According to the embodiment of the application, whether the management-based Logged MDT is configured to the UE is determined by receiving the indication information sent by the second network equipment according to the indication information, so that the situation that the possible management-based Logged MDT configuration covers the signaling-based Logged MDT configuration is avoided.

Description

Method and device for processing drive test information

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for processing drive test information.

Background

Minimization of Drive-Test (MDT) configuration reuse the traceroute mechanism and makes necessary extensions. The Trace function is originally used to track the calling process of User Equipment (UE), and each network element collects the session information of the UE and reports the session information to a dedicated entity for analysis. After the Trace is extended, MDT configuration and UE measurement data collection may be supported.

The Logged MDT inherits two configuration types for Trace, including management/area based (management/area based) and signaling based (signaling based) types. The configuration of the UE side for a single network node can only simultaneously store one set of Logged MDT configuration. After the two sets of configurations are successively sent to the UE, the configuration based on the signaling is allowed to cover the configuration based on the management, but the MDT configuration based on the management is not allowed to cover the MDT configuration based on the signaling.

If the UE does not directly enter an IDLE/INACTIVE state to perform the Logged MDT measurement after receiving the Logged MDT configuration, switching or wireless link failure occurs; or cell reconstruction after failure; or the UE is switched to other network nodes without reporting the Logged MDT measurement result after entering the connected state from the IDLE/INACTIVE state. Generally, a network side node newly accessed by the UE performs Logged MDT configuration for the UE, and in this configuration process, the newly accessed network side node may configure management-based MDT configuration for the UE, but the UE may discard the management-based MDT configuration according to the above principle, which not only wastes network resources, but also reduces system processing efficiency.

Detailed Description

In the embodiment of the present application, the term "and/or" describes an association relationship of associated objects, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

The MDT configuration reuses the traceroute mechanism and makes necessary extensions. The Trace function is originally used for tracking the calling process of the UE, and each network element collects the session information of the UE and reports the session information to a special entity for analysis. After the Trace is extended, MDT configuration and UE measurement data collection may be supported.

The Logged MDT inherits two configuration types of Trace and carries out air interface expansion. The two configuration types are:

management/area based (management/area based) configuration. The method is used for monitoring the coverage strength and quality in a certain area. The base station may select any subscribed UE to send the MDT configuration. The configuration parameters of the MDT configuration are directly sent to the base station by the management node of the core network, and the base station is configured to the UE. The management-based MDT configuration parameters are not passed between network elements.

Signaling based (signaling based) configuration. For signal strength and quality monitoring for a single UE. The base station transmits the MDT configuration only to the designated UE. The core network management node forwards the MDT configuration to the base station through signaling interfaces between different network elements, and the MDT configuration is sent to the UE after the MDT configuration is received by the base station.

The MDT configuration of the UE side for a single network node only can simultaneously store one set of Logged MDT configuration. After the two sets of configurations are successively sent to the UE, the configuration based on the signaling is allowed to cover the configuration based on the management, but the MDT configuration based on the management is not allowed to cover the MDT configuration based on the signaling.

The current configuration of the Logged MDT does not require any context information to be transferred between base stations, regardless of which configuration type is used. That is, after the base station sends the Logged MDT configuration to the UE, the configuration information may be deleted. The Logged MDT configuration information includes a complete set of configuration content, and after the subsequent UE performs actual measurement and recording, the Logged MDT configuration information sends the MDT measurement result together with the complete set of configuration content to the network side, so that the network side can determine specific parameters of the MDT configuration used by the measurement result reported by the UE.

Currently, the protocol specifies that management-based MDT configuration types are not allowed to override signaling-based MDT configuration types. However, in practical application, assuming that the UE receives a signaled Logged MDT configuration from the network node a, the UE enters an IDLE/INACTIVE state to perform Logged MDT measurement; after the subsequent UE enters the connected state, the network node B accesses the network node B, and the network node B can only know whether the UE stores the Logged MDT measurement result (available indicator) through a Radio Resource Control (RRC) connection establishment/recovery/reestablishment/reconfiguration completion message, but cannot know the following information: whether the measurement result is management-based or signaling-based MDT measurement result; and whether the Logged MDT measurement currently at the UE has ended.

Therefore, after the UE accesses the network node B, if the network node B configures the UE with the managed Logged MDT measurement, it cannot be guaranteed that the protocol specification of "the managed MDT configuration is not allowed to cover the signaling MDT configuration" is specified on the UE side.

In order to solve the above problem, a scheme is proposed after the UE returns to the connected state from the IDLE/INACTIVE state:

on one hand, the UE carries the current configuration in the Logged MDT configuration, wherein the current configuration is based on signaling or management;

on the other hand, the UE notifies whether MDT measurement under the current configuration is finished or not at RRC connection establishment/restoration, and notifies whether the current MDT measurement is signaling-based or management-based/whether the signaling-based Logged MDT configuration is saved by the current UE or not.

Based on this, when receiving the RRC connection establishment/recovery completion message, the network node B may know whether the MDT configuration and/or result saved by the current UE is signaling-based, and whether Logged MDT measurement of the current UE has ended.

