Description

[Technical Field]

[0001] Technical Field The present disclosure relates generally to wireless communications, including, but not limited to, systems and methods for non-public network (NPN) measurements. [Background technology]

[0002] background The 3rd Generation Partnership Project (3GPP®), a standards organization, is currently defining a new air interface called 5G New Radio (5G NR) and the Next Generation Packet Core Network (NG-CN or NGC). 5G NR has three main components: the 5G Access Network (5G-AN), the 5G Core Network (5GC), and the User Equipment (UE). To facilitate the enablement of different data services and requirements, the elements of the 5GC, also known as network functions, have been simplified; some of them are software-based and some are hardware-based, so they can be adapted as needed.

[0021] Detailed Description 1. Mobile communication technology and the environment 1 illustrates an exemplary wireless communication network and / or system 100 in which the techniques disclosed herein may be implemented, according to embodiments of the present disclosure. In the following description, the wireless communication network 100 may be any wireless network, such as a cellular network or a narrowband Internet of Things (NB-IoT) network, and is referred to herein as “network 100.” Such exemplary network 100 includes a base station 102 (hereinafter “BS 102,” also referred to as a wireless communication node) and a user equipment device 104 (hereinafter “UE 104,” also referred to as a wireless communication device) that can communicate with each other via a communication link 110 (e.g., a wireless communication channel), and a cluster of cells 126, 130, 132, 134, 136, 138, and 140 that overlap a geographic area 101. In FIG. 1, the BS 102 and the UE 104 are contained within the respective geographic boundaries of the cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one base station operating in its assigned bandwidth to provide adequate radio coverage to intended users.

[0022] For example, the BS 102 may operate in an assigned channel transmission bandwidth to provide adequate coverage to the UE 104. The BS 102 and the UE 104 may communicate via downlink radio frames 118 and uplink radio frames 124, respectively. Each radio frame 118 / 124 may be further divided into subframes 120 / 127, which may include data symbols 122 / 128. In this disclosure, the BS 102 and the UE 104 are generally described herein as non-limiting examples of "communication nodes" capable of practicing the methods disclosed herein. Such communication nodes may be capable of wireless and / or wired communication in accordance with various embodiments of the present solution.

[0023] 2 illustrates a block diagram of an exemplary wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) in accordance with some embodiments of the present solution. System 200 may include components and elements configured to support known or conventional operational features that need not be described in detail herein. In one exemplary embodiment, system 200 may be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment, such as wireless communication environment 100 of FIG. 1, as previously described.

[0024] The system 200 generally includes a base station 202 (hereinafter "BS 202") and a user equipment device 204 (hereinafter "UE 204"). The BS 202 includes a BS (base station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each of which is coupled and interconnected as needed via a data communication bus 220. The UE 204 includes a UE (user equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each of which is coupled and interconnected as needed via a data communication bus 240. The BS 202 communicates with the UE 204 over a communication channel 250, which may be any wireless channel or other medium suitable for the transmission of data as described herein.

[0025] As will be appreciated by those skilled in the art, system 200 may further include any number of modules other than those illustrated in FIG. 2 . Those skilled in the art will appreciate that the various exemplary blocks, modules, circuits, and processing logic described in connection with the embodiments disclosed herein may be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this compatibility and suitability of hardware, firmware, and software, the various exemplary components, blocks, modules, circuits, and steps are described generally in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software may depend on the particular application and design constraints imposed on the overall system. Those familiar with the concepts described herein may implement such functionality in a manner suitable for each particular application, but such implementation decisions should not be interpreted as limiting the scope of the present disclosure.

