Embodiment.

One, the enforcement of transmission of messages passage (signalling path):

1), the enforcement that the transmission of messages passage is set up between UE and grouping access unit:

The employed passage of transmission of messages between UE and grouping access unit, can implement by following dual mode:

Mode one: utilize the IP carrying of gruping insertion network (to comprise and to utilize UE when packet access network adheres to that packet access network is the default IP carrying that UE sets up; The IP carrying of perhaps in packet access network, setting up separately, the carrying that utilizes PDP (Packet Data Protocol, packet data protocol) context activation process to set up such as dedicated bearer and the GPRS of SAE).And external interface (such as Gi or the SGi) interface that utilizes grouped data network gateway to provide, constituting the transmission of messages passage between UE and grouping access unit, the essential characteristic of this transmission of messages passage is that passage is through dividing the winding data network gateway.Transmission of messages passage between UE and grouping access unit can adopt TCP or host-host protocols such as UDP or SCTP.

Mode two: utilize in UE and the gruping insertion network original transmission of messages passage between Mobility Management Entity, and the interface between newly-increased Mobility Management Entity and grouping access unit, constitute from UE and the transmission of messages passage that divides into groups between access unit.The essential characteristic of this transmission of messages passage is that passage is through Mobility Management Entity.

2), the enforcement that the transmission of messages passage is set up between grouping access unit and MSC:

The employed passage of transmission of messages between grouping access unit and MSC, can adopt Simulation with I u-CS or the wireless access network control interface of networks such as simulation A interface or CDMA2000 or the mode that other form interface provides, if MSC closes with the grouping access unit and establishes, then described passage is arranged in internal interface, in this case, the execution mode of passage is not limited to above form.

Two, the enforcement of message route:

UE, grouping access unit and MSC need pass-along message when carrying out business, the route of interaction message process can be implemented as follows:

1, the message route between UE and grouping access unit.

1) UE is to the route of the message of grouping access unit transmission

Grouped data network gateway in UE or the gruping insertion network or Mobility Management Entity can comprise the first grouping access unit determination module, the targeted packets access unit of the message that is used for determining that UE is sent.

Concrete, UE can have three kinds of modes to the route that the grouping access unit sends message:

A, in the message that UE sends, carry the address information of grouping access unit, this information can be obtained by grouped data network gateway or the Mobility Management Entity of UE from packet access network (such as can be by UE when being attached to gruping insertion network, in adhering to response message, carry this information by Mobility Management Entity and give UE, this information can come from Mobility Management Entity itself, or comes from grouped data network gateway; Perhaps, when setting up carrying, by grouped data network gateway this information is set up response message by carrying and offer Mobility Management Entity, and then offer UE) by Mobility Management Entity; Or UE obtains configuration information by the DHCPv6 mode from network, and the address information of the grouping access unit Dynamic Host Configuration Protocol server in network in advance is configured; Or in UE (terminal or subscriber card), disposing this information, packet data gateway in the packet access network or Mobility Management Entity will be routed to the grouping access unit from the message of UE according to this address information.

B when this message is sent to grouped data network gateway (as PDN GW or GGSN), determines the grouping access unit by grouped data network gateway, routes messages to this grouping access unit.Grouped data network gateway can be pre-configured itself and the corresponding relation of grouping access unit, determine the targeted packets access unit according to this relation.If packet data gateway has connected a plurality of grouping access units, grouped data network gateway can be determined the targeted packets access unit according to positional information or the subscriber identity information of UE, or determine the targeted packets access unit, or determine a targeted packets access unit arbitrarily from the uniform angle of loading.Further, handle in order to make same user's subsequent message mail to identical MSC, the grouping access unit can adopt record to determine that result's method reaches this purpose, and this processing can be finished when user position update, and when calling out the result of service recorder.

