Patent number: 7801494Abstract: A Push-to-X over Cellular (PoC) server (351) receives a server registration message (301) for a first called device from a second server. The PoC server (351) receives a PoC invitation message (310) with PoC preferences and a message (313) from an originating device (311). The PoC preferences determine what device to call first (e.g., a mobile device 315, 317) and how many hops the call can be forwarded (e.g., to a voicemail server) if the first-attempted device is not available, before discontinuing the connection. If a trigger, such as time elapsed, occurs for the first-attempted device (350) and the PoC preferences permit, the PoC server (351) sends an invitation message (360) to the second server (391). If the second server (391) is a recording server, the invitation message (360) includes a message (363) from the originating device that is compatible with the capabilities of the recording server (391).Type: GrantFiled: May 27, 2005Date of Patent: September 21, 2010Assignee: Motorola Mobility, Inc.Inventors: John E. Emrich, Balakumar Jagadesan

Patent number: 7792544Abstract: A method and apparatus for an electronic device (100) monitors one or more inputs to the device, such as a transition in sensed ambient light (170)and key press sequences (180), to determine when to lock the device (100). The device memory (155) may include a matrix (or dictionary or rules) of valid, questionable, and invalid inputs that may be updated from time to time. When a questionable input is received, the device (100) notifies a user to enter an exit trigger, such as a MENU * key sequence, or else the phone will be locked. By using a variety of factors to discern questionable inputs and by presenting an exit trigger upon receipt of a questionable input, the electronic device will not lock when a user enters the exit trigger after a questionable input but will lock otherwise.Type: GrantFiled: May 25, 2007Date of Patent: September 7, 2010Assignee: Motorola, Inc.Inventors: Jerome O.

Patent number: 7786901Abstract: A method for key press registration in an electronic device uses a first key press debounce limit (233) if a first housing of the electronic device has not moved relative to a second housing of the electronic device and a second key press debounce limit (236) if the first housing has moved relative to the second housing. In one implementation, the second debounce limit is at least twice the first debounce limit. By using different debounce limits based on whether housing movement has recently been detected, the electronic device reduces the effect of an inadvertent key press made while opening or closing the electronic device.Type: GrantFiled: April 3, 2007Date of Patent: August 31, 2010Assignee: Motorola, Inc.Inventors: William P. Alberth, Jr., Daniel Herscovici

Patent number: 7757148Abstract: A method (100) of operating an Automatic Repeat Request (ARQ) transmitter (102) and an ARQ receiver (104) suspends an ARQ reset under circumstances where an ARQ reset would be superfluous. When a transmitter has a final currently-available data block, it deactivates its transmitter ARQ sync loss timer (172) and transmits a ‘suspend ARQ reset’ signal (122). Upon receipt of the ‘suspend ARQ reset’ signal (122), the receiver deactivates its receiver ARQ sync loss timer (176) and sends ARQ feedback (128). At this point, the ARQ connection can be maintained without superfluous ARQ resets even when no ARQ data blocks are being sent. When resuming transmission of ARQ data blocks, the transmitter activates its transmitter ARQ sync loss timer (182) and transmits an ARQ data block (142). The receiver receives the ARQ data block, activates its receiver ARQ sync loss timer (186) and sends ARQ feedback (148).Type: GrantFiled: May 25, 2006Date of Patent: July 13, 2010Assignee: Motorola, Inc.Inventors: Wim Schaap, Marcel Korndewal, Leon J. Zegers

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
