Abstract

The invention discloses a service concurrency method, device and system and a storage medium, and relates to the technical field of mobile communication. The service concurrency method comprises the following steps that a terminal establishes PDU sessions of a plurality of services on a 5G network, wherein the PDU sessions comprise a PDU session of a first service and a PDU session of a second service; the terminal obtains a switching instruction of the PDU session of the first service sent by the network side; the terminal is attached to the 4G network in response to the switching instruction of the PDU session of the first service; a terminal sends a PDN connection establishment request of a first service to a network side through a 4G network, the PDN connection establishment request comprises a PDU session switching instruction and information of a PDU session of the first service in a 5G network, so that the 4G network establishes a PDN connection according to the information of the PDU session of the first service in the 5G network, and the 5G network releases the first PDU session and reserves a PDU session of a second service. Therefore, the concurrence of services on different networks is realized.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a concurrent service method, device, system and storage medium. Background technique [0002] At present, the global 5G commercial use mainly adopts two network architectures: NSA (Non-Standalone, non-independent networking) option3 and SA (Standalone, independent networking) option2. Chinese operators are more actively promoting the commercial use of 5G SA option2. This solution belongs to the 5G independent deployment network. Only the core network 5GC (5G core network) and EPC (Evolve Packet Core, evolved packet core network) have intercommunication interfaces and user data sharing functions to realize business switching between the two networks. Interoperability such as re-election. [0003] When using the SA option2 solution, because the voice solution based on 5G bearer is immature and the wireless coverage of 5G is limited, services such as voice and...
