Abstract

A multi-card user equipment and a method for processing its service are provided. The method includes, when receiving service request corresponding to a first subscriber identity card, implementing data transmission channel between user equipments and a network which is corresponding to the first subscriber identity card to process the service request; the data transmission channel corresponding to at least two of the subscriber identity cards shares a common wireless connection. With the method, providing services for multiple cards at the same time can be available, meanwhile hardware cost and complexity is decreased, and wireless transmission resources is saved.

Claims

1. A service processing method for a multi-card user equipment, comprising:

when receiving a service request corresponding to a first subscriber identity card in the user equipment, implementing a first data transmission channel between the user equipment and a network corresponding to the first subscriber identity card to process the service request;

wherein a plurality of data channels correspond to a plurality of subscriber identity cards in the user equipment respectively, each of data transmission channels comprises one of the plurality of data channels and a wireless connection, the data transmission channels corresponding to at least two of the plurality of subscriber identity cards share a same wireless connection, and the same wireless connection is capable of being used by the at least two of the plurality of subscriber identity cards simultaneously.

2. The method according to claim 1, wherein all the data transmission channels corresponding to the plurality of subscriber identity cards share the same wireless connection.

3. The method according to claim 2, wherein the data transmission channels sharing the same wireless connection are established based on a common subscriber identity service access point.

4. The method according to claim 3, wherein the service comprises a basic service and a supplementary service;

the basic service comprises any one of registration service, voice service, video service, short message service or data service; and

the supplementary service comprises service which is obtained by supplementing or modifying the basic service.

5. The method according to claim 4, wherein the subscriber identity card establishing the first data transmission channel between the first subscriber identity card and the network is a subscriber identity card registered in an LTE network, when the service request is a VoLTE service request.

6. The method according to claim 4, wherein the subscriber identity card establishing the first data transmission channel between the first subscriber identity card and the network is a subscriber identity card registered in a Wi-Fi network, when the service request is a VoWiFi service request.

7. The method according to claim 3, wherein the service request is initiated by the first subscriber identity card or by the network.

8. The method according to claim 3, wherein the multi-card user equipment is in an idle state or a service processing state, when receiving the service request corresponding to the first subscriber identity card.

9. A multi-card user equipment, comprising:

a plurality of subscriber identity cards comprising a first subscriber identity card;

a data transmission channel establishment circuitry; and

a service processing circuitry,

wherein the data transmission channel establishment circuitry is configured to;

establish data transmission channels between the user equipment and a network, wherein each of the data transmission channels comprises a data channel and a wireless connection, the data channels of the data transmission channels correspond to the plurality of subscriber identity cards respectively, the data transmission channels corresponding to at least two of the plurality of subscriber identity cards share a same wireless connection, and the same wireless connection is capable of being used by the at least two of the plurality of subscriber identity cards simultaneously; and

wherein the service processing circuitry is configured to;

when receiving a service request corresponding to the first subscriber identity card, implement the data transmission channel between the user equipment and the network corresponding to the first subscriber identity card to process the service request.

10. The multi-card user equipment according to claim 9, wherein all the data transmission channels corresponding to the plurality of subscriber identity cards share the same wireless connection.

11. The multi-card user equipment according to claim 10, wherein the data transmission channels sharing the same wireless connection are established based on a common subscriber identity service access point.

12. The multi-card user equipment according to claim 11, wherein the service comprises:

a basic service and a supplementary service the basic service comprises any one of registration service, voice service, video service, short message service or data service;

the supplementary service comprises service which is obtained by supplementing or modifying the basic service.

13. The multi-card user equipment according to claim 12, wherein when the service request is a VoLTE service request, the subscriber identity card establishing the data transmission channel between the first subscriber identity card and the network is a subscriber identity card registered in an LTE network.

14. The multi-card user equipment according to claim 12, wherein when the service request is a VoWiFi service request, the subscriber identity card establishing the data transmission channel between the first subscriber identity card and the network is a subscriber identity card registered in a Wi-Fi network.

15. The multi-card user equipment according to claim 11, wherein the service request is initiated by the first subscriber identity card or by the network.

16. The multi-card user equipment according to claim 11, wherein when receiving the service request corresponding to the first subscriber identity card, the multi-card user equipment is in an idle state or service processing state.
