Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and related equipment. Background Art

[0002] The 3GPP (3rd Generation Partnership Project) protocol stipulates that the network can initiate an RRC reconfiguration procedure for a terminal in the radio resource control (RRC) connected state (RRC_CONNECTED). During the RRC reconfiguration procedure, the protocol further stipulates that the reconfiguration with Sync information element for handover is included in the master cell group (MCG) only after AS security is activated, at least one data radio bearer (DRB) and signaling radio bearer 2 (SRB2) are established, and these radio bearers (RBs) are not suspended.

[0003] When the RBs between the terminal and the base station include only signaling radio bearer 0 (SRB0) and signaling radio bearer 1 (SRB1), the connection state of the terminal can be called a single signaling connection state.

[0004] According to the provisions of the above protocol, the terminal will not be able to receive the synchronous reconfiguration information element (Reconfiguration With Sync) used for handover within this time window, and thus cannot initiate handover, which will lead to problems such as low efficiency of non-access stratum (NAS) message transmission, damaged service establishment, and extended service establishment time.

[0005] To address the above issues, one current approach is to set and start a timer when the terminal enters the single signaling connection state. If the terminal does not detect a NAS message before the timer expires, the network device is directly triggered to release the terminal. The duration of this timer is configured through the operation, administration and maintenance (OAM) network element, but this approach has the problem of being difficult to determine the timer duration:

[0006] When the timer duration parameter value is larger, the terminal in the single signaling connection state waits longer to be released, that is, the terminal with a single signaling connection is less likely to be released. In this way, when the signal quality between the terminal and the serving cell is very poor, the terminal's NAS message delivery, service establishment, service establishment delay, etc. will not be guaranteed.

[0007] When the timer duration parameter value is smaller, the terminal in the single signaling connection state waits less time to be released, that is, the terminal with a single signaling connection is more likely to be released. This will cause terminals that need to establish a Protocol Data Unit (PDU) session to repeatedly attempt to access the network, increasing terminal access latency and, in extreme scenarios, causing signaling storms. After the terminal is released, if there is a subsequent NAS message to be transmitted or a service to be established between the network and the terminal, the terminal will need to re-establish the RRC connection, increasing system overhead and service latency. Summary of the Invention

[0008] In view of this, the present application provides a communication method and related equipment, which can reduce the service damage caused by the terminal's inability to switch in time.

[0009] To achieve the above-mentioned object, the first aspect of the present application provides a communication method, comprising:

[0010] A network device receives a measurement report (MR) from a terminal in a single signaling connection state, and determines whether to release a radio resource control (RRC) connection with the terminal in the single signaling connection state according to the measurement report.

[0011] The radio bearers RBs between the terminal in a single signaling connection state and the network device include and only include signaling radio bearer 0 (SRB0) and signaling radio bearer 1 (SRB1).

[0012] Through this method, the terminal in the single signaling connection state is released at the appropriate time, which can not only enable the terminal that can no longer receive the service of the current serving cell to be released in time, reducing the damage to the business caused by the failure to switch in time, but also ensure that the terminal that can normally receive the service of the current serving cell is not released prematurely, reducing system overhead and improving access delay.

[0013] According to the first aspect, in a first possible implementation manner of the communication method, the network device may further send a measurement configuration to the terminal, where the measurement configuration includes: a measurement object and a reporting condition.

[0014] The network device can send a measurement configuration to the terminal via RRC signaling. The measurement configuration includes the measurement objects and reporting conditions configured by the network device for the terminal. On the one hand, the measurement objects are used to indicate the measurements to be performed by the terminal, and on the other hand, the reporting conditions are used to indicate the mechanism by which the terminal reports the measurement results.

[0015] According to the first possible implementation manner of the first aspect, in a second possible implementation manner of the communication method, the measurement object includes at least one of the following:

[0016] The serving cell to which the terminal is currently connected, and at least one neighboring cell of the serving cell to which the terminal is currently connected.

[0017] The network equipment sets the measurement object of the terminal according to the measurement needs. After the terminal receives the measurement object, it can perform measurement on the measurement object. It can measure the service cell to which the terminal is currently connected, as well as multiple adjacent cells of the current service cell, to meet the need to release the wireless resource control connection and then reconnect in subsequent steps.

