Abstract

The embodiment of the invention discloses a method and a system for device-to-device communication on a wireless local area network frequency band. The method comprises the following steps: a base station receives a D2D communication request message reported by a first mobile terminal, determines the configuration information of a WiFi module for processing a communication service on the WLAN frequency band according to the WiFi module information of the first mobile terminal and a second mobile terminal while determining that the communication service between the first mobile terminal and the second mobile terminal is processed on the WLAN frequency band, indicates one of the first mobile terminal and the second mobile terminal to initiate an IBSS on the basis of the configuration information of the WiFi module, and notifies the other mobile terminal to join the IBSS, so that the first mobile terminal and the second mobile terminal establish WiFi connection and process the communication service on the WLAN frequency band through D2D communication according to the configuration information of the WiFi module. The method and the system disclosed by the embodiment of the invention are capable of avoiding occupying the authorized frequency bands of the traditional cellular network, and generating interference on the traditional cellular communication service.

Description

Technical field [0001] The present invention relates to communication technology, in particular to a method and system for device-to-device (D2D) communication on a wireless local area network (Wireless Local Area Network, WLAN) frequency band. Background technique [0002] With the rapid development of wireless communication technology, wireless spectrum resources are becoming more and more scarce, but at the same time, users have higher and higher requirements for network speed and network coverage continuity, so how to achieve high speed in limited bandwidth resources Wide coverage has become very important for operators. A new type of D2D communication technology is being discussed in Release 12 of the 3rd Generation Partnership Project (the3rd Generation Partnership Project, 3GPP). Such as figure 1 As shown, it is a schematic diagram of a principle of D2D communication technology in a Long Term Evolution (Long Term Evolution, LTE) network. Such as figure 1 As shown, throug...
