Abstract

The application provides a kind of offshore 5G and self-organizing network fusion communication method and system, belongs to mobile communication technical field, aims at solving the problems of "ping-pong effect", large switching delay, non-optimal relay selection and discontinuous QoS guarantee of traditional dual-mode communication in complex offshore environment.The application calculates connection quality score by comprehensively reporting communication parameters of terminal from network side decision server, and predicts its future trend;According to the key network parameters such as 5G cell load and ad hoc network path hop number, dynamically adjust the switching threshold T1 and T2.When the predicted CQS will cross the threshold, trigger the pre-registration and session pre-establishment operation in advance to realize seamless switching.In the ad hoc network side, the optimal relay node is selected by the algorithm of stability, load and energy, and dynamic updating is supported.By establishing the mapping rule of 5QI and DSCP and being controlled by 5G core network, the end-to-end QoS continuity is ensured.The application improves the intelligent level, link stability and service experience of offshore communication.
