Embodiment Construction

[0128] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0129] In LTE, as long as there is a service, it can transmit without any monitoring rules; then the WiFi device in the unlicensed frequency band cannot transmit when LTE has service transmission, and can only detect the channel idle state when the LTE service transmission is completed. to be transmitted. LTE directly using the frequency band where WiFi is located will cause great interference to WiFi. Therefore, when LTE uses unlicensed ...

Abstract

The embodiments of the invention disclose an access control method, an access device and a terminal device. The method is realized through the following steps: a first access device establishing communication connection with a second access device; the first access device obtaining first received signal strength indication (RSSI), wherein the first RSSI is RSSI of a target frequency range, obtained from the second access device, and the target frequency range belongs to a frequency range where the second access device provides service and comprises an unauthorized frequency range; the first access device measuring the target frequency range so as to obtain third RSSI: and according to a ratio of the first RSSI to the third RSSI, determining whether to access the terminal device to the target frequency range. According to the invention, when the unauthorized frequency range is used by use of licensed assisted access, interference caused to terminal devices in the unauthorized frequency range can be avoided.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to an access control method, access equipment and terminal equipment. Background technique [0002] With the rapid increase of communication traffic, the spectrum licensed by the Third Generation Partnership Project (Third Generation Partnership Project, 3GPP) is increasingly insufficient to provide higher network capacity. In order to further improve the utilization of spectrum resources, 3GPP is discussing how to use unlicensed spectrum, such as 2.4GHz and 5GHz frequency bands, with the help of licensed spectrum. These unlicensed spectrums are currently mainly used by wireless fidelity (Wi-Fi), Bluetooth, radar, medical and other systems. 3GPP proposes a concept of Licensed Assisted Access (Licensed Assisted Access, LAA) to use unlicensed spectrum with the help of Long Term Evolution (Long Term Evolution, LTE) licensed spectrum. The unlicensed spectrum is th...
