Real-Time Charging Mode Modification for Mobile Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies require termination and re-establishment of calls when the calling party's tariffs are insufficient, leading to inconvenient user experiences and high network signaling overhead.
Innovation Solution
A method and apparatus for modifying the charging mode in real-time by transmitting signaling messages using SIP or NAS protocols to swap the roles of calling and called parties, allowing the call to continue without interruption, thus reducing network signaling overhead and maintaining the call.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the current call is terminated and roles are modified to re-establish a new call, then the calling and called parties can be switched, but the operation becomes complicated and user experience deteriorates
Solution Approach 1:
The patent implements dynamic role switching during an active call by allowing the called party to send a role modification request message to the network side device. This enables the calling and called party roles to be switched in real-time without terminating the call, making the system adaptable while maintaining operational simplicity.
Solution Approach 2:
The network side device acts as an intermediary to facilitate the role switching process. It receives the role modification request from the called party, processes the role switch, and manages the re-establishment of the call, thereby simplifying the operation for end users while maintaining system control.
2Adaptability or versatility
If the current call is terminated and re-established with swapped roles, then the charging mode can be modified, but the signaling overhead increases
Solution Approach 1:
The patent enables the called party to send a role modification request message during the active call to pre-switch roles before any call termination occurs. This preliminary action allows the charging mode to be modified in real-time without requiring call termination and re-establishment, thereby reducing signaling overhead.
Solution Approach 2:
The patent maintains call continuity by allowing role modification during an active call through a streamlined signaling process. The called party sends a request message, the network side device processes the role switch, and the call continues without interruption, preserving useful action while minimizing additional signaling overhead.
3Reliability
If the calling party continues the call with insufficient tariffs, then the call may be interrupted by the network, but switching roles requires complicated operations
Solution Approach 1:
The network side device serves as an intermediary that automatically manages the role switching process when the called party sends a role modification request. This intermediary function handles the complexity of role switching and call re-establishment, making the process simple for users while ensuring call continuity even when tariffs are insufficient.
Solution Approach 2:
The patent implements dynamic role switching that can occur during an active call without requiring manual termination and re-establishment. The system adapts to tariff issues by allowing the called party to request a role switch, which the network processes dynamically to maintain call reliability while simplifying operations.

AI summary
A method and an apparatus for modifying a charging mode, a mobile terminal and a network side device are provided in the present disclosure. The method includes: transmitting a signaling message containing information of modifying roles of current calling and called parties or modifying a charging mode to a network side, after receiving a signaling message containing calling information; and receiving a signaling message transmitted by the network side that contains information that the roles of the current calling and called parties are modified, or the charging mode is modified. In the present disclosure, calling and called parties can be modified in real time through network, which is convenient to operate, and can save network signaling overhead and can avoid a current call being interrupted by the network side due to insufficient tariffs of a current calling party.
