Specific embodiment

The application provides a kind of processing method of bluetooth data packets, and this method, which can be applied, is establishing the two of bluetooth connection Between a bluetooth equipment.Fig. 1 is a kind of schematic diagram for the network architecture that the application is applicable in, as shown in Figure 1, the network architecture includes Two bluetooth equipments: the first bluetooth equipment and the second bluetooth equipment.In framework shown in Fig. 1, the first bluetooth equipment be mobile phone, second Bluetooth equipment is bluetooth headset, is communicated between mobile phone and bluetooth headset by bluetooth connection.

It is appreciated that the first bluetooth equipment is not limited to mobile phone, the second bluetooth equipment is also not necessarily limited to bluetooth headset.First bluetooth Equipment and the second bluetooth equipment all can be any electronic equipments bluetooth-capable.For example, the first bluetooth equipment and second Bluetooth equipment all can be mobile phone, tablet computer, handheld computer, laptop, Ultra-Mobile PC (Ultra- Mobile Personal Computer, UMPC), net book, cellular phone and personal digital assistant (Personal Digital Assistant, PDA), wearable device (such as Intelligent bracelet, smartwatch, intelligent glasses, intelligent helmet), Mobile unit, intelligent sound box, augmented reality (augmented reality, AR) virtual reality (virtual reality, VR) It is equipment, the wireless terminal in Industry Control (industrial control), wireless in unmanned (self driving) Terminal, the wireless terminal in tele-medicine (remote medical), the wireless terminal in smart grid (smart grid), fortune Wireless terminal, the wireless terminal in smart city (smart city), intelligence in defeated safety (transportation safety) The equipment such as the wireless terminal in intelligent family (smart home).

By taking mobile phone and mobile unit as an example, mobile phone and mobile unit are established after bluetooth connection, and mobile phone is available vehicle-mounted The ability characteristics parameter (features) that equipment is supported, ability characteristics parameter are used to characterize the energy of current Bluetooth equipment transmission data Power.Mobile phone can be ordered by HCI Read Supported Features Complete () and obtain opposite end bluetooth equipment Feature capabilities parameter.

The ability characteristics parameter that bluetooth equipment is supported can be indicated by form as shown in Table 1:

Table one

The title (or mark) of ability characteristics parameter	Value
		Ability characteristics parameter one	yes
Ability characteristics parameter two	no
		……
Ability characteristics parameter N	Yes

The value of ability characteristics parameter can be that " being (yes) " or " no (no) " indicates equipment branch when value is "Yes" The ability characteristics parameter is held, when value is "No", indicates that equipment does not support the ability characteristics parameter.

It include the type information for the data packet that the mobile unit is supported, data in the ability characteristics parameter that mobile unit is supported The type information of packet is, for example, 1M, 2M etc..

Certainly, the ability characteristics parameter that bluetooth equipment is supported is not limited to the type of data packet of bluetooth equipment support, can be with Including one or more in following parameter: 3 time slot data packets (3slot packets), 5 time slot data packet (3slot Packets), role transforming (role switch), power supply control (power control), slot offset (slot offset), Synchronization link (SOC link) etc..

Currently, the type of data packet that bluetooth equipment is supported includes 1M, 2M and 3M data packet.The opposite end bluetooth that mobile phone is got The type information for the data packet that equipment is supported can be with are as follows: " enhanced data rate ACL 2Mbps mode (i.e. 2M data Packet) " and/or " enhanced data rate ACL 3Mbps mode (i.e. 3M data packet) ".

If opposite end bluetooth equipment is declared in ability characteristics parameter oneself supports 3M data packet, mobile phone is according to getting The ability characteristics parameter of bluetooth equipment, the type that the data packet sent to bluetooth equipment can be set is 3M data packet.If right End bluetooth equipment is declared in ability characteristics parameter oneself supports 2M data packet, and mobile phone is special according to the ability of the blue equipment got Parameter is levied, the type that the data packet sent to opposite end bluetooth equipment can be set is 2M data packet.In the class for setting data packet After type, mobile phone sends data packet to opposite end bluetooth equipment according to the type of the data packet, and subsequent opposite end bluetooth equipment can root According to the type of the requirement request mobile phone switch data packet of oneself.

