Abstract: In systems and methods of managing push-to-talk registration of a wireless device, a network attachment request is received from a wireless device in a first geographic service area, a service plan identifier associated with the wireless device is received, and based on the service plan identifier a domain name node network address is provided to the wireless device. A network address of a push-to-talk application node associated with a second geographic service area is determined based on the domain name node network address. The wireless device is then registered in the first geographic service area with the push-to-talk application node associated with the second geographic service area.

Abstract: Systems and methods of operating a communication system are provided. A network node of the first network can receive a request from a wireless device associated with the first network to establish a data communication session over a second network through an access node of the second network. A status of the access node of the second network can be determined based on an access node identifier. A location of the wireless device can be determined at the network node of the first network. A network condition of the first network can be determined based on the location of the wireless device. The request to establish the data communication session over the second network can be granted when the network conditions of the first network are less than a threshold and the access node of the second network does not have an approved roaming status.

Abstract: Integrating multiple transport modes into a single communication stream on a computing device such as a mobile computing device. One or more recipients and one or more transport modes available for communication with the one or more recipients are provided to a user. An application program executing on the computing device receives a first message from the user to send to one or more selected recipients. The computing device transmits the received first message to the selected recipients via a first transport mode. Thereafter, the computing device receives a second message from one of the recipients via a second transport mode. The received second message is displayed to the user in the same communication stream by the application program. As an example, the user uses the application program to communicate with the recipients using text messaging, electronic mail message, and other transport modes.

Abstract: Disclosed is a method and system for use of a trusted server such as an over-the-air provisioning server to facilitate mobile location determination. If a mobile location server (MLS) sends a location-determination message to a mobile station and does not receive a response back from the mobile station, there is a chance that the mobile station is not provisioned with a correct address of the MLS and that the mobile station therefore did not respond. To help jump start the location-determination process, the MLS may respond to that situation by instead causing a trusted server such as an over-the-air-service-provisioning (OTASP) server to send a location-determination message to the mobile station, triggering a response from the mobile station.

Abstract: Method for providing a versatile notepad for social networking and interactions with a plurality of users. An input content is received from a user. The received input content is analyzed based on at least the following expression types: expression indicative of time, expression indicative of a location, expression indicative of a statement, expression indicative of an individual, an expression indicative of a list, and a combination of expressions indicative the time, the location, the statement, the list, and the individual. The analyzed information is dynamically converted to a communication object as a function of the expression types. The communication object is rendered to the user.