C, this message is sent to Mobility Management Entity, determines the grouping access unit by Mobility Management Entity, routes messages to this grouping access unit.Mobility Management Entity can be pre-configured itself and the corresponding relation of grouping access unit, determine the targeted packets access unit according to this relation.If Mobility Management Entity has connected a plurality of grouping access units, Mobility Management Entity can be determined the targeted packets access unit according to positional information or the subscriber identity information of UE, or determine the targeted packets access unit from the uniform angle of loading, or it is single to determine that arbitrarily targeted packets inserts.Further, handle in order to make same user's subsequent message mail to identical MSC, Mobility Management Entity can adopt record to determine that result's method reaches this purpose, and this processing can be finished when user position update, and when calling out the result of service recorder.

2) the grouping access unit sends the route of message to UE.

Can comprise the UE determination module in the grouping access unit, be used for determining object UE address relevant information, carry out the route of message with this.Concrete mode has two:

A: the grouping access unit is routed to UE with message through grouped data network gateway according to the IP address information of UE.

The grouping access unit obtains the IP address of UE and can implement as follows:

The grouping access unit has been received the message from UE earlier, by carry the IP address information of UE in this message, makes the grouping access unit obtain the IP address information of UE.Such as being that the grouping access unit has been received the location update request message from UE, in location update message, contain the address information of UE;

It can also be grouping access unit (such as beep-page message or call setup message of having received from MSC) before having message to mail to UE at UE, obtain the address information of UE from gruping insertion network: the grouping access unit can be inquired about the address information of UE to it according to itself and the configuration relation of packet access network Mobility Management Entity (as MME).This configuration relation can be presented as the corresponding relation of UE user identity or user present position and Mobility Management Entity, and the access unit that divides into groups in this case can obtain the address information of UE to UE corresponding movable management entity; This configuration relation also can be presented as all coupled Mobility Management Entity address informations of grouping access unit record, and in this case, the grouping access unit can obtain the address information of UE to all coupled Mobility Management Entity inquiries.

B: the grouping access unit is determined the address information of UE corresponding movable management entity, routes messages to UE via Mobility Management Entity.Wherein, the grouping access unit can be determined target mobility management entity by the corresponding relation of UE user identity or user present position and Mobility Management Entity, perhaps, the grouping access unit receive earlier one about UE from Mobility Management Entity message, according to the Mobility Management Entity address information in this message, the grouping access unit has write down UE corresponding movable management entity, and the grouping access unit is determined Mobility Management Entity in this way; Mobility Management Entity can be identical with existing mode with message route between UE, such as the route of adhering to response message between UE and Mobility Management Entity.

2, the message route between grouping access unit and MSC.

1), the grouping access unit sends the route of message to MSC.

The grouping access unit can comprise the MSC determination module, is used for determining that the grouping access unit sends the target MSC of message:

Concrete, be one to one or the situation of one-to-many for MSC and grouping access unit, the grouping access unit can be determined unique MSC, by the address information at grouping access unit configuration MSC, the grouping access unit can route messages to MSC;

If a grouping access unit links to each other with one or more MSC, can select a MSC by the grouping access unit is target MSC, selects the method for MSC to be:

The grouping access unit can be pre-configured itself and the corresponding relation of grouping access unit, determine target MSC according to this relation.If the grouping access unit has connected a plurality of target MSC, the grouping access unit can be determined target MSC according to positional information or the subscriber identity information of UE, or determine target MSC from the uniform angle of loading, or definite arbitrarily target MSC, or UE has obtained the address information (method of address information that its method and above-described UE obtain the grouping access unit is identical) of MSC earlier, UE sends the address information that message is carried MSC to the grouping access unit, and the grouping access unit is determined target MSC from this message.Further, handle in order to make user's subsequent message mail to identical MSC, the grouping access unit can adopt record to determine that result's method reaches this purpose, and this processing can be finished when user position update, and when calling out the result of service recorder.

2), MSC sends the route of message to the grouping access unit.

MSC can comprise grouping access unit determination module, is used for the address relevant information of the targeted packets access unit of definite message that MSC sends, and with this route of carrying out message, mode is as follows:

Grouping access unit determination module is determined the address information of targeted packets access unit, to carry out the message route according to the mapping relations of positional information, positional information and the grouping access unit at UE place.

