The present invention relates to communication technical field, be specifically related to carrying establishing method and relevant apparatus.

Background technology

At present in third generation partner program (3GPP:Third Generation Partnership Project); The notion of long-term evolving network/System Architecture Evolution network (LTE/SAE:Long TermEvolved/System Architecture Evolved) has been proposed; The purpose of LTE provides a kind ofly can reduce time delay, improve user data rate, system capacity improvement and the low network of covering cost; For convenience; The SAE network architecture is simplified, can be divided into 2 parts, as shown in Figure 1:

First: subscriber equipment (UE:User Equipment) 101; Wireless access network (RAN:Radio Access Network) 102; Service universal grouping wireless business supporting node (SGSN:ServingGeneral Packet Radio Service Support Node) 103; Grouped data network gateway (PGW:Packet Data Network Gateway) 104, wherein:

RAN is made up of radio network controller (RNC) and base station (NodeB).RNC is used for distributing and is attached thereto with control or the Radio Resource of relevant NodeB, and main the completion connects foundation and functions such as disconnection, switching, grand branch are gathered also, RRM control.NodeB accomplishes the conversion of data flow, also participates in a part of RRM simultaneously.

The SGSN significant feature is Internet protocol (IP:Intemet Protocol) grouping of transmitting I/O for the travelling carriage of this SGSN coverage (MS).The function that SGSN provides comprises: the route and the forwarding capability of the packet data package in this SGSN area, for all users in this SGSN area provide service, encrypt and authentication functions conversation management functional, mobile management function etc.Wherein, SGSN 103 be 3GPP version 7 and before the SGSN of version, design this SGSN and make the SAE framework can backward compatible Previous System.

PGW is responsible for the user plane anchor point function that UE is linked into Packet Data Network, communicates with the external packet data net, has the function of grouping route and forwarding, and responsible policy, billing enhancement function, based on packet filtering function of each user etc.Simultaneously, PGW links to each other with the IP network of operator.

Second portion: subscriber equipment 101; Wireless access network 105, service universal grouping wireless business supporting node (SGSN) 106, gateway (SGW:Serving Gateway) 107; Grouped data network gateway PGW (Packet Data Network Gateway) 104, wherein:

The user plane context of the last preservation of SGW UE like IP address and the routing iinformation of UE, is carried out functions such as Lawful Interception, grouped data route.

SGSN 106 is SGSN of 3GPP version 8, and this SGSN can directly communicate by letter with SGW.

Existing carrying establishing method all be based on 3GPP version 7 and before the SGSN of version, 3GPP version 7 and before the SGSN of version directly be connected with PGW, existing a kind of carrying establishing method is as shown in Figure 2, comprising:

Step 201, UE send to SGSN and activate packet data protocol (PDP:Packet Data Protocol) context request message; This request message carries bearing identification and service quality (QoS:Quality ofService) information, and wherein bearing identification can be a network layer Operational Visit dot mark symbol (NSAPI:Networklayer Service Access Point Identifier);

Wherein, bearing identification is corresponding with carrying, makes network node can discern corresponding carrying through bearing identification; QoS information is used to let the network node be carry to distribute corresponding Internet resources, makes carrying can satisfy the requirement of QoS; The foundation of carrying between two network entities needs to participate in carrying the both sides that set up and distributes corresponding resource according to same QoS for this carries, and lets the other side know the resource of oneself distribution, then accomplishes the foundation of carrying between the both sides;

Step 202, SGSN send to PGW and create the PDP Context request message, and this message is carried bearing identification and QoS information, and according to the information of QoS information for the downlink bearing resource of carrying distribution;

Step 203, PGW return to SGSN and create the PDP Context response message, and this message is carried QoS information and bearing identification, and according to the information of QoS information for the up bearing resource of carrying distribution;

Step 204, SGSN send RAB (RAB:Radio Access Bearer) assignment request to RAN, and this request comprises bearing identification, QoS information, and according to the information of QoS information for the up bearing resource of carrying distribution;

Wherein, because the bearing identification that RAN can discern is RAB, so the bearing identification in the RAB assignment request converts RAB into by NSAPI, the last mapping relations of preserving between NSAPI and the RAB of SGSN;

After step 205, RAN receive the RAB assignment request, according to the RAB between bearing identification and QoS foundation and the UE;

