Base Station Control of User Equipment Transmission Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication network systems, base stations face challenges in making acquisition decisions regarding the allocation of common channels for message transmission from user equipment, as they cannot determine the nature or priority of the message being sent, leading to potential congestion and inefficient scheduling.
Innovation Solution
Incorporating additional information about the type and priority of the message into the signal transmitted from the user equipment to the base station, which must be acknowledged before the message is sent, allowing the base station to make informed acquisition decisions and prioritize higher-priority messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If common channels are used for message transmission when dedicated channels are not allocated, then channel resource utilization is improved, but the base station cannot judge the message content for making acquisition decisions
Solution Approach 1:
The transmission signal is segmented into two parts: a first part containing only message type information (without the actual message content) and a second part containing the actual message. The base station first processes the first part to make acquisition decisions, then selectively processes the second part based on those decisions.
Solution Approach 2:
The message type information is transmitted and processed in advance before the actual message transmission. This preliminary action allows the base station to make informed acquisition decisions about whether to allocate resources for the subsequent message transmission.
2Ease of operation
If the base station allocates common channels without message type information, then channel allocation simplicity is maintained, but message prioritization and congestion management deteriorate
Solution Approach 1:
Message type information is provided in advance in the first part of the signal, enabling the base station to perform preliminary judgment and prioritization before allocating channel resources for the actual message transmission.
Solution Approach 2:
Message type information acts as an intermediary element between the user equipment and the base station, carrying essential classification data that enables informed resource allocation decisions without requiring the base station to process full message content.
3Measurement precision
If additional information about message type is transmitted before the message, then acquisition decision accuracy is improved, but signal transmission complexity increases
Solution Approach 1:
The signal is divided into distinct segments: a first part containing message type information and a second part containing the actual message. This segmentation allows the base station to process only the essential information first for acquisition decisions.
Solution Approach 2:
The essential message type information is extracted and transmitted separately in the first part, allowing the base station to make acquisition decisions based on this extracted information without needing to process the entire message content.

AI summary
A signal is transmitted in a communication network system, in particular a mobile communication network system, from a user equipment, in particular a mobile user equipment, to a base station, which signal includes an information about the kind of a message intended to be transmitted from said user equipment to said base station, wherein said information must be acknowledged by said base station as a condition for transmitting said message from said user equipment to said base station.
