Paging procedure for a wireless device, a radio access node, methods performed therein, a computer program, and a computer-readable storage medium

1. A method performed in a radio access node for handling a wireless device in a wireless communication network, which radio access node serves a cell in the wireless communication network, the method comprising:

receiving a paging request for the wireless device from a network node, which paging request comprises an indication, which indication indicates that the paging request is associated with a function relating to the wireless device, which function requires no connection between the wireless device and the radio access node to be set up, wherein the function is at least a status check of the wireless device and activation of the wireless device;

paging the wireless device in the cell with a page message, which the page message comprises an indication that the paging is associated with the function relating to the wireless device;

receiving a response from the wireless device in response to the page message, wherein the received response is a connection request;

rejecting a connection establishment or releasing a connection, from the wireless device to the radio access node, based on the indication in the received paging request and/or an indication in the received response indicating that no connection establishment is necessary;

transmitting a second response which informs the wireless device not to transmit another connection request; and

sending a third response to the network node when receiving the response from the wireless device, wherein the third response is sent simultaneously or after the rejecting of the connection or the releasing of the connection.

2. The method of claim 1 , wherein the received response is a Radio Resource Control message with an indication indicating that no connection establishment is necessary and the rejecting or the releasing is based on the indication in the Radio Resource Control message.

3. The method of claim 1 , wherein the function is localization of the wireless device.

4. The method of claim 1 , wherein the function requires no Radio Resource Control Connection and/or no Core network connection to be set up.

5. A computer program product comprising a non-transitory computer readable medium storing instructions which, when executed on at least one processor, cause the at least one processor to carry out the method of claim 1 .

6. A method performed in a wireless device for handling communication in a wireless communication network, which wireless communication network comprises a radio access node serving the wireless device in a cell of the radio access node, comprising:

receiving a message from the radio access node, which message comprises an indication that a paging is requested associated with a function relating to the wireless device, which function requires no connection between the wireless device and the radio access node to be set up, wherein the function is at least a status check of the wireless device and activation of the wireless device;

transmitting a response to the radio access node in response to the received message, which response comprises an indication indicating that no connection establishment is necessary, wherein the response is a connection request, wherein the transmitted response is a Radio Resource Control message; and

receiving a second response from the radio access node upon rejecting a connection establishment or releasing a connection, which second response informs the wireless device not to transmit another connection request;

wherein the radio access node is configured to send a third response to a network node when receiving the response from the wireless device, wherein the third response is sent simultaneously or after the rejecting of the connection or the releasing of the connection.

7. The method of claim 6 , wherein the received message is a page message or a random access message.

8. The method of claim 6 , wherein the function is localization of the wireless device.

9. The method of claim 6 , wherein the function requires no Radio Resource Control Connection and/or no Core network connection to be set up.

10. A computer program product comprising a non-transitory computer readable medium storing instructions which, when executed on at least one processor, cause the at least one processor to carry out the method of claim 6 .

11. A radio access node for handling a wireless device in a wireless communication network, which radio access node is configured to serve a cell in the wireless communication network, wherein the radio access node is further configured to:

receive a paging request for the wireless device from a network node, which paging request comprises an indication, which indication indicates that the paging request is associated with a function relating to the wireless device, which function requires no connection between the wireless device and the radio access node to be set up, wherein the function is at least a status check of the wireless device and activation of the wireless device;

page the wireless device in the cell with a page message, which the page message comprises an indication that the paging is associated with the function relating to the wireless device;

receive a response from the wireless device in response to the page message, wherein the received response is a connection request;

reject a connection establishment or release a connection, from the wireless device to the radio access node, based on the indication in the received paging request, and/or an indication in the received response indicating that no connection establishment is necessary; transmit a second response which informs the wireless device not to transmit another connection request; and

sending a third response to the network node when receiving the response from the wireless device, wherein the third response is sent simultaneously or after the rejecting of the connection or the releasing of the connection.

12. The radio access node of claim 11 , wherein the received response is a Radio Resource Control message with an indication indicating that no connection establishment is necessary and the radio access node is further configured to reject the connection establishment or release the connection based on the indication in the Radio Resource Control message.

13. The radio access node of claim 11 , wherein the function is: localization of the wireless device.

14. The radio access node of claim 11 , wherein the function requires no Radio Resource Control Connection and/or no Core network connection to be set up.

15. A wireless device for handling communication in a wireless communication network, wherein the wireless device is configured to be served by a radio access node in a cell of the radio access node in the wireless communication network, the wireless device being further configured to:

receive a message from the radio access node, which message comprises an indication that a paging is requested associated with a function relating to the wireless device, which function requires no connection between the wireless device and the radio access node to be set up, wherein the function is at least a status check of the wireless device and activation of the wireless device;

transmit a response to the radio access node in response to the received message, which response comprises an indication indicating that no connection establishment is necessary, wherein the received response is a connection request, wherein the response is a Radio Resource Control message; and to

receive a second response from the radio access node upon rejecting a connection establishment or releasing a connection, which second response informs the wireless device not to transmit another connection request;

wherein the radio access node is configured to send a third response to a network node when receiving the response from the wireless device, wherein the third response is sent simultaneously or after the rejecting of the connection or the releasing of the connection.

16. The wireless device of claim 15 , wherein the received message is a page message or a random access message.

17. The wireless device of claim 15 , wherein the function is localization of the wireless device.

18. The wireless device of claim 15 , wherein the function requires no Radio Resource Control Connection and/or no Core network connection to be set up.
