Abstract

A UE is configured with a first parameter indicating whether the UE is allowed to start robust paging function and a second parameter indicating the maximum number of consecutive legacy paging messages the UE has to fail to receive before the robust paging function is started. The UE's processor monitors a legacy paging occasion to receive a legacy paging message, determines that the number of consecutive legacy paging occasions that the UE fails to receive legacy paging messages has reached the value of the second parameter, starts the robust paging function after determining that the value of the first parameter indicates that the UE is allowed to start the robust paging function, and the number of consecutive legacy paging occasions that the UE fails to receive the legacy paging messages has reached the value of the second parameter, and monitors a robust paging occasion to receive a robust paging message.

First claim

What is claimed is:

1 . A user equipment (UE), comprising:
one or more non-transitory computer-readable media storing one or more computer-executable instructions for configuring the UE with different types of paging functions, wherein the UE is configured with: a first parameter indicating whether the UE is allowed to start a paging function of a second type that is different from a paging function of a first type, a second parameter indicating a maximum number of consecutive paging messages of the first type the UE has to fail to receive before the paging function of the second type is started, and a third parameter indicating a maximum number of consecutive paging messages of a second type the UE has to fail to receive before the paging function of the second type is stopped; and at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the one or more computer-executable instructions to cause the UE to:
monitor, during the paging function of the first type, a paging occasion of the first type to receive a paging message of the first type;
after failing to receive the paging message of the first type during the paging occasion of the first type, increment a number of consecutive paging occasions of the first type the UE fails to receive paging messages of the first type;
determine that the number of consecutive paging occasions of the first type the UE fails to receive the paging messages of the first type has reached a value of the second parameter;
start the paging function of the second type after determining that (i) a value of the first parameter indicates that the UE is allowed to start the paging function of the second type, and (ii) the number of consecutive paging occasions of the first type the UE fails to receive the paging messages of the first type has reached the value of the second parameter; and
monitor, during the paging function of the second type, a paging occasion of the second type to receive a paging message of the second type.

2 . The UE of claim 1 , wherein the at least one processor is further configured to execute the one or more computer-executable instructions to cause the UE to:
in a case that a paging message of the second type is received by the UE:
retrieve a message identity index from the paging message of the second type, and
retrieve a string identified by the message identity index; and
in a case that the UE fails to receive a paging message of the second type during the paging occasion of the second type:
increment a number of consecutive paging occasions of the second type during which the UE fails to receive paging messages of the second type, and
stop the paging function of the second type in a case that the number of consecutive paging occasions of the second type during which the UE fails to receive the paging messages of the second type reaches a value of the third parameter.

3 . The UE of claim 2 , further comprising:
a display, wherein the at least one processor is further configured to execute the one or more computer-executable instructions to cause the UE to:
display the string identified by the message identity on the display of the UE.

4 . The UE of claim 1 , wherein:
the UE is further configured with a fourth parameter indicating whether the UE supports concurrent monitoring of the paging messages of the first and second types, and the at least one processor is further configured to execute the one or more computer-executable instructions to cause the UE to:
concurrently monitor for the paging messages of the first and second types in a case that the paging function of the second type is started, and the fourth parameter indicates that the UE supports the concurrent monitoring of the paging messages of the first and second types.

5 . The UE of claim 4 , wherein the at least one processor is further configured to execute the one or more computer-executable instructions to cause the UE to:
monitor for the paging messages of the first type and not monitor for the paging messages of the second type in a case that either a paging message of the first type is received, a paging message of the second type is received, or the number of consecutive paging occasions of the second type during which the UE fails to receive the paging messages of the second type reaches the value of the third parameter.

6 . The UE of claim 1 , wherein:
the UE is further configured with a fourth parameter indicating whether the UE supports concurrent monitoring of the paging messages of the first and second types, and the at least one processor is further configured to execute the one or more computer-executable instructions to cause the UE to:
monitor for the paging messages of the second type and not monitor for the paging messages of the first type in a case that the paging function of the second type is started, and the fourth parameter indicates that the UE does not support the concurrent monitoring of the paging messages of the first and second types.

7 . The UE of claim 6 , wherein the at least one processor is further configured to execute the one or more computer-executable instructions to cause the UE to:
monitor for the paging messages of the first type and not monitor for the paging messages of the second type in a case that either a paging message of the second type is received, or the number of consecutive paging occasions of the second type during which the UE fails to receive the paging messages of the second type reaches the value of the third parameter.

8 . The UE of claim 1 , wherein the at least one processor is further configured to execute the one or more computer-executable instructions to cause the UE to:
receive a downlink control information (DCI) message comprising a fourth parameter indicating a number of times a paging message of the second type is retransmitted during each paging occasion of the second type; identify a plurality of paging messages of the second type that are retransmitted during the paging occasion of the second type based on the fourth parameter; and aggregate a correctly decoded part of each of two or more paging messages of the plurality of paging messages of the second type that are retransmitted during the paging occasion of the second type to construct a fully decoded paging message of the second type.

9 . The UE of claim 1 , wherein:
the UE is configured with a fourth parameter indicating a number of times a paging message of the second type is to be retransmitted during each paging occasion of the second type, the fourth parameter is configured to the UE either at a time of manufacturing the UE or through one of a radio resource control (RRC) message, a non-access-stratum (NAS) message, a system information block (SIB) message, or a medium access control (MAC) control element (CE) message, and the at least one processor is further configured to execute the one or more computer-executable instructions to cause the UE to:
identify a plurality of paging messages of the second type that is retransmitted during a paging occasion of the second type based on the fourth parameter; and
aggregate a correctly decoded part of each of two or more paging messages of the plurality of paging messages of the second type that is retransmitted during the paging occasion of the second type to construct a fully decoded paging message of the second type.

10 . The UE of claim 1 , wherein the first, second, and third parameters are configured to the UE at a time of manufacturing the UE.

11 . The UE of claim 1 , wherein the at least one processor is further configured to execute the one or more computer-executabl
