Problems solved by technology

If the broadcast channel assignment message is still sent using the usual method of sending a channel assignment message in a certain time slot, the called terminal that does not monitor the time slot will not receive the broadcast channel assignment message, and thus cannot establish a broadcast group. Channel resources for calling services
In addition, even if all the called terminals can listen to the broadcast channel assignment message sent by the fixed time slot, since the base station will not continue to send the broadcast channel assignment message after sending the broadcast channel assignment message, those terminals that join later or exit abnormally will not be able to receive the broadcast channel assignment message. Channel assignment message, so that the broadcast group call service cannot be entered
Currently, there is no effective solution to this problem

Embodiment Construction

[0032] The broadcast channel assignment message sending method of the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods, taking a CDMA-based trunking system as an example.

[0033] FIG. 1 depicts a schematic flowchart of a method for sending a broadcast channel assignment message in a CDMA cellular trunking communication system according to the present invention.

[0034] Step 101, start, the broadcast group call service is established, and channel resources are allocated successfully.

[0035] Step 102, on the base station side, the Layer 3 module encapsulates the content of the broadcast channel assignment message into a broadcast channel assignment message for air interface transmission, where the air interface is the air interface, the Um interface, and the air interface transmission means transmission on the Um interface. The content of the broadcast channel assignment message is mai...

Abstract

The present invention relates to a broadcast channel assignment message transmitting method in CDMA assembly communication system, used for transmitting broadcast channel assignment message to broadcast group calling service each called terminal. It features adopting continue transmitting and cycle transmitting combined transmit mode transmitting said broadcast channel assignment message in paging channel, wherein said continue transmitting mode being continue transmitting said broadcast channel assignment message in multiple time slot of one paging time slot cycle, said cycle transmitting mode being using one defined cycle to proceed cycle transmitting said broadcast channel assignment message. The present invention raises systematical reliability.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for sending a broadcast channel assignment message of a CDMA system trunking communication system. Background technique [0002] In the CDMA trunking communication system, the broadcast group call service can share the service channel through the forward and reverse links, which can realize the support of unlimited capacity for a single group call under a single carrier, thus supporting emergency and user concentration conditions. Command and dispatch functions. [0003] On the base station side, after the resource allocation of the forward and reverse shared service channel requested by the broadcast group call service is successful, the base station notifies all called terminals under the sector of the shared resource allocated by the broadcast group call service by sending a broadcast channel assignment message on the paging channel. Channel resource allocation. ...
