Description

一种实现设备直通中继选择的方法、网络控制节点及用户设备Method for implementing device direct relay selection, network control node and user equipment 技术领域Technical field
本申请涉及但不限于D2D通信技术，尤指一种实现设备直通中继选择的方法、网络控制节点和用户设备。The present application relates to, but is not limited to, D2D communication technology, and in particular, to a method for implementing device direct relay selection, a network control node, and a user equipment.
背景技术Background technique
随着无线多媒体业务的发展，人们对高数据速率和用户体验的需求日益增长，从而对传统蜂窝网络的系统容量和覆盖提出了较高要求。另一方面公共安全、社交网络、近距离数据共享、本地广告等应用场景使得人们对了解附近人或事物并与之通信的邻近服务(Proximity Services，ProSe)的需求逐渐增加。传统的以基站为中心的蜂窝网络在高数据速率以及邻近服务的支持方面存在明显的局限性，代表未来通信技术发展新方向的设备到设备(Device-to-Device，简称D2D)技术在这种需求背景下应运而生。D2D技术的应用，可以减轻蜂窝网络的负担、减少用户设备的电池功耗、提高数据速率，并改善网络基础设施的鲁棒性，很好地满足上述高数据速率业务和邻近服务的要求。目前的D2D又被称为邻近服务(ProSe，Proximity Services)或是旁链传输(Sidelink Transmission)。With the development of wireless multimedia services, people's demand for high data rates and user experience is increasing, which puts high demands on the system capacity and coverage of traditional cellular networks. On the other hand, application scenarios such as public safety, social networking, close-range data sharing, and local advertising have led to an increasing demand for proximity services (Proximity Services, ProSe) that understand and communicate with nearby people or things. The traditional base station-centric cellular network has obvious limitations in supporting high data rates and proximity services, and Device-to-Device (D2D) technology, which represents a new direction for future communication technologies, is in this category. The background of demand came into being. The application of D2D technology can reduce the burden of cellular networks, reduce the battery power consumption of user equipment, increase the data rate, and improve the robustness of the network infrastructure, which satisfies the requirements of the above high data rate services and proximity services. The current D2D is also known as ProSe (Proximity Services) or Sidelink Transmission.
D2D技术可以工作在授权频段或非授权频段，允许多个支持D2D功能的用户设备，即D2D用户设备(D2D User Equipment，D2D UE，又可称之为ProSe enabled UE)在有网络基础设施或无网络基础设施的情况下进行直接发现/直接通信。D2D的应用场景主要有三种，图1为相关的D2D应用场景示意图，如图1所示，场景1、用户设备在蜂窝网络的覆盖下进行数据交互，用户面数据不经过网络基础设施；场景2、在弱/无覆盖区域的UE中继传输，允许信号质量较差的用户设备(如图中的UE4)通过附近有网络覆盖的其他用户设备(如UE3)与网络进行通信，能帮助运营商扩展覆盖、提高容量；场景3、设备间直接通信，主要应用在发生地震或紧急情况，蜂窝网络不能正常工作时，如图中的UE5、UE6和UE7之间的控制面和用户面都不经过网络基础设施而进行一跳或多跳的数据通信。 The D2D technology can work in the licensed or unlicensed frequency band, and allows multiple D2D-enabled user equipments, that is, D2D User Equipment (D2D User Equipment, also known as ProSe enabled UE) in the network infrastructure or none. Direct discovery/direct communication in the case of network infrastructure. There are three main application scenarios of D2D. Figure 1 is a schematic diagram of related D2D application scenarios. As shown in Figure 1, scenario 1, user equipment performs data interaction under the coverage of the cellular network, and user plane data does not pass through the network infrastructure; scenario 2 The UE relay transmission in the weak/uncovered area allows the user equipment with poor signal quality (such as UE4 in the figure) to communicate with the network through other user equipments (such as UE3) with network coverage nearby, which can help the operator. Expand coverage and increase capacity; scenario 3, direct communication between devices, mainly used in earthquakes or emergencies, when the cellular network is not working properly, the control plane and user plane between UE5, UE6 and UE7 in the figure are not One-hop or multi-hop data communication for network infrastructure.
