Description
Technical field
The present invention relates to wireless communication technology field, particularly relate to a kind of method and system reducing the transmission signal radiation of Wearable Bluetooth Low Energy equipment.
Background technology
Along with the development of Bluetooth technology, bluetooth 4.0 agreement starts to support Bluetooth Low Energy (BLE) equipment.Through the industrial circle promotion of several years and development, the electronic equipment based on Bluetooth Low Energy technology gets more and more, and obtains very large popularization with universal in a lot of application.Along with increasing Smartphone device can support bluetooth 4.0 hardware and software protocol stack, the more universal of Bluetooth Low Energy equipment has been provided with solid technical foundation.
Usually can form a piconet (piconet) between Bluetooth Low Energy equipment, inside piconet, have a main equipment (master) to set up bluetooth with one or more respectively from equipment (Slave) be connected.Under normal circumstances, a main equipment can set up bluetooth connection with multiple from equipment simultaneously; And one from equipment only to connect with a main equipment, until this disconnects from the connection of equipment and main equipment.
According to bluetooth 4.0 agreement, between master-slave equipment, need the device discovery procedure, connection establishment process, pairing process and the binding procedure that experience as shown in Figure 1.In the device discovery stage, repeat to send broadcasting packet from equipment according to certain intervals, if main equipment have received this broadcasting packet and interesting inquiry more information, then main equipment can send scan request message, and from equipment meeting feedback scan response message, such main equipment just can obtain further from the more information of equipment.
After principal and subordinate, equipment complete above-mentioned device discovery procedure, connection establishment process, pairing process and binding procedure, the physical channel of foundation just can be used to carry out data communication.Physical channel is split the multiple timeslices for being called as " event " usually.
Described " event " comprises broadcast event and connection event.In a connection event, main equipment can send message to from equipment, can respond the message of main equipment from equipment as required.If main equipment does not send message to from equipment in the time slot at certain event place, then cannot send message to main equipment in this event from equipment.After connection establishment is got up, even if the application program on main equipment does not follow the needs of the peer application communication on equipment, the floor portions of protocol stack and bottom hardware also can drive hardware regularly send message carry out between master-slave equipment " heartbeat " operation: by certain message requiring that in certain hour interval, (maximum 32 seconds) send from device responds main equipment, allow master-slave equipment understand existence each other, guarantee the validity connected.
According to bluetooth 4.0 agreement, the equipment of a Bluetooth Low Energy, four kinds of GAP (GenericAccessProfile) roles can be played the part of: broadcaster (Broadcaster), observer (Observer), from machine (Peripheral) and main frame (Central).
Emerge the increasing Wearable using Bluetooth Low Energy technology in the market.These equipment often one and be worn on the body of people from equipment, be even directly attached on the trunk of human body.The main target of Bluetooth Low Energy technology is energy-conservation, so in real work, the transmitted power of this kind equipment is very little (according to bluetooth 4.0 agreement, maximum transmitting power is+10dBm, and minimum is-20dBm).Although transmitting power is compared to WiFi technology and the non-low power consuming devices of bluetooth, and Bluetooth Low Energy equipment has had and significantly reduces.But in some scenarios, the radiation that bluetooth equipment brings still annoyings most of user.
In prior art, one support the main equipment (such as a smart mobile phone) of Bluetooth Low Energy technology and a support Bluetooth Low Energy technology between equipment (such as one can be close to human body skin continuous human body body temperature and report that body temperature exceedes the clinical thermometer of a certain threshold value), establish connection.Because clinical thermometer is close on skin, so user can wish this clinical thermometer only when body temperature exceedes a certain threshold value, the warning message just sending less data amount processes to mobile phone; And after sending warning message, just can stop immediately sending any data, thus reduce the transmission signal radiation of this equipment.
And this type of is after connecting from the Normal practice of equipment in the market, bottom software, hardware can respond main equipment according to certain hour interval and send " heartbeat packet ", normal to ensure with the connection of main equipment.If the connection between master and slave equipment is disconnected, then needs to continue to send broadcast packet from equipment and main equipment can be found oneself and again connect, discovery as shown in Figure 1, connection procedure.For these reasons, this clinical thermometer still constantly can send data when not having warning message to transmit, thus produces radiation constantly, and this just has the expectation of refuting in user, causes the worry of user.
