Abstract

Claims (29)

1. A radio access network (RAN) node comprising:

at least one processor; and

at least one memory including program code, the at least one memory and computer program code configured to, with the at least one processor, cause the RAN to perform:

receiving, by the RAN node, first radio capability information from a user equipment, the first radio capability information in a format of a first radio access technology;

generating, by the RAN node, second radio capability information of the user equipment based on the first radio capability information, wherein the second radio capability information is generated in a format of a second radio access technology; and

sending, by the RAN node to a core network node, the first radio capability information being in the format of the first radio access technology and the second radio capability information being in the format of the second radio access technology.

2. The RAN node according to claim 1 , wherein the core network node comprises a Mobility Management Entity or an Access and Mobility Management Function.

3. The RAN node according to claim 1 , wherein the RAN node comprises a source radio access node of the user equipment, the RAN node operating according to the first radio access technology.

4. The RAN node according to claim 1 , wherein the first radio access technology is one of a long term evolution access technology and a new radio access technology, and the second radio access technology is the other of the long term evolution access technology and the new radio access technology.

5. The RAN node according to claim 1 , wherein the at least one memory and computer program code are further configured to, with the at least one processor, cause the RAN node to perform:

receiving a radio capability identifier of the user equipment from the core network node, the radio capability identifier associated with both the first radio capability information and the second radio capability information.

6. A method comprising:

receiving, by a radio access network (RAN) node, first radio capability information from a user equipment, the first radio capability information being in a format of a first radio access technology;

generating, by the RAN node, second radio capability information of the user equipment based on the first radio capability information, wherein the second radio capability information is generated in a format of a second radio access technology; and

sending, by the RAN node to a core network node, the first radio capability information being in the format of the first radio access technology and the second radio capability information being in the format of the second radio access technology.

7. The method according to claim 6 , wherein the core network node comprises a Mobility Management Entity or an Access and Mobility Management Function.

8. The method according to claim 6 , wherein the RAN node comprises a source radio access node of the user equipment, the RAN node operating according to the first radio access technology.

9. The method according to claim 6 , wherein the first radio access technology is one of a long term evolution access technology and a new radio access technology, and the second radio access technology is the other of the long term evolution access technology and the new radio access technology.

10. The method according to claim 6 , further comprising:

receiving, by the RAN node a radio capability identifier of the user equipment from the core network node, the radio capability identifier associated with both the first radio capability information and the second radio capability information.

11. A non-transitory computer readable medium comprising program instructions for causing a radio access network (RAN) node to perform at least:

receiving, by the RAN node, first radio capability information from a user equipment, the first radio capability information in a format of a first radio access technology;

generating, by the RAN node, second radio capability information of the user equipment based on the first radio capability information, wherein the second radio capability information is generated in a format of a second radio access technology; and

sending, by the RAN node to a core network node, the first radio capability information being in the format of the first radio access technology and the second radio capability information being in the format of the second radio access technology.

12. The non-transitory computer readable medium according to claim 11 , wherein the core network node comprises a Mobility Management Entity or an Access and Mobility Management Function.

13. The non-transitory computer readable medium according to claim 11 , wherein the RAN node comprises a source radio access node of the user equipment, the RAN node operating according to the first radio access technology.

14. The non-transitory computer readable medium according to claim 11 , wherein the first radio access technology is one of a long term evolution access technology and a new radio access technology, and the second radio access technology is the other of the long term evolution access technology and the new radio access technology.

15. The non-transitory computer readable medium according to claim 11 , wherein non-transitory computer readable medium further comprises program instructions to perform:

receiving a radio capability identifier of the user equipment from the core network node, the radio capability identifier associated with both the first radio capability information and the second radio capability information.
