Abstract
A method for updating mobile communication parameters including providing a complimentary subscriber identity module (dual-sided UICC) between an interface between a primary subscriber identity module and a terminal of a mobile device, wherein the dual-sided UICC intercepts requests for communication from the primary SIM and determines whether a communications service should proceed with the dual-sided UICC or via the primary SIM. Upon a condition in which the communications service proceeds via the dual-sided UICC, the method includes detecting a change in location of the mobile device and updating one or more parameters on the dual- sided UICC before reinitializing the mobile device with the updated one or more parameters.
Description
METHOD AND SYSTEM FOR PROVIDING OVER-THE-AIR MOBILE DEVICE
PARAMETER UPDATES
FIELD OF INVENTION
100011 The present invention relates to the field of mobile device communications, and more particularly to a method and system for providing over-the-air parameter updates for mobile devices.
BACKGROUND OF THE INVENTION
[00021 Mobile telephone calls made when outside a user's home network generally incur roaming charges that can become extremely costly. Typical mobile telephones have a SIM
(subscriber identity module) card used to identify the user and the base network to which the user belongs. Often times, user's attempting to avoid roaming charges will acquire secondary services directly from a foreign service provider, such as by purchasing a second SIM card and substituting the second SIM card for the primary one when in a roaming zone. Alternative solutions include providing special roaming access telephone numbers to route calls through service providers offering discounted rates, however this requires the user to dial extra digits prior to completing each telephone call and to remember these access numbers when travelling. Other users simply rely on calling cards which do save money for outgoing calls, but are not compatible or helpful with incoming calls. Indeed, a user has little or no control over incoming calls and the charges incurred when receiving a call in a roaming zone, other than to ignore the call altogether. Similar problems are encountered with data communications and accessing Internet services (as well as SMS service) when in a roaming zone, particularly as smart phones become more widely used, such as for a travel aid either for leisure and tourist travel or for business travelers. Data communications generally cannot be accessed at discounted roaming rates by way of special access roaming telephone numbers or by calling cards.
DOCMANAGE_LEGAL_676281.1 [0003] One solution to these prior art problems has been proposed by applicant's currently pending PCT International Application No. PCT/CA2011/050379 where there is disclosed the structure and use of a complimentary SIM card, and more generally a complementary dual-sided UICC card, that is employed concurrently with a primary SIM card in a manner such that the complementary dual-sided UICC and primary SIM cards are effectively structurally and functionally coupled when in a phone.
The complimentary SIM of the `379 application permits for advanced call and data routing where appropriate while still allowing the primary SIM to control voice and data when a user is in their home network.
[0004] One problem associated with the invention of the `379 application, and indeed with other systems that attempt to employ virtual SIM technologies is there are a large number of mobile service operators that can be provisioned to a roaming user's SIM card with communication parameters that can change over time. Currently, when these parameters change, a new SIM card is required, or in the case of the solution described `379 patent and other similar solutions, a new complementary SIM card would be required.
SUMMARY OF THE INVENTION
[0005] According to one embodiment of the invention, there is provided a method for updating mobile communication parameters in a complimentary dual-sided UICC which is inserted between a primary subscriber identity module (SIM) and a mobile terminal device, wherein the complimentary dual-sided UICC intercepts requests for communication from the primary SIM and determines whether a communications service should proceed with the complimentary dual-sided UICC or via the primary SIM; upon a condition in which the communications service proceeds via the complimentary dual-sided UICC card, detecting a change in location of the mobile device and updating one or more DOCMANAGE_LEGAL_676281.1 parameters on the dual-sided UICC; and, reinitializing the mobile device with the updated one or more parameters.
[0006] According to one aspect of the invention, the updating one or more parameters further includes generating by the dual-sided UICC a location update data packet (USSD or SMS
message) containing information indicative of a mobile country code (MCC) of visited network, a mobile network code (MNC) of visited network and a dual-sided UICC card identifier number; sending the proprietary location update packet to an application server; generating by the application server the one or more parameters; and, sending those parameters to the dual-sided UICC card.
