A method of enabling to mobile subscribers adjustable communication service parameters, such as lower charging rates, conditioned to a localised service area, and possibly in relation with a third party or institution. The subscriber receives an identifier (eg. a voucher or code) that he communicates to the operator, by means of e.g. an SMS, and triggers the desired activation, before or during the initiation of a communication. The mobile network indicates to the subscriber via the mobile terminal and by means of acoustic, visual or voice announcements before, during or at the end of the communication, different aspects related to the activation. This institution is related location, may be partly enabling and subsidising these communications, possibly by means of advertisements delivered to the subscriber. These parameters may remain enabled for a limited time, being dynamically revoked when the subscriber leaves the area, with the termination of ongoing communications, an appropriate explanatory acoustic/visual indication and voice message optionally taking then place. |
