Traffic Flow Template (LTE)

In LTE, Traffic Flow Templates (TFTs) are set up both on the mobile device and at the Packet Gateway (P-GW) to decide if a specific traffic stream should pass through a particular EPS bearer. Consequently, when a Dedicated EPS bearer is created, an uplink TFT is installed on the handset and a downlink TFT is installed at the P-GW. The TFT includes packet filters based on possible packet characteristics such as IP address and port.