[0007] According to another aspect of the invention, the sending step comprises sending via SMS or USSD messaging. Messages are generated by the dual-sided UICC card and are sent via an application toolkit command, for example. Those commands may be described by ISO, 3GPP and ETSI
standardization groups.
[0008] According to another aspect of the invention, the SMS or USSD messaging includes encryption of the user data in the message.
[0009] According to another aspect of the invention, the dual-sided UICC
comprises an application for adopting the one or more parameters which are sent by the dual-sided UICC card or received from the application server.
[00010] According to another aspect of the invention, delivered proprietary messages include one or more selected from group comprising an IMSI number, an authentication key, a DID number, an LNS
number, an SMS-C number, dialing mode with the provisioned IMSI, and flags enabling or disabling various mobile services in the region serviced by the provisioned IMSI number.
[00011] According to another aspect of the invention, the sending step comprises sending via a mobile base station operated by a roaming network service provider.

BRIEF DESCRIPTION OF THE DRAWINGS
[00021] The invention will now be described in more detail, by way of example only, with reference to the accompanying drawings, in which like numbers refer to like elements, wherein:
[00022] Figure 1 shows one system in which the method of the invention may be implemented.
[00023] Figure 2 shows a network arrangement in which the method may be implemented.
[00024] Figure 3 is a flowchart showing one embodiment of the method according to the invention.
DETAILED DESCRIPTION OF THE INVENTION
[00025] The preferred embodiment of the invention is implemented with respect to a means for intercepting a request for communications service from a communications device. Examples of this means and its operation are described in the `379 application mentioned above, the contents of which are herein explicitly incorporated by reference. Referring now to Figure 1, there is shown a preferred system in which embodiments of the invention are implemented, in which a means for intercepting a request for communications service is provided to a mobile communications device in the form of a dual-sided UICC card 10 that fits into a terminal mobile device 20 and positioned between a SIM card 15 native to the phone (or alternatively to a user's home network), hereinafter referred to also as the DOCMANAG E_LEGAL_676281.1 primary SIM card 15, and an interface 25 between the mobile device 20 and the primary SIM card 15.
The dual-sided UICC card is also referred to as the complementary SIM card in the `379 application.
Accordingly, the terms dual-sided UICC and complementary SIM are used interchangeable herein and one skilled in the art will understand that a complementary SIM is one example of a dual-sided UICC
card that may be used.
[00026] In this manner, the dual-sided UICC card 10 is positioned to provide a physical link between the primary SIM card 15 and the interface 25 on the terminal mobile device 20 that would otherwise have interacted with the primary SIM card 15. The dual-sided UICC 10 is thin enough to fit into existing mobile devices between the primary SIM 15 and the phone interface 25. Communication between the terminal mobile device and dual-sided UICC may be performed according to the ISO, 3GPP and ETSI standards. At the same way performed communication between the dual-sided UICC
and the primary SIM card may use any one of ISO 7816-3/4 or 3GPP 51-011/51-standards. These terms and standards are known in the art, and accordingly are not described herein in further detail.
[00027] In use, a request for communications service occurs when a user places or receives a telephone call, sends or receives and SMS or attempts to access data services from a mobile device.
The user's requests are intercepted and routed by the dual-sided UICC, via a mobile network operator in the geographical region of where the user currently is (roaming country), to an application server.
The user's requests are routed to the application server in a manner that depends on the service type originating the request, although these would typically be by the dual-sided UICC sending SMS or USSD message further translated into an HTTP request to the application server.
