Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvesignaling overheadsVSAvoidaccess efficiency
Core Design Contradiction:
Loss of informationVSProductivity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improveaccess timeVSAvoidaccess procedure complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #10Preliminary action

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.
