Base Station Handoff Channel Resource Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular networks, co-channel base stations interfere with switching commands, leading to communication interruptions during base station switching due to shared channel resources, which existing methods fail to adequately address.
Innovation Solution
The method involves acquiring designated channel resource information, identifying and instructing relevant base stations to stop using this resource, and using it for the switching command from the source base station to the mobile terminal, ensuring minimal interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If co-channel base stations use the same channel resource for communication, then channel resource utilization is improved, but interference on the switching command increases causing communication interruptions
Solution Approach 1:
The source base station performs preliminary actions by determining channel resources that will be used by relevant base stations before sending the switching command. This allows the source base station to select a channel resource that minimizes interference from other base stations, ensuring reliable command delivery while maintaining overall channel utilization efficiency.
Solution Approach 2:
The patent applies local quality by selecting a specific channel resource with favorable interference characteristics for the switching command transmission, rather than uniformly using all available channels. The source base station identifies and uses a particular channel resource that has lower interference from relevant base stations, optimizing the local transmission quality for this critical signaling message.
2Ease of operation
If the source base station uses a channel resource for sending the switching command, then the switching command can be transmitted, but interference from co-channel base stations causes the mobile terminal to fail receiving the command in time
Solution Approach 1:
The source base station performs preliminary determination of the channel resource to be used by relevant base stations before transmitting the switching command. This advance planning enables the selection of an optimal channel resource that minimizes interference and ensures timely command delivery, preventing delays in the switching process.
Solution Approach 2:
The patent incorporates feedback mechanisms where the source base station determines and considers the channel resource usage of relevant base stations when selecting the channel for switching command transmission. This feedback information about other base stations' channel usage patterns enables the source base station to make informed decisions that avoid interference and ensure timely command delivery.

AI summary
Embodiments of the present invention provide a method and an apparatus for a mobile terminal to switch a base station, relate to the field of communications technologies, and solve a problem that interference of a co-channel base station on receiving, by a terminal, a switching command is large. The method includes: acquiring designated channel resource information from channel resources used by a source base station; acquiring information of a relevant base station using a designated channel resource except the source base station; sending indication signaling to the relevant base station according to the information of the relevant base station, where the indication signaling carries the designated channel resource information, the indication signaling is used to instruct the relevant base station to stop using the designated channel resource when the mobile terminal switches to a target base station; sending a switching request message to the target base station; and sending the switching command to the mobile terminal through the designated channel resource. The present invention may be applied to switching of the base station performed by the mobile terminal.
