  • Patent number: 7672676
    Abstract: A method and system for obtaining the position of a mobile station located in a current network of a communications system including a plurality of networks supporting different positioning protocols. The current network is identified at a location center based on the identified current network. A suitable positioning protocol is selected among at least two protocols for communication of location information with the current network.

  • Publication number: 20090121438
    Abstract: A method for teams having one or more players each to play poker tournaments (101) The teams start with the same number of chips and, when the tournament starts, each team is allocated a certain number of seats (103) The chip stacks respectively allotted to a team's allocated seats belong to the seats, not the players (107) Players can be moved between seats, but players from the same team are not allowed to sit at the same table (215) When a player loses such that his or her chip count is zero (301), the team loses that seat (303), but the losing player can be moved to another seat at another table, if desired When a team has lost all of their seats, that team is out (307), (309) The size of the tables during the tournament may vary The ranking of the teams is based on their respective total number of chips, active seats or combination of chip and active seat totals

  • Patent number: 7103361
    Abstract: Method and system for planning and/or evaluation of cell capacity in (CDMA) radio networks comprising at least one base station that defines at least one cell. Both uplink cell capacity estimations and downlink cell capacity estimations can be made by adding amounts of traffic to the cell until a limiting capacity representative value has been reached.

  • Patent number: 7076250
    Abstract: Method and system for planning and/or evaluation of downlink coverage in a (CDMA) radio network. A service area of the radio network can be divided into pixels defined by a grid, and cells can be assigned to the pixels. After assigning pilot power, desired downlink transmission power can be estimated for the cell, which can then be compared to maximum transmission power of the base station. If needed changes in the radio network are to be made, the planning and/or evaluation is restarted.

  • Publication number: 20060099958
    Abstract: A method and system for obtaining the position of a mobile station (1) located in a current network of a communications system including a plurality of networks supporting different positioning protocols. The current network (6) (107) is identified at a location centre (2) based on the identified current network (6), a suitable positioning protocol is selected among at least two protocols for communication of location information with the current network (6) (108).

  • Patent number: 6985735
    Abstract: Method and system for the planning and/or evaluation of radio networks, especially CDMA radio networks. The service area of a radio network is divided into pixels after which for each pixel a probability is determined whether it is covered by a cell of the radio network. To account for cell breathing due to traffic changes, the planning involves the calculation of a link budget for each pixel and of a noise rise for each cell.

  • Publication number: 20030148782
    Abstract: Method and system for the planning and/or evaluation of downlink coverage in a (CDMA) radio network. The service area of the radio network can be divided into pixels defined (a) by the grid (1), and cells (2) can be assigned (b) to the pixels. After assigning (c) the pilot power (3), the desired downlink transmission power (4) can be estimated (d) for the cell (2), which can be compared (e) to the maximum transmission power (5) of the base station. If needed changes in the radio network can be made and the planning and/or evaluation is restarted.

  • Patent number: 6438719
    Abstract: A method and system for testing a memory in operation. A storage unit is used to temporarily free one memory location in the memory, making it possible to check this memory location for bit errors. Data intended for the selected memory location is stored in the storage unit, and instead a test pattern is written into the memory location to be tested and read out again, all in coordination with the normal operation of the memory. If the pattern read from the test location does not match the written test pattern, an alarm is raised.
