Subscriber Identification Modules (SIMs) associate mobile communication devices with subscriptions for voice and data communication services. A user having two or more mobile communication devices which are not multi-SIM capable mobile devices needs to use each of the mobile devices independently and so loses the flexibility of having a multi-SIM mobile device.
Conventional mobile communication devices may allow switching between SIM profiles by physically switching SIMs; in this case only one SIM profile on the device will be active at a time. Other devices may make a single SIM available to mobile communication devices that otherwise do not have a SIM. However, the single SIM can only be active on one device at a time.
Apparatuses and methods for multi-SIM multi-subscription functionality by remote sharing of SIM profile information between mobile communication devices are provided.
According to various embodiments there is provided a method for multi-Subscriber Identity Module (SIM) operation on a mobile communication device. The method may include: activating, in a first mobile communication device having a local SIM profile, a client module configured to obtain SIM profile information from a SIM profile of a second mobile communication device; sending a short range communication (SRC) signal to the second mobile communication device causing the second mobile communication device to activate a server module configured to share the SIM profile information of the SIM profile for the second mobile communication device with the first communication device; remotely accessing the shared SIM profile information of the shared SIM profile by the first mobile communication device; and operating the first mobile communication device in a multi-SIM mode using SIM profile information of the local SIM profile and the shared SIM profile information.
According to various embodiments there is provided a mobile communication device. The mobile communication device may include: a short range communication (SRC) unit; a client module configured to communicate via the SRC unit with one or more other mobile communication devices to obtain Subscriber Identity Module (SIM) profile information; and a network communications unit configured to communicate with a communication network associated with SIM profile information of the mobile communication device and with a communication network associated with the obtained SIM profile information.
According to various embodiments there is provided a method for multi-Subscriber Identity Module (SIM) call handling with a shared SIM profile. The method may include: when an incoming call is received on a subscription associated with a local SIM profile: determining whether to disassociate the shared SIM profile from a client device; if a determination is made to disassociate the shared SIM profile, unregistering the shared SIM profile from the client device and conducting the call on the subscription associated with the local SIM; and re-associating the shared SIM profile with the client device when the call on the local SIM is terminated.
According to various embodiments there is provided a method for sharing Subscriber Identity Module (SIM) profile information. The method may include: receiving, at a server device, an association request from a client device via a short range communication (SRC) signal; sending an access grant via an SRC signal to the client device; and making the SIM profile information of the one or more shared SIM profiles remotely available to the client device.

The control unit 110 may be configured to control overall operation of the mobile communication device 100 including control of the network communications unit 120, the SRC unit 125, the user interface device 170, and the storage 180. The control unit 110 may be a programmable device, for example, but not limited to, a microprocessor or microcontroller.
The control unit 110 may include a client module 112 configured to communicate with one or more other mobile communication devices to obtain SIM profile information, and a server module 114 configured to communicate with one or more other mobile communication devices to provide SIM profile information. The client module 112 and/or the server module 114 may be implemented as executable operations programmed into the control unit 110. Alternatively or additionally, the client module 112 and/or the server module 114 may be implemented as electronic circuitry separate from the control unit 110 and/or application-specific circuitry included within the control unit 110. The client module 112 may supply support for multi-SIM (i.e., multi-subscription) operation.
The storage 180 may be configured to store application programs necessary for operation of the mobile communication device 100 that are executed by the control unit 110, as well as application data and user data.
In various embodiments, two or more mobile communication devices that are not multi-SIM capable, i.e., each mobile communication device may physically accommodate only one SIM, may be associated to achieve multi-SIM functionality on one of the mobile communication devices that is selected to be a simulated-multi SIM device.
The client device 210 may be configured with a local SIM (also referred to herein as a client SIM) 212, and may have support, for example, but not limited to, software and/or firmware known to those of skill in the art, for multi-SIM (i.e., multi-subscription) capability. The server device 220 may be configured with a SIM (also referred to herein as a shared SIM) 222.
The client device 210 and the server device 220 may be linked via a wireless communication link 230 (e.g., via the SRC 125) using personal area network protocols, for example, NFC, Bluetooth®, Bluetooth Smart®, wireless USB, Wi-Fi®, Wi-Fi Direct®, LTE Direct, ANT+, ZigBee®, infrared (IrDA), etc., to enable sharing of SIM profile information, for example, but not limited to, user subscription information, user identity information and security information. The shared SIM profile information may be made remotely available by the server device 220 to the client device 210 permitting the client device 210 to operate as a multi-SIM device utilizing the services (e.g., voice call, data call, SMS, contact list, calendar, etc.) supported by the SIM profile of the shared SIM 222 as well as the services of the client SIM 212.
