Abstract:
According to an Evolved Multimedia Broadcast Multicast Service (E-MBMS) service method of the present invention, an E-MBMS service is received from a first base station. If neighbor cell MBMS control information is modified in the first base station, MBMS paging information, including a factor informing that the neighbor cell MBMS control information has been modified, is received from the first base station. When an MBMS control information update cycle is reached, modified neighbor cell MBMS control information is received from the first base station and is stored. When a user equipment moves from the first base station to a second base station, a P-T-M radio bearer is reset based on the stored neighbor cell MBMS control information and receiving the E-MBMS service from the second base station. Accordingly, the consumption of battery power can be reduced, and an E-MBMS service being services is not interrupted although a user equipment moves.
