Embodiment Construction

[0055] Several preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, detailed descriptions of known functions and configurations incorporated herein have been omitted for conciseness.

[0056] The present invention proposes a method for providing MBMS service to multiple UEs located in different FAs covering the same geographical area. In addition, the present invention proposes a method for allowing a UE located in an FA where the MBMS service is not available to receive the MBMS service.

[0057] refer to Figure 5 , a method of allowing a UE located in an FA where the MBMS service is not available to receive the MBMS service when there is one FA where the MBMS service is available among a plurality of FAs overlapping each other in the same area will now be described.

[0058] Figure 5 is a message flow diagram illustrating a procedure for providing information on FAs avai...

Abstract

A method for selecting a cell by a user equipment (UE) to receive a Multimedia Broadcast / Multicast Service (MBMS) service in a mobile communication system which supports the MBMS service with different frequency allocations (FAs) in the same area. In the method, a radio network controller (RNC) transmits information on an MBMS cell to the UE, and the MBMS cell information includes an MBMS offset for guaranteeing priority for cell reselection to the MBMS cell. The UE performs cell reselection using the MBMS cell information and receives the MBMS service from the reselected cell.

Description

technical field [0001] The present invention relates generally to packet data services, and more particularly to a method for sending information about cells available for a particular packet data service when cells available for packet data services overlap with cells not available for packet data services to the user equipment (UE), thereby providing packet data services to the UE. Background technique [0002] figure 1 is a diagram schematically illustrating the configuration of a general mobile communication system. refer to figure 1 , the mobile communication system—that is, the Universal Mobile Telecommunications System (UMTS) mobile communication system—includes a Core Network (CN) 100 , a plurality of Radio Network Subsystems (RNS) 110 and 120 , and a User Equipment (UE) 130 . Each of the RNSs 110 and 120 includes a radio network controller (RNC) 111 and 112 and a number of Node Bs 113-116 (ie, base stations). For example, RNS 110 includes RNC 111 and Node Bs 113...
