CA 2214716

Information services on demand by user allows a user in a one-way communication paging system to obtain on a limited basis information service items without interacting directly with the paging system to demand transmission thereof. The system provides information services in separate transmission channels. In each transmission channel including information service items, indicia thereinindicates categories of information items available therein. A remote information terminal (106), in response to user demand for a given category of information service (306), seeks information service items in that category by monitoring transmission channels and comparing information service indicia therein to the demanded information service. The user need not interact directly with the paging system to obtain information service items on a limited basis.

Les services d'information sur demande de l'utilisateur décrits permettent à un utilisateur, par un système de radiomessagerie unidirectionnelle, d'obtenir dans certaines limites certains services d'information sans interagir directement avec le système de radiomessagerie pour demander la transmission du service. Le système fournit des services d'information par des canaux de transmission séparés. Chaque canal de transmission supportant des services d'information comporte des repères indiquant les catégories d'information disponibles par le canal. Un terminal d'information à distance (106), en réponse à une demande de l'utilisateur relative à une catégorie donnée de service d'information (306), recherche des informations dans cette catégorie en explorant les canaux de transmission et en comparant les repères de service d'information qui s'y trouvent au service d'information demandé. L'utilisateur n'a pas besoin d'interagir directement avec la radiomessagerie pour obtenir des services d'information dans certaines limites.
