Abstract

This paper discloses a mobility management method and device, the method includes: after the UE in the inactive state or the light-connected state satisfies the conditions for changing the cell and determines the target base station for the changing cell, determining the changing cell of the user equipment UE performing the handover of the UE according to the determined cell-changing mode; the UE's cell-changing mode includes at least one of the following: keeping the user plane link of the UE at the source base station; transferring the user plane link of the UE to the target base station. The present application implements mobility management between LTE and 5G New RAT in an inactive state or a light connected state.

Description

technical field

[0001] The present invention relates to the field of communications, in particular to a mobility management method and device. Background technique

[0002] In the long term evolution (Long Term Evaluation, LTE) standard and 5G new radio access network (Radio Access Network, RAN) standard currently discussed by the 3rd Generation Partnership Project (3GPP, the 3rd Generation Partnership Project), LTE is introduced respectively. In the light connected state, the inactive state is introduced in the 5G new RAT. These two states are similar in nature. For LTE RAN and 5G RAN, both the light connected state and the inactive state belong to Radio Resource Control (RRC). , Radio Resource Control) is a sub-state of the connected state. If the terminal is in the light connected state or inactive state, its RRC connection with the RAN is still maintained, and the signaling bearer and data bearer are still maintained, but the difference from the RRC connected state is: t...
