[0134] In the embodiments of the present disclosure, the terms "first", "second", and the like are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second" are usually of the same type and do not limit the number of objects, for example, the first object can be one or more.

[0135] The technical solutions in the embodiments of the present disclosure will be described in detail below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present disclosure.

[0136] In order to more clearly understand the technical solutions of the embodiments of the present disclosure, first, some technical contents related to the embodiments of the present disclosure are introduced.

[0137] 1. Network slice

[0138] In NR, the network can implement network slicing by scheduling and providing different configurations, and different slices correspond to different requirements. Services of different slices are processed through different PDU sessions, that is, each slice corresponds to a PDU session. Each slice is identified by S-NSSAI, and each S-NSSAI can be composed of two parts:

[0139] Mandatory SST (Slice / Service Type): identifies the type of slice;

[0140] Optional SD (Slice Differentiator): further distinguishes slices of the same SST.

[0141] The network can support hundreds of slices, but a terminal (or UE) can only support a maximum of 8 slices at the same time.

[0142] When the UE requests to access the network, the UE can include the requested slice information in the RRCSetupComplete message, and the network feeds back the allowed slice information and the rejected slice information to the UE in the subsequent downlink message.

[0143] It is generally considered that the deployment of slice is per TA, that is, the cells in a TA support the same slice. After enhancement in the related art, the service area of a specific slice is allowed to be inconsistent with the TA defined on the RAN side, that is, when a cell is in a TA but not in the service area of a slice, the cell can use the method of defining the cell to provide zero resources for the slice to represent the support of the cell for the slice, and the cell will not use any resource of the slice. Adjacent nodes also interactively configure the slice zero resource cell for UE to move and make decisions.

[0144] 2. MDT

[0145] 2.1 Immediate MDT

[0146] The measurement contents supported by the immediate MDT mainly include the following parts, some of which are UE measurements and some of which are base station measurements:

[0159] (8) M8: UE performs Received Signal Strength Indication (RSSI) measurement (for BT / WLAN measurement);

[0160] (9) M9: UE performs Round Trip Time (RTT) measurement (for WLAN measurement).

[0161] Immediate MDT measurement reporting trigger conditions:

[0162] For M1:

[0168] The measurement content supported by Logged MDT includes:

[0169] (1) Trace and absolute timestamp configuration parameters.

[0170] (2) Relative timestamp information.

[0171] (3) UE location information.

[0172] (4) Identity (ID) information of the serving cell associated with the recorded data;

[0173] (5) Measurement results of the serving cell associated with the recorded data, including:

[0185] Layer One (L1) event triggering, the L1 event means that the serving cell signal quality is lower than a specific threshold.

[0186] 2.3 Configuration range of Immediate MDT and Logged MDT

[0187] The configuration range of Immediate MDT and Logged MDT includes:

[0188] (1) Cell based: refers to that the UE only measures in some cells.

[0189] (2) TAI (Tracking Area Identity, TAI) based: refers to that the UE only measures in some TAIs.

[0190] (3) PLMN (Public Land Mobile Network, PLMN) based: refers to that the UE only measures in some PLMNs.

[0191] (4) NPN (Non-Public Network, non-public network) related based, including PNI-NPN (Public Network Integrated Non-Public Network, public network private network combination) based MDT, SNPN (Stand-alone Non-Public Network, independent non-public network) cell based MDT, SNPN TAI based MDT, SNPN based MDT.

[0192] In the related art, MDT does not support any slice-related content, which causes the network to be unable to identify the real slice deployment situation, and the UE will cause service interruption and affect performance when at a slice vulnerability or without enough slice resources. Therefore, the present disclosure provides an MDT reporting method, which enables the network to identify the real slice deployment situation to realize optimization of slice deployment.

[0193] FIG. 1 is a flowchart of an MDT reporting method provided by an embodiment of the present disclosure, which is applied to a first communication device. As shown in FIG. 1, the method comprises the following steps:

[0194] Step 100: receiving MDT configuration or indication information sent by a second communication device; the MDT configuration contains area scope information, the area scope information contains slice information, and the indication information is used to indicate the first communication device to carry the slice information when performing MDT reporting.

[0195] Specifically, the first communication device is a terminal or an access network device (for example, a base station).

[0196] In the case where the first communication device is a terminal, the second communication device is an access network device, and the terminal receives the MDT configuration or indication information sent by the access network device, the MDT configuration contains area scope information, the area scope information contains slice information (the MDT configuration is enhanced), and the indication information is used to indicate the terminal to carry the slice information when performing MDT reporting.

