Background

In the existing bluetooth communication system, the broadcast receiving device is typically a battery-powered embedded device, and the process of performing the scan for finding the broadcast source consumes much power, so that the broadcast receiver generally requests the broadcast assistant device to perform the scan for finding the broadcast source, and when the broadcast assistant device scans for the broadcast source, the broadcast assistant device sends the related information of the broadcast source to the broadcast receiver. However, when the same broadcast source device broadcasts multiple broadcast sources simultaneously, the broadcast assistant device cannot acquire the related information of the designated broadcast sources respectively, and can only acquire the related information of the designated broadcast sources by scanning all the nearby broadcast sources, which is very low in efficiency and serious in power consumption of the scanning device, so that the broadcast receiving device cannot receive the audio information of the designated broadcast sources quickly.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings. It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" is used herein to describe association of associated objects, for example, to indicate that there may be three relationships between the associated objects, for example, a and/or B, may indicate: three cases of A alone, A and B together, and B alone exist. The character "/" herein generally indicates that the context associated object is an "or" relationship.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided by the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided by the embodiments of the present application is 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 present application is described by taking an audio broadcast signal as an example, 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 scenes in which signals such as video, image, augmented Reality (Augmented Reality, AR), virtual Reality (VR) and the like are transmitted.

The low power audio technology provides powerful bluetooth functions for the wireless audio market, including: brand new higher quality, more efficient audio codec capability, capability to transmit multiple audio streams simultaneously, new bluetooth audio broadcast functionality, and capability to transmit audio with bluetooth low energy, etc.

In the low power consumption audio technology, low power consumption broadcast audio involves a basic audio Profile (Basic Audio Profile, BAP), a Profile (Profile) of a broadcast audio scanning Service (Broadcast Audio Scan Service, BASS), and a Service (Service).

Wherein the broadcast audio scanning service relates to a related process of discovering a broadcast source in a broadcast audio processing system. The Broadcast audio processing system includes a Broadcast receiving device (Broadcast Sink), a Broadcast assistant (Broadcast Assistant) device, and a Broadcast Source (Broadcast Source) device. Fig. 1A and 1B show two possible topologies of a broadcast audio processing system, 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 headset, and a portable terminal device, such as a mobile phone, may be used as a broadcast assistant device to broadcast an audio stream with a broadcast source device such as a television or a computer.

As shown in fig. 1B, the broadcast source device and the broadcast assistant device may 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, may be used as a broadcast assistant device, and broadcast an audio stream in synchronization with the portable terminal device, which is a broadcast source device at the same time.

In one embodiment of the present application, the broadcast source device and the broadcast assistant device may be configured on different devices, and in general, the broadcast receiving device and the broadcast source device broadcast the audio data stream synchronously, and need to perform the operation of scanning to find the broadcast source, and the broadcast receiving device needs to consume a certain amount of electric energy in the scanning process. And the broadcast receiving device is typically an embedded device that is powered by a battery, the broadcast receiving device requests the broadcast assistant device to perform an operation of scanning for the discovery broadcast source. Based on this, the broadcast receiving apparatus may also be referred to as a Scan Delegator (Scan Delegator).

The broadcast assistant apparatus generally includes a scan Host (Scanner Host) and a scan controller (Scanner Controller), and when the broadcast assistant apparatus performs a scan operation, if a broadcast source is found, the broadcast assistant apparatus transmits related information of the broadcast source to a broadcast receiver through an add broadcast source operation (Add Source Operation) defined in a Broadcast Audio Scan Service (BASS).

Due to the provision of existing specification Basic Audio Profiles (BAPs) and privacy concerns, broadcast assistant devices cannot directly use Identity Addresses (IA) when performing an add broadcast source operation, but rather use resolvable private addresses (Resolvable Private Address, RPA).

When there is only one broadcast information transmitted from the broadcast source, the scan controller transmits the Resolvable Private Address (RPA) used by the opposite terminal to the host device, and the broadcast assistant device transmits the Resolvable Private Address (RPA) to the broadcast receiving device. The broadcast receiving apparatus uses a faster way to achieve synchronization with the broadcast source.

In one embodiment of the application, a manner (Filter Accept List) of filtering a received list based on a Resolvable Private Address (RPA) may be used to improve the efficiency of discovering broadcast sources and save power consumption of scanning devices.

During the broadcast process, one broadcast source device may transmit broadcast information from a single broadcast source stream to multiple broadcast receiving devices using a set of synchronized streams. Each stream is called a broadcast synchronization stream (Broadcast Isochronous Stream, BIS). One set of BIS is called a broadcast synchronization group (Broadcast Isochronous Group, BIG). For example, televisions transmit broadcast audio data streams to multiple receivers, such as different individuals wearing earplugs. One broadcast source device may have multiple broadcast sources, i.e., multiple broadcast synchronization groups (BIG) may be created.

