Description

终端多连接的管理方法、 装置和系统
技术领域
本发明涉及通信领域, 尤其涉及一种终端多连接的管理方法、 装置和系 统。
背景技术
图 1为相关技术中长期演进系统(LTE, Long Term Evolution ) 的总体 架构示意图,如图 1所示, LTE架构包括(部分未示出):移动管理实体(MME, Mobility Management Entity ) , 月良务网关 ( SGW, Serving GetWay ) , 用户 设备或称为终端 (UE, User Equipment )和基站(eNodeB, 简称为 eNB )之 间是 UU接口, eNB和 MME之间是 S 1 -MME ( SI for the control plane )接口, eNB和 SGW之间是 Sl-U接口, eNB之间是 X2接口。
终端建立呼叫的过程, 包括建立 UE和 eNB之间控制面链路和用户面链 路, 以及 eNB和核心网 (CN )之间的控制面链路和用户面链路的过程。 其 中, eNB与核心网的连接上的不同业务的用户面 GTP-U数据釆用演进无线 接入承载 (ERAB, E-UTRAN Radio Access Bearer )来承载, 控制面是通过 eNB与位于核心网的 MME之间的连接来 载; 而 eNB与 UE之间的用户面 的连接釆用若干数据无线承载(DRB, Data Radio Bearer )来承载, 控制面的 连接釆用若干信令无线承载(SRB, Signaling Radio Bearer )来承载。
为了提高用户的通信体验,尤其对于提高用户设备的吞吐量和移动性能, 目前很多运营商和设备商都倾向于寻求一种新的技术方案, 双连接 /多连接 (以下统称双连接)就是其中之一。 双连接是指用户设备可以同时使用至少 两个不同的网络节点的资源, 这至少两个不同的网络节点及其在双连接中所 发挥的功能可以不依赖于网络节点的功能特征, 比如这至少两个不同的网络 节点可以均为传统宏节点或者均为低功率节点, 也可以是一个为宏节点一个 为低功率节点。 考虑低功率节点可能会较多部署在有宏节点覆盖的热点地区 和室内覆盖区域的特征, 用户设备同时使用宏节点和低功率节点的资源的双 连接方案可以预见会大力提高用户通信体验, 满足新的移动需求。 随着双连 接方案的出现, 用户设备需要从目前只能使用一个网络节点的资源扩展到可 以使用两个甚至多个网络节点的资源, 或者说用户设备需要从目前只能连接 至一个网络节点扩展到可以连接到两个甚至多个网络节点, 势必会对连接基 站的管理提出新的挑战, 需要寻求新的连接管理方案。 发明内容

本发明的较佳实施方式
双连接方案的出现, 用户设备从目前只能使用一个网络节点的资源扩展 到可以使用两个甚至多个网络节点的资源, 或者说用户设备从目前只能连接 至一个网络节点扩展到可以连接到两个甚至多个网络节点, 势必会对连接基 站的管理提出新的挑战, 需要寻求新的连接管理方案。
为了解决上述问题,本发明的实施例提供了一种终端多连接的管理方法、 装置和系统。 下文中将结合附图对本发明的实施例进行详细说明。 需要说明 的是, 在不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互任 意组合。
图 2是两种基本的多流架构原理图, 基本上多流可以分为两大类, 一大 类是多流网关, 即在多流网关将下行数据分成多个数据流,分发到多个基站, 然后由终端汇聚来自各个基站的数据, 上行则相反, 由终端发送数据至多个 基站, 基站转发到多流网关, 最终由多流网关汇聚, 其中多流网关可以是核 心网和基站之间的一个网元, 也可以由核心网的网关兼任; 另外一大类是则 是由其中的一个基站将下行来自核心网的数据分发到多个基站, 终端汇聚来 自这些基站的数据, 上行则是由终端发送数据到多个基站, 所有的基站将数 据发送至汇聚基站, 由该基站统一汇聚数据发送到核心网, 即由其中的一个 基站承担多流网关的功能。
在所有的多流架构中, 按基站的功能又分为主基站和辅基站。 主基站和 终端之间接口有完整的控制面和用户面的协议栈, 和普通基站功能一致, 可 以单独工作。 而辅基站与终端之间的接口则可以有两种选择, 选择一为辅基 站和终端之间只有用户面接口, 所有的控制面信令通过主基站发送; 选择二 是辅基站和终端之间也有控制面接口, 可以进行控制信令的直接通讯。 本发 明实施例将对这两种选择都明确多连接的建立过程。
