Method and apparatus for status transition

摘要

A method and apparatus for status transition are provided in the disclosure, which enable a wireless side network element to judge that a service request message is a paging response message after receiving the service request message, transmit an initial user equipment message to a mobility management entity, and indicate that the service request message is valid in the initial user equipment message. The method and apparatus of the disclosure solve the problem that the mobility management entity is unable to make a correct judgment and corresponding logical processing, and improve processing efficiency of the mobile communication system effectively.

1. A method for status transition, applied to a local IP access connection process of a wireless side network element or a H(e)NB gateway in packet switch (PS) domain, comprising:
sending a paging message to a terminal when downlink data of the local IP connection reaches the wireless side network element/local gateway; sending a service request message to a mobility management entity after receiving the service request message from the terminal as a paging response, and indicating that the service request message is valid in initial user equipment (UE) message; wherein the method for indicating that the service request message is valid comprises: modifying service type information element (IE) to indicate “data” or “signaling” which is taken as reason code in the service request message, wherein the reason code represents UE has pending user data or signaling to be sent, or carrying reason code in an initial user equipment message, wherein the reason code represents that the service request message is a response message of paging performed by the wireless side network element; the paging response message is a response to the paging of the wireless side network element or the H(e)NB gateway.