[0026] According to some embodiments, the UE transceiver 230 may be referred to herein as an “uplink” transceiver 230 that includes a radio frequency (RF) transmitter and an RF receiver, each with circuitry coupled to an antenna 232. Alternatively, a duplexing switch (not shown) may couple the uplink transmitter or receiver to the uplink antenna in a time-duplexed manner. Similarly, according to some embodiments, the BS transceiver 210 may be referred to herein as a “downlink” transceiver 210 that includes an RF transmitter and an RF receiver, each with circuitry coupled to an antenna 212. Alternatively, a downlink duplexing switch may couple the downlink transmitter or receiver to the downlink antenna 212 in a time-duplexed manner. The operation of the two transceiver modules 210 and 230 may be time-coordinated such that the downlink transmitter is coupled to the downlink antenna 212 at the same time that the uplink receiver circuitry is coupled to the uplink antenna 232 for receiving transmissions over the wireless transmission link 250. Conversely, the operation of the two transceivers 210 and 230 may be time-coordinated such that the uplink transmitter is coupled to the uplink antenna 232 at the same time that the downlink receiver is coupled to the downlink antenna 212 for receiving transmissions over the wireless transmission link 250. In some embodiments, there is close time synchronization with a minimum guard time between changes in duplex direction.

[0027] The UE transceiver 230 and the base station transceiver 210 are configured to communicate over a wireless data communication link 250 and cooperate with appropriately configured RF antenna devices 212 / 232 capable of supporting a particular wireless communication protocol and modulation scheme. In some exemplary embodiments, the UE transceiver 210 and the base station transceiver 210 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G standards. However, it will be understood that the present disclosure is not necessarily limited to application to a particular standard and associated protocol. Rather, the UE transceiver 230 and the base station transceiver 210 may be configured to support alternative or additional wireless data communication protocols, including future standards or variants thereof.

[0028] According to various embodiments, the BS 202 may be, for example, an evolved node B (eNB), a serving eNB, a target eNB, a femto station, or a pico station. In some embodiments, the UE 204 may be embodied in various types of user devices, such as a mobile phone, a smartphone, a personal digital assistant (PDA), a tablet, a laptop computer, a wearable computing device, etc. The processor modules 214 and 236 may be implemented or realized using a general-purpose processor, a content-addressable memory, a digital signal processor, an application-specific integrated circuit, a field-programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. As such, a processor may be realized as a microprocessor, a controller, a microcontroller, a state machine, etc. A processor may also be implemented as a combination of computing devices, e.g., a combination of a digital signal processor and a microprocessor, multiple microprocessors, one or more microprocessors in combination with a digital signal processor core, or any other such configuration.

[0029] Furthermore, the steps of a method or algorithm described in connection with the embodiments disclosed herein may be embodied directly in hardware, firmware, a software module executed by processor modules 214 and 236, respectively, or any practical combination thereof. Memory modules 216 and 234 may be realized as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 216 and 234 may be coupled to processor modules 210 and 230, respectively, such that processor modules 210 and 230 can read information from and write information to memory modules 216 and 234, respectively. Memory modules 216 and 234 may also be integrated into respective processor modules 210 and 230. In some embodiments, memory modules 216 and 234 may each include a cache memory for storing temporary variables or other intermediate information during execution of instructions executed by processor modules 210 and 230, respectively. Memory modules 216 and 234 may also each include non-volatile memory for storing instructions executed by processor modules 210 and 230, respectively.

[0030] The network communications module 218 generally represents the hardware, software, firmware, processing logic, and / or other components of the base station 202 that enable bidirectional communications between the base station transceiver 210 and other network components and communication nodes configured to communicate with the base station 202. For example, the network communications module 218 may be configured to support Internet or WiMAX traffic. In a typical deployment, without limitation, the network communications module 218 provides an 802.3 Ethernet interface to enable the base station transceiver 210 to communicate with conventional Ethernet-based computer networks. As such, the network communications module 218 may include a physical interface for connecting to a computer network (e.g., a mobile switching center (MSC)). As used herein with respect to a specified operation or function, the terms “configured for,” “configured to,” and conjugations thereof refer to devices, components, circuits, structures, machines, signals, etc. that are physically configured, programmed, formatted, and / or arranged to perform the specified operation or function.

