detailed description

In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the terms "system" and "network" are often used interchangeably herein. In this article, the term "and/or" is used to describe the association relationship of associated objects, for example, it means that there may be three relationships between the associated objects before and after. There are three cases of B alone. In this paper, the character "/" generally indicates that the contextual objects are "or" relationships.

The network architecture and business scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute limitations on the technical solutions provided by the embodiments of the present application. The evolution of the technology and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

The technical solution of the embodiment of the present application can be applied to a low-power audio processing system, and the audio broadcast signal is used as an example to illustrate the solution, but it should be understood that the solution of the present application is not limited to broadcast audio stream data communication, and can also be applied to the transmission of video , images, augmented reality (Augmented Reality, AR), virtual reality (Virtual Reality, VR) and other signal scenarios.

Audio Low Energy technology brings powerful Bluetooth capabilities to the wireless audio market, including: new higher-quality, more efficient audio codec capabilities, the ability to transmit multiple audio streams simultaneously, new Bluetooth audio broadcast capabilities and low power consumption Bluetooth's ability to transmit audio, etc.

In low-power audio technology, low-power broadcast audio involves profiles and services such as Basic Audio Profile (BAP) and Broadcast Audio Scan Service (BASS).

Wherein, the broadcast audio scanning service involves a related process of discovering broadcast sources in the broadcast audio processing system. The broadcast audio processing system includes broadcast receiving equipment (Broadcast Sink), broadcast assistant (Broadcast Assistant) equipment and broadcast source (Broadcast Source) equipment. Figure 1A and Figure 1B show two possible topologies for broadcast audio processing systems, respectively.

As shown in FIG. 1A, the broadcast source device and the broadcast assistant device may be configured on different devices. For example, the broadcast receiving device is a wireless Bluetooth earphone, which can use a portable terminal device such as a mobile phone as a broadcast assistant device to broadcast audio and audio streams with broadcast source devices such as TVs and computers.

As shown in FIG. 1B, the broadcast source device and the broadcast assistant device can be configured on the same device. For example, the broadcast receiving device is a wireless Bluetooth headset, and a portable terminal device such as a mobile phone can be used as a broadcast assistant device to broadcast audio streams synchronously with the portable terminal device, and the portable terminal device is also a broadcast source device.

In an embodiment of the present application, the broadcast source device and the broadcast assistant device can be configured on different devices. Generally speaking, the broadcast receiving device and the broadcast source device broadcast the audio data stream synchronously, and the operation of scanning and discovering the broadcast source needs to be performed. The device needs to consume a certain amount of power during the scanning process. The broadcast receiving device is generally an embedded device powered by a battery. Therefore, the broadcast receiving device will request the broadcast assistant device to perform an operation of scanning and discovering broadcast sources. Based on this, the broadcast receiving device can also be called a scan delegate (Scan Delegator).

The broadcast assistant device generally includes two parts: the Scanner Host and the Scanner Controller. When the broadcast assistant device performs a scanning operation, if it finds a broadcast source, it will add broadcast information through the broadcast audio scanning service (BASS). The Add Source Operation sends information about the broadcast source to the broadcast receiver.

Due to the provisions of the existing standard Basic Audio Profile (BAP) and privacy issues, the broadcast assistant device cannot directly use the identity address (Identity Address, IA) when performing the operation of adding a broadcast source, but uses a resolvable private address (Resolvable Private Address, RPA).

When there is only one broadcast source sending broadcast information, the scan controller will send the resolvable private address (RPA) used by the opposite end to the host device, and the broadcast assistant device will send this resolvable private address (RPA) to the broadcast receiver equipment. The broadcast receiving device uses a quicker way to synchronize with the broadcast source.

In one embodiment of the present application, the filter acceptance list method (Filter Accept List) based on the resolvable private address (RPA) can be used to improve the efficiency of discovering the broadcast source and save the power consumption of the scanning device.

During broadcasting, one broadcast source device can use a set of simultaneous streams to transmit broadcast information from a single broadcast source's stream to multiple broadcast receiver devices. Each stream is called a Broadcast Isochronous Stream (BIS). A group of BIS is called Broadcast Isochronous Group (BIG). For example, a TV streams broadcast audio data to multiple receivers, such as different individuals wearing earbuds. A broadcast source device may have multiple broadcast sources, so multiple broadcast synchronization groups (BIG) can be created.

The broadcast audio scanning service (BASS) stipulates that the broadcast source can be identified by triple information [address type (Advertiser_Address_Type), address (Advertiser_Address), advertising set ID (Advertising Set ID, SID)].

The Broadcast Synchronization Stream (BIS) may be identified by the broadcast identifier (Broadcast_ID) sent by the broadcast source device to the scanning device.

When the broadcast source device sends broadcast information of multiple broadcast sources, there will be a situation where the broadcast assistant device cannot obtain the specified broadcast source address, as shown in the flow chart in Figure 5, specifically including:

S51. The broadcast source device establishes a bonded relationship with the broadcast assistant device, and the broadcast source device enables a privacy mode (Controller-based privacy), so as to prevent addresses from being tracked.

S52. The broadcast source device sends broadcast information to the broadcast assistant device. The broadcast information comes from at least one broadcast source, and the at least one broadcast source includes a target broadcast source. In this schematic diagram, it is assumed that the broadcast source device sends broadcast information 1 and broadcast information 2 For the broadcast assistant device, the two broadcast information comes from two broadcast sources, and the two broadcast sources use the same identity resolving key (Identity Resolving Key, IRK) to generate two different RPAs (for example, use RPA_1 and RPA_2 respectively) to be carried on the Broadcast information 1 and Broadcast information 2.

