Abstract

A user equipment (UE) includes a transceiver and a processor. The transceiver is configured to receive, from a network, a paging message including an indication for delayed paging. The indication for delayed paging indicates that the UE is allowed to delay a response to the paging message. The processor is configured to identify the indication for delayed paging in the paging message.

First claim

What is claimed is:

1. A method for a user equipment (UE), the method comprising:
transmitting capability information of delayed paging to a network;
receiving at least one delayed paging message including an indication indicating that the UE is allowed to delay a response to one of the at least one delayed paging message, based on the capability information; and
determining to transmit a response to the one of the at least one delayed paging message with delay based on the indication.

2. The method according to claim 1 , wherein
the receiving the at least one delayed paging message is performed based on a restriction from a policy control function.

3. The method according to claim 1 , wherein
the receiving the at least one delayed paging message is performed based on a location of the UE or a time.

4. The method according to claim 1 , wherein
the at least one delayed paging message includes information of a repetition number for the delayed paging and information of a time interval for the delayed paging.

5. The method according to claim 1 , wherein
the capability information is transmitted in a non access stratum (NAS) message or a radio resource control (RRC) message.

6. The method according to claim 1 , further comprising:
checking whether a radio coverage condition is good for responding in a case where the at least one delayed paging message includes the indication, and wherein
the determining to transmit the response is performed in a case where checking that the radio coverage condition is good for responding.

7. A method for a core network node, the method comprising:
receiving capability information of delayed paging from a user equipment (UE);
transmitting at least one delayed paging message including an indication indicating that the UE is allowed to delay a response to one of the at least one delayed paging message to the UE, based on the capability information; and
receiving a response to the one of the at least one delayed paging message with delay based on the indication.

8. The method according to claim 7 , wherein
the transmitting the at least one delayed paging message is performed based on a restriction from a policy control function.

9. The method according to claim 7 , wherein
the transmitting the at least one delayed paging message is performed based on a location of the UE or a time.

10. The method according to claim 7 , wherein
the transmitting the at least one delayed paging message is performed based on information of a repetition number for delayed paging and information of a time interval for delayed paging.

11. The method according to claim 7 , wherein
the capability information is transmitted in a non access stratum (NAS) message or a radio resource control (RRC) message.

12. A user equipment (UE) comprising:
a memory storing instructions; and
at least one processor configured to process the instructions to:
transmit capability information of delayed paging to a network;
receive at least one delayed paging message including an indication indicating that the UE is allowed to delay a response to one of the at least one delayed paging message from the network, based on the capability information; and
determine to transmit a response to the one of the at least one delayed paging message with delay based on the indication.

13. A core network node comprising:
a memory storing instructions; and
at least one processor configured to process the instructions to:
receive capability information of delayed paging from a user equipment (UE);
transmit at least one delayed paging message including an indication indicating that the UE is allowed to delay a response to one of the at least one delayed paging message to the UE, based on the capability information; and
receive a response to one of the at least one delayed paging message with delay based on the indication.
