分配网络资源的方法、 接入网络中的目标设备的方法、 基站及终端设备 技术领域
本发明涉及无线通讯技术领域， 尤其涉及一种分配网络资源的方法、 接入网络中的目标设备的方法、 基站及终端设备。
背景技术
在无线通信网络中， 如果终端设备不能由某基站下的小区提供服务， 比如终端设备未处于该基站的信号覆盖范围内、终端设备处于该基站信号 覆盖的漏洞区域、 或基站故障导致无法为该终端设备提供信号覆盖等。 这 些情况下，该终端设备可以通过由该基站或其它基站下的小区所服务的终 端设备接入网络中的目标设备中进行数据的传输。该基站或其它基站下的 小区所服务的这类终端设备称为小区功能用户设备 ( Cell Function User Equipment, CF UE ), 通过该 CF UE接入网络中的目标设备的这类终端设 备称为接入用户设备 （Access User Equipment, AC UE )。 在设备到设备 ( Device to Device, D2D )协议中， AC UE通过检测其它终端设备的信道 可以发现 CF UE。 然而在 D2D协议中， 各个终端设备通过自身的能力以竟 争的方式占用网络资源， 自身的能力强的终端设备占用的网络资源多或优 先占用网络资源， 而能够为 AC UE提供接入到网络服务的 CF UE可能无法 获得足够的网络资源， 导致 AC UE无法发现该 CF UE或发现了 CF UE但不 能通过该 CF UE接入网络中的目标设备的情况。 例如， 距离 AC UE较远的 CF UE通过竟争占用了大量的网络资源， 由于距离较远使得 AC UE检测不 到 CF UE; 距离 AC UE较近的 CF UE由于无法获取足够的网络资源也不能 为 AC UE提供服务， 从而导致资源浪费， 降低了 AC UE的用户体验。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进 行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例， 而不是全部的实施例。基于本发明中的实施例， 本领域普通技术人员在没 有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的 范围。
图 1提供了本发明实施例应用的一种通信系统的架构示意图， 该通信 系统包括： 基站、 第一终端设备以及通过第一终端设备接入到网络中的第 二终端设备。
本发明实施例的典型应用场景为：第二终端设备可能处于该基站服务 小区覆盖范围之外， 也可能处于该基站服务小区覆盖范围的覆盖漏洞中。 简单地说， 该第二终端设备无法直接接收到该基站发送的无线电波， 并通 过该无线电波与该基站的交互而接入网络中的目标设备中。 更进一步， 本 发明实施例还可用于任何第二终端设备需要通过第一终端设备接入到网 络中的场景， 例如， 由于某些紧急业务的需求而为该第二终端设备提供服 务的基站不能满足该紧急业务的需求，第二终端设备可以不接入到为第二 终端设备服务的基站，而通过第一终端设备接入到为第一终端设备服务的 基站中。
本发明实施例提供的技术方案， 可以应用于各种通信系统中， 例如： 全球移动通信系统 ( GSM, Global System of Mobile communication ), 码分多址 ( CDMA, Code Division Multiple Access ) 系统， 宽带码分多 址 ( WCDMA, Wideband Code Division Multiple Access Wireless ), 通 用分组无线业务（ GPRS, General Packet Radio Service ),长期演进（ LTE, Long Term Evolution) 等。
