Network Resource Allocation for Multi-Access Technology Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in implementing communication across different access technologies in a network, where existing methods struggle to standardize deployment locations and resources, leading to inefficiencies and resource wastage due to the varying requirements of services and access technologies deployed by different operators on the same frequency band.
Innovation Solution
A network device broadcasts information about access technologies and corresponding resources, allowing terminal devices to select suitable access technologies and resources based on service requirements, enabling communication across multiple access technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different access technologies are deployed by different operators on the same frequency band, then service diversity and flexibility are improved, but resource standardization and deployment efficiency deteriorate
Solution Approach 1:
The patent segments the frequency band into multiple resource blocks, each assigned to different access technologies. This allows different operators to deploy their preferred access technologies (NB-GSM, NB-M2M, NB-OFDM, NB-CIoT) on the same frequency band without conflict, while maintaining resource standardization through the resource block framework. The segmentation enables service diversity while preventing resource management chaos.
2Measurement precision
If access technology specific information is broadcast for each technology, then terminal device access accuracy is improved, but network device complexity and resource wastage increase
Solution Approach 1:
The patent creates a universal resource block structure that can accommodate multiple access technologies. Instead of creating separate broadcast mechanisms for each access technology, a single resource block assignment system serves all technologies (NB-GSM, NB-M2M, NB-OFDM, NB-CIoT). This universal approach maintains access accuracy for each technology while reducing network device complexity and eliminating resource wastage from duplicate broadcast structures.
3Adaptability or versatility
If multiple access technologies are supported simultaneously, then network service coverage is improved, but resource allocation efficiency and deployment standardization worsen
Solution Approach 1:
The patent changes the parameter organization from technology-specific resource allocation to resource block-based allocation. By defining resources in standardized blocks that can be assigned to different access technologies, the system maintains service coverage for multiple technologies while improving resource allocation efficiency. The resource block parameters are changed to be technology-agnostic, allowing efficient allocation across NB-GSM, NB-M2M, NB-OFDM, and NB-CIoT services.

AI summary
The present invention relates to the field of communications technologies and discloses a communication method and an apparatus. The method includes: obtaining, by a terminal device, information about an access technology corresponding to a first service; receiving, by the terminal device, information about an access technology and resource information corresponding to the access technology that are broadcast by a network device; determining, by the terminal device based on the obtained information about the access technology corresponding to the first service, and the information about the access technology and the resource information corresponding to the access technology that are broadcast by the network device, a first resource corresponding to the first service; and sending, by the terminal device, an access request to the network device by using the first resource. The terminal device determines, based on information about an access technology corresponding to a required service, a resource corresponding to the service, and accesses a network by using the resource. In this way, communication when a plurality of access technologies are used is implemented.
