<p>A primary node (120) of a mobile communication network (100) receives an incoming source data message (msg<SUB>s</SUB>) that is originated by a source station (MSA) and directed to a terminating station (MSB). A location node (130) is associated with a database storing information, which for each subscriber (MSB) in the network (100) defines a target node (160) currently responsible delivering data messages (msg<SUB>s</SUB>; msg<SUB>MOD</SUB>) wirelessly to terminating stations (MSB) located within a defined service area. A service filtering node (140) is adapted to investigate whether or not the terminating station (MSB) subscribes to a message transformation service, and if so the source data message (msg<SUB>s</SUB>) is forwarded to a message modifying node (150). This node (150), in turn, is adapted to produce a modified data message (msg<SUB>M0D</SUB>) including the source data message (msg<SUB>s</SUB>) and at least one added data segment (msg<SUB>ADD</SUB>), e.g. representing an advertisement. Thereafter, the message modifying node (150) forwards the modified data message (msg<SUB>MOD</SUB>) to the target node (160) which according to the location node (130) is responsible for delivering data messages to the terminating station (MSB).</p> |
