Abstract
This application provides a method and an apparatus for selecting a session management network element. The mobility management network element may obtain the information about the one or more first session management network elements, and support to select a session management network element in a home routed mode or an enhanced topology mode.
Claims20
A method for selecting a session management network element, comprising:
- receiving, by a service communication proxy network element, a first message from a mobility management network element;
- obtaining, by the service communication proxy network element, first parameter information based on the first message, wherein the first parameter information comprises user equipment UE location information and a data network name DNN;
- determining, by the service communication proxy network element, whether there is a session management network element that satisfies the first parameter information;
- and
- when there is no session management network element that satisfies the first parameter information, sending, by the service communication proxy network element, a reject message to the mobility management network element, wherein the reject message is used to indicate that there is no session management network element that satisfies the first parameter information.
2 more elements
An apparatus for selecting a session management network element, comprising:
- a transceiver module, configured to receive a first message from a mobility management network element;
- and
- a processing module, configured to obtain first parameter information based on the first message, wherein the first parameter information comprises user equipment UE location information and a data network name DNN;
- and determine whether there is a session management network element that satisfies the first parameter information, wherein when there is no session management network element that satisfies the first parameter information, the processing module is further configured to invoke the transceiver module to send a reject message to the mobility management network element, wherein the reject message is used to indicate that there is no session management network element that satisfies the first parameter information.