多连接的基站制式对本发明实施例没有影响, 即可以是 LTE FDD, LTE TDD, WCDMA, TD-SCDMA, GSM甚至 wifi, 唯一的限制是需要多个基站之 间是可以互操作的。 另外对于多个基站的类别也不受限制, 可以是宏基站, 微基站, 热点。 终端同时连接多个基站的覆盖之间应该是由重叠或者部分重 叠的。
本发明的实施例一:
本发明实施例提供了一种终端多连接的管理方法。 本发明实施例中, 以 管理设备为独立的多流网关、 源基站为基站 1、 其他基站为基站 2为例, 基 站 1控制所述终端与基站 2建立连接, 多流网关在所述终端建立起与基站 2 的连接后, 将所述终端传输数据的路径更新为通过基站 1和基站 2。
终端与基站 1上的小区 1建立了连接。 基站 1根据算法决策触发需要对 该终端新添加一个基站进行多连接传输。 算法决策可以有多种可能性, 如终 端上报测量报告, 发现一个新的小区满足某一个信号质量门限, 如果该终端 是有多连接能力的终端, 明确该基站 1和待添加基站 2也可以实施多连接, 则基站 1可以触发添加基站 2—起和终端进行多连接传输。 另外一种典型的 算法或者基站 1根据基站自身的负载情况出发的负载均衡的需求, 在确认终 端处于基站 2下的小区覆盖范围内后 (如同覆盖小区或者终端的测量反馈) 以及各基站和终端的多连接能力, 可以触发将部分数据均衡至基站 2 , 一起 和终端进行多连接传输。 以上只是两种的典型的算法触发条件, 仅用于方案 完整性描述, 具体取决于各个基站的实现, 本发明实施例对触发的原因并没 有依赖关系, 所以不做限制, 之后的本发明的其他实施例也不再复述。
使用本发明实施例提供的终端多连接的管理方法实现终端建立多个数据 传输路径的流程如图 3所示, 包括:
步骤 301 :基站 1发送基站添加请求给基站 2。基站添加请求中会携带必 要的源侧信息用于在基站 2侧准备多连接传输。 所述源侧信息包含以下信息 的任一或任意多种: 所述终端在所述源基站的全部或者部分上下文信息、 所 述终端的能力信息、 所述终端在所述源基站或者核心网的信令连接信息和辅 助信息。 具体的, 携带的源侧信息包括不限于: 终端在基站 1的全部或者部 分上下文信息, 如 LTE中的 E-RAB的配置信息包括 E-RAB的传输层地址、 QoS信息等; 终端的能力信息; 终端在基站 1或者核心网的信令连接信息, 以及其他的一些辅助信息, 用于协助基站 2进行相关的配置, 如终端希望的 连接点的目标小区, 终端的 RRM信息, 测量信息, 当前的测量配置等。
与传统 LTE切换源小区要将所有的上下文转移到目标小区, 由于基站 1 和基站 2同时和终端存在连接, 所以在新基站添加时不需要携带终端所有的 上下文, 也不需要配置失败后重建相关的信息, 基站 1仅需将和基站 2相关 的业务信息和配置信息发送给基站 2即可。
步骤 302: 基站 2在接收到基站 1发送的基站添加请求后, 首先进行接 纳控制, 检查是否有足够的资源可以接纳该多连接终端的业务, 如果可以则 进入后续流程, 否则基站 2发送基站添加请求响应给基站 1 , 通知基站 1添 加基站失败。
基站 2在准备响应的资源时, 根据其携带的业务 QoS要求, 配置相应的 专用无线资源, 专用无线资源配置信息包括空口协议栈的设置、 物理层的专 用资源(如在 LTE中会配置可能的专用 PUCCH资源和 Sounding资源 ) ,还 有可能包括专用的随机接入资源。 还有公用无线配置, 公共无线配置信息包 括如公共信道或者共享信道的配置信息。
还可能包括一些测量相关的配置信息, 或者测量相关的辅助配置信息, 这些测量信息可以是基于步骤 301中携带的辅助信息如原有的测量信息的基 础上修改而成的, 比如新的测量 ID可以使用原测量配置中没有使用的 ID, 其他如测量对象上报配置, 可以根据原测量配置中是否已有来决定是否新加 或者直接引用原有配置或者对原有配置进行修改, 从而避免测量的重复配置 和对应 ID的重复使用。 如果步骤 301 中没有携带测量配置信息, 则基站 2 可以根据自身需求设置相关的测量配置,发回给基站 1 , 由基站 1根据基站 2 的配置, 去除重复, 来调整最终发给终端的测量配置信息。
