Problems solved by technology

However, the APs in the current AP recommendation list are usually only determined based on the signal strength of the surrounding APs detected by the currently associated AP of the mobile device, and the signal strength of the AP is easily interfered by various factors, so the reliability of the predicted AP lower

Embodiment Construction

[0069] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0070]For the convenience of readers' understanding, the terms involved in the embodiments of the present application are explained below.

[0071] Roaming: The action that a mobile device switches from being associated with one AP to another, also known as handover.

[0072] Association: A state in which a mobile device establishes a communication connection (also called link or connection) with an AP. The mobile device is associated with a certain AP, that is, the mobile device visits the certain AP, or the certain AP provides communication services for the mobile device.

[0073] Mobile equipment: mobile terminal equipment, also called mobile terminal. In a wireless local area network (Wireless Local Area Network, WLAN), a m...

Abstract

The invention discloses an AP prediction method, device and system, and belongs to the field of communication. The method comprises: acquiring first historical roaming path information of a first mobile device, the first historical roaming path information comprising identifiers of sequentially arranged APs for reflecting a first historical roaming path of the first mobile device in a communication network, the first AP being the last AP passed by the first historical roaming path; and determining an AP prediction set based on the first historical roaming path information, the AP prediction set comprising an identifier of a roaming AP to which the first mobile device is predicted to be switched from the first AP. According to the invention, the problem of low reliability of the predicted AP is solved. The method, the device and the system are used for predicting the roaming AP.

Description

technical field [0001] The present application relates to the communication field, and in particular to an AP prediction method, device and system. Background technique [0002] A communication network usually includes multiple access points (access points, APs), and the APs are used to provide communication services for mobile devices. When the signal quality of an AP is lower than a specified signal quality threshold, it usually needs to switch the associated AP, that is, perform roaming. [0003] Currently, when a mobile device needs to roam, the AP associated with the mobile device can send an AP recommendation list to the mobile device. Multiple communication scans (also called network selection scans) to discover APs that the mobile device can associate with, and determine roaming APs among the discovered APs, thereby associating to the roaming APs. However, the APs in the current AP recommendation list are usually only determined based on the signal strength of the ...
