A method of retrieving location information for a user equipment, UE, connected to a managed access network, the method being performed in an Evolved Packet Data Gateway, ePDG, the method comprising: upon completion of: the UE attaching to an access point of the managed access network including obtaining an outer IP address from a Dynamic Host Control Protocol, DHCP, server, the IP address being part of an address space owned by the managed access network; establishing an IP tunnel between the ePDG and the UE over the managed access network, wherein the IP tunnel uses addresses from the address space owned by the managed access network for outer headers of traffic sent via the tunnel; the UE registering with a service network via the IP tunnel, including obtaining an inner IP address from an address space of the service network; performing the steps of: receiving a request for location information for the UE from a Packet Delivery Network Gateway, PDN-GW or authentication, authorisation and accounting, AAA, server; sending a request for location information for the UE to the DHCP server of the managed access network, the request for location information comprising the outer IP address of the UE; receiving a response containing location information for the UE from the DHCP server; sending a response containing the location information for the UE to the PDN-GW or AAA server. upon completion of: the UE attaching to an access point of the managed access network including obtaining an outer IP address from a Dynamic Host Control Protocol, DHCP, server, the IP address being part of an address space owned by the managed access network; establishing an IP tunnel between the ePDG and the UE over the managed access network, wherein the IP tunnel uses addresses from the address space owned by the managed access network for outer headers of traffic sent via the tunnel; the UE registering with a service network via the IP tunnel, including obtaining an inner IP address from an address space of the service network; the UE attaching to an access point of the managed access network including obtaining an outer IP address from a Dynamic Host Control Protocol, DHCP, server, the IP address being part of an address space owned by the managed access network; establishing an IP tunnel between the ePDG and the UE over the managed access network, wherein the IP tunnel uses addresses from the address space owned by the managed access network for outer headers of traffic sent via the tunnel; the UE registering with a service network via the IP tunnel, including obtaining an inner IP address from an address space of the service network; performing the steps of: receiving a request for location information for the UE from a Packet Delivery Network Gateway, PDN-GW or authentication, authorisation and accounting, AAA, server; sending a request for location information for the UE to the DHCP server of the managed access network, the request for location information comprising the outer IP address of the UE; receiving a response containing location information for the UE from the DHCP server; sending a response containing the location information for the UE to the PDN-GW or AAA server. receiving a request for location information for the UE from a Packet Delivery Network Gateway, PDN-GW or authentication, authorisation and accounting, AAA, server; sending a request for location information for the UE to the DHCP server of the managed access network, the request for location information comprising the outer IP address of the UE; receiving a response containing location information for the UE from the DHCP server; sending a response containing the location information for the UE to the PDN-GW or AAA server.
