SCS Serving Node Routing for MTC Small Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mechanisms in mobile networks, such as 3GPP-based networks, are less optimal for handling small data transmissions in machine-to-machine or machine-to-human applications, leading to inefficiencies in communication services for devices like smart meters and consumer products.
Innovation Solution
The system determines routing for short messages by sending a first routing request to a Home Subscriber Server (HSS) with an MTC indicator field, receiving a control plane routing reply, and subsequently sending the message to a Service Capability Server (SCS) serving node, which includes an MTC-IWF address, and further requests from the SCS subscription database for gateway and application protocol information.

Engineering Contradiction Analysis
1Productivity
If traditional 3GPP network mechanisms are used for small data transmission, then network compatibility is maintained, but transmission efficiency and reliability deteriorate
Solution Approach 1:
The patent introduces an SCS serving node as an intermediary component between the SMS-SC and the ultimate data destination. This intermediary specializes in handling MTC small data transmissions, providing optimized routing and transmission mechanisms that improve both efficiency and reliability while maintaining compatibility with existing 3GPP network structures.
Solution Approach 2:
The patent segments the traditional monolithic SMS handling process into distinct components: the SMS-SC for initial message reception, the SCS serving node for specialized MTC data handling, and the HSS for subscriber information management. This segmentation allows each component to be optimized for its specific function, improving overall transmission efficiency.
2Productivity
If optimized routing for MTC devices is implemented, then transmission efficiency improves, but system complexity increases
Solution Approach 1:
The SCS serving node is designed with multi-functionality, handling both traditional SMS routing and optimized MTC small data transmission. By consolidating these functions in a single node, the system achieves improved routing efficiency for MTC devices without proportionally increasing overall system complexity.
Solution Approach 2:
The system implements self-service mechanisms where the SCS serving node automatically determines optimal routing paths for MTC devices based on subscriber information from the HSS. This automated routing decision-making reduces the need for complex manual configuration and management of routing rules.

AI summary
Systems, methods, and instrumentalities are provided to determine routing associated with a short message. A SMS-SC may send a first routing request to a home subscriber server (HSS). The first routing request may be associated with the short message. The SMS-SC may receive a first routing reply. The first routing reply may include one of an indication that the short message is associated with a service capability server (SCS) or a first control plane routing associated with the short message. The SMS-SC may send the short message to an SCS serving node. The first routing reply may include the indication that the short message is associated with a service capability server (SCS). The SMS-SC may send a second routing request to a SCS subscription database. The SMS-SC may receive a second routing reply from the SCS subscription database, which may indicate a second control plane routing for the short message.
