Call Transfer via Near Field Communication Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current call transfer methods are inefficient and user-unfriendly, especially in crowded areas, as they fail to effectively locate the called user nearby, leading to poor call transfer efficiency and user experience.
Innovation Solution
A call transfer method using near field communication (NFC) to query and update the call transfer target by sending a local number query request to a second terminal, detecting the validity of the NFC link, and updating the call transfer target when the link is invalid, ensuring efficient call transfer even when terminals are not in the same local area network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If call transfer is set to transfer calls to another terminal when the user cannot answer, then the call can be transferred to a remote terminal, but the called user cannot be found quickly when in a crowded area, leading to poor call transfer efficiency
Solution Approach 1:
The patent introduces a position management server as an intermediary that receives position information from both the calling terminal and called terminal, processes this data, and provides guidance information to help the calling user locate the called user in crowded areas, thereby resolving the time loss problem without compromising call transfer reliability
Solution Approach 2:
The system implements feedback by continuously monitoring the relative positions of calling and called terminals, providing real-time guidance information (such as direction and distance) to the calling user, which enables quick location of the called user while maintaining reliable call transfer functionality
2Productivity
If call transfer is used to transfer calls to nearby terminals, then call transfer efficiency is improved, but the system becomes complex requiring position management servers and continuous position information exchange
Solution Approach 1:
The position management server performs multiple functions including receiving position information from terminals, calculating relative positions, generating guidance information, and managing call transfer coordination, thereby reducing the need for separate dedicated components and reducing overall system complexity while maintaining high call transfer efficiency

Function Achieved in This Case
Improves call transfer efficiency and user experience by enabling successful call transfer to nearby terminals, ensuring that the call is answered even when the original user is unavailable, and provides timely location-based updates to the caller.

AI summary
Embodiments of the present invention disclose a call transfer method and terminal. The embodiments of the present invention includes: sending, by a first terminal, a local number query request to a second terminal by using a near field communication link, where the local number query request is used to request the second terminal to query a local number of the second terminal; receiving, by the first terminal, the local number of the second terminal that is sent by the second terminal; and sending, by the first terminal, a call transfer request to a network side according to the received local number of the second terminal, where the call transfer request is used to request the network side to update a call transfer target of the first terminal to the local number of the second terminal. According to the call transfer method provided in the embodiments of the present invention, a problem is resolved that a user that uses a call-transferred-to terminal cannot notify a user of a call transfer terminal of related important information in a timely manner.
