Before the technical scheme of the application is described, some technical knowledge related to the application is described.

Non-terrestrial network (Non-TERRESTRIAL NETWORK, NTN) technology

Currently, the related standards organization is researching NTN technology, which generally provides communication services to terrestrial users by adopting a satellite communication mode. Satellite communications have many unique advantages over terrestrial cellular communication networks. First, satellite communications are not limited by the user region, for example, general land communications cannot cover areas where communication devices cannot be installed, such as oceans, mountains, deserts, etc., or communication coverage is not performed due to rarity of population, while for satellite communications, since one satellite can cover a larger ground, and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communications. And secondly, satellite communication has great social value. Satellite communication can be covered in remote mountain areas, poor and backward countries or regions with lower cost, so that people in the regions enjoy advanced voice communication and mobile internet technology, and the digital gap between developed regions is reduced, and the development of the regions is promoted. Again, the satellite communication distance is far, and the cost of communication is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into low earth Orbit (LowEarth Orbit, LEO) satellites, medium earth Orbit (MediumEarth Orbit, MEO) satellites, geosynchronous Orbit (Geostationary Earth Orbit, GEO) satellites, high elliptical Orbit (HIGH ELLIPTICAL Orbit, HEO) satellites, and the like, according to the Orbit heights. LEO and GEO are the main studies at the present stage.

1、LEO

The low orbit satellite has a height ranging from 500km to 1500km and a corresponding orbit period of about 1.5 hours to 2 hours. The signal propagation delay for single hop communications between users is typically less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the user terminal equipment is not high.

2、GEO

Geosynchronous orbit satellites have an orbit altitude of 35786km and a period of 24 hours around the earth. The signal propagation delay for single hop communications between users is typically 250ms.

In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form tens or hundreds of beams to cover the ground; a satellite beam may cover a ground area of several tens to hundreds of kilometers in diameter.

In order to adapt to the characteristics of satellite communication scenes, on the basis of a traditional cell switching mechanism, the satellite communication introduces a timing switching and distance switching mechanism:

And (3) timing switching: the network device configures a handover time window and a handover measurement event in the handover message, and the terminal device can initiate a handover procedure only when the measurement result of the candidate handover cell (candidate target cell) satisfies the handover measurement event within the handover time window.

Distance switching: the network equipment configures a switching distance event and a switching measurement event in the switching message, and the terminal equipment can initiate a switching process only when the switching distance event is satisfied and the measurement result of the candidate switching cell is satisfied.

The embodiment of the application can be applied to an NTN system as shown in fig. 1 and 2 and also can be applied to a TN system as shown in fig. 3.

Referring to fig. 1, a schematic diagram of an NTN system is shown, where the communication satellite is a transparent forwarding (TRANSPARENT PAYLOAD) satellite. As shown in fig. 1, the NTN system includes: terminal equipment 10, satellites 20, NTN gateway 30, access network equipment 40 and core network equipment 50.

Communication between the terminal device 10 and the access network device 40 may be performed via an air interface, such as the Uu interface. In the architecture shown in fig. 1, the access network device 40 may be deployed on the ground, and uplink and downlink communications between the terminal device 10 and the access network device 40 may be relayed through the satellite 20 and the NTN gateway 30 (typically located on the ground). Taking uplink transmission as an example, the terminal device 10 sends an uplink signal to the satellite 20, the satellite 20 forwards the uplink signal to the NTN gateway 30, the NTN gateway 30 forwards the uplink signal to the access network device 40, and the access network device 40 subsequently sends the uplink signal to the core network device 50. Taking downlink transmission as an example, the downlink signal from the core network device 50 is sent to the access network device 40, the access network device 40 sends the downlink signal to the NTN gateway 30, the NTN gateway 30 forwards the downlink signal to the satellite 20, and the satellite 20 forwards the downlink signal to the terminal device 10.

Referring to fig. 2, a schematic diagram of another NTN system is shown, in which the communication satellite is a regenerative repeating (REGENERATIVE PAYLOAD) satellite. As shown in fig. 2, the NTN system includes: a terminal device 10, a satellite 20, an NTN gateway 30 and a core network device 50.

