| 20080198992 | Method for Setting Up a Multimedia Connection In Case Of Cascade Connection Transfer - 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). The invention thus ensures in simple manner that a specific network element (PR) continues, notwithstanding the cascade call transfer, to participate in the setting up of the multimedia connection, thereby enabling the multimedia connection to be taxed, a legal interception to be performed and traffic measurements to be made. | 08-21-2008 |
| 20080225834 | Method for Supporting the Service Features "Call Hold", "Conference Calling" and "Three-Party Service" in Fmc Networks - 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. | 09-18-2008 |
| 20090201914 | METHOD AND SYSTEM FOR AUTHORIZATION CHECKING WHEN SETTING UP A CONNECTION - 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”. | 08-13-2009 |
| 20100220718 | Method for detecting calls and corresponding units - A method for detecting calls is disclosed. A call request initiated by a calling terminal device is received by an access unit of a called terminal device of a data packet transmission network. An invite message is sent from the access unit to the called terminal device. A 200-OK message from the called terminal device is received by the access device. In the event of a detection request, a detection message is received by the access unit in order to initiate a detection of the calling terminal device. Additionally, a telephone terminal device includes a controller, which responds with a 200-OK to an invite message, the terminal device sends a detection message to the access unit in order to initiate a detection of a calling terminal device. An access unit which automatically stores an identifier of a calling terminal device is also disclosed. | 09-02-2010 |
| 20100246447 | METHOD AND DEVICE FOR PROCESSING DATA AND COMMUNICATION SYSTEM COMPRISING SUCH DEVICE - A method and a device for processing data by a network element is provided, said method including the steps of (i) the network element receives information about an entity; (ii) the network element determines whether information associated with said entity is available; and (iii) if information associated with said entity is available, the network element initiates interception. Further, a communication system comprising such a device is provided. | 09-30-2010 |
