Abstract: Embodiments relate to a network selection method and an apparatus. The method comprises: after receiving an access request message from a UE, a first core network device may send, to the UE, information about a dedicated second core network device corresponding to the UE, thereby ensuring that the UE can be attached to the dedicated second core network device according to the information about the dedicated second core network device, increasing selection accuracy when a core network device is selected for the user terminal, and avoiding occurrence of an access failure of the user terminal to the greatest extent.