D2D技术通常包括D2D发现技术和D2D通信技术，其中，D2D发现技术是指用于判断/确定用户设备之间是否邻近的技术。相关的方法对场景1的D2D用户设备、主要通过发送或接收发现信号/信息来发现对方、场景2和场景3的并未确定相应的解决方法，即未给出选择中继节点的解决方案。The D2D technology generally includes a D2D discovery technology and a D2D communication technology, wherein the D2D discovery technology refers to a technique for determining/determining whether or not a user equipment is adjacent. The related method does not determine a corresponding solution to the D2D user equipment of the scene 1, mainly by transmitting or receiving the discovery signal/information to discover the other party, the scene 2 and the scene 3, that is, the solution for selecting the relay node is not given.

The technical problem to be solved by the embodiments of the present invention is the problem of relay selection from UE to network relay and UE to UE relay in the device through-system. The embodiment gives a specific possible selection method of the relay and access relay node and related signaling procedures.
实施例1～实施例5是通过基站以及用户设备选择中继节点或是自治的判断是否需要称为中继节点的过程。 Embodiments 1 to 5 are processes for determining whether or not a relay node is required by a base station and a user equipment to select a relay node or autonomous.
实施例1Example 1
Officer A、B、C、D(Officer A、B、C、D泛指使用用户设备的工作人员)使用具备D2D功能的公共安全用户设备(UE)1、UE2、UE3及UE4。Officer A、B、C和D都订阅了公共安全服务。在救援地点，UE1和UE2处于有网络覆盖状态，而UE3和UE4处于无网络覆盖。考虑到邻近的基站被损坏，处于有网络覆盖的UE1和UE2都有兴趣成为中继节点，为无覆盖的UE3及UE4提供中继服务，如UE1和UE2都对成为终端到网络的中继(UE-to-network relay)感兴趣。Officers A, B, C, and D (Officer A, B, C, and D refer to workers using user equipment) use Public Safety User Equipment (UE) 1, UE2, UE3, and UE4 with D2D capabilities. Officers A, B, C, and D all subscribe to public safety services. At the rescue location, UE1 and UE2 are in network coverage state, while UE3 and UE4 are in network coverage. Considering that the neighboring base stations are damaged, UE1 and UE2 in network coverage are interested in becoming relay nodes, and provide relay services for UE3 and UE4 without coverage. For example, UE1 and UE2 are both terminal-to-network relays ( UE-to-network relay) is interested.
此时UE1和UE2可发送D2D中继相关信息给网络控制节点(以下以基站作为网络控制节点为例进行说明)，其中包括对relay的兴趣指示，希望成为的中继类型(可以是UE-to-network relay和或UE-to-UE relay)，还可以包含UE的剩余电量(如果是插电UE，则剩余电量可指示为无穷)，以及UE当前的地理位置，图14为本发明第一实施例实现设备直通中继选择的信息交互示意图，如图14所示，基站接收到UE1和UE2发送的D2D中继相关信息后，根据地理位置，如果发现UE1和UE2距离较近，并且在UE1和UE2周围并没有其他可用的中继节点，则基站可以随机的在UE1和UE2之间选择一个作为终端到网络的中继节点，假设选择UE1作为中继节点，则基站向UE1发送设备直通中继配置，其中包含UE-to-network relay配置建立信息；可选的，可包含中继标识、和/或中继类型、和/或中继时长/中继时间区间、中继发送和/或接收资源等字段。此外基站还可以根据预定义规则以及接收到的UE的中继相关信息，选择或释放中继节点，例如，根据UE1剩余电量高，地理位置处于小区边缘、选择UE1作为UE-to-network relay节点。与此 同时，如果基站接收到已经被配置成为UE-to-network relay节点的UE5的上报，发现UE5的剩余电量较低或是UE5移动到小区中心已经不再适合做中继节点，则基站可向UE5发送设备直通中继配置，其中包含UE-to-network relay配置释放信息。At this time, UE1 and UE2 can send D2D relay related information to the network control node (hereinafter, the base station is used as a network control node as an example), which includes an indication of interest to the relay, and a desired relay type (may be UE-to -network relay and or UE-to-UE relay), may also include the remaining power of the UE (if the UE is plugged in, the remaining power may be indicated as infinity), and the current geographic location of the UE, FIG. 14 is the first in the present invention. The embodiment implements the information exchange diagram of the device through relay selection. As shown in FIG. 14 , after receiving the D2D relay related information sent by the UE1 and the UE2, the base station finds that the UE1 and the UE2 are close to each other according to the geographic location, and is in the UE1. And there is no other available relay node around the UE2, the base station can randomly select a relay node between the UE1 and the UE2 as the terminal to the network. If the UE1 is selected as the relay node, the base station sends the device through to the UE1. Following configuration, including UE-to-network relay configuration establishment information; optionally, may include a relay identifier, and/or a relay type, and/or a relay duration/relay time interval, a relay transmission, and / or receive fields such as resources. In addition, the base station may also select or release the relay node according to the predefined rule and the relay related information of the received UE. For example, according to the high remaining capacity of the UE1, the geographical location is at the cell edge, and the UE1 is selected as the UE-to-network relay node. . With this Meanwhile, if the base station receives the report of the UE 5 that has been configured as the UE-to-network relay node, and finds that the remaining power of the UE 5 is low or the UE 5 moves to the cell center and is no longer suitable as a relay node, the base station may send the UE 5 The sending device direct-through trunk configuration includes UE-to-network relay configuration release information.
