Description
Technical field
The present invention relates to network communications technology field, relate in particular to a kind of method that makes each entity service quality keep uniformity in the network.
Background technology
GPRS serving GPRS support node (SGSN) is GPRS/universal mobile telecommunications system (GPRS/UMTS) packet domain core network network (CN) equipment, mainly finishes the route and the functions such as forwarding, encryption and authentication, session management, mobile management, Logical Link Management, ticket generation and output of packet data package.
The function of SGSN comprises: business datum is carried out block domain data route and forwarding between travelling carriage (MS) and Gateway GPRS Support Node (GGSN).
SGSN has mobile management function and conversation management functional.
Mobile management function among the SGSN (MM, Mobility Management) has defined the activity under different user MM states.In GPRS network, user's MM state is divided into free time (IDLE), standby (STANDY) and ready (READY).In the UMTS network, user's MM state is divided into the packet domain mobile management and separates (PMM-DETACHED, Packet MobilityManagement), the packet domain mobile management free time, (PMM-IDLE, Packet Mo bilityManagement) is connected (PMM-CONNECTED, PacketMobility Management) with the packet domain mobile management.The various information relevant with state are kept in the MM context (Context) of MS and SGSN.The mobile management function by adhere to, signaling processes such as separation, Routing Area Update, realize the contextual establishment of MM, revise and delete, and the migration of state.
Conversation management functional among the SGSN (SM, Session Management) is between mobile management function and user's face, and the no response data delivery service of using bottom more to provide is that user's face provides the connection management service to high level.It finishes the controlled function that core network SGSN is set up, revises and discharge to the GTP tunnel between the GGSN (GPRS Tunnelling Protocol Tunnel) on the one hand; Finish under the Iu pattern controlled function on the other hand to foundation, modification and the release of RAB RAB (Radio AccessBearer) between SGSN and Radio Access Network (RAN, Radjo the AccessNetwork)/MS (Mobile Station).Conversation management functional is realized processes such as the contextual activation of particular packet data protocol (PDP), deexcitation, modification.Only after activating PDP Context, just can carry out the transmission of business datum.In SGSN, GGSN, MS, all preserve PDP Context, preserved the information relevant in the PDP Context with specific PDP.Session management only just can carry out under the situation that the MM context has been set up.
MS inserts SGSN by wireless access network, and different wireless access networks uses different interface protocols to be connected with SGSN.
When BSS is connected to SGSN by Gb Interface, at this moment the connection mode of network is the Gb pattern.
(RNC, Radio Network Controller) is connected to SGSN by the Iu interface when the BSS/ radio network controller, and at this moment the connection mode of network is the Iu pattern.
The user is in the process that moves, and the route district can change.When the user under the Iu pattern, if new and old route district belongs to same SGSN, the Routing Area Update flow process (IntraSGSN Routeing Area Update Procedure) in the SGSN then takes place; If new and old route district belongs to different SGSN, the Routing Area Update flow process (Inter SGSN Routeing AreaUpdate Procedure) between SGSN then takes place.
The user also may use dissimilar wireless access networks in the process that moves, switch switching or the system from the Iu pattern to the Gb pattern the system of generation from the Gb pattern to the Iu pattern.The user is initially under the Gb pattern, switches to the Iu pattern, if Iu mode wireless Access Network uses identical SGSN with Gb mode wireless Access Network, the Gb pattern that then takes place in the SGSN arrives switching flow between the Iu modular system; If Iu mode wireless Access Network uses different SGSN with Gb mode wireless Access Network, the Gb pattern that then takes place between SGSN arrives switching flow between the Iu modular system.
QoS is meant the PDP service quality that each network entity is consulted out in activation process, it has defined the service quality that this PDP Context can access under state of activation, should be present in each network entity such as MS, RNC, BSS, SGSN and GGSN, have only each network entity all to guarantee this service quality, the user could finally carry out obtaining due service in the transfer of data.
In the prior art, carry out between SGSN that network switches and the location after, new side SGSN needs to consult again QoS, and the QoS that newly consults by update packet data protocol contexts request (Update PDP ContextRequest) message handle sends to GGSN, GGSN might be able to not reach the qos requirement of new side SGSN, at this moment then hold consultation, reduce QoS, the QoS that will reduce after consulting in update packet data protocol contexts response (Update PDP Context Response) message sends to SGSN.