In the architecture shown in fig. 2, the functionality of the access network device 40 is integrated on the satellite 20, i.e. the satellite 20 is provided with the functionality of the access network device 40. Communication between the terminal device 10 and the satellite 20 may be via an air interface, such as the Uu interface. Communication between the satellite 20 and the NTN gateway 30 (typically located on the ground) may be via a satellite radio interface (SATELLITE RADIO INTERFACE, SRI).

In the architecture shown in fig. 2, taking uplink transmission as an example, the terminal device 10 transmits an uplink signal to the satellite 20, the satellite 20 forwards the uplink signal to the NTN gateway 30, and the NTN gateway 30 transmits the uplink signal to the core network device 50. Taking downlink transmission as an example, a downlink signal from the core network device 50 is sent to the NTN gateway 30, and the NTN gateway 30 forwards the downlink signal to the satellite 20, and then the satellite 20 forwards the downlink signal to the terminal device 10.

Referring to fig. 3, a schematic diagram of a TN system is shown. As shown in fig. 3, the TN system includes: terminal device 10, access network device 40 and core network device 50.

Communication between the terminal device 10 and the access network device 40 may be performed via an air interface, such as the Uu interface. Taking uplink transmission as an example, the terminal device 10 sends an uplink signal to the access network device 40, and the access network device 40 subsequently sends the uplink signal to the core network device 50. Taking downlink transmission as an example, the downlink signal from the core network device 50 is sent to the access network device 40, and the access network device 40 sends the downlink signal to the terminal device 10.

In the network architecture shown in fig. 1,2 and 3 described above, the access network device 40 is a device for providing wireless communication services to the terminal device 10. A connection may be established between the access network device 40 and the terminal device 10 so that communication, including interaction of signaling and data, may take place over the connection. The number of access network devices 40 may be plural, and communication between two adjacent access network devices 40 may be performed by wired or wireless means. The terminal device 10 may switch between different access network devices 40, i.e. establish a connection with different access network devices 40.

Taking a cellular communication network as an example, the access network device 40 in the cellular communication network may be a base station. A base station is a device deployed in an access network to provide wireless communication functionality for a terminal device 10. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. The names of base station enabled devices may vary in systems employing different radio access technologies, for example in 5G NR systems, referred to as gNodeB or gNB. As communication technology evolves, the name "base station" may change. For convenience of description, in the embodiment of the present application, the above-mentioned devices for providing the terminal device 10 with a wireless communication function are collectively referred to as a base station or an access network device.

In addition, the terminal device 10 according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), mobile Station (MS), terminal devices (TERMINAL DEVICE), and so on. For convenience of description, in the embodiment of the present application, the above-mentioned devices are collectively referred to as a terminal device. In the embodiment of the present application, some places use "UE" to represent "terminal equipment". In an embodiment of the present application, the "network device" may be an access network device (e.g., a base station) or a satellite.

In addition, taking a 5G NTN system as an example, a plurality of satellites 20 may be included in the NTN system. One satellite 20 may cover a range of ground areas and provide wireless communication services to the terminal devices 10 on that ground area. In addition, the satellites 20 may orbit the earth, and by deploying multiple satellites 20, communication coverage of different areas of the earth's surface may be achieved.

In addition, in embodiments of the present application, the terms "network" and "system" are generally used in combination, but those skilled in the art will understand the meaning. The technical solution described in the embodiments of the present application may be applied to a long term evolution (Long Term Evolution, LTE) system, a 5G system, a subsequent evolution system of a 5G NR system, or other communication systems, which is not limited in this aspect of the present application.

Referring to fig. 4, a flowchart of a control method for optimizing a handover procedure according to an embodiment of the application is shown. The present embodiment is exemplified by the application of the method to the communication system shown in fig. 1,2 or 3. The method may comprise the steps of:

step 210: the terminal device sends a first message to the network device, wherein the first message comprises radio link failure report information and/or cell handover success report information.

