D2D终端的连接建立方法、装置及系统 D2D connection terminal is established method, apparatus and system for

技术领域 FIELD

[0001] 本发明涉及通信技术,具体涉及一种设备到设备(Device to Device,D2D)终端的连接建立方法、装置及系统。 [0001] The present invention relates to communication technology, particularly relates to an apparatus device (Device to Device, D2D) connection terminal is established methods, apparatus and systems.

背景技术 Background technique

[0002] 在小区网络中,用户设备(User Equipment,UE)要与其他用户设备进行通信时,通常需要通过基站进行集中式控制,例如在LTE网络中的演进基站(Evolved Node B,eNB)控制呼叫双方的UE之间的呼叫建立等信号连接过程。 [0002] In the cell network, a user equipment (User Equipment, UE) To communicate with other user devices, typically require centralized control by the base station, for example, in an LTE network, an evolved base station (Evolved Node B, eNB) control call call setup procedure such as signal connections between the two sides of the UE. 用户间通信链接经过基站协调控制的好处在于,由于基站可以集中管理小区内无线资源的使用,从而使得无线资源得到合理有效的分配,同时可以很好地避免用户间无线干扰。 A communication link between users via the base station coordinated control advantage is that, due to the centralized management of the base station can use the radio resources within the cell, so that the radio resources will be effective distribution, while good to avoid radio interference between users. 但是,在两个用户设备距离比较近的情况下,如果仍通过基站进行通信,则会带来无线资源的浪费。 However, two user equipment is relatively close distance, if still communicate through the base station, it will bring the waste of radio resources. 相比于小区模式的通信方式,D2D通信在传输同样的数据量的情况下,可以节省一半的无线资源。 Compared to cell communication mode, the D2D communication without the same amount of data transmission, half of the radio resources can be saved. D2D通信是在终端之间进行直接通信,因此D2D通信的终端之间传输的信息无需经过基站。 D2D communication is direct communication between terminals, so D2D communication between the terminal for transmission of information without going through a base station.

[0003] 在现有的无线网络中,当处于空闲(idle)模式的UE接收到网络侧发送的寻呼消息(paging)时,首先需要经过随机接入(Random Access,RA)过程,获取上行同步时间提前量(Timing Advance,TA)值和/或合适的发射功率值,才能与网络建立连接,进而传输用户数据。 [0003] In existing wireless networks, when the UE is in an idle (IDLE) mode receives a paging message (Paging) sent by the network, first go through a random access (Random Access, RA) procedure to acquire uplink synchronizing the timing advance (Timing advance, TA) value and / or a suitable transmission power value, to establish a connection with the network, and then transmit user data.

[0004]图1中示出了现有技术中UE与eNB连接建立的信令图。 In [0004] FIG. 1 shows a signaling diagram of a prior art connection establishment in the UE and eNB.

[0005] 步骤11、第一UE发送前导码(Preamble)到eNB; [0005] In step 11, the UE first transmits a preamble (a Preamble) to the eNB;

[0006]步骤 12、eNB返回随机接入响应消息(Random Access response message ,RAresponse message)到第一UE,该响应消息包含上行同步TA值和合适的发射功率; [0006] Step 12, eNB returns a random access response message (Random Access response message, RAresponse message) to the first UE, where the response message including an uplink synchronization value TA and a suitable transmission power;

[0007] 步骤13、第一UE以上述发射功率发送RRC连接建立请求消息到eNB; [0007] Step 13, the first UE sends an RRC connection establishment request message to the eNB to said transmit power;

[0008]步骤 14、eNB返回冲突解决消息(content1n resolut1n)到第一UE; [0008] Step 14, eNB returns resolution message (content1n resolut1n) to the UE first;

[0009] 步骤15、eNB返回RRC连接配置参数到第一UE ; [0009] Step 15, eNB sends an RRC connection configuration parameters to the UE first;

[0010] 步骤16、第一UE发送RRC连接建立完成消息到eNB。 [0010] Step 16, the first UE sends an RRC connection setup complete message to the eNB.

