The invention relates to a mobile communicating object (A) belonging to a communications network and comprising processing means (PM). According to the invention, when a communication has been established with another communicating object (S) belonging to the network, the aforementioned processing means generate a repeater (Fi) at each site (Hi) through which they pass. Moreover, when the repeater is generated, the processing means associate a timing counter (CTF) therewith and configure said repeater such that: (i) it can store an identifier that is representative of the location of the next repeater (F(i+1)) or site (H(i+l)) in the chain of repeaters to which it belongs; and (ii) at the end of a selected duration of time, it transmits the location identifier of the next repeater (F(i+1)) or site (S(i+l)) to at least one location server (SL) in the network, so that it stores said identifier together with the primary identifier of the mobile object (A). Preferably, once a repeater has addressed the location identifier, the relay activity thereof is terminated and, if the repeater does not belong to another chain, it is removed so that it no longer consumes resources.

Un objet mobile communicant (A), d'un réseau de communications, comporte des moyens de traitement (PM) chargés, lorsqu'une communication a été établie avec un autre objet communicant (S) du réseau, de générer en chaque site (Hi) par lequel ils passent un répéteur (Fi) auquel ils associent, au moment de sa génération, un compteur temporel (CTF) et qu'ils configurent afin, d'une part, qu'il puisse stocker un identifiant représentatif de la localisation du répéteur (F(i+1)) ou site (H(i+l)) suivant dans la chaîne de répéteurs auquel il appartient, et d'autre part, qu'il transmette à au moins un serveur de localisation (SL) du réseau, à l'expiration d'une durée choisie, l'identifiant de localisation du répéteur (F(i+1)) ou site (S(i+l)) suivant pour qu'il le stocke en correspondance de l'identifiant primaire de l'objet mobile (A). Préférentielle~ment, une fois qu'un répéteur a adressé l'identifiant de localisation il cesse son activité de relai, puis s'il n'appartient pas à une autre chaîne il est supprimé afin de ne plus consommer de ressources.