UE1接收基站发送的设备直通中继配置，根据设备直通中继配置执行中继功能的建立，而UE5则可以根据设备直通中继配置执行中继功能的释放。The UE1 receives the device pass-through trunk configuration sent by the base station, performs the establishment of the relay function according to the device pass-through trunk configuration, and the UE5 can perform the release of the relay function according to the device pass-through trunk configuration.
除了UE主动向基站发送用户设备感兴趣，如果基站支持设备直通中继功能，可在触发中继节点选择之前，首先发送中继相关信息的请求信息给具备中继能力的UE或是发送中继相关信息上报配置给具备中继能力的UE，其中中继相关信息上报配置包括事件上报或周期性上报，以及需要上报的中继相关信息种类等，从而使得基站可以不断收到更新的具备中继能力的UE的状态信息，如果发现UE的中继相关信息发生变化，如中继负荷状态、监听到的寻找中继用户设备的信息、已配置为设备直通中继节点的用户设备上报的移动状态/剩余电量变化超出系统预配置的门限，则基站可以进行中继节点的释放或是重配置。In addition to the UE actively transmitting the user equipment to the base station, if the base station supports the device direct-through relay function, the relay-related information may be first sent to the relay-capable UE or the relay before the triggering of the relay node selection. The related information is reported and configured to the relay-capable UE, where the relay-related information reporting configuration includes event reporting or periodic reporting, and types of relay-related information that need to be reported, so that the base station can continuously receive updated relays. Status information of the UE, if the UE's relay-related information is changed, such as the relay load status, the information of the monitored relay user equipment, and the mobile status reported by the user equipment configured as the device pass-through relay node. / If the remaining power changes beyond the pre-configured threshold, the base station can release or reconfigure the relay node.
