System and method for network registration in mobile telecommunications

A terminal to perform a network registration, comprising:

• a processor;
• a radio frequency transmitter/receiver;
• and
• a Non Access Stratum (NAS) and an Access Stratum (AS),
• wherein the terminal receives public land mobile network (PLMN) information from a first PLMN, the PLMN information comprising first PLMN information and second PLMN information on a second PLMN in a region near the first PLMN, obtains an available PLMN list from the PLMN information, selects the second PLMN corresponding to a network registration object by referring to the available PLMN list, and attempts a network registration to the second PLMN, and
• wherein the first PLMN corresponds to a first mode and the second PLMN corresponds to a second mode.

A public land mobile network (PLMN) for a network registration in mobile telecommunications, comprising:

• a radio frequency transmitter/receiver;
• a processor;
• and
• a memory to store PLMN information comprising its own PLMN information and information on a second PLMN in a region near the PLMN,
• wherein the PLMN transmits the PLMN information to a terminal if a network registration to the PLMN by the terminal fails.

A method for a network registration to a multi-mode public land mobile network (PLMN), comprising:

• attempting a network registration to a first PLMN;
• receiving PLMN information comprising first PLMN information and second PLMN information on a second PLMN in a region near the first PLMN if the network registration to the first PLMN fails;
• obtaining an available PLMN list from the PLMN information;
• and
• attempting the network registration to the second PLMN selected as a network registration object by referring to the available PLMN list,
• wherein the first PLMN corresponds to a first mode and the second PLMN corresponds to a second mode.
