Problems solved by technology

[0010] A terminal device using both LTE / UMTS and WLAN, when the frequency interval between the operating frequency used by the LTE / UMTS sub-device and the operating frequency used by the WLAN sub-device is small, the reception of WLAN beacons may be blocked by the LTE / UMTS sub-device. The data transmission of UMTS sub-device is interfered, resulting in the failure of receiving beacons, and even causing the WLAN sub-device (STA) to lose synchronization with the AP, and the quality of WLAN communication is degraded, which ultimately affects user experience.

Abstract

The invention discloses a processing method and a terminal device for avoiding a WLAN (wireless local area network) beacon, which are used for solving the problem of interference between a WLAN beacon signal and a signal of a first type sub-device when the frequency interval between the working frequencies used by the first type sub-device and a WLAN sub-device is very small in the terminal device simultaneously supporting a first type technology (LTE (long term evolution) and / or UMTS (universal mobile telecommunications system) technology) and the WLAN technology. In the processing method of the invention, after the first type sub-device obtains a beacon processing timing sequence information of the WLAN sub-device, a base station configures the beacon processing time for the first type sub-device or the first type sub-device sets the beacon processing time by itself, and the first type sub-device stops transmitting and / or receiving data within the beacon processing time. The processing method and the terminal device can effectively ensure the correct receiving of the WLAN beacon in the terminal device supporting both the LTE technology and the WLAN technology, or guarantee that the first type sub-device cannot be affected when transmitting the WLAN beacon, thereby ensuring the communication quality of the LTE and the WLAN.

Description

technical field [0001] The present invention relates to wireless communication technology, especially to a kind of when LTE or UMTS and WLAN coexist in a terminal device, that is, when the terminal device supports both LTE or UMTS technology and WLAN technology, the WLAN beacon (beacon) receives or sends The LTE or UMTS avoid WLAN beacon processing method and terminal equipment within a certain period of time. Background technique [0002] WLAN (wireless local area networks, wireless local area network) is a widely used communication technology in the field of wireless communication. WLAN is based on the IEEE802.11 standard and uses the unauthorized "Industrial Scientific and Medical (ISM)" A frequency band, such as a 2.4GHz-2.5GHz frequency band. WLAN technology is currently used in many communication electronic devices, such as mobile phone (mobile phone, mobile computer), computer (laptop, portable computer), etc. These communication electronic devices are collectively r...
