Abstract
A Long Term Evolution (LTE) Serving Gateway (S-GW) to indicate mode transitions of a wireless communication device comprises a communication transceiver and a processing system. The communication transceiver is configured to establish a default bearer between the LTE S-GW and an LTE Packet Data Network Gateway (P-GW) for the wireless communication device, establish a bearer channel between an LTE access node and the LTE S-GW, and exchange data over the bearer channel responsive to the wireless communication device entering an active mode. The processing system is configured to release the bearer channel between the LTE access node and the LTE S-GW responsive to the wireless communication device entering an idle mode, generate mode transition records indicating idle-to-active mode transitions and indicating active-to-idle mode transitions of the wireless communication device, and direct the communication transceiver to transfer the mode transition records.
