ABSTRACT:
The present invention discloses a method for improving paging speed of a called user in CDMA trunking system. For a first trunking terminal supporting minus time slot call manner, said method includes: it makes minus time slot paging cycles of the first trunking terminal and a trunking core network keep synchronous; the first trunking terminal selects a minus time slot paging cycle to calculate a paging time slot according to the presence of its own minus time slot paging cycle and the presence of a minus time slot paging cycle contained in an overhead message of a call channel, and monitors the call channel on the calculated paging time slot; the base station system selects a minus time slot paging cycle to calculate a paging time slot of the user according to the presence of its own minus time slot paging cycle and the presence of a minus time slot paging cycle contained in a paging request message, and transmits a paging message on the call channel according to the calculated paging time slot. The method of the present invention effectively shortens the duration of establishment of a trunking call, and simultaneously maintains the compatibility for the existing trunking terminals.