Supplementary services of the server device 220, for example, but not limited to, call forwarding, call waiting, etc., may be enabled and/or disabled via the client device 210 without affecting services on the client device 210.
When SIM profile information is shared, the server device 220 may disable its own access to the shared SIM profile of the shared SIM 222 and the SIM profile of the shared SIM 222 may be registered to the client device 210 to avoid duplicate registration of the SIM profile. The client device 210 may maintain communication with the server device 220 to access the shared SIM profile information of the shared SIM 222 for network connectivity and other features and/or capabilities of the shared SIM profile that are within the capabilities of the client device 210.
The shared SIM profile information of the shared SIM 222 may enable the client device 210 to communicate with a second communication network 195 via a second subscription 197 according to the shared SIM profile information from the server SIM 222. The second communication network 195 may be operated by the same or different service provider as the first communication network 190 and/or may support the same or different RATs, for example, but not limited to, WCDMA, GSM, GERAN, LTE, WiFi®, etc.
In some embodiments, the client device 210 may include more than one SIM and may be a Multi-SIM, Multi-Standby (MSMS) or a Multi-SIM, Multi-Active (MSMA) device. The multi-SIM client device 210 may have support, for example, but not limited to, software and/or firmware known to those of skill in the art, for multi-SIM (i.e., multi-subscription) capability using one or more shared SIM profiles from a server device 220.
In some embodiments the server device 220 may be a multi-SIM device and may share SIM profile information from more than one SIM with a client device 210. The SIM profiles to be shared by the server device 220 may be determined by presetting selectable options by, for example, but not limited to, input to the input device 172 based on options displayed on the display device 174 on the user interface device 170.
In some embodiments, the server device 220 may be a data card having a modem and a SIM that provides network connectivity or a portable computer having a SIM that provides network connectivity.
In some embodiments, both of the mobile communication devices may be multi-SIM devices having a client module 112 and a server module 114. One of the multi-SIM devices may be configured to operate as a server device 220 by activating the server module 114 to share SIM profile information of one or more SIMs with a another multi-SIM device operating as a client device 210 by activating the client module 112. The SIM profiles to be shared by the server device 220 may be determined by selectable options by, for example, but not limited to, input to the input device 172 based on options displayed on the display device 174 on the user interface device 170 and configuration during device set-up.
In some embodiments, both of the mobile communication devices may be multi-SIM devices having a client module 112 and a server module 114. Each mobile communication device may operate both as a client device 210 and a server device 220 by activating both the client module 112 and the server module 114 in each device will communication. Each mobile communication device may share SIM profile information from one or more SIMs with the other mobile communication device while maintaining operation with at least one unshared SIM that remains registered to each mobile communication device. The SIM profiles to be shared may be determined by presetting selectable options by, for example, but not limited to, input to the input device 172 based on options displayed on the display device 174 on the user interface device 170 and configuration during device set-up.
The control unit 110 of the client device 210 may provide a manual option to activate the client module 112 based on, for example, but not limited to, selecting a menu option using the input device 172 from a menu provided on the display device 174 of the user interface device 170, pressing a dedicated button or key on the input device 172, etc. Upon activation of the client module 112, the control unit 110 of the client device 210 may initiate a discovery process, for example, but not limited to, a peer-to-peer discovery process known in the art, to detect the server device 220 (320). If a server device 220 is not detected (330-N), the control unit 110 may cause the client module 112 to be deactivated (340).
When the server device 220 is detected (330-Y), the control unit 110 of the client device 210 may cause a request signal to be sent to the server device 220 to activate the server module 114 of the server device 220 and associate with the client device 210 (350). The client device 210 may receive a signal from the server device 220 granting access to one or more SIM profiles of the server device 220 (360). Alternatively, if the server device 220 had a previous association with the client device 210, the control unit 110 of the client device 210 may cause the client device 210 to be automatically associated with the server device 220 if the devices are in SRC proximity to each other (370). Both the client device 210 and the server device 220 may provide an indication, for example, an audio or visual indication, of the automatic association. One of ordinary skill in the art will appreciate that various indicators may be provided without departing from the scope of the present inventive concept.