The radio link failure report information comprises data information recorded in a radio link failure scene or data recorded in a handover failure scene.

Illustratively, the radio link failure cause corresponding to the radio link failure scenario is any one of the following:

the synchronization control timer T310 times out, the random access attempt reaches a maximum number of attempts, the radio link control layer re-conveys to a maximum number of retransmissions, the beam recovery fails, the fast re-establishment control timer T312 times out, or the backhaul link fails.

At least one data item in the radio link failure report information and/or the cell handover success report information is associated with a satellite communication scenario. At least one data item in the radio link failure report information and/or the cell handover success report information is acquired from a satellite communication scenario.

The terminal equipment records related data items in the process of radio link connection and cell switching with a satellite (with the function of network equipment), generates a first message and sends the first message to the network equipment.

For example, the first message may include radio link failure report information of at least one radio link failure or at least one handover failure, and/or cell handover success report information of at least one cell handover success.

That is, the terminal device may send a first message to the network device after each radio link failure or each handover failure, where the first message includes radio link failure report information of the present radio link failure or handover failure. Or, the terminal device may send a first message to the network device after each cell handover is successful, where the first message includes cell handover success report information that the cell handover is successful.

Or, the terminal device may record radio link failure report information of each radio link failure or each handover failure, and cell handover success report information of each cell handover success. The terminal device sends a first message to the network device, wherein the first message comprises radio link failure report information of at least one radio link failure or at least one switching failure of the terminal device, and/or cell switching success report information of at least one cell switching success. The terminal device may report the last several times of radio link failure report information and/or cell handover success report information, which have not been reported, to the network device.

Step 220: the network device receives a first message sent by the terminal device.

The network device optimizes the handover procedure of the terminal device according to the radio link failure report information and/or the cell handover success report information fed back by the terminal device.

In summary, according to the technical solution provided in this embodiment, the terminal device records information in the radio link and cell switching process, sends a first message to the network device, and carries at least one of radio link failure report information and cell switching success report information in the first message, and provides an adaptive optimization feedback mechanism for a new satellite switching mechanism, so as to feed back information in the satellite switching process to the network device, solve the optimization problem of the satellite system switching process, and improve the user experience in the satellite communication switching process.

Illustratively, the radio link failure report information includes at least one of the following 14 data items:

Data item 1: the network equipment configures configuration information corresponding to at least one condition switching event of the terminal equipment;

The network device is illustratively configured with at least one candidate target cell for the terminal device, each candidate target cell being configured with at least one conditional handover event.

The conditional switch event includes any one of the following event types:

Condition A3 event: the measurement result of the target handover cell (candidate target cell) is higher than the measurement result of the current PCell (primary cell)/PSCell (primary secondary cell) of the terminal device by a first threshold;

Condition A4 event: the measurement result of the target handover cell (candidate target cell) is higher than the second threshold;

Condition A5 event: the measurement result of the current PCell/PSCell of the terminal equipment is lower than a third threshold value, and the measurement result of a target handover cell (candidate target cell) is higher than a fourth threshold value;

condition D1 event: the distance between the terminal device and the position reference point 1 is greater than a fifth threshold value and the distance between the terminal device and the position reference point 2 is less than a sixth threshold value;

condition T1 event: the terminal device local time exceeds configured time instant 1 but does not exceed configured time instant 2.

Wherein the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the sixth threshold, the location reference point 1, the location reference point 2, the time instant 1 and the time instant 2 are configured by a network equipment system broadcast message (cell system broadcast message) or a dedicated signaling.

There may be two configuration formats for time 2: first, given directly in UTC (Universal Time Coordinated, coordinated universal time) time, for example, in the form of chrono-minute-second: 2021.11.25 17:43:05; the second, given indirectly according to time 1, gives a fixed duration, time 2=time 1+a fixed duration, for example, time 2 is a time corresponding to 20 seconds after time 1, and the configuration format of time 2 is not limited in the present application.

