PoC Voice Mailbox Session Type Detection and Text Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice mailboxes in Push-To-Talk over Cellular (PoC) services are inefficient in one-to-many sessions, as they play voice prompts for each user, leading to a poor user experience, and users cannot be notified of new messages when Instant Session Barring is set, resulting in inconvenience and underutilization of resources.
Innovation Solution
A method and apparatus that determine the session type to prevent voice prompts in one-to-many sessions and send text notifications to users with Instant Session Barring enabled, allowing timely message delivery through a PoC service server with communication, control, determination, and processing modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice mailbox plays voice prompt for each user in one-to-many session, then voice mailbox function is provided, but user experience deteriorates due to time-consuming and annoying voice prompt playback
Solution Approach 1:
The patent changes the notification parameter from voice prompt to text message in one-to-many sessions. The server detects the session type and switches the notification method, eliminating the need for repetitive voice prompt playback while still notifying users of new messages efficiently.
Solution Approach 2:
Instead of playing voice prompts to notify users of new messages (conventional approach), the patent inverts the approach by sending text messages to notify users. This inversion resolves the contradiction by providing notification functionality without the time-consuming and annoying voice prompt playback.
2Reliability
If direct telephone call method is used for voice message notification, then voice message can be delivered, but user cannot be notified when Instant Session Barring is set
Solution Approach 1:
The patent introduces an intermediary notification mechanism (text message) between the voice mailbox system and the user. When Instant Session Barring is set, the text message acts as a mediator to notify the user of new messages without requiring a direct telephone call, thus maintaining notification reliability while adapting to the user's barring setting.
Solution Approach 2:
The patent changes the notification parameter from telephone call to text message when Instant Session Barring is detected. This parameter change allows the system to maintain message delivery reliability while adapting to users who have configured session barring, solving the contradiction between reliability and adaptability.
3Reliability
If voice message reception via telephone call is required, then voice message can be received, but user convenience deteriorates and PoC service resources are underutilized
Solution Approach 1:
The patent substitutes the mechanical telephone call system with a text-based notification system for informing users of new messages. Users receive text notifications and can then choose to access their voice mailboxes at their convenience, eliminating the requirement to answer incoming calls while maintaining reliable message reception capability.
Solution Approach 2:
The patent introduces text message notification as an intermediary between the voice mailbox system and the user. This intermediary allows users to be informed of new messages without being forced into telephone calls, improving convenience while maintaining the ability to receive voice messages when users choose to access their mailboxes.

AI summary
A method of providing a voice mailbox function in a PoC service, including: if the voice mailbox of at least one called user is to be connected in response to receiving a session establishment request from a calling user, determining whether the session corresponding to the session establishment request is a one-to-many session; and recording a message from the calling user through the voice mailbox if the session is a one-to-many session. The invention further discloses a method in a PoC service of notifying of a message in a voice mailbox, and a PoC service server.
