Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The background art related to the present invention is described below.

(1) Random access procedure

After the cell search procedure, the UE has acquired downlink synchronization with the cell, and thus the UE can receive downlink data. However, the UE can perform uplink transmission only if it acquires uplink synchronization with the cell. The UE establishes a connection with the cell through a Random access procedure (Random access procedure) and acquires uplink synchronization.

There are 2 different ways of random access procedure:

1. based on Competition (CBRA), as shown in fig. 1, the main process is as follows:

message one (Msg 1): the UE selects a Random Access preamble (preamble) and a Physical Random Access Channel (PRACH) resource and transmits the selected Random Access preamble to the base station by utilizing the PRACH resource;

message two (Msg 2): a Random Access Response (RAR) message, monitoring a Random Access reply, and monitoring a Physical Downlink Control CHannel (PDCCH) by the UE in a window to receive a corresponding Random Access reply;

message three (Msg 3): the UE sends the uplink transmission on an uplink grant (UL grant) specified by Msg 2. There may be different signaling content for different scenarios, e.g., Radio Resource Control (RRC) reestablishment request/RRC establishment request/system information request, etc.;

message four (Msg 4): and the UE can judge whether the random access is successful according to the Msg 4.

2. Based on non-Contention (CFRA), as shown in fig. 2, the main process is as follows:

msg 0: dedicated preamble and dedicated resource allocation for random access (RRC reconfiguration message);

msg 1: the UE selects a proper random access preamble and a PRACH resource according to a self measurement result (Synchronization Signal Block (SSB)/Channel State Information Reference Signal (CSI-RS) Index and the like) and a selection criterion, and transmits the selected random access preamble to the base station by utilizing the PRACH resource;

msg 2: and monitoring the random access reply, wherein the UE monitors the PDCCH in the window to receive the corresponding random access reply.

(2) Reference signal for NR measurement

The reference signal for NR measurement is divided into SSB and CSI-RS.

(3) Private/public random access

The handover command contains at least a cell identity of the target cell and a RACH configuration related to a beam (beam) configuration.

The UE selects a survivable beam from all beams of the target cell.

If the CFBA resources are not provided for the beam selected by the UE, the UE performs CBRA on the selected beam.

The target cell's Beam's common RACH configuration is associated only with SSBs. The network may have a dedicated RACH configuration (SSB/CSI-RS ID, dedicated RACH resource, dedicated preamble, etc.) related to the SSB or CSI-RS within one cell. The target cell may include, in order to enable the UE to access, one of the following RACH configurations in the RRC reconfiguration command:

a common RACH configuration;

a common RACH configuration and a dedicated RACH configuration associated with the SSB;

a common RACH configuration and a dedicated RACH configuration associated with the CSI-RS;

the dedicated RACH resources associated with the measurement result measured on the NR-SS or CSI-RS have a higher priority if the measurement result is above a threshold. If the measurement result of the SSB/CSI-RS corresponding to the configured dedicated RACH resource exceeds a set threshold, the dedicated resource is directly used for CFRA, and the UE does not use the common RACH resource for CBRA; the NR-SS/CSI-RS threshold, related resources, and related preamble may be configured in the handover command.

(4) Dual connection architecture

In a dual connectivity architecture, a UE may have one MN and one or more SNs. Both MN and SN can be LTE/e-LTE/NR nodes. When the network decides to add/replace a SN to the UE or to modify the SCG radio resource configuration for the SN, a random access procedure for the SN needs to be initiated if the SN's resources need to be used.

The following takes the SN addition process as an example:

step 1-2: MN sends SN adding request and relative reply message to SN;

step 3-5: the MN sends RRC reconfiguration information to the UE, relevant reply information from the UE to the MN, and relevant reconfiguration finishing information from the MN to the SN. The RRC reconfiguration message carries SN-related configuration parameters, and if the SCG radio resource configuration is included, step 6 is executed;

step 6: if a bearer requiring the use of SCG radio resources is configured, the UE needs to synchronize with a Primary serving Cell (PSCell) of the SN, that is, initiate random access to the network.