[0018] According to the first possible implementation manner of the first aspect, in a third possible implementation manner of the communication method, the reporting condition includes at least one of the following: a measurement event, a reporting period.

[0019] After obtaining measurement results, if the terminal meets the reporting requirements, it sends them to the network device. There are two ways to report measurement results to the network device: periodic reporting and event-triggered reporting. Periodic reporting involves configuring a reporting period for the terminal. Upon reaching that period, the terminal triggers a report. Event-triggered reporting involves configuring a measurement event for the terminal. If the terminal's measurement results meet the requirements of the measurement event, the terminal triggers a report. The terminal can report measurement results using a measurement report (MR).

[0020] According to the third possible implementation manner of the first aspect, in a fourth possible implementation manner of the communication method, the measurement event includes at least one of the following:

[0021] A2 event: the serving cell signal quality is lower than the absolute threshold;

[0022] A3 event: The signal quality of the neighboring cell is one offset value higher than that of the serving cell;

[0023] A4 event: the signal quality of the adjacent cell is higher than the absolute threshold;

[0024] A5 event: The serving cell signal quality is lower than the first absolute threshold, and the neighboring cell signal quality is higher than the second absolute threshold;

[0025] B1 event: the signal quality of the adjacent cell is higher than the absolute threshold;

[0026] Event B2: The serving cell signal quality is lower than the first absolute threshold, and the neighboring cell signal quality is higher than the second absolute threshold.

[0027] The signal quality of the serving cell or the adjacent cell may refer to the reference signal measurement value of the currently connected serving cell or the adjacent cell. In the present application, the measurement value of the reference signal includes the reference signal received power (RSRP), the reference signal received quality (RSRQ), the signal to interference plus noise ratio (SINR), or the received signal strength indicator (RSSI). In the present application, the reference signal of the serving cell or the adjacent cell may include a synchronization signal and a physical broadcast channel block (SSB) or a channel state information reference signal (CSI-RS). In the present application, the reference signal of the terminal may include a channel sounding reference signal (SRS).

[0028] There are two types of measurement events: Intra-system measurement events (including intra-frequency and inter-frequency): A1 event: the signal quality of the serving cell is higher than the absolute threshold; A2 event: the signal quality of the serving cell is lower than the absolute threshold; A3 event: the signal quality of the adjacent cell is one bias value higher than the serving cell; A4 event: the signal quality of the adjacent cell is higher than the absolute threshold; A5 event: the signal quality of the serving cell is lower than the first absolute threshold, and the signal quality of the adjacent cell is higher than the second absolute threshold; Inter-system measurement events: B1 event: the signal quality of the adjacent cell is higher than the absolute threshold; B2 event: the signal quality of the serving cell is lower than the first absolute threshold, and the signal quality of the adjacent cell is higher than the second absolute threshold. Network equipment can select the above measurement events for configuration according to measurement requirements, wherein the A2 event to the B2 event in the measurement event can be configured as the method for triggering reporting conditions.

[0029] According to the fourth possible implementation manner of the first aspect, in a fifth possible implementation manner of the communication method, the measurement report includes at least one measurement event.

[0030] When the reporting type of the measurement result is event-triggered reporting, the measurement report reported at this time includes the measurement event satisfied by the terminal's measurement result. The network device can determine to release the radio resource control connection with the terminal based on the measurement report.

[0031] According to the fourth possible implementation manner of the first aspect, in a sixth possible implementation manner of the communication method, the measurement report includes a reference signal measurement value of at least one serving cell or a neighboring cell.

[0032] When the reporting type of the measurement result is periodically triggered reporting, the measurement report reported at this time includes the terminal's measurement results for at least one currently connected serving cell or neighboring cell. The network device can determine whether to release the radio resource control connection with the terminal based on the measurement report. For example, if the network device determines that the reference signal measurement value of the serving cell included in the measurement report is lower than an absolute threshold, or the reference signal measurement value of the neighboring cell is higher than an absolute threshold, or the reference signal measurement value of the neighboring cell is higher than the reference signal measurement value of the current serving cell by an offset value, it determines to release the radio resource control connection with the terminal.

