Claim:
1. A method of operating a Long Term Evolution (LTE) Serving Gateway (S-GW) to indicate mode transitions of a wireless communication device, the method comprising: establishing a default bearer between the LTE S-GW and an LTE Packet Data Network Gateway (P-GW) for the wireless communication device; establishing a bearer channel between an LTE access node and the LTE S-GW and exchanging data over the bearer channel responsive to the wireless communication device entering an active mode; releasing the bearer channel between the LTE access node and the LTE S-GW responsive to the wireless communication device entering an idle mode; generating mode transition records indicating idle-to-active mode transitions and indicating active-to-idle mode transitions of the wireless communication device; and transferring the mode transition records for delivery to an accounting data processing system, wherein the accounting data processing system is configured to process the mode transition records to determine a number of mode transitions associated with the wireless communication device over a time period and compare the number of mode transitions over the time period to a threshold value.
