The invention relates to a system and a process for enabling location queries for mobile networks which allows considering the dimensions of time, area, probability and relative distance between users, for enabling queries by services and applications which use or benefit from these dimensions. The proposed system and process is superimposed on any location system existing in mobile networks (1) and allows aiding it with specific functions present in the mobile terminal which, for example, inform on other nearby mobile terminals detected by means of short-range radio technologies, inform on the change of cell by the mobile terminal when such terminal is in inactive mode or informs on the absolute location available by means independent of the mobile network (2, 2'). The invention includes: functions of collecting, calculating, filtering and storing raw information on absolute and relative location between users (3, 4); functions of aggregating, calculating, filtering and storing post-processing material from the foregoing (5, 6); and an interface or gateway (8), together with the necessary auxiliary calculation functions (7), for enabling queries by services and applications (9, 9', 9"), from the information contained in both storage functions.
