The technical FIELD TO WHICH the INVENTION RELATES.

Embodiments of the invention generally relate to mobile communication, and more specifically to a soft transfer of such connection.

The LEVEL of TECHNOLOGY

Soft transfer service is the sequence of operations by which in the communication system, multiple access, code division multiple access (CDMA) one mobile station (MS) may communicate with two or more sectors and/or two or more cells, essentially simultaneously. Typically, the sequence of operations occurs during the transition of the MS from one cell or sector on the other. Standard TIA/EIA/IS-2001.3-B for CDMA system, published by the Association of communications industry (TIA) from Arlington, Virginia, describes how it can be implemented in a soft transfer. The standard included in the materials of the present application by reference.

The CDMA system typically contains a number of base station controllers (BSC), which supports the communication with the mobile communication switching interface "And". Each BSC is typically attached in the geographical configuration point-to-point connection to a certain number of base transceiver stations (BTS), BSC and BTS communicate via the interface Abis" Abis-sessions. Separate BSC controls the action BT, to which it is attached, and is used by BTS to actions such as the establishment and completion of a telephone call, and for administrative tasks. BTS, in turn, communicates over the air with MS through the ether interface CDMA. In addition, the BSC can communicate with each other through the interface A3/A7. Each interface corresponds to a signaling Protocol known in the art. For example, the interface A3/A7 described in the above TIA, the Abis interface is described in TIA/EIA-828, published TIA, which is included in the materials of the present application by reference.

Soft transfer occurs when the MS simultaneously communicates with two or more BTS. BTS can be connected to the same BSC and/or different BSC. In systems known in the art, if the BTS bound to the same BSC, the interfaces include essential CDMA interface and Abis interface. If BTS is bound to two or more BSC, communication uses three interfaces: essential CDMA interface, Abis interface and the interface A3/A7 between the BSC.

The INVENTION

In variants of the invention, the base station controllers (BSC) system multiple access code division multiple access (CDMA) associated with base transceiver stations (BTS) system through a network, usually the network with packet switching, operating under a CR is a Protocol such as the Protocol of the Internet. Each BTS is able, therefore, to communicate through multiple lines of communication with many BSC and each BSC is able to communicate through multiple lines of communication with many BTS.

Each BTS is attached to a specific BSC, usually on a geographical basis. Each BSC supports the communication line control channel with its attached BTS via the network. The communication line control channel enable BSC to manage individual tasks, such as establishing a telephone call, for a BTS to which it is attached.

In addition to the communication line control channel from the BSC to which it is attached, this BTS can also use line to communicate directly with other BSC during the soft transfer service. This kind of direct communication is at odds with the model of transmission service used in systems known in the art, in which each BTS communicates only with the BSC to which it is attached. In particular, the BSC can open communications with the BTS, which is attached to another BSC, but have a service area transmission that overlap the service area of the BTS, attached to this BSC. (These BTS in the materials of the present application are called adjacent BTS.) As a result, the adjacent BTS is able to perform soft the e-transfer service with attached BTS via communication only with this BSC. This model is at odds with handovers between BSC in systems known in the art, which should be involved both BSC. The model thus allows for more efficient, reliable, soft handovers and also reduces the cost of hardware in comparison with the systems of transmission service between the BSC.

In the first type of soft transmission maintenance mobile station (MS), which conducts a phone call through the first BTS attached to a BSC designated in the materials of this application reference BSC (BSC binding), receives the pilot signal from the second BTS, adjacent the first BTS. The second BTS connected to BSC designated in the materials of the present application, the target BSC, other than BSC binding. The MS sends a notification of reception of the pilot signal in BSC binding. BSC binding, in turn, sends a start signal to the second BTS, which instructs the second BTS to route traffic phone call with MS with the second BTS to BSC binding. BSC binding, thus, receives signals from the traffic of the telephone call to the upward communication line between two adjacent BTS, despite the fact that the second BTS is connected to another BSC. BSC binding processes signals traffic phone call uplink communication, which she takes to find the optimal signal upward bound is I. Similarly, traffic signals telephone call downlink is sent from BSC binding to two adjacent BTS; MS receives the transmitted signals from the BTS and processes the transmitted signals, which it takes to find the optimal signal downlink.

