图 2为本发明实施例的应用服务器的一结构示意图；
图 3为本发明实施例的应用服务器的另一结构示意图；
图 4为本发明实施例的媒体资源分配方法的流程示意图；
图 5为本发明实施例的媒体资源分配方法的另一流程示意图。 具体实施方式 本发明实施例基于 NGN或 IMS网络系统，下面筒单介绍 NGN/IMS的 网络系统结构图。如图 1所示为本发明实施例的 NGN/IMS网络系统的结构 示意图， NGN/IMS 网络系统主要包括以下网元： 用户终端 （UE, User Equipment ), NGN/IMS网络、 应用服务器和媒体服务器。 在用户终端发起 呼叫时， 通过 NGN/IMS网络将该呼叫触发至应用服务器上，应用服务器控 制媒体服务器为该呼叫分配媒体资源。
下面结合附图和实施例， 对本发明的具体实施方式作进一步详细描述。 如图 2所示为本发明实施例的应用服务器的一结构示意图， 该应用服 务器包括：
触发模块 101 , 用于在接收到用户终端的呼叫时， 触发该呼叫对应的业 务应用。 本发明实施例中， 用户终端可以通过有线或无线的方式接入 NGN/IMS网络， 在用户终端发起呼叫时， 通过 NGN/IMS网络， 使用会话 初始化协议（SIP, Session Initiation Protocol ) 消息触发应用服务器上的相 应的业务应用， 该业务应用可以为企业客服热线等。
分析模块 102, 用于分析该呼叫需要占用的媒体资源个数。 该媒体资源 个数可以包括： 端口数、 放音、 收号、 录音、 传真和会议等。
获取模块 103 ,用于获取该业务应用中媒体资源的占用上限以及当前占 用个数。
判断模块 104, 用于根据该呼叫需要占用的媒体资源个数、该业务应用 中媒体资源的占用上限以及当前占用个数， 判断是否满足媒体资源分配条 件。
处理模块 105, 用于在满足媒体资源分配条件时，控制媒体服务器为该 呼叫提供媒体资源， 否则结束该呼叫。 结束呼叫的具体体现形式可以是直 接结束呼叫， 也可以是播放提示音后结束呼叫等， 具体的可以按照各个业 务应用的业务逻辑自行定义。
另外， 在分配媒体资源之前， 还需要根据用户的需求， 为每一业务应 用需要使用的媒体资源配置一占用上限， 如图 3所示为本发明实施例的应 用服务器的另一结构示意图， 在图 2所示的实施例的基础上， 该应用服务 器还包括： 配置模块 106, 连接获取模块 103 , 用于为能够支持的每一业务 应用需要使用的媒体资源配置一占用上限。 例如， 在一个企业客服热线的 业务应用中， 可以配置该业务应用对端口资源、 放音资源或会议资源等多 种媒体资源的占用上限。 另外， 在用户的需求发生变化时， 可以根据用户 的需求， 对配置的媒体资源上限进行更新。
以某企业客服热线的业务应用为例， 对上述实施例中的应用服务器进 行详细说明。
殳设该企业用户购买了 200个放音资源、 200个录音资源、 50个会议 资源， 该应用服务器为该企业客服热线的业务应用配置的媒体资源的占用 上限分别为： 放音资源的占用上限为 200, 录音资源的占用上限为 200, 会 议资源的占用上限为 50, 即对业务应用中的所有媒体资源分类进行限制。
假设当前有一用户呼叫呼入， 应用服务器分析出该呼叫的目的号码为 该企业的客服热线， 触发模块 101 则触发该企业客服热线的业务应用， 分 析模块 102 分析出该用户呼叫需要占用的媒体资源为： 一个放音资源和一 个录音资源， 另外， 获取模块 103获取到该业务应用的放音资源占用上限 为 200, 录音资源占用上限为 200, 该企业应用中当前占用的放音资源的个 数为 60, 录音资源为 55 , 此时， 由于放音资源和录音资源足够， 因此， 判 断模块 104判断出当前仍满足媒体资源分配条件， 处理模块 105控制媒体 服务器为呼叫提供放音资源和录音资源。 如果获取模块 103获取到该企业 应用中当前占用的放音资源的个数为 200, 录音资源为 110, 此时， 由于放 音资源不足， 因此， 判断模块 104判断出当前不满足媒体资源分配条件， 处理模块 105则结束该呼叫。