[0031] The Open Systems Interconnection (OSI) model (referred to herein as the "Open Systems Interconnection Model") is a conceptual and logical layout that defines network communications used by open systems (e.g., wireless communication devices, wireless communication nodes) to interconnect and communicate with other systems. The model is divided into seven subcomponents or layers, each of which represents a conceptual collection of services provided to the layers above and below it. The OSI model also defines logical networks and effectively describes computer packet transfers through the use of different layer protocols. The OSI model is sometimes referred to as the seven-layer OSI model or seven-layer model. In some embodiments, the first layer may be the physical layer. In some embodiments, the second layer may be the medium access control (MAC) layer. In some embodiments, the third layer may be the radio link control (RLC) layer. In some embodiments, the fourth layer may be the packet data convergence protocol (PDCP) layer. In some embodiments, the fifth layer may be the radio resource control (RRC) layer. In some embodiments, the sixth layer may be a non-access stratum (NAS) layer or an Internet Protocol (IP) layer, and the seventh layer is another layer.

[0032] To enable those skilled in the art to make and use the present solution, various exemplary embodiments of the present solution are described below with reference to the accompanying drawings. As will be apparent to those skilled in the art, after reading this disclosure, various changes or modifications to the examples described herein can be made without departing from the scope of the present solution. Thus, the present solution is not limited to the exemplary embodiments and applications described and illustrated herein. Furthermore, any specific order or hierarchy of steps in the methods disclosed herein is merely an example approach. Based on design preferences, the specific order or hierarchy of steps in a disclosed method or process can be rearranged while remaining within the scope of the present solution. Thus, those skilled in the art will understand that the methods and techniques disclosed herein present various steps or operations in a sample order, and that the present solution is not limited to the specific order or hierarchy presented, unless otherwise specified.

[0033] 2. Systems and methods for non-public network (NPN) measurements Due to the benefits of understanding user experience, Quality of Experience (QoE) / Minimized Drive-Rest (MDT) measurements have attracted the attention of operators / providers. Quality of Experience (QoE) measurements can be defined based on different applications. In some embodiments, QoE measurements may be performed at the application layer of the UE. QoE may include measurements of throughput, data loss, and / or latency. Minimized Drive-Rest (MDT) measurements may be a mechanism designed / developed / adapted to enable operators to collect mobile network data, including radio measurements and / or location information, using user devices in the network.

[0034] Both MDT and QoE measurements can be important for assessing network quality and / or user service quality. Both types of measurements can be triggered in a Next Generation Radio Access Network (NG-RAN) by direct configuration from an Operations, Administration, and Maintenance (OAM) system (e.g., management-based QoE / MDT (M-QoE / MDT), M-QoE, or M-MDT) or by signaling from the core network containing UE-related QoE / MDT configuration (e.g., signaling-based QoE / MDT (S-QoE / MDT), S-QoE, or S-MDT).

[0035] In 5G / 6G / other networks, Non-Public Network (NPN) functionality may be implemented. An NPN may be a Standalone Non-Public Network (SNPN) or a Public Network Integrated NPN (PNI-NPN). An SNPN may be a network deployed for non-public use that does not rely on network functionality provided by a Public Land Mobile Network (PLMN). A PNI-NPN may be a network deployed for non-public use that relies on network functionality provided by a PLMN. In a PNI-NPN, a Closed Access Group (CAG) may identify / contain a group of subscribers that are authorized to access a cell supporting the CAG. A PNI-NPN cell may support one or more CAGs.

[0036] Minimized Drive Test (MDT) and / or Quality of Experience (QoE) measurements may not support data collection in non-public networks (NPNs). When a UE accesses an NPN or camps on a cell in an NPN, QoE / MDT measurements may span several standalone non-public networks (SPNPs) and / or several different closed access groups (CAGs) within a public network integrated non-public network (PNI-NPN). However, the UE may not know / identify / inform which SNPNs / CAGs measurements should be collected.

