Document Type and Number:
WIPO Patent Application WO/2007/028274
Kind Code:
A1
Abstract:
A method of establishing a call quickly in CDMA trunked communication includes the
following steps: on forward common channel, transmitting broadcast paging message
with a group identifier with which user terminal performs matching; on reverse
common channel, establishing dynamic access channels, and releasing these
dynamic access channels immediately after completing call access phase. The
method of the present invention can not only save on-the-air link resources, but
also improve call connection speed when group user terminals are crowded, and
solve the problem that connection time is too long in existing CDMA public network
trunked system. Practical test shows that connection time is whithin 3 seconds
in the case of 60 users in a single sector.
