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.
