Session management method and device in N2 interface switching scene

Abstract

The embodiment of the invention provides a session management method and device in an N2 interface switching scene, and the method comprises the steps: obtaining a session endpoint identification andan IP address of a receiving end of a target NGAP message carried by the target NGAP message, judging whether an NGAP session of which the session endpoint identifier and the IP address in the contextare the same as the session endpoint identifier and the IP address of the receiving end exists in the established NGAP session; and if the target NGAP message exists, updating the value of the targetcell in the NGAP session of which the session endpoint identifier and the IP address in the context are the same as the session endpoint identifier and the IP address of the receiving end according to the message type of the target NGAP message. According to the session management method and device in the N2 interface switching scene provided by the embodiment of the invention, the messages of the signaling process of the N2 interface can be associated under the messages belonging to the same user, and the session management of the NGAP protocol in the N2 interface switching scene can be realized more conveniently.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a session management method and device in an N2 interface switching scenario. Background technique [0002] In the 5G system, the N2 interface is the interface between NG-RAN and AMF. NG-RAN (NG Wireless Access Network, also known as RAN) is a wireless access network. AMF (Access and Mobility Management) is an access and mobility management network element, which is used to terminate the N2 interface of the RAN control plane and terminate N1 (NAS, Non-Access-Stratum, non-access stratum, signaling messages between UE and AMF ) interface to implement NAS encryption and integrity protection, as well as UE (User Equipment, User Equipment) registration, connection, reachability and mobility management functions. [0003] The NGAP (NG Application Protocol, NG Application Protocol, application layer protocol of the N2 interface) message in the signaling process of the N...
