In some embodiments, the terminal may make small data transmissions SDT. The SDT may be performed when the terminal is in a non-connected state, for example, the non-connected state may include an RRC inactive (inactive) state, and may also include an RRC idle state.

For example, when the terminal in rrc_inactive state needs to transmit small uplink data and certain conditions are met, the terminal initiates a 4-step random access (4-step RACH) or 2-step random access (2-step RACH) procedure according to the configuration of the base station, or configures grant transmission SDT message by using a physical uplink shared channel (PUSCH Type 1) of Type 1, and after less signaling interaction between the terminal and the base station, the terminal can perform small data transmission in rrc_inactive state. In this process, the terminal is maintained in the rrc_inactive state without switching to the CONNECTED (rrc_connected) state, so as to achieve the goal of reducing transmission delay and signaling overhead.

The small data transmission initiated by the terminal in the RRC_INACTIVE state can be realized based on the following two schemes according to different channel resources adopted by the first uplink data transmission of the terminal:

scheme 1: uplink small data transmission based on RACH mechanism (hereinafter referred to as RA-SDT, RACH-Small Data Transmission). Scheme 1 reuses and enhances random access procedure and terminal in RRC_INACTIVE state initiates small data transmission using resources such as Msg A of 2-step RACH or Msg3 of 4-step RACH

Scheme 2: uplink small data transmission (CG-SDT, configured Grant-Small Data Transmission) of Grant resources is Configured based on PUSCH. Scheme 2 reuses and enhances the PUSCH Type 1 configuration grant mechanism, and the terminal in the rrc_inactive state initiates small data transmission by using PUSCH channel Type 1 configuration grant resources.

Before the terminal initiates the SDT small data transmission process, the base station needs to configure resources for the terminal. For RA-SDT, resources are configured by the base station to the terminal through system information. For CG-SDT, the PUSCH channel Type 1 configuration authorized resource is configured to the terminal by the base station through RRC dedicated signaling.

Under the condition that the SDT process is initiated, the terminal in the RRC_INACTIVE state initiates the SDT process, and a first SDT message is sent by utilizing resources configured by the base station, wherein the first SDT message comprises RRC signaling (such as RRCResumeRequest message), uplink small data sent by the terminal and the like.

For example, the SDT procedure is triggered in response to all of the following conditions being met:

the higher layer requests RRC connection restoration;

SIB1 contains SDT public configuration;

configured with SDT configuration;

the undetermined data in all the uplink are mapped to the radio bearer configured to the SDT;

for reduced capability (Reduced Capability, redcap) terminals, when the Redcap specific initial downstream Bandwidth portion (BWP) contains non-Cell definition synchronization broadcast signal blocks (SSB, synchronization Signal/Physical Broadcast Channel Bloc, CD-SSB), ncd-SSB-Redcap synchronization BWP-SDT is configured.

The lower layer indicates that the condition of the initial SDT as described in TS 38.321[3] is satisfied.

Regarding the SDT procedure, after the terminal sends the first SDT message, the terminal continues to be in the rrc_inactive state. Under the control of the base station, the downlink and uplink small data transmission can be continued between the terminal and the base station.

Normally, the base station sends an RRC signaling (e.g., RRCRelease message) to the terminal to terminate the SDT procedure, and the terminal is still in rrc_inactive state; some abnormal situations will also terminate the SDT process.

For the two schemes, namely RA-SDT and CG-SDT, the resources used for the first data transmission are different, so that the specific schemes have differences, such as configuration of SDT resources, resource selection for transmission of the 1 st SDT message (also called initial SDT message), subsequent uplink and downlink data transmission modes between the terminal and the base station, and the like, and specific analysis is carried out below.

RACH resources for SDT or PUSCH channel Type1 configuration grant resources may be configured on a conventional UL or SUL (supplementary uplink, supplemental uplink) carrier.

For CG-SDT, when the terminal enters an RRC_INACTIVE state from an RRC_CONNECTED state, the base station configures the PUSCH Type1 configuration authorized resource to the terminal through RRC signaling. Based on the Type1 configuration authorization mechanism of reuse 5G R15/R16, parameters such as an RSRP change threshold for time alignment verification, an SSB-RSRP (Reference Signal Receiving Power, reference signal received power) threshold for beam selection, a timer for maintaining time alignment and the like are required to be configured for the terminal aiming at CG-SDT.

For RA-SDT, the base station configures SDT transmission resources on RACH through system information SIB 1. The base station may configure the terminal to employ a 2-step RACH or a 4-step RACH, or to configure both a 2-step RACH and a 4-step RACH. For 2-step RACH or 4-step RACH, parameters to be configured in the system information include SSB selection related parameters, power control related parameters, parameters related to RACH preamble groups, and the like. In PRACH resource allocation, the random access procedure for RA-SDT may use a different RO (RACH channel opportunity) than the random access procedure for other purposes (e.g., handover), and may also share the RO. The RA-SDT resource only supports configuration on the initial BWP. In addition, the RA-SDT only supports the contention based random access scheme, and does not support the non-contention based random access scheme.

