Abstract
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+1)) 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+1)) 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.
