Prioritization method for radio access technologies used for wireless data communication

1. A method of controlling network access by a user equipment, the user equipment being adapted to communicate with an associated wireless network using a plurality of radio access technologies supported by the user equipment, the method comprising:

prioritizing, based on a mode of operation of the user equipment, at least one radio access technology from among the plurality of radio access technologies supported by the user equipment; and

transmitting uplink control signaling indicative of the prioritized at least one radio access technology to the associated wireless network.

2. The method of claim 1 , further comprising:

receiving downlink control signaling from the associated wireless network in response to transmitting the uplink control signaling,

wherein the down-link control signaling is indicative of whether the prioritized at least one radio access technology is accepted by the associated wireless network.

3. The method of claim 2 , further comprising:

performing data communication based on the prioritized at least one radio access technology and in accordance with the downlink control signaling.

4. The method of claim 1 , further comprising:

performing cell measurements in accordance with the received downlink control signaling.

5. The method of claim 4 , wherein the cell measurements are performed based on the prioritized at least one radio access technology, upon the prioritized at least one radio access technology being acknowledged.

6. The method of claim 4 , wherein the cell measurements are performed based on the plurality of radio access technologies supported by the user equipment, upon the prioritized at least one radio access technology not being acknowledged.

7. The method of claim 4 , further comprising:

receiving further downlink control signaling,

wherein the further downlink control signaling comprises override data, that induces an adaption of whether the cell measurements are performed based on the prioritized at least one radio access technology or based on the plurality of radio access technologies.

8. The method of claim 1 , wherein prioritizing the at least one radio access technology supported by the user equipment is based on at least one of:

an energy consumption;

the network access state comprising one of: an idle network access state, an inactive network access state or an active network access state;

a security level;

a geolocation;

a timing;

a service type; or

a quality of service.

9. The method of claim 8 , wherein the uplink control signaling is indicative of the at least one or more of the energy consumption, the network access state, the security level, the geolocation, the timing, the service type and/or the quality of service.

10. The method of claim 1 , wherein the uplink control signaling is included in one or more of a user equipment capability signaling; a user equipment uplink control signal; and/or a RRC configuration message.

11. The method of claim 1 , wherein the uplink control signaling comprises a list of at least one radio access technology that is not prioritized.

12. The method of claim 1 , wherein said prioritizing of the at least one radio access technology based on the network access state of the user equipment with the associated network is performed differently for at least two of a) an idle network access state, b) an inactive network access state and c) an active network access state of the user equipment.

13. A method for use in a network node of a wireless network connectable with an associated user equipment that is adapted to communicate with the wireless network using a plurality of radio access technologies supported by the associated user equipment, the method comprising:

receiving, from the associated user equipment, uplink control signaling indicative of at least one prioritized radio access technology prioritized from the plurality of radio access technologies supported by the associated user equipment based on a mode of operation of the associated user equipment; and

considering the at least one prioritized radio access technology when performing at least one network action associated with the associated user equipment.

14. The method of claim 13 , wherein the at least one network action comprises accepting or not accepting the prioritized at least one radio access technology.

15. The method of claim 14 , further comprising:

transmitting downlink control signaling to the associated user equipment in response to the uplink control signaling and indicative of whether the at least one prioritized radio access technology is accepted.

16. The method of claim 13 , wherein the at least one network action comprises instructing the associated user equipment to perform cell measurements based on the at least one prioritized radio access technology.

17. The method of claim 13 , wherein the at least one network action comprises allocating radio resources for communicating with the associated user equipment based on the at least one prioritized radio access technology.

18. The method of claim 13 , further comprising:

transmitting further downlink control signaling comprising override data, that induces an adaption of whether cell measurements are performed based on the prioritized at least one radio access technology or based on the plurality of radio access technologies.

19. The method of claim 13 , wherein the uplink control signaling is included in one or more of a user equipment capability signaling; a user equipment uplink control signal; and/or a RRC configuration message.

20. The method of claim 13 , wherein the uplink control signaling comprises a list of at least one radio access technology that is not prioritized.

21. The method of claim 13 , wherein the at least one network action comprises transmitting an inter-radio access technology handover command to a further network node.

22. The method of claim 1 , further comprising:

activating the prioritized at least one radio access technology in accordance with received downlink control signaling; and

deactivating one or more of the radio access technologies supported by the user equipment other than the prioritized at least one radio access technology in accordance with the received downlink control signaling,

wherein the transmitted uplink control signaling is indicative of the one or more of the radio access technologies supported by the user equipment other than the prioritized at least one radio access technology desired by the user equipment to be deactivated.

23. The method of claim 13 , wherein:

the receiving the uplink control signaling from the associated user equipment comprises receiving uplink control signaling indicative of one or more of the radio access technologies supported by the user equipment other than the prioritized at least one radio access technology desired by the user equipment to be deactivated; and

wherein the at least one network action comprises instructing the associated user equipment to:

activate the at least one prioritized radio access technology; and

deactivate the one or more of the radio access technologies supported by the user equipment other than the prioritized at least one radio access technology desired by the user equipment to be deactivated.

24. The method of claim 1 , wherein:

the prioritizing the at least one radio access technology comprises:

automatically prioritizing the user equipment from among the plurality of radio access technologies; and

the transmitting the uplink control signaling comprises:

automatically transmitting the uplink control signaling to the associated wireless network.
