本发明的较佳实施方式 本发明的发明构思是: 基站实时地或周期性地统计空中接口资源的占用
情况; 当用户设备(UE )发起业务请求时, 所述基站根据所述空中接口资源 的占用情况, 确定是否允许接入所述 UE发起的业务。 具体地, 基站预先保存空中接口参数, 所述空中接口参数用于表示所述 基站上空中接口资源的签约情况信息 ,其作为基站确定是否允许接入所述 UE 发起的业务的参考之一, 根据运营商与接入网签约方式的不同, 基站所保存 的空中接口参数的内容也不同。 签约方式为以下三种之一: 方式一, 基站上一个或多个运营商分别签约租用固定大小的空中接口资 源, 即一个或多个运营商均有自己的专用空中接口资源, 不提供共享的空中 接口资源; 针对签约方式一, 基站上的空中接口参数包括: 独享或共享该基站的运 营商所签约的空中接口资源大小信息, 即一个或多个运营商的专用空中接口 资源。 方式二, 基站上一个或多个运营商分别签约租用固定大小的空中接口资 源, 并将其中的一部分空中接口资源作为共享空中接口资源, 允许其他运营 商租用该共享空中接口资源, 即一个或多个运营商签约的空中接口资源包括 专用空中接口资源和共享空中接口资源; 所有空中接口资源中的共享空中接 口资源共同组成共享空中接口资源池; 不排除有多个运营商时, 一部分运营 商提供共享空中接口资源, 而另一部分运营商不提供共享空中接口资源的情 况; 针对签约方式二, 基站上的空中接口参数包括以下几组参数中的任意一 组:
•独享或共享所述基站的运营商所签约的空中接口资源大小信息以及运 营商所签约的空中接口资源中可供其他运营商共享的共享空中接口资源大小 信息;
•独享或共享所述基站的运营商所签约的空中接口资源大小信息以及各 运营商所签约的空中接口资源中供自己专用的专用空中接口资源大小信息;
*独享或共享所述基站的运营商所签约的空中接口资源中可供其他运营 商共享的共享空中接口资源大小信息以及供自己专用的专用空中接口资源大 小信息;
*独享或共享所述基站的运营商所签约的空中接口资源大小信息、 运营 商所签约的空中接口资源中可供其他运营商共享的共享空中接口资源大小信 息以及供自己专用的专用空中接口资源大小信息。 方式三, 基站预留一部分空中接口资源作为共享空中接口资源, 即组成 共享空中接口资源池, 基站上一个或多个运营商分别签约除共享空中接口资 源外的空中接口资源作为各自的专用空中接口资源。 针对签约方式三, 基站上的空中接口参数包括: 独享或共享所述基站的 运营商所签约的空中接口资源大小信息以及基站预留的共享空中接口资源大 小信息。
基站实时或周期性统计空中接口资源的占用情况, 将其作为确定是否允 许接入 UE发起的业务的另一参考条件。 具体地, 基站根据独享或共享该基 站的运营商正在进行的业务, 对该一个或多个运营商占用的空中接口资源进 行实时地或周期性地统计。 基站根据实时或周期性统计的结果以及预先保存的空中接口参数对独享 或共享该基站的运营商的空中接口资源进行限制, 以避免某个运营商占用空 中接口资源过多而导致其他运营商下用户业务质量受损。 所述基站根据所述空中接口资源的占用情况确定是否允许接入所述 UE 发起的业务的步骤包括: 基站将该 UE所属运营商的剩余空中接口资源与待 接入业务预计需要的空中接口资源进行比较, 如果该运营商剩余空中接口资 源能够满足所述业务接入, 则允许接入 UE发起的业务, 如果该运营商剩余 空中接口资源不能满足所述业务接入, 则业务建立失败。 优选地, 当该运营商剩余空中接口资源不能满足所述业务接入时, 进一 步判断是否有剩余共享空中接口资源, 如果有, 则判断剩余共享空中接口资 源是否能够满足所述业务接入, 如果是, 则允许接入 UE发起的业务, 如果
判断没有剩余共享空中接口资源, 或者如果剩余共享空中接口资源不能够满 足所述业务接入, 业务建立失败。 该共享空中接口资源可能是一个或多个运 营商提供的, 也可能是基站提供的。 进一步地, 所述 UE所属运营商的剩余空中接口资源通过以下方法之一 获得:
1 )基站周期性地计算该运营商的剩余空中接口资源并保存, 当 UE发起 业务时, 基站通过查询获得该运营商最新的剩余空中接口资源;

