Description

宏分集合并实现方法、 系统、 基站和用户设备
技术领域 本发明涉及网络通讯技术领域, 具体涉及一种宏分集合并实现方法、 系 统、 基站和用户设备。 背景技术
UMTS ( Universal Mobile Telecommunications System,通用移动通信系统 ) 是釆用 WCDMA ( Wideband Code Division Multiple Access, 宽带码分多址接 入) 空中接口技术的 3G ( 3rd Generation, 第三代移动通信) 系统, 通常也把 UMTS系统称为 WCDMA通信系统。 在 UMTS系统中,相邻小区的覆盖区域 会存在重叠, 利用软切换可以提供无缝切换, 通过宏分集合并 MDC ( Macro Diversity Combining ) 所实现的增益 , 可以增加系统的抗干 4尤能力。 随着移动通信技术的发展, 3G技术也在不断的发展演进。 在 3GPP ( 3rd Generation Partnership Project,第三代移动通信合作伙伴计划 )第 6版 ( Release 6,简称 "R6" )的版本中,引入了高速上行分组接入( High Speed Uplink Packet Access, 简称 "HSUPA" ) 。 HSUPA同样支持上行宏分集技术。 以下对 MDC的实现过程进行简单描述:软切换过程中的移动台与多个基 站同时通过两条不同的空中接口信道进行通信, 对于上行链路, 多个基站都 接收移动台的码分信道中的上行用户数据。 两个基站接收到的上行用户数据 均发送到 RNC ( Radio Network Controller, 无线网络控制器)进行选择合并, RNC利用提供给外环功率控制的帧可靠性指示符来选择其中一个较好的上行 用户数据, 并将选择的数据发送给核心网。
以上的网络架构是基于 3GPP R6以前版本的架构,为了提高 WCDMA的 生命周期和运营商的投资保护, 3GPP提出了 E-HSPA ( Evolved High Speed Packet Access, 演进的高速分组接入) 演进的研究计划, 希望在现有 R6版本 的基础上提高频谱效率, 减少控制面和用户面延迟, 并且能够后向兼容和前 向平滑演进到 LTE/SAE ( Long Term Evolution 3 GPP/System Architecture Evolution, 长期演进计划 /系统架构演进) 系统, 包括空口性能的提升和 RAN ( Radio Access Network, 无线接入网络) 架构的演进。 在 E-HSPA网络中, RNC功能下移到 NodeB+ ( E-HSPA NodeB , E-HSPA 基站) 。 NodeB+通过 IuPS接口直接与核心网相连。 在 E-HSPA网络中 MDC的一种实现过程为: 上行 MDC在用户的服务小 区基站中实现, 对于激活集中的所有无线链路上的数据, 如果某非服务小区 基站对应的无线链路上的接收数据正确, 则该基站将上行数据发送给该服务 小区基站, 服务小区基站对所接收到的上行数据, 进行宏分集合并处理之后 发送给核心网。 此方案类似于现有 3G系统 RNC中 MDC的实现, 只是将功 能实现的位置从 RNC 下移到服务小区基站上。 如果在服务小区基站 (包括 SRNC ( Serving RNC, 服务 RNC )功能)上实现上行宏分集, 则必然需要基 站之间相互通讯。 如果让其他软切换基站都传输上行接收数据给该服务小区 基站进行宏分集处理, 会有基站之间接口传输(最后一公里传输资源) 负载 过大和用户面的时延问题。
可见, 不论是引入了 HSUPA的系统或者 E-HSPA, 釆用的上述方案是以 实现 MDC为前提的, 该方案存在不够灵活的缺点: 比如, 如果运营商希望通 过一定的性能下降 (比如不釆用 MDC )来换取传输资源的节约, 该要求在这 个方案的基础上就没有办法得到满足。
当然, 上述系统也可以不釆用 MDC, 从而节省基站之间的传输资源。 但 是, 如果不实现宏分集, 性能会有一定的下降。 可见, 这种方案是以不实现 MDC增益的前提下完成的, 一定程度上降低了系统性能。
