Embodiment Construction

[0038] The invention relates generally to the positioning of mobile communication objects in a network.

[0039] As indicated in the introductory part, the present invention relates to any type of mobile communication objects, that is, communication terminals capable of exchanging data, such as mobile phones, portable computers, and personal digital assistants (i.e. APNs) and which can move between stations The logical entity of computing, as well as performing computing, mobile applications, logical or physical resources, and even users.

[0040] In the ensuing description, as an illustrative example, we consider mobile communication objects to be mobile terminals of the mobile phone type, which belong to, for example, a communication network of the WAN ("Wide Area Network" in English) type. Of course, the invention is not limited to this type of network. It also applies in particular to networks known as local area networks of the LAN ("Local Area Network" in English) type ...

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 nextrepeater (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 hasaddressed 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.

Description

technical field [0001] The invention relates to the field of communication networks, in particular to locating mobile communication objects in such networks. Background technique [0002] Here, "object" means anything capable of exchanging data, especially communication terminals such as mobile phones, portable computers, and personal digital assistants (i.e., APNs), as well as executing calculations, mobile applications, logical or Physical resources and even users. [0003] In a communication network, many mobile objects frequently move between domains (or stations), thereby changing addresses, or names, or namespaces. Two methods are generally used to contact or locate such moving objects. [0004] The first method consists in using a location server which keeps updated a location table storing the latest known location references (or location identifiers) of the mobile object. Thus, when a first mobile object called "source" wishes to communicate with a second mobile...
