Technical field
The present invention relates to communication technical field, relate in particular to control method and terminal that a kind of session management is kept out of the way timer.
Background technology
Session management congestion control based on APN (Access Point Name, APN)
As general packet radio service technological service support node (Serving GPRS SUPPORTNODE, SGSN)/Mobility Management Entity (Mobility Management Entity, MME) monitor network and APN occurs when congested, SGSN/MME can refusing user's equipment (User Equipment, UE, claim again terminal) the session management request message relevant with congested APN occurs that send, and in refuse information, carry session management and keep out of the way timer (Session Management back-off timer, SMback-off timer) value; SGSN/MME is initiation packet data network (Public DataNetwork initiatively, PDN) connect deactivation process and delete the PDN connection relevant with congested APN occurs, and in the grouping system bearer context request of deexcitation evolution/deexcitation packet data protocol context request (DEACTIVATE EPS BEARER CONTEXT REQUEST/DEACTIVATE PDPCONTEXT REQUEST) message, carry session management and keep out of the way timer value (SM back-offtimervalue).
Double priority level terminal
Third generation partner program (3rd Generation Partnership Project, 3GPP) low priority access (low priority access) terminal has been discussed and has been initiated the problem that normal priority accesses (normal priorityaccess), proposition is configured to Non-Access Stratum signaling low priority (NAS signalling low priority) terminal can be configured to cover Non-Access Stratum signaling low priority (override the NAS signallinglow priority indicator) simultaneously, when this class double priority level terminal connects at the PDN that sets up non-low access priority, perhaps when the session management procedure of carrying out with the PDN join dependency of the non-low access priority of having set up, the session management request message that sends can be with low access priority indication.
This class double priority level terminal is when receiving that session management that network side issues is kept out of the way timer value, can keep out of the way timer value according to this session management and start session management and keep out of the way timer, this session management is kept out of the way the access priority that access priority corresponding to timer is the corresponding session management request message of initiating for terminal.After the session management that has started the session management request of low access priority indication for band was kept out of the way timer, UE still can initiate not to be with the session management request of low access priority indication.The existing protocol concrete regulation is as follows:
When connecting foundation request (PDNCONNECTIVITY REQUEST) message because carry the PDN of low access priority indication, when bearing resource is revised request (BEARER RESOURCEMODIFICATION REQUEST) message or bearing resource and is distributed request (BEARER RESOURCEALLOCATION REQUEST) message to be started the session management relevant with APN with No. 26 cause values " inadequate resource (insufficientresource) " refusal and keep out of the way timer T3396 by network, based on the upper strata request, UE can be initiated to and not connecting with the PDN of low access priority indication of identical APN set up request message or initiate BEARER RESOURCE MODIFICATION REQUEST or BEARER RESOURCEALLOCATION REQUEST message with the PDN join dependency of not indicating with low access priority of having set up.
If this class double priority level starting terminal keep out of the way timer for the session management of the session management request message that carries non-low access priority indication, UE can not initiate any non-emergent (emergency) business, the session management request that non-Priority Service (priority service) is professional.
In the existing protocol, double priority level terminal is after the startup session management is kept out of the way timer, receive that again when new session management was kept out of the way timer value, the session management that need to stop to move was kept out of the way timer, then keep out of the way timer value with the session management of receiving and start session management and keep out of the way timer.
In the existing protocol, if double priority level terminal is received again the following non-DEACTIVATE EPS BEARER CONTEXT REQUEST/DEACTIVATE PDP CONTEXT REQUEST message that network is sent: 1 after the startup session management is kept out of the way timer, activate the acquiescence evolved packet system bearer context request/special-purpose evolved packet system bearer context request of activation/modification evolved packet system bearer context request (ACTIVATE DEFAULT EPS BEARER CONTEXTREQUEST/ACTIVATE DEDICATED EPS BEARER CONTEXTREQUEST/MODIFY EPS BEARER CONTEXT REQUEST); 2, request packet data protocol context activation/request second packet data protocol context activation/modification packet data protocol context request (REQUEST PDP CONTEXT ACTIVATION/REQUEST SECONDARYPDP CONTEXT ACTIVATION/MODIFY PDP CONTEXT REQUEST).Connect if terminal is set up the PDN of the different access priorities of identical APN simultaneously, then the terminal session management that can not stop to move is kept out of the way timer.
