Abstract

The present application provides a method for selecting a gateway device. The method includes: a terminal device receives a message from the gateway device, the message includes identification information of the gateway device, and the identification information of the gateway device is used to indicate the gateway device's information. The terminal device confirms that the identification information of the gateway device is consistent with the identification information of the gateway device preset on the terminal device, and uses the gateway device as the selected gateway device, and the terminal device sends the data message to the to the selected gateway device described above. It is helpful for the terminal device to correctly identify the gateway device to which it is going.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a method, device and system for selecting a gateway. Background technique [0002] With the continuous enrichment of network services and terminal devices, different terminal devices and different types of gateways are connected to the same Layer 2 network, and different terminal devices need to use different gateway devices to connect to different service networks or different network provided by the operator. [0003] In particular, with the vigorous development of the Internet of Things (IoT) in recent years, the types of terminal devices (such as smart meters, smart water meters, etc.) are increasing, and there are more and more corresponding service networks of different types. For example, a smart meter in a residential area should be connected to the business network of the grid company through the grid gateway device, and the data on the meter shou...