When the client device 210 is associated with the server device 220, the control unit 110 may cause the client device 210 to register the shared SIM profile of the shared SIM 222 to itself (380) and remotely access the SIM profile information of the shared SIM 222 made available from the server device 220 as required for network connectivity and other features and/or capabilities of the shared SIM profile (390). The SIM profile information may be shared wirelessly by, for example, but not limited to, NFC, Bluetooth®, Bluetooth Smart®, wireless USB, WiFi®, Wi-Fi Direct®, LTE Direct, ANT+, ZigBee®, infrared (IrDA), or any other personal area network (PAN) protocol. Accordingly, the client device 210 may be operated in a multi-SIM mode using SIM profile information of the local SIM profile of the client/local SIM 212 and the shared SIM profile of the shared SIM 222.
In some embodiments, the method 300 may be carried out by one client device 210 to associate with a plurality of server devices 220 to share a plurality of SIM profiles. In some embodiments, the method 300 may be carried out by one client device 210 to share a plurality of SIM profiles provided by one server device 220.
The server device 220 may activate the server module 114 (450), unregister the SIM profile to be shared (460), and deactivate its own access to the SIM profile to be shared with the client device 210 (470). The server device 220 may make the SIM profile information of the shared SIM 222 available to the client device 210 for remote access (480). The SIM profile information may be shared wirelessly by, for example, but not limited to, NFC, Bluetooth®, Bluetooth Smart®, wireless USB, WiFi®, Wi-Fi Direct®, LTE Direct, ANT+, ZigBee®, infrared (IrDA), or any other personal area network (PAN) protocol.
If the server device 220 has been previously associated with the client device 210 (420-Y), the server device 220 may associate with the client device 210 (490). The server device 220 may associate with the client device 210. Alternatively, the client device 210 and/or the server device 220 may prompt a user to associate the server device 220 with the client device 210.
The server device 220 may unregister the SIM profile of the shared SIM 222 (460), and deactivate its own access to the SIM profile of the shared SIM 222 (470). The server device 220 may then make the SIM profile information of the shared SIM 222 available to the client device 210 for remote access (480). The SIM profile information may be shared wirelessly by, for example, but not limited to, NFC, Bluetooth®, Bluetooth Smart®, wireless USB, WiFi®, Wi-Fi Direct®, LTE Direct, ANT+, ZigBee®, infrared (IrDA), or any other personal area network (PAN) protocol.
If a determination to disassociate with the shared SIM 222 is made (520-Y), the control unit 110 of the client device 210 may unregister the SIM profile of the shared SIM 222 from the client device 210 (525) and send a notification signal to the server device 220 to re-register the SIM profile of the shared SIM 222 to the server device 220 (530). The incoming call on the client SIM 212 may then be conducted (535). If the control unit 110 determines that the call has not been terminated (540-N), the control unit 110 may cause the client device 210 to maintain the call on the client SIM 212 (535).
If the control unit 110 determines that the call on the client SIM 212 has been terminated (540-Y), the control unit 110 may cause the client device 210 to re-associate (e.g., automatically) with the server device 220 to share the SIM profile of the shared SIM 222 (545) and may continue to monitor the activity of the client SIM 212 and the shared SIM 222 (510).
If an incoming call is received on the client SIM (515-Y) and a determination is made by the control unit 110 of the client device 210 not to disassociate with the shared SIM 222 (520-N), the shared SIM 222 may remain available to perform local operations not requiring network connectivity, for example, but not limited to, contact list, calendar, etc., supported by the SIM profile of the shared SIM 222 (550), while the call is conducted on the client SIM 212 (555).
If the control unit 110 determines that the call has not been terminated (560-N), the control unit 110 may cause the client device 210 to maintain the call on the client SIM 212 (555). If the control unit 110 determines that the call on the client SIM 212 has been terminated (560-Y), the control unit 110 may continue to monitor the activity of the client SIM 212 and the shared SIM 222 (510).
If an incoming call is received on the shared SIM 222 (610-Y), the control unit 110 of the client device 210 may determine whether to disassociate with the shared SIM 222 (615). If a determination is made not to disassociate with the shared SIM 222 (615-N), the client device 210 may conduct the call on the shared SIM 222 (620). Since the client device 210 is an MSMA device, an incoming call may be received on the client SIM 212 during an active call on the shared SIM 222.
