Method of handling automatic call origination and system determination on multi-network mobile devices

A communications device, comprising:

• means for registering with a preferred network;
• means for receiving an origination request for a call, the origination request comprising a service parameter and a dialing string;
• means for determining a marking condition for the dialing string to indicate a supportability and form of the call on each of a plurality of communications networks, comprising:
• means for generating a first marking to indicate that the call is allowed on each of the plurality of communications networks upon determining that the dialing string indicates an emergency number,
• means for accessing and comparing against user-defined permission information to determine if the call is allowed on each of the plurality of communications networks upon determining that the dialing string excludes the emergency number,
• means for generating a second marking to prohibit the call upon determining that the call is not allowed on any of the plurality of communications networks, and
• means for generating a third marking to indicate the dialing string or a converted dialing string based on the user-defined permission information or a service request code of the call upon determining that the call is allowed on one of the plurality of communications networks;
• means for identifying compatible communications networks from the plurality of communications networks to support the call as a function of the first, second and third marking conditions for the dialing string;
• means for determining whether the call is allowed or not allowed on the registered network;
• means for originating the call on the registered network when it is determined that the call is allowed on the registered network;
• and
• means for registering with another of the identified compatible networks and means for originating the call when it is determined that the call is not allowed on the registered network.

A communications device, comprising:

• at least one processor configured to:
• register with a preferred network;
• receive an origination request for a call, the origination request comprising a service parameter and a dialing string;
• determine a marking condition for the dialing string to indicate a supportability and form of the call on each of a plurality of communications networks, comprising:
• generating a first marking to indicate that the call is allowed on each of the plurality of communications networks upon determining that the dialing string indicates an emergency number,
• accessing and comparing against user-defined permission information to determine if the call is allowed on each of the plurality of communications networks upon determining that the dialing string excludes the emergency number,
• generating a second marking to prohibit the call upon determining that the call is not allowed on any of the plurality of communications networks, and
• generating a third marking to indicate the dialing string or a converted dialing string based on the user-defined permission information or a service request code of the call upon determining that the call is allowed on one of the plurality of communications networks;
• identify compatible communications networks from the plurality of communications networks to support the call as a function of the first, second and third marking conditions for the dialing string;
• determine whether the call is allowed or not allowed on the registered network;
• originate the call on the registered network when it is determined that the call is allowed on the registered network;
• and
• register with another of the identified compatible networks and originate the call when it is determined that the call is not allowed on the registered network.

A computer program product, comprising:

• a non-transitory computer-readable medium embodying codes executable to:
• register with a preferred network;
• receive an origination request for a call, the origination request comprising a service parameter and a dialing string;
• determine a marking condition for the dialing string to indicate a supportability and form of the call on each of a plurality of communications networks, comprising:
• generating a first marking to indicate that the call is allowed on each of the plurality of communications networks upon determining that the dialing string indicates an emergency number,
• accessing and comparing against user-defined permission information to determine if the call is allowed on each of the plurality of communications networks upon determining that the dialing string excludes the emergency number,
• generating a second marking to prohibit the call upon determining that the call is not allowed on any of the plurality of communications networks, and
• generating a third marking to indicate the dialing string or a converted dialing string based on the user-defined permission information or a service request code of the call upon determining that the call is allowed on one of the plurality of communications networks;
• identify compatible communications networks from the plurality of communications networks to support the call as a function of the first, second and third marking conditions for the dialing string;
• determine whether the call is allowed or not allowed on the registered network;
• originate the call on the registered network when it is determined that the call is allowed on the registered network;
• and
• register with another of the identified compatible networks and originate the call when it is determined that the call is not allowed on the registered network.