[00028] The application server undertakes an authentication step to confirm the identity of the user and to ensure that the user, and therefore the dual-sided UICC, are registered with the service provider associated with the dual-sided UICC. The routing of the request to the application server may include DOC MANAG E_LEGAL_676281.1 a data packet that includes one or more selected from the following: a serial number, an International Mobile Subscriber Identity (IMSI) associated with the dual-sided UICC, an MSISDN (Mobile Subscriber Integrated Services Digital Network Number) associated with the dual-sided UICC, an MSISDN associated with the primary SIM, an associated DID (Direct Inward Dialing) number, a VSIM profile identification, the called phone number, the user's location, and various other data that may be useful in identifying and determining the intended destination of the request for communications. Various other data would be applicable may be included in the data packet for other types of communications services being requested. Authentication of the user may be based on a user data packet, referred to above and may further include a server-side identification using one or more of the following records: a unique account identification number, a call flow scenario identification number, a customer account number, an associated DID number, the mobile country code (MCC) of the primary SIM, the mobile network code (MNC) of the network operator of the primary SIM, the phone number associated with the user's device, a flag that indicates if the customer account is active, a flag that indicates if the customer account is a multi-user account, a code unique to the dual-sided UICC, a serial number associated with the dual-sided UICC, a phone number that belongs to the user's user profile, an MSISDN of the current virtual profile and a virtual SIM
profile identification. Once the user has been authenticated as being a customer of the service provider associated with the dual-sided UICC, the application server may proceed to providing authorization for the request for services.
Alternatively, if the user cannot be authenticated, the session is terminated.
Various ways of completing the call or request for data are possible.
(000291 In carrying out the above-described process flow, it will now be clear that certain parameters associated with the dual-sided UICC are required to interact with the application server and/or with a roaming partner with which the application server interacts, either directly or via the dual-sided UICC.
DOCMANAG E_LEGAL_676281.1 [000301 In order to provide flexibility and greater continuity to the use of the dual-sided UICC (or indeed to any other functionally equivalent physical or virtual device), applicant proposes the herein-described method for providing over the air updates of these certain parameters based on location updates identified by the dual-sided UICC. In particular, parameter updates are provided based on location updates since it is when a user changes locations, that is changes the network on which the mobile device is operating, that new network will attempt to authenticate the user's mobile terminal device (dual-sided UICC card) and if problems are encountered due to changes in the requirements of a network operator, or an altogether new network operator being in existence in the new location.
[000311 Accordingly, in one embodiment the invention provides for a method for using location updates to configure the parameters of the dual-sided UICC card. Broadly, location updates can be delivered from a mobile station to a network operator via SMS or USSD later translated into HTTP or MAP protocols, for example. Other protocols are also possible, and the invention is not to be considered limited to these. While various parameters may be communicated to the dual-sided UICC
for providing these over-the-air updates, the especially preferred parameters are the International Mobile Subscriber Identity (IMSI) and its corresponding authentication key (Ki), DID/LNS numbers for the arrangement of call forwarding, and SMS-C number(s) for the delivery of SMS messages. The general functionality, use and standards for these parameters are well known and accordingly not described in further detail herein.
[000321 For the purposes of this description, the term location updates is meant to encompass any signal, including data or otherwise, that gets communicated to and/or from a mobile device to a mobile station that includes information relating to a change in location of the mobile device, and particularly where the change in location requires the mobile device to access services via a different mobile station. Typical switching between available network operators as users travel between different service regions is well known in the art. Applicant provides for a method of updating parameters of DOCMANAG E_LEGAL_676281.1 the dual-sided UICC when a switch between network operators is detected, or alternatively, when the option of a switch between network operators becomes available to the mobile device.
[000331 In the preferred embodiment, location updates consist of a data packet containing information about a new, or alternatively updated, location of a mobile station. The data packet can be generated by the dual-sided USIM card though an SMS or USSD message to the operator.
Alternatively, the location update event can be registered by the operator's home location register (HLR) when the mobile device is being updated by the visiting network's visitor location register (VLR). HLR can also cause generation of a message to the application server that can trigger communication from the mobile station to the dual-sided USIM card. The location update event causes creation of the data packet that contains available information regarding the primary SIM and/or the complementary SIM card in the mobile device. The data packet is then sent to the an application server of the network operator of the newly detected mobile station and/or the application server of the dual-sided UICC provider. Any reference to a newly detected mobile station in this application applies equally to an already detected mobile station with newly detected updates or newly detected requirements.
