CDMA Dual-Standby Terminal Short Message Scheduling

The patent applies preliminary action by establishing service channel links and preparing message queues in advance. When a short message service is initiated, the terminal pre-establishes the necessary communication channels and prepares the processing framework, allowing the actual message processing to proceed efficiently without delaying other services. The voice and data services are pre-configured to be deferred rather than immediately interrupted.

The patent implements dynamics by making the service processing flexible and adaptive. The terminal dynamically adjusts the processing priority based on the current service state, using state machines to transition between different service modes. When short message service is active, voice and data services are dynamically deferred; when short message service completes, other services are dynamically reactivated. This dynamic adjustment resolves the contradiction by making the system responsive rather than static.

The patent applies segmentation by dividing the dual-standby terminal into two independent service systems, each with its own service channel link and state machine. Instead of managing one complex unified system, the terminal segments the short message services for each user into separate manageable units. Each segment can be processed independently with its own resource allocation, reducing the overall management complexity while maintaining dual-standby functionality.

The patent implements universality by creating a generic service management framework that handles both users' short message services through the same mechanism. The service channel link establishment, message queue management, and state transition logic are universal across both users. This multi-functional approach allows the terminal to manage dual-standby services without duplicating the entire management system, reducing complexity while expanding capacity.

The patent applies segmentation by dividing the single radio frequency module's resources into separate service channel links for different users and services. Through logical resource partitioning, the terminal creates independent communication paths within the unified hardware structure. This segmentation allows voice, data, and short message services to operate in separate logical channels, reducing interference while maintaining the simplified single-radio-frequency structure.

The patent implements the intermediary principle by introducing service channel links as mediators between the single radio frequency module and multiple services. These service channel links act as intermediate layers that manage resource allocation and signal routing. The mediators coordinate access to the shared radio frequency resource, preventing direct service interference while maintaining the benefit of a simplified device structure with a single radio frequency module.
