Embodiment Construction

[0046] Under the conditions of explosive data volume and diverse needs of users, a user-centric 5G mobile communication technology for an all-round information ecosystem is proposed. interconnection, and provide fiber-like access speed. At present, the feasible access methods for base stations to access the core network based on 5G mobile communication technology include but are not limited to figure 1 and figure 2 shown.

[0047] in figure 1 It shows that two gNBs (NRNode, 5G base station) (referred to as the first gNB and the second gNB for the convenience of explanation) access the core network based on 5G mobile communication technology (abbreviated as NextGen Core), and the first gNB corresponds to the coverage of the cell is within the coverage of the cell corresponding to the second gNB, figure 2 It shows that a gNB and an eNB (E-UTRANNodeB, LTE base station) are connected to the NextGen Core, and the coverage of the cell corresponding to the gNB partially overlap...

Abstract

The invention provides a communication switching method and device. The communication switching method comprises the following steps: determining a target base station from all first base stations according to the information after obtaining signal quality parameters of a source base station, signal quality parameters of each first base station and load of each first base station for source base stations and first base stations which are accessed into a core net based on a 5G mobile communication technology; and sending switching request to the target base station, sending switching order information to the terminal after receiving switching request conformation information sent by the target base station for indicating the terminal to switch to the target base station from the source base station, thereby realizing communication switching under the 5G mobile communication technology. In a communication switching process, switching request carries service quality flow related information, so that the source base station and the target base station can adopt same service quality flow related information to perform mapping of service quality flow, and therefore, loseless switching of service quality flow can be realized in a process of switching the terminal to the target base station, and continuity and service quality of communication are improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and more specifically, relates to a communication switching method and device. Background technique [0002] With the growth of user demand and the development of communication technology, more and more mobile communication technologies have emerged in the field of wireless communication, such as 2G (2-Generation, second generation), 3G, 4G and 5G, which are four mobile communication technologies that coexist and develop , so the cooperation and integration between base stations based on the same mobile communication technology and different mobile communication technologies is the development trend of wireless communication, and the cooperation and integration between base stations can be realized through handover technology. [0003] The handover process refers to: when the signal quality of the source base station (the base station corresponding to the cell currently accessed by...
