Abstract

Fault-tolerant signaling in a Long Term Evolution (LTE) network architecture is disclosed. A method can comprise initiating a primary signaling path to a signaling server device; in response to the initiating, establishing an alternate signaling path to a web application server device, wherein a call session is established over the primary signaling path; monitoring the primary signaling path for a session failure; and in response to the session failure, switching the call session from using the primary signaling path to using the alternate signaling path.
