Is there any way to cancel the "call" request?

[ngokyuen]

I have used the "call" function to upload data to meteor web server on my android mobile app, but sometimes the client can not reach the network. I would like to prevent the request after the client mobile has tried to send data at the first time and not to try to send again.

I mean that i would like to set the system(client side) is only try to send data one time, if the connection is fail or cause exception then the "call" request will be cancelled and it (ddp) will not to try to upload.