[0011] 然而对于距离较近的D2D的UE,UE之间具有近乎相同的TA和/或发射功率,因此当eNB呼叫被叫方第二UE进行D2D的数据传输时,如果基站再按照图1所示的通信方法与第二UE建立连接,会导致被叫方第二UE执行不必要的随机接入过程,因而增加了连接建立的时延。 [0011] However, for the short distance of the D2D UE, having approximately the same TA and / or between the UE transmit power, so that when the second eNB UE party calls a called the D2D data transmission, then if the base station 1 according to FIG. the communication method illustrated in the second UE to establish a connection, the called party can result in an unnecessary second UE performs a random access procedure, thereby increasing the latency of the connection establishment.

具体实施方式 Detailed ways

[0032] 下面对D2D终端的连接建立方法、系统和装置进行详细说明。 [0032] The following D2D connection terminal is established methods, systems and apparatus described in detail.

[0033]图2示出了根据本发明一个实施例的D2D终端的连接建立方法的示意性流程图。 [0033] FIG. 2 shows a schematic flowchart of method for establishing a D2D connection terminal according to one embodiment of the present invention.

[0034] 参见图2可见,主叫用户设备第一UE要与被叫用户设备第二UE之间建立D2D连接,执行以下步骤: [0034] Referring to Figure 2, a first calling user equipment UE is to establish a D2D connection, perform the following steps between the called UE and a second user equipment:

[0035] 步骤201:第一用户设备UE向基站发送前导码preamble; [0035] Step 201: a UE first transmits a preamble to a base station preamble;

[0036] 步骤202:基站在接收到第一UE发送的preamble之后向第一UE发送随机接入响应RA response消息,由此,第一UE接收所述基站响应于所述preamble所发送的随机接入响应消息。 [0036] Step 202: the base station transmits the random access preamble transmitted after receiving the first response to the first UE UE RA response message, whereby the base station receives the first UE in response to the random access preamble transmitted the response message. 其中,在该消息中可以携带用于第一UE的时间提前量TA值和/或发射功率值,以供第一 UE接入基站使用。 Wherein, in the message may carry the first UE for the timing advance TA value and / or the transmission power value for the first UE to access the base station use.

[0037] 步骤203:第一UE向所述基站发送第二UE标识,所述第二UE是第一UE的D2D通信目标,也即第一UE要与第二UE建立D2D通信。 [0037] Step 203: UE sends a first base station to the second UE identity, the second UE is a UE, the target first D2D communication, i.e. the first UE to establish D2D communication with the second UE. 第二UE标识例如可以是第二UE的临时移动用户标识(S-TMSI)或其他的标识。 The second UE identity, for example, may be a temporary mobile subscriber identity (S-TMSI), or other identification of a second UE. 第一UE可以通过检测第二UE来获取第二UE的标识,也可以使用第二UE的用户号码。 The first UE may obtain an identifier of the second UE by detecting the second UE, the subscriber number may be used for the second UE. 第一UE可以向基站发送RRC连接建立请求消息,所述RRC连接建立请求消息中携带所述第二UE标识。 The first base station may send a UE RRC connection request message, the RRC connection establishment request message carries the second UE identity.