Step 206, RAN return RAB to SGSN and assign response, inform SGSN with carrying situation about setting up, and carry information and the bearing identification of RAN according to the downlink bearing resource of QoS information distribution in this message;

If the QoS information when step 207 RAN sets up RAB changes; Then SGSN can redistribute the downlink bearing resource; And through upgrading PDP Context request message notice PGW; This message can be carried new QoS information and bearing identification, and the information of the downlink bearing resource of redistributing;

Step 208, PGW can redistribute up bearing resource according to new QoS information, and through upgrading PDP Context response message notice SGSN;

Step 209, SGSN are accepted message informing UE through PDP context activating and are carried to set up and accomplish, and the information of necessity such as QoS information etc. are passed to UE;

Sequencing on wherein step 207 and step 209 have no time.

Through above-mentioned flow process; Can, SGSN set up the carrying between UE and the PGW when being the SGSN of version before 3GPP version 7 reaches, but owing to the SGSN of 3GPP version 8 is connected with PGW through SGW; Thereby existing carrying is set up on the SGSN that scheme can not be applied in 3GPP version 8; When therefore in the SAE system, the SGSN of 3GPP version 8 being arranged, can not set up the carrying between UE and the PGW through this SGSN, thereby the resource of the network entity in the network is not fully utilized.

Embodiment

For make the object of the invention, technical scheme, and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, to further explain of the present invention.

Carrying establishing method embodiment provided by the invention one is as shown in Figure 3, comprising:

Step 301, PGW obtain the QoS information and first bearing identification, and according to the carrying between QoS information foundation and the RAN, this carrying is corresponding with first bearing identification;

PGW can directly set up and RAN between carrying; Also can when the carrying between foundation and the RAN, transmit the data between PGW and the RAN through SGW and/or SGSN; Following several kinds of situation are specifically arranged: first between (1) PGW foundation and the SGW carries; Carrying between SGW foundation and the RAN, this moment, SGSN only transmitted the data of SGW and RAN; (2) carrying between PGW foundation and the SGSN, the 3rd between SGSN foundation and the RAN carries, and this moment, SGW only transmitted the data between PGW and the SGSN; (3) carrying between PGW foundation and the UE, this moment, SGW transmitted the data between PGW and the UE with SGSN; (4) first between PGW foundation and the SGW carries, and second between SGW foundation and the SGSN carries, the 3rd carrying between SGSN foundation and the RAN;

Step 302, RAN are according to the radio bearer between foundation of the 2nd QoS information and the user equipment (UE), and radio bearer second bearing identification is corresponding, and the 2nd QoS information is corresponding with a QoS information, and second bearing identification is corresponding with first bearing identification.

In practical application; The QoS information that UE uses is different with the QoS information possibility that PGW uses; Thereby need be in the mapping relations between the QoS information of QoS information of preserving the UE use on SGSN or SGW or the RAN and PGW use; Thereby in data transmission procedure, QoS information is shone upon, make UE and PGW can both discern corresponding QoS information; Certainly, also can preserve corresponding mapping relations by UE or PGW self; Equally; The bearing identification that UE uses is different with the bearing identification possibility that PGW uses; Thereby need be in the mapping relations between the bearing identification of the bearing identification of preserving the UE use on SGSN or SGW or the RAN and PGW use; Thereby in data transmission procedure, bearing identification is shone upon, make UE and PGW can both discern corresponding bearing identification; Certainly, also can preserve corresponding mapping relations by UE or PGW self.

The embodiment of the invention all adopts preserves corresponding mapping relations by SGSN and describes, and the processing procedure of processing procedure and SGSN of being preserved mapping relations by other network entities such as SGW is similar, and this specification is not given unnecessary details other situation.Need to prove that step 302 can be carried out in the practical application, also can carry out simultaneously before step 301.

Carrying establishing method embodiment provided by the invention two is as shown in Figure 4, comprising:

Step 401, PGW send first message to SGW, trigger SGW and obtain the QoS information and first bearing identification;

PGW can initiatively send first message to SGW, as by the strategy triggering of PGW self etc.; Also can be passive send first message to SGW; Like the triggering of the trigger message of the network entity initiate to carry set up at other transmission first message etc. down; Can under from the triggering of second message of SGW, send first message like PGW, can certainly be from other network entities such as MME, SGSN etc.; Equally, it can be initiatively that SGW sends second message, also can be passive, for example can be from the triggering of the 3rd message of SGSN transmission second message down; It can be initiatively that SGSN sends the 3rd message, also can be passive, for example can be from the triggering of the 4th message of UE transmission the 3rd message down;

