Abstract
An IMS (IP Multimedia Subsystem) network contains at least one of (A) a discovery function (2) for providing ISIM (IP Multimedia Subscriber Identity Module) discovery information to the mobile device (1) and (B) a provisioning function (2, 5, 6) for providing, in response to a request from a mobile device, an ISIM to the mobile device (1). Where the IMS network contains the discovery function, the discovery function is adapted to provide ISIM discovery information to the mobile device, and where the IMS network contains the provisioning function, the provisioning function is adapted to provide an ISIM to the mobile device (1).
Claims25
An IMS (IP Multimedia Subsystem) network, comprising:
- at least one application server configured to provision a mobile device over the IMS network and comprising a node of the IMS network, the at least one application server comprising:
- at least one processor;
- and
- at least one memory coupled to the at least one processor, the at least one memory comprising a non-transitory computer readable medium having computer readable program code embodied therein that is executed by the at least one processor to perform operations comprising:
- (1) a discovery function for providing ISIM (IP Multimedia Subscriber Identity Module) discovery information over the IMS network, the discovery function identifying a provisioning function to the mobile device by sending a Session Initiation Protocol (SIP) message comprising the ISIM discovery information from the IMS network to the mobile device,
- wherein the mobile device is registered with the IMS network using a provisioning ISIM;
- and
- (2) the provisioning function for providing an operational ISIM to the mobile device over the IMS network by sending a SIP message comprising the operational ISIM from the IMS network to the mobile device in response to a request transmitted from the mobile device to the at least one application server over the IMS network based on the provisioning function identified in the ISIM discovery information, wherein the IMS network temporarily uses the provisioning ISIM to identify the mobile device while performing the discovery function to provide the ISIM discovery information over the IMS network to the mobile device, and then uses the operational ISIM provided to the mobile device by the provisioning function to identify the mobile device without further use of the provisioning ISIM to identify the mobile device.

A method of provisioning a mobile device with an IMS (IP Multimedia Subsystem) subscription over an IMS network, the method comprising:
- (1) sending, from the IMS network, a Session Initiation Protocol (SIP) message comprising discovery information identifying an ISIM (IP Multimedia Subscriber Identity Module) provisioning function to the mobile device,
- wherein the mobile device is registered with the IMS network using a provisioning ISIM;
- and
- (2) in response to a SIP request received at the IMS network from the mobile device based on the provisioning function identified in the discovery information, sending, from the IMS network, a SIP message comprising an operational ISIM to the mobile device, wherein the IMS network temporarily uses the provisioning ISIM to identify the mobile device while performing a discovery function to send the discovery information identifying the ISIM provisioning function over the IMS network to the mobile device, and then uses the operational ISIM provided to the mobile device by the ISIM provisioning function to identify the mobile device without further use of the provisioning ISIM to identify the mobile device.
1 more element
A method of provisioning a mobile device over an IMS network with an IMS (IP Multimedia Subsystem) subscription, the method comprising:
- inputting discovery information received in a Session Initiation Protocol (SIP) message from the IMS network into the mobile device, the discovery information identifying an ISIM (IP Multimedia Subscriber Identity Module) provisioning function for the mobile device;
- sending a SIP request message comprising a provisioning request from the mobile device to the IMS network based on the ISIM provisioning function identified in the discovery information,
- wherein the mobile device is registered with the IMS network using a provisioning ISIM;
- and
- provisioning, at the mobile device, an operational ISIM that is received in a SIP response message from the IMS network in response to sending the SIP request message comprising the provisioning request from the mobile device to the ISIM provisioning function,
- using the provisioning ISIM to identify the mobile device while receiving the discovery information from the IMS network into the mobile device, and then using the operational ISIM provided to the mobile device by the provisioning to identify the mobile device without further use of the provisioning ISIM to identify the mobile device.

An IMS (IP Multimedia Subsystem) network element of an IMS network, the IMS network element comprising:
- at least one processor;
- and
- at least one memory coupled to the at least one processor, the at least one memory comprising a non-transitory computer readable medium having computer readable program code embodied therein that is executed by the at least one processor to perform operations comprising:
- (1) a discovery function for providing ISIM (IP Multimedia Subscriber Identity Module) discovery information over the IMS network, the discovery function identifying a provisioning function to a mobile device by sending a Session Initiation Protocol (SIP) message comprising the ISIM discovery information from the IMS network to the mobile device, wherein the mobile device is registered with the IMS network using a provisioning ISIM;
- and
- (2) the provisioning function for providing an operational ISIM to the mobile device over the IMS network by sending a SIP message comprising the ISIM from the IMS network to the mobile device in response to a request transmitted from the mobile device to the IMS network element over the IMS network based on the provisioning function identified in the ISIM discovery information,
- wherein the IMS network element comprises a node of the IMS network, and
- wherein the IMS network temporarily uses the provisioning ISIM to identify the mobile device while performing the discovery function to provide the ISIM discovery information over the IMS network to the mobile device, and then uses the operational ISIM provided to the mobile device by the provisioning function to identify the mobile device without further use of the provisioning ISIM to identify the mobile device.
