Abstract:
1. A method of transmitting a validity of physical channels carrying MBMS (Multimedia Broadcast Multicast Service) data in a wireless communication system, the method comprising: generating an MBMS Modified Service Information (MSI) message comprising validity information for deriving a validity timing of configuration information of the physical channels of at least one cell; and transmitting the MSI message to a mobile terminal through the at least one cell, wherein the validity information is based on at least a least significant bit (LSB) of a system frame number (SFN), wherein the physical channels are Secondary Common Control Physical Channels (SCCPCH), wherein the validity information is a point-to-multipoint activation time for an MBMS service, and wherein the validity information defines a starting time at which the configuration information becomes valid.
