Samsung patents 5G roaming method for sharing phone capability data
This filing describes a method for 5G networks to handle data when a phone roams internationally. It outlines how a visited network asks the home network for specific rules on how the phone should route its data, then retrieves that information from the session manager to ensure the connection follows the correct policy.
In the filing’s own words
The present disclosure relates to a communication technique of a 5G communication system for supporting higher data transmission rates than 4G system, and the system. According to the present disclosure, a method performed by a visited-policy control function (V-PCF) of a visited public land mobile network (VPLMN) in a local breakout (LBO) roaming situation includes the steps of transmitting a terminal policy control request message to an H-PCF of a home PLMN (HPLMN), receiving, from the H-PCF, a policy control request trigger (PCRT) for capability information about a terminal related to a UE route selection policy (URSP), transmitting a subscription request for the URSP-related terminal capability information to an SM-PCF managing a packet data unit (PDU) session, receiving the URSP-related terminal capability information from the SM-PCF, and transmitting the URSP-related terminal capability information to the H-PCF.
What exactly they claim (claim 1)
1. A method performed by a visited-policy control function (V-PCF) of a visited public land mobile network (VPLMN) in a local breakout (LBO) roaming situation, the method comprising: transmitting, to an H-PCF of a home PLMN (HPLMN), a terminal policy control request message; receiving, from the H-PCF, a policy control request trigger (PCRT) for capability information of a terminal related to a UE route selection policy (URSP); transmitting, to an SM-PCF managing a packet data unit (PDU) session, a request for subscribing to the capability information of the terminal related to the URSP; receiving, from the SM-PCF, the capability information of the terminal related to the URSP; and transmitting, to the H-PCF, the capability information of the terminal related to the URSP.
