Abstract

The invention provides a session management method and device. The method comprises the following steps: a session management network element distributes a first IP address and a first user plane network element to the terminal, and the first user plane network element distributed for the terminal supports the first IP address, so that the user plane network element which does not support the first IP address can be prevented from being distributed for the terminal, and the resource waste caused by redistributing the IP address for multiple times or reselecting the user plane network element can be prevented.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a session management method and device. Background technique [0002] In the core network, a user plane function (UPF) network element can be managed by one or more session management function (SMF) network elements, and one SMF network element can also manage one or more UPF network element. For a UPF network element, the IP address supported by the SMF network element that manages the UPF network element can be assigned to the UPF network element. It can also be understood that the IP address supported by the UPF network element is the IP address that manages the UPF network element. All network protocol (internet protocol, IP) addresses supported by the SMF network element. [0003] Currently, in some specific scenarios, such as enterprise networks, dedicated UPF network elements are deployed in the enterprise network. Since the enterprise network...
