Wireless Messaging Bearer Selection for High-Capacity Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing messaging services, such as SMS, EMS, and MIM, are limited by data capacity, require registration, and lack flexibility in message delivery based on recipient capabilities.
Innovation Solution
A method and system that combines SMS, EMS, and MIM to provide a unified messaging interface, dynamically selecting the bearer type based on recipient capabilities and status, allowing text, voice, and multimedia messaging without requiring user registration, and enabling automatic configuration and peer-to-peer subscription.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SMS protocol is used for message delivery, then message delivery reliability is improved, but data capacity is limited to 160 characters
Solution Approach 1:
The system dynamically selects between SMS bearer and packet-switched data bearer based on message characteristics and recipient capabilities. For text-only messages under 160 characters, SMS protocol is used for reliable delivery. For messages exceeding this limit or requiring multimedia, the system automatically switches to packet-switched data bearer, providing flexible adaptation to different data capacity requirements while maintaining delivery reliability.
2Quantity of substance
If MIM service is used for instant messaging, then message capacity and multimedia support are improved, but user registration and persistent connection requirements increase system complexity
Solution Approach 1:
The invention extracts the registration and persistent connection requirements from the messaging system by using SMS-based authentication and stateless architecture. Users authenticate via SMS protocol without registering with the system, and the server maintains no persistent connections, eliminating the complexity associated with MIM services while still enabling instant messaging functionality.
Solution Approach 2:
The system enables peer-to-peer messaging where the recipient initiates communication by sending an SMS to a shortcode, automatically triggering the sender's client to establish a data connection and begin messaging. This self-service approach eliminates the need for manual registration and connection setup, reducing system complexity while maintaining full messaging capabilities.
3Quantity of substance
If EMS protocol is used to package multiple messages, then message content richness is improved, but compatibility with basic SMS infrastructure limits versatility
Solution Approach 1:
The system implements a universal messaging interface that can handle multiple message types (text, multimedia, voice) through a single packet-switched data bearer, while also maintaining compatibility with basic SMS infrastructure for text-only messages. The system automatically adapts the message delivery method based on content requirements, providing both richness and versatility without requiring separate protocols for different message types.

AI summary
A method performed by a mobile wireless device may comprise receiving an SMS message or an EMS message indicating a client program, when a phone number associated with the mobile wireless device is not associated with a subscriber of a service associated with the client program at the time of receiving the SMS message. The method may further comprise downloading the client program on the mobile wireless device and authenticating, via the client program, the phone number associated with the mobile wireless device to the service via SMS protocol. After the authenticating, the client program may cause transmission of first information comprising a first phone number. The client program may receive a first response to the transmission of the first information indicating that the first phone number is associated with a subscriber of the service.