[0033] According to the first aspect, in a seventh possible implementation manner of the communication method, before executing the release, the step further includes:

[0034] The connection status of the terminal is detected, and when it is determined that the terminal is in a single signaling connection, the release is executed.

[0035] Before the network device determines to release the wireless resource control connection with the terminal based on the measurement report, it re-detects the connection status of the terminal. When it is determined that the terminal is in a single signaling connection state, it executes the release to avoid the problem of erroneous release of a terminal in a non-single signaling connection state, which may cause loss of service data.

[0036] According to the first aspect, in an eighth possible implementation manner of the communication method, the method further includes:

[0037] After the release is completed, the terminal sends a request for establishing a connection to a neighboring cell having a better signal quality than the serving cell connected before the release.

[0038] For example, the network device may include an identifier of a neighboring cell with better signal quality than the serving cell in a release message sent to the terminal. After the release is completed, the terminal initiates a connection request to the neighboring cell with better signal quality, thereby reconnecting to the serving cell.

[0039] To achieve the above-mentioned object, the second aspect of the present application provides a communication method, comprising:

[0040] A network device receives a reference signal sent by a terminal in a single signaling connection state, determines the channel quality between the terminal in the single signaling connection state and the network device based on a measured value of the reference signal, and determines whether to release the radio resource control (RRC) connection with the terminal based on the channel quality.

[0041] The radio bearers RBs between the terminal in a single signaling connection state and the network device include and only include signaling radio bearer 0 (SRB0) and signaling radio bearer 1 (SRB1).

[0042] In the present application, the reference signal of the terminal may include a channel sounding reference signal (SRS). The network device evaluates the channel quality through the received channel sounding reference signal and determines whether to release the radio resource control connection with the terminal in a single signaling connection state based on the channel quality.

[0043] Through this method, terminals in a single signaling connection state are released at an appropriate time, which can ensure that terminals that cannot continue to receive services from the current serving cell are released in a timely manner, reducing business damage caused by failure to switch in time, and can also ensure that terminals that can normally receive services from the current serving cell are not released prematurely, reducing system overhead and improving access delay.

[0044] To achieve the above-mentioned object, the third aspect of the present application provides a communication device, including:

[0045] bus;

[0046] a communication interface connected to the bus;

[0047] at least one processor connected to the bus; and

[0048] At least one memory is connected to the bus and stores program instructions. When the program instructions are executed by the at least one processor, the at least one processor executes any one of the communication methods.

[0049] To achieve the above-mentioned purpose, the fourth aspect of the present application provides a computer-readable storage medium having program instructions stored thereon, which, when executed by a computer, enables the computer to execute any one of the methods described in the communication method.

[0050] To achieve the above-mentioned purpose, the fifth aspect of the present application provides a computer program product, which includes program instructions. When the program instructions are executed by a computer, the computer executes any one of the communication methods.

[0051] To achieve the above-mentioned purpose, the sixth aspect of the present application provides a communication device, which is used to execute any one of the methods described in the communication method.

[0052] These and other aspects of the present application will become more apparent from the following description of the embodiment(s). BRIEF DESCRIPTION OF THE DRAWINGS

[0077] SRB is a special radio bearer that is only used to transmit RRC and NAS messages. The transmission channel of SRBs is defined in protocol 36.331:

[0092] There are two types of measurement events:

[0093] Measurement events in the same system (including same frequency and different frequency):

[0094] A1 event: the serving cell signal quality is higher than the absolute threshold;

[0095] A2 event: the serving cell signal quality is lower than the absolute threshold;

[0101] Event B2: The serving cell signal quality is lower than the first absolute threshold, and the neighboring cell signal quality is higher than the second absolute threshold.

[0102] In the case that the radio bearers (RBs) between the terminal and the base station include and only include SRB0 and SRB1, the connection state of the terminal can be referred to as a single signaling connection state.

[0103] Technology 1: Based on the problem that the terminal with a single signaling connection cannot directly initiate a handover, the existing technology sets and starts a timer. If the terminal does not detect a NAS message before the timer expires, it directly triggers the network side to release the terminal.

[0104] Disadvantages of technology 1:

[0105] When the timer duration parameter value is larger, the terminal in the single signaling connection state waits longer to be released, that is, the terminal with a single signaling connection is less likely to be released. In this way, when the signal quality between the terminal and the serving cell is very poor, the terminal's NAS message delivery, service establishment, service establishment delay, etc. will not be guaranteed.

