Communication system, mobile communication apparatus and switching method of subscriber identification information
First Claim
1. A communication system, suitable for a mobile telecom network, the communication system comprising:
- a first mobile communication device comprising a first subscriber identification card, the first mobile communication device being configured to access the mobile telecom network according to first subscriber identification information within the first subscriber identification card, the mobile telecom network comprising a home location register, which corresponds to the first mobile communication device and stores the first subscriber identification information; and
a second mobile communication device communicatively connected to the mobile telecom network, the second mobile communication device being operated to send a request instruction to the mobile telecom network, the mobile telecom network verifying the request instruction, selectively duplicating the first subscriber identification information stored in the home location register and sending the duplicated first subscriber identification information to the second mobile communication device,wherein, when the request instruction passes the verification, the home location register or the first mobile communication device further transmits a contact list, a message record, a call record or an encryption key to the second mobile communication device.

Abstract
A communication system, a mobile communication apparatus and a switching method of subscriber identification information are disclosed. The switching method includes following steps. First subscriber identification information of a first subscriber identification card is stored into a home location register (HLR) of a mobile telecom network by a first mobile communication device. A request instruction is sent by a second mobile communication device. The request instruction is verified by the mobile telecom network. If the request instruction passes the verification, the first subscriber identification information is duplicated and transmitted to the second mobile communication device.
