A solution is presented for a cost-effective way of providing redundancy for a user equipment (UE) session while utilizing resources of an active and a standby user plane function (UPF). UPFs are used efficiently by creating redundancy for each other with support from a session management function (SMF). The solution further enhances N:M redundancy. This model is fully applicable for edge UPF deployments where resources are limited. The solution can be used for providing ultra-reliable low latency communication services, enterprise services based applications supported using 5G core in which there is higher service level agreement (SLA) bearing and transport path diversity.
