A method and apparatus for effectuating unidirectional and bidirectional communication directly between a mobile telephone and another device without the use of a mobile telephone system to carry the communication. A communication path and a communication format are assigned to the mobile telephone and the device either through a fixed preassignment or dynamically by the mobile telephone system. The communication path constitutes a portion of a radio spectrum assigned to the mobile telephone system, and the communication format includes a modulation type and a communication protocol. The communication path is removed from a set of communication paths allocated for use by the mobile telephone system and the communication path and communication format are stored in separate memories located in the mobile telephone and the device. Controllers located within the mobile telephone and the device initiate communication directly between the mobile telephone and the other device on the assigned communication path using the assigned communication format.

Short distance communication and remote control capability for mobile telephones

A method of placing a calling account card telephone call on a call by call basis using one of a plurality of carrier networks is disclosed. The method includes the steps of storing a plurality of data sets in accordance with requirements for use of the carrier networks, detecting the initiation of each telephone call by recognizing a first predetermined sequence input by the user and detecting the initiation of each calling card call by recognizing a second predetermined sequence input by the user, the second predetermined sequence being different than the first predetermined sequence, retrieving one of the stored data sets responsive to the detected second predetermined sequence, and automatically initiating a telephone call in accordance with the retrieved stored data sets responsive to inputting of the second predetermined sequence. An apparatus for automatic execution of a telephone calling card call on a call by call basis using one of a plurality of carrier networks is also provided.
