System and method for securely hosting multiple network operators in a shared spectrum access system on a single virtual base station environment

A non-transitory computer readable memory encoded with instructions which, when executed by one or more processors, cause the one or more processors to implement a system for hosting a plurality of mobile network operators on a virtual wireless base station, the system comprising:

• a plurality of baseband processors, each of the plurality of baseband processors configured to communicate with a corresponding mobile network operator within the plurality of mobile network operators;
• a fronthaul network interface configured to be coupled to one or more remote units and to each of the plurality of baseband processors, the fronthaul interface having a CPRI (Common Public Radio Interface) transport layer, a first DMA buffer coupled to a first one of the plurality of baseband processors and the CPRI transport layer, a second DMA buffer coupled to a second one of the plurality of baseband processors and the CPRI transport layer, and a mapping module coupled to a supervisor module, the first DMA buffer, the second DMA buffer, and the CPRI transport layer,
• wherein the mapping module is configured to map a first plurality of data samples from the first baseband processor to the first DMA buffer corresponding to a first portion of a CPRI transport block in the CPRI transport layer;
• and a second plurality data samples from the second baseband processor to the second DMA buffer corresponding to a second portion of the CPRI transport block in the CPRI transport layer;
• and
• wherein the supervisor module is coupled to the plurality of baseband processors and the fronthaul network interface.