[0197] In a case that the first communication device is an access network device, the second communication device is a core network network element and / or an Operation Administration and Maintenance (OAM), the access network device receives MDT configuration or indication information sent by the core network network element and / or the OAM, the MDT configuration contains area range information, the area range information contains slice information, and the indication information is used to indicate that the access network device carries the slice information when performing MDT reporting. The access network device can further send the MDT configuration or the indication information to the terminal, the MDT configuration contains area range information, the area range information contains slice information, and the indication information is used to indicate that the terminal carries the slice information when performing MDT reporting.

[0198] In step 101, MDT measurement information is reported based on the MDT configuration or the indication information, and the MDT measurement information carries the slice information.

[0199] Specifically, after the first communication device receives the enhanced MDT configuration or the indication information, the first communication device can report the slice information together when reporting the MDT measurement information based on the enhanced MDT configuration or the indication information.

[0200] For example, the terminal carries the slice information in the MDT measurement information reported to the access network device.

[0201] For another example, the access network device carries the slice information in the MDT measurement information reported to the core network and / or the OAM.

[0202] The MDT reporting method provided by the embodiments of the present disclosure can send enhanced MDT configuration or indication information to the first communication device by the second communication device, and after the first communication device receives the enhanced MDT configuration or the indication information, the first communication device can report the slice information together when reporting the MDT measurement information based on the enhanced MDT configuration or the indication information, so that the network can identify the real slice deployment situation and thus realize the optimization of the slice deployment.

[0203] In some embodiments, the area range information is slice-based area range information, or the area range information is existing area range information.

[0204] Specifically, the enhancement of the MDT configuration can have different schemes. One scheme can be to define a new area scope for the slice, and the slice information is contained in the newly defined area range information for the slice. For example, a new area scope is added to the MDT configuration, the area scope is slice based, and the area scope contains slice information. The first communication device only performs measurement within the range of the slice corresponding to the slice information.

[0205] Another solution can be to include slice information in the existing area scope information, or can be understood as combining the slice with the existing area scope, adding the slice information to the existing area scope, and the first communication device only measures within the configured existing area scope and within the configured slice (the slice corresponding to the slice information) range that supports the configured slice.

[0206] For example, the MDT combined with the slice and the existing area scope can include one or more of the following: Cell based slice MDT (MDT combined with the slice and the existing cell based area scope), TAI based slice MDT (MDT combined with the slice and the existing TAI based area scope), PLMN based slice MDT (MDT combined with the slice and the existing PLMN based area scope), SNPN based slice MDT (MDT combined with the slice and the existing SNPN based area scope), PNI-NPN based slice MDT (MDT combined with the slice and the existing PNI-NPN based area scope), SNPN Cell based slice MDT (MDT combined with the slice and the existing SNPN Cell based area scope), SNPN TAI based slice MDT (MDT combined with the slice and the existing SNPN TAI based area scope).

[0207] Cell based slice MDT: The first communication device only measures within the configured cell range and within the configured slice cell that supports the configured slice.

[0208] TAI based slice MDT: The first communication device only measures within the configured TAI range and within the configured slice range that supports the configured slice.

[0209] PLMN based slice MDT: The first communication device only measures within the configured PLMN range and within the configured slice range that supports the configured slice.

[0210] SNPN based slice MDT: The first communication device only measures within the configured SNPN range and within the configured slice range that supports the configured slice.

[0211] PNI-NPN based slice MDT: The first communication device only measures within the configured PNI-NPN range and supports the configured slice range.

[0212] SNPN Cell based slice MDT: The first communication device only measures within the configured specific cell range of the SNPN and supports the configured slice range.

[0213] SNPN TAI based slice MDT: The first communication device only measures within the configured specific TAI range of the SNPN and supports the configured slice range.

[0214] By different MDT configuration enhancement methods, the flexibility of MDT configuration is improved.

[0215] In some embodiments, the MDT measurement information further carries one or more of the following:

[0216] (1) Measurement results of cells or beams supporting a specified slice.

[0217] Specifically, the specified slice refers to the slice corresponding to the slice information included in the MDT configuration, i.e., the slice configured by the network.

[0218] Supporting a cell or beam of a specified slice can also include allowing a cell or beam of a specified slice, a cell or beam available for a specified slice, and a cell or beam capable of measuring a specified slice.

[0219] The cell can be a serving cell, a neighbor cell, or a camped cell.

[0220] For example, the MDT configuration adds an area scope, which is slice based, and includes slice information slice 1. The MDT measurement information reported by the first communication device can carry measurement results of cells or beams supporting the slice 1.

