Method and apparatus for interchanging and processing mobile radio subsystem control information
View Patent ↗A wireless communication system ( 100 ) is configured to send signaling messages through a cell broadcast service (CBS). CBS message pages used to transport signaling messages are identified by assigned message identifiers. Mobile devices ( 114 ) within the communication system ( 100 ) recognize the CBS messages transporting signaling messages by the message identifiers and pass the signaling messages to an appropriate application or control program module. The message identifier may be used to specify the application or control program module to process the signaling message. The signaling messages transported by the CBS may be used in controlling a multicasting or broadcasting service. Duplicate copies of the CBS message pages may be transmitted and then buffered at the mobile device ( 114 ) as they are received until all parts of the signaling message have been received.
