Embodiment Construction

[0042] Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. The order of operations can be rearranged. A process may be terminated when its operations are complete, but may also have additional steps not included in the figure. A process may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0043] Computer equipment includes user equipment and network equipment. Among them, user devices or clients include but not limited to computers, smart phones, PDAs, etc.; network devices include but not limited to a single network server, a server group composed of multiple network servers, or a cloud computing-based network composed of a large number of computers or network servers. cloud. The computer equipment can operate independently to realize the present invention, and can also access the network and realize the present invention through mutual...

Abstract

The invention provides a signal shielding method. The method comprises: the range of frequencies currently being used by the base station is obtained; the location of main sync signal time gap is obtained based on the range of frequencies currently being used by the base station; interference signal is transmitted based on the location of main sync signal time gap. User devices, such as mobile terminal and the like, receive the down going signal sent by the base station in the main sync signal time gap, then the descending synchronization with the base station is obtained. And the user devices meanwhile send the leading code sequence of request random access to the base station in the main sync signal time gap, therefore, transmitting interference signal in the main sync signal time gap enables the user devices not to search the network and communicate normally at the same time. Hence, the method has the advantages that the shielding effect of the signal is enhanced, the power of the signal shielding device is reduced, energy is saved, and radiation to the human body is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a signal shielding method and device. Background technique [0002] With the rapid development of wireless communication technology, mobile terminals such as mobile phones and walkie-talkies are popular among users due to their convenience, speed, and freedom from time and place restrictions. The number of users continues to grow. Various fields such as production play an important role, and have gradually become one of the indispensable tools in people's daily life and work. [0003] But while mobile terminal brings great convenience to people's life, it also produces some problems that cannot be ignored. Due to the wide coverage of the mobile communication network, in some occasions the emergence of the network and the use of mobile terminals have brought troubles to human beings, and even hidden safety hazards, such as: becoming a new source of noise pollution, disturb...
