Method for transceiving paging message in wireless communication system and apparatus for same
Disclosed are a method for transceiving a paging message in a wireless communication system that supports a multiple radio access network and an apparatus for the method. In detail, the method comprises: a step of receiving, from a terminal, a paging redirection request message for requesting redirection of a paging message transmission path of a cellular network through a wireless local area network (WLAN) access point (AP) in the event the terminal accessed to a base station of the cellular network has switched the access thereof to the WLAN AP; a step of transmitting a paging redirection response message indicating whether the redirection of the paging message is authenticated or not to the terminal through the WLAN AP; and a step of transmitting a paging message to the terminal through the WLAN AP.
1. A method for transmitting a paging message in a wireless communication system supporting multiple radio access networks, the method comprising:
receiving a paging redirection request message to request to change a path of the paging message of a cellular network from a user equipment (UE), which is connected to a base station of the cellular network, via a wireless local area network (WLAN) access point (AP) when the UE is reconnected to the WLAN AP;
transmitting a paging redirection response message indicating whether the request of the paging redirection request message is accepted, via the WLAN AP to the UE; and
transmitting the paging message via the WLAN AP to the UE,
wherein the paging redirection request message comprises paging interval request information determined using a transmission cycle of the paging message, which is configured by the cellular network.
2. The method according to claim 1 , wherein the paging redirection response message comprises paging interval information of the paging message, which is determined based on the paging interval request information.
3. The method according to claim 1 , further comprising periodically receiving a UE association state report message comprising an identifier of the WLAN AP, from the UE via the WLAN AP.
4. The method according to claim 3 , wherein the identifier of the WLAN AP comprises an Internet protocol (IP) address of the WLAN AP or a medium access control (MAC) address of the WLAN AP.
5. An apparatus for transmitting a paging message in a wireless communication system supporting multiple radio access networks, the apparatus comprising:
a transceiving module for transceiving wired/wireless signals; and
a processor is configured to receive a paging redirection request message to request to change a path of the paging message of a cellular network from a user equipment (UE), which is connected to a base station of the cellular network, via a wireless local area network (WLAN) access point (AP) when the UE is reconnected to the WLAN AP, to transmit a paging redirection response message indicating whether the request of the paging redirection request message is accepted, via the WLAN AP to the UE, and to transmit the paging message via the WLAN AP to the UE,
wherein the paging redirection request message comprises paging interval request information determined using a transmission cycle of the paging message, which is configured by the cellular network.
6. The apparatus according to claim 5 , wherein the paging redirection response message comprises paging interval information of the paging message, which is determined based on the paging interval request information.
7. The apparatus according to claim 5 , wherein the processor is configured to periodically receive a UE association state report message comprising an identifier of the WLAN AP, from the UE via the WLAN AP.
8. The apparatus according to claim 7 , wherein the identifier of the WLAN AP comprises an Internet protocol (IP) address of the WLAN AP or a medium access control (MAC) address of the WLAN AP.
