A radio paging system in which transmitting functions are given to terminals for radio paging so that the terminals can transmit the acknowledgment of paging signals and their own signals to a base station side as incoming signals through direct diffused-spectrum modulation, wherein the base station is capable of individually receiving incoming signals transmitted from the terminals as the acknowledgment signals and their own signals. Different diffused-spectrum codes are allocated to the incoming signals transmitted from the terminals as acknowledgment signals and their own signals.
L'invention concerne un système de recherche de personnes par radio dans lequel des fonctions de transmission sont données à des terminaux de recherche de personnes par radio, de manière que les terminaux puissent transmettre l'accusé de réception de signaux de recherche de personnes et leurs propres signaux à un côté station de base, sous la forme de signaux entrants, par une modulation directe du spectre diffusé, la station de base pouvant recevoir individuellement des signaux entrants transmis par les terminaux sous forme de signaux d'accusé de réception ainsi que leurs propres signaux. Différents codes de spectre diffusé sont attribués aux signaux entrants transmis par les terminaux en tant que signaux d'accusé de réception et leurs propres signaux.