UE向基站发送的D2D中继相关信息除了上述描述的relay的兴趣、希望成为的中继类型、UE的剩余电量以及UE当前的地理位置，还可以包含UE所属设备直通组、UE的中继可用时段、UE的移动状态指示、UE的中继收发能力、UE的处理能力、UE的中继计费需求、UE的蜂窝和设备直通业务流量等一个或一个以上信息。对于已经成为中继节点的UE，在周期性或是事件触发向基站上报D2D中继状态信息时，还可上报UE的中继负荷状态。其中UE的中继可用时段指UE可用作设备直通中继的时间区间；UE的移动状态指示包括：快，中，慢等不同的移动速度指示；UE的中继收发能力指UE是否有专门的收发机硬件用于中继收发；UE的处理能力指用户设备的硬件配置能力或能力等级，体现用户设备CPU个数、主频、内存的不同或是数据包处理效率；UE的中继计费需求指用户设备对中继数据转发期望的每数据单位/时间单位的价格补偿；UE当前的蜂窝业务流量包括：UE当前的上行/下行蜂窝流量；UE当前的设备直通业务流量包括：UE当前的设备直通发现/通信数据流量；UE中继负荷状态可以是UE作为中继所转发的数据流量， 也可以是UE中继转发的负荷指示，如高、中、低等。基站可以综合考虑上述信息，选择或释放中继节点，例如，预先确定选择具有以下中继相关信息的用户设备作为中继节点：如剩余电量高、和/或移动状态低、和/或蜂窝链路质量好、和/或地理位置处于无覆盖区域边缘、和/或地理位置处于小区边缘、和/或处理能力强、和/或计费要求低、和/或蜂窝和设备直通业务流量低的用户设备；预先确定具有以下特征的中继节点：释放剩余电量低、和/或移动状态高、和/或地理位置处于小区中心、和/或处理能力弱、和/或计费要求高、和/或蜂窝和设备直通业务流量高的用户设备。The D2D relay related information sent by the UE to the base station may include, in addition to the interest of the relay described above, the type of the relay to be used, the remaining power of the UE, and the current geographic location of the UE, the device may also include the device through group to which the UE belongs, and the relay of the UE is available. One or more pieces of information, such as a time period, a mobile state indication of the UE, a relay transceiving capability of the UE, a processing capability of the UE, a relay charging requirement of the UE, a cellular and a device through traffic of the UE, and the like. For a UE that has become a relay node, when the D2D relay status information is reported to the base station by a periodic or event trigger, the relay load status of the UE may also be reported. The relay available period of the UE refers to a time interval in which the UE can be used as a device through relay; the mobile state indication of the UE includes: different speed indications such as fast, medium, and slow; and the relay sending and receiving capability of the UE refers to whether the UE has a special The transceiver hardware is used for relaying and receiving; the processing capability of the UE refers to the hardware configuration capability or capability level of the user equipment, which reflects the number of CPUs of the user equipment, the frequency of the main equipment, the memory, or the efficiency of data packet processing; The fee requirement refers to the price compensation per unit of data/time unit expected by the user equipment for relay data forwarding; the current cellular service traffic of the UE includes: the current uplink/downlink cellular traffic of the UE; the current device direct traffic of the UE includes: the current UE The device directly passes the discovery/communication data traffic; the UE relay load state may be the data traffic forwarded by the UE as a relay, It may also be a load indication that the UE relays, such as high, medium, and low.

UE1 and UE2 are within D2D communication range of each other, UE2 and UE3 are within D2D communication range of each other, and UE1 and UE3 are not within D2D communication range of each other. UE1, UE2, and UE2 may obtain D2D relay receiving resource pool information through pre-configuration, and may also receive D2D relay resource pool information that the base station sends through broadcast or proprietary signaling. Assuming that the UE1 wishes to transmit the data packet to the UE3 that is not in the D2D communication range by means of relaying, the UE1 can transmit the broadcast message for finding the D2D relay using the resources of the D2D relay resource pool. Assuming that UE2 has an intent/interest/indication to become a relay node, UE2 can listen to the D2D relay resource pool to see if there is a UE looking for a D2D relay.
假设UE2监听到UE1发送的寻找D2D中继的信息，则UE2可向基站发送D2D中继相关信息给基站。图15为本发明第二实施例实现设备直通中继选择的信息交互示意图，如图15所示，UE2监听到的寻找D2D中继的UE1的信息，包括：监听到的寻找D2D中继的UE个数、寻找D2D中继UE的标识、UE寻找的D2D中继类型、寻找D2D中继的UE1的通信目标标识(UE3的标识)、UE2是否与UE1的通信目标节点UE3能否互相发现、UE2对寻找D2D中继UE1的测量结果(UE2对寻找中继用户设备发送的信号强度测量或对于相应参考信号的类似于RSRP/RSRQ的测量)、寻找D2D中继UE1的流量及服务质量需求、寻找D2D中继的UE1的覆盖状态、寻找D2D中继UE1的服务小区标识等其中的一个或一个以上信息。上述信息部分通过UE2接收UE1发送的寻找D2D中继广播消息获得，部分通过UE2的测量获得。Assuming that UE2 listens to the information of the D2D relay sent by UE1, UE2 may send D2D relay related information to the base station to the base station. FIG. 15 is a schematic diagram of information exchange for implementing device direct relay selection according to a second embodiment of the present invention. As shown in FIG. 15, the information of UE1 that is monitored by UE2 for searching for D2D relay includes: the monitored UE that is looking for D2D relay. The number, the ID of the D2D relay UE, the D2D relay type that the UE is looking for, the communication target identifier of the UE1 that is looking for the D2D relay (the identifier of the UE3), whether the UE2 and the communication target node UE3 of the UE1 can discover each other, the UE2 Finding the measurement result of the D2D relay UE1 (the UE2 is looking for the signal strength measurement sent by the relay user equipment or the RSRP/RSRQ measurement for the corresponding reference signal), searching for the traffic and service quality requirements of the D2D relay UE1, searching for One or more pieces of information of the coverage state of the UE1 of the D2D relay, the search for the serving cell identity of the D2D relay UE1, and the like. The above information is obtained by the UE2 receiving the D2D relay broadcast message sent by the UE1, and partially obtained by the measurement of the UE2.
