IP Short Message Gateway SCCP Address Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Incompatibilities in messaging formats between second, third, and fourth generation wireless communication protocols, particularly between IP-based and non-IP-based networks, result in information loss during message translation, limiting the utilization of addressing information for service providers.
Innovation Solution
A computer-implemented method and system utilizing an IP short message gateway with multiple SCCP addresses to identify and transform messages between IP and non-IP networks, ensuring differentiated handling and accurate delivery of short messages by using SCCP addresses corresponding to IP addresses, thereby preserving addressing information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If message translation is performed between IP-based and non-IP-based communication protocols, then interoperability between different wireless communication protocols is improved, but addressing information is lost during the translation process
Solution Approach 1:
The patent introduces an IP Short Message Gateway as an intermediary component that sits between the IP-based network and non-IP-based network. This gateway performs message translation while preserving addressing information by maintaining a mapping between IP addresses and traditional messaging format addresses. The gateway acts as a mediator that enables interoperability without sacrificing the addressing information needed for billing, authorization, and security purposes.
2Ease of operation
If traditional message translation components are used, then message delivery between different protocols is enabled, but the complexity of the system increases due to information loss requiring additional mediation
Solution Approach 1:
The IP Short Message Gateway is designed to perform multiple functions simultaneously: it translates messages between different protocols, preserves addressing information, enables differentiated services based on network information, and supports billing and authorization. By consolidating these functions into a single multi-functional component, the system achieves ease of message delivery without proportionally increasing complexity.
3Ease of manufacture
If addressing information is lost during translation, then simplified message format conversion is achieved, but the ability to provide differentiated services and accurate billing is reduced
Solution Approach 1:
The system performs preliminary action by preserving addressing information during the message translation process. Instead of simply converting formats and losing addressing data, the gateway proactively maintains the association between IP addresses and traditional addressing formats. This preliminary preservation of information enables subsequent differentiated services, billing, and authorization functions to operate effectively.

AI summary
An IP short message gateway (IP-SM-GW) utilizes multiple addresses for delivering short messages between an IP network and a cellular network. The IP short message gateway can have multiple SCCP addresses that correspond to categories of origin/destination IP addresses of short messages. In response to a request to deliver a short message between an IP network and a cellular network, the IP short message gateway identifies an IP address associated with the origin/destination of the short message. The IP short message gateway then identifies at least one of its multiple SCCP addresses based on the identified IP address. The IP short message gateway can generate a response message that includes the identified SCCP address. The identified SCCP address in the response message will be available to SMSC or IMS. SMSC or IMS can implement differentiated handling of short messages based on SCCP addresses received from the IP short message gateway.