If comprise a QoS information in first message, SGW can directly obtain a QoS information from first message; If SGW self preserves a QoS information, then SGW can be directly from self obtaining a QoS information; If a QoS information is kept at other network entities in the network, then SGW can obtain a QoS information from the network entity of preserving a QoS information through certain interacting message;

Obtaining with obtaining of a QoS information of first bearing identification is similar, and a QoS information can be obtained from different network entities with first bearing identification, also can obtain through different modes;

Step 402, SGW carry according to first between QoS information foundation and the PGW, and first carrying is corresponding with first bearing identification;

Wherein, SGW can be described below according to the detailed process that first between QoS information foundation and the PGW carries:

SGW is first carry to distribute the first downlink bearing resource according to a QoS information, and the information of a QoS information, first bearing identification, the first downlink bearing resource is sent to PGW; PGW preserves the information of the first downlink bearing resource, if PGW is according to a QoS information distribution first up bearing resource, and the information of the first up bearing resource is sent to SGW preserves, and accomplishes first foundation of carrying; If PGW is as yet according to a QoS information distribution first up bearing resource,, the information of a QoS information, first bearing identification, the first up bearing resource is sent to SGW according to a QoS information distribution first up bearing resource; SGW preserves the information of the first up bearing resource, accomplishes the foundation of first carrying;

The downlink bearing resource or the up bearing resource that distribute can be the user plane resources, after carrying foundation, and just can be through up bearing resource and the downlink bearing resource transmission user face data that distributes;

Step 403, SGW carry according to second between QoS information foundation and the SGSN, and second carrying is corresponding with first bearing identification;

Wherein, SGW can be described below according to the detailed process that second between QoS information foundation and the SGSN carries:

SGW is second carry to distribute the second up bearing resource according to a QoS information, and the information of a QoS information, first bearing identification, the second up bearing resource is sent to SGSN;

SGSN preserves the information of the second up bearing resource, if SGSN is according to a QoS information distribution second downlink bearing resource, and the information of the second downlink bearing resource is sent to SGW preserves, and accomplishes second foundation of carrying;

If SGSN is as yet according to a QoS information distribution second downlink bearing resource,, the information of a QoS information, first bearing identification, the second downlink bearing resource is sent to SGW according to a QoS information distribution second downlink bearing resource; SGW preserves the information of the second downlink bearing resource, accomplishes the foundation of second carrying;

Step 404, the SGSN basis two QoS information corresponding with a QoS information set up and RAN between the 3rd carry, the 3rd carry corresponding with second bearing identification.

Step 405, RAN are according to the radio bearer between foundation of the 2nd QoS information and the UE, and second bearing identification that radio bearer is corresponding with first bearing identification is corresponding.

It is understandable that; Because second bearing identification is obtained through mapping by first bearing identification; Thereby first bearing identification and second bearing identification be one to one, thereby the carrying of creating is also corresponding with second bearing identification corresponding with first bearing identification time; Equally, QoS information and the 2nd QoS information are also like this, and the information that they comprised is identical, and just their form of expression is different.

Need to prove that the above-mentioned sequencing of not confirming between each, present embodiment be wherein a kind of realization situation just, in practical application, they can adopt arbitrarily sequencing to accomplish the foundation of carrying, and also can carry out simultaneously;

Wherein, The SGSN basis two QoS information corresponding with a QoS information set up and RAN between the 3rd carry detailed process and can be described below: SGSN is the 3rd to carry and distribute the 3rd up bearing resource according to the 2nd QoS information, and the 2nd QoS information, second bearing identification corresponding with first bearing identification and the information of the 3rd up bearing resource are passed to RAN; RAN preserves the information of the 3rd up bearing resource, according to the 2nd QoS information distribution the 3rd downlink bearing resource, the information of the 3rd downlink bearing resource is passed to SGSN, and SGSN preserves the information of the 3rd downlink bearing resource, accomplishes the 3rd foundation of carrying; In the process of setting up the 3rd carrying, RAN can be according to the radio bearer between foundation of the 2nd QoS information and the UE, and second bearing identification that radio bearer is corresponding with first bearing identification is corresponding;

