Abstract: A communication terminal comprising: a radio interface and a WLAN communication module configured to: generate and send an association request; receive an association response; and establish IP connectivity. The communication terminal also comprises a service selection module configured to select a computer-implemented service to be accessed; and a service execution control module configured to execute software application code implementing the selected computer-implemented service.

Abstract: The invention provides a service distribution infrastructure comprising a plurality of tags and a data distribution server storing data elements in association with tag identifiers and application identifiers, the data distribution server being configured to receive a data distribution request from a requesting communication device, wherein the data distribution request comprises the tag identifier and an application module identifier, the data distribution server being configured to retrieve the data element associated with both the tag identifier and the application module identifier.

Abstract: Methods of and systems for establishing an augmented communication channel between an interactive voice response (IVR) system and an electronic device associated with a user are disclosed. A first method comprises sending, an audio call request; establishing an audio channel; establishing a data channel between the IVR system and the electronic device; receiving, via the data channel, IVR tree data, the IVR tree data allowing association of a position of the user with respect to the menu navigation structure; sending, via one of the audio channel and the data channel, a user selection relating to the IVR tree data; and receiving, via the other one of the audio channel and the data channel, an updated position of the user with respect to the menu navigation structure based on the user selection. A method to be executed by the IVR system is also disclosed.
