Problems solved by technology

However, with the prior art, when the communication between the first device and the second device is required, if network switching is required, the first device and the second device need to switch to the second network respectively. If the second network switched to by the first device and the second device are different, the first device and the second device will not be able to communicate in the switched network, resulting in network switching failure

Embodiment 1

[0084] see figure 1 , which is a flow chart of a method for network switching provided in this embodiment, the method is executed by the first device, and specifically includes the following steps:

[0085] 101: The first communication module of the first device sends network switching request information to the first communication module of the second device, where the network switching request information includes the second communication type identifier and the MAC address of the second communication module of the first device.

[0086] 102: When receiving the response of accepting the network switching request returned by the first communication module of the second device, the second communication module on the first device corresponding to the second communication type identifier searches for currently joinable candidate networks.

[0087] 103: When a candidate network that can be joined is found, the second communication module on the first device corresponding to the s...

Embodiment 2

[0111] see Figure 5 , is a flow chart of a method for network handover provided in this embodiment. The method specifically includes the following steps:

[0112] 501: The first communication module of the first device sends network switching request information to the first communication module of the second device.

[0113] Wherein, the network switching request information includes at least the second communication type identifier and the MAC address of the second communication module of the first device;

[0114] It should be noted that the second communication type identifier includes at least one of the communication module type identifier used to indicate the communication module used after network switching or the network type identifier used to indicate the second network to be switched to.

[0115] For example, the first communication module of the first device and the first communication module of the second device are communicating through the first communicatio...

Embodiment 3

[0165] see Figure 6 , is a flow chart of a method for network handover provided in this embodiment. The method specifically includes the following steps:

[0166] 601: The first communication module of the first device sends network switching request information to the first communication module of the second device.

[0167] Wherein, the network switching request information includes at least the second communication type identifier and the MAC address of the second communication module of the first device;

[0168] It should be noted that the second communication type identifier includes at least one of the communication module type identifier used to indicate the communication module used after network switching or the network type identifier used to indicate the second network to be switched to.

[0169] For example, the first communication module of the first device and the first communication module of the second device are communicating through the first communicatio...

Abstract

The invention discloses a method, a device and a system for switching a network and belongs to the field of communication. The method comprises the following steps of: sending network switching request information to a first communication module of second equipment from a first communication module of first equipment; when receiving a response for receiving a network switching request, which is returned by a first communication module of the second equipment, searching an addable candidate network by a second communication module of the first equipment; when searching the addable candidate network, determining a second network corresponding to a second communication type mark from the candidate network by the second communication module on the first equipment, which corresponds to the second communication type mark, and adding the second network; and sending a network mark of the second network to the first communication module of the second equipment through the first communication module of the first equipment, so as to add the second communication module corresponding to the second communication type mark on the second equipment into the second network. According to the invention, the first equipment and the second equipment can successfully switch a communication network and carry out communication through the switched second network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for network switching. Background technique [0002] With the evolution of home network technology, there are more and more types and data formats of current home digital devices, and users have more and more demands for multimedia content such as high-definition TVs and Internet videos, as well as data sharing between user devices. In general households, a single home network technology cannot achieve 100% coverage. For example, for a PLC (Power Line Communication, power line communication) network, although there are power sockets in each room, the interference of the PLC channel is relatively large, which may affect the performance of the PLC; for WiFi (Wireless Fidelity, wireless fidelity technology ), it may be due to the attenuation of the signal caused by the structure of the house and the density of building materials, which reduces the cover...
