Method for transmitting and receiving paging signal in wireless communication system and apparatus therefor

A user equipment (UE) receiving a paging signal from a plurality of networks in a wireless communication system, the UE comprising:

• a radio frequency (RF) module configured to transmit and receive a radio signal;
• at least one processor functionally connected to the RF module;
• and
• at least one computer memory operationally connected to the at least one processor,
• wherein the at least one computer memory is configured to store, upon execution, instructions that allow the at least one processor to:
• perform a registration to the plurality of networks;
• obtain a plurality of monitoring time points that has to check whether a paging message is received from each of the plurality of networks;
• when at least some of the plurality of monitoring time points overlap, transmit, to a first network, a change request of a first monitoring time point that has to check whether a first paging message is received from the first network of the plurality of networks;
• receive, from the first network, configuration information related to the request;
• and
• update the first monitoring time point based on the configuration information.

A method of transmitting, by a first network, a paging signal in a wireless communication system, the method comprising:

• performing a registration for a user equipment (UE);
• when there is an overlap between at least some of a plurality of monitoring time points that has to check whether a paging message is received from each of a plurality of networks including the first network, receiving, from the UE, a change request of a first monitoring time point that has to check whether a first paging message of the first network is received;
• transmitting, to the UE, configuration information related to the request;
• and
• transmitting the first paging message to the UE based on the configuration information.

A first network transmitting a paging signal to a user equipment (UE) in a wireless communication system, the first network comprising:

• a radio frequency (RF) module configured to transmit and receive a radio signal;
• at least one processor functionally connected to the RF module;
• and
• at least one computer memory operationally connected to the at least one processor,
• wherein the at least one computer memory is configured to store, upon execution, instructions that allow the at least one processor to:
• perform a registration for the UE;
• when there is an overlap between at least some of a plurality of monitoring time points that has to check whether a paging message is received from each of a plurality of networks including the first network, receive, from the UE, a change request of a first monitoring time point that has to check whether a first paging message of the first network is received;
• transmit, to the UE, configuration information related to the request;
• and
• transmit the first paging message to the UE based on the configuration information.
