## Abstract

A mobile device and method for management of communication from a mobile device capable of multi-tasking. The method includes capturing a request from at least one application executed on the mobile device for data communication through a network interface of the mobile device; identifying the at least one application by interrogation of an operating system of the mobile device; determining for the identified one application data communication access rights; and autonomously communicating through the network interface for the at least one application and independently communicating with the at least one application without interfering with normal operation of the at least one application, when the data communication access rights require regulating bandwidth usage by the at least one application.
