Description
Technical field
The present invention relates to evolution grouping domain system (EPS, EvolvedPacketSystem) technology, espespecially a kind of bearing modification method and system.
Background technology
In order to keep 3-G (Generation Three mobile communication system) in the competitiveness of the communications field, third generation partner program (3GPP, 3rdGenerationPartnershipProject) standard working group is just being devoted to the research of evolution grouping domain system (EPS, EvolvedPacketSystem).
Fig. 1 is the structure composed schematic diagram of existing EPS, as shown in Figure 1, EPS mainly includes the universal terrestrial access network (E-UTRAN of evolution, and the packet-based core networks of evolution (EPC, EvolvedPacketCore) two parts EvolvedUniversalTerrestrialRadioAccessNetwork). Wherein, EPC can support that user is from GSMEDGE wireless access network (GERAN, and the access of universal land radio access web (UTRAN, UniversalTerrestrialRadioAccessNetwork) GSMEDGEradioaccessnetwork).
In EPC, include home subscriber data server (HSS, HomeSubscriberServer), mobility management unit (MME, MobilityManagementEntity), gateway (S-GW, ServingGateway), grouped data network gateway (P-GW, PDNGateway), Serving GPRS Support Node (SGSN, ServingGPRSSupportNode) and strategy and charging regulation function entity (PCRF, PolicyandChargingEnforcementFunction), wherein
HSS is the permanent storage place of user contracting data, is positioned at the home network of user's signing;
MME is the user contracting data storage place in current network, for being responsible for tracking under Non-Access Stratum (NAS layer, the Non-AccessStratum) signaling management of terminal to network, user's idle pulley and paging management function and bearer management;
S-GW is the gateway that core net arrives wireless system, for being responsible for terminal to the data buffer storage under the user plane bearer of core net, terminal idle mode, the function of network side initiating business request, lawful interception and packet routing and forwarding capability;
P-GW is the gateway of EPS and EPS external network, for being responsible for the functions such as the IP address distribution of terminal, billing function, packet packet filtering, strategy application;
SGSN is the business support point that GERAN and UTRAN user accesses EPC network, functionally similar with MME, for being responsible for the functions such as the location updating of user, paging management and bearer management;
PCRF, is used for being responsible for providing policy control and charging regulation to PCEF.
In EPS, in order to reduce the space interface signaling between UE and core net, introduce idle pulley and reduce the function of signaling (ISR, IdlemodeSignalingReduction). After ISR function is activated, there is the UE of UTRAN/GERAN and E-UTRAN access function simultaneously, it is possible to be registered to MME and SGSN simultaneously. So, when UE moves under Access Network two kinds different, UE will not initiate (interRAT between wireless access network, RadioAccessTechnology) routing region updating (RAU, or tracking area update (TAU, TrackingAreaUpdate) RoutingAreaUpdate). Utilize ISR function, decrease signaling unnecessary between UE and core net.
Fig. 2 is the existing UE schematic flow sheet activating ISR function, as illustrated in fig. 2, it is assumed that UE begins by E-TURAN accesses (if it is similar first to access network condition from UTRAN/GERAN, repeat no more here) of network, specifically includes following steps:
Step 201:UE is registered by E-UTRAN to MME, if UE has the unique temporary UE identifier (GUTI in the effective whole world, GloballyUniqueTemporaryIdentity) or packet temporary mobile subscriber identity (P-TMSI, Packet-TemporaryMobileSubscriberIdentity), then in attachment request, P-TSMI or GUTI is carried.
The inspection of UE is passed through by step 202:MME, and weight, to the more newly requested message of HSS launch position, by Self address information reporting to HSS, completes the registration in HSS.
Step 203:HSS updates response message to MME home position, wherein carries the CAMEL-Subscription-Information of UE.
Step 204:MME initiates the establishment conversation request message for setting up default bearing by SGW to PGW.
After step 205:PGW sets up default bearing success, send establishment conversational response message by SGW to MME.
Step 206:MME is that UE distributes new GUTI and tracking area identification list (TAIlist), and carries and return to UE in attachment response message, also carries default bearing activation request message in attachment response message.