[0038] 步骤204:基站响应于所述第二UE标识将第一UE的D2D链路配置参数和RRC连接配置参数发送给第一UE,由此第一UE接收基站响应于所述第二UE标识所返回的第一UE的D2D链路配置参数和RRC连接配置参数,其中该D2D链路配置参数用于第一UE与第二UE之间的D2D连接。 [0038] Step 204: The base station in response to the second UE identifies the D2D link configuration parameters of the first UE and the RRC connection configuration parameters to the first UE, whereby the UE receives a first base station in response to the second UE D2D link configuration parameters of the first UE identity and returned RRC connection configuration parameters, wherein the D2D link configuration parameters for a first UE D2D connection between the second UE. 具体而言,D2D链路配置参数和RRC连接配置参数包括分组数据汇聚协议(PDCP)层、无线链路控制(RLC)层、媒体接入控制(MAC)层,物理(PHY)层的各层的静态或半静态的参数配置。 Specifically, the D2D link configuration parameters configuration parameters and the RRC connection comprises a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a media access control (MAC) layer, a physical (PHY) layer of the layers static or semi-static configuration parameters. 在此,基站可以向第一UE发送RRC连接建立消息,在RRC连接建立消息中携带基站响应于第二UE标识所返回的第一UE的D2D链路配置参数。 Here, the base station may establish a connection to the first UE transmits RRC message, the RRC connection establishment D2D link configuration parameters of the first UE to the second UE identity carried in the message returned in response to the base station. 也可能的是,基站通过D2D小区无线网络临时标识(D2D-C-RNTI)加扰物理下行控制信道(PDCCH)向第一UE发送第一UE的D2D链路配置参数和RRC连接配置参数的调度信息,从而第一UE利用D2D-C-RNTI解扰物理下行控制信道PDCCH获取基站发送的第一UE的D2D链路配置参数和RRC连接配置参数的调度信息,并进一步根据所述调度信息获取所述第一UE的D2D链路配置参数和RRC连接配置参数。 It is also possible that the base station over the D2D cell radio network temporary identity (D2D-C-RNTI) scrambled physical downlink control channel (PDCCH) is connected to a first configuration parameter scheduling UE D2D link configuration parameters of the UE and transmitting a first RRC information to the first UE using the D2D-C-RNTI descrambling a PDCCH acquired first UE D2D link configuration parameters and scheduling information of RRC connection configuration parameters transmitted from the base station, and further obtain the information according to the schedule said first D2D link configuration parameters of the UE and an RRC connection configuration parameters. 需要说明的是,在利用D2D-C-RNTI来传送调度信息的情况下,第一UE需要首先获取基站分配的D2D-C-RNTI。 Incidentally, in the case of using D2D-C-RNTI to transmit the scheduling information, the UE needs to first obtain a first D2D-C-RNTI assigned to the base station. 为此,第一UE可以通过基站发送的RA response消息或content 1nresolut1n消息获取D2D-C-RNTI,其中所述D2D-C-RNTI携带在上述RA response消息或content1n resolut1n消息中,或者第一UE也可以接收基站直接发送的D2D-C-RNTI分配消息。 To this end, a first UE RA response message may be sent through the base station or the message acquiring content 1nresolut1n D2D-C-RNTI, wherein the D2D-C-RNTI carried in the above-mentioned RA response message or messages content1n resolut1n, or the first UE also the base station may receive D2D-C-RNTI allocation message is sent directly.

