Transport congestion control optimization based on network context

A network device, comprising:

• at least one communication interface to:
• transmit first data to a user equipment (UE) via a Long-Term Evolution (LTE) Radio Access Network (RAN) using Transmission Control Protocol (TCP) congestion control parameters, wherein the TCP congestion control parameters comprise a segment size parameter (segsize) associated with a TCP congestion window (CWND) and a slow start threshold parameter (ssthresh) associated with a slow start phase of TCP congestion control, and
• receive a notification message indicating that the UE has moved from the LTE RAN to a Next Generation RAN;
• and
• a processor, or logic, that increases, responsive to receipt of the notification message indicating that the UE has moved from the LTE RAN to the Next Generation RAN, a value of the segsize while simultaneously decreasing the ssthresh such that the CWND increments at a faster rate over a shorter period of time;
• wherein the at least one communication interface further transmits second data to the UE via the Next Generation RAN using the increased segsize and the decreased ssthresh of the TCP congestion control parameters.

A non-transitory storage medium storing instructions executable by a network device with one or more processors, wherein execution of the instructions causes the network device to:

• transmit first data to a user equipment (UE) via a Long-Term Evolution (LTE) Radio Access Network (RAN) using Transmission Control Protocol (TCP) congestion control parameters, wherein the TCP congestion control parameters comprise a segment size parameter (segsize) associated with a TCP congestion window (CWND) and a slow start threshold parameter (ssthresh) associated with a slow start phase of TCP congestion control;
• receive a notification message indicating that the UE has moved from the LTE RAN to a Next Generation RAN;
• increase, responsive to receipt of the notification message indicating that the UE has moved from the LTE RAN to the Next Generation RAN, a value of the segsize while simultaneously decreasing the ssthresh such that the CWND increments at a faster rate over a shorter period of time;
• and
• transmit second data to the UE via the Next Generation RAN using the increased segsize and the decreased ssthresh of the TCP congestion control parameters.

A method, comprising:

• and
• transmitting, from the network device, second data to the UE via the LTE RAN using the increased segsize and the decreased ssthresh of the TCP congestion control parameters.
