具体实施方式Detailed ways
本发明中，发明人经过了深入的思考，对现有技术进行了改进。通常，现有技术认为，可以通过LE connection interval来解决，但是当Handle太多的时候，还是比较耗时。发明人发现只要将discover到的服务信息发送给另外一个蓝牙(例如作为另外一个蓝牙蓝牙协议定义的Attribute caching)，可以大大提高连接速度，并且可以降低功耗。In the present invention, the inventor has made improvements to the prior art after in-depth thinking. Generally, the prior art considers that it can be solved by LE connection interval, but when there are too many Handles, it is still time-consuming. The inventor found that as long as the discovered service information is sent to another bluetooth (for example, as the attribute caching defined by another bluetooth bluetooth protocol), the connection speed can be greatly improved, and the power consumption can be reduced.
因此，本发明的技术问题是：解决一对蓝牙耳机如何快速与终端设备(例如手机)建立蓝牙连接(BLE连接)。应当注意的是，本发明的蓝牙连接并不等同于蓝牙配对连接。所述蓝牙连接包括第一次的蓝牙配对连接，但是不限于此。Therefore, the technical problem of the present invention is to solve how to quickly establish a Bluetooth connection (BLE connection) with a terminal device (such as a mobile phone) for a pair of Bluetooth headsets. It should be noted that the Bluetooth connection of the present invention is not equivalent to the Bluetooth pairing connection. The Bluetooth connection includes the first Bluetooth pairing connection, but is not limited thereto.
本发明采用的技术构思包括：作为一对耳机，只需要一只耳机完成对手机服务信息的发现，另外一只耳机共享即可。因此，克服了现有技术仅仅通过改变LE connectioninterval的局限。The technical concept adopted by the present invention includes: as a pair of earphones, only one earphone is needed to complete the discovery of mobile phone service information, and the other earphone can be shared. Therefore, the limitation of the prior art is overcome only by changing the LE connectioninterval.
其次，将从所述第一蓝牙耳机接收到的服务信息识别为BLE蓝牙协议中的GATT重连缓冲信息，再与所述终端设备进行所述第二BLE连接。Secondly, the service information received from the first Bluetooth headset is identified as GATT reconnection buffer information in the BLE Bluetooth protocol, and then the second BLE connection is performed with the terminal device.
本发明与常规的LE Audio相比，连接速度可以大为提高。Compared with the conventional LE Audio, the connection speed of the present invention can be greatly improved.
除非另有明确的规定和限定，本发明中所述的“或”，包含了“和”的关系。所述“和”相当于布尔逻辑运算符“AND”，所述“或”相当于布尔逻辑运算符“OR”，而“AND”是“OR”的子集。Unless otherwise expressly specified and limited, "or" described in the present invention includes the relationship of "and". The "and" is equivalent to the Boolean logical operator "AND", the "or" is equivalent to the Boolean logical operator "OR", and "AND" is a subset of "OR".

应当注意的是，所述无线通信连接只要使得所述第一蓝牙耳机和第二蓝牙耳机进行无线通信即可。所述无线通信可以采用本领域技术人员可实施的方式。It should be noted that the wireless communication connection only needs to enable the first Bluetooth headset and the second Bluetooth headset to perform wireless communication. The wireless communication can be implemented by those skilled in the art.
更具体地，所述无线通信连接不限于LE Audio连接，可以使用普通蓝牙也可以使用BLE连接。More specifically, the wireless communication connection is not limited to LE Audio connection, and can use ordinary Bluetooth or BLE connection.
如本文所用，所述“BLE连接”，是指低功耗蓝牙连接，更具体地，是指支持蓝牙协议4.0或更高的蓝牙连接。As used herein, the "BLE connection" refers to a Bluetooth low energy connection, more specifically, a Bluetooth connection that supports Bluetooth protocol 4.0 or higher.
所述的BLE连接的含义不同于BLE配对连接，这对于本领域技术人员是已知的。The meaning of the BLE connection is different from the BLE pairing connection, which is known to those skilled in the art.
如本文所用，所述“普通蓝牙”，是指支持蓝牙协议4.0以下的蓝牙连接。As used herein, the "ordinary Bluetooth" refers to a Bluetooth connection that supports the Bluetooth protocol below 4.0.
优选地，本发明的蓝牙耳机设备为TWS蓝牙耳机。Preferably, the Bluetooth headset device of the present invention is a TWS Bluetooth headset.