No matter be that terminal is received when new session management is kept out of the way timer value, the session management that stops to move is kept out of the way timer; Or when terminal was received non-PDN deexcitation session management request message, the session management that can not stop to move was kept out of the way timer.All may cause terminal to keep out of the way Timer Controlling according to session management and whether initiate the process of corresponding session management request and the requirement of network side is not inconsistent, the performance of reduction system operation to network side.

Embodiment
Control method and corresponding terminal that the embodiment of the invention provides a kind of session management to keep out of the way timer.Than prior art, the technical scheme that the embodiment of the invention provides is being carried out out of service or is being continued before the Run Sessions management keeps out of the way the action of timer, increased according to the session management for same APN that is moving and kept out of the way the access priority of Packet Data Network's connection corresponding to priority corresponding to timer and this session management request message/this session management request message, determine whether to carry out the step of corresponding actions, so that continuing to move this session management according to the result who determines keeps out of the way timer or stops this session management and keep out of the way timer, can so that terminal is kept out of the way the requirement that process that whether Timer Controlling initiate from corresponding session management request to network side more meets network side according to session management, improve the performance of system's operation.
Below in conjunction with accompanying drawing, the technical scheme that the embodiment of the invention is provided is elaborated.
The control method that a kind of session management that the embodiment of the invention provides is kept out of the way timer, its implementation specifically comprise following operation as shown in Figure 1:
Wherein, for the session management request message of deexcitation bearer context, its for specific APN refer to occur congested APN or the APN corresponding with the PGW that resets.For the session management request message of non-deexcitation bearer context, its for specific APN refer to the congested APN that alleviates or eliminate.
Wherein, the access priority that SM back-off timer is corresponding refers to the be under an embargo access priority of the session management request message of initiating of this UE.For example, the SM back-off timer of current operation is: before the step 100, network equipment refuse that this UE initiates with the session management request message of low access priority indication the time, the SM back-offtimer that this UE starts according to the SM back-off timer value in the refuse information.So, at this SM back-off timer run duration, UE is under an embargo and initiates the session management request message of the low access priority indication of band, and the access priority corresponding to SM back-off timer of current operation is exactly low access priority.
In the embodiment of the invention, above-mentioned session management request message for PDN connect, refer to that the PDN of the operation effect of this session management request message connects.The session management request message for the access priority that connects of PDN, when referring to that this UE initiates to set up this PDN and connects, the PDN that sends connects the access priority of setting up request message.
As described in the background art, in the existing protocol, double priority level terminal is after starting SM back-off timer, when receiving again new SM back-off timer value, then the SM back-off timer that need to stop to move starts SM back-off timer with the SM back-off timer value that receives.Yet consider following scene:
1, network side generation packet data network gateway reset (PGW recovery), network equipment needs deexcitation all PDNs relevant with congested APN occurs to connect and issues SM back-off timer value, UE may receive first that the PDN that the PDN of non-low access priority connects connects the deexcitation request, therefore started for the SM back-off timer that congested APN and corresponding non-low access priority occur, received that then the PDN of the PDN connection of low access priority connects the deexcitation request.
2, UE has set up the PDN connection of low access priority, the APN of network side and this PDN join dependency occurs congested, but network equipment is not initiated PDN and is connected deactivation process, UE is initiated to the PDN connection of not indicating with low priority of identical APN and does not set up request message, the request of network equipment refusal UE, and issue SM back-off timer value.UE starts for the SM back-off timer that congested APN and corresponding non-low access priority occur, this APN Persistent Congestion in the network, PGWrecovery occurs, and all relevant PDN of congested APN occur and connect in the network equipment deexcitation, and issue SM back-off timer value.
