Abstract: The present invention relates to a portal structure providing end user stations (5) with access to services/applications (26), comprising a portal core (1) and a number of services/applications (26). The portal core comprises a presentation arrangement, portal session managing means (13) generating session related information, e.g. session identifications and portal storing means (51) for storing session related information. At least some of the services/applications (26) are external with external session identifications. Session unifying means (50) are provided for mapping between portal session identifications and external session identifications. For communication between the portal core (1) and external services/applications (26), the external identification is used, whereas, in communication between an end user station (5) and the portal core (1), only the portal session identification is used.

Abstract: The present invention relates to a portal structure supporting access by end user stations (6) using an access protocol for access requests containing basic information specifying group(s) or class(es) to which a requesting end user station (61) belongs, and type information specifying the type of the requesting end user station. The portal structure comprises a portal core and portal storing means (52) for storing at least type information for at least some type(s) of end user stations. It further comprises a device detection arrangement (53), and the portal storing means (52) supports storing of basic information such as class belongings of end user stations.

Abstract: The present invention relates to a portal structure for providing end user stations (5) with access to services/applications. It comprises a portal core (1) a connectivity layer via which end user station access is provided and a number of services/applications (25). The services/applications (25) are represented in a generic markup language and the portal core (1) uses said generic markup language for storing at least application/service data information and for communication with said services/applications. It further comprises a presentation arrangement (11) for communication with said applications/services (25) and said end user stations (5). Each service/aaplication (25) represented by generic data in the generic markup language may optionally be provided with a number of metalink tags, such that each service/application (25) is able to generate generic link data in the generic markup language irrespectively of the location of the portal structure and of other applications.
