Embodiment Construction

[0063] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0064] The broadband digital trunking communication system is technically based on LTE. In addition to maintaining the basic structure of the original system, the trunking function is added. For this reason, compared with ordinary LTE, trunking-related processes are added at the system level, and at the physical level Three downlink channels of TPCCH, TCCH and TTCH are provided.

[0065] Wherein, the TPCCH is used to bear the cluster paging message, the TCCH is used to bear the cluster control signaling, and the TTCH is used to bear the downlink cluster service data.

[0066] TPCCH information is scrambled by TP-RNTI for transmission on the TPCCH channel, and information scrambled by G-RNTI is used for T...

Abstract

The application provides a broadband digital trunking group call method and a device, in order to solve the problem that a trunking terminal has large burden in supporting the digital trunking function and has large consumption in detecting data. The method comprises receiving a group call paging message sent by a trunking paging control channel, and constructing the group call connection; monitoring a physical downlink control channel at each transmission time interval, and acquiring the sending period and the sending time moment of the trunking control channel in a group call establishing message if receiving the group call establishing message on the trunking control channel; setting the sending period of the trunking control channel as the detection interval, and setting the sending time moment as the detection time moment; and monitoring the physical downlink control channel at each detection interval from the detection time moment, and receiving the group call data, which includes the group call establishing message. The application can reduce the burden of the trunking terminal as well as the consumption of the trunking terminal during data detection.

Description

technical field [0001] The present application relates to the field of trunking technology, in particular to a group call method and device for broadband digital trunking. Background technique [0002] With the development of mobile communication, mobility and broadband have become the development trend of the industry. Under such a background, digital trunking, that is, a dedicated mobile communication system has also begun to develop in this direction. After the bandwidth is increased, it can provide higher transmission rate, clearer image and video, and better user experience. [0003] TD-LTE (Time Division Long Term Evolution) is one of the most cutting-edge mobile broadband technologies, and already has mature technical specifications and mature products. As the transmission technology of the cluster system, TD-LTE can provide cluster customers with a higher transmission rate than the previous narrowband system. After adding cluster-specific functions to the TD-LTE sy...
