Method of notifying MBMS service information of a neighboring cell and corresponding apparatus

A method in a base station comprising:

• transmitting, in a system information block SIB, which is independent of a SIB 13, to the user terminal the multimedia broadcast multicast service MBMS service information of the at least one neighboring cell;
• indicating to the user terminal a change of the multimedia broadcast multicast service MBMS service information of the at least one neighboring cell included in the system information block SIB by setting bits in a downlink control information DCI format IC to be all zero;
• transmitting to the user terminal an updated edition of the system information block SIB so as to notify the user terminal of the change of the multimedia broadcast multicast service MBMS service information of the at least one neighboring cell, wherein the multimedia broadcast multicast service MBMS service information of the at least one neighboring cell comprises a carrier frequency and a list of an identifier of an MBMS service supported at the carrier frequency;
• and
• transmitting to the user terminal, through a system information block, notification configuration information which is used to notify the user terminal of occasion and period for notifying the change of the multimedia broadcast multicast service MBMS service information of the at least one neighboring cell included in the system information block SIB.

A method in a user terminal comprising:

• receiving, in a system information block SIB, which is independent of a SIB 13, from the base station the multimedia broadcast multicast service MBMS service information of the at least one neighboring cell, wherein the multimedia broadcast multicast service MBMS service information of the at least one neighboring cell comprises a carrier frequency and a list of an identifier of an MBMS service supported at the carrier frequency;
• determining whether the multimedia broadcast multicast service MBMS service information of the at least one neighboring cell included in the system information block SIB is changed by determining whether bits in a downlink control information DCI format 1C are set to zero;
• receiving from the base station an updated system information block SIB to notify the user terminal of the multimedia broadcast service MBMS service information of the at least one neighboring cell;
• and
• receiving from the base station through a system information block, notification configuration information which is used to notify the user terminal of occasion and period for notifying the change of the multimedia broadcast multicast service MBMS service information of the at least one neighboring cell included in the system information block SIB.
