SMS Proxy Gateway for WLAN Interworking and Capability Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current architectures for supporting Short Message Service (SMS) over Wireless Local Area Networks (WLANs) do not effectively cover control signaling associated with SMS, limiting the functionality of SMS proxy in IP-based systems.
Innovation Solution
The SMS proxy function in the SMS IP gateway extracts SMS data messages from SS7/MAP format and sends them to interworking WLAN user equipment using IP-based protocols, acting as a terminal front end to determine and manage the capabilities of the user equipment for efficient SMS message delivery and sending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If SMS proxy acts as terminal front end to SS7/MAP, then SMS data message delivery is enabled over IP, but control signaling coverage is incomplete
Solution Approach 1:
The patent introduces an SMS gateway as an intermediary component that bridges the SS7/MAP network and IP-based networks. The gateway performs protocol conversion, extracting SMS data messages from SS7/MAP format and transmitting them over IP protocols to WLAN user equipment. This intermediary approach enables SMS delivery over IP while maintaining compatibility with existing SS7 infrastructure, resolving the contradiction between enabling IP-based delivery and ensuring reliable control signaling coverage.
2Adaptability or versatility
If SMS proxy extracts SMS data from SS7/MAP format, then IP-based protocol transmission is achieved, but functionality coverage is limited
Solution Approach 1:
The patent segments the SMS gateway functionality into distinct components: an SS7/MAP interface for receiving traditional SMS messages, a protocol conversion module for extracting and transforming message data, and an IP interface for transmitting converted messages to WLAN devices. This segmentation allows the system to handle protocol conversion and message delivery separately, reducing overall system complexity while maintaining comprehensive functionality across different network protocols.

AI summary
A method for delivering a short message service (SMS) message to an interworking wireless local area network user equipment (UE) begins by registering the UE with an Internet Protocol short message gateway (IP-SM-GW). A capability report is sent from the UE to the IP-SM-GW, the capability report including the capabilities of the UE. A SMS message is transmitted from a short message service center (SMSC) to the IP-SM-GW. The capabilities of the UE are evaluated at the IP-SM-GW to determine whether the UE can receive the SMS message, and the SMS message is delivered to the UE via the IP-SM-GW if the UE has the capabilities to receive the SMS message.
