Title: METHODS, DEVICES AND COMPUTER PROGRAMS FOR PROVIDING A SERVICE OR SERVICE COMPONENT REQUIRING A SPECIFIC PACKET-FORWARDING TREATMENT
Abstract:
In a method for providing, for a terminal device, a service or service component requiring a first packet-forwarding treatment, a network node (100) hosting a policy decision function determines (s10) that a dedicated bearer for carrying the traffic associated with the service or service component requiring the first packet- forwarding treatment cannot be used. This occurs when the service is initiated (s8a) or, in an alternative, for an ongoing service (s8b). The service or service component is then initiated or, in the alternative, maintained (s20), using a fallback bearer allowing the traffic associated with the service or service component to be carried with a second packet-forwarding treatment differing from the first one. The invention also relates to a method carried out, in such a context, by a network node (200) hosting an application function, and to computer programs, computer program products and storage mediums for carrying out such methods.
