Control Plane Signaling Message Type Identification for M2M Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In M2M communication, user plane data is often lost during transmission through control plane signaling due to the inability of network nodes to distinguish between conventional and user plane data-containing control plane signaling, leading to network congestion and resource wastage.
Innovation Solution
A method is introduced where a message type identification is set in control plane signaling, allowing network nodes to identify and transmit user plane data to appropriate equipment or servers, ensuring correct processing and reducing congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If control plane signaling is used to transmit user plane data in M2M communication, then network resource utilization is improved, but network nodes cannot distinguish between conventional and user plane data-containing signaling, causing data loss
Solution Approach 1:
The patent introduces a message type identification field (analogous to a 'color' or label) in the control plane signaling that explicitly indicates whether the signaling contains user plane data or not. This identification mechanism allows network nodes to distinguish between different types of control plane signaling, preventing data loss while maintaining efficient resource utilization.
2Adaptability or versatility
If M2M communication is supported in the current mobile network, then service coverage is improved, but network congestion and resource wastage increase due to large quantities of signaling
Solution Approach 1:
The patent combines user plane data with control plane signaling transmission, allowing small data to be carried within the existing control plane message structure. This merging eliminates the need for separate data transmission channels for small data, reducing overall signaling quantity and preventing network congestion while maintaining broad service coverage.
3Ease of operation
If conventional control plane signaling processing is used, then processing simplicity is maintained, but user plane data is lost because nodes process all signaling identically
Solution Approach 1:
The patent segments control plane signaling into distinct types by introducing a message type identification field. This segmentation allows network nodes to differentiate between conventional signaling and signaling containing user plane data, enabling appropriate processing for each type while maintaining overall processing simplicity through standardized identification mechanisms.

AI summary
The present invention discloses a method for indicating a message type, including: setting a message type identification in a transmitted control plane signaling; a network node which receives the control plane signaling, according to the message type identification, identifying whether user plane data are contained in the control plane signaling, and transmitting the user plane data to a user equipment or other network nodes or a machine type communication server (MTC Server) through the control plane signaling when confirming that the control plane signaling contains the user plane data; and the user equipment or the MTC Server identifying whether the control plane signaling contains the user plane data, and retrieving the user plane data therefrom when the control plane signaling contains the user plane data. The present invention further provides a system and apparatus for indicating a message type. According to the technical scheme of the present invention, it can solve the problem that the user plane data are lost when the control plane signaling contains the user plane data.