综上所述, 在实现本发明的过程中, 发明人发现上述现有技术至少存在 ^下问题: 现有技术的解决方案中, 或者是釆用 MDC, 或者不釆用 MDC, 而没有考 虑到针对不同特性的业务, 釆用 MDC所获得增益是不同的。 所以, 还没有一 种解决方案, 可以根据业务特性以更加灵活方式实现宏分集合并, 从而提高 系统的性能。 发明内容 本发明实施方式提供一种宏分集合并实现方法、 系统、 基站和用户设备, 可以根据 UE当前业务的业务特性, 以更加灵活的方式实现宏分集合并, 优化 系统性能。 本发明实施方式提供的一种宏分集合并实现方法, 应用于包括非服务小 区基站和用户设备 UE的通信系统, 所述方法包括: 非服务小区基站根据 UE当 前业务的业务特性, 判断所述 UE当前业务中是否存在业务特性满足预定条件 的业务; 若判断结果为是, 则非服务小区基站将业务特性满足预定条件的业 务作为需要宏分集合并 MDC的业务进行处理。 本发明另一个实施方式提供的一种基站, 用于实现宏分集合并, 包括: 判断单元, 用于根据 UE当前业务的业务特性, 判断所述 UE当前业务中是否存 在业务特性满足预定条件的业务; 处理单元, 用于当所述判断单元的判断结 果为是时, 将业务特性满足预定条件的业务作为需要 MDC的业务进行处理。 本发明另一个实施方式提供的一种网络节点, 用于执行 MDC操作, 包括: 接收单元, 用于接收非服务小区基站发送的根据业务特性判断需要 MDC的业 务; MDC执行单元, 用于对所述接收单元接收到的业务执行 MDC操作。 本发明再一个实施方式提供的一种用户设备 UE, 用于软切换中的宏分集 合并实现过程, 包括: 指示接收单元, 用于接收网络节点的指示, 所示指示 表示若 UE当前业务中同时存在需要 MDC的业务和不需要 MDC的业务时,所述 需要 MDC的业务和不需要 MDC的业务需要分别包含在不同的传输块中; 处理 单元, 用于根据指示接收单元接收到的指示, 将所述需要 MDC的业务和不需 要 MDC的业务分别包含在不同的传输块中; 发送单元, 用于将所述处理单元 处理的传输块发送给非服务小区基站。 本发明再一个实施方式提供的一种实现宏分集合并的系统, 包括用户设 备 UE、 非服务小区基站和执行 MDC的网络节点, 所述非服务小区基站包括: 判断单元, 用于根据 UE当前业务的业务特性, 判断所述 UE当前业务中是否存 在业务特性满足预定条件的业务; 处理单元, 用于当所述判断单元的判断结 果为是时, 将业务特性满足预定条件的业务作为需要 MDC的业务进行处理; 所述执行 MDC的网络节点包括: 接收单元, 用于接收非服务小区发送的根据 业务特性判断需要 MDC的业务; MDC执行单元, 用于对所述接收单元接收到 的业务执行 MDC操作。 通过上述技术方案的描述可知, 本发明实施方式提供的技术方案, 由非 服务小区基站判断 UE业务是否满足预定条件,将满足预定条件的业务作为需 要 MDC的业务进行处理。 这样, 可以根据业务特性以更加灵活方式实现宏分 集合并, 从而提高系统的性能。 附图说明 图 1是本发明第一个实施例提供的 E-HSPA系统中 MDC实现方法示意图; 图 2是本发明第二个实施例提供的 E-HSPA系统中 MDC实现方法示意图; 图 3是本发明第三个实施例提供的 E-HSPA系统中 MDC实现方法示意图; 图 4是本发明第四个实施例提供的实现 MDC的系统结构示意图。 具体实施方式 下面对本发明实施方式的宏分集合并实现方法进行说明, 可以理解的是, 本发明实施方式只是举例。 另夕卜, 本发明实施方式以 WCDMA和 E-HSPA系统 为例进行说明, 但可以理解的是, 本发明实施方式提供的技术方案同样适用 于 LTE/SAE等系统中。
在方法实施方式中, 由非服务小区基站根据 UE当前业务的业务特性, 判 断 UE当前业务中是否存在业务特性满足预定条件的业务, 如果有, 则将该业 务特性满足预定条件的业务作为需要 MDC的业务。 然后相应的, 进行后续的 流程。
