Abstract
The present invention provides a method for RN switching and location updating, a method for updating location of UE and a method for paging UE. Application of the methods of the present invention, can present each UE under the relay from initiating a tracking area update process, reduce network congestion, and save system sources.
Claims10
A method of a user equipment (UE) in a mobile communication system, the method comprising:
- receiving, from a mobile relay node (RN), a message including a tracking area identifier (TAI) list determined based on a predetermined movement route of the UE;
- receiving a TAI from the mobile RN;
- determining whether the received TAI is included in the TAI list;
- and
- if the received TAI is included in the TAI list, omitting a tracking area update (TAU) process,
- wherein the TAI list is assigned by a mobile management entity (MME) based on at least one of an indication indicating that the UE is located in a first cell of the mobile RN or an identifier of the first cell in which the UE is located,
- wherein the TAI list is updated based on a location of the UE changed from the first cell to a second cell of the mobile RN and the updated TAI list is transmitted to the UE, and
- wherein the updated TAI list includes at least one TAI to be broadcast by the mobile RN in the second cell, and the at least one TAI is transmitted from the MME to the mobile RN in a location update process of the mobile RN related to the changed location of the UE.

A user equipment (UE) in a mobile communication system, the UE comprising:
- a transceiver configured to:
- receive, from a mobile relay node (RN), a message including a tracking area identifier (TAI) list determined based on a predetermined movement route of the UE;
- and
- receive a TAI from the mobile RN;
- and
- a processor configured to:
- determine whether the received TAI is included in the TAI list;
- and
- if the received TAI is included in the TAI list, omit a tracking area update (TAU) process,
- wherein the TAI list is assigned by a mobile management entity (MME) based on at least one of an indication indicating that the UE is located in a first cell of the mobile RN or an identifier of the first cell in which the UE is located,
- wherein the TAI list is updated based on a location of the UE changed from the first cell to a second cell of the mobile RN, and the updated TAI list is transmitted to the UE, and
- wherein the updated TAI list includes at least one TAI to be broadcast by the mobile RN in the second cell, and the at least one TAI is transmitted from the MME to the mobile RN in a location update process of the mobile RN related to the changed location of the UE.
