Abstract

The present invention provides a network access selection method and terminal, where the method includes: acquiring service attribute information corresponding to a service to be performed; determining, according to the service attribute information and a network access selection policy, a preferred access network used by the service to be performed; and performing the service by using the preferred access network. The present invention enables differentiated access networks to be selected for services with different service attributes and makes it easy to implement a network access selection.

Claims

1. A network access selection method, comprising:

acquiring service attribute information corresponding to a service to be performed;

determining, according to the service attribute information and a network access selection policy, a preferred access network used by the service to be performed; and

performing the service by using the preferred access network.

2. The method according to claim 1, wherein:

the network access selection policy comprises;

the service attribute information and the preferred access network corresponding to the service attribute information; and

determining, according to the service attribute information and a network access selection policy, the preferred access network used by the service to be performed comprises;

determining, according to the service attribute information, the preferred access network corresponding to the service attribute information.

3. The method according to claim 1, wherein acquiring the service attribute information corresponding to the service to be performed comprises:

receiving a service link which is used to connect to the service and sent by an application server that is used to provide the service, wherein the service link comprises the service attribute information; and

when it is detected that the service link is triggered, parsing the service link to obtain the service attribute information.

4. The method according to claim 1, wherein the service attribute information comprises at least one of the following:

a quality of service guarantee requirement, a mobility requirement, information about required service traffic, and an access mode preference.

5. The method according to claim 4, wherein the network access selection policy further comprises at least one of the following:

current accounting status information of a user, and network status information.

6. The method according to claim 1, before determining, according to the service attribute information and a network access selection policy, a preferred access network, further comprising:

pre-configuring and storing the network access selection policy.

7. The method according to claim 1, before determining, according to the service attribute information and a network access selection policy, a preferred access network, further comprising:

interacting with an access network discovery and selection function entity or a capability enabling platform to acquire the network access selection policy.

8. The method according to claim 1, after determining the preferred access network used by the service to be performed, further comprising:

displaying selection prompt information when it is determined that the preferred access network is unavailable currently, wherein the selection prompt information is used to prompt a user of the service to choose whether to still use the preferred access network.

9. The method according to claim 8, after displaying the selection prompt information, further comprising:

when the user of the service chooses to still use the preferred access network, waiting until the preferred access network is available and then executing performing the service by using the preferred access network.

10. The method according to claim 1, before performing the service by using the preferred access network, further comprising:

interacting with an access network discovery and selection function entity or a capability enabling platform to acquire network information of the preferred access network; and

accessing the preferred access network according to the network information.

11. A terminal, comprising:

an information acquiring unit, configured to acquire service attribute information corresponding to a service to be performed;

a network selecting unit, configured to determine, according to the service attribute information and a network access selection policy, a preferred access network used by the service to be performed; and

a service executing unit, configured to perform the service by using the preferred access network.

12. The terminal according to claim 11, wherein:

the network access selection policy comprises;

service attribute information and a preferred access network corresponding to the service attribute information; and

the network selecting unit is configured to;

determine, according to the service attribute information, the preferred access network corresponding to the service attribute information.

13. The terminal according to claim 11, wherein the information acquiring unit comprises:

a receiving subunit, configured to receive a service link which is used to link the service and sent by an application server that is used to provide the service, wherein the service link comprises the service attribute information; and

a parsing subunit, configured to;

when it is detected that the service link is triggered, parse the service link to obtain the service attribute information.

14. The terminal according to claim 11, wherein the service attribute information acquired by the information acquiring unit comprises at least one of the following:

a quality of service guarantee requirement, a mobility requirement, information about required service traffic, and an access mode preference.

15. The terminal according to claim 14, wherein the network access selection policy further comprises at least one of the following:

current accounting status information of a user, and network status information.

16. The terminal according to claim 11, further comprising:

a policy configuring unit, configured to pre-configure and store the network access selection policy.

17. The terminal according to claim 11, further comprising:

a policy acquiring unit, configured to interact with an access network discovery and selection function entity or a capability enabling platform to acquire the network access selection policy.

18. The terminal according to claim 11, further comprising:

a selection prompting unit, configured to display selection prompt information if it is determined that the preferred access network is unavailable currently, wherein the selection prompt information is used to prompt a user of the service to choose whether to still use the preferred access network.

19. The terminal according to claim 18, wherein:

the network selecting unit is further configured to;

if the user of the service chooses to still use the preferred access network, wait until the preferred access network is available and then instruct the service executing unit to perform the service by using the preferred access network.

20. The terminal according to claim 11, further comprising:

a network access unit, configured to interact with an access network discovery and selection function entity or a capability enabling platform to acquire network information of the preferred access network; and

access the preferred access network according to the network information.
