Base Station Call Waiting Compatibility Between Mobile and Cluster Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies fail to provide call waiting prompts to called terminals when a mobile system transitions into a cluster system or vice versa, as the base station cannot determine the status of called terminals in mixed call scenarios.
Innovation Solution
A method and system where a base station updates the status of called terminals to a busy state through mobile and cluster processors, allowing call waiting prompts to be sent when a second call is initiated, ensuring compatibility between mobile and cluster call waiting systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the base station operates independently in mobile or cluster systems, then the system operation is simple, but the base station cannot know the status of called terminals when transitioning between mobile and cluster systems
Solution Approach 1:
The patent introduces status update messages as intermediary carriers that transfer terminal status information between the base station and processors. When a terminal transitions between mobile and cluster systems, the base station sends status update messages to the mobile processor or cluster processor, which then respond with the terminal's current status, enabling the base station to know whether the terminal is busy or available without direct access to processor internal states.
Solution Approach 2:
The patent divides the information management function into separate components: the base station handles call routing and messaging, while the mobile processor and cluster processor independently manage their respective terminal status information. This segmentation allows each component to operate independently while maintaining information flow through standardized status update messages, resolving the contradiction between operational simplicity and information availability.
2Reliability
If the base station queries terminal status in mixed call scenarios, then call waiting prompt information can be sent, but the base station cannot determine the status of called terminals without processor cooperation
Solution Approach 1:
The patent creates a universal status update mechanism that works across both mobile and cluster systems. The base station uses the same status update message format and processing logic regardless of whether it's dealing with a mobile terminal or cluster terminal, enabling reliable call waiting prompt delivery through a unified approach that manages complexity rather than increasing it.
Solution Approach 2:
The patent implements a feedback loop where the base station sends status update messages to processors, receives status information in response, and uses this feedback to determine whether to send call waiting prompt information. This feedback mechanism ensures reliable prompt delivery by base station making informed decisions based on actual terminal status while maintaining manageable complexity through automated status tracking.
3Adaptability or versatility
If status information is updated in both mobile and cluster processors, then compatibility between systems is achieved, but the coordination overhead increases
Solution Approach 1:
The patent performs preliminary status updates by sending status update messages to both mobile and cluster processors when a terminal transitions between systems. This preliminary action ensures both processors have current status information before call waiting operations occur, achieving system compatibility without requiring repeated coordination during actual call operations, thus minimizing time loss.
Solution Approach 2:
The patent merges the status update operations for mobile and cluster processors into a unified messaging protocol. The base station sends a single type of status update message that can be processed by either processor type, and both processors use the same status information format. This merging approach achieves full system compatibility while reducing coordination overhead by eliminating the need for separate update procedures for different processor types.

AI summary
The present invention discloses a method, system and base station for implementing compatibility between mobile call waiting and cluster call waiting, wherein the method includes: when a first calling terminal initiates a first call, the base station receiving access information transmitted by a called terminal of the first call, and making a request to a mobile processor and a cluster processor for updating status information of terminals involved in the first call to a busy state; according to the request from the base station, the mobile processor and the cluster processor updating the status information of the terminals to the busy state; when a second calling terminal initiates a second call, the base station querying out that the status of the called terminal of the second call is busy, and transmitting call waiting incoming call prompting information to the called terminal of the second call. In the technical solution provided by the present invention, the statuses of the terminals connected by the first call are updated to the busy state by the mobile processor and the cluster processor, and when the second calling terminal initiates the second call to the corresponding terminals, the base station transmits the call waiting incoming call prompting information to the corresponding terminals, thus enabling the compatibility between the mobile call waiting and the cluster call waiting.
