实施例 1
本发明实施例提供一种负载补偿方法, 应用于补偿小区与节能小区 联合服务的通信系统中。 以下在补偿小区的基站侧, 对所述方法进行详 细说明。
图 1是本发明实施例的负载补偿方法的一流程图, 如图 1所述, 所 述方法包括:
步骤 101,补偿小区的基站根据节能小区的用户设备测量到的补偿小 区的信号质量, 获得节能小区的用户设备在补偿小区中所需的资源估计 值;
步骤 102,补偿小区的基站根据节能小区的用户设备在补偿小区中所 需的资源估计值, 确定是否对节能小区进行补偿;
步骤 103,补偿小区的基站在确定对节能小区进行补偿后,提高相关 资源的功率对节能小区进行补偿。
在本实施例中, 在步骤 102 的补偿决策步骤确定对节能小区进行补 偿之后, 所述方法还可以包括: 去激活回复步骤, 向节能小区的基站发 送去激活回复消息, 该去激活回复消息包括用于补偿的资源信息。
由此, 节能小区的基站可以根据去激活回复消息将节能小区的用户 设备切换到补偿小区, 并关闭节能小区。 根据节能小区的用户设备在补 偿小区中所需的资源估计值, 来确定是否对节能小区进行补偿; 可以反 映出将占用补偿小区的资源, 提高负载补偿的准确性。
在一个实施例中, 在实施步骤 101 时, 补偿小区的基站可以接收节 能小区的基站发送的去激活请求消息, 该去激活请求消息包括节能小区 的用户设备测量到的补偿小区的信号质量; 补偿小区的基站根据该节能 小区的用户设备测量到的补偿小区的信号质量, 估计得到资源估计值。
具体地, 节能小区的用户设备可测量补偿小区的信号质量, 可将该 补偿小区的信号质量发送给节能小区的基站。 至于如何测量补偿小区的 信号质量, 可以采用本发明后面所述的用于负载估计的测量方法; 但不 限于此, 还可以根据实际情况采用其他的测量方式。
然后, 节能小区的基站可以向补偿小区的基站发送去激活请求消息, 该去激活请求消息包括节能小区的用户设备测量到的补偿小区的信号质 量。 补偿小区的基站接收到该去激活请求消息后, 可以根据该节能小区 的用户设备测量到的补偿小区的信号质量, 进行负载估计以得到资源估 计值。
在具体实施时, 在一个实施例中, 补偿小区的基站可以采用如下公 式对节能小区的每个用户设备进行负载估计:
BWESlog2 (l + SINRES) = BWCPlog2 (l + SINRCP) ;
其中, BWES表示节能小区的用户设备在节能小区占用的资源, BWCP表 示节能小区的用户设备在补偿小区中占用的资源, SINRES表示节能小区的 用户设备测量的节能小区的信号质量, SINR CP表示节能小区的用户设备测 量的补偿小区的信号质量。
在具体实施时, BWE^PSINRES可以采用现有技术获得。 由此, 在得到 SINRcp的情况下可以计算 BWeP, 从而获得节能小区的用户设备在补偿小区 中所需的资源估计值。
进一步地, 可以将节能小区的所有用户的资源估计值求和, 就可以 得到节能小区的所有用户所占用的补偿小区的总资源估计值, 通过该总 资源估计值可以确定是否对节能小区进行补偿。
在另一个实施例中, 进行资源估计具体可以包括: 根据节能小区的 用户设备所测量到的补偿小区的信号质量, 估计出用户设备在补偿小区 中所需采用的调制编码方式; 并根据调制编码方式估计在补偿小区中占 用的资源。
在具体实施时, 在估计出用户设备在补偿小区中所需采用的调制编 码方式之后, 可以同时根据每个用户设备的业务状况估计在补偿小区中 所需占用的资源。 至于如何估计调制编码方式等具体实现, 可采用现有 技术, 此处不再赘述。