[0221] For another example, the MDT configuration adds slice information in an existing area scope. Assuming it is a Cell based slice MDT, the slice information slice 1 is added in the Cell based area scope. The MDT measurement information reported by the first communication device can carry measurement results of cells or beams supporting the slice 1 within the Cell based area scope.

[0222] (2) Measurement information of a slice.

[0223] In some embodiments, the measurement information of the slice can be per-slice measurement information. For example, it can be the measurement information of each slice corresponding to the slice information contained in the MDT configuration, or it can be the measurement information of each slice supported by the cell or beam in the MDT measurement information.

[0224] By carrying more detailed slice-related information in the MDT measurement information, it is beneficial for the network to better optimize slice deployment.

[0225] In some embodiments, the measurement information of the slice includes one or more of the following:

[0226] average throughput per slice;

[0227] data volume per slice;

[0228] packet loss rate per slice;

[0229] data packet delay per slice;

[0230] zero resource cell per slice. Wherein, the zero resource cell means that the cell resource cannot be used for a certain slice.

[0231] For example, in the case where the MDT configuration contains slice information, assuming that the slice information corresponds to slice 1 and slice 2, the first communication device can report one or more of the average throughput, data volume, packet loss rate, data packet delay, and zero resource cell information of slice 1, and one or more of the average throughput, data volume, packet loss rate, data packet delay, and zero resource cell information of slice 2.

[0232] For example, if the first communication device performs MDT reporting according to the indication information sent by the second communication device, assuming that the measurement result of cell 1 is carried in the reported MDT measurement information, and the slice supported by the cell 1 is slice 1 and slice 2, the first communication device can report one or more of the average throughput, data volume, packet loss rate, data packet delay, and zero resource cell information of slice 1, and one or more of the average throughput, data volume, packet loss rate, data packet delay, and zero resource cell information of slice 2.

[0233] The measurement information of the slice includes one or more of the average throughput, data volume, packet loss rate, data packet delay, and zero resource cell information per slice, which not only improves the flexibility of MDT reporting, but also enables the network to better understand the actual situation of slice deployment, thereby facilitating the network to better optimize slice deployment.

[0234] In some embodiments, the MDT configuration configures one or more of the following measurement trigger conditions:

[0235] Layer one event trigger;

[0236] Periodic trigger;

[0237] Out of coverage trigger;

[0238] Detecting slice trigger.

[0239] Specifically, for the enhanced scheme that the slice information is contained in the MDT configuration, in addition to the existing measurement trigger conditions (L1 event trigger, periodic trigger, out of coverage trigger), the disclosure also introduces a new measurement trigger condition, i.e., detecting slice trigger. For example, the first communication device detects that a specific cell (such as a serving cell, a current UE camped cell, etc.) supports a specified slice, and then triggers measurement reporting (or logging).

[0240] The MDT in the disclosure can be Immediate MDT and / or Logged MDT, without limitation.

[0241] By introducing the slice-related measurement trigger condition, the MDT can more effectively report the slice-related content, thereby facilitating the network to better optimize the slice deployment.

[0242] In some embodiments, the MDT configuration configures one or more of the following measurement contents:

[0243] Measurement results of a cell or a beam supporting a specified slice;

[0244] Measurement information of a slice.

[0245] Specifically, the second communication device can configure the first communication device with slice-related measurement content, and the first communication device performs measurement and reporting according to the configured measurement content. For example, the first communication device measures and reports the measurement results of a cell or a beam supporting a specified slice according to the configured measurement content, or measures and reports the measurement information of a slice according to the configured measurement content. The measurement information of a slice includes at least one of the following information: average throughput per slice, data volume per slice, packet loss rate per slice, data packet delay per slice, and zero resource cell per slice.

[0246] By configuring the slice-related measurement content, the first communication device can more effectively perform slice-related measurement and reporting, thereby facilitating the network to better optimize the slice deployment.

[0247] In some embodiments, the slice information includes one or more of the following: S-NSSAI, NSAG identifier, and NSAG slice support list (i.e., a list of slices supported by the NSAG, including a list of slices belonging to the NSAG).

[0248] For example, the first communication device receives the MDT configuration sent by the second communication device, and the area range information of the MDT configuration includes slice information, which can be one or more of S-NSSAI, NSAG identifier, and NSAG slice support list. The one or more slice information can be used to identify or indicate a specific slice, and the first communication device can determine the slice configured by the network through the one or more slice information.

