Description

调度方法、 基站和基站控制器 技术领域
本发明实施例涉及通信技术领域， 并且更具体地， 涉及调度方法、 基站 和基站控制器。 背景技术
为了满足用户多样性业务的需求，在异构网络中，存在多种节点的部署， 如高功率的宏基站和多种类型的低功率节点。 低功率节点包括微基站、 微微 基站、 毫微微基站、 中继站等。
异构网络的同频组网场景下， 例如， 宏基站和敫基站使用相同的频点， 在不增加频点资源的情况下， 通过微基站的热点覆盖或补盲， 提高系统的总 的吞吐量，用户的服务质量。但是， 同频组网的网络会产生同频干扰的问题， 尤其是对在服务小区覆盖边缘的用户会产生很大的性能负增益。
例如， 在宏基站和微基站的软切换区域， 为了获得较高的吞吐量， 服务 小区为微基站的 UE (下文中也可以称为 "微网 UE" )会满功率地传输上行 数据， 但是， 该上行传输信号对于服务小区为宏基站的 UE (下文中也可以 称为 "宏网 UE" ) 而言为干扰信号， 从而降低了宏网 UE的性能。 又例如， 微基站向微网 UE传输下行数据， 虽然微基站的功率比宏基站的功率小， 但 是在微基站覆盖附近区域的宏网 UE仍能接收到该微基站的下行信号。因此， 该下行传输信号为影响宏网 UE性能的干扰信号。 再例如， 宏基站向在微基 站覆盖附近区域的宏网 UE传输下行数据时， 对于微网 UE也会产生干扰， 从而影响 网 UE的性能。 发明内容

本发明的技术方案， 可以应用于各种通信系统， 例如： 全球微波互联接 入 ( WiMAX, Worldwide Interoperability for Microwave Access )、 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 ) , UMTS ( Universal Mobile Telecommunications System,通用移动通信系统；)，通用分组无线业务（ GPRS, General Packet Radio Service ), 长期演进 ( LTE, Long Term Evolution )等。
用户设备 （ UE , User Equipment ) , 也可称之为移动终端 （ Mobile Terminal ),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， 用户设备可以是移动终端， 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。
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 ), 本发明并不限定， 但为描述方便， 下述实 施例以 NodeB为例进行说明。
基站控制器，可以是 GSM或 CDMA中的基站控制器（ BSC, Base Station Controller ), 也可以是 WCDMA中的无线网络控制器（ RNC , Radio Network Controller ), 还可以合并在 LTE的演进型基站（ eNB或 e-NodeB , evolutional Node B ) 中， 本发明并不限定， 但为描述方便， 下述实施例以 RNC为例进 行说明。
为了描述方便， 下述实施例以 WCDMA 系统为例进行说明。 应理解， 本发明实施例并不限于此， 可以为 WCDMA系统之外的其它移动通信系统。
图 1是可实施本发明实施例的网络系统的示意场景图。 在图 1中， 宏基 站 101和微基站 102同频， 即工作在相同的中心频点上。 UE 103的服务小 区是宏基站， UE 104的服务小区是微基站。 UE 103和 UE104是处于软切换 区域的特定 UE。 特定 UE指的是性能较低的 UE, 表示 UE性能的参数可以 包括下列之一或任意组合： 吞吐量、 信号强度、 信号质量等。 性能较低可以 通过表示 UE性能的参数与阈值相比较来进行判断， 如吞吐量小于或等于吞 吐量阈值、 信号强度小于或等于强度阈值、 或者信号质量小于或等于质量阈 值等。 应理解， 本发明实施例对此并不限定。
