In one aspect of the present invention is used as an attribute of the major cellular network data transmission path defining the PDU session (Attribute), AMF NAS between terminal a signaling message (CM provided IDLE or CM-a CONNECTED state defined) PDU number UP session follows according to determine whether connected or hypermetropia. Another specific PDU session including a plurality of UPF primary subject matter relates when maintaining or if the terminal are liver N9 UPF CM provided IDLE state number follows number to determine whether the tunnel or hypermetropia. If the first to specifically, NAS PDU session attribute with a signaling message to detect whether a synchronization indicator (Indication) can be introduced. Said indicator is determined by SMF PDU Session Establishment procedures can be. Said Establishment procedure includes storing (Association) on mapping of PDU Session ID AMF Serving SMF ID where it is, there is a synchronization indicator with said NAS PDU session signaling message according can be separately stored. Specific PDU session (or presence) when said indicator On NAS signaling connection is set up back (CM-a CONNECTED state entry), UP session involving said PDU set up procedure can be connected. On the other hand, said indicator (or not present) session specific PDU Off NAS signaling connection is set up back even without said PDU UP connection session set up procedure thereof can. The session is said PDU traffic occurs is relayed to said PDU session UP connection to set up each other. Said PDU Session Establishment completed PDU Session Establishment Accept message is transferred is ready SMF determined in said indicator which can be utilized when creating Service Request message sent along subsequent terminal can be. Said NAS synchronization with the indicators to detect whether a signaling message can be determined through the following method. First, subscription information of said PDU Session Establishment UE (Subscription Data) is stored for managing UDM SMF procedures can be obtained from in UDM. Second, in the event of a subsequent policy (Policy) PCF said indicator from said PDU Session Establishment procedure information about policies on SMF UE can be transmitted to the terminal. Third, said PDU Session Establishment procedure can directly enters a PDU Session Establishment Request UE is specified. The SMF exists and is finally determined indicator on said indicator in AMF UE can be for information. Then, terminal a data according to the number N2 Release procedure for the NAS signaling connected not to be carried out by RAN or AMF. CM provided IDLE state into a terminal by a network or terminal by performing a Service Request procedure can be CM provided CONNECTED state is. The terminal determines whether the session signaling message synchronization with said NAS On indicator for the PDU PDU Session ID NAS Service Request do not contain a signaling message can be transmitted. Said Service Request message on his Serving SMF ID stored with the AMF is managing the PDU Session ID mapping of said indicator with respect to session based on said indicator information can be PDU Session Activation On fpr. The AMF said PDU Session Activation procedure for managing session is a session of said PDU SMF UP connection setup for request message can be sent together on said PDU Session ID. The CM provided IDLE state terminal by the network can be operate similarly even when Service Request fpr. The AMF Tracking a terminal a position unit (e. G. Tracking Area List) up through all RAN Paging Paging belonging to this in response to receiving terminal sends Paging Response to be coated. Upon reception of the AMF said Paging Response, is one of the prior described as to obtain a mapping of said indicator information stored with the PDU Session ID managing Serving SMF ID on the PDU Session Activation On session based on said indicator can be respect to fpr. AMF is synchronized with a signaling message is an indication of the own On NAS PDU session said PDU Session Activation procedure SMF signaling associated with the terminal session before transmission service is not allowed said PDU Session Activation procedure determines the Non provided Allowed Area 12 be not intended to perform. CM-a CONNECTED state terminal transmitting does not occur by regular time abnormality data is for connecting the number N2 Release RAN or AMF NAS signaling can be fpr. The AMF is said indicator for the PDU session by connecting to a number UP On all purposes for managing session can be all SMF PDU PDU Session Deactivation to fpr. In addition, PDU according to CM-a CONNECTED state terminal independent passive periods of a session when a session activation procedure support can be taking into account. Each session by connecting to a number UP RAN non-activation procedure, AMF, or can be performed by SMF Anchor UPF. First non-activation when said NAS Triggering AMF AMF manages PDU Session ID of the own synchronized with a signaling message to request an indication of the order PDU Session Deactivation On SMF operable to be not in session. Next SMF Triggering SMF non-activation if a signaling message identifying said NAS session according an indication whether synchronization with PDU Session Deactivation procedure can be directly are not intended to perform. In RAN UPF Triggering SMF PDU Session Deactivation procedure or also be the case by not cause synchronization with an indication of the whether a signaling message to said NAS On in session can be preventing independent passive periods of a session. If the second respect to specifically, terminal device includes