Samsung patents method for managing data handoff for roaming 5G users
Samsung has been granted a patent for a method that helps 5G networks manage data connections for users traveling in foreign countries. The system allows the home network to check if a roaming device is allowed to send specific types of non-Internet data through the local network.
In the filing’s own words
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.
What exactly they claim (claim 1)
1. 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.
