Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.

Fig. 1 is a schematic diagram of an architecture of a call prompt system according to an exemplary embodiment. As shown in fig. 1, the system may include a server 11, a network 12, a number of electronic devices such as access point devices 13, a cell phone 14, and the like.

The server 11 may be a physical server comprising an independent host, or the server 11 may be a virtual server carried by a cluster of hosts, or the server 11 may be a cloud server. In the operation process, the server 11 may operate a server-side program of a certain application to implement a related service function of the application, for example, when the server 11 operates a program of a mobile group office platform, the server may be implemented as a server of the mobile group office platform.

In this embodiment, the mobile group office platform not only can implement a communication function, but also can be used as an integrated functional platform with many other functions, for example, for processing internal events of a group such as an approval event (e.g., approval event such as leave request, office article claim, and finance), an attendance event, a task event, and a journal event, and for processing external events of a group such as ordering and purchasing, which is not limited in one or more embodiments of the present specification.

More specifically, the mobile corporate office platform may be supported by an Instant Messaging application in the related art, such as an Enterprise Instant Messaging (EIM) application, For example, Skype For

Microsoft

And the like. Certainly, the instant messaging function is only one of the communication functions supported by the mobile group office platform, and the mobile group office platform can also implement more other functions such as those described above, and details thereof are not described here.

The access point device 13, the handset 14 are only some types of electronic devices that may be used. Indeed, the present description may also support electronic devices of the type such as: tablet devices, notebook computers, Personal Digital Assistants (PDAs), wearable devices (e.g., smart glasses, smart watches, etc.), smart entrance guards, smart printers, smart attendance machines, etc., to which one or more embodiments of the present disclosure are not limited. During the operation process, the electronic device may operate a client-side program of an application to implement a related service function of the application, for example, when the electronic device operates a program of a mobile community office platform, the electronic device may be implemented as a client of the mobile community office platform.

It should be noted that: an application program of a client of the mobile community office platform can be pre-installed on the electronic equipment, so that the client can be started and run on the electronic equipment; of course, when an online "client" such as HTML5 technology is employed, the client can be obtained and run without installing a corresponding application on the electronic device.

And the network 12 for interaction between the access point device 13, the handset 14 and the server 11 may include various types of wired or wireless networks. In one embodiment, the Network 12 may include the Public Switched Telephone Network (PSTN) and the Internet.

Fig. 2 is a flow chart of a channel optimization method according to an exemplary embodiment. As shown in fig. 2, the method applied to an electronic device (such as the access point device 13, the mobile phone 14, etc. described above) may include the following steps:

step 202, dividing target WIFI channels to be detected into a plurality of groups.

In an embodiment, the target WIFI channels may be divided by a preset number, so that the number of channels in each group is not greater than the preset number.

In an embodiment, the target WIFI channel may include all channels supported by a communication module of the electronic device, for example, when the communication module is a WIFI module, the target WIFI channel may include a channel 1-channel 13 in a 2.4GHz band, a channel 149-165 in a 5GHz band, and the like, which is not limited in this specification.

And step 204, sequentially performing channel detection operations on the channels in each group, wherein a waiting interval with preset duration exists between the channel detection operations of adjacent groups.

In one embodiment, the target WIFI channel is divided into several groups, and the channel detection operations are sequentially performed on the channels in each group, so that the electronic device can perform normal processing operations in the waiting interval between the channel detection operations of adjacent groups. The normal processing operation may include other functions of the electronic device besides the channel detection operation, for example, when the electronic device is an access point device, the normal processing operation of the access point device may include a routing function, a data interaction function, and the like.

In an embodiment, when the processing performance of the electronic device is limited, at least a portion of the processing resources occupied by the channel detection operation and the normal processing operation overlap, so that by having a waiting interval between the channel detection operations of adjacent groups, the channel detection operation is prevented from being continuously performed for a long time, the interference of the channel detection operation on the normal processing operation of the electronic device can be reduced, and the user experience is prevented from being greatly influenced.

And step 206, performing channel optimization according to the channel detection result of the target WIFI channel.

In an embodiment, an optimal channel in the target WIFI channels may be determined according to channel detection results of all target WIFI channels, so that the optimal channel is configured as a communication channel, so as to improve a communication effect of the electronic device.

In an embodiment, in the process of sequentially performing channel detection operations on channels in each group, when any target WIFI channel is determined to be better than a current communication channel, the current communication channel may be updated to the any target WIFI channel, so that the electronic device may perform channel optimization as soon as possible and step by step until the current communication channel is updated to an optimal channel in the target WIFI channels.