[0106] When the timer duration parameter value is set to a smaller value, the time a terminal in a single signaling connection state waits for release is shorter, that is, a terminal with a single signaling connection is more likely to be released. This causes terminals that need to establish a PDU session to repeatedly attempt to access the network, increasing terminal access latency and, in extreme scenarios, causing signaling storms. After the terminal is released, if there are subsequent NAS messages to be transmitted between the network and the terminal or services need to be established, the terminal needs to re-establish the radio resource control connection, increasing system overhead and service latency.

[0107] To address the shortcomings of the aforementioned technologies, embodiments of the present application provide a communication method and related equipment. By designing a signal quality detection mechanism for terminals with a single signaling connection, terminals with a single signaling connection are released at an appropriate time, thereby reducing service losses caused by the inability of terminals to switch in a timely manner. This application is described in detail below.

[0108] Example 1

[0109] like Figure 1 An embodiment of the present application provides a communication method, the method comprising:

[0110] S101: A network device receives a measurement report sent by a terminal.

[0111] Exemplarily, the terminal may be in a single signaling connection state.

[0112] The RBs between a terminal in a single signaling connection state and the network device may include and only include signaling SRB0 and SRB1. Alternatively, a terminal in a single signaling connection state refers to a terminal that has not yet established a PDU session. Alternatively, the terminal is in a single signaling connection state from the time the terminal accesses the cell until the core network instructs the terminal to establish a PDU session.

[0113] Optionally, before the terminal sends the measurement report to the network device, the network device may send a measurement configuration to the terminal.

[0114] Specifically, the measurement configuration includes a measurement object and a reporting condition, wherein the measurement object is used to indicate the measurement object to be measured by the terminal, and the reporting condition is used to indicate the mechanism by which the terminal reports the measurement result.

[0115] In an embodiment of the present application, a measurement object for a terminal may be set based on measurement needs, where the measurement object may be set to include at least: a serving cell to which the terminal is currently connected, or at least one neighboring cell of the current serving cell. After receiving the measurement object, the terminal may measure the serving cell to which the terminal is currently connected, or may measure multiple neighboring cells of the current serving cell, based on the set measurement object, to meet the requirement of releasing the radio resource control connection and then reconnecting in subsequent steps.

[0116] In an embodiment of the present application, the reporting conditions of the terminal can be set according to measurement needs, wherein the reporting conditions can be set to at least include: a measurement event, or a reporting period. The terminal performs corresponding measurements according to the measurement object set above, and after obtaining the measurement results, it can implement event-triggered reporting or periodic reporting according to the set reporting conditions. Among them, the periodic reporting method refers to the network device configuring a reporting period for the terminal, and when the reporting period is reached, the terminal can trigger a report; the event-triggered reporting method refers to the network device configuring a measurement event for the terminal, and if the terminal's measurement result meets the requirements of the measurement event, the terminal can trigger a report.

[0117] In some embodiments of the present application, the measurement event may include at least one of the following:

[0118] A2 event: the serving cell signal quality is lower than the absolute threshold;

[0119] A3 event: The signal quality of the neighboring cell is one offset value higher than that of the serving cell;

[0120] A4 event: the signal quality of the adjacent cell is higher than the absolute threshold;

[0121] A5 event: The serving cell signal quality is lower than the first absolute threshold, and the neighboring cell signal quality is higher than the second absolute threshold;

[0122] B1 event: the signal quality of the adjacent cell is higher than the absolute threshold;

[0123] Event B2: The serving cell signal quality is lower than the first absolute threshold, and the neighboring cell signal quality is higher than the second absolute threshold.

[0124] Among them, the above-mentioned serving cell or adjacent cell signal quality may refer to the reference signal measurement value of the serving cell or the adjacent cell. In the present application, the measurement value of the reference signal includes the reference signal received power (reference signal received power, RSRP), the reference signal received quality (reference signal received quality, RSRQ), the signal to interference plus noise ratio (signal to interference plus noise ratio, SINR), or the received signal strength indicator (received signal strength indicator, RSSI). In the present application, the reference signal of the serving cell or the adjacent cell may include a synchronization signal and a physical broadcast channel block (synchronization signaland physical broadcast channel block, SSB) or a channel state information reference signal (channel state information reference signal, CSI-RS). In the present application, the reference signal of the terminal may include a channel sounding reference signal (SRS).

