The D2DDiscovery signals of corresponding UE are received on running time-frequency resource.
It is found D2Ds of the UE according to the special controlled entity configurations of D2D in the special control point management regions of D2D
Discovery signal relevant configuration informations send D2D Discovery signals, and the discovery UE in the management region is special according to D2D
The D2D Discovery signals configured with controlled entity receive the D2D Discovery signals that configuration information receives other UE.When
It was found that UE find to it is desired be found UE when, optionally, D2D connections can be initiated and establish process, to pass through the D2D of foundation
It connects and is found UE and carry out D2D communications.
Referring to Fig. 6, the assigning process that the resource used is communicated for D2D provided in an embodiment of the present invention connects foundation with D2D
Flow diagram.Following flow finds that UE1 meets D2D connections and establishes with aforementioned UE2 by D2D Discovery discovery procedures
Condition is established for process to initiating D2D connections and is described, as shown, the flow may include：
Step 601：UE2（It is expected that carrying out the discovery UE of D2D communication）It was found by D2D Discovery
Cheng Faxian UE1（It is found UE）Meet D2D connection set up the condition, then sending D2D connections to the special controlled entities of D2D establishes request
Message is established D2D with UE1 with request and is connect.
Specifically, UE2 has found that UE1 meets D2D connection set up the condition by D2D Discovery discovery procedures, then pass through
The eNB2 of UE2 ownership（ENB2 is not shown）D2D connections, which are sent, to the special controlled entities of D2D establishes request message.D2D connects
The mark established in request message and can carry UE2 is connect, can also further be carried related to the progress business of D2D transmission is needed
Information, such as type of service, QoS（Quality of Service, service quality）Deng.Wherein, meet D2D connections foundation
Condition refers to by D2D Discovery discovery procedures, UE2（It was found that UE）It was found that UE1（It is found UE）D2D
The mark of its interested business is carried in Discovery signals, and the radio link conditions between UE2 and UE1 meet D2D
Transmission demand.
Step 602：The special controlled entities of D2D determine whether that D2D connections are established.If it is allowed, then executing follow-up step
Rapid 603, request is established in the D2D connections for otherwise refusing UE2.
Specifically, the special controlled entities of D2D can be according to the UE that currently establish D2D connections（UE2 and UE1）Mark, D2D
It connects the business information to be transmitted, need to establish the UE of D2D connections（UE2 and UE1）Resource situation under the eNB of ownership（It is limited to
The case where D2D connections and D2N connection multiplexing same assets）, D2D connection private resource service conditions（D2D connections are connected with D2N
The case where using different resource）, it is determined whether allow D2D connections to establish.
Step 603：The special controlled entities of D2D distribute D2D communications after determining that permission D2D connections are established, for D2D UE to be made
Resource.
Specifically, the special controlled entities of D2D are responsible for D2D communication resource distributions.It is used with D2D links and D2N links independent
Resource for, the special controlled entities of D2D remaining can be provided according to type of service that UE2 to be transmitted, current D2D connections are available
The duplex mode of the duplex mode and the home cells UE2 of the home cells UE1 in source, D2D groups（It also needs to examine if it is TDD system
Consider TDD UL（Uplink）/DL（Downlink）Configuration）Determine what sending and receiving UEs and transmitting-receiving of the interior UE of D2D groups in each subframe were used
The information such as resource.
Step 604：After the special controlled entity distribution D2D communication resources of D2D, by resource allocation conditions notice UE1 ownership
The base station of base station and UE2 ownership, the base station of UE2 ownership can be according to the scheduling timing relationships of the home cells UE2 by the resource of distribution
Notify to UE2, the base station of UE1 ownership can according to the scheduling timing relationship of the home cells UE1 by the resource notification of distribution to UE1.
For example, when dispatching UE2, the resource for distributing to UE2 is sent to by UE2 by downlink subframe, when dispatching UE1, passes through downlink
The resource for distributing to UE1 is sent to UE1 by subframe.
The D2D for distributing to UE communicates the resource used, can be only used for the D2D communications after this D2D connection is established, next time
After D2D connections are established, need to redistribute the resource that D2D communications use.The resource that uses of D2D communications for distributing to UE can also
Whithin a period of time effectively（The length of the period can be set by the special controlled entities of D2D）, within this time, UE is carried out
D2D communications can use the resource.
Step 605：The special controlled entities of D2D send connection establishment response after carrying out resource allocation, to UE1 and UE2 and disappear
Breath connects foundation completion to indicate UE2 with UE1D2D.It is sent in the connection establishment response message of UE1 and may include：As communication
The mark of the UE2 of opposite end, D2D RB（D2D radio bearers）The contents such as relevant information；Being sent to the connection of UE2, establish in message can
Including：The mark of UE1 as Correspondent Node, D2D RB（D2D radio bearers）The contents such as relevant information.In addition, D2D connections are built
Vertical response message can also carry the D2D distributed in step 603 and transmit the resource used.Certainly, D2D connection establishment responses message
The resource used with D2D transmission can also respectively be sent by two message.
In above-mentioned flow, the special controlled entities of D2D determine whether that the step of D2D connections are established is optional step, that is,
The special controlled entities of D2D can directly be that UE1 and UE2 distributes D2D communications after request message is established in the D2D connections for receiving UE2
The resource used, after UE receives the instruction information for the resource that D2D communications use, you can to confirm that D2D connections are successfully established.
Further, if there is D2D groups will be added in UE, it is expected that carry out D2D communications with the member in D2D groups, then it can be to D2D
D2D connections are established in the request of special controlled entity, and D2D connections establish that process is similar with above-mentioned flow, and this will not be detailed here.
Further, if there is UE will leave D2D groups, i.e., D2D communications no longer are carried out with the member in D2D groups, then it can be to
The special controlled entities of D2D send D2D connection release request message.For example above-mentioned UE2 will discharge the D2D connections between UE1, then
Send D2D connection release request message to the special controlled entities of D2D, wherein carry the mark of UE1, with request release and UE1 it
Between D2D connections；After the special controlled entities of D2D receive the D2D connection release request message, connect according to the D2D of release is asked
Row respective handling is tapped into, for example deletes the D2D link informations locally preserved, and sends D2D connection release requests to UE1 and disappears
Breath, wherein carrying the mark of UE2, instruction release is connect with the D2D of UE2；After UE1 receives the D2D connection release request message, release
The D2D put between UE2 is connect.
Further, if to change D2D RB in D2D groups（Radio Bearer, radio bearer）Deng operation, Ke Yitong
Cross the completion of D2D connection modification processes.For example realize the modification of D2DRB by re-matching D2D connections.
Further, the special controlled entities of D2D can also initiate D2D Connection Release processes.When the special controlled entity hairs of D2D
There is UE in existing D2D groups（Herein by taking above-mentioned UE2 as an example）It is no longer appropriate for carrying out D2D transmission（For example D2D is resource-constrained or UE is indicated
D2D quality of connection is deteriorated）, then the D2D connections for being no longer appropriate for carrying out D2D transmission can be directed to（Herein with above-mentioned UE2 and UE1 it
Between D2D connections for）, the interior corresponding UE1 of the D2D connections of D2D groups is notified to discharge the D2D with UE2 and connect.