[000341 The location update data packet sent from the mobile device preferably includes the dual-sided UICC card's IMSI number, the visitor mobile network country code (MCC) and the visitor mobile network code (MNC). For example, a mobile device user, having a mobile device, entering a new country will have generated by the dual-sided USIM card a data packet that communicates the IMSI of the dual-sided USIM card, the country code of where the IMSI is registered, and the network within that country of where the IMSI is registered. This provides sufficient information for the network operator in the new location to identify the user's SIM (primary or dual-sided UICC, as the case may be) and, along with the identification code IMSI and Ki that may be communicated with the location update data packet or separately, authenticate the mobile device on the new network.
DOC MANAG E_LEGA L_676281.1 [00035] In the case of the dual-sided UICC being used to authenticate the mobile device, and subsequently initiate voice or data messaging, the invention provides for updated parameters to be sent to the dual-sided UICC (with SMS-PP-DD message) that provide for the ability to communicate with the newly found network. In prior art systems, where the dual-sided UICC is not being used, if a newly formed (or recently updated) network is discovered by the mobile device, but the service provider of the SIM has not provided authentication information for the newly found network, the mobile device will not be able to be authenticated on the new network.
According to the invention, this type of authentication information can be updated over the air for the dual-sided UICC, such that the dual-sided UICC is able to provide an optimal location update data packet to the new network. An optimal location update data packet would be one that permits that dual-sided UICC to communicate with a network providing any one of the most cost effective, fastest and/or most secure network available, even if this network requires parameters that are not pre-installed on the dual-sided UICC.
[00036] Referring now to Figure 2, there is shown a network arrangement according to one embodiment of the invention. The mobile device 205, includes a primary SIM and a dual-sided UICC
210. The mobile device 205 is in communication with a mobile base station 215 for accessing the services of a local network operator 220. The network operator 220 communicates with mobile networks around the world as is known in the art. In addition, however, the network operator 220 is also in communication with an application server 225 of the dual-sided UICC
service provider. In this arrangement, updated parameters can be pushed to the dual-sided UICC by way of the application server 225 to the mobile base station 215 and finally to the dual-sided UICC.
In one embodiment, the updated parameters can be sent in the form of a data packet by either SMS or USSD protocols. Once a location update message is received by the application server 225, the application server 225 generates a new data package containing dual-sided UICC card updates based on the server's internal business logic. For example, the application server 225 may be programmed to identify a particular IMSI for DOCMANAG E_LEGAL_676281.1 the UICC card with better calling rates in the new location, or access to higher network bandwidth in the new location, typically a new country, and would then issue an SMS or USSD
with the new IMSI
and related authentication information, such as key Ki. In addition, if the mobile device requires a different SMS-C number from the one already provisioned to the phone, the application server 225 can issue a message containing the new SMS-C number. Finally, in order to enable incoming calls on the home phone number in the visited region, a DID or other local number may also be sent that can be used to enable call forwarding, for example.
[00037] The dual-sided UICC that is present in the mobile device will contain internal logic or an onboard application that permits it to make use of the data packet received from the application server (SMS-PP-DD) containing the new IMSI and related authentication information.
Upon receipt, and after authenticating that the received data packet was indeed received from the application server, the new parameters are adopted by the dual-sided UICC. Alternatively, the message may be send in an encrypted format, with decryption keys known only to the application server and to the dual-sided UICC.