[0037] Under the existing PNI-NPN, cells under a PLMN can support up to 12 CAGs. However, existing MDT / QOE measurements only need to specify which PLMNs should be measured by the UE. An operator may be interested / identify / notify only measurements of some CAGs, which may allow cells under PLMNs that do not support the relevant CAGs to be measured by the operator. In the case of SNPN cells (SNPNs not shared with a PLMN, or physical cells under a PLMN that may be shared by up to 12 SNPN networks), an operator may only be interested / identify / notify measurements of some SNPNs for network optimization of these SNPNs. As mentioned above, a UE may measure all SNPN networks or cells in PLMNs that do not support the CAGs of interest to the operator. This may result in a significant increase in UE energy consumption and / or air interface resource consumption.

[0038] Example 1: Management-based MDT for NPNs FIG. 3 shows a sequence diagram for management-based MDT for non-public network (NPN) measurements.

[0039] In step 1, an operation, administration, and maintenance (OAM) system may send a drive test minimization (MDT) configuration to the gNB to configure management-based MDT functionality in the gNB. The MDT configuration may include parameters for configuring MDT measurements. In addition to parameters in the MDT configuration (e.g., a list of measurements, a reporting trigger, a reporting interval, and a logging interval), the MDT configuration may also include an NPN range (of measurements for the UE). The NPN range may include at least one of a list of identifiers of standalone non-public networks (SNPNs) to indicate SNPNs allowed for the first measurement, or a list of identifiers of closed access groups (CAGs) to indicate public network-integrated non-public networks (PNI-NPNs) allowed for the first measurement. The first measurement may be an MDT and / or QoE measurement.

[0040] In step 2, when the UE accesses a non-public network (NPN) (e.g., an SNPN or PNI-NPN), the gNB may receive a new generation application protocol (NGAP) message associated with the UE (e.g., an initial context setup request, a UE context modification request, or a handover request). The NGAP may include management-based MDT (M-MDT) allowed NPN range information associated with the UE. The M-MDT allowed NPN range information may include at least one of a list of identifiers of standalone non-public networks (SNPNs) to indicate SNPNs allowed for the first measurement, or a list of identifiers of closed access groups (CAGs) to indicate public network-integrated non-public networks (PNI-NPNs) allowed for the first measurement. The first measurement may be an MDT and / or QoE measurement. The gNB may receive M-MDT allowed NPN range information of multiple UEs while the multiple UEs are accessing the NPN network.

[0041] In step 3, the gNB may select an appropriate UE for collecting MDT data. The selection may be based on the OAM for M-MDT configured NPN range and / or the M-MDT allowed NPN range of the corresponding UE received from the AMF. There may be a coherence between the M-MDT allowed NPN range of the corresponding selected UE and the OAM for M-MDT configured NPN range. The gNB may configure / set / align the NPN range in the MDT configuration associated with the UE according to the OAM for M-MDT configured NPN range and / or the M-MDT allowed NPN range of the corresponding UE received from the AMF. The NPN range (e.g., set / configured) may be in both the OAM for M-MDT configured NPN range and the M-MDT allowed NPN range of the corresponding UE received from the AMF. In some embodiments, the gNB may configure other parameters of the MDT configuration for the UE according to the OAM for M-MDT configured MDT configuration for the gNB in ​​step 1.

[0042] In step 4, the gNB may send a Radio Resource Configuration (RRC) message to activate MDT measurements for the UE. The RRC message may include an MDT configuration for the UE. The MDT configuration may comprise an NPN range (e.g., indicating a range for the first measurement). The NPN range may include at least one of a list of identifiers of standalone non-public networks (SNPNs) to indicate SNPNs allowed for the first measurement, or a list of identifiers of closed access groups (CAGs) to indicate public network-integrated non-public networks (PNI-NPNs) allowed for the first measurement. The first measurement may be an MDT and / or QoE measurement.

[0043] In step 5, while the UE is accessing or camping on the NPN network, the UE may perform MDT measurements according to the received NPN range. The UE may not perform MDT measurements outside the area / range identified by the NPN range.

[0044] In step 6, the UE may send an RRC message to report the MDT measurement result, which may include the associated SNPN identifier or CAG identifier of the specific NPN measurement result.

[0045] Example 2: Signaling-based MDT for NPN FIG. 4 illustrates a sequence diagram for signaling-based MDT for non-public network (NPN) measurements.

