  • Method of providing messages to a mobile unit on a forward link
    Patent number: 8331941
    Abstract: The present invention provides a method of wireless communication using a mobile unit and first and second base stations. The method includes receiving, from the second base station, a notification of a switch of the first base station to the second base station. The method also includes providing at least one message to the second base station in response to receiving the notification.

  • Method of constructing a QuickConfig message in a 1xEvolution Data Only (1xEV-DO) communication network and method of reducing call and handoff failure rates in the 1xEV-DO network without introducing additional call setup latencies
    Patent number: 8260335
    Abstract: In a method of constructing a QuickConfig message in a 1x Evolution (1XEV) data only (EV-DO) communication network for broadcast by a base station of the network to a plurality of users served thereby, a Forward Traffic Valid (FTValid) bit in a field of the QuickConfig message is set to a default value of a logic high state for all users. No delay occurs for a call setup between a given user and the base station even if the user requests the call setup after the QuickConfig message has been constructed by the base station.

  • Method of processing nested message layers
    Patent number: 7032027
    Abstract: A method of processing nested message layers which allows for encoding all the message layers into one formatted message buffer without incurring a copy at each message layer. A generalized approach for representing the context of each message layer and linking them to facilitate the encoding and decoding of message layers.
