一种移动终端实现可视电话三方通话的方法及*** 技术领域
本发明涉及智能移动终端可视电话技术, 尤其涉及一种移动终端实现 可视电话三方通话的方法及***。 背景技术
随着移动通信技术的发展, 在移动终端如手机中实现可视电话, 成为 第三代 (3G, 3rd-generation )移动通信技术的智能手机区别于各种低端 手机的一个特色服务内容。 通过可视电话, 可以实现人们面对面的实时沟 通, 即: 通话双方在通话过程中能够互相看到对方场景。 近些年来, 可视 电话已广泛应用于远程会议、 远程教学以及远程医疗等多方面, 可视电话 包括双方通话、 三方通话等, 其中三方通话又称为会议电话, 可以在不中 断已有双方通话的情况下, 接入第三方通话, 进而实现多方的相互通话。
但是,在目前移动终端的可视电话应用中,由于受 3G网络带宽的限制, 还不能够实现三方通话。 具体的讲, 3G网络的带宽分配机制与无线路由器 非常类似, 其理论速度可达下行 3 ~ 4Mbit/s, 上行可达 2Mbit/s左右, 而在 实际应用中, 基站除了要分配一定的信道给无线上网用户使用外, 还要分 配一定的信道给语音通信用户使用, 也就是说, 3G网络的信道资源并不是 独享给每位用户的, 而是让多位用户共享使用的。 因此, 在实际应用中, 3G网络的接入速度不仅取决于基站的信号强度, 还要取决于当前基站的通 信量, 如果基站非常闲, 则接入速度将会非常快, 相反, 接入速度就会非 常緩慢。
这种情况下, 如果要在移动终端的可视电话应用中实现三方通话, 将 会大大增加网络带宽的消耗, 甚至当网络带宽小于某个值之后, 三方通话 将无法建立, 从而大大影响用户体验。 所以, 如何使用有限的带宽在移动 终端的可视电话应用中实现三方通话,成为 3G智能手机研发的一个重要技 术内容。 发明内容