Step 7-12: state transfer between MN and SN and core network node, data forward transfer and path conversion.

In step 6, the UE initiates random access to the SN, and may initiate non-contention random access based on the dedicated RACH resource and preamble (possibly associated with the SSB or CSI-RS) allocated in the RRC reconfiguration message in step 3, or initiate contention-based random access using the common RACH resource given in the RRC reconfiguration message and selecting one available preamble.

The content in this step 6 can also be used to:

replacement of SN, or

The SN internally adjusts the SCG radio resources (SN modification).

These two flows may be initiated by the MN or by the SN.

(5) Uplink (UL) and Supplemental Uplink (SUL)

The higher frequency used by NR systems may result in a smaller coverage. To supplement the coverage, the network may configure two sets of UL and SUL parameters for the uplink of the UE. For either Frequency Division Duplex (FDD) or Time Division Duplex (TDD), the UE may be configured with an additional SUL to ensure coverage. Wherein the coverage of the SUL is greater than the coverage of the UL.

And when the downlink measurement quality of the UE on the UL carrier is lower than a network broadcast threshold, using the SUL carrier and the related configuration for random access. Once starting, all uplink transmissions of this random access can only be sent on the selected SUL frequency point.

(6) Bandwidth slicing (BWP, Bandwidth Part)

Under the adaptive Bandwidth (BA) technique, the reception and transmission bandwidths of the UE do not need to be as large as the Bandwidth of the cell, and are also set to be configurable. A subset of all the bandwidth of a cell is called BWP.

The BWP of the UE initially accessing the cell is initial BWP, which is commonly visible for idle UE and connected UE, and the initial BWP generally has a narrower bandwidth. After the UE enters the connected state, the network may allocate other uplink and downlink BWPs to the UE, and only the connected UE is available. And after receiving the synchronous reconfiguration message, the UE initiates the BWP of random access to be an uplink firstActiveBWP.

The invention provides an information reporting method, an information acquisition method, a terminal and network equipment, aiming at the problem that the reliability of network communication cannot be ensured because the content of SN (service provider) random access success and/or failure is not recorded and reported in the prior art.

As shown in fig. 4, an information reporting method according to an embodiment of the present invention is applied to a terminal, and includes:

step 41, recording the reported information of the target access state of the auxiliary node in the random access process of the terminal and the auxiliary node;

it should be noted that the target access status is access success or access failure.

Step 42, sending the reported information to a network device;

it should be noted that the report information includes: at least one of beam related information, resource related information, cell related information, location information of a terminal, and time related information.

The following describes specific contents contained in the report information.

Information related to beam

It should be noted that the beam related information includes at least one of the following information:

a11, first beam information;

it should be noted that, when the target access state is an access failure, the first beam information is beam information in which the terminal fails, where the beam information is specifically identification information of a beam, for example, an index of the beam.

A12, measurement information of the beam of the first cell;

it should be noted that the first cell includes: the terminal initiates a cell which is randomly accessed under the auxiliary node; further, the first cell further includes: and the terminal initiates the adjacent cell of the cell which is randomly accessed under the auxiliary node.

It should be noted that the NR system introduces information of beam (beam) level, and uses SSB and CSI-RS as measurement reference symbols.

In the SN adding process, the SN changing process or the SN modifying process, the terminal may initiate an access requirement to the SN or respond to a reconfiguration requirement of the network through random access. If an access failure occurs, the terminal may record the following:

a1, beam information when the terminal fails, and measurement results for the beam;

a2, recording SN target cell measurement results of failures before the failures by the terminal, wherein the SN target cell measurement results include RSRP and RSRQ (the RSRQ values are related to type), and related beam level measurement results include measurement results based on SSB and CSI-RS;

a3, each service cell measurement result before the terminal fails, including RSRP and RSRQ (RSRQ value is related to type), and possible beam level measurement results, including measurement results based on SSB and CSI-RS;

a4, measuring the results of each neighboring cell, including each access network type (RAT);

further, after receiving the measurement result of the beam level related to the access failure, the related network side may be used for adjusting the configuration parameters related to the beam, for example, preamble (preamble) and RACH resource configuration associated with the beam; or reporting to a data collection node (TCE) for the purpose of carrying out big data statistics and the like by an operator.