Optionally, mobile phone and bluetooth equipment are established after connection, and mobile phone can not obtain support to opposite end bluetooth equipment The type of data packet, but the type of the data packet sent to opposite end bluetooth equipment is set oneself.

In some scenes, although bluetooth equipment states that oneself supports 2M or 3M data packet in ability characteristics parameter, Be, since bluetooth equipment data-handling capacity is limited, cause bluetooth equipment can not handle mobile phone transmission all data packets, thus Abandon partial data packet.When bluetooth equipment is mobile unit, abandoning partial data packet will lead to music Caton, and user experience is not It is good.

In the embodiment of the present application, the data-handling capacity of bluetooth equipment can be the processing speed of bluetooth equipment, processing speed Degree is the size of the data volume handled in unit time (such as 1 second), if mobile phone is within the unit time to opposite end bluetooth equipment The data volume of transmission is greater than processing speed, then the data volume in the buffer (buffer area) of opposite end bluetooth equipment will be more than buffer Capacity threshold, bluetooth equipment can only lose a part of data.

In other scenes, the data packet of the size and opposite end bluetooth equipment support of the data packet of mobile phone oneself setting Size mismatches, so as to cause data packet discarding.For example, the size of the data packet for being sent to opposite end bluetooth equipment of mobile phone setting For 3M data packet, and bluetooth equipment is practical only supports 2M data packet, so, the data packet that mobile phone is sent can not be complete by bluetooth equipment Portion's processing, so as to cause data packet discarding.

In a kind of possible embodiment, blacklist is can be used to limit specific bluetooth equipment, for example, working as data in mobile phone Transmission rate compared in the slow or higher situation of packet loss, can by record specific bluetooth equipment identity (such as The address mac, ID etc.), when mobile phone is connected to the bluetooth equipment in blacklist, mobile phone, which can directly be defaulted, sends 1M's or 2M Data packet, even if opposite end bluetooth equipment supports the ability of 3M data packet transmission.

In order to solve the problems, such as bluetooth equipment due to the limited caused packet loss of data-handling capacity, the embodiment of the present invention one is provided A kind of processing method of bluetooth data packets, Fig. 2 are the process of the processing method for the bluetooth data packets that the embodiment of the present invention one provides Figure, as shown in Fig. 2, method provided in this embodiment the following steps are included:

S101, the first bluetooth equipment obtain the type of data packet that the second bluetooth equipment is supported, which includes the One type and Second Type.

Illustratively, the first bluetooth equipment sends the second request to the second bluetooth equipment, and the second request is for requesting second The ability characteristics parameter that bluetooth equipment is supported.

First bluetooth equipment can establish asynchronous connection (asynchronous connection- with the second bluetooth equipment Oriented link, ACL) after link, second request is sent to the second bluetooth equipment, the ACL link, that is, bluetooth connection, First bluetooth equipment and the second bluetooth equipment can pass through message: HCI create connection establishes ACL link.ACL Referring to prior art, the present embodiment does not illustrate the process for establishing connection of link.

The ability characteristics that second request is supported for the second bluetooth equipment of request, which can be HCI Read Remote Supported Features order.

Second bluetooth equipment sends the response of the second request to the first bluetooth equipment, includes second in the response of the second request The ability characteristics parameter that bluetooth equipment is supported.

Second bluetooth equipment generates the response of the second request according to the second request, includes the in response of second request Two bluetooth equipments support ability characteristics parameter, the second bluetooth equipment support ability characteristics parameter in include but is not limited to second The type of data packet information that bluetooth equipment is supported, which includes but is not limited to the first kind and Second Type.Data Packet type, that is, data packet size, the first kind can be 3M data packet, and Second Type is 2M data packet, alternatively, the first kind For 2M data packet, Second Type is 1M data packet.

When the second request is HCI Read Remote Supported Features order, the response of second request For HCI Read Remote Supported Features response message.

