As we know, 5G is the 5th generation mobile network, was designed to co-exists with previous generations (viz., 4G LTE etc.,) and deliver highest data speeds, ultra-low latency, more reliability, massive network capacity, increased availability, more uniform user experience (Quality of Experience [QoE]) to more users. But there are scenarios where-in Quality of Experience (QoE) is not maintained viz., when UE with multiple slices initially attach to 4G and roam to 5G, or when UE is in compromised (viz., rogue base station) coverage area, etc., There are techniques which provide methods to use UUT for mapping UE to network slice. But using only UUT for network slice selection will not be optimal for advanced slice mapping and better gateway selection. The technique presented herein propose method to select the right slice and the right gateway (PGW-C + SMF) node based on the slice subscriptions of 5G UE (or based on user preference of the slice), and UUT values of UE (in-turn priority) and/or Network Capabilities (NC).
