Adapting Information Content via Access Bearer Capability Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack the ability to identify and adapt to the capabilities of different radio access bearers, leading to inefficient information transmission and user experience issues due to unknown bearer types and varying costs.
Innovation Solution
The system recognizes and forwards the capability information of the access bearer to the application server, allowing it to tailor content according to the bearer's characteristics, such as transmission speed, by attaching this information to request messages and using specialized WAP Gateways for each access type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system uses multiple types of radio access bearers with different transmission speeds, then the user can access information through various channels, but the application server cannot identify the bearer type leading to inefficient information transmission
Solution Approach 1:
The patent introduces a WAP gateway as an intermediary component between the mobile station and the application server. The gateway detects the access bearer type (SMS, CSD, GPRS, UMTS, Bluetooth) and forwards this capability information to the application server, enabling the server to adapt its information transmission to match the bearer's capabilities without requiring the server to directly detect or know the bearer type.
Solution Approach 2:
The system implements a feedback mechanism where the WAP gateway continuously monitors the access bearer type and transmits this capability information back to the application server. This feedback loop allows the server to dynamically adjust its information delivery strategy based on the current bearer capabilities, ensuring optimal transmission efficiency across different radio access types.
2Adaptability or versatility
If the application server transmits information designed for high-speed bearers (CSD 9.6 Kbps) through low-speed bearers (SMS), then the system maintains compatibility with all access types, but the download time becomes too long and inconvenient for users
Solution Approach 1:
The application server uses the received bearer capability information to dynamically change transmission parameters such as information format, size, and compression level. When detecting SMS bearer (low speed), the server transmits simplified, compressed content. When detecting CSD or GPRS (high speed), the server transmits full-resolution content, thereby optimizing download time for each bearer type while maintaining universal compatibility.
3Productivity
If the system attaches capability information to request messages and uses specialized WAP Gateways for each access type, then the information transmission is optimized for the bearer capability, but the system complexity increases
Solution Approach 1:
The WAP gateway is designed as a universal multi-functional component that can handle multiple bearer types (SMS, CSD, GPRS, UMTS, Bluetooth) through a single standardized interface. Rather than requiring separate specialized gateways for each bearer type, the universal gateway detects the bearer type and applies appropriate capability information, reducing overall system complexity while maintaining optimized transmission for each access type.
Data Source
AI summary
A communication system is adapted to provide access to application information on an application server utilizing a specific one of multiple radio access types. Access is provided via an access network using an access bearer. The capability of the specifically requested access bearer is sent to the application server to tailor the application information content according to the capability of the specific access bearer. The information content is then transmitted to the requesting device.
