Below in conjunction with the accompanying drawing in the application, carry out clear, complete description to the technical scheme in the application, obviously, described embodiment is a part of embodiment of the application, instead of whole embodiments.Based on the embodiment in the application, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the application's protection.Wherein, for convenience of description and understand, in the examples below, take network equipment as MME(MobilityManagementEntity, mobile management entity) be described for example.But should be realized that, in the technical scheme that the embodiment of the present invention provides, network equipment is not limited to MME, also can be other with MME, there is the network equipment of similar or identical function.
Embodiment one
As shown in Figure 1, be the schematic flow sheet of a kind of PDN connection establishment method that the embodiment of the present invention provides, can comprise the following steps:
Step 101, MME receive the PDN connection request that UE sends, and obtain the precedence information that APN, PDNtype of carrying in this PDN connection request and institute asks the PDN connection of foundation.
Concrete, when MME receives the PDN connection request that UE sends, MME can obtain the precedence information that APN, PDNtype of carrying in this PDN connection request and institute asks the PDN connection of foundation.Wherein, carry in this PDN connection request ask the PDN set up to connect precedence information can for the precedence information in the device attribute (Deviceproperties) of carrying in this PDN connection request.
Step 102, MME judge that whether APN and PDNtype carried in this PDN connection request be identical with APN and PDNtype that the PDN that this UE has set up connects; If be judged as YES, then go to step 103; Otherwise, go to step 104.
Concrete, when MME get APN, PDNtype of carrying in the PDN connection request received and ask the PDN set up to connect precedence information after, MME can judge that whether APN and PDNtype carried in this PDN connection establishment request be identical with APN and PDNtype that the PDN that this UE has set up connects, if identical, then further according to ask set up PDN connect precedence information determine accept this PDN connection request or refuse this PDN connection request; If different, then accept this PDN connection request.
Wherein, MME can determine by the bearer context information (BearerContext) of the UE of self storage APN and PDNtype that the PDN that UE has set up connects.
Step 103, MME according to carry in this PDN connection request ask set up PDN connect precedence information determine accept this PDN connection request or refuse this PDN connection request.
Concrete, when MME determines that APN and PDNtype that carry in this PDN connection request is identical with APN and PDNtype that the PDN that this UE has set up connects, MME can judge further ask the PDN set up to connect the priority that is connected with the PDN that this UE has set up of priority, and determine to accept this PDN connection or refuse this PDN to connect according to comparative result.Wherein, MME can determine according to the low priority instruction in the bearer context information of the UE of self storage the priority that the PDN that UE has set up connects.
Wherein, when MME determine ask set up PDN connect priority identical with the priority that the PDN that this UE has set up connects time, MME can refuse this PDN connection request, sends the PDN carrying corresponding cause value connect refusal (PDNconnectivityreject) message to UE.In this case, this cause value can be " #55 ", namely " multiplePDNconnectionsforagivenAPNnotallowed(does not allow for same APN and sets up many PDN connections) ", its concrete meaning see existing protocol relevant regulations, can not repeat them here.
When MME determine ask set up PDN connect priority different from the priority that the PDN that this UE has set up connects time, MME can judge whether to allow for this UE and set up the PDN connection that institute ask foundation, if be judged as YES, then accept this PDN connection request, initiate default EPS (EvolvedPacketSystem, evolved packet system) bearer context activation; If be judged as NO, then refuse this PDN connection request, send the PDN connection refused message of corresponding cause value to UE.
Wherein, MME can judge whether to allow for this UE and sets up institute and ask the PDN of foundation connection at least can comprise following two kinds of situations:
Situation one, set up be correlated with from same APN, PDNtype is identical, PDN that priority is different connects is a kind of subscription data.
In this case, first MME needs the CAMEL-Subscription-Information searching UE, and judge whether it contracts " set up be correlated with from same APN, PDNtype is identical, PDN that priority is different connects ".
This attribute if UE has contracted, then MME can according to the congestion condition of current network and ask the PDN set up to connect priority judge whether to allow for this UE and set up the PDN connection that institute ask foundation, if the determination result is YES, then accept this PDN connection request, send " ActivatedefaultEPSbearercontextrequest(default EPS bearing Context activation request) message " to UE, initiate default EPS bearing context activation Procedure; If judged result is no, then refuse this PDN connection request, send the PDN connection refused message of carrying corresponding cause value to UE.In this case, this cause value can be " #26 ", and namely " insufficientresources(inadequate resource) ", its concrete meaning see the regulation in relevant existing protocol, can not repeat them here.
Wherein, MME according to the congestion condition of current network and ask the PDN set up to connect priority judge whether to allow for this UE and set up institute and ask the realization of the PDN of foundation connection identical with relevant treatment in prior art, do not repeat them here.
