you need have service periodically call trafficstats apis current statistics, , store results. e.g. delta between 2 invocations of getmobiletxbytes() number of bytes received during time period.

of course, if pulls battery out of phone, you'll lose statistics since last invocation of service. set frequency of updates according needs (every hour versus every minute).
