1. A method comprising:
- receiving a call routing request at a first distributed mobile architecture (DMA) node of a DMA network from a mobile switching center (MSC), wherein the first DMA node provides wireless service to a first coverage site of the DMA network, the DMA network including multiple coverage sites, and wherein the first DMA node is configured to receive all call routing requests for the DMA network from the MSC;
identifying, at the first DMA node, a second DMA node that provides wireless service to a second coverage site of the DMA network and that provides wireless service to a mobile subscriber device, wherein the second DMA node is identified based on information stored at a visitor location register (VLR) gateway included in the first DMA node, wherein the information stored at the VLR gateway identifies each mobile subscriber device visiting the DMA network and which DMA node of the DMA network provides wireless service to each of the mobile subscriber devices visiting the DMA network; and
sending a call routing message from the first DMA node via a peer-to-peer connection over an internet protocol network to the second DMA node, wherein the call routing message is associated with the mobile subscriber device.

Abstract
A method includes receiving a call routing request at a first distributed mobile architecture (DMA) node from a mobile switching center (MSC). The method includes identifying, at the first DMA node, a DMA node associated with a mobile subscriber device based on information included in a visitor location register (VLR) gateway accessible to the first DMA node. The VLR gateway identifies a set of visiting mobile subscriber devices. The method includes sending a call routing message from the first DMA node to the identified DMA node associated with the mobile subscriber device.

6. A method comprising:
-
sending a call routing request from a mobile switching center (MSC) to a first distributed mobile architecture (DMA) node of a DMA network, wherein the first DMA node includes a visitor location register (VLR) gateway that stores information that identifies each mobile subscriber device visiting the DMA network and which DMA node of the DMA network provides wireless service to each of the mobile subscriber devices visiting the DMA network, wherein the first DMA node provides wireless service to a first coverage site of the DMA network, the DMA network including multiple coverage sites, and wherein the first DMA node is configured to receive all call routing requests for the DMA network from the MSC; receiving an acknowledgement to the call routing request from the first DMA node, wherein the acknowledgement identifies a particular DMA node of the DMA network, and wherein the first DMA node is in communication with the particular DMA node via a peer-to-peer connection over an internet protocol network, wherein the particular DMA node is associated with a particular mobile subscriber device; and placing a call from the MSC to the mobile subscriber device via the particular DMA node. - View Dependent Claims (8, 9, 10)

11. A method comprising:
-
storing first registration information at a visitor location register (VLR) gateway, wherein the first registration information is received from a first distributed mobile architecture (DMA) node of a DMA network, wherein the first registration information is sent by the first DMA node to the VLR gateway in response to the first DMA node receiving a first registration request from a first visiting mobile subscriber that is located within a first coverage site of the DMA network, wherein the first coverage site is supported by the first DMA node, wherein the first registration information indicates that the first visiting mobile subscriber is located within the first coverage site, and wherein the VLR gateway is configured to store information that identifies visiting mobile subscriber devices at each coverage site of the DMA network, and wherein the first DMA node is configured to receive all call routing requests for the DMA network from a mobile switching center (MSC); and storing second registration information at the VLR gateway, wherein the second registration information is received from a second DMA node of the DMA network, wherein the second registration information is sent by the second DMA node to the VLR gateway in response to the second DMA node receiving a second registration request from a second visiting mobile subscriber that is located within a second coverage site of the DMA network, wherein the second coverage site is supported by the second DMA node, wherein the second coverage site is different from the first coverage site, wherein the first DMA node communicates with the second DMA node via a peer-to-peer connection over an internet protocol network, wherein the second registration information indicates that the second visiting mobile subscriber is located within the second coverage site, wherein the first visiting mobile subscriber is associated with a first home coverage site that is outside of the DMA network, wherein the second visiting mobile subscriber is associated with a second home coverage site that is outside of the DMA network, and wherein the VLR gateway stores information identifying which DMA node of the DMA network provides wireless service to each mobile subscriber device visiting the DMA network. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
