Mobile Station Handover Priority Indicator Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile station handover techniques in wireless networks lack the ability to differentiate between various priority levels and reasons for handover requests, leading to inefficient and sometimes critical network disruptions due to unnecessary rejections or negotiations.
Innovation Solution
Incorporating a priority indicator in handover requests and responses to enable mobile stations to process handover instructions based on specific criteria, distinguishing between mandatory and recommended handovers, and allowing for more efficient handling of handover requests and responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional handover techniques are used without priority differentiation, then the handover process is simple, but network disruptions occur due to unnecessary rejections or negotiations
Solution Approach 1:
The patent introduces a priority indicator parameter in handover request messages to differentiate between mandatory and recommended handovers. This parameter change enables the mobile station to prioritize handover requests, reducing network disruptions while maintaining a relatively simple handover process structure
Solution Approach 2:
The patent segments handover requests into different priority levels (mandatory and recommended). By categorizing handover requests based on priority, the system can handle critical handovers differently from optional ones, improving reliability without significantly complicating the overall handover mechanism
2Productivity
If priority indicators are incorporated in handover requests, then handover efficiency improves, but message complexity increases
Solution Approach 1:
The patent adds a priority indicator parameter to existing handover request messages. This minimal parameter addition enables efficient prioritization of handover requests without fundamentally changing the message structure or protocol, thus improving productivity with minimal increase in message complexity
3Reliability
If mobile stations reject handover requests without priority consideration, then device autonomy is maintained, but network performance degrades
Solution Approach 1:
The patent modifies the mobile station's decision-making process by introducing a priority indicator parameter. The mobile station uses this parameter to distinguish between mandatory handovers (which should be accepted) and recommended handovers (which can be evaluated based on local conditions). This improves network performance while maintaining mobile station autonomy through simplified decision rules

AI summary
A method and system for processing a handover request in a wireless network. The method includes receiving a first message from a first base station by a mobile station. The first message includes a handover request, the handover request includes a priority indicator, and the priority indicator indicates a priority level selected from a plurality of priority levels. Additionally, the system includes determining the priority level based on at least information associated with the first message by the mobile station, processing information associated with the priority level by the mobile station, and determining at least one criterion based on at least information associated with the priority level by the mobile station. Moreover, the system includes processing information associated with the handover request and the at least one criterion by the mobile station.
