Methods for allocating dispatch service areas of a trunking system based on code division multiple access technology, including assigning groups of a fleet to dispatch service areas formed from non-overlapping dispatch location areas on the push-to-talk register of a trunking system. The assignment information is shared between the network, the mobile station, and the base station to control the trunking conversation of the mobile station.

Method of setting the dispatch area based on the cluster system of CDMA technology

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.
