Method and system for a multicast service announcement in a cell
First Claim
1. A method for multicast services announcements comprising:
- sending a signaling message containing at least one service announcement identification from a first network node to at least one second network node;
sending multicast service announcements continuously on a channel each multicast service announcement having an associated service announcement identification;
comparing the at least one service announcement identification with multicast service identifications configured in the second node;
checking the multicast service announcements on the channel associated with the at least one service announcement identification that compares with the multicast service identifications; and
receiving, at the second network node, the multicast service announcements associated with the at least one service announcement identification that compares with the multicast service identifications, wherein the at least one service announcement identification comprises one of at least one service identification and at least one multicast group identification.

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.

18. A method for multicast services announcements comprising:
-
sending time information on a first channel, the time information conveying when a list of multicast services will be sent on a second channel;
checking the time information at a first network node;
checking current multicast services sent on a third channel if the time information is not currently available on the first channel;
receiving the current multicast services at the second network node if the second network node is entitled to receive the current multicast services;
checking an offset value time of when a next multicast services will be sent on the third channel if the second network node is not entitled to receive the current multicast services;
receiving the next multicast services at the second network node after the offset value time if the second network node is entitled to receive the next multicast services; and
waiting for the list of multicast services to be sent on the second channel if the second network node is not entitled to receive the current multicast services or the next multicast services. - View Dependent Claims (19, 20, 21, 22, 23, 24)

25. A system for multicast services announcements comprising:
-
a core network;
a Universal Terrestrial Radio Access Network (UTRAN) operably connected to the core network, the UTRAN including at least one Radio Network Controller (RNC), the RNC continuously sending multicast service announcements in a frame over a channel; and
at least one mobile network node operably connected to the UTRAN through the at least one RNC, wherein the frame comprises a type field and an indication field, the type field containing information related to the type of information in the indication field. - View Dependent Claims (26, 27, 28, 29)
