Abstract: A self-organizing IP multimedia subsystem exhibiting node splitting and node merging functions wherein any node within the self organizing IP multimedia subsystem may assume any role thereby providing node balancing and fault tolerance to an overall network.

Abstract: An information collection device includes a signaling packet analysis section which extracts communication device information from a signaling packet, the communication device information identifying a communication device that transmits the signaling packet when connecting to another device.

Abstract: An overlay service network and method for delivering a multimedia service. The overlay service network comprises a user interface for subscribers to request an available service as a requested service, a register server for registering and storing a database of available services, a plurality of service nodes for executing at least one available service and a controller for receiving a request for an available service, searching the register server for the requested service, selecting one or more of the plurality of service nodes to execute the requested service and establishing a chaining sequence between a node requesting the service, the one or more selected execution nodes and a destination node to execute the requested service.

Abstract: A virtualized telecom system and a method for managing service continuity and mobility in a virtualized telecom system. The system comprises a plurality of execution nodes each configured to execute a network function by registering; and a manager node for registering each of the plurality of execution nodes, assigning a node identifier (Node ID) to each of the plurality of execution nodes, periodically polling each of the plurality of execution nodes for a status, and issuing control instructions to each of the plurality of execution nodes based upon the status of a respective execution node. Each of the plurality of execution node responds to the polling by transmitting its status to the manager node. The status includes runtime information and pre-configuration information.