[0039] 步骤205:基站向第二UE发送寻呼消息,该寻呼消息用于指示第二UE的D2D链路配置参数和RRC连接配置参数,并且该寻呼消息还可以携带用于第二UE的时间提前量TA值和/或发射功率值,或者可以指示第一UE和第二UE共享时间提前量TA值和/或发射功率值,使得第二UE将与第一UE共享的TA值和/或发射功率值作为第二UE的TA值和/或发射功率值,以将第二UE接入基站。 [0039] Step 205: the base station sends a paging message to the second UE, the paging message for the D2D link configuration parameters of the second indication and the UE RRC connection configuration parameters, and the paging message may further carry a second UE timing advance TA value and / or transmission power value, or may indicate the first and second UE sharing the timing advance TA value and / or transmission power value such that the TA value shared with the first UE to the second UE and / or the transmit power value as a second value TA of the UE and / or the transmit power value, the second UE to access the base station. 另外,该寻呼消息还包含第二UE的S-TMS1、为第二UE分配的小区无线网络临时标识(Cell-Rad1 Network Temporary Identity,C-RNTI)。 Further, the paging message further includes a second UE, S-TMS1, the second UE assigned to a cell radio network temporary identity (Cell-Rad1 Network Temporary Identity, C-RNTI). 由此,第二UE相应地从基站接收来自基站的寻呼消息,并基于该寻呼消息获取第二UE的D2D链路配置参数和RRC连接配置参数,其中该D2D链路配置参数用于第二UE与第一UE之间的D2D连接。 Accordingly, the second UE receives a paging message from a respective base station from the base station, and acquires the second D2D link configuration parameters of the UE and the RRC connection configuration parameters based on the paging message, wherein the configuration parameters for the D2D link section two UE D2D connection between the first UE. 第二UE的D2D链路配置参数和RRC连接配置参数可以携带在基站向第二UE发送的寻呼消息中,也可能的是,在第二UE从基站接收到寻呼消息并确定允许进行D2D通信后,发送paging响应消息,确认可以进行D2D通信,在此之后基站才通过另外的消息将第二UE的D2D链路配置参数和RRC连接配置参数发送给第二UE。 D2D link configuration parameters of the second UE and the RRC connection configuration parameters may be carried in a paging message sent by the base station to the second UE, it is also possible that the second UE in the paging message received from the base station and determines to allow D2D after communication, sending paging response message, D2D communication may be confirmed, the base station only after the D2D link and the second UE RRC connection configuration parameters configuration parameters to the UE through the second further message. 另外还可能的是,基站通过D2D-C-RNTI加扰物理下行控制信道(PDCCH)向第二UE发送第二UE的D2D链路配置参数和RRC连接配置参数的调度信息,从而第二 UE利用D2D-C-RNTI解扰物理下行控制信道PDCCH获取基站发送的第二UE的D2D链路配置参数和RRC连接配置参数的调度信息,并进一步根据所述调度信息获取所述第二UE的D2D链路配置参数和RRC连接配置参数。 Further it is also possible that the base station scrambling physical downlink control channel (PDCCH) scheduling information is connected to the second UE configuration parameters configuration parameters of the D2D link sent by the second UE and the RRC D2D-C-RNTI, so that the second UE using D2D-C-RNTI descrambling a PDCCH transmitted from the base station acquired D2D link configuration parameters of the second UE RRC connection configuration parameters and scheduling information, and further obtains the scheduling information according to the second UE D2D chain RRC connection path configuration parameters and configuration parameters. 第二UE同样可以利用D2D-C-RNTI来获取时间提前量TA值和/或发射功率值。 The second UE can also use D2D-C-RNTI to get the timing advance TA value and / or transmit power values. 需要说明的是,在利用D2D-C-RNTI来传送调度信息的情况下,第二UE需要首先获取基站分配的D2D-C-RNTI ο为此,第二UE接收基站发送的D2D-C-RNTI分配消息,该D2D-C-RNTI分配消息可以被携带在基站向第二UE发送的上述寻呼消息中,也可以通过单独的消息发送。 Incidentally, in the case of using D2D-C-RNTI transmitted scheduling information, the UE needs to first obtain a second D2D-C-RNTI assigned to the base station ο For this purpose, D2D-C-RNTI the base station sends a second UE receives allocation message, the D2D-C-RNTI allocation message may be carried in said paging message transmitted in the base station to the second UE, may be sent in a separate message.

[0040] 基站向第二UE发送寻呼消息之前还可以包括基站根据第二UE的C-RNTI为第二UE分配上行链路许可UL grant,UL grant既可以包含在所述基站发送的寻呼消息中被发送到第二UE,也可以作为单独的消息被所述基站发送到第二UE。 [0040] Before the second base station sends a paging message to the UE may further include a base station according to the second C-RNTI of the UE is the second UE uplink grant allocated UL grant, UL grant can include both paging transmitters at the base station a second message is sent to the UE, or as a separate message is sent by the base station to the second UE.

[0041] 步骤206:第一UE与所述第二UE建立D2D连接,并分别基于各自RRC连接配置参数完成与基站的RRC连接建立。 [0041] Step 206: UE establishes a first connection with the second UE D2D, respectively based on the respective configuration parameters for RRC connection complete the RRC connection establishment the base station. 由于通过步骤204,第一UE获得了其D2D链路配置参数,而通过步骤205,第二UE获得了其D2D链路配置参数,因此第一UE和第二UE可以建立彼此间的D2D连接。 Since in step 204, the UE obtains its first D2D link configuration parameters, in step 205, the UE obtains its second D2D link configuration parameters, the first and second UE D2D connection may be established between them. 在连接建立之后,第一UE和第二UE可以分别向基站发送RRC连接建立完成消息以及D2D连接配置完成消息。 After the connection is established, the first and second UE may be transmitted RRC connection setup complete message to the base station and the D2D connection reconfiguration complete message.

