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作出创造 性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
在本实施例中， 以 LTE ( Long Term Evolut ion, 长期演进）通信系统为 例进行描述说明，在该系统中，可以有基站（Evolve Node Base s ta t ion , eNB )、 多个中继节点 （Re lay node , RN )及多个用户终端 （User equi ment , UE )， 其中， 当然用户终端（ User equi pment , UE )也可以包括移动终端。 在本实施 例中， 有三种通信方式， 第一种方式为： UE 可以和基站直接进行通信， 不需 要 RN进行协作， 第二种方式为： UE可以先与 RN通信，再通过 RN与基站通信， 第三种方式为： UE与基站直接通信的同时， RN对该 UE与基站的通信进行监控 或侦听， 当 UE与基站之间的通信信道质量不好， 或很差的时候， RN协作 UE 与基站之间的通信。 在本实施例中， RN可以监控多个 UE。 在本实施例中， 若当前通信网络， 只有 RN需要接入基站时， RN有两种接 入基站的方式，一种是基于非竟争随机接入基站， 另一种是基于竟争随机接入 基站， 而在基于竟争随机接入基站的过程中， 进一步包括初始接入基于竟争随 机接入基站和非初始接入基于竟争随机接入基站。
若当前通信网络，有 RN和 UE同时需要接入基站时，基站需要对请求接入 基站的对象进行识别， 并采用系统预定的优先接入原则选择接入基站的对象。 当然， 其中， UE也具有跟 RN—样的接入基站的方式， 只是当 UE跟 RN同时接 入时， 在接入的过程中， 基站需要判断识别， 对 UE和 RN之间进行选择。
在本实施例中， RN在基于非竟争随机接入的方式下， 此时， 基站已知 RN 的信息， 并且， 这种接入方式， 是先由基站向 RN发送指派随机接入序列， 再 由 RN 发送随机接入请求消息， 再由基站发送随机接入响应， 即基站通过 RA-RNTI ( Random Access Radio Network Temporary Identifier, 随机接入 无线网络临时标识）加扰 PDCCH (Physical Downlink Control Channel, 物 理下行控制信道）向 RN发送随机接入响应 ( Random Access Response, RAR )。 在本实施例中， RAR 可以包括 TEMPORARY C-RNTI ( Cell Radio Network Temporary Identifier )和 UL Grant信息。 此时， 表明接入完成。
在本实施例中，在基于竟争随机接入基站的方式中， 由 RN或 UE主动向基 站发起接入请求， 再由基站对发起接入请求的对象进行识别确认， 即确认发起 接入请求的对象是 RN还是 UE。 再由基站根据优先接入原则选择接入请求的对 象。
图 1 为本发明实施例的应用于请求接入基站的接入方法的第一种实施例 的流程图。 在本实施例中， 图 1为初始接入基于竟争随机接入基站的流程图。 在本实施例中，在中继节点初始接入基站前，基站无法得知请求接入基站的对 象是 RN还是 UE。
步骤 S100， 基站接收 RN发送的随机接入请求消息。 在本实施例中， 该随 机接入请求消息包括 Preamble序列。 在本实施例中， 基站可以接收到多个 RN 发送的随机接入请求。
步骤 S102，基站返回随机接入响应至 RN。在本实施例中，基站通过 RA-RNTI ( Random Access Radio Network Temporary Identifier, 随机接入无线网各 ι|έ时标只）力口 4尤 PDCCH (Physical Downlink Control Channel, 物理下行控 制信道） 向 RN发送随机接入响应 ( Random Access Response, RAR )。 在本实 施例中， RAR可以包括 TEMPORARY C-RNTI 和 UL Grant信息。
在本实施例中， 当 RN接收到基站发送的随机接入响应后， 生成上行调度 接入 ( Scheduled Up link transmission ) 消息， 上行调度接入消息中包括 RRC Connection Request消息， 并将 RRC Connect ion Reques t消息中的 space 位设置为 1， 及根据 UL Grant (Up Link Grant, 上行链路指示）消息指示发送 给基站。 在本实施例中， 将 RRC (Radio Resource Control, 无线资源控制） Connection Request消息中的 space位设置为 1, 是用来标识清求接入基站的 对象是中继节点， 并用于基站区别请求接入基站的对象是 RN还是 UE。