Essentially similar sequence of operations can be applied in the second type of soft transfer service between two BTS connected to the same BSC, the difference between the two types is that in the second type of soft transfer service is not required to perform any forwarding signals. The use of a single Protocol for both types of soft transfer service improves network efficiency and eliminates the need for the traffic of a phone call between the BSC in the first type of soft transfer service.

Therefore, according to the variant embodiment of the invention, provided is a method for performing a soft transmission service, including

DETAILED DESCRIPTION of embodiments

"Mobile station" refers to a device that provides the user voice and/or data communication. The mobile station can be join is changed to a computing device, such as a portable computer or desktop computer, or it may be a separate device such as a personal digital assistant. The mobile station may also be called an access terminal, a subscriber's point, the subscriber node, a mobile station, wireless device, mobile phone, remote station, remote terminal, user terminal, user agent or subscriber equipment. A subscriber can be a cellular phone, PCS phone (personal communication system), cordless telephone, phone session initiation Protocol (SIP), the station of the wireless subscriber loop (WLL), a personal digital assistant (PDA), a handheld device having wireless connection, or other processing device connected to the radio modem.

The combination of a base transceiver station (BTS) and base station controller (BSC) may also be called "access point", which indicates to the device in the access network that supports communication through the ether interface, one or more sectors, with terminal access or other access points. The access point acts as a router between the access terminal and the remaining part of the access network, which may include an IP network, by converting the received AC is the moat essential interface in IP packets. The access point also coordinate the management of attributes for the radio interface.

Further reference is made to Fig. 1, which is a schematic illustration of a cellular system 10, multiple access, code division multiple access (CDMA) according to a variant implementation of the present invention. The CDMA system is used for the purposes of illustration, as it is expected that embodiments of the invention can be used in systems using different modulation schemes. For example, can also be used schemes broadband multiple access code division multiplexing (WCDMA), multiple access frequency division multiple access (FDMA), multiple access with time division multiplexing (TDMA) or multiple access orthogonal frequency division channels.

The first controller 20 of base stations (BSC1) attached to the first set as a whole is similar to the base transceiver stations (BTS) 14B, 14C, .... the Second BSC 50 (BSC2) attached to the second set as a whole is similar to the BTS 34A, .... For the sake of clarity, only BTS 14B and BTS 14C of the first set and only BTS 34A of the second set shown in Fig. 1. Each BSC is responsible for special tasks, such as setting up and completion of a telephone call, for each of its attached BTS. Each BSC is also responsible for the administration of their p is soedinennyh BTS. Joining typically assigned on a geographical basis, so, as an example, Fig. 1 shows BSC1 as having a geographic service area (GCA), which includes BTS 14B and BTS 14C, and shows BSC2 as having GCA, which includes BTS 34A. Properties, associative associated with connections, described in more detail below. BSC communication with the switching center mobile communications (MSC) 22.

In embodiments of the invention the elements of the system 10 containing MSC, BSC and BTS included in the network 16, which provides each of these elements is the ability to establish lines of communication with other elements of the system. Logical connections 21, typically implemented by land line and/or radio-relay communication lines between the network elements used to form the network 16. Examples of separate logical connections formed between the network elements, described in more detail below. Below, as an example, the network 16 assumes a network with packet switching Protocol of the Internet (IP). As described in more detail below, the connection between the elements of the IP network uses one of two transport protocols: the Protocol is connectionless, the materials of this proposal, the prospective transfer Protocol user datagram (UDP), or the Protocol setting on the panorama connection in materials of this application estimated by the transmission control Protocol (TCP). It will be understood, however, that embodiments of the present invention is not limited to working with a separate network type or different type of Protocol and that, essentially, any suitable network and/or Protocol that provide the capability based on numerous connection lines between elements of the system can be used for communication between the MSC, BSC and BTS.

Each BTS has a respective geographic area of the transmission, while the mobile station in the transmission area is able to communicate with the BTS. Zone transfer BTS system 10 schematically illustrated in Fig. 1 and identified by the suffix R. Thus, the area of the BTS transmission 14B is an area 14BR. The system 10 works by configuring a geographic area of the BTS transmission overlapping or adjacent. In the system 10 of the mobile station (MS) 12 is able to communicate over the air with BTS according to, among other things, the zone or zones of the transmission, in which the mobile station is physically located.