In the prior art, the QoS that carries out each entity in network switching or back, the location network may be inconsistent, below illustrates.
Between SGSN between Iu pattern Routing Area Update flow process or SGSN the Gb pattern in switching flow between the Iu modular system, new side SGSN may be because the reasons such as ability of self change QoS, GGSN also might consult to reduce QoS, brings SGSN in update packet data protocol contexts response (Update PDP ContextResponse) message.Under these situations, new side SGSN with new QoS notice MS, does not cause the QoS of network each entity inconsistent.
Between SGSN in the reorientation flow process, new side SGSN may be because the reasons such as ability of self change QoS, target RAN may consult to reduce QoS, in re-positioning request announcement (RelocationRequest Acknowledge) message, carry to SGSN, GGSN also might consult to reduce QoS, brings SGSN in Update PDP Context Response message.In these cases, new side SGSN with new QoS notice MS, does not cause the QoS of network each entity inconsistent.
The QoS of network each entity is inconsistent, can make quality of services for users can not get guaranteeing, causes the unnecessary waste of Internet resources simultaneously.

Embodiment
Core of the present invention be when MS carry out that network between SGSN switches or reorientation after, will be updated in the network others entity in the new service quality of side SGSN through the MS that consults to obtain; When with MS when the service quality of new side SGSN is updated in the network other entity, other entity need upgrade in service quality and finish the back and reply to SGSN and upgrade response in the network, confirms to upgrade whether success; Whether the service quality need carry renewal in this renewal response after consults to have reduced service quality to detect in renewal process.
More specifically say, the present invention carry out according to MS that network between SGSN switches or during reorientation by certain network entity QoS quality inconsistent situation of each entity QoS in the network that causes that descends, MS carry out that network between SGSN switches or reorientation after, whether the service quality to this MS of each entity is identical to the service quality of this MS with the SGSN that obtains through negotiation in the detection network, if service quality is identical, the service quality that then keeps this entity, if the service quality difference, then will be updated in this entity through the service quality of the SGSN that consults acquisition.When the service quality with SGSN was updated in the network other entity, other entity need upgrade in service quality and finish the back and reply to SGSN and upgrade response in the network, confirms to upgrade successfully; QoS after in this renewal response, need carrying renewal, original QoS among this QoS and the SGSN is compared, whether detection consults to have reduced QoS in renewal process, if do not reduce, then keep original QoS among the SGSN,, then the QoS through having consulted to reduce is updated among the SGSN if really reduce, use this QoS to carry out QoS and upgrade, guarantee the QoS unanimity of a designated entities in the network as other entity in the network.
Below in conjunction with the specific embodiment of the invention accompanying drawing the present invention is elaborated.
Whole specific embodiment of the present invention all is that there was PDP Context in MS before flow process began with hypothesis on old side SGSN, and old side SGSN to have sent PDP Context to new side SGSN be prerequisite.
Figure 2 shows that Iu mode switch flow process QOS solution signaling process schematic diagram between the embodiment of the invention one SGSN.
Between SGSN in the Iu switching flow, owing to new side SGSN may be because the reasons such as ability of self change the QoS of new side SGSN, GGSN also may reduce QoS in negotiation, the QoS of the QoS of so new side SGSN and MS, new side RAN and GGSN is probably inconsistent, therefore need be between SGSN after the Iu mode switch QoS among the new side SGSN be updated in other entities in the network, the QoS of each entity is consistent.
As shown in Figure 2, after switching to new side SGSN from old side SGSN, for the QoS among the new side SGSN being updated in other entities in the network QoS of each entity is consistent, need beginning RAB to set up flow process, after RAB sets up, the SGSN of new side is updated to other entities in the network with the QoS of this locality, is updated to GGSN, new side RAN and MS in the present embodiment.
Figure 3 shows that the new side SGSN process chart of Iu mode switch flow process QoS solution between the embodiment of the invention two SGSN.
As shown in Figure 3, this flow chart introduced when carrying out Iu mode switch between SGSN, upgrade and unified network in the concrete grammar of each entity QoS.