Wherein, if RAN and SGW use the QoS information and the bearing identification of same type, then a QoS information is identical with the 2nd QoS information, and first bearing identification is identical with second bearing identification; If what RAN and SGW used is the QoS information of different editions; Then need on SGSN, preserve the mapping relations of QoS information; Mapping relations through QoS information go up SGW a QoS information mapping of using and go up the 2nd QoS information of using as RAN, and the QoS information mapping that for example SGW is gone up the version 8 that uses is the last QoS information of the version 7 of use of RAN; Equally; If RAN uses different bearing identifications with SGW; Then need on SGSN, preserve the mapping relations of bearing identification; Mapping relations through bearing identification are mapped as second bearing identification that RAN upward uses with first bearing identification that SGW goes up use, for example SGW are gone up the bearing identification that uses and are mapped as the upward network layer Operational Visit dot mark symbol (NSAPI:Network layer Service Access Point Identifier) of use of RAN;

In the practical application, RAN can adopt the radio bearer between following flow process foundation and the UE: RAN sends to UE with the 2nd QoS information, second bearing identification; UE is according to the QoS information distribution first radio bearer downlink bearing resource, and the information of the QoS information of distributing the first radio bearer downlink bearing resource institute basis, second bearing identification, the first radio bearer downlink bearing resource is sent to RAN; RAN preserves the information of the first radio bearer downlink bearing resource; According to the up bearing resource of QoS information distribution first radio bearer that distributes the first radio bearer downlink bearing resource institute basis, the information of the QoS information of distributing the first radio bearer downlink bearing resource institute basis, second bearing identification, the up bearing resource of first radio bearer is sent to UE; UE preserves the information of the up bearing resource of first radio bearer, accomplishes the foundation of radio bearer;

Because the resource that UE can distribute is that network side is unknown, so though send the 2nd QoS information to UE, UE not necessarily can distribute the desired resource of the 2nd QoS information; Thereby, after UE receives the 2nd QoS information, need judge whether to be that radio bearer distributes the first radio bearer downlink bearing resource, if then directly set up radio bearer according to the 2nd QoS information according to the 2nd QoS information; If not, then need confirm the 3rd QoS information according to its other resources situation, set up radio bearer according to the 3rd QoS information then by UE;

When UE adopts the 3rd QoS information to set up radio bearer, then need the SGW basis four QoS information corresponding to set up second and carry and first carrying with the 3rd QoS information; If second carrying and first carrying are set up, then need SGW to rebulid second and carry and first carrying according to the 4th QoS information, promptly upgrade second and carry and first carrying, make second carrying and first carry the requirement that can satisfy the 4th QoS information.

From the above, use present embodiment, can be in 3GPP version 8, when SGSN directly is connected with SGW, communicates by letter with PGW through SGW, thereby set up the carrying between UE and the PGW, the resource of each network entity in the network is fully used.

In practical application; May set up a plurality of carryings between same UE and the same PGW; This moment can be through getting up transmitting data stream and corresponding bearing association with a corresponding sign of carrying; In practical application, can adopt transmission stream template (TFT:Traffic Flow Template), at this moment:

The uplink transmission stream template corresponding with carrying that PGW can distribute is delivered to UE with uplink transmission stream template in carrying the process of setting up; Equally, UE can distribute the corresponding downstream transmission stream template, in carrying the process of setting up, the downlink transfer flow template is delivered to PGW.

From the above, the foundation of carrying between UE and the PGW can be triggered by the arbitrary network entity in the network, as being triggered by PGW, being triggered, triggered, triggered etc. by PGW by SGW by UE, introduces above-mentioned several kinds of situation as follows respectively:

One, triggers the situation about setting up of carrying by PGW

Carrying establishing method embodiment provided by the invention three is as shown in Figure 5, has described by PGW and has triggered the situation about setting up of carrying, and it possibly be the triggering that receives some situation that the carrying that PGW initiates is set up; For example, from downstream node, like the trigger messages of SGW, SGSN, RAN, UE etc.; From other system's interdependent node; Like the trigger messages of MME etc., from upstream node, like the trigger messages of strategy with charging regulation module (PCRF:Policy and Charging Rules Function); Perhaps trigger etc., comprising by PGW oneself:

Step 501, PGW send out the establishment bearing request message to SGW;

After PGW obtains a QoS information from own or other network nodes; According to a QoS information is that first between PGW and the SGW carries the distribution first up bearing resource; Send the establishment request message to SGW, can comprise information, a QoS information and first bearing identification of the first up bearing resource in this establishment bearing request message; In practical application, can also be further and up TFT information;

