A telecommunications services apparatus, to be used with a mobile telephone system such as one capable of handling short message service (SMS) text messages, is operable to provide information upon request from users of mobile stations (1). A communications processor (10) receives an SMS data request from a mobile station (1) via the mobile switching centre (5), and then returns requested data to the mobile station (1) via the mobile system. A data store (22,28) stores information in a hierarchical structure. An information processor (12) can retrieve information from the data store (22,28) in accordance with received query data, the information processor (12) having a query store (16) associated with the CLI of the mobile station (1). The query store (16) holds an indication of the relative position in the hierarchical structure of the information retrieved in response to a previous query from the mobile station (1). <IMAGE> |
