IP移动技术是专门用于在用户从一个网络移动到另一个网络时,为用户提供网络访问的软件和硬件。Cisco把它叫做“无所不在的连接”。移动电话网络已经做到了这一点:你可以在加利福尼亚拨打移动电话,然后一路驾车到纽约,而电话不会掉线,前提是在高速公路旁一直都有移动电话发射塔 IP Mobile Technology is software and hardware specifically designed to provide users with network access as they move from one network to another. Cisco calls it “ubiquitous connectivity.” The mobile phone network has done this: you can make a mobile phone call in California, and then drive all the way to New York, and the phone will not drop, provided there is always a mobile phone tower near the highway