S102, the first bluetooth equipment send the first data to second the first bluetooth equipment of bluetooth equipment according to the first kind.

After first bluetooth equipment gets the type of data packet of the second bluetooth equipment support, supported according to the second bluetooth equipment Type of data packet be arranged to the second bluetooth equipment send type of data packet, and according to the type of data packet of setting with second indigo plant The communication of tooth equipment.

In the present embodiment, it is the first kind that the type of data packet sent to the second bluetooth equipment, which is arranged, in the first bluetooth equipment, The first data are sent to the second bluetooth equipment using the corresponding data packet of the first kind.Under normal conditions, the first bluetooth equipment meeting The maximum data Packet type for selecting the second bluetooth equipment to support sends data to the second bluetooth equipment.

Optionally, the first bluetooth equipment is after determining the type of data packet sent to the second bluetooth equipment, to the second indigo plant Tooth equipment sends the type of data packet.

S103, the first bluetooth equipment receive the first request that the second bluetooth equipment is sent, which cuts for requesting Change the first kind.

Second bluetooth equipment sends the first request to the first bluetooth equipment in response to the first trigger event.

First bluetooth equipment and the second bluetooth devices for a period of time after, the second bluetooth equipment can be received according to current The ability of data packet, environmental disturbances degree, received signal strength indicator (received signal strength indication, RSSI), the parameters such as packet loss determine switch data Packet type.Correspondingly, the first trigger event is that the second bluetooth equipment currently connects It receives the parameters such as ability, environmental disturbances degree, RSSI, packet loss, the time delay of data packet and meets preset condition.

For example, the type of data packet that the second bluetooth equipment is supported is 3M, when the first bluetooth equipment and the second bluetooth equipment After distance zooms out, bluetooth signal intensity dies down, and bluetooth signal intensity, which dies down, will lead to the first bluetooth equipment and the second bluetooth equipment Between transmission speed reduce, after transmission rate is slack-off, the delay of 3M data packet is larger, and the time delay of data packet, which is unable to satisfy, to be wanted It asks, the second bluetooth equipment, which is determined, is switched to 2M data packet from 3M data packet for the type of data packet.

After the first bluetooth equipment furthers at a distance from the second bluetooth equipment, bluetooth signal intensity becomes strong, and bluetooth is set at this time It is standby the type of data packet to be switched to 3M data packet from 2M data packet.

For another example, when the first bluetooth equipment sends the data packet of 3M, since the processing speed of the second bluetooth equipment is limited, example Data packet as sent in the first bluetooth equipment unit time is too many, and the processing of the second bluetooth equipment does not come, it is determined that by data The type of packet is switched to 2M data packet from 3M data packet.

After second bluetooth equipment determines switch data Packet type, the first request is sent to mobile phone.Optionally, this first is asked It may include the information for the target data Packet type that the expectation of the second bluetooth equipment is switched in asking.

Wherein, target data Packet type can be carried by 1 or multiple bits, such as include one in first message A type of data packet field, the field occupy dibit, and dibit can indicate type in 4 altogether.For example, 00 indicates 1M data Packet, 01 indicates 2M data packet, and 10 indicate 3M data packet, and 11 be reserved value.

First request can be the message newly defined, can also be using existing message, illustratively, which can Think existing LMP Power Control request message, LMP Power Control request message is for requesting The power of bluetooth equipment is tuned up into maximum or minimum, alternatively, tuning up or turning down a grade for the power of bluetooth equipment.

S104, it is requested in response to first, the first bluetooth equipment determines that the first bluetooth equipment and the second bluetooth devices make The channel quality of bluetooth channel meets preset channel quality requirement.

In a kind of illustrative mode, the first bluetooth equipment obtains the channel quality information of bluetooth channel, the channel quality Information includes at least one of following parameter: the RSSI of the second bluetooth equipment, the frequency of switch data Packet type, transmit queue Buffer size, the number of retransmissions of data packet and the Packet Error Ratio of data packet, according to the channel quality information and the channel matter Amount requires, and determines that the channel quality of bluetooth channel meets the channel quality requirement.

