Hi to everyone,
how much energy a handover execution cost to a UserEquipment?
I mean from the energetic point of view the whole handover Processing/Signaling is made in the enBs and MME, the only amount of energy spent in the user equipment other than the measurement report that triggers the HO is the energy spent is in the RRC Configuration (SETTING THE RADIO INTERFACE TO COMMUNICATE TO HenB ).
Anyone has some reference about the RRC Reconfiguration cost in energy for the User Equipment?
I have been looking in the internet but there are just papers talking about the consumption on the multimedia applications, but not how much the signalling costs for a UE.

As part of S1-AP procedure with MME relocation, Handover Required message sent to source MME. Target eNodeBId is present within the handover required. How source MME figure out target cell is being served by XYZ MME and sends "Forward relocation Request" message to XYZ MME.
