Method and device for filtering broadcast data, terminal equipment, and storage medium

Terminal equipment, comprising a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein the processor is configured to, when executing the computer program, perform operations that comprise:

• obtaining a current broadcast message broadcast by the terminal equipment, wherein the current broadcast message comprises current broadcast data;
• performing a signature processing on the current broadcast data to determine signature information corresponding to the current broadcast data;
• comparing the signature information corresponding to the current broadcast message with signature information corresponding to various valid broadcast messages received by the gateway to determine whether a first valid broadcast message being the same as the current broadcast message is presented in the various valid broadcast messages;
• determining, when the first valid broadcast message is presented, that the current broadcast message is a duplicate broadcast message, and discarding the current broadcast message;
• and
• determining, when the first valid broadcast message is not presented, that the current broadcast message is a newly-received valid broadcast message,
• wherein before performing the signature processing on the current broadcast data to determine the signature information corresponding to the current broadcast data, the operations further comprise:
• determining whether the current broadcast message meets a pre-filtering rule;
• and
• discarding the current broadcast message when the current broadcast message meets the pre-filtering rule.

A non-transitory computer-readable storage medium in which a computer program is stored, wherein the computer program, when being executed by a processor, enables the following operations to be performed that comprise:

• obtaining a current broadcast message broadcast by a piece of terminal equipment, wherein the current broadcast message comprises current broadcast data;
• performing a signature processing on the current broadcast data to determine signature information corresponding to the current broadcast data;
• comparing the signature information corresponding to the current broadcast message with signature information corresponding to various valid broadcast messages received by a gateway to determine whether a first valid broadcast message being the same as the current broadcast message is presented in the various valid broadcast messages;
• determining, when the first valid broadcast message is presented, that the current broadcast message is a duplicate broadcast message, and discarding the current broadcast message;
• and
• determining, when the first valid broadcast message is not presented, that the current broadcast message is a newly-received valid broadcast message,
• wherein before performing the signature processing on the current broadcast data to determine the signature information corresponding to the current broadcast data, the operations further comprise:
• determining whether the current broadcast message meets a pre-filtering rule;
• and
• discarding the current broadcast message when the current broadcast message meets the pre-filtering rule.
