MTC Server Content Availability Switching for Continuous Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine-type communication (MTC) systems fail to ensure continuous content delivery as they rely on device IDs for session initiation, leading to content unavailability when equipment cannot provide the intended content.
Innovation Solution
A communication method where an MTC server broadcasts target content, receives availability information from candidate equipment, selects suitable devices, establishes session connections, and monitors for content availability, automatically switching to new connections if the current equipment becomes unavailable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If session connection is established based on device ID, then session initiation is simple, but content availability cannot be ensured when equipment becomes unable to provide intended content
Solution Approach 1:
The patent implements feedback by having MTC equipment send availability information to the network side device, which then monitors whether the equipment can still provide the intended content. This feedback mechanism allows the system to detect when equipment becomes unavailable and trigger appropriate actions, resolving the contradiction between simple session initiation and reliable content delivery.
Solution Approach 2:
The patent applies preliminary action by pre-negotiating content availability before establishing the session connection. The network side device receives availability information from candidate MTC equipment and determines which equipment can provide the intended content before finalizing the connection, ensuring content availability from the start.
2Reliability
If pre-negotiation is performed to determine content availability, then content-based communication is achieved, but communication process becomes more complex
Solution Approach 1:
The patent extracts the content availability determination process as a separate preliminary step from the main session establishment process. By separating these functions, the system can perform content-based matching without complicating the core session management, reducing overall process complexity while maintaining reliability.
Solution Approach 2:
The patent performs content availability determination as a preliminary action before session establishment. This allows the complex content-matching logic to be executed in advance, so that once the session is established, the communication can proceed without repeated complexity, effectively managing the trade-off between reliability and process complexity.
3Reliability
If monitoring is implemented to detect equipment unavailability, then continuous content delivery is ensured, but system complexity increases
Solution Approach 1:
The patent uses feedback through monitoring equipment status and content availability, triggering automatic reconnection when unavailability is detected. This feedback-driven approach ensures continuous content delivery while keeping the monitoring system relatively simple, as it only needs to detect unavailability rather than manage complex content routing.
Solution Approach 2:
The patent implements self-service by enabling the system to automatically detect equipment unavailability and initiate reconnection without human intervention. This automation reduces the need for complex manual monitoring systems while ensuring continuous content delivery, as the system serves itself by detecting and resolving availability issues.
