1. A method comprising: detecting a failure condition relating to a first distributed mobile architecture (dMA) gateway (dMAG) at a dMAG management system, wherein the dMAG management system is in communication with at least the first dMAG, a second dMAG, and a plurality of dMA nodes; determining that the first dMAG is not operational or is otherwise offline based on the failure condition; selecting, at the dMAG management system, the second dMAG; sending a first notification from the dMAG management system to the second dMAG, wherein the first notification instructs the second dMAG to take over operations from the first dMAG; sending a second notification from the dMAG management system to at least one dMA node of the plurality of dMA nodes, wherein the at least one dMA node is configured to connect a call from a mobile station to an external system via the first dMAG, and wherein the second notification indicates that the second dMAG has taken over the operations from the first dMAG and that the at least one dMA node is to connect subsequent calls from the mobile station to the external system via the second dMAG; and sending a third notification from the dMAG management system to the external system, wherein the external system is configured to connect calls to the mobile station via the first dMAG, and wherein the third notification indicates that the second dMAG has taken over the operations from the first dMAG and indicates that the external system is to connect subsequent calls to the mobile station via the second dMAG.
