Session processing method and device and computer storage medium

Abstract

The invention discloses a session processing method and device and a computer storage medium. The method comprises the following steps of: performing a first type of transmission and / or a first type of switching process on a PDU session and / or a data stream in the PDU session, wherein the first type of transmission comprises the following steps that: a network side and a terminal side perform datareplication type transmission on a data packet through a plurality of paths, and / or perform transmission of a first priority on the data packet, wherein the transmission of the first priority means that the transmitted data stream corresponds to a group of specified QoS parameters; wherein the first type of switching process comprises the following steps: before an air interface data radio beareris switched from a first base station to a second base station, a second core network element completes establishment of a first path between the second core network element and the first base station and establishment of a second path between the second core network element and the second base station; and after the air interface data radio bearer is switched from the first base station to the second base station, the second core network element releases a first path between the second core network element and the first base station.

Description

[0001] This application is a divisional application of a PCT national phase application with the filing date of November 20, 2018, the application number being 201880067822.8, and the invention title being "a session processing method and device, computer storage medium". Technical field

[0002] This application relates to the field of wireless communication technology, and in particular to a session processing method and device, and a computer storage medium. Background technique

[0003] At present, cross-base station handover in the same core network will cause a short interruption of data transmission. The current handover process is as follows figure 1 , Figure 2(a), Figure 2(b), where, figure 1 It is the switching process based on the Xn interface. Figure 2(a) is the switching preparation process based on the N2 interface, and Figure 2(b) is the switching execution process based on the N2 interface. In the process of cross-base station handover, the main reason for the short...
