requests routing information from the register location in the network (ROMAS), authorizes registration, transmits the positioning request to the network and receives an estimate of the location of the network. In addition, equipped service center location of mobile terminals (IOMT, SMLC), which manages the overall coordination and scheduling of resources required to perform positioning or determining the location of a mobile or wireless terminal. This center also calculates the final assessment of the location and its accuracy. One cellular network can contain multiple IOMT and COMMT.
The so-called IOMT-based navigation satellite service (NSS, NSS) supports the positioning of the given mobile station by sending a signal in a freely available switching center mobile terminal (CMT, MSC), and the so-called IOMT on the basis of the broadcasting-satellite service (RCC, VSS) support positioning by sending a signal to pin the Oller base stations (KBS, BSC)serving a given mobile station. Both types IOMT can support the communication interface to provide access to information, which has another IOMT.
IOMT manages a group of MIM for the interface of the radio channel measurement data to determine or support the positioning of mobile stations in the area that caters to this center. The signals exchanged between IOMT on the basis of NSS and MIM are transferred through CCMT serving MIM, and the signals exchanged between IOMT on the basis of the RCC and MIM are transferred through the controller KBS, which serves MIM or manages impunzi IOMT and COMMT can be combined in the same physical node from among the existing physical nodes or distributed over several nodes in a cellular network.
A more detailed description of known systems location listed in technical specification GSM 03.71.
The document EP 0905992 A1 describes procedures for determining location when location requests are transmitted to the mobile terminal. A crucial module in the mobile terminal is configured to measure the quality level of the received radio signals and activate special functions positioning when the measured quality level falls below a predetermined level. On the fact the procedure of positioning depends on the quality of the received radio signals and allows to achieve a high probability of success.
In these traditional systems, location, each location request creates a heavy load on the network function associated with the transmission of signals, by calculating the location and dimension. Therefore, for the organization of the global positioning system (COM, LCS) in the network should provide sufficient bandwidth for transmitting signals and centralized computing and/or measuring power. However, SOMS with known configurations no longer able to handle the required number of location requests per second in accordance with the requirements of the operator.
For this reason, the present invention is a method and system for determining the location by which you can increase network throughput by location requests.
This task is solved by the method of determining the location of a wireless terminal in a cellular network in response to the location query, which consists in the fact that the location request includes information about the quality and information quality determines the required quality of services, information about the quality control in the channel transfer request location in a cellular network, and on the basis of information about the quality chosen by the network element, the which to determine the location of the wireless terminal.
Although the quality requirements are already taken into account in known procedures, positioning, use them only when you select the local methods. In practice, this means that the parameters of quality of services (QU) Bits are used only in configurations RCC and NCC to select the applied method. In contrast to the above, in accordance with the present invention, the logic selection can be distributed throughout the network, namely, MCOMM (positioning on the basis of zones ROMAS/ROMS), CMT (positioning based on ASC), ASC (positioning of OIA, and, in addition, in some cases, technology-ODS and tools GPS) and mobile stations (MS, MS) (positioning based on MS technology-ODS and using GPS). In this approach, the calculation can be performed by a device that is optimal from the point of view of the required accuracy and use of network resources.
In addition, the aforementioned task is solved by a network element to request location at a crucial network element that defines the requested location of the wireless terminal, containing
control means for controlling the quality information included in the location request, with information about the quality determines the required quality of services and
the tool of choice for you is ora casting network element on the basis of information about quality.
In addition, the above-mentioned problem is solved by the system to determine the location of the wireless terminal in a cellular network in response to the location request containing the service functional tool to include information about the quality of the location request and the network element to select on the basis of information about the quality of a network element, which defines the location of the wireless terminal, and for sending a location query to the selected network element and the network element is configured to receive the location request and location in response to the location request.
In accordance with the present invention known to the centralized configuration of the positioning is improved by distributing the computing power of positioning. In addition, the transfer of location requests can be aborted at the earliest possible stage in accordance with the quality of service (KU)required by the location service. Location data can be calculated in several places or network elements, and not necessarily always should be sent to the radio access network. Thus, the load on the transmission of signals is reduced, because some requests position is the position it is possible to in paragraph networks located closer to their source, and they are not necessary to send along the route in the radio access network. The distribution computing means provides reduction of the computational load on the network element.
In a preferred embodiment, the required quality of service is used when choosing the method of determining the location defined on the basis of accuracy and/or response time specified with quality services. Thus, the query location with a low requirement on the accuracy and/or demand a quick answer do not necessarily should be sent to the end in the radio access network, and can be processed in the base network.
If information about the quality necessitates a rapid response time and low accuracy, the location of the wireless terminal can be defined in a network element of the core network. In particular, the center MCOMM or center CMT can be a network element that can determine the location ID of the cell. This location can be determined using CAMEL (special application program for advanced logic network for mobile communication) or the location information obtained from the query ROMAS or ROMS.