[0046] In step 1, when the UE accesses a non-public network (NPN) (e.g., an SNPN or PNI-NPN), the gNB may receive a New Generation Application Protocol (NGAP) message for MDT activation associated with the UE (e.g., an Initial Context Setup Request, a UE Context Modification Request, a Handover Request, or a Trace Start). The NGAP message may include an MDT configuration. The MDT configuration may include signaling-based MDT (S-MDT) allowed NPN range information. The S-MDT allowed NPN range information may include at least one of a list of identifiers of standalone non-public networks (SNPNs) to indicate SNPNs allowed for the first measurement, or a list of identifiers of closed access groups (CAGs) to indicate public-network-integrated non-public networks (PNI-NPNs) allowed for the first measurement. The first measurement may be an MDT and / or QoE measurement. The S-MDT allowed NPN range information in the corresponding NGAP message may be outside the MDT configuration.

[0047] In step 2, the gNB may configure an NPN range for MDT measurements associated with the UE according to the received S-MDT allowed NPN range information. The gNB may set / configure / align the NPN range for MDT measurements associated with the UE to be the same as the received S-MDT allowed NPN range. The gNB may send a Radio Resource Configuration (RRC) message to the UE. The RRC message may include an MDT configuration associated with the UE to activate MDT measurements for the UE. The MDT configuration may comprise an NPN range. The NPN range may include at least one of a list of identifiers of standalone non-public networks (SNPNs) to indicate SNPNs allowed for the first measurement, or a list of identifiers of closed access groups (CAGs) to indicate public network-integrated non-public networks (PNI-NPNs) allowed for the first measurement. The first measurement may be an MDT and / or QoE measurement.

[0048] In step 3, while the UE is accessing or camping on the NPN network, the UE may perform MDT measurements according to the received NPN range. The UE may not perform MDT measurements outside the area / range identified / covered by the NPN range.

[0049] In step 4, the UE may send an RRC message to report the MDT measurement result, which may include the associated SNPN identifier or CAG identifier of the specific NPN measurement result.

[0050] Example 3: Management-based QoE for NPNs FIG. 5 shows a sequence diagram for management-based QoE for non-public network (NPN) measurements.

[0051] In step 1, an operation, administration, and maintenance (OAM) system may send a quality of experience (QoE) configuration to the gNB to configure management-based QoE functionality in the gNB. The QoE configuration may include parameters for configuring QoE measurements. In addition to parameters in the QoE configuration (e.g., a list of measurements, a reporting trigger, a reporting interval, a logging interval, or a list of QoE metrics), the QoE configuration may also include an NPN range (of measurements for the UE). The NPN range may include at least one of a list of identifiers of standalone non-public networks (SNPNs) to indicate SNPNs allowed for the first measurement, or a list of identifiers of closed access groups (CAGs) to indicate public network-integrated non-public networks (PNI-NPNs) allowed for the first measurement. The first measurement may be a QoE and / or MDT measurement.

[0052] In step 2, when the UE accesses a non-public network (NPN) (e.g., an SNPN or PNI-NPN), the gNB may receive a new generation application protocol (NGAP) message associated with the UE (e.g., an initial context setup request, a UE context modification request, or a handover request). The NGAP may include management-based QoE (M-QoE) allowed NPN range information associated with the UE. The M-QoE allowed NPN range information may include at least one of a list of identifiers of standalone non-public networks (SNPNs) to indicate SNPNs allowed for the first measurement, or a list of identifiers of closed access groups (CAGs) to indicate public network-integrated non-public networks (PNI-NPNs) allowed for the first measurement. The first measurement may be a QoE and / or MDT measurement. The gNB may receive M-QoE allowed NPN range information for multiple UEs while the multiple UEs are accessing the NPN network.