When a terminal in an RRC_INACTIVE state initiates an SDT process, SDT resources are required to be selected according to a determined rule, and the specific selection mode is as follows:

step 1: an uplink carrier is selected. The SUL carrier is preferentially selected and the regular uplink carrier is secondarily selected. The terminal selects the SUL carrier if the SUL carrier is configured for the terminal and the RSRP measured by the terminal is below a threshold configured by the base station, otherwise selects the regular uplink carrier.

Step 2: CG-SDT or RA-SDT resources are selected. If CG-SDT resources are configured on the selected uplink carrier, type 1 configuration grant resources are valid, and the RSRP of at least one of the SSBs associated with the CG-SDT resources is above the SSB-RSRP threshold for beam selection described above, the terminal initiates a CG-SDT procedure on the selected uplink carrier. Otherwise, if the RA-SDT resource is configured on the selected uplink carrier, the terminal initiates an RA-SDT procedure on the selected uplink carrier.

In selecting RA-SDT, the rules determined when introducing 2-step RACH are reused to further select 2-step RA-SDT or 4-step RA-SDT. Namely, when the uplink carrier is simultaneously configured with 2-step RA-SDT and 4-step RA-SDT resources, the terminal selects according to an RSRP threshold configured by the base station, and when the RSRP measured by the terminal is higher than the threshold, the terminal selects 2-step RA-SDT; otherwise, 4-step RA-SDT is selected.

Initiating an SDT process by using CG-SDT resources: considering the design of multiple SSB beams in a 5G supporting cell, in order to enable a terminal to select an SSB beam with better signal when initiating a CG-SDT process, an association relationship is established between CG-SDT resources and SSBs, and the CG-SDT resources are associated with a group of SSBs through RRC signaling configuration. The base station also configures the terminal with an SSB-RSRP threshold for beam selection. When a terminal initiates a CG-SDT process and subsequently uses CG-SDT resources to carry out uplink transmission, selecting an SSB wave beam with the measured RSRP higher than the threshold value, selecting CG-SDT resources associated with the SSB wave beam, and sending the 1 st uplink message of the SDT on a PUSCH channel.

Initiating an SDT procedure using a 2-step RA-SDT resource: the terminal uses a 2-step RACH procedure to send the 1 st uplink message of the SDT in the MsgA. The terminal may fall back from the 2-step RA-SDT to the 4-step RA-SDT procedure after the terminal has initiated the 2-step RA-SDT, when the terminal has received a random access back-off indication in the MsgB, or when the MsgA has repeated transmission more than a certain number of times.

Initiating an SDT procedure using a 4-step RA-SDT resource: the terminal uses 4-step RACH procedure to send the 1 st uplink message of SDT in Msg 3.

The 1 st uplink message of the SDT may include, in addition to RRC signaling (e.g., rrcreseumerequest message), content such as application data of the terminal according to the size of data that can be transmitted by the message. The function of the RRC signaling is to provide the necessary information such as the identification of the terminal to the base station, so that the base station can configure the SDT process of the terminal.

The terminal in rrc_inactive state needs to perform data transmission through signaling interaction with the base station (including the terminal sending a rrcreseumerequest message to the base station, the base station then sending a rrcreseume message to the terminal, etc.), after the terminal and the base station complete necessary resource configuration and switch to rrc_connected state. In contrast, by adopting the 5G SDT enhancement technology, the terminal can send uplink data to the base station in the 1 st uplink message of the SDT, thereby reducing the time delay of data transmission and the overhead of air interface signaling.

The terminal is still in the RRC_INACTIVE state after initiating the SDT process, and uplink and downlink data transmission can be continued between the terminal and the base station without switching to the RRC_CONNECTED state.

For CG-SDT, after the primary PUSCH transmission, the base station may dynamically authorize and schedule subsequent uplink transmission, and the terminal may also configure an authorized resource opportunity for uplink transmission in the subsequent PUSCH Type 1, and the base station dynamically allocates resources for downlink small data transmission. When the PUSCH Type 1 is used for configuring the authorized resource opportunity for subsequent uplink transmission, the terminal selects the SSB beam and CG-SDT resources associated with the SSB beam in the same manner as when the SDT procedure is initiated, and performs uplink data transmission.

For RA-SDT, after the initial PUSCH transmission (i.e., msg3 or MsgA) and the random access procedure are completed, the base station may schedule subsequent uplink and downlink data transmissions using dynamic uplink grants and downlink allocations.

