Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further described in more detail.
Embodiment one,
The embodiments of the invention provide a kind of method for sending information, applied to Wireless Communication Equipment, as shown in figure 1, including：
Step 101：Receive the TCP message repeat requests that terminal is sent；
Step 102：Based on the TCP message repeat requests, the corresponding data-message of transmission of the terminal is carried out
Resend；Or the corresponding data to be sent of the terminal are retransmitted；Or by the corresponding number of the terminal
Assembled or split according to message or sent after repacking；Wherein, the data-message, which includes, has sent data-message
And/or data to be sent.
Here can be that terminal is examined, it is necessary to which explanation, described to receive the TCP message repeat requests sent end side
When measuring its TCP layer needs to retransmit message, the repeat requests are sent to the Wireless Communication Equipment.
The flag information of data to be retransmitted can also be carried in the TCP message repeat requests；
Wherein, the flag information of data to be retransmitted includes：Internet protocol (IP) layer, and/or, transmission control protocol
(TCP, Transmission Control Protocol) layer information, and/or, packet data convergence protocol (PDCP,
Packet Data Convergence Protocol) information；
Specifically, the IP layers or TCP layer information include：IP Bale No.s, and/or destination address, and/or port numbers；It is described
PDCP floor information includes No. PDCP.
That is, terminal when sending information re-transmission request, it is necessary to need the letter that sends at least carrying in the request
The identification number or numbering of breath.
It is understood that the processing that Wireless Communication Equipment can be transmitted data again needs to be based on the wireless network
Network equipment has cached the data message of the terminal in advance, and the processing that cache information is obtained below for Wireless Communication Equipment is carried out
Explanation：
Before receiving the TCP message repeat requests that terminal is sent, methods described also includes：Wireless Communication Equipment side caches
The information that the terminal is sent；Wherein, described information includes：TCP message, and/or, buffer setting has the information of cache tag.
Wherein, the information for being provided with cache tag can be to set correlation at the specified data bit in described information
Caching sign, can use 0 represent need not cache, using 1 represent need to cache.
Accordingly, also the information of caching can regularly be deleted in Wireless Communication Equipment side, possesses following two fields
Scape：
Scene one,
Specifically, the information that the caching terminal is sent, including：Wireless Communication Equipment sets caching timer；Inspection
Measure the caching timer then, delete the described information of caching.
Wherein, the Wireless Communication Equipment sets caching timer, specifically includes：The duration of the caching timer is set
Be set to retransmission timer duration or, be arranged to be longer than retransmission timer duration.
The duration of the retransmission timer can according to actual conditions set duration, at present TCP layer can set one
Data retransmission timer.
Scene two,
After the information that the caching terminal is sent, methods described also includes：Receive the finger that the terminal is sent
Show message, the described information of caching is deleted according to the instruction message.
Wherein, the configured information that the terminal is sent can include the identification number of the information of the caching to have been deleted.
After the processing scene of above-mentioned steps 101- steps 102, methods described also includes：Wireless Communication Equipment is to terminal
Side feedback replying message for TCP message repeat requests.
Wherein, it is described for comprising at least at least one of following information in the replying message of TCP message repeat requests：
To the confirmation of repeat requests；
To the refusal information of repeat requests；
The reason for repeat requests are refused.
Specifically, it is described to end side repeat request confirmation message, including：Wireless Communication Equipment check whether be cached with
Effective data to be retransmitted corresponding to the TCP message repeat requests, if so, then in returning for TCP message repeat requests
The confirmation to repeat requests is carried in multiple message；If it is not, carried in for the replying message of TCP message repeat requests
To the refusal of repeat requests.
That is, when data corresponding with the TCP message repeat requests are preserved in Wireless Communication Equipment side, to end
Feedback acknowledgment information is held, if corresponding to not preserving during data, namely can not retransmission information to terminal feeding back unsuccessful.Judge
Data to be retransmitted corresponding to whether preserving the sign number of data corresponding to the message re-transmission requests or can be numbered according to
To determine.
Specifically, the re-transmission confirmation message includes：At least carried in for the replying message of TCP message repeat requests
Treat the mark of retransmission information.
Further, described the reason for refusing repeat requests, includes following at least one：
Information is out of date；Such as can be by setting a flag to be indicated；
Information is not present；
Information re-transmission sends failure.
It can be seen that by using such scheme, it becomes possible to when receiving the repeat requests of terminal, according to the number of itself preservation
Handled according to executing data retransmission.So, it becomes possible to when network data is preserved in Wireless Communication Equipment, avoid by terminal
Resend, retransmitted so as to reduce the data eated dishes without rice or wine；And agreement need not be modified, ensure that compatibility.