[0125] The terminal completes the measurement of the measurement object according to the set measurement object, obtains the measurement result, and when the measurement result meets the above-set reporting conditions, the terminal can report the measurement result to the network device through a measurement report.

[0126] S102: The network device determines whether to release the communication connection with the terminal according to the measurement report.

[0127] The communication connection may be an RRC connection.

[0128] In an embodiment of the present application, the measurement report sent by the terminal and received by the network device includes an event-triggered report or a periodic report. Specifically, when the reporting type of the measurement report is event-triggered reporting, the measurement report reported at this time includes at least one of the above-mentioned set measurement events, and the network device can determine to release the radio resource control connection between the terminal and the measurement report. When the reporting type of the measurement report is periodically triggered reporting, the measurement report reported at this time includes the terminal's measurement results of at least one currently connected serving cell or neighboring cell. The network device can determine whether to release the radio resource control connection between the terminal and the measurement report based on the measurement report. For example, if the network device determines that the reference signal measurement value of the serving cell included in the measurement report is lower than an absolute threshold, or the reference signal measurement value of the neighboring cell is higher than an absolute threshold, or the reference signal measurement value of the neighboring cell is higher than the reference signal measurement value of the current serving cell by an offset value, then it is determined to release the radio resource control connection between the terminal.

[0129] Optionally, before determining to execute the above-mentioned release based on the measurement report, the network device may further detect the connection status of the terminal and execute the above-mentioned release when it determines that the terminal is in a single signaling connection. This avoids the problem of erroneous release of a terminal in a non-single signaling connection state, which may cause loss of service data.

[0130] Exemplarily, after the network device completes the above-mentioned release, it can also enable the terminal to send a request to establish a connection to a neighboring cell whose signal quality is better than the service cell connected before the release. Specifically, when the measurement report sent by the terminal contains the signal quality of the service cell of the currently connected service cell and the signal quality of at least one neighboring cell, assuming that the signal quality of the neighboring cell is better than the service cell to which the terminal is currently connected, the network device determines to release the radio resource control connection between the terminal and the terminal based on the measurement report. In addition, the release message sent by the network device to the terminal may also carry the identifier of the neighboring cell whose signal quality is better than the current service cell. Based on the identifier of the neighboring cell, the terminal can initiate a request to establish a connection to the neighboring cell, thereby achieving reconnection of the service cell.

[0131] Example 2

[0132] like Figure 2 FIG. 1 is a flow chart of another communication method provided in an embodiment of the present application, the method comprising:

[0133] S201: A network device receives a reference signal sent by a terminal, and determines a channel quality between the terminal and the network device based on a measurement value of the reference signal.

[0134] Exemplarily, the terminal may be in a single signaling connection state. In an embodiment of the present application, the reference signal of the terminal may include a sounding reference signal (SRS). The network device configures SRS configuration information for the terminal, and sends downlink control signaling (DCI) to the terminal through a downlink physical layer control channel (PDCCH), wherein the SRS configuration information may include a form of reporting SRS configured for the terminal, which may specifically include periodic reporting signaling or triggered reporting signaling. The terminal performs periodic reporting or triggered reporting of the SRS according to the SRS configuration information carried in the received downlink control signaling. The network device evaluates the channel quality between the terminal in a single signaling connection state and the network device based on the received SRS.

[0135] S202: The network device determines whether to release the radio resource control connection with the terminal according to the channel quality.

[0136] In an embodiment of the present application, the network device determines whether to release the wireless resource control connection with the terminal in the single signaling connection state based on the channel quality evaluated above. For example, when the channel quality is lower than a set absolute threshold, it can be determined that the terminal in the single signaling connection state can no longer continue to enjoy the communication service of the current network device or service cell, and then determines to release the wireless resource control connection with the terminal in the single signaling connection state, thereby reducing the service damage caused by the terminal's inability to switch in time.