应注意， 图 1的网络系统仅仅是为了更清楚地描述本发明实施例而给出 的可实施本发明的一种场景， 而非要限制本发明实施例的应用范围。 例如， 图 1中描绘了一个宏基站 101、 一个微基站 102以及两个 UE 103和 104, 但是本发明实施例还可以包含更多数目的基站， 或者还可以包含更多数目的 UE。 基站除了上述宏基站和微基站， 还可以是其它类型的基站， 如微微基 站、 毫 i i基站、 中继站等。 本发明实施例对此并不限定。 另外， 在图 1的 网络系统中， 本发明实施例对于 UE所处的地理位置并不限定。
图 2是本发明一个实施例的调度方法的流程图。 图 2的方法由基站控制 器执行。
201 , 确定启用特定用户设备 UE的优先调度。
202, 向基站发送指示信息， 该指示信息用于指示基站对特定 UE执行 优先调度。
其中，特定 UE指的是性能较低的 UE,表示 UE性能的参数可以包括下 列之一或任意组合： 吞吐量、 信号强度和信号质量等。 性能较低可以通过表 示 UE性能的参数与阈值相比较来进行判断， 如吞吐量小于或等于吞吐量阈 值、 信号强度小于或等于强度阈值、 或者信号质量小于或等于质量阈值等。
本发明实施例中基站控制器在确定启用特定用户设备 UE优先调度的情 况下向基站发送指示信息， 基站根据该指示信息对特定 UE执行优先调度， 从而提高了特定 UE的性能。
可选地， 作为一个实施例， 在步骤 201中， 基站控制器可以根据处于软 切换区域的 UE个数确定启用或者不启动特定 UE优先调度。 例如， 如果处 于宏小区和微小区软切换区域且服务小区为宏小区的 UE 个数大于某个阈 值， 则基站控制器可以确定启用 HSUPA ( High Speed Uplink Packet Access , 高速上行链路分组接入）特定 UE优先调度。 应理解， 本发明实施例对于 UE 的服务小区为微小区还是宏小区并不限定。 例如， 基站控制器还可以确 定启用 HSDPA ( High Speed Downlink Packet Access, 高速下行链路分组接 入）特定 UE优先调度， 本发明实施例对此不作限定。
可选地， 作为另一个实施例， 在步骤 201中， 如果 UE在选择服务小区 时采用了扩展小区覆盖的方案， 则确定启用特定 UE的优先调度。 例如， 如 果 UE在选择服务小区时采用了偏置值， 则基站控制器可以确定启用特定 UE优先调度。 具体地， 某个 UE测量到宏小区的信号比微小区的信号强， 如果没有设置正偏置值， UE 的服务小区应为宏小区。 但是， 为了在不增加 微小区的发射功率的前提下提高微小区覆盖， UE在选择服务小区过程中， 在测量的微小区信号值上再加上一个信号正偏置值。 此时， UE计算得到微 小区的信号比宏小区的信号强， 因此， UE选择微小区作为服务小区。 因此, 如果 UE在选择服务小区时， 检测微小区信号采用了信号偏置值， 基站控制 器可以确定在该微小区中启用特定 UE的优先调度。 应理解， 本发明对此并 不限定， 即无论是在微小区采用了偏置值还是宏小区采用了偏置值， 以及何 种原因引入偏置值均落入本发明的范围内。 还应理解， UE在选择服务小区 时采用了其他扩展小区覆盖的方案， 也可以作为启用优先调度的依据。
可选地， 作为另一个实施例， 在步骤 202之前， 基站控制器可以确定优 先调度的目标 UE, 并且在步骤 202中向基站发送的指示信息还用于指示该 目标 UE的标识。 进一步地， 基站可以将目标 UE作为需要执行优先调度的 特定 UE,或者基站可以在目标 UE中选择部分目标 UE作为需要执行优先调 度的特定 UE。 在一种实现方式下， 基站控制器可以根据 UE的吞吐量、 UE 的信号强度和 /或 UE的信号质量确定优先调度的目标 UE。 在另一种实现方 式下， 基站控制器可以将处于宏小区和微小区软切换区域的 UE确定为优先 调度的目标 UE。 这样， 能够有效地提高网络调度的灵活性。
例如， UE的服务小区是宏小区， UE的吞吐量小于某个阈值， 基站控制 器可以将该 UE确定为目标 UE。 又例如， 将处于宏小区和微小区软切换区 域的 UE作为目标 UE, 进一步地， 可以是处于宏小区和微小区软切换区域 且服务小区是宏小区或者微小区的 UE作为目标 UE,或者 UE的信号质量低 于某个阈值时，基站控制器将该 UE确定为目标 UE。信号质量可以是 CPICH ( Common Pilot Channel, 公共导频信道） 信噪比 Ec/No , CPICH RSCP ( Received Signal Code Power, 接收信号码功率）或者路径损耗 ( Pathloss ) 值等。 应理解， 本发明实施例对此并不限定。
