The service provides a direct mapping of a quality of service flow between a packet data unit layer and a service data adaptation layer associated with a user plane function and a central unit-user plane function without an intermediary mapping of a tunneling protocol in the user plane. ## Claims ### Claim 1 A method comprising: receiving, by a network device, a message pertaining to an establishment of packet data unit (PDU) session for an end device; determining, by the network device, that the message includes collocation guidance information; selecting, by the network device in response to the determining, a user plane function and a central unit-user plane function of the network device; and mapping, by the user plane function and the central unit-user plane function, a quality of service flow to the PDU session directly with a radio bearer without an intermediary mapping of a General Packet Radio Service Tunneling Protocol User Plane (GTP-U) tunnel, wherein the quality of service flow includes at least one of uplink or downlink user plane data. ### Claim 2 (depends on 1) The method of claim 1, wherein the network device is of a fifth generation wireless network. ### Claim 3 (depends on 1) The method of claim 1, wherein the message includes a first message from a session management function and a second message from a central unit-control plane function. ### Claim 4 (depends on 3) The method of claim 3, wherein the first message includes data indicating a selection of the user plane function and the second message includes data indicating a selection of the central unit-user plane function. ### Claim 5 (depends on 1) The method of claim 1, wherein the mapping comprises mapping the quality of service flow between a PDU layer and a Service Data Adaptation Protocol (SDAP) layer. ### Claim 6 (depends on 5) The method of claim 5, wherein the collocation guidance information indicates to use direct mapping between the PDU layer and the SDAP layer. ### Claim 7 (depends on 1) The method of claim 1, further comprising: transmitting, by the network device subsequent to the mapping, downlink user plane data of the quality of service flow to a distributed unit-user plane function via an F1-U interface. ### Claim 8 (depends on 1) The method of claim 1, further comprising: transmitting, by the network device subsequent to the mapping, uplink user plane data of the quality of service flow to a data network via an N6 interface. ### Claim 9 A network device comprising: a communication interface; a memory, wherein the memory stores instructions; and a processor, wherein the processor executes the instructions to: receive, via the communication interface, a message pertaining to an establishment of packet data unit (PDU) session for an end device; determine that the message includes collocation guidance information; select, in response to the determination, a user plane function and a central unit-user plane function of the network device; and map, by the user plane function and the central unit-user plane function, a quality of service flow to the PDU session directly with a radio bearer without an intermediary mapping of a General Packet Radio Service Tunneling Protocol User Plane (GTP-U) tunnel, wherein the quality of service flow includes at least one of uplink or downlink user plane data. ### Claim 10 (depends on 9) The network device of claim 9, wherein the network device is of a fifth generation wireless network. ### Claim 11 (depends on 9) The network device of claim 9, wherein the message includes a first message from a session management function and a second message from a central unit-control plane function. ### Claim 12 (depends on 11) The network device of claim 11, wherein the first message includes data indicating a selection of the user plane function and the second message includes data indicating a selection of the central unit-user plane function. ### Claim 13 (depends on 9) The network device of claim 9, wherein the mapping comprises mapping the quality of service flow between a PDU layer and a Service Data Adaptation Protocol (SDAP) layer. ### Claim 14 (depends on 13) The network device of claim 13, wherein the collocation guidance information indicates to use direct mapping between the PDU layer and the SDAP layer. ### Claim 15 (depends on 9) The network device of claim 9, wherein the processor further executes the instructions to: transmit, via the communication interface subsequent to the mapping, downlink user plane data of the quality of service flow to a distributed unit-user plane function via an F1-U interface. ### Claim 16 (depends on 9) The network device of claim 9, wherein the processor further executes the instructions to: transmit, via the communication interface subsequent to the mapping, uplink user plane data of the quality of service flow to a data network via an N6 interface. ### Claim 17 A non-transitory computer-readable storage medium storing instructions executable by a processor of a network device, which when executed cause the network device to: receive a message pertaining to an establishment of packet data unit (PDU) session for an end device; determine that the message includes collocation guidance information; select, in response to the determination, a user plane function and a central unit-user plane function of the network device; and map, by the user plane function and the central unit-user plane function, a quality of service flow to the PDU session directly with a radio bearer without an intermediary mapping of a General Packet Radio Service Tunneling Protocol User Plane (GTP-U) tunnel, wherein the quality of service flow includes at least one of uplink or downlink user plane data. ### Claim 18 (depends on 17) The non-transitory computer-readable storage medium of claim 17, wherein the network device is of a fifth generation wireless network. ### Claim 19 (depends on 17) The non-transitory computer-readable storage medium of claim 17, wherein the message includes a first message from a session management function and a second message from a central unit-control plane function. ### Claim 20 (depends on 17) The non-transitory computer-readable storage medium of claim 17, wherein the instructions to map further comprise instructions, which when executed cause the network device to: map the quality of service flow between a PDU layer and a Service Data Adaptation Protocol (SDAP) layer.
