Patent number: 7643838Abstract: An integrity protection count synchronization method (200) initiates (210) a new connection when a user equipment (UE) is already in connected mode with a network. If new security keys are pending, the UE sends (250) a START value of zero in an initial direct transfer message. If no new security keys are pending, the UE sends (240) a non-zero START value based on a Universal Subscriber Interface Module (USIM). Sending a START value of zero when new security keys are pending at the UE forces the network's COUNT-I integrity count value to match the zero COUNT-I value at the UE, which prevents call set-up failure due to inability to pass an integrity protection security check.Type: GrantFiled: September 29, 2005Date of Patent: January 5, 2010Assignee: Motorola, Inc.Inventors: Hui Zhao, Padmaja Putcha

Publication number: 20080130557Abstract: Mobile station applications (419) may include an SI unit (409) for piggy backing SI onto data stored in data buffer (421) and also for adding an indicator to the SI information. The scheduling information and/or incremental control information (501) is piggy backed onto a data PDU and also has a sequence number (503) and an indicator field (505) which is added by the SI unit, such as SI unit (409), in accordance with the embodiments. The indicator may be a bit map having four bit positions. A bit position having a binary “1” value may be utilized to indicate that a previous SN of SI information remains valid. For example, “0100” of the bit map sequence may indicate that SN #3 is still valid. The base station or controller may then determine whether to implement or discard an SI information having the indicated SN.Type: ApplicationFiled: November 30, 2006Publication date: June 5, 2008Applicant: MOTOROLA, INC.Inventors: Ravi Kuchibhotla, Padmaja Putcha

Publication number: 20080085719Abstract: A network controller or base station (502), allocates resources and indicates a minimum priority level below which, mobile stations may not transmit data via messaging (503). Messaging (503) may be a scheduling message in some embodiments. The network controller or base station (502) also communicates a data timer setting for timing sub-minimum priority data via messaging (505). Messaging (505) may be a control message in some embodiments. The mobile station (501) responds by setting a data timer (507) and holding data with a priority below the specified minimum. Before the timer times out, the mobile station (501) may transmit data on granted resources via (509) provided its priority level is above the specified minimum. After timer expiration, the mobile station (501) may transmit its low priority data, or combinations of high and low priority data (511).Type: ApplicationFiled: October 9, 2006Publication date: April 10, 2008Applicant: MOTOROLA, INC.Inventors: Ravi Kuchibhotla, Padmaja Putcha

Patent number: 7231213Abstract: While engaged in a dedicated channel, a User Equipment (UE) may get stuck on it. A method and the computer program product detects whether the UE is stuck on the dedicated channel (202). When it is detected that the UE is stuck, the UE or the corresponding network in which the dedicated channel is located carries out a local release of the UE from the dedicated channel (204), and the UE is placed in idle mode (206). Locally releasing the UE from the dedicated channel curtails unnecessary battery consumption in the UE and limits wastage of network resources and bandwidth.Type: GrantFiled: June 30, 2005Date of Patent: June 12, 2007Assignee: Motorola Inc.Inventors: Donald A.

Publication number: 20070033411Abstract: A security mode method (200) receives (210) a layer 3 message in a first domain from a network, determines (220) if the layer 3 message has integrity protection information, ascertains (240) if a security mode has been initiated in the first domain, and forwards (260) the layer 3 message to an upper layer, if the layer 3 message lacks integrity protection information and a security mode has not been initiated in the first domain even if security mode has been initiated in a second domain. This method allows a mobile station to process a non-integrity-protected layer 3 message from one domain even if integrity protection has been initiated in another domain. When packet-switched and circuit-switched connections are being concurrently set up, a non-integrity-protected message in one domain may arrive at a mobile station after an integrity protection initiation message in another domain.Type: ApplicationFiled: August 8, 2005Publication date: February 8, 2007Inventors: Hui Zhao, Padmaja Putcha