However, the above solution solves the problem how to inform the network side whether the current Logged MDT is signaling-based or not when the UE actually enters the IDLE state IDLE/INACTIVE state INACTIVE to perform the Logged MDT measurement and then enters the connected state, so as to avoid that the network side configures the management-based Logged MDT for the UE and violates the protocol rule. However, if the UE does not directly enter the IDLE/INACTIVE state to perform the Logged MDT measurement after receiving the Logged MDT configuration, a handover or radio link failure occurs, or a subsequent reestablishment is performed after the handover or radio link failure occurs; or the UE is switched to other network nodes without reporting the Logged MDT result after entering the connected state from the IDLE/INACTIVE state, and at this time, a network side node to which the UE is newly accessed cannot know whether the UE stores the MDT configuration and whether the configuration is not allowed to be covered by the configuration based on management based on signaling.

Under the condition that the MDT stored in the UE is configured to the signaling-based configuration, a newly accessed network side node does not know the condition and may configure a Logged MDT based on management for the UE, and under the condition, the UE is regulated according to a protocol and does not use the Logged MDT based on management and sent by the newly accessed network side node to cover the previous Logged MDT based on signaling, so that the newly accessed network side node unnecessarily configures signaling to send, and system resources are wasted.

Embodiments of the present application provide a method for processing drive test information on a network side, so that a network node newly accessed by a UE can know whether a current UE stores signaling-based Logged MDT configuration information and/or a measurement result, and accordingly, determine whether to allow the UE to be configured with a management-based Logged MDT, thereby avoiding a rule violation situation that a possible management-based MDT configuration covers the signaling-based MDT configuration.

The present application is described in detail below with reference to various embodiments.

Fig. 1 is a schematic flow chart of a method for processing drive test information according to an embodiment of the present application, and as shown in fig. 1, the method is applied to a first network device, and includes the following steps:

step 100, receiving indication information sent by a second network device, where the indication information is used to characterize a configuration type of a minimization of drive test, logged MDT, of a user equipment UE;

the MDT technology mainly obtains parameters required for network optimization by measuring and reporting a measurement result by the UE, and in the UE measurement process, network equipment that establishes communication connection with the UE may change, for example, the network equipment may be triggered to switch by the movement of the UE. The second network device in this embodiment refers to a network device connected to the UE before the communication connection change occurs, and the second network device stores MDT configuration information of the UE. The first network device in this embodiment refers to a network device that establishes a connection with the UE after a communication connection change occurs or a network device that the UE selects as a target device to connect after the communication connection change occurs.

The method comprises the steps that a first network device receives indication information sent by a second network device, and the indication information can be used for representing the configuration type of the minimization of drive test (Logged MDT) of User Equipment (UE).

It is understood that the UE herein is the same UE as the UE with the changed communication connection, and the UE may also be referred to as a current UE. The indication information is obtained based on MDT configuration information of the UE saved by the second network device, and may include indication information indicating whether the current UE saves the Logged MDT configuration based on signaling and/or indication information indicating whether the current UE saves the Logged MDT measurement result based on signaling.

And step 110, determining whether to configure a management-based Logged MDT to the UE according to the indication information.

The communication protocol specifies that the management-based MDT configuration type is not allowed to override the signaling-based MDT configuration type. The first network equipment determines whether to configure management-based Logged MDT for the UE according to the configuration type of the Logged MDT of the UE, which is characterized by the indication information, so that the condition that protocol regulations are violated can be avoided. For example, in a case that the indication information characterizes the Logged MDT configuration type of the UE is management-based, or in a case that the indication information characterizes the UE is not configured with MDT, the UE may be configured with a management-based Logged MDT, that is, the UE may be configured as a candidate UE for managing the Logged MDT as the first network device; and in the case that the indication information represents that the Logged MDT configuration type of the UE is based on the signaling, not configuring the management-based Logged MDT to the UE.

In the embodiment of the application, the first network device can receive the indication information from the second network device, and judge whether to allow the management-based Logged MDT to be configured for the current UE according to the indication information, thereby effectively avoiding a possible rule violation situation that the management-based MDT configuration covers the signaling-based MDT configuration.

Optionally, determining whether to configure a management-based Logged MDT to the UE according to the indication information includes:

After the first network device receives the indication information sent by the second network device, because the indication information may include indication information used for indicating whether the current UE stores the Logged MDT configuration based on the signaling and/or indication information used for indicating whether the current UE stores the Logged MDT measurement result based on the signaling, the first network device may know whether the current UE stores the Logged MDT configuration information based on the signaling and/or the measurement result based on the indication information, thereby knowing whether the configuration type of the Logged MDT for the minimization of drive test of the UE is signaling-based.

The first network device does not configure a management-based Logged MDT to the UE, i.e., the UE is not a candidate UE for the first network device to configure the management-based Logged MDT, if it is determined that the Logged MDT configuration of the UE is signaling-based.

Optionally, the determining not to configure the UE with a management-based Logged MDT includes:

determining a user equipment list configured with the managed Logged MDT, wherein the user equipment list does not contain the identification of the UE configured with the signaling-based Logged MDT.

Specifically, the identity of the UE is used to indicate the UE. The user equipment list refers to a set of identities of candidate UEs that can configure the managed Logged MDT. It is understood that there may be one or more candidate UEs in the user equipment list, and the first network device selects a candidate UE in the user equipment list as needed, and configures the management-based Logged MDT for the selected UE.

And the first network equipment determines a user equipment list based on the managed Logged MDT according to the indication information. And if the configuration type of the minimum drive test (Logged MDT) of the current UE is based on the signaling, not allowing the current UE to be configured with the Logged MDT based on management, and excluding the identifier of the current UE from the user equipment list.