此外基站 2还需要配置终端业务对应的地面承载, 如 LTE中的 E-RAB 的隧道配置, 以及可能对应的业务的上下行数据前传隧道配置, 用以在业务 从基站 1转移至基站 2过程中, 空口未完成的上下行数据将前传至基站 2继 续传输。
基站 2完成上述配置后, 将终端的无线配置信息和基站 1需要的地面配 置信息通过基站添加请求响应携带的信息给基站 1 , 在所述基站添加请求响 应携带的信息中包括以下任一或任意多种:
无线配置信息、测量相关配置信息、所述其他基站的地面承载配置信息。 步骤 303:基站 1收到响应消息后,根据基站 2的无线配置则结合基站 1 的无线配置重配置情况以及当前终端的无线配置等因素, 由基站 1生成无线 重配置消息 (如 LTE的 RRC重配置消息) 。 可选的, 经过完整性保护加密 后, 通过空口直接发送给终端。 如果基站 2已经将无线配置组装成完整的无 线重配置消息, 则可选的经过的完整性保护加密后, 可以直接通过空口发送 给终端。 在所述无线重配置指令中携带有所述终端需要转移至所述至少一个 其他基站的业务、 所述至少一个其他基站的标识和新增小区的连接信息, 指 示所述终端与所述至少一个其他基站下的新增小区建立连接并在建立连接后 通过所述至少一个其他基站传输所述业务的数据。
步骤 304: 基站 1根据步骤 303收到的基站 2发送过来的无线配置, 建 立对应的 E-RAB地面承载和可选的建立数据前传承载。如果有未发送的数据 需要前传给基站 2,基站 1将通过前传隧道发送给基站 2,并且通过信令通道 将未完成的数据序列号状态通知给基站 2, 这点和 LTE的切换过程中切换是 类似的。
步骤 305: 终端按照所述无线重配置消息的指示, 随机接入指示的小区。 具体的, 终端接收到步骤 303中基站 1发来的无线重配置消息后, 按照信令 指示, 对对应的业务和无线承载进行配置。 当终端通过新的无线重配置消息 或者无线重配置中关于新基站配置的(如添加基站配置信元 )或多连接标识, 可以知道这是一个多连接的重配置, 终端需要和新基站下的小区进行连接。 终端按照配置中指示新增小区的连接信息和新增小区进行连接, 如和新增小 区同步后, 进行随机接入。
步骤 306: 终端在接入成功后, 通过无线信令承载发送无线重配置完成 消息给所述源基站。 终端和新增基站下的指定小区随机接入成功后, 通过无 线信令承载发送无线重配置完成消息给基站 1。 基站 1收到消息后, 确认终 端已完成重配置。 基站 1可以更新最终的配置。 如果终端在步骤 305失败, 则可以发送重配置失败给基站 1 , 基站 1发起后续的恢复流程, 删除基站 2 上的新增的无线资源和新增的地面配置, 然后保持原有的地面配置。
步骤 307: 基站 2在步骤 305中确认终端已经成功接入后 (如随机接入 成功), 发送路径变更请求给多流网关, 其中携带需要变更路径的业务的 ID 号或者对应的地面承载资源 ID, 例如在 LTE地面承载协议栈结构中, 携带 步骤 303中由基站 2发送过来的下行 GTP-U TEID信息和响应的 IP地址信息。
步骤 308: 多流网关新建和基站 2的地面数据承载,如保存根据步骤 307 中的基站 2地面承载信息, 并发送对应的上行地面承载信息, 通过路径变更 请求响应消息发送给基站 2, 并将制定的业务数据流从发送至原来的基站 1 到发送至基站 2。 基站 2收响应后, 接收的上行数据流发送给多流网关。
本发明的实施例二:
本发明实施例提供了一种终端多连接的管理方法。 本发明实施例中, 以 管理设备为独立的多流网关、 源基站为基站 1、 其他基站为基站 2为例, 基 站 1控制所述终端与基站 2建立连接, 多流网关在所述终端建立起与基站 2 的连接后, 将所述终端传输数据的路径更新为通过基站 1和基站 2。
与本发明的实施例一类似, 基于多流的触发条件, 如测量报告, 触发新 增基站 2进行多流传输。

步骤 401 :基站 1发送基站添加请求给基站 2。基站添加请求中会携带必 要的信息用于在基站 2侧准备多连接传输。 所述源侧信息包含以下信息的任 一或任意多种:
所述终端在所述源基站的全部或者部分上下文信息、 所述终端的能力信 息、 所述终端在所述源基站或者核心网的信令连接信息和辅助信息。
