Service Delivery Platform Protocol Translation for Legacy Network Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to enable legacy applications to interact with next generation networks, leading to costly and time-consuming modifications, which hinders the adoption of new network technologies.
Innovation Solution
A Service Delivery Platform (SDP) is used to translate communications between legacy and next generation networks, allowing legacy applications to interact by receiving communications in one protocol and converting them to another based on the communication session state, using components like SIP servlets and IP Multimedia Service Control/ Switching Functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If legacy applications are modified to operate on next generation networks, then compatibility with new networks is improved, but cost and time consumption increase
Solution Approach 1:
The patent introduces a Service Delivery Platform (SDP) as an intermediary component that sits between legacy applications and next generation networks. The SDP performs protocol translation and session state management, allowing legacy applications to interact with next generation networks without modification. This mediator approach resolves the contradiction by maintaining legacy application compatibility while enabling next generation network access, avoiding the costly and time-consuming modification process.
2Adaptability or versatility
If legacy applications are replaced with new applications, then compatibility with next generation networks is improved, but implementation cost and time increase
Solution Approach 1:
The patent creates a virtual copy or representation of legacy applications through the Service Delivery Platform. The SDP maintains the functional behavior and interface of legacy applications while translating their communications to next generation network protocols. This copying approach allows legacy applications to continue operating unchanged while gaining access to next generation networks, eliminating the time-consuming replacement and implementation process.
3Adaptability or versatility
If protocol translation is implemented, then interaction between legacy and next generation networks is enabled, but system complexity increases
Solution Approach 1:
The patent merges multiple translation functions and session management capabilities into a single integrated Service Delivery Platform. Rather than implementing separate translation components for each legacy application, the SDP consolidates protocol translation, session state management, and network interface functions into one unified system. This merging approach enables network interaction capability while reducing overall system complexity through functional integration and shared resources.

AI summary
Embodiments of the invention provide systems and methods for allowing legacy applications to interact with new networks. According to one embodiment, a method for supporting interactions and services between a legacy network and a next generation network can comprise receiving at a service layer component a communication in a communication session from a first communication network. The communication can be in a first protocol. The communication can be translated from the first protocol to a second protocol with the service layer component based on the state of the communication session. The first protocol can be different from the second protocol.