In the embodiment of the application, the first network device can receive the indication information from the second network device, and configure the Logged MDT based user equipment list according to the indication information, thereby effectively avoiding the possible rule violation situation that the MDT configuration type based on management covers the MDT configuration type based on signaling.

Optionally, the indication information includes any one or more of:

For the case that the indication information is first indication information indicating whether the UE is configured with the Logged MDT, and whether the MDT configuration of the UE is second indication information based on signaling, in this embodiment, the indication information may include the first indication information and the second indication information, where the first indication information is whether the UE is configured with the Logged MDT, and may indicate whether the UE is configured with the Logged MDT by using specific data, for example, indicating whether the UE is configured with the Logged MDT by using 1bit identification data; the second indication information indicates whether the MDT configuration of the UE is signaling-based, and may indicate whether the MDT configuration of the UE is signaling-based through specific data, for example, indicate whether the MDT configuration of the UE is signaling-based using 1-bit identification data. If the first indication information identification data is 1, it indicates that the UE is configured with the Logged MDT, and the second indication information identification data is 1, it indicates that the MDT of the UE is configured based on signaling, and if the first indication information is 1 and the second indication information is 1, it may be determined that the configuration type of the Logged MDT of the current minimization of drive test of the UE is signaling-based.

For the case that the indication information indicates whether the configuration type of the Logged MDT stored by the UE is the third indication information based on the signaling, it may be represented by specific data whether the configuration type of the Logged MDT stored by the UE is based on the signaling, for example, it may be represented by using 1-bit identification data whether the configuration type of the Logged MDT stored by the UE is based on the signaling. If the third indication information identification data indicates that the configuration type of the Logged MDT stored by the UE is signaling-based when the third indication information identification data is 1, it may be determined that the configuration type of the Logged MDT of the current UE is signaling-based when the third indication information is 1.

For the case that the indication information is the fourth indication information indicating whether the Logged MDT measurement result is stored in the UE, and whether the MDT measurement result of the UE is the fifth indication information based on the signaling, the indication information in the embodiment of the present application may include the fourth indication information and the fifth indication information.

The fourth indication information is whether the UE stores the Logged MDT measurement result, and may indicate whether the UE stores the Logged MDT measurement result through specific data, for example, whether the UE stores the Logged MDT measurement result is indicated by using 1-bit identification data.

The fifth indication information is whether the MDT measurement result of the UE is signaling-based, and after the UE performs actual measurement recording, the UE sends the measurement result together with the complete set of configuration information to the network device, so that the network device understands specific parameters of the configuration information used by the measurement result reported by the UE, and therefore the MDT measurement result further includes all the configuration information, and the configuration information includes a configuration type, that is, the MDT measurement result can be divided into a signaling-based measurement result and a management-based measurement result. The fifth indication information may indicate whether the MDT measurement result of the UE is signaling-based through specific data, for example, whether the MDT measurement result of the UE is signaling-based using 1-bit identification data. If the fourth indication information identification data is 1, indicating that the Logged MDT measurement result is stored in the UE, and the fifth indication information identification data is 1, indicating that the MDT measurement result of the UE is signaling-based, if the fourth indication information is 1 and the fifth indication information is 1, it may be determined that the configuration type of the Logged MDT for the minimization drive test of the current UE is signaling-based.

For the case that the indication information is the sixth indication information based on the signaling, the Logged MDT measurement result further includes all configuration information, and the configuration information includes a configuration type, that is, the Logged MDT measurement result may be divided into a signaling-based measurement result and a management-based measurement result according to the configuration type. The sixth indication information may indicate whether the measurement result of the Logged MDT saved by the UE is signaling-based through specific data, for example, 1bit identification data is used to indicate whether the measurement result of the Logged MDT saved by the UE is signaling-based. If the sixth indication information identification data is 1, it indicates that the measurement result of the Logged MDT stored by the UE is based on signaling, and if the sixth indication information is 1, it may be determined that the configuration type of the Logged MDT for the minimization of drive test of the current UE is based on signaling.

For the case that the indication information is the seventh indication information indicating whether the Logged MDT measurement result of the UE has been reported, whether the Logged MDT measurement result of the UE has been reported may be represented by specific data, for example, whether the Logged MDT measurement result of the UE has been reported is represented by using 1bit identification data.

For the case that the indication information is the eighth indication information indicating whether the UE has completed the signaling-based Logged MDT measurement, it may be represented by specific data whether the UE has completed the signaling-based Logged MDT measurement, for example, using 1-bit identification data to represent whether the UE has completed the signaling-based Logged MDT measurement.

For the case that the indication information is the remaining time of the signaling-based Logged MDT measurement corresponding to the UE, the remaining time of the signaling-based Logged MDT measurement corresponding to the UE may be represented by specific data. When the remaining time of the signaling-based Logged MDT measurement corresponding to the UE is not zero, it may be determined that the configuration type of the minimization of drive test Logged MDT of the current UE is signaling-based.

The indication information may be a combination of a plurality of kinds of information, for example, the indication information may be a combination of the third indication information, the fifth indication information, and the sixth indication information.

Optionally, the indication information is carried in any one or more of the following messages and sent:

switching preparation of inter-node messages;

interface information of the switching request;

interface messages retrieved by the UE context.