Preferential modifications or additional variants of the invention are formulated in the dependent clause is the claims.

Figure 1 is a block diagram of a conventional system location in which all location requests are sent to the radio access network;
Figure 2 presents a diagram depicting the various ways of positioning their response times and accuracy;

Description of the preferred option of carrying out the invention
Below is a description of a preferred variant implementation of the invention on the example of the configuration of the COM, in which the positioning requests sent from the client 40 KGS in COMMT 30 reference network.
Figure 1 shows CATFISH traditional configuration, in which all location requests coming from external client 40 KGS, sent using COMMT 30 through the element 20 of the core network, for example, CCMT second or third generation in the Ostrava core network, based on GSM, or serving support node of the packet radio services General purpose OPUP, SGSN) second or third generation included in the base network-based system of services packet radio for General use (GPRS)in the radio access network (Wed, RAN) 10 containing IOMT. Wed 10 may be a DDS GPRS (GERAN) or ground DDS standard UMTS (universal mobile telecommunications system) (UTRAN). Routing is performed COMMT 30 can be based on the request to the internal subscriber database, for example, the internal subscriber server (YOU, HSS) 50. Thus, as shown in figure 1, the calculation function of location is a centrally on Wed 10.
However, it is highly likely that the majority of services in the location requested by an external client 40 KGS, can be performed with limited precision (e.g., a method based on S), and only a few services require the use of more precise methods that require operations in the corresponding mobile terminal 1 or the DDS 10. Therefore, in accordance with the preferred embodiment of the invention the load required to determine the location, you can distribute in accordance with the quality of service required by the location service. To achieve this, and the information about the quality attached to the message to request the location of the mobile terminal. Information about the quality you can include or attach a location request coming from the client 40 KGS. Information about quality can be set or specify the required specifications and can be used for selection of the appropriate or the most appropriate way to determine the location and, therefore, the place where you want to determine or calculate the location.
Figure 2 presents a diagram depicting the various ways of positioning their response times and accuracy. Furthermore, the arrow indicates where the network can implement the appropriate way. In accordance with figure 2 methods of locating or positioning based on GPS are implemented in the mobile terminal 1 (or KBS/controller network communication (DAC, RNC), and the ways ODS are implemented in the base station controller (ASC) (or mobile terminal) PSA 10. Methods based on the OIA can be implemented in ASC/DAC CCMT or OPUP core network 20 or MCOMM 30. Positioning on the basis of zones of ROMS/ROMAS can be performed in the center COMMT. In addition, as can be seen from figure 2, high-precision positioning (i.e. with an accuracy of better than about 100 m) should be performed on Wed 10 when the assigned greater the required response time to retrieve the result. On the other hand, the positioning with low precision (i.e., f is d worse than about 100 m) can be performed in the core network and thus it is possible to reduce the response time.
Thus, it is possible to make a decision about where to process requests for location, MCOMM 30 or other suitable switching element of the core network, to send in PSA 10 only such queries locations that provide an appropriate level KU, i.e. high precision and/or a large response time. So you can handle and calculations for some queries location already in COMMT 30 or CMT, or OPUP core network 20.
In accordance with a preferred embodiment of the invention can be formulated the following model of load distribution depending on the required level KU:
The requirement level of the KU type A quick response time, low accuracy”:
If information about the quality, added to the query location, indicates the above requirement, are the most suitable ways on the basis of the OIA or areas of ROMS/ROMAS. Therefore, the calculation may be performed or initiated in COMMT 30 or in the system configuration on the basis of NSS (i.e CCMT or OPUP core network 20). The necessary location information may be requested function CAMEL (special application program for advanced logic mobile network) (e.g., ATI) or is in any other suitable way.
The requirement level of the KU type In “high fidelity, great response time”:
If the location request contains the above information about quality, then you want to use more sophisticated ways of positioning. Therefore, the location request is sent to DDS 10, and starts the execution of the necessary measurements and calculations.
Probably the majority of the locations will include the requirement for level RL of type a, and this means that most calculations to determine the location will be completed or started in COMMT 30. It allows you to partially withdraw from the DDS 10 overhead associated with the computation and transmission of signals.
Figure 3 is a schematic diagram of the COM in accordance with the preferred embodiment of the invention. Requests CATFISH, outgoing from the client 40 KGS, sent to the center COMMT 30. The client 40 KGS may contain SOM, United, at least one client, which can provide location services through the use of location information. Usually the client 40 KGS is a logical functional object that requests location information from a given set of parameters, for example the level of KU, for at least one of the desired mobile terminal or mobile station. The client 40 COM m which may be in the composition of the object within the network or in the structure of the external object with respect to a cellular network. The client 40 KGS made with the ability to add, activate, or attach information about the quality, which indicates the required level of KU and passes the request to the location in COMMT 30. Then the control function COMMT 30 extracts and validates the information as to determine a suitable location for positioning. On the basis of the result of this control operation selector provided for in part COMMT 30, selects a suitable place to perform actions on the positioning. This choice can also be a choice of one of the two networks, second or third generation (2G/3G).
