Unified Paging Channel for Wireless Mobile Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of mobile terminal operations and resource waste arise from the need to receive multiple separate channels for paging messages, system information, and notifications in wireless communication systems, particularly in 3GPP systems, which complicates the detection and processing of dynamic system information.
Innovation Solution
The method involves dynamically separating system information into primary and non-primary components, with primary information transmitted statically and non-primary information transmitted dynamically, using a flexible scheduling mechanism to indicate the location of resource blocks within sub-frames, allowing for efficient resource allocation and future expansions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate channels are used for transmitting paging messages, system information, and notifications, then the transmission of different types of information is ensured, but the complexity of mobile terminal operations increases and resources are wasted
Solution Approach 1:
The patent combines multiple separate channels (paging channel, system information channel, notification channel) into a single unified physical downlink shared channel. This merging reduces the number of channels the terminal must monitor and process, thereby reducing operational complexity while maintaining the ability to transmit different types of information through logical channel multiplexing
2Reliability
If multiple separate channels are used for transmitting paging messages, system information, and notifications, then the transmission of different types of information is ensured, but resource waste occurs
Solution Approach 1:
By merging multiple channels into one shared channel, the patent eliminates redundant resource allocation overhead associated with maintaining separate physical channels. The unified channel structure allows more efficient resource utilization while logical channel division ensures reliable transmission of different information types
3Adaptability or versatility
If system information is transmitted dynamically, then the adaptability to channel changes is improved, but the complexity of detecting and processing system information increases
Solution Approach 1:
The patent segments system information into different logical channels (system information channel, paging channel, notification channel) that are multiplexed on a single physical channel. This segmentation allows dynamic transmission adaptability while simplifying detection, as the terminal can identify and process only the relevant logical channel based on pre-configured parameters and indicators

AI summary
In a wireless mobile communications system, a method for processing paging information allows the operations of a mobile terminal to be simplified and permits efficient use of resources for the mobile terminal. The network instructs in advance, the transmission of control information, such as a particular paging message, a notification message, system information and the like, via a single indicator channel. The mobile terminal receives this single indicator channel and uses the indicator information that was transmitted via the indicator channel in order to receive the control information.