The configuration information corresponding to the conditional switching event includes event type information and configuration information of related parameters corresponding to the event type. For example, the configuration information corresponding to the conditional switching event includes event type information and threshold configuration information corresponding to the event type; or, the configuration information corresponding to the conditional switching event comprises event type information and time configuration information corresponding to the event type.

In another implementation manner, the configuration information corresponding to the conditional switching event is reported according to the granularity of the candidate target cell, namely: simultaneously reporting a candidate target cell identifier, event type information configured for the candidate target cell and configuration information of related parameters corresponding to the event type, wherein the candidate target cell identifier is represented by a cell global identifier (Cell Global Identifier, CGI); or by frequency point + physical cell identity (PHYSICALCELLIDENTIFIER, PCI).

The event type/event type information includes: any one of a condition A3 event, a condition A4 event, a condition A5 event, a condition D1 event, and a condition T1 event.

The threshold configuration information corresponding to the event type is related to the event itself, and different event types correspond to different threshold configuration information.

For example, for a condition A3 event, the threshold configuration information includes a first threshold; for the condition A4 event, the threshold configuration information includes a second threshold; for the condition A5 event, the threshold configuration information includes a third threshold and a fourth threshold; for the condition D1 event, the threshold configuration information includes a fifth threshold and a sixth threshold.

The time configuration information corresponding to the event type is related to the event itself, and different event types correspond to different time configuration information.

For example, time 1 and time 2 are configured for the condition T1 event.

Data item 2: when the switching fails or the wireless link fails, the configuration information corresponding to the conditional switching event meeting the condition is provided;

data item 3: when the switching fails or the wireless link fails, the identification information corresponding to the conditional switching event meeting the condition is displayed;

data item 4: when the switching fails or the wireless link fails, the configuration information corresponding to the conditional switching event which does not meet the condition is configured;

Data item 5: when the switching fails or the wireless link fails, the identification information corresponding to the conditional switching event which does not meet the condition is displayed;

For data items 2 to 5 described above:

For example, for one candidate target cell, the network device may configure multiple conditional handover events for the terminal device simultaneously in a handover configuration message. For example, the condition A4 event and the condition D1 event are configured simultaneously; or, configuring the condition A4 event and the condition T1 event simultaneously; or, the condition A4 event, the condition D1 event, and the condition T1 event are configured at the same time.

When at least two conditional switching events are configured for one candidate target cell, the terminal device can execute switching after all the conditional switching events are simultaneously satisfied, and initiates a connection establishment procedure to the candidate target cell (target switching cell). Since each conditional switching event is evaluated independently, a problem of condition triggering dyssynchrony of at least two conditional switching events configured for one candidate target cell occurs, and even when a terminal device fails to switch or fails to radio link, some conditional switching events satisfy the condition, and some conditional switching events do not satisfy the condition, so that different recorded data from data item 2 to data item 5 occur.

When the terminal equipment fails to switch or the radio link fails, in the condition switching event corresponding to the candidate target cell (target switching cell), the configuration information corresponding to the condition switching event meeting the condition is provided; when the terminal equipment fails to switch or the radio link fails, in the condition switching event corresponding to the candidate target cell (target switching cell), the identification information corresponding to the condition switching event meeting the condition is displayed; when the terminal equipment fails to switch or the radio link fails, configuration information corresponding to a conditional switching event which does not meet the condition is selected from conditional switching events corresponding to candidate target cells (target switching cells); when the terminal equipment fails to switch or the radio link fails, the identification information corresponding to the conditional switching event which does not meet the condition is in the conditional switching event corresponding to the candidate target cell (target switching cell).

The identification information corresponding to the conditional switching event comprises: any one of a condition A3 event, a condition A4 event, a condition A5 event, a condition D1 event, and a condition T1 event.

Data item 6: in the case that at least two conditional switching events are configured for one candidate target cell, duration information from the first conditional switching event of the at least two conditional switching events to the last conditional switching event being satisfied;

The first condition switching event is any one of a condition A3 event, a condition A4 event, a condition A5 event, a condition D1 event and a condition T1 event. The last condition switching event is any one of a condition A3 event, a condition A4 event, a condition A5 event, a condition D1 event and a condition T1 event.

