Method and device for frame acknowledgment

Abstract

A method for frame acknowledgement, comprising bearing a delayed acknowledgement instruction into a data frame; the delayed acknowledgement instruction configured to instruct a return acknowledge response when it has free physical resources; and transmitting the data frame having the delayed acknowledgement instruction attached thereto.

What is claimed is: 
     
         1 . A method for frame acknowledgement, comprising:
 bearing a delayed acknowledgement instruction into a data frame; the delayed acknowledgement instruction configured to instruct a return acknowledge response when it has free physical resources; and   transmitting the data frame having the delayed acknowledgement instruction attached thereto.   
     
     
         2 . The method of  claim 1 , wherein, bearing the delayed acknowledgement instruction into the frame header of data frame. 
     
     
         3 . The method of  claim 1 , wherein, the delayed acknowledgement instruction configured to instruct a return acknowledge response of all unacknowledged frames. 
     
     
         4 . The method of  claim 1 , further comprising:
 caching the frames that do not receive the acknowledgement;   determining whether a caching capacity threshold is reached;   triggering a transmitting of delayed acknowledgement instruction, when the caching capacity threshold is reached.   
     
     
         5 . A device for frame acknowledgement, comprising:
 encapsulation module, configured to bear a delayed acknowledgement indication in data frame, wherein the delayed acknowledgement indication indicates a return acknowledge response when it has free physical resources;   sending module, configured to deliver the data frame of the carried delayed acknowledgement indication out.   
     
     
         6 . The device of  claim 5 , wherein, the encapsulation module bears the delayed acknowledgement indication in the frame header of data frame. 
     
     
         7 . The device of  claim 5 , wherein, the delayed acknowledgement indication indicates return of all the unacknowledged frame acknowledgements. 
     
     
         8 . The device of  claim 5 , further comprising:
 caching module configured to cache the unacknowledged frame;   judging module configured to judge whether caching capacity threshold is met; and   processing module configured to trigger a delivering of delayed acknowledgement indication when the caching capacity threshold is reached.
