Embodiment Construction

[0030] Those skilled in the art understand that, as mentioned in the background technology, the existing service migration solution in the state of dual registration (such as 5G and 4G dual registration) is to establish a network connection and perform service migration in the target standard after the terminal initiates service migration upper-layer signaling interaction. For delay-sensitive services (such as IMS-based voice services, Voice over LTE, referred to as VoLTE, also known as VoLTE phones), the delay from establishing a network connection at the lower layer to completing signaling interaction at the upper layer is relatively large, which affects users use experience.

[0031] In order to solve the above-mentioned technical problems, an embodiment of the present invention provides a service migration method in a dual registration state, including: determining a pre-migration threshold value of a migration index in response to the establishment of a first service in t...

Abstract

The invention discloses a service migration method and device in a double-registration state, a storage medium and a terminal. The method comprises the steps of determining a pre-migration threshold value of a migration index in response to the fact that a first service is established in a first system, with the migration index being associated with the first service established in the first system, and the pre-migration threshold value being higher than the migration threshold value of the migration index; before service migration is triggered, indicating a second system to establish or maintain network connection based on the migration index; and in response to the fact that the service migration is triggered, executing a service migration operation based on the network connection so asto switch the first service from a first system to a second system. Through the scheme of the invention, the service migration time delay of the double radio frequency terminal in the double registration state can be effectively reduced, and the user experience is optimized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a service migration method and device, a storage medium, and a terminal in a dual registration state. Background technique [0002] At present, there are already basic methods for business migration in the state of dual registration (such as 5G and 4G dual registration). Specifically, when service migration is required, user equipment (User Equipment, UE for short) initiates the migration of the corresponding bearer under the target standard. [0003] For example, when services need to be migrated to 4G due to poor 5G signal coverage, the UE initiates handover (Handover) on the 4G network to activate the Public Data Network (PDN) so that the corresponding 5G protocol The data unit (Protocol Data Unit, PDU for short) session (Session) is migrated to 4G, thereby completing the service migration. [0004] However, the existing service migration mode in the dual regi...
