Terminal Dialing Correction Using Location Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face a high network call loss rate due to incorrect dialing, especially during international roaming, as existing methods fail to accurately ensure the correctness of dialed numbers before connecting calls.
Innovation Solution
A dialing method and device that acquire dialing auxiliary data, including home and roaming location information, to judge and correct dialed numbers before calling, ensuring compliance with dialing rules by adding or modifying prefixes as necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network judges the correctness of the dialed number after receiving the number, then the connection can be completed, but the call loss rate increases because incorrect numbers cannot be corrected in time
Solution Approach 1:
The terminal performs preliminary judgment and correction of the dialed number before sending it to the network. The terminal acquires dialing auxiliary data information (including home location and roaming location information), judges whether the dialed number conforms to dialing rules, and corrects incorrect numbers before transmission. This preliminary action prevents incorrect numbers from reaching the network, reducing call loss rate while maintaining connection reliability.
2Ease of operation
If the terminal adds auxiliary functions like converting '+' numbers or automatically adding IP dialing prefixes, then dialing assistance is provided, but the accuracy of number reporting to the network cannot be guaranteed
Solution Approach 1:
The terminal establishes a feedback mechanism by acquiring dialing auxiliary data information (home location and roaming location) and using it to judge whether the dialed number conforms to dialing rules. The terminal corrects numbers based on this feedback from location information, ensuring accurate number reporting while maintaining ease of operation through automated judgment and correction.
3Measurement precision
If the terminal performs comprehensive judgment and correction of dialed numbers, then dialing accuracy improves, but the device complexity increases
Solution Approach 1:
The terminal uses universal dialing auxiliary data information (home location and roaming location information) that can be applied across multiple dialing scenarios. This multi-functional data structure enables the terminal to handle various dialing situations (domestic, international, roaming) with a single unified judgment mechanism, improving dialing accuracy without proportionally increasing device complexity.

AI summary
A dialing method and device are disclosed. The method includes: a terminal acquiring dialing auxiliary data information, wherein, the dialing auxiliary data information comprises home location information and/or roaming location information; after receiving a dialed number of a subscriber, the terminal judging whether the dialed number conforms to a dialing rule according to the dialing auxiliary data information; and in a case that the terminal judges that the dialed number does not conform to the dialing rule, correcting the dialed number, and calling out the corrected dialed number. With the method and device, a problem of a higher network call loss rate in the related art is solved, a dialing success rate of the subscriber is increased, and the user experience is improved.
