Problems solved by technology

For example, there are 16 time slots, each 20MS, then a total of 320MS, assuming that the BCAM is sent to the called terminal in the first time slot, and a called terminal is fixed to monitor the 10th time slot, then it will be in the 200MS Access to group calls, so the called terminal's access speed is relatively slow, and it may not be able to access the group call at the first time after receiving the BCAM; moreover, if the fixed monitoring time slots of multiple called terminals are different, it will cause The times when multiple called terminals access the group call are inconsistent, sometimes fast and sometimes slow. The time difference between fast access and slowest access is 300MS, which seriously affects the quality of group calls

Embodiment Construction

[0027] The present invention will be further described in detail below through specific embodiments and accompanying drawings.

[0028] The core idea of ​​the present invention is: to propose a called paging method applicable to the trunking communication system, after the network side of the trunking communication system receives the calling message from the calling terminal, it sends a BCAM without resources to the called terminal , and perform authority authentication; after the authority authentication is passed, the network side establishes corresponding resources, and issues BCAM with resources to the called terminal.

[0029] The BCAM without resources means that the BCAM does not include channel resource information established by the base station. The BCAM with resources means that the BCAM includes channel resource information established by the base station, and the terminal can access the network and join a group call according to the channel resource information. ...

Abstract

The invention discloses a method for paging a called party, which is applied to a cluster communication system. The invention is characterized in that the method includes the following steps: A. afterreceiving calling information from a calling terminal, a side of system network delivers the information for paging the called party without resource to the called terminal, and identifies the authority; B. after the authority identification passes, and corresponding resources are created, the side of system network delivers the information of paging the called party with resource to the called terminal. The invention can improve the access speed of the called party as well as the paging quality.

Description

technical field [0001] The invention relates to the trunking communication technology, in particular to a called paging method suitable for the trunking communication system. Background technique [0002] At present, trunking communication technology is becoming more and more mature and developing, and has been widely applied to various industries. In an existing trunking communication system, such as a Code Division Multiple Access (CDMA) trunking communication system, the following schemes are mainly adopted for called paging. [0003] figure 1 It is a flow chart of a called paging method in an existing CDMA trunking communication system. see figure 1 , the calling terminal first sends the trunking calling message for the group call to the base station on the system network side, and then the base station sends the trunking calling message to the trunking scheduling server on the system network side; Authority authentication; after the authority authentication is passe...