[00038] One way of provisioning IMSI and related authentication information is illustrated in the flow chart of Figure 3. After recognition of the roaming location (typically country), the application on the dual-sided UICC sends a request to the application server (via SMS/USSD
or other service) for new network registration and authentication parameters. This request would typically include the location update packet such that the application server can use the information in the location update packet to identify preferred or optimal parameters for the new location. Once the application server executes its decision making application and identifies the optimal or preferred dual-sided UICC
parameters for the updated location, these parameters are delivered via SMS
messages to the complementary SIM. Once the dual-sided UICC application receives these parameters and executes its import logic, the UICC-ME interface of the mobile device is reinitialized (typically rebooted -DOCMANAG E_LEGAL_676281.1 reboot command related to the UICC-ME protocol described in ISO/3GPP
specifications) so that the updated parameters of the dual-sided UICC can be registered in the new location network.
[00039] When delivering new registration and authentication parameters, a new SMS-C number is typically also delivered to the dual-sided UICC from the application server.
Once updated and reinitialized, the new SMS-C number is in used by the mobile device (re-initialization process and behavior of the mobile terminal device is specified according to the 3GPP/ETSI
standard, for example). The SMS-C number can be provisioned remotely in a manner similar to that described above with respect to the UICC parameters.
[00040] In addition a DID number can also be sent to the dual-sided UICC upon receipt of the location update packet. This can be done to serve multiple purposes. For example, the number can be used for establishing call forwarding or providing the customer with a secondary number local to the region visited by the mobile station. In the case of call forwarding, a mobile station in communication with the dual-sided UICC sends a supplementary service (SS - specified by 3GPP) message to the home carrier of the primary SIM and redirects calls to a local number, thus allowing the delivery of incoming calls while roaming at no additional cost to the subscriber. While a local number in a visiting region allows calls at no charge from other local numbers in the visited region.
[00041] Example I
[00042] A user is in a roaming zone, and outside of the user's home country.
The dual-sided UICC
card is thus active. When the user enters a new roaming zone, the dual-sided UICC intercepts the request for service and sends either an SMS or USSD message containing location update data packet to the application server. The application server authenticates the user's identity, determines their location and the availability of a roaming partner, checks the account balance, and authorizes or rejects the request for service. The application server also identifies whether there are multiple possible roaming partners and whether preferred or optimal service can be obtained from a roaming partner via DOCMANAG E_LEGAL_676281.1 different IMSI, and related parameters on the dual-sided UICC card. If new parameters can be provisioned to provide a preferred service, the application server sends an SMS message back to the dual-sided UICC with the updated parameters, that are then imported into the dual-sided UICC and the mobile device reinitiated on the preferred network and/or with the preferred parameters.
[000431 This concludes the description of the presently preferred embodiments of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS
[00021] The invention will now be described in more detail, by way of example only, with reference to the accompanying drawings, in which like numbers refer to like elements, wherein:
[00022] Figure 1 shows one system in which the method of the invention may be implemented.
[00023] Figure 2 shows a network arrangement in which the method may be implemented.
[00024] Figure 3 is a flowchart showing one embodiment of the method according to the invention.
DETAILED DESCRIPTION OF THE INVENTION
[00025] The preferred embodiment of the invention is implemented with respect to a means for intercepting a request for communications service from a communications device. Examples of this means and its operation are described in the `379 application mentioned above, the contents of which are herein explicitly incorporated by reference. Referring now to Figure 1, there is shown a preferred system in which embodiments of the invention are implemented, in which a means for intercepting a request for communications service is provided to a mobile communications device in the form of a dual-sided UICC card 10 that fits into a terminal mobile device 20 and positioned between a SIM card 15 native to the phone (or alternatively to a user's home network), hereinafter referred to also as the DOCMANAG E_LEGAL_676281.1 primary SIM card 15, and an interface 25 between the mobile device 20 and the primary SIM card 15.
The dual-sided UICC card is also referred to as the complementary SIM card in the `379 application.
Accordingly, the terms dual-sided UICC and complementary SIM are used interchangeable herein and one skilled in the art will understand that a complementary SIM is one example of a dual-sided UICC
card that may be used.
