Problems solved by technology

[0004] When this wireless communication system is used in the M2M (Machine-to-Machine, machine-to-machine) field, its reliability cannot meet the needs
For example, in a smart meter reading system, all electric meters (i.e., terminals) are uniformly deployed and paid for uniformly. When using the current wireless communication system, if one of the electric meters cannot communicate with the main station (i.e., the host) due to arrears, Even if the other meters are not in arrears, the arrears meter cannot communicate with the master station
Therefore, the failure rate of the entire smart meter reading system is equal to the failure rate of a single meter, and the overall failure rate of the system is very high and the stability is poor

Embodiment 1

[0026] This embodiment provides a data packet transmission method, such as figure 1 shown, including:

[0027] S101, judging whether the target address in the received data packet is the same as the local machine address.

[0028] The sender will carry the data packet in the IP message to the receiver. The header of the IP message includes the address of the sender, the address of the receiver, etc., and the data packet is located in the body of the IP message . For the case where the sender / receiver is the network side host, the corresponding sender / receiver address can be the IP address of the network side host; for the case where the sender / receiver is the device side terminal, the corresponding sender / receiver The address may be an MSISDN (Mobile Station Integrated Services Digital Number, mobile station integrated services digital code, commonly known as a phone number) of the terminal.

[0029] Each data packet includes attribute fields such as destination address, so...

Embodiment 2

[0035] The scenario of this embodiment is: terminal A has a data packet that needs to be sent to a host in the wireless network, but cannot establish a bearer link with the host. For example, the smart meter needs to report the electricity consumption data to the main station of the electric power company, but the SIM card of the smart meter is in arrears and cannot access the Internet.

[0036] see figure 2 , in this embodiment, in addition to establishing a bearer link with the host in the wireless communication network, the terminal can also establish a bearer link between terminals to realize local interconnection on the device side. Such as image 3 As shown, the data packet transmission method of the present embodiment includes the following steps:

[0037] S201. Terminal A and terminal B establish a bearer link that satisfies the quality of service in the data packet, and forward the data packet to terminal B through the bearer link.

[0038] The reason why terminal...

Embodiment 3

[0069] The scenario of this embodiment is: the host in the network needs to send a data packet to the terminal A on the device side, but the host cannot establish a bearer link with the terminal. For example, when the main station of the power company needs to perform remote meter reading on a smart meter, it finds that it cannot establish a connection with the smart meter.

[0070] After the host fails to establish a bearer link that satisfies the quality of service in the data packet with terminal A, if Figure 6 As shown, the data packet transmission method of the present embodiment includes the following steps:

[0071] S301. The host searches for terminal B located on the same subnet as terminal A, and establishes with terminal B a bearer link that satisfies the quality of service in the data packet; and sends the data packet to terminal B through the bearer link .

[0072] The host in the wireless network can find other terminals (such as terminal B) that are located i...

Abstract

The embodiment of the invention discloses a data packet transmission method and terminal equipment. The method comprises the following steps of: judging whether a target address in a received data packet is the same as a local address; and if the addresses are not the same, establishing a bearing link meeting quality of service in the data packet with the equipment of the target address, and forwarding the data packet to the equipment of the target address through the bearing link. Under the condition that the bearing link cannot be established between a terminal and a network side host, the data packet is forwarded by using other equipment as a trunk node so as to realize indirect communication between the terminal and the network side host, improve the stability of a wireless communication system and reduce the integral fault rate of the system.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data packet transmission method and terminal equipment. Background technique [0002] An existing wireless communication system consists of a host on the network side and multiple terminals. A dedicated wireless bearer link (usually through a 2G / 3G network) needs to be established between the host and each terminal to communicate. If the terminal cannot establish a bearer link with the host, it cannot communicate with the host. [0003] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: [0004] When such a wireless communication system is used in the M2M (Machine-to-Machine, machine-to-machine) field, its reliability cannot meet requirements. For example, in a smart meter reading system, all electric meters (i.e., terminals) are uniformly deployed and paid for uniformly. When using the c...