[0053] In step 3, the gNB may select a suitable UE for collecting QoE data. The selection may be based on the configured NPN range of the OAM for M-QoE received from the AMF and / or the M-QoE allowed NPN range of the corresponding UE. There may be a coherence between the M-QoE allowed NPN range of the corresponding selected UE and the configured NPN range of the OAM for M-QoE. The gNB may configure / set / align the NPN range in the QoE configuration associated with the UE according to the configured NPN range of the OAM for M-QoE and / or the M-QoE allowed NPN range of the corresponding UE received from the AMF. The set NPN range may be in both the configured NPN range of the OAM for M-QoE and the M-QoE allowed NPN range of the corresponding UE received from the AMF. In some embodiments, the gNB may configure other parameters of the QoE configuration of the UE according to the configured QoE configuration of the gNB's OAM in step 1.

[0054] In step 4, the gNB may send a Radio Resource Configuration (RRC) message to activate QoE measurements for the UE. The RRC message may include a QoE configuration for the UE. The QoE configuration may include an NPN range. The NPN range may include at least one of a list of identifiers of standalone non-public networks (SNPNs) to indicate SNPNs allowed for the first measurement, or a list of identifiers of closed access groups (CAGs) to indicate public network-integrated non-public networks (PNI-NPNs) allowed for the first measurement. The first measurement may be a QoE and / or MDT measurement.

[0055] In step 5, while the UE is accessing or camping on the NPN network, the UE may perform QoE measurements according to the received NPN range. The UE may not perform QoE measurements outside the area / range identified / specified by the NPN range.

[0056] In step 6, the UE may send an RRC message to report the QoE measurement result, which may include the associated SNPN identifier or CAG identifier of the specific NPN measurement result.

[0057] Example 4: Signaling-based QoE for NPN FIG. 6 shows a sequence diagram for signaling-based QoE for non-public network (NPN) measurements.

[0058] In step 1, when the UE accesses a non-public network (NPN) (e.g., an SNPN or PNI-NPN), the gNB may receive a New Generation Application Protocol (NGAP) message for QoE activation associated with the UE (e.g., an Initial Context Setup Request, a UE Context Modification Request, a Handover Request, or a Trace Start). The NGAP message may include a QoE configuration. The QoE configuration may include signaling-based QoE (S-QoE) allowed NPN range information. The S-QoE allowed NPN range information may include at least one of a list of identifiers of standalone non-public networks (SNPNs) to indicate SNPNs allowed for the first measurement, or a list of identifiers of closed access groups (CAGs) to indicate public-network-integrated non-public networks (PNI-NPNs) allowed for the first measurement. The first measurement may be a QoE and / or MDT measurement. The S-QoE allowed NPN range information in the corresponding NGAP message may be outside the QoE configuration.

[0059] In step 2, the gNB may configure an NPN range for QoE measurements associated with the UE according to the received S-QoE allowed NPN range information. The gNB may set / align / configure an NPN range for QoE measurements associated with the UE to be the same as the received S-QoE allowed NPN range. The gNB may send a Radio Resource Configuration (RRC) message to the UE. The RRC message may include a QoE configuration associated with the UE to activate QoE measurements for the UE. The QoE configuration may include an NPN range. The NPN range may include at least one of a list of identifiers of standalone non-public networks (SNPNs) to indicate SNPNs allowed for the first measurement, or a list of identifiers of closed access groups (CAGs) to indicate public network-integrated non-public networks (PNI-NPNs) allowed for the first measurement. The first measurement may be a QoE and / or MDT measurement.

[0060] In step 3, while the UE is accessing or camping on the NPN network, the UE may perform QoE measurements according to the received NPN range. The UE may not perform QoE measurements outside the area / range identified by the NPN range.

[0061] In step 4, the UE may send an RRC message to report the QoE measurement result, which may include the associated SNPN identifier or CAG identifier of the specific NPN measurement result.

[0062] Example 5: Signaling-based QoE configuration for high-speed trains FIG. 7 shows a sequence diagram of a signaling-based QoE configuration (e.g., for a high-speed train / transport situation or scenario). For example, in a high-speed train scenario, a UE may experience frequent handovers while traveling at high speed. In FIG. 7, NG-RAN node 1 (e.g., gNB1) may refer to a first NG-RAN node to which the UE connects on the high-speed train. NG-RAN node 2 (e.g., gNB2) may be a second node to which the UE travels while traveling on the high-speed train. NG-RAN node X (e.g., gNB X) may be an NG-RAN node numbered X to which the UE travels on the corresponding high-speed train (X>=2).

