Abstract
Abstract The present invention is related to a method and system for multicast service announcement in a cell that includes a core network, a UTRAN, and one or more mobile network nodes. The UTRAN includes a RNC. The RNC continuously sends multicast service announcements in a frame over a channel such as a PICH. The frame may include a type field and an indication field where the type field contains information related to the type of information in the indication field, or the frame may include a current service announcement identification field, a next service announcement identification field, and a time offset field. The type field can be used also to separate long term scheduling announcement or service advertising frames from the multicast/broadcast data frames, or the type field can be used to separate the multicast/broadcast control frames from the multicast/broadcast data frames.