该预定的条件可以由系统来设定, 系统设定好之后, 或者在各个网络节 点 ( WCDMA中的服务小区基站、 RNC, E-HSPA系统中的服务小区基站、 非 服务小区基站等) 中预先配置该预定条件, 或者在某个或某几个网络节点中 预先配置该预订条件, 再由配置好预订条件的网络节点通过消息告知其他网 络节点。
而如前所述, 具体条件可以有多种:
1、 从业务速率的角度来考虑, 当 UE业务的业务速率低于第一门限, 则认 为满足了预定条件。 该第一门限可以按照系统策略设定, 比如, 限定第一门 限为 100kbps。
2、 从业务优先级的角度来考虑, 当 UE业务的业务优先级大于第二门限, 则认为满足了预定条件。 该第二门限可以按照系统策略设定, 比如, 限定优 先级大于 10的业务为需要 MDC的业务。
3、 以业务类型作为条件, 比如, 可以将 CS话音, VoIP话音, 接近实时业 务的游戏业务或者低速的交互业务、 背景业务等, 作为需要 MDC的业务。
4、 综合业务速率和业务优先级, 当 UE业务的业务速率低于第三门限, 且 所述 UE业务的业务优先级大于第四门限时, 认为满足了预定条件。 这里的第 三门限可以和上述第一门限相同或不同, 第四门限可以和第二门限相同或不 同。 5、 当然, 判断条件还可以是上面几个因素的其他组合, 比如 "业务速率 +业务类型" 、 "业务优先级 +业务类型" 、 "业务速率 +业务优先级 +业 务类型" 等, 本发明实施例对该预设条件不做限定, 此处不再一一列举。 确定出存在需要 MDC的业务之后, 非服务小区基站将进行相应的处理, 下面分别进行简单描述: 如果 UE当前业务中存在需要 MDC的业务, 那么, 非服务小区基站建立与 需要执行 MDC操作的网络节点的用户面传输承载, 并且将该需要 MDC业务对 应的上行用户数据通过该用户面传输承载发送至该执行 MDC操作的网络节 点。 在 WCDMA系统中, 该网络节点是 RNC, 在 E-HSPA系统中, 该网络节点 是服务小区基站(具有 SRNC功能) , LTE系统中, 该网络节点是服务小区基 站 ( E-NODEB ) 。 如果 UE当前业务中不存在需要 MDC的业务, 那么, 非服务小区基站并不 建立与上述网络节点的用户面传输承载, 即不转发上行用户数据。 而且, 非 服务小区基站可以只解调空口的上行控制信道, 对 UE上行功率进行控制, 以 实现干扰控制。 以下分别举具体实施例, 对本发明技术方案进行详细描述。
实施例一, 以 E-HSPA系统中, UE当前业务只有为低速、 实时业务的 VOIP 为例, 对本发明实施例提供的宏分集合并实现方法进行说明。 图 1为本实施例 的宏分集合并实现方法示意图。 在软切换状态下, 服务小区基站首先要触发非服务小区建立承载用户业 务的无线链路。 例如, 服务小区根据 UE的测量报告, 判断出需要在激活集中增加该非服 务小区时, 触发非服务小区建立承载用户业务的无线链路。 非服务小区基站 在该无线链路上接收 UE发送的业务后, 进行步骤 101的判断。 步骤 101 : 非服务小区基站根据 UE当前业务的业务特性, 判断 UE当前业 务中是否存在业务特性满足预定条件的业务, 若存在则执行步骤 102, 若不存 在则执行步骤 103; 假设本实施例的预定条件是 "业务速率 +业务优先级" , 具体的, 该条 件为 "业务速率小于 100kbps、 且业务优先级高于 10" 。 本实施例中, 以 UE 当前业务只有 VOIP为例, 而 VOIP是满足上述条件的。 所以, 非服务小区基站 判断 VOIP的业务特性满足预定条件, 即 UE当前业务中存在业务特性满足预定 条件的业务, 执行步骤 102。 步骤 102、非服务小区基站将满足预定条件的业务作为需要 MDC的业务进 行处理; 本步骤包括以下子步骤:
1021、 确定 UE当前业务中存在业务特性满足预定条件的业务后, 建立与 服务小区基站之间的用户面传输承载;
1022、 非服务小区基站解调上行控制信道和上行数据信道; 本步骤中, 非服务小区基站通过解调上行控制信道和数据信道, 对 UE发 送的上行业务数据进行处理, 该业务数据是需要 MDC的业务数据。
