Abstract

The present disclosure provides an inter-radio access network mobility management method, a core network device, and a base station. When an inter-system movement occurs on a terminal in an inactive state, user context information of the terminal in the inactive state in NR system is still retained; and the user context information is deleted until certain conditions are satisfied. The disclosure achieves inter-RAY mobility management of a terminal in an inactive state and solves an inter-system mobility problem, so that the terminal can operate normally.

Description

Technical field

[0001] The present invention relates to the field of mobile communication technology, in particular to a mobility management method between wireless access networks, core network equipment and base stations. Background technique

[0002] With the development of wireless communication systems, terminal types and service types are diversified, and the terminals save power, save network resources and meet the needs of various service types. In order to ensure both terminal power saving and fast data transmission, a new mobility state is introduced in the New Radio Access Technology (New RAT) of the 5G New Air Interface (NR) system: RRC_INACTIVE (also called inactive state in this article) Or inactive state).

[0003] In the inactive state, the terminal maintains the core network connection, but does not perform normal operations in the air interface connection state (such as handover, uplink timing update, radio link monitoring, etc.), and does not allocate terminal i...
