Abstract: Data characterizing the presence state of a user registered to use a communication service is sent to a server for the management of presence data in order to provide presence data allocated to the user of a communication service. The data sent to the server is stored as presence data allocated to the user and is made available for predefinable first users. The user is provided with presence data allocated to predefinable second users. The predefinable first and second users are determined by means of an activated service profile allocated to the user.

Abstract: Quality of service is assured for connections routed via a plurality of subregions of a packet-oriented network via connection paths having prescribed transmission system resources by a resource manager in the packet-oriented network which has access to associated information relating to address ranges of the subregions, routes from source subregions to destination subregions through other subregions, and prescribed transmission system resources between the subregions. When a connection is initialized, a requested scope of resources and source and destination addresses are signaled to the resource manager, and a route through the network is ascertained. Then, taking into account the requested scope of resources and the scope of resources between the subregions of the route, a check is carried out to determine whether the initialized connection is authorized. In addition, the transmission system resources may be reserved for the initialized connection in the subregions included in the ascertained route.

Abstract: The invention relates to the control of transmission resources in individual transmission paths in a packet-oriented communication network, whereby data-packet address information (A1, A2) which identifies the origin and the goal of the data packets (DP1, DP2), is transmitted to a resource manager (RM), responsible for a transmission path (US), from a network transmission device (R1, R2). On a resource request (RA), for a connection to be subsequently generated, the origin and goal thereof are compared with the origin and goal of the previously transmitted data packets (DP1, DP2) by the resource manager (RM). Should there be agreement, the resource manager (RM) can deduce that the connection to be established can equally run over the corresponding transmission path (US). Correspondingly, establishment of further connections occurs, depending upon the available resources of said transmission path (US).

Abstract: A network access device checks communication data flows coming into a network for specific authorization information. The quality of service class (QOS) with which a flow is retransmitted from the network access device through the network is determined by the result of the check. Each end device that transmits a flow to the network access device can first request authorization for the flow from a gate keeper and resource manager mechanism of the network. The mechanism returns specific authorization information which the end device includes in the flow before the flow is transmitted to the network access device. In one embodiment, only if an incoming flow is determined to have the specific authorization information will the network access device allow the flow to be retransmitted through the network with a particular quality of service (QOS) class.

Abstract: The method is essentially carried out by a gateway device, which is logically divided up into a gateway controller and one or, if required, more user data gateways. Quality of service signaling is evaluated by the gateway controller and, depending thereon, quality of service information is transferred to a user data gateway. Specific quality of service properties of connection segments coming into and/or going out from the user data gateway are evaluated by the user data gateway and, depending thereon, a quality of service setting is carried out according to the transferred quality of service information.
