Below in conjunction with concrete application scenarios the present invention is introduced.Wherein, the equipment of initiating the foundation of D2D network can have user interface, also can not have user interface.
The method that the embodiment of the invention provides a kind of D2D network to set up has been set up under the situation about being connected with a certain AP at two WiFi terminals, and the user sets up the mechanism of D2D network between two WiFi terminals by the method for button.This mechanism wants desire to set up in two terminals of D2D network, has at least a terminal that abundant user interface can be provided, and for example display screen makes the user can select to set up with it target terminal of D2D network.
Concrete, as shown in Figure 3, may further comprise the steps:
Step s301, the select target terminal equipment.
The process of setting up of D2D network can be initiated by the equipment STA1 that enriching user interface can be provided in two WiFi terminals between two WiFi terminals, and we can be called initiating equipment.The user at first selects desire to set up the target terminal equipment STA2 of D2D network at initiating equipment by user interface.
Step s302 sends the D2D network by AP (Access point, access point) to target terminal equipment and sets up request message.
After target terminal equipment is selected, the user presses the D2D network that is positioned on the initiating equipment and sets up configuration button, initiating equipment STA1 sends the D2D network to selected target terminal equipment STA2 and sets up request message, carries the information of consulting MASTER (main equipment) in the D2D network in this request message; Request message at first sends to the AP that is connected with initiating equipment by the communication link of setting up in advance between initiating equipment and the AP, AP according to the destination address in this message and and target terminal equipment between the communication link set up in advance forwards is arrived target terminal equipment STA2.
Step s303, target terminal equipment sends response message by AP to initiating equipment.
After the D2D network that target terminal equipment STA2 receives initiating equipment STA1 is set up request message, selectively pointed out device request to set up D2D in modes such as sound, indicator light, displaying information on screen and connected to the target terminal equipment user.
When destination end user finds to have device request D2D to connect, the D2D network of pressing on the equipment if this user agrees this D2D connection request is set up configuration button, target device will be set up response message to initiating equipment STA1 transmission D2D network this moment, carry the information of consulting MASTER equipment in the D2D network in this message.
This response message at first sends to the AP that is connected with target terminal equipment by target terminal equipment with communication link between the AP, AP according to the target address information in this response message and and initiating equipment STA1 between communication link this response message is sent to initiating equipment STA1; Execution in step s304.
Target terminal equipment STA2 receive set up request message from the D2D network of STA1 equipment after, if the target device user fails to press the button in official hour, then target device selectively sends the D2D network that comprises refusal information to initiating equipment and sets up response message, does not perhaps respond.
If initiating equipment STA1 does not receive the D2D network of target device and sets up response message in official hour, perhaps receive the message that refusal D2D connects, then can resend the D2D network and set up request message.
If target device has successively received two different D2D networks and set up request message before pressing the button, then this time wps configuration can't be finished, and the user need initiate the process of setting up of D2D network again.Target terminal can not respond this request message, the perhaps response message of response reject D2D connection, and the reason that feedback is refused in response message.
Set up in the reciprocal process of request, response message at above-mentioned D2D network, two terminals can be used for determining by which terminal to be the Master of D2D network by carry the negotiation information of Master in message.In addition, before the message interaction process of carrying out foregoing description, two equipment STA1 have set up with AP in advance with STA2 and have been connected, so above-mentioned D2D network is set up can realizing by AP alternately of request, response message.
Setting up the D2D network between the step s304, initiating equipment and target terminal equipment is connected.
Receiving after acceptance that target device STA2 returns sets up the response message that D2D connects at initiating equipment STA1, also just determined the terminal equipment as D2D network master (Master) simultaneously, for example is STA1.Thereafter, WiFi easy configuration process (WSC) be initiated and be finished to two terminals can based on the authentication protocol (EAP) of expansion, MASTER is to method, apparatus is sent the D2D network configuration data in the D2D network, configuration data comprises one or more in network identity, channel logo, the key information, uses configuration data to set up the environment that carries out the D2D communication between local initiating equipment and the target terminal equipment; This process is existing definition in present WiFi relevant criterion, and different is, the message interaction process at this place all is to connect the road with the communication of AP foundation in advance by two terminals to realize.If in the predefined time, do not receive the response message of the target terminal equipment of described access point forwarding to described request message, the response message that perhaps receives is a refuse information, then send network to described target terminal equipment again and set up request message, up to reaching predetermined transmission number of times or preset time.
Set up by said process after the D2D network connects having set up two WiFi terminals that are connected with same AP, the communication between these two terminals not only can have been undertaken but also can connect by D2D realizing by the AP communication link.Look quality and two demands that terminal moves of the Connection Service that AP provides, two terminals can determine whether communication path is switched to the D2D communication link from the AP communication link through consultation, as for how finishing two switchings of terminal between two communication links, at present existing a plurality of standards have provided implementation separately, do not repeat them here.In addition, this handoff procedure also can initiatively have been finished the terminal initiation handoff request message trigger that the D2D network is set up to two according to the situation of self by AP.
By the method that adopts the embodiment of the invention to provide, utilize button to trigger and set up message by the communication link transmission D2D network of setting up in advance between terminal equipment and the AP, the D2D network of setting up between the terminal equipment connects, and the user is simple to operate, is user-friendly to.
