Samsung patents 5G method to negotiate data quality for apps
Samsung has filed a patent for a method in 5G and 6G networks that allows applications to request specific data transfer quality levels. The system uses a network exposure function to negotiate these policies with a policy control function, ensuring the network supports the app's needs.
In the filing’s own words
The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a network exposure function (NEF) entity in a wireless communication system, according to the present disclosure, may comprise the steps of: receiving, from an application function (AF) entity, a first message requesting negotiation of a planned data transfer with QoS (PDTQ) policy; on the basis of the first message, transmitting, to a policy control function (PCF) entity, a second message requesting a decision of the PDTQ policy; receiving, from the PCF entity, a third message including information related to at least one PDTQ policy determined by the PCF entity; and transmitting, to the AF entity, information related to the determined at least one PTDQ policy.
What exactly they claim (claim 1)
1. A method performed by a network exposure function (NEF) entity in a wireless communication system, the method comprising: receiving, from an application function (AF) entity, a first message requesting negotiation of a planned data transfer with QoS (PDTQ) policy; transmitting, to a policy control function (PCF) entity, a second message requesting identification of the PDTQ policy, based on the first message; receiving, from the PCF entity, a third message comprising information related to at least one PDTQ policy identified by the PCF entity; and transmitting, to the AF entity, the information related to the at least one identified PDTQ policy.
