WAP Push via Cell Broadcast URL Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional GSM systems are limited in their ability to broadcast services beyond text messages, preventing the transmission of Wireless Application Protocol (WAP) messages and Multimedia Messaging Service (MMS) information via cell broadcast, which restricts the amount of information that can be conveyed and reduces the usefulness of cell broadcast functionality.
Innovation Solution
A system that utilizes predetermined cell broadcast channels to send Uniform Resource Locators (URLs) to mobile stations, enabling the delivery of multimedia and rich content through Wireless Access Protocol (WAP) push operations without individual addressing, allowing wireless carriers to provide geographically-targeted content to multiple mobile stations simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional cell broadcast is used to send messages, then all clients receive the broadcast message, but only text messages can be transmitted and additional information such as WAP messages or MMS information cannot be conveyed
Solution Approach 1:
The patent embeds WAP push messages and MMS information within the cell broadcast message structure. The broadcast message contains a URL that links to additional multimedia content, effectively nesting rich content delivery within the conventional text-based broadcast framework. This allows the system to convey both text and multimedia information through a single broadcast mechanism.
Solution Approach 2:
The patent introduces a URL as an intermediary element within the cell broadcast message. Instead of directly transmitting multimedia content in the broadcast, the message contains a URL that directs clients to retrieve additional information. This intermediary approach enables the transmission of rich content while maintaining compatibility with the existing text-based broadcast infrastructure.
2Productivity
If individual addressing is used to send WAP push messages to mobile stations, then specific messages can be delivered to specific devices, but the system cannot efficiently broadcast to large numbers of mobile stations in a geographic area
Solution Approach 1:
The patent makes the cell broadcast channel universal by enabling it to carry both traditional text messages and WAP push messages with multimedia content. The same broadcast infrastructure is used for both individual addressing and geographic broadcasting, eliminating the need for separate systems. The broadcast message structure is designed to accommodate multiple message types and content formats, providing multi-functionality to the communication system.
3Quantity of substance
If conventional cell broadcast channels are used, then broadcast messages can be sent to all clients, but the channels cannot convey multimedia and rich content
Solution Approach 1:
The patent segments the content delivery into two parts: the cell broadcast message contains the essential text information and a URL, while the multimedia and rich content are separated and stored at the location indicated by the URL. This segmentation allows the broadcast channel to transmit concise messages while the actual rich content is delivered through a different channel (data network), reducing the complexity of the broadcast message structure while still conveying abundant information.
Data Source
AI summary
A system provides push services and information to mobile stations via broadcast messages. The broadcast messages are made on predetermined cell broadcast channels, which are associated with an inbox on the mobile stations. Contained within the messages are Uniform Resource Locators (URL) that, when accessed, provide multimedia and other rich content to the mobile station. The system allows wireless carriers to provide features such as Wireless Access Protocol (WAP) push operations via cell broadcast to many mobile stations in a geographic area without the need to individual address messages to the mobile stations.
