ABSTRACT:
A first chip card is provided for use in a telecommunications terminal which is connected in a telecommunications network. The first chip card exchanges signaling and data directly with the telecommunications network at the telecommunications terminal. The first chip card includes a signaling and dam processor for processing the signaling and data exchanged with the telecommunications network and a signaling and data memory for storing signaling and data received from the telecommunications network and for storing signaling and data processed by the signaling and data processor. A telecommunications protocol processor of the first chip card processes multiple telecommunications protocols including both telecommunications protocols for radios and telecommunications protocols for wired communications. When the first chip card is inserted in the telecommunications terminal, the functionality of the telecommunications terminal is solely determined by the first chip card. A plurality of chip cards may be inserted in the telecommunications terminal, and the first chip card is further capable of checking whether at least one further chip card is inserted in the telecommunications terminal. The first chip card is also capable of exchanging signaling and data with another chip card in the telecommunications terminal.
