Methods, user equipment and application managing function node for managing transfer of message over radio interface

1. A method, performed by a user equipment (UE), for managing a message transferable over a radio interface of the UE, the method comprising:

receiving, from an application managing function, a configuration comprising a set of service identifiers mapped to a set of barring categories, wherein the set of service identifiers identifies at least one service;

receiving, from a radio access node, a set of barring parameters mapped to the set of barring categories, wherein each barring parameter indicates whether or not the radio interface is barred with respect to a respective barring category;

obtaining a service identifier associated with the message;

determining, based on the configuration, a barring category that is mapped to the service identifier;

determining a barring parameter that is mapped to the barring category; and

managing a transfer of the message over the radio interface according to the barring parameter.

2. The method of claim 1 , wherein the radio interface comprises at least one of:

a Uu interface between the UE and the radio access node, and

a PC5 interface between the UE and a further UE.

3. The method of claim 1 , wherein the transfer of the message relates to at least one of:

sending, by the UE, of the message,

receiving, by the UE, of the message, and

establishing a Packet Data Network, PDN, connection for the message.

4. The method of claim 1 , wherein said each barring parameter comprises a barring value indicating whether or not the radio interface is barred for the respective barring category.

5. The method of claim 1 , wherein said each barring parameter comprises at least one of: a barring factor and a barring duration.

6. The method of claim 1 , wherein said at least one service is related to at least one of:

Vehicle-to-everything; Public Safety communication; Public Safety discovery; wearable communication; multimedia telephony; IP Multimedia Subsystem; and Mobile Broadband.

7. The method of claim 1 , wherein the UE comprises a user application layer and a radio layer.

8. A method, performed by an application managing function, for facilitating management, by a user equipment (UE) of a message transferable over a radio interface of the UE, the method comprising:

obtaining a set of one or more service identifiers, wherein each service identifier included in the set of the service identifiers identifies at least one service; and

sending configuration information comprising the set of service identifiers and a set of barring category identifiers, wherein

each one of the barring category identifiers identifies a barring category, and

the configuration information links each service identifier included in the set of service identifiers to a single one of the barring category identifiers.

9. The method of claim 8 , wherein

the set of barring category identifiers includes a first barring category identifier and a second barring category identifier,

the first barring category identifier is mapped to a first barring factor for a first interface, and

the second barring category identifier is mapped to a second barring factor for the first interface.

10. The method of claim 9 , wherein

the first barring category identifier is mapped to a third barring factor for a second interface, and

the second barring category identifier is mapped to a fourth barring factor for the second interface.

11. The method of claim 10 , wherein

the first interface is a Uu interface, and

the second interface is a PC5 interface.

12. The method of claim 8 , wherein

the set of barring category identifiers comprises a first barring category identifier,

the method further comprises, after sending the configuration information, broadcasting barring parameter information, and

the barring parameter information a) comprises the first barring category identifier and a first barring factor and b) links the first barring factor to the barring category identifier.

13. The method of claim 12 , wherein

the set of barring category identifiers further comprises a second barring category identifier, and

the barring parameter information: a) further comprises the second barring category identifier and a second barring factor and b) links the first barring factor to the barring category identifier.

14. A user equipment (UE) for managing a message transferable over a radio interface of the UE, the UE comprising a processor configured to:

receive, from an application managing function, a configuration comprising a set of service identifiers mapped to a set of barring categories, wherein the set of service identifiers is configured to identify at least one service;

receive, from a radio access node, a set of barring parameters mapped to the set of barring categories, wherein each barring parameter is configured to indicate whether or not the radio interface is barred with respect to a respective barring category;

obtain a service identifier associated with the message;

determine, based on the configuration, a barring category that is mapped to the service identifier;

determine a barring parameter that is mapped to the barring category; and

manage a transfer of the message over the radio interface according to the barring parameter.

15. The UE of claim 14 , wherein the radio interface is configured to comprise at least one of:

a Uu interface between the UE and the radio access node, and

a PC5 interface between the UE and a further UE.

16. The UE of claim 14 , wherein the transfer of the message is configured to relate to at least one of:

sending, by the UE, of the message,

receiving, by the UE, of the message, and

establishing a Packet Data Network, PDN, connection for the message.

17. The UE of claim 15 , wherein said each barring parameter is configured to comprise a barring value indicating whether or not the radio interface is barred for the respective barring category.

18. The UE of claim 14 , wherein said each barring parameter is configured to comprise at least one of: a barring factor and a barring duration.

19. The UE of claim 14 , wherein said at least one service is configured to relate to at least one of:

Vehicle-to-everything; Public Safety communication; Public Safety discovery; wearable communication; multimedia telephony; IP Multimedia Subsystem; and Mobile Broadband.

20. The UE of claim 14 , wherein the UE is configured to comprise an application layer and a radio layer.
