Abstract
Multiple carriers are used to provide access to a wireless communication system. A first carrier transmits synchronization messages in accordance with the IS-95B standard (communication protocol revision 5). The synchronization message directs mobiles attempting to access the network to a paging channel on the first carrier. The paging channel enables mobiles conforming to a standard of IS-2000 revision 0 or older to access the wireless network. The paging channel also includes an extended global service redirection message (EGSRM) that instructs mobiles conforming to the IS-2000 revision A standard (communication protocol revision 7) to use a synchronization channel on a second carrier for reception of an IS-2000 revision A synchronization message. The IS-2000 revision A (communication protocol revision 7) synchronization message instructs the mobile to access the wireless communication network using a BCCH and/or FCCCH on the second carrier, or using a BCCH and/or FCCCH on the first carrier.
