Abstract
The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate and, more specifically, to a method for controlling transmission of non-Internet protocol (non-IP) address data of a roaming terminal in unified data management (UDM) of a wireless communication system.
Claims20
A method for a unified data management (UDM) of a wireless communication system to control transmission of a non-Internet protocol (non-IP) address data of a roaming terminal, the method comprising:
- receiving, from an access and mobility management function (AMF) that has registered the roaming terminal in a visited public land mobile network (VPLMN), a subscriber information request message of the roaming terminal;
- providing, to the AMF, subscriber information of the roaming terminal;
- receiving, from a network exposure function (NEF) located in a home public land mobile network (HPLMN), a non-IP data delivery (NIDD) authorization request message including configuration information indicating whether NIDD of the roaming terminal passes through the NEF;
- and
- updating terminal subscriber information of the roaming terminal based on the received NIDD authorization request message,
- wherein the terminal subscriber information comprises a session management subscription data and a session management function (SMF) selection subscription data.
A unified data management (UDM) device for controlling transmission of non-Internet protocol (non-IP) address data of a roaming terminal in a wireless communication system, the UDM device comprising:
- a network interface configured to communicate with other network functional devices;
- a memory configured to store terminal information;
- and
- at least one processor,
- wherein the at least one processor is configured to:
- receive, from an access and mobility management function (AMF) that has registered the roaming terminal in a visited public land mobile network (VPLMN), a subscriber information request message of the roaming terminal,
- provide subscriber information of the roaming terminal to the AMF,
- receive, from a network exposure function (NEF) located in a home public land mobile network (HPLMN), a non-IP data delivery (NIDD) authorization request message including configuration information indicating whether NIDD of the roaming terminal passes through the NEF, and
- update terminal subscriber information of the roaming terminal based on the received NIDD authorization request message,
- wherein the terminal subscriber information comprises a session management subscription data and a session management function (SMF) selection subscription data.
