本例中用于宽带网络的资源控制方法主要可包括以下步驟：
步驟 1 : 资源控制模块向 AS进行资源信息注册， 在收到 AS注册成功 的响应后判断注册成功；

步驟 104: AS收到相应的业务键注册和资源类型注册信息后， 反馈注 册成功的响应的给资源控制模块， 资源控制模块收到该反馈后， 确定成功 注册到 AS上。
本例中，在资源控制模块向 AS注册过程中， 当资源信息不能一次性发 送给 AS完成全部注册时， 资源控制模块可将资源信息拆分成多个包， 然后 按序发送给 AS以完成全部注册， 本例中发送每一个包时， 都必须等 AS反 馈完上一个包的注册响应后才能继续发送。 即本例中允许资源控制模块发 起多次资源信息注册， 因此本例中的资源控制模块可支持更多的业务键和 资源类型进行注册， 业务处理能力更强。
本例中的资源类型包括呼入、 呼出资源类型和媒体操作资源类型， 其 中媒体操作具体可包括 TTS ( Text To Speech, 文本语音）、 Fax (传真）、 ASR ( Automatic Speech Recognition, 自动语音识别）等媒体操作。
本例中，当 AS根据上述资源信息判断需要向资源控制模块对当前接收 到的操作请求进行鉴权处理时， AS将当前操作流程挂起， 并向资源控制模 块发送资源鉴权请求， 然后根据资源控制模块反馈的鉴权结果对当前操作 流程进行相应的处理， 本例中 AS发送的资源鉴权请求可携带有主叫号码、 被叫号码、 业务键、 资源类型和接入码。 资源控制模块接收到该资源鉴权 请求后，根据该资源鉴权请求进行鉴权处理，并将鉴权处理结果反馈给 AS, 具体的， 资源控制模块收到资源鉴权请求后， 根据业务键确定需要进行资 源鉴权的第三方业务， 再根据资源类型确定该业务占用的此类资源数量是 否超出配置限额， 若超出则返回鉴权失败， 若成功则返回鉴权成功。
本例中鉴权请求中的主叫号码、 被叫号码和接入码用于在资源控制模 块收到资源释放请求时确定业务所占用的资源并将其释放。 在鉴权成功时 分配与操作请求相对应的资源给 AS, AS收到资源控制模块反馈的鉴权成 功的鉴权结果后， 恢复当前挂起的操作流程， 继续执行后续的流程； 否贝' J , AS接收到的鉴权结果为鉴权失败， AS停止当前操作流程， 并根据资源类 型拒绝呼叫或上报业务操作失败的信息。
本例中， 若 AS向资源控制模块发送了资源鉴权请求后，在预设的时间 内未收到鉴权结果时， 则判断为鉴权失败， 停止当前的操作流程， 并根据 资源类型拒绝呼叫或上报业务操作失败的信息。 采用这种机制， 可更灵活、 有效的控制相应的资源。
本例中， 资源控制模块在向 AS注册成功后， 还可根据实际情况主动 的向 AS查询相应的资源， 请参见图 2, 具体如下： 资源控制模块向 AS发 送包含资源标识的资源查询请求， AS根据接收到的资源查询请求内包含 的资源标识进行相应资源的查询。 本例中的资源标识为一串由资源控制模 块产生的数字序列， 用来唯一标识 AS向资源控制模块申请成功的资源，且 一个资源标识所确定的资源必定属于某一种已注册的资源类型。 AS每次资 源申请成功后， 将已申请的资源信息， 包括资源类型， 主、 被叫号码， 接 入码、 业务键保存以资源标识的形式存储在哈希表中。 每次操作流程结束 释放资源时， 就从哈希表中删除相应资源标识。 因此， 当 AS收到资源查询 请求时， 根据该请求中包含的资源标识在哈希表中查找， 若找到对应的资 源标识， 则认为查询的资源被占用， 向资源控制模块回复该资源正在使用 中； 否则回复未使用。 本例中通过上述主动查询流程可有效的防止某一资 源由于 AS未正常运行而长时间被占用未释放， 从而导致资源浪费。
本例中资源控制模块向 AS注册成功后，按预设的规则持续的向 AS重 复的发送心跳检测消息以检测双方的工作状态是否正常。 在心跳检测成功， 且经判断需要向资源控制模块进行资源鉴权处理时， AS才向资源控制模块 发起资源鉴权请求。 若心跳检测失败， AS在后续接收到操作请求时， 就不 向资源控制模块进行资源鉴权处理了， 而是直接执行当前请求的流程。 在 心跳检测失败时， 资源控制模块还可向该 AS 重发资源信息以进行重新注 册， 直至注册成功。 例如：
当 AS在预设的时间段内一直未收到心跳检测消息时，则认为此时资源 控制模块发生故障，认为心跳检测失败， 因此 AS不再向资源控制模块发起 资源鉴权请求， 此时接收到的所有请求的操作流程不会再被挂起， 直到当 AS在后续过程中又重新接收到心跳检测消息， 才重新打开资源鉴权功能， 按上述方法继续进行相应资源的鉴权流程。 又例如： 当资源控制模块连续 超过预设的 N次发送心跳检测消息后都未收到 AS的响应，则判断该 AS异 常， 也认为心跳检测失败， 此时资源控制模块向该 AS重发资源信息重新进 行注册直至注册成功。
本例还提供了一种用于宽带网络的资源控制系统，请参见图 3 , 包括如 上所述的资源控制模块和 AS, 资源控制模块和 AS相互连接， 本例中二者 只要保持通信连接即可；