For the case where the message prepares an inter-node message for handover, the handover preparation inter-node message is inter-node information for the second network device to send handover preparation to the first network device. The Handover Preparation internode message includes Handover Preparation Information (Handover Preparation Information), in order to solve the problem of notifying the first network device of the Logged MDT type of the current UE, indication Information may be added to the Handover Preparation Information in the Handover Preparation internode message.

The Handover Preparation Information structure in the Handover Preparation internode message is as follows:

the related indication is added in the message between the Handover Preparation nodes, and the indication Information can be added in the root directory of the Handover Preparation Information message or in the structures such AS AS-Config or AS-Context IE and the like.

For the case that the message is an interface message of a handover request, the interface message of the handover request is sent by the second network device to the first network device to request information related to resources prepared for handover. As shown in table 1, the interface message of the Handover request includes Handover Preparation Information, and in order to solve the problem of notifying the Logged MDT type of the current UE to the first network device, indication Information may be added to the interface message of the Handover request.

Table 1. Part of the contents of the interface message of the handover request in the xn interface application flow protocol

For the interface message retrieved for the UE context, the interface message retrieved for the UE context is the UE context information of the current UE replied to the first network device by the second network device when the first network device requests the second network device to acquire the UE context. As shown in table 2, the interface message retrieved by the UE context includes Handover Preparation Information, and in order to solve the problem of notifying the first network device of the Logged MDT type of the current UE, indication Information may be added to the interface message retrieved by the UE context.

Table 2. Part of the content of the interface message retrieved by the UE context in the xn interface application flow protocol

It is to be appreciated that the indication information can be carried in the UE context of any one or more of the messages provided by the embodiments of the present application.

According to the method for processing the drive test information provided by the embodiment of the application, when the first network device receives any one or more messages, the first network device can know whether the current UE stores the Logged MDT configuration information and/or the measurement result based on the signaling through the indication information carried by any one or more messages, and accordingly, whether the UE is allowed to be configured with the Logged MDT based on the management is judged, and possible rule violation situations that the MDT configuration type based on the management covers the MDT configuration type based on the signaling are avoided.

Optionally, after receiving the indication information sent by the second network device, the method further includes:

storing the indication information in a UE context of the UE.

Specifically, after receiving the indication information sent by the second network device, the first network device may store the received indication information in the UE context of the UE. In the case where the communication connection change occurs again, the first network device is a network device connected to the UE before the communication connection change occurs, and the indication information is stored in the UE context of the UE, so that in this case, the first network device may select a network device connected as a target device to the network device connected to the UE after the communication connection change occurs or the UE after the communication connection change occurs, and transmit the indication information.

Optionally, the determining, according to the indication information, a configuration type of the Logged MDT of the UE is based on signaling, and includes:

and under the condition that connection with the UE is established and the UE context of the UE is stored, determining the configuration type of the Logged MDT of the UE based on the indication information carried in the UE context.

Establishing connection means that the UE accesses the first network device and establishes communication connection with the first network device, for example, the UE is successfully handed over to the first network device when the UE moves to trigger network device handover. After the connection is established, the UE may receive the MDT configuration in a connected state.

The indication information may be carried by the UE context. The first network equipment successfully receives and stores the UE context of the current UE sent by the second network equipment, wherein the UE context carries the indication information. The first network device may determine the configuration type of the Logged MDT of the UE through indication information carried in a UE context.

And under the condition that the connection is determined to be established, determining whether to configure the managed Logged MDT to the UE or not based on the indication information carried in the context of the UE, so that the condition that the UE is taken as a candidate UE under the condition that the connection state is uncertain, and the MDT configuration is carried out on the UE, but the UE is not successfully connected, so that the UE cannot apply the MDT configuration newly issued by the first network equipment is avoided.

In an embodiment, after receiving the Logged MDT configuration, the UE does not enter an IDLE/INACTIVE state for measurement, but performs handover and successfully switches to the first network device, where the first network device stores UE context information of the current UE and indication information carried by the UE context information and used for indicating whether the UE is configured with the Logged MDT based on signaling. And if the current UE stores signaling-based Logged MDT configuration information and the first network equipment organizes management-based Logged MDT, determining not to configure the management-based Logged MDT to the UE, namely the UE is not used as candidate UE of the first network equipment based on the management Logged MDT.

In an embodiment, when the UE does not enter an IDLE/INACTIVE state for measurement after receiving the Logged MDT configuration, handover occurs and fails, or the UE fails to perform radio link failure, the UE may select a suitable cell to initiate re-establishment. After the UE reestablishes to the first network device: if the first network device stores UE context information of the UE, if the UE context of the UE is received before, the indication information indicating whether the UE stores signaling-based Logged MDT configuration in the UE context may be directly applied to determine whether the UE may be configured with management-based Logged MDT.

Optionally, the method further comprises:

For the case that the first network device establishes a connection with the UE and does not store the UE context of the UE, there are two cases:

for example, if the UE receives the MDT configuration at the network device a, and if the network device a does not send a handover preparation to the network device B (possibly, does not send any handover preparation at all, or sends a handover preparation to a network device other than the network device B), a Radio Link Failure (RLF) or a handover Failure occurs, if the network device B is re-accessed, the network device B is used as the first network device, and the network device B does not store the UE context of the UE.

For another example, if the UE receives the MDT configuration at network device a, enters the unconnected state to start Logged MDT measurement, then establishes/recovers the connection at network device B, and RLF or handover failure occurs when network device B does not send handover preparation to network device C (possibly, no handover preparation is sent at all, or handover preparation is sent to a network device other than network device C), then if network device C is re-accessed, network device C serves as the first network device, and the network device C does not store the UE context of the UE.

