Abstract

The application discloses a communication method, a device and a storage medium, and belongs to the field of communication. The method is applied to a master access point of a communication system and comprises the steps of receiving a roaming start operation command, wherein the roaming start operation command is used for starting a roaming function of the access point included in the communication system, determining whether channel capacities of the access point in the communication system are consistent or whether optimal channels supported by a slave access point in the communication system are consistent or not based on the roaming start operation command, determining whether the master access point and the slave access point support different-channel roaming or not under the condition that the channel capacities of the access point in the communication system are inconsistent or the optimal channels supported by the slave access point in the communication system are inconsistent or not, and configuring the access point in the communication system to use the same channel and/or bandwidth under the condition that the master access point and the slave access point do not support the different-channel roaming.

Description

Communication method, device and storage medium 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 avoiding service interruption. The technical scheme is as follows: In a first aspect, the application provides a communication method applied to a master access point of a communication system, the method comprises the steps of receiving a roaming start operation command, determining whether channel capacities of access points in the communication system are consistent or whether optimal channels supported by slave access points in the communication system are consistent or not based on the roaming start operation command, determining whether the master access point and the slave access point support different channel roaming or not in the case that the channel capacities of the access points in the communication system are inconsistent or the optimal channels supported by the slave access points in the communication system are inconsistent, and configuring the access points in the communication system to use the same channel and/or bandwidth in the case that the master access point and the slave access points do not support the different channel roaming. Wherein in case of inconsistent channel capabilities of access points in the communication system or inconsistent optimal channels supported by the slave access points in the communication system, if the master access point and the slave access point do not support abnormal channel roaming, the access points in the communication system are configured to use the same channel and/or bandwidth. Because the access points of the communication system use the same channel and/or bandwidth, when the station roams between different access points, the channel does not need to be switched, so that the roaming performance of the access points is improved, namely the roaming performance of the communication system is improved. In one possible implementation, the configuring the access points in the communication system to use the same channel and/or bandwidth includes transmitting information of a first channel to the slave access points of the communication system, the information of the first channel being used to configure the slave access points of the communication system to use the same channel and/or bandwidth. Thus, the same channel is configured from the access point in the communication system through the first channel information, so that the station does not need to switch channels when roaming between different access points, and the roaming performance of the access point, namely the communication system, is improved. In another possible implementation, the method further comprises configuring the channel and/or bandwidth of the master access point to be the same as the channel and/or bandwidth of a slave access point in the communication system, respectively, based on the information of the first channel. In this way, the access points (the master access point and the slave access point) in the communication system are configured with the same channel through the first channel information, so that when the station roams between different access points, the channel does not need to be switched, and the roaming performance of the access points is improved, namely the roaming performance of the communication system is improved. In another possible implementation, the method further comprises configuring a channel and/or bandwidth of the secondary access point in case the primary access point and the secondary access point support abnormal channel roaming, the channel of the secondary access point being an optimal channel of the secondary access point. Thus, the communication performance can be improved by using the own optimal channel from the access point. In another possible implementation, the method further includes configuring a channel and/or bandwidth of the master access point, where the master access point and the slave a
