Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] A kind of PDT police digital trunking terminal satellite positioning data reporting method, it comprises the following steps:

[0044] (1) The scheduling terminal selects the target user group, and then initiates a satellite positioning data pull-up request to the PDT system; each user group includes at least one user terminal, and the user terminal in the target user group is the target terminal, and each user group Each has a unique group number and group address, and each user terminal has a unique identification number, personal number and personal address;

[0045] (2) After the PDT system receives the pull-up request initiated by the dispatching terminal, it analyzes the pull-up request and encapsulates one or more positioning data pull-up group short messages;

[0046] (3) The PDT system sends a satellite positioning da...

Abstract

The invention discloses a PDT police digital trunking terminal satellite positioning data reporting method, and belongs to the technical field of wireless communication. According to the method, batchpull-up processing is carried out on the target terminals by adopting a mode of pulling up the group short messages by the positioning data, so that the number of pull-up signaling needing to be issued is greatly reduced, the reporting period is shortened to a greater extent, and more target terminals can be supported to report the positioning data within the same time. The method has good expansibility and stability, can effectively avoid service collision generated when the terminal reports the satellite positioning data at the same time, can shorten the reporting period to a great extent,supports more terminals to report the positioning data, and can effectively ensure normal operation of other services in the reporting process. The patent is benefited by the national key research anddevelopment plan, and the project number is 2017YFC0821900.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method for reporting satellite positioning data of a PDT police digital trunking terminal. Background technique [0002] The PDT (Police Digital Trunking) standard protocol defines three satellite positioning data reporting methods, which are as follows: [0003] 1. GPS single pull-up, the authorized wired dispatching terminal sends a pull-up request to the system, the system sends a pull-up command to the target terminal according to the request, and the target terminal reports the satellite positioning data as a short message through the control channel. [0004] 2. Pull up the dedicated data channel. The authorized wired dispatching terminal subscribes to the system for the satellite positioning data of the designated target terminal and the pull-up period. After the subscription is successful, the system automatically sends the pull-up command to ...
