A method performed by an access manager of transferring data in a wireless communication system comprising a control plane distributed over at least one first site and over at least one second site , wherein a session manager is arranged in the control plane of the second site and the access manager is arranged in the control plane of the first site , the first site being remote from the second site and located physically closer to a radio access network of the wireless communication system, comprising: receiving (S201), from a target base station to which a wireless communication device is to be handed over, a path switch request where access of the wireless communication device is being transferred from a source base station to the target base station, the base stations being connected to said at least one first site ; further being characterized in comprising: providing (S202) one or more User Plane Functions , UPFs, serving the wireless communication device with information identifying the target base station and information identifying the wireless communication device , wherein the information is provided to the one or more UPFs without passing the control plane of the second site ; and acquiring (S206), from the session manager , information indicating if the access manager is allowed to finish its path switch request procedure without informing the session manager that the access of the wireless communication device is being transferred; and if so finishing (S207) the path switch request procedure without informing the session manager that the access of the wireless communication device is being transferred. receiving (S201), from a target base station to which a wireless communication device is to be handed over, a path switch request where access of the wireless communication device is being transferred from a source base station to the target base station, the base stations being connected to said at least one first site ; further being characterized in comprising: providing (S202) one or more User Plane Functions , UPFs, serving the wireless communication device with information identifying the target base station and information identifying the wireless communication device , wherein the information is provided to the one or more UPFs without passing the control plane of the second site ; and acquiring (S206), from the session manager , information indicating if the access manager is allowed to finish its path switch request procedure without informing the session manager that the access of the wireless communication device is being transferred; and if so providing (S202) one or more User Plane Functions , UPFs, serving the wireless communication device with information identifying the target base station and information identifying the wireless communication device , wherein the information is provided to the one or more UPFs without passing the control plane of the second site ; and acquiring (S206), from the session manager , information indicating if the access manager is allowed to finish its path switch request procedure without informing the session manager that the access of the wireless communication device is being transferred; and if so finishing (S207) the path switch request procedure without informing the session manager that the access of the wireless communication device is being transferred. <EOS>
