Dual Path Messaging System for Attachment Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless packet data service networks face challenges in efficiently forwarding large message attachments over low-bandwidth communication paths, which can lead to delayed or inconvenient delivery of attachments to mobile communication devices.
Innovation Solution
The system employs a dual wireless data path approach, where a primary low-cost, low-bandwidth path is used for standard communication, and a secondary high-bandwidth path, potentially a virtual private network, is established only when necessary for transmitting large attachments, allowing for secure and efficient delivery of attachments directly to mobile communication devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If message attachments are transmitted over the primary low-bandwidth wireless data path, then network infrastructure costs are reduced, but transmission speed and delivery time deteriorate
Solution Approach 1:
The system dynamically selects between two wireless data paths based on attachment size thresholds. For small attachments, the primary low-bandwidth path is used to save costs. For large attachments exceeding the threshold, the system automatically establishes a secondary high-bandwidth path, making the transmission path adaptive rather than static.
Solution Approach 2:
The invention changes the bandwidth parameter of the transmission path based on the attachment size parameter. By monitoring attachment size and comparing it against a predetermined threshold, the system transitions between different transmission modes (primary path vs. secondary path), effectively using parameter changes to resolve the contradiction between cost and speed.
2Productivity
If a secondary high-bandwidth wireless data path is established for large attachments, then transmission efficiency improves, but system complexity increases
Solution Approach 1:
The message relay server acts as an intermediary that manages the complexity of dual path coordination. It receives messages, determines attachment size, decides which path to use, and coordinates between the primary and secondary paths. This centralizes the complexity management and prevents the mobile device from bearing the full burden of path management complexity.
Solution Approach 2:
The transmission system is segmented into two independent paths with distinct functions. The primary path handles control signaling and small attachments, while the secondary path is dedicated to large attachment transfers. This segmentation allows each path to be optimized independently and simplifies the overall management by clearly defining responsibilities.
3Quantity of substance
If the secondary data path is established only when needed, then network resource utilization optimizes, but path establishment time is added
Solution Approach 1:
The system performs preliminary assessment of attachment size before transmission begins. By evaluating the attachment size threshold condition in advance, the system can proactively establish the secondary path before actual data transfer starts, preventing delays during the transmission process itself.
Solution Approach 2:
For large attachments that require the secondary path, the system rushes through the path establishment process by prioritizing the setup of high-bandwidth connection when needed. The predetermined threshold triggers immediate activation of the secondary path mechanism, skipping unnecessary delays in path selection and establishment.
