Method and system for measuring availability in a communications network
View Patent ↗In a system for availability metrics for customer premises equipment (CPE), CPE includes a non-volatile memory and a timer. Service availability interruption events and time stamps associated with the events are recorded in the non-volatile memory and transmitted to a computing device, which calculates availability metrics based on the interruption events and time stamps from the non-volatile memory of the CPE.
1. A system for determining availability metrics for customer premises equipment (CPE), the system comprising:
a processor; and
a non-transitory computer readable medium with computer executable instructions stored thereon, which, when executed by the processor, perform the following method:
receiving data from a plurality of CPEs; and
calculating a service availability metric using the data,
wherein the data includes service availability information and a time stamp associated with a service availability status, the service availability information including data indicating a loss of power to a CPE of the plurality of CPEs and data indicating that a communication wire was removed from a CPE of the plurality of CPEs,
wherein calculating the service availability metric includes parsing the data so that times during which service was not made available at the CPE due to a loss of power and removal of a communication wire are not included in the service availability metric.
2. The system of claim 1 , wherein the data indicating the loss of power to the CPE is stored in a non-volatile memory of the CPE after power is removed from the CPE.
3. The system of claim 1 , wherein the service availability information includes data indicating that a reset operation was performed by a CPE of the plurality of CPEs.
4. The system of claim 1 , wherein the plurality of CPEs communicate wirelessly with base stations, and the service availability information includes data indicating that signal loss occurred at a CPE of the plurality of CPEs by moving out of range from a base station.
5. The system of claim 4 , wherein the information indicating that the CPE lost communication includes accelerometer information.
6. The system of claim 1 , wherein the service availability information is information recorded by the plurality of CPEs on a periodic basis.
7. The system of claim 1 , wherein the service availability information includes an identity of network equipment which is responsible for network services not being made available to the CPE.
8. The system of claim 1 , wherein the service availability metric is a percentage of time that the service is available.
9. A method for calculating a communications network availability metric, the method comprising:
receiving data from a plurality of customer premises equipment (CPEs); and
calculating a service availability metric using the data,
wherein the data includes service availability information indicating a lack of service due to a condition not associated with an equipment failure, and a time stamp associated with the service availability status, the service availability information including data indicating a loss of power to a CPE of the plurality of CPEs and data indicating that a communication wire was removed from a CPE of the plurality of CPEs,
wherein calculating the service availability metric includes parsing the data so that times during which service was not available at the CPE due to a loss of power and removal of a communication wire are not included in the service availability metric.
10. The method of claim 9 , wherein the customer premises condition is the CPE moving out of service range.
11. The method of claim 9 , wherein the service availability metric is a percentage of time that the service is available.
