METHOD AND DEVICE FOR RECEIVING A MULTIMEDIA BROADCAST MULTICAST SERVICE IN A MOBILE COMMUNICATION SYSTEM
First Claim
1. A method by a terminal in a wireless communication system, the method comprising:
- receiving, on a first cell, information indicating a duration related to a random access response (RAR) through system information;
receiving, on the first cell, a maximum number of preamble transmissions for a random access of a second cell through control information;
transmitting a random access preamble for the random access of the second cell based on the maximum number of preamble transmissions; and
receiving the RAR based on the information.

Abstract
The present disclosure relates to a method and device for receiving a multimedia broadcast multicast service (MBMS) in a mobile communication system. The method for receiving the MBMS of a terminal in the mobile communication system according to an embodiment of the present disclosure is characterized in that it includes: determining whether service area ID (SAI) information on a serving cell is broadcast during the MBMS; receiving the SAI information on the serving cell when it is determined that the SAI information is broadcast; determining, by using the received SAI information of the serving cell, whether an SAI of the MBMS matches the SAI of the serving cell; and changing the cell reselection priority of the frequency of the serving cell to the highest priority if it is determined that the SAI of the MBMS matches the SAI of the serving cell.
