Description
Technical field
The terminal when the present invention relates in packet switching (Packet Switched) business cell update take place and the abnormality eliminating method of network, relate in particular to when in the packet switching service cell update taking place, under the situation that the PS service exception interrupts, the processing method of terminal and network.
Background technology
Subscriber equipment (User Equipment, UE) at packet switching (the Packet Switched that keeps stream (streaming) or session (conversational) type, PS) cell update (CellUpdate) takes place between service period, radio network controller (Radio Network Controller, RNC) may initiate Radio Resource control (the Radio Resource Control of " direct signaling connection reconstruction (directed signaling connection re-establishment) " reason, RRC) connect release, trigger subscriber equipment and initiate Routing Area Update (Routing Area Update in new sub-district, RAU) process and GPRS supporting node (Serving GPRS Support Node, SGSN) mutual, and (RadioAccess Bearer is RAB) with the recovery packet switching service to rebuild RAB in new sub-district.
Between the PS service period of stream or conversation type, because the deterioration of wireless environment quality, terminal may detect with network and lose synchronously, and Radio Link Failure (radio link failure) takes place.Perhaps owing to the deterioration of wireless environment quality, (Signalling Radio Bearer SRB) goes up the generation Radio Link and controls irrecoverable property mistake (RLC unrecoverable error) to cause a certain Signaling Radio Bearer of terminal.According to the prior protocols requirement, when terminal finds that wireless coverage is lost, should be according to GPRS23.060, following processing is carried out in the description of Sec 9.2.3.5 in the V720 agreement: (PDP Context Deactivation) is preceding in the PDP deexcitation, if terminal is because bottom link reason has discharged RAB, it is 0 that maximal bit (bit) speed should be set earlier, initiates PDP and revise (PDP context modification) process behind link-recovery, in order to recover original RAB.In addition, terminal this moment will re-selecting cell according to protocol requirement, is carrying out cell updating course on new sub-district.
As shown in Figure 1, if SRNC this moment also detects with the wireless connections of terminal lose, SRNC can be according to 23.060, and " IU discharges (IU Release) " process is initiated in the description of Sec 9.2.3.4 among the V720.Before the PDP deexcitation, if SGSN receive RNC's " IU release ", it is 0 that maximum bit rate then should be set, and does not initiatively rebuild RAB in the follow-up business request process.
As shown in Figure 2, if SRNC also detected with the wireless connections of terminal and lost this moment, SRNC can be according to 23.060, and the description of Sec 9.2.3.5 among the V720 is initiated " RAB discharges (RAB Release) " and crossed range request release RAB under the situation that does not discharge the IU connection.Before the PDP deexcitation, SGSN receives " the RAB release " of RNC, and it is 0 that maximum bit rate should be set, and does not initiatively rebuild RAB in the follow-up business request process.
On the other hand, if terminal is carried out the sub-district gravity treatment because Radio Link Failure (Radio Link Failure) or Radio Link are controlled irrecoverable property mistake (RLC unrecoverable error), the words that sub-district of selecting and former sub-district are not subordinated to same RNC, when DRNC receives cell update message, owing to there is not the connection of Iur interface in the existing network between the RNC, in the time of can't knowing the relevant information of terminal, DRNC illustrated in figures 1 and 2 uses the reason notice UE of " direct signaling connection reconstruction (directed signaling connectionre-establishment) " to carry out RRC connection release.When UE receives the RRC connection release message of this reason, initiate the RAU process earlier, and then initiate the service request process and rebuild former RAB.
When finishing (Routing area update complete) message when SGSN receives the Routing Area Update of terminal, find that maximum bit rate is 0, then initiatively do not rebuild RAB.When SGSN receives that the PDP of terminal revises request (Modify PDP Context Request) message, maximum bit rate (former maximum bit rate) and local (bit rate is 0) of storing of finding this message are inconsistent, then initiate RAB and revise (RAB modification) process, recover the maximum bit rate of terminal.
Finish the process of reconstruction of PS business by Routing Area Update (Routing area update) process and PDP Context Modification process, make that the PS business recovery is normal.
