More Information
Summary:As part of a localized positioning solution, a mobile device may transmit a request message to a server to obtain information about location contexts near the mobile device. In response, the server may, in some implementations, transmit a response message back to the mobile device that identifies a list of nearby LCIs and an area that encompasses these LCIs. The mobile device may store the returned LCI information and the returned area information in corresponding databases for later use. In some implementations, time limits may be placed on the returned area information after which the information is deemed stale. L'invention concerne une solution partielle de positionnement localisé dans laquelle un dispositif mobile peut transmettre un message de demande à un serveur pour obtenir des informations relatives à des contextes de localisation proches du dispositif mobile. En réponse, le serveur peut, dans certaines mises en oeuvre, renvoyer un message de réponse au dispositif mobile qui identifie une liste de LCI avoisinantes et une zone qui comprend ces LCI. Le dispositif mobile peut stocker les informations de LCI et les informations de zone renvoyées dans des bases de données correspondantes pour utilisation ultérieure. Dans certains modes de réalisation, des limites temporelles peuvent être placées sur les informations de zone renvoyées, les informations étant ensuite considérées comme périmées.