[0063] In step 1, the NG-RAN node 1 can understand / determine that the UE is in a high velocity scenario according to the measurement results collected from the RAN side.

[0064] In step 2, the NG-RAN node 1 may send a high-speed indication to an Access and Mobility Management Function (AMF) to indicate that the UE is in a high-speed scenario (e.g., a scenario in which the UE is moving at a high speed, e.g., a speed higher than a defined threshold). The AMF may prepare a QoE configuration for the high-speed train.

[0065] In step 3, the AMF may send a dedicated QoE configuration associated with the UE in the high-speed train scenario to the NG-RAN node 1. The dedicated QoE configuration may include an indication that the wireless communication device is in a high-speed scenario or at least one of an area coverage / range indication including at least one of an extended list of cell identifiers for a wide area range (e.g., part or all of the areas of the high-speed train), an extended list of tracking areas (TAs) for a wide area range (e.g., part or all of the areas of the high-speed train), an extended list of public land mobile network (PLMN) identifiers for a wide area range (e.g., part or all of the areas of the high-speed train), an extended list of standalone non-public network (SNPN) identifiers for a wide area range (e.g., part or all of the areas of the high-speed train), or an extended list of closed access group (CAG) identifiers for a wide area range (e.g., part or all of the areas of the high-speed train). The area coverage / range indication may cover part or all of the areas along the high-speed train. The broad area range can be a range and / or area that meets and / or exceeds a defined / configured / standard threshold. In some embodiments, the broad area range can be a range within a defined / configured / standard range.

[0066] In step 4 (optional), the AMF may store the dedicated QoE configuration.

[0067] After steps 1 to 4, the NG-RAN node 1 can send a dedicated QoE configuration to the UE. The dedicated QoE configuration may include a dedicated area range to the UE. The UE may perform QoE measurements according to the dedicated area / range. The UE may not perform QoE measurements outside the area / range identified by the dedicated area range. When the UE travels on a high-speed train, the UE may experience frequent handovers (e.g., the UE moves to NG-RAN node X (X>=2)).

[0068] In step 5, to reduce consumption of handover signaling resources, the source NG-RAN node may not carry the QoE configuration to the target NG-RAN node X in the handover request message. The NG-RAN node X may send a New Generation Application Protocol (NGAP) message (e.g., a QoE configuration request message) to the AMF to request a QoE configuration associated with the UE.

[0069] In step 6, the AMF may respond to the QoE configuration request message by sending the stored dedicated QoE configuration to NG-RAN node X.

[0070] After step 6, the NG-RAN node X can recognize the QoE configuration on the UE side. Continuity of QoE measurements can be supported for the UE in high-speed scenarios.

[0071] It should be understood that one or more features from the above example embodiments are not limited to a particular example embodiment and can be combined in any manner (e.g., in any priority and / or order, simultaneously or otherwise).

[0073] A wireless communication node (e.g., a gNB) may transmit to a wireless communication device (e.g., a UE) a first radio resource configuration (RRC) message including a first configuration (e.g., an MDT and / or QoE configuration) including an indication of a non-public network (NPN) range of a first measurement (e.g., an MDT and / or QoE measurement) to be performed by the wireless communication device.

A subsequent wireless communication node (e.g., NG-RAN node X) being accessed by the wireless communication device may send a New Generation Application Protocol (NGAP) message to the AMF to request the QoE configuration. The AMF may obtain / access a copy of the stored QoE configuration and may transmit the QoE configuration to the subsequent wireless communication node in response to the NGAP message.

[0080] In some embodiments, a wireless communication device (e.g., a UE) may receive a first radio resource configuration (RRC) message from a wireless communication node (e.g., a gNB) that includes a first configuration (e.g., an MDT or QoE configuration) that includes an indication of an NPN range of a first measurement (e.g., an MDT or QoE measurement) to be performed by the wireless communication device.