Step 31, flow process begin, according to consult the QoS of the side SGSN that makes new advances, be saved among the QoSNeg.
Step 31a, new side SGSN begin handoff procedure.
Step 31b, new side SGSN receive the SGSN context from old side SGSN, comprise request QoS, negotiation QoS and signatory QoS that PDP Context uses at old side SGSN in this SGSN context.
Step 31c, new side SGSN negotiate a new QoS according to PDP Context at the QoS that the QoS of old side request, signatory QoS and new side SGSN self support, note is QoSNeg.
Do not set up process if do not need to carry out RAB in the step 32 SGSN switching flow, then new side SGSN uses the QoSNeg through consulting to obtain to send the QoS update request to GGSN;
GGSN upgrades behind the local QoS to send to SGSN and upgrades response, and the QoS situation of GGSN this locality is sent to new side SGSN.
Step 33, might reduce QoS because GGSN consult to upgrade in the process of local QoS, therefore new side SGSN checks according to the renewal response of GGSN whether QoS reduces.
If step 34a GGSN consults to have reduced QoS, the QoS after then will consulting to reduce is updated among the QoSNeg of new side SGSN;
If step 34b GGSN consults not reduce QoS, then do not upgrade QoSNeg.
Step 35, after upgrading according to the QoS of GGSN or keeping former QoSNeg, SGSN initiates RAB to RAN and rebuilds flow process.
Step 35a, in RAB rebuilds flow process, SGSN uses QoSNeg to send RAB to RAN and sets up request;
Step 35b, RAN are receiving that RAB sets up the request back and replys foundation request response, and QoS judges whether QoS reduces among the RAN that carries in this response by detecting.
If step 36a RAN consults to have reduced QoS, then the QoS through having consulted to reduce is updated to QoSNeg, by using the QoSNeg upgraded to send update request, and upgrade to respond at the GGSN that receives and then judge that QoSNeg is whether consistent with the QoS that PDP Context uses in old side SGSN to GGSN;
If step 36b RAN consults not reduce QoS, then need not to upgrade QoSNeg, judge that by using original QoSNeg QoSNeg is whether consistent with the QoS that PDP Context uses in old side SGSN.
If the QoS that step 37a QoSNeg and PDP Context use in old side SGSN is inconsistent, then send the request of modification to MS, request is revised as QoSNeg the QoS of MS, after the QoS of MS modification is finished, MS replys and revises response, confirming that revising errorless back flow process finishes, and realizes the QoS of each entity in the network is unified;
If step 37b QoSNeg is consistent with the QoS that PDP Context uses in old side SGSN, then flow process finishes, and realizes the QoS of each entity in the network is unified.
Set up process if need to carry out RAB in the step 38 SGSN switching flow, then new side SGSN uses the QoSNeg through consulting to obtain to initiate RAB to RAN and sets up request;
RAN receives as answer RAB behind the QoSNeg of RAB foundation request and sets up response, and newly side SGSN receives this response.
Step 39, judge whether successfully to set up RAB, if can not set up RAB, then execution in step 32; If can set up RAB, judge then whether RAN has reduced QoS in QoS consults.
If step 310 RAN has reduced QoS in QoS consults, then the local QoS that is lowered through negotiation of RAN is updated among the QoSNeg, use the QoSNeg after upgrading to send update request to GGSN;
If RAN has not reduced QoS in QoS consults, then need not to upgrade QoSNeg, directly use QoSNeg to send update request to GGSN.
Step 311, GGSN are updated to this locality with QoSNeg after consulting, and reply and carry the renewal response of upgrading back QoS, are used for detecting GGSN and whether have reduced QoS in negotiation.
If step 312 GGSN does not reduce QoS in negotiation, then execution in step 37a or step 37b, process ends;
If GGSN has reduced QoS in negotiation, then the QoS through having consulted to reduce is updated among the QoSNeg, and the QoS of RAN is updated to QoSNeg, execution in step 39a or step 39b then, process ends realizes the QoS of each entity in the network is unified.
Figure 4 shows that Iu pattern Routing Area Update schematic flow sheet between embodiment of the invention Three S's GSN.
As shown in Figure 4, step 41 to step 419 is used to realize the MS process that switch in Iu pattern route district between SGSN, and step 420 to step 424 is used for being implemented in the process that back renewal, unified each entity QoS of network are switched in the route district.