Perhaps, MSC has received the UE related news from the grouping access unit earlier, by carry the address information of grouping access unit in this message, makes MSC obtain the address information of the grouping access unit of UE correspondence.Received such as MSC and location update request message from the grouping access unit in location update message, to have contained the address information of the access unit that divides into groups.Further, when MSC can upgrade in the user position record UE and the corresponding relation of grouping access unit, be used for the follow-up targeted packets access unit of when the grouping access unit sends message, determining.

Three, media negotiation and the enforcement of carrying control.

If (what carry out such as the user is calling class service to need to carry out the medium communication in the business procedure, need set up media channel to carry out the medium communication, if but carry out be short message service then do not need), need this moment UE and network side (grouping access unit and MSC) to carry out media negotiation, and be that call setup service bearer passage transmits to carry out media data.

Its process can be implemented as follows:

Media negotiation and media data transmit.

The bearer path administration module comprises MSC side management submodule, gruping insertion network side management submodule, wherein:

MSC side management submodule distributes or reclaims the bearing resource of local terminal, sets up, revises or discharge the carrying of MSC side;

The carrying of gruping insertion network side management submodule management UE side (UE is between grouped data network gateway).

Further, the bearer path administration module also comprises grouping access unit management submodule, the carrying of management grouping access unit and UE side and MSC side.The situation that this is mainly used in MSC and grouping access unit employing ATM transmission means also can be applicable to the situation that MSC and grouping access unit all adopt the IP transmission means.

May further include the media negotiation unit in the system, be used for carrying out the negotiation of media description information in UE side and MSC side.In the media negotiation unit, can comprise UE side media negotiation module, MSC side media negotiation module, wherein:

UE side media negotiation module is used for UE and sends and from MSC direction receiving media descriptor and hold consultation to the MSC direction;

MSC side media negotiation module is used for MSC and sends and from UE direction receiving media descriptor and hold consultation to the UE direction.

UE side media negotiation module is carried on described media description information in Setup (call setup) message and sends when UE does caller; Do when called at UE, described media description information is carried on call confirmation, ring, connects in one of them the message and send;

MSC side media negotiation module is carried on described media description information call progress, ring, connects in one of them the message and send when UE does caller; Do when called at UE, described media description information is carried in one of them the message of Setup (call setup), Information (information), Notify (notice), Facility (equipment) sends.

The media negotiation unit can also comprise that further grouping access unit media negotiation module is used to divide into groups access unit respectively and carry out the negotiation of media description information between UE and the MSC.

Grouping access unit media negotiation module can also be when receiving that the UE direction contains the message of media description information, media description information in the message is carried on assignment to be finished and sends to MSC in the message, perhaps, utilize the message of former described media description information that media description is sent to MSC.

Grouping access unit media negotiation module is after the carrying modular converter has distributed the carrying identical with the UE side, the corresponding media description information of described carrying is offered UE, after the carrying modular converter had distributed the carrying identical with the MSC side, described grouping access unit media negotiation module offered MSC with the corresponding media description information of described carrying.

Media negotiation unit newly-increased cell in message transmits described media description information, perhaps, media description information and former message is contained in side by side transmits described media description information in the IP packet.Media description information can comprise one of following information or its combination: IP address and port, atm address, code/decode type.

Concrete, during media negotiation, MSC inserts side (grouping access unit and UE) to grouping MSC end media information is provided, and UE provides UE side media information to network side (grouping access unit and MSC), and the grouping access unit also may provide media information to UE and MSC.Described media information will comprise one of following information at least: the coding/decoding information of Media Stream to be set up, UE side, grouping access unit and network side are respectively the beared information (IP address and port, or atm address information) of media delivery distribution, the media transmission protocol information that adopts.

After media negotiation finishes, set up data transmission channel between UE and MSC according to the result of media negotiation, making can media data between UE and MSC.

1), the foundation of MSC side carrying is implemented:

Before grouping access side (grouping access unit and UE) provided MSC end media information, MSC distributed the local terminal bearing resource, obtains the address information (IP address and port, or atm address information) of this bearing resource at MSC.If MSC separates framework (being that MSC is decomposed into MSC server and MGW), then described bearing resource is positioned at MGW (media gateway).The carrying schematic diagram that Fig. 4 distributes for the MSC side is the bearing resource that is distributed shown in No. 4 circles among the figure.

