摘要
从业务流程的视角对UMTS系统和LTE系统进行了对比分析,直观地说明了LTE系统比UMTS系统在设计上的合理性和先进性。通过一些关键流程,如RRC连接建立、附着过程、会话过程,简明扼要地解释了LTE系统的时效性高于UMTS系统的原因。
From the perspective of service procedure, this paper compares and analyzes UMTS and LTE system, and visually shows us why the design of LTE system is more reasonable and more advanced than UMTS system. Through some key procedures （comparison）, such as RRC connection setup procedure, attach procedure and create session procedure, this paper briefly explains why LTE system is more efficient than UMTS system.