[0137] Example 3

[0138] like Figure 3 As shown, the present application also provides an embodiment, which specifically introduces the signaling interaction process between the terminal, the network device and the AMF in the present application, which includes:

[0139] S301: The terminal sends an RRC configuration request signaling (RRC Setup Request) to the network device to request to establish an RRC connection;

[0140] S302: The network device receives the RRC configuration request signaling and, if the terminal is allowed, sends a downlink control signaling to the terminal, where the downlink control signaling includes RRC configuration information (RRC Setup (SRB1)).

[0141] S303: The terminal completes the RRC connection with the network device according to the RRC configuration information (RRC Setup (SRB1)) included in the received downlink control signaling, and sends an RRC connection completion signaling (RRC Setup Complete) to the network device;

[0142] After the RRC connection is completed, the terminal enters the RRC connected mode and then executes:

[0143] S304: The network device sends an Initial UE Message to the Access and Mobility Management Function (AMF) to request the establishment of a context for the terminal.

[0144] S305: The AMF receives the context establishment request and sends a control signaling (Initial Context Setup Request) containing the initial context information to the network device;

[0145] S306: The network device establishes a context for the terminal based on the received initial context information and sends an Initial Context Setup Response signaling to the AMF.

[0146] At this point, the network device completes the RRC connection and context establishment with the terminal, but does not establish a PDU session bearer. The terminal is in a single signaling connection state and then executes:

[0147] S307: The network device sends configuration information (RRC Connection Reconfiguration) to the terminal;

[0148] In the embodiment of the present application, the configuration information configured by the network device for the terminal may include two implementation methods, specifically:

[0149] In a first implementation manner, the configuration information includes at least a measurement object or a reporting condition that the terminal needs to perform, wherein the measurement object is used to indicate the measurement object to be measured by the terminal, and the reporting condition is used to indicate the mechanism by which the terminal reports the measurement result.

[0150] In an embodiment of the present application, the measurement object may be set to include at least: the serving cell to which the terminal is currently connected, or at least one neighboring cell of the current serving cell. After receiving the measurement object, the terminal may measure the serving cell to which the terminal is currently connected, or may measure multiple neighboring cells of the current serving cell, based on the set measurement object, and send the measurement results to the network device to meet the requirement of reconnecting after releasing the RRC connection in subsequent steps.

[0151] In an embodiment of the present application, the reporting condition can be set to at least include: a measurement event or a reporting period. The terminal performs corresponding measurements according to the measurement object set above, and after obtaining the measurement results, it can implement event-triggered reporting or periodic reporting according to the set reporting conditions. Among them, the periodic reporting method means that the network device configures a reporting period for the terminal, and when the reporting period is reached, the terminal can trigger a report; the event-triggered reporting method means that the network device configures a measurement event for the terminal, and if the terminal's measurement result meets the requirements of the measurement event, the terminal can trigger a report.

[0152] In this embodiment, the measurement event may be set to include one or more of the following:

[0153] A2 event: the serving cell signal quality is lower than the absolute threshold;

[0154] A3 event: The signal quality of the neighboring cell is one offset value higher than that of the serving cell;

[0155] A4 event: the signal quality of the adjacent cell is higher than the absolute threshold;

[0156] A5 event: The serving cell signal quality is lower than the first absolute threshold, and the neighboring cell signal quality is higher than the second absolute threshold;

[0157] B1 event: the signal quality of the adjacent cell is higher than the absolute threshold;

[0158] Event B2: The serving cell signal quality is lower than the first absolute threshold, and the neighboring cell signal quality is higher than the second absolute threshold.

[0159] The above-mentioned serving cell or neighboring cell signal quality may refer to a reference signal measurement value of the serving cell or the neighboring cell. In this embodiment, the reference signal measurement value includes a reference signal received power (RSRP), a reference signal received quality (RSRQ), a signal to interference plus noise ratio (SINR), or a received signal strength indicator (RSSI). In this embodiment, the reference signal of the serving cell or the neighboring cell may include a synchronization signal and a physical broadcast channel block (SSB) or a channel state information reference signal (CSI-RS).

[0160] In the second implementation method, the configuration information can be set to include the network device configuring SRS configuration information for the terminal, wherein the SRS configuration information may include the form of SRS reporting configured for the terminal, which may specifically include periodic reporting or triggered reporting. The terminal performs periodic reporting or triggered reporting of SRS according to the SRS configuration information, and the network device evaluates the channel quality between the terminal in a single signaling connection state and the network device based on the received SRS.

