Method and system for a multicast service announcement in a cell

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.

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.