[0249] For another example, the MDT measurement information reported by the first communication device carries slice information, which can be one or more of S-NSSAI, NSAG identifier, and NSAG slice support list. The network can determine which slice information is included in the MDT measurement information reported by the first communication device according to the one or more slice information.

[0250] In some embodiments, the slice information can be a list, which includes a plurality of S-NSSAI, NSAG ID, or NSAG slice support list.

[0251] For the slice information in the MDT configuration and the slice information carried in the MDT measurement information, the identification or indication of the slice is performed through one or more of S-NSSAI, NSAG identifier, and NSAG slice support list. The MDT configuration and MDT reporting can have higher flexibility.

[0252] FIG. 2 is a flowchart of a method for MDT reporting provided by an embodiment of the present disclosure, which is applied to a second communication device. As shown in FIG. 2, the method includes the following steps:

[0253] In step 200, MDT configuration or indication information is sent to a first communication device. The MDT configuration includes area range information, and the area range information includes slice information. The indication information is used to indicate that the first communication device carries slice information when performing MDT reporting.

[0254] In step 201, MDT measurement information reported by the first communication device is received, and the MDT measurement information carries slice information.

[0255] Specifically, the first communication device is a terminal or an access network device (for example, a base station).

[0256] In a case that the first communication device is a terminal, the second communication device is an access network device, and the terminal receives MDT configuration or indication information sent by the access network device, the MDT configuration contains area scope information, and the area scope information contains slice information (the MDT configuration is enhanced), and the indication information is used to indicate the terminal to carry the slice information when performing MDT reporting.

[0257] In a case that the first communication device is an access network device, the second communication device is a core network element and / or OAM, and the access network device receives MDT configuration or indication information sent by the core network element and / or OAM, the MDT configuration contains area scope information, and the area scope information contains slice information, and the indication information is used to indicate the access network device to carry the slice information when performing MDT reporting. The access network device can further send MDT configuration or indication information to the terminal, the MDT configuration contains area scope information, and the area scope information contains slice information, and the indication information is used to indicate the terminal to carry the slice information when performing MDT reporting.

[0258] After the first communication device receives the enhanced MDT configuration or indication information, the first communication device can report the slice information together with MDT measurement information based on the enhanced MDT configuration or the indication information.

[0259] For example, the terminal carries the slice information in the MDT measurement information reported to the access network device.

[0260] For another example, the access network device carries the slice information in the MDT measurement information reported to the core network and / or OAM.

[0261] The MDT reporting method provided by the embodiments of the present disclosure can send enhanced MDT configuration or indication information to the first communication device by the second communication device, and after the first communication device receives the enhanced MDT configuration or the indication information, the first communication device can report the slice information together with MDT measurement information based on the enhanced MDT configuration or the indication information, so that the network can identify the real slice deployment situation and thus optimize the slice deployment.

[0262] In some embodiments, the area scope information is slice based area scope information, or the area scope information is existing area scope information.

[0263] Specifically, the enhancement of the MDT configuration can have different schemes. One scheme can be to define a new area scope for the slice, and the slice information is contained in the newly defined area scope information for the slice. For example, the MDT configuration adds an area scope, and the area scope is slice based, which contains slice information, and the first communication device only performs measurement within the range of the slice corresponding to the slice information.

[0264] Another solution can be to include slice information in the existing area scope information, or can be understood as combining the slice with the existing area scope, adding the slice information to the existing area scope, and the first communication device only measures within the configured existing area scope and within the configured slice (the slice corresponding to the slice information) range that supports the configured slice.

[0265] For example, the MDT combined with the slice and the existing area scope can include one or more of the following: Cell based slice MDT (MDT combined with the slice and the existing cell based area scope), TAI based slice MDT (MDT combined with the slice and the existing TAI based area scope), PLMN based slice MDT (MDT combined with the slice and the existing PLMN based area scope), SNPN based slice MDT (MDT combined with the slice and the existing SNPN based area scope), PNI-NPN based slice MDT (MDT combined with the slice and the existing PNI-NPN based area scope), SNPN Cell based slice MDT (MDT combined with the slice and the existing SNPN Cell based area scope), SNPN TAI based slice MDT (MDT combined with the slice and the existing SNPN TAI based area scope).

[0266] Cell based slice MDT: The first communication device only measures within the configured cell range and within the configured slice cell that supports the configured slice.

[0267] TAI based slice MDT: The first communication device only measures within the configured TAI range and within the configured slice range that supports the configured slice.

[0268] PLMN based slice MDT: The first communication device only measures within the configured PLMN range and within the configured slice range that supports the configured slice.

