International Classification:

H04J 15/00

US Classification:

370464, 37914218, 380270

Abstract:

A method and apparatus for allowing a transparent service option transition between at least two wireless communication devices (WCDs). A first communication between a first WCD and a second WCD is established using a first service option. At some point during the first communication, a transition to a second service option, such as an asynchronous data service option, is initiated. At least one of the WCDs provides an identification code to the other WCD using a signaling protocol over the first service option. The first communication is then terminated. A second communication using the second service option is then initiated by one of the WCDs, resulting in a seamless transition to the second service option.

International Classification:

H04K 1/10

H04L 9/00

US Classification:

380 33, 380257, 380270, 713153

Abstract:

The disclosed systems and methods include a native portable communications device having an application module that modifies communications between the portable device and a non-native communications device connected to a non-native communications network. The application module transforms communications between a native standard to a non-native standard to allow interoperability between the native portable communications device and the non-native communications device within the non-native communications network. Further, the application module may modify communications in other manners, such as to apply a security function to the communication. Additionally, the systems and methods may include a communications accessory for switching communications between the application module of the native device, the non-native device, and the non-native network. Thus, the native portable communications device and the associated methods of operation with the application module provide a mobile system that enables modified communications over various communications networks.

09/905510

Inventors:

Dan Vassilovski - Del Mar CA, US

Maria Marshall - Oceanside CA, US

Assignee:

QUALCOMM, Incorporated - San Diego CA

International Classification:

H04B 7/216

US Classification:

370342, 370349, 370352

Abstract:

A wireless communication device without IP capability nonetheless communicates with an infrastructure that uses IP. To effect call set-up, an over-the-air (OTA) origination message from the wireless communication device is received by an infrastructure component, which in turn generates IP-based messages having headers that are extended to include information related to the OTA protocol. The IP-based messages with extended headers are then used internally to the infrastructure to effect call set-up.

US Classification:

380273, 380260, 380277, 713150

Abstract:

The disclosed embodiments provide for methods and apparatus for encrypting media using a current media encryption key (MEK), requesting a new MEK, and receiving the new MEK. The method further provides for transitioning from the current MEK to the new MEK and continuing to encrypt the media using the new MEK. In another embodiment, the method provides for decrypting media during an ongoing media communication session, the method provides for receiving encrypted media, and decrypting the encrypted media using a current MEK. The method further provides for requesting a new MEK before the current MEK expires based on its associated expiration time, receiving the new MEK, and continuing to decrypt the encrypted media based on a received MEK indication flag (MIF) that indicates whether the encrypted media is encrypted using the current MEK or the new MEK.

Abstract:

system and method for transmitting CDMA call set-up parameters including authentication parameters through an IP-based infrastructure to an authenticating entity. A base station encapsulates, in SIP messages, CDMA data from wireless communication devices, with the headers of the messages indicating the presence of the CDMA-specific data in the message body. The SIP messages are routed through the infrastructure to an IS41 gateway, which strips the CDMA-specific data from the SIP messages and sends the necessary data to the authenticating entity for setting up a CDMA call.

Abstract:

A wireless telephone without IP capability nonetheless communicates with an infrastructure that uses IP. Virtual IP endpoints such as base stations (BTS) not only communicate with the infrastructure using IP and with the telephone using over-the-air protocol such as CDMA, but one of the endpoints also selects the best frame over a call received by multiple endpoints, alleviating the need for a base station controller (BSC) in the infrastructure. A handoff assist entity causes frame selection to be transferred to a second BTS in accordance with a handoff algorithm.
