The present disclosure relates to a method and system, for performing an initial network access procedure by a user equipment (UE) to access a network in a coverage area. The method includes performing, by the UE, initialization procedure of the UE. Synchronization, is performed by the UE with one or more base stations to prepare a fast network access index (FNAI) list. An initial network access message (INAM) is multicasted to at least one base station based on an INAM multicast list prepared in response to the FNAI list. At least one initial network access response (INAR) is received from the at least one base station in response to the INAM, each INAR comprising a current load information of a base station. The INAR is processed to determine at least one suitable base station. Synchronization with the suitable base station is performed to access the network in the coverage area.
