The embodiment of the present invention additionally provides corresponding Apparatus and system.The embodiment of the present invention additionally provides corresponding device And system.Below it is described in detail.

Packet data network gateway (PGW, Packet Data Network Gateway), gateway (SGW, Serving Gateway), mobile management entity (MME, Mobility Management Entity).

Refering to Fig. 1, from the perspective of packet data network gateway, the trunking communication that the embodiment of the present invention provides An embodiment of method include:

101, packet data network gateway sets up the shared biography of first from cluster server to packet data network gateway Defeated passage.

PGW also includes terminal or the shifting receiving signing trunking communication group before receiving the data that server issues The request adding trunking communication group that dynamic management entity MME triggers；Lead to according to the addition cluster received The request of letter group, sets up from cluster server to PGW for adding the colony terminal of trunking communication group Sharing transmission channel, the terminal of signing trunking communication group is referred to as colony terminal after adding trunking communication group；

Can also be to receive the request setting up shared transmission channel that cluster server triggers；Send and set up altogether Enjoy the response message of transmission channel to cluster server, for add the colony terminal of trunking communication group set up from Cluster server is to the shared transmission channel of PGW；The embodiment of the present invention claims from cluster server to PGW Shared transmission channel be first to share transmission channel.

The more important thing is, before receiving data, the shared transmission will set up from PGW to SGW by SGW is led to Road, MME sets up shared transmission channel from SGW to base station, the embodiment of the present invention claims from PGW to The shared transmission channel of SGW is second to share transmission channel, claims the shared transmission channel from SGW to base station It is the 3rd to share transmission channel；

Base station is that all of colony terminal under same community distributes one identical to eat dishes without rice or wine to share transmission logical Road；May there be a lot of communities base station under covering, then all of colony terminal of each community corresponds to one Individual eating dishes without rice or wine shares transmission channel；Base station for the convenience described, if not particularly indicating, described in this patent Lower colony terminal each means all colony terminals of a community under base station, claims from base in the embodiment of the present invention The shared transmission channel of community, colony terminal place of standing is four to share transmission channel.

After being built such that the shared transmission channel from cluster server to colony terminal, cluster server cluster Data distributing is first shared transmission channel to first by server, by first share transmission channel, second share Transmission channel, the 3rd share transmission channel and the 4th and share transmission channel and issue data to colony terminal.

102, described packet data network gateway from described first share transmission channel receive cluster server issue Data, the described data received are shared transmission channel by second by described packet data network gateway, the Three share transmission channel and the 4th shares transmission channel and is sent to colony terminal, so that all colony terminals connect The common road of the shared transmission channel that the same data received are set up between cluster server to colony terminal Only transmit once on footpath.

PGW shares after transmission channel receives data from first, by between PGW and gateway SGW Second share transmission channel and send the data to SGW, SGW and can have one, it is possibility to have multiple, If there being multiple SGW, then at PGW, identical data are shared transmission by each second respectively logical Road is sent to each SGW, and after data are sent to SGW, SGW shares by the 3rd of SGW to base station the and passes Defeated passage sends the data to base station, base station again by base station and community, colony terminal place the 4th share Transmission channel sends the data to colony terminal, and this detailed process see Fig. 2 and understands.

From the point of view of the angle of colony terminal, between described cluster server to the terminal of addition trunking communication group Set up shared transmission channel co-route particularly as follows:

When described colony terminal is under multiple base stations of multiple SGW and the covering of multiple cell, take from cluster Business device to the co-route that shared transmission channel is all of colony terminal of PGW,

For the multiple colony terminals under same SGW, then the shared transmission channel of PGW to described SGW For the co-route of all of colony terminal under described same SGW,

For the multiple colony terminals under same base station, then SGW to the shared transmission channel of this base station is The co-route of all of colony terminal under this base station,

Multiple colony terminals under same MPS process in same base station, then what base station was distributed eats dishes without rice or wine altogether Enjoy the co-route that transmission channel is all of colony terminal under same community.

