Claims:WE CLAIM:

1. A method of performing an initial network access procedure by a user equipment to access a network in a coverage area, the method comprising:
performing, by the user equipment (UE), an initialization procedure of the UE;
synchronizing, by the UE, with one or more base stations to prepare a fast network access index (FNAI) list;
multicasting, by the UE, an initial network access message (INAM) to at least one base station of the one or more base stations based on an INAM multicast list, the INAM multicast list being prepared in response to the FNAI list;
receiving, by the UE, at least one initial network access response (INAR) from the at least one base station of the one or more base stations in response to the INAM, each INAR comprising a current load information of a base station to indicate post latching service suitability of the at least one base station;
processing, by the UE, the at least one INAR to determine at least one suitable base station; and
synchronizing, by the UE, with the suitable base station to access the network in the coverage area.

2. The method as claimed in claim 1, wherein performing the initialization procedure of the UE comprises one of:
initializing the UE during start-up of the UE;
initializing the UE during rebooting of the UE; and
initializing the UE during re-latching of the UE.

3. The method as claimed in claim 1, wherein synchronizing with the one or more base stations comprises:
scanning a primary synchronization signal (PSS) and an extended secondary synchronization signal (ESSS) for each of the one or more base stations to generate synchronization results, the FNAI list being prepared during the scanning; and
providing, by a UE radio subsystem (UE-RSS) of the UE, the synchronization results to a UE data subsystem (UE-DSS).

4. The method as claimed in claim 3, wherein the FNAI list comprises cell identification number, an FNAI, and an offset time between the one or more base stations, the offset time being added in the INAM to inform the base station to transmit the INAR on expiry of the offset time from receipt of the INAM.

5. The method as claimed in claim 3, wherein the INAM multicast list is prepared by:
fetching, by the UE-DSS, network access related information (NARI); and
preparing, by the UE-DSS, the INAM multicast list based on the NARI.

6. The method as claimed in claim 5, wherein the NARI is fetched based on an FNAI of the base station that is encoded within the ESSS.

7. The method as claimed in claim 6, wherein the INAR is prepared by the base station on decoding the INAM received from the UE.

8. The method as claimed in claim 1, wherein the current load information is based on factors comprising a current throughput of the base station, a guaranteed bit rate subscription of the UE, number of UE, supported UE, and core network overloading condition.

9. The method as claimed in claim 1 and further comprising:
registering, by the UE, with the suitable base station by transmitting a registration request to the suitable base station.

10. A user equipment for performing an initial network access procedure to access a network in a coverage area, the user equipment comprising:
a processor; and
a memory, communicatively coupled to the processor, wherein the memory stores processor-executable instructions, which, on execution, causes the processor to:
perform an initialization procedure of the user equipment (UE);
synchronize with one or more base stations to prepare a fast network access index (FNAI) list;
multicast an initial network access message (INAM) to at least one base station of the one or more base stations based on an INAM multicast list, the INAM multicast list being prepared in response to the FNAI list;
receive at least one initial network access response (INAR) from the at least one base station of the one or more base stations in response to the INAM, each INAR comprising a current load information of a base station to indicate post latching service suitability of the at least one base station;
process the at least one INAR to determine at least one suitable base station; and
synchronize with the suitable base station to access the network in the coverage area.

11. The UE as claimed in claim 10, wherein the processor is further configured to perform the initialization procedure of the UE by one of:
initializing the UE during start-up of the UE;
initializing the UE during rebooting of the UE; and
initializing the UE during re-latching of the UE.

12. The UE as claimed in claim 10, wherein the processor is further configured to synchronize with the one or more base stations by:
scanning a primary synchronization signal (PSS) and an extended secondary synchronization signal (ESSS) for each of the one or more base stations to generate synchronization results, the FNAI list being prepared during the scanning; and
providing, by a UE radio subsystem (UE-RSS) of the UE, the synchronization results to a UE data subsystem (UE-DSS).

13. The UE as claimed in claim 12, wherein the FNAI list comprises cell identification number, an FNAI, and an offset time between the one or more base stations, the offset time being added in the INAM to inform the base station to transmit the INAR on expiry of the offset time from receipt of the INAM.

14. The UE as claimed in claim 12, wherein the INAM multicast list is prepared by:
fetching, by the UE-DSS, network access related information (NARI); and
preparing, by the UE-DSS, the INAM multicast list based on the NARI.

15. The UE as claimed in claim 14, wherein the NARI is fetched based on an FNAI of the base station that is encoded within the ESSS.

16. The UE as claimed in claim 15, wherein the INAR is prepared by the base station on decoding the INAM received from the UE.

17. The UE as claimed in claim 10, wherein the current load information is based on factors comprising a current throughput of the base station, a guaranteed bit rate subscription of the UE, number of UE, supported UE, and core network overloading condition.

18. The UE as claimed in claim 10, wherein the processor is further configured to:
register with the suitable base station by transmitting a registration request to the suitable base station.
