responsive to providing the at least one service via the wireless local area network access, accessing the wireless local area network access using a trusted wireless local area network access gateway that is part of the mobile network or under control of the mobile network.

2. The method according to claim 1 , wherein the network node is responsible for terminating a voice call to the user equipment and the at least one service is packet based voice communication.

3. The method according to claim 1 , wherein the information indicates whether packet based voice communication is supported for the wireless local area network access or the cellular network access to which the user equipment is attached.

4. The method according to claim 3 , wherein the at least one service is a voice call and the network node is configured with a policy to decide between terminating the voice call via the wireless local area network access and terminating the voice call via the cellular network access when terminating the voice call is supported by the wireless local area network access and by the cellular network access, the method further comprising:

terminating the voice call based on the policy.

5. The method according to claim 4 , wherein terminating the voice call based on the policy comprises terminating the voice call via the wireless local area network access.

6. The method according to claim 4 , wherein terminating the voice call based on the policy comprises terminating the voice call via the cellular network access.

7. A network node for a mobile network with at least one cellular network access and at least one wireless local area network access, the network node comprising:

an interface for interacting with a further network node; and

at least one processor;

wherein the at least one processor is configured to:

receive, from the further network node, information concerning a wireless local area network access to which a user equipment is attached;

receive, from the further network node, cellular network access information concerning a cellular network access to which the user equipment is attached; and

based on the information received and the cellular network access information received, control whether to provide at least one service provided to the user equipment via the wireless local area network access or via the cellular network access when the at least one service is available via the wireless local area network access and via the cellular network access; and

based on the information received and the cellular network access information received, control the at least one service provided to the user equipment based on whether to provide the at least one service via the wireless local area network access or via the cellular network access when the at least one service is available via the wireless local area network access and via the cellular network access,

responsive to providing the at least one service via the wireless local area network access, the at least one processor accesses the wireless local area network access using a trusted wireless local area network access gateway that is part of the mobile network or under control of the mobile network.

8. The network node according to claim 7 ,

wherein the network node is responsible for terminating a voice call to the user equipment and the at least one service is packet based voice communication.

9. The network node according to claim 7 ,

wherein the information indicates whether packet based voice communication is supported for the wireless local area network access or the cellular network access to which the user equipment is attached.

10. The network node according to claim 7 ,

wherein the at least one service is a voice call and wherein the network node is configured with a policy to decide between terminating the voice call via the wireless local area network access and terminating the voice call via the cellular network access when terminating the voice call is supported by the wireless local area network access and by the cellular network access; and

wherein the at least one processor is further configured to terminate the voice call based on the policy.

11. The network node according to claim 10 , wherein terminating the voice call based on the policy comprises terminating the voice call via the wireless local area network access.

12. The network node according to claim 10 , wherein terminating the voice call based on the policy comprises terminating the voice call via the cellular network access.

13. A computer program product for operating a network node comprising a non-transitory computer readable medium storing computer readable code, which when executed, causes at least one processor of the network node to perform operations comprising:

receiving, from a further network node, information concerning a wireless local area network access to which user equipment is attached;

receiving, by the network node from the further network node, cellular network access information concerning a cellular network access to which the user equipment is attached; and

based on the information received and the cellular network access information received, controlling, by the network node, whether to provide at least one service provided to the user equipment via the wireless local area network access or via the cellular network access when the at least one service is available via the wireless local area network access and via the cellular network access; and

based on the information received and the cellular network access information received, controlling, by the network node, the at least one service provided to the user equipment based on whether to provide the at least one service via the wireless local area network access or via the cellular network access when the at least one service is available via the wireless local area network access and via the cellular network access,

responsive to providing the at least one service via the wireless local area network access, accessing the wireless local area network access using a trusted wireless local area network access gateway that is part of the mobile network or under control of the mobile network.

14. The computer program product of claim 13 , wherein the information indicates whether packet based voice communication is supported for the wireless local area network access or the cellular network access to which the user equipment is attached.

15. The computer program product of claim 13 , wherein the at least one service is a voice call and the network node is configured with a policy to decide between terminating the voice call via the wireless local area network access and terminating the voice call via the cellular network access when terminating the voice call is supported by the wireless local area network access and by the cellular network access, wherein the operations further comprise terminating the voice call based on the policy.

16. The computer program product of claim 15 , wherein to terminate the voice call based on the policy, the operations further comprise terminating the voice call via the wireless local area network access.