Co-route is only set up once, when setting up shared transmission channel, it is intended to the shared transmission of foundation is led to Road in the presence of, avoid the need for re-establishing.

Alternatively, on the basis of above-described embodiment, when the colony terminal of described addition trunking communication group moves Time dynamic, update from cluster server to the shared transmission channel of the colony terminal of described movement.

The concrete operations updating transmission channel are determined on a case-by-case basis, such as:

When described colony terminal moves to another community of former base station, if former base station is described collection after moving The community at group terminal place has been set up free mouth and has been shared transmission channel, then use this sharing channel, otherwise this base Zhan Weici community is set up and is eated dishes without rice or wine to share transmission channel；

When another base station under described colony terminal moves to same SGW, if this base station is described The community at colony terminal place has had built up eats dishes without rice or wine to share transmission channel, then use this sharing channel, otherwise This base station is that shared transmission channel of eating dishes without rice or wine is set up in the community at described colony terminal place；

When described colony terminal moves to another SGW, if this SGW Yu PGW has set up shares biography Defeated passage, then use this sharing channel, otherwise sets up the shared transmission channel from PGW to this SGW.

When setting up the shared transmission channel from SGW to base station, then use this sharing channel, otherwise build Found the SGW shared transmission channel to this base station,

When setting up the shared transmission channel of eating dishes without rice or wine having from base station to community, colony terminal place, then this is used to share Passage, otherwise this base station be this colony terminal place community set up share air interface transmission passage.

The method that the embodiment of the present invention provides, under the colony terminal under a base station moves to another base station After, the transmission channel set up under original base station for this terminal can be deleted, to save transfer resource, as In Fig. 2, terminal drawn by dotted line represents when not having colony terminal under this base station, i.e. original under this base station institute There is colony terminal to be moved into other base station, delete from base station to there is no eating dishes without rice or wine altogether of colony terminal Enjoy transmission channel, it is assumed that terminal moves to the position in figure drawn by heavy black, need to set up being total to this terminal Enjoy transmission channel, i.e. this base station the most establishes this for other colony terminal of same community and shares transmission Passage, then this terminal directly uses the cluster set up before this to share transmission channel, if this terminal is this base station Unique colony terminal of next community, then base station needs to set up the shared transmission channel of this terminal, this Sample has ensured that colony terminal still can receive, after moving, the data that cluster server issues.Ensure that terminal Mobility.

In the embodiment of the present invention, from the perspective of MME, MME sets up the 3rd from SGW to base station altogether Enjoying transmission channel, the described 3rd shares transmission channel for the data that transmission forwards from SGW, described data Being that cluster server issues, and share transmission channel by first, second shares transmission channel, and the 3rd altogether Enjoy transmission channel and the 4th to share transmission channel and pass to colony terminal, so that all colony terminals receive The co-route of shared transmission channel set up between cluster server to colony terminal of same data on Only transmission is once；Wherein, described first to share transmission channel be the cluster server shared transmission to PGW Passage；Described second shares the shared transmission channel that transmission channel is PGW to SGW；Described 4th shares Transmission channel is the shared transmission channel that community, colony terminal place is arrived in base station.

In the embodiment of the present invention, from the perspective of SGW, SGW sets up second from PGW to SGW altogether Enjoy transmission channel；Described SGW shares transmission channel from described second and receives the data that PGW forwards, described Data are that cluster server issues, and share transmission channel pass to PGW by first；Described SGW By the 3rd, the described data received are shared transmission channel and the 4th share transmission channel and be sent to cluster Terminal, so that the same data that all colony terminals receive are built between cluster server to colony terminal Only transmit once on the co-route of vertical shared transmission channel；Wherein, described first shares transmission channel and is Cluster server is to the shared transmission channel of PGW；Described 3rd to share transmission channel be that SGW arrives base station Share transmission channel；Described 4th to share transmission channel be the shared transmission that community, colony terminal place is arrived in base station Passage.

