Publication number: 20070184866Abstract: A method and mobile device for decoding a paging message transmitted as multiple bursts in a wireless communication system are provided. In the method, only the first burst among four bursts of a transmitted paging message is received and equalized. The equalized first burst is compared (e.g., by computing correlation) with a reference paging message. The first comparison result value obtained from the first comparison is compared with a threshold value. If the first comparison result value is greater than the threshold value, second through fourth bursts of the paging message are not received, and a previous decoded paging message is output and a sleep state is entered. If the comparison result value is not greater than the threshold value, the second through fourth bursts are received and decoded, the decoded paging message is encoded, and a first burst of the encoded paging message is stored as the reference paging message.Type: ApplicationFiled: December 5, 2006Publication date: August 9, 2007Inventors: Hee-Su Kim, Dong-Wook Seo, Il-Yong Jong

Patent number: 7254397Abstract: An apparatus and method for communications of scheduling information of reverse link transmissions are disclosed. A base station controller determines scheduling of a reverse link supplemental channel transmission for a mobile station in a communication system (100). The base station controller groups the mobile station in a group of mobile stations and assigns a forward link channel assignment channel to the group of mobile stations. A transceiver (400) incorporates information relating to the determined scheduling in the assigned forward link common assignment channel and transmits the assigned forward link common assignment channel to the mobile station for scheduling the reverse link supplemental channel transmission. The mobile station receives the assigned forward link common assignment channel.Type: GrantFiled: June 8, 2004Date of Patent: August 7, 2007Assignee: Qualcomm, IncorporatedInventors: Edward G. Tiedemann, Jr., Sai Yiu Duncan Ho, Jun Wang, Ragulan Sinnarajah, Ramin Rezaiifar

Patent number: 7248900Abstract: A manner of providing ring-tune alerts to announce the arrival of incoming communications at a communication device such as a mobile station operable in a wireless communication network. When notification an incoming communication arrives at the mobile station, the mobile station detects the type and origin of the communication and then composes a ring tune enhanced to provide incoming call information to the subscriber. The enhancement may include temporarily compounding the ring tune, tonal or stylistic enhancement, applying compound accompaniment, or applying tempo variation. The ring-tune components may be installed by the manufacturer or distributor of the instrument, or may be downloaded by the subscriber. The communication device may also be a personal computer operable to communicate through a communication network such as the Internet.Type: GrantFiled: November 18, 2003Date of Patent: July 24, 2007Assignee: Nokia CorporationInventor: Douglas Deeds

Patent number: 7203509Abstract: A method for managing communication sessions in a packet-oriented communication system, consisting of a central control unit and a plurality of mobile stations, which can be interconnected via the central control unit. To achieve this, a communication session is established between mobile stations that are assigned to a first communication group. Session priorities are then defined for a first mobile station of the first communication group, said station being in addition assigned to at least a second communications group. Finally the session priorities are transmitted to the central control unit. A second communication session is also established between those mobile stations that are assigned to the second communication group(s), including the first mobile station. Both the first and the second communication session are established via the central control unit, in such a way that the latter can manage the first mobile station in both communication sessions according to the transmitted session priorities.Type: GrantFiled: December 22, 2004Date of Patent: April 10, 2007Assignee: Siemens AktiengesellschaftInventors: Thomas Gottschalk, Eric Hilf, Olaf Kautz

Patent number: 7177907Abstract: Messages with a valid range are selected by a message filter unit among the messages received through a network by a message reception unit, and the selected messages with a valid range are temporarily stored in a message storage unit. A message delivery assessment unit compares periodically the valid range of the stored message with a valid range with a current position obtained by a positioning unit, and a message delivery unit delivers the message with a valid range for which the current position is in the valid range, to a user. As a result, the message reception device can deliver the message valid in a specific location to the user with an appropriate timing.Type: GrantFiled: January 14, 2002Date of Patent: February 13, 2007Assignee: NEC CorporationInventor: Kazuhiro Sakata

Patent number: 7177594Abstract: A mobile ad hoc network may be established between a plurality of devices that have common contacts on their contact lists. The contact lists may be conventional contacts stored in a list of contacts on a scheduling and information management or other software packages in one embodiment. Communications with various devices is limited to those devices listed on the list of contacts. Modification of those lists of contacts is controlled on a password-protected basis in one embodiment. Thus, a parent, for example, may limit the ability of child users to contact or be contacted by and communicate with unauthorized persons.Type: GrantFiled: September 6, 2001Date of Patent: February 13, 2007Assignee: Intel CorporationInventor: Jeremy Burr

Patent number: 7164888Abstract: The invention provides systems and methods for analyzing critical circuits and telecommunication resources. For example, in accordance with one embodiment of the invention, a computer-implemented method is provided for identifying critical telecommunication resources. The method includes identifying a set of critical telecommunication circuits, using a computer to search a first database for information about the set of critical circuits, and storing the information in a second database. In one aspect, the information can identify a set of telecommunication resources associated with the set of critical circuits.Type: GrantFiled: December 23, 2002Date of Patent: January 16, 2007Assignee: Qwest Communications International Inc.Inventor: Dieter Zerressen
