Abstract
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for replacement of a DNN and/or S-NSSAI in a wireless communication system is provided.
Claims20
A method performed by an access and mobility management function (AMF) in a mobile communication system, the method comprising:
- transmitting, to a policy control function (PCF), a first message for requesting a policy association;
- and
- as a response to the first message, receiving, from the PCF, a second message including policy information related to a data network name (DNN) replacement,
- wherein the policy information includes single network slice selection assistance information (S-NSSAI) and a list of one or more DNNs for the S-NSSAI.
A method performed by a policy control function (PCF) in a mobile communication system, the method comprising:
- receiving, from an access and mobility management function (AMF), a first message for requesting a policy association;
- and
- as a response to the first message, transmitting, to the AMF, a second message including policy information related to a data network name (DNN) replacement,
- wherein the policy information includes single network slice selection assistance information (S-NSSAI) and a list of one or more DNNs for the S-NSSAI.
An access and mobility management function (AMF) in a mobile communication system, the AMF comprising:
- a transceiver;
- and
- a controller configured to:
- transmit, to a policy control function (PCF) via the transceiver, a first message for requesting a policy association, and
- as a response to the first message, receive, from the PCF via the transceiver, a second message including policy information related to a data network name (DNN) replacement,
- wherein the policy information includes single network slice selection assistance information (S-NSSAI) and a list of one or more DNNs for the S-NSSAI.
A policy control function (PCF) in a mobile communication system, the PCF comprising:
- a transceiver;
- and
- a controller configured to:
- receive, from an access and mobility management function (AMF) via the transceiver, a first message for requesting a policy association;
- and
- as a response to the first message, transmit, to the AMF via the transceiver, a second message including policy information related to a data network name (DNN) replacement,
- wherein the policy information includes single network slice selection assistance information (S-NSSAI) and a list of one or more DNNs for the S-NSSAI.
