Background

LE Audio is the next generation bluetooth Audio that operates based on bluetooth Low Energy (LE), while Classic Audio operates based on Classic bluetooth (also known as bluetooth BR/EDR).

The low power synchronous channel (LE Isochronous Channels) is one of the main functions introduced by the bluetooth core specification 5.2. It will help to implement Multi-Stream Audio (Multi-Stream Audio) and broadcast Audio for Audio Sharing (Audio Sharing) along with the related bluetooth Profiles (Profiles) currently under development. To support multi-Stream Audio, LE Audio introduced a Connected Isochronous Group (CIG) and a Connected Isochronous link (CIS). In the process of establishing the CIS connection, the request end device sends a connection request to the target device, receives an instruction returned by the target device, confirms the connection request, and naturally, the target device can also return a rejection instruction to reject the CIS connection request. The applicant finds that, when the CIS connection request is rejected, an error code (error code) is generally added in the rejection instruction, but the information provided by the error code is not enough for the requesting device to know the basis of rejection request made by the target device and the current existing CIS condition of the target device, so that the success rate of CIS establishment is reduced.

Accordingly, these steps and operations will be referred to herein, in several instances, as being performed by a computer, the computer performing operations including the processing of the computer by electronic signals representing data in a structured form. This operation transforms the data or maintains it at locations in the computer's memory system, which may be reconfigured or otherwise altered in a manner well known to those skilled in the art. The data maintains a data structure that is a physical location of the memory that has particular characteristics defined by the data format. However, while the principles of the application have been described in language specific to above, it is not intended to be limited to the specific form set forth herein, and it will be recognized by those of ordinary skill in the art that various of the steps and operations described below may be implemented in hardware.

The terms "first", "second", and "third", etc. in this application are used to distinguish between different objects and not to describe a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to only those steps or modules recited, but rather, some embodiments include additional steps or modules not recited, or inherent to such process, method, article, or apparatus.

Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for feeding back information of a connection isochronous link according to an embodiment of the present application. The method for feeding back link information during connection and isochronous communication provided by the embodiment of the application is applied to electronic equipment, and the specific process can be as follows:

step 101, a target device link layer controller receives a connection isochronous link request sent by a request end device, and reports the connection isochronous link request to a device processor.

After the LE Audio scheme is released, the success rate of CIS establishment directly affects the user experience for the connection-oriented LE Audio scheme. Supposing that a user plays music by using a mobile phone and an earphone which support LE Audio, if the user clicks a play key on the mobile phone, the mobile phone can immediately establish a CIS link with the earphone. In the process, one CIG and a plurality of CIS are required to be created, which can help low-power bluetooth establish a data link with high real-time requirement, and audio data can be transmitted on the data link. Fig. 2 is a schematic flow chart illustrating establishment of a connection isochronous Link according to an embodiment of the present application, where Host a is a processor of Host of Device a, i.e., device a, host B is a processor of Host of Device B, i.e., device B, LL a is a Link Layer of Device a, i.e., a Link Layer controller of Device a, and LL B is a Link Layer of Device B, i.e., a Link Layer controller of Device B.

As can be seen, during the establishment of the CIS. First, device a and device B establish a Bluetooth Low Energy (BLE) ACL connection. And finally, the Host A/LL A sends an LL _ CIS _ IND message to the Host B/LL B for confirmation to create a CIS link and start to send and receive CIS packets.

With continuing reference to fig. 3, fig. 3 is a flow chart illustrating the procedure of rejecting the connection isochronous link establishment request according to the embodiment of the present application. The CIS connection method comprises the steps that a Host A/LL A sends a CIS establishing request to a Host B/LL B through an LL _ CIS _ REQ message, the Host B/LL B REJECTs the request and returns an LL _ REJECT _ EXT _ IND message to REJECT the CIS connection request proposed by the Host A/LL A.

In the above steps, host B/LL B may REJECT the connection request of CIS through LL _ REJECT _ EXT _ IND and add an ErrorCode (error code) to LL _ REJECT _ EXT _ IND, but the information provided by the ErrorCode is not enough for Host a/LL a to know the basis of rejection request made by Host B/LL B and the current existing CIS condition of Host B/LL B. Therefore, it is desirable to provide a mechanism by which Host A/LL A can synchronize information about the CIS-based link with Host B/LL B.

In the embodiment of the present application, please refer to fig. 4, where fig. 4 is a message sequence chart in the connection isochronous link information feedback process provided in the embodiment of the present application. In this embodiment, the Host B/LL B in fig. 4 is taken as an execution main body for description, and the LL B receives a connection isochronous link request sent by a request end device (Host a/LL a), and reports the connection isochronous link request to the Host B. Specifically, host a (device a processor) may initiate an LE Get CIS Parameters message, i.e., an HCI command, to LL a (link layer controller of device a). After receiving the HCI command, LL a may initiate a request to LL B through a Link Layer command, i.e., an LL _ CIS _ GET _ REQ message. And after receiving the LL _ CIS _ GET _ REQ message, the LL B reports the request to the Host B.

