无线网络信息管理单元 22, 用于根据测量控制单元 21接收的无线网络 信息确定需要触发的无线网络功能和所述无线网络功能对应的算法; 将所述 算法所需的无线网络信息封装为所述算法的无线网络信息组合。
具体地,无线网络信息管理单元 22中存储有各网络节点执行各无线网络 功能对应的算法所需的无线网络信息列表, 以及各无线网络功能的触发条件。 当测量控制单元 21接收到网络节点发送的无线网络信息后,无线网络信息管 理单元 22判断是否有无线网络功能到达触发条件, 若是, 则确定需要触发的 无线网络功能对应的算法, 并将达到触发条件的无线网络功能对应算法所需 的无线网络信息封装在一起作为该算法的无线网络信息组合。
这里的无线网络功能包括网络节点在无线网络中进行的各种处理, 例如 UE的切换、 接入节点进行负载均衡、 UE的接入等。 无线网络功能对应的算 法表示对无线网络功能进行处理的具体方法, 通过无线网络功能对应的算法 进行处理后, 得到网络节点完成该无线网络功能所需执行的具体处理流程。 一个无线网络功能可能包括多个算法, 一个算法也可能对应对个无线网络功 能, 例如无线网络功能为接入节点进行负载均衡, 其对应的算法可能包括多 个 UE的切换。
算法管理单元 23, 用于根据无线网络信息管理单元 22封装的无线网络 信息组合确定所述算法的执行策略。
具体地,无线网络信息管理单元 22将封装后的无线网络信息组合发送给 算法管理单元 23, 算法管理单元 23根据该无线网络信息组合进行运算, 得 到的运算结果为各网络节点为了实现该算法对应的无线网络功能所需进行的 处理流程。 并且算法管理单元 23还确定各网络节点的处理流程的执行顺序。 上述处理流程和处理流程的顺序共同称为该算法的执行策略。
流程管理单元 24, 用于根据算法管理单元 23确定的所述执行策略生成 执行控制信令, 向网络节点发送所述执行控制信令, 以使网络节点完成所述 无线网络功能。
具体地, 由于对网络节点进行管理和控制都需要采用信令的方式进行, 因此无线网络控制器还包括流程管理单元 24, 流程管理单元 24中存储有实 现各算法的运算结果所需的执行控制信令,流程管理单元 24根据算法管理单 元 23确定的执行策略生成相应的执行控制信令, 并根据算法管理单元 23确 定的处理流程依次向各网络节点发送执行控制信令。 各网络节点即可根据执 行控制信令的指示执行相应的处理,从而完成无线网络信息管理单元 22确定 需要触发的无线网络功能。
本实施例中, 在网络中加入了无线网络控制器, 该无线网络控制器通过 接收网络中的网络节点发送的无线网络信息确定需要触发的无线网络功能, 并控制各网络节点完成该无线网络功能。由于采用了集中式的无线网络控制, 因此该无线网络控制器可以同时对多种制式的无线网络同时进行控制, 实现 了多网络的集中管理, 从而节约了系统资源。
在图 2所示实施例中,测量控制单元 21用于接收网络节点发送的无线网 络信息。 但在网络中的网络节点有两种工作状态, 第一种是已经接入网络, 在向测量控制单元 21发送无线网络信息时, 根据接入时测量控制单元 21的 指示发送无线网络信息; 第二种是网络节点新接入网络, 此时测量控制单元 21会先接收到网络节点发送的接入请求消息, 当接收到接入请求消息后, 测 量控制单元 21将控制网络节点进行无线网络信息的测量和上报。
可选的, 测量控制单元 21可以预设有无线网络信息测量配置, 其中无线 网络信息测量配置包括测量的执行实体、 测量对象和上报周期, 也就是说无 线网络信息测量配置中包括 "让谁测" 、 "测什么" 、 "如何上报"几种信 息。测量控制单元 21在接收到网络节点发送的接入请求消息后, 査询预设的 无线网络信息测量配置, 获知该网络节点是新接入网络的, 并根据接入请求 消息中该网络节点的相关信息确定该网络节点对无线网络信息进行测量和上 报的规则。然后测量控制单元 21可以生成相应的测量控制信令, 并向网络节 点发送测量控制信令, 从而实现对网络节点进行无线网络信息的测量和上报 的控制。
可选的, 测量控制单元 21还可以不存储无线网络信息测量配置, 而是在 接收到接入请求消息后,将该接入请求消息通知给无线网络信息管理单元 22。 在无线网络信息管理单元 22 中保存有已接入的网络节点列表以及无线网络 信息测量配置, 无线网络信息管理单元 22根据测量控制单元 21发送的接入 请求消息确定该网络节点的无线网络信息测量配置, 并将其发送给测量控制 单元 21 ; 测量控制单元 21根据无线网络信息管理单元 22确定的无线网络信 息测量配置生成相应的测量控制信令, 并向网络节点发送测量控制信令, 从 而实现对网络节点进行无线网络信息的测量和上报的控制。