For above-mentioned scene, the problem that prior art exists is: network side occurs before or after the PGW recovery, and UE has started SM back-off timer, and the access priority that this SM back-off timer is corresponding is normal access priority.Then, UE receives again the session management request message that the low access priority PDN of deexcitation connects, UE starts SM back-off timer and should not restart according to the SM back-off timer value of newly receiving, otherwise the follow-up session management request of not indicating with low access priority to identical APN can not be prevented from, and increases the network signal burden.Should be pointed out that this problem that exists in the prior art is not limited only to above-mentioned scene.After starting SM back-off timer, again receive the scene of new SM back-off timer value for same APN for other double priority level terminals, still there are the problems referred to above in prior art.
The method that adopts the embodiment of the invention to provide can solve the problems of the technologies described above.Accordingly, after starting SM back-off timer, when receiving again new SM back-off timer value for same APN, if the access priority corresponding to SM back-off timer of operation is not higher than the access priority that PDN corresponding to session management request message of the above-mentioned new SM back-off timer value of carrying of receiving connects
The SM back-off timer that then should stop to move, and restart above-mentioned new SM back-off timer value according to above-mentioned new SM back-off timervalue; If the access priority corresponding to SM back-off timer of operation is higher than the access priority that PDN corresponding to session management request message of the above-mentioned new SM back-off timer value of carrying of receiving connects, then should ignore above-mentioned new SM back-off timervalue, continue operation SM back-off timer.Accordingly, the specific implementation of above-mentioned steps 110 can be: judge with the access priority that PDN corresponding to the above-mentioned session management request message that is connected SM back-off timervalue connects according to the access priority that the SM back-off timer of operation is corresponding: if the access priority corresponding to SM back-off timer of operation is higher than the access priority that this PDN connects, determine to continue this SM back-off timer of operation; If the access priority corresponding to SM back-off timer of operation is not higher than the access priority that this PDN connects, determine to stop this SM back-off timer of current operation.If determine this SM back-off timer out of service, restart SM back-off timer according to the SM back-off timer value that carries in the session management request message.
Suppose that double priority level terminal sets up simultaneously that the PDN of the low access priority of identical APN connects and the PDN connection of the access priority of being connected, because APN is identical, network side is that two PDN that UE sets up connect all towards identical PGW, take above-mentioned scene 1 as example, the method that the embodiment of the invention provides specifically comprises following operation as shown in Figure 2:
Network side sends respectively for low access priority PDN to UE and connects and for the deexcitation PDN connection request message of normal access priority, and carries SMback-off timer value in each deexcitation PDN connection request message.
Wherein, deexcitation PDN connection request message is the session management request message that carries SM back-off timer value.This deexcitation PDN connection request message can but to be not limited only to be following message: DEACTIVATE EPS BEARER CONTEXT REQUEST/DEACTIVATE PDPCONTEXT REQUEST.
Step 200, UE receive first the deexcitation PDN connection request message for the PDN connection of normal access priority, and according to the SM back-off timer value that carries in the request, start SM back-off timer.
At this SM back-off timer run duration, UE forbids initiating the session management request message of low access priority and the session management request message of normal access priority to network side.
Step 210, UE receive again the deexcitation PDN connection request message for the PDN connection of low access priority.
Step 220, UE judge the access priority corresponding to SM back-off timer of operation be higher than deexcitation PDN connection request message for the access priority that connects of PDN, determine to continue operation SM back-off timer.
Step 230, UE continue operation SM back-off timer, ignore the SM back-off timervalue that receives.
Suppose that double priority level terminal sets up simultaneously that the PDN of the low access priority of identical APN connects and the PDN connection of the access priority of being connected, because APN is identical, network side is that two PDN that UE sets up connect all towards identical PGW, take above-mentioned scene 1 as example, the method that the embodiment of the invention provides specifically comprises following operation as shown in Figure 3:
Network side sends respectively for low access priority PDN to UE and connects and for the deexcitation PDN connection request message of normal access priority, and carries SMback-off timer value in each deexcitation PDN connection request message.
Wherein, deexcitation PDN connection request message is the session management request message that carries SM back-off timer value.
