Problems solved by technology

[0002] At present, the TCP protocol uses mechanisms such as fast retransmission to ensure the quality of service. In the case of terminal cellular access, because the TCP side cannot know the transmission status of the wireless side, there may be cases where the wireless side has successfully transmitted or is still transmitting, but the server within a certain period of time Cases where packets are not received

Embodiment 1

[0035] An embodiment of the present invention provides a method for sending information, which is applied to wireless network devices, such as figure 1 shown, including:

[0036] Step 101: receiving a TCP message retransmission request from the terminal;

[0037] Step 102: Based on the TCP message retransmission request, retransmit the sent data message corresponding to the terminal; or retransmit the data to be sent corresponding to the terminal; or retransmit the corresponding data message of the terminal; The corresponding data message is assembled, or disassembled, or repackaged before being sent; wherein, the data message includes the sent data message and / or the data to be sent.

[0038] Here, it should be noted that the receiving the TCP message retransmission request from the terminal side may be that the terminal sends the retransmission request to the wireless network device when it detects that its TCP layer needs to retransmit the message.

[0039] The TCP messag...

Embodiment 2

[0068] An embodiment of the present invention provides a method for sending information, which is applied to a terminal, such as figure 2 shown, including:

[0069] Step 201: the terminal detects that the TCP layer needs to retransmit the message;

[0070] Step 202: Send a TCP message retransmission request to the wireless network device.

[0071] Here, it should be noted that the receiving the TCP message retransmission request from the terminal side may be that the terminal sends the retransmission request to the wireless network device when the terminal detects that its TCP layer needs to retransmit the message.

[0072] Specifically, it is detected that the TCP layer needs to retransmit messages, including:

[0073] If it is detected that the data retransmission timer of the TCP layer expires, it is determined that the TCP layer needs to retransmit the message;

[0074] Or, when it is detected that a preset number of confirmation indications are continuously received. ...

Embodiment 3

[0087] The embodiment of the present invention provides a wireless network device, such as Figure 4 shown, including:

[0088] The first receiving unit 41 is used for receiving the TCP message retransmission request sent by the terminal;

[0089] The first sending unit 42 is configured to retransmit the sent data message corresponding to the terminal based on the TCP message retransmission request; or, retransmit the data to be sent corresponding to the terminal; or, The data message corresponding to the terminal is assembled, or split, or repackaged, and then sent; wherein, the data message includes the sent data message and / or the data to be sent.

[0090] Here, it should be noted that the receiving the TCP message retransmission request from the terminal side may be that the terminal sends the retransmission request to the wireless network device when the terminal detects that its TCP layer needs to retransmit the message.

[0091] The message retransmission request can ...

Abstract

The invention discloses an information sending method, wireless network equipment and a terminal. The method comprises the following steps: receiving a TCP message retransmission request sent from a terminal; retransmitting the sent data message corresponding to the terminal based on the TCP message retransmission request; or retransmitting the to-be-sent data corresponding to the terminal; or assembling, splitting or repackaging the data message corresponding to the terminal, and then sending the same, wherein the data message comprises the sent data message and / or the to-be-sent data.

Description

technical field [0001] The invention relates to transmission management technology in the communication field, in particular to an information sending method, wireless network equipment and a terminal. Background technique [0002] At present, the TCP protocol uses mechanisms such as fast retransmission to ensure the quality of service. In the case of terminal cellular access, because the TCP side cannot know the transmission status of the wireless side, there may be cases where the wireless side has successfully transmitted or is still transmitting, but the server within a certain period of time The case where a packet was not received. In addition, in the fast retransmission mechanism, there may be cases where uplink ACK messages are successfully sent on the wireless side but not received by the server side, and the server will continuously send confirmation messages to start fast retransmission. Contents of the invention [0003] In view of this, the object of the pres...