A broadcast source specified in the Broadcast Audio Scanning Service (BASS) may be identified by triple information [ Address Type (address_address_type), address (address_address), broadcast Set ID (SID) ].

The Broadcast synchronization stream (BIS) may be identified by a Broadcast identification (broadcast_id) transmitted from the Broadcast source device to the scanning device.

When a broadcast source device transmits broadcast information of a plurality of broadcast sources, a situation may occur that a broadcast assistant device cannot acquire a designated broadcast source address, as shown in a flowchart in fig. 5, which specifically includes:

s51, the broadcast source device establishes a binding (bound) relationship with the broadcast assistant device, and the broadcast source device enables a privacy mode (Controller-based privacy) to prevent addresses from being tracked.

S52, the broadcast source device sends broadcast information to the broadcast assistant device, where the broadcast information is 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 to the broadcast assistant device, the two broadcast information are from two broadcast sources, and the two broadcast sources generate two different RPAs (e.g. rpa_1 and rpa_2 are respectively carried in broadcast information 1 and broadcast information 2 by using the same identity resolution key (Identity Resolving Key and IRK).

S53, the broadcast assistant device completes the operation of scanning for the discovery broadcast source. Specifically, the scan controller obtains the broadcast information by scanning, and the scan host may obtain the Resolvable Private Address (RPA) used by the opposite end by sending a low-power-consumption read opposite end resolvable address command (LE Read Peer Resolvable Address command, as shown in table 1) to the scan controller, because the broadcast information 1 and the broadcast information 2 come from different broadcast sources, when the scan controller receives the broadcast information sent by the two broadcast sources, the scan controller resolves the two different Resolvable Private Addresses (RPA) into the same Identity Address (IA) and sends the same Identity Address (IA) to the scan host, that is, LE Read Peer Resolvable Address command cannot obtain the address information of the two broadcast sources respectively, so that failure information can be directly returned.

TABLE 1 Low Power consumption read counter resolvable Address Command

The low power consumption read peer-to-peer resolvable address command is used to obtain the resolvable private address of the peer-to-peer public random identity address currently being used. The type of the opposite end Identity Address (IA) occupies 1 byte (Octet), the opposite end identity address occupies 6 bytes (Octet), the state occupies 1 byte (Octet), and the opposite end resolvable address occupies 6 bytes (Octet).

S54, in the existing specification Basic Audio Profile (BAP), it is specified that the Broadcast audio source device assigns a unique Broadcast identifier, that is, a Broadcast identifier (broadcast_id), to each Broadcast synchronization stream information, and when the Broadcast assistant device performs adding a Broadcast source, the Broadcast source address is typically set to 0 (or a full 0 sequence) for security consideration, and at the same time, the Broadcast identifier (broadcast_id) is sent to the Broadcast receiving device.

S55, the Broadcast receiving apparatus performs a matching lookup using a broadcast_id (broadcast_id), thereby implementing synchronization of the Broadcast audio data stream.

And S56, the broadcast receiving device sends the 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 and tries to resynchronize, the Broadcast receiving device needs to scan all Broadcast information of surrounding Broadcast sources, and sequentially judges whether Broadcast identification (broadcast_ID) of the Broadcast information is matched, if so, the scanning is stopped, the resynchronization is established, and otherwise, the scanning operation is continuously executed.

When the Broadcast receiving device stops synchronizing to the Broadcast source and attempts synchronization again, the synchronization can be realized only by scanning all surrounding Broadcast sources and judging the Broadcast identification (broadcast_id) in turn, and the existing synchronization scheme ensures that the Broadcast receiving device consumes more time and electricity to realize the synchronization with the Broadcast source.

It should be understood that the target broadcast source referred to in the present application refers to a broadcast source to be synchronized by the broadcast receiving apparatus.

The scheme provided by the embodiment of the application is mainly used for solving at least one of the problems.

For a more complete understanding of the nature and the technical content of the embodiments of the present application, reference should be made to the following detailed description of embodiments of the application, taken in conjunction with the accompanying drawings, which are meant to be illustrative only and not limiting of the embodiments of the application.

Embodiments of the present application provide a method for bluetooth communication, which may be applied to or performed by a broadcast assistant device. Referring to fig. 2, the method includes:

s201, receiving broadcast information transmitted by a broadcast source device, the broadcast information being transmitted by at least one broadcast source, the at least one broadcast source including a target broadcast source.