For CG-SDT, when the Type 1 configured grant resource is used for performing primary PUSCH transmission and subsequent uplink transmission, the terminal needs to determine whether the configured grant resource is valid, so as to ensure that data transmission is successfully performed. For example, a mechanism based on a combination of a timer and an RSRP change threshold may be employed for authentication. At the MAC (Media Access Control, medium access control) layer, a timer for maintaining time alignment is introduced, and when the terminal receives the configuration of the timer by the base station through RRC signaling, the timer is started, and before the timer expires, the terminal regards the uplink transmission of the CG-SDT as time alignment with the base station, and the CG resource is valid. And the terminal restarts the timer after receiving a Timing Advance (TA) adjustment instruction sent by the base station through the MAC layer. If the timer times out, the terminal considers that the CG resource is not valid any more and releases the resource. In addition, the terminal performs time alignment verification based on the RSRP, that is, if the terminal measures that the variation of the RSRP value exceeds the RSRP variation threshold set by the base station, the CG resource is not valid any more compared with the last uplink transmission.

The SDT process will continue after start-up, stopping SDT delivery when at least one of the following is satisfied:

SDT was successful. For example, the base station informs the terminal to stop the SDT process through RRC signaling (e.g., RRCRelease message), or the base station controls the terminal to switch to rrc_idle or rrc_connected state through RRC signaling, in the SDT process, the base station may switch the terminal from the SDT process to non-SDT process, for example, in the case that the amount of data to be transmitted increases, etc., the base station may switch the terminal to rrc_connected state through RRC signaling, so that the terminal performs data transmission in rrc_connected state.

SDT fails. For example, a cell reselection occurs, the SDT failure detection timer expires, the MAC entity reaches a configured maximum PRACH preamble transmission threshold, the RLC entity reaches a configured maximum retransmission threshold, and the SDT is considered to fail if the SDT specific time alignment timer expires when the SDT procedure is ongoing on the CG and the UE does not receive a response from the network after the initial PUSCH transmission.

Therefore, the terminal in the RRC_INACTIVE state can be kept in the RRC_INACTIVE state from the initiation of the SDT process to the termination of the SDT transmission, so that repeated conversion of the terminal between the RRC_INACTIVE state and the RRC_CONNECTED state is avoided, and the air interface signaling overhead of intermittent small data transmission is reduced.

As shown in fig. 2, the information transmission method may include the steps of:

in step S201, the terminal transmits a first indication to the first node.

For example, when the network node includes the first node, the terminal only needs to determine whether the first node belongs to a predetermined network.

In other embodiments, the second indication may be different from the first indication, e.g. the first indication comprises a type of the first information, an availability indication of the first information, and the second indication may comprise indication information for instructing the second node to perform a terminal context relocation.

In some embodiments, reference may be made to alternative implementations described before or after the description corresponding to fig. 2.

In a first aspect, embodiments of the present disclosure provide an information transmission method. Fig. 3 is a schematic flow chart diagram illustrating a method of information transmission according to an embodiment of the present disclosure. The information transmission method shown in the present embodiment may be performed by a terminal.

As shown in fig. 3, the information transmission method may include the steps of:

in step S301, a first indication is sent to a network node (which may also be referred to as a network device) in a non-connected state, wherein the first indication is used by the network node to determine whether to obtain the first information.

It should be noted that the embodiment shown in fig. 3 may be implemented independently or in combination with at least one other embodiment in the disclosure, and specifically may be selected as needed, which is not limited by the disclosure.

It should be noted that the first indication is used for assisting the network node in determining whether to acquire the first information, but is not used for deciding whether the network node acquires the first information, and correspondingly, the network node may consider the first indication or may not consider the first indication when determining whether to acquire the first information.

In some embodiments, the first information may include information determined based on the first operation. Of course, the first information is not limited thereto, and may include information stored in a terminal or information arranged in a terminal in other cases. The following embodiments mainly exemplify the technical solutions of the present disclosure when the first information includes information determined based on the first operation.

In some embodiments, the first operation includes at least one of:

self-organizing networks (Self-Organizing Network, SON);

minimization of drive tests (Minimization Drive Test, MDT).

In some embodiments, the network node may include a first node that receives the first indication, and may also include a second node that has a communication interface with the first node. For example, the network node may comprise a base station, e.g. referred to as a gNB, the first node may comprise a receiving base station (receiving gNB), and the second node may comprise a last serving base station (last serving gNB).

In some embodiments, the MDT includes at least one of: log (logged) MDT, immediate (Immediate) MDT.

In some embodiments, the logged MDT includes at least one of: signaling-based logged MDT, management-based logged MDT.

In some embodiments, the information sending method further includes: the first information is sent to a network node.

For example, the network node determines that the first information needs to be acquired, and the network node may send a request to the terminal, where the request is used to request the terminal to send the first information to the network node, and after receiving the request message, the terminal may send the first information to the network node. Of course, in other embodiments, the terminal may also autonomously send the first information to the network node without receiving the request message.

