NB-IoT Access Network Device Service Data Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication technologies for Narrowband Internet of Things (NB-IoT) cannot provide targeted services due to the inability to differentiate and manage service data transmitted using Non-Access Stratum (NAS) signaling messages, leading to inefficient resource allocation and service delivery.
Innovation Solution
A method and device configuration that determine and transmit service data information, including service type and priority, to enable targeted charging and resource management, allowing the network to differentiate and manage NB-IoT services effectively by using an access network device and mobility management entity to allocate resources and charge services based on the received information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If service data is transmitted using NAS signaling message, then transmission resource waste is avoided, but network side cannot provide targeted services
Solution Approach 1:
The patent introduces an intermediary mechanism by embedding service data information (service type and priority) within the NAS signaling message structure. This allows the network side to extract and process service identification information without changing the fundamental NAS signaling transmission method, thus maintaining resource efficiency while enabling targeted service provision through the added information layer
2Adaptability or versatility
If service data information is embedded in NAS signaling message, then targeted service provision is enabled, but signaling message complexity increases
Solution Approach 1:
The patent applies the nesting principle by embedding service data information fields within the existing NAS signaling message structure. The service type and priority information are nested as additional elements within the message framework, allowing the network to process service identification without requiring a completely new signaling protocol, thus managing complexity through hierarchical information organization

AI summary
A service data transmission method and a device are disclosed, to resolve a problem in the prior art that a network side cannot provide targeted services for different types of NB-IoT services. The method includes: determining, by an access network device, first information of service data to be sent by a terminal, where the first information includes at least one of a service type and a priority; then receiving, by the access network device, the service data sent by the terminal by using a NAS signaling message; and sending, by the access network device, the service data and the first information to a gateway, so that the gateway charges the service data based on the first information after receiving the service data and the first information.