Step 207:UE receives GUTI and the TAIlist of distribution, and after completing default bearing foundation, sends attachment completion message to MME.
Step 208:UE moves in the Route Area (RA) of UTRAN/GERAN, and UE initiates Routing Area Update request message, and the GUTI of acquisition is mapped as P-TMSI, and is included in request message in request and carries GUTI mark.
Step 209:SGSN obtains the contextual information of UE to MME.
After UE is completed various verification by step 210:MME, return the contextual information of this UE to SGSN. If this MME supports ISR function, the context response of this return is also carried ISR ability information, be used for indicating MME and support ISR function.
Step 211:SGSN checks the need for reselecting S-GW, if need not and SGSN also support ISR function, then, SGSN thinks that ISR function can activate. Adding ISR in context response and activate instruction, notice MME can continue to safeguard the context of this UE.
Step 212:SGSN sends bearer update request to S-GW, carries ISR and activates instruction, be used for notifying that S-GW, ISR function is activated in bearer update is asked.
Step 213:S-GW activates mark at locally located ISR, and sends bearer update response to SGSN.
Step 214:SGSN is carrying self address or coding information in the HSS position updating request sent.
Step 215:HSS judge to be currently accessed as SGSN, it is judged that perform double; two registration, namely need not send canceling position request to the MME registered before. HSS returns the location updating response message of the CAMEL-Subscription-Information carrying UE to SGSN.
Step 216:SGSN sends Routing Area Update to UE and accepts message, accepts to carry ISR in message at Routing Area Update and activates instruction and the P-TMSI that SGSN is UE distribution.
Step 217:UE returns Routing Area Update completion message to SGSN.
Can be seen that from the flow process shown in Fig. 2, for the ISR UE activated, Mobility Management Entity (MME or SGSN) needs all to retain effective contextual information at two networks, thus ensureing that the signaling plane information such as the follow-up paging to UE can be respectively sent to MME and SGSN from S-GW; Meanwhile, SGW is also required to retain the relevant information of MME and SGSN simultaneously, thus ensure that follow-up signaling and downlink data notification message can notify two network elements of MME and SGSN simultaneously. UE is when activating ISR, although can be simultaneously held under two RAT and register effectively, but at a time can only keep state of activation under a RAT.
In prior art, if the subscription data of user changes, it is possible to the service quality (QoS) that can trigger carrying revises process, does not now activate ISR, namely UE is only in MME or SGSN registration effectively. Specifically as it is shown on figure 3, the schematic flow sheet that Fig. 3 is existing bearing modification, Fig. 3 is described for MME:
Step 301:HSS initiates subscription data amendment process, by inserting user contracting data message, issues the subscription data of the UE after renewal.
Step 302:MME returns to HSS and inserts subscription data response message.
Step 303:MME judges that the subscription data such as QoS that the currently active carrying is relevant changes.
Step 304～step 305:MME initiates bearing modification order by SGW to PGW, carries the qos parameter after signing change in bearing modification order.
Step 306～step 307:PGW is according to the qos parameter after the signing change received, determine whether to perform QoS amendment, if needing amendment, then PGW sends renewal bearing request message by SGW to MME, carries amended qos parameter in updating bearing request message. In this step, it may be judged whether need amendment and how to revise the technology as well known to those skilled in the art that belongs to, and it implements unrelated to the invention, no longer describes in detail here.
Step 308:MME finds that UE is in Idle state, then send beep-page message to eNB, eNB paging UE.
Step 309:UE by eNB to MME initiating business request message.
Step 310:MME sends initial context to eNB and sets up request, sets up the contextual information carrying UE in request at initial context, comprises the qos parameter that UE carrying is relevant.
Step 311:eNB is that UE sets up radio open carrying.
Step 312:eNB returns initial context response message to MME, carries tunnel end mark and the address information of eNB in initial context response message.
Tunnel end mark and the address information of eNB are sent to SGW by step 313～step 314:MME.
Step 315:MME, by the QoS of the PGW carrying revised, is modified bearing request message and informs UE.
