Method for power efficient data transmission
Provided is a method for data transmission from a user equipment to a remote server by means of a base station of a cellular network, wherein the user equipment is configured to carry out payload data transmission to said remote server. It comprises: carrying out a first signaling data transmission to the base station, determining a first power value representative of the power spent for said first signaling data transmission, maintaining the first power value as reference value, carrying out a second signaling data transmission to the base station, and determining a second power value representative of the power spent for said second signaling data transmission. In case said second power value exceeds said first power value by a predetermined threshold value, it delays the next payload data transmission for a predetermined time.

carrying out a second signaling data transmission (TAU 2 ) to the base station,
determining a second power value (PV 2 ) representative of the power spent for said second signaling data transmission (TAU 2 ), and
when said second power value (PV 2 ) exceeds said reference power value by a predetermined threshold value, delaying the payload data transmission (DP 1 ) for a predetermined time.
2. The method according to claim 1 , further comprising,

deactivating said power saving mode before the step of carrying out the second signaling data transmission (TAU 2 ).
3. The method according to claim 2 , wherein the delay for the payload data transmission (DP 1 ) lasts at least after conducting a third signaling data transmission (TAU 3 ) to the base station.
4. The method according to claim 2 ,

5. The method according to claim 4 ,
further comprising the step of amending the predetermined threshold value considering at least one out of the group:
carrying out said payload data transmission (DP 1 ),
delaying said payload data transmission (DP 1 ).
6. The method according to claim 5 , further comprising the step of amending the reference value considering at least two determined power values indicative of the power spend for said signaling data transmission.
7. The method according to claim 4 , wherein the user equipment is further maintaining a maximum delay tolerance value, wherein the method comprises the step of carrying out the payload data transmission (DP 1 ) in case the expired delay exceeds the maximum delay tolerance value.
8. The method according to claim 7 ,
further comprising the step of amending at least one out of the group of:
the delay tolerance value,
the predetermined threshold value, and
power saving mode duration,
when the payload data transmission (DP 1 ) is carried out due to exceeding the maximum delay tolerance.
9. A user equipment for data transmission to a remote server by means of a base station of a cellular network, wherein the user equipment is configured to regularly carrying out payload data transmission (DP 1 ) to said remote server, further configured to:
carry out a first signaling data transmission (TAU 1 ) to the base station,
determine a first power value (PV 1 ) representative of the power spent for said first signaling data transmission (TAU 1 ),
maintaining the first power value (PV 1 ) as reference power value,
carry out a second signaling data transmission (TAU 2 ) to the base station,
determine a second power value (PV 2 ) representative of the power spent for said second signaling data transmission (TAU 2 ),
when said second power value (PV 2 ) exceeds said reference power value by a predetermined threshold value, delay the payload data transmission (DP 1 ) for a predetermined time.
10. The user equipment according to claim 9 , further configured to:
activate, after the step of determining a first power value (PV 1 ), a power saving mode at the user equipment, and
deactivate said power saving mode before the step of carrying out the second signaling data transmission (TAU 2 ).
11. The user equipment according to claim 9 , further configured that the delay for the payload data transmission (DP 1 ) lasts at least after conducting a third signaling data transmission (TAU 3 ) to the base station.
12. The user equipment according to claim 11 ,
further configured to amend the predetermined threshold value considering at least one out of the group:
carrying out said payload data transmission (DP 1 ),
delaying said payload data transmission (DP 1 ).
13. The user equipment according to claim 12 ,
further configured to amend the reference power value considering at least two determined values indicative of the power spend for said signalling data transmission.
14. The user equipment according to claim 13 , further configured to maintain a maximum delay tolerance value, and to carry out the payload data transmission (DP 1 ) in case the expired delay exceeds the maximum delay tolerance value.
15. The user equipment according to claim 14 ,

the delay tolerance value,
the predetermined threshold value, and
power saving mode duration,
