Problems solved by technology

[0003] The existing technology provides a method for the user equipment to move between the 2 / 3G network and the 4G network to achieve service continuity, but if the user equipment accesses the 2 / 3G network, moves to the 4G network, and then moves from the 4G network to the 5G network At this time, the UE needs to re-connect to the 5G network, resulting in the interruption of the service used by the user under the 4G network, and the service continuity cannot be maintained.

Embodiment Construction

[0051] Embodiments of the present application are described below with reference to the drawings in the embodiments of the present application.

[0052] see figure 1 , figure 1 It is a schematic diagram of the communication system provided by the embodiment of this application.

[0053] The communication system provided in the embodiment of the present application includes a 2 / 3G network, a 4G network and a 5G network. A user equipment (user equipment, UE) can access a 2 / 3G network through a 2 / 3G access network device, access a 4G network through a 4G access network device, or access a 5G network through a 5G access network device. Access network devices may include base stations and the like. Wherein, 2G network includes global system for mobile communication (GSM) network, code division multiple access (code division multiple access) network, 3G network includes wideband code division multiple access (wideband code division multiple access, WCDMA), CDMA2000 network and t...

Abstract

The embodiment of the present application discloses a method, related equipment and system for realizing business continuity. In the method provided in this embodiment, the mobile management device can select a 5G gateway for a 5G user equipment switched to a 4G network, and establish a session with the 5G gateway, and the 5G gateway can send 5G-related parameters to the user equipment in advance, Therefore, after the user equipment moves from the 4G network to the 5G network, service continuity is maintained, that is, services on the 4G network continue to be maintained on the 5G network.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method, a related device and a system for realizing service continuity. Background technique [0002] In the existing mobile communication network, the coverage of 2G or 3G network (referred to as 2 / 3G network) is wider than that of 4G network, and the coverage of 4G network is wider than that of the initial 5G network. In order to ensure that 5G users can continue their services when they leave the 5G network coverage area (for example, the user's data service is not interrupted), network operators usually superimpose the 5G network within the coverage area of ​​the 4G network. Therefore, when the user equipment is moving, it usually moves from the 5G network area to the 4G network area, and then moves to the 2 / 3G network area. Or connect to the 2 / 3G network area, then move to the 4G network area, and then move to the 5G network area. [0003] The existin...