1023、 非服务小区基站将解调出的需要 MDC的业务的上行业务数据封装 成数据帧;
1024、 非服务小区基站将封装后的数据帧发送给执行 MDC的网络节点, 即服务小区基站。 本步骤中, 在步骤 1021建立的用户面传输承载上, 非服务小区基站向服 务小区基站发送该数据帧。该数据帧可以是 FP数据帧,即包括 FP包头的 MAC-d 流。 当然, 可以理解的是, 非服务小区基站只向服务小区基站发送接收正确 的数据。 所以, 步骤 102中, 隐含了数据校验的细节, 由于该细节是本领域所 共知, 本实施例不予详细描述。 可以理解的是, 服务小区基站收到该数据帧后, 对其进行 MDC操作的步 骤为现有技术, 此处不再赘述。
步骤 103、 非服务小区基站只接收和解调上行控制信道, 实现对 UE的上行 功率控制。 由于本实施例中以只存在 VOIP为例进行说明, 所以不需要执行步骤 103。 但需要说明的是,在步骤 102中,也存在通过控制信道对 UE进行功率控制的步 骤, 不同之处在于, 步骤 103中, 非服务小区基站并不建立与服务小区基站的 用户面传输承载, 即不转发上行用户数据, 也就不需要对上行数据信道进行 解调。
实施例二, 以 E-HSPA系统中, UE当前业务只有高速文件上传业务为例, 对本发明实施例提供的宏分集合并实现方法进行说明。 图 2为本实施例的宏分 集合并实现方法示意图。
步骤 201 : 非服务小区基站根据 UE当前业务的业务特性, 判断 UE当前业 务中是否存在业务特性满足预定条件的业务, 若存在则执行步骤 202, 若不存 在则执行步骤 203; 假设本实施例的预定条件是 "业务速率 +业务优先级" , 具体的, 该条 件为 "业务速率大于 100kbps、 且业务优先级高于 10" 。 由于本实施例中, UE 当前业务只有高速文件上传业务为例, 所以, 非服务小区基站判断高速文件 上传业务的业务特性不满足预定条件, 即 UE当前业务中不存在业务特性满足 预定条件的业务, 执行步骤 203。 步骤 202、非服务小区基站将满足预定条件的业务作为需要 MDC的业务进 行处理; 由于本实施例中以只存在高速文件上传业务为例进行说明, 所以不需要 执行步骤 202。 步骤 203、 非服务小区基站只接收和解调上行控制信道, 实现对 UE的上行 功率控制。 本步骤中, 由于该业务属于不需要 MDC的业务, 即当前业务中没有满足 预定条件的业务, 那么, 非服务小区基站并不建立与服务小区基站的用户面 传输承载, 即不转发上行用户数据。 而且, 非服务小区基站可以只接收和解 调空口的上行控制信道, 对 UE上行功率进行控制, 以实现干扰控制。
具体的, 可以釆用如下方式: 在建立非服务的无线链路时, 在该无线链 路中仅设置用于估计该 UE对小区上行负载贡献的上行控制信道和用于控制该 UE发射功率的下行控制信道; 非服务小区基站根据从该上行控制信道收到的 信号, 估计 UE对小区上行负载的贡献, 并根据该估计的结果通过该下行控制 信道控制 UE的上行发射功率。 釆用这样的干扰控制方式, 节省了非服务小区 的上行数据信道解调资源。
实施例三, 仍以 E-HSPA系统为例, 且 UE当前业务既包括为低速、 实时业 务的 VOIP、 又包括高速文件上传业务为例, 对本发明实施例提供的宏分集合 并实现方法进行说明。 如图 3所示:
步骤 301 : 非服务小区基站根据 UE当前业务的业务特性, 判断 UE当前业 务中是否存在业务特性满足预定条件的业务, 若存在则执行步骤 302, 若不存 在则执行步骤 303;