或者还有一种实现方式,测量控制单元 21中存储有无线网络信息测量配 置, 但该无线网络信息测量配置中不包括已接入网络节点列表, 测量控制单 元 21接收到接入请求消息后,还是需要将接入请求消息发送给无线网络信息 管理单元 22。 无线网络信息管理单元 22中包括已接入网络节点列表, 当无 线网络信息管理单元 22确定发送该接入请求消息的网络节点是新接入的时, 通知测量控制单元 21, 测量控制单元 21再根据存储的无线网络信息测量配 置生成相应的测量控制信令, 并向网络节点发送测量控制信令, 从而实现对 网络节点进行无线网络信息的测量和上报的控制。
图 3为本发明实施例提供的无线网络控制器中测量控制单元的结构示意 图, 如图 3所示, 本实施例的测量控制单元 21包括:
无线网络信息测量配置管理子单元 31, 用于根据无线网络信息测量配置 生成测量信令流程调用信息。
具体地,无线网络信息测量配置管理子单元 31中存储有无线网络信息测 量配置, 当测量控制单元 21接收到接入请求消息后, 无线网络信息测量配置 管理子单元 31 根据无线网络信息测量配置生成测量各无线网络信息所需信 令的调用信息。
测量控制信令管理子单元 32, 用于根据无线网络信息测量配置管理子单 元 31生成的测量信令流程调用信息调用预设的网络节点测量控制信令。
具体地, 无线网络控制器对网络节点进行控制均采用信令的方式进行, 测量控制信令管理子单元 32中存储有调用各网络节点进行测量的信令。测量 控制信令管理子单元 32根据无线网络信息测量配置管理子单元 31生成的测 量信令流程, 依次地调用预设的各测量控制信令。
测量控制信令处理及分发子单元 33, 用于向所述网络节点发送所述测量 控制信令管理子单元 32调用的测量控制信令;接收所述网络节点发送的无线 网络信息。
具体地,测量控制信令处理及分发子单元 33将测量控制信令管理子单元
32调用的各测量控制信令依次发送至相应的网络节点, 从而使网络节点进行 无线网络信息的测量。并且测量控制信令处理及分发子单元 33还用于接收各 网络节点发送的无线网络信息。
图 4为本发明实施例提供的无线网络控制器中无线网络信息管理单元的 结构示意图, 如图 4所示, 本实施例的无线网络信息管理单元 22包括: 无线网络信息管理子单元 41, 用于存储测量控制单元 21接收的无线网 络信息。
具体地,在无线网络信息管理单元 22中设置有无线网络信息管理子单元 41, 无线网络信息管理子单元 41用于存储测量控制单元 21接收的无线网络 信息。测量控制单元 21接收到的无线网络信息都会存储在无线网络信息管理 子单元 41中, 当测量控制单元 21接收到的无线网络信息已经存储在无线网 络信息管理子单元 41中, 侧无线网络信息管理子单元 41将更新已存储的无 线网络信息。
在无线网络信息管理单元 22中设置无线网络信息管理子单元 41是由于, 网络节点向测量控制单元 21发送的无线网络信息的上报周期可能各有不同, 测量控制单元 21并不是随时都会从网络节点接收到所有的无线网络信息,而 当无线网络信息管理单元 22接收到无线网络信息后,确定触发某一无线网络 功能时, 该无线网络功能对应的算法需要的无线网络信息可能并没有被测量 控制单元 21接收到,这样可能导致无法生成需要触发的无线网络功能对应算 法的无线网络信息组合。因此在无线网络信息管理单元 22中设置无线网络信 息管理子单元 41, 根据测量控制单元 21接收到的无线网路信息更新无线网 络信息管理子单元 41 中的信息, 这样可以保证无线网络信息管理子单元 41 中的信息是完整的, 可以确保能够生成相应的无线网络信息组合。
无线网络功能触发管理子单元 42, 用于当无线网络信息管理子单元 41 存储的无线网络信息中的至少一个无线网络信息达到预设的触发条件时, 根 据预设的无线网络功能触发列表, 确定需要触发的无线网络功能和所述无线 网络功能对应的算法。