In one embodiment of the present application, the Broadcast information may include a Broadcast identification (broadcast_id), a Broadcast Set Identification (SID), a Resolvable Private Address (RPA), etc. Illustratively, when there are two Broadcast sources, respectively denoted as Broadcast source 1 and Broadcast source 2, broadcast information of Broadcast source 1 may be denoted as [ Broadcast 1, rpa_1, sid1, broadcast_id_1], and Broadcast information of Broadcast source 2 may be denoted as [ Broadcast 2, rpa_2, sid2, broadcast_id_2].

The above example is merely an exemplary expression, and broadcast information not representing a limiting broadcast source may be represented in the above form only. 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 arbitrarily exchanged.

In one embodiment of the present application, the broadcast source 1 is taken as a target broadcast source in the present application as an example, and alternatively, the broadcast source 2 may also be taken as a target broadcast source. When there are more than two broadcast sources, it may also be assumed that broadcast source 3[Broadcast 3,RPA_3,SID3,Broadcast_ID_3 is a target broadcast source, or the like.

In one embodiment of the present application, the target broadcast source may be a broadcast source that has been synchronized before the broadcast receiving apparatus and attempted to be synchronized again, or may be a broadcast source that has been synchronized for the first time by the broadcast receiving apparatus.

In one embodiment of the present application, the target broadcast source may be one broadcast source that needs to be synchronized by the broadcast receiving device in the at least one broadcast source, or may be multiple broadcast sources that need to be synchronized by the broadcast receiving device in the at least one broadcast source.

S202, sending the address information of the target broadcast source to a broadcast receiving device.

In one embodiment of the application, the broadcast assistant apparatus may transmit address information of a plurality of target broadcast sources at a time.

In one embodiment of the present application, the broadcast assistant apparatus may transmit address information of a plurality of target broadcast sources, respectively.

In one embodiment of the present application, the address information of the target Broadcast source may include a Resolvable Private Address (RPA), a Broadcast identification (broadcast_id), and a Broadcast Set Identification (SID). Assuming that broadcast source 1 is a target broadcast source, address information of the target broadcast source transmitted by the broadcast assistant device to the broadcast receiving device may be expressed as [ rpa_1, sid1, broadcast_id_1], or as [ rpa_1]. The above example is merely an exemplary expression, and address information not representing a restriction target broadcast source may be represented only 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 arbitrarily exchanged.

The embodiment of the application provides a Bluetooth communication method, which can be applied to or executed by broadcast source equipment. Referring to fig. 3, the method includes:

s301, transmitting broadcast information, where the broadcast information is transmitted by at least one broadcast source, and the at least one broadcast source includes a target broadcast source.

In one embodiment of the present application, the broadcast source apparatus may transmit broadcast information of one or more broadcast sources.

The embodiment of the application provides a Bluetooth communication method, which can be applied to or executed by broadcast receiving equipment. Referring to fig. 4, the method includes:

s401, receiving address information of a target broadcast source sent by the broadcast assistant equipment.

In one embodiment of the present application, the address information of the target Broadcast source may include a Resolvable Private Address (RPA), a Broadcast identification (broadcast_id), and a Broadcast Set Identification (SID).

In the embodiment of the application, the broadcast source device and the broadcast assistant device can be bound in advance, the binding relationship between the devices allows the security and identity information to be exchanged and stored between the devices connected with each other to establish a trust relationship, so to speak, when binding relationship (binding) information is stored between the devices, the two devices can be considered to be bound (bound). For example, in the case of a broadcast source enabled privacy function, the broadcast source device and the broadcast assistant device establish a binding relationship; alternatively, the broadcast source device and the broadcast assistant device establish a binding relationship by Out of Band (OOB) means.

The broadcast assistant device in the application can analyze the address command (shown in table 2) by using the enhanced low-power consumption reading opposite terminal, thereby improving the efficiency of finding the broadcast source when the broadcast receiving device is synchronous and saving the power consumption of the scanning device.

Table 2 enhanced Low Power reading peer-resolvable Address Command

The enhanced low-power consumption reading opposite terminal resolvable address command, or the low-power consumption reading opposite terminal resolvable address command [ v2] is mainly different from the low-power consumption reading opposite terminal resolvable address command specified in the prior art in that the broadcasting set identifier is carried, and the broadcasting assistant equipment can be assisted to identify the address information of the target broadcasting source.

In the following, with two specific examples, implementation of a method for performing bluetooth communication by an enhanced low energy read peer-resolvable address command assisted broadcast assistant device is described in a specific scenario.

When the broadcast source device and the broadcast assistant device are configured on different devices, as shown in fig. 6, specific steps include:

s61, the broadcast source device enables the privacy function, i.e. uses the resolvable private address to communicate with the broadcast assistant device. The broadcast source device establishes a binding relationship with the broadcast assistant device.

