Abstract

A method and apparatus to set up a call between at least one standard analog terminal and a remote terminal, via a radio terminal or access a remote terminal or request a service in the network, via a radio terminal, while the radio terminal is engaged in a conversation with another remote terminal in the network. To access the remote terminal or request a service in the network, while the radio terminal is engaged in a conversation with another remote terminal in the network: clear the contents of the memory, wherein a first dialed digit is received from the standard analog terminal, the radio terminal instructs the termination of call set up processing, the first dialed digit is stored in the memory, the first dialed digit forms the contents of the memory, a number is then formed to represent the remote terminal from the contents of the memory, the radio terminal is then instructed to initiate call set up processing using the number, a subsequent dialed digit is received from the standard analog terminal, the radio terminal is instructed to terminate call set up processing, and the subsequently dialed digit is stored in the memory, wherein together with the contents of the memory, updated contents are formed, a new number representing the remote terminal is formed from the updated contents of the memory, the radio terminal is instructed to initiate call set up processing using the new number, and wherein the procedure is repeated.

g) storing the first dialed digit in the memory, wherein the first dialed digit forms the contents of the memory;

h) forming a number representing the remote terminal for the service requested from the contents of the memory; and

i) initiating flash access preparation using the number.

4. The method of claim 3, further comprising the steps of:

j) receiving a subsequently dialed digit from the standard analog terminal;

k) instructing the radio terminal to terminate flash access preparation;

l) storing the subsequently dialed digit in the memory, together with the contents of the memory, to form updated contents;

m) forming a new number representing the remote terminal or the requested service from the updated contents of the memory;

n) instructing the radio terminal to initiate flash access preparation using the new number; and

n) repeating the steps j-n.

5. The method of claim 4, wherein the steps j-n are repeated for each subsequently dialed digit as long as the subsequently dialed digit is received from the standard analog terminal before a flash request is sent to the network from the radio terminal.

6. An apparatus for setting up a call between at least one standard analog terminal and a remote terminal in a network via a radio terminal, the apparatus comprising:

a processor receiving a first dialed digit from the standard analog terminal and instructing the radio terminal to terminate call set up processing; and

a memory storing the first dialed digit,

wherein the memory is initially cleared, the first dialed digit forms the contents of the memory, and the processor forms a number representing the remote terminal from the contents of the memory and instructs the radio terminal to initiate call set up processing using the number, and

wherein if subsequently dialed digits are received from the standard analog terminal, the processor instructs the radio terminal to terminate call set up processing, the contents of the memory are updated to include the subsequently dialed digits, and the processor forms a new number representing the remote terminal from the updated contents of the memory and instructs the radio terminal to initiate call set up processing using the new number.

7. The apparatus of claim 6, wherein for each subsequently dialed digit, the processor instructs the radio terminal to terminate call set up processing, the contents of the memory are updated to include the subsequently dialed digit, and the processor forms a new number representing the remote terminal from the updated contents of the memory and instructs the radio terminal to initiate call set up processing using the new number, as long as the subsequently dialed digit is received from the standard analog terminal before the radio terminal sends a request for call set up to the network.

8. An apparatus for accessing a remote terminal or requesting a service in a network from at least one standard analog terminal via a radio terminal, while the radio terminal is engaged in a conversation with another remote terminal in the network, the apparatus comprised of the following:

a processor receiving a register recall indication from the standard analog terminal and instructing the radio terminal to terminate flash access preparation;

a memory that is cleared upon receipt of the register recall indication by the processor, wherein, after the memory is cleared, the processor instructs the radio terminal to initiate flash access preparation wherein upon receipt of a first dialed digit, the processor instructs the radio terminal to terminate flash access preparation, the first dialed digit is stored in memory and forms the contents of the memory and the processor forms a number representing the remote terminal or the requested service from the contents of the memory and instructs the radio terminal to initiate flash access preparation using the number.

9. The apparatus of claim 8, wherein, subsequently dialed digits are received from the standard analog terminal, the processor instructs the radio terminal to terminate flash access preparation, the contents of the memory are updated to include the subsequently dialed digits, and the processor forms a new number representing the remote terminal or the requested service from the updated contents and instructs the radio terminal to initiate flash access preparation using the new number.
