Abstract

A data transmission method in which a UE initiates a TSC communication request to establish a TSC transmission channel between a first UE and a second UE is provided. The method includes receiving a TSC communication request that is transmitted by a first UE and that carries a first TSC session requirement parameter, determining a QoS requirement of a first service flow and a QoS requirement of a second service flow according to the first TSC session requirement parameter, and transmitting the QoS requirement of the first service flow to a first PCF, the QoS requirement of the first service flow being for being mapped to a QoS policy of the first service flow by using the first PCF, and transmitting the QoS requirement of the second service flow to a second PCF, the QoS requirement of the second service flow being mapped to a QoS policy of the second service flow by using the second PCF, and the QoS policy of the first service flow and the QoS policy of the second service flow being respectively used for establishing a first QoS flow and a second QoS flow by a first SMF and a second SMF. Apparatus and non-transitory computer-readable medium counterpart embodiments are also provided.
