In chapter 4, the mobile multimedia mail system based on CDMA radio network is introduced and compared with Multimedia Messaging Service of China Mobile. 第四章介绍了基于CDMA无线网络的移动多媒体邮件(彩E)系统,并与中国移动的彩信做了对比;
Mobile Radio Service and Their Frequency Plan 移动通信业务及其频谱配置
Image processing is introduced to automatically diagnose and predict the illness of fish. Remote sampling and control of data are realized by mobile general packet radio service ( GPRS) telecommunication technology and Internet technology. 采用图像处理的方法对鱼病进行自动诊断和早期预报,采用移动GPRS无线通讯技术和互联网技术进行远程数据采集和监控。
Heterogeneous wireless network is the trend of next mobile communication technology. Each network has different Radio Access Technology ( RAT), which leads different access access type, system architecture, communication capability and service support. 异构无线网络融合是下一代移动通信技术发展的重要发展趋势,各通信网络的无线接入技术不同,导致了相互间的接入方式、系统架构、通信能力以及业务支持等方面都有所不同。
Both the mobile internet services and the radio& TV service such as CMMB service, interactive TV service and IPTV service are the typical triple play services. 在各类融合业务中,移动互联网业务和广电网的移动多媒体广播电视业务、IPTV业务以及互动电视业务是典型的融合类业务。
Radio Resource Management ( RRM) is the planning and scheduling for the air interface resources of the mobile communication system. It hopes to access as many subscribers as possible with limited radio resource as well as a certain planning coverage and service quality. 无线资源管理是对移动通信系统的空中接口资源的规划和调度,希望在有限的无线资源及保证一定的规划覆盖和服务质量要求的情况下,接入尽可能多的用户。
As a mobile communication system, radio resource management algorithm to optimize the system will directly affect the quality of service ( QoS) from system to user. 对于一个移动通信系统而言,无线资源管理的优化算法将直接影响到系统给用户的服务质量(QoS)。
