For distributive services in telecommunications networks, and in particular methods for establishing point-to-multipoint connections and multipoint-to-point connections as well as methods of releasing these types of connections. Program distribution to several subscribers uses network resources in common along common call routes. A list of potential program distribution points is created and a running index is associated with each one of the distribution points. Before a connection is set up to a subscriber the list is examined and a distribution point is selected from which a point-to-point connection is set up to the subscriber. The running index is stepped up. The running index of a distribution point is stepped down during release of a connection and is examined with release of a call route section.

Point-to-multipoint connections

User terminals are connected to a telecommunication system. The telecommunication system includes a control system for the control, such as set-up, release and modification, of connections between the user terminals. A large portion of functions are common for control of dynamical as well as semi-permanent connections. Control of a connection can be initiated from any of the user terminals to which the connection relates, or from other user terminals. Control data for the connections can be stored in different types of storage resources in the control system, the different types of storage resources having different degrees of reliability.

Method of controlling connections in a telecommunication system

A method of dynamic resource allocation in a stratified network structure having a dynamically switched first stratum network and at least a second stratum network underlying the first overlying stratum network. At least a first route in the first stratum is provided with a first relation which points out two access points in the second stratum. A connection between the access points in the second stratum network is established and includes a second number of resources generally referred to as an infrastructure. The infrastructure is finally assigned to the first route.
