Method for associating an apparatus in a communication network
View Patent ↗The subject of the invention is a process for associating an apparatus to a first communication network, the transmissions in the first network being performed on a first channel. The process comprises: detection by said apparatus of the first transmission channel; determination of collision on said channel between signals originating from the first network and from a second network; in case of collision, transmission of a change of channel request to the first network. The invention applies in particular within the framework of local networks such as HIPERLAN 2.
1. A process for associating an apparatus to a first communication network, with transmissions in the first network being performed on a first channel, wherein the process comprises, the steps of:
(A) detection by said apparatus of the first transmission channel;
(B) determination of a collision on said channel between signals originating from the first network and from a second network;
(C) when said collision has been determined, transmitting a change of channel request to the first network, and
(D) associating the apparatus with a base station of the first network, following non-detection of collision.
2. A process for associating an apparatus to a first communication network, with transmissions in the first network being performed on a first channel, wherein the process comprises, the steps of:
(A) detection by said apparatus of the first transmission channel;
(B) determination of a collision on said channel between signals originating from the first network and from a second network;
(C) when said collision has been determined, transmitting a change of channel request to the first network, wherein the preceding steps are repeated until the first network locks onto a channel for which no collision has been detected.
3. A process for associating an apparatus to a first communication network, with transmissions in the first network being performed on a first channel, wherein the process comprises, the steps of:
(A) detection by said apparatus of the first transmission channel;
(B) determination of a collision on said channel between signals originating from the first network and from a second network;
(C) when said collision has been determined, transmitting a change of channel request to the first network, wherein the change of channel request comprises an identifier of the first network.
4. A process for associating an apparatus to a first communication network, with transmissions in the first network being performed on a first channel, wherein the process comprises, the steps of:
(A) detection by said apparatus of the first transmission channel;
(B) determination of a collision on said channel between signals originating from the first network and from a second network;
(C) when said collision has been determined, transmitting a change of channel request to the first network, wherein the change of channel request comprises an identifier of the apparatus.
5. A process for associating an apparatus to a first communication network, with transmissions in the first network being performed on a first channel, wherein the process comprises, the steps of:
(A) detection by said apparatus of the first transmission channel;
(B) determination of a collision on said channel between signals originating from the first network and from a second network;
(C) when said collision has been determined, transmitting a change of channel request to the first network, wherein the request comprises a parameter indicating a transmission channel suggested to the first network.
6. A process for associating an apparatus to a first communication network, with transmissions in the first network being performed on a first channel, wherein the process comprises, the steps of:
(A) detection by said apparatus of the first transmission channel;
(B) determination of a collision on said channel between signals originating from the first network and from a second network;
(C) when said collision has determined, transmitting a change of channel request to the first network, wherein the request comprises a parameter indicating the number of times that the request has already been sent to the first network.
7. A process for associating an apparatus to a first communication network, with transmissions in the first network being performed on a first channel, wherein the process comprises, the steps of:
(A) detection by said apparatus of the first transmission channel;
(B) determination of a collision on said channel between signals originating from the first network and from a second network;
(C) when said collision has been determined, transmitting a change of channel request to the first network, wherein before association is made from the apparatus to the first network, the apparatus knows the identity of a central controller of the first network and in that the frames transmitted on this first network comprise a field identifying the central controller.
8. The process as claimed in claim 7 , wherein the determination of the collision is carried out by detecting the fact that the apparatus cannot decode at least one of:
certain frames transmitted on the first network and parts of frames transmitted on the first network.