If UE this attribute not signing, then refuse this PDN connection request, send the PDN connection refused message of carrying corresponding cause value to UE.In this case, this cause value can be " not signing multipriority PDN connection attribute ".
Situation two, set up be correlated with from same APN, PDNtype is identical, PDN that priority is different connects is not a kind of subscription data.
In this case, MME can according to the congestion condition of current network and ask the PDN set up to connect priority judge whether to allow for this UE and set up the PDN connection that institute ask foundation, if the determination result is YES, then accept this PDN connection request, send " ActivatedefaultEPSbearercontextrequest(default EPS bearing Context activation request) message " to UE, initiate default EPS bearing context activation Procedure; If judged result is no, then refuse this PDN connection request, send the PDN connection refused message of carrying corresponding cause value to UE.
Step 104, MME accept this PDN connection request.
Concrete, when ask set up PDN connect APN and PDNtype and UE set up PDN connection APN and PDNtype different time, MME think can for this UE set up its ask set up PDN connect, default EPS bearing Context activation request message is sent to UE, initiate default EPS bearing context activation Procedure, its specific implementation flow process is identical with related procedure of the prior art, does not repeat them here.
Should be realized that; in embodiments of the present invention; the cause value carried in PDN connection refused message is not limited to the cause value described in above-described embodiment; on the basis of the technical scheme provided in the embodiment of the present invention, those skilled in the art all should belong to scope not paying the other reasons value expected under creative work prerequisite.In addition, in embodiments of the present invention, UE ask set up PDN connect priority the precedence information in the device attribute by carrying in PDN connection request might not be needed to determine, also can by the mode of new field, carry in PDN connection request ask the PDN set up to connect priority; Correspondingly, the priority that the PDN that UE has set up connects also is not limited to judge according to the low priority instruction in the bearer context information of this UE stored in MME, can be determined by other new fields or mark, its specific implementation flow process does not repeat them here yet.
Below in conjunction with embody rule scene, the technical scheme that the embodiment of the present invention provides is further described in more detail.

Step 203, MME judge whether UE has contracted " setting up that be correlated with from same APN, that PDNtype is identical, priority is different PDN to connect ".If be judged as YES, then go to step 204; Otherwise, go to step 206.
Step 204, MME according to the congestion condition of current network and ask the PDN connection priority set up to judge whether to allow for this UE to set up the PDN connection that its institute asks to set up.If be judged as YES, then go to step 205; Otherwise, go to step 206.
Step 205, MME send default EPS bearing Context activation request (ActivatedefaultEPSbearercontextrequest) to UE, initiate default EPS bearing context activation Procedure.
Step 206, MME send to UE the PDN carrying corresponding cause value and connect refusal (PDNconnectivityreject) message.
Wherein, when MME determines UE not signing " setting up that be correlated with from same APN, that PDNtype is identical, priority is different PDN to connect ", then this cause value can be " not signing multipriority PDN connection attribute "; When MME according to the congestion condition of current network and ask the PDN connection priority set up determine not allow for this UE set up the PDN connection that its institute asks to set up time, this cause value can be " inadequate resource (insufficientresources) ".

Step 301, UE send PDN connection request (PDNconnectivityrequest) to MME.Wherein, the APN carried in this PDN connection request is APN1, PDNtype is IPv6, and priority is the priority of application program.
Step 302, MME receive the PDN connection request that UE sends, determine ask the PDN set up to connect APN and APN and PDNtype that connect of the PDN that set up of PDNtype and UE identical, but institute asks the priority of the PDN of foundation connection different from the priority that the PDN that this has been set up connects.
Step 303, MME according to the congestion condition of current network and ask the PDN connection priority set up to judge whether to allow for this UE to set up the PDN connection that its institute asks to set up.If be judged as YES, then go to step 304; Otherwise, go to step 305.
Step 304, MME send default EPS bearing Context activation request (ActivatedefaultEPSbearercontextrequest) to UE, initiate default EPS bearing context activation Procedure.
Step 305, MME send to UE the PDN carrying corresponding cause value and connect refusal (PDNconnectivityreject) message.
By describing above and can finding out, in embodiments of the present invention, when MME receives the PDN connection request of UE transmission, and when determining that APN and PDNtype that the PDN that the APN that carries in this PDN connection request and PDNtype and UE has set up connects is identical, MME according to carry in described PDN connection request ask set up PDN connect precedence information determine accept this PDN connection request or refuse this PDN connection request, achieve as UE sets up relevant to same APN, PDNtype is identical, the PDN that priority is different connects, reduce the time delay of PDN connection establishment, and the current business data flow using the PDN set up to connect transmission data can not be interrupted.