Yet, existing processing mode might occur unusually, as shown in Figure 3, when terminal when new RNC initiates cell update, but former RNC may also not detect out of touch or detect with terminal is out of touch and also send IU to SGSN and discharge or the RAB release message with terminal, like this when SGSN abides by the prior protocols realization fully, when receiving Routing Area Update when it and finish (Routing area update complete) message, find that Qos does not change, be that maximum bit rate is not set to 0, can carry out the RAB process of reconstruction immediately.And PDP modification request (Modify PDP context Request) message of receiving terminal subsequently finds that maximum bit rate does not change, do not respond then that (this is because agreement not have to receive under the situation of variation the concrete behavior of SGSN behind the Modify PDP context Request of terminal at maximum bit rate, present SGSN does not often respond), to cause terminal to send Modify PDP contextrequest message like this above after the maximum times, initiate PDP deexcitation request (Deactivate PDP ContextRequest) process, thereby cause the abnormal terminals of PS business.

Embodiment
The invention will be further described below in conjunction with drawings and Examples.
The invention provides two kinds of embodiment and solve the problems of the prior art, Fig. 4 shows in the PS business of the present invention the flow process of first embodiment of the abnormality eliminating method of terminal when cell update takes place and network.Seeing also Fig. 4, is the detailed description to each step of first embodiment of abnormality eliminating method below.
At first, between the PS service period of stream or conversation type, because the deterioration of wireless environment quality, terminal may detect with network and lose synchronously, and Radio Link Failure (radio link failure) takes place.Perhaps owing to the deterioration of wireless environment quality, (Signalling RadioBearer SRB) goes up the generation Radio Link and controls irrecoverable property mistake (RLC unrecoverable error) to cause a certain Signaling Radio Bearer of terminal.(PDP Context Deactivation) is preceding in the PDP deexcitation, if terminal is because bottom link reason has discharged RAB, it is 0 that maximal bit (bit) speed should be set earlier.In addition, terminal this moment will re-selecting cell according to protocol requirement, is carrying out cell updating course on new sub-district.
Abnormal conditions have been run in the present embodiment, be terminal when new RNC initiates cell update (Cell Update), out of touch or detect with terminal is out of touch and send to SGSN also that IU discharges (IU Release) or RAB discharges (RAB Release) message but former RNC does not also detect with terminal.
Terminal and DRNC (Drift Radio Network Controller, floating radio network controller) carry out RRC between again and connect release (RRC Connection Release), the reason notice terminal of DRNC use direct signaling connection reconstruction (directed signaling connection re-establishment) is carried out the RRC connection and is discharged.
Then, carry out the RRC connection reconstruction between terminal and the DRNC.The RRC connection reconstruction was broadly divided into for three steps: terminal is sent RRC connection request (RRC Connection Request) message to DRNC, DRNC sends RRC to terminal and connects foundation (RRC Connection Setup) message, and terminal reports RRC to set up to DRNC and finishes (RRC Connection Setup complete) message.
Then, terminal is initiatively initiated the Routing Area Update process with SGSN, be broadly divided into for three steps: terminal is sent Routing Area Update request (Routing area update request) message to SGSN, SGSN sends Routing Area Update to terminal and receives (Routing area update accept) message, and terminal reports Routing Area Update to finish (Routing area update complete) message to SGSN.
After SGSN receives that the Routing Area Update of terminal is finished message, find that local maximal bit (bit) speed is not 0, still directly carry out RAB and rebuild (Radio Access Bearer Setup, RAB SETUP) process.
SGSN receives that the PDP of terminal revises request (Modify PDP context request) message, if and the former maximum bit rate in the message is identical with local maximum bit rate, then SGSN no longer carries out the RAB process of reconstruction, SGSN does not carry out upgrading (Update PDP Context Request and Update PDPContext Response) process with the PDP of GGSN, but directly the PDP of response terminal revises reception (Modify PDP ContextAccept) message.
Terminal is received after PDP revises reception message and is recovered former maximum bit rate, finishes the recovery process of packet switching service.
From said process as can be seen, present embodiment does not have under the situation of variation by clearly retraining SGSN at Qos, after receiving the Modify PDP context Request message of terminal, do not carry out Update PDPContext process with GGSN, directly the Modify PDP Context Accept message of response terminal is recovered the professional purpose of PS (packet switching) thereby reach.
Fig. 5 shows in the PS business of the present invention the flow process of second embodiment of the abnormality eliminating method of terminal when cell update takes place and network.Seeing also Fig. 4, is the detailed description to each step of second embodiment of abnormality eliminating method below.
