Description

卫星网络通信方法、代理服务装置及网关
本申请要求在2017年11月30日提交中国专利局、申请号为201711240121.3的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及卫星通讯技术领域，例如涉及一种卫星网络通信方法、代理服务装置及网关。
背景技术
蜂窝式移动通讯系统的信号不能覆盖在海上以及陆地的部分区域，卫星通讯作为一种有效的补充手段，广泛应用于这些区域，尤其是远洋运输、钻探、勘测以及渔业等部门。卫星通讯具有不受时间、地点、环境等多种因素的限制，开通时间短、传输距离远、网络部署快、通信成本与通信距离无关等诸多优点，可以实现语音和数据的实时双向传输。
如图1所示，相关卫星通讯应用场景中，用户设备(User Equipment，UE)通过网关(Gateway，GW)1接入卫星网络后，如果UE通过空口访问公网资源，要先通过传输控制协议(Transmission Control Protocol，TCP)协议三次握手建立到公网资源的TCP通道，再通过超文本传输协议(HyperText Transfer Protocol，HTTP)进行对应的资源传输。典型的卫星通信具有大延时(比如，540ms左右)和网络不稳定的特点，这会造成TCP协议不停的重传，引起通信链路的拥塞，浪费卫星带宽，影响用户上网体验。由于卫星带宽昂贵，这种额外的带宽浪费可能会导致用户上网面临高昂的网费。
