Method and system for multiparty calling using a dual mode phone with private call
First Claim
1. A method for multi-party communication for push-to-talk on a dual mode communication device, comprising the steps of:
- establishing an interconnect call on a first network between the dual mode communication device and a second communication device;
receiving a request for a private call on a second network from a third communication device;
mixing and routing audio from the private call and the interconnect call at the dual mode communication device when a multiparty call mode is selectively chosen; and
wherein the dual mode communication device has a first modem operating on the first network and a second modem operating on the second network and the method further comprises mixing a microphone input at the dual mode communication device with audio generated from the interconnect call on the first network and routing a mixed signal to the second modem.

Abstract
A method (100) and system (20) for multiparty communication using at least one dual mode communication device includes a dual mode radio (11) having at least a first modem (12) for operation on a first network and a second modem (13) for operation on a second network and a processor (55) coupled to the radio. The dual mode radio can be programmed to establish (102) an interconnect call on a first network between the dual mode radio and a second communication device, receive (104) a request for a private call on a second network from a third communication device, and mix and route (106) audio from the private call and the interconnect call at the dual mode radio when a multiparty call mode is selectively chosen. The dual mode radio can be a first modem operating on a CDMA network and a second modem operating on an iDEN network.

10. A system for multiparty communication using at least one dual mode communication device, comprising:
-
a dual mode radio having at least a first modem for operation on a first network and a second modem for operation on a second network; and a processor coupled to the dual mode radio, wherein the dual mode radio is programmed to; establish an interconnect call on a first network between the dual mode radio and a second communication device; receive a request for a private call on a second network from a third communication device; mix and route audio from the private call and the interconnect call at the dual mode radio when a multiparty call mode is selectively chosen; and wherein the dual mode radio is further programmed to mix incoming voice received over the air from the first modem with incoming voice received over the air from the second modem to form a mixed received signal and further route the mixed received signal to a speaker at the dual mode radio. - View Dependent Claims (11, 12, 13, 14, 15)

16. A dual mode radio used for three way calling with private mode, comprising:
-
a first transceiver for operation on a first network; a second transceiver for operation on a second network; and a processor coupled to the first transceiver and the second transceiver, wherein the dual mode radio is programmed to; establish an interconnect call on a first network between the dual mode radio and a second communication device; receive a request for a private call on a second network from a third communication device; mix and route audio from the private call and the interconnect call at the dual mode radio when a multiparty call mode is selectively chosen; and
wherein the dual mode radio has a first modem operating on the first network and a second modem operating on the second network;
mixing a microphone input at the dual mode radio with audio generated from the interconnect call on the first network and routing a mixed signal to the second modem. - View Dependent Claims (17)
