Network Handover via Virtual Base Station Capability Negotiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing network handover methods from a non-WiMAX network to a WiMAX network are inefficient, as they require multiple attempts to determine the appropriate handover manner, leading to delayed and inefficient handover processes.
Innovation Solution
A method that involves obtaining information on the handover manner supported by the virtual base station and sending a corresponding message to initiate the handover, allowing the terminal to be directly handed over from the virtual base station to the target base station in the supported manner, either through initiate handover or idle mode handover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple handover attempts are made to determine the appropriate handover manner, then the handover can be completed, but the handover time is delayed and the efficiency is reduced
Solution Approach 1:
The terminal performs capability negotiation with the virtual base station before handover to obtain information about supported handover manners. This preliminary action allows the terminal to know in advance which handover manner (initiate handover or idle mode handover) the virtual base station supports, eliminating the need for multiple trial attempts and reducing handover time while ensuring reliable handover completion.
2Reliability
If the terminal attempts handover in one manner first and switches to another manner if rejected, then handover can be completed, but the handover process becomes complex and time-consuming
Solution Approach 1:
The terminal performs capability negotiation with the virtual base station before handover to obtain information about supported handover manners. This preliminary action allows the terminal to directly select the appropriate handover manner without trial-and-error attempts, reducing process complexity while ensuring reliable handover completion.
Solution Approach 2:
The virtual base station provides feedback to the terminal about which handover manners it supports through capability negotiation. This feedback mechanism allows the terminal to make an informed decision about which handover manner to use, eliminating the need for complex trial-and-error logic and simplifying the overall handover process.
3Productivity
If capability negotiation is performed before handover, then the appropriate handover manner can be determined in advance, but additional signaling is required
Solution Approach 1:
The capability negotiation for handover manner information is merged with the existing ranging and base station capability negotiation procedures that already occur before handover. By combining these signaling exchanges, the patent obtains handover manner information without adding significant additional signaling overhead, while greatly improving handover efficiency by eliminating multiple trial attempts.

AI summary
A method, a system and a device for network handover are provided, which are applied to the field of communications technologies. The method includes the following steps that: a terminal first obtains information of a handover manner of handover from a virtual base station to a target base station, and then sends a corresponding message to the virtual base station according to the information of the handover manner, so as to perform network handover, so that in a procedure that the terminal is handed over from a non-WiMAX network to a WiMAX network, the terminal may be directly handed over according to the handover manner supported by the virtual base station. Compared with the conventional art in which handover manners require handover attempts, the adoption of the method for network handover reduces handover time and increases network handover efficiency.