When the network equipment configures a plurality of condition switching events for one candidate target cell, in at least one condition switching event configured for one candidate target cell, the first condition switching event meeting the condition on the time sequence is the first condition switching event; the last conditional switching event satisfying the condition in time sequence is the last conditional switching event.

For example, for candidate target cell 1, the network device is configured with two conditional handover events: and if the condition A4 event firstly meets the condition, the condition A4 event is a first condition switching event, a period of time T1 passes, the condition T1 event meets the condition, the condition T1 event is a last condition switching event, and the time length information from the first condition switching event to the last condition switching event meeting the experience is T1. For another example, for candidate target cell 2, the network device coordinates three conditional handover events: if the condition D1 event firstly meets the condition, the condition D1 event is a first condition switching event, a period of time T2 passes, the condition T1 event meets the condition, the condition T1 event is a second condition switching event, then the period of time T3 passes, the condition A4 event meets the condition, the A4 event is a last condition switching event, and the time period information from the first condition switching event to the last condition switching event is t2+t3.

Data item 7: a measurement result of the cell when the first conditional handover event is satisfied;

The first condition switching event is any one of a condition A3 event, a condition A4 event, a condition A5 event, a condition D1 event and a condition T1 event.

In at least one conditional switching event configured for one candidate target cell, the first conditional switching event satisfying the condition in time sequence is the first conditional switching event.

Data item 8: a measurement result of the cell when the handover fails or the radio link fails;

Data item 9: switching type indication information;

The handover type indication information includes any one of the following information:

Indicating satellite switching;

indicating satellite condition switching;

satellite condition switching indicating participation of a condition D1 event;

Satellite condition switching in which a condition T1 event is indicated to participate;

Indicating a measurement-triggered satellite condition handoff.

The handover type indication information is used to indicate a handover type of a handover performed by the terminal device. The switching types include: satellite switching; satellite condition switching; satellite condition switching with participation of a condition D1 event; satellite condition switching with participation of a condition T1 event; at least one of a measurement-triggered satellite condition handoff.

The satellite conditional switch is a satellite switch that is performed after the conditional switch event is satisfied.

Condition D1 satellite condition handoff with event participation: the conditional D1 event is included in a conditional handover event for a satellite in which the conditional D1 event participates, i.e., a conditional handover event of a target handover cell (candidate target cell).

Since the condition D1 event may trigger a condition switch in combination with other condition switch events (e.g., condition A3 event, condition A4 event, condition A5 event), the "satellite condition switch with which the condition D1 event participates" is used to represent a satellite condition switch triggered by the condition D1 event alone or to represent a satellite condition switch triggered by the condition D1 event in combination with other condition switch events.

Conditional T1 event-participated satellite conditional handoff: the conditional T1 event is included in a conditional handover event for a satellite in which the conditional T1 event participates, i.e. a conditional handover event of a target handover cell (candidate target cell).

Since the condition T1 event may trigger a condition switch in combination with other condition switch events (e.g., condition A3 event, condition A4 event, condition A5 event), the "satellite condition switch with which the condition T1 event participates" is used to represent a satellite condition switch triggered by the condition T1 event alone, or to represent a satellite condition switch triggered by the condition T1 event in combination with other condition switch events.

Measurement-triggered satellite condition switching: the satellite condition handover involving the conditional A3 event, the conditional A4 event or the conditional A5 event, i.e. the condition handover event of the target handover cell (candidate target cell) includes at least one of the conditional A3 event, the conditional A4 event and the conditional A5 event.

The satellite condition switching triggered by the measurement result is as follows: condition A3 event or condition A4 event or condition A5 event triggered satellite condition handoff.

Data item 10: information of a cause value of handover failure or radio link failure;

the handover failure or radio link failure cause value information includes:

The terminal equipment loses network signal coverage;

or, the condition switching event evaluated by the terminal device cannot be fully satisfied.

