Method for allocating data-transmission resources, and corresponding switching method, access point, terminal, computer program and signal

A method comprising:

• switching data transmission from an initial transmission frequency channel to a destination transmission frequency channel, in a terminal associated with a multi-channel access point of a radiofrequency communications network, said multi-channel access point managing a set of at least two transmission frequency channels and being capable of simultaneously transmitting on said at least two frequency channels, wherein switching in the terminal comprises:
• a phase of associating and authenticating with said multi-channel access point, by said terminal, comprising a step of obtaining a unique identifier in said multi-channel access point, and
• a phase of managing the switching, by said terminal, implementing the following steps:
• determining a destination transmission frequency channel managed by said multi-channel access point, by processing at least one piece of information received from said multi-channel access point;
• and
• switching the data transmission from said initial transmission frequency channel to said determined destination transmission frequency channel, without modifying said identifier.

A multi-channel access point in a radiofrequency communications network, exchanging data with at least one terminal linked to the multi-channel access point, and managing a set of at least two transmission frequency channels, wherein the multi-channel access point comprises:

• a processor configured to perform steps of:
• implementing a phase of associating and authenticating a terminal with said multi-channel access point, comprising a step of associating, with said terminal, a unique identifier in said multi-channel access point, and
• implementing a phase of managing said set of transmission frequency channels, implementing a reference table associating with a terminal, identified by its unique identifier, one of said transmission frequency channels, said multi-channel access point being capable of simultaneously transmitting on said at least two frequency channels, the phase of managing comprising:
• detecting a switching of a terminal linked to said multi-channel access point, from a first transmission frequency channel, called an initial transmission frequency channel, to a second transmission frequency channel, called a destination transmission frequency channel;
• and
• updating said reference table to associate the unique identifier of said terminal with said destination transmission frequency channel.

A terminal of a radiofrequency communications network, comprising:

• a processor configured to perform steps of:
• linking with a multi-channel access point on a transmission frequency channel, called an initial transmission frequency channel, chosen from a set of at least two transmission frequency channels, managed by said multi-channel access point, which is capable of simultaneously transmitting on said at least two transmission frequency channels;
• implementing a phase of associating and authenticating with said multi-channel access point, comprising a step of obtaining a unique identifier in said multi-channel access point, and
• implementing a phase of managing the switching by:
• determining a destination transmission frequency channel managed by said multi-channel access point, by processing at least one piece of information received from said multi-channel access point;
• and
• switching the data transmission from said initial transmission frequency channel to said determined destination transmission frequency channel, without modifying said identifier.

A non-transitory computer readable memory comprising:

• a computer program stored thereon and comprising instructions for implementing a method for allocating data-transmission frequency resources in a radiofrequency communications network comprising at least one multi-channel access point exchanging data with at least one terminal linked to the multi-channel access point, said multi-channel access point managing a set of at least two transmission frequency channels, when this program is executed by a processor, wherein the instructions comprise:
• instructions configured to implement in said multi-channel access point a phase of associating and authenticating a terminal with said multi-channel access point, comprising a step of associating, with said terminal, a unique identifier in said multi-channel access point;
• and
• instructions configured to implement in said multi-channel access point a phase of managing said set of transmission frequency channels, implementing a reference table associating, with a terminal, identified by its unique identifier, one of said transmission frequency channels, said multi-channel access point being capable of simultaneously transmitting on said at least two frequency channels, and said phase of managing comprising the following steps:
• detecting a switching of a terminal linked to said multi-channel access point, from a first transmission frequency channel, called an initial transmission frequency channel, to a second transmission frequency channel, called a destination transmission frequency channel;
• and
• updating said reference table to associate the unique identifier of said terminal with said destination transmission frequency channel.
