Abstract
Methods and apparatus for use in reducing signal latency in a mobile network with use of localized Unified Data Management (UDM) entities are described. For example, the technique may employ a plurality of localized UDMs, where each localized UDM is associated with a unique location area. A localized UDM provides for storage of, in a localized Unified Data Repository (UDR), subscriber profile data associated with a subscriber of user equipment (UE). The subscriber profile data stored in the localized UDR may be a replica or copy of at least a subset of subscriber profile data for the subscriber stored in a UDR of a “centralized” UDM. Query access to the localized UDR may be provided for network functions (NFs) or subscriber/UEs. The replica or copy of subscriber profile data may be stored in the localized UDR for those subscribers having use in the location area.
