Session line switching method and system

Abstract

The invention discloses a conversation line switching method and system. The method includes: when the terminal conducts a session with the session peer through the first user plane functional entity based on the first network, and the current signal quality of the terminal is lower than a preset quality threshold, the terminal performs non-3GPP interoperability on the non-3GPP network The functional entity accesses the first network; the terminal establishes a data connection relationship with the second user plane functional entity corresponding to the first network in response to the access success message returned by the non-3GPP interoperability functional entity; the terminal establishes a data connection relationship with the first network corresponding to the first network. The session management functional entity sends a session line switching request; the first session management functional entity interacts with the second session management functional entity corresponding to the first network according to the session line switching request, and completes the switching of the session context; the first user plane functional entity communicates with the The second user plane functional entity interacts to complete session line handover.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for switching a session line. Background technique [0002] At present, when a terminal user makes a call through a terminal (such as a mobile phone), it often encounters the situation that the voice is intermittent or the call is disconnected due to poor call signal. At this time, the terminal user usually needs to walk around to try to find the network signal Locations with better coverage to keep calls going, resulting in a poor user experience. [0003] Therefore, how to ensure the smoothness of the user's call when the call signal is poor, so as to improve the user's experience has become a technical problem to be solved urgently. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems in the prior art, and provides a method and system for switching a session line. [0005] To achieve the abo...
