Voice Mail Server Caching for Network Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice mail systems in telecommunications face inefficiencies in processing voice mail messages due to limitations in network architecture, leading to resource consumption and hindered growth in messaging capabilities.
Innovation Solution
A method for delivering voice mail messages that involves determining the content and recipient, converting the message to formats like text or email, and caching voice mail box information for efficient delivery, utilizing LDAP and DNS servers to optimize network utilization and response times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If voice mail messages are processed using traditional circuit switched networks, then voice mail delivery is achieved, but network resources are consumed inefficiently and response times are slow
Solution Approach 1:
The patent replaces the traditional circuit switched network architecture with a packet switched network architecture. Instead of establishing dedicated circuit connections for voice mail delivery, the system uses IP-based packet switching to transport voice mail messages efficiently across the network, reducing resource consumption and improving scalability
Solution Approach 2:
The patent changes the network operating mode from circuit switched to packet switched, and introduces caching mechanisms that store voice mail box information locally. This parameter change in information availability and network protocol enables asynchronous message delivery, improving processing efficiency and reducing real-time network resource demands
2Loss of time
If voice mail box information is retrieved from LDAP or DNS servers for each delivery, then accurate routing is achieved, but response times are slow due to repeated queries
Solution Approach 1:
The patent implements a caching mechanism that pre-loads and stores voice mail box information from LDAP or DNS servers into local cache memory. This preliminary action ensures that routing information is readily available when messages need to be delivered, eliminating the need for repeated server queries and significantly reducing response times
Solution Approach 2:
The patent creates local copies of voice mail box information from the centralized LDAP or DNS servers. These cached copies are stored locally at the voice mail server, allowing rapid access and comparison operations without requiring continuous communication with the original servers, thus speeding up message delivery
3Adaptability or versatility
If visual voice mail is delivered to multiple recipients, then messaging capability grows, but processing complexity increases due to content analysis and format conversion requirements
Solution Approach 1:
The patent segments the voice mail processing workflow into distinct modular components: content analysis module, recipient identification module, format conversion module, and delivery module. Each component handles a specific aspect of the processing, making the overall complex system manageable and allowing parallel processing of multiple messages to different recipients
Solution Approach 2:
The patent introduces an intermediary voice mail server that acts as a mediator between the calling party and multiple called parties. This server performs content analysis, determines appropriate recipients based on message content, converts messages to suitable formats, and manages delivery to multiple recipients, thereby simplifying the complexity for individual devices
Data Source
AI summary
A method for delivery of a voice mail message to a recipient. The method includes determining content of the voice mail message, identifying a recipient of the voice mail message based on the determining step, converting the voice mail message to a format for delivery based on the identifying step, and delivering the converted voice mail message to the recipient. The method further includes identifying a voice mail box of the recipient and caching voice mail box information at a voice mail server.
