Abstract: The present disclosure provides a system (210) and a method for providing a security mechanism to a User Equipment (UE) (204) in a coreless radio access network (RAN). The system (210) receives a registration request from a UE (204), where the registration request includes user subscription data. The system (210) determines if the user subscription data is available within a mobile radio unit for a specific geographic area. Based on a positive determination, the system (210) provides a security mechanism to the UE (204). Based on a negative determination, the system (210) may send a data acquisition request to at least one data source. The system (210) may receive data associated with the specific geographic area from the at least one data source, and provide the security mechanism to the UE (204) based on the received data.

Abstract: The present disclosure provides a system and a method for enabling a coreless network architecture by proposing a Radio Access Network (RAN) node for providing network coverage and services to User Equipment (UE) while not being connected or dependent on the core network. In an embodiment, the RAN node may be a mobile RAN node that forms a part of a fleet to provide network coverage and services to UEs at any geolocation as per the requirement. The disclosure also proposes mechanisms for the mobile RAN nodes to communicate amongst each other and also intermittently with the core network and data network (ISP) when available.
