Hi Sri Thank you for the very interesting presentation at 115 last week.
I’d like to make some comments about your proposal which I think has much wider implications than ‘just’ the air interface. 1. We have a mechanism in LTE/6G for ensuring delivery of packets in a more expeditious manner – IMS. It has the benefit of tying the capabilities and performance of the air interface to the packet core. Other than for VoLTE/VoNR, we have never used its full potential! We even have multiple classes of service defined already… 1. We need to channel our inner George Orwell. ‘All [packets] are created equal, but some are more equal than others.’ Understanding the requirements of a specific application especially where the access media is highly limited is important. Unlike wireleine, 5G/6G/whateverG are unlikely to reduce in price and increase in capacity yet Internet access is 92% over these technologies now. We have to start understanding the applications and matching ‘network’ resources accordingly. 1. Each UE has a TFT as the way of steering traffic into the ‘correct’ bearer at the correct QCI/5QI. To-date, this is very rough – simple 5-tuple – but there is no reason why this could not be expanded to take input from metadata in the manner you suggest. So I have a proposal. * We design an API between the TFT and the application which enables specific packets (e.g. the I-Frame) to be marked in some manner. * This should be marked so that any encryption is maintained. * By ‘application’ I think we need to consider that application = UE app + data centre app NOT a ‘app’ on the UE. * Traffic which requires a higher level of handling is transported in the dedicated bearer with the correct QCI/5QI and associated radio numerology. Outside of the scope of this group but of wider interest would be how I could maintain that QCI and packet treatment beyond the SGi/N6 interface across other packet networks to/from the data source.