In one implementation, if the terminal device records multiple handover failures or radio link failure data, the cause value of each handover failure or radio link failure is recorded separately.

Data item 11: the total times that the terminal equipment experiences switching failure or radio link failure within a preset duration;

Data item 12: the number of times that the terminal equipment experiences switching failure within a preset duration;

data item 13: the number of times that the terminal equipment experiences radio link failure within a preset duration;

For data items 11 to 13:

In one implementation, the terminal device records the total number of times that the terminal device experiences a handover failure or a radio link failure within a preset duration, and in this way, the terminal device does not need to distinguish between two scenes of the handover failure or the radio link failure, and only needs to record the total number of times that the handover failure or the radio link failure occurs.

In another implementation, the terminal device records the number of handover failures and/or the number of radio link failures within a preset duration. The network device can know the times of switching failure or radio link failure, so that the network device is convenient for scene division optimization.

Of course, when the terminal device records the number of handover failures and the number of radio link failures at the same time, there may be two recording modes:

Mode 1: only the number of handover failures and the number of radio link failures are recorded respectively, and the sequence information of the occurrence time of each failure is not recorded, for example: within 1 hour, 3 times of switching failure and 2 times of radio link failure occur;

Mode 2: the terminal device records the number of handover failures and the number of radio link failures, and also records the sequence information of the occurrence time of each failure, for example: within 1 hour, the first time of switching failure occurs, the second time of switching failure occurs, the third time of radio link failure occurs, the fourth time of switching failure occurs, and the fifth time of radio link failure occurs.

The preset duration is configured in any one of the following ways: configured by pre-configuration, configured by cell system broadcast messages, or configured by dedicated signaling.

Data item 14: and the position information of the terminal equipment when the handover fails or the radio link fails.

Illustratively, the handover success report information includes at least one of the following 6 data items:

data item 15: the network equipment configures configuration information corresponding to at least one condition switching event of the terminal equipment;

the data item 15 may refer to the explanation of the data item 1 described above.

Data item 16: in the case where at least two conditional switching events are configured for one candidate target cell, duration information from the first conditional switching event of at least two conditional switching times being satisfied to the last conditional switching event being satisfied to be experienced;

data item 19: the method comprises the steps that when all condition switching events are met or when terminal equipment executes condition switching, the cell measurement results are obtained;

for data items 17 to 19:

All conditional handover events refer to all conditional handover event(s) configured by the network device for one candidate target cell.

When all the condition switching events are satisfied or when the terminal device performs condition switching, it means that: at least one conditional handover event configured for one candidate target cell is all at the time when the conditions are satisfied, or at the time when the terminal device performs conditional handover to the candidate target cell (target handover cell).

In one implementation, the time of day information may be a time of day defined in UTC format.

The time scale information is: when the condition T1 event is included in all the condition switching events, the conditions of the other condition switching events satisfy the proportion of the time in the time window (time 1 to time 2) of the condition T1 event. The ratio may be the actual calculation result or the value of the interval corresponding to the actual calculation result.

For example, the condition switching event includes a condition T1 event (the event satisfying condition is that the current time is between time T1 and time T2) and a condition A4 event, if the condition A4 event is satisfied at time T3 between time T1 and time T2, time T3 is referred to as when the all condition switching event is satisfied or when the terminal device performs the condition switching, and the time ratio information is equal to the calculated percentage of (T3-T1)/(T2-T1).

Or predefining several values such as {0.2,0.4,0.6,0.8,1}, if the calculation result of (T3-T1)/(T2-T1) is smaller than 0.2, reporting the number of 0.2 by the terminal equipment, if the calculation result of (T3-T1)/(T2-T1) is smaller than 0.4 but larger than or equal to 0.2, reporting the number of 0.4 by the terminal equipment, and so on, the method can save the reporting bit number.

Data item 20: and the position information of the terminal equipment when the switching is successful.

