    Abstract: A network function is configured to maintain a copy of a session state fo r an access terminal. The network function is further configured to query a session master to determine whether the session state has changed. The sessi on master is configured to generate a response to the query that enables the network function to update the copy of the session state if the session sta te has changed. The access terminal may be configured to change the session state at a first network function and send a message to a second network fun ction to indicate that the session state has been changed.

    Abstract: Methods and apparatus for communicating between an access terminal (AT) and a device serving the AT by way of an Access Point (AP) are described. In accordance with one feature serving devices may be assigned specific addresses which are interpreted based on the source of the communication, e.g., MAC packet, in which the address is used. Such addresses may be interpreted as being of a different type than other addresses which can be interpreted and/or used without taking into account the identity of the sender. In some embodiments Session Controllers and/or Internet Attachment Points (IAPs) are identified with such addresses. The address value is the same for one or more ATs but is interpreted at an AP receiving such the IAP address based on information corresponding to the AT which sent the packet including the IAP or Session Controller address.

    Abstract: A method for controlling transmission power of a remote station (122) in a soft handoff condition is provided. The method comprises receiving at the remote station (122) a power control command transmitted by each of the plurality of base stations (102, 104, 106), and increasing transmission energy of the remote station (122) only when each of the power control commands transmitted by the base stations in an Active Set of the remote station (122) requests an increase in the remote station transmission energy.

    Abstract: Metodos y sistemas para estimar y cancelar la interferencia piloto en un sistema de comunicacion inalambrica (por ejemplo CDMA); en un metodo, una senal recibida compuesta de un numero de casos de senal, cada uno incluyendo un piloto, es inicialmente procesada para proveer muestras de datos; cada interferencia piloto del caso de senal puede ser estimada mediante el desensanchamiento. de las muestras de datos con una secuencia de ensanchamiento para el caso de senal, la canalizacion de los datos desensanchados para proveer simbolos piloto, la filtracion de los simbolos piloto para estimar la respuesta de canal del caso de senal, y la multiplicacion de la respuesta de canal estimada con la secuencia de ensanchamiento; los estimados de interferencia piloto a causa de una pluralidad de multiples trayectorias en interferencia se acumulan para derivar la interferencia piloto total, la cual es sustraida de las muestras de datos para proveer muestras de datos de piloto cancelado; estas muestras de datos son procesadas para derivar datos desmodulados para cada una de por lo menos un caso de senal (deseado) en la senal recibida.

    Abstract: A system and method is taught for controlling the power level of transmissions within a communication system having a base station, a mobile station, a communication channel, and a pilot channel. The mobile station determines a signal strength value according to a communication signal received by way of the communication channel. A pilot channel signal is determined according to a pilot signal transmitted by way of the pilot channel. The signal to noise ratio of the communication signal is determined according to the determined signal strength value and the pilot channel signal. The power level of a transmission is controlled according to the signal to noise ratio. The noise level in a communication channel within the communication system is estimated. The pilot channel signal includes pilot energy and pilot noise components. The pilot energy component is removed to provide a remaining pilot signal. Communication system operations are controlled according to the remaining pilot signal. The power levels of transmissions are controlled by determining the signal to noise ratio of a signal within the communication channel and determining a difference signal. The difference signal is formed by determining the difference between determined and desired signal to noise ratios. The difference signal is transmitted between the base station and the mobile station. The pilot channel has at least one frame and the power control signal is inserted into the frame. Thus, information representing the strength of the communication signal is transmitted to the base by way of the pilot channel within the frame. The pilot channel can have two information frames for transmitting the power control signal a plurality of times.

    Abstract: Assignment of a session information IP address for use as a mobile station identifier facilitates a distributed architecture for processing IP communications in coordination with a wireless communication system. The session information IP address identifies a storage location of session information for a given AT. The AT effectively carries a pointer to the session information, wherein an access point is able to access the session information directly. This avoids the need to store mapping information for each AT and associated location of session information. Additionally, use of an IP address identifying the session holder as a mobile station identifier avoid delays incurred by such mapping. The session information IP address may be compressed to use a locally unique value. The compressed version conserves bit space, and reduces processing complexity on relocation to a next access point.
