  • Publication number: 20080214201
    Abstract: Systems and techniques for grouping channels, such as pilots, are described. In one aspect, a method includes receiving transmissions of two or more pilot signals at an access terminal of a wireless communications network that includes an access node, based on characteristics of the transmissions of the two or more pilot signals from the access node to the access terminal, determining whether the two or more pilot signals are suitable for grouping and indicating of the suitability of the two or more pilot signals for grouping by sending a pilot information report for the pilot group to the access node.

  • Patent number: 7411927
    Abstract: According to one embodiment of the present invention, a method of optimizing point-to-point sessions is disclosed. A registration request is received from a mobile node. The mobile node communicates with a current packet controller function serviced by a packet data serving node. Whether the registration request comprises a previous access network identifier is determined. The previous access network identifier identifies a previous packet controller function. Whether the mobile node is serviced by a mobile Internet Protocol is determined. Next, whether the mobile node communicated with a previous packet controller function serviced by the packet data serving node is determined. The method concludes by deciding whether to negotiate a point-to-point session for the mobile node in response to on the determinations.

  • Publication number: 20080101291
    Abstract: Interconnection and integration of a WWAN and a WLAN to provide continuous packet data services to mobile users where each mobile access terminal is configured to support both air links with the WWAN and WLAN. The WWAN may be a CDMA2000 system and the WLAN may be an IEEE 802.11 system.

  • Patent number: 7301922
    Abstract: A system, a method, and software for communicating packet data are disclosed. A call is communicated from a mobile device through a first base station controller and a first packet data serving node. The call is transferred from the first base station controller to a second base station controller in communication with a second packet data serving node. The call is then communicated through a tunnel established between the first packet data serving node and the second packet data serving node.

  • Publication number: 20030208602
    Abstract: A method for pushing data in an internet protocol (IP) network environment is provided that includes assigning a network identifier to an end user of a mobile station. A relationship is determined between the network identifier and an IP address element, the relationship being stored in a database. A query is received for the network identifier of the end user and, in response to the query, the IP address element is provided such that a querying entity may push data to the mobile station.

  • Patent number: 5949773
    Abstract: The method of transferring a CDMA data signal (107) associated with a mobile station (103) which operates between a source system (202) and a target system (204). The method includes establishing a frame relay switched virtual circuit (FR SVC) transport function capability in the source system (202) and, consequently generating a plurality of parameters. The method also includes determining that the mobile station (103) requires a transfer of the CDMA data signal (107) which results in forwarding a message from the source system to the target system to transfer the CDMA data signal (107), the message including the plurality of parameters. Based on the plurality of parameters, converting the CDMA data signal (107) into a FR SCV format by the target system (204), forming a frame relay data signal, which is routed via the target system (204) to an inter working function element (IWF)(214) of the source system (202).
