Abstract: A method in a mobility management node for handling information in a network. The node is associated with a wireless device being served by a serving network. The node obtains information about that at least one of the serving network and a time zone and a UCI, has been changed for the device, and information about that the change has not been transmitted to a SGW. When at least one of the serving network and the time zone and the UCI, has been changed, and information about the change has not been transmitted to the SGW, the node transmits the information about at least one of the changed serving network and time zone and UCI, to the SGW, enabling the SGW to forward this information to a PGW.

Abstract: Systems and methods are disclosed for providing an enhanced Packet Forwarding Control Protocol (PFCP) association procedure for session restoration. In this regard, a method performed by a PFCP node comprises deleting one or more PFCP sessions of the PFCP node that are associated with a failed PFCP entity or with a failed PFCP path. The method further comprises sending, to a PFCP peer node, a node level message to request that the PFCP peer node delete a corresponding one or more PFCP sessions of the PFCP peer node that are associated with the failed PFCP entity or with the failed PFCP path, wherein the node level message comprises an indication of the corresponding one or more PFCP sessions. Some embodiments provide that the node level message comprises a PFCP Association Setup Request including sessions retention information to indicate whether to retain PFCP sessions associated with the PFCP Association Setup Request.

Abstract: Embodiments of the present disclosure provide methods and apparatuses for assigning network address prefix. A method performed by a control plane function may comprise: receiving, from a terminal device, a request for assigning a network address prefix; determining whether the network address prefix is assigned by the control plane function or a user plane function; transmitting, to the user plane function, a PFCP Session Modification Request for requesting the user plane function to assign the network address prefix, if it is determined that the network address prefix is assigned by the user plane function; receiving, from the user plane function, a PFCP Session Modification Response including an assigned network address prefix; and transmitting the assigned network address prefix to the terminal device. The specific procedure for the terminal device to obtain the network address prefix from a network entity not directly requested by the terminal device may be defined.
