Embodiment one
As shown in Figure 1, a kind of PDN that provides for the embodiment of the invention connects the schematic flow sheet of method for building up, can may further comprise the steps:
Concrete, when MME received the PDN connection request of UE transmission, MME can obtain the precedence information of the PDN connection of APN, the PDN type that carries in this PDN connection request and the foundation of asking.The precedence information that the PDN of the foundation of asking of wherein, carrying in this PDN connection request connects can be the precedence information in the device attribute (Device properties) of carrying in this PDN connection request.
Concrete, after MME gets access to the precedence information that the APN, the PDN type that carry in the PDN connection request that receives and the PDN that asks to set up connect, MME can judge whether this PDN connects APN and the PDN type of the PDN connection that the APN that carries in the request of foundation and PDN type and this UE set up identical, if identical, the precedence information that then further connects according to the PDN that asks to set up is determined to accept this PDN connection request or is refused this PDN connection request; If different, then accept this PDN connection request.
Wherein, MME can determine APN and the PDN type that PDN that UE has set up connects by the bearer context information (Bearer Context) of UE of self storage.
Concrete, when MME determines that APN that the APN that carries in this PDN connection request and PDN type and the PDN that this UE has set up connect and PDN type are identical, MME can further judge the priority that the priority that the PDN that asks to set up connects has been connected with the PDN that this UE has set up, and determines to accept this PDN connection or refuse this PDN connection according to comparative result.Wherein, the priority of the MME PDN connection that can indicate to determine that UE has set up according to the low priority in the bearer context information of UE of self storage.
Wherein, when MME determines that the priority of the PDN connection that priority that institute ask the PDN connection of setting up and this UE have set up is identical, MME can refuse this PDN connection request, sends the PDN that carries corresponding cause value to UE and connects refusal (PDN connectivity reject) message.In this case, this cause value can be " #55 ", namely " multiple PDN connections for a given APN not allowed(does not allow for same APN and sets up many PDN connections) ", its concrete meaning can referring to the existing protocol relevant regulations, not repeat them here.
When determining institute, MME ask priority that the priority of the PDN connection of foundation is connected with PDN that this UE has set up not simultaneously, MME can judge whether to allow for the PDN connection that this UE sets up the foundation of asking, if be judged as be, then accept this PDN connection request, initiate default EPS (Evolved Packet System, evolved packet system) bearer context activation; If be judged as noly, 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 connection of foundation can comprise at least following two kinds of situations:
PDN connections that situation one, foundation are correlated with from same APN, that PDN type is identical, that priority is different are a kind of subscription data.

This attribute if UE has contracted, then MME can judge whether to allow for this UE according to the priority that the congestion condition of current network and the PDN that asks to set up connect and set up the PDN connection that institute ask foundation, if judged result is yes, then accept this PDN connection request, send " request of Activate default EPS bearer context request(default EPS bearing context activation) message " to UE, initiate default EPS bearing context activation process; If the determination 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 " insufficient resources(inadequate resource) ", its concrete meaning can referring to the regulation in the relevant existing protocol, not repeat them here.
Wherein, the priority that MME connects according to the congestion condition of current network and the PDN that asks to set up judges whether to allow for this UE and sets up institute and ask the realization of PDN connection of foundation identical with relevant treatment in the prior art, does not repeat them here.
If not signatory this attribute of UE is then refused 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 signatory multipriority PDN connection attribute ".
PDN connections that situation two, foundation are correlated with from same APN, that PDN type is identical, that priority is different are not a kind of subscription data.
In this case, the priority that MME can connect according to the PDN of the congestion condition of current network and the foundation of asking judges whether to allow for the PDN connection that this UE sets up the foundation of asking, if judged result is yes, then accept this PDN connection request, send " request of Activate default EPS bearer context request(default EPS bearing context activation) message " to UE, initiate default EPS bearing context activation process; If the determination result is NO, then refuse this PDN connection request, send the PDN connection refused message of carrying corresponding cause value to UE.
Concrete, the APN that the APN that connects as the PDN that asks to set up and PDN type are connected with the PDN that UE has set up and PDN type are not simultaneously, MME thinks and can ask the PDN that sets up to connect for this UE sets up it, send default EPS bearing context activation request message to UE, initiate default EPS bearing context activation process, 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 that carries in the PDN connection refused message is not limited to the cause value described in above-described embodiment; on the basis of the technical scheme that the embodiment of the invention provides, those skilled in the art all should belong to protection range of the present invention not paying the other reasons value of expecting under the creative work prerequisite.In addition, in embodiments of the present invention, the priority that UE asks the PDN that sets up to connect might not need to determine by the precedence information in the device attribute of carrying in the PDN connection request, also can by the mode of new field, in the PDN connection request, carry the priority of the PDN connection of the foundation of asking; Correspondingly, the priority that the PDN that UE has set up connects also is not limited to indicate to judge according to the low priority in the bearer context information of this UE that stores among the MME, can determine by other new fields or sign, its specific implementation flow process does not repeat them here yet.
