detailed description

In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Figure 1 exemplarily shows a schematic diagram of the architecture of a dedicated wireless network communication system applicable to the embodiment of the present invention. As shown in Figure 1, the dedicated wireless network communication system includes a dedicated wireless network 110, a protocol conversion device 120, and a public switched telephone network 130 , terminal 111, terminal 112, terminal 113, terminal 131, terminal 132 and terminal 133; wherein, on the one hand, the protocol conversion device 120 is connected to the dedicated wireless network 110, and the dedicated wireless network 110 is respectively connected to the terminal 111, the terminal 112 and the terminal 113; On the one hand, the protocol conversion device 120 is connected to the public switched telephone network 130, and the public switched telephone network 130 is respectively connected to the terminal 131, the terminal 132 and the terminal 133; optionally, the connection mode can be a wired connection or a wireless connection.

In the embodiment of the present invention, the dedicated wireless network 110 is a dedicated wireless network that does not have operator qualification capabilities; the protocol stacks of the dedicated wireless network 110 and the public switched telephone network 130 are different, so the dedicated wireless network 110 and the public switched telephone network 130 The encoding protocols are different. When communicating between the two networks, the protocol converting device 120 needs to convert the encoding protocol of the data packets.

When the dedicated wireless network communication system communicates, it can be divided into the following two situations:

The first type, the internal communication of the private wireless network 110 or the internal communication of the public switched telephone network 130: first, the internal communication of the private wireless network 110, for example, the terminal 111, the terminal 112 and the terminal 113 connected by the private wireless network 110, and the terminal 111 When sending a data packet to the terminal 112, the data packet is sent from the terminal 111 to the dedicated wireless network 110, and then sent from the dedicated wireless network 110 to the terminal 112. During this process, the data packet does not need to undergo protocol conversion, and all use the dedicated wireless network 110 Supported encoding protocols are encoded; second, public switched telephone network 130 internal communication, for example, public switched telephone network 130 connects terminal 131, terminal 132 and terminal 133 respectively, when terminal 131 sends a data packet to terminal 132, the data The packet is sent from the terminal 131 to the public switched telephone network 130, and then sent to the terminal 132 by the public switched telephone network 130. During this process, the data packet does not need to be converted into a protocol, and the encoding protocol supported by the public switched telephone network 130 is used for encoding;

The second type is the communication between the private wireless network 110 and the public switched telephone network 130: for example, the terminal 111 connected to the private wireless network 110 sends a data packet to the terminal 132 connected to the public switched telephone network 130, and the data packet is sent from the terminal The sending process from 111 to terminal 132 is as follows: terminal 111 sends to dedicated wireless network 110 a data packet encoded using the encoding protocol supported by dedicated wireless network 110, and dedicated wireless network 110 sends the encoding protocol encoded by dedicated wireless network 110 to protocol conversion device 120. data packet, the protocol conversion device 120 converts the data packet encoded by the encoding protocol supported by the private wireless network 110 into: a data packet encoded by the encoding protocol supported by the public switched telephone network 130, and then the protocol conversion device 120 uses the public switched telephone The data packet encoded by the encoding protocol supported by the network 130 is sent to the PSTN 130 , and the PSTN 130 sends the data packet encoded by the encoding protocol supported by the PSTN 130 to the terminal 132 .

Step S203: converting the data packet encoded using the encoding protocol supported by the first network into a data packet encoded using the encoding protocol supported by the second network;

Step S204: Send the data packet encoded using the encoding protocol supported by the second network to the second network.

In the above step S202, if the first network is a private wireless network, then the second network is a public switched telephone network: the encoding protocol of each first network corresponds to an encoding protocol of a second network; the encoding protocol of each second network corresponds to At least one coding protocol of the first network; or, if the first network is a public switched telephone network, the second network is a dedicated wireless network: each coding protocol of the second network corresponds to a coding protocol of the first network; An encoding protocol of a network corresponds to an encoding protocol of at least one second network.