2), the foundation of UE side carrying (the packet data network network (borde gateway) from gruping insertion network is to the carrying UE) is implemented:

At UE after network side (grouping access unit and MSC) provides the media information of UE side, the grouping access unit is initiated UE side loading establishing process to gruping insertion network: the grouping access unit provides UE side carrying descriptor to gruping insertion network, such as the QoS relevant parameter, and IP address and the port information of UE, gruping insertion network is set up the carrying of UE side according to these information.Be not limited to the opportunity of setting up the carrying beginning is after the grouping access unit is received the Assignment Command of MSC.The carrying schematic diagram that Fig. 5 distributes for the UE side is the bearing resource that is distributed shown in No. 1 circle among the figure.

3), the carrying of grouping access unit is set up and is implemented:

Bearer path is set up module can also comprise carrying conversion submodule, distributes the bearing resource identical with the MSC side with the UE side when being used for UE side media bearer with MSC side media bearer Type-Inconsistencies, carries conversion.

Concrete, if MSC provides the carrying of ATM mode, be the carrying of IP mode and the UE side adopts, then carry out the conversion that IP carrying and ATM carry by the grouping access unit.Grouping access unit distributing IP bearing resource and ATM bearing resource, obtain the address information of IP bearing resource and ATM bearing resource, and IP bearing resource address and port information offered UE, ATM bearing resource address information is offered MSC (if MSC separates framework, the ATM beared information of access unit side provides MGW but the ATM Access Link Control Application Protocol will divide into groups).Make that adopting the IP mode to carry out data between UE and grouping access unit transmits, and transmits and adopt the ATM mode to carry out data between grouping access unit and MSC, and by the carrying translation function of grouping access unit both sides is connected.

This mode is applicable to that too MSC provides the situation of the carrying of IP mode.

The carrying schematic diagram that Fig. 6 distributes for the grouping access unit, shown in Fig. 2 number and No. 3 circles, be the distribution bearing resource.

4), the grouping access unit serves as the enforcement that media information transmits the agency:

If what MSC and UE side all adopted is the carrying of IP mode, the grouping access unit will send MSC to from the beared information (IP address and port) of UE side, and will send UE to from the beared information of MSC side, make UE and MSC that media data can directly be mail to the other side without the grouping access unit, Fig. 7 acts on behalf of schematic diagram for the grouping access unit serves as the media information transmission, as shown in the figure: pass through grouping access unit exchange the other side's beared information by UE and MSC, make that the medium between UE and MSC needn't be through the grouping access unit.

5), the enforcement of the transfer mode of media description information:

UE is when doing caller, UE can be attached to media information and offer the grouping access unit in the Setup message, when the grouping access unit adopts the IP mode to carry at MSC, by Setup message or the time UE side media information is being offered MSC to MSC transmission assignment response message, when MSC adopts the ATM mode to carry, is that the address information of the UE ATM carrying of setting up offers MSC (MSC can adopt unification or separation architecture by Access Link Control Application Protocol with gruping insertion network, when adopting separation architecture, described information offers MGW), the grouping access unit is attached to call progress with the media information of network side, ring, connect in one of them the message and offer UE;

UE is doing when called, UE can be attached to Call Confirmed (call confirmation) or ring or connection message with the media information of UE side and pass to described grouping access unit, the grouping access unit carries beared information or offer MSC after carrying beared information in the assignment response message that sends to MSC by call confirmation or ring or connection message, and the grouping access unit is attached to the media information of network side in Setup (call setup) or Information (information) or Notify (notice) or Facility (equipment) message and offers UE.

Concrete, the coding/decoding information in the media information can transmit by original mode between MSC and UE.All the other information (address information is as IP address and port or atm address, coding/decoding information etc.) can be by independent message transmission; Also can adopt mode additional on the message related to calls between original MSC and UE to transmit.