其中， 所述资源控制模块， 还用于为在向应用服务器注册成功之后， 向应用服务器发起心跳检测流程， 并在心跳检测成功时， 接收所述应用服 务器发起的资源鉴权请求； 在心跳检测失败时， 向该应用服务器重新发送 所述资源信息进行注册， 直至注册成功；
相应的， 所述应用服务器， 还用于为判断心跳检测是否成功， 确定心 跳检测成功时， 向资源控制模块发起资源鉴权请求； 并在心跳检测失败时， 接收资源控制模块重新发送所述资源信息， 完成注册流程。 其中， 所述应用服务器， 还用于向所述资源控制模块发送资源鉴权请 求时， 将当前请求的操作流程挂起；
收到所述资源控制模块反馈的鉴权成功的结果时， 恢复当前操作流程； 否则， 停止当前操作流程。
本例中的系统还包括与 AS连接的业务模块和媒体服务器 MS, 以及与 AS连接的用户终端 A和用户终端 B。 本例中的用户终端呼入到 AS、 AS呼 出到用户 B以及 AS向 MS发出媒体操作请求时， AS均需向资源控制模块 发送资源鉴权申请。 下面分别以呼入、 呼出操作请求和媒体操作请求为例 对本发明做进一步说明。
请参见图 4, 该图为 AS对呼入、 呼出资源进行资源控制的流程图， 在 经图 1所示的过程之后， 资源控制模块成功的注册到 AS上之后，还包括以 下步驟：
AS收到用户终端 A发起的呼入操作请求 , AS收到该请求后向用户终 端 A反馈收到该请求的响应；
AS根据资源控制模块注册的业务键和资源类型判断出该呼入操作请 求需向资源控制模块进行资源鉴权处理， AS将该呼入操作流程挂起， 向资 源控制模块发送资源鉴权请求， 该请求中包括接入码， 主、 被叫号码， 业 务键和资源类型等信息；
资源控制模块根据接收到的资源鉴权请求进行资源鉴权处理， 并将鉴 权成功的结果反馈给 AS , 同时分配相应的呼入资源给 AS;
AS收到鉴权成功的结果后， 恢复该呼入操作流程；
业务模块下发外呼用户终端 B的操作请求给 AS, AS根据资源控制模 块注册的业务键和资源类型判断出当前请求的呼出操作需由资源控制模块 对其进行资源鉴权处理， AS将该呼出流程挂起， 向资源控制模块发送资源 鉴权请求， 该请求中同样包括接入码、 主、 被叫号码、 业务键和资源类型 等信息；
业务控制模块将鉴权成功的结果反馈给 AS , 并分配相应的呼出资源给 AS, AS收到后恢复该呼出操作流程， 向被叫方即用户终端 B发送呼叫请 求连接， 用户终端 B接收到该请求后， 反馈一个响应给 AS, 并在用户摘机 后， 反馈给 AS已经接受了该通话请求的消息， AS将该消息反馈给用户终 端 A, 用户终端 A和用户终端 B开始通话；
当通话结束时， 用户终端 A向 AS发送释放资源请求， AS反馈一个响 应给用户终端 A, 并向资源管理模块发送资源释放请求， 释放申请的呼入 资源；
同时， AS通知用户终端 B通话结束， 用户终端 B反馈一个响应， 并反 馈释放资源请求给 AS, AS向资源管理模块发送资源释放请求， 释放申请 的呼出资源。
请参见图 5, 该图为 AS对媒体操作资源进行资源控制的流程图， MS 可以是 SIP或 MGCP, 本例以 SIP的 MS为例做进行一步说明， 在经图 1 所示的过程之后，资源控制模块成功的注册到 AS上之后，还包括以下步驟： 在用户终端 A呼入后， 业务模块给用户终端 A放音， 向 AS下发媒体 操作请求；
AS 根据资源控制模块注册的业务键和资源类型判断出当前的媒体操 作请求需由资源控制模块对其进行资源鉴权处理， AS将该媒体操作流程挂 起， 向资源控制模块发送资源鉴权请求；
资源处理模块接收到该资源鉴权请求后， 对其进行鉴权处理， 并将鉴 权处理结果反馈给 AS, 同时分配相应的媒体操作资源给 AS;
AS收到鉴权成功的结果后， 恢复该媒体操作流程， 通知媒体服务器给 用户终端 A放音；
媒体操作结束时， AS向资源控制模块发送释放资源请求， 请求释放已 申请的媒体操作资源。
综上可知， 本发明通过增加资源控制模块， 使资源控制模块通过向 AS 注册完成与 AS资源信息交互， AS收到操作请求后，可根据上述资源信息 判断是否需要向资源控制模块请求进行资源鉴权， 并根据资源控制模块鉴 权处理的结果对当前请求的操作流程进行相应的处理， 并在当前的操作流 程结束时， AS还向资源控制模块发送资源释放请求， 请求释放已申请的与 所述操作请求所对应的资源。因此本发明提供的资源控制模块可与 AS有机 的结合完成相应资源的鉴权，从而使 AS在 SaaS和 PaaS模型下能够基于租 户来进行资源控制，提高 AS的通用性的同时，也提高了资源管理的集中性， 降低了资源管理的复杂度和成本。 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的 普通技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干简单 推演或替换， 都应当视为属于本发明的保护范围。