[0042] 在本实施例中,第二UE的TA值和/或发射功率值可以是与第一UE共享的TA值和/或发射功率值。 [0042] embodiment, TA value of the second UE, and / or transmit power values ​​in the present embodiment may be shared with the first UE and the TA value / or transmit power values. 可以有多种方式来确定第一UE是否与第二UE共享TA值和/或发射功率值。 There are several ways to determine whether the first UE share the TA value and / or transmission power value and the second UE. 一种方式是,在步骤201之前,第一UE检测第二UE来获取第一UE与第二UE之间的路径损耗或距离,还获取第二UE标识,第一UE根据所述路径损耗或距离确定第二UE能够与第一UE共享TA值和/或发射功率值。 One way is, prior to step 201, a first UE UE acquires a second detection path loss or distance between the first UE and the second UE, further obtaining a second UE identity, the first UE according to the path loss or determining a second distance value TA UE can share and / or transmission power value and the first UE. 此时,第一UE可以通过所述RRC连接建立请求消息携带指示第一UE和第二UE共享时间提前量TA值和/或发射功率值的指示信息以及第二UE标识发送给基站,使得基站能够将共享的TA值和/或发射功率值发送给第二UE。 In this case, the first UE may request establishment message carries an indication of the first and second UE sharing information indicating timing advance TA value and / or transmission power value and the second UE identity to the base station via the RRC connection, so that the base station TA value can be shared and / or the transmission power value is sent to the second UE. 另一种方式是,在步骤201之前,第一UE检测第二UE来获取第一UE与第二UE之间的路径损耗或距离,还获取第二UE标识。 Another way is, prior to step 201, a first UE UE acquires a second detection path loss or distance between the first UE and the second UE, further obtaining a second UE identity. 随后,第一UE向基站报告所述路径损耗或距离以及第二UE标识,以供基站确定第二UE是否能够与第一UE共享TA值和/或发射功率值。 Subsequently, the path loss and the second distance or the first UE identity UE reports to the base station, the base station for determining whether the second UE can share the TA value and / or transmission power value and the first UE. 当基站确定第二UE能够与第一UE共享TA值和/或发射功率值时,基站将共享的TA值和/或发射功率值发送给第二UE。 When the base station can be determined and / or transmission power value and a second share of the first UE UE TA value, TA value the shared base station and / or the transmission power value is sent to the second UE.

[0043] 在本实施例中,当第一UE和第二UE通过基站为其分配的D2D-C-RNTI侦听PDCCH来获取调度信息,并且根据所述调度信息接收用于第一UE和第二UE的RRC连接配置参数、D2D链路配置参数、以及用于第二UE的TA值和/或发射功率值信息的一项或多项时,使用D2D-C-RNTI进行HXXH的监听和发送的方法具体如下: [0043] In the present embodiment, when the first and second UE assigned by the base station D2D-C-RNTI to get the listener PDCCH scheduling information, and UE according to the first and second scheduling information for receiving two UE RRC connection configuration parameters, the D2D link configuration parameters, and for monitoring and transmitting the second UE TA value and / or the transmission power value of one or more information using the D2D-C-RNTI for the HXXH specific methods are as follows:

[0044] 第一UE和第二UE都用D2D-C-RNTI进行监听,基站使用D2D-C-RNTI发送PDCCH,PDCCH中增加新的如下指示信息: [0044] The first and second UE are performed with monitor D2D-C-RNTI, the base station transmits the PDCCH using the D2D-C-RNTI, the PDCCH as adding new instructions:

[0045] 00表示两个UE都需要从基站接收下行DL-SCH资源; [0045] 00 represents two UE needs to receive both downlink resource DL-SCH from a base station;

[0046] 1表示Ud链路的主UE发送,辅UE监听; [0046] Ud 1 represents the main transmission link UE, the UE monitors the secondary;

[0047] OI表示Ud链路的主UE接收,辅UE发送; [0047] OI Ud represents the main link received by the UE, the UE transmits the secondary;

[0048] 11预留域表示两个UE都需要向基站发送上行UL-SCH的资源信息,可以将资源分为两部分分别给两个UE使用)。 [0048] Reserved field 11 represents two UE is required to send the uplink UL-SCH resource information to the base station, the resource can be divided into two parts respectively to the two used by the UE).

