步骤 1 3、 根据无线承载建立预处理的结果, 所述中继站生成第二无线承 载建立消息;
步骤 14、所述中继站向对应的用户设备发送所述第二无线承载建立消息, 通知所述用户设备建立接入链路上的无线承载。 由上可以看出, 本发明实施例一所述的方法, 当系统中存在中继站的时 候, 由所述中继站根据由基站发送的第一无线承载建立消息, 进行无线承载 建立预处理; 根据该预处理的结果生成第二无线承载建立消息并将该消息发 送给用户设备, 使得用户设备能够根据第二无线承载建立消息建立无线承载。 因此, 利用本发明实施例的技术方案, 使得在引入中继站的情况下, 能够建 立基站与用户设备端到端无线承载的建立。
下面分别结合不同的应用场景详细描述一下本发明实施例所述的无线承 载的建立方法的实现过程。
在实施例二中, 以根据用户设备的业务请求, 直接为用户设备建立无线 承载为例。
如图 2所示, 本发明实施例二所述的无线承载的建立方法包括如下步骤: 步骤 21、 用户设备通过中继站(Re lay S ta t ion, RS )、 eNB 向核心网发 送业务请求。
例如,用户设备向中继站发送业务请求,中继站将该业务请求透传至 eNB , 而 eNB将该业务请求转发至核心网, 从而实现用户设备向核心网发送业务请 求。
步骤 22、 所述 eNB根据所述业务请求, 生成第一无线承载建立消息。 在步骤 22中, eNB并不对业务请求的相关特性进行判断, 仅为接收到业 务请求就触发生成第一无线承载建立消息, 即生成无线承载建立消息以该业 务请求为触发条件, 但是与其具体内容无关。
步骤 23、 所述 eNB向 RS发送第一无线承载建立消息。 该第一无线承载建 立消息例如包括无线承载配置消息, 其中无线承载配置消息例如包括: UE、
RS、 CN、 传输信道、 物理信道、 无线资源等配置参数, 或者上述配置参数的 任意组合。
步骤 24、 所述中继站根据所述第一无线承载建立消息, 进行无线承载建 立预处理。 具体例如包括: 中继站进行中继链路上无线承载建立的相关配置。 例如还可以包括, 获取需要建立的接入链路上的无线承载的参数等。
步骤 25、 所述中继站根据预处理结果, 生成第二无线承载建立消息。 在 所述第二无线承载建立消息中可包括无线承载配置消息, 例如 UE、 CN、 传输 信道、 物理信道、 无线资源等配置参数, 或者上述配置参数的任意组合。
步骤 26、 所述中继站根据第一无线承载建立消息, 向所述基站发送第一 无线 7 载建立完成消息。
步骤 27、 所述中继站向所述用户设备发送第二无线承载建立消息, 通知 所述用户设备建立无线承载。
步骤 28、 所述用户设备根据所述第二无线承载建立消息, 进行接入链路 上无线承载建立的相关配置。
步骤 29、 所述用户设备向所述中继站发送第二无线承载建立完成消息, 无线承载建立过程结束。
在实施例二中, 步骤 26还可以在步骤 24或者步骤 29后执行。
由实施例二可以看出, 在实施例二中, 对于每个用户设备的业务请求, 中继 站都是为其建立新的无线承载。 也就是说, 当系统中存在中继站的时候, 由 所述中继站根据由基站发送的第一无线承载建立消息, 进行无线承载建立预 处理。 然后根据该预处理的结果生成第二无线承载建立消息并将该消息发送 给用户设备, 使得用户设备能够根据第二无线承载建立消息建立无线承载。 因此, 利用本发明实施例的技术方案, 使得在引入中继站的情况下, 能够建 立基站与用户设备端到端无线承载的建立。
并且, 由实施例二可以看出, 它是对于每个用户设备的业务请求, 都是 由中继站为其建立新的无线承载, 而无论之前在中继链路上是否已存在承载 有与用户设备发起的业务请求相同的业务的无线承载, 例如与该用户设备的 业务请求具有相同 QoS ( Qua l i ty of Serv i ce , 服务质量) 的无线承载。 在实 施例三、 实施例四中, 将以不同用户设备的相同的业务请求为基础, 为用户 设备建立无线承载, 其中相同的业务请求是指具有相同业务特征的业务请求, 相同业务特征例如为具有相同的 QoS , 下述各实施例中不再赘述。
如图 3所示, 本发明实施例三的无线承载的建立方法包括如下步骤: 步骤 31、 用户设备通过 RS、 eNB向核心网发送业务请求。
此步骤的实现过程可以参照实施例二中的步骤 21。
步骤 32、 基站或核心网根据所述业务请求判断中继链路上是否存在与所 述用户设备的业务请求具有相同 QoS 的无线承载。 当由核心网进行判断时, 核心网会将判断结果发送给所述基站。
当不存在与该用户设备的业务请求具有相同 QoS 的无线承载时, 执行步 骤 33-40; 当存在与所述用户设备的业务请求具有相同 QoS的无线承载时,执 行步骤 41-49。
步骤 33、 基站根据核心网的判断结果或者根据其自身的判断结果, 生成 第一无线承载建立消息。
步骤 34、 中继站接收由基站发送的第一无线承载建立消息, 所述第一无 线承载建立消息中包括为至少一个用户设备建立无线承载的要求以及为所述 用户设备分配的资源。在此实施例中,是基于在步骤 34前进行一个判断步骤。 该判断步骤具体为, 在特定条件下, 不同用户设备发起的业务请求是否相同。 其中, 该特定条件例如为一段时间, 即该判断步骤例如为, 判断在一定时间 内, 不同用户发起的业务请求是否相同。 因此, 根据所述第一无线承载建立 消息中所包含的内容不同, 可分为以下两种情况:
情况一: 当所述的第一无线承载建立消息中包括为一个用户设备建立无 线承载的要求以及为所述用户设备分配的资源时, 基于上述判断步骤中判断 发起业务请求的不同 UE发起的业务请求不相同。 也就是说, 在 eNB或者核心 网判断不同 UE发起的业务请求不相同时, 在 eNB发送给中继站的第一无线承 载建立消息中只包括为一个用户设备建立无线承载的要求以及为该用户分配 的资源。 例如, 当 UE1发起的业务请求为业务请求 1 , 而 UE2发起的业务请求 为业务请求 2 , 且业务请求 1与业务请求 2不相同时, eNB会向中继站发送两 条第一无线承载建立消息, 即第一无线承载建立消息 1 和第一无线承载建立 消息 2。 其中, 第一无线承载建立消息 1中包括为 UE1建立无线承载的要求以 及为 UE1分配的资源; 第一无线承载消息 2中包括为 UE2建立无线承载的要 求以及为 UE2分配的资源。 在下述实施例中类似情况不再赘述。