上述实施例中， 判断模块 104在判断当前是否满足媒体资源分配条件 时， 可以将用户呼叫需要占用的媒体资源个数， 与呼叫对应的业务应用中 媒体资源的当前占用个数求和， 并将求得的和值与业务应用中媒体资源的 占用上限进行比较， 判断该和值是否超过业务应用中媒体资源的占用上限， 从而判断出是否满足媒体资源分配条件。
如图 3所示， 判断模块 104包括：
求和单元 1041 , 用于对呼叫需要占用的媒体资源个数与业务应用中媒 体资源的当前占用个数求和， 得到一和值；
比较单元 1042, 用于判断和值是否超过业务应用中媒体资源的占用上 限， 如果是， 判定满足媒体资源分配条件， 否则， 判定不满足媒体资源分 配条件。
另外， 在用户呼叫结束时， 应用服务器还需要释放呼叫占用的媒体资 源， 因此， 如图 3所示， 该应用服务器还包括：
释放模块 107, 连接处理模块 105, 用于在结束呼叫时， 释放该呼叫占 用的媒体资源。 用户呼叫结束时， 应用服务器需要将该呼叫所占用的各种 媒体资源全部释放，具体的，应用服务器可以向媒体服务器发起结束（BYE ) 消息， 指示媒体服务器释放用户呼叫所占用的媒体资源， 其中， BYE消息 是 SIP信令的一种。
由于在释放当前呼叫占用的媒体资源后， 业务应用中媒体资源的当前 占用个数也会发生变化， 因此， 应用服务器还包括： 更新模块 108, 连接获 取模块 103和释放模块 107, 用于在释放该呼叫占用的媒体资源时， 更新该 呼叫对应的业务应用中媒体资源的当前占用个数。
通过上述实施例提供的应用服务器， 可以根据用户需求， 为每一业务 应用需要使用的媒体资源配置一占用上限， 在接收到用户终端的呼叫时， 根据该呼叫需要占用的媒体资源个数、 该呼叫对应的业务应用中媒体资源 的占用上限以及当前占用个数， 来判断是否为该呼叫分配媒体资源， 从而， 使得每个用户的业务应用都能够得到保障， 有助于运营商改善服务质量。
同时， 应用服务器可以根据为业务应用配置的媒体资源占用上限， 对 用户进行收费， 改进了运营商的收费方式， 区别与现有技术中根据用户实 际占用的媒体资源个数进行收费的方式。
另外， 通过应用服务器为多个媒体服务器分配媒体资源， 不需要对媒 体服务器的组网模式作任何改动， 实现筒单。
如图 4所示为本发明实施例的媒体资源分配方法的一流程示意图， 该 媒体资源分配方法包括以下步骤：
步骤 401 ,应用服务器在接收到用户终端的呼叫时， 触发该呼叫对应的 业务应用。 在用户终端发起呼叫时， 通过 NGN/IMS网络， 使用 SIP消息触 发应用服务器上的相应的业务应用。
步骤 402,应用服务器分析该呼叫需要占用的媒体资源个数。 该媒体资 源个数可以包括： 端口数、 放音、 收号、 录音、 传真和会议等。
步骤 403 ,应用服务器获取该业务应用中媒体资源的占用上限以及当前 占用个数。
步骤 404,应用服务器根据该呼叫需要占用的媒体资源个数、该业务应 用中媒体资源的占用上限以及当前占用个数， 判断是否满足媒体资源分配 条件， 如果是， 执行步骤 405; 否则， 执行步骤 406。
步骤 405 , 应用服务器控制媒体服务器为该呼叫提供媒体资源。
步骤 406, 应用服务器结束该呼叫。
上述实施例中， 判断模块 104在判断当前是否满足媒体资源分配条件 时， 可以将用户呼叫需要占用的媒体资源个数， 与该呼叫对应的业务应用 中媒体资源的当前占用个数求和， 并将求得的和值与该业务应用中媒体资 源的占用上限进行比较， 判断该和值是否超过该业务应用中媒体资源的占 用上限， 从而判断出是否满足媒体资源分配条件。
