Description

Distributed home base station, pre-unit and post-unit of distributed home base station

technical field

Embodiments of the present invention relate to communication technologies, and in particular to a distributed home base station, a pre-unit and a post-unit of the distributed home base station.

Background technique

With the continuous development of mobile communication technology, the application of mobile network is more and more extensive.

Due to the large transmission loss and space loss of wireless signals, and the weak ability to penetrate the walls of buildings, the indoor coverage of mobile communication networks is often unsatisfactory. Although users access mobile networks through mobile terminals, most services, especially high-speed data services and multimedia services, mostly occur indoors. It is particularly important to ensure the coverage of indoor wireless signals. To improve the coverage of indoor wireless signals, a wireless network device, such as a wireless router, may be installed indoors to provide wireless signals indoors through a wireless fidelity (WIreless-Fidelity, WIFI for short) technology.

However, when the wireless signal is transmitted through the WIFI technology, the wireless signal between the wireless network device and the user equipment (User Equipment, UE for short) is usually permanently encrypted according to a key configured by the user. Since the fixed key is easily obtained by an attacker, this makes the transmission of wireless signals through WIFI technology less secure.
