Abstract: Techniques are provided to communicate the serving Radio Access Network (RAN) element information to the packet core network to enable operators to provide differential treatment for fifth generation (5G) subscribers. The techniques presented herein fill these gaps and help drive faster adoption of Dual Connectivity New Radio (DCNR) subscribers by service operator to offer customized policy and quota management to address different business requirements in the 5G Non-Stand Alone (NSA) architecture.

Abstract: In one example, an indication that a user equipment participating in a Packet Data Network (PDN) session hosted by a Serving Gateway (SGW) and a PDN Gateway (PGW) is transitioning from a first Mobility Management Entity (MME) to a second MME is obtained. An indication that the SGW is co-located with the PGW and an identification of the SGW are obtained. Based on the indication that the SGW is co-located with the PGW and the identification of the SGW, it is determined that the SGW is reachable from the second MME. In response to determining that the SGW is reachable from the second MME, the SGW is selected to host the PDN session after the user equipment transitions from the first MME to the second MME.

Abstract: In one example, a User Plane Function (UPF) in a Visited Public Land Mobile Network (V-PLMN) that includes a first network and a second network obtains network traffic from user equipment via the first network. The UPF provides the network traffic obtained via the first network to a data network with an Internet Protocol (IP) address allocated to the network traffic obtained from the user equipment. In response to a handover of the user equipment from the first network to the second network, the UPF obtains the network traffic from the user equipment via the second network. The UPF provides the network traffic obtained via the second network to the data network with the IP address.

Abstract: When a packet data session is established for a user equipment (UE), a comparative assessment of load information factors from different sets of load information factors associated with a plurality of user plane function (UPF) instances may be performed. Each set of load information factors of a UPF instance may include predicted load information factors indicative of a predicted load at the UPF instance. A UPF instance may be selected for the packet data session of the UE based on the comparative assessment. The comparative assessment may additionally consider a predicted load contribution of the packet data session to be established for the UE. A data analytics function may utilize a model (e.g. a multiple linear regression model) to calculate predicted load contribution factors, where the model is derived based on historical usage data from previous sessions of one or more UEs, for example, data from charging data records (CDRs).
