  • Patent number: 6404736
    Abstract: A method and apparatus enables a Network Access Server together with a telecommunications switch to route incoming calls only to devices that have sufficient resources to provide a connection to the Internet. A set of devices, RPs, reformat incoming data from subscribers to a desired Internet Protocol. During operation, each RP performs self-checks to determine whether sufficient resources exist within the RP for providing Internet communication. An example of such a resource is an Internet protocol (IP) address pool. Each RP may have several IP address pools that are associated with individual Internet service providers (ISPs). If, for example, an individual ISP's IP address pool is depleted within a particular RP, then that RP signals as much to call routing logic. The call routing logic will not route calls for that individual ISP to that particular RP until the call routing logic receives another signal indicating that the depleted resource has been replenished.

  • Patent number: 6374111
    Abstract: A system and method are presented for optimally retuning channel equipment in a base station serving a cell from a first channel group to a second channel group, without dropping pending calls and maintaining channel separation throughout the retune above a predetermined threshold. A sequential order for retuning the channel equipment is determined which insures that every channel equipment is retuned to a channel that is separated from the operating channels of each other channel equipment in a cell by a certain threshold. After determining the appropriate order, the status of each channel equipment is checked to determine whether the channel equipment is busy or idle. Based on the status of each channel equipment, the channel equipment are simultaneously retuned in groups of the size equivalent to the number of idle channel equipment in the determined sequential order.

  • Patent number: 6219557
    Abstract: A telecommunications system and method is disclosed for enabling a General Packet Radio Service (GPRS) node, namely a Serving GPRS Support Node (SGSN) within a cellular network, to be able to handle requests for Location Services (LCS) for a GPRS mobile station (MS) in parallel to other existing transactions such as delivering short messages or engaging in session management activity, e.g., data call connection. A new LCS transaction type can be introduced in the Connection-Management (CM) sub-layer of GPRS in the SGSN and the GPRS MSs to handle requests for LCS in parallel to other offered services. LCS can be multiplexed together with other existing functions in GPRS by allocating a new Service Access Point Identifier (SAPI) to LCS within the Logical Link Control (LLC) sub-layer of the GPRS. Alternatively, when a common LLC SAPI is used between different CM-sublayer functions, then a different protocol discriminator (PD) can be allocated for LCS.

  • Patent number: 6159186
    Abstract: Apparatus for providing control of infusion delivery using conventional infusion fluid bags includes an air bag which is pressurised by a pneumatic pump. A digital camera or imaging device is able to analyse drops passing through a drop chamber, by capturing an image of the drop as it passes through the drop chamber. The output of the imaging device is fed to an image processor which calculates the volume of the captured drop using the number of pixels in the image. An infra red detector detects each time a drops passes through the drop chamber, and the outputs of the both the image processor and the infra red detector are passed to a master controller. The master controller controls the fluid delivery process by counting the number of drops passing through the drop chamber and controlling a flow brake to achieve the required flow rate.

  • Patent number: 6158737
    Abstract: A pinball machine has been designed with several novel mechanical and electrical features such that it is easily retrofittable or convertible between a first pinball game and a second pinball game. One of these features is a novel playfield assembly for the pinball machine. For ease of movement of the playfield into and from a cabinet of the pinball machine, the playfield has skid rails which extend substantially along the length of the playfield. The skid rails are spaced from the lower side of the playfield by a distance that is greater than the distance by which components protrude from the lower side of the playfield. Thus, the playfield can be placed on the ground without any chance for damage of its components. The playfield may also include a slide stop at one or both of its ends. The slide stops engage the front molding of the cabinet to ensure the playfield does not fall into the cabinet or fall from the cabinet as the skid rails are being slid across the front molding.

  • Patent number: 6151498
    Abstract: A telecommunications system and method is disclosed for allowing a Gateway Mobile Positioning Center (GMPC) to route positioning requests to the Public Land Mobile Network (PLMN) where the subscriber is currently located without the need for storing the subscriber's serving Mobile Positioning Center (MPC) address in the Home Location Register (HLR). When an external Requesting Application (RA) wants to locate a particular Mobile Station (MS), the RA contacts the GMPC, and provides the directory number of the subscriber that needs to be located. The GMPC then sends a request for routing information, e.g., the address of the serving Mobile Switching Center (MSC), to the subscriber's HLR. The HLR then returns the routing information to the GMPC, which can then send the positioning request to the serving MSC, using the MSC address. The serving MSC can then route the positioning request to the serving Mobile Positioning Center.

  • Patent number: 6139198
    Abstract: A system and method for enabling a tracing of program execution within an object-oriented programming language environment. A new tracing class is created which is derived from the original class. When tracing is desired, a user creates instances of the tracing subclass instead of the original class and this instance is used in place of the original object. When tracing is not desired, a user merely creates and uses an instance of the original class. The new tracing subclass incorporates "print" statements, which permit observation of the control of code flow within the object.
