Description
Technical Field
The embodiment of the invention relates to the field of communication, in particular to a cooperative shielding method, a data shielding method, a host shielding device, a slave shielding device, a shielding system, a storage medium and an electronic device.
Background
At present, when signal shielding is performed, shielding equipment is generally arranged in a target area, and the shielding equipment interferes signals and data sent by a base station or signal transmitting equipment, so that signal shielding is realized.
However, in some communication systems, the mask time slot of the mask is limited; for example, in a TDD (Time Division duplex) system, a masker is not allowed to transmit a shielding signal in an uplink Time slot, otherwise, the operation of the whole base station is interfered, so that the masker is required to transmit an interference signal in most of the shielding Time period and not transmit the interference signal in a very short Time when performing a shielding operation, and in the very short Time, the masker is further required to be able to receive a downlink signal of the base station and analyze the uplink and downlink Time slots of the base station, so as to implement a function that the masker only interferes with the downlink Time slot of the base station.
In most cases, a single shielding device can only shield a certain range of area, and multiple shielding devices are needed to shield areas beyond the range. When a plurality of shielding devices work simultaneously, at the moment that any shielding device transmits an interference signal, other shielding devices cannot receive a downlink signal transmitted by the base station, so that uplink and downlink time slots of the base station cannot be analyzed, and further, other shielding devices cannot execute a normal shielding function, and the shielding effect is influenced.
However, no technical solution for effectively solving the above problems is available at present.