In some embodiments, for example, the first information includes information determined by the terminal based on SON and/or MDT, the process of the base station sending a request message to the terminal and obtaining the first message may be referred to as report retrieval, and the first information sent by the terminal to the network node may be referred to as reporting.

In some embodiments, the first indication and/or the first information is sent by at least one of:

a radio resource control RRC (Radio Resource Control) message;

Small data transfer SDT (Small data transmission) message.

For example, the terminal may send the first indication and/or the first information to the network node through an RRC message. In some embodiments, the RRC message includes an RRC resume request (rrcresemerequest) message, although the RRC message is not limited thereto and may be other RRC messages capable of being sent to the network node in a non-connected state.

For example, the terminal may send the first indication and/or the first information to the network node through an SDT message, which may be sent in a non-connected state. In some embodiments, the SDT message includes at least one of: an initial SDT message; non-initial SDT message. The SDT message may also be referred to as SDT signaling, where the SDT message may carry, in addition to the first indication and/or the first information, small uplink data that needs to be sent to the network node in the SDT procedure.

In some embodiments, the terminal may perform the logged MDT in the unconnected state, and store the first information obtained by the measurement record in the reserved memory, and when the reserved memory is full, the terminal will stop recording, and delete the stored first information after a period of time (may be determined based on configuration or a protocol contract, for example, may be 48 hours).

As can be seen, for the first information obtained based on the logged MDT measurement record, if the terminal fails to report to the network node in time within a period of time, the first information will be deleted, which results in resource waste in the measurement process.

According to the embodiment of the disclosure, after the terminal stores the first information obtained based on the logged MDT measurement record in the reserved memory, the terminal may not need to wait until entering the connected state and then send the first indication and/or the first information to the network node, but may send the first indication and/or the first information to the network node in the non-connected state.

For example, under the condition that the terminal sends the first indication to the network node in a non-connection state, the network node is favorable for ensuring that whether the first information needs to be acquired or not is timely determined according to the first indication, and further the terminal is favorable for ensuring that the terminal sends the first information to the network node timely; for example, when the terminal sends the first information to the network node in the non-connection state, it is beneficial to ensure that the network node timely acquires the first information. Both the two cases are beneficial to ensuring that the terminal timely sends the first information to the network node, so that the problem of resource waste caused by deleting the first information is avoided.

In some embodiments, the SDT message is sent by at least one of: signaling radio bearer SRB (Signalling Radio Bearer); SRB2; newly defined SRBs.

In some embodiments, the terminal sends the first indication and/or the first information to the network node through the SDT message, but the current SDT only supports configuration SRB2, that is, the SDT message can only be carried through SRB2, and the first indication and/or the first information is carried through SRB 1.

For example, when the SDT message is carried through the SRB1, the SRB of the configuration supported by the SDT may be extended, and the SDT may support not only the configuration SRB2 but also the configuration SRB1, so that the SDT may be carried through the SRB1, and the SRB1 may also carry the first indication and/or the first information in the SDT message.

For example, when the SDT message is carried by the SRB2, since the SDT message may carry the first indication and/or the first information, the first indication and/or the first information may be extended to support the configured SRB, and the first indication and/or the first information may support not only the configuration SRB1 but also the configuration SRB2, so that the first indication and/or the first information may be carried and sent in the SDT message carried by the SRB 2.

For example, SRBs may be newly defined, e.g., referred to as SRBx, where x is a value other than 1 and 2, and SRBx may be designed to carry both SDT messages and the first indication and/or the first information.

In some embodiments, the first indication and/or first information is sent over SRB1/SRBx or the first indication and/or first information supports SRB2 sent over existing configuration to SDT flows.

Specifically, the terminal carries the first indication and/or the first information in the uplink SDT signaling, where the SDT is configured to be sent through SRB1, or the first indication supports to be sent through SRB 2. The network node carries a report request message in the downstream SDT signaling, the SDT being configured to be sent over SRB1, or alternatively, the first indication and/or the first information request message support to be sent over SRB 2.

In some embodiments, the first indication comprises at least one of:

the type of the first information;

a type of configuration for acquiring the first information;

an availability indication of the first information;

an availability indication of the configuration;

effective indication information of the first information;

effective indication information of configuration;

memory space information of the terminal, which in some embodiments may be used by the second node to determine whether to perform terminal context relocation; in some embodiments, the storage space information of the terminal may be used for the first node to configure an uplink grant (UL grant) for the terminal to transmit the first information.

For example, the type of first information includes at least one of: access type, traffic type, report type.

The access type includes at least one of: new Radio, NR), long term evolution (Long Term Evolution, LTE).

The service type may be a service type associated with the first information recorded by the terminal, for example, including at least one of: audio service, video service, voice service, broadcast service, multicast service, slice service.

