A Solution for Establishing Traffic Routes per Application in 5G-Advanced and 6G Mobile Networks.

With the spread of technologies such as cloud computing, IoT, and AI, as well as 5G, future new services require more powerful programmability and simpler network solutions. SRv6 can better meet the diversified requirements of the services and offer great extensibility and programmability based on the scalable segment (SID) list of SRv6 header (SRH). In this paper, we define a new control plane function named route control function (RCF) to compute the traffic routes and generate the RIDs, and propose a solution for establishing the traffic routes per application using the RCF. As a way to implement the solution, we also present use cases in which the (R)ANs and SMF obtain the RIDs, the PCF utilizes the RIDs to generate the URSP rules or the PCC rules, and the RIDs are applied during data transfer. The proposed solution can evolve to support the dynamic service (and/or network) programming and slicing at the application level.
