Abstract

The invention relates to a method of creation of a new communication network by a wireless terminal. The wireless terminal is initially part of an existing centralized network that includes an access point able to control the association of wireless terminals to its network. In the event of disassociation of the terminal from the network, the method makes provision to initiate a procedure for creating a new network including a declaration of the terminal as access point of the new network, where the operating parameters of the new network are such that communications on the new network do not interfere with the existing network.

Claims

1. Method of creation of a new communication network by a wireless terminal, wherein the wireless terminal initially being part of an existing centralized network that includes an access point able to control the association of wireless terminals to its network, it includes, for the associated terminal, the steps of:

disassociation of the terminal from the network; and

initiation of a procedure for creating a new network including a declaration of the terminal as access point of the new network, where the operating parameters of the new network are such that communications on the new network do not interfere with the existing network.

2. Method according to claim 1, wherein the terminal initiates disassociation in at least one of the following cases:

frequency change rejection by the access point of the existing network following a request from the terminal in this sense;

or

connection establishment rejection by the access point of the existing network following a request from the terminal in this sense.

3. Method according to claim 1, wherein the access point of the existing network initiates the disassociation.

4. Wireless terminal including an interface with the communication medium, a microprocessor and a memory, which terminal is additionally includes in its memory a program comprising program means adapted to perform a disassociation of the terminal from the network and program means to perform an initiation of a procedure for creating a new network including a declaration of the terminal as access point of the new network, where the operating parameters of the new network are such that communications on the new network do not interfere with the existing network.

5. Wireless terminal according to claim 4, wherein the said program means are adapted to initiate the disassociation from the existing network in one of the following cases:

frequency change rejection by the access point of the existing network following a request from the terminal in this sense;

or

connection establishment rejection by the access point of the existing network following a request from the terminal in this sense.