The report type includes at least one of: SON report, MDT report, logged MDT report, immediate MDT report, signaling-based logged MDT report, management-based logged MDT report.

For example, the type of configuration includes at least one of: SON configuration, MDT configuration, logged MDT configuration, immediate MDT configuration, signaling-based logged MDT configuration, management-based logged MDT configuration.

For example, the availability indication may include at least one of: usable or unusable.

For example, the valid indication information may include at least one of: effective time, effective area, duration for reporting maintenance, duration for reporting remaining maintenance.

For example, the storage space information includes at least one of: the amount of space occupied by the stored report, the amount of space remaining for storing the report.

In some embodiments, based on the first indication, the network node may determine an urgency to acquire the first information, when determining that acquiring the first information is relatively urgent, the network node may determine that the first information needs to be acquired, when determining that acquiring the first information is relatively unoccupied, the network node may determine that the first information is not acquired.

For example, the first indication comprises storage space information, the network node determines that the remaining space for storing the report is relatively small based on the storage space information, and the terminal may delete the first information in a short time, so that it may be determined that acquiring the first information is relatively urgent, and may further determine that acquiring the first information is required.

For example, the first indication comprises a type of the first information, the network node determines that the type in the first information is a signaling-based logged MDT report, and for the signaling-based logged MDT report, the first information is deleted within a period of time after the storage space of the terminal is full, so that the network node may determine that acquiring the first information is relatively urgent, and may further determine that the first information needs to be acquired.

In some embodiments, based on the first indication, the network node may determine that the first information is valid, when it is determined that the first information is valid, the network node may determine that the first information needs to be acquired, when it is determined that the first information is invalid, the network node may determine that the first information is not acquired.

For example, the first indication comprises an availability indication of the first information, and if the network node determines that the first information is not available according to the first indication, it may be determined that the first information is not to be acquired, and if the network node determines that the first information is available according to the first indication, it may be determined that the first information is to be acquired.

For example, the first indication includes effective area information of the first information, if the network node determines that the terminal is located outside the effective area according to the first indication, it may be determined that the first information is not available, it may be determined that the first information is not required to be acquired, and if the network node determines that the terminal is located inside the effective area according to the first indication, it may be determined that the first information is available, it may be determined that the first information is acquired.

In some embodiments, sending a first indication to a network node in a non-connected state comprises: the network node belongs to a predetermined network and sends a first indication to the network node in a non-connected state.

For example, before the terminal sends the first indication to the network node in the non-connected state, it may be determined whether the network node belongs to a predetermined network, where the terminal sends the first indication to the network node in the non-connected state only if the network node belongs to the predetermined network, and where the terminal does not send the first indication to the network node in the non-connected state if the network node does not belong to the predetermined network.

Wherein, in some embodiments, the predetermined network may be characterized by the following network identifications; in some embodiments, the predetermined Network may include a Public Network, such as a Public land mobile Network (Public Land Mobile Network, PLMN), or may include a Non-Public Network (NPN), which may further include at least one of: independent Non-Public networks (SNPN), public Network integrated Non-Public networks (Public Network Integrated NPN, PNI-NPN).

For example, when the network node includes a first node and a second node, the terminal may only determine whether the first node belongs to a predetermined network, and when the first node belongs to the predetermined network, the terminal may send a first indication to the network node in a non-connected state; or, the terminal may only determine whether the second node belongs to a predetermined network, and when the second node belongs to the predetermined network, the terminal sends the first indication to the network node in the non-connection state; or, the terminal may determine whether the first node and the second node belong to a predetermined network, and when both the first node and the second node belong to the predetermined network, the terminal sends the first indication to the network node in the non-connected state.

In some embodiments, the terminal may also send the first indication to the network node in the non-connected state without determining whether the network node belongs to the predetermined network.

In some embodiments, the terminal performs a PLMN check to determine whether the first node and/or the second node belongs to a terminal stored PLMN.

If both belong, a first indication is sent. Otherwise, not transmitting; or if the first node belongs to the storage PLMN, the terminal sends a first instruction to the first node, further, the first node determines whether the second node belongs to the storage PLMN, if so, the first instruction is forwarded, and otherwise, the first instruction is not sent.

In some embodiments, sending a first indication to a network node in a non-connected state comprises: transmitting a first indication to the network node in the SDT procedure, wherein the terminal supports transmitting at least one of: a first indication; first information.

In case the terminal has the capability to send the first indication and/or the first information to the network node in the SDT procedure, the terminal may send the first indication and/or the first information to the network node in the SDT procedure, and since the SDT procedure is performed in the non-connected state, it may be achieved that the first indication and/or the first information is sent to the network node in the non-connected state.

In some embodiments, the method further comprises: transmitting capability information to the network node, wherein the capability information is used for indicating that the terminal supports at least one of the following to be transmitted to the network node in the SDT flow: a first indication; first information.