At first, between the PS service period of stream or conversation type, because the deterioration of wireless environment quality, terminal may detect with network and lose synchronously, and Radio Link Failure (radio link failure) takes place.Perhaps owing to the deterioration of wireless environment quality, (Signalling RadioBearer SRB) goes up the generation Radio Link and controls irrecoverable property mistake (RLC unrecoverable error) to cause a certain Signaling Radio Bearer of terminal.(PDP Context Deactivation) is preceding in the PDP deexcitation, if terminal is because bottom link reason has discharged RAB, it is 0 that maximal bit (bit) speed should be set earlier.In addition, terminal this moment will re-selecting cell according to protocol requirement, is carrying out cell updating course on new sub-district.
Abnormal conditions have been run in the present embodiment, be terminal when new RNC initiates cell update (Cell Update), out of touch or detect with terminal is out of touch and send to SGSN also that IU discharges (IU Release) or RAB discharges (RAB Release) message but former RNC does not also detect with terminal.
Carry out RRC between terminal and the DRNC again and connect release (RRC Connection Release), the reason notice terminal of DRNC use direct signaling connection reconstruction (directed signaling connection re-establishment) is carried out the RRC connection and is discharged.
Then, carry out the RRC connection reconstruction between terminal and the DRNC.The RRC connection reconstruction was broadly divided into for three steps: terminal is sent RRC connection request (RRC Connection Request) message to DRNC, DRNC sends RRC to terminal and connects foundation (RRC Connection Setup) message, and terminal reports RRC to set up to DRNC and finishes (RRC Connection Setup complete) message.
Then, terminal is initiatively initiated the Routing Area Update process with SGSN, be broadly divided into for three steps: terminal is sent Routing Area Update request (Routing area update request) message to SGSN, SGSN sends Routing Area Update to terminal and receives (Routing area update accept) message, and terminal reports Routing Area Update to finish (Routing area update complete) message to SGSN.
After SGSN receives that the Routing Area Update of terminal is finished message, find that local maximal bit (bit) speed is not 0, still directly carry out RAB and rebuild (Radio Access Bearer Setup, RAB SETUP) process.
SGSN receives that the PDP of terminal revises request (Modify PDP context request) message, if the former maximum bit rate in the message is identical with local maximum bit rate, then SGSN does not carry out upgrading (Update PDP Context Request and Update PDP Context Response) process with the PDP of GGSN, and also the PDP of response terminal does not revise and receives (Modify PDP Context Accept) message.
Receiving terminal if RAB is rebuilding or rebuilding success, then stopped current PDP and revises request process before PDP revises request transmission arrival maximum number of times of transmission, directly recovered maximum bit rate, thereby finished the recovery process of packet switching service.Revising request at PDP sends and reaches in the maximum number of times of transmission, if RAB is rebuilding or is rebuilding success, then no longer carry out PDP deexcitation (PDP ContextDeactivation) process, directly recover maximum bit rate, thereby finish the recovery process of packet switching service.
For the step of the preceding paragraph, two kinds of concrete execution modes can be arranged.First kind is after terminal is finished the RAB process of reconstruction, finds to have ongoing PDP to revise request process, then stops this request process, directly recovers maximum bit rate, thereby finishes the recovery process of packet switching service.In this enforcement means, it successfully is a trigger point that RAB rebuilds.
Second kind is predetermined timing device T3381 in introducing agreement.Timer T3381 role is when timing arrives preset value PDP to be revised request to send number of times increase by 1.The second way is different from first kind of mode part and is initiatively to go to judge whether RAB rebuilds or rebuild.Specifically, the timer T3381 that receives message as terminal wait PDP is overtime, and PDP revises when asking to send no show maximum number of times of transmission still, go initiatively to judge whether RAB is rebuilding or rebuilding success, then stop current PDP in this way and revise request process, directly recover maximum bit rate, thereby finish the recovery process of packet switching service; The timer T3381 that revises reception message when the terminal wait block data protocol context is overtime, and PDP revises request and sends when having arrived maximum number of times of transmission, find that RAB is rebuilding or rebuilding success, then no longer carry out PDP deactivation process (PDP Context Deactivation), directly recover maximum bit rate, thereby finish the recovery process of packet switching service.
From said process as can be seen, in the present embodiment, after terminal is sent Modify PDP contextrequest message, if finding RAB normally sets up, then stop current Modify PDP context process, and recover maximum bit rate immediately, thereby reach the purpose of recovering the PS business.
The foregoing description provides to those of ordinary skills and realizes or use of the present invention; those of ordinary skills can be under the situation that does not break away from invention thought of the present invention; the foregoing description is made various modifications or variation; thereby protection scope of the present invention do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
