Abstract

A method for the communicating of a subscriber identity module, implemented or implementable in an end device, in which at least one profile is adapted for the utilization of the mobile end device in a mobile communication network, vis-à-vis a server, in which method a message from the subscriber identity module is sent to the server. Before the sending of the message, a step of the establishing of a technology is carried out in the subscriber identity module in which there is established, which technology the profile corresponds to, and the sending is carried out compliant with the technology. The communicating can involve the notifying of a profile change effected in the subscriber identity module.

First claim

1 .- 14 . (canceled)

15 . A method for communicating of an subscriber identity module,
implemented or implementable in an end device, in which at least one profile is adapted for the utilization of the mobile end device in a mobile communication network, vis-à-vis a server, in which method a message from the subscriber identity module is sent to the server, wherein before the sending of the message, a step of the establishing of a technology is carried out in the subscriber identity module in which there is established, which technology the profile corresponds to, and the sending is carried out compliant with the technology.

16 . The method according to claim 15 , wherein as a server a subscription management server including a SubMan Secure Router is provided.

17 . The method according to claim 15 , wherein 3GPP or/and 3GPP2 is provided as a technology.

18 . The method according to claim 15 , wherein as a message a status message is provided by which a status change of the profile, including activation or deactivation, is indicated.

19 . The method according to claim 15 , wherein the profile is initially in an active status and wherein as a message a status message is provided, through which a profile change from the profile to a further profile implemented in the subscriber identity module is indicated.

20 . The method according to claim 19 , wherein
initially the profile in the subscriber identity module is designed as active profile, which has an active status; in addition to the profile, at least one further profile is implemented, which is designed as inactive profile, which has an inactive status, wherein respectively only one profile at once is in an active status; in the method, a profile change is carried out by deactivating the initially active profile so that it is put into an inactive status, and activating one of the further profiles so that the further profile is put into an active status; and after the profile change, the status message is sent to the server.

21 . The method according to claim 15 , wherein on the occasion of the step of establishing the technology, on basis of a result of the establishing, one or several communication channels are specified which are subsequently employed for the communicating of the subscriber identity module vis-à-vis the server, including several communication channels ordered according to an instruction for use, including prioritization or selection, wherein respectively one communication channel is associated with one technology.

22 . The method according to claim 21 , wherein the communication channels comprise one or several the following: a data connection, a Short Message Service connection, a speech message connection, an SS string connection, a USSD string connection.

23 . The method according to claim 21 , wherein in an individual profile at least two partial areas are provided which correspond to the different technologies, and wherein for at least two different technologies respectively one different communication channel is specified.

24 . The method according to claim 15 , wherein the message from the subscriber identity module to the server is embedded in a 3-way handshake protocol, wherein the message is sent as a first message, wherein according to the 3-way handshake protocol after the sending of the first message the second message is to be sent from the server to the subscriber identity module, and after the sending of the second message the third message is to be sent by the subscriber identity module to the server.

25 . The method according to claim 24 , wherein messages notifying of a profile change are communicated embedded in a 3-way handshake protocol and other messages are communicated embedded in a 2-way handshake protocol.

26 . The method according to claim 15 , wherein the step of the establishing of a technology is carried out by establishing a parameter which has a parameter value specific to a technology.

27 . The method according to claim 26 , wherein the parameter is established by reading out a parameter field, including by processing a command in the subscriber identity module, on the occasion of its processing the parameter is employed, and wherein on the occasion of the processing the parameter field is read out.

28 . The method according to claim 15 , wherein a logical channel is associated with the technology according to ISO/IEC 7816-4, including the base channel channel 0, or where applicable, a separate logical channel is associated with each technology according to ISO/IEC 7816-4.
