Abstract

The present disclosure relates to a handover method, a network device and a system in a multi-connectivity network. The method includes: determining a type of a user of a terminal during a handover procedure of the terminal to a multi-connectivity network of the construction operator; determining a user plane split policy corresponding to the terminal according to the type of the user of the terminal; and switching a user plane channel of the terminal to a user plane channel of a first standard network of the construction operator, in a case that the user plane split policy is split-disabled, and switching the user plane channel of the terminal to the user plane channel of the first standard network and a user plane channel of a second standard network of the construction operator, in a case that the user plane split policy is split-enabled.

Claims20

Dependent claims

A handover method in a multi-connectivity network, performed by a network device of a construction operator, comprising:

determining a type of a user of a terminal during a handover procedure of the terminal to a multi-connectivity network of the construction operator, wherein the type comprises:
a first type indicating that the user is a user of a sharing operator or a second type indicating that the user is a user of the construction operator;
determining a user plane split policy corresponding to the terminal according to the type of the user of the terminal;
switching a user plane channel of the terminal to a user plane channel of a first standard network of the construction operator, in a case that the user plane split policy corresponding to the terminal is split-disabled, and switching the user plane channel of the terminal to the user plane channel of the first standard network and a user plane channel of a second standard network of the construction operator, in a case that the user plane split policy corresponding to the terminal is split-enabled, wherein the first standard network and the second standard network are networks of different network standards;
and
switching a control plane of the terminal to a control plane channel of the second standard network of the construction operator.
