2.Vehicle Terminal and Service Center" Compared with GB/T 30290.2-2013, the main technical changes in the "Information Exchange Protocol" are as follows, apart from structural adjustments and editorial modifications.

a) Added the terms "message," "business ID," "terminal ID," "business data," "big-endian mode," and "inflection point compensation" and their definitions (see 3.1). 3.2, 3.3, 3.4, 3.5, 3.6);

b) The terms "central center," "branch center," "location information type," "real-time location status," "real-time location refresh parameters," and "real-time positioning" have been removed. "Location validity period", "Real-time location time", "Number of real-time location records", "Real-time location cycle", "Real-time location distance" and "Real-time location duration" "Gap" and its definition (see sections 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, and

3.11 in the.2013 edition);

c) Added symbol descriptions such as GM and UM (see 4.1), and added CAN, CoAP, IP, MQTT, TCP, TTS, UDP, etc. Abbreviations such as VIN, VISC, VISSN, and VT (see 4.2);

d) The term "System Reference Model" was changed to "Reference Model," and the corresponding content was modified (see Chapter 5, Chapter 5 of the.2013 edition);

1 Scope

GB/T 30290.2-2025 is the Chinese national standard covering the protocol between the box in the truck and the centre - the message set and its encoding, the registration and authentication, the position reporting strategy and the buffering when the link is down, and the commands the centre may send back. At 20,000 words. Part 2 of the series. It replaces GB/T 30290.2-2013, in force from 1 February 2026. Issued on 5 October 2025, it has been in force since 1 February 2026, replacing GB/T 30290.2-2013.

This document specifies the information exchange protocol between the vehicle-mounted terminal and the information service center in the BeiDou satellite positioning vehicle information service system. The agreement includes a reference model, protocol description, message structure, and business data format. This document applies to applications using BeiDou satellite positioning technology, employing public or dedicated mobile communication networks, and possessing vehicle information.
