or,

receiving, by the terminal, a second corresponding relationship sent by the first SP device, the second corresponding relationship comprising a corresponding relationship between the priority of the identity credential and the service.

8. The method according to claim 4 , further comprising:

receiving, by the terminal, an instruction of the user, the instruction indicating that the user is to reselect an operator;

receiving, by the terminal, second selection information of the user, the second selection information indicating a second operator selected by the user;

sending, by the terminal, the user request to a second SP device of the second operator; and

after the second SP device indicates that the terminal passes authentication, accessing, by the terminal, a network of the second operator through the second SP device.

9. The method according to claim 4 , further comprising:

receiving, by the terminal, a temporary quitting instruction of the user; and

suspending, by the terminal, user data of the user according to the temporary quitting instruction.

10. The method according to claim 3 , further comprising:

receiving, by the terminal, a service request of the user; and

when a service indicated by the service request is not the service corresponding to the priority of the identity credential, denying, by the terminal, the service request,

wherein the denying, by the terminal, the service request comprises:

presenting, by the terminal, prompting information, the prompting information being configured to indicate the user to input another identity credential corresponding to the service indicated by the service request.

11. The method according to claim 3 , further comprising:

receiving, by the terminal, a user credential input by another user; and

determining, by the terminal, another service corresponding to the identity credential input by the another user to enable the another user to use the another service through the terminal.

12. The method according to claim 3 , further comprising:

receiving, by the terminal, a permanent deactivation instruction of the user; and

deleting, by the terminal, the user data of the user according to the permanent deactivation instruction.

13. A terminal, comprising:

a receiver, configured to receive an identity credential input by a user;

a processor; and

a memory, configured to store codes executed by the processor;

wherein the processor is configured to:

determine an Identity (ID) of the user and a priority of the identity credential according to the identity credential;

acquire subscription information of the user according to the ID of the user; and

determine a service corresponding to the priority of the identity credential according to the subscription information;

wherein the identity credential comprises a primary credential and a secondary credential,

wherein the primary credential comprises at least one of: a DeoxyriboNucleic Acid (DNA), a fingerprint, an iris and a voiceprint,

wherein the secondary credential comprises at least one of: a digital certificate, a digital signature, a user card and a password, and

wherein a priority of the primary credential is higher than a priority of the secondary credential.

14. The terminal according to claim 13 , further comprising a sender, wherein

the receiver is further configured to receive first selection information input by the user, the first selection information indicating a first operator selected by the user;

the receiver is further configured to receive a user request input by the user, the user request comprising the identity credential; and

the sender is configured to send the user request to a first Service Provider (SP) device of the first operator.

15. The terminal according to claim 14 , wherein the receiver is further configured to perform at least one of the following:

acquire the subscription information of the user through the first SP device;

receive a first corresponding relationship sent by the first SP device, the first corresponding relationship comprising a corresponding relationship among the ID of the user, the identity credential and the priority of the identity credential; or

receive a second corresponding relationship sent by the first SP device, the second corresponding relationship comprising a corresponding relationship between the priority of the identity credential and the service.

16. The terminal according to claim 14 , wherein

the receiver is further configured to receive an instruction of the user, the instruction indicating that the user is to reselect an operator;