In the embodiment of the present invention, from the perspective of base station, base station is set up little to colony terminal place from base station The 4th of district shares transmission channel, and it is logical that all colony terminals in each community share one article of the 4th shared transmission Road；Described base station is shared transmission channel from the 3rd and is received the data that SGW forwards, and described data are cluster clothes Business device issues, and shares transmission channel by first, and second shares transmission channel, and the 3rd shares transmission leads to Road passes to base station；Described base station will receive data and share transmission channel by the 4th and be sent to cluster eventually End, so that the same data that all colony terminals receive are set up between cluster server to colony terminal Shared transmission channel co-route on only transmission is once；Wherein, described first shares transmission channel for collection Group's server is to the shared transmission channel of PGW；Described second to share transmission channel be being total to of PGW to SGW Enjoy transmission channel；Described 4th share transmission channel be base station arrive community, colony terminal place shared transmission lead to Road.

In the embodiment of the present invention, from the perspective of colony terminal, colony terminal shares transmission channel from the 4th Receiving the data that base station forwards, described data are that cluster server issues, and it is logical to share transmission by first Road, second shares transmission channel, and the 3rd shares transmission channel and the 4th shares transmission channel and pass to cluster eventually End, what the same data that all colony terminals receive were set up between cluster server to colony terminal shares Only transmit once on the co-route of transmission channel；Wherein, described first to share transmission channel be cluster service Device is to the shared transmission channel of packet data network gateway；Described second to share transmission channel be Packet Data Network's net Close the shared transmission channel of gateway；Described 3rd to share transmission channel be gateway being total to base station Enjoy transmission channel；Described 4th share transmission channel be base station arrive community, colony terminal place shared transmission lead to Road.

Described cluster server to the shared transmission channel set up between colony terminal co-route particularly as follows:

When described colony terminal is under multiple base stations of multiple gateways and the covering of multiple cell, first altogether Enjoy the co-route that transmission channel is all of colony terminal；

For the multiple colony terminals under same gateway, then second to share transmission channel be described same The co-route of all of colony terminal under individual gateway；

For the multiple colony terminals under same base station, then the 3rd to share transmission channel be the institute under this base station The co-route of some colony terminals；

For the multiple colony terminals under MPS process same in same base station, then the 4th shared transmission is logical Road is the co-route of all of colony terminal under same community.

Actually from the perspective of MME, SGW and base station, the process of data transmission is identical, only During setting up transmission channel, they each role different.

Process of setting up about the shared transmission channel set up from cluster server to colony terminal see down The process in face 3～Fig. 7 understands.

Refering to Fig. 3, another embodiment of the method for the trunking communication that the present invention provides includes:

201, terminal sets up default bearer.

Terminal sets up a grouped data to particular access point title (APN, Access Point Name) Network (PDN, Packet Data Network) connects, and this APN is the specific APN of trunking communication institute, In the process, default bearer (Default Bearer) is set up, and after step 201, system may be also simultaneously A single dedicated bearer (Dedicated Bearer) is set up for terminal；

202, mobile management entity triggering terminal adds the trunking communication group of described terminal unit contractual.

The end that MME transmits according to local subscribed services (HSS, Home Subscriber Server) The subscription data of end determines which trunking communication group of terminal unit contractual, triggers the most voluntarily and adds these trunking communications Group, i.e. MME send to S-GW and add trunking communication group of instructions (TGJC, Trunk Group Join Command) message, described TGJC message carries the trunking communication group identification of described trunking communication group, Such as IP multicast address, then SGW sends TGJC message to PGW.

203, group's insertion authority.

