Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If downlink data is transmitted through a CSG after the mobile device moves to a new area, then the service transmission path is extended, but the service transmission latency increases and communication reliability decreases
Solution Approach 1:
The system performs preliminary actions by predicting the mobile device's future location range before the device actually moves there, pre-determines target CSGs that will be in coverage, and pre-establishes tunnels between the MASG and these target CSGs. This allows downlink data to be transmitted directly through the pre-established tunnel when the device enters the coverage area, avoiding the need to route data through the previous serving CSG and thereby reducing service transmission latency while improving communication reliability
2Adaptability or versatility
If the mobile device moves out of the coverage area of the current serving CSG, then the mobile device can access new areas, but the service transmission is interrupted
Solution Approach 1:
The system predicts the mobile device's future location and pre-determines target CSGs before the device leaves the current coverage area. Tunnels are pre-established with these target CSGs, ensuring that when the device moves into the new coverage area, data transmission can continue seamlessly through the pre-configured tunnel without interruption, thus maintaining service transmission reliability while enabling coverage area adaptability
Solution Approach 2:
The system continuously monitors the mobile device's location, movement speed, and direction, and uses this feedback information to dynamically update the predicted location range and adjust the target CSG selection. This feedback mechanism ensures that the pre-established tunnels always point to the correct target CSGs, maintaining service transmission continuity as the device moves through different coverage areas

AI summary
This application provides a cell site gateway CSG determining method and apparatus. The method includes: A first device obtains, before a first moment, a location range in which a mobile device is located at the first moment; and the first device obtains an identifier of at least one target CSG based on the location range before the first moment, where the at least one target CSG can provide downlink data transmission for the mobile device at the first moment. The target CSG that can provide the downlink data transmission for the mobile device at the first moment is further determined through estimation of the location range in which the mobile device is located at a subsequent first moment. Therefore, a tunnel can be established between an MASG and the target CSG before the first moment, and the MASG can send, through the tunnel established in advance, downlink data of the mobile device to the target CSG before the first moment. When moving to the location range at the first moment, the mobile device can reliably receive the downlink data. In this way, communication reliability and user experience can be improved.