步骤 S104， 基站接收到中继节点发送的上行调度接入消息。
步骤 S106， 基站确定该上行调度接入信息中的 RRC Connection Request 消息中的 space位的值。在本实施例中， 当基站确定该上行调度接入信息中的 RRC Connection Request 消息中的 space位的值为 1时， 可以确定当前清求 接入基站的对象是中继节点。 在本实施例中， RRC Connection Request 消息 可以包括 RN的 NAS ( Non-Acces s St ra tum, 非接入层）标识。 当然， 在基站 的内部可以将识别的原则进行设置， 比如， 可以当上行调度接入信息中的 RRC Connect ion Reques t消息中的 space位的值为 1时， 设置清求接入基站的对 象为 RN， 也可以设置请求接入基站的对象为 UE， 也可以当上行调度接入信息 中的 RRC Connect ion Reques t消息中的 space位的值为 0时， 设置倚求接入 基站的对象为 RN， 也可以设置请求接入基站的对象为 UE， 当然， 在设置原则 时， 基站需要与 RN和 UE保持相同的标准原则。
步骤 S108， 基站根据优先接入原则确定将中继节点接入基站。 在本实施 例中， 基站的优先接入原则包括优先选择 RN或优先选择 UE。 当然， 基站可以 根据当前的通信网络状况来 将其中的一个原则作为当前的选择原则。 当然， 基站可以对当前的选择原则进行调整，以满足通信网络的需求。在本实施例中， 以优先选择 RN作为第一个优先考虑的原则。 因此， 在本实施例中， 若基站当 前优先选择 R 时， 基站会将该 RRC Connect ion Reques t 消息中 i n i t i a 1 RN- 1 den t i t y作为解决接入的消息， 即将 R 的 AS标识作为解决接入 的消息。 在本实施例中， 解决接入的消息也可以称之为碰撞处理消息。 通过 Temporary C-RNTI 发送 RN。 在本实施例中， 当基站通过 Temporary C-RNTI 将解决接入的消息发送给 RN时， 就可以认为是基站同意该 RN接入基站。在本 实施例中， 基站还将该 RN作为接入成功的 RN进行管理， 即保存接入成功的 R 的 C- RNTI。
当然， 在 RN接收到该通过 Temporary C-RNTI发送的解决接入的消息后， 可以通过 Temporary C-RNTI 解调该解决接入的消息， 取出其中的 RN的 NAS 标识与自己本身的 NAS标识进行比对，以确定自己本身是否成功接入。若相同， 则确定自己本身成功接入该基站。 当 RN 确定自己成功接入基站后， 将 TEMPORARY C- RNTI设置为 C-RNTL
本实施例提供的技术方案， 若 RN和 UE处于初始接入基站时， 当 RN请求 接入基站时， 当接收到基站返回的随机接入响应后，将需要发送基站的上行调 度接入消息中的 RRC Connect i on Reque s t消息中的 s ace位设置为 1， 以用 于标识请求接入基站的对象是中继节点，基站通过确定该上行调度接入信息中 的 RRC Connection Request消息中的 space位的值， 来识另确认当前清求接 入的对象是否为 RN， 当确定为 RN时， 根据优先原则确定 RN接入基站， 从而 可以让基站识别请求接入的对象， 并当识别接入的对象后， 可以合理的选择请 求接入的对象，从而可以避免基站盲目的同意接入基站的请求， 并可以减少大 量的 UE和 RN同时接入基站时， 基站的工作负载。

在本实施例中，基站 12包括接收单元 120、识别单元 121、存储单元 122、 管理单元 123及发送单元 124。
在本实施例中，接收单元 120用于接收请求接入基站的对象发送的随机接 入请求消息。 在本实施例中， 请求接入基站的对象包括 RN和 UE， 即接收 RN 或 UE发送的随机接入请求消息。
发送单元 124用于当接收单元 120接收到随机接入请求消息时，向发送随 机接入请求消息的对象发送随机接入响应。 在本实施例中， 发送单元 124 向 R 或 UE发送随机接入响应。
接收单元 120还用于当发送单元 124发送后随机接入响应后，接收请求接 入基站的对象发送的上行调度接入消息。
若 RN和 UE是初始请求接入基站时， RN发送的上行调度接入消息中包括 RRC Connection Request消息， RRC Connection Request消息中的 space 位设置为 1， UE发送的上行调度接入消息中包括 RRC Connection Request消 息， 并将 RRC Connection Request消息中的 space位设置为 0。
