EUICC card memorizing short numbers by subscriber profile to notify a subscription management server
View Patent ↗The disclosure relates to the notification of an SM-SR subscription management server by an eUICC card or an eSE element. The card includes, in local memory, at least one short number (or “short code”), and more generally an address identifier, unique to a mobile-phone operator, wherein the number is associated with an operator subscriber profile within the secure card. The card is configured to retrieve, from the local memory, a short code associated with a subscriber profile in use to send, using the retrieved short code, a card status notification to the SM-SR server. In the absence of a short code, the card uses a unique international telephone number as the recipient of the notification.
1. A secure element for connection to a mobile telephone network ( 10 ), comprising, in local memory, two short numbers denoting the same remote subscription management server in a mobile network infrastructure for two respective mobile network operators, each short number being specific to one of the mobile network operators and being associated with a different operator subscriber profile ( 21 , 22 ) in the secure element, and wherein said secure element is configured to recover from the local memory the short number associated with a subscriber profile being used and, to send an SMS message to said recovered short number, said SMS message including a secure element status notification, thus allowing transmission of said secure element status notification to the remote subscription management server via a short message service SMS-C server specific to the mobile network operator associated with the recovered short number.
2. The secure element as claimed in claim 1 , comprising, in local memory, a correspondence table ( 23 ) enabling association of each short number with each subscriber profile.
3. The secure element as claimed in claim 2 , in which the correspondence table ( 23 ) memorizes each short number in association with an index, which index is memorized in a corresponding subscriber profile.
4. The secure element as claimed in claim 2 , in which the correspondence table ( 23 ) memorizes each short number in association with the subscriber profile identifier.
5. The secure element as claimed in claim 1 , in which each short number is memorized in the associated subscriber profile.
6. The secure element as claimed in claim 1 , further comprising a unique international telephone number ( 24 ) of the remote subscription management server, said secure element being configured to recover said unique international telephone number from the local memory when no short number is associated with a subscriber profile being used and, using said recovered unique international telephone number, to send a secure element status notification to the remote subscription management server.
7. The secure element as claimed in claim 1 , configured:
to receive from the remote subscription management server a command to update an address of the remote server in the local memory of the secure element, the update command including a unique international telephone number ( 24 ) of the secure routing unit and/or at least one short number, associated with a subscriber profile ( 21 , 22 ) and designating the remote server, and
to update, in the local memory of the secure element and in response to the update command, the unique international telephone number of the remote server and/or the at least one short number in association with a subscriber profile as indicated in the update command, so as to notify the subscription management server using the updated numbers.
8. The secure element as claimed in claim 7 , in which the update command is similar to the “UpdateSMSRAdressingParameters” command defined in section 4.1.1.10 of the GSMA 12FAST.15 standard, version 1.0 as of 17 Dec. 2013, augmented by at least one double-field associating a short number with a subscriber profile identifier.
9. The secure element as claimed in claim 1 , of secure card type.
10. A mobile telephone network infrastructure system comprising a subscription management server and comprising a plurality of subscriber terminals each equipped with a secure connection element as claimed in claim 1 for sending notifications to the subscription management server using an short number, the short number being specific to a mobile network operator.
11. The system as claimed in claim 10 , in which the remote subscription management server is configured to send a command to update an address of the remote server, the update command including a unique international telephone number of the remote server and/or at least one short number associated with a subscriber profile and designating the remote server, so as to update, in the memory of the secure elements, the unique international telephone number of the remote server and/or the at least one short number in association with a subscription profile as indicated in the update command.
12. The system as claimed in claim 10 , further comprising two short message service SMS-C servers specific to two mobile network operators respectively, each short message service server comprising, in local memory, a table ( 11 , 12 ) of correspondences between a short number, that is specific to said mobile network operator and an IP address of the same remote subscription management server.
13. A method of communication in a mobile telephone network ( 10 ) executed by a secure element for connection to the mobile telephone network, the secure element comprising, in local memory, two short numbers denoting the same remote subscription management server in a mobile network infrastructure for two respective mobile network operators, each short number being specific to one of the mobile network operators and associated with a different operator subscriber profile ( 21 , 22 ), the method comprising, on reception of an event triggering notification, the following steps:
recovering ( 350 , 352 ), from the local memory the short number associated with a subscriber profile being used, and
sending ( 358 ) an SMS message to said recovered short number, said SMS message including a secure element status notification, thus allowing transmission of said secure element status notification to the remote subscription management server via a short message service SMS-C server specific to the mobile network operator associated with the recovered short number.
14. The method as claimed in claim 13 , in which the secure element
receives ( 306 ) from the subscription management remote server a command to update an address of the remote server, the update command including an unique international telephone number ( 24 ) of the remote server and/or at least one a short number, associated with a subscriber profile ( 21 , 22 ) and designating the remote server, and
updates ( 308 , 310 , 312 ), in its local memory and in response to the update command, the unique international telephone number of the remote server and/or the at least one short number in association with a subscriber profile as indicated in the update command, so as to notify the subscription management server using the updated numbers.
