Abstract: A system (20) and method (50) of establishing a rapid push-to-send data exchange in a multi-wireless network environment can include a first wireless network (24 and 26) having a fast network channel to exchange an Internet Protocol (IP) address or other data, a second wireless network (23 and 27) operatively coupled to the first wireless network having a high bandwidth data channel to exchange data using the IP address in a wireless peer to peer data transfer, and a communication protocol. The first wireless network can be an iDEN network and the second wireless network can be a CDMA network. The communication protocol can relinquish (66) communication using the first wireless network once a dedicated data channel on the second wireless network is established. The communication protocol can also simultaneously transfer (56) voice traffic on the first network when the first network is exchanging the IP address.

Abstract: A method (400) and system (300) of indicating receipt of a call from a caller on a shared home network can include extracting (402) information from the calling party or the calling party's network indicating an originating network, sending (406) information of the originating network to a called party, and indicating (410) if the originating network belongs to the called party's shared home network. The indication can be an icon (11) or other visual indication on a mobile subscriber unit's user interface (13), or by sharing v-card or other user identification information between the calling party and the called party or by sending or providing an audible indication to the called party. The indication can be done before enabling the ability of the called party to answer a call. The step of extracting can optionally include extracting (404) information from billing information to indicate the originating network.

Abstract: A mobile station (110) that includes a first network adapter (210) configured to communicate over a first communications network (120) and a second network adapter (220) configured to communicate over a second communications network (130). The mobile station also includes a multimodal processing module (250) that generates a busy notification in response to receiving a call via the second network adapter while the mobile station is engaged in a first call via the first network adapter. The busy notification can be automatically generated by the multimodal processing module in response to the second call being received, or generated in response to receiving a user input entered in response to the second call has been received.

Abstract: A system (20) of establishing a rapid PTT call setup in a multi-wireless network environment, can include a first wireless network (24 and 26) such as an iDEN network optimized for rapid push-to-talk call setups in typically less than one second and a second wireless network (23 and 27) such as a CDMA wireless network operatively coupled to the first wireless network. The system can further include a communication protocol among an originating mobile subscriber unit (22), a target mobile subscriber unit (28), the first wireless network, and the second wireless network, where the first wireless network and the second wireless network receive a request for a PTT session and the PTT session is set up on the second wireless network using the first wireless network. The system can further include a PTT server (25) operatively coupled to the first wireless network and the second wireless network.

Abstract: An apparatus (213) and corresponding methods (FIG. 7) to facilitate maintaining crypto synchronization while processing communication signals in a communication unit includes a vocoder (215) configured to convert input audio band signals to vocoder output frames; a crypto processor (217) configured to encrypt the vocoder output frames to provide encrypted output frames; and a synchronizer (219) configured to substitute in a predetermined manner synchronization information corresponding to an encryption state of the crypto processor for a portion of the encrypted data in a portion of the encrypted output frames to provide resultant output synchronization frames suitable for synchronizing a decryption process at a target communication unit.

Abstract: An apparatus (102a) for causing an orchestrated rendering of pre-selected data content using a plurality of communications devices (102b-e) is provided. The apparatus includes a signal transmitting circuit (202) for transmitting a performance signal to at least one of the plurality of communications devices, the performance signal including a synchronization instruction. The apparatus additionally includes a synchronization module (208) communicatively connected to the transmitting circuit for generating the synchronization instruction. The synchronization instruction is based upon the pre-selected data content and causes the at least one communications device to perform a designated portion of the data content at a designated time during a rendering of the pre-selected data content.

Abstract: An encryption capable communication device (10) can include a transceiver (38 and 44) and a processor (12) coupled to the transceiver. The processor can be programmed to receive notification of a secure call alert indicative of a desire for secure communications between an alerting device and the encryption capable communication device serving as a recipient device and further cause the recipient device to switch (64) to a secure mode in response to receipt of the notification. The processor can be further programmed to initiate a key exchange (67) between the alerting device and the recipient device if needed and automatically respond (70) to the secure call alert by the recipient device in the secure mode when a user of the recipient device selectively responds to the secure call alert. The processor can also establish a symmetric traffic key during the key exchange using Automatic Public Key exchange techniques.
