摘要: 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.

摘要: Methods and systems for transferring monitoring event information during a mobility procedure are provided. According to one aspect, a method for transferring monitoring event information during a mobility procedure comprises, at a first network node: receiving and storing subscription information indicating that a second network node has subscribed to get notification when there is a data delivery failure involving a User Equipment (UE), followed by the UE becoming reachable; detecting a data delivery failure involving the UE, and setting a flag to indicate that a data delivery failure involving the UE has occurred; receiving, from a third network node, a mobility related request; sending, to the third network node, a response to the mobility related request, comprising an indication that the third network node should notify the second network node when the UE becomes reachable and/or when then UE enters the IDLE state.