Second, resource-related information

It should be noted that the resource-related information includes at least one of the following information:

b11, preamble used by the terminal and Random Access Channel (RACH) resource information;

b12, sending lead code times;

b13, indication information whether the maximum transmission power of the preamble is reached;

b14, indication information whether competition has occurred.

It should be noted that, after receiving the measurement result record, the relevant network side may be used to adjust configuration parameters related to the RACH, such as preamble allocation, RACH resource configuration, and the like.

The network may configure the terminal with the random access parameters in one of the following manners:

b1, common RACH configuration;

b2, common RACH configuration and dedicated RACH configuration associated with SSB;

b3, common RACH configuration and dedicated RACH configuration associated with CSI-RS;

if the network configures the terminal with both public and private RACH configuration information, the terminal needs to automatically determine whether to use the public RACH for CBRA or use the private RACH configuration associated with a certain SSB/CSI-RS for CFRA based on its own beam level measurement result and a reference threshold of the network configuration, and therefore needs the UE to report actually used RACH-related parameters including CFRA/CBRA, used preamble and transmission frequency, whether the maximum transmission power is reached, and actually used RACH resource information, etc.

After receiving the preamble and RACH resource information actually used in connection with the access failure or access success, the relevant network side may be configured to improve the RACH resource configuration scheme, for example, change a reference threshold value configured for the terminal to use the dedicated RACH resource, and the like; or report to the TCE for the operator to perform big data statistics and other purposes.

It should be further noted that, when the target access status is access failure, the resource-related information includes at least one of the following information:

b21, carrier information of access failure;

it should be noted that the carrier information may be an UL carrier used by the terminal, or an SUL carrier used by the terminal. Specifically, the network notifies the terminal to use UL or SUL after requesting the terminal to access in the synchronization reconfiguration message used for random access. If the terminal does not record and report after the access failure occurs, the network side may send other configuration information to the UE and delete the configuration information causing the failure. Therefore, the terminal records the carrier information when the access fails, and is beneficial to judging the failure reason and adjusting the parameters after the subsequent network side receives the carrier information.

B22, random access priority related information used by the terminal;

specifically, the random access priority related information includes: power boost step size information and/or backoff indication information.

The power ramping stephiphigh priority pointer has a power ramping stepsize for transmitting the preamble for random accesses of different priorities; the backspacing indicator information (scalingfactory bi) pointer has a backspacing indication for different priority random accesses, and the specific content of the backspacing indication is a scaling factor used for backspacing.

B23, the first active bandwidth fragmentation for which an access failure occurred.

It should be noted that, the network notifies the terminal to notify the synchronous reconfiguration message used for random access, that is, to notify the first activated BWP (first active BWP) used after the UE accesses, where the BWP may be another BWP that does not overlap with the initial BWP. If the terminal does not record and report after the access failure occurs, the network side may send other configuration information to the terminal and delete the configuration information causing the failure. Therefore, the terminal records the firstActiveBWP when the access fails, and the subsequent network side is facilitated to judge the failure reason and adjust the parameters after receiving the failure reason.

After receiving the carrier/BWP record related to the access failure, the relevant network side may use the configuration parameters to improve the synchronous reconfiguration, for example, report the configuration parameters to a data collection node (TCE) for the purpose of operator big data statistics.

In addition to the carrier/BWP information, if the terminal recording and reporting are not performed immediately after the access failure, more parameters may need to be recorded by the terminal itself and reported to the network in the subsequent process. For example, information related to the priority of random access used for random access, etc., all of which are helpful for the network to determine the reason of access failure and guide subsequent configuration or resource allocation adjustment.

Third, cell related information

It should be noted that, when the target access status is access failure, the cell-related information includes at least one of the following information:

c1, identification information of the cell with access failure;

c2, registering Public Land Mobile Network (PLMN) where access failure occurs;

c3, measuring result of service cell before access failure;

c4, measurement results of other cells except the serving cell before access failure.

