Embodiment Construction

[0030] As mentioned above, user equipment (UE) 102 needs to register with the network in order to receive services requiring registration. now refer to figure 1 , figure 1 An exemplary 5G communication system 100 is shown. The 5G communication system 100 shows a point-to-point reference point representation. exist figure 1 In , some nodes and functions of the network are shown. User Equipment (UE) 102 connects to the network via Radio Access Network Node (RAN) 108 . The RAN may be eg a base station, NodeB or eNodeB. It should be noted that a UE may be a mobile phone, such as a smartphone, or some other type of unit with wireless communication capabilities, such as an Internet of Things (IoT) device, machine-to-machine device, vehicle, sensor, computer, laptop, etc. The RAN 108 is in turn connected to the core network, which includes the User Plane Function (UPF) 112, Access and Mobility Management Function (AMF) 104, Session Management Function (SMF) 106, Policy Control ...

Abstract

The present invention relates to PDU session management and in particular methods and devices for establishing user plane resources for PDU sessions. This is realized in a number of embodiments such as methods and devices for an infrastructure node and user equipment node. For instance in a method for Protocol Data Unit, PDU, session management, with steps of receiving, at an Access and Mobility Management function entity, AMF, a registration request message transmitted by a user equipment, UE, wherein the registration request message comprises information indicating that one or more PDU sessions require user plane, UP, resources and identifying each of the PDU sessions that require UP resources, and in response to receiving the registration request message, the AMF transmitting to a session management function, SMF, a UP resource request message for requesting the SMF to establish UP resources for at least one of the PDU sessions that requires UP resources. The method may further comprise in response to receiving the UP resource request message, the SMF triggers a UP function relocation.

Description

technical field [0001] The present invention relates to PDU session management, and in particular to establishing user plane resources for PDU sessions. Background technique [0002] In the field of telecommunications, there is a continuous evolutionary development for providing efficient and reliable solutions for utilizing wireless communication networks. Each new generation presents its own technical challenges for handling the different situations and processes required to connect and service devices connected to wireless networks. This is especially true for cellular telecommunications networks. [0003] A cellular telecommunication network comprises at a high level access infrastructure and core infrastructure. The access infrastructure provides wireless access to connected devices and handles the connectivity of those devices. The core infrastructure provides authentication, billing, quality of service (QoS) handling, and similar user / device management features. F...