If adopt a kind of mode in back, additional method can be: defining the cell in the message related to calls (such as Setup message), carry in message, also can be arranged side by side as an information and original message, is encapsulated in together in the IP packet.

Dividing into groups access unit when MSC provides media information, two kinds of situations are arranged: first, if what MSC adopted is the carrying of IP mode, the access unit that then divides into groups can offer MSC with UE side media information by above-mentioned Setup message, and the grouping access unit also can offer MSC with beared information when MSC sends the assignment response message; The second, if the MSC employing is the carrying of ATM mode, in this case, can adopt the mode of ALCAP (Access Link Control Application Protocol, Access Link Control Application Protocol) protocol description to finish.

Four, the enforcement of dialogue mechanism:

In message interaction process, carry out the message transmission between UE and grouped element, also need a kind of dialogue mechanism, so that the relevant message of each business is carried out association.

In the enforcement, can only carry out a business simultaneously if limit UE, so can be by being connected with the IP that divides into groups to set up between access unit a pass-along message at UE.This IP connects IP address, the port of available UE, and grouping access unit IP address allocated and port identify.Initiating when professional, the IP address that exchanges the other side by both sides can be established this IP with port information and be connected, and port information can also adopt the mode of default convention, needn't intercourse port information in this case.UE just can utilize this IP to be connected with the grouping access unit, the message of being received and dispatched is associated with business, because a UE divides into groups only have the IP of a pass-along message to be connected between access unit with one, therefore before business did not finish, the message that the UE and the access unit that divides into groups utilize this IP to be connected and received and dispatched all can be relevant with current ongoing business.

If make UE can carry out a plurality of business simultaneously, it is related then to need a kind of dialogue mechanism that UE and grouping access unit are carried out message and each parallel business, can realize the mechanism of dialogue by following dual mode:

A, set up special IP for each business and connect, only transmit the relevant message of a business simultaneously during an IP connects.This IP connects IP address, the port with UE, and grouping access unit IP address allocated and port identify.When making a call, the IP address that exchanges the other side by both sides is established this IP with port information and is connected.Can use TCP/UDP/SCTP (Transmission ControlProtocol/User Datagram Protocol/Stream Control Transmission Protocol, transmission control protocol/User Datagram Protoco (UDP)/SCTP) to connect in the enforcement and realize that IP connects.The message of call hold service and call waiting can be transmitted in an IP is connected with former message related to calls in the enforcement.

B adopts an IP to connect the message of transmitting a plurality of concurrent services.This need identify each professional message, belongs to each professional message thereby distinguish.The method that business is identified can be: initiate business side when initiating business, for sign of this traffic assignments, offer the other side, later in this professional message interaction process, all carry this information in message, both sides just can correspond to message each business.Service identification discharges after calling is finished.After business was finished, this sign can be used in the business of new initiation.

Another embodiment can for: when the other side receives the described sign that the initiator distributes, the other side also is sign of this traffic assignments simultaneously, two signs are represented this business jointly, the identification information that both sides' exchange distributes separately, carry this two signs in the later message interaction process, with this with message and business association.

As: UE makes a call to the grouping access unit, and UE distributes call identification 1, after the grouping access unit is received this sign, distributes call identification 1, and [(UE :) 1, (grouping access unit :) 1] is exactly the sign of this calling so; If another calling of the parallel initiation of UE, then UE distributes 2, grouping access unit 2, and then [(UE :) 2, (grouping access unit :) 2] is the sign of this calling; If UE or grouping access unit make a call to the other side respectively simultaneously, then UE distributes 3, and the sign 3 of grouping access unit has been initiated to call out occupied because of it to UE, so the access unit distribution 4 of dividing into groups, therefore, [(UE :) 3, (grouping access unit :) 4] be the sign of the calling of this UE initiation, in like manner, [(grouping access unit :) 4, (UE :) 3] is the sign of that time calling of grouping access unit initiation.This scheme is applicable to all kinds of business, such as calling out or short message service.

