SIP Enabler System for Concurrent Application Execution

The patent introduces an enabler system comprising an access module, event dispatcher, and communication interface that mediates between applications and the SIP signaling module. The access module receives actions from applications, the event dispatcher filters and routes events to appropriate applications, and the communication interface manages the interaction flow. This intermediary layer prevents direct conflicts between multiple applications while maintaining their ability to access IMS services through standardized interfaces.

The patent segments the resource management functionality into distinct modular components: the access module handles application-specific actions, the event dispatcher manages event filtering and routing based on application interests, and the communication interface coordinates overall interaction. This segmentation allows multiple applications to share SIP signaling resources concurrently while each component handles specific aspects of resource management, reducing overall system complexity despite supporting multiple applications.

The patent creates a universal enabler system that provides common access mechanisms for all applications to interact with the SIP signaling module through standardized interfaces. The access module, event dispatcher, and communication interface collectively provide multi-functional capabilities that serve multiple applications simultaneously. While this standardized approach enables common service access, the system maintains application control through the event dispatcher's ability to filter and route events based on application-specific interests and the access module's ability to process application-specific actions.