In a case where it is determined that a connection is established with the UE and the UE context of the UE is not stored, the first network device may send a request message to the second network device requesting the second network device to send the UE context. Then, the first network device may receive a UE context of the UE sent by the second network device, where the UE context stores the indication information.

In an embodiment, after receiving the Logged MDT configuration, the UE may select a suitable cell to initiate the reestablishment if the UE does not enter an IDLE/INACTIVE state for measurement, but performs handover and fails to perform handover, or otherwise performs a radio link failure. After the UE is re-established to the first network device, if the first network device does not store the context information of the UE, a request message may be sent to a second network device of the UE to request the context information of the UE, that is, the indication information carried in the UE context information is retrieved through a context information retrieving process. After retrieving the context information of the UE, the first network device applies indication information of whether the UE holds signaling-based Logged MDT configuration, and determines whether management-based Logged MDT can be configured for the UE.

Optionally, the determining to establish a connection with the UE includes:

For the successful handover of the UE to the first network device, the handover is performed by the UE and the UE is successfully handed over to the first network device.

If the UE fails to switch to the second network device and is reestablished to the first network device, that is, if the UE fails to switch, the UE selects a suitable cell to initiate reestablishment and successfully reestablishes to the first network device.

If the UE fails to establish the radio link in the second network device and reestablishes the radio link to the first network device, that is, if the UE fails to establish the radio link, the UE may select a suitable cell to initiate reestablishment and successfully reestablish the radio link to the first network device.

Fig. 2 is a second schematic flowchart of a method for processing drive test information according to an embodiment of the present application, and as shown in fig. 2, the method is applied to a second network device, and includes:

step 200, determining a first network device;

during the Logged MDT measurement performed by the UE, the network device establishing a communication connection with the UE may change. The second network device may determine the first network device through messages such as a signaling issued by the control plane, a cell measurement report sent by the user equipment, and a handover request sent by the first network device.

Step 210, sending indication information to the first network device, where the indication information is used to characterize a configuration type of a Logged MDT of a UE, so that the first network device determines, according to the indication information, that the configuration type of the Logged MDT of the UE is signaling-based.

The second network device establishes a connection with the UE before the network device changes, the second network device may send MDT configuration to the UE and receive MDT measurement results reported by the UE, and store the MDT configuration and the measurement results, and the second network device may also learn and store the MDT configuration information of the UE through the method for processing drive test information in fig. 1.

After the network device changes, the second network device sends the indication information to the first network device, and the second network device may actively send the indication information to the first network device, or may send the indication information according to a request of the first network device. The indication information is used for representing the configuration type of the Logged MDT of the UE, so that the first network equipment determines that the configuration type of the Logged MDT of the UE is based on signaling according to the indication information. It is understood that the UE herein is the same UE as the UE having the communication connection change, and the UE may also be referred to as a current UE.

According to the method for processing the drive test information, the second network device sends the indication information to the first network device, and the first network device can acquire the configuration type of the minimum drive test Logged MDT of the user equipment UE based on the indication information, and further determine whether to configure the management-based Logged MDT to the UE. Thereby avoiding a possible rule violation situation that the management-based MDT configuration covers the signaling-based MDT configuration; or the situation that the UE stores the MDT configuration information and/or the measurement result based on the signaling and cannot apply the MDT configuration based on the management newly issued by the network side is avoided.

Optionally, the indication information includes any one or more of:

and the residual time of the Logged MDT measurement corresponding to the UE based on the signaling.

Any selection of the indication information can refer to the description in fig. 1, and is not described in detail here.

Optionally, the indication information is stored in a UE context of the UE.

switching preparation of inter-node messages;

interface information of the switching request;

interface messages retrieved by the UE context.

Any selection of messages can be referred to the description in fig. 1, and will not be described in detail here.

Optionally, the sending the indication information to the first network device includes:

And the UE receives the MDT configuration in the connected state, performs MDT measurement in the IDLE/INACTIVE state, stores the measurement data, and reports the measurement result when the UE enters the connected state again.

The condition that the MDT configuration is sent to the UE and the MDT measurement result reported by the UE is not received refers to a condition that the current UE directly changes a cell in a connected state after receiving the Logged MDT configuration in the connected state, and the current UE does not enter an IDLE/INACTIVE state to perform Logged MDT measurement, so that the current UE only has the Logged MDT configuration and does not have the Logged MDT measurement result. In this case, the indication information is sent to the first network device, and the current UE does not have a Logged MDT measurement result, so that the indication information does not include seventh indication information indicating whether the Logged MDT measurement result of the UE has been reported.

The condition that all or part of the MDT measurement results reported by the UE are received refers to the condition that the UE enters the connected state after entering the IDLE/INACTIVE state and logging MDT measurement is carried out. At this time, the current UE may complete all Logged MDT measurements and store all Logged MDT measurement results, or may complete part of Logged MDT measurements and store part of Logged MDT measurement results. In this case, the indication information is sent to the first network device, and since the current UE stores the Logged MDT measurement result, the indication information may include seventh indication information indicating whether the Logged MDT measurement result of the UE has been reported.