The terminal may send capability information to the network node, and indicate, to the network node, through the capability information, whether the terminal supports sending the first indication and/or the first information to the network node in the SDT procedure, and the network node may receive, in the SDT procedure, the first indication and/or the first information sent by the terminal if it is determined that the terminal supports sending the first indication and/or the first information to the network node in the SDT procedure.

In some embodiments, the first node may determine whether the terminal supports sending the first indication and/or the first information to the network node in the SDT procedure in combination with the capability of the terminal to support sending the first indication and/or the first information and the capability of the terminal to support SDT.

For example, a capability may be newly defined for characterizing whether the terminal supports sending the first indication and/or the first information to the network node in the SDT procedure.

Alternatively, the first node may determine, according to the capability of the existing terminal to support sending the first indication and/or the first information and the capability of the terminal to support SDT, whether the terminal supports sending the first indication and/or the first information to the network node in the SDT procedure. For example, the terminal supports sending the first indication and/or the first information, and the SDT is supported, it may be determined that the terminal supports sending the first indication and/or the first information to the network node in the SDT procedure, and if the terminal does not support sending the first indication and/or the first information, or does not support the SDT, it may be determined that the terminal does not support sending the first indication and/or the first information to the network node in the SDT procedure.

In a second aspect, embodiments of the present disclosure provide an information receiving method. Fig. 4 is a schematic flow chart diagram illustrating an information receiving method according to an embodiment of the present disclosure. The information receiving method shown in the present embodiment may be performed by a first node, and the first node may have a function of implementing the operations in the following embodiments.

As shown in fig. 4, the information receiving method may include the steps of:

In step S401, a first indication sent by the terminal in a non-connected state is received, where the first indication is used by the first node and/or the second node to determine whether to acquire the first information.

According to an embodiment of the disclosure, the network node may receive a first indication sent by the terminal in the non-connected state, which may be used to assist the network node in determining whether to obtain the first information. The first indication can be sent to the network node when the terminal is in the non-connection state, and the first indication does not need to be sent to the network node when the terminal is in the connection state, so that the network node can be ensured to be capable of timely determining whether to acquire the first information according to the first indication.

In some embodiments, the first operation includes at least one of:

self-organizing networks (Self-Organizing Network, SON);

minimization of drive tests (Minimization Drive Test, MDT).

In some embodiments, the MDT includes at least one of: logged MDT, immediate MDT.

In some embodiments, the information receiving further comprises: determining to acquire first information, and sending a request for acquiring the first information to the terminal; and receiving the acquired first information sent by the terminal.

In some embodiments, the first indication and/or report is sent by at least one of: an RRC message; SDT messages.

In some embodiments, the first indication comprises at least one of:

the type of the first information;

a type of configuration for acquiring the first information;

an availability indication of the first information;

an availability indication of the configuration;

effective indication information of the first information;

effective indication information of configuration;

and the storage space information of the terminal.

For example, the type of first information includes at least one of: SON report, MDT report, logged MDT report, immediate MDT report, signaling-based logged MDT report, management-based logged MDT report.

For example, the first indication comprises an effective area of the first information, if the network node determines that the terminal is located outside the effective area according to the first indication, it may be determined that the first information is not available, it may be determined that the first information is not required to be acquired, and if the network node determines that the terminal is located inside the effective area according to the first indication, it may be determined that the first information is available, it may be determined that the first information is acquired.

In some embodiments, the information receiving method further comprises: a second indication is sent to the second node, wherein the second indication is used by the second node to determine whether to perform a terminal context relocation (UE context relocation).

While the terminal is in the non-connected state, the first node may receive the first indication sent by the terminal, but the terminal context (context) may be stored in the second node, and when the first node is not the same node as the second node, the first node does not have the terminal context, so that the information from the terminal cannot be correctly parsed.

Thus, in this embodiment, the first node sends a second indication to the second node, which may be used by the second node to determine whether to perform terminal context relocation. Wherein the second node performs a terminal context relocation, may comprise sending the terminal context to the first node.

Wherein in some embodiments the second indication may be the same as the first indication, e.g. the first indication comprises a type of first information, an availability indication of the first information, then the second indication may also comprise a type of first information, an availability indication of the first information, the second indication may assist the second node in determining whether to perform a terminal context relocation. In other embodiments, the second indication may be different from the first indication, e.g. the first indication comprises a type of the first information, an availability indication of the first information, and the second indication may comprise indication information for instructing the second node to perform a terminal context relocation.

In some embodiments, the second indication is the same as the first indication, the terminal sends the first indication to a first node (receiving gNB) indicating that the terminal has a SON/MDT report or configuration available, and in response to receiving the first indication, the first node sends the first indication to a second node (last serving gNB), which determines whether to perform terminal context relocation.

