Method and apparatus for handling connections
The embodiments of the present disclosure provide a method and an apparatus for connection handling. The method includes: receiving a connection request that requests for establishing or resuming a connection with a base station; and instructing a Non-Access Stratum (NAS) of a terminal to perform a predetermined operation based on an obtained first connection result corresponding to the connection request. In this way, the problems associated with inconsistent operations in the user plane optimization in the related art can be solved and the consistency in operations between the Access Stratum (AS) and NAS of the terminal can be achieved.
1. A method for connection handling, comprising:
receiving, by a first network element, a first message carrying a first resume identity from a terminal;
determining, by the first network element, a second resume identity based on the first resume identity; and
transmitting, by the first network element, a second message carrying the second resume identity to one or more second network elements to request the one or more second network elements to transfer context information of the terminal to the first network element based on the second resume identity, wherein the second message carries information indicating a format of the second resume identity.
2. The method of claim 1 , wherein the information indicating the format of the second resume identity comprises:
information indicating a length of second resume identity.
3. The method of any of claim 1 , wherein
the first message comprises a connection resumption request message over an air interface, and
the second message comprises one of: a terminal context retrieval request message over an X2 interface.
4. The method of claim 1 , wherein the information indicating the format of the second resume identity comprises:
an indicator indicating whether the second resume identity has a truncated format.
5. An apparatus for connection handling, comprising:
a receiver configured to receive a first message carrying a first resume identity from a terminal;
a processor configured to determine a second resume identity based on the first resume identity; and
a transmitter configured to transmit a second message carrying the second resume identity to one or more second network elements to request the one or more second network elements to transfer context information of the terminal to the first network element based on the second resume identity, wherein the second message carries information indicating a format of the second resume identity.
6. The apparatus of claim 5 , wherein the information indicating the format of the second resume identity comprises information indicating a length of the second resume identity.
7. The apparatus of claim 5 , wherein the first message comprises a connection resumption request message over an air interface, and the second message comprises a terminal context retrieval request message over an X2 interface.
8. The apparatus of claim 5 , wherein the information indicating the format of the second resume identity comprises an indicator indicating whether the second resume identity has a truncated format.
9. A non-transitory computer storage medium having code stored thereon, the code when executed by a processor, causing the processor to implement a method that comprises
receiving, by a first network element, a first message carrying a first resume identity from a terminal;
determining, by the first network element, a second resume identity based on the first resume identity; and
transmitting, by the first network element, a second message carrying the second resume identity to one or more second network elements to request the one or more second network elements to transfer context information of the terminal to the first network element based on the second resume identity, wherein the second message carries information indicating a format of the second resume identity.
10. The non-transitory computer storage medium of claim 9 wherein the information indicating the format of the second resume identity comprises information indicating a length of the second resume identity.
11. The non-transitory computer storage medium of claim 9 , wherein the first message comprises a connection resumption request message over an air interface, and the second message comprises a terminal context retrieval request message over an X2 interface.
12. The non-transitory computer storage medium of claim 9 , wherein the information indicating the format of the second resume identity comprises an indicator indicating whether the second resume identity has a truncated format.
