Abstract

The invention pertains to the field of reservation methods for communication within a mobile communication network. It is a reservation method for communication within a mobile communication network (10) comprising access points for accessing the mobile communication network and mobile terminals intended to be connected to the access points. For a mobile terminal (40) intended to follow a predetermined route including a list of fixed access points, the resources needed to maintain a minimum quality of service threshold during a communication of said mobile terminal when said mobile terminal changes connection from one of said fixed access points to another one of said fixed access points are firmly reserved beforehand from multiple successive fixed access points on said list.

Claims

1. A reservation method for communication within a mobile communication network (10) comprising access points for accessing the mobile communication network and mobile terminals intended to be connected to the access points, characterized in that for a mobile terminal (40) intended to follow a predetermined route including a list of fixed access points, the resources needed to maintain a minimum quality of service threshold during a communication of said mobile terminal when said mobile terminal changes connection from one of said fixed access points to another one of said fixed access points are firmly reserved beforehand from multiple successive fixed access points on said list.

2. A reservation method for communication according to claim 1, characterized in that the reservation step reserves the resource beforehand from multiple successive access points on said list respectively during time windows (7, 8) that are successively spread apart in time.

3. A reservation method for communication according to claim 1, characterized in that the reservation step is not preceded by a step of measuring quality of service.

4. A reservation method for communication according to claim 1, characterized in that the communication of said mobile terminal corresponds to the running of an application within an Internet core network (20) connected to said mobile terminal via said mobile communication network.

5. A reservation method for communication according to claim 4, characterized in that said application is a real-time application.

6. A reservation method for communication according to claim 1, characterized in that the reservation method for communication comprises a step of locating the mobile terminal, making it possible to first detect a travel incident and then to cancel all or some of the resource reservation and/or to temporally shift some of the resource reservation.

7. A reservation method for communication according to claim 1, characterized in that the reservation step is preceded by a step of determining a list of fixed access points located along a predetermined route of a mobile terminal.

8. A system comprising:

a mobile communication network (10) comprising access points for accessing the mobile communication network and mobile terminals intended to be connected to the access points;

an Internet core network (20);

an application network (30) comprising means (31, 32, 33, 34, 35) capable both of determining a list of fixed access points (11, 12) located along a predetermined route of a mobile terminal (40) and of firmly reserving the resource beforehand from multiple successive fixed access points on said list, in such a way as to permanently guarantee said mobile terminal a minimum quality of service during a communication of said mobile terminal when said mobile terminal changes connection from one (11) of said fixed access points to another one (12) of said fixed access points.

9. An application server (31) for a mobile communication network comprising access points for accessing the mobile communication network (10) and mobile terminals intended to be connected to said access points, said server being capable of firmly reserving the resource beforehand, based on a list of fixed access points (11, 12) located along a predetermined route of a mobile terminal, from multiple fixed successive access points on said list, in such a way as to permanently guarantee said mobile terminal a minimum quality of service during a communication of said mobile terminal when said mobile terminal changes connection from one (11) of said fixed access points to another one (12) of said fixed access points.