[0049]以上仅以两个UE为例,如果UE数量超过两个,则可以使用更多的比特信息指示各个UE的收发操作。 [0049] The two or more UE only an example, if the number of UE than two, more bits may be used transceiving operation information indicating each UE. 即,基站使用D2D-C-RNTI加扰发送的D2D UE的TOCCH调度信息中包含下列信息: That is, the base station uses the scheduling information TOCCH D2D D2D-C-RNTI scrambled transmission of the UE includes the following information:

[0050] 各个UE在当前调度的时间单元内的收发状态指示信息; [0050] each UE information indicating the state of the transceiver unit of time currently scheduled;

[0051] 各个UE的收发状态指示信息可以通过不同位置的比特进行指示,各个UE所对应的指示信息中的位置信息可以通过高层信令预先配置。 [0051] each UE transceiver status indication information may be indicated by a different bit position, the position indication information corresponding to each UE can be pre-configured by higher layer signaling.

[0052] 在本实施例中,通过基站分别为第一UE和第二UE发送它们各自的D2D链路配置参数。 [0052] In the present embodiment, the base station through the first and second UE transmit their respective D2D link configuration parameters, respectively. 可以看出,在第一UE与第二UE建立D2D通信过程中,仅需要第一UE与基站之间进行随机接入过程,第二UE与基站不必重复执行随机接入,从而降低了D2D连接建立的时延。 As can be seen, the D2D communication establishing process of the first UE and the second UE, the first UE only needs to perform random access procedure between the base station and the second base station and the UE a random access operation is not required, thereby reducing the D2D connection establish latency. 另外,因为S-TMSI在TA范围内是唯一的,在基站范围内也是唯一的,因此在基站寻呼第二UE的过程中不需要由基站通知移动管理实体(MME)执行其将执行对于第二UE的寻呼,这样就避免了寻呼过程对于核心网的影响,因而更进一步地降低了D2D连接建立的时延。 Further, since the S-TMSI is unique, it is unique, so the base station need not be informed within the range of a base station in the paging process of the second UE by the base station the mobility management entity (MME) performs it will perform the TA range in respect of two UE paging, thus avoiding the impact of the paging process for the core network, thus further reducing the latency D2D connection establishment. 但是本发明并不限定基站是否通过MME执行寻呼。 However, the present invention is not limited to whether the base station through the MME performs paging.

[0053] 另外在通信过程中,第一UE或第二UE可以定期或事件触发地检测第一UE与第二UE之间的路径损耗或距离,在第一UE和第二UE与网络建立连接后,后续基站可以单独维护第一UE和第二UE的TA更新,即单独向第一UE和第二UE发送TA command命令。 [0053] Further, in the communication process, the first or the second UE may periodically or event trigger detected path loss or distance between the first UE and the second UE, to establish a connection with the network in the first and second UE after subsequent base station may maintain a separate first and second UE updates the TA, i.e. TA command transmitted command to the first and second UE individually. 也可以根据UE定时上报或事件触发上报的距离信息决定使用一个TA command命令进行更新,如果使用一个TA command,那么第一UE和第二UE都统一使用点到点小区无线网路临时标识(D2D-C-RNTI)获取TA command的调度信息,然后根据获取的TA command进行更新。 It can also be regularly report or event triggering reporting of information from the command decided to use a TA command is updated according to UE, if you use a TA command, then the first and second UE are unified cell using point to point wireless network temporary identity (D2D -C-RNTI) TA command for schedule information is then updated according to the acquired TA command.

[0054]图3示出了根据本发明另一个实施例的D2D终端的连接建立方法的示意性流程图。 [0054] FIG. 3 shows a schematic flowchart of a method for establishing a D2D connection terminal according to another embodiment of the present invention.

[0055] 参见图3可见,主叫用户设备第一UE要与被叫用户设备第二UE之间建立D2D连接,执行以下步骤: [0055] Referring to Figure 3, the calling user equipment UE is to establish a first D2D connection, perform the following steps between the called UE and a second user equipment:

[0056] 步骤301:第一用户设备UE向基站发送前导码preamble; [0056] Step 301: a UE first transmits a preamble to a base station preamble;

[0057] 步骤302:基站在接收到第一UE发送的preamble之后向第一UE发送随机接入响应RA response消息,由此,第一UE接收所述基站响应于所述preamble所发送的随机接入响应消息。 [0057] Step 302: the base station transmits the random access preamble transmitted after receiving the first response to the first UE UE RA response message, whereby the base station receives the first UE in response to the random access preamble transmitted the response message. 其中,在该消息中可以携带用于第一UE的时间提前量TA值和/或发射功率值,以供第一 UE接入基站使用。 Wherein, in the message may carry the first UE for the timing advance TA value and / or the transmission power value for the first UE to access the base station use.

