下面分别对 CRRM单元进行集中负载控制、 集中功率控制、 集中切换控制 的具体实现进行描述。
首先，对 CRRM单元根据多制式通信网络中各单制式通信网络的负载情况， 控制终端接入的具体实现进行描述。 CRRM单元主要在三个方面进行集中负载 控制， 分别是前向负载集中控制、 反向负载集中控制和接入信道负载集中控制。
前向负载用于检测前向导频功率， 能够控制终端从其他制式通信网络接入 及接收其他制式网络的导频信号。 前向负载集中控制中， 多制式通信网络中的 某单制式通信网络为终端建立呼叫之前， 该单制式通信网络的无线资源管理单 元先检测本单制式通信网络的前向负载情况， 如前向导频的信噪比 Ec/Io, 如果 本制式通信网络的前向负载较重， 例如 Ec/Io高于设定值， 则该无线资源管理单 元向 CRRM单元发送请求， 并上报当前前向负载信息，请求 CRRM单元为终端 选择前向负载较轻的单制式通信网络。 CRRM单元收到请求后， 确定终端能够 支持的制式， 然后确定终端支持的、 且前向负载轻于发起请求的单制式通信网 络的一种制式的通信网络， 通知终端接入该单制式通信网络， 即终端当前应该 接入的单制式通信网络， 由该单制式通信网络为终端建立呼叫。 CRRM单元可 在除发起请求的单制式通信网络外、 终端支持的制式中根据网络状况随机选择 一种制式的通信网络， 也可根据设定原则确定的选择顺序选择一种制式的通信 网络， 然后将该单制式通信网络的前向负载与发起请求的单制式通信网络的前 向负载进行比较， 如果前者低于后者， 则控制终端接入前向负载较轻的单制式 通信网络， 例如， CRRM单元通知前向负载较轻的单制式通信网络向终端发送 寻呼指示， 以使终端接入该单制式通信网络； 否则， CRRM单元继续选择一种 制式的通信网络进行前向负载比较， 直至确定出前向负载相对较轻的单制式通 信网络供终端接入。 如果终端支持的所有制式的通信网络的前向负载都比较重， 则本次接入失败。 CRRM单元也可对终端支持的所有制式的通信网络的前向负 载进行一次性比较， 从中选出前向负载最轻的单制式通信网络供终端接入。 这 样， 通过 CRRM单元对多制式通信网络中各单制式通信网络的负载进行权衡， 控制终端接入负载相对较轻的单制式通信网络， 以平衡各单制式通信网络的负 载。
反向负载集中控制是对接入的准入进行控制， 用于检测反向接入， 最终终 端能否接入主要取决于反向负载的情况。 反向负载集中控制中， 多制式通信网 络中的某单制式通信网络接入终端之前， 该单制式通信网络的无线资源管理单 元先本单制式通信网络的反向负载情况、 如反向信号强度指示（ Received Signal Strength Indication, RSSI ), RSSI越大说明该单制式通信网络小区的用户数量较 多 （或用户速率较大）或所受干扰较大， 即反向负载较重， 然后该无线资源管 理单元向 CRRM单元发送请求， 并上报当前反向负载信息，请求 CRRM单元为 终端选择反向负载较轻的单制式通信网络。 CRRM单元收到请求后， 确定终端 能够支持的制式， 然后确定终端支持的、 且反向负载轻于发起请求的单制式通 信网络的一种制式的通信网络， 通知终端接入该单制式通信网络， 即终端当前 应该接入的单制式通信网络， 由该单制式通信网络接入该终端。 CRRM单元可 在除发起请求的单制式通信网络外、 终端支持的制式中随机选择一种制式的通 信网络， 也可根据设定原则确定的选择顺序选择一种制式的通信网络， 然后将 该单制式通信网络的反向负载与发起请求的单制式通信网络的反向负载进行比 较， 如果前者低于后者， 则控制终端接入反向负载较轻的单制式通信网络， 例 如， CRRM单元通知反向负载较轻的单制式通信网络向终端发送寻呼指示， 以 使终端接入该单制式通信网络； 否则， CRRM单元继续选择一种制式的通信网 络进行反向负载比较， 直至确定出反向负载相对较轻的单制式通信网络供终端 接入。 如果终端支持的所有制式的通信网络的反向负载都比较重， 则本次接入 失败。 CRRM单元也可对终端支持的所有制式的通信网络的反向负载进行一次 性比较， 从中选出反向负载最轻的单制式通信网络供终端接入。 这样， 通过 CRRM单元对多制式通信网络中各单制式通信网络的负载进行权衡， 控制终端 接入负载相对较轻的单制式通信网络， 以平衡各单制式通信网络的负载。
接入信道用于反向链路， 支持呼叫发起、 寻呼响应、 命令消息、 注册及短 消息服务等， 终端使用时隙化的随机接入协议接入。 接入信道在某些情况下可 能有很高的通过量， 由于接入信道发射功率开环控制的存在， 大量的终端同时 接入通信网络会在反向链路产生较大的干扰， 最终导致小区接收功率的增加和 反向链路容量的减少。
CRRM单元进行接入负载集中控制的目的是及时发现某单制式通信网络的 接入负载异常情况， 并对终端接入多制式通信网络中的具体单制式通信网络的 接入参数进行控制和调整， 使得终端能够正常接入其支持的单制式通信网络， 提高终端的接入率， 同时保证各单制式通信网络的容量。 接入负载集中控制是 在接入过程中控制终端接入请求的尝试的平均持续时延， 用来调整接入的间隔 时间， 还可以控制接入的编码速率等。 确切地说， 接入负载集中控制应该是对 接入参数的控制和调整。
