Abstract

A method includes generating a test call from a user device to a public safety access point, wherein the test call is generated on a schedule, wherein the test call is configured to test call parameters, and wherein the test call parameters comprise a planned base station site and a planned base station sector, acquiring call detail data associated with the test call, in which the call detail data includes an identification of an actual base station site and an actual base station sector used for the test call and the public safety access point receiving the test call, and wherein the actual base station site collects the call detail data, determining whether the call detail data matches the test call parameters, and generating a pass or fail determination based on the determining step.

Claims (52)

1 . An emergency test call management system comprising:

a processing system including a processor; and

a memory that stores executable instructions that, when executed by the processing system facilitate performance of operations, the operations comprising:

receiving, through a user interface and from a testing device, test parameters for a test call configured for testing connectivity between a public safety access point and a cellular network, wherein the test parameters include: a parameter pertaining to a radio frequency protocol, a parameter pertaining to distance, one of a plurality of sectors to be tested, and one of a frequency band for the test call, an emergency class of service for the test call, or both the frequency band for the test call and the emergency class of service for the test call;

receiving test data from a base station at a conclusion of the test call;

evaluating the test data based on the test parameters; and

generating a report based on the evaluating the test data,

wherein the testing device is associated with a vehicle,

wherein the test call is initiated remotely from the vehicle upon a command of a validation test server, and

wherein the test call is initiated at a location that is based on a relative position of a cell site and the one of the plurality of sectors to be tested.

2 . The emergency test call management system of claim 1 , wherein the test parameters include a specified base station and a specified cell sector within the base station, and wherein the evaluating the test data compares an actual base station and an actual cell sector that carried the test call to the specified base station and the specified cell sector.

3 . The emergency test call management system of claim 1 , wherein the test parameters further include a routing path to the public safety access point.

4 . The emergency test call management system of claim 1 , wherein the operations further include:

causing the test call to be initiated.

5 . The emergency test call management system of claim 1 , wherein the operations further include:

retrieving location data for the test call and confirming that the location data was reported to the public safety access point.

6 . The emergency test call management system of claim 1 , wherein the operations further include providing driving instructions for the vehicle.

7 . A method comprising:

acquiring, by a processing system including a processor, call detail data associated with a test call from a user device to a public safety access point, in which the call detail data includes an identification of an actual base station site and an actual base station sector used for the test call, and the public safety access point receiving the test call;

determining, by the processing system, whether the call detail data matches test call parameters received from a testing device, wherein the test call parameters identify: a parameter pertaining to a radio frequency protocol, a parameter pertaining to distance, a planned base station site, a planned base station sector, and one of a frequency band for the test call, an emergency class of service for the test call or both the frequency band for the test call and the emergency class of service for the test call; and

generating, by the processing system, a pass or fail determination based on the determining whether the call detail data matches the test call parameters,

wherein the testing device is associated with a vehicle,

wherein the test call is initiated remotely from the vehicle upon a command of a validation test server, and

wherein the test call is initiated at a location that is based on a relative position of a cell site and the planned base station sector.

8 . The method of claim 7 , further comprising:

determining, by the processing system, whether the location of the test call was reported to the public safety access point.

9 . The method of claim 8 , wherein the location of the test call was determined within a predetermined range.

10 . The method of claim 8 , wherein the pass or fail determination is sent via one of a text message or email.

11 . A non-transitory, machine readable medium comprising executable instructions, which, when executed on a processing system including a processor, facilitate performance of operations, the operations comprising:

collecting call detail data associated with a test call from a user device to a public safety access point, in which the call detail data includes an identification of an actual base station site and an actual base station sector used for the test call and the public safety access point receiving the test call, and wherein the actual base station site collects the call detail data;

determining whether the call detail data matches test call parameters identifying: a parameter pertaining to a radio frequency protocol, a parameter pertaining to distance, a planned base station site, a planned base station sector, and one of a frequency band for the test call, an emergency class of service for the test call or both the frequency band for the test call and the emergency class of service for the test call; and

generating a pass or fail determination based on the determining whether the call detail data matches the test call parameters,

wherein the test call parameters are received from a testing device,

wherein the testing device is associated with a vehicle,

wherein the test call is initiated remotely from the vehicle upon a command of a validation test server, and

wherein the test call is initiated at a location that is based on a relative position of a cell site and the planned base station sector.

12 . The non-transitory, machine readable medium of claim 11 , wherein the operations further comprise:

receiving, from a user interface, scheduling data and the test call parameters relating to the test call.

13 . The non-transitory, machine readable medium of claim 11 , wherein the operations further comprise:

generating a user interface wherein the user interface includes a scheduling component, a call detail report component, and a validation component.

14 . The non-transitory, machine readable medium of claim 13 , wherein the validation component is color-coded to indicate the pass or fail determination visually.

15 . The non-transitory, machine readable medium of claim 11 , wherein the operations further comprise:

scheduling a plurality of test calls; and

receiving, from a user interface, scheduling data for the plurality of test calls, test call parameters relating to each of the plurality of test calls.

16 . The non-transitory, machine readable medium of claim 15 , wherein the operations further comprise:

generating validation results and transmitting the validation results to the user interface.

17 . The non-transitory, machine readable medium of claim 16 , wherein the pass or fail determination is conveyed via a text message or an email communication.

18 . The non-transitory, machine readable medium of claim 16 , wherein the operations further comprise:

generating a roll-up report containing the validation results for the plurality of test calls.

19 . The non-transitory, machine readable medium of claim 16 , wherein the operations further comprise:

initiating test support for each of the plurality of test calls.

20 . The non-transitory, machine readable medium of claim 11 , wherein the pass or fail determination is color-coded to indicate the pass or fail determination visually.