[0269] SNPN based slice MDT: The first communication device only measures within the configured SNPN range and within the configured slice range that supports the configured slice.

[0270] PNI-NPN based slice MDT: The first communication device only measures within the configured PNI-NPN range and within the configured slice range.

[0271] SNPN Cell based slice MDT: The first communication device only measures within the configured SNPN specific cell range and within the configured slice range.

[0272] SNPN TAI based slice MDT: The first communication device only measures within the configured SNPN specific TAI range and within the configured slice range.

[0273] By different MDT configuration enhancement ways, the flexibility of MDT configuration is improved.

[0274] In some embodiments, the MDT measurement information further carries one or more of the following:

[0275] (1) Measurement results of cells or beams supporting a specified slice.

[0276] Specifically, the specified slice refers to a slice corresponding to the slice information included in the MDT configuration, i.e., a network-configured slice.

[0277] Supporting a specified slice of a cell or beam can also include allowing a specified slice of a cell or beam, a specified slice of an available cell or beam, a specified slice of a measurable cell or beam, etc.

[0278] The cell can be a serving cell, a neighbor cell, or a camped cell.

[0279] For example, the MDT configuration adds an area scope, which is slice based, and includes slice information slice 1. The MDT measurement information reported by the first communication device can carry measurement results of cells or beams supporting the slice 1.

[0280] For another example, the MDT configuration adds slice information in an existing area scope. Assuming it is a Cell based slice MDT, the slice information slice 1 is added in the Cell based area scope. The MDT measurement information reported by the first communication device can carry measurement results of cells or beams supporting the slice 1 within the Cell based area scope.

[0281] (2) Measurement information of a slice.

[0282] In some embodiments, the measurement information of the slice can be per-slice measurement information. For example, it can be the measurement information of each slice corresponding to the slice information contained in the MDT configuration, or it can be the measurement information of each slice supported by the cell or beam in the MDT measurement information.

[0283] By carrying more detailed slice-related information in the MDT measurement information, it is beneficial for the network to better optimize slice deployment.

[0284] In some embodiments, the measurement information of the slice includes one or more of the following:

[0285] average throughput per slice;

[0286] data volume per slice;

[0287] packet loss rate per slice;

[0288] data packet delay per slice;

[0289] zero resource cell per slice. Wherein, the zero resource cell means that the cell resource cannot be used for a certain slice.

[0290] For example, in the case where the MDT configuration contains slice information, assuming that the slice information corresponds to slice 1 and slice 2, the first communication device can report one or more of the average throughput, data volume, packet loss rate, data packet delay, and zero resource cell information of slice 1, and one or more of the average throughput, data volume, packet loss rate, data packet delay, and zero resource cell information of slice 2.

[0291] For example, if the first communication device performs MDT reporting according to the indication information sent by the second communication device, assuming that the measurement result of cell 1 is carried in the reported MDT measurement information, and the slice supported by the cell 1 is slice 1 and slice 2, the first communication device can report one or more of the average throughput, data volume, packet loss rate, data packet delay, and zero resource cell information of slice 1, and one or more of the average throughput, data volume, packet loss rate, data packet delay, and zero resource cell information of slice 2.

[0292] The measurement information of the slice includes one or more of the average throughput, data volume, packet loss rate, data packet delay, and zero resource cell information per slice, which not only improves the flexibility of MDT reporting, but also enables the network to better understand the actual situation of slice deployment, thereby facilitating the network to better optimize slice deployment.

[0293] In some embodiments, the MDT configuration configures one or more of the following measurement trigger conditions:

[0294] Layer one event trigger;

[0295] Periodic trigger;

[0296] Out-of-coverage trigger;

[0297] Detecting slice trigger.

[0298] Specifically, for the enhanced scheme that the slice information is included in the MDT configuration, in addition to the existing measurement trigger conditions (L1 event trigger, periodic trigger, out-of-coverage trigger), the disclosure also introduces a new measurement trigger condition, i.e., detecting slice trigger. For example, the first communication device detects that a specific cell (such as a serving cell, a current UE camped cell, etc.) supports a specified slice, and then triggers measurement reporting (or logging).

[0299] By introducing the slice-related measurement trigger condition, the MDT can more effectively report the slice-related content, thereby facilitating the network to better optimize the slice deployment.

[0300] In some embodiments, the MDT configuration configures one or more of the following measurement contents:

[0301] Measurement results of a cell or a beam supporting a specified slice;

[0302] Measurement information of a slice.

