Network Access Method and Terminal

A terminal, comprising:

• a memory;
• a radio frequency (RF) circuit coupled to the memory using a bus and configured to:
• obtain a priority of a first network service;
• and
• obtain a network service class of a first network currently accessed by the terminal;
• and
• a processor coupled to the memory and the RF circuit using the bus and configured to:
• determine, according to a relationship between a network service priority and a network service class, a network service class required for performing the first network service, the relationship being stored in the memory, and the network service class indicating network quality;
• access a second network when the network service class of the first network is lower than the network service class required for performing the first network service;
• and
• perform the first network service using the second network, a network service class of the second network being higher than the network service class of the first network.

A non-transitory computer-readable storage medium comprising instructions which, when executed by a terminal, cause the terminal to carry out the following steps of:

• obtaining a priority of a first network service;
• determining, according to a relationship between a network service priority and a network service class, a network service class required for performing the first network service, the relationship being stored in the terminal, and the network service class indicating network quality;
• obtaining a network service class of a first network currently accessed by the terminal;
• accessing a second network when the network service class of the first network is lower than the network service class required for performing the first network service;
• and
• performing the first network service using the second network, a network service class of the second network being higher than the network service class of the first network.