应理解， 本发明实施例对于基站控制器确定优先调度的目标 UE的方式 并不限定， 即无论基站控制器以何种形式确定优先调度的目标 UE均落入本 发明范围内。
可选地， 作为另一个实施例， 在步骤 202中， 在一种实现方式下， 基站 控制器可以向基站发送信令消息， 信令消息携带指示信息。 以 WCDMA为 例， 基站控制器可以通过 lub接口 （无线网络控制器 RNC与 NodeB之间的 逻辑接口）， 在 NBAP ( NodeB Applicant Part, 基站应用部分协议 )现有的消 息中增加一个 IE ( Information Element, 信息单元）指示基站启用特定 UE 的优先调度。 如， 可以在系统消息更新请求 （ System Information Update Request ) 消息中增加 IE, 用于指示 NodeB采用或者不采用特定 UE的优先 调度。 进一步地， 指示信息还可以用于指示目标 UE的标识。 例如， 基站控 制器可以通过 lub接口， 利用 NBAP现有的消息， 如无线链路建立请求消息 ( Radio Link Setup Request ), 指示基站控制器确定的需要优先调度的目标 UE。 该无线链路建立请求消息（ Radio Link Setup Request )本身就携带相关 UE的标识，在该消息中增加一个 IE指示 NodeB采用或者不采用特定 UE的 优先调度。 应理解， 本发明实施例并不限于此， 基站控制器还可以新增加一 条 NBAP消息作为指示消息来完成指示基站采用或者不采用特定 UE的优先 调度， 或者新增加一条 NBAP消息作为指示信息来指示目标 UE的标识。
在另一种实现方式下，基站控制器可以通过用户面的 FP( frame protocol ) 帧将指示信息发送给基站。 以 WCDMA 为例， 基站控制器可以通过在 lub 接口下行数据帧中增加一个标记（flag )指示基站启用或者不启用特定 UE 的优先调度。 如， 在 HS-DSCH ( High Speed Downlink Shared Channel, 高速 下行共享信道） 中的 HS-DSCH数据帧类型 1中增加一个 flag。 进一步地， 指示信息还可以用于指示目标 UE的标识。 例如， 基站控制器可以通过 lub 接口下行数据帧 （如 HS-DSCH数据帧类型 3 )指示基站控制器确定的需要 优先调度的目标 UE。 如果数据帧中含有某个 UE的标识， 则可以将该 UE 的标识作为目标 UE的标识。 应理解， 本发明实施例对使用的具体用户面数 据帧的类型并不限定。
应注意， 本发明实施例对于基站控制器发送指示信息的形式并不限定。 本发明实施例不仅可以采用上述显式的方式发送指示信息，也可以采用隐式 的方式发送指示信息。 例如， 基站控制器可以通过专用消息或专用帧向基站 发送目标 UE的标识， 基站则理解应对该目标 UE执行优先调度， 而无需发 送一个单独的指示信息。 例如， 基站控制器向基站发送一个优先调度消息， 基站只要收到这个消息就采用或者不采用特定 UE的优先调度。 如果这个消 息中携带了目标 UE的标识， 那么基站可以将这些目标 UE确定为特定 UE 或者根据目标 UE的参数值确定特定 UE。
可选地， 作为另一个实施例， 启用特定 UE优先调度可以是增加特定 UE的调度资源分配和 /或增加特定 UE的调度频率。 例如， 按照原有的调度 算法， 基站平均每秒对特定 UE的调度次数为 n, 采用优先调度算法后， 基 站平均每秒对特定 UE的调度次数为 m, m>n。 又例如， 按照原有的调度算 法， 特定 UE的调度资源为总调度资源的 10%, 采用优先调度算法后， 特定 UE的调度资源为总调度资源的 30%。 因此， 特定 UE分配到更多的调度资 源， 这样， 能够有效地改善特定 UE的性能， 提高特定 UE的吞吐量。
应理解， 上述特定 UE的调度资源占总调度资源的比例取值仅仅是示例 性的， 而非对本发明的限制。 还应理解， 本发明实施例对特定 UE采用何种 优先调度算法并不限定。
下面还将结合具体实施例， 更加详细地描述本发明实施例的调度方法的 非限制性的例子。
图 3是本发明另一个实施例的调度方法的流程图。 图 3的方法由基站执 行（如图 1所示的宏基站 101或 基站 102 ), 并与图 1的方法相对应， 因此 将适当省略与图 1的实施例重复的描述。
