Multimedia broadcast/multicast service announcement and notification
First Claim
1. A method for transferring a service announcement of Multimedia Broadcast/Multicast Service (MBMS) comprises the following steps:
- (a) Broadcast/Multicast Service Center (BM_SC) requests Cell Broadcast Center (CBC) to send a Service Announcement message, wherein said request may include sending times and sending time duration as parameters;
(b) After receiving a message from the BM_SC, the Cell Broadcast Center (CBC) commands UMTS Terrestrial Radio Access Network (UTRAN) connected with it by a message to send the service announcement;
(c) UMTS Terrestrial Radio Access Network (UTRAN) arranges the time for sending the Multimedia Broadcast/Multicast Service (MBMS) service announcement message at one or more schedule periods according to the requirement of Cell Broadcast Center (CBC), adds a brief description information to a schedule message that describes each of the schedule periods and sends the schedule message;
(d) UMTS Terrestrial Radio Access Network (UTRAN) sends the Multimedia Broadcast/Multicast Service (MBMS) service announcement message.

Abstract
The present invention proposes a method of making use of Cell Broadcast to support MBMS transfer service announcement or service notification transfer. The method of transferring service announcement comprises the following steps: CBC commands UTRAN connected with it by a signaling message to send service announcement; UTRAN arranges the prescribed time of sending MBMS service announcement message, adds the brief description information to the schedule message and sends the schedule message; after receiving the schedule message, UE configures physical layer thereof to prepare for receiving MBMS service announcement message. UTARN sends MBMS service announcement message at the prescribed time.
