为使本发明的目的、 技术方案和优点更加清楚， 下面将结合附图对本发明实施方式作 进一步地详细描述。
实施例 1
如图 1所示， 本实施例 1提供了一种预约会议的方法， 该方法包括如下步骤：
101、接收会议发起者发送的预约会议的请求消息，请求消息携带预约会议的会议参数; 其中， 上述会议参数中包括预约会议的与会终端的标识信息和预约会议的召开时间段， 会议发起者具体可以为与会终端或视频会议的处理设备中的会议发起模块；
102、 根据预约会议的与会终端的标识信息确定与会终端需求的网络带宽；
103、 当预约会议的召开时间段的可用网络带宽满足与会终端需求的网络带宽时， 为与 会终端预留网络带宽。
本发明还可以进一步包括向会议发起者发送预约会议成功的响应消息。
所述预约会议的召开时间段的可用网络带宽具体通过以下步骤获得：
获取所述与会终端所属的汇聚点接入会议的最大允许带宽；
将所述汇聚点接入会议的最大允许带宽减去所述预约会议的召开时间段已经预约的网 络带宽， 即为所述预约会议的召开时间段的可用网络带宽。
本实施例的执行主体可以包括但不限于实施例 2和 3的会议系统或者预约会议的系统。 在执行步骤 101 之前， 所述方法还可以包括： 在所述会议系统或者预约会议的系统上配置 所述与会终端需求的网络带宽和所述与会终端所属的汇聚点接入会议的最大允许带宽。
本实施例的方法还可以包括：

如图 2所提供的架构， 会议系统至少包含一个会议应用服务器和会议媒体资源服务器, 会议应用服务器提供会议资源管理以及会场控制功能， 比如预约会议、 撤销会议、 邀请与 会者等； 会议媒体资源服务器提供多方会议端口资源。 会议系统可以部署在运营商网络， 也可以部署在企业专网。
用户通过与会终端 （例如多媒体会议室及会议室中配置的用于进行视频会议的终端、 用于视频会议管理的会议系统） 进行视频会议， 为通信交换网络的一部分， 通信交换网络 可以是 IMS( IP Multimedia Subsystem， IP多媒体子系统）、软交换或 IP PBX(Private Branch exchange, 小交换机）， 提供呼叫处理和路由功能； 会议系统与通信交换网络连接， 提供会 议业务。 其中， 用户也可以是会议系统的一部分， 且此时由会议系统提供呼叫处理和路由 功能。
与会终端通过汇聚点接入会议应用服务器， 其中， 汇聚点为运营商或组网者为用户提 供的用于接入 IP 网的节点 （通常为路由设备）， 并由运营商或组网者为用户设定最大允许 带宽。 以表 1所示为例进行说明。
比如， 当前 IP网络中共存在两个汇聚点： 路由设备 1和路由设备 2;
在会议系统部署前， 本方法首先包括：
在路由设备 1/路由设备 2中配置 Diffserv (Differentiated Services , 区分服务） 的 QoS ( Qual ity of Service, 服务质量） 策略， 控制用户接入会议媒体资源服务器的最大 允许带宽；
其中， 对配置用户接入会议媒体资源服务器的最大允许带宽进行具体说明如下： 路由设备 1为公司甲向运营商申请得到， 其最大允许带宽共为 14M (例如， 以付费的形 式获得）， 且管理员将公司甲中业务流类型划分为三种并进行每种业务流的最大允许带宽的 分酉己： VoIP (Voice over Internet Protocol ,数字化模拟声讯信号）业务为 2M, Telepresence Conference (远程会议， 即多媒体会议） 业务为 10M， Internet (因特网） 业务为 2M; 路由设备 2为公司乙向运营商申请得到， 其最大允许带宽共为 12M (例如， 以付费的形 式获得）， 且管理员将公司乙中业务流类型划分为三种并进行每种业务流的最大允许带宽的 分配： VoIP业务为 2M Telepresence Conference业务为 8M Internet业务为 2M 会议应用服务器配置:

会议媒体资源服务器汇聚点路由设备 QoS配置:
Figure imgf000007_0002
表 1
在完成对用户接入会议媒体资源服务器的最大允许带宽的配置后， 本方法还包括： 根据用户接入会议媒体资源服务器的最大允许带宽， 配置与会终端接入会议的需求的 网络带宽和与会终端所属的汇聚点接入会议的最大允许带宽， 以便于在预定会议、 会议接 入控制时会议应用服务器把网络带宽资源作为会议资源之一进行统一管理。
其中， 与会终端所属的汇聚点接入会议的最大允许带宽， 即为会议系统设置的可为用 户提供的进行多媒体会议的最大允许带宽。
需要说明的是， 由于用户的汇聚点对于带宽的限制， 会议系统为用户提供超过用户接 入会议媒体资源服务器的最大允许带宽的带宽资源是无意义的， 因此， 一般的将用户接入 会议媒体资源服务器的最大允许带宽设置为与会终端所属的汇聚点接入会议的最大允许带 宽。
如表 1所示， 将路由设备 1接入会议的最大允许带宽设置为 10M， 将路由设备 2接入会 议的最大允许带宽设置为 8M
具体地， 对于配置与会终端接入会议时需求的网络带宽， 主要根据与会终端所属的汇 聚点接入会议的最大允许带宽和与会终端对于会议的质量要求进行确定， 将与会终端所属 的汇聚点接入会议的最大允许带宽分别分配给该汇聚点内的各个与会终端。
如表 1所示， 在本实施例中， 设定甲公司共有 3个多媒体会议室， 分别对应于与会终 端 Al、 A2、 A3, 每个会议室对于视频会议的质量要求不同， 为与会终端 Al、 A2、 A3分别设 定需求的网络带宽为 2M、 4M、 6M。
设定乙公司共有 3个多媒体会议室， 分别对应于与会终端 Bl、 B2、 B3， 每个会议室对 于视频会议的质量要求不同； 为与会终端 Bl、 B2、 B3分别设定需求的网络带宽为 2M、 2M、 氛
需要说明的是， 会议应用服务器在地址本中记录了与会终端的相关信息， 比如与会终 端的电话号码、 音视频能力、 物理位置等。 其中， PHB (Per-Hop Behavior, 逐跳行为） 为 Diffserv的 QoS策略的一种，可包括： DF (Default Forwarding,默认转发）、 EF (Expedited Forwarding, 迅速转发)、 AF (Assured Forwarding, 石角保转发)。
如图 3所示， 一种预约会议的方法， 具体包括如下步骤：
201、 接收会议发起者发送的预约会议的请求消息；
其中， 上述请求消息中携带有预约会议的会议参数， 该会议参数至少包括预约会议的 召开时间段和预约会议的与会终端的标识信息；
需要说明的是， 上述预约会议的召开时间段可以为预约会议的开始时间和结束时间， 也可以为预约会议的开始时间和时长， 只要能够确定预约会议的召开时间段即可。
进一步地， 会议参数还可以包括： 与会者数、 与会者身份的信息等。
在本实施例中， 与会者指参加会议的人选， 多个与会者可通过同一个与会终端接入视 频会议， 与会者身份的信息具体为标识与会者身份的信息， 例如与会者的姓名、 邮箱、 手 机号码等， 且与会者可通过会议系统提供的地址本进行选择。
进一步地， 在用户预约会议时， 会议系统还可以向会议发起者提供设置会议号及会议 密码的功能， 以便在与会终端接入会议时进行身份认证。
202、 根据会议参数确定预约会议所需的端口资源需求；
