SIP Registrar Credential Segmentation for MMS Service Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless and wireline networks fail to adequately address the data transfer requirements of multimedia capable devices, particularly in denying or terminating Multimedia Messaging Service (MMS) requests effectively on Session Initiation Protocol (SIP) and IP multimedia subsystem (IMS) networks.
Innovation Solution
A method and system for denying or terminating MMS requests on SIP-based networks, involving an SIP registrar and MMS server that receive and process registration and service requests, determining whether to deny or terminate services based on credential information and network conditions, and providing corresponding responses to users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing networks allow users to exchange simple text based messages and support multimedia applications, then network functionality and service capability are improved, but network complexity and difficulty of managing service requests increase
Solution Approach 1:
The patent segments the service request handling process into distinct phases: registration phase (where credentials are verified) and service request phase (where actual MMS requests are processed). The SIP registrar handles registration and credential verification separately from the MMS server that processes actual messaging requests. This segmentation allows the network to support complex multimedia services while managing complexity through structured, modular handling of different request types.
2Adaptability or versatility
If application servers are introduced to support multimedia applications, then service capability is improved, but system complexity and difficulty of service management increase
Solution Approach 1:
The patent implements preliminary credential verification through the SIP registrar before MMS service requests are processed. During the registration phase, user credentials are authenticated and stored in advance. When actual MMS requests arrive at the MMS server, the credential checking has already been performed, allowing the service server to focus solely on processing multimedia messaging requests without re- verifying credentials. This preliminary action reduces system complexity by separating authentication from service processing.
3Reliability
If credential verification is performed for each service request, then service security is improved, but processing time and system response time worsen
Solution Approach 1:
The patent performs credential verification in advance during the SIP registration phase, storing authenticated credential information for later use. When MMS service requests are processed, the system references pre-verified credentials rather than re-authenticating each request. This preliminary credential verification maintains service security while significantly reducing processing time for actual MMS operations.
Solution Approach 2:
The system enables self-service by caching authenticated credential information from the registration phase, allowing the MMS server to independently verify service requests using pre-stored credential data without requiring continuous intervention from the SIP registrar or repeated authentication processes. This self-service mechanism maintains security while improving processing efficiency.

AI summary
A method and system are provided for denying an application service request, such as a Multimedia Messaging Service (MMS) request, on wireless and wireline Internet Protocol (IP) Multimedia Subsystem (IMS) networks or Session Initiation Protocol (SIP) networks. In one example, the method includes receiving a request for an application service from a user via a transport network, determining to deny the request, and providing a response corresponding to the denial of the request to the user via the transport network.