因此， 上述步骤 404还可以包括以下步骤：
步骤一， 应用服务器对该呼叫需要占用的媒体资源个数与该业务应用 中媒体资源的当前占用个数求和， 得到一和值；
步骤二， 应用服务器判断该和值是否超过该业务应用中媒体资源的占 用上限， 如果是， 判定满足媒体资源分配条件； 否则， 判定不满足媒体资 源分配条件。
另外， 在分配媒体资源之前， 还需要根据用户的需求， 为每一业务应 用需要使用的媒体资源配置一占用上限， 上述步骤 404之前还可以包括： 应用服务器配为能够支持的每一业务应用需要使用的媒体资源配置一占用 上限的步骤。
另外， 在用户呼叫结束时， 应用服务器还需要释放该呼叫占用的媒体 资源， 因此， 上述媒体资源分配方法还包括： 应用服务器在结束呼叫时， 释放该呼叫占用的媒体资源的步骤。
由于在释放当前呼叫占用的媒体资源后， 该业务应用中所述媒体资源 的当前占用个数也会发生变化， 因此， 应用服务器在结束该呼叫时， 释放 该呼叫占用的媒体资源的步骤之后还包括： 应用服务器更新该呼叫对应的 业务应用中媒体资源的当前占用个数的步骤。
下面以分配放音资源为例， 详细描述应用服务器分配媒体资源的方法 的处理流程， 如图 5所示， 可以具体包括如下步骤：
步骤 501 , 用户终端通过 NGN/IMS网络呼入， 使用请求（ INVITE )消 息触发应用服务器上的一业务应用， 其中， INVITE消息中携带用户终端的 媒体描述信息 （SDP, Session Description Protocol ), 该媒体描述信息用于 描述流媒体初始化参数等信息。 步骤 502,应用服务器分析当前用户呼叫需要占用的媒体资源个数， 并 获取该业务应用中媒体资源的占用上限以及当前占用个数， 依此判断是否 分配媒体资源。
假设， 当前用户呼叫需要占用的放音媒体资源为 M个， 应用服务器上 为该业务应用配置的放音媒体资源上限为 R个， 该业务应用中当前已使用 的放音媒体资源的个数为 N个， 求 M与 N之和， 如果大于 R, 则执行步骤 503, 否则， 执行步骤 504。
步骤 503, 表示当前放音媒体资源不足， 应用服务器回复错误信息给 NGN/IMS网络，并转发至用户终端，该错误信息可以由业务应用自行指定， 比如 480消息， 然后结束整个呼叫流程。
步骤 504, 表示当前放音媒体资源足够， 应用服务器发送 INVITE消息 到媒体服务器， 携带用户终端的 SDP。
步骤 505 , 媒体服务器回复 200 OK消息给应用服务器， 该 200 OK消 息中携带媒体服务器的 SDP ,应用服务器将此 200 OK消息转发至 NGN/IMS 网络， 并响应给用户终端。
步骤 506 , 得到用户终端的确认后， NGN/IMS网络发送确认（ ACK ) 消息给应用服务器， 应用服务器将该 ACK消息转发至媒体服务器。
步骤 507, 应用服务器发送 INFO ( Information ) 消息至媒体服务器， 消息中携带放音指令。
步骤 508, 媒体服务器针对该 INFO消息， 返回 200 OK消息至应用服 务器。
步骤 509, 媒体服务器执行正常的放音流程。
步骤 510,呼叫结束时， 用户终端通过 NGN/IMS网络发送结束（ BYE ) 消息给应用服务器， 应用服务器进行媒体资源的释放， 并重新计算该业务 应用中的放音媒体资源当前占用个数， 并对媒体服务器发送 BYE消息。 上述实施例中， 所述 INVITE、 480、 200 OK、 ACK、 INFO消息均为 SIP信令。
以上所述仅是本发明的优选实施方式， 应当指出， 对于本技术领域的 普通技术人员来说， 在不脱离本发明原理的前提下， 还可以作出若干改进 和润饰， 这些改进和润饰也应视为本发明的保护范围。
