US 2014/0153474 A1 · METHOD, BASE STATION AND SYSTEM FOR RESELECTION OR HANDOVER TO BROADCAST MULTICAST CELL

Abstract

The present invention discloses a method and system for reselecting or handing over to a broadcast multicast cell. The method includes the following steps: broadcasting, by an MBMS cell, a service area identity list of a service area to which the MBMS cell belongs; determining, by a UE, whether the service area identity list includes a service area identity corresponding to a service; if the service area identity list includes service area identity corresponding to the service, setting, by the UE, a cell reselection priority of a frequency of an MBMS cell to the highest. According to the present invention, a UE can identify whether a cell capable of providing services that the UE is receiving or is interested in around the UE, so that the cell can learn which neighboring cells are MBMS cells and what services are being broadcast in MBMS cells if such MBMS cells are available.

Dependent claims

A method for setting a frequency priority, comprising:

receiving, by a user equipment (UE), a service area identity list of a service area of a multimedia broadcast multicast service (MBMS) cell broadcast by a base station to which the MBMS cell belongs;
determining, by the UE, whether the service area identity list comprises a service area identity corresponding to an MBMS service that the UE is receiving or is interested in;
and
if the service area identity list comprises the service area identity corresponding to the MBMS service that the UE is receiving or is interested in, setting, by the UE, a cell reselection priority of a frequency of the MBMS cell to the highest.

1 more element

A user equipment (UE), comprising:

a receiver, configured to receive a service area identity list of a service area of a multimedia broadcast multicast service (MBMS) cell broadcast by a base station to which the MBMS cell belongs;
a processor, configured to determine whether the service area identity list comprises a service area identity of an MBMS service that the UE is receiving or is interested in;
and if the service area identity list comprises a service area identity corresponding to the MBMS service that the UE is receiving or is interested in, to set a cell reselection priority of a frequency of the MBMS cell to the highest.

A base station, comprising:

a transmitter and a memory;
wherein the transmitter is configured to broadcast a service area identity list of a service area of a multimedia broadcast multicast service (MBMS) cell of the base station, wherein the service area identity list is used for a UE to set a cell reselection priority of a frequency of the MBMS cell to the highest, when the UE determines that the service area identity list comprises a service area identity corresponding to an MBMS service that the UE is receiving or is interested in after the UE receives the service area identity.
