在电信网络丰富的异构特征下,终端是网络互通和融合的关键节点。在异构环境中,终端的四个基本组成部分——移动终端、终端设备、UICC和对外接口需要按照不同的方法进行增强。对于移动终端,通过可编程、可配置、模块化的处理方式,在不增加体积、功耗和成本的前提下,实现对多种甚至是任意无线接入技术的感知和选择;对于终端设备,使用对外接口聚合外围的输入输出设备,使用户的获得更加丰富和优质的业务体验;对于UICC需要增加容量;对于对外接口,需要扩展带宽和稳定性。 Under the heterogeneous characteristics of telecommunication networks, terminals are the key nodes in network interworking and convergence. In a heterogeneous environment, the four basic components of a terminal - the mobile terminal, the terminal equipment, the UICC, and the external interface need to be enhanced in different ways. For the mobile terminal, sensing and selection of multiple or even arbitrary wireless access technologies can be realized without increasing the size, power consumption and cost through a programmable, configurable, and modular processing manner; for a terminal device, The use of external interface aggregation peripheral input and output devices to enable users to get more rich and high-quality business experience; For UICC need to increase capacity; For the external interface, you need to expand the bandwidth and stability.
