Abstract: The disclosed embodiments provide apparatus and methods for establishing a group communications session with selected ones of a plurality of communications devices that define a call group. The apparatus includes a dispatch module operable to receive event information and communication device information associated with each of the plurality of communications devices. The dispatch module is further operable to define the members of the call group based on a predetermined relationship between their respective device information and the event information. Additional embodiments include apparatus and methods for dispatching event information to such an ad hoc call group.

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 Code Division Multiple Access (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.

Abstract: Opportunistic transmission of voting and/or opinion data can occur from a user's mobile device to a server. The user can be presented a form to complete, where the form is designed to facilitate gathering of opinion information. Opinion data gathered from the form can be opportunistically transmitted to a server, where transmission commonly occurs when a supplemental transmission takes place. The transmission can be received by a server and a user that provided the opinion and/or voting information can be rewarded, such as through a monetary payment. The opinion and/or voting information can be extracted and retained in storage.

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.

Abstract: A 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.
