Method and apparatus for supporting enhanced international dialing in cellular systems
First Claim
1. A method of dialing a call using international number in a CDMA serving network, comprising:
- entering a dialed number comprising a digit string that corresponds to an international telephone number, wherein the dialed number begins with a + indicator, followed by a country code, an area code and a customer number, automatically translating the digit string into a new number based on a numbering plan of the area in which the call is being placed; and
sending the new number to the CDMA serving network to set up the call.

Abstract
A method and apparatus are provided that support enhanced international dialing in cellular systems using handset based code dialing. According to one aspect, the handset analyzes the dialed digits before sending the dialed number to the network. If the dialed digits begin with the country code of the area from which the call is placed, the country code will be removed and a national access code will be added in front of the digit strings. For international calls the dialed number may begin with a + indicator, followed by a country coded, an area code, and a customer number. The digit string is automatically translated into a new number based on the numbering plan of the area in which a call is being placed. The new number can then be sent to the network to set up the call.

7. A method of placing a call in a serving wireless network that serves users in an area of operation, comprising:
-
entering a called number which comprises a country code, an area code and a customer number;
determining whether the called number further comprises an optional indicator and further determining whether the country code corresponds to a country code of the serving network before sending the called number to the serving network;
if the called number includes the optional indicator and the country code does not correspond to the country code of the serving network, translating the optional indicator to an international access code for the serving network to generate a modified called number; and
inserting the international access code of the serving network into the modified called number to generate a new called number. - View Dependent Claims (8, 9, 10, 11, 12, 13)