Step 300, UE receive first the deexcitation PDN connection request message for the PDN connection of low access priority, and according to the SM back-off timer value that carries in the request, start SM back-off timer.
At this SM back-off timer run duration, UE forbids initiating to network side the session management request message of low access priority, but can initiate to network side the session management request message of normal access priority.
Step 310, UE receive again the deexcitation PDN connection request message for the PDN connection of normal access priority.
Step 320, UE judge the access priority corresponding to SM back-off timer of operation be lower than deexcitation PDN connection request message for the access priority that connects of PDN, determine SM back-off timer out of service.
Step 330, UE SM back-off out of service timer are restarted SM back-off timer according to the SM back-off timervalue that receives.
SM back-off timer run duration after restarting, UE are forbidden initiating the session management request message of low access priority and the session management request message of normal access priority to network side.
Suppose the PDN connection that double priority level terminal is set up to be had to the low access priority of certain APN, take above-mentioned scene 2 as example, the method that the embodiment of the invention provides specifically comprises following operation as shown in Figure 4:
Because it is congested that corresponding APN occurs, the request of network equipment refusal is returned refuse information to UE, carries SM back-off timer value in this refuse information.
At this SM back-off timer run duration, UE forbids initiating the session management request message of low access priority and the session management request message of normal access priority to network side.
MME needs deletion all PDNs relevant with this APN to connect according to operation, (OAM) request that administers and maintains.Perhaps recovery/restart occurs in the PGW relevant with this APN, need deletion all PDNs relevant with this APN to connect, then the network measurement equipment is initiated PDN connection deactivation process, send the deexcitation PDN connection request message that connects for the PDN that hangs down access priority to UE, and in deexcitation PDN request message, carry SM back-off timer value.
Wherein, deexcitation PDN connection request message is the session management request message that carries SM back-off timer value.
Should be pointed out that among Fig. 2, Fig. 3 and the embodiment shown in Figure 4, all describe as an example of double priority level terminal example, but the method that the embodiment of the invention provides also can be applied to the multipriority terminal.
As stated in the Background Art, in the existing protocol, if double priority level terminal is received again the following non-deexcitation loading context information (being non-DEACTIVATE EPSBEARER CONTEXT REQUEST/DEACTIVATE PDP CONTEXT REQUEST message) that network is sent: 1, ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST/ACTIVATEDEDICATED EPS BEARER CONTEXT REQUEST/MODIFY EPS BEARERCONTEXT REQUEST after starting SM back-off timer; 2, REQUEST PDP CONTEXT ACTIVATION/REQUESTSECONDARY PDP CONTEXT ACTIVATION/MODIFY PDP CONTEXTREQUEST.If setting up the PDN of the different access priorities of identical APN simultaneously, terminal connects, then the terminal SM back-off timer that can not stop to move.Yet consider following scene:
3, on the terminal there be for the SM back-off timer that congested APN and corresponding low access priority occur operation, the session management request message (being the session management request message that non-deexcitation PDN connects) for the non-deexcitation EPS bearer of this APN of receiving that network equipment sends, and the access priority that the corresponding PDN of this session management request message connects is low access priority.
4, operation has the SM back-off timer that connects for the PDN that congested APN and corresponding normal access priority occur on the terminal, the session management request message for the non-deexcitation EPSbearer of this APN of receiving that network equipment sends.
For above-mentioned scene, the problem that prior art exists is: when the APN in the network is congested when alleviating, network may be initiated the session management request of non-deexcitation bearer context, according to existing protocol, terminal can not stop the SM back-off timer of current operation, causes the behavior of terminal not meet requirement according to network.
