LTE mobile communication terminals support Beidou positioning Test Method

1 Scope

GB/T 44195-2024 gives the test methods for LTE mobile terminals that support BeiDou positioning. A phone's positioning performance is not a property of its GNSS chip alone: it depends on the antenna sharing space with the cellular radios, on the interference the transmitter generates while the receiver is trying to acquire, and on the assistance data the network supplies, which is why positioning has to be tested on the terminal in a cellular test environment rather than on the receiver in isolation. The standard sets the test conditions, including the test environment and the test system, then the RF minimum performance tests for autonomous positioning - GPS, BeiDou, and BeiDou/GPS dual mode - and for network-assisted positioning in the same three configurations, covering sensitivity, accuracy and time to first fix under the specified signal conditions, together with the protocol conformance aspects of the assistance data. It took effect on 1 November 2024.

This document describes the test method for mobile communication terminals to support BeiDou positioning based on LTE control plane, involving support for BeiDou positioning on the control plane Protocol testing of LTE terminals, network-assisted Beidou positioning performance testing, and performance testing that supports autonomous Beidou positioning. This document is applicable to the design, development and maintenance of LTE Phase 3 and above mobile communication terminals (hereinafter referred to as "terminals") that support Beidou positioning. Development, production and testing.
