e application keeps track of the user in which time zone (here e.g. roaming operator's home country or visitor location register (VLR) address) by having a dialogue with the user's home location register (HLR). When the trigger is released, it is morning time where the user is located. A request is sent to the VLR where the user is updated, to find out if he is active. If he is active a WAP session is set up using the MExE service capability server setting up the appropriate bearer, as defined in user data (terminal dependent).