基站接收到UE2发送的D2D中继相关信息后，如果UE2能发现寻找中 继的UE1的目标通信节点UE3，并且此时只有一个候选的中继节点UE2，则基站选择UE1作为UE1与UE3之间D2D通信的用户设备到用户设备的中继节点(UE-to-UE relay)。如果基站接收到多个具备D2D中继能力的UE的上报，并且都能够同时发现UE1和UE3，则基站可以随机的在这些候选用户设备之中选择一个作为UE-to-UE relay节点，假设选择UE2作为中继节点，则基站向UE2发送设备直通中继配置，其中包含UE-to-UE relay配置建立信息，可选的，可包含中继标识、中继类型、中继时长/中继时间区间、中继资源配置等字段。此外基站还可以根据预定义规则以及接收到的UE的中继相关信息，选择或释放中继节点。After the base station receives the D2D relay related information sent by the UE2, if the UE2 can find the search Following the target communication node UE3 of UE1, and there is only one candidate relay node UE2 at this time, the base station selects UE1 as the relay node of the user equipment to the user equipment for D2D communication between UE1 and UE3 (UE-to-UE relay) ). If the base station receives the reporting of multiple D2D relaying UEs and can both discover UE1 and UE3, the base station may randomly select one of the candidate user equipments as the UE-to-UE relay node, assuming that the selection is performed. The UE2 is configured as a relay node, and the base station sends a device direct-through relay configuration to the UE2, where the UE-to-UE relay configuration establishment information is included, and may include a relay identifier, a relay type, a relay duration, or a relay time. Fields such as interval and relay resource configuration. In addition, the base station may also select or release the relay node according to the predefined rules and the relay related information of the received UE.

Officers A, B, C, and D all subscribe to public safety services. At the rescue location, UE1 and UE2 are in network coverage state, while UE3 and UE4 are in network coverage. Considering that the neighboring base stations are damaged, UE1 and UE2 in network coverage are interested in becoming relay nodes, and provide relay services for uncovered UEs.

UE1和UE2可发送对本小区以及相邻小区的测量报告给基站，其中测量报告包括对本小区以及相邻小区的测量结果RSRP以及RSRQ测量值，图16为本发明第三实施例实现设备直通中继选择的信息交互示意图，如图16所示，基站接收到UE1发送的测量报告后，根据UE1发送的测量结果判断UE的相对位置，如果UE1对本小区的RSRP测量结果大于给定门限，则基站认为具备成为中继的基本条件，基站可以选择UE1作为UE-to-network relay节点，向UE1发送设备直通中继配置，其中包含UE-to-network relay配置建立信息；可选的，可包含中继标识、中继类型、中继时长/中继时间区间，中继资源配置等字段。如果UE1对本小区的RSRP测量结果小于给定门限，则基站认为UE1处于小区边缘；如果UE1测量到的所有邻区的RSRP测量结果小于给定门限或是UE1没有检测到相邻小区，则基站可进一步认为UE1处于 网络覆盖边缘，基站可以优先选择UE1作为UE-to-network relay节点，向UE1发送设备直通中继配置，其中包含UE-to-network relay配置建立信息；可选的，可包含中继标识、中继类型、中继时长/中继时间区间等字段。The UE1 and the UE2 may send a measurement report to the local cell and the neighboring cell to the base station, where the measurement report includes the measurement result RSRP and the RSRQ measurement value for the local cell and the neighboring cell, and FIG. 16 is a device for implementing the device through relay according to the third embodiment of the present invention. As shown in FIG. 16, after receiving the measurement report sent by the UE1, the base station determines the relative position of the UE according to the measurement result sent by the UE1. If the RSRP measurement result of the UE1 is greater than the given threshold, the base station considers With the basic condition of being a relay, the base station may select UE1 as the UE-to-network relay node, and send a device direct-through relay configuration to UE1, which includes UE-to-network relay configuration establishment information; optionally, may include a relay Fields such as identification, relay type, relay duration/relay time interval, and relay resource configuration. If the RSRP measurement result of the UE1 is smaller than the given threshold, the base station considers that the UE1 is at the cell edge; if the RSRP measurement result of all the neighboring cells measured by the UE1 is less than a given threshold or the UE1 does not detect the neighboring cell, the base station may Further believe that UE1 is at The network coverage edge, the base station may preferentially select the UE1 as the UE-to-network relay node, and send the device direct-through relay configuration to the UE1, including the UE-to-network relay configuration establishment information; optionally, the relay identifier may be included, Fields such as type, relay duration/relay time interval.