In some embodiments, the terminal sends a first indication to a first node (receiving gNB) indicating that the terminal has a SON/MDT report or configuration available, in response to receiving the first indication, the first node determines whether to perform terminal context relocation and sends a second indication (e.g., directly indicating whether the second node performs terminal context relocation) to the second node, the second node determining whether to perform terminal context relocation based on the second indication.

For example, if the protocol commits that the second node needs to perform terminal context relocation if it receives the second indication, then the second node may perform terminal context relocation based on the protocol commitment if it receives the second indication.

For example, after receiving the second indication, the second node may determine whether to perform terminal context relocation based on its own policy. For example, the self-policy may be: and if the first information is larger than the data quantity threshold value, performing terminal context repositioning, otherwise, not performing terminal context repositioning. For example, the self-policy may be: the type of the first information has relatively high requirements on time delay, terminal context repositioning is performed, otherwise, terminal context repositioning is not performed. For example, the self-policy may be: the priority of the traffic of the first information is relatively high, and terminal context relocation is performed, otherwise, terminal context relocation is not performed. Of course, the own policy of the second node is not limited to the above-mentioned ones.

In some embodiments, in response to receiving the second indication, the second node determines to perform terminal context relocation in accordance with the protocol convention based on the second indication.

In some embodiments, in response to receiving the second indication, the second node determines whether to perform terminal context relocation in accordance with its own policy based on the second indication.

For example, it is determined whether to perform a context relocation based on the report size, if it is greater than a certain threshold, the context relocation is performed, otherwise, the context relocation is not performed.

For example, it is determined whether to perform a context relocation based on the traffic type or the report type, and the context relocation is performed for reporting of traffic association with high priority or emergency traffic or reporting latency requirements, otherwise, not performed.

The following describes exemplary execution and non-execution of terminal context relocation by several embodiments.

In some embodiments, the information receiving method further comprises: and transmitting the first information transmitted by the terminal to the third node in response to the second node performing terminal context relocation.

If it is determined that report search is performed in the case where the second node performs terminal context relocation, the first information may be acquired from the terminal and resolved smoothly. In some cases, if the target node to which the first information needs to be sent is a third node other than the first node and the second node, the first node may further forward the first information to the third node.

In some embodiments, the information receiving method further comprises: and in response to the second node not performing terminal context relocation, transmitting first information transmitted by the terminal to the second node, the first information being transmitted by the second node to the third node.

When the second node does not perform the terminal context relocation, if it is determined to perform the report search, the first information may be acquired from the terminal, and the first information may be transmitted to the second node and analyzed by the second node because the first information cannot be analyzed. In some cases, if the target node to which the first information needs to be sent is a third node other than the first node and the second node, the second node may further forward the first information to the third node.

In some embodiments, if terminal context relocation is performed, the first node determines whether to perform report retrieval and sends a report reported by the terminal to the target node (third node)

In some embodiments, if no terminal context relocation is performed, the first node/second node determines whether to perform report retrieval, and further, the first node forwards the report reported by the terminal to the second node, which sends it to the target node (third node).

In some embodiments, receiving a first indication that the terminal is in a disconnected state includes: receiving at least one of the following sent by the terminal in the SDT flow: a first indication; first information, wherein the terminal supports sending to the first node at least one of: a first indication; first information.

In case the terminal has the capability to send the first indication to the network node in the SDT procedure, the terminal may send the first indication and/or the first information to the network node in the SDT procedure, and since the SDT procedure is performed in the non-connected state, it may be achieved that the first indication and/or the first information is sent to the network node in the non-connected state.

In some embodiments, the information receiving method further comprises: receiving capability information sent by the terminal, wherein the capability information is used for indicating that the terminal supports at least one of the following to the first node in the SDT flow: a first indication; first information.

In some embodiments, the information receiving method further comprises: the second node belongs to a predetermined network and sends a first indication to the second node.

In some embodiments, the first node may send a first indication to the second node, the second node determining whether to obtain the first information, e.g., when the second node determines to obtain the first information, the first node may be fed back with an indication indicating that the first node obtained the first information, e.g., when the second node determines not to obtain the first information, the first node may be fed back with an indication indicating that the first node does not obtain the first information. The manner in which the first node determines whether to obtain the first information is similar to the manner in which the first node determines whether to obtain the first information, which is described in the foregoing embodiments, and will not be repeated herein.

Before the first node sends the first indication to the second node, the first node may determine whether the second node belongs to a predetermined network, where the first node sends the first indication to the second node only if the second node belongs to the predetermined network, and where the second node does not belong to the predetermined network, the first node does not have to send the first indication to the second node.

In a third aspect, embodiments of the present disclosure provide an information receiving method. Fig. 5 is a schematic flow chart diagram illustrating an information receiving method according to an embodiment of the present disclosure. The information receiving method shown in the present embodiment may be performed by a second node, and the second node may have a function of implementing the operations in the following embodiments.

