Abstract: The invention relates to a method for storing and passing on multimedia messages for a multimedia call in a packet-switching telecommunication network (TN), with the called subscriber (B subscriber) having network access with a known and predetermined bandwidth to the telecommunication network (TN). In the situation where it is found (1) during the setting up of a multimedia call that the available bandwidth is too narrow (2, 3) because the called subscriber (B subscriber) is currently using a further multimedia service, the multimedia call is diverted (4) to a recording device (ABZ) which is available in the telecommunication network (TN). A calling subscriber (A subscriber) can then leave a multimedia message on the recording device (ABZ), which is then passed (5) to a local recording device (ABL) for the called subscriber (B subscriber) via the network access and using the bandwidth that is still available.

Abstract: The invention relates to a method and device for managing at least one capability characteristic (F1, F2, F3), which is subject to license or for managing at least one group (G1, G2, G3) of capability characteristics (F1, F2, F3), which are subject to license, of a switching system of a telecommunications network. According to the invention, at least one use counter (C, E1, E2) at a time is assigned to the at least one capability characteristic (F1, F2, F3) and/or to the at least one group (G1, G2, G3) of capability characteristics (F1, F2, F3). Said use counter indicates the current number of uses of the capability characteristic (F1, F2, F3) or of the group (G1, G2, G3) of capability characteristics (F1, F2, F3). A typical use of the invention involves the sharing of a switching system by an number of service providers.

Abstract: The invention relates to an exchange for connecting telecommunications terminals of subscribers to a telecommunications network, comprising subscriber lines via which the respective telecommunications terminals are linked with the exchange. Said exchange is operated by a first network operator and is used by further network operators. The subscriber lines and subscribers are associated with one of said network operators each and the subscribers select the exchange via the telecommunications terminals to establish a telecommunications link via the respective network operator. The invention further relates to a method for operating an exchange that is used in the inventive exchange.

Abstract: At least one part of at least two user connections (TA1 . . . 6) having configured performance criteria and being allocated to at least two network devices (LE1 . . . 3) is assigned to at least one group (NWHG), to which group-specific performance criteria and/or characteristics (PDN, HUNT) can be allocated. The group (NWHG) is controlled by one of the network devices (LE1), whereby the user connections (TA1, 3, 4, 6) which have not been physically allocated to this network device (LE1) are allocated to said device as virtual user connections.

Abstract: Data management systems of real-time systems are intended to provide user systems with rapid and consistent on-line management of various data generations. This is achieved by an access data structure which allows a generations management system (GMS) to carry out the management of various data generations on the basis of the same data objects already used on a previous occasion by a transaction management system (TMS) for carrying out transactions.