假设UE2原本已被基站选择为UE-to-network relay节点，但随着UE2的移动，UE2上报的测量报告中UE2对本小区的RSRP测量结果高于给定门限，则基站认为UE2处于小区中心，已不再适合作为UE-to-network relay节点，因此基站向UE2发送设备直通中继配置，其中包含UE-to-network relay配置释放信息。It is assumed that the UE2 has been selected by the base station as a UE-to-network relay node, but the UE2 considers that the UE2 is in the cell center, and the UE2 is in the cell center. It is no longer suitable as a UE-to-network relay node, so the base station sends a device pass-through relay configuration to UE2, which includes UE-to-network relay configuration release information.

UE1和UE2可通过预配置获得D2D中继资源池信息以及中继选择门限信息，也可以接收基站通过广播发送的D2D中继资源池信息以及中继选择门限信息。中继门限包括本小区链路质量测量最低门限、和/或剩余电量门限、和/或移动状态门限。假设UE1处于闲置态，UE1根据自身测量结果判断是否满足中继门限，如果满足中继门限，才开始监听D2D中继接收资源池，图17为本发明第四实施例实现设备直通中继选择的信息交互示意图，如图17所示，当监听不到有相邻的D2D中继节点广播发送的中继广告信息，则UE1认为周围没有中继节点，则UE1可以在给定时间范围内等待随机时间后根据预配置执行D2D中继功能，并开始广播发送D2D中继广告消 息。对于UE2，如果此时监听到相邻的中继节点广播发送的D2D中继广告消息，则进一步判断相邻的设备直通中继用户设备的中继类型以及对接收到的中继广告信息测量结果，如果UE2能检测到UE1广播发送的中继广告信息，但是对应的中继广告信息的信号测量值低于给定门限，则UE2将自己也配置为中继节点，如果UE2不能检测到UE1广播发送的中继广告信息，或者UE2虽能检测到UE1广播发送的中继广告信息，但是对应的中继广告信息的信号测量值高于或等于给定门限，UE2不配置自己为中继节点。The UE2 and the UE2 may obtain the D2D relay resource pool information and the relay selection threshold information through pre-configuration, and may also receive the D2D relay resource pool information and the relay selection threshold information that are sent by the base station through the broadcast.

The relay advertisement information transmitted, or the UE2 can detect the relay advertisement information broadcasted by the UE1, but the signal measurement value of the corresponding relay advertisement information is higher than or equal to a given threshold, and the UE2 does not configure itself as a relay node.