First bluetooth equipment and the second bluetooth equipment are in communication process, and the first bluetooth equipment can be detected and be recorded: second The re-transmission of the frequency, the buffer size, data packet of the transmit queue of the second bluetooth equipment of bluetooth equipment switch data Packet type The Packet Error Ratio of number and data packet.

Wherein, the frequency of the second bluetooth equipment switch data Packet type refers to the second bluetooth equipment (example within the unit time Such as 1 minute) in switching type of data packet number.The number of retransmissions of data packet refers to the first bluetooth equipment within the unit time The number for the data packet that (such as 1 minute) is retransmitted to the second bluetooth equipment.The Packet Error Rate of data packet refers to that the first bluetooth equipment exists The ratio of the number of the number and total data packet for the erroneous packets that (such as 1 minute) is sent to the second bluetooth equipment in default detection time Value.

When the channel quality information includes the RSSI of the second bluetooth equipment, the first bluetooth equipment may determine that the second bluetooth Whether the RSSI of equipment is greater than preset RSSI threshold value, when the second bluetooth equipment RSSI be greater than preset RSSI threshold value the case where Under, the first bluetooth equipment determines that the channel quality of bluetooth channel meets channel quality requirement.When the second bluetooth equipment RSSI not In the case where greater than (being less than or equal to) preset RSSI threshold value, the first bluetooth equipment determines the channel quality of bluetooth channel not Meet channel quality requirement.

The RSSI value of second bluetooth equipment is less than or equal to RSSI threshold value, illustrates that bluetooth signal intensity is weak, usual bluetooth letter Number intensity is weak be by the distance between two bluetooth equipments it is remote caused by, the second bluetooth equipment requests switch data packet in this case Type is far to be triggered by distance between two bluetooth equipments, rather than not due to the data-handling capacity of the second bluetooth equipment It enough triggers, therefore, the first bluetooth equipment determines not switch data Packet type.

The RSSI value of second bluetooth equipment is greater than RSSI threshold value, illustrates that bluetooth signal intensity is strong, between two bluetooth equipments Distance bluetooth equipment normal communication distance in.In this case, the second bluetooth equipment requests switch data Packet type, it is not It is remote caused by the distance between mobile phone and bluetooth equipment, but since the data-handling capacity of the second bluetooth equipment not enough triggers , therefore, the first bluetooth equipment determines switch data Packet type.

Optionally, in the case that the RSSI of the second bluetooth equipment is greater than preset RSSI threshold value, the first bluetooth equipment is sentenced The frequency of disconnected second bluetooth equipment switch data Packet type, the buffer size of transmit queue, data packet number of retransmissions and Whether at least one of Packet Error Ratio of data packet meets corresponding threshold value, when the switch data Packet type of the second bluetooth equipment At least one of frequency, the buffer size of transmit queue, the number of retransmissions of data packet and Packet Error Ratio of data packet meet When corresponding threshold value, the first bluetooth equipment determines that the channel quality of bluetooth channel meets channel quality requirement.

Illustratively, in the case where RSSI > -83dBm of TXq=28 and the second bluetooth equipment, if Fpkt >=6, Tcnt >=12 or Err >=5%, then the first bluetooth equipment determines that the channel quality of bluetooth channel meets channel quality requirement, needs Want switch data Packet type.Wherein, TXq indicates buffer size (the TX queue of the transmit queue of the second bluetooth equipment Buffer size), Fpkt indicates the frequency of the second bluetooth equipment switch data Packet type, and Tcnt indicates the re-transmission time of data packet Number, Err indicate the Packet Error Ratio of data packet.

In the present embodiment, the first bluetooth equipment can obtain the RSSI: the first indigo plant of the second bluetooth equipment in the following way Tooth equipment sends third request to the second bluetooth equipment, and third request is used for the RSSI of the second bluetooth equipment of request.Second Bluetooth equipment can detect RSSI, and RSSI carrying is sent to the first bluetooth equipment in the response requested according to third.First is blue Tooth equipment receives the response for the third request that the second bluetooth equipment is sent, and obtains the second bluetooth equipment from the response that third is requested RSSI.
