Abstract: Present-day on-line charging mechanisms make it possible, in a non-blocking application, for the setting up of a connection to be allowed initially even though it is not yet clear, or cannot be clarified at this time whether a prepaid subscriber (SIP client) still has sufficient money in his account. This therefore leads to a call being signalled to a subscriber (Subs) to be called (it rings), and the call must then be cleared if there is not enough money in the account. In order to avoid this “ghost ringing”, but nevertheless to ensure that connections are set up quickly, a method is proposed which includes an address element, for example the last digit, being withheld, until authorization is obtained from the On-line Charging System (OCS). Alternatively, a connection is set up with a prior condition of “do not ring”, in accordance with IETF RFC 3212. The invention can also be used for other non-monetary authorizations, for example for “lawful interception”.

Abstract: The invention relates to an interworking between two protocols in a network with a first user, corresponding to the first protocol and a second user corresponding to the second protocol, achieved whereby a third protocol serves as interface between the Media Gateway Controllers (MGC) involved. A connection between the both users is achieved by means of at least one user channel in each of the transmission and receive directions. Performance features, the operation of which provide a resolution of the user channels, which, on initiation of the performance features, are provided with a command set directed at the second user by the first user with the aim of interrupting the user channel coming from the second user with respect to the first user.

Abstract: A contact element for the intermittent contacting of conductor tracks on a circuit board, in particular, for flexible touchpads, for example for flexible input devices in the automobile industry, is made from a metal foam. The metal foam may be at least partly infiltrated by an elastomeric material which can also be the material of construction of the touchpad. The contact element has a very reliable construction which is particularly suitable for high voltage application. A method for production of the contact element, touchpads/input devices with such contact pads and the use of the contact pads is also provided.

Abstract: The prior art cannot implement the feature call hold in a FMC network (fixed mobile conversion, i.e. mixed mobile fixed networks). This is due to the fact that the feature call hold as well as the features conference calling and three-party service have different definitions in the two standards ITU-T Q1912.5 and 3GPP TS 24.228 with which incompatible procedures are defined. Compatibility problems arise since all involved units in the FMC networks with different units such as clients and network transition units necessitate an inter-working of all interlinked units. This problem is resolved by providing a mapping functionality that converts the protocol elements of both standards into one another.

Abstract: The invention concerns a method for setting up a multimedia connection via a packet-switching computer network between at least one first calling subscriber (A-Tln) and at least one first called subscriber (B-Tln), the called subscriber terminal (B-Tln) triggering a cascade call transfer to other subscriber terminals (C-Tln, D-Tln). The invention is characterized in that the multimedia connection of the calling subscriber (A-Tln) to the terminal of the first called subscriber (B-Tln) is first set up via a network element (PR) of the computer network. Then, the terminal of the first called subscriber (B-Tln) transmits to the network element (PR) the connection transfer to another terminal (C-Tln, D-Tln) and the data associated with said other subscriber terminal (C-Tln, D-Tln). The network element (PR) then retransmits, while maintaining the multimedia connection to the calling subscriber (A-Tln), the setting up of the connection to said other subscriber terminal (C-Tln, D-Tln).

Abstract: In a method for tracking postal items, the shipping details of each postal item are stored in a data base that can be interrogated and is updated during shipping. A data record which can be changed and completed is created in each original distribution center and for each postal item that is posted in the center. The data record contains a reference number and data that characterize the postal item and the shipping details. Each posted postal item is provided with an identification key in the original distribution center. The key uniquely characterizes the postal item. The postal items are transported to the destination distribution center, optionally via additional distribution centers. The reference numbers and the original distribution centers are subsequently detected in said succeeding distribution centers and the relevant shipping data including the reference numbers is electronically transmitted to the original distribution centers for completing the data records.

Abstract: A power supply power supply (30) comprising a DC voltage supply, a control unit and a plurality of high voltage channels (33a-33d) is suggested. Each high voltage channel (33) includes an inverter (IKTV), a resonance circuit, a transformer (TR), and a rectifier (RECT). The resonance circuit cooperates with the inverter (INV). The inverter (INV) is formed by a first switching unit and a second switching unit whereby a voltage of a first polarity can be applied to the resonance circuit in a first switching state, whereas a voltage of a second polarity can be applied to the resonance circuit in a second switching state. The switching states can be switched by the control unit in such a manner that in a first mode of an operation for high output power, the output power can be adjusted by changing the switching frequency in the range of the resonance frequency.

Abstract: In a method for securing communication links and associated charging in a redundantly configured communication network in which terminals communicate via bearers, and via hardware units by means of messages, a monitoring function is used to monitor a correct functioning of at least one of the terminals, the bearers and the hardware units. If at least one of the hardware units fails, a physical function of a failed hardware unit is taken over by at least one functional hardware unit. After takeover, a message is transmitted by the at least one functional hardware unit to a terminal affected by a failure. The at least one functional hardware unit establishes that the monitoring function is executed by the at least one functional hardware unit. If a transaction is ongoing, a signal from a failed hardware unit is transmitted to a functional hardware unit such that overcharging for the transaction is avoided.

Abstract: In one aspect, a method for establishing a multimedia connection between at least one calling user and at least one called user via packet-oriented computer networks is provided. The users independently recognize contradictory requests of the calling user and the called user to each other and then send a request for delaying execution of the respective task to the respective call partner if contradictory requests occur.

Abstract: The invention relates to a method for providing IVR (interactive voice response) resources using the BICC protocol. In the method according to the invention, the provision of IVR resources is triggered in a CMN (call mediation node). The CMN brings about the execution of the BEARER REDIRECTION BICC procedure at an SN (service node) arranged upstream of it, and brings about access to IVR resources by means of the BICC procedure. The method according to the invention enables IVR resources in BICC networks to be provided directly at a CMN for the first time.

Abstract: The invention relates to a system and method for changing protocol parameters of a signaling protocol for the implementation of services in an Intelligent Network concept with user data transfer via a packet network. Resources are provided in a service control point for parameter changes to be made in the context of the services to the signaling protocol used. Implementation of a service, which requires a change to a protocol parameter in the signaling protocol, correspondingly adapted intelligent network application part procedures are used by a service switching point to trigger the parameter changes to be made in an service control point and the change to the protocol parameter is effected by the service control point in the service switching point. The invention has the advantage that it allows parameter changes, which are not provided in the ISDN user part because of their relationship with the packet network.

Abstract: According to prior art, name information is displayed instead of dialling information, by means of the Name Delivery feature, for subscribers to conventional TDM CENTREX communication architectures. The mixed operation of TDM/SIP CENTREX communication architectures does not yet support this feature. The invention remedies this in that the name information is transmitted in protocol elements of the SIP protocol and is supplied to the called subscriber by means of a logic. Said logic determines whether the information is displayed or not.
