Patent number: 8588777Abstract: 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”. 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).Type: GrantFiled: January 3, 2007Date of Patent: November 19, 2013Assignee: QUALCOMM IncorporatedInventors: Matthew Stuart Grob, Roberto Padovani, Paul E.

Patent number: 8274948Abstract: 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.Type: GrantFiled: May 11, 2010Date of Patent: September 25, 2012Assignee: QUALCOMM IncorporatedInventors: Paul E.

Patent number: 7961592Abstract: A variable rate transmission system transmits a variable rate data packet including an accompanying rate indication signal indicative of the transmission rate of the variable data packet. The data packet can be spread using a long pseudonoise (PN) code, the mask of which can be selected in accordance with the transmission rate of the variable rate data packet. A preamble, providing the transmission rate, can be punctured into an outgoing pilot signal. The rate indication signal can be encoded in accordance with a set of orthogonal functions that are part of the indication of the transmission rate of the data packet.Type: GrantFiled: November 15, 2007Date of Patent: June 14, 2011Assignee: QUALCOMM IncorporatedInventors: Peter J.

Patent number: 7630719Abstract: 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.Type: GrantFiled: April 14, 2004Date of Patent: December 8, 2009Assignee: QUALCOMM IncorporatedInventors: Paul E.

Patent number: 7599329Abstract: In a system including a resource which is shared among a number of users, it is difficult to distribute the available capacity of the resources fairly among the users and still maximize resource utilization. Additionally, it is desirable to allow at least some of the control over usage rates to remain with the users, while at the same time avoiding situations where the resource is overloaded. A system and method are disclosed wherein usage rates are selected from among a set of available rates according to a set of persistence vectors.Type: GrantFiled: June 1, 2007Date of Patent: October 6, 2009Assignee: QUALCOMM IncorporatedInventors: Gadi Karmi, Matthew Stuart Grob, Paul E.

Patent number: 7483699Abstract: A system and method for providing a simple, but effective technique for communicating overhead messages in a wireless communication system providing access to a decentralized network, while achieving bandwidth savings as well as minimizing power consumption. In one embodiment, a wireless base station which is connected to a decentralized network transmits a sequence of signatures for overhead messages to a mobile unit. The mobile unit wakes up receives the signatures and compares them to signatures stored at the mobile unit. If the signatures received by the mobile unit are different from the signatures stored at the mobile unit, the mobile unit stays awake to receive the overhead messages to be transmitted by the wireless base station. If the signatures received by the mobile unit are the same as the signatures stored at the mobile unit, the mobile unit may go back to sleep.Type: GrantFiled: September 22, 1998Date of Patent: January 27, 2009Assignee: QUALCOMM IncorporatedInventors: Gadi Karmi, Matthew S.

Patent number: 7158537Abstract: The layers and protocols of an air interface layering architecture are designed to be modular and can be modified and upgraded to support new features, perform complex tasks, and implement additional functionality. Prior to commencement of data communication between a first entity (e.g., an access terminal) and a second entity (e.g., a radio network), a set of layers and/or protocols is selected for negotiation. For each selected layer and protocol (i.e., each attribute), a list of attribute values considered acceptable to the first entity is determined. The selected attributes and their associated attribute values are sent from the first entity and, in response, a list of processed attributes and their associated lists of processed attribute values are received. Each list of processed attribute values includes attribute values considered acceptable to the second entity.Type: GrantFiled: December 30, 2002Date of Patent: January 2, 2007Assignee: Qualcomm, Inc.Inventors: Paul E.
