The embodiments of the present application will be described herein in conjunction with drawings.
S101, a first device sends a connection parameter updating request to at least one of the second devices.
In this embodiment, the first device can achieve, based on BLE5.0 series standard protocols and through specific parameter configuration, specific process handling, and parameter application of the first device, connection layers where a conflict-free arrangement evenly or proportionally carried out on anchor points of the respective links by the first device. For example, the connection layer of the first device may send a connection parameter updating request (LL CONNECTION PARAM REQ PDU) to the second device.
It should be noted that this embodiment does not limit types of the first device and the second device in the topological structure. In the topological structure, the first device may be a primary device, the second device may be a secondary device, or the first device may be a secondary device, the second device may be a primary device, or the first device may be a multi-role device and the second device may be a primary device or secondary device.
S102, determining a moving position of a link anchor point according to an instantaneous reference point and a window moving distance when the second device confirms the connection parameter updating request.
In this embodiment, before determining the moving position of the link anchor point according to the instantaneous reference point and the window moving distance, further including: negotiating with the second device through a connection event of the link to determine the instantaneous reference point. For example, the first device and the second device negotiate according to CE configuration parameters to determine the instantaneous reference point (Instant).
Optionally, a sum of lengths of connection events on all the links is not greater than a minimum connection interval among the links.
Specifically, the length of the connection event represents a space occupied by the connection event within a Connection Interval, which is abbreviated as CE_LEN because the full name is “The Length of Connection Event”. The present application directly uses the BLE5.1 Standard Protocol to determine the CE_LEN of the first device, here two parameters (Minimum_CE_Length and Maximum_CE_Length) that exist when a connection parameter update is initiated in the BLE5.1 Specification Vol2. Part E 7.8.18 LE Connection Update command section may be both configured as CE_LEN to determine the CE_LEN parameter proposed by the present application. The first device, as a link manager, may configure different CE_LENs and Intervals in a multiple-relationship for the respective links according to bandwidth requirements and response speed requirements of the respective links, to make a link with a greater bandwidth requirement occupy more bandwidth, and to make a device with a higher response speed requirement have a smaller Interval. Assuming that the first device is taken as a primary device to establish connection events A, B, C, and D with multiple surrounding secondary devices in turn, the first device will make the connection relationships of the respective links (Connection Interval) be in a multiple relationship. Here, marking the smallest Connection Interval as Intv_Min, the Intervals of other events B, C, D are multiple of Intv_Min, the first device will offset the events relative to an offset of a reference point (denoted as Offset).
Step 1) Let Event_A_Offset=0
Step 2) Let Event_B_Offset=Event_A_Offset+CE_LEN_A
Step 3) Let Event_C_Offset=Event_B_Offset+CE_LEN_B
Step 4) Let Event_D_Offset=Event_C_Offset+CE_LEN_C
The above-mentioned process may be implemented by the first device initiating a connection parameter update. Restriction conditions for the algorithm: a sum of CE_LENs of the multiple links cannot be greater than a minimum Interval, otherwise there will be insufficient bandwidth and link conflicts, which will not achieve optimization of link arrangement.

Optionally, the adjusting the connection interval of the link includes: adjusting connection intervals of the respective links according to response speed requirements of the respective links, where the connection intervals of the respective links are equal or in a multiple relationship.
Specifically, through the connection parameter update, a connection interval for a first link may be configured as CE=Interval/2 and a connection interval for a second link may be configured as CE=Interval/2, thus realizing a uniform arrangement shown in
Optionally, the adjusting the bandwidth duty cycle of the connection event of the link includes: adjusting bandwidth duty cycles of connection events of the respective links according to bandwidth requirements of the respective links, where lengths of the connection events of the respective links are equal or in a multiple relationship.
Specifically, through the connection parameter update, the connection interval may be configured as Interval=CI for the first link and the bandwidth duty cycle of the connection event for the first link may be configured as CE=3*CI/4, the connection interval for the second link may be configured as Interval=CI and the bandwidth duty cycle of the connection event for the second link may be configured as CE=1*CI/4, thus realizing a proportional relationship arrangement shown in

The storage medium may be any available medium that may be accessed by a generic-purpose or specific-purpose computer. An exemplary storage medium is coupled to a processor, so that the processor may read information from the storage medium and write information to the storage medium. Of course, the storage medium may also be an integral part of the processor. The processor and the storage medium may be located in an application-specific integrated circuit (ASIC). In addition, the application-specific integrated circuit may be located in the user equipment. Of course, the processor and the storage medium may also exist as discrete components in a communication device.
Those skilled in the art may understand that: all or part of the steps in the embodiments of the foregoing method may be implemented by a program instructing relevant hardware. The above-mentioned program may be stored in a computer-readable storage medium. When the program is executed, steps including the embodiments of the foregoing methods are executed; and the foregoing storage medium includes: a read-only memory (ROM), a random access memory (RAM), a magnetic disks or an optical disk, etc., which can store program codes.
Those skilled in the art will easily think of other embodiments of the present disclosure after considering the specification and practicing the present application disclosed herein. The present application is intended to cover any modification, use, or adaptive change of the present disclosure. These modifications, uses, or adaptive changes follow the general principles of the present disclosure and include common knowledge or commonly used technical means in the technical field that is not disclosed in the present disclosure. The description and embodiments are only regarded as exemplary, and the true scope and spirit of the present disclosure are pointed out by the following claims.
It should be understood that the present disclosure is not limited to the precise structure described above and shown in the figures, and various modifications and changes may be made without departing from its scope. The scope of the present disclosure is only limited by the appended claims.