另外，UE1和UE2还可根据其他预定义规则以及用户设备的中继相关信息，配置或释放自身的中继功能，例如，预先确定选择具有以下中继相关信息的用户设备作为中继节点：如剩余电量高、和/或移动状态低、和/或蜂窝链路质量好、和/或地理位置处于无覆盖区域边缘、和/或地理位置处于小区边缘、和/或处理能力强、和/或计费要求低、和/或蜂窝和设备直通业务流量低的用户设备；预先确定具有以下特征的中继节点释放中继功能：释放剩余电量低、和/或移动状态高、和/或地理位置不再处于无覆盖区域边缘、和/或地理位置处于小区中心、和/或处理能力弱、和/或计费要求高、和/或蜂窝和设备直通业务流量高的用户设备。In addition, UE1 and UE2 may also configure or release their own relay functions according to other predefined rules and relay related information of the user equipment, for example, predetermined selection of user equipment having the following relay related information as a relay node: High remaining power, and/or low mobile state, and/or good cellular link quality, and/or geographic location at the edge of the uncovered area, and/or geographical location at the cell edge, and/or strong processing power, and/or User equipment with low billing requirements, and/or low cellular and device direct traffic; pre-determined relay node release relay function with the following features: release low remaining power, and/or high mobile status, and/or geographic location User equipment that is no longer at the edge of the uncovered area, and/or where the geographic location is at the center of the cell, and/or that has weak processing capabilities, and/or high billing requirements, and/or high cellular and device direct traffic.
UE1根据用户设备中继相关信息选择或配置自己为中继节点之后，如果后续UE1进入连接态，并收到了基站对用户设备的中继配置，则基站发送的中继配置可以覆盖用户设备自治的中继配置。After the UE1 selects or configures itself as the relay node according to the user equipment relay related information, if the subsequent UE1 enters the connected state and receives the relay configuration of the user equipment by the base station, the relay configuration sent by the base station may cover the user equipment autonomy.

The specific information may include: a relay identifier, a relay type, a relay duration, and a relay. Fields such as time intervals. The UE2 receives the device pass-through relay configuration sent by the base station, and performs the establishment of the relay function according to the device through-through relay configuration.
接着eNB向UE1发送接入中继节点配置，设备直通中继接入配置可包括接入中继节点的建立配置，其中包含中继接入节点UE2的标识信息。UE1接收eNB发送的接入中继节点配置信息，然后根据接入中继节点配置执行接入中继节点配置的建立，并开始接入中继节点UE2进行D2D数据转发通信。 The eNB then sends an access relay node configuration to the UE1, and the device direct-through relay access configuration may include an establishment configuration of the access relay node, where the identification information of the relay access node UE2 is included. The UE1 receives the access relay node configuration information sent by the eNB, and then performs establishment of the access relay node configuration according to the access relay node configuration, and starts to access the relay node UE2 for D2D data forwarding communication.
实施例10Example 10
图23为本发明第十实施例实现设备直通中继选择的信息交互示意图，如图23所示，UE1已经选择了relay UE2，并与其建立连接进行数据转发。后续UE1检测到对relay UE2的链路测量结果(S2)低于中继重选直通链路门限，则用户设备开始监听预配置的中继接收资源池。假设UE1监听不到相邻其他中继节点节点广播发送的中继发现信息(即寻找中继信息)，则UE1在中继发送资源池上广播发送寻找D2D中继的消息。假设UE1监听到Relay UE3发送的中继响应信息，则UE1获取其中包含的中继相关信息并对其信号强度进行测量，其测量结果为S3。之后UE1对(S2+中继重选滞后值)，S3进行排序，如果S3值更高，则UE1重选Relay UE3作为接入中继节点，开始尝试建立连接进行D2D数据转发。FIG. 23 is a schematic diagram of information exchange for implementing device direct relay selection according to the tenth embodiment of the present invention. As shown in FIG. 23, UE1 has selected relay UE2 and established a connection with it for data forwarding. After the UE1 detects that the link measurement result (S2) for the relay UE2 is lower than the relay reselection pass-through link threshold, the user equipment starts to listen to the pre-configured relay receiving resource pool. It is assumed that UE1 cannot monitor the relay discovery information broadcasted by neighboring other relay node nodes (that is, look for relay information), and UE1 broadcasts a message for finding a D2D relay on the relay transmission resource pool. It is assumed that the UE1 listens to the relay response information sent by the Relay UE3, and the UE1 acquires the relay related information contained therein and measures the signal strength thereof, and the measurement result is S3. Then UE1 pairs (S2+ relay reselection hysteresis value), S3 is sorted. If the S3 value is higher, UE1 reselects Relay UE3 as the access relay node, and starts to attempt to establish a connection for D2D data forwarding.
