Remote Administration via Signaling Network Session Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote management of devices in private communication networks, particularly those without a public universal address, faces challenges in session establishment due to the complexity of existing methods requiring updates to both gateways and local network devices, making it difficult to trigger session establishments effectively.
Innovation Solution
A method that allows devices in private communication networks to initiate session establishment by sending a connection request via a signaling network separate from the access network, using a contact number, which simplifies the process and does not require modifications to the access gateway, only updating the device and administration equipment software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods (STUN or UPnP-IGD) are used to transmit connection requests for devices on private networks, then session establishment can be achieved, but the implementation becomes complex and requires updates to both gateways and local network devices
Solution Approach 1:
The patent extracts the connection request transmission from the access network path and relocates it to the signaling network path. By separating these functions, the complex gateway translation mechanisms (STUN/UPnP) are eliminated, and only the terminal device and administration equipment need updates, significantly reducing overall system complexity while maintaining reliable session establishment
Solution Approach 2:
The patent introduces the signaling network as an intermediary channel for transmitting connection requests. This mediator bypasses the need for complex gateway interventions in the access network, allowing direct communication between administration equipment and terminal devices while simplifying the overall architecture
2Ease of operation
If a public universal address is assigned to mobile devices on private networks, then connection requests can be transmitted via the access network, but mobile network operators typically do not assign public addresses to mobile devices
Solution Approach 1:
The patent makes the signaling network serve multiple functions: it not only handles traditional signaling messages but also transports connection requests for session establishment. This multi-functional approach allows the system to work universally across different network types (mobile and fixed) without requiring public address assignment, enhancing both ease of operation and network adaptability

AI summary
The invention concerns a technique for remote administration, by an administration apparatus (41), of a device (30-37) belonging to a private communication network (3). The device sends administration data to the administration apparatus via an access network, said administration data comprising a first item of connection data and a contact number associated with the device in a signalling network. In order to administer the device, the administration apparatus sends a connection request to the device via the signalling network by means of the received contact number. This connection request triggers the establishment of a session by the device with the administration apparatus via the access network.
