Patent ID: 11627508

Abstract:
Provided are session processing method, device, and computer storage medium. The method includes performing at least one of a first type transmission, a first type handover process on the PDU session, or the data stream in the PDU session. The first type of transmission includes at least one of the network side and the terminal side perform data copy type transmission on the data packet through multiple paths, or perform the first priority transmission on the data packet. The first priority transmission refers to that the transmitted data stream corresponds to a set of specific QoS parameters. The first type of handover process includes before the air interface data radio bearer is handover from the first base station to the second base station. The second core network element completes the establishment of a first path with the first base station and the establishment of a second path with the second base station. The first type of handover process also includes after the air interface data radio bearer is handover from the first base station to the second base station, the second core network element releases the first path with the first base station.
