The invention provides a method, an apparatus, and a computer program for supporting multiple connections to a network or a plurality of networks. Support for multiple connections is enabled by establishing a connection of a first type to a network, receiving a request for a connection of the first type, registering a virtual connection as a response to receiving said request, receiving a request for establishing a connection of a second type through the virtual connection, associating the virtual connection with the connection of the first type, and establishing the connection of the second type through the connection of the first type.

Multiple network connections

A vertical handover decision to perform a seamless vertical handover of a wireless apparatus from a current access network to a target access network is established. When deciding to perform the vertical handover from the current access network to the target access network it can be considered whether an intermediate access network could be used. It can be decided that first a seamless vertical handover is performed from the current access network to an intermediate access network, and subsequently a seamless vertical handover from the intermediate access network to the target access network is performed.

Vertical handover

A method and apparatus for authentication of data includes inputting of data into a first layer of a hashing function for rotation based hashing, then inputting results from the first layer to a second layer of the hashing function for substitution based hashing. Feedback is provided from the second layer to the first layer and digests are output from the first and second layers.

Method and apparatus for authentication of data using different hash functions and feedback

A system is provided for configuring an application for operation onboard a mobile node that includes a plurality of communication interfaces for accessing a plurality of types of networks. The system includes a network entity that can send a request for an application-specific profile for operating an application onboard the mobile node, the request including information identifying the application. In response, a profile server can create/retrieve an application-specific profile based upon the request. The application-specific profile includes one or more application-specific preferences and/or one or more application-specific settings, where at least one of the application-specific preference(s) and/or setting(s) can be interpreted into one or more policy rules capable of at least partially controlling selection of one or more of the communication interfaces of the mobile node during operation of the application. The application can thereafter be configured at least partially based upon the application-specific profile independent of user input.
