Methods and Systems for Performing Dynamic Spectrum Arbitrage Based on eNodeB Transition States

A dynamic spectrum controller (DSC), comprising:

• a memory;
• a processor coupled to the memory, wherein the processor is configured with processor-executable instructions to perform operations comprising:
• monitoring a congestion state of an eNodeB in a first telecommunication network by receiving congestion state information from the eNodeB, the congestion state information identifying the eNodeB as being in one of a normal congestion state, a minor congestion state, a major congestion state, and a critical congestion state;
• detecting that the congestion state of the eNodeB transitioned from the normal congestion state to the critical congestion state based on the monitoring;
• and
• controlling the use of the eNodeB in response to detecting that the congestion state of the eNodeB transitioned from the normal congestion state to the critical congestion state by:
• communicating with a dynamic spectrum policy controller (DPC) to cause the DPC to instruct a second DSC in a second telecommunication network to restrict further handovers to the first telecommunication network, identify desired closed subscriber group identifiers (CSG ids) for which handovers should be restricted, and instruct a home Mobility Management Entity (MME) component of the second telecommunication network to disable roaming for wireless devices associated with the CSG ids in response to determining that the congestion state of the eNodeB transitioned from the normal congestion state to the major congestion state;
• determining whether there is a non-congested target eNodeB in the first telecommunication network in response to determining that the congestion state of the eNodeB transitioned from the normal congestion state to the critical congestion state;
• initiating a S1-based handover procedure for a wireless device to the target eNodeB in response to determining that the target eNodeB is non-congested;
• instructing the eNodeB to initiate a quality of service (QoS) degradation procedure for all wireless devices of the second telecommunication network attached to the eNodeB in response to determining that there is no non-congested target eNodeB in the first telecommunication network;
• determining whether there are any non-congested eNodeBs within a vicinity of the first telecommunication network in response to determining that there is no non-congested target eNodeB in the first telecommunication network;
• instructing a home subscriber server (HSS) to perform a detach procedure in response to determining that there are no non-congested eNodeBs within the vicinity of the first telecommunication network;
• and
• instructing the HSS to perform the detach procedure in response to determining that the S1-based handover procedure failed.
