Start and stop gprs bearer connection

Hi,

Thanks for the reply … Now i’m able to close the bearer… and receiving the proper response from
if(0==wip_bearerclose(b)){ print(" bearer closed")}

But some times suddenly IP gets terminated after uploading the data , Do I need to restart my entire device again ,? becoz I called the open_and_start_bearer();, it couldnt get connected , i.e it didnt generated any event “evh_bearer” handler …