Step 316:UE updates QoS information, and returns amendment bearing response message to MME.
Step 317～step 318:MME returns renewal bearing response message by SGW to PGW.
Step 313～step 314, the execution with step 315～step 318 is without sequencing.
If in step 308, MME finds that UE is in connected state, then step 308～step 314 can be omitted.
From flow process shown in Fig. 3, if UE has activated ISR function, then, when the subscription data of HSS changes, HSS can be all inserted into subscription data to MME and SGSN simultaneously. But, owing to MME and SGSN is not aware that the state under another Access Network, in order to ensure UE, SGW and PGW can obtain renewal in time after qos parameter, MME and SGSN needs simultaneously to initiate bearing modification process to SGW and PGW. In existing bearing modification process, owing to the state of UE to be not added with distinguish, too much core network signalling can be caused.

Instruction information in this step can be indicated by reason (cause) value in the existing bearing modification failed message of extension, or in this bearing modification failed message, newly-increased element (IE) carries this instruction message, or uses newly-increased message to carry this instruction information.
This instruction information can be that display is carried or implicit expression is carried. Display is carried to refer to and must be carried the instruction whether activated in message. If implicit expression is carried refers to a kind of situation of instruction expression that carries in message (ISR deexcitation or reservation ISR are activated), do not carry another situation of expression.
Step 711a:UE updates QoS information, and indicates information to decide whether to continue to keep ISR to activate according to the ISR in amendment bearing request message, and UE returns amendment bearing response message to SGSN.
Step 712a～step 713a:SGSN returns renewal bearing response message by SGW to PGW.
So far, UE bearing modification in UTRAN/GERAN is completed.
In E-UTRAN, including:
Step 701b:HSS initiates subscription data amendment process, by inserting subscriber data message, issues the subscription data of the UE after renewal.
Step 702b:MME returns to HSS and inserts subscription data amendment response message.
Step 703b:MME is according to the subscription data obtained, it is judged that the qos parameter that the currently active carrying is relevant changes, and UE have activated ISR and is in Idle state.
Step 704b:MME sends bearing modification order to SGW, carries amended qos parameter in bearing modification order.
Step 705b:SGW have activated ISR and another RAT according to UE, is namely in connected state under GERAN/UTRAN, it is determined that without bearing modification order is sent to PGW.
The qos parameter carried in the more new bearer request that in step 706b:SGW waiting step 707a, PGW returns, and judge that it is identical with the qos parameter comprised in step 704a or 704b whether unanimously (identical), if it is consistent, then SGW returns bearing modification failed message to MME, and notice UE is in connected state and the successfully modified instruction information of QoS under another RAT; If it is inconsistent, SGW returns bearing modification failed message to MME, notice UE is in the instruction information of connected state under another RAT.
Optionally, SGW can also comprise the amended qos parameter of PGW in bearing modification failed message.
In this step, this instruction information can be indicated by reason (cause) value in the existing bearing modification failed message of extension, or in this bearing modification failed message, newly-increased element (IE) carries this instruction message, or uses newly-increased message to carry this instruction information.
Step 707b, after MME is notified, instruction information and executing subsequent operation according in bearing modification failed message: if it is indicated that information is in connected state for notice UE under another RAT and QoS is successfully modified, the QoS that then MME maintenance was revised, and under this Access Network, it is not fully complete bearing modification process without labelling UE; Be under another RAT in connected state and notification message do not carry amended qos parameter if it is indicated that information is UE, then MME this locality preserves the HSS QoS revised, and is labeled as UE and is not fully complete bearing modification process under EUTRAN; Being under another RAT in connected state and notification message carry amended qos parameter if it is indicated that information is UE, MME keeps the QoS revised, and is not fully complete bearing modification process under this Access Network without labelling UE.
Being in connected state in E-UTRAN for UE, be in the situation of Idle state in UTRAN/GERAN, implement similar with flow process shown in Fig. 7, on Fig. 7 basis, those skilled in the art are readily available, and do not repeat here.
The above, be only presently preferred embodiments of the present invention, is not intended to limit protection scope of the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