203、 判断预约会议的召开时间段内的可用端口资源是否满足预约会议所需的端口资 源， 如果不满足， 执行步骤 204， 如果满足， 执行步骤 205;
204、 提示端口资源不足， 预约会议失败， 结束操作；
进一步地， 在提示端口资源不足时， 还可以包括：
向用户提供会议预约建议， 例如在其它时间段进行预约。
205、 根据预约会议所需的端口资源需求在预约会议的召开时间段内的可用端口资源中 为预约会议预留端口资源， 执行步骤 206 ;
206、 根据预约会议的与会终端的标识信息确定与会终端需求的网络带宽；
例如， 如表 1所示， 当与会终端 A1预约会议时， 则需求的网络带宽为 2M， 当与会终端 A2预约会议时， 则需求的网络带宽为 4M。
207、 判断在预约会议的召开时间段的可用网络带宽是否满足与会终端需求的网络带 宽， 如果满足， 执行步骤 208， 如果不满足， 执行步骤 209 ;
在本实施例中， 在判断在预约会议的召开时间段的可用网络带宽是否满足与会终端需 求的网络带宽之前， 本方法还可以包括：
获取预约会议的召开时间段的可用网络带宽；
进一步地， 对上述获取预约会议的召开时间段的可用网络带宽进行具体说明： 获取预约会议的与会终端所属的汇聚点接入会议的最大允许带宽；
将上述汇聚点接入会议的最大允许带宽减去预约会议的召开时间段已经预约的网络带 宽， 即为预约会议的召开时间段的可用网络带宽。
例如： 当与会终端 A1发起预约会议时， 获取会议应用服务器为 A1所属的汇聚点 （即 路由设备 1 ) 配置的可接入会议应用服务器的最大允许带宽为 10M， 而此时， 由于用户 A2 已经在该时间段预约了会议， 会议应用管理器为 A2预约的会议预留了 4M网络带宽资源， 因此， 可得到预约会议的召开时间段的可用网络带宽为 10M-4M=6M。 相应地， 由于与会终端 A1配置的对于预约会议需求的网络带宽为 2M， 显然可用网络带宽大于 A1需求的网络带宽， 则可为 A1预约会议。
又例如： 当与会终端 A1发起预约会议时， 获取会议应用服务器为 A1所属的汇聚点（即 路由设备 1 ) 配置的可接入会议应用服务器的最大允许带宽为 10M， 而此时， 由于用户 A2 和 A3均已经在该时间段预约了会议，会议应用管理器为 A2和 A3预约的会议分别预留了 4M 和 6M 的网络带宽资源， 因此， 可得到预约会议的召开时间段的可用网络带宽为 10M-4M-6M=0M。 相应地， 由于与会终端 A1配置的对于预约会议需求的网络带宽为 2M， 显然 无可用网络带宽， 不可为 A1预约会议。
其中， 需要说明的是， 与会终端对于预约会议需求的网络带宽均为预先配置好（如表 1 所示）， 因此， 在确定预约会议的与会终端后， 即可根据与会终端的标识信息在会议应用服 务器中查找得到其对应需求的网络带宽， 例如， 与会终端 A1需求的网络带宽为 2M， 与会终 端 B1需求的网络带宽为 2M。
208、 根据与会终端需求的网络带宽在预约会议的召开时间段内的可用网络带宽中为预 约会议预留网络带宽资源， 预约会议成功， 结束操作； 需要说明的是， 在预约会议的召开时间段内的可用网络带宽中为预约会议预留网络带 宽后， 则在该预约会议被撤销前， 该被预留的网络带宽在会议的召开时间段内即不可被其 他用户预定使用。
进一步地， 在预约会议成功之后， 本方法还包括：
会议系统为该预约成功的会议分配会议号和会议密码， 以便在与会终端接入会议时进 行认证。
209、 提示网络带宽资源不足， 预约会议失败， 结束操作。
进一步地， 在提示网络带宽资源不足时， 还可以包括：
向用户提供会议预约建议， 例如在其它时间段进行预约。
进一步地， 会议系统还可以提供对预约成功的会议进行撤销和查询可用网络带宽资源 的功能；