本发明实施例中的终端设备， 也可称之为移动终端 （ Mobile Terminal ), 用户设备 ( User Equipment ) 或移动用户设备等， 可以经无 线接入网 （例如， RAN, Radio Access Network ) 与一个或多个核心网进 行通信， UE 可以是移动终端， 如移动电话 （或称为 "蜂窝" 电话） 和具 有移动终端的计算机， 例如， 可以是便携式、 袖珍式、 手持式、 计算机内 置的或者车载的移动装置， 它们与无线接入网交换语言和 /或数据。
本发明实施例中的基站， 可以是 GSM或 CDMA中的基站 （ BTS, Base Transceiver Station ), 也可以是 WCDMA中的基站 （ NodeB ), 还可以是 LTE 中的演进型基站 （ eNB或 e_NodeB, evolutional Node B ), 还可以是小小 区 （ Small Cell )所对应的小基站， 还可以是各种接入点 （ Access Point, AP) 等， 本发明并不限定。 针对上述场景， 一方面， 本发明实施例提供了一种分配网络资源的方 法， 如图 2所示的分配网络资源的方法流程示意图， 包括以下内容。
201, 基站接收第一终端设备发送的请求信息， 所述请求信息用于请 求该基站分配网络资源。 可选地， 该网络资源可以包括时隙资源、 频率资 源或码道资源。
该基站分配的网络资源用于第二终端设备通过第一终端设备接入目 标设备。可选地，该目标设备可以是第一终端设备发送该请求信息的基站， 也可以该基站的邻基站， 该目标设备也可以是第一终端设备本身， 或者， 该目标设备可以是第一终端设备所在小区中的任何一个通信设备等等。
该基站在分配上述网络资源的过程，基站分配的网络资源可以是基站 指定的第二终端设备通过第一终端设备接入目标设备情况下所使用的时 隙、 频率或码道， 或者基站分配的网络资源也可以是基站从网络管理系统 或该基站的邻基站接收的用于指示第二终端设备通过第一终端设备接入 目标设备情况下所使用的时隙、 频率或码道的信息。 为了该基站下小区所 服务的终端之间占用的网络资源不会冲突，该基站在分配上述网络资源的 过程中， 该基站可以判断为第一终端设备分配的网络资源中时隙、 频率或 码道是否已经被其它终端设备所占用， 如果已经被其它终端设备所占用， 基站从空闲的网络资源中选择为第一终端设备分配的网络资源。
202 , 基站向第一终端设备发送该基站分配的网络资源的分配信息。 该分配信息用于指示基站分配的网络资源。
基站分配的网络资源可以由该基站通过网络资源的分配信息通知给 第一终端设备，第一终端设备根据该基站分配的网络资源的分配信息具体 确定在哪个时隙、哪个频率或哪个码道协助第二终端设备接入到目标设备 中。
在本发明实施例中， 第一终端设备为上述基站下小区所服务的终端， 第二终端设备为需要通过第一终端设备接入目标设备的终端。第二终端设 备可以是该基站下小区所服务的终端，也可以不是该基站下小区所服务的 终端（例如， 该第二终端设备为其它基站下小区所服务的终端， 或者该第 二终端设备不是任何基站下小区所服务的终端）。 本发明实施例中的第二 终端可以是任何需要通过第一终端设备接入目标设备的终端。
可选地，基站分配的网络资源包括在所述第二终端设备通过所述第一 终端设备接入所述目标设备情况下使用的时隙、 频率或码道。
可选地， 在上述方法中， 还包括： 所述基站根据所述基站分配的网络 资源确定信道与网络资源的对应关系， 该对应关系用于指示同步信道、 广 播信道或接入信道所使用的网络资源；基站将该对应关系发送给第一终端 设备。
