Method of access provision

A method in an Internet Protocol (IP) Multimedia Subsystem (IMS) mobile communication network, comprising:

• receiving from a mobile terminal, a network information element, wherein
• the network information element comprises a home network identifying element that identifies a home network of the mobile terminal, and
• the mobile terminal does not have any dedicated IMS mobile communication identities and no IMS subscriptions in the home network;
• receiving home subscription data related to a home network subscription of the mobile terminal;
• executing an IMS subscription generating procedure for generating an IMS subscription using the home subscription data, wherein the IMS subscription comprises a user profile upon recognizing the network information element;
• and
• providing the mobile terminal access to the IMS mobile communication network based on the IMS subscription.

A method in a mobile terminal, comprising:

• generating a network information element, wherein
• the network information element comprises a home network identifying element that identifies the home network of the mobile terminal, and
• the mobile terminal does not have any dedicated Internet Protocol (IP) Multimedia Subsystem (IMS) communication identities and no IMS subscriptions in the home network;
• and
• sending the network information element to an IMS mobile communication network, wherein the mobile terminal accesses the IMS mobile communication network via an IMS subscription generated using home subscription data retrieved by the IMS mobile communication network from the home network.

A mobile terminal, comprising:

• a transceiver;
• a controller further comprising:
• a microprocessor, and
• a computer-readable storage medium, coupled to the microprocessor, and including computer-readable instructions, when executed by the microprocessor, are configured to:
• generate a network information element, wherein
• the network information element comprises a home network identifying element that identifies the home network of the mobile terminal, and
• the mobile terminal does not have any dedicated Internet Protocol (IP) Multimedia Subsystem (IMS) communication identities and no IMS subscriptions in the home network;
• and
• send, via the transceiver, the network information element to an IMS mobile communication network, wherein the mobile terminal accesses the IMS mobile communication network via an IMS subscription generated using home subscription data retrieved by the IMS mobile communication network from the home network.