[0303] Specifically, the second communication device can configure the first communication device with slice-related measurement content, and the first communication device performs measurement and reporting according to the configured measurement content. For example, the first communication device measures and reports the measurement results of a cell or a beam supporting a specified slice according to the configured measurement content, or measures and reports the measurement information of a slice according to the configured measurement content. The measurement information of a slice includes at least one of the following information: average throughput per slice, data volume per slice, packet loss rate per slice, data packet delay per slice, and zero-resource cell per slice.

[0304] By configuring the slice-related measurement content, the first communication device can more effectively perform slice-related measurement reporting, thereby facilitating the network to better optimize the slice deployment.

[0305] In some embodiments, the above-mentioned slice information includes one or more of the following: S-NSSAI; NSAG identifier; and NSAG slice support list (i.e., a list of slices supported by the NSAG, including a list of slices belonging to the NSAG).

[0306] For example, the first communication device receives the MDT configuration sent by the second communication device, and the slice information in the area scope information of the MDT configuration can be one or more of S-NSSAI, NSAG identifier, and NSAG slice support list, which can be used to identify or indicate a specific slice, and the first communication device can determine the slice configured by the network through the one or more slice information.

[0307] For another example, the MDT measurement information reported by the first communication device carries slice information, which can be one or more of S-NSSAI, NSAG identifier, and NSAG slice support list, and the network can determine which slice information is included in the MDT measurement information reported by the first communication device according to the one or more slice information.

[0308] In some embodiments, the above slice information can be a list containing a plurality of S-NSSAI, NSAG ID, or NSAG slice support list.

[0309] For the slice information in the MDT configuration and the slice information carried in the MDT measurement information, the identification or indication of the slice is performed through one or more of S-NSSAI, NSAG identifier, and NSAG slice support list, and the MDT configuration and MDT reporting can have higher flexibility.

[0310] The methods provided by the embodiments of the present disclosure are based on the same application concept, and the implementation of each method can be referred to each other, and the repeated parts will not be described again.

[0311] The methods provided by the above-mentioned embodiments of the present disclosure are exemplified below through specific application scenarios.

[0312] Example 1: Defining a new area scope of MDT for a slice.

[0313] The core network and / or OAM sends the MDT configuration to the base station, and the base station can further send the MDT configuration to the UE (through RRC message, dedicated signaling, system information block (SIB), etc.), and the MDT configuration includes at least one of the following: area scope information of MDT, measurement trigger condition of the UE and / or base station, and content that needs to be measured by the UE and / or base station.

[0314] When the area scope information sent by the core network and / or OAM to the base station is “based on slice”, the slice information is included. Specifically, a new area scope is added, which is slice based, and contains slice information.

[0315] The slice information includes one or more of the following: S-NSSAI, NSAG ID, NSAG slice support list (including the list of slices belonging to the NSAG). The slice information can be a list containing multiple S-NSSAI, NSAG ID, and NSAG slice support list.

[0316] The UE and / or the base station only perform measurements within the scope of the slice (the slice corresponding to the slice information) configured.

[0317] For example, the core network and / or OAM configures the base station with an area scope of slice 1, and the base station further sends the configuration to the UE. Then, the UE and / or the base station only consider performing MDT when slice 1 can be measured.

[0318] The measurement triggering condition for the UE and / or the base station to perform MDT can be that the core network and / or OAM configures the base station with a measurement triggering condition, and the base station further sends the configuration information to the UE. The measurement triggering condition includes: L1 event triggering, periodic triggering, out-of-coverage triggering, and detection of a slice trigger.

[0319] For example, if the UE and / or the base station monitor that a specific cell supports the slice that needs to be measured (the specific cell can be interpreted as the serving cell and / or the current UE camping cell), the UE and / or the base station perform measurement reporting (or logging); or if the UE and / or the base station monitor that a specific cell supports the slice that needs to be measured (the specific cell can be interpreted as the serving cell and / or the current UE camping cell), and the L1 event / periodic / out-of-coverage triggering condition is met, the UE and / or the base station perform measurement reporting (logging).

[0320] The core network and / or OAM also sends the measurement content to the base station, i.e., the measurement content that needs to be collected by the base station / UE, which can be further sent to the UE by the base station.

[0321] The measurement content includes one or more of the following: Immediate MDT measurement quantity, Logged MDT measurement quantity, measurement result of the cell / beams supporting the slice (the slice corresponding to the slice information), per slice average throughput, per slice data volume, per slice packet loss rate, per slice packet delay, and per slice zero-resource cell.

[0322] When the UE and / or the base station reports MDT, it carries the measurement-related information and the slice information that the core network and / or OAM wants it to measure.

