SPDF102通过 Gq,接口接收 AF101的分配资源请求,根据预先设置 的策略对该请求进行处理,并根据处理结果通过 la接口向 BGF103发送 进一步的资源请求, 将 BGF103发送的资源请求的结果返回给 AF101;
BGF103是一个分组到分组的网关, 用于根据 SPDF102的资源请求 执行策略并进行必要的网络地址转换功能, 并将资源请求的结果发送给 SPDF102。

步骤 201 : AF向 SPDF发起 VOD业务申请。
步骤 202: SPDF进行授权策略控制。
步骤 203: SPDF向 BGF下发 VOD业务所需的策略。
步骤 204: BGF向 SPDF发送 VOD业务所需的策略应答。
步骤 205: SPDF通知 AF VOD业务授权成功。
此时, 开始正常播放 VOD业务, 假设此时, AF发起新的业务如电话 业务, 那么执行步骤 206-步骤 212。
步骤 206: AF向 SPDF发起新的电话业务申请。
步骤 207: SPDF根据 QoS策略抢占正在提供的 VOD业务资源。
步骤 208: SPDF向 BGF下发释放 VOD业务资源策略。
步骤 209: BGF向 SPDF发送释放 VOD业务资源应答。

可以看出, 采用目前实现新业务加入的方法, 会造成新业务抢占正 在进行的业务的资源, 也就是当前业务的资源, 使得正在进行的业务因 所需资源的不足而被迫终止, 即被新业务抢占, 而被抢占的业务必须在 新业务结束后重新提出申请, 并且网络从头提供该项服务, 从而给用户 带来了不便。 发明内容
