Abstract:
The invention allows improving the control of transmission of the silence detection (SID) frames to prevent annoying effects in the music sent to the calling terminal instead of ringback tones. This can be achieved by disabling the discontinuous transmission functionality during the period of call establishment. There are many different ways to accomplish the idea behind the present invention.
Abstract:
The invention relates to a method and an apparatus for mixing audio signals. The invention is based on the idea to base selection of what audio channels to mix on the dynamic behaviour of the audio channels in terms of whether they are active or not, rather than basing the selection on quantative measures of the audio channels. According to the invention, a set of audio channels are arranged in a mixing stack and a mixed audio signal is produced from the topmost channels above a predetermined threshold level in the stack. Whenever a channel becomes active, it is placed at the top of the stack.
Abstract:
Methods, systems, and computer program products for detecting fraudulent message service message traffic are disclosed. According to one method, message service messages are monitored. It is determined that the message service message traffic indicates that the message service message traffic is fraudulent based on detection of at least one of: 1) message service message traffic received at a first network from a second network, where the traffic includes at least one message with an SCCP calling party address internal to the first network, 2) a volume of message service message traffic received at the first network from the second network that exceeds the volume of message service message traffic sent by the first network to the second network by a threshold amount, and 3) message service message traffic that is sent to a dark number. In response to detecting fraudulent message service message traffic, a mitigating action is performed.
Abstract:
Für ein Mobilkommunikationsendgerät ist eine periphere Funktionseinheit vorgehen, die über eine Schnittstelle des Mobilkommunikationsendgeräts mit diesem verbindbar ist. Die periphere Funktionseinheit ist derart ausgestaltet, daß das Mobilkommunikationsendgerät bei Trennung von zumindest einem Bestandteil der peripheren Funktionseinheit vom Mobilkommunikationsendgerät zu einem Übermitteln einer Notruf-Meldung an einen Notrufempfänger veranlaßt wird.
Abstract:
A consistency verification tool performs a consistency check on subscriber data records stored in the cellular telephone system. One such consistency check analyzes subscriber data records in a home location register (HLR) and a billing system to determine the presence of duplicate records. Duplicate records can be stored in a duplicate record file for later analysis. During the duplicate record consistency analysis, the consistency verification tool creates a record list. The record list can be a linked list structure for storing main records and duplicate records in a manner that facilitates identifying families of duplicate records. The consistency verification tool can also perform inter-device consistency checks. For example, the subscriber data stored on the HLR can be compared to the subscriber data stored in the billing system to ensure that the two systems have consistent subscriber data.
Abstract:
There is described a method of operating a fault management system for an access network which forms part of a communications network. In the access network, terminating lines in the form of pairs of copper wires extend from a local switch (10) through a series of nodes to terminal equipment provided for user of the network. The fault management system includes a test head (104) and an access network management system (102). Each night, the test head (104) performs a series of tests on each of the terminating lines. The results of the tests are transmitted to the access network management (102). The test results are then analysed with respect of a set of parameter to identify characteristics that would indicate that a fault is likely to occur on the associated circuit within a predetermined period e.g. 1 year. Further analysis can then be carried out to establish the probability of the fault actually occurring and/or whether the potential fault analysed is going to occur in either the underground or the over-ground part of the network.
Abstract:
The present invention comprises a method for audio/video conferencing including an audio conferencing platform (26), the platform comprising network interface cards (38-40), processing boards (44-46), a CPU (48), a TDM bus (42) and a PCI bus (50). The method comprises using dynamic threshold value to determine whether there is speech on a line. In one aspect, the method comprises determining a dynamic threshold value based on one or more chracteristics of signals received on a port, associating that dynamic threshold value with the port; and comparing one or more characteristics of signals subsequently received on the port to the dynamic threshod value. Signals received over a plurality of ports are summed, but for ports whose signal characterisics have a specified relationship to the dynamic threshold value associated with that port, signals are not contained in the sum.
Abstract:
Methods for dialing an emergency telephone number from a teleworking client according to the invention include detecting at the teleworking client when an emergency number is dialed, disconnecting the teleworking client from the PBX/MLTS, connecting the teleworking client to the PSTN, and dialing an associated stored number. The apparatus of the invention resides in software that is installed in off the shelf hardware. Though the invention is described with reference to a teleworking client, it may also be applied to any other dialup network connection.
