Network Data Delivery by Session-Aware Control Plane Signalling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for selecting data transmission modes in mobile networks, such as those in 4G and 5G, are inefficient in managing network resources and require difficult adaptations in mobile terminals, especially when connecting devices to private networks without pre-configured authentication information.
Innovation Solution
A method that detects the receipt of a data request from a user equipment and monitors the establishment of a session within a predetermined time period, opting for user plane transmission if a session is established before the time expires, and control plane transmission if not, using signaling messages to deliver data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the network systematically transmits low-volume data in the control plane, then network resource management is simplified, but this is not always the optimum solution when the mobile terminal is already connected via user plane
Solution Approach 1:
The patent applies dynamics by making the transmission mode selection adaptive rather than static. The network dynamically chooses between control plane and user plane based on real-time conditions, specifically whether a user plane session is already established. This resolves the contradiction by allowing the system to simplify management when appropriate while maintaining optimal resource utilization when user plane connectivity exists.
2Reliability
If the mobile terminal indicates its preference between transmission modes, then transmission optimization is achieved, but this requires difficult adaptation in mobile terminals
Solution Approach 1:
The patent inverts the traditional approach by having the network make the transmission mode decision based on network-side observations (whether a user plane session is established) rather than relying on terminal preferences. This inversion eliminates the need for complex terminal adaptations while still achieving optimized transmission, as the network autonomously selects the appropriate mode based on actual connectivity state.
3Productivity
If authentication information is transmitted via user plane, then data transmission efficiency is improved, but this requires pre-establishment of a PDU session and IP connectivity
Solution Approach 1:
The patent applies preliminary action by having the network prepare and transmit authentication information in advance via the control plane before the user plane session is fully established. This allows the terminal to receive necessary authentication data without waiting for complex user plane setup, thereby reducing the overall time required for connection establishment while maintaining the efficiency benefits of user plane data transmission.
4Reliability
If the network waits for user plane session establishment before transmitting data, then data transmission reliability is improved, but this increases the time delay for authentication information delivery
Solution Approach 1:
The patent applies preliminary action by transmitting authentication information via the control plane before the user plane session is established. This preliminary transmission of critical authentication data eliminates the time delay that would otherwise occur while waiting for user plane setup, while still maintaining reliability by using the established control plane connection for this initial data transfer.
Data Source
AI summary
A method for transmitting data from a communication network to an item of user equipment. The method includes: detecting reception of a request to obtain data, sent by the item of user equipment; monitoring whether a session with the item of user equipment through the communication network is established following the detection of the reception of said request; and if no establishment of a session with the item of user equipment is detected before expiration of a period after the detection of the reception of the request, transmitting, to the item of user equipment, at least one signalling message containing the data. Also provided are a network entity, a corresponding system and item of user equipment.
