摘要： 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 “Active Set”. 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 “Neighbor Set”. 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).

摘要： A mobile user terminal 402 accesses a packet data network 450 through one or more of several network access points 404-412. One or more control points 432-440 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 418-420 which determines which foreign agents need to be accessed on behalf of each user terminal. There are several foreign agents 422-430, which forward packets received from a user terminal's home agent to the control point currently controlling communications with the user terminal.

摘要： A method and apparatus for rapidly assigning traffic channels to a plurality of mobile stations in a wide area high-speed packet data cellular communication system. Mobile stations transmit access probes on randomly selected access channels to selected base stations to initiate traffic channel assignments. The access probe comprises a pilot preamble, a traffic channel request, and a pilot/data request channel (DRC). The pilot preamble allows the selected base station to easily detect the access probe transmission. The traffic channel request includes data that identifies the mobile station. Immediately after transmitting the traffic channel request, the mobile station begins communicating with the base station on both the forward and reverse communication links. The selected base station immediately supervises the mobile station's transmission power. The mobile station selects from a group of available power control sub-channels. The mobile station selects an available channel and an associated power control sub-channel from the list.

Mobile stations transmit access probes on randomly selected access channels to selected base stations to initiate traffic channel assignments. The access probe comprises a pilot preamble, a traffic channel request, and a pilot/data request channel (DRC). The pilot preamble allows the selected base station to easily detect the access probe transmission. The traffic channel request includes data that identifies the mobile station. Immediately after transmitting the traffic channel request, the mobile station begins communicating with the base station on both the forward and reverse communication links. The selected base station immediately supervises the mobile station's transmission power. The mobile station selects from a group of available power control sub-channels. The mobile station selects an available channel and an associated power control sub-channel from the list. In another alternative embodiment, the base station, and not the mobile station, initiates the traffic channel assignment process. A base station controller instructs all base stations within the mobile station's paging radius to transmit a page message on the forward link. The mobile station continuously monitors the forward link and responds to pages addressed to its associated MSI. When a page to the mobile station is detected, the mobile station initiates a traffic channel request. In addition, the mobile station immediately monitors the power control sub-channel that it identified in the detected page message.

摘要： Reverse link busy bits are independently generated by each base station and indicate whether a base station has reached a reverse link capacity limit. A remote station combines multipath components of the reverse link busy bits in its Active Set and in response transmits a reverse link signal only when all of the reverse link busy bits indicate that the base stations in the Active Set have reverse link capacity. In an embodiment, the remote station weights the reverse link busy signals in accordance with the signal strength of the transmitting base station and determines whether to transmit based on the weighted sum of the busy signals. In an embodiment, the remote station weights the reverse link busy signals in accordance with the signal strength of the transmitting base station and determines a maximum reverse link data rate based on the weighted sum of the busy signals.
