Abstract: front page image
(EN)An Aided Location Communication System ('ALCS') is described that may include a geolocation server and a wireless communication device having a GPS section where the GPS receiver section is capable of being selectively switched between a standalone mode and at least one other mode for determining a geolocation of the wireless communications device. An Aided Location Communication Device ('ALCD') is also described. The ALCD includes a position-determination section having a GPS receiver and a communication section where the position-determination section is selectively switchable between a GPS-standalone mode and at least one other mode for determining a geolocation of the ALCD.
(FR)La présente invention concerne un système de communication d’emplacement assisté (« ALCS ») qui peut comprendre un serveur de géolocalisation et un dispositif de communication sans fil comprenant une section GPS où la section du récepteur GPS peut être sélectivement basculée entre un mode indépendant et au moins un autre mode pour déterminer la géolocalisation du dispositif de communications sans fil. Il comprend aussi un dispositif de communication d’emplacement assisté ('ALCD'). Ce dispositif comprend une portion de détermination d’emplacement comprenant un récepteur GPS et une portion de communication où la première portion est sélectivement basculable entre un mode GPS indépendant et au moins un autre mode pour déterminer une géolocalisation de l’ALCD.