Step 102, the device processor obtains parameter information of a currently established connection isochronous link event according to the connection isochronous link request.

In this embodiment, for example, before device B receives a connection isochronous link request sent by device a, it may already establish one or more connection isochronous links, and at this time, device B may obtain parameter information of a currently established connection isochronous link event. The parameter information of the connecting isochronous link event may include time offset information of the connecting isochronous link event, and in other embodiments, the parameter information may further include Sub-event (Sub) number information, sub-event Interval information (Sub _ Interval), ISO Interval information (ISO _ Interval), CIS _ Sync _ Delay, CIG _ Sync _ Delay, and the like.

It should be noted that the CIG exists when creating its first CIS, and all its constituent CIS should have the same Master. The Host assigns an identifier CIG _ ID to each CIG and assigns an identifier CIS _ ID to each CIS thereof, and different CIS must have different CIS _ IDs, which can be multiplexed if a CIS is terminated.

In one CIG, the time Interval ISO _ Interval (with a value range of 5ms-4 s) of each CIS event is the same, but each CIS anchor point may be different from the CIS Sync _ Delay of the CIG synchronization point. The CIS _ Sync _ Delay and the CIG _ Sync _ Delay are timing sequence parameters provided by the Master link layer to the Slave link layer and are used for realizing the synchronization of isochronous data streams by the upper application layer.

The same applies to the time Interval Sub _ Interval between multiple Sub (i.e. CIS Data PDU message transmission) within each CIS event. The CIS in the CIG may be arranged sequentially or staggered by appropriately setting the Sub _ Interval value and the spacing between different CIS anchor points.

And 103, the device processor creates an HCI reply instruction according to the parameter information and sends the HCI reply instruction to the link layer controller.

Continuing with fig. 4, in this embodiment, host B may return to LL B via LE CIS GET Response command of HCI after receiving LE _ CIS _ GET _ reqrest message transmitted by LL B.

In the embodiment of the application, the HCI layer provides an interface for uniformly accessing the HCI controller for the upper level, the interface is a series of instructions and events, and the interface is suitable for a BR/EDR controller, a BR/EDR/LE controller, an AMP controller and the like. The HCI is in the form of commands to access the controller. HCI link commands provide the ability to connect to other controllers. The BR/EDR controller contains commands like link management and link control for interacting with remote devices. The HCI command processing completion time is indeterminate, so when a command is processed, an event is returned for the command. There will be a handle in the transmission process for identifying the logical channel and controller between hosts, there are three types of handles: a connection handle, a logical link handle, and a physical link handle.

There are four types of data packets in the HCI, including: command (0 x 01), ACL (0 x 02), SCO (0 x 03), event (0 x 04), and ISO (0 x 05).

And step 104, the link layer controller feeds back to the request end equipment according to the HCI reply instruction.

In an embodiment, after receiving an HCI reply instruction, that is, an LE _ CIS _ GET _ reqrest packet, the link layer controller, that is, LL B may send the parameter information to device a through an LL _ CIS _ GET _ RSP packet, that is, feed back to a requesting device. The LL _ CIS _ GET _ RSP message is a Link Layer instruction, and the LL is a Link Layer, corresponds to a data Link Layer of the OSI model, and is a very important Layer in BLE.

At this time, the requesting device, that is, the device a, may clearly know the timing conditions of each CIS of the device B through the information returned by the LL _ CIS _ GET _ RSP message, based on the above information, the device a may consider the existing CIS conditions of the device B before establishing the CIS with the device B, and may try to avoid the time slot that may generate the conflict, thereby improving the success rate of establishing the CIS link.

As can be seen from the above, the method for feeding back connection isochronous link information provided in this embodiment of the present application may receive, by using a link layer controller, a connection isochronous link request sent by a requesting device, and report the connection isochronous link request to a device processor, the device processor obtains parameter information of a currently established connection isochronous link event according to the connection isochronous link request, the device processor creates an HCI reply instruction according to the parameter information and sends the HCI reply instruction to the link layer controller, and the link layer controller feeds back the HCI reply instruction to the requesting device. According to the method and the device, the parameter information of the CIS event established on the equipment can be fed back when the connection request of the CIS link is received, and therefore the success rate of establishment of the CIS link is improved.

The link isochronous link information feedback method of the present application will be further described below on the basis of the method described in the above embodiment. Referring to fig. 5, fig. 5 is another schematic flow chart of a connection isochronous link information feedback method according to an embodiment of the present application, where the connection isochronous link information feedback method includes:

in step 201, the link layer controller receives an isochronous link connection request sent by a requesting device, converts the isochronous link connection request into an HCI request command, and reports the HCI request command to the device processor.

In the embodiment of the present application, please continue to refer to fig. 4, the connect isochronous link request is a link layer command sent by the link layer controller LL a of the requesting device (device a). Specifically, host a (device a processor) may initiate an LE Get CIS Parameters message, i.e., an HCI command, to LL a (link layer controller of device a). After receiving the HCI command, LL a may initiate a request to LL B through a Link Layer command, i.e., an LL _ CIS _ GET _ REQ message. And after receiving the LL _ CIS _ GET _ REQ message, the LL B converts the request into an HCI request instruction and reports the HCI request instruction to the device processor, namely reporting the LE CIS GET Parameters message to the Host B.

