Device and method for policy management of user equipment in wireless communication system
The present disclosure relates to a pre-5 th -Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4 th -Generation (4G) communication system such as Long Term Evolution (LTE). An operating method of a policy control function (PCF) node in a wireless communication system, according to various embodiments of the present disclosure, comprises the steps of: determining, on the basis of preset conditions, whether to transmit a user equipment (UE) policy; transmitting a message including the UE policy; and receiving information related to a result of a policy section (PS) operation performed by a UE on the basis of the UE policy.
1. A method for operating a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from an access and mobility management function (AMF) node, an identity request message for requesting a permanent equipment identifier (PEI) of the UE;
transmitting, to the AMF node, the PEI of the UE; and
receiving, from a policy control function (PCF) node, a UE route selection policy (URSP) rule associated with an operating system of the UE,
wherein the operating system of the UE is based on the PEI of the UE,
wherein the URSP rule includes an application identifier related to the operating system of the UE and a validation criteria associated with a validity of the URSP rule, and
wherein the validation criteria includes at least one of time criteria or location criteria.
2. The method of claim 1 , wherein an operating system identifier (OSId) of the UE is identified from the PEI by the PCF, based on mapping relationship between PEIs and OSIds.
3. The method of claim 2 , wherein the OSId is stored in a user data repository (UDR).
4. A method for operating a policy control function (PCF) node in a wireless communication system, the method comprising:
receiving, from an access and mobility management function (AMF) node, a permanent equipment identifier (PEI) of a user equipment (UE);
obtaining an operating system of the UE, based on the PEI of the UE; and
transmitting, to the UE, a UE route selection policy (URSP) rule associated with the operating system of the UE,
wherein the URSP rule includes an application identifier related to the operating system of the UE and a validation criteria associated with a validity of the URSP rule, and
wherein the validation criteria includes at least one of time criteria or location criteria.
5. The method of claim 4 , wherein the PEI of the UE is transmitted from the UE to the AMF node, in response to an identity request message for requesting the PEI, which is transmitted from the AMF node.
6. The method of claim 4 , further comprising:
identifying an operating system identifier (OSId) of the UE from the PEI, based on mapping relationship between PEIs and OSIds.
7. The method of claim 6 , further comprising:
storing the OSId in a user data repository (UDR).
8. A user equipment (UE) in a wireless communication system, the UE comprising:
a transceiver; and
at least one processor functionally coupled to the transceiver, and configured to control the transceiver,
wherein the at least one processor is configured to:
receive, from an access and mobility management function (AMF) node, an identity request message for requesting a permanent equipment identifier (PEI) of the UE,
transmit, to the AMF node, the PEI of the UE, and
receive, from a policy control function (PCF) node, a UE route selection policy (URSP) rule associated with an operating system of the UE,
wherein the operating system of the UE is based on the PEI of the UE,
wherein the URSP rule includes an application identifier related to the operating system of the UE and a validation criteria associated with a validity of the URSP rule, and
wherein the validation criteria includes at least one of time criteria or location criteria.
9. The UE of claim 8 , wherein an operating system identifier (OSId) is identified from the PEI by the PCF, based on mapping relationship between PEIs and OSIds.
10. The UE of claim 9 , wherein the OSId is stored in a user data repository (UDR).
