A conversation processing method and device

Abstract

The present application discloses a session processing method and device, and a computer storage medium. The method includes: performing a first-type transmission and / or a first-type switching process on a PDU session and / or a data stream in a PDU session, wherein the The above-mentioned first type of transmission includes: the network side and the terminal side perform data replication type transmission on the data packet through multiple paths, and / or perform first-priority transmission on the data packet, and the first-priority transmission refers to The transmitted data flow corresponds to a set of specified QoS parameters; wherein, the first type of handover process includes: before the air interface data radio bearer is handed over from the first base station to the second base station, the second core network element completes the communication with the second base station The establishment of a first path between a base station and the establishment of a second path with the second base station; after the handover of the air interface data radio bearer from the first base station to the second base station is completed, the The second core network element releases the first path between the first base station and the first base station.

Description

[0001] This application is a divisional application of a PCT national phase application with an application date of November 20, 2018, an application number of 201880067822.8, and an invention title of "a conversation processing method and device, and a computer storage medium". technical field [0002] The present application relates to the technical field of wireless communication, 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 is the handover process based on the Xn interface, FIG. 2(a) is the handover preparation process based on the N2 interface, and FIG. 2(b) is the handover execution process based on the N2 interface. During the cross-base station handover process, the main reason ...

[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 is the handover process based on the Xn interface, Figure 2(a) is the handover preparation process based on the N2 interface, and Figure 2(b) is the handover execution process based on the N2 interface

During the cross-base station handover process, the main reason for the temporary interruption of data transmission is that the terminal is always in the single radio (Single Radio) state, and before completing the establishment of a new session (the session on the target base station side), the old session must be disconnected ( The session on the source base station side), the delay and interruption caused by the one-way handover on the air interface side cannot be avoided
