Abstract: A method of sending a call transfer notification (CTN) to a mobile station (MS) in a radio telecommunications network. The CTN indicates that a call transfer feature is activated, and is displayed on the MS display until the call transfer feature is deactivated or the MS is turned off. The network includes a serving Mobile Switching Center (MSC) which serves the MS, and a Home Location Register (HLR) which stores a subscriber profile associated with the MS. The method begins by storing in the subscriber profile, a CTN Active parameter that indicates whether or not the CTN should be sent to the MS whenever the MS is powered up. A CTN Type parameter is also stored in the subscriber profile and indicates which type of call transfer feature is activated. When the HLR is notified that the MS has been powered up, the CTN Active parameter is checked in the subscriber profile to determine whether the CTN should be sent to the MS.

Abstract: A system and method of optically inspecting structures on the surface of an object, such as a semiconductor wafer. A platform is used to support the object under examination, and provided thereat are lights or other energy sources for illumination disposed at a selected angular orientation. Optimum illumination is achieved by orienting two opposing lateral energy sources to direct energy along the surface of the object at a very low angle, and using them in conjunction with a coaxial light source that emits energy, which is directed downward toward the surface. Energy reflected back from the surface is captured as an image by a suitable device such as a CCD camera. The lighting may be controlled by an attached computer, which can also be used to process and store the captured image and analyze it to detect and catagorize defects in the object being inspected.

Abstract: A system and method in a radio telecommunications network for automatically conveying a Wireless Office System (WOS) frequency set to a mobile station (MS) belonging to the WOS. The network includes a public cell, and a private WOS located within the public cell. A WOS controller sends the WOS frequency set from the WOS to an Equipment Identity Register (EIR) in the network whenever the WOS changes its frequency set. When the MS registers in the public cell in which the WOS is located, a mobile switching center (MSC) serving the public cell notifies an Intelligent Roaming Database (IRDB) of the registration. The IRDB fetches the WOS frequency set from the database, and obtains location information for the MS from a home location register (HLR). The IRDB then sends the WOS frequency set to the MS in an IS-136 R-DATA message.

Abstract: A method of reducing speech delay and improving speech quality in digital transmission systems by implementing a single coder-decoder (codec) for an entire speech path from a calling party to a called party. The method is applicable to calls between mobile subscribers and between a mobile subscriber and an H.323 client terminal in a data network. After obtaining location information for the called party, an indication of a requested codec is sent from the calling party to the called party utilizing Integrated Services Data Network User Part (ISUP) or Primary Rate Interface (PRI) out-of-band signaling during call setup. If the called party supports the requested codec, a confirmation of the requested codec is sent from the called party to the calling party. A speech path is then established between the parties, and a single codec translation is performed for the entire speech path.

Abstract: A system and method of correlating alarms from a plurality of network elements (NEs) in a large communications network. A plurality of uncorrelated alarms are collected by an alarm collector from alarm reporters. An alarm correlator then partitions the alarms into correlated alarm clusters such that alarms of one cluster have a high probability that they are caused by one network fault. The partitioning of the alarms is performed by creating alarm sets, expanding the alarm sets into alarm domains, and merging the alarm domains into alarm clusters if predefined conditions are met. The sets are formed by selecting an alarmed NE at the highest network hierarchy level which is not tagged, finding all of its contained NEs, and finding NEs that are peer-related to those contained NEs that are in an alarmed state. The sets are expanded into domains by finding NEs that are not in an alarmed state which contain the highest level alarmed NE in each alarm set.

Abstract: A system and method for preparing semiconductor samples for analytical techniques such as backside emission microscopy. Samples may be prepared from a wafer or packaged die. In package form, the package is affixed to a polishing jig such that the backside of the die is oriented to face a polishing wheel. The package material is removed until die attach paddle and the backside of the die are exposed. The material is further removed until a selected thinness of the die is obtained. If the package's leadframe or a portion thereof remains after the removal of package material, a suitable testing fixture is attached thereto. If the leadframe is sacrificed, wire spots on the polished side of the semiconductor die are wire-to-wire bonded to a second leadframe's conductive fingers. In wafer form, the die is separated and encapsulated with a suitable substantially rigid material to form a substantially rigid body that is affixed to the polishing jig.

Abstract: An apparatus, system, and method of optically inspecting printed circuit boards (PCBs) for defects, that reliably determines the dimensions of components including those having the same color as the background, and which can detect components which are missing, misoriented, misaligned, or not properly seated. The apparatus uses a camera and a coherent primary light source mounted at an angle away from the vertical so as to produce sharply defined PCB component shadows on the top surface of the PCB. An image of the PCB is captured, the shadow edges are symbolically decomposed into primitives from which gradients are produced, and then compared to a previously captured gradient of a defect-free PCB. Differences in the two image gradients, if any, are used to identify missing, misaligned, misoriented, and improperly seated components, and to detect foreign objects and other PCB defects.

Abstract: A method of sharing capabilities information between a plurality of nodes in a telecommunications network. The method begins when a new node is installed in the telecommunications network or the capabilities of a node are modified. The new or modified node sends an Exchange Data Directive (EXDATADIR) Invoke message to one or more cooperating nodes in the network. The EXDATADIR message is an intersystem node capabilities declaration message which includes parameters relating to communications capabilities and service support capabilities of the new or modified node. If the node is a new node, this is followed by sending EXDATADIR Return Result messages from each cooperating node to the new node. The EXDATADIR Return Result message is an intersystem node capabilities declaration message which includes parameters relating to services supported by the cooperating nodes.

Abstract: A system and method in a radio telecommunications network for reconnecting an emergency call between a roaming mobile station with an emergency (emergency MS) and a public safety answering point (PSAP) when the call has been disconnected before the call was finished. The network includes a serving mobile switching center (MSC) serving the emergency MS, a border MSC bordering the serving MSC, and a home location register (HLR) that stores features and subscription data for the emergency MS. When the emergency call begins, a hotlining feature for the emergency MS is activated in the HLR which automatically reconnects the emergency MS to the PSAP when the MS accesses the network through a registration or by originating a subsequent call. Inter-exchange messages ensure that the emergency MS is automatically connected to the PSAP, even if the emergency MS accesses the network in the border MSC.
