Network exposure function for a service oriented network

A system for cellular communications for use with a multi-core network having a plurality of core slices, the system comprising:

• one or more processors;
• a memory device storing a set of instructions that when executed by the one or more processors, causes the one or more processors to:
• receive, at a network exposure layer, a plurality of requests for access to the multi-core network through application programming interfaces (APIs) of respective plurality of tenants, the plurality of requests comprising a first request from a first API of a first tenant;
• provide data transfers between the first tenant and the first core slice in response to determining that the first core slice is associated with the first tenant and the first tenant being authenticated using a first core slice from the plurality of core slices that is associated with the first tenant, in response to the first tenant being determined to be authenticated, wherein the network exposure layer comprises:
• a common API framework (CAPIF) configured to authenticate the first API;
• and
• a network exposure function (NEF) configured to communicate between the first API and the multi-core network, in response to the first API being authenticated by the CAPIF.

A method for cellular communications between tenants and a multi-core system, the method comprising:

• receive, at a network exposure layer, a plurality of requests for bandwidth from an application programming interface (API) of the tenants, the plurality of requests comprising a first request from a first API of a first tenant;
• determine whether the first tenant is authenticated using information from the first request;
• in response to the first tenant being determined to be authenticated, determine a first core slice that is associated with the first tenant, the first core slice being one of a plurality of core slices in the multi-core network;
• and
• provide data transfers between the first tenant and the first core slice in response to determining that the first core slice is associated with the first tenant and the first tenant being authenticated, wherein the network exposure layer comprises:
• a common API framework (CAPIF) configured to authenticate the first API;
• and
• a network exposure function (NEF) configured to communicate between the first API and the multi-core network, in response to the first API being authenticated by the CAPIF.
