Can Anyone please tell me Handover information in LTE is present in which SIB??

Question

Hi All,

I want to know, various types of Attach Request for Phone and Wifi devices and what will be the respective attach Accept response from the network in successful Case. I am looking for Network response both in case if network supports VoLTE (Like RJIO)and if network doesnot supports volte (Airtel)....

Answer 1

As per my understanding of system information blocks, few SIBs contain cell re-selection parameters only not the handover information. An eNodeB executes handover per UE on the basis of measurement report or forcefully from the eNodeB.
Handover signalling uses dedicated signalling messages exchange between eNodeB and UE.

Answer 2

In LTE, UE does not require to read SIB information for performing HO. Source eNodeB sends all required information for HO in rrc reconfiguration to UE. After getting RRC reconfiguration, UE try to latch with target eNodeB and sends rrc reconfiguration complete to target eNodeB with reading any SIB of target eNodeB.