Another embodiment can for: still come allocation identification by the initiator, pass to the other side, in the message interaction process afterwards, message sender be except carrying above-mentioned sign, also carries the call initiator sign, distinguishes different callings with this.

As: UE distributes call identification 1 when the grouping access unit makes a call, pass to the grouping access unit, UE is when the grouping access unit sends the message of this calling or oppositely sends message later on, UE and grouping access unit all carry call identification 1 and " UE initiation " sign, so just can find the calling of message correspondence.If UE initiates the 2nd calling simultaneously, then distribute call identification 2, then available 2 and " UE initiation " identify this new calling, the recipient can with this with message to calling out association.This scheme is applicable to all kinds of business, such as calling out or short message service.

Five, the enforcement of paging processing:

If what the user carried out is call business or short message service, when the user does when called, insert the situation of MSC by circuit domain according to UE, MSC can carry out paging to the user.

And if user UE inserts MSC by gruping insertion network and carries out business, when the user does when called, MSC can not carry out paging to the user.MSC can judge this user by the residing positional information of user and insert by gruping insertion network, or the user carries a sign when upgrading in the position and gives MSC transmitting the user by grouping access unit position updated information, MSC and then make the processing of this user not being carried out paging.Or MSC still carries out paging to the user, after the grouping access unit is received this message, replys page-response message to MSC.

Six, the enforcement of supplementary service:

By the interacting message signalling path of setting up, and the existing supplementary service tenability of MSC, UE can carry out the mutual of supplementary service with MSC, and then identical supplementary service when offering user UE and inserting with circuit domain.Described supplementary service includes but not limited to: caller/and by the demonstration of consecutive numbers sign indicating number and restriction, Call Forwarding (Call Forwarding Unconditional/Call Forwarding on mobile subscriber Not Reachable/Call Forwarding No Reply/divert when busy), Call Deflexion, Call Waiting, calling maintenance, call display transfer, Multi-Way Calling and multi-call service etc.

Seven, the enforcement of short message service:

1), the interacting message signalling path by setting up, and the existing short message tenability of MSC, UE can carry out the mutual of circuit domain short message service with MSC, and then identical short message service when offering the user and inserting by circuit domain.

2), messaging service can also be realized by alternate manner, as: but the processing of MSC holding circuit territory short message service is constant, and UE can adopt SIP IM (Session Initiation Protocol InstantMessage, the session initiation protocol instant message) processing mode, in this case, only need the message of grouping access unit in UE side SIP IM message and the discernible circuit domain short message service of MSC to change mutually, Fig. 8 handles the schematic diagram of short message service for instant message, as shown in the figure, if allow UE and MSC all adopt SIP instant message form, the access unit that then divides into groups does not need to carry out the operation of format conversion.

Eight, the enforcement of call business interacting message:

1), the form of message related to calls;

If allow UE and MSC all adopt circuit domain call to set up message or all adopt SIP (SessionInitiation Protocol, session initiation protocol) session to set up message, the access unit that then divides into groups does not need to carry out the operation of format conversion.

If but the MSC holding circuit territory processing mode of calling out still, and UE adopts the SIP session to set up mode, the access unit that then divides into groups need be changed the call establishment that process and MSC are set up in the SIP session of UE side mutually.

2), charging relevant treatment:

When the user initiates business by gruping insertion network, operator may take different rates to calling, in order to make MSC can perceive this point, MSC can be the position change of being undertaken by gruping insertion network by positional information or the discovery user of UE, and then finds that the user is the calling of initiating by gruping insertion network; MSC can be to find that from grouping access unit this point the user is the calling of initiating by gruping insertion network according to calling also, this can also can carry a sign by UE or grouping access unit and come to show that to MSC the user is the calling of initiating by gruping insertion network by MSC and grouping being connected to dispose and finding between access unit in the message that makes a call.

If the real time billing of adopting, MSC/SSP (Service Switching Point, Service Switching Point) also needs " user is the calling of initiating by gruping insertion network " this information is offered IN service processing capacity SCP (Service Control Point, service control point), MSC/SSP can carry this message and give SCP in IDP (InitialDetection Poin, Initial Detection Point) message.