[0058] 步骤303:第一UE向所述基站发送第二UE标识,所述第二UE是第一UE的D2D通信目标,也即第一UE要与第二UE建立D2D通信。 [0058] Step 303: UE sends a first base station to the second UE identity, the second UE is a UE, the target first D2D communication, i.e. the first UE to establish D2D communication with the second UE. 第二UE标识例如可以是第二UE的临时移动用户标识(S-TMSI)或其他的标识。 The second UE identity, for example, may be a temporary mobile subscriber identity (S-TMSI), or other identification of a second UE. 在此,第一UE可以向基站发送RRC连接建立请求消息,所述RRC连接建立请求消息中携带所述第二UE标识。 Here, the first UE to the base station may send an RRC connection establishment request message, the RRC connection establishment request message carries the second UE identity.

[0059] 上述步骤301-303与图2中的步骤201-203对应。 [0059] Step 301-303201-203 above corresponds to step 2 in FIG.

[0060] 步骤304:基站响应于所述第二UE标识将第一UE与第二UE的D2D链路配置参数和RRC连接配置参数发送给第一UE,并且还将第二UE的TA值和/或发射功率值信息发送给第一UE。 [0060] Step 304: The base station in response to the second UE sends identification D2D link configuration parameters of the first UE and the second UE and the RRC connection configuration parameters to the first UE, and also the second UE and the TA value / or transmission power value information to the first UE. 也可能的是,第一UE和第二UE共享TA值和/或发射功率值,此时基站向第一UE发送第二UE与第一UE共享TA值和/或发射功率值的指示信息。 It is also possible that the first and second UE share the TA value and / or transmission power value, at this time the base station transmits a second indication information to the first UE UE share the TA value and / or transmission power value to the first UE. 在此,基站可以向第一UE发送RRC连接建立消息,在RRC连接建立消息中携带上述第一UE与第二UE的D2D链路配置参数和RRC连接配置参数、以及第二UE的TA值和/或发射功率值信息或者第二UE与第一UE共享TA值和/或发射功率值的指示信息。 Here, the base station may be connected to the first UE sends an RRC establishment message carries the above-mentioned configuration parameters and D2D link RRC connection configuration parameters of the first UE and the second UE in the RRC connection setup message, and the second UE and the TA value / or indication information or the second transmit power value information of the UE and the UE share the TA values ​​of the first and / or transmit power values. 也可能的是,基站通过D2D-C-RNTI加扰物理下行控制信道(PDCCH)向第一UE发送上述信息的调度信息,从而第一UE利用D2D-C-RNTI解扰物理下行控制信道PDCCH获取调度信息,并进一步根据所述调度信息获取上述信息。 It is also possible that the base station scrambling physical downlink control channel (PDCCH) by D2D-C-RNTI transmits scheduling information to the information of the first UE, so that the first UE using the D2D-C-RNTI descrambling obtain a PDCCH scheduling information, and further acquires the information according to the scheduling information. 同样地,在利用D2D-C-RNTI来传送调度信息的情况下,第一UE需要首先获取基站分配的D2D-C-RNTI。 Similarly, in the case of using D2D-C-RNTI to transmit the scheduling information, the UE needs to first obtain a first D2D-C-RNTI assigned to the base station. 关于此的具体说明可以参见前面结合图2描述的实施例,这里不再赘述。 DETAILED DESCRIPTION on this can be found in the foregoing embodiment described in conjunction with FIG. 2, is omitted here.

[0061] 由于第一UE和第二UE的很多配置都是相同的,因此第一UE和第二UE的配置信息可以使用Delta配置以便于节省消息资源。 [0061] Since many configuration of the first and second UE are the same, the first UE and the second UE configuration information may be configured so as to save the Delta message resources. 在本发明实施例中,Delta配置的含义是,相同的配置信息仅仅出现一次,从而可以节省消息资源。 In an embodiment of the present invention, the meaning Delta configuration is the same configuration information appears only once, thus saving resources message.