如图1所示，示出了LE Audio TWS连接模型。As shown in Figure 1, the LE Audio TWS connection model is shown.
所述的蓝牙耳机设备中的第一蓝牙耳机、第二蓝牙耳机可以与终端设备进行连接。The first bluetooth earphone and the second bluetooth earphone in the bluetooth earphone device can be connected with the terminal device.
所述终端设备通常为手机、音乐播放器、车载装置等具有蓝牙的终端设备。应当理解，所述终端设备可以是本领域各种具有蓝牙并可和本发明的蓝牙耳机设备配对连接的终端设备，本发明对此不做限制。The terminal equipment is usually a mobile phone, a music player, a vehicle-mounted device, or other terminal equipment with Bluetooth. It should be understood that the terminal device may be various terminal devices in the art that have Bluetooth and can be paired and connected with the Bluetooth headset device of the present invention, which is not limited in the present invention.
所述终端电子设备的个数通常为一个。由于通常连接时间太长，目前在连接上给用户带来了不好的体验。受制于此，一般最多的终端电子设备的个数也受到了限制。The number of the terminal electronic devices is usually one. Because the connection time is usually too long, a bad experience is currently brought to the user on the connection. Due to this limitation, the number of terminal electronic devices that are generally the largest is also limited.
而本发明的终端电子设备由于连接速度提高，因此连接个数不限于此。本发明的蓝牙设备可以达到与多个终端设备连接。发明人发现，本发明在所述个数的终端电子设备连接时不至于有劣化的用户体验。However, since the connection speed of the terminal electronic device of the present invention is improved, the number of connections is not limited to this. The Bluetooth device of the present invention can achieve connection with multiple terminal devices. The inventors found that the present invention will not degrade the user experience when the number of terminal electronic devices are connected.
具体如图所示，所述蓝牙耳机设备之间的连接是ACL连接。更具体地如前所述，所述ACL连接不限于LE Audio连接，可以使用普通蓝牙也可以使用BLE连接。Specifically, as shown in the figure, the connection between the Bluetooth headset devices is an ACL connection. More specifically, as mentioned above, the ACL connection is not limited to LE Audio connection, and can use ordinary Bluetooth or BLE connection.
如图2所示，示出了图1中手机与蓝牙耳机设备进行连接时需要进行的查询(discovery)服务信息(service)的过程。As shown in FIG. 2 , it shows a process of searching (discovery) service information (service) that needs to be performed when the mobile phone and the Bluetooth headset device in FIG. 1 are connected.
如本文所用，所述的“服务信息(service)”、“GATT缓存”、“GATT信息”、“ATT”都具有与现有的蓝牙协议规定的含义。As used herein, the "service", "GATT cache", "GATT information", and "ATT" all have the meanings specified in the existing Bluetooth protocol.
图2的标注框示出了一部分的蓝牙耳机查询服务，比如音乐控制服务(MediaState)，一些手机一个个的信息回复，当要查询的内容太多时，这样交互大大增加服务发现的时间。The marked box in Figure 2 shows a part of the Bluetooth headset query services, such as the music control service (MediaState), and some mobile phones reply information one by one. When there are too many contents to be queried, this interaction greatly increases the service discovery time.
应当理解，图2中的所述服务信息(Service)仅为示意，所述服务信息还可以是蓝牙协议中所规定的其他服务类信息。具体例如，MCS(音乐控制服务)，TBS(电话服务)、VCS(音量控制服务)、ASCS(音频流控制服务)、PACS(音频能力服务)、CSIS等信息，但不限于此。It should be understood that the service information (Service) in FIG. 2 is only for illustration, and the service information may also be other service type information specified in the Bluetooth protocol. For example, MCS (Music Control Service), TBS (Telephony Service), VCS (Volume Control Service), ASCS (Audio Stream Control Service), PACS (Audio Capability Service), CSIS and other information, but not limited to this.
通常，本领域一般通过提高LE connection interval(LE的连接间隔时间)来解决，当服务内容太多的时候，还是比较耗时。Usually, the solution is generally solved by increasing the LE connection interval (the connection interval time of the LE) in the art. When there are too many service contents, it is still time-consuming.
基于此，发明人构思一种技术方案，希望作为一对耳机，只需要一只耳机完成对手机服务信息的发现，另外一只耳机共享即可。具体改进方案参见图3，示出了本发明的一个具体实施方式的示意图。Based on this, the inventor conceives a technical solution, hoping that as a pair of earphones, only one earphone is needed to complete the discovery of mobile phone service information, and the other earphone can be shared. For a specific improvement scheme, refer to FIG. 3 , which shows a schematic diagram of a specific embodiment of the present invention.