Fig. 3 is a third schematic flow chart of a method for processing drive test information according to an embodiment of the present invention, and as shown in fig. 3, the method is applied to a case where, after receiving a Logged MDT configuration, a UE does not enter an IDLE/INACTIVE state for measurement, but performs handover and successfully switches to a first network device, and includes the following steps:

step 300, the second network device sends indication information to the first network device, wherein the indication information is used for representing the configuration type of the Logged MDT of the UE;

in step 310, the first network device determines whether to configure a Logged MDT based on management to the UE according to the indication information.

Specifically, the second network device sends an inter-node message or a handover request message for handover preparation to the first network device. The method comprises the steps that a first network device receives an inter-node message or a switching request message prepared by switching, the first network device stores a UE context in the inter-node message or the switching request interface message prepared by switching, and the UE context carries indication information used for representing the configuration type of the Logged MDT of the UE.

And if the first network equipment knows that the current UE does not store the Logged MDT configuration information based on the signaling according to the indication information, the first network equipment determines that the Logged MDT based on management can be configured for the UE. Optionally, the first network device may determine, according to the indication information, to configure a user equipment list based on the managed Logged MDT, where the user equipment list may include the UE, that is, the first network device may use the UE as a candidate UE for the first network device based on the managed Logged MDT.

And if the first network equipment learns that the current UE really stores the Logged MDT configuration information based on the signaling according to the indication information and the first network equipment organizes the Logged MDT based on the management, the first network equipment determines not to configure the Logged MDT based on the management to the UE. Optionally, the first network device may determine, according to the indication information, to configure a UE list based on the managed Logged MDT, where the UE is not included in the UE list, that is, the UE is excluded from the candidate UE list, and the UE is not used as a candidate UE for the first network device based on the managed Logged MDT.

Fig. 4 is a fourth schematic flow chart of a method for processing drive test information according to an embodiment of the present application, and as shown in fig. 4, the method is applied to a case where, after receiving a Logged MDT configuration, a UE does not enter an IDLE/INACTIVE state for measurement, but a handover failure or a radio link failure occurs, and includes the following steps:

in step 400, the second network device sends indication information to the first network device, where the indication information is used to characterize a configuration type of the Logged MDT of the UE.

Specifically, the second network device sends a handover-prepared inter-node message or handover request message to the first network device, where the handover-prepared inter-node message or handover request message carries indication information.

Step 410, in case that it is determined that connection with the UE is established and the UE context of the UE is not stored, sending a request message to the second network device, requesting the second network device to send the UE context; wherein, the UE context carries the indication information.

Specifically, under the condition that the first network device does not store the UE context, for example, under the condition that the first network device does not receive an inter-node message or a handover request message of handover preparation sent by the second network device; or the first network equipment does not successfully store the UE context information in the node-node message or the switching request message of the switching preparation; the first network device may send a request message to a second network device of the UE to request context information of the UE, that is, retrieve indication information carried in the UE context information through a context information retrieval process.

In step 420, the second network device sends, to the first network device, indication information based on the request message, where the indication information is used to characterize a configuration type of the Logged MDT of the UE.

Specifically, the second network device sends the UE context of the UE to the first network device according to the request message sent by the first network device; the UE context carries indication information, and the indication information is used for representing the configuration type of the minimization of drive test (Logged MDT) of the UE.

In step 430, the first network device determines whether to configure a management-based Logged MDT to the UE according to the indication information.

The method comprises the steps that under the condition that first network equipment determines that UE fails to switch in second network equipment and is rebuilt to the first network equipment or determines that UE fails in a wireless link in the second network equipment and is rebuilt to the first network equipment, whether the UE stores information configured by Logged MDT based on signaling or not is determined according to indication information carried by stored UE context information, and whether the UE can be configured with Logged MDT based on management or not is determined.

Optionally, the UE context information stored by the first network device may be the UE context information in the handover preparation inter-node message or the handover request message sent by the second network device and received in step 400, or may be the UE context information retrieved in step 410. It can be understood that, in the case that the first network device stores the UE context of the UE through step 400, whether the UE stores the information of the Logged MDT configuration based on the signaling in the context may be directly applied, and a request message does not need to be sent to the second network device.

And if the first network equipment knows that the current UE does not store the signaling-based Logged MDT configuration information according to the indication information, the first network equipment determines that the management-based Logged MDT can be configured for the UE. Optionally, the first network device may determine, according to the indication information, to configure a user equipment list based on the managed Logged MDT, where the user equipment list may include the UE, that is, the first network device may use the UE as a candidate UE for the first network device based on the managed Logged MDT.

And if the first network equipment knows that the current UE really stores the Logged MDT configuration information based on the signaling according to the indication information and the first network equipment organizes the Logged MDT based on the management, the first network equipment determines not to configure the Logged MDT based on the management to the UE. Optionally, the first network device may determine, according to the indication information, to configure a user equipment list based on the managed Logged MDT, where the user equipment list does not include the UE, that is, the UE is excluded from the candidate UE list, and the UE is not used as a candidate UE for the first network device based on the managed Logged MDT.

Fig. 5 is a fifth schematic flow chart of a method for processing drive test information according to an embodiment of the present disclosure, and as shown in fig. 5, the method is applied to a case where, after receiving a Logged MDT configuration, a UE does not enter an IDLE/INACTIVE state for measurement, but a handover failure or a radio link failure occurs, and includes the following steps:

step 500, a first network device sends a request message to a second network device, requesting the second network device to send a UE context of a UE; the UE context carries indication information, and the indication information is used for representing the configuration type of the minimization of drive test (Logged MDT) of the UE.

