Abstract: Embodiments include communication devices and texting methods performed by communication devices. When the communication device detects that a text session has been initiated with a potential real time text (RTT) destination specified as a destination for text messages transmitted by the communication device, the communication device automatically transitions into an RTT transmission mode. While in the RTT transmission mode, text messages may be communicated to the destination using an RTT protocol. A response system may be configured to communicate with the communication device, while the communication device is in the RTT transmission mode.

Abstract: A method (200) and system (100) for sharing podcast information includes a wireless communication device (101) having a transceiver (102), and a processor (104) coupled to the transceiver. The processor can be programmed to play (202) a podcast having associated metadata on a wireless communication device and transfer (204) a hyperlink and the associated metadata to a remote device (103) while playing the podcast on the communication device. The processor can be further programmed to transfer the hyperlink and the associated metadata to the remote device while playing the podcast by using a push-to-transmit function (109) on the communication device. The remote device receives the link and associated metadata and decodes (206) the associated metadata. The associated metadata can include constructs having start times and end times for the podcast, bookmarks for portions of the podcast, digital rights management information, display description, podcast category, or relevant images.

Abstract: A communication construct used for sharing podcast information associated with a podcast can include a link sent to a remote device (103) while playing the podcast, appended metadata to the link, and a communication packet enabling a user to transfer the link and the appended metadata while the user is playing the podcast. The link can be a universal record locator (URL) to the podcast and the appended metadata can include constructs having start times or end times for the podcast, bookmarks for portions of the podcast, digital rights management information, display description, podcast category, or relevant images. The appended metadata can also include URLs for mobile blogging, a sender's weblog, a video blog, a social contact site, contact information from a sender, or a vCard record. The communication constructs enable podcatcher software in a user's computer or remote device to automatically download the podcast associated with the link.

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: A system (20) of targeted broadcasting in a cellular communication system during an event can include at least one mobile unit (25) having stored therein scheduling information relating to an event, a designated location for the event, and a designated group channel for monitoring such event. The mobile unit can further be programmed to monitor (67) for the event in a designated location and on a designated group channel during a predetermined time window and receive (71) a targeted message during the event on the designated group channel if a current location of the mobile unit matches the designated location stored. The mobile unit can be programmed to transmit at least one group call message response in response to receiving the group call message only when the mobile unit is in the designated location. The system can further include fixed network equipment (26) that transmits data related to the event.

Abstract: A system (200) includes a visiting wireless device (202) and a host wireless device (206) that communicate with each other. A shared user interface is commonly used by the two devices. During an ongoing interaction between a user of the visiting device (202) and a user of the host device (206), images of each user (106 and 108) are communicated to the other device and both devices display the images of both user. Through updated images communicated back and forth between the devices, the users “virtually” interact with the shared user interface. A permission level restricts the interactions available to the visiting device (202).

Abstract: A mobile communication device (106) comprising a transceiver (202), and a processor (203) coupled to the transceiver. The processor is programmed to enter (304) an emergency mode corresponding to an alteration type of an element of the mobile communication device, and process (306) messages according to the emergency mode.

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.

Abstract: The invention concerns a method (300) and system (100) for selectively controlling the operation of a power source (126). The method can include the steps of—in a first gaming unit (110)—providing (314) a gaming environment, monitoring (316) a user's performance in the gaming environment and selectively controlling (318) a power capacity of the power source in response to the user's performance in the gaming environment. The power capacity can be a perceived power capacity. The selectively controlling step can include increasing (320) or decreasing (320) the perceived power capacity of the power source.