可选地， 为了不改变无线通信系统中基站本身的资源利用和调度， 基 站分配的网络资源可以是第一终端设备在该基站下小区中进行正常通信 业务所使用的时隙、 频率或码道。 例如 , 资源块 （ Resource Block, RB ) 作为一种 LT E系统中典型的时隙资源和频率资源， 基站分配的网络资源可 以是第一终端设备接入到基站中所使用的 RB , 第二终端设备可以使用与 第一终端设备接入基站所使用的相同 RB与基站进行通信。
本领域技术人员可以理解， 基站分配的网络资源为空闲的网络资源， 且包含能够为第一终端设备所使用， 并使得第二终端设备接入网络中的 目标设备的资源。
可选地，基站可以将网络资源的分配信息通过广播或信令发送至第一 终端设备。
作为一种可能实施方式，基站可以直接在该基站下的小区内广播网络 资源的分配信息， 而不需要在第一终端设备请求基站分配网络资源后， 再向第一终端设备发送该网络资源的分配信息， 这种情况下 201不是必 须的。 第一终端设备从广播中接收到该分配信息， 并根据该分配信息确 定用于使第二终端设备接入网络中的目标设备的网络资源。
作为一个示例， 第一终端设备为 CF UE, 第二终端设备为 AC UE, 在 CF UE 协助 AC UE接入网络中的目标设备的情况下， CF UE通过向基站请 求分配网络资源， 基站为 CF UE分配网络资源， CF UE通过接收基站对网 络资源的分配信息确定在 CF UE 协助 AC UE接入网络中的目标设备情况 下所使用的时隙资源、 频率资源 （例如， 上行或下行信道上使用的频率） 或码道资源。 CF UE可以从基站接收信道与网络资源的对应关系， 并从该 对应关系 中读取在哪个时隙、 哪个频率或哪个码道上使用 SCH ( Synchronization Channel, 同步信道)、 BCH ( Broadcast Channel, 广播 信道） 或 RACH ( Random Access Channel, 接入信道）。 AC UE通过对子 帧 （子帧由时隙构成， 例如一个子帧由至少两个时隙组成） 的监听并对 CF UE协助 AC UE接入目标设备情况下所使用的频率或码道进行搜索， 例 如釆用对整个频谱或整个码道进行搜索。 如果 AC UE使用某子帧、 频率或 码道检测到 SCH, AC UE与 CF UE在该子帧、 频率或码道使用 SCH进行信 道同步； AC UE在完成信道同步后， AC UE可以检测 CF UE所使用网络资 源对应的 BCH, AC UE从 CF UE所使用的网络资源对应的 BCH中读取用于 指示 CF UE所使用的网络资源对应的 RACH的识别信息； AC UE可以根据 该识别信息确定 CF UE所使用的 RACH,并通过 CF UE所使用的 RACH接入 网络中的目标设备。
作为一个示例，第一终端设备和第二终端设备为同一基站下小区所服 务的终端， 第一终端设备为多媒体服务器， 第二终端设备为用户所持有的 手机。为了第二终端设备在观看或收听多媒体业务时能够获得更好的用户 体验， 第二终端设备可以不用通过基站与第一终端设备传输多媒体业务， 而需要直接通过第一终端设备建立多媒体业务的传输。 这种情况下， 第一 终端设备就是目标设备，第一终端设备可以请求基站分配用于第二终端设 备通过第 ―终端设备接入该第 ―终端设备的网络资源，以便第一终端设备 和第二终端设备可以建立多媒体业务而不需要基站中转多媒体业务。
作为一个示例， 第一终端设备为某基站下小区所服务的终端， 第二终 端设备不是该基站下小区所服务的终端， 例如， 由于第二终端设备距离该 基站过远， 导致无法接收到该基站发射的无线信号而不能进行通信业务。 如果第二终端设备需要进行通信业务并且能够发现第一终端设备，就可以 通过第一终端设备接入到该基站或该基站的邻基站中发起业务。第一终端 设备可以请求基站分配用于将第二终端设备接入到该基站或该基站的邻 基站的网络资源。 这种情况下， 目标设备为该基站或该基站的邻基站， 第 一终端设备对于第二终端设备来说类似于 "中继" 或者第二终端设备的 "拉远天线" 的作用。
