In order to improve the resource utilization of the network equipment, make correctly and efficiently to complete load bearing process after user contracting data changes, the embodiment of the present invention processing method to carrying is after the insertion or deletion flow process of subscription data, such as, at HSS after MME and/or SGSN initiates the insertion flow process of subscription data, if the user contracting data of record changes in mobile management device, first this mobile management device determines the existence of the subscriber equipment of correspondence, determines whether initiate the amendment of carrying or delete flow process according to the existence of this subscriber equipment.
The method that the embodiment of the present invention provides is possible not only to be applicable to single wireless access technology system, such as, 2G or 3G system, System Architecture Evolution (SAE, SystemArchitechureEvolution) system；And go for the applied environment that multiple radio access technology system coexists, and such as, SAE system and the applied environment of 2G coexistence of systems, SAE system and the applied environment etc. of 3G coexistence of systems.
With instantiation, the processing method situation under different application environment of carrying is illustrated by the present invention respectively below.
With reference to Fig. 1, it is the present invention flow chart to the processing method first embodiment of carrying, comprises the following steps:
101.HSS sends and inserts subscription data message to MME or SGSN；
102.MME or SGSN updates the subscription data preserved, and replys to HSS and inserts subscription data confirmation message；
103.MME or SGSN judges whether subscriber equipment (UE, UserEquipment) has signaling to be connected with oneself；
By following two method, MME or SGSN can judge whether UE has signaling to be connected with oneself:
The index that in the user's context that 1.MME or SGSN inquiry preserves, signaling connects the most effectively judges, if index is effectively, then explanation UE has signaling to be connected with oneself；
In the user's context that 2.MME or SGSN inquiry preserves, user's mobile management state is Idle state or connected state judges.If User Status is connected state, then UE is described and oneself has signaling to connect.
After 104.MME or SGSN determines that UE is in connection status, initiate bearing modification or delete flow process.
Above-mentioned steps 21 and 22 is that HSS initiates the insertion flow process of subscription data to the network equipment, after step 21 and 22, subscription data in MME or SGSN there occurs change, the most default QoS there occurs change, then after the insertion flow process of subscription data, MME or SGSN initiates the amendment of carrying the most immediately or deletes flow process, but first whether detection user has signaling to be connected with oneself, then does different disposal:
If UE with MME or SGSN has signaling to be connected, MME or SGSN initiates the amendment of carrying or deletes flow process；
If not having signaling to be connected between UE with MME or SGSN, MME or SGSN does not initiate the amendment of carrying or deletes flow process.Until UE oneself initiates se ce request procedure, or when network side receives downlink data or signaling and triggers UE generation se ce request procedure, MME or SGSN detects that UE has been in connection status, initiates the amendment of carrying the most again or deletes flow process.
This embodiment can also be applied to the scene under ISR mechanism, and HSS is after MME and/or SGSN initiates the insertion flow process of subscription data, MME and SGSN both sides can be respectively according to above-mentioned mechanism individual processing.
The processing method to carrying of the present embodiment, at HSS after mobile management device initiates the insertion flow process of subscription data, if the subscription data in MME or SGSN changes, then after the insertion flow process of subscription data, MME or SGSN initiates the amendment of carrying the most immediately or deletes flow process, and it is intended to when detecting that user has signaling to be connected with oneself, initiate the amendment of carrying again or delete flow process, therefore MME or SGSN will not carry out single paging to realize bearing modification, thus saves the available resources on MME or SGSN.
At saving signaling (ISR, IdleStateSignalingReduction) under mechanism, subscriber equipment (UE, UserEquipment) need to be registered to MME and SGSN respectively, after the HSS of double registrations initiates the insertion flow process of subscription data to MME and SGSN simultaneously, according to current mechanism, MME and SGSN can initiate the amendment of context respectively or delete flow process.Same user on S-GW is carried, if MME and SGSN initiates amendment or the removal request of this carrying simultaneously to S-GW, the solicited message that S-GW can arrive after discarding, if and user is just under the access way that later solicited message is corresponding, bearing modification or deletion flow process that the solicited message then arrived first causes will perform in opposite side access network, even if the bearing modification that this solicited message arrived first causes or deletion flow process can be successful, if perform this bearing modification or delete flow process based on subscription data be not inconsistent with this side (access way that later solicited message is corresponding) subscription data, after then, MME or SGSN of this side also may proceed to initiate the modification process of carrying, thus waste signaling number.And utilize the processing method to carrying of the embodiment of the present invention, then can avoid the waste to signaling number.Below for this example.

204.SGSN updates the subscription data preserved, and replys to HSS and inserts subscription data confirmation message；
205.MME judges that UE is the most movable under the management of MME；
After 206.MME determines that UE activity is under the management of MME, initiate bearing modification or delete flow process.
207.SGSN judges that UE is the most movable under the management of MME；
After 208.SGSN determines that UE activity is under the management of MME, initiate bearing modification or delete flow process.
In above-mentioned steps 205 and step 207, MME or SGSN can judge that UE is the most movable under the management of oneself by the following method:
MME or SGSN judge UE whether with oneself have signaling to connect, have a detailed description before concrete determination methods.If it is determined that user has signaling to be connected with oneself, may determine that UE is under the management of oneself；If it is determined that user does not has signaling to be connected with oneself, then calling user, detect whether to cause user to trigger service request, if be detected that user triggers service request, then may determine that UE is under the management of oneself, without detecting that user triggers service request, then may determine that UE is not under the management of oneself.
When side MME or SGSN relevant to UE determines that UE is under the management of oneself, notify that opposite side SGSN or MME relevant to UE stops UE being carried out paging by sending stopping paging (StopPaging) message or other new message.
It should be noted that above-mentioned steps 201,202 and step 203, carry out side by side between 204, the most temporal sequencing.Same step 205,206 and step 207, carry out side by side between 208, the most temporal sequencing.
Above-mentioned steps 201 and 202, step 203 and 204 are that HSS initiates the insertion flow process of subscription data to the network equipment.
After step 201 and 202, subscription data in MME there occurs change, the most default QoS there occurs change, then after the insertion flow process of subscription data, MME initiates the amendment of carrying the most immediately or deletes flow process, but first determines the existence of UE, and when specifically can be connected with the signaling set up between UE by detection or be connected without signaling, calling user causes UE to trigger service request, determine that UE, whether under the management of MME, then does different disposal according to the result determined:
If UE is under the management of MME, MME initiates the amendment of carrying or deletes flow process；
If UE is not under the management of MME, MME does not initiate the amendment of carrying or deletes flow process.
Equally, after step 203 and 204, subscription data in SGSN there occurs change, the most default QoS there occurs change, then, after the insertion flow process of subscription data, SGSN initiates the amendment of carrying the most immediately or deletes flow process, but first determine the existence of UE, when specifically can is connected with the signaling set up between UE by detection or be connected without signaling, calling user causes UE to trigger to service and ask, and determines that UE, whether under the management of SGSN, then does different disposal according to the result determined:
If UE is under the management of SGSN, SGSN initiates the amendment of carrying or deletes flow process；
If UE is not under the management of SGSN, SGSN does not initiate the amendment of carrying or deletes flow process.