此外, 该去激活请求消息还可以包括: 节能小区当前的能量消耗和 节能小区的用户的 QoS信息等等。 其中, 节能小区当前的能量消耗例如 可为每比特所消耗的能量, 该比特可以是应用层的比特, 也可以是物理 层的比特; 节能小区的用户的 QoS信息例如可为每个用户的业务类型, QoS要求等。 由此, 通过这些信息, 补偿小区的基站还可以确定提高哪些 相关资源的功率对节能小区进行补偿, 进一步提高补偿的性能和准确性。
图 2是本发明实施例中负载补偿方法的一信令示意图。如图 2所示, 首先, 补偿小区的基站接收节能小区的基站发送的去激活请求消息, 该 去激活请求消息包括节能小区的用户设备测量到的补偿小区的信号质量, 可选地还可以包括节能小区当前的能量消耗和节能小区的用户的 QoS信 息等; 补偿小区的基站根据该消息中的节能小区的用户设备测量到的补 偿小区的信号质量, 可以估计出节能小区的用户设备在补偿小区中所需 的资源估计值。
其次, 补偿小区的基站根据该节能小区的用户设备在补偿小区中所 需的资源估计值、以及节能小区当前的能量消耗和节能小区的用户的 QoS 信息等, 可以确定是否对节能小区进行补偿。
再次, 补偿小区的基站在确定对节能小区进行补偿后, 可以向节能 小区的基站发送去激活回复消息, 使得节能小区根据该去激活回复消息 将其服务的用户设备切换到补偿小区; 并且, 补偿小区的基站可以提高 相关资源的功率对节能小区进行补偿。
在另一个实施例中, 在实施步骤 101 时, 补偿小区的基站可以接收 节能小区的基站发送的去激活请求消息, 该去激活请求消息包括资源估 计值, 该资源估计值由节能小区的基站根据节能小区的用户设备测量到 的补偿小区的信号质量估计得到。
具体地, 该资源估计值可以由节能小区的基站估计得到, 可以采用 如上所述的两种资源估计的方式, 此处不再赘述。
图 3是本发明实施例中负载补偿方法的另一信令示意图。 如图 3所 示,首先,补偿小区的基站接收节能小区的基站发送的去激活请求消息; 该去激活请求消息包括节能小区的用户设备在补偿小区中所需的资源估 计值, 可选地还可以包括节能小区当前的能量消耗和节能小区的用户的
QoS信息等。
其次, 补偿小区的基站根据该节能小区的用户设备在补偿小区中所 需的资源估计值、以及节能小区当前的能量消耗和节能小区的用户的 QoS 信息等, 可以确定是否对节能小区进行补偿。
再次, 补偿小区的基站在确定对节能小区进行补偿后, 可以向节能 小区的基站发送去激活回复消息, 使得节能小区根据该去激活回复消息 将其服务的用户设备切换到补偿小区; 并且, 补偿小区的基站可以提高 相关资源的功率对节能小区进行补偿。
以上对如何进行负载补偿进行了详细说明。 其中, 节能小区当前的 能量消耗和节能小区的用户的 QoS信息等只是可选地信息, 并不是必需 的。在具体实施时,还可以根据实际情况采用更多的信息进行补偿决策, 使得决策更加准确。 值得注意的是: 对于负载的估计可以在补偿小区的 基站侧进行, 也可以在节能小区的基站侧进行。
以下对如何进行用于负载估计的测量进行详细说明。
在本实施例中, 在步骤 101 的估计值获取步骤之前, 所述方法还可 以包括: 探测实现步骤, 补偿小区的基站通过提高一个或多个子帧的发 射功率进行探测, 使得节能小区的用户设备根据一个或多个子帧测量补 偿小区的信号质量。 在具体实施时, 补偿小区的基站可以提高一个或多个子帧的整个子 帧的发射功率、 或者可以提高一个或多个子帧中部分资源的发射功率。
图 4是本发明实施例中提高整个子帧发射功率的示意图, 图 5是本 发明实施例中提高子帧中部分资源的发射功率的示意图。 如图 4和 5所 示, 根据补偿小区的基站的自身资源调度, 这些高功率的子帧可以是周 期性的、 非周期性的或连续的。 但不限于此, 可根据实际情况确定具体 的实施方式。
在具体实施时, 节能小区的基站可以选择性地避免在这些子帧中调 度用户设备, 同时可以配置在这些子帧中的测量, 从而其服务的用户设 备可以评估补偿小区的信号质量, 例如信噪比(SINR)、 参考信号接收质 量 (RSRQ) 等。