下面结合附图和具体实施例对本发明作进一步说明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。 如图 2所示, 运营商 A与运营商 B共享接入网, 运营商 A下当前有 3 个用户: UEa、 UEb和 UEc, 运营商 B下当前也有 3个用户: UE1、 UE2和 UE3。 实施例 1是运营商和基站釆用第一种签约方式签约时, 资源接纳控制 的示例; 实施例 2是运营商和基站釆用第二种签约方式签约时, 资源接纳控 制的示例; 实施例 3是运营商和基站釆用第三种签约方式签约时, 资源接纳 控制的示例。 实施例 1 运营商 A和运营商 B分别与接入网签约固定大小的空中接口资源,即釆 用上述签约方式一。 eNodeB 根据签约内容配置空中接口参数, 所述空中接 口参数包括独享或共享所述 eNodeB的运营商所签约的空中接口资源大小信 息。 eNodeB 在签约的空中接口资源生效后启动空中接口资源实时或周期性 统计,对运营商 A和运营商 B分别进行空中接口资源占用情况统计。 eNodeB 可周期性地根据空中接口参数和空中接口资源占用情况计算各运营商的可用 空中接口资源, 即剩余空中接口资源。 本实施例的资源接纳控制方法如图 4所示, 包括以下步骤: 步骤 401 : UE3与核心网建立连接, eNodeB检测出 UE3所属的运营商
是运营商 B; eNodeB可以从核心网侧或者 UE侧本身获得 UE所属运营商信息, 例如 通过核心网发送的初始化上下文建立请求中携带的表示该 UE所属运营商信 息的信元, 获知该 UE所属的运营商; 或者, UE在与 eNodeB建立 RRC连 接的过程中,通过 RRC建立请求消息中携带的表示该 UE所属运营商信息的 信元将该 UE所属运营商信息通知给 eNodeB。 步骤 402, UE3发起业务, eNodeB查询出运营商 B的剩余的空中接口 资源;
在本实施例中, eNodeB 周期性计算各运营商剩余空中接口资源, 在用 户设备发起业务时查询。 在其他实施例中, eNodeB也可以实时进行计算。 步骤 403 , eNodeB将运营商 B的剩余空中接口资源与 UE3发起的待接 入业务预计需要的空中接口资源进行比较: 如果该运营商 B剩余的空中接口 资源满足待接入业务的要求, 则接纳该业务并给予资源调度及分配; 如果该 运营商 B剩余的空中接口资源不满足待接入业务的要求, 不予调度。
实施例 2 运营商 A和运营商 B分别与接入网签约固定大小的空中接口资源,并将 一部分空中接口资源作为共享空中接口资源, 允许对方借用, 即釆用上述签 约方式二。 运营商自己决定是否提供共享空中接口资源以及提供多少共享空 中接口资源。 eNodeB 根据签约内容配置空中接口参数, 所述空中接口参数 包括: 独享或共享所述 eNodeB的运营商所签约的空中接口资源大小信息以 及运营商所签约的空中接口资源中可供其他运营商共享的共享空中接口资源 大小信息; 或者包括: 独享或共享所述 eNodeB的运营商所签约的空中接口 资源大小信息以及运营商所签约的空中接口资源中供自己专用的专用空中接 口资源大小信息; 或者包括: 独享或共享所述 eNodeB的运营商所签约的空 中接口资源中可供其他运营商共享的共享空中接口资源大小信息以及供自己 专用的专用空中接口资源大小信息; 或者包括: 独享或共享所述 eNodeB的 运营商所签约的空中接口资源大小信息、 运营商所签约的空中接口资源中可
供其他运营商共享的共享空中接口资源大小信息以及供自己专用的专用空中 接口资源大小信息。 eNodeB 在签约的空中接口资源生效后启动空中接口资 源实时或周期性统计 ,分别统计运营商 A和运营商 B的空中接口资源占用情 况,包括各自专用空中接口资源的占用情况和共享空中接口资源的占用情况。 eNodeB 可周期性计算其上各运营商的剩余空中接口资源, 包括剩余共享空 中接口资源以及剩余专用空中接口资源。 本实施例的资源接纳控制方法如图 5所示, 包括以下步骤: 步骤 501 : UE3与核心网建立连接, eNodeB检测出 UE3所属的运营商 是运营商 B; 步骤 502, UE3发起业务, eNodeB查询运营商 B的剩余空中接口资源, 包括剩余共享空中接口资源以及剩余专用空中接口资源; 步骤 503 , eNodeB将运营商 B的剩余空中接口资源与 UE3发起的待接 入业务预计需要的空中接口资源进行比较: 如果该运营商剩余空中接口资源 满足待接入业务的要求, 则执行步骤 505; 如果该运营商剩余空中接口资源 不满足待接入业务的要求, 则执行步骤 504; 步骤 504, eNodeB查询其他运营商提供的共享空中接口资源池内剩余共 享空中接口资源大小, 在本实施例中 eNodeB查询运营商 A提供的剩余共享 空中接口资源, 判断剩余共享空中接口资源是否满足待接入业务的要求, 如 果满足, 则执行步骤 505; 如果不满足, 则不予调度; 优选地, 在本步骤中, 基站可以综合考虑运营商 B剩余空中接口资源与 其他运营商提供的共享空中接口资源池内的剩余共享空中接口资源, 即判断 运营商 B剩余空中接口资源与剩余共享空中接口资源之和是否满足待接入业 务的要求, 如果满足, 则执行步骤 505 , 如果不满足, 则不予调度。 