Problems solved by technology
[0004] Since multiple base stations need to send paging messages with preambles within their respective ranges when searching for the second terminal, the waste of preambles is caused, and the wasted preambles cannot be used by other paging messages within a period of time. Paging applications, affecting the random access channel performance of other terminal equipment in the base station

Embodiments of the present invention disclose a method, device and system for terminal equipment discovery, relate to the field of communication technologies, and solve the waste of preamble code caused when searching for a second terminal equipment, which affects the random access channel performance of other terminal equipment in the base station The problem. The method includes: the first terminal device acquires the information of the synchronization signal of one or more cells next to the base station where the first terminal device or the second terminal device is located, and detects the synchronization signal information of the one or more cells according to the information of the synchronization signal of the one or more cells. The synchronization signal sent by the second terminal device, and the strength of the synchronization signal is obtained to discover the second terminal device through the synchronization signal, and the synchronization signal sent by the second terminal device is the one or more One of the synchronization signals of each cell. The present invention is suitable for use in mobile networks.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for discovering terminal equipment. Background technique [0002] At present, it is a waste of wireless resources to transmit information of two terminal devices with close distances in the network through an evolved base station (Evolved NodeB, eNodeB for short). For example, when transmitting the same amount of data, when two devices with close distances can communicate directly, half of the wireless resources can be saved compared to the communication method transmitted through the base station. This method in which two devices with close distances directly communicate is called device-to-device (D2D for short). Two terminal devices in D2D communication use spectrum resources from the wireless communication network. With the continuous development of smart phones, more and more user devices require short-distance data transmission, ...
