Description
Technical field
The present invention relates to a kind of Bluetooth connecting method, particularly relate to the side that a kind of bluetooth is remotely connected
Method.
Background technology
From strength to strength, wherein bluetooth has become as a kind of standard configuration to the function of current mobile phone.Between mobile phone
Communication modes be no longer only limitted to GSM/GPRS, bluetooth also play in mobile phone wireless communication mode weight
The role wanted.Bluetooth has communication simple, and transmission speed is very fast, without the advantage of network requirement.But meanwhile,
Bluetooth also has the shortcoming that transmission range is short.
As a example by setting up bluetooth connection by between simple mobile phone, current Bluetooth transmission distance typically can only be at 10M
Within, and due to various interference in reality, its distance can be shorter.But realize bluetooth the most at a distance
It is impossible that equipment connects.
It is therefore desirable for a kind of method that can realize the connection of remote bluetooth can be found.

Detailed description of the invention
Provide present pre-ferred embodiments below in conjunction with the accompanying drawings, to describe technical scheme in detail.
With reference to Fig. 1, the step searching for destination end in the Bluetooth connecting method of the present invention is as follows:
Step 100, using transmitting terminal as present node, and incoming father node list.Now, owing to sending out
Sending end is start node, the most there is not father node, so father node list now is empty.
Step 101, searches for the attachable all nodes of present node, and generates connectable device list,
Attachable for present node all nodes are stored in this connectable device list.
Step 102, removes the node repeated in this connectable device list with father node list.
Step 103, adds access path by present node.
Step 104, has how many child nodes under search present node.
Step 105, all child nodes of cycle criterion present node, if certain height joint of present node
Point is destination end？If so, step 106 is entered；If it is not, enter step 107.
Step 106, finds destination end.
Step 107, searches for the attachable all nodes of present node, and by attachable for present node institute
Node is had to be stored in this connectable device list.
Step 108, using the child node of present node as new present node, and by this connectable device
List is as father node list.
Step 109, starts recursive search according to new present node.
Step 110, it is judged that whether recursive search terminates？If so, step 111 is entered；If it is not, return
Step 101.
Step 111, there is not destination end, deletes the tail of access path in present node and below child node
Portion's node, i.e. present node.
Step 112, does not finds destination end.
With reference to Fig. 2, it is as described below to the step of destination end that transmitting terminal sends connection request:
Step 200, transmitting terminal sends connection request to present node.
Step 201, present node obtains connectivity request message.
Step 202, it is judged that whether present node is destination end, if so, enters step 203；If it is not,
Enter step 204.
Step 203, destination end sends response link information.
Step 204, connection request is sent to the next joint of present node in access path by present node
Point.
Step 205, and returns the next node of present node in access path as new present node
Return step 201.
With reference to Fig. 3, it is as described below to the step of transmitting terminal that destination end sends response link information:
Step 300, destination end sends response link information to present node.
Step 301, present node obtains response link information.
Step 302, it is judged that whether present node is transmitting terminal, if so, enters step 303；If it is not,
Enter step 304.
Step 303, transmitting terminal is set up and is connected with the bluetooth between destination end.
Step 304, response link information is sent in access path upper the one of present node by present node
Individual node.
Step 305, and returns a upper node of present node in access path as new present node
Return step 301.
Below in conjunction with an application example, Bluetooth connecting method of the present invention being described again, wherein bluetooth sets
Standby as a example by the mobile phone with bluetooth module, it is assumed that to need to set up the bluetooth between mobile phone A and mobile phone D
Connecting, concrete implementation mode is as follows:
(1) mobile phone A passes through bluetooth discovery mobile phone D；
In described step (1), mobile phone A is included by the step of bluetooth discovery mobile phone D:
(1-1) mobile phone A finds mobile phone A 1, A2 by search bluetooth equipment ..., An (n is natural number)；
(1-2) list of devices that oneself is searched by mobile phone A as father node is sent to this equipment successively
Sub node equipment A1 in list, A2 ..., An (n is natural number)；
(1-3) device A 1, A2 in list of devices ..., An (n is natural number), after obtaining list, remembers
Record the father node mobile phone A of oneself, simultaneously scan for the equipment that each self energy finds, and the equipment found at these
In exclude the part obtaining before having in list, the part that will repeat is removed, obtain a oneself
Child list, the list of devices that simultaneously oneself searched transmits its that come and searches together with father node
List of devices merges into the list of devices oneself searched, and mobile phone A dynamic in (1-2) before repeating
Make, until finding mobile phone D；
(1-4) path (D) of oneself is fed back by mobile phone D to father node D1, and father node D1 is connecing
After the feedback of child node, oneself is added path (D1-D) and feeds back, by this side to the father node of oneself
Method feeds back to node A always, thus obtains the path of A-......-D.
(2) with mobile phone D, mobile phone A is carried out bluetooth to be connected.
Mobile phone A is carried out the step that bluetooth is connected by described step (2) with mobile phone D including:
(2-1) path of the A-......-D that mobile phone A records according to oneself, by oneself connection request and
Access path is sent to next node mobile phone B；
(2-2) action of mobile phone A during node mobile phone B repeats (2-1)；
(2-3) as above circulate up to mobile phone D；
(2-4) request of mobile phone D response mobile phone A, feeds back to mobile phone by connection response by access path
C；
(2-5) action of mobile phone D during node mobile phone C repeats (2-4)；
(2-6) as above circulate up to mobile phone A；
(2-7) mobile phone A is set up with mobile phone D and is connected.
Although the foregoing describing the detailed description of the invention of the present invention, but those skilled in the art should managing
Solving, these are merely illustrative of, and protection scope of the present invention is defined by the appended claims.This
The technical staff in field, can be to these embodiment party on the premise of without departing substantially from the principle of the present invention and essence
Formula makes various changes or modifications, but these changes and amendment each fall within protection scope of the present invention.
