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.
Claims20
Network equipment, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- switching a call session from using a first signaling path to using a second signaling path, wherein the first signaling path is enabled via a voice over long term evolution core network service;
- wherein the second signaling path is initiated in response to the first signaling path being initiated to signaling server equipment;
- wherein the second signaling path is established as a function of a web real-time communication protocol associated with execution of a wrapper application via web application server equipment, and wherein the web real-time communication protocol is not associated with the voice over long term evolution core network service;
- wherein the switching of the call session is performed based on an expiration of time as measured by a failure timer;
- and
- wherein the failure timer is started based on detecting a failure associated with the call session.
A method, comprising:
- monitoring, by equipment comprising a processor, a first signaling path to signaling server equipment for a failure of a call session, wherein the first signaling path is established as part of a voice over long term evolution core network service;
- detecting, by the equipment, the failure of the call session;
- initiating, by the equipment, a failure timer that is used to determine, as a function of an elapse of time as measured by the failure tinier, that the call session has failed;
- in response to the call session being determined to have failed, facilitating, by the equipment, switching the call session from using the first signaling path to using a second signaling path;
- and
- establishing, by the equipment, the second signaling path as part of an instantiation of a wrapper application associated with a web real-time communication protocol that is not a voice over long term evolution protocol used with the voice over long term evolution core network service.
A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
- monitoring a first signaling path to signaling server equipment for a failure of a call session, wherein the first signaling path is established according to a voice over long term evolution core network service;
- detecting the failure of the call session;
- initiating a failure timer that is used to determine that the call session has failed after expiration of a defined time period;
- and
- in response to the failure of the call session, switching, by the equipment, the call session from using the first signaling path to using a second signaling path, wherein the using the second signaling path comprises establishing the second signaling path based on a wrapper application initiated according to a web real-time communication protocol, and wherein the web real-time communication protocol is not applicable to usage of the voice over long term evolution core network service.
