ABSTRACT:
A method in a system, a system, a method in a terminal and a terminal for service selection in a data network. The method sends, from a Wireless Local Area Network (WLAN) terminal, a Network Access Identifier (NAI) including a service selection indicator via a WLAN access point; receives, at an authentication server, the NAI including a service selection indicator, and provides the WLAN terminal with a connection to the service indicated by said selection indicator. The system comprises at least one WLAN access point and terminal comprising means for including a service selection indicator in a NAI and means for sending said NAI including said service selection indicator via the WLAN access point, at least one authentication server comprising means for receiving said NAI, means for extracting said service selection indicator from said NAI and means for initiating connection to a service indicated by said service selection indicator.
