Abstract
A method, an apparatus, and a system for selecting a session management network element, where the method includes: A mobility management network element determines a first DNAI corresponding to a first session of a terminal device. The mobility management network element selects, for the first session of the terminal device, a first session management network element that supports all or a part of DNAIs in the first DNAI. Based on this solution, the mobility management network element selects the session management network element for the terminal device. The session management network element supports all or a part of the DNAIs in the first DNAI. Therefore, a user plane network element selected by the session management network element also supports all or a part of the DNAIs in the first DNAI, such that a proper session management network element is selected for the terminal device.