For convenience of understanding, the technical solutions of one or more embodiments of the present specification are described by taking an enterprise instant messaging application "enterprise WeChat" as an example. Assuming that the access point device 13 runs an enterprise wechat client, the enterprise wechat client may utilize a processing resource provided by a processing chip configured in the access point device 13 to implement channel optimization for the access point device 13 in a software manner, and reduce the influence on the access point device 13 as much as possible.

Fig. 3 is a diagram illustrating group division of channels according to an exemplary embodiment. Assuming that a WIFI module is built in the access point 13, an enterprise wechat client running on the access point 13 may determine a channel that the WIFI module is allowed to use, that is, a target WIFI channel; for example, the target WIFI channels may include channel 1, channel 2, channel 3 … …, channel 13, etc. of the 2.4GHz band, and channel 149, channel 153, channel 157, channel 161, channel 165, etc. of the 5GHz band as shown in fig. 3.

The enterprise wechat client running on the access point device 13 may group the target WIFI channels. For example, when the preset maximum value of the group members of the enterprise wechat client 1 is 3, after the enterprise wechat client 1 performs group division on the target WIFI channels, each group may include at most 3 target WIFI channels, for example, as shown in fig. 3, the group division may include: group 1 consisting of channel 1, channel 2, and channel 3, group 2 consisting of channel 4, channel 5, and channel 6, group n consisting of channel 157, channel 161, and channel 165, and so on.

By running the enterprise wechat client on the access point device 13 and implementing the channel detection operation and the channel optimization by the enterprise wechat client in a software manner, an independent channel detection chip does not need to be added to the access point device 13, so that the internal structural complexity of the access point device 13 can be reduced, and the device cost can be reduced. Meanwhile, since the enterprise wechat client needs to occupy a certain processing resource during the operation process, and there may be a certain overlap between the processing resource and other processing functions of the access point device 13, in order to reduce the influence of the enterprise wechat client on other processing functions, the following processing operations may be implemented:

fig. 4 is a timing diagram illustrating a channel detection operation according to an exemplary embodiment. Assume that the enterprise wechat client running on the access point device 13 sequentially performs channel detection operations on target WIFI channels in group 1 to group n, where the channel detection time period corresponding to group 1 may include time periods T1 to T2 (i.e., a time period between time T1 and time T2) shown in fig. 4, that is, the enterprise wechat client performs channel detection operations on group 1 in the time periods T1 to T2.

After the channel detection operation for the group 1 is completed, the enterprise wechat client may suspend the channel detection operation for the remaining target WIFI channels, so that the access point device 13 may implement other processing functions within the time period T2-T3; then, the enterprise wechat client may perform a channel detection operation on group 2 during a channel detection period corresponding to group 2 (i.e., periods T3-T4).

Similarly, the enterprise wechat client may perform channel detection operations for each group in turn, and may avoid performing channel detection operations continuously for a long period of time, thereby reducing the impact on other processing functions in the access point device 13. In one case, the access point device 13 may perform other processing functions during the channel detection period; alternatively, the access point device 13 may suspend other processing functions for the channel sensing period.

After the enterprise wechat client performs the channel detection operation on the group n in the time period Tm-1 to Tm, it indicates that the enterprise wechat client has completed the channel detection operation on the n groups in sequence, which is equivalent to the end of a detection period, the enterprise wechat client may immediately enter a next detection period (for example, perform the channel detection operation on the group 1 in the time period Tm +1 to Tm + 2), or the enterprise wechat client may wait for a specific time or a specific trigger event and then enter the next detection period, which is not limited in this specification.

In an embodiment, after the enterprise wechat client completes the channel detection operation on all the n groups of target WIFI channels, the enterprise wechat client determines an optimal channel, and switches the access point device 13 from the current communication channel to the optimal channel (if the access point device 13 is already in the optimal channel, the channel does not need to be switched).

In an embodiment, the enterprise wechat client may switch the access point device 13 from the current communication channel to the better target WIFI channel whenever it finds a target WIFI channel that is better than the current communication channel used by the access point device 13, until it switches to the optimal channel. For example, assuming that the current communication channel where the access point device 13 is located is the channel 8, when the enterprise wechat client performs channel detection operation on the target WIFI channel of the group 1, it is found that the channel 2 is better than the channel 8, that is, the access point device 13 may be switched from the channel 8 to the channel 2, so that the current communication channel of the access point device 13 is updated to the channel 2; then, when the enterprise wechat client 1 continues to perform channel detection operation on the subsequent group, if the channel 157 is found to be better than the channel 2, the access point device 13 is switched from the channel 2 to the channel 157, so that the current communication channel of the access point device 13 is updated to the channel 157; if there is subsequently no more preferred channel than channel 157, access point device 13 will remain on channel 157, and that channel 157 is the best channel of all of the targeted WIFI channels.
