Packet Processing Relay Agent To Provide Link Layer Forwarding In One-Way Cable/Wireless/Satellite Modems
A method and apparatus for allowing a personal computer to receive data from a computer network such as the Internet via a broadcast channel of a cable or satellite television network, while transmitting data upstream to the computer network via a telephone line. A packet processing relay agent (PPRA) forwards data at the data link layer between a one-way network adapter, such as a cable modem that receives Internet data via a cable network, and a two-way return path adapter, such as a telephone modem that communicates with Internet servers and other users via a telephone network. The system provides compatibility with TCP/IP routing/addressing conventions by forwarding upstream IP packets with a cable modem source address over the telephone modem. The PPRA can enhance functionality by incorporating higher layer functions at the data link layer.
System And Method For Enabling Multicast In A Cdma Network
An improved wireless communications system for efficiently delivering multicast transmissions within a CDMA wireless communications network. To minimize use of network resources, a multicast group Walsh code is dynamically assigned for transmissions to group members for the duration of the session. Reverse link multicast long code covers are assigned by a base station controller and transmitted to the mobile station on a forward channel as derived from the multicast IP address. A multicast reflection function is provided at the base station controller or the IP gateway to transmit multicast messages received from mobile stations to other group members in their coverage area. The assigned group Walsh codes and long codes are used to spread all multicast transmissions on the CDMA forward and reverse channels, respectively.
A method for an uninitialized client to obtain credentials from a server which are then used to provide authenticated exchange for network configuration parameter assignment. The obtained credentials can be applied to an authentication option when a dynamic host configuration protocol (DHCP) is being used for address assignment.

Abstract:
A method () of establishing an alternate HRPD signaling link between an HRPD access network and an access terminal over a non-HRPD access is disclosed. It includes: providing () a signal forwarding function (SFF) () between an access terminal (AT) () and a high rate packet data (HRPD) access network (AN) (); establishing () a data tunnel () between the access terminal () and the SFF (); exchanging () HRPD signaling messages and HRPD data via the data tunnel (); identifying () the HRPD access network () and the access terminal () over non-HRPD access by the SFF (), by reading a header with certain identifiers and mapping the header to an address of the access terminal or network; and forwarding () the HRPD signaling messages and the HRPD data that arrive at the SFF () from the access terminal () and the HRPD access network () to the HRPD access network () and the access terminal (), respectively. The method () performs an initiation and session establishment procedure, minimizes the time, disruption and packet loss during handoff to a HRPD access network and enables seamless mobility.

Abstract:
A communication system reduces set up time for an inter-technology handoff of a multi-mode mobile station (MS) from a source network associated with a first radio frequency (RF) technology to a target network associated with a second RF technology by pre-establishing, prior to a determination to handoff the MS, a registration state of the MS and an authentication of the MS in association with the target network and second RF technology. In order to pre-establish the registration state and authentication, the MS exchanges messaging of the second RF technology with the second network via the first network and first RF technology. To facilitate the exchange, the MS includes shims in a second protocol stack associated with the second technology, which shims intercept second protocol stack signaling and redirect the intercepted signaling to a first protocol stack of the MS, associated with the first technology, for tunneling to the source network.

Method And System For Transitioning Media Output Among Two Or More Devices
In at least some embodiments, the present invention relates to methods and systems for enabling media content to be utilized or output by way of media presentation devices. In one such embodiment, a method includes receiving at a first cloud a first signal from a first media presentation device indicative of a request or command that a content signal transmission be paused, and sending a second signal including bookmark information from the first cloud to a second media presentation device. The method further includes receiving a third signal from the second media presentation device, the third signal being indicative of a further request or command that the transmission of the media content signal be resumed, and resuming the transmission. In additional embodiments, the present invention relates to methods of operating a media presentation device so as to perform a resumed displaying of video media content.

Abstract:
An Internet protocol (IP) based location system that employs a global positioning system (GPS) component in connection with a position determining entity (PDE) component to determine location of target mobile station(s) via the Internet. As such the system provides an internet protocol based scheme (e.g., UDP) to initiate a location determination session within a CDMA network. The system can provide a location determining service even when the mobile station(s) are not within a home network (e.g., roaming situations). The system can also employ HTTP over TCP/IP so as to facilitate communications between the mobile station(s) and a mobile positioning center (MPC) (e.g., authentication and/or security protocols/schemes). Furthermore, the system can identify a PDE of a plurality of available PDEs that is most suitable for a given state of the mobile station and/or state of the user and/or particular location based application being employed by the mobile station.