S62, the Broadcast source device transmits Broadcast information 1 and Broadcast information 2 to the Broadcast assistant device, respectively, and the two Broadcast information may be transmitted in the form of [ Broadcast 1, rpa_1, sid1, broadcast_id_1] and [ Broadcast 2, rpa_2, sid2, broadcast_id_2], respectively.

S63, the scan controller of the broadcast assistant apparatus scans receivable broadcast information. It is assumed that both broadcast information 1 and broadcast information 2 can be scanned by the scan controller of the broadcast assistant apparatus.

S64, after the scanning controller scans the broadcast information, the scanning controller analyzes the Resolvable Private Address (RPA) of the broadcast information into an Identity Address (IA), and reports the Identity Address (IA) to the scanning host, wherein the reported events are respectively recorded as a low-power-consumption broadcast report event 1 (IA, SID 1) and a low-power-consumption broadcast report event 2 (IA, SID 2).

S65, after receiving the event reported by the scanning controller, the scanning host sends an enhanced low-power consumption reading opposite terminal resolution address command to the scanning controller, and reads target resolvable address information from the scanning controller, wherein the enhanced low-power consumption reading opposite terminal resolution address command at least comprises a broadcasting set identifier (SID 1) and an Identity Address (IA) of a target address.

And S66, when the scanning controller receives the enhanced low-power consumption reading opposite terminal resolution address command, if the opposite terminal identity address information carried in the enhanced low-power consumption reading opposite terminal resolution address command is found to correspond to a plurality of scanned identity address information, namely to a plurality of opposite terminal broadcast sources, the target broadcast requested by the scanning host is determined by combining the opposite terminal broadcast set identifier.

S67, the scanning controller feeds back the resolvable private address (RPA_1) of the target broadcast source to the scanning host.

S68, the broadcast assistant device feeds back the resolvable private address (RPA_1) of the target broadcast to the broadcast receiving device.

In one embodiment of the present application, after receiving the resolvable private address (rpa_1) of the target broadcast, the broadcast receiving device may use a manner (Filter Accept List) of filtering the receiving list based on the Resolvable Private Address (RPA) to improve the efficiency of discovering the broadcast source, achieve data stream synchronization, and save the power consumption of the scanning device.

In one embodiment of the present application, the broadcast assistant apparatus may further feed back at least one of the following information to the broadcast receiving apparatus: a Broadcast set identification (SID 1) of the target Broadcast source, a Broadcast identification (broadcast_id_1) of the target Broadcast source.

In one embodiment of the present application, when the broadcast source device transmits broadcast information of more than two broadcast sources, the enhanced low power consumption reading peer-to-peer address resolution command may carry broadcast set identifiers of one or more peer broadcast sources.

In one embodiment of the present application, the address command of the enhanced low power consumption reading opposite terminal carries a broadcast Set Identifier (SID) of a plurality of target broadcasts, and the scan controller may report address information of the plurality of target broadcasts to the scan host separately or together.

In one embodiment of the present application, the broadcast assistant apparatus may transmit address information of a plurality of target broadcasts to the broadcast receiving apparatus separately or together.

In one embodiment of the present application, when the broadcast source device only broadcasts the broadcast information of one broadcast source, the scan controller may directly report the address information of the target broadcast to the scan host after receiving the address resolution command of the enhanced low power consumption reading opposite terminal, and the broadcast assistant device directly transmits the address information of the target broadcast to the broadcast receiving device.

In one embodiment of the present application, the address of the target broadcast source may be the address of the broadcast source that was last synchronized by the broadcast receiving device, i.e., resynchronization. The broadcast Set Identification (SID) of the target broadcast source is stored in the directory of the broadcast receiving device or broadcast assistant device during the last synchronization.

In one embodiment of the present application, the address of the target broadcast source may be the address of the broadcast source that the broadcast receiving apparatus first synchronizes, i.e., first synchronizes. The target broadcast specifies or embeds a broadcast Set Identification (SID) for the user for the default or highest priority broadcast source.

The above is merely an exemplary expression, the order of the above steps is not limited, and the respective steps may be combined with each other or the order may be exchanged.

Specific arrangements and implementations of embodiments of the present application have been described from various angles by the various embodiments above. With the above at least one embodiment, when the broadcast source device transmits the broadcast information of at least one broadcast source, the broadcast assistant device may acquire the address information of the opposite broadcast source using the enhanced low power consumption read opposite resolution address command, thereby reducing the time for the broadcast receiving device to synchronize to the target broadcast source and saving the power consumption of the scanning device.
