Abrégé

A method is disclosed comprising: obtaining route request information characterizing a route to be provided to a terminal; determining, at least partially based on the route request information, an intermediate route comprising a plurality of link identifiers respectively identifying links in respective current versions of one or more map regions; determining a final route by replacing, in the intermediate route, one or more link identifiers by respective indications, wherein each indication of the indications respectively indicates whether or not a link or considered-to-be- suited link corresponding to a link, which is identified by the link identifier replaced by the indication and which is contained in a current version of a map region, is considered to be contained in a non-current-version of the map region available to the terminal, wherein the considered-to-be-suited-link is a link that is considered to be suited to be used for a route guiding process at the terminal; and outputting the final route. Further disclosed are a corresponding apparatus, a corresponding system and a corresponding computer program.

Abrégé

A method is disclosed comprising: obtaining, at a terminal, a final route that comprises one or more indications, wherein each indication of the indications respectively indicates, whether or not a link or considered-to-be-suited link corresponding to a link that is contained in a current version of a map region and is identified by a respective link identifier comprised in an intermediate route determined at least based on respective current versions of one or more map regions and used as a basis for determining the final route, is considered to be contained in a non-current version of the map region available to the terminal; and conducting a route guiding process at the terminal at least based on the final route and at least respective non- current versions of one or more map regions available to the terminal that respectively contain, according to the one or more indications, a link or considered-to-be-suited link corresponding to a link that is contained in a respective current version of the respective map region and is identified by a respective link identifier comprised in the intermediate route, wherein the considered-to-be-suited link is a link that is considered to be suited to be used for the route guiding process at the terminal. Further disclosed are a corresponding apparatus, a corresponding system and a corresponding computer program.