节能小区的用户设备在得到测量结果后, 将测量结果发送给节能小 区的基站。 可以由节能小区的基站进行负载估计, 也可以由补偿小区的 基站进行负载估计, 可如上所述, 此处不再赘述。
为了更好地设置基站探测功能, 可以在补偿小区的基站和节能小区 的基站之间进行信令交互, 可以由补偿小区的基站通知节能小区的基站 会提高哪些子帧的功率来进行负载估计。
在具体实施时, 在一个实施例中, 信令流程可以由节能小区的基站 发起。 补偿小区的基站接收节能小区的基站发送的探测请求消息, 该探 测请求消息包括节能小区的基站可接受的探测资源; 补偿小区的基站反 馈探测回复消息给节能小区的基站, 该探测回复消息包括补偿小区的基 站用于探测的资源。
图 6是本发明实施例中探测的一信令示意图。 如图 6所示, 首先, 节能小区的基站向补偿小区的基站发送一个探测请求消息, 在这个探测 请求中, 可选的包含可接受的用于探测的资源, 例如节能小区中没有使 用的资源。 其次, 补偿小区的基站收到这个请求消息后, 可以反馈一个 探测回复消息, 在这个消息中指示补偿小区中用于探测的资源, 可选的 包含探测时间以及探测开始的时延。
其中, 该探测时间可以指明探测持续的时间; 该探测开始的时延可 以用于保证补偿小区增加功率与节能小区的用户设备开始测量能够同时 进行。
在具体实施时, 在另一个实施例中, 信令流程还可以由补偿小区的 基站发起。 补偿小区的基站向节能小区的基站发送探测请求消息, 该探 测请求消息包括补偿小区的基站用于探测的资源; 补偿小区的基站接收 节能小区的基站反馈的探测回复消息, 该探测回复消息包括节能小区的 基站可接受的探测资源。
图 7是本发明实施例中探测的另一信令示意图。如图 7所示,首先, 补偿小区的基站向节能小区的基站发送一个探测请求消息, 在这个请求 中会指示补偿小区中用于探测的资源。 然后, 节能小区会反馈一个探测 回复消息, 在这个回复消息中会指示可接受的补偿小区所采用的探测资 源, 可选的包含探测时间以及探测开始的时延。
以上仅为对基站探测信令的示意性说明, 但不限于此, 例如可以不 使用探测请求回复消息, 直接从探测请求消息中包含的探测资源信息中 决定探测资源; 还可以不使用信令进行探测的交互, 可以预先设置预定 的时间或者资源等, 可根据实际情况确定具体的实施方式。
本发明实施例还提供一种补偿小区的基站, 应用于补偿小区与节能 小区联合服务的通信系统中。 图 8 是本发明实施例中基站的一构成示意 图, 如图 8所示, 该补偿小区的基站包括: 估计值获取器 801、 补偿决策 器 802和负载补偿器 803。
其中, 估计值获取器 801用于根据节能小区的用户设备测量到的补 偿小区的信号质量, 获得节能小区的用户设备在补偿小区中所需的资源 估计值; 补偿决策器 802用于根据节能小区的用户设备在补偿小区中所 需的资源估计值, 确定是否对节能小区进行补偿; 负载补偿器 803 用于 在补偿决策器 802确定对节能小区进行补偿后, 提高相关资源的功率对 节能小区进行补偿。
在一个实施例中, 估计值获取器 801具体可以包括: 去激活请求接 收器。 该去激活请求接收器用于接收节能小区的基站发送的去激活请求 消息, 该去激活请求消息包括资源估计值, 该资源估计值由节能小区的 基站根据节能小区的用户设备测量到的补偿小区的信号质量估计得到。
在另一个实施例中, 估计值获取器 801 具体可以包括: 去激活请求 接收器和资源估计器。 其中, 去激活请求接收器用于接收节能小区的基 站发送的去激活请求消息, 该去激活请求消息包括节能小区的用户设备 测量到的补偿小区的信号质量; 资源估计器用于根据节能小区的用户设 备测量到的补偿小区的信号质量, 估计得到资源估计值。