301 , 接收基站控制器发送的指示信息。
302, 根据指示信息对特定用户设备 UE执行优先调度。
其中，特定 UE指的是性能较低的 UE,表示 UE性能的参数可以包括下 列之一或任意组合： 吞吐量、 信号强度、 信号质量等。 性能较低可以通过表 示 UE性能的参数与阈值相比较来进行判断， 如吞吐量小于或等于吞吐量阈 值、 信号强度小于或等于强度阈值、 或者信号质量小于或等于质量阈值等。
本发明实施例中基站控制器在确定启用特定用户设备 UE优先调度的情 况下向基站发送指示信息， 特定 UE为性能较低的 UE, 基站根据该指示信 息对特定 UE执行优先调度， 从而提高了特定 UE的性能。
可选地， 作为一个实施例， 在步骤 301中， 基站可以接收基站控制器发 送的信令消息，信令消息携带指示信息。指示信息包括但不限于 NBAP消息。 基站还可以接收基站控制器发送的用户面数据帧，用户面数据帧携带指示信 息。 指示信息包括但不限于下行数据帧。 进一步地， 指示信息还可以用于指 示目标 UE的标识。 应理解， 本发明实施例对此并不限定。 对于指示信息的 发送方式如上所述， 此处不再赘述。 应注意， 本发明实施例对于基站控制器 发送指示信息的形式并不限定。
可选地， 作为另一个实施例， 在步骤 302中， 在一种实现方式下， 基站 控制器可以确定目标 UE, 并在指示信息中携带该目标 UE的标识， 将指示 信息发送给基站， 基站可以根据指示信息确定目标 UE, 在目标 UE中确定 特定 UE。 基站控制器确定目标 UE的方式如上所述， 此处不再赘述。 进一 步地， 基站可以根据目标 UE的参数值确定特定 UE。 在另一实现方式下， 基站可以根据 UE的参数值确定特定 UE。参数值包括但不限于： CQI( Channel Quality Indicator, 信道质量指示 )值、 SIR ( Signal to Interference Ratio, 信 号干扰比）、 SI ( Scheduling Information, 调度信息）等。 应理解， 本发明实 施例对此并不限定。 这样， 能够有效地提高网络调度的灵活性。
例如， UE在物理层上报的 CQI值和 /或 UE MAC( Media Access Control, 媒体接入控制）层上报的 SI低于相应的阈值，基站可以确定该 UE为需要进 行优先调度的特定 UE。 或者， 目标 UE的 CQI值低于某个阈值， 基站可以 确定该目标 UE为需要进行优先调度的特定 UE。 应理解， 本发明实施例对 此并不限定。
可选地， 作为另一个实施例， 基站对特定 UE执行优先调度可以是增加 特定 UE的调度资源分配和 /或增加特定 UE的调度频率。 例如， 按照原有的 调度算法， 基站平均每秒对特定 UE的调度次数为 n, 采用优先调度算法后， 基站平均每秒对特定 UE的调度次数为 m, m>n。 又例如， 按照原有的调度 算法， 特定 UE的调度资源为总调度资源的 10%, 采用优先调度算法后， 特 定 UE的调度资源为总调度资源的 30%。 因此， 特定 UE分配到更多的调度 资源。 这样， 能够有效地改善特定 UE的性能， 提高特定 UE的吞吐量。
应理解， 上述特定 UE的调度资源占总调度资源的比例取值仅仅是示例 性的， 而非对本发明的限制。 还应理解， 本发明实施例对特定 UE采用何种 优先调度算法并不限定。
另外， 基站可以将调度的信息发送给相应的 UE, 例如， 基站可以通过 E-AGCH ( E-DCH Absolute Grant Channel，增强型专用信道的绝对授权信道） 或者 E-RGCH ( E-DCH Relative Grant Channel, 增强型专用信道的相对授权 信道 )将调度资源的信息发送给特定 UE。
下面结合具体实施例， 更加详细地描述本发明实施例的调度方法的非限 本发明实施例， 而非要限制本发明的范围。 图 4至图 7是本发明实施例的可 适用于图 1的网络系统的调度方法的过程的示意性流程图。在图 4至图 7中， 以 WCDMA 系统为例进行说明。 应理解， 本发明实施例并不限于此， 可以 为 WCDMA 系统之外的其它移动通信系统。 还应注意的是， 本发明实施例 对于优先调度是上行调度还是下行调度， 以及特定 UE的服务小区为宏基站 还是微基站并不限定。 基站除了上述宏基站和微基站， 还可以是其它类型的 基站， 如微微基站、 毫微微基站、 中继站等。
