The high layer signaling - radio access network application part ( ranap ) is a very important part of iu intertface in the third generation mobile communication system . it is designed and realized in this paper . we are mainly in charge of the side of radio network controller ( rnc ) 本文主要介绍了第三代移动通信系统( wcdma )中无线网络控制器( rnc )侧的iu接口的高层信令无线接入网络应用部分( ranap )协议的软件设计与实现方案。
The design and realization of ranap plays a very important role in the independent development of the third generation mobile communication system device of our china . the system utilizes finite state machine ( fsm ) as the basement of system design and realization . 无线接入网络应用部分( ranap )协议软件是第三代移动通信信令处理协议栈的重要组成部分，它的设计和实现为国家早日实现自主生产的第三代移动通信设备具有重要的意义。
Based on the studies of gprs streaming service model , radio access network communication protocol and qos related specification of 3gpp , we discussed the scheme of streaming traffic in ( e ) gprs radio access network , including mainly qos management module such as access control , flow control and scheduling 通过对3gpp中gprs流业务服务模型、无线子网络的通信协议以及qos相关规范的研究,讨论了具体流式数据业务传输在( e ) gprs无线接入网络中实现方案,包括接入控制、调度控制和流量控制等主要qos管理控制功能模块。
Due to the heterogeneous future wireless mobile networks , this will demand pervasive ip mobility support when a mobile host roams around . however , the current tcp / ip protocol suite is not able to fully support ip mobility , especially where real - time applications are concerned 越来越多的移动设备和用户希望能够随时随地进行互联网无缝接入，而未来的无线接入网络是由多种异质网络构成的复杂多层次的立体结构，这要求网络支持ip移动性，即网络具有ip移动计算功能。
