A simplified evaluation of messages that control connection setup is made possible by a method for filtering () incoming messages () at a connection controlling element () of a telecommunications network () on the basis of predetermined filtering conditions (). According to this method, the filtering () ensues by comparing () text elements (to) in a received () message () with text elements (to) in a document (), which can be accessed () by the connection controlling element () and which contains the filtering conditions in the form of text elements (to), and by verifying () whether, inside the document (), logical links (to) of filtering conditions (to) apply to the message (), said logical links being specified in an internet page description method (XML).

The invention relates to a method for running communication services or a corresponding service logic in a communication system (UMTS), whereby a station (A, B) logs on to an access device (PA or PB) of the communication system (UMTS), and service-related instructions depending on a service logic relating to the station (A or B) are emitted on the network side, in a network device on the connection path between the station (A, B) and another station (B or A). The aim of the invention is to enable the service logic to be updated without having to transmit it from the station with, for example, registration data each time. To this end, the service logic relating to said station (A or B) is called by the device (PA or PB) emitting the instruction, from a service data bank (DD) in which the service logic is stored on the network side.
