Patent ID: 11240096

Abstract:
The present application relates to a mobile core network (MCN) supporting end-to-end (E2E) network slicing, which comprises a controlling entity (CA_NF), one or more network function (NF) entities extended with functionalities (CA-NFExt), a network management entity (OSS) extended with functionalities (CA_OSSExt), and a coordination entity (CA_CF). The CA_NF communicates with the CA_OSSExt through the CA_CF using interfaces (If-CA_MP and If-CAC_OSS), and with the CA-NFExts using a respective interface (If-CA_NF) and/or other NFs interfaces. Based on information received from the OSS and the NF entities, the CA_NF generates a context with a certain type, sends, based on the generated context, context-related information towards entities impacted by the generated context amongst the NF entities and the OSS, and blocks, for a period of time, a transmission of any generated context towards the NF entities upon receiving, from the OSS, a notification message once the OSS decides to enforce a change.
