Method and apparatus for managing transmission of TCP data segments

A method for managing transmission of at least one data segment over an interface of a wireless communication network, the method comprising:

• receiving a data segment for transmission over the interface;
• comparing, in transmission management logic, a sequence number of the received data segment with at least one pending sequence number of at least one previously received data segment;
• discarding the received data segment in response to the sequence number of the received data segment matching the at least one pending sequence number;
• adding the sequence number of the received data segment to the at least one pending sequence number in response to the sequence number of the received data segment not matching the at least one pending sequence number;
• and
• transmitting the received data segment over the interface,
• wherein a plurality of pending sequence numbers is stored as a list of pending sequence numbers, and the sequence number of the data segment to be transmitted is considered as matching the at least one pending sequence number if a same sequence number is present within the list of pending sequence numbers, an the sequence number of an acknowledged data segment is removed from the list of pending sequence numbers in response to receipt of an acknowledgement that the acknowledged data segment has been successfully received by a user equipment of the wireless communication network.

A non-transitory computer readable medium comprising instructions for managing transmission of at least one data segment over an interface, the instructions for:

• receiving a data segment for transmission over the interface;
• comparing a sequence number of the received data segment with at least one pending sequence number of at least one previously received data segment;
• discarding the received data segment in response to the sequence number of the received data segment matching the at least one pending sequence number;
• adding the sequence number of the received data segment to the at least one pending sequence number in response to the sequence number of the received data segment not matching the at least one pending sequence number;
• and
• transmitting the received data segment over the interface,
• wherein a plurality of pending sequence numbers is stored as a list of pending sequence numbers, and the sequence number of the data segment to be transmitted is considered as matching the at least one pending sequence number if a same sequence number is present within the list of pending sequence numbers, an the sequence number of an acknowledged data segment is removed from the list of pending sequence numbers in response to receipt of an acknowledgement that the acknowledged data segment has been successfully received by a user equipment of the wireless communication network.