在现有技术中， CF UE通过自身的能力以竟争方式获取用于协助 AC UE 接入网络中的目标设备的网络资源， CF UE以自身能力通过竟争方式获取 该网络资源的方式， 由于不是由基站统一调度和分配的网络资源， 不同的 CF UE以自身的能力占用的网络资源实际可能不是可用的和空闲的， 并不 能够协助 A C U E接入到网络中或者由于自身能力较弱导致无法占用足够的 网络资源为第二终端设备服务。 应用本发明实施例提供的技术方案， 基站 为第一终端设备分配用于协助第二终端设备接入目标设备的网络资源，该 网络资源不是由第一终端设备通过自身的能力通过竟争的方式获得的，由 于基站本身具有对其所服务的终端设备具有调度功能，基站很容易获知哪 些网络资源可用的空闲的，哪些网络资源可以更高效地协助第二终端设备 接入到网络中， 因而可以避免由于 CF UE通过竟争占用网络资源而导致网 络资源没有被合理利用的问题，从而节省了网络资源并提高了第二终端设 备的用户体验。 本发明实施例另一方面还提供一种分配网络资源的方法，该方法是对 如图 2所示的方法实施例中第一终端设备所执行的动作的细化，对于如图 2 所示的方法实施例中的概念和过程也适用于本实施例。图 3 a为本实施例所 示网络资源分配的方法的流程示意图， 包括以下内容。
301 , 第一终端设备向基站发送请求信息， 该请求信息用于请求基站 分配网络资源，基站分配的网络资源用于第二终端设备通过第一终端设备 接入到目标设备。 可选地， 该网络资源包括时隙资源、 频率资源和 /或码 道资源。
302 , 第一终端设备接收该基站发送的网络资源的分配信息， 该分配 信息用于指示基站分配的网络资源。
本实施例中， 第一终端设备为该基站下小区所服务的终端， 第二终端 设备为需要通过第一终端设备接入网络中的目标设备的终端。
作为一个示例，在第二终端设备处于基站的服务小区的信号覆盖漏洞 区域、基站信号覆盖的边缘等情况， 第二终端设备不能直接与该基站进行 通信以接入网络中的目标设备，第二终端设备需要与该基站小区所服务的 其它终端设备进行通信以接入网络中的目标设备。 例如， 第二终端设备可 以通过广播的方式请求能够为其提供接入网络中的目标设备服务的终端 设备。 如果第一终端设备接收到第二终端设备的请求， 并根据当前所处的 位置或第二终端设备当前业务的紧急程度等因素确定可以为第二终端设 备提供接入网络中的目标设备的服务，第一终端设备向基站请求分配用于 第二终端设备通过第一终端设备接入网络中的目标设备的网络资源。在第 一终端设备根据从基站接收到的网络资源的分配信息确定了基站分配的 网络资源后，第一终端设备可以将网络资源的分配信息和该第一终端设备 的标识发送给第二终端设备，使得第二终端设备能够获知该网络资源是基 站为第一终端设备协助第二终端设备接入网络中的目标设备情况下第一 终端设备所使用的网络资源，第二终端设备根据该网络资源通过第一终端 设备接入到网络中。 作为另一个示例， 网络 （例如网络管理系统或基站） 可以指定第一终端设备为第二终端设备提供接入网络中的目标设备服务 的基站服务小区下终端 （即 CF UE )。 第一终端设备向基站请求分配网络 资源，该网络资源用于第二终端设备通过第一终端设备接入网络中的目标 设备。 可选地， 如果基站能够预先获知第一终端设备为第二终端设备提供 接入网络中目标设备的 CF UE , 基站也可以直接向第一终端设备发送该基 站分配的网络资源，而不需要第一终端设备请求基站分配网络资源后再为 第一终端设备分配网络资源。在第一终端设备确定了基站分配的网络资源 后， 第二终端设备在时隙上通过对频率或码道搜索基站分配的网络资源， 并在搜索到该网络资源时，第二终端设备根据该网络资源通过第一终端设 备接入网络中的目标设备。
