Study on UDICOM
Abstract of document: SA WG2 has defined in TS 23.501 Release 15 an architecture for 5GS and EPS interworking based on a number of combined functions, including an HSS+UDM node which precludes a multivendor approach for UDM and HSS when there may be, in fact, scenarios in which introducing only UDM/UDR is an effective way to introduce 5GS. This Technical Report has investigated different solutions for separating HSS and UDM, where EPS subscriber data and 5GS subscriber data coexist in data storages that can be common or separate. It must be noticed that multiple different deployments of 3GPP networks exist, making difficult the selection of one single solution. Depending on the evolution of the network operator, i.e. from 2G or 3G or 4G onwards, the introduction of one or another solution may be not feasible or cost effective. As anticipated when the study was sent for information, conclusions point into different alternatives to resolve the effective separation of UDM and HSS when in
