## Abstract

The current disclosure proposes per UE customization of the UE DRX/eDRX and PSM based on the analytical results from NWDAF. It also proposes a new UE policy element for UE analytics reporting—UE Analytics Reporting Policy that is a set of reporting rules and is defined by the PCF based on analytical results from NWDAF. The UEARP then is delivered or updated in the UE during registration.

## Claims

### Claim 1

A core network node comprising:
a memory storing instructions; and
at least one processor configured to process the instructions to:
send, to a Network Data Analytic Function (NWDAF) node, an Nnwdaf_AnalyticsInfo Request message comprising: first information, indicating a type of analytics information, and second information, indicating a Subscription Permanent Identifier (SUPI) for the analytics information, and
after the NWDAF node performs data analytics on communication pattern for a
User Equipment (UE) based on the Nnwdaf_AnalyticsInfo_Request message, receive, from the NWDAF node, an Nnwdaf_AnalyticsInfo_Response message comprising:
requested analytics results comprising the first information and the second information; wherein the at least one processor is further configured to process the instructions to:
select a value for a back-off timer for mobility management for the UE based on a communication pattern of the UE.

### Claim 2

A Network Data Analytic Function (NWDAF) node comprising:
a memory storing instructions; and
at least one processor configured to process the instructions to:
receive, from a core network node, an Nnwdaf_AnalyticsInfo Request message comprising: first information, indicating a type of analytics information, and second information, indicating a Subscription Permanent Identifier (SUPI) for the analytics information,
perform data analytics on a communication pattern for a User Equipment (UE) based on the Nnwdaf_AnalyticsInfo Request message, and
send, to the core network node, an Nnwdaf_AnalyticsInfo_Response message comprising requested analytics comprising the first information and the second information; wherein the at least one processor is further configured to process the instructions to:
select a value for a back-off timer for mobility management for the UE based on a communication pattern of the UE.

### Claim 3

A method for a core network node, the method comprising:
sending, to a Network Data Analytic Function (NWDAF) node, an Nnwdaf_AnalyticsInfo Request message comprising: first information, indicating a type of analytics information, and second information, indicating a Subscription Permanent Identifier (SUPI) for the analytics information; and
after the NWDAF node performs data analytics on a communication pattern for a User Equipment (UE) based on the Nnwdaf_AnalyticsInfo Request message, receiving, from the NWDAF node, an Nnwdaf_AnalyticsInfo Response message comprising requested analytics results comprising the first information and the second information;
further comprising:
selecting a value for a back-off timer for mobility management for the UE based on the communication pattern of the UE.

### Claim 4

A method fora Network Data Analytic Function (NWDAF) node, the method comprising:
receiving, from a core network node, an Nnwdaf_AnalyticsInfo Request message comprising: first information, indicating a type of analytics information, and second information, indicating a Subscription Permanent Identifier (SUPI) for the analytics information;
performing data analytics on a communication pattern for a User Equipment (UE) based on the Nnwdaf_AnalyticsInfo Request message; and
sending, to the core network node, an Nnwdaf_AnalyticsInfo Response message comprising requested analytics results comprising the first information and the second information;
further comprising:
selecting a value for a back-off timer for mobility management for the UE based on the communication pattern of the UE.