可选地， 在分配网络资源的方法中， 还可以包括：
第一终端设备接收基站发送的信道与基站分配的网络资源的对应关 系， 所述对应关系用于指示同步信道、 广播信道或接入信道所使用的网络 资源；
所述第一终端设备根据所述对应关系将所述第二终端设备接入到目 标设备。
例如：第一终端设备根据基站分配的网络资源的分配信息确定基站所 分配的频率资源为 890MHZ-915MHz和 890MHz-915MHz两个频段。 第一终 端设备进一步可以根据信道与网络资源的对应关系，确定了基站所分配的 频率资源为 890MHz-915MHz使用同步信道和 890MHz-909MHz使用接入 信道。 第一终端设备作为 CF UE在 890MHz-915MHz使用同步信道和广播 信道， 在 890MHz-909MHz使用接入信道， 并且在广播信道上广播用于指 示使用接入信道的频段为 890MHz-909MHz的指示信息。 第二终端设备作 为 AC UE , 可以通过搜索整个无线频段， 确定第一终端设备在 890MHz-915MHz上使用的是同步信道和广播信道， 并在进行信道同步后 , 读取广播信道中第一终端设备广播的指示信息，并根据该指示信息确定第 一终端设备使用接入信道的频段为 890MHz -909MHz。 第二终端设备使用 890MHz-909MHz上的接入信道发起接入， 通过第一终端设备接入网络中 的目标设备。
再例如，第一终端设备根据网络资源的分配信息确定基站所分配的网 络资源为码道 1和码道 2 ,第一终端设备在码道 1使用同步信道和广播信道， 在码道 2使用接入信道， 并且第一终端设备在广播信道上广播用于指示第 一终端设备在码道 2使用的接入信道的指示信息。 第二终端设备通过搜索 各个码道， 在码道 1上确定第一终端设备使用同步信道和广播信道； 第二 终端设备使用该同步信道进行信道同步后，读取广播信道中广播的指示信 息， 并根据该指示信息确定第一终端设备在码道 2使用接入信道； 第二终 端设备通过码道 2上的接入信道发起接入过程接入网络中的目标设备。
可选地，第一终端设备接收的网络资源的分配信息由基站通过信令或 广播发送至第一终端设备。
例如， 在第一终端设备请求基站分配网络资源时， 基站可以将网络资 源的分配信息封装在 RRC信令中发送至第一终端设备。基站也可以将网络 资源的分配信息在该基站的服务小区内广播，第一终端设备可以从广播中 获取网络资源的分配信息。
例如， 如图 3b所示的网络资源的分配示意图， 基站为第一终端设备分 配的网络资源，第一终端设备可以根据基站发送的网络资源的分配信息确 定该网络资源为子帧 2、 3和 6 , 并根据基站发送的信道与子帧的对应关系， 确定在第二终端设备通过第一终端设备接入到目标设备情况下，第一终端 设备在子帧 2使用同步信道， 在子帧 3使用广播信道， 在子帧 6使用接入信 道。 第一终端设备可以在子帧 3使用的广播信道中广播用于指示第一终端 设备在子帧 6使用接入信道的指示信息。第二终端设备通过搜索各个子帧， 确定第一终端设备在子帧 2上使用同步信道并进行信道同步， 确定第一终 端设备在子帧 3上使用广播信道并从广播信道获知第一终端设备在子帧 6 使用接入信道。 第二终端设备通过在子帧 6使用接入信道通过第一终端设 备接入网络中的目标设备中。
在现有技术中， CF UE通过自身的能力以竟争方式获取用于协助 AC UE 接入网络中的目标设备的网络资源，由于不是由基站统一调度和分配的网 络资源， CF UE占用的网络资源可能并不能够协助 AC UE接入到网络中或者 由于自身能力较弱导致无法占用足够的网络资源为第二终端设备服务。应 用本发明实施例提供的技术方案，基站为第一终端设备分配用于协助第二 终端设备接入目标设备的网络资源，该网络资源不是由第一终端设备通过 自身的能力通过竟争的方式获得的，由于基站本身具有对其所服务的终端 设备具有调度功能， 基站很容易获知哪些网络资源可用， 哪些网络资源可 以更高效地协助第二终端设备接入到网络中， 因而可以避免由于 CF UE通 过竟争占用网络资源而导致的资源浪费的问题，从而节省了网络资源并提 高了第二终端设备的用户体验。