Specifically, the second network device does not send the handover-prepared inter-node message or the handover request message to the first network device, and therefore the first network device cannot receive and store the UE context in the handover-prepared inter-node message or the handover request message. In this embodiment, the first network device directly sends a request message to the second network device of the UE to request the UE context information, that is, the indication information carried in the UE context information is retrieved through the context information retrieving process.

In step 510, the second network device sends indication information to the first network device, where the indication information is used to characterize a configuration type of the Logged MDT of the UE.

In step 520, the first network device determines whether to configure a management-based Logged MDT to the UE according to the indication information.

Under the condition that the UE fails to switch and is rebuilt to the first network equipment, or under the condition that the UE is determined to have wireless link failure and is rebuilt to the first network equipment, the first network equipment determines whether the UE stores information configured by the Logged MDT based on the signaling or not according to the indication information carried by the retrieved UE context information, and determines whether the management-based Logged MDT can be configured for the UE or not.

And if the first network equipment knows that the current UE does not store the signaling-based Logged MDT configuration information according to the indication information, the first network equipment determines that the management-based Logged MDT can be configured for the UE. Optionally, the first network device may determine, according to the indication information, to configure a user equipment list based on the managed Logged MDT, where the user equipment list may include the current UE, that is, the first network device may use the UE as a candidate UE for the first network device based on the managed Logged MDT.

And if the first network equipment knows that the current UE really stores the Logged MDT configuration information based on the signaling according to the indication information and the first network equipment organizes the Logged MDT based on the management, the first network equipment determines not to configure the Logged MDT based on the management to the UE. Optionally, the first network device may determine, according to the indication information, to configure a user equipment list based on the managed Logged MDT, where the user equipment list does not include the current UE, that is, the UE is excluded from the candidate UE list, and the UE is not used as a candidate UE for the first network device based on the managed Logged MDT.

Indication information fig. 6 is a sixth schematic flow chart of a method for processing drive test information provided in an embodiment of the present application, and as shown in fig. 6, the method is applied to a case where a handover failure or a radio link failure occurs after a UE completes all or part of Logged MDT measurements and accesses a network, and includes the following steps:

step 600, the second network device sends indication information to the first network device, where the indication information is used to characterize a configuration type of a minimization of drive test, logged MDT, of the user equipment UE.

Specifically, after receiving the Logged MDT configuration, the UE enters an IDLE/INACTIVE state to perform measurement. And when the UE subsequently enters a connected state, carrying indication information of whether the UE is configured with the Logged MDT based on the signaling in a completion message of RRC establishment or recovery. At this time, the network side to which the UE accesses may determine whether to send a Logged configuration based on management to the UE. However, if the UE accesses the network, the Logged MDT measurement result is not reported yet and a handover or radio link failure occurs, the first network device that is handed over or the first network device that is reestablished after the radio link failure cannot know whether the UE stores the measurement configuration or the measurement result of the Logged MDT based on the signaling.

In this embodiment, indication information is added to an inter-node message prepared for handover and/or an interface message of a handover request, where the indication information is used to characterize a configuration type of a minimization drive test Logged MDT of a UE, so that a first network device learns the configuration type of the minimization drive test Logged MDT of the UE.

Since the embodiment is applied to the case when the UE completes all or part of the Logged MDT measurement, in this case, the current UE stores the Logged MDT measurement result, the indication information may include whether the current UE stores the Logged MDT measurement configuration based on the signaling, and/or whether the current UE stores the Logged MDT measurement result based on the signaling, and/or whether the Logged MDT measurement based on the signaling is completed, and the like, that is, the indication information may include one or more of the following:

whether the UE is configured with first indication information of the Logged MDT and whether the MDT configuration of the UE is second indication information based on signaling;

whether the UE stores fourth indication information of the Logged MDT measurement result and whether the MDT measurement result of the UE is fifth indication information based on signaling;

whether the measurement result of the Logged MDT stored by the UE is sixth indication information based on the signaling;

seventh indication information indicating whether the Logged MDT measurement result of the UE is reported or not;

eighth indication information whether the UE has completed the signaling-based Logged MDT measurement;

the remaining time of the corresponding signaling-based Logged MDT measurement of the UE.

Step 610, under the condition that connection with the UE is established and the UE context of the UE is not stored, sending a request message to the second network equipment to request the second network equipment to send the UE context; wherein, the UE context carries the indication information.

Specifically, under the condition that the first network device does not store the UE context, for example, under the condition that the first network device does not receive an inter-node message or a handover request message of handover preparation sent by the second network device; or the first network equipment does not successfully store the UE context information in the node-node message or the switching request message of the switching preparation; the first network device may send a request message to the second network device of the UE, requesting UE context information of the UE, that is, retrieving the indication information carried in the UE context information through a context information retrieving process.

Specifically, since the present embodiment is applied to a case when the UE completes all or part of the Logged MDT measurement, in this case, because the Logged MDT measurement result is stored in the current UE, the indication information carried in the retrieved UE context information may include seventh indication information indicating whether the Logged MDT measurement result of the UE has been reported. The Logged MDT measurement result further includes all configuration information, and the configuration information includes a configuration type, that is, the measurement result may indicate whether the type is signaling-based.

Step 620, the second network device sends indication information to the first network device based on the request message, where the indication information is used to characterize a configuration type of the minimization of drive test, logged MDT, of the user equipment UE.

In step 630, the first network device determines whether to configure a management-based Logged MDT to the UE according to the indication information.

