Abstract
The invention relates to a communication system and method wherein a user equipment contains, or is provided with, a list of items of service-related information. The list of service-related information represents a list of service provider names, services and/or service types or the like. When intending to establish or modify a session or connection or use a service, the user equipment selects, in one of the embodiments, an item from the list and performs a DNS query to resolve the name of the selected item to an IP address which then is used for set-up. The list may be provided by an DHCP server or in a PDP context message.The list may comprise one or more service provider default names, in particular for visited and home networks.
