Patent ID: 8675533

Claim:
A method for determining a radio frame bearing a multimedia broadcast multicast service notification message, comprising: a sending end configuring a Multicast Control Channel (MCCH) Modification Period (MCCHMP), a period coefficient (PeriodCoeff) and a notification message offset (NotificationOffset), and when a system frame number (SFN) modulo a ratio of the MCCHMP to the PeriodCoeff is equal to the NotificationOffset, a radio frame corresponding to a value of said SFN is the radio frame of sending the Multimedia Broadcast Multicast Service (MBMS) notification message; wherein when a cell is only covered by one Multimedia Broadcast multicast service Single Frequency Network (MBSFN) area, a value of said MCCHMP is a value of the MCCH modification period of this MBSFN area; when a cell is in overlapped coverage of a plurality of MBSFNs, the value of said MCCHMP is the value of the MCCH modification period of the MBSFN area with a minimal MCCH modification period among a plurality of MBSFN areas; and said PeriodCoeff denotes a number of times of sending the MBMS notification message in one MCCH modification period.
