A mobile terminal shielding method and interference base station

Abstract

The embodiment of the invention discloses a mobile terminal shielding method and an interference base station. The method comprises the following steps: if the interference base station judges that the shielding triggering condition is satisfied, the shielding control parameter and the shielding service type corresponding to the target area are obtained; replacing the initial control parameter inthe broadcast message with the shielding control parameter, and sending the broadcast message to the mobile terminal in the target area so that the mobile terminal in the target area preferentially selects the interfering base station to establish the communication connection; if the access request sent by the mobile terminal according to the shielding control parameter is received, the access request corresponding to the mobile terminal in the shielding terminal whitelist is responded to according to the preset shielding terminal whitelist, and the mobile terminal is shielded according to theshielding service type after the communication connection is established. By applying the scheme of the invention, the service shielding of the mobile terminal to be shielded can be realized and thecommunication interference to the mobile terminal without shielding can be reduced at the same time.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of mobile communication, and in particular to a mobile terminal shielding method and an interfering base station. Background technique [0002] With the continuous development of mobile communication technology, the leakage of mobile phone communication has also attracted much attention. Due to the openness of the wireless channel, as long as the corresponding receiving equipment is used, the communication information of the mobile phone can be intercepted, and it can be positioned, tracked and monitored. However, in special environments such as confidential conference rooms, prisons, important national governments, and military departments, in order to prevent leakage of mobile phone communication, it is not desirable to carry out mobile phone communication. For this reason, the signal shielding device can be used to cut off the connection between the mobile phone and the base sta...

Problems solved by technology

[0005] However, since the interference signal has a certain coverage area, when the shielding device interferes with the known signal to be shielded and transmits a high-power interference signal, the wireless signal transmitted by the mobile terminal that does not need to be shielded within the coverage area of ​​the interference signal will also be affected. The influence of the interference signal makes the base station unable to demodulate the wireless signal transmitted by the mobile terminal without shielding

[0006] Therefore, in the existing shielding scheme based on the interference signal, the high-power interference signal blocks the communication between the mobile terminal and the base station in the shielding area, and at the same time interferes with the normal communication between the mobile terminal and the base station that do not need to be shielded. , thereby degrading the quality of service for end users who do not need shielding