[0323] The measurement-related information includes at least one of the following: a measured Immediate MDT measurement quantity, a measured Logged MDT measurement quantity, a measurement result of a cell / wave beam supporting the slice, a per-slice average throughput, a per-slice data quantity, a per-slice packet loss rate, a per-slice packet delay, and a per-slice zero resource cell.

[0324] The slice information is slice information set for an area scope.

[0325] For example, the core network and / or OAM configure the base station with an area scope of slice 1, and the base station further sends the configuration to the UE, so that the UE and / or the base station should report the slice 1 measurement-related information and the slice 1 slice information.

[0326] Example 2: Adding slice information based on an existing area scope.

[0327] The core network and / or OAM send an MDT configuration to the base station, and the base station can further send the MDT configuration to the UE (through an RRC message, dedicated signaling, an SIB, etc.), and the MDT configuration includes at least one of the following: area scope information of MDT, measurement triggering conditions of the UE and / or the base station, and content to be measured by the UE and / or the base station.

[0328] When the area scope information is cell based slice MDT, the core network and / or OAM need to send slice information in addition to the cell ID contained in the cell based area scope to the base station.

[0329] The slice information includes one or more of the following: S-NSSAI, NSAG ID, and NSAG slice support list (including a list of slices belonging to the NSAG). The slice information can be a list containing multiple S-NSSAI, NSAG ID, and NSAG slice support list.

[0330] The UE and / or the base station only perform measurement on cells within the configured cell range and supporting the configured slice.

[0331] For example, the core network and / or OAM configure the base station with an area scope of cell based slice MDT, specifically cell 1-10 and slice 1, and the base station further sends the configuration to the UE, so that the UE and / or the base station only consider performing MDT on slice 1 within cell 1-10.

[0332] The measurement triggering condition for the UE and / or the base station to perform MDT can be that the core network and / or OAM configures the measurement triggering condition to the base station, the base station further sends the configuration information to the UE, and the measurement triggering condition includes: L1 event triggering, periodic triggering, and out-of-coverage triggering.

[0333] For example, if the UE and / or the base station monitor that a specific cell supports a slice that needs to be measured (the specific cell can be interpreted as a serving cell and / or a current UE camping cell), and the triggering condition of the L1 event / periodic / out-of-coverage is met, the UE and / or the base station perform measurement logging.

[0334] The core network / OAM also sends the measurement content, i.e., the measurement content that needs to be collected by the base station / UE, to the base station, which can further send it to the UE.

[0335] The measurement content includes one or more of the following: Immediate MDT measurement quantity, Logged MDT measurement quantity, measurement result of a cell / beam supporting the slice (slice information corresponds to the slice), per slice average throughput, per slice data volume, per slice packet loss rate, per slice packet delay, and per slice zero resource cell.

[0336] When the UE and / or the base station performs MDT logging, it carries the measurement-related information and the slice information that the core network and / or OAM wants it to measure.

[0337] The measurement-related information includes at least one of the following: Immediate MDT measurement quantity, Logged MDT measurement quantity, measurement result of a cell / beam supporting the slice (slice information corresponds to the slice), per slice average throughput, per slice data volume, per slice packet loss rate, per slice packet delay, and per slice zero resource cell measured in the cell area scope (configured cell range).

[0338] Note: Similar for other granularity area scopes, which will not be repeated. For example, for a TAI-based area scope, it is: report the measured Immediate MDT measurement quantity, Logged MDT measurement quantity, measurement result of a cell / beam supporting the slice (slice information corresponds to the slice), per slice average throughput, per slice data volume, per slice packet loss rate, per slice packet delay, and per slice zero resource cell in the TAI area scope (configured TAI range).

[0339] The slice information is the slice information contained in the cell based area scope.

[0340] For example, the core network and / or OAM configures the area scope of the base station as cell 1-10 and slice 1, and the base station further sends the configuration to the UE. Then the UE and / or the base station should report the slice 1 measurement related information and slice 1 slice information that can be measured in cell 1-10.

[0341] For other granularity, refer to the cell based slice MDT, the difference is:

[0342] TAI based slice MDT: According to the configuration of the core network and / or OAM, the UE / base station only measures within the configured TAI range and supports the configured slice range.

[0343] PLMN based slice MDT: According to the configuration of the core network and / or OAM, the UE / base station only measures within the configured PLMN range and supports the configured slice range.

[0344] SNPN based slice MDT: According to the configuration of the core network and / or OAM, the UE / base station only measures within the configured SNPN range and supports the configured slice range.

