Abstract:
1. A method for acquiring Multimedia Broadcast/ Multicast Service (MBMS) access information, comprising: in a modification period of MBMS Point to Multipoint Control Channel (MCCH) information, upon receiving an MBMS access information transmitted from a network, a User Equipment (UE) initiating a responding procedure to respond to the MBMS access information according to current state of the UE; and the UE judging whether the UE responds to the MBMS access information successfully, if yes, the UE stopping receiving further MBMS access information in the modification period of MCCH information; if not, the UE continuing acquiring further MBMS access information in the modification period of MCCH information; wherein the MBMS access information transmitted from network comprises a probability factor for the MBMS activated by the UE; before the UE initiating the responding procedure, further comprising: upon receiving the MBMS access information that comprises the probability factor, the UE generating a random number uniformly distributed within [0, 1]; and judging whether the generated random number satisfies an assigned initiating condition, upon comparing the generated random number with the probability factor comprised in the MBMS access information, if yes, the UE initiating the responding procedure according to the state of the UE, if not, the UE continuing acquiring the further MBMS access information in the modification period.
