Abstract

A mobile device includes first identification circuitry and second identification circuitry. The first identification circuitry is associated with a first network and the second identification circuitry is associated with a second network. The mobile device simultaneously registers itself with the first and second networks using the first and second identification circuitry, respectively. The first and second identification circuitry may each comprise subscriber identity modules. The mobile devices handle outgoing and incoming calls based on user preferences. The user may override the preferences for selected calls.

Claims

1. A method of establishing communication with a mobile device, which method comprises:

establishing a first identity for said mobile device;

establishing a second identity for said mobile device;

registering said mobile device with a first network using said first identity;

designating one of said identities as a preferred identity, wherein said preferred identity is designated according to user preferences, and wherein said user preferences include at least one exception defining when the identity that is not the preferred identity is utilized to place calls from the mobile device rather than the preferred identity, wherein said at least one exception includes one of a preset time exception and a preset date exception; and

simultaneously registering said mobile device with a second network using said second identity, said second identity being different from said first identity, wherein said mobile device is able to remain simultaneously registered with first and second networks in order to receive calls at substantially a same time for both the first and the second identities, and at any time for either the first and the second identities.

2. The method as claimed in claim 1, wherein said first network is the same as said second network.

3. The method as claimed in claim 1, further comprising:

receiving a command to place a call from said mobile device; and

placing said call from said mobile device using said preferred identity.

4. The method as claimed in claim 3, further comprising:

prior to placing said call from said mobile device using said preferred identity;

prompting a user to override said preferred identity; and

in response to said user overriding said preferred identity, placing said call from said mobile device using the identity not designated as said preferred identity.

5. The method as claimed in claim 1, further comprising:

receiving a call from a calling party, said call being for an intended one of said identities; and

completing said call to said intended one of said identities.

6. The method as claimed in claim 5, further comprising:

designating one of said identities as a preferred identity;

if said intended one of said identities is not said preferred identity, instructing said calling party to call said preferred identity.

7. The method as claimed in claim 1, wherein:

the first identity is established using a first subscriber identity module; and

the second identity is established using a second subscriber identity module.

8. A mobile device, which comprises:

a controller coupled to first identification circuitry and second identification circuitry and which performs the functions of;

receiving first identification circuitry, said first identification circuitry being associated with a first network;

receiving second identification circuitry, said second identification circuitry being associated with a second network;

establishing a first identity for said mobile device associated with the first identification circuitry;

establishing a second identity for said mobile device associated with the second identification circuitry;

designating one of said identification circuitry as a preferred identification circuitry, wherein said preferred identification circuitry is designated according to user preferences, and wherein said user preferences include at least one exception defining when the identity that is not the preferred identity is utilized to place calls from the mobile device rather than the preferred identity, wherein said at least one exception includes one of a preset time exception and a preset date exception;

registering said mobile device with said first network using said first identification circuitry with said first identity; and

simultaneously registering said mobile device with said second network using said second identification circuitry with said second identity, wherein said mobile device is able to remain simultaneously registered with first and second networks in order to receive calls at substantially a same time for both the first identification circuitry and the second identification circuitry and at any time for either identification circuitry.

9. The mobile device as claimed in claim 8, wherein:

the first identification circuitry comprises a first subscriber identity module; and

the second identification circuitry comprises a second subscriber identity module.

10. The mobile device as claimed in claim 8, wherein the controller further performs the functions of:

receiving a command to place a call; and

placing said call using said preferred identification circuitry.

11. The mobile device as claimed in claim 8, wherein said first network is different from said second network.

12. The mobile device as claimed in claim 8, wherein the controller further provides maintaining user preferences.

13. The mobile device as claimed in claim 12, wherein said user preferences include preferred identification circuitry.

14. The mobile device as claimed in claim 13, wherein said user preferences include exceptions to said preferred identification circuitry which exceptions define when the identification circuitry that is not the preferred identification circuitry is utilized to place calls from the mobile device rather than the preferred identification circuitry.
