Claim 9

A method for allocation of switching-oriented resources in a communication system operating in asynchronous transfer mode and having communication terminal equipment connected thereto, comprising the steps of: providing at least a number of switching-oriented resources; logging-on the number of switching-oriented resources provided for communication of digital information by a communication terminal equipment whose digital information packeted in cells is to be communicated via the communication system without cell losses, said number of switching-oriented resources being reported within a framework of a call signaling by, up to reception of a first cell, logon information and by number of resources information; providing two resource administration areas in routing tables of the communication system with whose assistance switching-oriented routing information, the logon information and the number of resources information are respectively entered in call-associated fashion, resources availability information and resources use information being one of entered and not entered into said two resource administration areas with the assistance of the communication system, said resources availability information indicating the availability of logged on number of resources in the communication system dependent on the traffic load; given reception of a first cell to be communicated free of cell losses in the communication system, discarding the first cell and all further cells dependent on insertion of resources availability information to thereby cause only a short chronological delay or switching cells loss-free with the assistance of the logged on number of switching-oriented resources, and, given a switching of the cells, entering resources use information into an allocated resources administration area, as a consequence whereof the logged on number of resources is exclusively allocated to the respective call for the communication of the cells to be communicated free of cell losses; and indicating release of the allocated number of resources upon reception of a last cell to be communicated free of cell losses by removal of the resources use information.

Claim 14

A method for allocation of switching-oriented resources in a communication system operating in asynchronous transfer mode and having communication terminal equipment connected thereto, comprising the steps of: providing at least a number of switching-oriented resources; logging-on the number of switching-oriented resources provided for communication of digital information by a communication terminal equipment whose digital information packeted in cells is to be communicated via the communication system without cell losses, said number of switching-oriented resources being reported within a framework of a call signaling, up to reception of a first cell, by logon information and by number of resources information; providing two resource administration areas in routing tables of the communication system with whose assistance switching-oriented routing information, the logon information and the number of resources information are respectively entered in call-associated fashion, resources availability information and resources use information being one of entered and not entered into said two resource administration areas with the assistance of the communication system, said resources availability information indicating the availability of logged on number of resources in the communication system dependent on the traffic load; given reception of a first cell to be communicated free of cell losses in the communication system, discarding the first cell and all further cells dependent on insertion of resources availability information to thereby cause only a short chronological delay or switching cells loss-free with the assistance of the logged on number of switching-oriented resources, and, given a switching of the cells, entering resources use information into an allocated resources administration area, as a consequence whereof the logged on number of resources is exclusively allocated to the respective call for the communication of the cells to be communicated free of cell losses; indicating release of the allocated number of resources upon reception of a last cell to be communicated free of cell losses by removal of the resources use information; and allocating the logged on number of resources for switching of incoming cells to be communicated in a further call until reception of the first cell to be communicated free of cell losses, and completely discarding the incoming first and further cells to be communicated free of losses.