Fourthly, position information of terminal

It should be noted that the location information Of the terminal refers to the geographical location information Of the terminal, for example, the downlink Time Difference Of Arrival (OTDOA) positioning result, the horizontal and vertical positioning result, or the Global Navigation Satellite System (GNSS) positioning result, etc., and the node for which the failure occurs adjusts the parameters related to the location information, such as the number Of SSBs, the antenna position/antenna tilt angle, the transmission power, or the big data statistics requirement Of the data collection node/operator, etc.

Fifth, time related information

It should be noted that the time-related information is mainly content that is recorded only when the target access state is access failure, and the time-related information includes: and the time interval between the access failure moment and the failure reporting moment, wherein the time related information is mainly used for assisting the receiving node to search for the failure node, judging the data validity and the like.

It should be further noted that, one sending method of the report information is as follows:

It should be noted that, because the amount of information recorded by the terminal is huge, and the SCGFailureReport only needs to report information that helps the network side to quickly establish a new SN connection to the terminal after the SN connection fails, the reported information of the SN access failure or the SN access success can be stored in the terminal, and the available indication information is reported to the network side after the storage. Because the current record is for the SN, the terminal remains connected to the MN, so the terminal can directly carry the available indication in all the next available uplink RRC messages of the MN, or carry the available indication in any procedure of cell replacement/connection establishment or recovery/reestablishment, or send the available indication to the SN for the case of successful access. The available indication information may only occupy 1bit, and is used to notify the network side that the terminal stores the related access failure or access success report information, or distinguish the access success report information and the access failure report information to respectively indicate. And when the network side needs the report information of the access failure or the access success, sending a downlink signaling request report to the UE. The UE may carry all the related record contents (i.e., report information) of access failure or access success in the lower priority uplink information.

If the network side does not immediately require the UE to report after the terminal reports the available indication information, the UE keeps the access failure/success record for a period of time and can control the access failure/success record through a timer. For example, if the network has not requested to report for more than 3 hours, the terminal deletes the stored report information of the access failure or access success by itself.

It should be further noted that, when the target access status is access failure, another sending method of the report information is as follows:

It should be noted that, in the event of SCG failure, the protocol has introduced SCGFailureReport signaling, which is used for the UE to notify the network of the failed link information through the failed link, so that the network can rapidly configure a new link for the UE to continue data transmission. Therefore, one possible reporting method is: the reported information of access failure for the SN recorded by the UE may be notified to the MN network side or other SN network sides that have not failed through the SCGFailureReport signaling.

It should be noted here that, when the terminal is successfully accessed, it indicates that the terminal is connected to the secondary node, and at this time, the reported information may be directly sent to the secondary node or sent to the master node, that is, the network device refers to the secondary node and/or the master node; and when the terminal fails to access, it indicates that the terminal does not establish connection with the secondary node, and at this time, the terminal can only communicate with the primary node.

Since the reported information is the record of the access failure or access success of the terminal for the access node B, the node a on the network side, which receives the record of the terminal, may not be the node B in which the access failure or access success occurs. For this case, two processing methods follow:

the first method is as follows: if the set terminal record information aiming at access failure or access success can not be used for configuration/resource adjustment of the base station side, the node A of the receiving network side does not need to analyze the terminal record content and is directly reported to the TCE by the receiving node A for the operator to carry out big data statistics and operator decision judgment;

the second method comprises the following steps: if the set terminal record information aiming at the access failure or the access success can be utilized by the node B of which the terminal fails, such as the adjustment of configuration parameters at the base station side, the adjustment of resource scheduling, the adjustment of beam information and the like, the node B of the network side of which the terminal indicated in the report information has a problem can be preliminarily analyzed by the node A, and the record content is sent to the node B of which the UE has failed to access or has successful to access. The node B may use the recorded content to perform base station related optimization, and/or report to the TCE for the operator to perform big data statistics and operator decision making.

According to the embodiment of the invention, the reported information aiming at the target access state of the auxiliary node is recorded in the random access process of the terminal and the auxiliary node, and the reported information is sent to the network equipment, so that the communication flow of a 5G and subsequent communication systems is improved, and the reliability of network communication is ensured.