图3示出了当一个耳机同一个手机连上以后，直接把Service信息发给对耳。对耳直接使用从耳省去了Discover的过程。Figure 3 shows that when a headset is connected to a mobile phone, the Service information is directly sent to the opposite ear. Direct use of the ear from the ear eliminates the process of Discover.
所述第一蓝牙耳机(左耳)配置为与终端设备之间具有BLE连接。The first Bluetooth headset (left ear) is configured to have a BLE connection with the terminal device.
所述第一蓝牙耳机(左耳)可获取来自所述终端设备(手机)的服务信息(service信息)，并将所述服务信息发送给所述第二蓝牙耳机(右耳)。The first Bluetooth headset (left ear) can acquire service information (service information) from the terminal device (mobile phone), and send the service information to the second Bluetooth headset (right ear).

图4示出了本发明的蓝牙通信系统的另一个具体实施方式。FIG. 4 shows another specific embodiment of the Bluetooth communication system of the present invention.
当BLE连接建立以后，需要完成服务发现以及配置，服务发现这个步骤主要完成发现手机提供哪些服务，同时还要对这些服务进行配置。同样手机端也需要发现耳机端的服务并进行配置。After the BLE connection is established, service discovery and configuration need to be completed. This step of service discovery mainly completes the discovery of which services the mobile phone provides, and also configures these services. Similarly, the mobile phone side also needs to discover and configure the services on the headset side.
而本发明的改进具体流程如下:And the improvement concrete flow process of the present invention is as follows:
步骤1及其后续的步骤8、10、11各自为蓝牙广播步骤。
步骤2-1和2-2为终端设备和第一蓝牙耳机之间的连接请求和连接成功步骤。Steps 2-1 and 2-2 are the connection request and connection success steps between the terminal device and the first Bluetooth headset.
对部分重复工作的改进主要包括步骤3(3-1和3-2)，步骤4(4-1和4-2)。步骤3和步骤4分别对应手机来发现和配置耳机的服务以及耳机来发现和配置手机服务(步骤5，具体包括步骤5-1和步骤5-2；和步骤6，具体包括步骤6-1和步骤6-2)。Improvements to some repetitive work mainly include steps 3 (3-1 and 3-2) and step 4 (4-1 and 4-2).

当一个耳机同一个手机连上以后，直接把当前Service信息发给对耳(步骤7)。对耳直接使用从耳(右耳)省去服务发现过程，省掉步骤3，考虑到手机不使用另外一个耳机端的缓存的服务UUID以及值，这里需要发起配置流程，步骤4不能省略，反之4也可以省略。When a headset is connected to a mobile phone, the current Service information is directly sent to the opposite ear (step 7). Direct use of the opposite ear from the ear (right ear) omits the service discovery process, and
缓存的信息包括MCS(音乐控制服务)、TBS(电话服务)、VCS(音量控制服务)、ASCS(音频流控制服务)、PACS(音频能力服务)、CSIS等信息。The cached information includes MCS (Music Control Service), TBS (Telephony Service), VCS (Volume Control Service), ASCS (Audio Stream Control Service), PACS (Audio Capability Service), CSIS and other information.
针对5、6中的手机端：For mobile terminals in 5 and 6:
当手机连接上一个耳机后，再次连一个组(成对)的耳机时，直接复用当前连接的Service信息(步骤7)。不用再做发现流程，如果耳机端支持缓存配置，可以省去配置流程，如果手机不支持任然需要发起配置流程。After the mobile phone is connected to a headset, when a group (paired) headset is connected again, the currently connected Service information is directly multiplexed (step 7). There is no need to do the discovery process. If the headset supports cache configuration, the configuration process can be omitted. If the mobile phone does not support it, the configuration process still needs to be initiated.
通过上面的步骤，在第一次配对的时候耳机端和手机端直接复用第一个连接上的所有服务信息。这样大大提供了连接速度。当配对完以后，第二次连接使用GATT Cashing机制加快连接速度，从耳改善了LE Audio TWS应用体验(步骤9，包括步骤9-1和9-2)。Through the above steps, when pairing for the first time, the headset end and the mobile phone end directly multiplex all the service information on the first connection. This greatly improves the connection speed. After pairing, the second connection uses the GATT Cashing mechanism to speed up the connection and improve the LE Audio TWS application experience from the ear (step 9, including steps 9-1 and 9-2).