情况二: 当所述第一无线承载建立消息中包括为至少两个发起相同业务 请求的用户设备建立无线承载的要求以及为所述至少两个用户设备分配的资 源时, 基于上述判断步骤中判断至少两个用户设备发送相同的业务请求。 例 如, 在一段时间内 UE1发起业务请求 1 , UE2也发起业务请求 1 , 则 eNB或者 核心网判断在时间段内, UE1和 UE2发起的业务请求相同, 则 eNB向中继站发 送第一无线承载建立消息 1 ,该消息中包括为 UE1和 UE2建立无线承载的请求, 以及为 UE1和 UE2分配的资源。 此时, 该第一无线承载建立消息具体为复合 无线 载建立消息 (comb ined RB se tup )。 所述复合无线 载建立消息包括 UE、 RS、 CN、 RB、 传输信道、 物理信道、 无线资源等配置参数。 所述的无线 资源例如为, 为所述至少两个用户设备共同分配的资源块。

针对步骤 34中的情况二, 所述中继站进行无线承载建立预处理的过程具 体包括: 中继站首先根据所述复合无线承载建立消息, 进行无线承载建立相 关配置, 与所述基站建立复合无线承载, 然后根据所述复合无线承载建立消 息中所携带的信息, 将为所述各用户设备分配的资源进行分割, 并建立所述 复合无线承载和接入链路上的无线承载的映射表。 该映射表用于表示中继链 路上的无线承载和接入链路上的无线承载之间的对应关系。
步骤 36、 中继站根据预处理结果, 生成第二无线承载建立消息。 在所述 第二无线承载建立消息中包括无线承载配置消息, 例如 UE、 CN、 传输信道、 物理信道、 无线资源等配置参数, 或者上述配置参数的任意组合。
步骤 37、 中继站根据第一无线承载建立消息, 向基站发送第一无线承载 建立完成消息。
针对步骤 34中的情况二, 该第一无线承载建立完成消息可具体为复合无 线 7 载建立完成消息。
步骤 38、 中继站根据建立的映射表, 向对应的用户设备发送所述第二无 线承载建立消息, 通知所述用户设备建立无线承载。
步骤 39、 所述用户设备根据所述第二无线承载建立消息, 建立无线承载。 步骤 40、中继站接收由所述用户设备发送的第二无线承载建立完成消息。 其中, 步骤 37也可放在步骤 36或步骤 4G后执行。

