Handover between 3G & 3G LTE
Real-time < 300ms
Non-real-time < 500ms
LTE is aimed at minimizing cost and power consumption while ensuring backward-compatibility and a cost effective migration from UMTS systems. Enhanced multicast services, enhanced support for end-to-end Quality of Service (QoS) and minimization of the number of options and redundant features in the architecture are also being targeted.
The spectral efficiency in the LTE DownLink (DL) will be 3 to 4 times of that of Release 6 HSDPA while in the UpLink (UL), it will be 2 to 3 times that of Release 6 HSUPA. The handover procedure within LTE is intended to minimize interruption time to less than that of circuit-switched handovers in 2G networks. Moreover the handovers to 2G/3G systems from LTE are designed to be seamless.