For the data items mentioned for the cell measurement result among the above 20 data items:

The measurement results of the cell comprise measurement results of the serving cell and/or measurement results of at least one neighbor cell. The measurement results include at least one of RSRP (REFERENCE SIGNAL RECEIVED Power ), RSRQ (REFERENCE SIGNAL RECEIVED Quality, reference signal received Quality), SINR (Signal to Interference plus Noise Ratio, signal-to-interference-and-noise ratio) type measurement results.

Referring to fig. 5, a flowchart of a control method for optimizing a handover procedure according to an embodiment of the application is shown. The present embodiment is exemplified by the application of the method to the communication system shown in fig. 1,2 or 3. The method may comprise the steps of:

Step 201: the terminal device sends capability indication information to the network device.

The network equipment receives the capability indication information sent by the terminal equipment.

The capability indication information is used for indicating: the terminal device supports collecting or recording at least one item of radio link failure reporting information and/or cell handover success reporting information and/or the terminal device does not support collecting or recording at least one item of radio link failure reporting information and/or cell handover success reporting information.

Illustratively, the capability indication information is mapped to the data item as a one-to-one, one-to-many, or one-to-all data item. That is, one capability indication information indicates whether the terminal device supports collection or recording of one data item, and for a plurality of data items, the terminal device may transmit a plurality of capability indication information to indicate. Or, if one capability indication information indicates that the terminal device supports collecting or recording multiple data items, the terminal device may send one capability indication information for indicating for one group of data items, and send multiple capability indication information for multiple groups of data items respectively for indicating. Or, a capability indication information indicates whether the terminal device supports collecting or recording all data items.

In one implementation manner, all data items recorded in the first message share one capability indication information, and as long as the terminal equipment supports the capability, the terminal equipment can record any data item contained in the first message; in another implementation manner, part or all of the data items recorded in the first message correspond to independent capability indication information respectively, and the terminal device can record the corresponding item data only on the premise that the capability indication information of the corresponding data item indicates permission.

Some data items are allowed to be unassociated with any capability indication information, at which point these data items may be recorded by default by the terminal device.

Step 202: the network device sends a configuration message to the terminal device, the configuration message including data collection indication information.

The terminal device receives the configuration message. The configuration message comprises data collection indication information, and the terminal equipment records corresponding data items in the radio link failure report information and/or the cell handover success report information under the condition that the data collection indication information indicates that collection is allowed; or under the condition that the data collection indication information indicates that the collection is not allowed, the terminal equipment does not record the data items contained in the radio link failure report information and/or the cell handover success report information.

Illustratively, the data collection indication information is determined based on the capability indication information.

Illustratively, the mapping relationship of the data collection indication information and the data items is one-to-one, one-to-many or one-to-all data items. That is, one data collection instruction information indicates whether the terminal device records one item of data, and the network device may transmit a plurality of data collection instruction information for a plurality of items of data to instruct. Or, if one data collection indication information indicates that the terminal device records multiple data items, the network device may send one data collection indication information for indicating one group of data items, and send multiple data collection indication information for indicating multiple groups of data items respectively. Or, one data collection instruction information instructs the terminal device whether to record all the data items.

Illustratively, the data collection indication information is used to indicate the data items that need to be included in the first message. In one implementation, all data items recorded in the first message share one data collection indication information; in another implementation, part or all of the data items recorded in the first message have independent data collection indication information, respectively, for controlling the collection or non-collection of the individual data items.

Step 203: the terminal device sends a second message to the network device, wherein the second message comprises radio link failure report advisable indication information and/or cell handover success report advisable indication information.

Illustratively, before step 203, the terminal device performs a procedure of establishing a radio link and/or performs a procedure of cell handover, and collects and records corresponding data items according to the data collection indication information, so as to obtain a radio link failure report and/or a cell handover success report.

The second message is used to inform the network device that a radio link failure report and/or a cell handover success report is desirable.

Step 204: the network device sends a second message response message to the terminal device, wherein the second message response message comprises indication information for reporting a radio link failure report and/or indication information for reporting a cell switching success report.

The second message response message is used for indicating the terminal equipment to report the first message.

Illustratively, steps 201, 202, 203, 204 are optional steps.