本发明实施例一方面还提供一种接入网络中的目标设备的方法，该方 法是对如图 2或图 3所示的方法实施例的进一步扩展，图 2或图 3所示的实施 例中的概念和过程仍适用于本实施例， 如图 4所示的接入网络中的目标设 备方法的流程示意图， 该方法包括以下内容。
401 , 第二终端设备确定第一终端设备所使用的网络资源， 该网络资 源用于所述第二终端设备通过所述第一终端设备接入目标设备，该网络资 源由基站分配。 其中， 第一终端设备为该基站服务小区的终端， 第二终端 设备为需要通过第一终端设备接入网络中的目标设备的终端。
作为一个示例，第一终端设备可以将所使用的网络资源的分配信息进 行广播。如果第二终端设备需要通过第一终端设备接入到网络中的目标设 备中， 第二终端设备可以从广播中读取网络资源的分配信息， 从而确定出 第一终端设备所使用的网络资源。
作为一个示例， 第二终端设备可以在整个时隙资源、 频率资源或码道 资源上进行搜索， 如果在某个时隙、 频率或码道上可以通过第一终端设备 接入网络中的目标设备， 则该时隙、 频率或码道为第一终端设备所使用的 网络资源。
402 ,第二终端设备根据该网络资源通过第一终端设备接入目标设备。 可选地，第二终端设备根据该网络资源通过第一终端设备接入目标设 备， 包括：
第二终端设备根据第一终端设备所使用的网络资源确定信道与网络 资源的对应关系， 该对应关系用于指示同步信道、 广播信道或接入信道所 使用的网络资源；该第二终端设备根据信道与网络资源的对应关系通过第 一终端设备接入目标设备。
作为一个示例，第二终端设备确定了第一终端设备在协助第二终端设 备接入到目标设备所使用的时隙资源、 频率资源或码道资源后， 可以进一 步对该时隙资源、 该频率资源或该码道资源进行检测， 并确定信道与这些 时隙资源、 频率资源或码道资源的对应关系， 并根据该对应关系与第一终 端设备建立连接， 通过第一终端设备接入到网络中的目标设备。 第二终端 设备可以根据该对应关系通过第一终端设备接入到目标设备中。
在现有技术中， CF UE通过自身的能力以竟争方式获取用于协助 AC UE 接入网络中的目标设备的网络资源，由于不是由基站统一调度和分配的网 络资源， CF UE占用的网络资源可能并不能够协助 AC UE接入到网络中或者 由于自身能力较弱导致无法占用足够的网络资源为第二终端设备服务。应 用本发明实施例提供的技术方案，基站为第一终端设备分配用于协助第二 终端设备接入目标设备的网络资源，该网络资源不是由第一终端设备通过 自身的能力通过竟争的方式获得的，由于基站本身具有对其所服务的终端 设备具有调度功能， 基站很容易获知哪些网络资源可用， 哪些网络资源可 以更高效地协助第二终端设备接入到网络中， 因而可以避免由于 CF UE通 过竟争占用网络资源而导致的资源浪费的问题，从而节省了网络资源并提 高了第二终端设备的用户体验。
本发明实施例还提供如图 5所示的一种接入网络中的目标设备方法的 系统交互示意图， 在该示例中， 第一终端设备为 CF UE , 第二终端设备为 AC UE , 该示例包括以下内容。
501 , 第一终端设备 ( UE1 )在确定作为 CF UE并需要为第二终端设备 (UE2)提供接入网络中的目标设备中的目标设备情况下， 第一终端设备向 基站发送请求信息， 该请求信息用于请求基站分配网络资源， 该基站分配 的网络资源用于第二终端设备通过第 ―终端设备接入目标设备。 可选地， 该网络资源包括时隙资源、 频率资源和 /或码道资源。