仍假设本实施例的预定条件是 "业务速率 +业务优先级" , 具体的, 该 条件为 "业务速率大于 100kbps、 且业务优先级高于 10" 。 由于 UE当前有两种 不同业务特性的业务, 并且根据系统预设的规则, VOIP属于业务特性满足预 定条件的业务, 即需要 MDC的业务, 而高速文件上传业务属于业务特性不满 足预定条件的业务, 即不需要 MDC的业务, 那么, 非服务小区判断的结论是: UE当前业务中存在业务特性满足预定条件的业务, 接着需要执行步骤 302。 需要说明的是, 由于 UE当前有两种不同业务特性、 且是需要做不同处理 的业务, UE向非服务小区基站发送业务时, 可以釆用两种方式: 方式一、 满 足预定条件的业务和不满足预定条件的业务, 包含在不同的传输块中, 发送 给非服务小区基站, 即,将 VOIP和高速上传业务并不复用在同一个传输块中。 方式二、 满足预定条件和不满足预定条件的业务数据, 包含在同一个传输块 中, 即, 将 VOIP和高速上传业务复用在同一个传输块中。 而如果 UE以第一方式来发送业务, 可以由服务小区基站设置需要 MDC的 业务和不需要 MDC的业务不能复用在同一个传输块, 由服务小区基站告知 UE。 或者是由系统预先设置该规则。 步骤 302、非服务小区基站将满足预定条件的 VOIP业务作为需要 MDC的业 务进行处理;
本步骤包括以下子步骤:
3021、 确定存在需要 MDC的 VOIP后, 即 UE当前业务中存在需要 MDC的 业务, 建立与服务小区基站之间的用户面传输承载;
3022、 非服务小区基站解调上行控制信道和上行数据信道;
本步骤中, 非服务小区基站通过解调上行控制信道和上行数据信道, 对 UE发送的业务数据进行处理, 该业务数据是需要 MDC的 VOIP业务数据。
3023、 非服务小区基站将解调出的需要 MDC的业务的上行业务数据封装 成数据帧;
由于步骤 301中 UE向非服务小区基站发送业务可能有不同的发送方式,在 3023中有相应的处理方式: 若在步骤 301中, 釆用的是方式一, 即需要 MDC和不需要 MDC的业务数 据没有复用在同一个传输块中。 则非服务小区基站将包含业务特性满足预定 条件的业务的传输块封装成第一数据帧, 在步骤 3021建立的传输承载上向服 务小区基站发送该第一数据帧。 如果是釆用这样的方式, 则非服务小区可以基于现有的实现方式, 不需 要做进一步改动。 若在步骤 301中, 釆用的是方式二, 即需要 MDC和不需要 MDC的业务数 据复用在同一个传输块中。 则非服务小区基站对该传输块解复用, 将业务特 性满足预定条件的业务封装成第一数据帧, 在步骤 3021建立的传输承载上向 服务小区基站发送该第一数据帧。
3024、 非服务小区基站将封装后的 VOIP业务的数据帧发送给服务小区基 站;
非服务小区基站在步骤 3021建立的用户面传输承载上, 向服务小区基站 发送该数据帧。
可以理解的是, 服务小区基站收到该封装了的数据帧后, 对其进行 MDC 操作的步骤为现有技术, 此处不再赘述。 步骤 303、 非服务小区基站只接收和解调上行控制信道, 实现对 UE的上行 功率控制。 由于本实施例中以存在需要 MDC的业务进行说明, 所以不需要执行步骤 303。 但需要说明的是, 在步骤 302中, 也存在通过控制信道对 UE进行功率控 制的步骤, 不同之处在于, 步骤 303中, 非服务小区基站并不建立与服务小区 基站的用户面传输承载, 即不转发上行用户数据, 也就不需要对上行数据信 道进行解调。
WCDMA系统中, 与上述实施例中 E-HSPA系统的技术方案不同之处在 于: 1、 执行 MDC的网络节点不同, WCDMA系统中, 该网络节点为 RNC; 2、涉及到 UE当前同时具有需要 MDC和不需要 MDC的不同业务时,预先设 置 UE发送方式的网络节点不同, WCDMA系统中,该网络节点可以为 RNC。 由于基本流程大体类似,不再对 WCDMA系统的类似技术方案进行详细描述。 实施例四, 为本发明实施例提供的实现宏分集合并的系统实施例, 且以 E-HSPA系统为例。 图 3为本实施例的系统结构示意图。 该系统包括: 用户设备 UE、 非服务小区基站和执行 MDC的网络节点, 在该系统中, 该网络节点为服务小区基站。 非服务小区基站包括:判断单元 401 ,用于根据 UE当前业务的业务特性, 判断所述 UE 当前业务中是否存在业务特性满足预定条件的业务; 处理单元 402 , 用于当所述判断单元的判断结果为是时, 将业务特性满足预定条件的业 务作为需要 MDC的业务进行处理。 