识别单元 121用于根据该上行调度接入信息中的 RRC Connection Request 消息中的 space位的值， 来识别确定请求接入基站的对象。 在本实施例中， 当 识另 'J该上行调度接入信息中的 RRC Connection Request消息中的 space位的 值为 1 时， 确定当前请求接入基站的对象是 RN。 在本实施例中， 当识别该上 行调度接入信息中的 RRC Connection Request消息中的 space位的值为 0时， 确定当前请求接入基站的对象是 UE。
管理单元 123用于当识别单元 121识别确定请求接入基站的对象后，根据 优先接入原则选择请求接入基站的对象接入基站。在本实施例中，基站的优先 接入原则包括优先选择 R 或优先选择 UE。 在本实施例中， 以优先选择 R 作 为第一个优先考虑的原则。具体的实施过程可参见图 1、图 5中的实施例描述。
存储单元 122用于当管理单元 123选择请求接入基站的对象接入基站后， 将选择的接入基站的对象的 C-RNTI进行保存。在本实施例中，若管理单元 123 选择 R 接入基站， 则存储单元 122保存该 RN的 C-RNTI。 若管理单元 123选 择 UE接入基站， 则存储单元 122保存该 UE的 C-RNTI。 当然， 存储单元 122 还可以将接入基站的 RN和 UE进行分类存储， 即， 将接入基站的多个 RN作为 一类进行存储， 将接入基站的多个 UE作为另一类进行存储。
本实施例提供的技术方案， 若 RN和 UE处于初始接入基站时， 当 RN和 UE 请求接入基站时， 当 RN和 UE接收到基站返回的随机接入响应后， RN将需要 发送基站的上行调度接入消息中的 RRC Connection Request 消息中的 space 位设置为 1， 以用于标识请求接入基站的对象是中继节点， UE将需要发送基站 的上行调度接入消息中的 RRC Connection Request消息中的 space位设置为 0, 以用于标识请求接入基站的对象是 UE; 基站通过确定该上行调度接入信息 中的 RRC Connection Request消息中的 space位的值， 来识另确认当前清求 接入的对象是为 RN还是 UE， 当确定为 RN或 UE时， 根据优先原则确定 RN接 入基站， 从而可以让基站识别请求接入的对象， 并当识别接入的对象后， 可以 合理的选择请求接入的对象， 从而可以避免基站盲目的同意接入基站的请求， 并从而可以避免当 RN和 UE同时请求接入时， 造成的混乱次序。
若 RN和 UE是非初始请求接入基站时， 当 RN接收到基站发送的随机接入 响应后， 生成上行调度接入 ( Scheduled Up 1 ink transmission ) 消息， 该消 息中包括 RN的 C-RNTI。由于此时， RN曾经接入过基站，此次为重新接入基站， 故， 将 RN的 C-RNTI根据 ULGrant指示发送给基站。 同时， 当 UE接收到基站 发送的随机接入响应后， 生成上行调度接入 ( Scheduled Up link transmission)消息， 该消息中包括 UE的 C-RNTI。 由于此时， UE曾经接入过 基站， 此次为重新接入基站， 故， 将 UE的 C-RNTI根据 UL Grant指示发送给 基站。
识别单元 121还用于识别确定请求接入基站的对象是否曾经接入该基站。 在本实施例中，识别单元 121将 RN的该上行调度接入信息中 C-RNTI与存储单 元 122保存的 RN的 C-RNTI进行匹配， 来确定该 RN是否曾经接入该基站。 若 上行调度接入信息中 C-RNTI与存储单元 122保存的 RN的 C-RNTI相同， 则说 明该 RN曾经接入过该基站。在本实施例中，识别单元 121将 UE的该上行调度 接入信息中 C-RNTI与存储单元 122保存的 UE的 C-RNTI进行匹配， 来确定该 UE是否曾经接入该基站。 若 UE的上行调度接入信息中 C-RNTI与保存的 UE的 C-RNTI相同， 则说明该 UE曾经接入过该基站。
管理单元 123还用于当识别单元 121识别确定请求接入基站的对象是否曾 经接入该基站后，根据优先接入原则选择请求接入基站的对象接入基站。在本 实施例中， 基站的优先接入原则包括优先选择 RN或优先选择 UE。 在本实施例 中， 以优先选择 RN作为第一个优先考虑的原则。 具体的实施过程可参见图 3 和图 8中的实施例描述。
本实施例提供的技术方案， 若 RN和 UE处于非初始接入基站时， 当 RN和
