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.

LTE fault-tolerant signaling approach

In one example, a method includes monitoring conditions in a telecommunication service provider network, selecting a first path by which to connect a communication session between a first endpoint and a second endpoint, wherein the first path is a path through the network that is expected to satisfy a predefined level of performance for the communication session based on the conditions, connecting the first endpoint and the second endpoint via the first path, detecting a change in the conditions that results in the first path failing to satisfy the predefined level of performance, selecting a second path by which to connect the communication session, wherein the second path is a path through the network that is expected to satisfy the predefined level of performance for the communication session based on the conditions as changed, and initiating a handoff of the communication session from the first path to the second path.

Adaptable network communications

The system may provide automatic real-time filtering and information object selection, which may occur at the presentation layer. Presentations may be tailored on a per user basis. Users with different security levels can participate in a video conference call at the same time and only view what their security clearance allows.

Object-managed secured multicast system

A system and method for receiving performance measurements for a communications network, generating alerts based on each performance measurement and a corresponding performance threshold, receiving network traps from network elements of the communications network, each network trap being generated by the network element based on a process measurement and a corresponding process threshold and correlating the alerts and the network traps to generate correlated alerts.

To facilitate routing changes, a telecommunications network () includes a centralized network routing database () queried by each ingress switch upon receipt of a call by a calling subscriber (). In response to the query, the network routing database returns to the querying switch the identity on the next (downstream) switch in the routing path. The querying switch then translates the switch identity to establish the link to that next switch. Because each querying switch makes the necessary translation of the next switch identity to make the link to the next switch, the centralized network database need not concern itself with the particular characteristics of the switch. To make global routing changes, only the network routing database need be updated, not each individual switch.
