Document Type and Number:
WIPO Patent Application WO/2022/095630
Kind Code:
A1
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 (S101), from a terminal device, a request for assigning a network address prefix; determining (S102) whether the network address prefix is assigned by the control plane function or a user plane function; transmitting (S103), 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 (S104), from the user plane function, a PFCP Session Modification Response including an assigned network address prefix; and transmitting (S105) 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.