[0161] S308: The terminal sends a configuration completion signaling (RRC Connection Reconfiguration Complete) to the network device, and performs corresponding measurements or transmissions according to the above configuration information;

[0162] S309: The terminal sends a measurement report to the network device;

[0163] In the embodiment of the present application, according to the two implementation methods of the configuration information in step S307, the terminal also includes two corresponding measurement execution methods and measurement report sending methods. Specifically,

[0164] When the above-mentioned configuration information includes the measurement object or reporting condition in the first implementation method, the terminal performs measurement on the measurement object according to the configuration information, and sends the measurement result to the network device in the form of a measurement report, wherein the network device can judge the channel quality between the terminal and the current serving cell or the adjacent cell based on the received measurement report.

[0165] When the above configuration information includes the SRS configuration information in the second implementation mode, the terminal performs periodic reporting or triggered reporting of SRS according to the SRS configuration information, and the network device needs to further detect the received SRS to determine the channel quality between the terminal and the currently connected service cell.

[0166] S310: The network device releases the RRC connection with the terminal according to the received measurement report (RRC Release);

[0167] In the embodiment of the present application, the network device determines whether to release the RRC connection with the terminal according to the received measurement report;

[0168] Corresponding to the first implementation of step S307, when the reporting type of the measurement report is event-triggered reporting, the measurement report reported at this time contains at least one of the above-mentioned set measurement events, and the network device can determine to release the RRC connection between the terminal and the measurement report; when the reporting type of the measurement report is periodic triggered reporting, the measurement report reported at this time contains the terminal's measurement results of at least one currently connected serving cell or neighboring cell. The network device can determine whether to release the radio resource control connection between the terminal and the measurement report based on the measurement report. For example, if the network device determines that the reference signal measurement value of the serving cell included in the measurement report is lower than an absolute threshold, or the reference signal measurement value of the neighboring cell is higher than an absolute threshold, or the reference signal measurement value of the neighboring cell is higher than the reference signal measurement value of the current serving cell by an offset value, it determines to release the RRC connection between the terminal.

[0169] Corresponding to the second implementation method of step S307, when the measurement report sent by the terminal to the network device only contains SRS, the network device needs to evaluate the channel quality between the terminal in the single signaling connection state and the network device based on the SRS, and determine whether to release the RRC connection with the terminal in the single signaling connection state based on the evaluated channel quality. For example, when the channel quality is lower than a set absolute threshold, it can be determined that the terminal in the single signaling connection state can no longer continue to enjoy the communication service of the current network device or service cell, and then it is determined to release the RRC connection with the terminal in the single signaling connection state.

[0171] like Figure 4 FIG. 4 is an architecture diagram of a network device provided in an embodiment of the present application. The network device 400 includes:

[0172] The configuration unit 401 is configured to configure a measurement configuration, where the measurement configuration includes: a measurement object and a reporting condition;

[0173] In an embodiment of the present application, the measurement object is used to indicate the measurement object to be measured by the terminal, and the reporting condition is used to indicate the mechanism by which the terminal reports the measurement result. The measurement object can be set to include at least: the serving cell to which the terminal is currently connected, or at least one neighboring cell of the current serving cell. After receiving the measurement object, the terminal can measure the serving cell to which the terminal is currently connected, or multiple neighboring cells of the current serving cell, according to the set measurement object, to meet the requirement of releasing the radio resource control connection and then reconnecting in subsequent steps. The reporting condition can be set to include at least: a measurement event or a reporting period. The terminal performs the corresponding measurement according to the above-set measurement object. After obtaining the measurement result, it can implement event-triggered reporting or periodic reporting according to the set reporting condition. The periodic reporting method refers to the configuration unit 401 configuring a reporting period for the terminal. When the reporting period is reached, the terminal can trigger a report; the event-triggered reporting method refers to the configuration unit 401 configuring a measurement event for the terminal. If the terminal's measurement result meets the requirements of the measurement event, the terminal can trigger a report.

