摘　　要：泛在网将个人通信、娱乐、业务应用等都融合在了一张网内,给用户带来了更丰富的业务体验。而移动化的泛在网将更加强调用户即使在移动的状态下,也能够无缝地获得无所不能、无所不包的服务,而移动性预测技术作为一种主动积极的基于位置的服务,同时面临了更多的挑战。在研究现有移动性预测的基础上,针对未来移动泛在网络的业务模式及需求,分析了在移动泛在网络环境下的移动预测应具备的特点及其研究方向。为了能够充分适用于移动泛在网络,提出了未来的移动性预测技术,需要解决网络异构性、终端协同性以及业务智能性对移动性预测技术带来的挑战。Ubiquitous network combines individual communication, entertainment and application services into a single network. Thereby, users can enjoy more various business experiences. The mobile ubiquitous network emphasizes that users are able to acquire various application services continuously when they are moving. Therefore, higher request of mobility prediction technology was put forward. Current mobility prediction technology was researched and the features of mobility prediction technology which belong to mobile ubiquitous network according to applications in future mobile ubiquitous network were analyzed. In order to be adapted by mobile ubiquitous network sufficiently, the prediction of mobility presented need to solve the challenges brought by heterogeneity, terminal collaboration and intelligent application.
