Voicemail Time Zone Notification for Roaming Subscribers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunications subscribers abroad face difficulties in determining the time elapsed since a call was made and the best time for a return call due to time zone differences, as conventional methods only provide time stamps from the home country, requiring manual calculation.
Innovation Solution
A method that transmits information about both the home country's time zone and the foreign country's time zone via an automatic voice message when a mailbox is accessed, allowing the subscriber to derive the local time of the call arrival and optimal callback time without manual calculation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only the home country time zone is provided in the mailbox message, then the information structure remains simple, but the subscriber abroad cannot easily determine the local call arrival time and optimal callback time
Solution Approach 1:
The patent combines multiple time zone information elements (home country time zone, foreign country time zone, and their relationship) into a single integrated message transmitted to the subscriber. This merging of information elements resolves the contradiction by providing comprehensive time zone data without creating separate communication channels or complex systems.
Solution Approach 2:
The system performs preliminary calculation and preparation of time zone conversion information before the subscriber needs it. The server automatically determines the subscriber's current time zone, calculates the home country time zone, and prepares the time difference information in advance, so that when the subscriber accesses the mailbox, the information is already ready and requires no manual calculation by the subscriber.
2Productivity
If time zone information is transmitted via automatic voice message, then the subscriber receives immediate information without manual calculation, but the information transmission requires additional system processing
Solution Approach 1:
The system uses the existing automatic voice message infrastructure to deliver time zone information, leveraging an already-established service mechanism. The server automatically generates and plays the voice message without requiring manual intervention from operators or additional complex communication channels, thus improving information delivery efficiency while maintaining reasonable system complexity.
3Reliability
If both home country and foreign country time zone information are provided, then the subscriber can easily determine optimal callback time, but the message length and information processing increase
Solution Approach 1:
The server performs preliminary determination of the subscriber's current time zone and pre-calculates the home country time zone and time difference before the subscriber accesses the mailbox. This advance preparation ensures that when the subscriber listens to the voice message, all time zone information is already processed and ready, eliminating any additional processing time for the subscriber and ensuring accurate callback timing information is immediately available.
Data Source
AI summary
A method for informing a telecommunications subscriber in a foreign country of at least one item of information. The telecommunications subscriber is assigned to a telecommunications provider in a home country via a customer relationship. The home country has a first time zone. The foreign country has a second time zone. The at least one item of information comprises the first time zone and the second time zone and is transmitted to the telecommunications subscriber when a mailbox provided by the telecommunications provider is used. The method includes transmitting the at least one item of information to the telecommunications subscriber via a voice message, announcing the voice message via an automatic voice message, and then playing back a call stored in the mailbox.
