The various embodiments of the present invention provide a method and system for notifying, a system information modification in at least one of a MIB/SIB1. The method comprises of transmitting a system information in a first modification period by an eNodeB, verifying the system information at eNodeB to check if the system information is to be modified in a modification period succeeding the first modification period, checking at eNodeB if only the system information corresponding to the at least one of the MIB or the SIB1 is modified, fetching the modified system information without initiating a paging procedure if only the MIB/SIB1 is modified and transmitting the modified system information in a succeeding modification period to the system information transmission module. The UE acquires the MIB/SIB1 at a start of each modification period.
