Abstract
TCP sessions passing through a network, such as a wireless network, may be optimized based on conditions corresponding to the radio interface of the wireless network. In one implementation, a method may include monitoring, by a base station, performance parameters relating to a radio access network (RAN); determining, based on the performance parameters, one or more protocol data units (PDUs) to retransmit; determining one or more Transmission Control Protocol (TCP) sessions and packet sequence numbers corresponding to the one or more PDUs; and transmitting, to a network device, an indication to retransmit packets corresponding to the one or more TCP sessions and packet sequence numbers.
Claims20
A method comprising:
- monitoring, by a base station, performance parameters relating to a radio access network (RAN);
- determining, by the base station and based on the performance parameters, one or more protocol data units (PDUs) to retransmit;
- determining, by the base station, one or more Transmission Control Protocol (TCP) sessions and packet sequence numbers corresponding to the one or more PDUs;
- determining, by the base station and based on the performance parameters, to implement early retransmission of the PDUs;
- implementing the early retransmission of the PDUs by:
- prior to the base station detecting a failure of transmitted packets, and prior to receiving, from a first end device and intended for a second end device, a request-for the second end device to retransmit packets corresponding to the one or more TCP sessions and packet sequences,
- transmitting, by the base station and to a network device, an indication to retransmit the packets corresponding to the one or more TCP sessions and packet sequence numbers;
- and
- receiving, by the base station, from the network device, and in response to transmitting the indication, the packets corresponding to the indication, the packets having a higher Quality of Service Class Identifier (QCI) value than a QCI value with which the transmitted packets were originally transmitted.

A network device comprising:
- a non-transitory memory device storing a plurality of processor-executable instructions;
- and
- a processor configured to execute the processor-executable instructions, wherein executing the processor-executable instructions causes the processor to:
- receive packets from a server device as part of a Transmission Control Protocol (TCP) session;
- cache the received packets in a cache;
- transmit the received packets towards a destination device;
- prior to a base station detecting a failure of the transmitted packets, and prior to receiving a request, initiated by the destination device and intended for the server device, to retransmit packets corresponding to the TOP session, receive, from a base station associated with a wireless network, an instruction to retransmit, to the destination device, one or more of the transmitted packets, the instruction being initiated by the base station;
- and
- retransmit, in response to the instruction, the one or more of the received packets, towards the destination device, the one or more received packets having a higher Quality of Service Class Identifier (QCI) value than a QCI value with which the transmitted packet was originally transmitted.

A system comprising:
- a base station including processing circuitry to:
- monitor performance parameters relating to a radio access network (RAN) used to wirelessly connect to user equipment (UE),
- determine, based on the performance parameters, one or more protocol data units (PDUs) to retransmit, determine a packet corresponding to the one or more PDUs,
- determine, by the base station and based on the performance parameters, to implement early retransmission of the one or more PDUs, and
- implement the early retransmission of the one or more PDUs by:
- prior to detecting a failure of the base station to transmit the packet, and prior to receiving, from the UE and intended for a server device, a request for the server device to retransmit the packet corresponding to the one or more PDUs,
- transmit an indication to retransmit the packet;
- and
- a network device including processing circuitry to:
- receive, from the base station;
- the indication to retransmit the packet, read the packet from a cache maintained by the network device, and
- transmit, in response to the indication, the packet towards the UE via the base station, the packet having a higher Quality of Service Class Identifier (QCI) value than a QCI value with which the transmitted packet was originally transmitted.