After PGW receives the terminal addition TGJC message that SGW sends, send TGJC message and take to cluster Business device；PGW and cluster server carry out group's insertion authority of terminal, and PGW provides to cluster server The mark of terminal, such as international mobile subscriber identity (IMSI, International Mobile Subscriber Identification Number) and mobile terminal ISDN (MSISDN, Mobile Subscriber International ISDN/PSTN number) mark；Cluster server is according to the mark of user and cluster thereof User contracting data on server, or, the mark of the terminal that cluster server provides according to PGW from Get the subscription data of user on HSS/HLR, or on cluster server, storage has the signing number of cluster service According to, decide whether to allow this terminal to use cluster service；When cluster server by the certification of terminal with award Quan Hou, terminal adds the trunking communication group of described trunking communication group identification, can will add trunking communication The terminal of group is referred to as colony terminal, just establishes shared transmission channel between cluster server and PGW； Same reason, if the shared transmission channel the most established between cluster server and PGW, then weighs By shared transmission channel before without re-establishing.

204, PGW sends the first trunking communication group bearing activation request message to SGW, and SGW sends out Send the second trunking communication group bearing activation request message to MME.

Described first and second trunking communication group bearing activation request message carry described trunking communication group Mark and the APN specified；

205, MME sends the 3rd trunking communication group bearing activation request message by base station to terminal. MME marks according to described trunking communication group before sending the 3rd trunking communication group bearing activation request message The APN known and specify judges that base station has set up the first downlink tunnel port-mark and IP ground the most Location；If having set up the first downlink tunnel port-mark and IP address, sending the 3rd trunking communication group During bearing activation request message, send instruction base station simultaneously and use the first downlink tunnel port-mark set up And the instruction information of IP address；If not setting up the first downlink tunnel port-mark and IP address, sending During the 3rd trunking communication group bearing activation request message, send simultaneously and set up group's RAB request To base station, base station is made to set up the first downlink tunnel port-mark and IP address；First downlink tunnel port mark Know and S1-U interface that IP address refers to distribute base station descending GTP-U (GTP user plane, GTP, GPRS Tunnelling Protocol, General Packet Radio Service tunnel protocol) TEID (Tunnel End Point Identifier, tunnel port-mark) and IP address.

Whether the base station no matter MME judges sets up the first downlink tunnel port-mark and IP address, base station 3rd trunking communication group bearing activation request message is sent to terminal, and being total to of eating dishes without rice or wine of distribution one simultaneously Enjoy transmission channel to terminal, thus set up the shared transmission channel from base station to terminal.Be similar to SGW with Shared transmission channel between base station, between all terminals in same community and this base station under base station also It is to be used in conjunction with one to eat dishes without rice or wine to share transmission channel.

206, MME receives group's RAB response message that base station sends.

If base station is when receiving the 3rd trunking communication group bearing activation request message in step 205, also connect Have received MME transmission sets up group's RAB request, then the first downlink tunnel end is distributed in base station Mouthful mark and IP address, and send group's RAB response message to MME, described group is wireless Access bearer response message carries the first downlink tunnel port-mark and the IP address of foundation；

If base station is when receiving the 3rd trunking communication group bearing activation request message, receive use built The first vertical downlink tunnel port-mark and the instruction information of IP address, then the parameter that reply use has been set up Response message is to MME.

207, MME receives the first trunking communication group bearing activation response message that terminal sends.

208, MME sends the second trunking communication group bearing activation response message to SGW, SGW transmission 3rd trunking communication group bearing activation response message is to PGW.

MME sends the second trunking communication group bearing activation response message to SGW, and described second cluster leads to Letter group bearing activation response message carries trunking communication group identification, it is intended that APN and first Downlink tunnel port-mark and IP address, set up the shared transmission channel from SGW to base station；

SGW distributes before determining with the APN specified according to trunking communication group identification the most One the second downlink tunnel port-mark and IP address, if unallocated, SGW distributes the second downlink tunnel end Mouthful mark and IP address, and described second downlink tunnel port-mark and IP address carried the by SGW Three trunking communication group bearing activation response messages are sent to PGW, set up sharing from PGW to SGW Transmission channel；If distributing, also the second downlink tunnel port-mark and IP address are carried at the 3rd cluster Communication group bearing activation response message is sent to PGW, sets up the shared transmission from PGW to SGW and lead to Road.Second downlink tunnel port-mark and IP address refer to the descending of S5 or the S8 interface that SGW distributes GTP-U TEID and IP address thereof.
