Abstract

Methods and systems to control wireless communications are provided. A particular network communication system includes a plurality of distributed mobile architecture gateways. Each distributed mobile architecture gateway includes at least one interface to communicate with one or more legacy communication networks and each distributed mobile architecture gateway also includes a data network connection. The data network connection is adapted to connect to at least one other distributed mobile architecture gateway of the plurality of distributed mobile architecture gateways. Additionally, the system includes a private Internet Protocol (IP) network connecting each distributed mobile architecture gateway to a respective set of distributed mobile architecture (DMA) servers. Each DMA server is coupled to a respective base transceiver station, and the private IP network also connects each DMA server in a particular set of DMA servers to the DMA servers in the other sets of DMA servers.

The system of claim 1, wherein the first DMAG includes a community location register database, the community location register database including a particular home location register for each of the second plurality of DMA servers designated to communicate via the second DMAG and each particular home location register including information related to one or more wireless communication devices designated to communicate via the respective DMA server.

6. The system of claim 1, wherein the first DMAG includes a visitor location register database, the visitor location register database including a particular visitor location register for each of the first plurality of DMA servers designated to communicate via the first DMAG and each particular visitor location register including information related to one or more wireless communication devices that are temporarily registered to communicate via the respective DMA server.

7. The system of claim 1, wherein the first DMAG includes a visitor location register gateway comprising information based on a visitor location register at each of the plurality of DMA servers.

8. The system of claim 1, wherein the first DMAG includes a global title (GT) to determine a carrier of a roaming wireless communication device based on at least one of a network address of the roaming wireless communication device and an international mobile subscriber identity (IMSD of the roaming wireless communication device.

9. The system of claim 1, wherein the legacy communication network is an IP network and the call is a voice-over IP (VoIP) call.

10. The system of claim 1, wherein the legacy communication network is a wireless data network.

11. A method of routing calls via a communications network, the method comprising:

receiving a call at a first distributed mobile architecture gateway (DMAG) via a legacy communication network, wherein the voice traffic is placed to a first wireless communication device;

identifying that the first wireless communication device is adapted to communicate via a first DMA server based on wireless communication device registration data stored at the first DMAG, wherein the first DMA server is one of a plurality of DMA servers designated by a communications service provider to communicate via the first DMAG; and

routing the voice traffic from the first DMAG to the first DMA server via a private Internet Protocol (IP) network.

12. The method of claim 11, wherein the first wireless communication device is designated to communicate via the first DMA server.

13. The method of claim 11, wherein the first mobile communication device is designated to communicate via a second DMA server and is temporarily registered to communicate via the first DMA server, and wherein the second DMA server is one of the first plurality of DMA servers designated to communicate via the first DMAG.

14. The method of claim 13, further comprising registering the first wireless communication device in a home location register associated with the second DMA server and temporarily registering the first wireless communication device in a visitor location register associated with the first DMA server, wherein the home location register associated with the second DMA server and the visitor location register associated with the first DMA server are stored at the first DMAG.
