ABSTRACT:
A method of providing a list of digital control channel (DCCH) frequencies that are in use in a radio telecommunications network to a mobile station operating in the network. Each DCCH includes a superframe having an extended broadcast control channel (E-BCCH) time slot which is broadcast in an E-BCCH cycle. The method begins by dividing the list of DCCH frequencies into a plurality of DCCH subsets, and sequentially or randomly broadcasting the DCCH subsets to the mobile station in the E-BCCH time slot of the DCCH. The next DCCH subset is broadcast when the current E-BCCH cycle is completed. Alternatively, the next DCCH subset may be broadcast when a timer expires. In this case, a broadcast control channel (BCCH) change notification (BCN) indicator is changed whenever a new subset is broadcast. A DCCH Frequency Plan message is added to IS-136, and includes a DCCH subset, an associated DCCH Frequency List Subset Sequence Identifier (SSI), and information elements to identify the System Operator Code (SOC) and System Identifier (SID).
