Method and a device for optimizing data transfer in a wireless communication network
First Claim
1. A data transmission device (600) comprising:
- a data interface (601) arranged to transmit and receive data, anda controller (602) connected to the data interface and arranged to run a routing protocol so as to enable the data transmission device to operate as a node of a wireless communication network,wherein the controller is further arranged to;
check, as a response to a situation in which routing information created or updated with the routing protocol indicates that data transfer from the data transmission device to a first other data transmission device is to be routed via at least one second other data transmission device, whether a direct radio link from the data transmission device to the first other data transmission device is possible, andcontrol, as a response to a situation in which the direct radio link is possible, the data transmission device to send a message which is addressed to the at least one second other data transmission device and which informs the at least one second other data transmission device that the data transfer from the data transmission device to the first other data transmission device is arranged to take place as direct radio communication from the data transmission device to the first other data transmission device.

Abstract
A method for optimizing data transfer in a wireless communication network is presented. A routing protocol is run for enabling data transmission devices (101-06) to form the wireless communication network. If routing information indicates that a route from a first data transmission device (101) to a second data transmission device (104) goes via at least one third data transmission (102, 103) device, it is checked whether a direct radio link (110) from the first data transmission device to the second data transmission device could be possible. If the direct radio link is possible, a message receivable by the at least one third data transmission device is sent. The message informs the third data transmission device that data transfer from the first data transmission device to the second data transmission device is direct radio communication and no forwarding actions are needed from the third data transmission device.

19. A method for optimizing data transfer in a wireless communication network, the method comprising carrying out the following actions in a data transmission device of the wireless communication network:
-
running (601), by the data transmission device, a routing protocol so as to enable a data transmission device to operate as a node of the wireless communication network, checking (603), by the data transmission device and as a response to a situation (602) in which routing information created or updated with the routing protocol indicates that data transfer from the data transmission device to a first other data transmission device is to be routed via at least one second other data transmission device, whether a direct radio link from the data transmission device to the first other data transmission device is possible, sending (605), by the data transmission device and as a response to a situation (604) in which the direct radio link is possible, a message which is addressed to the at least one second other data transmission device and which informs the at least one second other data transmission device that the data transfer from the data transmission device to the first other data transmission device is arranged to take place as direct radio communication from the data transmission device to the first other data transmission device, and using (606), by the data transmission device and as a response to the situation in which the direct radio link is possible, the direct radio link for the data transfer from the data transmission device to the first other data transmission device. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A non-transitory computer readable medium encoded with a computer program for optimizing data transfer in a wireless communication network, characterized in that the computer program comprises computer executable instructions for controlling a programmable processor of a data transmission device to:
-
check, as a response to a situation in which routing information created or updated with a routing protocol indicates that data transfer from the data transmission device to a first other data transmission device is to be routed via at least one second other data transmission device, whether a direct radio link from the data transmission device to the first other data transmission device is possible, and control, as a response to a situation in which the direct radio link is possible, the data transmission device to send a message which is addressed to the at least one second other data transmission device and which informs the at least one second other data transmission device that the data transfer from the data transmission device to the first other data transmission device is arranged to take place as direct radio communication from the data transmission device to the first other data transmission device.

36. A wireless communication network (100) comprising:
-
two or more first data transmission devices (101, 104) for wireless communication, and one or more second data transmission device (102, 103) for wireless communication, wherein each of the first data transmission devices and each of the second data transmission devices is arranged to run a routing protocol so as to enable the first data transmission devices and the one or more second data transmission devices to operate as nodes of the wireless communication network, wherein at least one of the first data transmission devices (101) is further arranged to; check, as a response to a situation in which routing information (131) created or updated with the routing protocol indicates that data transfer from this first data transmission device (101) to another of the first data transmission devices (104) is to be routed via at least one of the second data transmission devices (102, 103), whether a direct radio link (110) from this first data transmission device to the other first data transmission device is possible, send, as a response to a situation in which the direct radio link is possible, a message which is addressed to the at least one of the second data transmission devices and which informs the at least one second other data transmission device that the data transfer from this first data transmission device to the other first data transmission device is arranged to take place as direct radio communication from this first data transmission device to the other first data transmission device, and control, as a response to the situation in which the direct radio link is possible, this first data transmission device to use the direct radio link for the data transfer from this first data transmission device to the other first data transmission device. - View Dependent Claims (37, 38)
