Description
Technical field
The present invention relates to communication technical field, be meant the successional method and apparatus of a kind of maintenance urgency traffic especially.
Background technology
In the existing protocol system, defined packet data network (PDN) the connection deactivation process that Mobility Management Entity (MME) is initiated.For example forbid inserting some APN (APN) or MME resource shortage if home subscribed services device (HSS) changes a certain user terminal of indication (UE), MME will initiate PDN and remove connection procedure.
Fig. 1 removes connection procedure for the PDN that MME initiates.Referring to shown in Figure 1, the PDN that MME initiates goes the concrete steps of connection procedure as follows:
When step 101:MME decision discharges the PDN connection, carry out PDN and go to connect trigger process.
Step 102:MME sends deleting bearing request (Delete Bearer Request) message and gives service (Serving) gateway (GW), grouping system (EPS) carrying of the evolution that connects with a certain PDN of request Serving GW deexcitation.In this message, also carry all carryings that an indication requires this PDN of deletion to connect.
Step 103:Serving GW sends Delete Bearer Request message to PDN GW.
After step 104:PDN GW receives Delete Bearer Request message, return deleting bearing response (Delete Bearer Response) message to Serving GW.
Step 105:PDN GW carries out IP-CAN connection termination (sessionTermination) process that PCRF initiates.
Step 106:Serving GW returns Delete Bearer Response message to MME.
After step 107:MME receives Delete Bearer Response message, send load bearing deactivation message, require eNodeB to delete all carryings of this PDN join dependency to eNodeB.
Step 108:eNodeB sends RRC reprovision (RRC Connection Reconfiguration) message to UE, requires UE to discharge all relevant radio bearers.
After step 109:UE receives RRC Connection Reconfiguration message, discharge all carryings of this PDN join dependency and return RRC reprovision affirmation (RRC ConnectionReconfiguration Complete) message to eNodeB.
After step 110:eNodeB receives RRC Connection Reconfiguration Complete, return deexcitation carrying response (Deactivate Bearer Response) message to MME.
Step 111: if subscription data indication user allows to carry out the handoff procedure that non-3GPP inserts, and in the non-3GPP system, there is not the PDN of same APN to connect, after ME receives DeactivateBearer Response message, send notice request (Notify Request) message to HSS, and the PDN GW address information of notifying HSS to delete this APN.
After the step 112:HSS deletion PDN GW address information, return push-notification-answer (NotifyResponse) message to MME.
When overload took place eNodeB, eNodeB can transship to the MME indication, and the carrying that requires MME to discharge some UE connects.When if UE requires all carryings of a certain UE of deletion, MME receives the UE context dispose procedure that can initiate the S1 interface behind the request back, discharge UE the S1 interface with eat dishes without rice or wine all be connected.
When overload took place Serving GW, Serving GW also can indicate overload to MME, and required MME to discharge the carrying connection of some UE, and this moment, all carrying connections of UE also can be released.
When the CAMEL-Subscription-Information of a UE among the HSS changes, when the CAMEL-Subscription-Information that sends this user terminal to MME is recalled indication, MME receives when the CAMEL-Subscription-Information of this user terminal is recalled, and initiate the attachment removal process of this UE, and all carrying connections of this UE this moment all will be by deexcitation.Do not belong to signing service because urgency traffic connects, only relevant with this locality configuration, it is irrational therefore ending urgency traffic this moment.
If the normal attach of UE has initiated the urgency traffic connection behind network, after urgency traffic is activated, stipulate in the existing protocol, if this moment, the eNB of this UE service transshipped, or overload notification MME when taking place in Serving GW, or the indication of the CAMEL-Subscription-Information among the HSS " CAMEL-Subscription-Information is recalled ", when requiring MME with the UE attachment removal etc. under the scene, MME can connect all carryings of UE according to prior protocols and discharges, and this moment, all business of UE will be ended, certainly, the urgency traffic that also can discharge UE this moment connects, therefore, in the prior art under some scene, can't guarantee the continuity of user's urgency traffic connection, not satisfy user's urgent need.
