Title: TERMINAL DEVICE POSITIONING METHOD AND NETWORK DEVICE
Abstract:
The embodiments of the present application provide a terminal device positioning method, for realizing the positioning of a terminal device in an NB-IoT. The terminal device positioning method provided in the present application comprises: a first network device determining the NPRACH parameter of a terminal device, the NPRACH parameter being used for representing the manner of the first network device scheduling the terminal device to send an NPRACH signal multiple times. The first network device sends a first message to a second network device, the first message comprising the NPRACH parameter, the first message being used by the second network device to locate the terminal device. In the invention, the first network device informs the second network device of the NPRACH parameter so that the second network device in the NB-IoT can locate the terminal device according to the NPRACH parameter, improving NB-IoT user experience, which will assist in popularizing the NB-IoT network. The present application further provides a related network device.