The content that also exists QoS to upgrade in the process that switch in Iu pattern route district between SGSN: in step 49, new side SGSN at first negotiates a new QoS according to PDP Context at the QoS that the QoS of old side request, signatory QoS and new side SGSN self support, sends to GGSN by Update PDP ContextRequest message; The QoS that GGSN returns in Update PDP Context Response message may be consulted to reduce, and SGSN adopts this QoS as the QoS that consults.
The renewal of each entity QoS in the network that after switching is finished, carries out, unified comprising:
Whether the QoS that step 423, judgement are consulted is identical with the QoS that PDP Context uses in old side, if different, the QoS of SGSN after MS sends Modify PDP Context Request message informing MS renewal; If identical, process ends.
The QoS after if step 424 MS accepts to upgrade, MS sends Modify PDPContext Accept message to SGSN; The QoS after if MS does not accept to upgrade, MS will initiate PDP deexcitation flow process.
The Gb pattern between the embodiment of the invention four SGSN that Figure 5 shows that arrives switching flow schematic diagram between the Iu modular system.
As shown in Figure 5, step 51 to step 518 be used to realize MS in Gb pattern between SGSN to the process of switching between the Iu modular system, step 519 to step 523 is used for being implemented in the route district and switches that the back is upgraded, the process of unified each entity QoS of network.
Also there is the content that QoS upgrades in the handoff procedure between the Iu modular system in the Gb pattern between SGSN: in step 58, new side SGSN at first negotiates a new QoS according to PDP Context at the QoS that the QoS of old side request, signatory QoS and new side SGSN self support, sends to GGSN by Update PDPContext Request message.The QoS that GGSN returns in Update PDP ContextResponse message may be consulted to reduce, and SGSN adopts this QoS as the QoS that consults.
The renewal of each entity QoS in the network that after switching is finished, carries out, unified comprising:
Whether the QoS that step 522, judgement are consulted is identical with the QoS that PDP Context uses in old side, if different, the QoS of SGSN after MS sends Modify PDP Context Request message informing MS renewal; If identical, process ends.
The QoS after if step 523 MS accepts to upgrade, MS sends Modify PDPContext Accept message to SGSN; The QoS after if MS does not accept to upgrade, MS will initiate PDP deexcitation flow process.
Figure 6 shows that the reorientation schematic flow sheet between the embodiment of the invention five SGSN.
As shown in Figure 6, step 61 to step 614 is used to realize the process of MS reorientation between SGSN, and step 615 to step 619 is used for realizing that MS upgrades, the process of unified each entity QoS of network after reorientation.
The content that also exists QoS to upgrade in the process of MS reorientation between SGSN:
In step 64, new side SGSN at first negotiates a new QoS according to PDP Context at the QoS that the QoS of old side request, signatory QoS and new side SGSN self support, sends to target RAN by RelocationRequest message.Target RAN returns to new side SGSN with the successful RAB information of setting up in Relocation RequestAcknowledge message, QoS may be consulted reduction, and SGSN adopts this QoS as the QoS that consults.
In step 613, step 614, SGSN uses the QoS that consults to send UpdatePDP Context Request message to GGSN, the QoS after notice GGSN upgrades.If GGSN consults to have reduced QoS in Update PDP Context Response response, SGSN adopts this QoS as the QoS that consults, and enters step 616; Otherwise enter step 618.
It is optional step that step 615 is carried out routing region updating, can carry out synchronously with step 616 to step 619
The renewal of each entity QoS in the network that carries out in repositioning process and after finishing, unified comprising:
Step 616, SGSN use the QoS that consults to send RAB to RAN and revise request, the QoS after notice RAN upgrades.
Step 617, RAN send RAB to SGSN and revise response, confirm new QoS.
Whether the QoS that step 618, judgement are consulted is identical with the QoS that PDP Context uses in old side, if different, the QoS of SGSN after MS sends Modify PDP Context Request message informing MS renewal; If identical, process ends.
The QoS after if step 619 MS accepts to upgrade, MS sends Modify PDPContext Accept message to SGSN; The QoS after if MS does not accept to upgrade, MS will initiate PDP deexcitation flow process.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
