Embodiment 1

[0042] see figure 1 , is a flow chart of a method for solving co-channel interference provided by Embodiment 1 of the present invention. The method in the embodiment of the present invention can be executed by a processing device for solving co-channel interference implemented by hardware and / or software, and the implementing device is typically configured in a terminal device together with the first communication module and the second communication module.

[0043] The method includes:

[0044] 110. During the process of transmitting the first packet between the first communication module in the terminal device and the connected first external device, it is detected that the second communication module in the terminal device and the connected second external device start When transmitting the second packet, suspend the transmission of the first packet.

[0045] 120. After detecting that the transmission of the second packet is completed, resume the transmission of the first...

example

[0061] Take the terminal device as the intelligent gateway device (refer to figure 2 ) as an example to describe the method of this embodiment.

[0062] In this example, the first message packet carries the monitoring information transmitted by the first external device to the first communication module, or carries the monitoring information transmitted by the first communication module to the first external device. Control instruction;

[0063] The second packet carries monitoring information transmitted by the second external device to the second communication module, or carries a control command transmitted by the second communication module to the second external device.

[0064] The smart gateway device is introduced below.

[0065] see figure 2 , the smart gateway device is typically configured in an area where multiple smart devices that need to be monitored uniformly belong. For example, a family contains multiple smart devices that need to be monitored uniformly...

Embodiment 2

[0097] see Figure 4 , is a schematic structural diagram of an apparatus for solving co-channel interference provided by Embodiment 2 of the present invention. The device includes: a packet transmission suspension module 210 and a packet transmission recovery module 220 .

[0098] Wherein, the message packet transmission suspending module 210 is used to monitor the second communication module in the terminal device during the process of transmitting the first message packet between the first communication module in the terminal device and the connected first external device When the connected second external device starts to transmit the second packet, the transmission of the first packet is suspended; the packet transmission recovery module 220 is used to detect that the transmission of the second packet is completed , resume the transmission of the first packet.

[0099] In the above solution, the message packet transmission suspension module 210 can be specifically used t...

Abstract

The invention provides a method and a device for resolving co-frequency interference, which belong to the technical field of information. The method comprises the following steps. In the process of transmitting a first packet from a first communication module in a terminal device to a first external terminal device in connection with the first communication module, when a second communication module in the terminal device is monitored to start to transmit a second packet to a second external device in connection with the second communication module, the transmission of the first packet is then halted. When the second packet transmission is completed, the transmission of the first packet is resumed. In the invention, a higher transmission priority is given to the second packet with a smaller amount of data so that the transmission of the first packet with a larger amount of data can be resumed only after the transmission of the second packet is completed. This does not cause packet loss for the co-frequency interference resulting from the same communication band of the first communication module and the second communication module, so that the first terminal device can communicate effectively with the second external communication device.

Description

technical field [0001] Embodiments of the present invention relate to the field of information technology, and in particular, to a method and device for solving co-channel interference. Background technique [0002] In the prior art, a terminal device communicates with a plurality of external devices supporting different communication protocols. Generally, at least two communication modules are installed in the terminal device, each supporting a different communication protocol. In this way, each communication module can It is convenient to connect external devices consistent with its own communication protocol for communication, so as to realize the communication between one terminal device and multiple external devices supporting different communication protocols. A typical application scenario is, for example, a smart gateway device for unified monitoring of multiple smart devices supporting different communication protocols in a set area. [0003] Since the adopted comm...
