Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network device access methods involve high signaling overheads due to multiple exchanges required for obtaining parameter configurations, such as cell search, PLMN selection, and random access, leading to inefficient communication.
Innovation Solution
A network device access method that reduces signaling overheads by providing parameter configuration information indicating the time-frequency resource and cell needed for data transmission, allowing terminals to access the network device with a single exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional cell search, PLMN selection, and random access procedures are used for network device access, then the terminal can obtain necessary parameter configurations, but signaling overheads become high due to multiple exchanges
Solution Approach 1:
The patent combines multiple parameter configurations (time-frequency resource, cell information, bandwidth part, random access preamble) that were previously obtained through separate signaling exchanges into a single unified parameter configuration message. This merging of information delivery into one exchange directly reduces signaling overhead while maintaining all necessary access parameters.
Solution Approach 2:
The network device performs preliminary preparation by determining and providing all necessary parameter configurations in advance through the single parameter configuration message. This preliminary action includes pre-determining time-frequency resources, cell information, bandwidth part configurations, and random access preamble information, allowing the terminal to access without multiple subsequent exchanges.
2Loss of time
If multiple signaling exchanges are performed to obtain parameter configurations, then comprehensive parameter information can be obtained, but the access time and complexity increase
Solution Approach 1:
The patent merges multiple access procedures (cell search, PLMN selection, random access) into a single streamlined procedure where all necessary parameters are provided in one configuration message. This reduces both the time required and the procedural complexity by eliminating multiple separate signaling exchanges.
Solution Approach 2:
The network device performs all necessary parameter determination in advance and provides them together in a single message. This preliminary action eliminates the need for the terminal to engage in multiple sequential procedures, thereby reducing both access time and procedural complexity.

AI summary
This application provides a network device access method and apparatus. A terminal receives parameter configuration information, where the parameter configuration information is used to indicate a time-frequency resource required by the terminal to transmit data and a cell that can be used by the terminal to transmit the data; and further accesses a network device based on the parameter configuration information. To be specific, the terminal may obtain, based on one piece of parameter configuration information, the time-frequency resource required to transmit the data and the cell that can be used to transmit the data, and does not need to obtain, by configuring different pieces of configuration information for a plurality of times, the time-frequency resource required to transmit the data and the cell that can be used to transmit the data. Different pieces of configuration information are carried by using different pieces of signaling in a conventional solution, while the parameter configuration information in embodiments of this application may be carried in one piece of signaling, so that signaling overheads are reduced.
