Patent number: 8787578Abstract: Method and apparatus for encrypting transmission traffic at separate protocol layers L1, L2, and L3 so that separate encryption elements can be assigned to separate types of transmission traffic, which allows the implementation of different levels of encryption according to service requirements. Encryption elements use variable value inputs, called crypto-syncs, along with semi-permanent encryption keys to protect from replay attacks from rogue mobile stations. Since crypto-sync values vary, a method for synchronizing crypto-syncs at the mobile station and base station is also presented.Type: GrantFiled: November 7, 2005Date of Patent: July 22, 2014Assignee: QUALCOMM IncorporatedInventors: Ramin Rezaiifar, Roy F. Quick, Jr., Paul Williamson, Jun Wang, Edward G. Tiedemann, Jr.

Patent number: 8285331Abstract: 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.Type: GrantFiled: June 26, 2006Date of Patent: October 9, 2012Assignee: QUALCOMM IncorporatedInventors: Rajeev Krishnamurthi, Roy F.

Patent number: 7319872Abstract: A system and method for providing mobile switching center (MSC) initiated service negotiation in a wireless communication system. If a new call arrives for a subscriber unit while the subscriber unit is already on the traffic channel, a change in the service configuration may allow the subscriber unit to receive the new call while preserving the old call. MSC initiated service negotiation may be used to establish the change in service configuration. The MSC transmits a Change Service Command message to the base station in whose coverage area the subscriber unit is located. The Change Service Command proposes a new service configuration to accommodate both the old and the new call. The base station, subscriber unit, and MSC may interchange further messages to modify the proposed service configuration if necessary. Messages are exchanged until the base station, subscriber unit, and MSC reach an agreement regarding the new service configuration. The present invention also provides support for soft handoff.Type: GrantFiled: December 21, 2000Date of Patent: January 15, 2008Assignee: QUALCOMM IncorporatedInventors: Rajeev Krishnamurthi, Bibhu P.

Patent number: 6870823Abstract: The invention is a method and apparatus for providing an Alert With Information Message signal between a mobile switching center and a base station in a cellular communication system. The invention recognizes that current provisions of the IS-634 standard lack support for certain required functionality on the interface between a mobile switching center and a base station, or the A-Interface. An Alert With Information Message signal is introduced on the A-Interface to support the required functionality. Introduction of the Alert With Information Message provides support for reliable call processing on the A-Interface for the call waiting procedure, the hard handoff procedure, and the resolution of a glare condition.Type: GrantFiled: May 27, 1997Date of Patent: March 22, 2005Assignee: Qualcomm IncInventors: Rajeev Krishnamurthi, Bibhu P.

Patent number: 6714597Abstract: A system and method for reducing the interference experienced by sensitive electronic devices, such as hearing aids, operative in the vicinity of CDMA user communication devices. A transmitter of the communications device is configured to transmit signal power substantially continuously at a full rate power level irrespective of the variable data rate at which the transmitter would otherwise be operative. In a first embodiment, a variable rate vocoder within the transmitter is directed to perform full-rate vocoding, irrespective of an instantaneous level of user speech. In a second embodiment, a microprocessor builds full-rate frames using repeated versions of code symbols generated by the vocoder. In a third embodiment, the microprocessor builds full rate frames by generating signaling bits of a predetermined pattern to pad otherwise non-full frames.Type: GrantFiled: September 1, 2000Date of Patent: March 30, 2004Assignee: Qualcomm IncorporatedInventors: Franklin Antonio, Robert D.

Publication number: 20020132622Abstract: A method and apparatus for operating a cellular telephone system that supports performing an inter-system soft handoff is described. A subscriber unit generates a pilot strength measurement report when the pilot channel from a base station is detected. When a base station controller receiving the pilot strength measurement report determines that the base station is part of a second cellular telephone system, a inter-system soft handoff request is generated. An admission control subsystem receives the inter-system soft handoff and either grants or denies the request base on the traffic level with the second cellular telephone system. In a preferred embodiment of the invention, the traffic level is determined based on link load messages received periodically by the admission control subsystem that are generated by an interface port coupled to an interconnect between the first cellular telephone system and the second cellular telephone system.Type: ApplicationFiled: October 30, 1999Publication date: September 19, 2002Inventors: PAUL E.

Publication number: 20010040965Abstract: A method for generating a broadcast challenge value includes the steps of applying a first updating algorithm to the most significant bits of the broadcast challenge value, and applying a second, distinct updating algorithm to the least significant bits of the broadcast challenge value. The updating algorithms can be maximal-length shift registers or other forms of pseudorandom noise generator. The sequence of successive unrepeated values can be extended for either one or both sets of bits by inserting an all-zeroes value once during the period of time before which an update value recurs. System-wide synchronization can be achieved via a global time reference.Type: ApplicationFiled: July 26, 2001Publication date: November 15, 2001Inventor: Roy F. Quick

Patent number: 6208857Abstract: The mobile telephone system employs a fleet of satellites and a set of gateway ground stations arranged around the globe for handling communications to and from mobile communication units such as mobile telephones. Signals are transmitted between a subscriber unit and the nearest gateway via one or more of the satellites. The gateway is connected to a set of individual service providers such as local telephone systems. The individual service providers may be constrained for various reasons such as contractual or other legal constraints to handle communications only from subscriber units located in certain geographical areas such as within only certain countries or portions of countries. For a mobile communication from a particular subscriber unit, the gateway selects a service provider capable of handling the communication. In one implementation, the selection is based upon the location of the subscriber unit and upon any preferences specified by the subscriber unit.Type: GrantFiled: November 4, 1996Date of Patent: March 27, 2001Assignee: Qualcomm IncorporatedInventors: Daniel H.
