Referring to fig. 1 and fig. 2, fig. 1 is a schematic flowchart of a terminal persistent communication method based on 5G base station handover according to an embodiment of the present invention; fig. 2 is a schematic view of an application scenario of a terminal persistent communication method based on 5G base station handover according to an embodiment of the present invention; the terminal continuous communication method based on the 5G base station switching is applied to a 5G communication service network 10, the 5G communication service network 10 is used for providing 5G communication service for a client, the 5G communication service network 10 comprises a core network server 101 and a plurality of base stations 102, the terminal continuous communication method based on the 5G base station switching is executed through application software installed in the core network server 101 and each base station 102, the client 20 can establish network connection with the core network server 101 through any base station 102 to realize wireless transmission of data information, and the base station 102 establishes network connection with other adjacent base stations 102 to realize transmission of the data information; the core network server 101 is a core network end constructed by a telecommunications carrier for providing a 5G communication service to the client 20, the base station 102 is a communication base station for providing wireless communication access, such as a fixed base station or a vehicle-mounted mobile base station installed at a top end of a building, and the client 20 is a terminal device for a user to use and perform wireless data transmission with the core network server 101, for example, a 5G terminal device such as a notebook computer, a tablet computer, a mobile phone, or a wearable terminal device such as a smart watch, smart glasses. Fig. 2 only illustrates that one client 20 accesses the 5G communication service network 10 and performs information transmission, and in practical applications, the 5G communication service network 10 may also establish communication connections with multiple clients 20 at the same time to implement data information transmission.

In the actual application process, if a plurality of clients are simultaneously accessed or switched to the second base station, the plurality of switching request messages/access request messages need to be sequenced according to the service priority of each client, the request message with the highest priority is acquired, the reserved resource of the base station is preferentially allocated, and the request message with the lower priority is allocated with the reserved resource of the base station later. Specifically, the corresponding base station reserved resource may be allocated to the client corresponding to the handover request message according to the number of RB resource blocks in the initial resource reservation information, the communication frequency of the channel resource, and the like, and a corresponding life cycle may be allocated to the allocated base station reserved resource according to the life cycle information in the service resource information.

The core network server can receive the switching notification message from the second base station, and sends the notification message of successful reservation to the first base station after the core network reserved resources are distributed according to the switching notification message. The reserved resources of the core network are reserved resources allocated by the server side of the core network according to the requirement of the client for service message transceiving.
In an embodiment, as shown in fig. 5, step S140 includes sub-steps S141, S142 and S143.