Figure 4 is a sequence diagram implement the functions of control and choice in COMMT 30. After step S100 received the location request, it is passed to the control function, which determines the type of the desired level of KU at step S101. Based on the level of KU, for example level RL of type A or type B is the branching procedure at step S102. If the detected level RL of type A, then the procedure goes to step S103, in which it starts the calculation or determination of the location in COMMT 30, for example, by sending a location request to the server 60 of the positioning, which provides information required to implement the method of position the Finance on the basis of OIA (or zones ROMS/ROMAS). On the other hand, if the detected level RL of type B, then the procedure goes to step S104, at which the location request is sent through COMMT 30 Wed 10 for more accurate positioning.
It should be noted that the control or decisive function and the selection function can be implemented using appropriate software control program which controls the CPU provided in the composition COMMT 30, or can be implemented in the form of corresponding discrete hardware features COMMT 30.
Because the majority of CATFISH are terminated at the earliest possible stage, there is a reduction of the load on other elements of the communication network. In addition, the computational load is thus distributed over the network, which reduces the computational load on the network element.
In the case of dual-mode terminals, subject to the restrictions on the simultaneous use of the GSM system and network standard WCDMA/GPRS (broadband communication systems with multiple access, code-division multiplexing (SMDR)/system General packet radio use) or other means. In practice, this means that connections to the network standard WCDMA/GPRS suspended if location or call the mobile terminal is carried out in the GSM system. P is this control and designation on the basis of quality in accordance with the proposed invention can be realized, in order to make decisions about selecting or local way of locating or positioning, for example, location-based OIA network standard WCDMA, or an improved method for positioning other system terminal.
In particular, MCOMM 30 may receive a location request from the client 40 KGS. This request includes, for example, the subscriber number of the user, the location of which you want to define, and the required level of KU. Level RL is stored in COMMT 30 for subsequent use. Then COMMT 30 sends a request in the internal subscriber base 50 data, such as ROMAS, to determine the appropriate network element in the base network serving the subscriber. COMMT 30 may receive a response from the internal subscriber base 50 of the data, which indicates that the subscriber maintains an active connection to a network that does not belong to the GSM system (for example, network standard WCDMA). In addition, the terminal connected to the network system GSM. First, apply a “local” ways of positioning, for example, the location request is routed in the underlying network in which the terminal operates. For example, MCOMM 30 may send a location request to the core network of the third generation (3G). The core network uses the active service of signalin the th channel to request location in the radio access network, for example, in the DAC (the controller of the radio communication network). This element is a radio communication network performs associated with CATFISH operations, which can be embedded in it. It should be noted that these operations may or may not provide the level requirement KU, installed in the location request. Assessment of the location is transmitted back to the base network settings CATFISH, which may include the coordinates of the terminal, OIA, etc. in Addition, the response includes the achieved estimation accuracy of positioning.
The core network transmits the evaluation COMMT 30, which checks whether the requirement SPECIFICATIONS. If the requirement KU are not met, then COMMT 30 passes the request to the SOM in CMT (switching center mobile terminal) of the GSM network, which generates a signaling channel to the terminal and sends the request to the servicing ASC or IOMT. While ASC or IOMT has an open signaling channel to the terminal and therefore able to include measurements of SOM. IOMT calculates location technology-RIA, A-GPS (with GPS) or similar methods. Assessment of the location is transmitted back to CMT, which sends a new assessment in COMMT 30. COMMT 30 transmits the most appropriate to assess the location of the client 40 KGS.
Thus, in appropriate cases, can be OEM home button Flex cable is treny improved ways of positioning or location in the GSM system. It should be noted that in case of implementation of requirements to the level of KU procedures CATFISH can be stopped, when the local positioning system receives its first assessment of the location. However, if the requirement level KU fails, then COMMT 30 is able to operate a GSM network to improve accuracy.
It should be noted that the present invention is applicable to the COM any configuration in which the location request is routed through the centralized network elements in a special functional units of the positioning. In addition, it should also be noted that information about the quality (Q) is not necessarily included in the original location request received COMMT from the application of the COM. In this case, MCOMM may include information about the quality depending on the specified dynamic load on the network and/or other specified parameters. Moreover, the above backup procedure, supporting improved ways of positioning or location, can be used with any other network system and, therefore, does not imply limited use as a backup procedure for the GSM system.