If an incoming call is received on the client SIM 212 (625-Y), the control unit 110 of the client device 210 may determine whether to disassociate with the shared SIM 222 (630). If a determination is made not to disassociate with the shared SIM 222 (630-N), the control unit 110 may cause the user interface device 170 to provide a call waiting and/or missed call indication (690). One of ordinary skill in the art will appreciate that the provided indication may be any type of audio and/or video indication.
If a determination is made to disassociate with the shared SIM 222 (630-Y), for example, to continue the active call on the shared SIM 222 using the server device 220, the control unit 110 of the client device 210 may unregister the shared SIM 222 form the client device 210 (635) and may notify the server device 220 to re-register the shared SIM 222 (640). The server device 220 may re-register the shared SIM 222 and the active call on the shared SIM 222 may be conducted on the server device 220 (645).
If the call on the client SIM 212 has not been terminated (650-N), the server device 220 may maintain the call on the client SIM 212 (645). If the call on the client SIM 212 has been terminated (650-Y), the control unit 110 of the client device 210 may cause the client device 210 to re-associate (e.g., automatically) with the server device 220 to share the SIM profile of the shared SIM 222 (655). The client device 210 may continue to monitor the activity of the client SIM 212 and the shared SIM 222 (510).
If a call is not received on the client SIM 212 while a call is conducted on the shared SIM 222 (625-N) and the call on the shared SIM 222 has not been terminated (685-N), the client device 210 may maintain the call on the shared SIM 222 (620). If the call on the shared SIM 222 has been terminated (685-Y), the client device 210 may continue to monitor the activity of the client SIM 212 and the shared SIM 222 (510).
If an incoming call is received on the shared SIM 222 (610-Y) and a determination is made to disassociate with the shared SIM 222 (615-Y), for example, to conduct the incoming call on the shared SIM 222 using the server device 220, the control unit 110 of the client device 210 may unregister the shared SIM 222 from the client device 210 (660) and may notify the server device 220 to re-register the shared SIM 222 (665). The server device 220 may re-register the shared SIM 222 and the incoming call on the shared SIM 222 may be conducted on the server device 220 (670).
If the call on the shared SIM 222 has not been terminated (675-N), the server device 220 may maintain the call on the shared SIM 222 (670). If the call on the shared SIM 222 has been terminated (675-Y), the server device 220 may re-associate (e.g., automatically) with the client device 210 to share the SIM profile of the shared SIM 222 (680). The client device 210 may continue to monitor the activity of the client SIM 212 and the shared SIM 222 (510).
If an incoming call is received on the shared SIM 222 (710-Y), the control unit 110 of the client device 210 may determine whether to disassociate with the shared SIM 222 (715). If a determination is made not to disassociate with the shared SIM 222 (715-N), the client device 210 may conduct the call on the shared SIM 222 (720). Since the client device 210 is an MSMS device, only one of the client SIM 212 and the shared SIM 222 may be active at any time. The control unit 110 of the client device 210 may determine if the call on the shared SIM 222 has been terminated (725).
If the call on the shared SIM 222 has not been terminated (725-N), the client device 210 may maintain the call on the shared SIM 222 (720). If the call on the shared SIM 222 has been terminated (725-Y), the client device 210 may continue to monitor the activity of the client SIM 212 and the shared SIM 222 (510).
If a determination is made to disassociate with the shared SIM 222 (715-Y), for example, to conduct the incoming call on the shared SIM 222 using the server device 220, the control unit 110 of the client device 210 may unregister the shared SIM 222 from the client device 210 (730) and may notify the server device 220 to re-register the shared SIM 222 (735). The server device 220 may re-register the shared SIM 222 and the incoming call on the shared SIM 222 may be conducted on the server device 220 (740).
If the call on the shared SIM 222 has not been terminated (745-N), the server device 220 may maintain the call on the shared SIM 222 (740). If the call on the shared SIM 222 has been terminated (745-Y), the server device 220 may re-associate (e.g., automatically) with the client device 210 to share the SIM profile of the shared SIM 222 (750). The client device 210 may continue to monitor the activity of the client SIM 212 and the shared SIM 222 (510).
In some embodiments, the methods 500, 600, 700 may be carried out by one client device 210 to associate with a plurality of server devices 220 to share a plurality of SIM profiles. In some embodiments, the methods 500, 600, 700 may be carried out by one client device 210 to share a plurality of SIM profiles provided by one server device 220.
In some embodiments, a SIM profile of an embedded SIM that cannot be removed from a mobile communication device 100 may be shared with a client in a diagnostic mode to investigate problems with the embedded SIM.
