Method and system for access and use of multiple ISIM or ISIM credentials
A method at a mobile entity for enabling use of multiple Internet Protocol (IP) Multimedia Services (IMS), the method including reading data from a plurality of IMS Subscriber Identity Modules (ISIMs) associated with the mobile entity; storing the data at the mobile entity; and binding a function at the mobile entity to one of the plurality of ISIMs.
1. A method at a mobile entity for enabling use of multiple Internet Protocol (IP) Multimedia Services (IMS), the method comprising:
reading data from a plurality of IMS Subscriber Identity Modules (ISIMs) associated with the mobile entity;
storing the data at the mobile entity;
determining that an indication in the data for one of the plurality of ISIMs includes an indication for a function;
binding the function at the mobile entity to the one of the plurality of ISIMs, the binding comprising storing an application identifier in association with the one of the plurality of ISIMs; and
binding a second function at the mobile entity to a second one of the plurality of ISIMs;
wherein the indication is stored in an Application Identifier Application at the ISIM;
wherein the plurality of ISIMs are associated with a Universal Integrated Circuit Card (UICC) on the mobile entity;
wherein when a selected function is invoked, an ISIM bound to the selected function is used.
2. The method of claim 1 , wherein the binding is based on provisioning of the data at each of the plurality of ISIMs to a plurality of functions.
3. The method of claim 1 , wherein the indication is an explicit field in an IMS Subscriber Identity Module (ISIM).
4. The method of claim 1 , wherein the indication is an IMS Communication Service Identifier.
5. The method of claim 1 , wherein the indication is an IMS Application Reference Identifier.
6. The method of claim 1 , wherein the indication is an Access Point Name.
7. A mobile entity for enabling use of multiple Internet Protocol (IP) Multimedia Services (IMS), the mobile entity comprising:
a processor; and
a communications subsystem,
wherein the mobile entity is configured to:
read data from a plurality of IMS Subscriber Identity Modules (ISIMs) associated with the mobile entity;
store the data at the mobile entity;
determine that an indication in the data for one of the plurality of ISIMs includes an indication for a function;
bind the function at the mobile entity to the one of the plurality of ISIMs, the binding comprising storing an application identifier in association with the one of the plurality of ISIMs; and
bind a second function at the mobile entity to a second one of the plurality of ISIMs;
wherein the indication is stored in an Application Identifier Application at the ISIM;
wherein the plurality of ISIMs are associated with a Universal Integrated Circuit Card (UICC) on the mobile entity;
wherein when a selected function is invoked, an ISIM bound to the selected function is used.
8. The mobile entity of claim 7 , wherein the mobile entity is configured to bind based on provisioning of the data at each of the plurality of ISIMs to a plurality of functions.
9. The mobile entity of claim 7 , wherein the indication is an explicit field in an IMS Subscriber Identity Module (ISIM).
10. The mobile entity of claim 7 , wherein the indication is an IMS Communication Service Identifier.
11. The mobile entity of claim 7 , wherein the indication is an IMS Application Reference Identifier.
12. The mobile entity of claim 7 , wherein the indication is an Access Point Name.
13. A non-transitory computer readable medium for storing instruction code for enabling use of multiple Internet Protocol (IP) Multimedia Services (IMS), which, when executed by a processor of a mobile entity cause the mobile entity to:
read data from a plurality of IMS Subscriber Identity Modules (ISIMs) associated with the mobile entity;
store the data at the mobile entity;
determine that an indication in the data for one of the plurality of ISIMs includes an indication for a function;
bind the function at the mobile entity to the one of the plurality of ISIMs, the binding comprising storing an application identifier in association with the one of the plurality of ISIMs; and
bind a second function at the mobile entity to a second one of the plurality of ISIMs;
wherein the indication is stored in an Application Identifier Application at the ISIM;
wherein the plurality of ISIMs are associated with a Universal Integrated Circuit Card (UICC) on the mobile entity; and
wherein when a selected function is invoked, an ISIM bound to the selected function is used.
