Along with LTE introduction, 3GPP also standardized Single Radio Voice Call Continuity (SRVCC) in Release 8 specifications to provide seamless continuity when an UE handovers from LTE coverage (E-UTRAN) to UMTS/GSM coverage (UTRAN/GERAN).
3GPP network sharing architecture allows different core network operators to connect to a shared radio access network.
The X2AP protocol is used to handle the UE mobility within E-UTRAN and provides the following functions:
UE class determines the speed at which data can be transferred in uplink and downlink directions. For GPRS & UMTS, most of us already are aware of it.
3GPP has already started work on Release 11. See objectives of features & study items from 3GPP Work Items below.
Intra E-UTRAN Handover is used to hand over a UE from a source eNodeB to a target eNodeB using X2 when the MME is unchanged. In the scenario described here Serving GW is also unchanged.
In LTE E-UTRAN measurements to be performed by a UE for mobility are classified as below
UE Positioning function is required to provide the mechanisms to support or assist the calculation of the geographical position of a UE.

August 14, 2009 | LTE standards are in matured state now with release 8 frozen. While LTE Advanced is still under works. Often the LTE standard is seen as 4G standard which is not true.