具体地,无线网络信息管理单元 22中还包括无线网络功能需求管理子单 元 43, 无线网络功能需求管理子单元 43 中存储有无线网络功能对应算法所 需的无线网络信息列表。当无线网络功能触发管理子单元 42确定需要触发的 无线网络功能和所述无线网络功能对应的算法后, 无线网络功能需求管理子 单元 43 将需要触发的算法所需的无线网络信息从无线网络信息管理子单元 41中调出, 并封装为该算法的无线网络信息组合。
图 5为本发明实施例提供的无线网络控制器中算法管理单元的结构示意 图, 如图 5所示, 本实施例的算法管理单元 23包括:
算法管理子单元 51, 用于根据无线网络信息管理单元 22封装的无线网 络信息组合选择对应算法完成运算, 生成所述算法的运算结果, 所述运算结 果包括参与所述算法执行的网络节点的执行流程和配置参数。
具体地, 在算法管理子单元 51中存储有各算法的具体运算方法和流程, 当算法管理子单元 51接收到无线网络信息管理单元 22封装的无线网络信息 组合后, 将选择与该无线网络信息组合对应的算法进行运算, 生成运算结果。 算法的运算结果包括参与该算法执行的网络节点的执行流程和配置参数, 也 就是说算法的运算结果包括控制网络节点完成该算法对应的无线网络功能所 需的具体处理方法。
算法流程管理子单元 52, 用于根据算法管理子单元 51 生成的所述算法 的运算结果确定所述算法的执行策略。
具体地, 由于完成一个无线网络功能可能需要多个网络节点进行处理, 因此在无线网络信息管理单元 23 中还可以包括算法流程管理子单元 52。 算 法流程管理子单元 52得到算法管理子单元 51生成的运算结果后, 对执行算 法运算结果的各执行实体进行协调, 最终确定所述算法的执行策略。
图 6为本发明实施例提供的无线网络控制器中流程管理单元的结构示意 图, 如图 6所示, 本实施例的流程管理单元 24包括:
执行控制信令管理子单元 61, 用于根据算法管理单元 23确定的执行策 略生成执行控制信令流程调用信息。

控制信令管理子单元 62, 用于根据执行控制信令管理子单元 61生成的 控制信令流程调用信息调用预设的执行控制信令。
具体地, 由于无线网络控制器对网络节点进行控制均采用信令的方式进 行,控制信令管理子单元 62中存储有调用各网络节点完成各处理流程的控制 信令。 控制信令管理子单元 62根据执行控制信令管理子单元 61生成的控制 信令流程调用信息, 依次地调用预设的各控制信令。

但是对于新加入网络的未知网络节点, 或者新定义的网络制式, 或者新 定义的无线网络功能而言,还需要设置一个机制对无线网络控制器进行配置。 无线网络功能配置模块 25可以调用测量控制单元 21的接口, 对测量控制单 元 21中各算法所需的无线网络信息测量配置进行配置,即定义各算法所需的 执行实体、 测量对象和上报周期等参数。

下面以具体的实施例对本发明实施例提供的无线网络控制器进行详细说 明。 图 14为本发明实施例提供的无线网络控制方法进行 UE切换的具体实现 方法示意图。 如图 14所示, 无线网络控制器 20包括测量控制单元 21、 无线 网络信息管理单元 22、 算法管理单元 23和流程管理单元 24。 网络中的第一 UE131接入第一基站 132, 并且第一 UE131同时位于第二基站 133和第三基 站 134的覆盖范围内。 第一 UE131周期性地对第一基站 132、 第二基站 133、 第三基站 134的小区信号强度进行测量, 并向测量控制单元 21上报; 测量控 制单元 21将接收到的第一 UE131上报的第一基站 132、 第二基站 133、 第三 基站 134的小区信号强度发送至无线网络信息管理单元 22; 无线网络信息管 理单元 22对存储的无线网络信息进行更新, 当发现第一 UE131发送的第一 基站 132的小区信号强度低于预设的门限值时, 则识别到 UE切换处理需要 触发, 并确定切换算法需要第一基站 132、 第二基站 133和第三基站 134的 小区信号强度; 无线网络信息管理单元 22将第一基站 132、 第二基站 133和 第三基站 134的小区信号强度封装在一起并发送给算法管理单元 23 ; 算法管 理单元 23将接收到的封装信息分配给切换算法,切换算法进行运算后确定需 要将第一 UE131从第一基站 132中切换至第二基站 133中, 并将运算结果发 送至流程管理单元 24; 流程管理单元 24调用将第一 UE131从第一基站 132 中切换至第二基站 133中所需的处理流程和控制信令, 并依次顺序控制第一 UE13 第一基站 132和第二基站 133完成切换处理。
