ABSTRACT:
A method and apparatus set up a call between at least one standard analog terminal and a remote terminal in a network, via a radio terminal and a radio base station. The contents of a memory are initially cleared. If a first dialed digit is received from the standard analog terminal, verification of the radio terminal status is terminated, if it is in progress, and the first dialed digit is stored in the memory, forming the contents of the memory. Verification of the radio terminal status includes, for example, sampling and evaluation of radio signal strengths, determining the service restrictions of the radio terminal, and determining whether the radio terminal is authorized to make a call from the cell in which it is located, using an operator's SIM card. Verification of the radio terminal status is initiated, and the contents of the memory are sent to a buffer. If a subsequently dialed digit is received from the standard analog terminal, verification of the radio terminal status is terminated. The subsequently dialed digit is stored in the memory, together with the contents of the memory, to form updated contents. Verification of the radio terminal status is initiated, and the updated contents are sent to the buffer. When verification of the radio terminal status is completed, and the radio terminal is determined to be ready for call set up, call set up processing is initiated or a request for call set up is sent from the radio terminal to the radio base station. These steps are repeated for each subsequently dialed digit, as long as the subsequently dialed digit is received from the standard analog terminal before call setup processing is initiated or before a request for call setup is sent from the radio terminal to the radio base station.
