Abstract

A method and apparatus for controlling multi-party conference calls includes circuitry which is operable according to a new conference call protocol. The protocol and accompanying apparatus and method allow a conference call controlling party to selectively have private conversations with one of the subject parties in the conference call. Additionally, the controlling conference call party may selectively drop conference call participants. A mobile station includes a store for storing the conference call participant “subject party setup number” in relation to the subject party number and/or name. The mobile station also allows the conference call controller to scroll up and down a list of conference call participants. This allows the controller to be certain of a conference call participant'"'"'s “call set-up number” when using a command for a private call or a command to drop a conference call participant.

Claims

1. A mobile station, comprising:

a display;

a store for storing conference call information;

circuitry for determining and controlling the storing and displaying a called party set-up number in relation to one of the called party name or number during a conference call with respect to a relative order in which the called party was added to the conference call whereby the calling party is able to select a conference call action by entering a called party set-up number and a key that represents the desired action;

circuitry for generating a display image on the mobile station, the display image including the called party set-up number in relation to a called party ID comprising one of a called party name or number; and

circuitry for generating control commands in relation to the call set-up number displayed on a display of the mobile station.

2. The mobile station of claim 1 including means to allow a calling party to scroll up and down a list of called party numbers in relation to the called party set-up number.

3. The mobile station of claim 1 including means to allow a calling party to scroll up and down a list of one of called party names or numbers, according to what is shown, in relation to the determined called party set-up number.

4. A mobile station, comprising:

a display;

a memory;

a processor formed to control wireless communications for a conference call and for controlling calling information displayed on the display, which processor stores, in the memory, a calling party ID consisting of one of a called party name or a called party number and, in association with the calling party ID, a called party'"'"'s set up number;

circuitry for generating a display image on the mobile station, the display image including the called party set-up number in relation to a called party ID comprising one of a called party name or number; and

circuitry for generating control commands in relation to the called party'"'"'s set-up number displayed on a display of the mobile station wherein the called party set-up number is determined with respect to a relative order in which the called party was added to the conference call.

5. The mobile station of claim 4 wherein the processor examines the contents of the memory to determine if, in relation to and for a given called party set up number, the called party has a corresponding called party name.

6. The mobile station of claim 5 wherein the processor displays the called party name in association with the called party set up number whenever the called party name is known.

7. The mobile station of claim 6 wherein the called party name comprises an entered nickname.

8. The mobile station of claim 4 formed to enable a controlling party to scroll up and down a list of called party Ids and their corresponding set up numbers in the conference call to determine what key sequences are necessary for performing a desired conference call effect.

9. A method in a mobile station for controlling a conference call, comprising:

receiving a called party phone number for a called party;

determining a subject party set up number wherein the set-up number is determined with respect to a relative order in which the called party was added to the conference call;

initiating wireless communication signals to establish a conference call with the called party;

storing the called party phone number in relation to the called party set up number; and

generating control commands in relation to the call set-up number displayed on a display of the mobile station.

10. The method of claim 9 further comprising the step of storing the subject party name, whenever the subject party name is known, in relation to the set up number.

11. The method of claim 10 further including the step of displaying the set up number and either the subject party name or phone number on a mobile station display to facilitate a controlling party'"'"'s ability to determine what key strokes are necessary to achieve a conference call effect.

12. The method of claim 9 further comprising the step of transmitting conference call control commands to a base station, which conference control commands include a subject party ID.

13. The method of claim 12 further including the step of, upon entry of a single digit set up number and a key representing a conference call control command, determining the subject party ID that is to be transmitted to the base station.

14. The method of claim 9 further including the steps of:

if a call has not yet been established with the called party, establishing the call once a mobile station “

SEND”

key is depressed; and

if a call has been established with the called party, and if the conference call has at least three participants, performing a selected conference call action for a specified conference call participant whenever the specified conference call participant set-up number is entered and the “

SEND”

key is depressed.

15. The method of claim 14 further including the step of dropping the specified conference call participant if the set-up number, one of the “

*”

or “

#”

keys are depressed and the “

SEND”

key is depressed.

16. The method of claim 14 of re-establishing a conference call with all participants after a private conference whenever the “

SEND”

key is depressed during a private conference.

17. A mobile station, comprising:

a display;

a memory;

a processor formed to control wireless communications for a conference call and for controlling calling information displayed on the display, which processor stores, in the memory, a calling party ID consisting of one of a called party name or a called party number and, in association with the calling party ID, a called party'"'"'s set up number;

circuitry for generating a display image on the mobile station, the display image including the called party set-up number in relation to a called party ID comprising one of a called party name or number; and

circuitry defining logic for controlling a conference call, which logic includes;

logic for determining the called party set-up number with respect to a relative order in which the called party was added to the conference call;

logic for re-establishing a conference call with all participants after a private conference whenever the “

SEND”

key is depressed during a private conference; and

logic for dropping the specified conference call participant as identified by a conference call participant set-up number if the set-up number, one of the “

*”

or “

#”