UE请求接入基站时， 当接收到基站返回的随机接入响应后， RN将需要发送基 站的上行调度接入消息中的 RRC Connec t ion Reques t消息包括 RN的 C-RNTI , 以用于确定该 RN是否曾经接入该基站， UE将需要发送基站的上行调度接入消 息中的 RRC Connect ion Reques t消息包括 UE的 C-RNTI , 以用于确定该 RN是 否曾经接入该基站； 若确定该 RN曾经接入该基站， 选择该 RN接入该基站， 从 而可以让基站识别请求接入的对象， 并当识别接入的对象后， 可以合理的选择 请求接入的对象，从而可以避免基站盲目的同意接入基站的请求， 并从而可以 避免当 RN和 UE同时请求接入时， 造成的混乱次序。
图 13为本发明实施例的中继节点的结构图。 在本实施例中， 中继节点 13 包括接收单元 130、 处理单元 131及发送单元 132。
当 RN是初始请求接入基站时：
发送单元 132用于发送随机接入请求消息至基站。当基站接收到请求接入 基站的对象发送的随机接入请求消息后， 即接收 RN发送的随机接入请求消息 后， 会发送随机接入响应。
接收单元 130用于接收基站发送的随机接入响应。
处理单元 131用于当接收单元 130接收到基站发送的随机接入响应后，生 成上行调度接入消息， 该消息中包括 RRC Connection Request消息， 并将 RRC Connection Request 消息中的 space 位设置为 1。 在本实施例中， 将 RRC Connection Request消息中的 space位设置为 1, 是用来标识清求接入基站的 对象是中继节点， 并用于基站区别请求接入基站的对象是 RN。
发送单元 132还用于将处理单元 131 生成的上行调度接入消息发送至基 站。 在本实施例中， 当基站识别确定请求接入基站的对象为 RN， 并选择该 RN 接入基站时， 基站通过 Temporary C-RNTI将解决接入的消息发送给 RN时， 就 可以认为是基站同意该 RN接入基站。
接收单元 130还用于基站通过 Temporary C-RNTI发送的解决接入的消息。 处理单元 131还用于通过 Temporary C-RNTI解调该解决接入的消息， 取出其 中的 RN的 NAS标识与自己本身的 NAS标识进行比对， 以确定自己本身是否成 功接入。 若相同， 则确定自己本身成功接入该基站。 当 RN确定自己成功接入 基站后， 将 TEMPORARY C-RNTI设置为 C_RNTI。 当 RN是非初始请求接入基站时：
处理单元 131还用于当接收单元 130接收到基站发送的随机接入响应后， 生成上行调度接入消息， 该消息中包括 RN的 C-RNTI。 在本实施例中， 基站将 该上行调度接入信息中 C-RNTI与保存的 RN的 C-RNTI进行匹配， 来确定该 RN 是否曾经接入该基站。 若上行调度接入信息中 C-RNTI与保存的 RN的 C-RNTI 相同， 则说明该 RN曾经接入过该基站。基站通过 C-RNTI发送解决接入的消息 至 RN。
本实施例提供的技术方案， 若 RN处于初始接入基站时， 当 RN请求接入基 站时， 当接收到基站返回的随机接入响应后，将需要发送基站的上行调度接入 消息中的 RRC Connect ion Reques t消息中的 space位设置为 1， 以用于标识 请求接入基站的对象是中继节点， 使基站通过确定该上行调度接入信息中的 RRC Connect ion Reques t 消息中的 s pace位的值， 来识别确认当前倚求接入 的对象是否为 RN， 当确定为 RN时， 根据优先原则确定 RN接入基站， 从而可 以让基站识别请求接入的对象， 并当识别接入的对象后， 可以合理的选择请求 接入的对象， 从而可以避免基站盲目的同意接入基站的请求。
本实施例中提供的技术方案， 当 RN处于非初始接入基站时， 当 RN请求 接入基站时， 当接收到基站返回的随机接入响应后，将需要发送基站的上行调 度接入消息中的 RRC Connect ion Reques t消息包括 RN的 C-RNTI , 以用于使 基站确定该 RN是否曾经接入该基站， 若确定该 RN曾经接入该基站， 选择该 R 接入该基站， 从而可以让基站识别请求接入的对象， 并当识别接入的对象 后， 可以合理的选择请求接入的对象，从而可以避免基站盲目的同意接入基站 的请求。 本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程， 是可以通过计算机程序来指令相关的硬件来完成，所述的程序可存储于一计算 机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。 其中，所述的存储介质可为磁碟、光盘、只读存储记忆体（Read-Only Memory, ROM )或随机存储记忆体 ( Random Access Memory, RAM )等。
