Patent: Inter-RAN Spectrum Optimizer

The Inter-Radio Access Network Spectrum Optimizer is a concept in which Radio Frequency resources – a finite commodity in very high demand – are instantaneously maximized based directly on the collective supply and demand of aggregate (and competing) mobile networks in any given location.

The cornerstone of the platform is the Session Manager which consists of a Host in the network core, and numerous Controllers at the network edge. The role of the Controller is to evaluate spectrum supply and demand in real time, and assign resources accordingly. The platform can accommodate variations on this basic operational concept based on predefined business, engineering and operational rules. Finally, the Controllers deliver Charging Data Records (CDR) to a clearing and settling environment at the Host for reconciliation and delivery to the respective billing systems of the participating Mobile Network Operators (MNOs).

From a business model perspective, there is a compelling precedent for this type of relationship where competitors pool their resources to improve their collective service performance. In the early 1980s, Automatic Teller Machines (ATM) began to appear in Canada. The hardware was expensive as were the recurring costs for communications facilities back to the bank’s data center. In order for the general public to adopt this new approach to banking, the belief was that ATM penetration had to be much higher than any one financial institution could single handedly deploy. In response, Interac was formed as a cooperative network to support cross-bank ATM usage by member financial institutions. To this day, this cooperative works very well and has proven to be the foundation for other advances not directly related to the ATM network.

A more germane precedent is the Internet itself. As a ‘network of networks’, infrastructure supporting the Internet is incalculably enormous and complex, and by its very nature, openly shared. The end user’s relationship with the Internet is largely defined by his/her relationship with their ISP, even though the ‘invisible’ networks that make up the Internet are an essential part of the Internet experience. This cooperative approach to resource sharing among numerous network operators may prove prescient for Radio Access Network pooling as is proposed here.
