Abstract

A method of controlling wireless communications is provided. A first call is received at a first distributed mobile architecture (DMA) server from a first mobile communication device. The first DMA server communicates with the first mobile communication device via a first wireless communication protocol. A second call is received at the first DMA server from a second mobile communication device. The first DMA server communicates with the second mobile communication device via a second wireless communication protocol. Voice information associated with the first call is converted to first packet data and voice information associated with the second call to second packet data. The first packet data and the second packet data are routed via a private Internet Protocol (IP) network to at least one second DMA device, where the first call is accessible to a first destination device and the second call is accessible to a second destination device via the at least one second DMA device.
