蜂窝式无线网络通常是在同一个技术组内实现进一步的发展。例如,3GPP的技术,通常是根据3GPP2的cdma2000标准通过GSM,UMTS,HSPA和LTE来实现的。但是,多家网络运营商最近决定将其现有的EV-DO网络升级到LTE,这通常牵涉到继续使用EV-DO网络。毕竟该网络已大大优化,并拥有广泛的用户基础。因此,对EV-DO网络的现有投入仍将是一个因素。与此同时,LTE网络会首先用于扩展现有的数据服务。罗德与施瓦茨公司Jurgen Schlienz所撰《LTE与EV-DO间的切换》一文对优化切换的体系结构,LTE与EV-DO之间的切换进行了详细介绍。可供业内人士参考。
Cellular wireless networks are usually further developed within the same technology group. For example, the technology of 3GPP is generally implemented by GSM, UMTS, HSPA and LTE according to the cdma2000 standard of 3GPP2. However, several network operators recently decided to upgrade their existing EV-DO network to LTE, which typically involves continuing to use the EV-DO network. After all, the network has been greatly optimized and has a broad user base. Therefore, the existing investment in the EV-DO network will still be a factor. In the meantime, LTE networks will be used first to extend existing data services. The article “Switching Between LTE and EV-DO” authored by Rohde & Schwarz Jurgen Schlienz discusses the architecture of optimized handovers and the handoff between LTE and EV-DO. For the industry reference.
