The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

The link processing method, apparatus, electronic device and storage medium provided in the following embodiments of the present application may be applied to a network topology structure of a multi-link in a communication system such as a 3G, 4G or WPAN that employs a TDD technology. The network topology structure comprises a first device and two or more second devices, wherein the first device and the second devices are in communication connection through independent links, data can be exchanged among the devices, and the first device and the second devices can also be connected with network devices such as high-level network devices or network devices in the Internet. At least one second device may be connected to the first device. In a WPAN, the first device is, for example, a cell phone, a tablet computer, or the like. The second device may be, for example, a wireless headset, a smart wristwatch, or other data sensor. In a WPAN, a first device and each second device may be in communication connection via an independent link, and the first device and each second device may transmit via any type of WIreless transmission technology, such as WIreless-Fidelity (WiFi), Infrared Data Association (IrDA), Bluetooth Low Energy (BLE), and Zigbee (Zigbee).

In a multi-connection application scenario, scheduling conflicts may occur between links of a device maintaining multi-connection, which may result in reduced stability of the links; according to actual application requirements, the data pressure of each link may be different, and the device needs to make the link with higher transmission pressure have more bandwidth according to the data pressure of different links, so as to improve the bandwidth utilization rate and the overall performance of application.

According to the link processing method provided by the embodiment of the application, through the multi-connection anchor point arrangement optimization technology, after a plurality of connections are established, the anchor points of each link can be reasonably arranged according to each network requirement of each link, so that the bandwidth duty ratio of each link is planned, meanwhile, the scheduling conflict among the links is avoided, and finally, better network service and user experience can be provided for a user or a system.

Fig. 1 is a schematic diagram of an application scenario of the present application, and as shown in fig. 1, in a network including a first device and two or more second devices, links of the first device and the second devices may be uniformly or proportionally arranged in an Interval (Interval) to reduce scheduling conflicts, so that links requiring more bandwidth have more communication bandwidth, and overall performance of the network is improved. For example, the bandwidth duty cycle of each link is planned so that the second device a occupies 10% of the bandwidth, the second device B occupies 20% of the bandwidth, the second device C occupies 40% of the bandwidth, and the second device D occupies 30% of the bandwidth, thereby avoiding scheduling conflicts between links and improving the stability of the links.

Fig. 2 is a schematic diagram of another application scenario of the present application, and as shown in fig. 2, a first device may configure response delays of respective connected second devices according to a device response speed requirement. For example, the response delay of each link is planned so that the second device a is 4xT response delay, the second device B is 1xT response delay, the second device C is 2xT response delay, and the second device D is 3xT response delay, thereby avoiding scheduling collision between links and improving the stability of the link.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 3 is a flowchart of a link processing method provided in an embodiment of the present application, and as shown in fig. 3, the method in the embodiment may be applied to a network including a first device and two or more second devices, where the first device and the second devices are communicatively connected through independent links, and the method in the embodiment may include:

s101, the first equipment sends a connection parameter updating request to at least one second equipment.

In this embodiment, the first device may implement, based on a BLE 5.0-series standard protocol, a connection layer direction in which the first device performs collision-free arrangement on each link anchor point uniformly or proportionally by using a specific parameter configuration, a specific flow process, and a first device parameter application. For example, the CONNECTION layer of the first device may send a CONNECTION parameter update request (LL _ CONNECTION _ PARAM _ REQ PDU) to the second device.

It should be noted that the present embodiment does not limit the types of the first device and the second device in the topology. In the topology structure, the first device may be a master device and the second device may be a slave device, the first device may be a slave device and the second device may be a master device, the first device may be a multi-role device, and the second device may be a master device or a slave device.

And S102, when the second equipment confirms the connection parameter updating request, determining the moving position of the link anchor point according to the instantaneous reference point and the window moving distance.

In this embodiment, before determining the moving position of the link anchor point according to the instantaneous reference point and the window moving distance, the method further includes: and negotiating with the second device to determine the instantaneous reference point through a connection event of the link. For example, the first device and the second device perform negotiation according to the CE parameters to determine the Instant reference point Instant.

Optionally, the sum of the lengths of the connection events on all links is not greater than the minimum connection interval in each link.

Specifically, The Length Of a Connection Event represents The occupation space Of The Connection Event within one Connection Interval (Connection Interval), because all Of which is called The Length Of Connection Event, abbreviated CE _ LEN. The method directly determines the CE _ LEN of the first device by using a BLE5.1 standard protocol, wherein a BLE5.1 specification Vol2.PartE7.8.18LE Connection Update section can be configured as a CE _ LEN, and two parameters, namely Minimum _ CE _ Length and Maximum _ CE _ Length, existing when Connection parameter Update is initiated are configured as the CE _ LEN, so that the CE _ LEN parameter provided by the method is determined. The first device, as a link manager, may configure different CE _ LENs and multiple intervals (intervals) for each link according to bandwidth requirements and response speed requirements of each link, so that links with greater bandwidth requirements occupy more bandwidth, and devices with higher response speed requirements have smaller intervals. Assuming that the first device as a master device sequentially establishes Connection events A, B, C, D with a plurality of surrounding slave devices, the first device multiplies the Connection relationship Connection Interval of each link, where the smallest Connection Interval is denoted as Intv _ Min, the intervals of other events B, C, D are multiplied with Intv _ Min, and the first device offsets several events from a reference point (denoted as Offset). Fig. 4 is a schematic diagram of a connection interval of multiple links according to an embodiment of the present application, and as shown in fig. 4, in a process of arranging links, an algorithm sets a timing relationship of each link as follows:

step 1) write Event _ a _ Offset equal to 0

Step 2) causes Event _ B _ Offset to be Event _ a _ Offset + CE _ LEN _ a

Step 3) causes Event _ C _ Offset to be equal to Event _ B _ Offset + CE _ LEN _ B

Step 4) command Event _ D _ Offset to Event _ C _ Offset + CE _ LEN _ C

The above procedure may be implemented by the first device initiating a connection parameter update. Algorithm limiting conditions are as follows: the sum of CE _ LEN of multiple links cannot be greater than the minimum Interval, otherwise, the problems of insufficient bandwidth and link collision may occur, and the purpose of link arrangement optimization cannot be achieved.

Optionally, determining the mobile position of the link anchor point according to the instantaneous reference point and the window moving distance includes: and moving the link anchor point backward by a window moving distance by taking the instantaneous reference point as a starting point position.

Specifically, fig. 5 is a schematic diagram of a multilink mobility anchor point according to an embodiment of the present application, and as shown in fig. 5, a first device and a second device calculate a reasonable window mobility distance WinOffset through a negotiated Instant reference point Instant. Then the first equipment and the second equipment move backwards by a WinOffset distance at the same Instant position according to the convention; where OldInterval indicates the old connection interval and New Interval indicates the New connection interval. The embodiment can realize the movement of the connection event anchor point, and the subsequent scheduling is scheduled periodically according to the new Interval.

S103, adjusting the connection parameters of the link according to the mobile position of the link anchor point.

In this embodiment, adjusting the connection parameters of the link according to the mobile location of the link anchor point includes: starting from the mobile position of the link anchor point, the connection interval of the link and/or the bandwidth duty cycle of the connection event are adjusted.

Optionally, adjusting the connection interval of the link includes: adjusting the connection interval of each link according to the response speed requirement of each link; wherein, the connection intervals of the links are equal or in a multiple relation.

Specifically, the uniform arrangement shown in fig. 6 may be implemented by configuring the connection Interval CE of the first link to be Interval/2 and configuring the connection Interval CE of the second link to be Interval/2 through connection parameter update. In this case, link 1 occupies 1/2 bandwidth and link 2 occupies 1/2 bandwidth. The multiple relation arrangement shown in fig. 7 may also be implemented by configuring, through connection parameter update, a connection Interval of the first link, a connection event bandwidth duty cycle CE, a connection Interval of the second link, and a connection event bandwidth duty cycle CE, where the connection Interval is CI/2. In this case, link 1 will have a faster response speed and can alternatively occupy the full bandwidth.

Optionally, adjusting the bandwidth duty cycle of the connection event of the link includes: according to the bandwidth requirement of each link, adjusting the bandwidth duty ratio of the connection event of each link; wherein, the lengths of the connection events of the links are equal or in a multiple relation.

Specifically, the connection Interval of the first link may be configured by updating the connection parameter, the bandwidth duty cycle CE of the connection event is 3 × CI/4, the connection Interval of the second link is CI, and the bandwidth duty cycle CE of the connection event is 1 × CI/4, so as to implement the proportional relationship arrangement shown in fig. 8. In this case, link 1 occupies 3/4 bandwidth and link 2 occupies 1/4 bandwidth. The multiple relation arrangement shown in fig. 9 may also be implemented by configuring, through connection parameter update, a connection Interval of the first link, a bandwidth duty cycle CE of a connection event, a connection Interval of the second link, a bandwidth duty cycle CE of a connection event, a connection Interval of the third link, and a bandwidth duty cycle CE of a connection event, where each connection Interval is CI/2, and each connection Interval of the first link is CI/4. In this case, link 1 and link 3 will have faster response speed, and link 1 can occupy the bandwidth range of 1/2 to 3/4 times Interval, and link 3 always occupies 1/4 of Interval.

In this embodiment, a connection parameter update request is sent to at least one second device through a first device; when the second equipment confirms the update request of the connection parameters, determining the mobile position of the link anchor point according to the instantaneous reference point and the window moving distance; and adjusting the connection parameters of the link according to the mobile position of the link anchor point. Therefore, reasonable arrangement of the multi-link scheduling is realized, scheduling conflict among the links is avoided, the stability of the links is improved, the bandwidth duty ratio of each link is optimized, and the utilization rate of bandwidth resources is improved.

S203, determining the window moving distance according to the minimum length of the connection event and the maximum length of the connection event in the connection parameter updating request.