As shown in fig. 5, the information receiving method may include the steps of:

in step S501, a second indication sent by the first node is received, wherein the second indication is used by the second node to determine whether to perform terminal context relocation.

In some embodiments, while the terminal is in the non-connected state, the first node may receive the first indication sent by the terminal, but the terminal context (context) may be stored in the second node, and when the first node is not the same node as the second node, the first node does not have the terminal context, so that the information from the terminal cannot be resolved correctly.

Thus, in this embodiment, after receiving the first indication, the first node may send a second indication to the second node according to the first indication, where the second indication may be used by the second node to determine whether to perform terminal context relocation. Wherein the second node performs a terminal context relocation, may comprise sending the terminal context to the first node.

In some embodiments, the second node determines whether to perform the terminal context relocation based on a protocol convention or a policy of the second node.

In some embodiments, the information receiving method further comprises: determining not to execute terminal context repositioning, and receiving first information acquired by a first node from a terminal; the first information is sent to the third node.

If the first node determines to perform report search in the case where the second node does not perform terminal context relocation, the first information may be acquired from the terminal, and since the first information cannot be parsed, the first information may be transmitted to the second node, and the first information may be parsed by the second node. In some cases, if the target node to which the first information needs to be sent is a third node other than the first node and the second node, the second node may further forward the first information to the third node.

Taking the example that the first node includes a receiving gNB and the second node includes a last serving gNB, the terminal may send the first indication to the first node in the SDT procedure.

As shown in fig. 6, the terminal in the non-connected state may perform an SDT procedure and send a first indication to the first node in the SDT procedure, where the SDT procedure may include the terminal sending an rrcreseume message and an SDT message to the first node. For example, the first indication may be carried in the rrcreseume message.

After the first node receives the first indication, if the first node and the second node are not the same node, the first node may determine that terminal context relocation is required, and send a second indication, for example, a search terminal context request, to the second node for the second node to perform terminal context relocation. For example, the search terminal context request may carry a first indication, and may also carry information other than the first indication, for example, an SDT indication, auxiliary information, and the like.

After receiving the second indication, if it is determined that the terminal context relocation is performed, the second node may send a response to the first node to check the terminal context, where the response may include the terminal context.

After receiving the terminal context, the first node may determine to proceed with the SDT procedure. In some embodiments, the first node may also send an Xn-U address indication to the second node.

The first node may send a path switch request to an access mobility management function (Access and Mobility Management Function, AMF), which may feed back a path switch request acknowledgement to the first node.

In some embodiments, the first node may perform uplink non-access stratum transmissions, such as non-access stratum protocol data units (Protocol Data Unit, PDUs).

In some embodiments, the first node may send a report retrieval request to the terminal in a subsequent SDT procedure, where the terminal may send information to the first node, such as by carrying the report in a subsequent SDT message (i.e., a non-initial SDT message), and also carrying the size (size) of the remaining report. The first node may further send information from the terminal to a trace collection entity (Trace Collection Entity, TCE).

The first node may determine a terminating SDT procedure and send a radio resource control release (RRCRelease) message to the terminal, where the RRCRelease may carry a Suspend configuration (Suspend Config). In addition, the first node may send a terminal context release message to the second node.

As shown in fig. 7, the terminal in the non-connected state may perform an SDT procedure and send a first indication to the first node in the SDT procedure, where the SDT procedure may include the terminal sending an rrcreseume message and an SDT message to the first node. For example, the first indication may be carried in an SDT message.

After receiving the second indication, the second node may reserve the terminal context and perform a partial terminal context transfer to the first node if it is determined that the terminal context relocation is not performed (partial UE context transfer).

After receiving the partial terminal context, the first node may send a partial terminal context transfer acknowledgement message to the second node.

The first node may then establish a small data transfer radio link control (Radio Link Control, RLC) entity and the second node may then reserve a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) entity.

In some embodiments, the first node may indicate the RRC transfer to the second node, in which process the first indication, e.g., the SDT message carrying the first indication described above, may be sent to the second node, and may further be sent to the TCE.

In some embodiments, the first node may send a report retrieval request to the terminal in a subsequent SDT procedure, where the terminal may send information to the first node, such as by carrying the report in a subsequent SDT message (i.e., a non-initial SDT message), and also carrying the size (size) of the remaining report. The first node may further send information from the terminal to the second node and may also send to the TCE.

The first node may detect the end of the SDT procedure and then retrieve a terminal context acknowledgement (RETRIEVE UE CONTEXT CONFIRM) to the second node, thereby ending the SDT procedure.

The second node may send a check-out terminal context failure message to the first node, which may carry an RRCRelease message, where the node may send an RRCRelease message to the terminal, and where the RRCRelease may carry a Suspend configuration (Suspend Config).