The method that adopts the embodiment of the invention to provide can solve the problems of the technologies described above.Accordingly, after starting SM back-off timer, when receiving the session management request message of non-deexcitation bearer context for same APN, if the access priority corresponding to SM back-off timer of operation is lower than the access priority that PDN corresponding to the session management request message of the non-deexcitation bearer context of receiving connects, then should continue to move SM back-off timer; If the access priority corresponding to SM back-off timer of operation is not higher than the access priority that PDN corresponding to the session management request message of the non-deexcitation bearer context of receiving connects, the SM back-off timer that then should stop to move.Accordingly, the specific implementation of above-mentioned steps 110 can be: according to the access priority corresponding to SM back-off timer of operation be connected the access priority that the PDN corresponding to above-mentioned session management request message of deexcitation bearer context connect and judge: if the access priority corresponding to SM back-off timer of operation is lower than the access priority that this PDN connects, determine to continue this SM back-off timer of operation; If the access priority corresponding to SM back-off timer of operation is not less than the access priority that this PDN connects, determine to stop this SMback-off timer of current operation.
Take double priority level terminal as example, 110 pairs of specific implementations of above-mentioned steps can be: according to the access priority corresponding to SM back-off timer of operation be connected the access priority that the PDN corresponding to above-mentioned session management request message of deexcitation bearer context connect and judge:
If the access priority that the SM back-off timer of operation is corresponding is low access priority, the access priority that the PDN that above-mentioned session management request message is corresponding connects is normal access priority, determines to continue this SM back-off timer of operation;
If the access priority corresponding to SM back-off timer of operation is normal access priority, the access priority that the PDN that above-mentioned session management request message is corresponding connects is low access priority, determines to stop this SM back-off timer of current operation.
Especially, for double priority level terminal, if the access priority corresponding to SM back-off timer of current operation is non-low access priority (being normal access priority), the access priority that SM back-off timer is corresponding so is not less than the access priority that PDN corresponding to the session management request message of non-deexcitation bearer context connects certainly.Then the specific implementation of above-mentioned steps 110 can be: according to the non-low access priority corresponding to SM back-off timer of operation and the above-mentioned session management request message of non-deexcitation bearer context, determine this SM back-off timer out of service.
Take above-mentioned scene 3 as example, the method that the double priority level terminal applies embodiment of the invention provides specifically comprises following operation as shown in Figure 5:
The session management request message for the non-deexcitation EPS bearer of same APN that step 500, UE receive that network equipment sends.
The access priority that the PDN that the access priority that the SM back-off timer that step 510, UE relatively move is corresponding is corresponding with the session management request message connects.
If the session management request message for be that the PDN of low access priority connects, then the access priority corresponding to SMback-off timer of operation is lower than the access priority that PDN corresponding to session management request message connects, and execution in step 520, UE determine to continue operation SM back-off timer.
If the session management request message for be that the PDN of normal access priority connects, then the access priority corresponding to SM back-off timer of operation is not less than the access priority that PDN corresponding to session management request message connects, and execution in step 540, UE determine SM back-off timer out of service.
Take above-mentioned scene 4 as example, for double priority level terminal, the method that the embodiment of the invention provides specifically comprises following operation as shown in Figure 6:
The session management request message for the non-deexcitation bearer context of specific APN that step 600, UE receive that network equipment sends (being the session management request message of above-mentioned non-deexcitation EPS bearer).
Step 610, this UE according to current operation for the SM back-off timer of specific APN corresponding normal access priority and this session management request message, determine to stop the SM back-off timer of current operation.
Because the access priority corresponding to SM back-off timer of current operation is normal access priority, certainly be not less than the access priority that PDN corresponding to session management request message connects, so UE determines SM back-off timer out of service.At definite SM back-off timer out of service, UE SM back-off out of service timer.
Should be pointed out that in the above-described embodiment for scene 3 and 4, all describe as an example of double priority level terminal example, but the method that the embodiment of the invention provides also can be applied to the multipriority terminal.
As shown in Figure 7, be that the method that the application embodiment of the invention provides is carried out the specific implementation process that SM back-off timer controls, it specifically comprises following operation:
Step 710, UE judge whether this session management request message is the session management request message of non-deexcitation bearer context, if so, and execution in step 720, otherwise, execution in step 750.
Based on the inventive concept same with inventive embodiments, the embodiment of the invention also provides a kind of terminal, its structure as shown in Figure 8, the specific implementation structure is as follows:
The first message sink unit 801 is used for receiving the session management request message for the particular access point title;
