Cross-mobile Network Operator Server for Service Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Application and Media Service Providers face challenges in reaching all subscribers across different IP networks, fixed and mobile, due to the complexity of establishing service level agreements with multiple network operators and adapting service offerings to each operator's unique APIs.
Innovation Solution
A method and system for a communication device to discover network services by signaling requests through a server to resolve or redirect fully qualified domain names (FQDNs) to internet protocol (IP) addresses, allowing access to network features without requiring individual agreements with each mobile network operator, using DNS resolution and HTTPS redirection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Application Service Providers establish individual service level agreements with each network operator, then service reliability is improved, but device complexity and operational burden increase significantly
Solution Approach 1:
The patent introduces a service level agreement server as an intermediary that centralizes the management of service level agreements between application service providers and multiple network operators. Instead of establishing individual agreements with each operator, the ASP interacts with a single server that handles multiple operators, thereby reducing complexity while maintaining service reliability through standardized agreement management
2Adaptability or versatility
If Application Service Providers adapt service offerings to each individual network operator's APIs, then service adaptability is improved, but manufacturing precision and development time increase
Solution Approach 1:
The patent creates a universal service level agreement server that works with multiple network operators through standardized interfaces. The server provides multi-functional capabilities by handling different operators' APIs through a common framework, allowing application service providers to adapt to various operators without developing separate integration solutions for each, thus maintaining adaptability while reducing configuration precision requirements
Solution Approach 2:
The system enables parameter changes by allowing the service level agreement server to dynamically adjust configuration parameters based on the specific network operator being accessed. This allows the same universal interface to adapt to different operators by changing operational parameters rather than structural design, maintaining service adaptability while simplifying the development process
3Adaptability or versatility
If Application Service Providers negotiate service level agreements with multiple network operators, then service coverage is improved, but loss of time and operational efficiency decrease
Solution Approach 1:
The patent implements preliminary action by pre-establishing service level agreement templates and configurations in the centralized server before actual service deployment. Network operators and application service providers can agree on standardized terms in advance, and the server stores these pre-configured agreements, eliminating the need for time-consuming negotiations each time a new service is deployed across multiple operators

AI summary
A method performed by a communication device in a network comprising mobile networks operated by mobile network operators, MNOs, is provided. The method includes signaling to a first server to discover a second server having information about a public land mobile network identifier and a network service of a MNO. The second server has a first fully qualified domain name, FQDN, pointing to a provider domain. The method further includes receiving a response including a resolution or a redirection of the FQDN; signaling to discover the information about the network service; and receiving a response from the second server including a first identification of the information about the network service of the MNO or a second identification that the network service is not available. Corresponding methods performed by a first server and a second server are also provided.