图 4是本发明一个实施例的调度方法的过程的示意性流程图。 图 4的方 法适用于服务小区为宏基站的特定 UE的上行优先调度。
401 , 宏基站控制器确定启用特定 UE的优先调度。
例如， 如果处于宏小区和微小区软切换区域且服务小区为微基站的 UE 个数大于某个阈值， 则宏基站控制器可以确定启用 HSUPA 或者 E-HSUPA 特定 UE的优先调度。 又例如， 如果在宏小区和微小区软切换区域存在服务 小区为宏基站的 UE,则宏基站控制器可以确定启用 HSUPA特定 UE的优先 调度。 应理解， 本发明实施例对此不作限定。
402, 宏基站控制器向宏基站发送指示信息。
例如， 宏基站控制器可以向宏基站发送信令消息， 信令消息携带指示信 息。 具体地， 宏基站控制器可以通过 lub接口， 在 NBAP现有的消息（例如 系统消息更新请求消息） 中增加一个 IE 指示宏基站启用 HSUPA 或者 E-HSUPA特定 UE的优先调度。 应理解， 本发明实施例并不限于此， 宏基站 控制器还可以新增加一条 NBAP消息作为指示消息，或者通过隐式的方式通 知该指示信息。
又例如， 宏基站控制器可以向宏基站发送用户面数据帧， 用户面数据帧 携带指示信息。 具体地， 宏基站控制器可以通过 lub接口下行数据帧 （例如 HS-DSCH数据帧类型 1 )中增加一个标记 flag指示宏基站启用 HSUPA或者 E-HSUPA特定 UE的优先调度。
应注意， 本发明实施例对于宏基站控制器发送指示信息的形式并不限 定。
403, 宏基站确定特定 UE, 并对特定 UE执行优先调度。
例如， 宏基站在步骤 402中收到指示信息， 宏基站可以根据 UE的参数 值确定特定 UE。 参数值可以包括但不限于： CQI值、 SIR、 SI等。 应理解， 本发明实施例对此并不限定。 具体地， UE在物理层上报的 CQI值和 /或 UE MAC层上报的 SI低于相应的阈值， 宏基站可以确定该 UE为需要进行优先 调度的特定 UE。 这样， 能够有效地提高网络调度的灵活性。
可选地， 宏基站对特定 UE执行优先调度可以是增加特定 UE的调度资 源分配和 /或增加特定 UE的调度频率。 例如， 按照原有的调度算法， 宏基站 平均每秒对特定 UE的调度次数为 n, 采用优先调度算法后， 宏基站平均每 秒对特定 UE的调度次数为 m, m>n。 又例如， 按照原有的调度算法， 特定 UE的调度资源为总调度资源的 10%, 采用优先调度算法后， 特定 UE的调 度资源为总调度资源的 30%。 因此，特定 UE分配到更多的调度资源。这样， 能够有效地改善特定 UE的性能， 提高特定 UE的吞吐量。
应理解， 上述特定 UE的调度资源占总调度资源的比例取值仅仅是示例 性的， 而非对本发明的限制。 还应理解， 本发明实施例对特定 UE采用何种 优先调度算法并不限定。

701 , 微基站控制器确定启用特定 UE的优先调度。
如果 UE在选择服务小区时采用了扩展小区覆盖的方案， 则微基站控制 器可以确定启用 HSDPA或者 E-HSDPA特定 UE的优先调度。 例如， 如果 UE在选择服务小区时采用了偏置值， 则基站控制器可以确定启用特定 UE 优先调度。 具体地， 某个 UE测量到宏小区的信号比微小区的信号强， 如果 没有设置正偏置值， UE 的服务小区应为宏小区。 但是， 在不增加微小区的 发射功率的前提下， 为了达到提高微小区覆盖的目的， UE在选择服务小区 过程中， 在测量的微小区信号值上再加上一个信号正偏置值。 这样， UE检 测得到微小区的信号比宏小区的信号强， 因此， UE选择微小区作为服务小 区。 如果 UE在选择服务小区时， 微小区信号采用了信号正偏置值， 微小区 的覆盖范围被扩展了，微基站控制器可以确定启用 HSDPA或者 E-HSDPA特 定 UE的优先调度。 应理解， 本发明对此并不限定， 即无论是在微小区采用 了偏置值还是宏小区采用了偏置值， 以及何种原因引入偏置值均落入本发明 的范围内。 还应理解， UE在选择服务小区时采用了其他扩展小区覆盖的方 案， 也可以作为启用优先调度的依据。 还应理解， UE在选择服务小区时采 用了其他扩展小区覆盖的方案， 也可以作为启用优先调度的依据。