The method comprises the steps that a first network device determines whether UE stores signaling-based Logged MDT configuration or not through indication information carried by stored UE context information under the condition that the UE fails in switching of a second network device and is rebuilt to the first network device or the condition that the UE fails in wireless link of the second network device and is rebuilt to the first network device, and determines whether the UE can be configured with management-based Logged MDT or not.

Optionally, the UE context information stored by the first network device may be UE context information in the handover preparation inter-node message or the handover request message sent by the second network device and received in step 400, or may be UE context information retrieved in step 610. It can be understood that, if the first network device stores the UE context of the UE through step 600, it may directly apply whether the UE stores the information of the Logged MDT configuration based on the signaling in the UE context, and does not need to send the request message to the second network device.

And if the first network equipment knows that the current UE really stores the Logged MDT configuration information based on the signaling according to the indication information and the first network equipment organizes the Logged MDT based on the management, the first network equipment determines not to configure the Logged MDT based on the management to the UE. Optionally, the first network device may determine, according to the indication information, to configure a user equipment list based on the managed Logged MDT, where the user equipment list does not include the current UE, that is, the UE is excluded from the candidate UE list, and the UE is not used as a candidate UE based on the managed Logged MDT for the first network device.

In the embodiment of the application, the first network equipment for switching or reestablishment obtains the instruction information of the Logged MDT of the UE, which is about based on the signaling, and then determines whether the Logged MDT based on management can be configured for the UE or not based on the instruction information, so that the possible condition that the configuration based on the managed MDT covers the violation principle condition based on the configuration of the signaling MDT is avoided; or the situation that the UE cannot apply the management-based MDT configuration newly issued by the network device because the signaling-based MDT configuration information and/or the measurement result are stored, or the measurement result is covered is avoided.

Fig. 7 is a seventh schematic flow diagram of a method for processing drive test information according to an embodiment of the present application, and as shown in fig. 7, the method is applied to a case where a handover failure or a radio link failure occurs after a UE completes all or part of Logged MDT measurements and accesses a network, and includes the following steps:

step 700, a first network device sends a request message to a second network device, requesting the second network device to send a UE context of a UE to the first network device; the UE context carries indication information, and the indication information is used for representing the configuration type of the minimization of drive test (Logged MDT) of the UE.

Specifically, since the indication information is added to the interface message retrieved by the UE context sent by the second network device, the first network device may learn the configuration type of the Logged MDT of the UE based on the UE context. Since the embodiment is applied to the case when the UE completes all or part of the Logged MDT measurement, in this case, because the current UE stores the Logged MDT measurement result, the indication information may include whether the current UE stores the Logged MDT measurement configuration based on the signaling, and/or whether the current UE stores the Logged MDT measurement result based on the signaling, and/or whether the Logged MDT measurement based on the signaling is completed, and the like, that is, the indication information may include one or more of the following:

Specifically, the second network device does not send the handover-prepared inter-node message or the handover request message to the first network device, and therefore the first network device cannot receive and store the UE context in the handover-prepared inter-node message or the handover request message. In this embodiment, the first network device may directly send a request message to the second network device of the UE to request the context information of the UE, that is, retrieve the indication information carried in the context information of the UE through the context information retrieval process.

Step 710, the second network device sends indication information to the first network device, where the indication information is used to characterize a configuration type of the minimization of drive test, logged MDT, of the user equipment UE.

Specifically, the second network device sends the UE context of the UE to the first network device according to a request message sent by the first network device; the UE context carries indication information, and the indication information is used for representing the configuration type of the minimization of drive test (Logged MDT) of the UE.

In step 720, the first network device determines whether to configure a management-based Logged MDT to the UE according to the indication information.

The first network equipment determines whether the UE stores signaling-based Logged MDT configuration information or not according to the retrieved indication information carried by the UE context information under the condition that the UE fails in switching of the second network equipment and is rebuilt to the first network equipment or under the condition that the UE fails in wireless link of the second network equipment and is rebuilt to the first network equipment, and determines whether the UE can be configured with management-based Logged MDT or not.

And if the first network equipment knows that the current UE does not store the signaling-based Logged MDT configuration information according to the indication information, the first network equipment determines that the UE can be configured with the management-based Logged MDT. Optionally, the first network device may determine, according to the indication information, to configure a user equipment list based on the managed Logged MDT, where the user equipment list may include the UE, that is, the first network device may use the UE as a candidate UE for the first network device based on the managed Logged MDT.

And if the first network equipment knows that the current UE really stores the Logged MDT configuration information based on the signaling according to the indication information and the first network equipment organizes the Logged MDT based on the management, the first network equipment determines not to configure the Logged MDT based on the management to the UE. Optionally, the first network device may determine, according to the indication information, to configure a UE list based on the managed Logged MDT, where the UE is not included in the UE list, that is, the UE is excluded from the candidate UE list, and the UE is not used as a candidate UE for the first network device based on the managed Logged MDT.

According to the method for processing the drive test information, after the first network equipment retrieves the UE context carrying the indication information from the second network equipment, whether the UE context is allowed to be sent to the current UE is judged according to the indication information, and the Logged MDT based on management is configured, so that the possible violation principle condition that the MDT configuration based on management covers the MDT configuration based on signaling is effectively avoided; or the situation that the UE stores the MDT configuration information and/or the measurement result based on the signaling and cannot apply the MDT configuration based on the management newly issued by the network side is avoided.
