Abstract

The application discloses a communication method, a device and a storage medium, and belongs to the field of communication. The method comprises the steps of determining whether channel capacity of a first slave access point on a new line in a communication system is consistent with channel capacity of other access points in the communication system, determining whether a master access point and the first slave access point support different channel roaming under the condition that the channel capacity of the first slave access point is inconsistent with the channel capacity of other access points, and sending information of a first channel to the first slave access point under the condition that the master access point and the first slave access point support the different channel roaming, wherein the first channel is a channel which can be used by the first slave access point, and the information of the first channel is used for roaming configuration of the first slave access point.

Description

Communication method, device and storage medium The present application claims priority from chinese patent application No. 202411565062.7 entitled "communication method, apparatus and storage medium" filed on month 11 and 4 of 2024, the entire contents of which are incorporated herein by reference. Technical Field The present application relates to the field of communications, and in particular, to a communication method, apparatus, and storage medium. Background The wireless local area network may include a plurality of access points, and the coverage of the wireless local area network includes the coverage of the plurality of access points. The plurality of access points have roaming capabilities and are capable of providing roaming Services To Stations (STAs) within the coverage area of the wireless local area network. Within the coverage of the wireless local area network, the STA may move, possibly from the coverage of the first access point currently accessed to the coverage of the second access point, at which time the second access point may provide roaming services to the STA based on its own roaming capabilities through which the STA communicates with the STA. However, access points in wireless local area networks provide poor roaming performance. Disclosure of Invention The application provides a communication method, a device and a storage medium, which are used for improving roaming performance. The technical scheme is as follows: In a first aspect, the present application provides a communication method, applied to a master access point of a communication system, in the method, it is determined whether channel capabilities of a first slave access point newly on line in the communication system are consistent with channel capabilities of other access points in the communication system, if the channel capabilities of the first slave access point are inconsistent with the channel capabilities of the other access points, it is determined whether the master access point and the first slave access point support heterogeneous channel roaming, and if the master access point and the first slave access point support heterogeneous channel roaming, information of a first channel is sent to the first slave access point, the first channel is a channel that can be used by the first slave access point, and the information of the first channel is used for roaming configuration of the first slave access point. The method comprises the steps that a master access point determines that the channel capacity of a first slave access point which is newly on line in a communication system is consistent with the channel capacities of other access points in the communication system, then under the condition that the master access point and the first slave access point support abnormal channel roaming, the master access point obtains a first channel which can be used by the first slave access point and sends information of the first channel to the first slave access point, and the first slave access point performs roaming configuration based on the information of the first channel, so that the roaming performance of the first slave access point is improved, namely the roaming performance of the communication system is improved. In one possible implementation, the first channel is different from the second channel currently used by the master access point. In another possible implementation, the bandwidth of the first channel is different from the bandwidth of the second channel currently used by the primary access point. In another possible implementation, the method further includes transmitting information of a third channel to the first slave access point and the other access points, where the master access point and the first slave access point do not support abnormal channel roaming, the information of the third channel being used for the first slave access point and the other access points to configure the same channel and/or bandwidth. Wherein, since the first slave access point and other access points configure the same channel and/or bandwidth, the first slave access point performs roaming configuration based on the information of the first channel, thus improving the roaming performance of the first slave access point, namely improving the roaming performance of the communication system. In another possible implementation, the method further includes transmitting fourth channel information to the first slave access point in case the channel capability of the first slave access point is consistent with the channel capability of the other access points, the fourth channel being a channel usable by both the first slave access point and the other access points, the fourth channel information being used for roaming configuration by the first slave access point. So that the same channels can be configured. In another possible implementation, the method further includes receiving fifth channel information, transmittin
