Network selection method and apparatus, terminal, and network-side device

A terminal, comprising a processor, a memory, and a program or instructions stored in the memory and capable of running on the processor, wherein the program or instructions, when executed by the processor, causes the terminal to perform:

• obtaining network selection policy information, wherein the network selection policy information comprises a network identifier of at least one network and a network selection condition corresponding to the at least one network, and the at least one network comprises at least one non-public network;
• and
• determining, based on the network selection condition corresponding to the at least one network, a target network to be accessed, wherein the network selection condition comprises at least one of the following:
• time information, or location information,
• wherein the determining, based on the network selection condition corresponding to the at least one network, a target network to be accessed comprises:
• determining, based on a first priority order, that a first network meeting the network selection condition is the target network, wherein
• the first priority order represents an order of priorities of networks, and the priorities of the networks comprise priorities of at least two of the following:
• a network with which the terminal is previously registered, a network to which the terminal has subscribed, a network in a network list controlled by a user, a network in a network list controlled by a credential holder, a network in a group comprised in a group identifier GIN list controlled by the credential holder, and a second network, wherein the second network is a network allowed to be accessed other than an accessible network configured for the terminal.
