Abstract

The invention discloses a conflict avoiding method for unlicensed bands in an embodiment. The conflict avoiding method comprises the following steps: setting conflict avoidance parameter values of different data types and based on the Listen Before Talk (LBT) mechanism of a load; solving conflict by use of the conflict avoidance parameter values according to the current data type in the unlicensed bands; and sending the conflict avoidance parameter values to user equipment (UE) so that the UE solves conflict by use of the conflict avoidance parameter values according to the current data type in the unlicensed bands. According to the conflict avoiding method for the unlicensed bands of the embodiment, LTE equipment of the unlicensed bands avoids and solves conflict by use of different conflict avoidance parameter values according to the type of the transmitted data so as to ensure that the high-priority service of the LTE equipment can be served preferentially; as a result, the transmission of data of different types can be effectively supported in the unlicensed bands.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for avoiding conflicts in unlicensed frequency band channels. Background technique [0002] With the rapid increase of mobile communication traffic, the licensed frequency bands in the 3GPP network are increasingly unable to meet the increasing traffic volume. In order to further improve the efficiency of frequency resources on the limited frequency resources, 3GPP organizations turn to access to unlicensed frequency bands. For technical research, LTE Assisted Access (LAA) technology is introduced, in order to assist the use of unlicensed frequency bands with the help of Long Term Evolution (LTE) access technology on licensed frequency bands. [0003] The WiFi technology on the unlicensed frequency band eliminates the interference between different WiFi devices through Carrier Sense Multiple Access / Collision Detection (CSMA / CA). Before sending...