接入信道负载集中控制中， CRRM单元根据各单制式通信网络的无线资源 管理单元上报的负载信息及接入参数信息， 确定某单制式通信网络进入高接入 负荷情况， 此时， CRRM单元可控制终端在该终端支持的、 负载相对较轻的单 制式通信网络中实现接入， 例如， CRRM单元通知反向负载较轻的单制式通信 网络向终端发送寻呼指示， 以使终端接入该单制式通信网络， 并在该单制式通 信网络中实现接入。 如果多制式通信网络中的各单制式通信网络的接入负荷均 很高， 则 CRRM单元根据单制式通信网络的负载信息对单制式通信网络的接入 参数进行调整， 如降低接入速率， 从而降低接入信道负荷， 提高多制式通信网 络高接入负荷异常情况下， 终端的接入成功率， 使得多制式通信网络更为稳定。 多制式通信网络中的单制式通信网络的接入负荷降低后， CRRM单元可将该单 制式通信网络的接入参数恢复至接入负荷正常情况下的接入参数。 接入参数可 为接入请求的平均持续时延、 接入速率、 编码方式等。
其次， 对 CRRM单元根据多制式通信网络中各单制式通信网络的负载情况 进行外环功率微调的具体实现进行描述。
载频前向的 FER用于描述通话质量， 如果 FER高， 则说明通信质量不好； 如果 FER低， 则说明通话质量良好。 FER高时， 可提高准入门限， 通信网络通 过限制终端的接入来提高通话质量； FER低时， 可降低准入门限， 在保证通信 质量的前提下允许更多的终端接入通信网络。 准入门限用于控制终端接入通信 网络， 即终端的准入高于准入门限时， 允许终端接入通信网络， 终端的准入低 于准入门限时， 拒绝终端接入通信网络。
图 4为本发明实施例三中 CRRM单元调整 FER流程图，如图 4所示， CRRM 单元根据多制式通信网络中各单制式通信网络的负载情况调整 FER的具体处理 过程包括以下步骤：
步骤 401〜步骤 402: 某单制式通信网络中的基站向无线资源管理单元上报 FER设定值， 无线资源管理单元收到 FER设定值后， 向 CRRM单元上报 FER 设定值。
步骤 403: CRRM单元收到 FER设定值后， 根据多制式通信网络中各单制 式通信网络的负载情况， 对 FER设定值进行调整， 然后向无线资源管理单元返 回调整后的 FER设定值。
步骤 404: 无线资源管理单元收到调整后的 FER设定值后， 向基站返回调 整后的 FER设定值。
由于发射功率过大， 会对其他单制式通信网络造成干扰， 因此， 进一步地， 基站可根据调整后的 FER通知终端调整发射功率门限， 终端收到通知后， 对发 射功率门限进行调整， 使得该单制式通信网络对其他单制式通信网络的干扰在 合理范围内。
再次， 对 CRRM单元根据多制式通信网络中各单制式通信网络的负载状况 进行集中切换控制的具体实现进行描述。
通过多制式通信网络中设置的 CRRM单元能够实现多制式通信网络中各单 制式通信网络之间的异频切换， 可通过伪导频技术或直接切换技术来实现。
伪导频技术是指多制式通信网络中的某单制式通信网络 A的频率为 F1 , 另 一单制式通信网络 B的频率是 F2, 由于终端对异频强度测量的问题， 为避免终 端由 A切换至 B的盲目性， 网络规划时， 在 B中配置与 A相同的导频 F1 , 但 导频 F1只具有导频信道等公共信道， 没有任何的业务信道， 将 B中配置的 F1 称为伪目标制式导频或导频信标。 B中， 由于导频 F1与 F2的导频覆盖范围相 同， 因此， 终端通过对导频 F1的测量， 能够比较准确地获知 F2的导频强度， 以保证切换的准确性。 A和 B可为相同制式、 不同频率的单制式通信网络。 如 果终端驻留在 A中， 当 CRRM单元根据 A和 B的负载情况确定终端需要由 A 切换至 B时， 可通过伪导频技术使终端由 A切换至 B。
直接切换技术是指 CRRM单元确定根据多制式通信网络中各单制式通信网 络的负载情况确定终端需要进行切换时， 例如， 将终端由 A切换至 B, CRRM 单元控制 A中的基站控制单元断开与终端的连接， 然后指示 B中的基站控制单 元与终端建立连接， 实现终端由 A至 B的切换。 所述基站控制单元可在无线资 源管理单元中实现。 综上所述， 本发明各实施例提供的方案中， 在多制式通信网络中引入了
CRRM单元， 实现对多制式通信网络的无线资源进行统一管理， 全面掌握多制 式通信网络的负载情况和系统运行状况， 实现了对多制式通信网络无线资源的 实时控制和统一优化， 最大程度地利用了多制式通信网络的无线资源， 保护了 运营商的投资。 CRRM单元能够对多制式通信网络进行统一的网络规划和实时 的参数控制和调整， 实现跨无线接入制式间的接入及切换控制。
在多制式通信网络中引入 CRRM单元后， 可以从多制式通信网络的整体来 确定最优的功率控制参数， 从而实现对多制式通信网络中各单制式通信网络功 率控制的再调节。
在多制式通信网络中引入 CRRM单元后， 可以从多制式通信网络整体来确 定各单制式通信网络的负载情况， 从而实现对整个多制式通信网络的接入控制 和接入重定向， 最合理的利用无线资源。
在多制式通信网络中引入 CRRM单元后， 可以实现多制式通信网络中各单 制式通信网络之间的异频硬切换， 最充分地利用了无线资源， 并最大程度地满 足用户的业务体验。 离本发明的精神和范围。 这样， 倘若本发明实施例中的这些修改和变型属于本 发明权利要求及其等同技术的范围之内， 则本发明实施例也意图包含这些改动 和变型在内。