例如， 在会议成功预约后， 本方法还可以包括：
接收用户发出的撤销预约会议的请求， 并撤销预约会议的预约。
在任意时刻， 本方法还可以包括：
接收用户发出的查询预设时间段内可用网络带宽的请求， 并通知该用户在预设时间段 内的可用网络带宽。
更进一步地， 会议系统在对会议成功预约后， 还可以提供扩展参加预约会议的与会终 端的功能；
具体地， 当到达预约会议的开始时间后， 方法还包括：
接收未预约的与会终端发起的参加预约会议的请求消息；
判断当前是否有可用的网络带宽；
当确认当前有可用的网络带宽时， 准许所述未预约的与会终端接入预约会议； 当确认当前没有可用的网络带宽时， 拒绝该未预约的与会终端接入预约会议。
其中， 会也可以根据不同会议属性来决定在预留带宽资源不足时是否允许用户加入会 议， 如果允许则会议应用服务器需要规划一定比例的公共带宽资源 （即未被预留的网络带 宽资源） 来接纳这部分用户， 当可用的公共带宽资源都不足时用户呼叫请求将被拒绝。
以表 1所示的配置对本实施例所提供的方法的效果进行说明：
例如， 当与会终端 Al、 A2、 A3预约在同一时间段进行高清 /智真会议， 在使用传统技 术的情况下， 路由设备 1规划的高清 /智真会议业务带宽无法满足用户 Al、 A2、 A3在同一 时段参加会议 （可以是同一个会议， 也可以是不同会议） 的需求的网络带宽， 会议质量无 法保证， 而使用本发明的技术在进行会议预约时， 会避免与会终端 Al、 A2、 A3同时进行会 议， 则可保证用户会议的顺利进行。
另外， 如图 4所示， 本发明实施例还提供了另一种会议系统的架构， 通过外置策略控 制器来进行网络带宽资源管理， 策略控制器支持预留将来某个时间的网络资源， 并提供资 源查询、 预留、 使用、 释放接口给会议应用服务器调用， 其所完成的功能及方法如上所述， 这里不再赘述。 本实施例提供了一种预约会议的方法和系统， 通过根据预约会议的与会终端的标识信 息确定与会终端需求的网络带宽， 当所述预约会议的召开时间段的可用网络带宽满足所述 与会终端需求的网络带宽时， 为所述与会终端预留网络带宽， 以保证预约成功的会议的与 会终端具有足够的带宽资源， 保证会议召开时的会议质量， 给用户以良好的用户体验。 实施例 3
如图 5所示， 本实施例提供了一种预约会议的系统， 该系统包括：
接收模块 301， 用于接收会议发起者发送的预约会议的请求消息， 请求消息携带预约会 议的会议参数， 会议参数包括预约会议的与会终端的标识信息和预约会议的召开时间段； 确定模块 302，用于根据预约会议的与会终端的标识信息确定与会终端需求的网络带宽； 预约模块 303， 用于当预约会议的召开时间段的可用网络带宽满足与会终端需求的网络 带宽时， 为与会终端预留网络带宽。
可选地， 所述预约模块 303还可以用于向会议发起者发送预约会议成功的响应消息。 进一步地， 如图 6所示， 上述系统还包括：
获取模块 304， 用于获取预约会议的召开时间段的可用网络带宽；
如图 7所示， 获取模块 304， 具体包括：
最大带宽获取单元 3041，用于获取与会终端所归属的汇聚点接入会议的最大允许带宽； 可用带宽获取单元 3042， 用于将汇聚点接入会议的最大允许带宽减去预约会议的召开 时间段已经预约的网络带宽， 即为预约会议的召开时间段的可用网络带宽。
进一步地， 如图 8所示， 上述系统还包括：
配置模块 305，用于配置与会终端需求的网络带宽和与会终端所属的汇聚点接入会议的 最大允许带宽。
进一步地， 如图 9所示， 所述接收模块 301， 还用于接收未预约的与会终端发起的参加 预约会议的请求消息；
