Paging Control Mechanism for Idle Mobile Station Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio access technologies waste air interface resources and increase complexity in allocating them due to the lack of a mechanism to stop paging after a mobile station is successfully paged, leading to repeated paging messages from multiple base stations.
Innovation Solution
Implementing a method that includes sending a Paging Announce message to the base station within the paging group containing the mobile station, starting a timer, and stopping paging if no response is received within the predetermined time, with a paging stop notification unit to instruct other base stations to cease paging once successful communication is established.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple base stations continuously send paging messages to an idle mobile station, then the probability of successfully contacting the MS increases, but air interface resources are wasted and allocation complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the base station monitors for paging response messages from the mobile station. When a paging response is detected, the base station sends a paging stop notification to other base stations in the paging group, causing them to cease transmitting paging messages. This feedback loop ensures reliable paging contact while preventing continuous resource waste by dynamically stopping paging transmissions once the MS is successfully contacted.
2Speed
If multiple base stations send paging messages simultaneously, then the MS can be contacted faster, but resource allocation complexity increases
Solution Approach 1:
The patent uses feedback from paging response detection to coordinate resource allocation across multiple base stations. When one base station detects a paging response, it notifies others to stop, creating a simplified resource allocation scheme that maintains fast paging response through parallel monitoring while avoiding the complexity of coordinating simultaneous transmissions.
Solution Approach 2:
The base station that successfully detects the paging response autonomously initiates the paging stop notification to other base stations. This self-service mechanism eliminates the need for a centralized controller to manage resource allocation, reducing system complexity while maintaining efficient paging performance.
3Reliability
If paging continues after successful contact, then no paging failures occur, but air interface resources are unnecessarily consumed
Solution Approach 1:
The patent implements feedback-based paging termination where the base station monitors for paging response messages and, upon detection, sends a paging stop notification to other base stations. This ensures paging continues only as long as necessary to establish contact, preventing unnecessary resource consumption while maintaining high paging completion rates.
Solution Approach 2:
The patent enables the system to discard ongoing paging transmissions once successful contact is established. By stopping paging messages to the contacted MS and notifying other base stations to cease transmissions, the system recovers air interface resources that would otherwise be wasted, making them available for other paging operations.

AI summary
A method for paging an idle MS includes: a PC sends a Paging Announce message to the BS, starts a timer and sets a paging count threshold; the BS pages the MS; if no paging response is received from the MS before expiry of the timer, the PC compares the number of times of paging with the set paging count threshold, and re-sends the Paging Announce message or cancels the paging operation, according to the comparison result. A method for stopping paging to an idle MS includes: a BS in a PG pages an MS, and a network side sends a paging stop message to at least one other BS; and at least one other BS stops the paging process. A paging includes a central processing unit for setting a paging count threshold and judging whether a paging response is received.