[00026] In this manner, the dual-sided UICC card 10 is positioned to provide a physical link between the primary SIM card 15 and the interface 25 on the terminal mobile device 20 that would otherwise have interacted with the primary SIM card 15. The dual-sided UICC 10 is thin enough to fit into existing mobile devices between the primary SIM 15 and the phone interface 25. Communication between the terminal mobile device and dual-sided UICC may be performed according to the ISO, 3GPP and ETSI standards. At the same way performed communication between the dual-sided UICC
and the primary SIM card may use any one of ISO 7816-3/4 or 3GPP 51-011/51-standards. These terms and standards are known in the art, and accordingly are not described herein in further detail.
[00027] In use, a request for communications service occurs when a user places or receives a telephone call, sends or receives and SMS or attempts to access data services from a mobile device.
The user's requests are intercepted and routed by the dual-sided UICC, via a mobile network operator in the geographical region of where the user currently is (roaming country), to an application server.
The user's requests are routed to the application server in a manner that depends on the service type originating the request, although these would typically be by the dual-sided UICC sending SMS or USSD message further translated into an HTTP request to the application server.
[00028] The application server undertakes an authentication step to confirm the identity of the user and to ensure that the user, and therefore the dual-sided UICC, are registered with the service provider associated with the dual-sided UICC. The routing of the request to the application server may include DOC MANAG E_LEGAL_676281.1 a data packet that includes one or more selected from the following: a serial number, an International Mobile Subscriber Identity (IMSI) associated with the dual-sided UICC, an MSISDN (Mobile Subscriber Integrated Services Digital Network Number) associated with the dual-sided UICC, an MSISDN associated with the primary SIM, an associated DID (Direct Inward Dialing) number, a VSIM profile identification, the called phone number, the user's location, and various other data that may be useful in identifying and determining the intended destination of the request for communications. Various other data would be applicable may be included in the data packet for other types of communications services being requested. Authentication of the user may be based on a user data packet, referred to above and may further include a server-side identification using one or more of the following records: a unique account identification number, a call flow scenario identification number, a customer account number, an associated DID number, the mobile country code (MCC) of the primary SIM, the mobile network code (MNC) of the network operator of the primary SIM, the phone number associated with the user's device, a flag that indicates if the customer account is active, a flag that indicates if the customer account is a multi-user account, a code unique to the dual-sided UICC, a serial number associated with the dual-sided UICC, a phone number that belongs to the user's user profile, an MSISDN of the current virtual profile and a virtual SIM
profile identification. Once the user has been authenticated as being a customer of the service provider associated with the dual-sided UICC, the application server may proceed to providing authorization for the request for services.
Alternatively, if the user cannot be authenticated, the session is terminated.
Various ways of completing the call or request for data are possible.
(000291 In carrying out the above-described process flow, it will now be clear that certain parameters associated with the dual-sided UICC are required to interact with the application server and/or with a roaming partner with which the application server interacts, either directly or via the dual-sided UICC.
DOCMANAG E_LEGAL_676281.1 [000301 In order to provide flexibility and greater continuity to the use of the dual-sided UICC (or indeed to any other functionally equivalent physical or virtual device), applicant proposes the herein-described method for providing over the air updates of these certain parameters based on location updates identified by the dual-sided UICC. In particular, parameter updates are provided based on location updates since it is when a user changes locations, that is changes the network on which the mobile device is operating, that new network will attempt to authenticate the user's mobile terminal device (dual-sided UICC card) and if problems are encountered due to changes in the requirements of a network operator, or an altogether new network operator being in existence in the new location.
[000311 Accordingly, in one embodiment the invention provides for a method for using location updates to configure the parameters of the dual-sided UICC card. Broadly, location updates can be delivered from a mobile station to a network operator via SMS or USSD later translated into HTTP or MAP protocols, for example. Other protocols are also possible, and the invention is not to be considered limited to these. While various parameters may be communicated to the dual-sided UICC
for providing these over-the-air updates, the especially preferred parameters are the International Mobile Subscriber Identity (IMSI) and its corresponding authentication key (Ki), DID/LNS numbers for the arrangement of call forwarding, and SMS-C number(s) for the delivery of SMS messages. The general functionality, use and standards for these parameters are well known and accordingly not described in further detail herein.