例如,运营商 A签约 20M空中接口资源,其中的 5M作为共享空中接口 资源, 15M作为专用空中接口资源。 运营商 B签约 15M空中接口资源, 其 中的 5M作为共享空中接口资源, 10M作为专用空中接口资源。 当运营商 B 的空中接口资源仅剩 1M时,运营商 B下的 UE1发起的业务要申请 2M空中 接口资源。基站判断运营商 B的空中接口资源被占用了 19M, 剩余空中接口
资源仅为 1M, 而运营商 A的空中接口资源占用了 18M, 剩余共享空中接口 资源为 2M, 此时, 基站可将运营商 B的 1M剩余空中接口资源和运营商 A 的 1M剩余共享空中接口资源分配给 UE1 , 也可以将运营商 A的 2M剩余共 享空中接口资源分配给 UE1。 步骤 505, 接纳该业务并给予资源调度及分配。
实施例 3 在本实施例中, eNodeB 预留一部分空中接口资源作为共享空中接口资 源,运营商 A和运营商 B分别与接入网签约除共享空中接口资源外的空中接 口资源, 即釆用上述签约方式三。 eNodeB根据签约内容配置空中接口参数, 所述空中接口参数包括: 独享或共享所述 eNodeB的运营商所签约的空中接 口资源大小信息以及预留的共享空中接口资源大小信息。 eNodeB 在签约的 空中接口资源生效后启动空中接口资源实时或周期性统计, 用于统计以下信 息: 其上各运营商的空中接口资源占用情况, 及共享空中接口资源的占用情 况。 eNodeB 可周期性计算剩余空中接口资源, 包括其上各运营商的剩余空 中接口资源以及剩余共享空中接口资源。 本实施例的资源接纳控制方法如图 6所示, 包括以下步骤: 步骤 601 : UE3与核心网建立连接, eNodeB检测出 UE3所属的运营商 是运营商 B; 步骤 602, UE3发起业务, eNodeB查询运营商 B的剩余空中接口资源, 以及剩余共享空中接口资源; 查询剩余共享空中接口资源的步骤也可以在步骤 604中执行。 步骤 603 , eNodeB将运营商 B的剩余空中接口资源与 UE3发起的待接 入业务预计需要的空中接口资源进行比较: 如果该运营商剩余空中接口资源 满足待接入业务的要求, 则执行步骤 605; 如果该运营商剩余空中接口资源 不满足待接入业务的要求, 则执行步骤 604; 步骤 604, eNodeB判断剩余共享空中接口资源是否满足待接入业务的要
求, 如果满足, 则执行步骤 605; 如果不满足, 不予调度; 优选地, eNodeB 可以综合考虑运营商 B 的剩余专用空中接口资源和 eNodeB 提供的剩余共享空中接口资源, 判断上述剩余专用空中接口资源与 剩余共享空中接口资源之和是否满足待接入业务的资源要求, 如果满足, 则 从剩余共享空中接口资源中, 或者从剩余专用空中接口资源和剩余共享空中 接口资源中分配资源给 UE3。 步骤 605 , 接纳该业务并给予资源调度及分配。
上述实施例以两运营商共用接入网为例进行说明, 当有多个运营商共用 接入网时, 资源接纳控制方法相同。 当仅有一个运营商独享接入网时, 也可 釆用上述资源接纳方法。 本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成, 所述程序可以存储于计算机可读存储介质中, 如只读 存储器、 磁盘或光盘等。 可选地, 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地, 上述实施例中的各模块 /单元可以釆用 硬件的形式实现, 也可以釆用软件功能模块的形式实现。 本发明不限制于任 何特定形式的硬件和软件的结合。 当然, 本发明还可有其他多种实施例, 在不背离本发明精神及其实质的 但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
工业实用性 本发明通过对各运营商在***中所占的空中接口资源进行实时或周期性 统计, 进而实现资源接纳控制, 解决了网络共享下的资源调度问题, 保证各 运营商的利益, 避免出现由于某个运营商占用空中接口资源过多而导致其他 运营商下用户业务质量受损或无法接纳的情况, 同时保证了客户的感受, 提 高了用户体验。
