Abstract

Claims (57)

1. A method for controlling at least one user equipment (UE) policy by a UE in a wireless network, the method comprising:

receiving at least one first UE policy from a policy control function (PCF);

performing, in response to receiving the at least one first UE policy, at least one first action from a successful execution of the at least one first UE policy, a failed execution of the at least one first UE policy, and storing of the at least one first UE policy;

transmitting a feedback message to the PCF based on the at least one first action; and

receiving, from the PCF, at least one second UE policy modified from the at least one first UE policy, in response to a number of feedback messages indicating the failed execution of the at least one first UE policy transmitted to the PCF being greater than a threshold value,

wherein based on the at least one first UE policy comprising a wireless local area network selection policy (WLANSP) rule, the feedback message indicating the failed execution of the at least one first UE policy includes reason information of the failed execution indicating that the UE was not able to install the WLANSP rule to connect to a non-3rd generation partnership project (3GPP) network, time information of a handover to the non-3GPP network, and location information including a tracking area or service set identifier (SSID) information.

2. The method of claim 1 , wherein the at least one first UE policy further comprises a UE route selection policy (URSP).

3. The method of claim 2 ,

wherein the URSP comprises:

a storage mechanism for the feedback message,

wherein the feedback message comprises a plurality of status notifications, the plurality of status notifications classified in various categories,

wherein the various categories comprise a failure, alert, warning, mixed criteria based on parameters including identity (ID), timeline, notification status, slices, sub slices, geospatial data, or any other customized dynamic metadata or condition, and the various categories used as query filter criteria, and

wherein the PCF or any other relevant entity access a subset of relevant notifications based on the query filter criteria.

4. The method of claim 2 , wherein the URSP comprises a session and service continuity (SSC) mode selection policy (SSCMSP), a network slice selection policy (NSSP), a data network name (DNN) selection policy, a protocol data unit (PDU) session type policy, a non-seamless offload policy, and an access type preference policy.

5. The method of claim 1 , wherein the feedback message comprises a reason for the failed execution of the at least one first UE policy.

6. A method for controlling at least one user equipment (UE) policy by a policy control function (PCF) in a wireless network, the method comprising:

transmitting at least one first UE policy to a UE;

receiving a feedback message from the UE based on at least one first action performed by the UE based on the at least one first UE policy, wherein the at least one first action is from a successful execution of the at least one first UE policy, a failed execution of the at least one first UE policy, and storing of the at least one first UE policy;

modifying the at least one first UE policy to at least one second UE policy, a number of feedback messages indicating the failed execution of the at least one first UE policy received from the UE being greater than a threshold value; and

transmitting the at least one second UE policy to the UE,

wherein based on the at least one first UE policy comprising a wireless local area network selection policy (WLANSP) rule, the feedback message indicating the failed execution of the at least one first UE policy includes reason information of the failed execution indicating that the UE was not able to install the WLANSP rule to connect to a non-3rd generation partnership project (3GPP) network, time information of a handover to the non-3GPP network, and location information including a tracking area or service set identifier (SSID) information.

7. A user equipment (UE) for controlling at least one UE policy in a wireless network, the UE comprising:

a memory; and

at least one processor coupled to the memory, wherein the at least one processor is configured to:

receive at least one first UE policy from a policy control function (PCF),

perform, in response to receiving the at least one first UE policy, at least one first action from a successful execution of the at least one received UE policy, a failed execution of the at least one first UE policy, and storing of the at least one first UE policy,

transmit a feedback message to the PCF based on the at least one first action, and

receive, from the PCF, at least one second UE policy modified from the at least one first UE policy, in response to a number of feedback messages indicating the failed execution of the at least one first UE policy transmitted to the PCF being greater than a threshold value,

wherein based on the at least one first UE policy comprising a wireless local area network selection policy (WLANSP) rule, the feedback message indicating the failed execution of the at least one first UE policy includes reason information of the failed execution indicating that the UE was not able to install the WLANSP rule to connect to a non-3rd generation partnership project (3GPP) network, time information of a handover to the non-3GPP network, and location information including a tracking area or service set identifier (SSID) information.

8. The UE of claim 7 , wherein the at least one first UE policy further comprises a UE route selection policy (URSP).

9. The UE of claim 8 ,

wherein the URSP comprises:

a storage mechanism for the feedback message,

wherein the feedback message comprises a plurality of status notification, the plurality of status notification classifies in various categories,

wherein the various categories comprise a failure, alert, warning, mixed criteria based on parameters including Identity (ID), timeline, notification status, slices, sub slices, geospatial data, or any other customized dynamic metadata or condition,

wherein the various categories are used as query filter criteria, and

wherein the PCF or any other relevant entity access a subset of relevant notifications based on the query filter criteria.

10. The UE of claim 8 , wherein the URSP comprises a session and service continuity (SSC) mode selection policy (SSCMSP), a network slice selection policy (NSSP), a data network name (DNN) selection policy, a protocol data unit (PDU) session type policy, a non-seamless offload policy, and an access type preference policy.

11. The UE of claim 8 , wherein the feedback message comprises a reason for the failed execution of the at least one first UE policy.

12. An apparatus for implementing policy control function (PCF) for controlling at least one user equipment (UE) policy in a wireless network, the PCF comprising:

a memory; and

at least one processor coupled to the memory, wherein the at least one processor is configured to:

transmit at least one first UE policy to a UE,

receive a feedback message from the UE based on at least one first action performed by the UE based on the at least one first UE policy, wherein the at least one first action is from a successful execution of the at least one first UE policy, a failed execution of the at least one first UE policy, and storing of the at least one first UE policy,

modify the at least one first UE policy to at least one second UE policy, a number of feedback messages indicating the failed execution of the at least one first UE policy received from the UE being greater than a threshold value, and

transmit the at least one second UE policy to the UE,