步骤 43、 中继站根据所述无线承载重配置消息, 进行无线承载建立预处 理。
在此实施例中, 当所述无线承载重配置消息中包括为一个用户设备重配 置无线承载的要求时, 此步骤可具体包括:
中继站根据所述无线承载重配置消息, 修改配置参数。 由于存在与所述 用户设备的业务请求具有相同 QoS 的无线承载, 因此, 在为之前的其他设备 建立无线承载时, 就已经建立好了映射表, 所以在此实施例中, 即可更新已 建立的中继链路上的无线承载和接入链路上的无线承载之间的映射表。
当所述无线承载重配置消息中包括为至少两个发起相同业务请求的用户 设备重配置无线承载的要求以及为所述至少两个用户设备分配的资源时, 此 步骤可具体包括:
根据所述无线承载重配置消息, 修改配置参数, 并更新已建立的中继链 路上的无线承载和接入链路上的无线承载之间的映射表。 设备分配一个 id (标识), 然后将该标识填加到所述映射表中。
步骤 44、 中继站根据无线承载建立预处理的结果, 生成第二无线承载建 立消息。

其中, 步骤 45可放在步骤 43后或步骤 48后执行。
在实施例三中, 在不存在与用户设备的业务请求具有相同 QoS 的业务的 时候, 通过映射表的建立, 使得再为后续的其他设备建立无线承载时, 可简 化建立无线承载的过程; 在已存在与用户设备的业务请求具有相同 QoS 的业 务的时候, 通过无线承载重配置消息修改无线承载配置参数、 更新已建立的 映射表的方式为用户设备建立无线承载, 而无需重复无线承载的建立过程, 进一步提高了为用户设备建立无线承载的效率。 如图 4所述, 本发明实施例四建立无线承载的方法包括如下步骤: 步骤 51、 至少两个用户设备(此实施例中为 UE1、 UE2 )通过中继站、 基 站向核心网发送业务请求。

以上的实施例二、 实施例三、 实施例四的方法, 可以称为接入链路、 中 继链路的动态调整方式。 而以下的实施例五将以接入链路的动态调整、 中继 链路的半静态调整方式进行描述。
在实施例五中, 以用户设备发起业务请求而触发无线承载的建立为例进 行描述。
如图 5所示, 本发明实施例五包括如下步骤:

步骤 65、 中继站根据所述映射表, 生成所述第二无线承载建立消息。 步骤 66、 中继站根据第一无线承载建立消息, 向基站发送第一无线承载 建立完成消息。
步骤 67、 中继站向所述用户设备发送所述第二无线承载建立消息, 通知 所述用户设备建立无线承载。

在此步骤中, 若是由核心网判断是否存在与所述第二用户设备的业务请 求具有相同 QoS 的无线承载, 则会将判断结果发送给基站。 然后基站会根据 核心网的判断或其自身的判断, 将判断结果发送给中继站(未图示)。
步骤 61 1、 中继站更新所述映射表, 并为所述第二用户设备生成第二无线 承载建立消息并发送给所述第二用户设备。 即, 对于该用户的该业务请求, 可以使用已经建立好的中继链路上的无线承载。
步骤 612、 重新为所述第二用户设备建立无线承载, 即重复上述过程。 步骤 61 3、中继站接收由所述第二用户设备发送的第二无线承载建立完成 消息。
其中, 上述步骤 66可放在步骤 64后或者步骤 69后执行。 在实施例五中, 首先由中继站根据当前用户设备的业务请求建立一个承 载有多个用户设备的相同业务的复合无线承载, 然后在有新的用户设备的业 务请求时, 当所述新的用户设备的业务请求与当前用户设备的业务请求相同 时, 直接更新已建立的映射表, 不建立新的中继链路上的无线承载, 而是使 用现有的相同业务的无线承载。 否则重新为所述新的用户设备重新建立无线 承载。 通过上述方式, 提高了为用户设备建立无线承载的效率。
此外, 如图 6所示, 本发明实施例六还提供了一种建立无线承载的方法, 包括:
步骤 614、 中继站接收由基站发送的第一无线承载建立消息;