S53, the broadcast assistant device completes the operation of scanning and discovering broadcast sources. Specifically, the scan controller obtains broadcast information through scanning, and the scan host can obtain the peer address by sending a low-power consumption read peer resolvable address command (LE Read Peer Resolvable Address command, as shown in Table 1) to the scan controller. The resolvable private address (RPA) used, because broadcast information 1 and broadcast information 2 come from different broadcast sources, when the scan controller receives the broadcast information sent by the two broadcast sources, it will send two different resolvable private addresses (RPA) is resolved into the same identity address (IA) and sent to the scanning host, that is to say, the LE Read Peer Resolvable Address command cannot obtain the address information of the two broadcast sources separately, so it will directly return a failure message.

Table 1 Low power consumption read peer resolvable address command

The low-power read peer resolvable address command is used to obtain the resolvable private address of the peer public random identity address currently being used. The peer identity address (IA) type occupies 1 byte (Octet), the peer identity address occupies 6 bytes (Octet), and the state occupies 1 byte (Octet), which can be parsed by the peer The size occupied by the address is 6 bytes (Octet).

S54, in the existing specification Basic Audio Profile (BAP), it is stipulated that the broadcast audio source device assigns a unique broadcast identifier for each broadcast synchronous flow information, namely the broadcast identifier (Broadcast_ID), and the broadcast assistant device executes adding When broadcasting a source, for security reasons, the address information of the broadcast source to be synchronized will not be carried. Generally, the broadcast source address will be set to 0 (or a sequence of all 0s), and the broadcast ID (Broadcast_ID) will be sent to the broadcast receiving device.

S55. The broadcast receiving device uses the broadcast identifier (Broadcast_ID) to perform a matching search, so as to implement synchronization of the broadcast audio data stream.

S56. The broadcast receiving device sends broadcast receiving state feedback information to the broadcast assistant device.

S57, when the broadcast receiving device stops synchronizing with the broadcast source device for some reason, when trying to re-synchronize, it needs to scan the broadcast information of all broadcast sources around, and judge whether the broadcast identification (Broadcast_ID) of the broadcast information matches in turn, and stop if it matches Scan to establish a resynchronization, otherwise continue with the scan operation.

When the broadcast receiving device stops synchronizing to the broadcast source and tries to synchronize again, it can only realize resynchronization after scanning all broadcast sources around it and judging the broadcast ID (Broadcast_ID) in turn. Moreover, the existing synchronization scheme makes the broadcast receiving device It takes a lot of time and power to resynchronize with the broadcast source.

It should be understood that the target broadcast source mentioned in this application refers to the broadcast source to be synchronized by the broadcast receiving device.

The solutions provided in the embodiments of the present application are mainly used to solve at least one of the above problems.

In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

S201. Receive broadcast information sent by a broadcast source device, where the broadcast information is sent by at least one broadcast source, and the at least one broadcast source includes a target broadcast source.

In an embodiment of the present application, the broadcast information may include a broadcast identifier (Broadcast_ID), a broadcast set identifier (SID), a resolvable private address (RPA), and the like. Exemplarily, when there are two broadcast sources, they are recorded as broadcast source 1 and broadcast source 2 respectively, the broadcast information of broadcast source 1 can be expressed as [Broadcast 1, RPA_1, SID1, Broadcast_ID_1], and the broadcast information of broadcast source 2 can be Expressed as [Broadcast 2, RPA_2, SID2, Broadcast_ID_2].

The above example is only an exemplary expression, and does not mean that broadcast information of a limited broadcast source can only be expressed in the above form. The broadcast information of the broadcast source may contain at least one of the above parameters, and the order of the above parameters may be changed arbitrarily.

In one embodiment of the present application, broadcast source 1 is used as an example in the present application, and optionally, broadcast source 2 may also be used as the target broadcast source. When there are more than two broadcast sources, it can also be assumed that broadcast source 3 [Broadcast 3, RPA_3, SID3, Broadcast_ID_3] is the target broadcast source, etc.

In an embodiment of the present application, the target broadcast source may be a broadcast source that the broadcast receiving device has synchronized before and tries to synchronize again, or may be a broadcast source that the broadcast receiving device performs synchronization for the first time.

In an embodiment of the present application, the address information of the target broadcast source may include a resolvable private address (RPA), a broadcast identifier (Broadcast_ID), and a broadcast set identifier (SID). Assuming that broadcast source 1 is the target broadcast source, the address information of the target broadcast source sent by the broadcast assistant device to the broadcast receiving device may be expressed as [RPA_1, SID1, Broadcast_ID_1], or [RPA_1]. The above example is only an exemplary expression, and does not mean that the address information of the target broadcast source can only be expressed in the above form. The address information of the target broadcast source may contain at least one of the above parameters, and the order of the above parameters may be exchanged arbitrarily.

In the embodiment of this application, the broadcast source device and the broadcast assistant device can be bound in advance, and the establishment of a binding relationship between the devices allows interconnected devices to exchange and store security and identity information to establish a trust relationship. It can also be said that when If the binding relationship (Bonding) information is stored between the devices, it can be considered that the two devices can be considered as bonded (Bonded). For example, when the broadcast source enables the privacy function, the broadcast source device and the broadcast assistant device establish a binding relationship; or, the broadcast source device and the broadcast assistant device establish a binding relationship through Out of Band (OOB) .

In this application, the broadcast assistant device improves the efficiency of discovering the broadcast source when the broadcast receiving device is synchronizing and saves power consumption of the scanning device by using the enhanced low-power consumption command to read the resolvable address of the peer (as shown in Table 2).

Table 2 Enhanced Low Power Read Peer Resolvable Address Commands