[0345] PNI-NPN based slice MDT: According to the configuration of the core network and / or OAM, the UE / base station only measures within the configured PNI-NPN range and supports the configured slice range.

[0346] SNPN Cell based slice MDT: According to the configuration of the core network and / or OAM, the UE / base station only measures within the configured specific cell range of the SNPN and supports the configured slice range.

[0347] SNPN TAI based slice MDT: According to the configuration of the core network and / or OAM, the UE / base station only measures within the configured specific TAI range of the SNPN and supports the configured slice range.

[0348] Example 3: Send indication information.

[0349] The core network and / or OAM sends MDT configuration to the base station, which can further send the MDT configuration to the UE (through RRC message, dedicated signaling, SIB, etc.), the MDT configuration including at least one of: area scope information of MDT, measurement triggering condition of the UE and / or the base station, and content to be measured by the UE and / or the base station. (For example 3, the area scope information of MDT is not enhanced, and the existing mechanism is used, i.e., the UE performs measurement within the configured area scope. The measurement triggering condition of the UE and / or the base station is also not enhanced, and the existing mechanism is used.)

[0350] The core network and / or OAM sends indication information to the base station, which is used to indicate that the UE and / or the base station carries slice information when performing MDT reporting. The base station sends the indication information to the UE, which is used to indicate that the UE carries slice information when performing MDT reporting.

[0351] The slice information includes one or more of: S-NSSAI, NSAG ID, and NSAG slice support list (including a list of slices belonging to the NSAG). The slice information can be a list containing multiple S-NSSAI, NSAG ID, and NSAG slice support list.

[0352] The core network and / or OAM also sends measurement content to the base station, i.e., the measurement content to be collected by the base station / UE, which can be further sent to the UE by the base station.

[0353] The measurement content includes one or more of: Immediate MDT measurement quantity, Logged MDT measurement quantity, per slice average throughput, per slice data volume, per slice packet loss rate, per slice packet delay, and per slice zero resource cell.

[0354] The UE and / or the base station carries measurement-related information and slice information when performing MDT reporting.

[0355] The measurement-related information includes at least one of: measured Immediate MDT measurement quantity, measured Logged MDT measurement quantity, per slice average throughput, per slice data volume, per slice packet loss rate, per slice packet delay, and per slice zero resource cell.

[0356] The slice information is the slice information corresponding to the measurement-related information.

[0357] For example, the core network and / or OAM indicates to the base station to let the base station and / or UE carry slice information when reporting MDT, and the base station further sends the indication to the UE. The UE and / or base station need to carry the slice information supported by the cell / the beam when reporting the cell / beam measurement result, such as cell 1 + the slice 1, 2, 3 supported by the cell + measurement result. When the UE and / or base station report per DRB throughput, it is per UE per slice for DL, and the UE reports per slice throughput, such as how much is the throughput of slice 1 of the UE, how much is the throughput of slice 2 of the UE, and it is per DRB per UE per slice for UL, and the UE reports per DRB per slice throughput, such as the throughput of DRB1 and the slice information slice 1 used by the DRB1, the throughput of DRB2 and the slice information used by the DRB2, and so on. The reporting of other measurement quantities is the same, and details are not described herein.

[0358] The method and device provided by the embodiments of the present disclosure are based on the same application concept, and the implementation of the device and the method can be referred to each other because the principles of the method and the device for solving problems are similar, and details are not described herein.

[0360] The memory 320 is configured to store a computer program; and the transceiver 310 is configured to transceive data under the control of the processor 300.

[0361] Specifically, the transceiver 310 is configured to receive and send data under the control of the processor 300.

[0362] In FIG. 3, the bus architecture can include any number of interconnected buses and bridges, and various circuits of the one or more processors represented by the processor 300 and the memory represented by the memory 320 are linked together. The bus architecture can also link various other circuits such as peripheral devices, voltage stabilizers and power management circuits, which are well known in the art, and therefore, the present disclosure will not further describe them. The bus interface provides an interface. The transceiver 310 can be multiple elements, that is, it includes a transmitter and a receiver, and provides a unit for communicating with various other devices on a transmission medium, including wireless channels, wired channels, optical cables and other transmission media.

[0363] The processor 300 is responsible for managing the bus architecture and general processing, and the memory 320 can store data used by the processor 300 when performing operations.

[0364] The processor 300 can be a central processing unit (CPU), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or a complex programmable logic device (CPLD), and the processor can also adopt a multi-core architecture.

[0365] The processor 300 invokes the computer program stored in the memory 320 to execute any of the methods provided by the embodiments of the present disclosure according to the obtained executable instructions, for example:
