Below in conjunction with concrete application scenarios, technical solution of the present invention is described in detail.
Embodiment three, and a kind of terminal spans into the method that network element switches, and signaling process comprises as shown in Figure 4:
401, target side access network element sendaisle conversion request is given mobile management network element, and notice mobile management network element UE is at the access network element of target side; Mobile management network element decision Serving GW switches.
402, mobile management network element sends and creates the Serving GW of carrying request to target side, and bearing resource is set up in request.
The Serving GW of 403a, target side sends more new bearer request to PDN GW.
403b, PDN GW return new bearer more and respond Serving GW to target side.
404, the Serving GW of target side returns and creates the carrying response to mobile management network element.Downlink data channel is got through.
405, mobile management network element sendaisle conversion request acknowledge message is given the target side access network element.The upstream data passage is got through.
406, target side access network element transmission release message related to resources is gone into network element to former side joint.Notify former side joint to go into network element and discharge resource.
407a, mobile management network element send the deleting bearing request to former side Serving GW, delete the bearing resource about this UE of former side Serving GW.
407b, former side Serving GW return the deleting bearing response message and give mobile management network element, and indication discharges about this UE bearing resource.
408a, mobile management network element send the deexcitation request to described terminal ISR;
408b, described terminal are returned the response message that the ISR deexcitation is accepted to described mobile management network element.
In the present embodiment, on the basis of prior art flow process, increase by two NAS signalings:
ISR deexcitation request among the 408a and the ISR deexcitation acceptance response among the 408b.
After step 407b, the mobile management network element of network side directly sends the 408a step to UE: ISR deexcitation request.After UE receives this message, carry out the ISR deexcitation, after finishing, UE returns to the network side mobile management network element 408b step then: the ISR deexcitation is accepted.
Above-mentioned schematic flow sheet is applicable to that promptly the EUTRAN network also is applicable to the GEUTRAN/UTRAN network, and when this flow process was applicable to different networks, the individual message title is difference to some extent, but does not influence its mutual sequential and effect.Wherein:
When the EUTRAN network, source access network element and target access network unit are eNodeB, and mobile management network element is MME.
When the GEUTRAN network, source access network element and target access network unit are BSS, and mobile management network element is SGSN.
When the UTRAN network, source access network element and target access network unit are RNC, and mobile management network element is SGSN.
Be understandable that, because switching has taken place in access network element, may cause the tracking area at the present place of UE or route district not in the tabulation in the tracking area of UE inside or route district, after switching was finished, UE is initiating updating of tracking area or Routing Area Update flow process initiatively like this.In this case, the mobile management network element of network side can be accepted message or route district at tracing section updating and follows the tracks of and accept notice UE ISR deexcitation in the message.
After step 407b, switching has taken place in access network element, but the tracking area at the present place of UE or route district also within the tabulation in the tracking area of UE inside or route district, Idle state UE is initiatively initiating updating of tracking area or Routing Area Update flow process just.In this case, after switching was finished, the mobile management network element of network side need send the 408a step to UE: ISR deexcitation request.After UE receives this message, carry out the ISR deexcitation, after finishing, return to the network side mobile management network element 408b step then: the ISR deexcitation is accepted.Concrete solution: can one timer be set in network side mobile management network element inside, after the step 407b, timer starts, if before timer is not overtime, the mobile management network element of network side has received tracing section updating request or the Routing Area Update request that UE sends, so the mobile management network element of network side this timer that will reset.And the mobile management network element of network side is accepted message or Routing Area Update at tracing section updating and is accepted notice UE ISR mechanism deexcitation in the message.If timer expiry, the mobile management network element of network side need send the 408a step to UE so: ISR deexcitation request.After UE receives this message, carry out the ISR deexcitation, after finishing, UE returns to the network side mobile management network element 408b step then: the ISR deexcitation is accepted.
Be understandable that, in the embodiment of the invention, can also do not adopt above-mentioned timer scheme, reach the effect of same saving signaling, that is:
The mobile management network element of network side judges that by the current position information of the terminal that the target side access network element reports whether UE is at present in its route district or inside the tracking area tabulation.If the present positional information of UE is or not its route district or tracking area tabulation the inside, initiatively initiating updating of tracking area or Routing Area Update flow process of UE so.In this case, the mobile management network element of network side can be accepted message or route district at tracing section updating and follows the tracks of and accept notice UE ISR deexcitation in the message.。If UE is also in its route district or inside the tracking area tabulation, the mobile management network element of network side need send the 8a step to UE: ISR deexcitation request.After UE receives this message, carry out the ISR deexcitation, after finishing, return to the network side mobile management network element 8b step then: the ISR deexcitation is accepted.
Be understandable that in step 401, the mobile management network element that passage conversion request message is given network side can be sent out by target access network unit, in this message, the target side access network element can report the positional information of UE the mobile management network element of network side.
Mode for the deexcitation of mobile management network element notice terminal can also take other modes to realize, for example: be transformed into by connected state in terminal and adopt release command to notify described terminal ISR deexcitation in the dispose procedure of Idle state by described second access network element, signaling process comprises as shown in Figure 5:
501, the target side access network element sends S1 release request message to mobile management network element.

503, Serving GW returns the bearer update response message and gives mobile management network element.
504, mobile management network element sends the S1 release command message to the target side access network element.In this message, can increase cell indication ISR deexcitation.Concrete settling mode can be: increase cell in this message: ISR deactive.When this cell value was 1, this cell was effective, and when this cell value was 0, this cell was invalid.
505, the target side access network element sends to UE and discharges the message that RRC connects.The access network element of target side is when receiving for the 4th step message the time, and to the newly-increased cell of the inside: ISR deactive does not deal with, and this cell is included in the 5th message, directly sends to UE.
506, UE sends out and discharges RRC connection acknowledge message to the target side access network element.After UE received the 5th message, judge newly-increased cell in this message: whether ISR deactive was effective.If effectively, UE is with deexcitation ISR mechanism so, if invalid, UE will not do any processing.Concrete processing mode: in this message, increase cell: ISR deactive Ack.If the 5th ISR deactive cell is effective in the message, UE deexcitation ISR mechanism so, and will increase cell newly: ISR deactive Ack is changed to effectively.If the 5th ISR deactive cell is invalid in the message, so newly-increased cell: it is invalid that ISR deactive Ack is changed to.When this cell value was 1, this cell was effective, and when this cell value was 0, this cell was invalid.
507, target side access network element transmission S1 discharges and finishes to mobile management network element.The access network element of target side is when receiving for the 6th step message the time, and to the newly-increased cell of the inside: ISR deactive Ack does not deal with, and this cell is included in the 7th message, directly sends to mobile management network element.