Step 502, SGW send to SGSN and create bearing request message;

After SGW receives the establishment bearing request message from PGW, preserve necessary information, like information, a QoS information and first bearing identification of the first up bearing resource;

SGW is that second between SGW and the SGSN carries the distribution second up bearing resource according to a QoS information; Send the establishment bearing request message to SGSN, this establishment bearing request message can comprise information, a QoS information and first bearing identification of the second up bearing resource; If SGW has obtained up TFT, this establishment bearing request message can further include up TFT;

Step 503, SGSN send requesting activation PDP Context message to UE;

SGSN sends requesting activation PDP Context message to UE, can comprise information such as QoS information, up TFT, bearing identification in this message; Wherein, On SGSN, possibly carry out the mapping of QoS and the mapping of bearing identification; If carried out the mapping of QoS and the mapping of bearing identification; Then the included QoS information of requesting activation PDP Context message is by the 2nd QoS information after the QoS information mapping, and included bearing identification is by second bearing identification after the mapping of first bearing identification in the requesting activation PDP Context message; If do not carry out the mapping of QoS and the mapping of bearing identification, then the included QoS information of requesting activation PDP Context message is a QoS information, and the included bearing identification of requesting activation PDP Context message is first bearing identification;

Step 504, UE send PDP context activating request message to SGSN;

UE receives after the requesting activation PDP Context message, can preserve necessary information, like QoS information, bearing identification etc.; If requesting activation PDP Context message comprises up TFT, UE also can carry out related with this carrying up TFT; UE sends PDP context activating request message to SGSN, can carry information such as QoS information in this message, and the QoS information of wherein carrying in this message possibly be the 3rd QoS information after UE reselects, and also can be the 2nd QoS information; As received up TFT, then can also further carry the descending TFT corresponding in this message with up TFT;

Step 505, SGSN send the RAB assignment request message to RAN;

The foundation of the radio bearer between step 506, RAN completion and the UE;

Step 507, RAN return RAB to SGSN and assign response message;

Step 505,506 and 507 concrete processing procedure and step 204,205 and 206 processing procedure are similar, repeat no more here;

Step 508, SGSN return the establishment bearing response message to SGW;

SGSN is that second carrying distributes the second downlink bearing resource according to a QoS information; May occur in the practical application not being that according to a QoS information be the situation that second carrying distributes the second downlink bearing resource; Not to adopt the two QoS information corresponding for example with a QoS information at UE; But during according to the descending radio bearer resources of the 3rd QoS information distribution, SGSN can the basis four QoS information distribution second downlink bearing resource corresponding with the 3rd QoS information; SGSN returns the establishment bearing response message to SGW, can comprise the information of a QoS information, first bearing identification and the second downlink bearing resource in this message; If SGSN has received the descending TFT from UE, can also comprise descending TFT in this message;

Step 509, SGW return the establishment bearing response message to PGW;

SGW preserves corresponding information after receiving the establishment bearing response message from SGSN, like information of a QoS information, first bearing identification and the second downlink bearing resource etc.; According to a QoS information is that first carrying distributes the first downlink bearing resource, same, may occur in the practical application not being that according to a QoS information be the situation that first carrying distributes the first downlink bearing resource; SGW returns the establishment bearing response message to PGW, can comprise the information of a QoS information, first bearing identification and the first downlink bearing resource in this message; If SGW has received the descending TFT from SGSN, can also comprise descending TFT in this message;

Step 510, SGSN return the PDP context activating response message to UE;

SGSN can return the PDP context activating response message to UE behind the RAB appointment response message that receives from RAN, the corresponding carrying of notice UE has been created and finished;

Need to prove; Fig. 5 has only described a kind of implementation under this situation; In practical application, the sequencing between each step may change, and all is to occur in after the step 507 like step 508 and step 510; Between them can be sequencing arbitrarily, also can carry out simultaneously;

Use present embodiment, can be in 3GPP version 8, when SGSN directly is connected with SGW, communicate by letter with PGW through SGW, trigger by PGW and set up the carrying between UE and the PGW, the resource of each network entity in the network is fully used.

Fig. 6 has described carrying establishing method embodiment four provided by the invention, has also described by PGW and has triggered the situation of carrying foundation, comprising:

Step 601, PGW send out the establishment bearing request message to SGW;

The foundation that beginning first is carried;
