Appl. No.:

09/158665

International Classification:

H04Q 720

US Classification:

455442, 455437, 455450, 370332

Abstract:

A communication system that allows a soft handoff to be completed, even when the communications link between the active base station and the mobile station deteriorates before the mobile station has received the handoff direction message. The mobile station maintains a list of base stations that the mobile station is in communication with, referred to as an âActive Setâ. In addition, the mobile station maintains another list of base stations that are proximate to the base stations in the active set. This list is referred to as the âNeighbor Setâ. A memory within the mobile station includes information that would allow the mobile station to demodulate information transmitted from those base stations on the neighbor set. In accordance with the disclosed method and apparatus, the mobile station places a base station in the active set upon including the base station in a pilot strength measurement message (PSMM). The mobile station monitors transmissions from all of the base stations on the active set to receive a handoff direction message (HDM).

International Classification:

G06F 1516

US Classification:

709228, 709249, 709250

Abstract:

A system provides wireless data service. The system includes a wireless modem configured to be coupled to a terminal equipment unit over a wireline broadcast medium. A network unit is coupled to the wireless modem over a wireless link connection. A network remote server is coupled to the network unit. The network remote server provides IP address information in response to terminal equipment unit address request messages for terminal equipment units coupled to the network unit. In addition, a local server is coupled to the wireless modem. The local server provides IP address information in response to terminal equipment unit address request messages from terminal equipment units coupled to the wireline broadcast medium.

International Classification:

H04B 700

US Classification:

455517, 455509, 370342, 370510

Abstract:

In one disclosed embodiment, communication between a mobile unit and a base station is performed at a data transfer rate selected from, for example, a finite set of HDR data transfer rates. Meanwhile, the mobile unit continually computes a moving average of the data transfer rates. The mobile unit also ascertains a supportable data rate for receiving data. The supportable data rate can be selected from a finite set of HDR data transfer rates. In order to maintain the moving average of the data transfer rate within a specified range, the mobile unit transmits maximum data rate requests or null data requests to the base station. The maximum data rates requested by the mobile unit are equal to or lower than the supportable data rate.

Abstract:

A system and method for performing base station initiated call setup is provided. A base station initiated call setup may be utilized to establish a test call, to deliver a packet data services call to a subscriber unit, or to reactivate a dormant packet call. The base station transmits a BS Service Request message to the mobile switching center, requesting initiation of the call. The mobile switching center will authorize the call if the call to be set up is directed to a subscriber unit located within the service area of the base station and if the service option to be used is authorized for the particular subscriber unit. The mobile switching center will allow or disallow the call depending on the state of the subscriber unit. The mobile switching center transmits a BS Service Response message to the base station, conveying the result of processing the BS Service Request message. If the base station initiated call setup is authorized and allowed, the call will generally proceed in the same manner as a subscriber terminated call.

International Classification:

H04B 7/00

US Classification:

370338

Abstract:

A mobile user terminal accesses a packet data network through one or more of several network access points. One or more control points determines which network access point or points the user terminal is to access. Control may be retained in the current control point, or transferred to another control point, whenever it is convenient. There are preferably several routers, each having an associated home agent which determines which foreign agents need to be accessed on behalf of each user terminal. There are several foreign agents , which forward packets received from a user terminal's home agent to the control point currently controlling communications with the user terminal.
