Abstract: A method for setting-up a data connection during a group voice service between several group members as a user of a mobile communication network. In a first method, functions of an IP multimedia subsystem (IMS) are used and a session initiation protocol (SIP) and a controlled data connection between an emitter, a terminal and one or several receivers is produced. Each user is allocated to a group voice service identity (VGCS-ID) an IMS group identity (IMS group ID) and is routed to an application server in the IMS with the aid of the user. A data group voice service is developed between the users. In a second method, each user is routed to the service nodes via GPRS using a group voice service identity (VGCS-ID) and an IP address of a service node, which acts as a relay and a data group voice service is carried out between the users.

Abstract: The invention at hand involves a method and an arrangement for optimizing the operational times and cell exchange performance of mobile terminals in a mobile communication network having adjacent radio cells. The mobile terminal temporarily stores network specific characteristics for adjacent radio cells which are not suitable for cell exchange when the mobile communication network is in operation and it uses said characteristics as decision criteria for cell exchange, and said information is used, in particular, to exclude said adjacent radio cells from additional radio technical measurements and identification methods. By implementing the terminal performance according to the inventive method, it is possible to significantly increase the operational times and the cell exchange performance of a mobile terminal in specific situations and to improve the service for a mobile radio customer.

Abstract: A method for guaranteeing the quality of services in packet-switching radio communications networks. The radio access network (RAN) and the core network (CN) use the quality of service information independently of one another, without signalling individual parameters, in order to guarantee the transmission of packets in the uplink and downlink according to the quality of service. This is achieved exclusively using local settings that have been configured for individual TCLs, permitting a radical reduction in complexity compared to conventional methods. The method is further simplified by the described interlinking of different tasks or the linking of such tasks to an existing data transmission.

Abstract: The present invention relates to a method for generating a space-related traffic database for a radio network which comprises a plurality of radio cells which can each be assigned to a group of radio cells, with a region to be mapped being subdivided into area elements by a grid and each of the area elements being allocated a respective assignment probability for each of the radio cells which supply the area element and a land-use class from amongst a finite group of land-use classes by generation being achieved by a minimization process in which the distance between the measured traffic of a radio cell and the predicted traffic of the radio cell is minimized for each radio cell, with the traffic, which is to be predicted, of a respective radio cell being set equal to the sum of area elements which are weighted by land use class-specific and group-specific coefficients, which area elements of the respective radio cell for a respective land-use class and for a respective group of radio cells are produced from

Abstract: The invention relates to a method for controlling resources in network elements of a communication network, in particular a data network or a mobile data network. The idea of the invention is the use of a data packet inspection for the Quality of Service (QoS) control in telecommunication networks. Based on information obtained from data packets, a network resource corresponding to the content of each data packet is provided in the network elements. A dynamic allowance for services and customer classes or quality and resource control is a novel possibility by means of the above application of packet inspection.

Abstract: The invention relates to a method and a device for setting up and billing a roaming communications connection between a first calling subscriber of a first communications network and a second called subscriber of the first and or another communications network who is checked into a roaming communications network. Billing data records concerning the accrued costs of the roaming connection are generated by the communications networks, are exchanged between billing systems of the communications networks, and the subscribers arc charged the costs of the roaming connection on the basis of the billing data records. According to the invention, the costs for a connection, which originates from the first, calling subscriber and which is incoming to the second, called subscriber are charged exclusively to the first subscriber under conditions individually agreed upon beforehand.

Abstract: A method and a device for automatic route registration. A destination is entered into a data input device. A route is determined as a function of a starting location and the entered destination. The first route is transmitted to a route analysis device and divided into at least one route section therewith. The route section is registered in an evaluation device. Upon the detection of a first condition, a second route is determined to the destination. The second route is automatically transmitted to the route analysis device. The route analysis device compares the second route to the first route. Unused route sections of the first route are cancelled and added route sections of the second route are registered.

Abstract: A method for informing a subscriber of a mobile telephony network about incoming calls while the mobile telephone of the subscriber is switched off or is not connected to the mobile telephony network. The notification takes place via the mobile telephone of the subscriber as soon as the mobile telephone has re-registered itself in the mobile radio network, and the message including at least the call number of the missed caller. In the event of a calling line identification restriction (CLIR) from the caller, a message is automatically produced and sent to the caller, by which means the caller is prompted, by a dialogue, to temporarily release the call number transmission for the call, such that the call number of the caller can be communicated to the subscriber.

Abstract: The invention relates to an electronic toll system for traffic routes, said system being designed on the basis of commercial GSMIUMTS mobile telephones or comparable appliances such as a PDA, car phones etc., with a GSM function, and to a method for the operation thereof. In each mobile radio network, data of the respective radio cell is transmitted to the radio telephone via an organization channel. According to the invention, said information supplied by the base transceiver stations is used to record the radio cells crossed by the toll customer. The collected data is transmitted to a central toll station. The toll traffic route taken by the vehicle can be deduced with high precision, by comparison with databases relating to existing traffic routes, on the basis of the series of crossed radio cells transmitted by the terminal of the toll customer. According to the invention, no changes need to be carried out on the hardware of current mobile radio systems and terminals.
