Method for improving paging speed of a called user in CDMA trunking system
First Claim
1. A method for improving paging speed of a called user in a code division multiple access trunking system characterized in that, for a trunking terminal supporting minus time slot paging manner, comprises the following steps:
- a minus time slot paging cycle synchronizing step, in which minus time slot paging cycles saved by the trunking terminal and a trunking core network are kept synchronous;
a system paging channel monitoring step, in which the trunking terminal decides a time slot paging cycle to calculate a paging time slot according to the presence of its own minus time slot paging cycle and a presence of a minus time slot paging cycle contained in an overhead message of a call channel and monitors the paging channel on the calculated paging time slot; and
a user paging step, in which base station system selects a 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 message, and transmits a paging message on the paging channel according to the calculated paging time slot.

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.

15. A method for improving paging speed of a called user in a code division multiple access thinking system for a first trunking terminal supporting minus time slot paging manner, comprising the following steps:
- a minus time slot paging cycle synchronizing step, in which minus time slot paging cycles made are saved by the first trunking terminal and a trunking core network keeps said cycles synchronous;
a system paging channel monitoring step, in which the first trunking terminal decides a time slot paging cycle to calculate a paging time slot according to a presence of a minus time slot paging cycle of the first trunking terminal and to the presence of a minus time slot paging cycle contained in an overhead message of a call channel, and monitors the paging channel on the calculated paging time slot; and
a user paging step, in which a base station system selects a time slot paging cycle to calculate a paging time slot of a user according to the presence of a minus time slot paging cycle of the base station system and to the presence of a minus time slot paging cycle contained in a paging message, and transmits a paging message on the paging channel according to the calculated paging time slot.
- a minus time slot paging cycle synchronizing step, in which minus time slot paging cycles made are saved by the first trunking terminal and a trunking core network keeps said cycles synchronous;