a plurality of UPF participates to a particular PDU session request, the connection between the terminal and an outer DN (Data Network) is responsible for connection with Anchor UPF UE RAN UP on DRB between, and N3 N3 between tunnel RAN End-a point in UPF tunnel, N3 N6 End-a point on tunnel interface between N9 consisting in UPF End-a point in Anchor UPF tunnel can be. Figure 2 terminal of one PDU session setup when 2 exhibits. The PDU session 1 (UPF3) that the session is set up the session one UPF becoming, UP connection consisting on tunnel while DRB N3, PDU session 2 2 is that the session is set up the session of UPF (UPF1 and UPF2) on DRB becoming, UP connection tunnel and N9 N3 consists of a tunnel. Said PDU session 2 such as a plurality of UPF UP PDU session connection set up through the, terminal in state transition or independent or is hereinafter CM provided CONNECTED CM provided IDLE supporting passive periods of a session when an activation procedure, when connected to said PDU UP session number corresponding session number N3 the tunnel is only on the DRB UPF but without being maintaining N9 the tunnel is between can be eliminated. This later occur MO/MT rotate by receiving and transmitting corresponding PDU session traffic can be tuned are disclosed. In PDU Session Establishment including plurality of UPF fpr, notification of a change in the AMF is to SMF UE Location (Notification) can request to receive. Said request is informed to AMF SMF is for delivering or indicator, such as AMF is UE Location Report method implemented through subscribing service checks if the service number can be like. Said UE Location information cell (Cell) or a base station ID unit as well as TA (Tracking Area) for locating a terminal such as the day notified of the units identified in the diagram for core network are disclosed. The session is requested with respect to the AMF is UE Location upon change, notifying diffuse to the SMF. The notification is received at said UE Location SMF N3 tunnel is in service procedure confirms UE Location UPF End-a point of including an OPC process is performed, said UPF still service area of region included in 12, said UPF Anchor UPF N9 on tunnel session between said PDU to maintain substrate. If a service area of said UPF Query SMF UPF is directly does not manage any service can be belongs to the identifying. If said UE Location said UPF is not included in the service area of the mounted, said N9 to number can tunnel. The, selects a new tunnel is to select an optimal N3 SMF UE Location regarding the same level with said Anchor UPF End-a point UPF tunnel N9 disapproval. In addition, tunnel is held to said N9/number and change management solution can be performed based on information associated with said UE Location to be performed by as well as other conditions may be filled. In one example, QoS requirements including QoS profile (or parameter) 5GC PDU session is to be assigned from which, said QoS profile includes data received by said N9 SMF number or a new tunnel is set up a tunnel can be area for I-a UPF N9. In the alteration of the RAN said QoS profile corresponding session QoS profile when the change notification may receive or UDM PCF or can include disclosed. Said QoS profile is a PDU session per Session Aggregate Maximum Bit Rate per UE Aggregate Maximum Bit Rate (UE provided AMBR) (Session provided AMBR) and each may have, in the case of QoS Flow GBR (Guaranteed Bit Rate), and Maximum Flow Bit Rate Guaranteed Flow Bit Rate (GFBR) comprising (MFBR) can be. In addition, in the case of 5G QoS Indicator 5GC (5QI) is Resource Type (GBR or Non-a GBR), Priority level, including Packet Delay Budget and Packet Error Rate can set, can be value of such means. The alteration of the PDU Session Modification procedure can be conducted via said QoS profile. In addition, tunnel is held to said N9/number and change management solution can be associated with dynamic load (Load) constituting UPF N9 tunnel receives input state can be performed. In particular, to manage its own load of the SMF UPF when status monitoring, beyond a particular threshold (Threshold) transmitting said Intermediate UPF Anchor UPF Intermediate UPF non load path to the N9 PDU using tunnel session number is (i.e., the load is less than the threshold) or congestion is detected can be N9 tunnel area for new Intermediate UPF. The amount of data traffic through said UPF UPF number or string corresponding dynamic unloaded condition with reference to the number of session setup is placed on the relative doses (Relative Capacity) PDU UPF and the like can be determined by. In addition, tunnel is held to said N9/number and change associated with a particular session of terminal management can be performed based on required UPF Capability or Functionality. In one example, terminal session set-up used in the DNN (Data Network Name), APN (Access Point Name), NSSAI (Network Slice Selection Assistance Information), UE Usage Type, SSC (Service and Session Continuity) Mode, such as requirements of the UPF SMF Service Type for time functionality/capability and can be derived by, said SMF Intermediate UPF therefrom is the number corresponding to the N9 is said Functionality/Capability does not satisfy the PDU Anchor UPF determines that a tunnel session only a method for maintaining or, said Functionality/Capability selects a new Intermediate UPF N9 satisfying the tunnel newly setup can be disclosed. In addition, tunnel is held to said N9/number and change the UE mobility pattern associated with management can be performed (Mobility Pattern) receives its input. In one example, 5GC of AMF is