Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to determine the number of people at a location. An example apparatus includes a configuration changer to change a configuration setting of the base station to cause mobile devices to register with the base station, a registration manager to respond to registration requests received from the mobile devices after the configuration setting is changed by storing device identification information for the corresponding mobile devices, and a counter controller to identify a number of the mobile devices at a location of the base station based on the stored device identification information.

Abstract: Example methods, apparatus, and articles of manufacture are disclosed to determine a telecommunications account status. An example apparatus includes a data collector associated with a measurement entity, the data collector including a processor and a memory storing instructions to be executed by the processor to: send a credit transfer request to a crediting system associated with a mobile communications service provider, the request associated with a device identifier corresponding to a mobile communication device; receive a response associated with the credit transfer request, the response including an error message; and determine an account status of the device identifier based on the error message.

Abstract: Example methods, apparatus, and articles of manufacture are disclosed to determine a telecommunications account status. An example method includes initiating a credit transfer request via the device identifier, determining, via a processor, whether an account associated with the device identifier comprises a prepaid type in response to receiving an indication of credit transfer success, and determining whether the account associated with the device identifier comprises a non-prepaid account type in response to receiving an indication of credit transfer failure.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to determine the number of people at a location. An example method includes collecting media identification information corresponding to media presented at a location, changing an identifier of a base station local to the location to cause mobile devices located at the location to attempt to register with the base station, responding to a received request to register a mobile device with the base station by storing device identification information for the corresponding mobile device at the base station, determining a number of mobile devices located at the location based on the stored device identification information, and identifying a number of persons exposed to the media based on the mobile devices located at the location.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to determine the number of people in an area. An example method includes collecting media identification information corresponding to media presented at a location, responding to a received request to register a mobile device with a base station by storing device identification information for the mobile device at the base station, timestamping the device identification information, determining a number of mobile devices located in an area based on the stored device identification information, and identifying a number of persons exposed to the media based on the media identification information and the device identification information.
