Definitions

  • the invention relates generally to features in a mobile phone unit.
  • the invention relates to providing a system and method for effecting international calls in a roaming mode.
  • a mobile phone is the most common device that people around the world are carrying today. It is a very useful and convenient device for the traveling community. While traveling, the users of the mobile phones keep- in-touch with others and can do their normal business from anywhere in the world. A roaming facility in the mobile phones enables a user to make calls internationally from any place in the world.
  • IDD International Defined Devices
  • These codes can be in the form of 00, 001 , 002, 019, 091 , etc. Even within the same country there can be multiple codes, say in Singapore it is 001 , 002, 00 ⁇ ] 018 and 019 with different features being provided from same or different operators, but with significant cost differences and advantages. There exist a variety of choices to a user in terms of features and cost involved.
  • SMS as the SMS code is different generally and only "+" can be used for sending SMS.
  • a dialing method for effecting international call utilizes a conversion table for storing system codes of a plurality of network companies worldwide.
  • the mobile phone stores international access codes and a phone book for storing a plurality of telephone numbers having international access codes respectively of different called parties in the database.
  • the cellular phone is able to determine current location area while calling in international roaming and find the correct international access code from conversion table in accordance with system code received from an approximate network company for replacing international access code in telephone number searched from phone book.
  • US Patent No. 6,259,914 is issued to BellSouth Intellectual Property Corporation is titled as METHOD AND APPARATUS FOR IMPLEMENTING INTERNATIONAL WIRELESS ROAMING.
  • the invention discloses a method and apparatus for implementing international wireless roaming allows an international "roamer" to enter a visited system in a foreign country and originate calls.
  • the roamer's mobile station Upon entering the visited region, the roamer's mobile station initiates a registration request containing the mobile station's mobile identification number to the mobile switching center in the visited region.
  • the mobile switching center initiates a message to an appropriate home location register.
  • the home location register compares the mobile station's mobile identification number to a set of stored values.
  • the home location register will return an appropriately formatted North American Numbering Plan mobile directory number to the mobile switching center.
  • the mobile switching center uses the mobile directory number in signaling call related information, specifically in populating parameters such as the Calling Party Number. Recognizing a NANP-formatted number, the public switch telephone network will process the call as normal.
  • the invention reveals a system and method using canonical telephone numbers that allows automatic calling with any location in the world independent of the caller's location.
  • the caller canonical telephone number and a plurality of caller prefixes are stored within the system.
  • a telephone directory stores a plurality of callee canonical telephone numbers for locations throughout the world.
  • the caller manually enters a callee telephone number or selects a callee telephone number from the telephone directory.
  • the system determines if the callee telephone number is a canonical telephone number.
  • the system expands non-canonical telephone numbers to canonical form using known telephone numbering rules for various countries.
  • the system uses the callee canonical telephone number and the caller canonical telephone number to determine which digits of the callee canonical telephone number must be placed on the telephone line to complete the call. The system then adds the appropriate prefix for international, long distance, or local telephone calls to generate a final callee telephone number.
  • necessary calling prefixes are determined for placing a call from the MCU to the number to be called via the base station having the 'received SID code. Any necessary calling prefixes are appended to the number to be called, and a communication link is established between the MCU and the number to be called, via the base station having the SID code.
  • the MCU may utilize a database of dialing prefixes required to dial the number to be called from base stations having SID codes, and determining the necessary calling prefixes by searching the database for the received SID code by searching the database for either or both of the received SID code or a range of SID codes including the received SID code.
  • the invention concerns a method of converting stored canonical and non- canonical dialing information into dialing information which can be used to establish a connection, the initialization call number portion for an international telephone call and further number portions being present for the subscriber line for which the dialing information is emitted.
  • the emitted stored canonical and non-canonical dialing information is compared with the call number portions of the subscriber line.
  • first characters of the stored canonical and non-canonical dialing information match one or a plurality of first call number portions of the subscriber line, the matching call number portions reduce the dialing information. If necessary, an initializing call number portion required in addition to the remaining dialing information is added.
  • the prior art also involves sending a particular signal or code to mobile unit that may need programming and/or upgrading to existing base station. This may involve a massive programming effort and may involve disruption of services during upgrading. To practically upgrade all base stations is near to impossible;
