SMS Forwarding Service Node in GSM UMTS Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for forwarding short messages in GSM/UMTS networks require significant resource expenditure due to the need for changes in network elements and interfaces, making them costly and time-consuming to implement.
Innovation Solution
A method utilizing standardized ITU-T interfaces and a separate service node with modular function blocks for interaction, translation, and accounting, allowing seamless integration into existing GSM/UMTS networks without altering existing voice profile data or charging systems, and enabling unconditional SMS forwarding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing methods for forwarding short messages are implemented, then SMS forwarding functionality is achieved, but significant resource expenditure is required due to changes in network elements and interfaces
Solution Approach 1:
The patent introduces a service node as an intermediary component that mediates between the SMS center and the home location register. This service node intercepts SMS routing requests, performs number translation to determine forwarding destinations, and manages forwarding logic separately from the core network elements. By placing this intermediary layer, the patent enables SMS forwarding functionality without requiring modifications to existing network elements such as the SMS center or HLR, thus resolving the contradiction between achieving forwarding capability and avoiding complex network changes.
2Ease of manufacture
If standardized interfaces are used, then integration into existing GSM/UMTS network is seamless and cost-effective, but implementation requires separate service node
Solution Approach 1:
The service node is segmented into distinct functional modules: an interaction function that communicates with network elements using standardized interfaces, a translation function that performs number translation for forwarding, and an accounting function that handles charging. This segmentation allows each module to be developed, deployed, and maintained independently while working together through well-defined interfaces. The modular architecture reduces integration complexity with the existing network by standardizing external communications while containing the complexity within the service node itself, resolving the contradiction between ease of integration and service node complexity.

AI summary
The invention relates to a method and a device for forwarding short messages from a transmitter (24) to a target number of a receiver (26) in GSM/UMTS mobile radio networks, wherein the target number of the receiver (26) is replaced by a forwarding call number before establishing routing information required for delivery of the short message in a service node (10) and delivery of the short message to the forwarding call number is carried out.
