Abstract:
1. A method for wireless communication comprising: establishing one or more radio link flows between a mobile device and an Internet Protocol (IP) access gateway of a radio access network, wherein each radio link flow has a different quality of service (QoS) reservation; transmitting on the one or more radio link flows having different QoS reservations one or more echo request messages to an echo service hosted by the access gateway; receiving on the one or more radio link flows having different QoS reservations one or more echo response messages from the echo service, wherein the echo response messages correspond to the echo request messages; calculating the round trip time (RTT) for the transmitted and received echo messages for each radio link flow having different QoS reservations; and modifying QoS reservations of the one or more radio link flows based on the computed RTT for the one or more radio link flows having different QoS reservations to reduce latency of transmissions on one or more radio link flows.
