Service Control Point Call Management via User Info Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current communication networks, called terminals can only receive digital signals and lack sufficient user information about calling terminals, making it difficult for users to decide whether to answer calls, especially in situations where phonebooks are limited or lost, leading to disturbances in important work or events.
Innovation Solution
A method and system where a Service Control Point (SCP) inquires user information of the calling terminal and sends it to the called terminal, allowing the called terminal to selectively answer or reject calls based on the received information, using mechanisms like USSD messages, short messages, or IVR calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the called terminal only receives digital signals without additional user information, then the communication network structure remains simple, but the user cannot make informed decisions about answering calls
Solution Approach 1:
The patent introduces an intermediary system consisting of the Service Control Point (SCP) and Message Transfer Point (MTP) to bridge the gap between the calling terminal and called terminal. The SCP queries user information from the HLR database and transfers it through the MTP to the called terminal via USSD messages, enabling information delivery without fundamentally redesigning the entire network architecture.
Solution Approach 2:
The system performs preliminary actions by querying and preparing user information from the HLR database before the called terminal needs to make a decision. The SCP retrieves the calling terminal's user information in advance and makes it available to the called terminal through standardized message interfaces, so the information is ready when needed for call acceptance decisions.
2Loss of information
If the terminal phonebook stores all possible numbers, then complete user information can be displayed, but the phonebook capacity is exceeded and the terminal cannot handle all communication requirements
Solution Approach 1:
The patent transitions from two-dimensional local storage (terminal phonebook with limited capacity) to a multi-dimensional solution that combines local storage with network-based database access. The HLR database provides an additional dimension of storage capacity, while the USSD message system provides another dimension for information transmission, allowing complete user information to be delivered without expanding terminal phonebook capacity.
3Reliability
If the called terminal answers all calls tentatively to ensure no important calls are missed, then call coverage is maximized, but important work and events are disturbed by unwanted calls
Solution Approach 1:
The system implements feedback by providing the called terminal with user information about the calling terminal before the call decision is made. This feedback loop allows the called user to make an informed decision based on the received information (such as caller identity, call type, or other relevant data), balancing the need to answer important calls with the need to avoid unwanted disturbances.
Data Source
AI summary
A method, a system, and a service control point (SCP) for realizing call management are provided. The method for realizing call management includes: inquiring user information of a calling terminal according to a call request message of the calling terminal; sending the user information of the calling terminal, over a called terminal; and exercising a corresponding call control according to a response made by the called terminal to a call carrying the user information of the calling terminal. With the method, system, and SCP for realizing call management provided by the embodiments of the present invention, the called terminal may selectively answer the call according to the user information of the calling terminal, thereby avoiding disturbing the work due to answering some unnecessary calls.