[0174] In some embodiments of the present application, the measurement event may include at least one of the following:

[0175] Measurement events in the same system (including same frequency and different frequency):

[0176] A2 event: the serving cell signal quality is lower than the absolute threshold;

[0177] A3 event: The signal quality of the neighboring cell is one offset value higher than that of the serving cell;

[0178] A4 event: the signal quality of the adjacent cell is higher than the absolute threshold;

[0179] A5 event: The serving cell signal quality is lower than the first absolute threshold, and the neighboring cell signal quality is higher than the second absolute threshold;

[0180] Heterosystem measurement events:

[0181] B1 event: the signal quality of the adjacent cell is higher than the absolute threshold;

[0182] Event B2: The serving cell signal quality is lower than the first absolute threshold, and the neighboring cell signal quality is higher than the second absolute threshold.

[0183] Among them, the above-mentioned serving cell or adjacent cell signal quality may refer to the reference signal measurement value of the serving cell or the adjacent cell. In the present application, the measurement value of the reference signal includes the reference signal received power (reference signal received power, RSRP), the reference signal received quality (reference signal received quality, RSRQ), the signal to interference plus noise ratio (signal to interference plus noise ratio, SINR), or the received signal strength indicator (received signal strength indicator, RSSI). In the present application, the reference signal of the serving cell or the adjacent cell may include a synchronization signal and a physical broadcast channel block (synchronization signaland physical broadcast channel block, SSB) or a channel state information reference signal (channel state information reference signal, CSI-RS). In the present application, the reference signal of the terminal may include a channel sounding reference signal (SRS).

[0184] The communication unit 402 is configured to send the measurement configuration to the terminal and receive a measurement report sent by the terminal;

[0185] In an embodiment of the present application, the communication unit 402 receives a measurement report sent by the terminal, which includes an event-triggered report or a periodic report. Specifically, when the reporting type of the measurement report is an event-triggered report, the measurement report reported at this time includes at least one of the above-mentioned set measurement events; when the reporting type of the measurement report is a periodic triggered report, the measurement report reported at this time includes the terminal's measurement results for at least one currently connected service cell or adjacent cell.

[0186] The releasing unit 403 is configured to determine whether to release the radio resource control connection with the terminal according to the measurement report.

[0187] In an embodiment of the present application, when the measurement report includes at least one of the above-mentioned set measurement events, the releasing unit 403 may release the radio resource control connection with the terminal. Alternatively, when the measurement report includes the reference signal measurement value of the terminal for at least one currently connected serving cell or neighboring cell, assuming that the reference signal measurement value of the serving cell included in the measurement report is lower than an absolute threshold, or the reference signal measurement value of the neighboring cell is higher than an absolute threshold, or the reference signal measurement value of the neighboring cell is higher than the reference signal measurement value of the current serving cell by an offset value, it is determined to release the radio resource control connection with the terminal.

[0188] In some embodiments of the present application, before executing the above-mentioned release, the connection status of the terminal may be detected, and when it is determined that the terminal is in a single signaling connection, the release is executed.

[0189] In some embodiments of the present application, after the above-mentioned release is completed, the terminal may also send a request to establish a connection to a neighboring cell whose signal quality is better than the service cell connected before the release. Specifically, when the measurement report sent by the terminal contains the signal quality of the service cell of the currently connected service cell and the signal quality of at least one neighboring cell, assuming that the signal quality of the neighboring cell is better than the service cell to which the terminal is currently connected, the network device determines to release the radio resource control connection between the terminal and the terminal based on the measurement report, and the release message sent by the network device to the terminal may also carry an identifier of the neighboring cell whose signal quality is better than the current service cell. Based on the identifier of the neighboring cell, the terminal can initiate a request to establish a connection to the neighboring cell, thereby achieving reconnection of the service cell.

[0197] The releasing unit 504 is configured to determine whether to release the radio resource control connection with the terminal according to the channel quality.

[0198] In an embodiment of the present application, the release unit 504 determines whether to release the wireless resource control connection between the terminal in the single signaling connection state and the network device based on the result of the channel quality evaluated above. For example, when the channel quality is lower than a set absolute threshold, it can be determined that the terminal in the single signaling connection state can no longer continue to enjoy the communication service of the current network device or service cell, and then it is determined to release the wireless resource control connection with the terminal in the single signaling connection state, thereby reducing the service damage caused by the terminal's inability to switch in time.
