Method and system for providing a fallback solution in a multi-tenant communication system

A method for providing a fallback solution in a multi-tenant communication system, the method comprising:

• communicating between a first RF site at a first radio-access network (RAN) and a second RF site at a second RAN through a first link through a cloud-based call-processing service;
• determining that a second link through the cloud-based call-processing service has failed, wherein the second link established communication between a third RF site on the first RAN and a fourth RF site on the second RAN;
• implementing a fallback mode of communication for the third RF site, in response to the second link going down, wherein the fallback mode of communication:
• drops communication between the third RF site and the cloud-based call-processing service;
• establishes communication between the third RF site and a local call-processing service;
• allows communication between the third RF site and other RF sites existing only at the first RAN through the local call-processing service;
• allows the first RF site to communicate through the cloud-based call-processing service.

A radio-access network (RAN) having a first RF site in communication with a second RF site at a second RAN through a first link established through a cloud-based call-processing service, the radio-access network comprising:

• a fallback core configured to:
• determine that a second link through the cloud-based call-processing service has failed, wherein the second link established communication between a third RF site on the first RAN and a fourth RF site on the second RAN;
• implement a fallback mode of communication for the first RAN, in response to the second link going down, wherein the fallback mode of communication allows communication between RF sites existing only at the first communication system;
• and
• in response to the implementation of the fallback mode of communication, drop the first link through the cloud-based call-processing service.

A radio-access network (RAN) supporting communication between a first RF site at the RAN and a second RF site at a second RAN through a first link existing through a cloud-based call-processing service, the RAN comprising:

• a fallback core configured to:
• determine that a second link through the cloud-based call-processing service has failed, wherein the second link established communication between a third RF site at the RAN and a fourth RF site on the second RAN;
• implement a fallback mode of communication for the third RF site, in response to the second link going down, wherein the fallback mode of communication:
• drops communication between the third RF site and the cloud-based call-processing service;
• establishes communication between the third RF site and a local call-processing service;
• allows communication between the third RF site and other RF sites existing only at the first RAN through the local call-processing service;
• allows the first RF site to communicate through the cloud-based call-processing service.