In step 202, the device processor obtains the anchor time of the established connection isochronous link event according to the connection isochronous link request, and obtains the initial anchor time by controlling the access list.

In an embodiment, the processor Host B of the device B obtains the parameter information of the currently established connection isochronous link event, wherein the parameter information of the established connection isochronous link event may include the time offset information of the established connection isochronous link event. The time offset information may be calculated by the anchor time of the established connection isochronous link event and by controlling the access list to obtain the initial anchor time.

And step 203, calculating the time offset information of the established connection isochronous link event according to the initial anchor point time and the anchor point time of the established connection isochronous link event.

In an embodiment, please continue to refer to fig. 6, wherein fig. 6 is a schematic diagram illustrating a time offset information of a CIS event according to an embodiment of the present disclosure. In this embodiment, it can be seen that two CIS events have been established in the device B, and a time relationship between LL _ CIS _ GET _ REQ and the existing CIS time of the device B is as shown in the figure, and the device B may estimate a time offset between the current CIS time and the CIS time after itself by using an Access Control List (ACL) anchor point. As shown in fig. 6, the device B has two CIS times, and the device B can calculate the relevant time offset by the known ACL anchor point time and the CIS anchor point times of the following CIS event 1 and CIS event 2.

And step 204, calculating ISO interval information according to the anchor point time of the established connection isochronous link event, and acquiring sub-event quantity information and sub-event interval information of the established connection isochronous link event.

In an embodiment, the parameter information of the established connection isochronous link event may further include sub-event number information, sub-event interval information, ISO interval information, CIS _ Sync _ Delay, CIG _ Sync _ Delay, and the like. Wherein the ISO Interval information, i.e., ISO _ Interval, may be calculated from the anchor point time of the established connection isochronous link event with reference to fig. 6. In addition, for the CIS known by HostB, the related NSE (Number _ of _ Subevent, number of subevents) and Sub _ Interval (Subevent Interval) are also already known, as shown in fig. 6, and this CIS includes two subevents, NSE =2. The CIS _ Sync _ Delay and the CIG _ Sync _ Delay are timing sequence parameters provided by the Master link layer to the Slave link layer and are used for realizing the synchronization of isochronous data streams by the upper application layer.

The same applies to the time Interval Sub _ Interval between multiple subframes (i.e. CIS Data PDU message transmission) in each CIS event. The CIS in the CIG may be arranged sequentially or staggered by appropriately setting the Sub _ Interval value and the spacing between different CIS anchor points.

In step 205, the device processor creates an HCI reply instruction according to the parameter information and sends the HCI reply instruction to the link layer controller.

For example, continuing to refer to fig. 4, in this embodiment, host B may return to LL B via the LE CIS GET Response command of HCI after receiving the LE _ CIS _ GET _ Requrest message transmitted by LL B.

In step 206, the link layer controller converts the HCI reply instruction into a link layer reply instruction, and sends the link layer reply instruction to the link layer controller of the requesting device for feedback.

In an embodiment, after receiving an HCI reply instruction, that is, an LE _ CIS _ GET _ Requrest message, the link layer controller, that is, LL B may send the parameter information to the device a link layer controller, that is, LL a, through the LL _ CIS _ GET _ RSP message, and LL a then sends an LE GET CIS Parameters Complete message to Host a. The device A can clearly know the time sequence situation of each CIS of the device B through the information, and based on the information, the device A considers the existing CIS situation of the device B before establishing the CIS with the device B, and avoids time slots which possibly conflict with each other as far as possible, so that the success rate of establishing a CIS link is improved. For example, before the cell phone establishes a CIS with the headset, information such as time offset, ISO _ Interval, NSE, sub _ Interval, and the like of the existing CIS of the headset may be obtained through LL _ CIS _ GET _ REQ.

As can be seen from the above, the method for feeding back information of a connection isochronous link provided in this embodiment of the present application may include receiving, by a link layer controller, a connection isochronous link request sent by a request end device, converting the connection isochronous link request into an HCI request instruction, and reporting the HCI request instruction to a device processor, obtaining, by the device processor, an anchor point time of an established connection isochronous link event according to the connection isochronous link request, obtaining an initial anchor point time by controlling an access list, calculating time offset information of the established connection isochronous link event according to the initial anchor point time and the anchor point time of the established connection isochronous link event, calculating ISO interval information according to the anchor point time of the established connection isochronous link event, obtaining sub-event number information and sub-event interval information of the established connection isochronous link event, creating, by the device processor, an HCI reply instruction according to parameter information, and sending the HCI reply instruction to the link layer controller, where the link layer controller converts the HCI reply instruction into a link layer reply instruction, and sends the link layer reply instruction to the link layer controller of the request end device, so as to perform feedback. According to the method and the device, the parameter information of the CIS event established on the equipment can be fed back when the connection request of the CIS link is received, and therefore the success rate of establishment of the CIS link is improved.