如果当前手机没有同耳机连接过，没有GATT Caching。所以在第一次连接配对的时候，服务发现和配置会带来一定的时间开销步骤1和步骤2部分(包括步骤2-1和步骤2-2)If the current phone is not connected to the headset, there is no GATT Caching. Therefore, when the first connection is paired, service discovery and configuration will bring a certain time overhead.
这里采用把已经discover完成的连接信息发送给另外一个耳机，作为另一个耳机的Attribute caching。Here, the connection information that has been discovered is sent to another headset as attribute caching for the other headset.
综上所述，发明人利用了蓝牙协议定义的Attribute caching功能，当重连的时候可以直接使用缓存的Attribute Handles，不用再去做discover流程。In summary, the inventor uses the attribute caching function defined by the Bluetooth protocol, and can directly use the cached Attribute Handles when reconnecting, without having to go through the discovery process.
此外，再与第N个终端电子设备连接时，可以继续续复用第一个连接上的所有服务信息(步骤10-12)。这样大大提供了连接速度。In addition, when connecting to the Nth terminal electronic device, all the service information on the first connection can be continuously reused (steps 10-12). This greatly improves the connection speed.
本发明的原理如下，The principle of the present invention is as follows,
将从所述第一蓝牙耳机接收到的服务信息识别为BLE蓝牙协议中的GATT重连缓冲信息，再与所述终端设备进行所述第二BLE连接。The service information received from the first Bluetooth headset is identified as GATT reconnection buffer information in the BLE Bluetooth protocol, and then the second BLE connection is performed with the terminal device.
第二个耳机BLE ACL连接上以后，上层服务信息完全复用第一只耳机的信息，所以时间开销只在耗费在连接第二个耳机的BLE ACL Link(BLE连接)上，从而能够克服上述连接慢的技术缺点，使用LE Audio带来更好的体验。After the second headset BLE ACL is connected, the upper-layer service information completely reuses the information of the first headset, so the time overhead is only spent on the BLE ACL Link (BLE connection) connecting the second headset, which can overcome the above connection. Slow technical shortcomings, using LE Audio brings a better experience.
应当理解的是，本发明的第一蓝牙耳机和第二蓝牙耳机与终端设备均为实体连接，因此主从耳机之间不同于监听方案中的主从关系。本发明提供了一种替代监听方案的蓝牙连接方式。同时，改善了现有的监听替代方案的连接时间太长的问题。It should be understood that the first Bluetooth headset and the second Bluetooth headset of the present invention are all physically connected to the terminal device, so the master-slave headset is different from the master-slave relationship in the monitoring solution. The present invention provides a bluetooth connection mode that replaces the monitoring scheme. At the same time, the problem that the connection time of the existing monitoring alternative is too long is improved.
更优选的是，本发明的连接方案同样适用于接入多个蓝牙、或是多个终端的应用场景。More preferably, the connection solution of the present invention is also applicable to the application scenario of accessing multiple Bluetooth or multiple terminals.
更需要指出的是，本发明选择了节省服务信息的时间花销，因此使得连接时间大为减少，达到数秒以上(例如2-3秒等)，获得了预期之外的效果。It should be pointed out that the present invention chooses to save the time cost of service information, so the connection time is greatly reduced, reaching more than a few seconds (for example, 2-3 seconds, etc.), and an unexpected effect is obtained.
本发明的效果如下，The effects of the present invention are as follows,
(1)不需要双耳都做discover服务，优化了连接速度，降低了功耗。例如，(1) There is no need for both ears to do the discovery service, which optimizes the connection speed and reduces power consumption. E.g,
(2)在LE Audio应用中，手机需要同两个耳机分别建立连接，建立连接后分别发现以及配置服务，这里第二个连接的耳机只需要花费BLE ACL连接的时间，服务配置信息完成复用第一个连接上的耳机。这样加快了连接过程。同时可以连接多个终端电子设备而不会影响连接速度。(2) In the LE Audio application, the mobile phone needs to establish a connection with the two earphones respectively. After the connection is established, the service is discovered and configured respectively. Here, the second connected earphone only needs to spend the time of the BLE ACL connection, and the service configuration information is multiplexed. The first connected headset. This speeds up the connection process. Multiple terminal electronic devices can be connected at the same time without affecting the connection speed.
