Embodiment 1

[0076] Such as figure 1 As shown, the first embodiment of the present invention realizes the method for TCP data packet retransmission including:

[0077] Step 100, the base station stores the received TCP data message from the core network in the cache area, and adds the received TCP data message to the normal priority sending data queue;

[0078] Step 101. After receiving the TCP response message from the terminal, the base station determines whether to retransmit the retransmitted TCP data message in the buffer area to the terminal;

[0079] Step 102, after the base station determines that the TCP data message corresponding to the message confirmation number in the TCP response message in the buffer area needs to be retransmitted to the terminal, the retransmitted The TCP data message is added to the high-priority sending data queue;

[0080] Step 103, when the base station determines that TCP data packets need to be sent, send the TCP data packets in the queue according ...

Abstract

An embodiment of the invention provides a method and equipment for retransmitting TCP (transmission control protocol) data messages and aims to solve the problem that a method for retransmitting TCP data messages through a core network is not high in retransmission timeliness rate in the prior art. The method comprises steps as follows: a base station stores the received TCP data messages from the core network in a cache zone and adds the TCP data messages to a normal priority sending data queue; the base station judges whether to retransmit the TCP data messages which can be retransmitted and are stored in the cache zone to a terminal or not after receiving TCP response messages from the terminal; the base station adds the TCP data messages which can be retransmitted to a high priority sending data queue after determining that retransmission is required; the base station sends the TCP data messages according to the priority sequence of queues when determining that the TCP data messages are required to the retransmitted. With the adoption of the method, the base station retransmits the TCP data messages which can be retransmitted to the terminal according to the priority sequence, and the retransmission timeliness rate is increased.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and equipment for realizing TCP data message retransmission. Background technique [0002] At present, after the base station receives the IP (Internet Protocol, the protocol for interconnection between networks) data message from the core network, it directly adds it to the data transmission queue of the base station, and then sequentially sends the IP data message in the data queue and sent to the corresponding terminal, wherein the network datagram received by the base station from the core network may be a TCP (Transmission Control Protocol, transmission control protocol) datagram. After receiving the TCP response message from the terminal through the air interface, the base station sends the TCP response message to the core network, so that the core network determines whether to retransmit the corresponding TCP data message according to the received T...