[0062] 步骤305:第一UE向第二UE发送第二UE的D2D链路配置参数和RRC连接配置参数、以及第二UE的TA值和/或发射功率值信息,或者向第二UE发送第二UE的D2D链路配置参数和RRC连接配置参数、以及共享的TA值和/或发射功率值。 [0062] Step 305: a first connection to the second UE UE transmit the D2D link configuration parameters and the second UE RRC configuration parameters, the UE and the TA value of the second and / or transmit power value information, or send the second UE D2D link configuration parameters of the second UE and the RRC connection configuration parameters, and the shared values ​​of the TA and / or transmit power values. 由此,第二UE相应地接收由第一UE发送的第二UE的D2D链路配置参数和RRC连接配置参数以及TA值和/或发射功率值。 Accordingly, the second UE receive respective D2D link configuration parameters sent by the second UE and the first UE and the RRC connection configuration parameter values ​​TA and / or transmit power values. 这里也可能的是,第一UE向第二UE发送D2D小区无线网络临时标识D2D-C-RNTI,所述D2D-C-RNTI用于第二UE从物理下行控制信道PDCCH获取第二UE的调度信息,使得第二UE能够利用D2D-C-RNTI解扰物理下行控制信道PDCCH获取基站发送的调度信息,并进一步根据所述调度信息获取所述第二UE的上述信息。 Here it is also possible that the UE transmits a first cell radio network temporary identity D2D D2D-C-RNTI to the second UE, wherein the D2D-C-RNTI for the UE acquiring a second schedule from a second UE a PDCCH information, such that the second UE can use D2D-C-RNTI descrambling obtain a PDCCH scheduling information transmitted from the base station, and further acquires the information of the second UE according to the scheduling information.

[0063] 步骤306:第一UE与所述第二UE建立D2D连接,并基于第一UE的RRC连接配置参数完成与基站的RRC连接建立,而第二UE与所述第一UE建立D2D连接,并基于第二UE的RRC连接配置参数完成与基站的RRC连接建立。 [0063] Step 306: establishing a first UE and the second UE D2D connection, the first UE based RRC connection with the RRC configuration parameters to complete the connection establishment the base station and the second UE establishes a connection with the first UE D2D and, based on the second UE RRC connection configuration parameters to complete the RRC connection with the base station is established. 由于通过步骤304,第一UE获得了其D2D链路配置参数,而通过步骤305,第二UE获得了其D2D链路配置参数,因此第一UE和第二UE可以建立彼此间的D2D连接。 Since in step 304, the UE obtains its first D2D link configuration parameters, in step 305, the UE obtains its second D2D link configuration parameters, the first and second UE D2D connection may be established between them.

[0064] 在第二UE完成配置后,可以向第一UE反馈Uu RRC连接(即第二UE和基站之间的RRC连接)建立完成,以及Ud D2D链路(即第一UE和第二UE之间的D2D链路)配置完成消息。 [0064] After the completion of the second UE configuration can be fed the Uu RRC connection (i.e., an RRC connection between the UE and the second base station) to complete the establishment of the first UE, and Ud D2D link (i.e., the first and second UE D2D link between) configuration complete message. 而第一 UE在接收到第二UE反馈的RRC连接建立完成以及D2D链路配置完成消息后,可以由第一UE统一向基站发送RRC连接建立完成消息和D2D配置完成消息。 And the first UE after the second UE receiving the RRC connection setup complete fed back and D2D link reconfiguration complete message, sent by the first UE may be unified to the base station and the RRC connection setup complete message D2D configuration complete message.

[0065] 在本实施例中,第二UE的TA值和/或发射功率值可以是与第一UE共享的TA值和/或发射功率值。 [0065] embodiment, TA value of the second UE, and / or transmit power values ​​in the present embodiment may be shared with the first UE and the TA value / or transmit power values. 同样可以有多种方式来确定第一UE是否与第二UE共享TA值和/或发射功率值。 Also there may be several ways to determine whether the first UE share the TA value and / or transmission power value and the second UE. 关于此内容可以参见前面结合图2所描述的实施例,这里不再赘述。 This content may be found on the foregoing two embodiments described in conjunction with FIG omitted here.

[0066] 本实施例中的TA值更新过程与图2所示实施例相同,不再赘述。 [0066] The present value TA update procedure in the embodiment of FIG same as shown in Example 2, is omitted.