[000321 For the purposes of this description, the term location updates is meant to encompass any signal, including data or otherwise, that gets communicated to and/or from a mobile device to a mobile station that includes information relating to a change in location of the mobile device, and particularly where the change in location requires the mobile device to access services via a different mobile station. Typical switching between available network operators as users travel between different service regions is well known in the art. Applicant provides for a method of updating parameters of DOCMANAG E_LEGAL_676281.1 the dual-sided UICC when a switch between network operators is detected, or alternatively, when the option of a switch between network operators becomes available to the mobile device.
[000331 In the preferred embodiment, location updates consist of a data packet containing information about a new, or alternatively updated, location of a mobile station. The data packet can be generated by the dual-sided USIM card though an SMS or USSD message to the operator.
Alternatively, the location update event can be registered by the operator's home location register (HLR) when the mobile device is being updated by the visiting network's visitor location register (VLR). HLR can also cause generation of a message to the application server that can trigger communication from the mobile station to the dual-sided USIM card. The location update event causes creation of the data packet that contains available information regarding the primary SIM and/or the complementary SIM card in the mobile device. The data packet is then sent to the an application server of the network operator of the newly detected mobile station and/or the application server of the dual-sided UICC provider. Any reference to a newly detected mobile station in this application applies equally to an already detected mobile station with newly detected updates or newly detected requirements.
[000341 The location update data packet sent from the mobile device preferably includes the dual-sided UICC card's IMSI number, the visitor mobile network country code (MCC) and the visitor mobile network code (MNC). For example, a mobile device user, having a mobile device, entering a new country will have generated by the dual-sided USIM card a data packet that communicates the IMSI of the dual-sided USIM card, the country code of where the IMSI is registered, and the network within that country of where the IMSI is registered. This provides sufficient information for the network operator in the new location to identify the user's SIM (primary or dual-sided UICC, as the case may be) and, along with the identification code IMSI and Ki that may be communicated with the location update data packet or separately, authenticate the mobile device on the new network.
DOC MANAG E_LEGA L_676281.1 [00035] In the case of the dual-sided UICC being used to authenticate the mobile device, and subsequently initiate voice or data messaging, the invention provides for updated parameters to be sent to the dual-sided UICC (with SMS-PP-DD message) that provide for the ability to communicate with the newly found network. In prior art systems, where the dual-sided UICC is not being used, if a newly formed (or recently updated) network is discovered by the mobile device, but the service provider of the SIM has not provided authentication information for the newly found network, the mobile device will not be able to be authenticated on the new network.
According to the invention, this type of authentication information can be updated over the air for the dual-sided UICC, such that the dual-sided UICC is able to provide an optimal location update data packet to the new network. An optimal location update data packet would be one that permits that dual-sided UICC to communicate with a network providing any one of the most cost effective, fastest and/or most secure network available, even if this network requires parameters that are not pre-installed on the dual-sided UICC.
[00036] Referring now to Figure 2, there is shown a network arrangement according to one embodiment of the invention. The mobile device 205, includes a primary SIM and a dual-sided UICC
210. The mobile device 205 is in communication with a mobile base station 215 for accessing the services of a local network operator 220. The network operator 220 communicates with mobile networks around the world as is known in the art. In addition, however, the network operator 220 is also in communication with an application server 225 of the dual-sided UICC
service provider. In this arrangement, updated parameters can be pushed to the dual-sided UICC by way of the application server 225 to the mobile base station 215 and finally to the dual-sided UICC.
