Abstract

The invention provides a device, method and system for shielding communication between a terminal and a base station, relating to a mobile communication technology and aiming at solving the problem of large transmitting power of a radio signal shielding device in the prior art. The method for shielding communication between the terminal and the base station comprises the steps that: a shielding device acquires identification of at least one network cell to be shielded; the shielding device acquires the configuration information of a physical random access channel (PRACH) of the network cell according to the identification of the network cell; and the shielding device sends a random access preamble on each PRACH of the network cell according to the configuration information of the PRACH so as to block the PRACH. The invention has the advantages of lowering power consumption and meeting the environment protection requirement.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a device, method and system for shielding communication between a terminal and a base station. Background technique [0002] In the field of mobile communication technology, wireless signal shielding devices are often required. Taking WCDMA as an example, the main principle of the wireless signal shielding device of the current WCDMA (Wideband Code Division Multiple Access) system is: use a high-power transmission frequency on the base station side or the terminal side to transmit interference signals, so that The radio frequency receiving unit of the base station or terminal cannot obtain correct information from the received wireless signal. [0003] In order to be able to suppress the wireless signal of the base station or terminal, the wireless signal transmission power of the shielding device must be large enough to ensure that the signal power of the base station and term...