或者, 在步骤 616与 61 7重复执行的过程中, 还可以再次执行步骤 614 和步骤 615。
在本实施例中, 先建立中继站与基站之间的中继链路上的无线承载, 在 建立上述无线承载时, 是基于主要的业务建立的带宽较宽的无线承载。 此后, 在 UE发起业务请求时, 只需判断是否存在相同业务的中继链路的无线承载, 在存在时, 直接使用该中继链路上该相同业务的无线承载, 仅需要再建立接 入链路上的无线承载; 而在不存在相同业务的无线承载时, 需要重新建立一 个带宽较宽的中继链路上的无线承载, 再建立接入链路上的无线承载。
由实施例六的技术方案可以看出, 当系统中存在中继站的时候, 由所述 中继站根据由基站发送的第一无线承载建立消息, 进行无线承载建立预处理; 根据用户设备的业务请求第二无线承载建立消息并将该消息发送给用户设 备, 使得用户设备能够根据第二无线承载建立消息建立无线承载。 因此, 利 用本发明实施例的技术方案, 使得在引入中继站的情况下, 能够建立基站与 用户设备端到端无线承载的建立。 并且, 由于中继链路上的无线承载已经事 先建立, 因此在 UE发起业务请求后, 无需建立新的中继链路上的无线承载, 节省了信令开销和网絡资源。

步骤 74、 中继站根据所述复合无线承载建立消息, 与所述基站建立关于 用户设备的至少一个业务请求的复合无线承载, 也就是说该复合无线承载能 够承载多个用户设备的相同业务, 以保证建立在该中继链路的无线承载能够 在一定时间内保持不变。
步骤 75、 中继站向所述基站发送复合无线承载建立完成消息。
步骤 76、 中继站生成第二无线承载建立消息。 具体包括: 由中继站根据 接收到的基站或核心网关于否存在与所述用户设备的业务请求具有相同 QoS 的复合无线承载的判断结果进行以下方式的处理。
若存在, 则由中继站更新已建立的复合无线承载和接入链路上无线承载 之间的映射表, 并为所述用户设备生成第二无线承载建立消息。 更新所述映 射表的过程可包括: 为所述复合无线承载和接入链路上的无线承载建映射表, 并将为该用户设备分配的 id添加到映射表中。 若不存在, 则由中继站则重新 为所述新的用户设备建立复合无线承载。
同样, 在此步骤中, 若是由核心网判断是否存在与所述第二用户设备的 业务请求具有相同 QoS 的无线承载, 则会将判断结果发送给基站。 然后基站 会根据核心网的判断或其自身的判断, 将判断结果发送给中继站(未图示)。
步骤 77、 中继站根据所述映射表, 向用户设备发送第二无线承载建立消 息。
步骤 78、 用户设备根据所述第二无线承载建立消息, 建立无线承载。 步骤 79、中继站接收由所述用户设备发送的第二无线承载建立完成消息。 其中, 步骤 75可放在步骤 74后或步骤 79后执行。
进一步的, 在其他用户设备发起业务请求时, 基站或者核心网判断在中 继链路上已经存在的复合无线承载中, 是否有与该业务请求相同的业务。 如 果有, 则向中继站发送第一无线承载建立消息, 使得中继站与该基站使用中 继链路上已经存在的具有与该业务请求相同业务的无线承载, 并由中继站修 改相应的映射表。 如果没有, 则向中继站发送第一无线承载建立消息, 使得 中继站与该基站建立关于该业务请求的新的复合无线承载, 并由中继站建立 新的映射表。
由上可以看出, 当系统中存在中继站的时候, 由所述中继站根据由基站 接收到的第一无线承载建立消息, 进行无线承载建立预处理, 并根据处理结 果生成第二无线承载建立消息, 以使得用户设备能够根据所述第二无线承载 建立消息建立无线承载。 因此, 利用本发明实施例的技术方案, 使得在引入 中继站的情况下, 能够建立基站与用户设备端到端无线承载的建立。
