Determining authentication credentials for a device-to-device service
There is provided an apparatus for a network node comprising means for receiving an indication of a serving network name of a first user equipment, the first user equipment configured to operate as a relay between a second user equipment and a network by providing a proximity-based service between the first user equipment and the second user equipment, means for determining an authentication vector for a proximity-based service authentication for the second user equipment based on the serving network name of the first user equipment; and means for providing an indication of the serving network name of the first user equipment to the second user equipment.
1 . An apparatus for a network node, comprising: at least one processor and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
receive an indication of a serving network name of a first user equipment, the first user equipment configured to operate as a relay between a second user equipment and a network by providing a proximity-based service between the first user equipment and the second user equipment;
determine an authentication vector for a proximity-based service authentication for the second user equipment based on the serving network name of the first user equipment; and
provide an indication of the serving network name of the first user equipment to the second user equipment.
2 . The apparatus according to claim 1 , further caused to:
provide authentication information to the second user equipment, wherein the authentication information comprises the indication of the serving network name of the first user equipment.
3 . The apparatus according to claim 2 , further caused to:
provide the authentication information in at least one of the following: a proximity-based service authentication response, a proximity-based service authentication request or an extensible authentication protocol message.
4 . The apparatus according to claim 1 , further caused to:
receive the serving network name of the first user equipment via at least one of the following: an access and mobility management function associated with the first user equipment or an authentication server function associated with the second user equipment.
5 . The apparatus according to claim 1 , wherein the network node implements a unified data management.
6 . A first user equipment, comprising: at least one processor and at least one memory storing instructions that, when executed by the at least one processor, cause the first user equipment at least to:
receive an indication of a serving network name of a second user equipment, the second user equipment configured to operate as a relay between the first user equipment and a network by providing a proximity-based service between the first user equipment and the second user equipment; and
determine an authentication vector for a proximity-based service authentication for the first user equipment based on the serving network name of the second user equipment.
7 . The first user equipment according to claim 6 , further caused to:
receive authentication information at the first user equipment, wherein the authentication information comprises the indication of the serving network name of the second user equipment.
8 . The first user equipment according to claim 7 , further caused to:
receive the authentication information in an extensible authentication protocol message.
9 . A method comprising:
receiving an indication of a serving network name of a first user equipment, the first user equipment configured to operate as a relay between a second user equipment and a network by providing a proximity-based service between the first user equipment and the second user equipment;
determining an authentication vector for a proximity-based service authentication for the second user equipment based on the serving network name of the first user equipment; and
providing an indication of the serving network name of the first user equipment to the second user equipment.
10 . The method of claim 9 , further comprising:
providing authentication information to the second user equipment, wherein the authentication information comprises the indication of the serving network name of the first user equipment.
11 . The method of claim 10 , further comprising:
providing the authentication information in at least one of the following: a proximity-based service authentication response, a proximity-based service authentication request or an extensible authentication protocol message.
12 . The method of claim 9 , further comprising:
receiving the serving network name of the first user equipment via at least one of the following: an access and mobility management function associated with the first user equipment or an authentication server function associated with the second user equipment.
13 . The method of claim 9 , wherein the network node implements a unified data management.
14 . A method comprising:
receiving an indication of a serving network name of a second user equipment, the second user equipment configured to operate as a relay between the first user equipment and a network by providing a proximity-based service between the first user equipment and the second user equipment; and
determining an authentication vector for a proximity-based service authentication for the first user equipment based on the serving network name of the second user equipment.
15 . The method of claim 14 , further comprising:
receiving authentication information at the first user equipment, wherein the authentication information comprises the indication of the serving network name of the second user equipment.
16 . The method of claim 15 , further comprising:
receiving the authentication information in an extensible authentication protocol message.