thick or may be obtained from calculating the mobility of UE 3rd Party server are disclosed. Mobility of said AMF UE is greater beyond the specified threshold (e. G. , Generated during a particular period of time when a threshold number of handover) 12 and, to said UE SMF can be on an information report. Then, said SMF is of said UE (UP inactive is connected) to the N9 PDU session number N9 tunnel to tunnel to reduce signaling load for updating, a new Intermediate UPF Anchor UPF selecting a wider service area according to new N9 on tunnel setup by a reduced number of update to N9 tunnel can be. Said UE mobility pattern information about a particular PDU session when said UE SMF in deactivating, Intermediate UPF Anchor UPF number N9 on liver can be used to decide whether to maintain the tunnel. In addition, a plurality of session engine is said PDU Anchor UPF, next a-hop tunnel end N3 on the Intermediate UPF said N9 the tunnel is base station in said plurality of Anchor UPF branched Branching Point or Uplink Classifier serves for a traffic tunnel can be Intermediate UPF N9 between means. A plurality of UPF UP through PDU can be taken into account in the connection set up session is roaming scenario. Such as in the case of roaming Home Routed HPLMN (Home PLMN) also 3 on UPF there between to N9 (Visisted PLMN) of VPLMN UPF of tunnel, said N9 the tunnel is terminal NAS signaling connection state and session as the deactivation of PDU to maintain substrate. The HPLMN of SMF VPLMN is allowed to local offloaded by in (Local Offloading) between the command and before another UPF UPF RAN additionally in number and can be, in the present invention number of subscribers in the network VPLMN UPF subjected to liver-in holding and to a number of tunnel N9 N9 tunnel can be applied on an enlarged VPLMN AMF SMF through signaling between it will rain. In the case of a roaming scenario in Figure 4 of another such as AMF SMF VPLMN Local Breakout roaming on the PDU session in the present invention number N9 through signaling between tunnel-in holding and to present a number N9 tunnel may be applying control are disclosed. Hereinafter specific embodiment example of the present invention through major operation other.

Step 9 is N2 (R) wherein at least one of the AMF AN NAS message in message delivery, the received AN UPF (R) set up a tunnel of a process by means of N2 from the message. Step 10 (R) in the DRB on session AN UE UE NAS message comprises and setup to process. Step 11 (R) through one tunnel information so that it is carried out in step 9 AN N3 sends the setup signaling comprises ACK that directs the process to the AMF. Step 12 (R) is received by a switch and tunnel information in AMF AN SMF N3, N3 SMF End-a point (R) in step 13 through tunnel is created to AN UPF1 N3 N3 to tunnel information for data transmission tunnel setup is completed with each other. Step 14 is for setup tunnel related information may be obtained through Anchor UPF N9 tunnel N9 are both tunnel setup is completed. Step 15 connected through said session in addition to signaling to all UP-like AMF can send, if I hadn't the AMF SMF UE position in subsequent stages is requesting notification of said notification request to can. Then, in the case of session type IPv6 PDU, SMF is a newly assigned IP prefix information to Router Advertisement message to be capable of delivering via a modified Anchor UPF UP signalling in UE. Example><number 8 embodiment When a terminal are examples CM provided IDLE state number 8 embodiment, consisting of a plurality of UPF PDU session number to the N9 tunnel for operation other. Figure 18 shows a example embodiment are also etched during a procedure. Step 1 is the AMF and to reduce a transferring process to the notification of change of location for said UE SMF N11 message comprises. Step 2 is notified from the AMF UE position belongs to a service area of the outer surface of the resulting UPF1 based on determining, if UPF1 determining existing tunnel connected to the N9 when deviating from the service area of that is the number comprises the set up process. Step 3 and 4 includes a tunnel through the tunnel for signaling SMF N9 number N3 in UPF1 Anchor UPF UPF2 and exchanged 10z. End-a point in. The, for the Downlink Data Buffering Session Modification Anchor UPF include the size of a storable, N3 UPF1 Session Release End-a point that is in tunnel can be performed. Further, the tunnel setup it necessary that new UE SMF N9 position 12, a suitable position on said Anchor UPF UPF selects a new UE said new N9 fpr tunnel can be set up. Tunnel session when said PDU N9 newly partially, the AMF SMF UE to delay is not longer notification to request to control including a sync channel message can be N11 (step 5). Figure 19 on a suitable UPF selects a new UE position comprising said Anchor UPF new N9 tunnel set up procedure. Example><number 9 embodiment Other conditions by maintaining said UE Location number 9 embodiment examples other than information number and modification shown is constructed to tunnel N9/2000. In one example, a change of the PDU session can be assigned QoS profile. In addition, tunnel is held to said N9/number and change management solution can be associated with dynamic load (Load) constituting UPF N9 tunnel receives input state can be performed. In addition, tunnel is held to said N9/number and change the UPF Functionality/Capability receives inputs associated with management technique can be performed. In addition, tunnel is held to said N9/number and change the UE mobility pattern associated with management can be performed (Mobility Pattern) receives its input.
