Abstract
A core network node for mobility management includes a means for transmitting information related to expected mobility of user equipment, UE, to an access network node.
Claims10
A mobility management method executed by an Access and Mobility Management Function (AMF) node, the mobility management method comprising:
- retrieving an expected User Equipment (UE) behavior parameter from a data management node;
- and
- sending, to a radio access network (RAN), a message for N2 connection between the AMF node and the RAN based on the expected UE behavior parameter, wherein the message comprises assistance information for controlling radio resource control (RRC) Inactive state transitions in the RAN,
- wherein the assistance information comprises expected UE moving trajectory information indicating the UE's expected movement and UE mobility information indicating whether the UE is stationary or mobile.

A mobility management method executed by a radio access node (RAN), the mobility management method comprising:
- receiving, from an Access and Mobility Management Function (AMF) node that retrieves an expected User Equipment (UE) behavior parameter from a data management node, a message for N2 connection between the AMF node and the RAN based on the expected UE behavior parameter, wherein the message comprises assistance information for controlling radio resource control (RRC) Inactive state transitions in the RAN, and wherein the assistance information comprises expected UE moving trajectory information indicating the UE's expected movement and UE mobility information indicating whether the UE is stationary or mobile.
An Access and Mobility Management Function (AMF) node, comprising:
- a memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- retrieve an expected User Equipment (UE) behavior parameter from a data management node, and
- send, to a radio access network (RAN), a message for N2 connection between the AMF node and the RAN based on the expected UE behavior parameter, wherein the message comprises assistance information for controlling radio resource control (RRC) Inactive state transitions in the RAN, and wherein the assistance information comprises expected UE moving trajectory information indicating the UE's expected movement and UE mobility information indicating whether the UE is stationary or mobile.
