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.

First claim

What is claimed is:

1 . A multi-card user equipment service processing method, comprising:
when receiving the service request corresponding to the first subscriber identity card, implementing a data transmission channel between the user equipment and a network corresponding to a first subscriber identity card to process a service request; wherein the data transmission channel comprises a data channel and a wireless connection, the data channel corresponds to multiple subscriber identity cards comprised in the user equipment one by one, and a data transmission channel corresponding to at least two of the subscriber identity cards share a common wireless connection.

2 . The method according to claim 1 , wherein all the data transmission channels corresponding to the multiple subscriber identity cards share a common wireless connection.

3 . The method according to claim 2 , wherein the data transmission channel sharing a common wireless connection is 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 includes services relevant to supplementing or modifying the basic service.

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

6 . The method according to claim 4 , wherein the subscriber identity card establishing a 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 based on the first subscriber identity card, or by the network.

8 . The method according to claim 3 , wherein the multi-card user equipment is in a 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:
multiple subscriber identity cards comprising a first subscriber identity card; a data transmission channel establishment circuitry; and a service processing circuitry; wherein the first subscriber identity card is an user identification card corresponding to a service request;
wherein the data transmission channel establishment circuitry, is configured to:
establish a data transmission channel between the user equipment and a network, wherein the data transmission channel comprises a data channel and a wireless connection, the data channel corresponds to the multiple subscriber identity cards one by one, and a data transmission channel corresponding to at least two of the subscriber identity cards share a common wireless connection; and

wherein the service processing circuitry, is configured to:
when receiving a service request corresponding to the first subscriber identity card, implement a 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 correspond to the multi-cards share a common wireless connection.

11 . The multi-card user equipment according to claim 10 , wherein the data transmission channel sharing a common wireless connection is 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 includes services relevant to 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 data transmission channel between the first subscriber identity card and the network is a subscriber identity card registered in a 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 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 based on 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 idle state or service processing state.