Interface, such as the Abis interface between BSC1 and BTS 14B, 14C,..., is used to establish a secure logical connection between the BSC and the BTS, and the connection using the Abis interface, indicated by the session Abis. In other types of communication systems of different interfaces can be used in ka is este logical connection between such subsystems infrastructure. To establish sessions Abis, BSC1 contains the server 17 Abis, and each BTS 14B, 14C contains the client 18 Abis. Similarly BSC2 establishes a reliable logical connection with their BTS via the Abis interface, BSC2 contains the server 17 Abis, and each BTS 34A, ... contains the client 18 Abis. Each server Abis waits for a request from a client Abis, in order to establish the connection. Connections formed using the Abis interface are TCP/IP connections.

In other embodiments of the invention, the data of the telephone call transmission between BSC and BTS may include voice frames, i.e. frames of the traffic of the main channel (FCH), and/or data frames, i.e. frames of the auxiliary traffic channel (SCH). In addition, the data call may also contain information for other channels, such as channels search call and the pilot signal, operating in the network 10. As described in more detail below, the data call is transferred between BSC and BTS in the form of UDP packets.

Returning to the connection described above, in order to perform their duties regarding their attached BTS, each BSC opens the corresponding lines of communication on the control channel with these BTS through their sessions Abis. Each BSC uses their lines of communication on the control channel for sending commands and information related duties. The obligation is nosti include securing resources for BTS and MS during the initial phone call and deallocation of resources during completion.

In the system 10 there are two types of soft transmission service, both occurring when the MS 12 is a region containing a zone transfer from more than one BTS. The first type of soft transfer of care occurs when the MS 12 is in an area where there are numerous areas of transmission from the BTS, which do not have the same Director BSC; such a region is a region a in Fig. 1. The second type of soft transfer of care occurs when the MS is in an area where there are numerous areas of transmission from the BTS, which have the same BSC as a controller; the region is an example of such a field.

Fig. 2 is a block diagram 100 of a sequence of operations of the method showing the steps that are executed when you perform a soft handovers in the system 10, Fig. 3 illustrates the sequence of signals generated by the first type of soft transfer service, and Fig. 4 illustrates the sequence of signals generated by the second type of soft transfer service, according to a variant implementation of the present invention.

In the first step 102 of flowchart 100, the sequence of how each BSC sets the respective sessions Abis with their attached BTS, and then sets a corresponding communication line control attached to BTS pic what edstam sessions Abis. It will be clear that the sessions Abis and the communication line control mounted on the stage 102, use packets and/or data transmitted according to the protocols used by the network 16.

In the second stage 103 each BSC establishes sessions with Abis BTS, adjacent its attached BTS. In the present description of the invention and the claims related given BTS BTS assumes one of those who are able to perform a soft handover service with the given BTS, but these two BTS is not connected to the same BSC. Further examples to clarify concepts related BTS use the schematic area of the transmission shown in Fig. 1. In the first example, BTS 14B is able to perform a soft transfer service only with BTS 14C, as the transmission area BTS 14B overlaps only area BTS 14C. BTS 14B, thus, does not have any neighboring BTS. In the second example, BTS 14C is able to perform a soft transfer service from BTS 34A (like BTS 14B)as zone transfer these two BTS BTS 14C and 34A overlap; in this case, BTS BTS 14C and 34A are adjacent BTS, because they are controlled by a different BSC.

Communication lines installed on the stages 102 and 103 illustrated in Fig. 1, 3 and 4. BSC1 sets the communication line control with BTS 14C and BTS 14B through sessions Abis with these BTS. BSC2 sets the communication line control with BTS 34A through respective session Abis. In addition BSC1 establishes a session with Abis BTS 34A. For clarity, other sessions Abis, which can be installed on the stages 102 and 103, not shown in Fig. 1, 3, or 4; this line includes the session Abis established between BSC2 and BTS 14C.

In the third stage 104 a phone call is established between the MS 12 and one of the BTS, as an example, which is intended BTS 14C, also indicated in the materials of the present application, the source BTS. A phone call contains signals as uplink communication and downlink between 12 MS and BTS 14C, and the MS 12 is able to install a phone call to receive the pilot signal from the BTS 14C. The signals used during the step 104, schematically shown in Fig. 3 and 4. When establishing a telephone call, it is assumed that no conditions are applied soft transmission service that the MS 12 is only in the service area of the BTS 14C. So, during a step 104, the source BTS 14C and BSC1 indicated in the materials of this application BSC binding, use their line management to prepare resources for a telephone call.

Once a phone call has been set, the traffic uplink communication and downlink for a telephone call is transmitted between the BTS 14C and BSC binding using UDP packets.

