Embodiment Construction

[0033] The process for the terminal to report GPS positioning information is as follows: figure 2 shown, including the following steps:

[0034] Step 201, the system sends SDB signaling to the terminal in the group call;

[0035] Step 202, after receiving the SDB message, the terminal checks the message, if the check passes, executes the next step, otherwise, ends;

[0036] After receiving the message from the system, the terminal first decodes the message in accordance with the "CDMA Technology-Based Digital Trunking System Interface Technical Requirements--Air Interface" to obtain the content of the relevant message, and judge whether it is a GPS system positioning-related SDB message (for example, through the message header Whether it is 0x1C to judge), if yes, continue to check the SDB message, otherwise end.

[0037] The terminal verifies the SDB message through the verification code carried in the message. In other embodiments, the verification operation may not be pe...

Abstract

The invention discloses a digital group system terminal and a method for reporting GPS positioning information thereof, realizing GPS positioning information reporting of the terminal. The method comprises the following steps: when a system requires the terminal to report GPS positioning information, the terminal reports to the system after constructing the self GPS positioning information into short data burst SDB information. The terminal comprises a GPS module and a terminal control module, wherein the GPS module is used for receiving the order that the system requires the terminal to report the GPS positioning information, and reporting the GPS positioning information of the terminal to the system; the terminal control module is used for collecting self GPS positioning information after receiving the order that the system require to report the GPS positioning information, wherein the terminal control module constructs the collected GPS positioning information into the SDB information when being in a group communication state and reports to the system by PTTGPS positioning response information.

Description

technical field [0001] The invention relates to the field of digital trunking communication systems, in particular to a method for realizing the terminal GPS positioning function in the digital trunking communication system and a data trunking communication system terminal. Background technique [0002] The digital trunking communication system is an important branch of the mobile communication system, and it is a mobile communication system applied to group dispatching and command communication. Mainly used in the field of professional mobile communications, such as government departments, military, police, railways, water conservancy, civil aviation and steel logistics and other industries. [0003] The network structure of the digital trunking communication system (such as figure 1 ), mainly including the trunking terminal 1, the base station subsystem 2, and the dispatching subsystem 3, wherein: [0004] Cluster terminal 1, a terminal device with cluster service functi...