In one embodiment, the updated parameters can be sent in the form of a data packet by either SMS or USSD protocols. Once a location update message is received by the application server 225, the application server 225 generates a new data package containing dual-sided UICC card updates based on the server's internal business logic. For example, the application server 225 may be programmed to identify a particular IMSI for DOCMANAG E_LEGAL_676281.1 the UICC card with better calling rates in the new location, or access to higher network bandwidth in the new location, typically a new country, and would then issue an SMS or USSD
with the new IMSI
and related authentication information, such as key Ki. In addition, if the mobile device requires a different SMS-C number from the one already provisioned to the phone, the application server 225 can issue a message containing the new SMS-C number. Finally, in order to enable incoming calls on the home phone number in the visited region, a DID or other local number may also be sent that can be used to enable call forwarding, for example.
[00037] The dual-sided UICC that is present in the mobile device will contain internal logic or an onboard application that permits it to make use of the data packet received from the application server (SMS-PP-DD) containing the new IMSI and related authentication information.
Upon receipt, and after authenticating that the received data packet was indeed received from the application server, the new parameters are adopted by the dual-sided UICC. Alternatively, the message may be send in an encrypted format, with decryption keys known only to the application server and to the dual-sided UICC.
[00038] One way of provisioning IMSI and related authentication information is illustrated in the flow chart of Figure 3. After recognition of the roaming location (typically country), the application on the dual-sided UICC sends a request to the application server (via SMS/USSD
or other service) for new network registration and authentication parameters. This request would typically include the location update packet such that the application server can use the information in the location update packet to identify preferred or optimal parameters for the new location. Once the application server executes its decision making application and identifies the optimal or preferred dual-sided UICC
parameters for the updated location, these parameters are delivered via SMS
messages to the complementary SIM. Once the dual-sided UICC application receives these parameters and executes its import logic, the UICC-ME interface of the mobile device is reinitialized (typically rebooted -DOCMANAG E_LEGAL_676281.1 reboot command related to the UICC-ME protocol described in ISO/3GPP
specifications) so that the updated parameters of the dual-sided UICC can be registered in the new location network.
[00039] When delivering new registration and authentication parameters, a new SMS-C number is typically also delivered to the dual-sided UICC from the application server.
Once updated and reinitialized, the new SMS-C number is in used by the mobile device (re-initialization process and behavior of the mobile terminal device is specified according to the 3GPP/ETSI
standard, for example). The SMS-C number can be provisioned remotely in a manner similar to that described above with respect to the UICC parameters.
[00040] In addition a DID number can also be sent to the dual-sided UICC upon receipt of the location update packet. This can be done to serve multiple purposes. For example, the number can be used for establishing call forwarding or providing the customer with a secondary number local to the region visited by the mobile station. In the case of call forwarding, a mobile station in communication with the dual-sided UICC sends a supplementary service (SS - specified by 3GPP) message to the home carrier of the primary SIM and redirects calls to a local number, thus allowing the delivery of incoming calls while roaming at no additional cost to the subscriber. While a local number in a visiting region allows calls at no charge from other local numbers in the visited region.
[00041] Example I
[00042] A user is in a roaming zone, and outside of the user's home country.
The dual-sided UICC
card is thus active. When the user enters a new roaming zone, the dual-sided UICC intercepts the request for service and sends either an SMS or USSD message containing location update data packet to the application server. The application server authenticates the user's identity, determines their location and the availability of a roaming partner, checks the account balance, and authorizes or rejects the request for service. The application server also identifies whether there are multiple possible roaming partners and whether preferred or optimal service can be obtained from a roaming partner via DOCMANAG E_LEGAL_676281.1 different IMSI, and related parameters on the dual-sided UICC card. If new parameters can be provisioned to provide a preferred service, the application server sends an SMS message back to the dual-sided UICC with the updated parameters, that are then imported into the dual-sided UICC and the mobile device reinitiated on the preferred network and/or with the preferred parameters.
[000431 This concludes the description of the presently preferred embodiments of the invention.
The foregoing description has been presented for the purpose of illustration and is not intended to be exhaustive or to limit the invention to the precise form disclosed.
