Embodiment Construction
[0029] figure 1 The flow chart of the method that realizes gateway selection for the present invention, as figure 1 shown, including:
[0030] Step 100, when a machine-to-machine (M2M) terminal needs to perform data transmission, the M2M terminal broadcasts its remaining power information to all gateways in the network.
[0031] It should be noted that, the method for the M2M terminal to broadcast the remaining power information belongs to the communication method commonly used by those skilled in the art. For example, the M2M terminal carries and broadcasts the remaining power information on the shared broadcast channel.
[0032] Step 101 , when each gateway receives the remaining power information of the M2M terminal, it calculates the signal-to-noise ratio when receiving the remaining power information of the M2M terminal, and at the same time, sends the remaining power of the gateway to other gateways in the system except itself.
[0033] It should be noted that the met...

The invention discloses a gateway selecting method and system. The method comprises the steps that when a machine-to-machine (M2M) terminal needs to conduct data transmission, the M2M terminal broadcasts the residual electricity information of itself; each gateway calculates the signal to noise ratio generated when the residual electricity information of the M2M terminal is received and sends the residual electricity of itself to other gateways in the system at the same time; each gateway calculates the gateway matching index according to the signal to noise ratio generated when the residual electricity information of the M2M terminal is received by itself, the residual electricity of the M2M terminal, the residual electricity of itself and the residual electricity of other gateways; the M2M terminal receives the gateway matching indexes of the gateways and determines the gateway for data transmission of the M2M according to the matching indexes of the gateways. According to the method and system, the gateway matching index of each gateway is calculated according to parameters such as the residual electricity and signal to noise ratios, gateway selection is conducted according to the gateway matching indexes, the problems of unbalanced electricity consumption of the gateways is solved, and the service life of the system is longer.
Description
technical field [0001] The invention relates to the field of the Internet of Things, in particular to a method and system for realizing gateway selection. Background technique [0002] With the rapid development of the information society, the human-to-human (H2H) communication connection is far from meeting the needs of social development. The human-to-machine connection (Human-to-Machine, H2M) and machine-to-machine ( Machine to Machine (M2M for short) connection has gradually become a new growth point of communication connection, and it is also the main form of the Internet of Things. M2M technology is widely used in smart meter reading, health care, Internet of Vehicles, smart agriculture and other services, and has played an important role in promoting social progress. [0003] At present, when deploying M2M terminals, the use of gateway deployment has the following advantages; first, considering the cost of the service provider, if each M2M terminal is embedded with a...
