Roaming method in a multi-link scenario, multi-link device, and storage medium

The application relates to the field of wireless communication, and discloses a roaming method in a multi-link scenario, a multi-link device and a storage medium. The roaming method in the multi-link scenario includes: selecting a target network access device that meets a condition; disconnecting a logical entity on a secondary link of an original network access device from the original network access device; establishing a connection of the logical entity with the target network access device; determining a link through which the logical entity is connected with the target network access device as a primary link; and disconnecting a connection of the other logical entity other than the logical entity with the original network access device. The application realizes roaming of a terminal among different network access devices through link management and interactive control, ensuring service continuity and avoiding packet loss.

Apparatus and methods for extending and enhancing wireless networks. An exemplary wireless network configured according to the disclosure uses in-service Wireless Network Clients (WNCs), such as mobile phones, laptops, etc., to extend and enhance the wireless network coverage via peer-to-peer sub-networks. In one implementation, each WNC is configured to operate as a Service Access Node (SAN) to other wireless client devices in the same network. The SAN provides peer-to-peer communications capabilities (to communicate with wireless clients) and gateway functionality (to aggregate data traffic over its own uplink communications), thereby enabling wireless clients to piggyback their data link onto the WNC. Peer Control Manager (PCM) software on each WNC enables, disables, and controls the service functions for that WNC in accordance with an overarching Peer Controller (PC) entity operated by an Access Point Controller/Core Network.
