Abstract: We generally describe an audio-based line fault detection system for a sports game. The audio-based line fault detection system comprises one or more audio sensors (102) for sensing an audio signal generated by a sports gaming device bouncing off a sports field. The sports field comprises surface modifications applied to a line and/or an area adjacent to the line on the sports field such that the generated audio signal is dependent on whether or not the sports gaming device bounces off the sports field where the surface modifications are applied. The detection system is configured to generate a sound profile from the audio signal sensed by the one or more audio sensors (102). The detection system is further configured to identify a bounce type based on the sound profile, wherein the bounce type is defined by whether or not the sports gaming device has bounced off the sports field where the surface modifications are applied.

Abstract: The invention relates to a method for logging an end terminal in a packet data network (AN), which supports the mobility of terminals. An address for the receipt of data packets is assigned to the terminal (UE) as follows: the terminal (UE) transmits an identification (IMSI) that has been allocated to it to the network (AN), via a mobile radio telephone communication system (PLMN) and the address (NI:IMSI) is then calculated according to a standard method by the terminal (UE) and by the network (AN, RAN), using the identification (IMSI).

Abstract: The invention relates to a radio access network (RAN) for a mobile radio communications system and to an operating method therefor. The radio access network has a number of first nodes (UPS1, UPS2,), which are each assigned to a subarea (A, a) of a geographical area, and which serve for exchanging useful data between terminals (UE), which are located in the relevant subarea, and a primary network (CN). The radio access network also has at least one second node (RCS1, RCS2), which comprises a number of signaling functionalities (UEF) for exchanging signaling data with the each respective terminal (UE). The second node (RCS1, RCS2, . . . ) is connected to a number of first nodes (UPS1, UPS2, . . . ) in order to exchange signaling data with a terminal (UE) via those first nodes (UPS1, UPS2, . . . ) with which this terminal (UE) exchanges useful data.

Abstract: The invention relates to a method according to which, in a speech-based service, a link is established between a user of said service and a speech service network server. According to the inventive method, the user of the service uses a short call number and a designation of the service to utilize said service. Using said short call number, the user establishes a link with the speech service network server and utilizes the designation of the service in the speech service network server to identify and start the service. The inventive system is particularly flexible when call numbers or services are changed, for the marketing of services and for the use of mnemonically obvious service designations.

Abstract: The invention relates to an access network for transmitting data packets between a network (NW) and a terminal (UE) via a radio communication system, and to a method for operating the same. The access network (AN) comprises a number of nodes (UPS) that are each linked with at least one radio station of the radio communication network and that are adapted to convert data stemming from the network (NW) to a format that is compatible with the transmission in the radio communication system. A permanent first address is defined for the terminal (UE). Data packets that are directed to the first address are forwarded to the address of a processor (VMH) allocated to the terminal (UE), said processor emulating the terminal (UE) in the access network and tracing its movement. The processor behaves towards the network (NW) as a mobile terminal that is compatible with a mobility protocol (Mobile IP, Cellular IP, IPv6).

Abstract: A mobile station communicates in a communication network formed of a core network and a radio access network with at least one first and one second radio network control device. The management of the mobile station or the transmission of data to be transmitted to the mobile station is handed over from the first radio network control device to the second radio network control device. To facilitate relocation, data that arrive after handover at the first radio network control device or that are temporarily stored there are transmitted to corresponding functionality of the second radio network control device using a functionality of the first radio network control device and are forwarded from the second radio network control device to the mobile station.
