determining requirements for data exchange under the mentioned conditions, when the first communication device does not have terrestrial network connection; determining, according to the conditions, a time interval within which the second communication device is expected to be located within Device-to-Device, D2D, communication range of the first communication device, wherein the time interval is a time interval when neither the first, nor the second communication device has terrestrial network connection; and executing, within the determined time interval, data exchange between the first and the second communication device, via a D2D communication. ### Claim 2 (depends on 1) The method according to claim 1, wherein the first communication device is listening to the satellite transmissions according to instructions, accessible to the first communication device. ### Claim 3 (depends on 1) The method according to claim 1, wherein the first communication device is listening to the satellite transmissions at predetermined time intervals. ### Claim 4 (depends on 1) The method according to claim 1, wherein the conditions, specify at least one of: when and how to set up D2D communication for the data exchange between the first and the second communication device; when and how to execute the data exchange between the first and the second communication device, and when and how to determine that an initiated data exchange is to be considered as at least partly completed. ### Claim 5 (depends on 1) The method according to claim 1, further comprising: receiving a verification of successful reception of at least part of the data exchanged between the first and the second communication device. ### Claim 6 (depends on 5) The method according to claim 5, wherein the verification is received from at least one of: the second communication device; the satellite, and a third communication device. ### Claim 7 (depends on 1) The method according to claim 1, wherein the determining of a time interval is executed dependent on the location of the first communication device, wherein the time interval is selected when the second communication device is expected to be within D2D communication range of the first communication device. ### Claim 8 A first communication device, capable of participating in a data exchange with a second communication device, the first communication device being configured to: recognize, from transmissions, transmitted from a satellite, conditions for allowing exchange of data between the first and the second communication devices; determine requirements for data exchange under the mentioned conditions, when the first communication device does not have terrestrial network connection; determine, according to the conditions, a time interval within which the second communication device is expected to be located within Device-to-Device, D2D, communication range of the first communication device, wherein the time interval is a time interval when neither the first, nor the second communication device has terrestrial network connection; and execute, within the determined time interval, data exchange between the first and the second communication device, via a D2D communication. ### Claim 9 (depends on 8) The first communication device, according to claim 8, wherein the first communication device is configured to listen to the satellite transmissions according to instructions, accessible to the first communication device. ### Claim 10 (depends on 8) The first communication device according to claim 8, wherein the first communication device is configured to listen to the satellite transmissions at predetermined time intervals. ### Claim 11 (depends on 8) The first communication device, according to claim 8, wherein the first communication device is configured to consider conditions, specifying at least one of: when and how to set up D2D communication for the data exchange between the first and the second communication device; when and how to execute the data exchange between the first and the second communication device, and when and how to determine that an initiated data exchange is to be considered as at least partly completed. ### Claim 12 (depends on 8) The first communication device, according to claim 8, wherein the first communication device is further configured to receive a verification of successful reception of at least part of the data exchanged between the first and the second communication device. ### Claim 13 (depends on 12) The first communication device, according to claim 12, wherein the first communication device is further configured to receive a verification from at least one of: the second communication device; the satellite, and a third communication device. ### Claim 14 (depends on 8) The first communication device, according to claim 8, wherein the first communication device is further configured to determine a time interval dependent on the location of the first communication device, wherein the time interval is selected when the second communication device is expected to be within D2D communication range with the first communication device.
