METHOD FOR LOCATION AREA UPDATE IN MULTI-RAT ENVIRONMENT AND METHOD FOR TRANSMITTING/RECEIVING PAGING INFORMATION

摘要

The present invention relates to a method for updating a TAC in a multi-RAT environment and a method for transmitting/receiving paging information. A terminal, which is capable of establishing a radio connection through a first radio interface by a first radio protocol and a radio connection through a second radio interface by a second radio protocol, may determine the best radio interface on the basis of predetermined conditions, perform a TA update through the best radio connection interface, and transmit/receive paging information through the best radio connection interface.

1. A method for location area update and transmitting and receiving paging information by a user equipment, comprising:
determining an optimal radio access interface based on a predetermined condition, if there exist a radio access network through a first radio interface by a first radio protocol and a radio access network through a second radio interface by a second radio protocol; performing tracking area (TA) update through the optimal radio access interface; and transmitting and receiving paging information through the optimal radio access interface.