In the fourth stage 106 MS 12 is moved to the area in which the conditions are applied soft transfer of appropriate sieves the purpose, where MS is the exchange area more than one BTS. As stated above, there are two types of soft transfer service. When both types of 12 MS becomes aware of the presence in the field, where conditions are applied soft transfer service, taking the pilot signal from the BTS, other than the original BTS.

Depending on the type of situation padded transfer service is one of the two branches is observed by the flowchart 100 of a sequence of operations. When the first type of transmission service complied branch 116 to step 108. The second type is observed branch 118 to step 112.

On the branches 116 according to Fig. 3, at step 108, the MS 12 sends a notification to the BSC binding, that is, BSC1, serves as an indication that she received pilot signal from the BTS 34A. The notification is sent via a UDP packet with BTS 14C sent to BSC binding. It will be clear that the notification is sent, serves as notification to the BSC binding that the MS 12 has moved in terms of the first type soft transfer service, as BSC1 do not control the BTS 34A.

In response to receiving the notification, at step 110, BSC1 binding sends a triggering signal for the transfer of a phone call on BTS 34A. The triggering signal for the transfer of the telephone call is transmitted via a session Abis between BSC1 and BTS 34A mounted on the stage 103.

At step 112, for receiving the start signal, the BTS 34A sends traffic call is coming down the line with the MS 12 in BSC binding BSC1, instead of it managing BSC, BSC2. Traffic phone call uplink communication is transmitted using UDP packets sent to BSC binding. During step 112 BSC1 binding continues to receive traffic phone call uplink communication via BTS 14C in the form of UDP packets.

The start signal also induces BSC1 binding to send traffic phone call downlink to the MS 12 to both BTS BTS 14C and 34A using UDP packets directed to both BTS. These two both BTS transmit the downlink, with the same traffic call to MS 12.

At the final stage 114 BSC binding, BSC1, uses UDP packets uplink communication received from the BTS, to produce the optimal signal uplink communication. Optimal signal uplink communication typically is a frame that contains less noise than any of the transmitted signals, separately taken BTS, as is known in the art. BSC binding then sends the optimal signal uplink connection to the MSC 22.

Similarly at step 114 MS 12 generates the optimal signal downlink of the two sets of transmitted signals, which she accepts with a separate BTS.

If the branch 118 flowchart of the operational sequence of the method according to Fig. 4, steps 108 and 110 are not met, so the AK BTS, controlling the second type of soft transmission service, both controlled by the same BSC BSC1 binding. Thus, step 106 is followed by step 112, on which BTS 14B automatically sends traffic to a phone call from 12 in BSC binding, BSC1, as BSC1 manages BTS 14B (as BTS 14C).

Although the above description indicates the signals containing voice and data packets transmitted during the soft transfer service, it will be understood that essentially the same sequence of operations can be used for other signals such as pilot signals that can be transmitted during a soft transfer service.

Will be taken into account that when the sequence of operations of the first type soft transfer service described above, any traffic phone call is not transferred between BSC1 and BSC2, as the entire traffic of the telephone call is directed from the participating BTS on a single BSC binding, in the example above, BSC1. This is in contradiction to the systems of the prior art, in which the traffic of a phone call in the situation of the first type soft transfer service is transferred between BSC, typically through an interface A3/A7.

Thus, it will be considered that the embodiments of described above are given as examples is a and that the invention is not limited to, what has been shown and described in detail above.

SUBSTANCE: invention refers to data transmission in wireless communication system with multiple-key access. Wireless communication terminal scans pilot signals transmitted by sectors in wireless communication system, measures scanned pilot signals, selects serving sector (e.g. sector providing the strongest reception) and identifies nonservicing sectors which can receive strong noise from this terminal. Servicing sector allocates terminal sub-band (sub-bands) which can be used by servicing sector and cannot be used by nonservicing sectors. Terminal transmits data symbols to allocated sub-bands to servicing and nonservicing sectors. These sectors process return communication line transmission from terminal and receive symbols of relaxed solution which represent transmitted data estimations. Symbols of relaxed solution can be combined from common sectors and then decoded to receive decoded packages. Sectors can decode symbols of relaxed solution independently, and decoded packages of these sectors can be combined to receive resultant decoded packages for terminal.

EFFECT: development of relaxed service forwarding for return communication line with restrictive reuse.