服务小区基站包括: 接收单元 403 , 用于接收非服务小区发送的根据业务 特性判断需要 MDC的业务; MDC执行单元 404 , 用于对所述接收单元接收 到的业务执行 MDC操作。 下面对非服务小区基站和服务小区基站进行详细描述。 非服务小区基站, 包括: 判断单元, 用于根据 UE当前业务的业务特性, 判断所述 UE当前业务中是否存在业务特性满足预定条件的业务; 处理单元, 用于当所述判断单元的判断结果为是时, 将业务特性满足预定条件的业务作 为需要 MDC的业务进行处理。 进一步的, 该处理单元可以由以下子单元实现其功能: 承载建立子单元, 用于当所述判断单元的判断结果为是时,建立与执行 MDC的网络节点之间的 用户面承载; 发送子单元, 用于在所述承载建立子单元所建立的承载上, 将 所述业务特性满足预定条件的业务发送给所述执行 MDC的网络节点。在该系 统中, 执行 MDC的网络节点是服务小区基站。 更进一步的, 该发送子单元可以由以下子单元实现其功能: 解调子单元, 用于解调上行控制信道和上行数据信道; 封装子单元, 用于将解调出的需要 MDC的业务的上行业务数据封装成数据帧; 执行子单元, 用于将封装后的数 据帧发送给所述执行 MDC的网络节点。 当判断单元的判断结果为否时, 该非服务小区基站可以包括: 功控单元, 用于当所述判断单元的判断结果为否时, 只接收和解调上行控制信道, 实现 对 UE的上行功率控制。 进一步的,该判断单元可以包括:接收子单元,用于接收 UE发送的业务; 若所述业务中同时包括业务特性满足预定条件的业务和业务特性不满足预定 条件的业务, 则所述接收子单元接收到的业务中, 所述特性满足预定条件的 业务和业务特性不满足预定条件的业务分别包含在不同的传输块中。 实施例五, 为本发明实施例提供的用户设备的实施例。 该用户设备 UE, 用于软切换中的宏分集合并实现过程, 包括: 指示接收单元,用于接收网络节点的指示, 所示指示表示若 UE当前业务 中同时存在需要 MDC的业务和不需要 MDC的业务时, 所述需要 MDC的业 务和不需要 MDC的业务需要分别包含在不同的传输块中; 处理单元, 用于根据指示接收单元接收到的指示,将所述需要 MDC的业 务和不需要 MDC的业务分别包含在不同的传输块中;
由于本发明实施例子提供的方案中, 由非服务小区基站根据业务特性, 判断 UE业务是否满足预定条件,从而决定是否将该业务作为需要 MDC的业 务, 可以根据业务特性以更加灵活方式实现宏分集合并。 对于需要实现上行 宏分集的业务, 非服务小区基站将数据转发给服务小区基站; 对于不需要实 现上行宏分集的业务, 非服务小区基站不需要转发数据给服务小区基站, 同 时可以只解调空口的上行数据信道, 对 UE进行上行功率控制。 比如, 当预设 条件为低速、 实时业务需要 MDC时, 可以实现: 对于低速、 实时的业务利用 上行宏分集合并增益提高性能; 对于高速、 非实时的业务(比如 web浏览, 高速数据上传)取消上行宏分集合并, 减少传输资源浪费。 总之, 釆用基于 业务特性进行有选择性的上行宏分集方案后, 解决了传输资源浪费问题的同 时, 兼顾了针对不同业务的系统性能的优化。 再者, 网络节点可以预先配置需要 MDC的业务特性,根据预先设置的条 件进行相应的处理。 另外, 如果预先设置需要 MDC的业务数据和不需要 MDC的业务数据不 复用在同一个传输块中, 则非服务小区可以基于现有的实现方式, 不需要做 进一步改动。 当然, 相应的, 可以在服务小区基站中设置该规则, 告知 UE, 也可以是系统设置该规则。 可以理解的是, 当 UE当前业务有多种时, 其向非 服务小区基站发送时, 可以釆用不同的方式。 本发明实施例提供了多种技术 实现的可能,根据 UE当前业务的业务特性, 以更加灵活的方式实现宏分集合 并, 优化系统性能。 可以理解的是, 本发明实施例提供的技术方案, 不仅适用于 WCDMA、 E-HSPA, 而且, 对 LTE/SAE等系统都适用。 其他系统中, 执行 MDC的网络 节点有所不同。 虽然通过实施例描绘了本发明, 本领域普通技术人员知道, 本发明有许 多变形和变化而不脱离本发明的实质, 本发明的申请文件的权利要求包括这 些变形和变化。