502 , 基站将网络资源的分配信息通过广播或 RRC信令发送给第一终 端设备。 当然， 基站也可以通过其他方式将网络资源的分配信息发送给第 一终端设备。 可选地， 如果基站预先获知第二终端设备将通过第一终端设 备接入网络中的目标设备，基站可以直接将网络资源的分配信息通过广播 或信令发送给第一终端设备，而不需要第一终端设备向基站请求分配网络 资源后， 基站再为第一终端设备分配上述网络资源， 这种情况下 501是可 选地。
503 , 第一终端设备根据接收到的网络资源的分配信息确定基站分配 的网络资源， 例如时隙、 频率或码道等， 并根据网络资源在 SCH、 BCH和 RACH等信道上发送数据， 该数据可以包括第一终端设备根据上述网络资 源在 SCH上发送的同步数据、 根据上述网络资源在 BCH上发送的广播数 据，以及在该广播数据中包含的用于指示第一终端设备根据上述网络资源 所对应的 RACH。
504 , 第二终端设备通过搜索或监听确定网络资源， 并在搜索监听的 过程中根据上述网络资源确定信道与网络资源的对应关系，并根据信道与 网络资源的对应关系与第一终端设备的 SCH进行信道同步，确定第一终端 设备使用网络资源所对应的 BCH ,并从 BCH读取使用上述网络资源所对应 的 RACH。
505 , 第二终端设备根据上述网络资源所对应的 R A C H通过第一终端 设备目标设备。
在现有技术中， CF UE通过自身的能力以竟争方式获取用于协助 AC UE 接入网络中的目标设备的网络资源，由于不是由基站统一调度和分配的网 络资源， CF UE占用的网络资源可能并不能够协助 AC UE接入到网络中或者 由于自身能力较弱导致无法占用足够的网络资源为第二终端设备服务。应 用本发明实施例提供的技术方案，基站为第一终端设备分配用于协助第二 终端设备接入目标设备的网络资源，该网络资源不是由第一终端设备通过 自身的能力通过竟争的方式获得的，由于基站本身具有对其所服务的终端 设备具有调度功能， 基站很容易获知哪些网络资源可用， 哪些网络资源可 以更高效地协助第二终端设备接入到网络中， 因而可以避免由于 CF UE通 过竟争占用网络资源而导致的资源浪费的问题，从而节省了网络资源并提 高了第二终端设备的用户体验。
再一方面， 本发明实施例提供了一种基站， 该基站可以为如图 2-5任 意一个所示的方法实施例中的基站， 如图 6所示本发明实施例中基站的结 构示意图， 包括：

在现有技术中， CF UE通过自身的能力以竟争方式获取用于协助 AC UE 接入网络中的目标设备的网络资源，由于不是由基站统一调度和分配的网 络资源， CF UE占用的网络资源可能并不能够协助 AC UE接入到网络中或者 由于自身能力较弱导致无法占用足够的网络资源为第二终端设备服务。应 用本发明实施例提供的基站、 第一终端设备和第二终端设备， 基站为第一 终端设备分配用于协助第二终端设备接入目标设备的网络资源，该网络资 源不是由第一终端设备通过自身的能力通过竟争的方式获得的，由于基站 本身具有对其所服务的终端设备具有调度功能，基站很容易获知哪些网络 资源可用， 哪些网络资源可以更高效地协助第二终端设备接入到网络中， 因而可以避免由于 C F U E通过竟争占用网络资源而导致的资源浪费的问 题， 从而节省了网络资源并提高了第二终端设备的用户体验。 再一方面， 本发明实施例还提供了一种基站， 如图 9所示基站的结构 示意图， 包括： 处理器 901、 通信接口 902、 存储器 903、 总线 904。 处理器 901、 通信接口 902和存储器 903通过总线 904连接在一起。 存储器 903用于 储存计算机程序代码， 该程序代码包括：
