First, technical terms related to the embodiments of the present application are introduced to facilitate understanding by those skilled in the art.

(1) Cell handover

A cell Switch (Channel Switch) may refer to a Channel Switch that is required to maintain uninterrupted communication of a terminal device when the terminal device moves from one cell (referring to a network device or a coverage area of the network device) to another cell in a wireless communication system.

In an actual communication network environment, for example, in a communication system such as LTE, NR, etc., where the network coverage of the network device may have some places with poor coverage, the network device may ensure continuity of the voice service of the terminal device by switching to a cell of the same system or a cell of a different system. The voice service may include a call between terminal devices (e.g., a call between mobile phones).

For example, the present invention relates to a Single Radio Voice Call Continuity (SRVCC) technical solution for LTE, so as to ensure the Continuity of the Voice service of the terminal device. In this case, the voice phone may be switched from an LTE + IMS (IP Multimedia system) network based on a Packet Switching (PS) bearer to a 2G or 3G network based on a Circuit Switching (CS) bearer. The general procedure for SRVCC may be: the terminal equipment can report a measurement report to the LTE access network, the LTE access network informs the core network to trigger a switching process, and after the CS resources are prepared, a switching instruction can be sent to the terminal equipment to complete the final switching action.

For example, for NR, since NR and LTE both use IMS technology to implement voice Service, if there is handover between these two systems in cell handover, the handover between these two systems may be implemented without using any IMS Service Continuity (IMS Service Continuity) mechanism, and the terminal device may use a normal handover procedure from NR to LTE.

It should be noted that the present application may be applied to a terminal device having a specific IMS call capability and supporting a voice function based on a cellular network. The terminal device may be a voice center type terminal device or a data center type terminal device, which is not specifically limited in this application.

(2) B2 event

The B2 event is an important event in the above-described cell handover procedure. Ideally, the network device may allow the terminal device to report the signal strengths of the serving cell and the neighbor cells and trigger cell handover with a single measurement. In practical applications, however, an overload situation may be caused due to unnecessary ping-pong handover. To avoid this, a set of predefined measurement reporting mechanisms performed by the terminal device may be utilized. These predefined metric report types may be referred to as "events," for example, events may include a classification into two categories, a1-a6 and B1-B2, with a generic category a events being used intra-system and B events being used inter-system. The type of "event" that the terminal device must report may be specified by a Radio Resource Control (RRC) message sent by the network device. Wherein, the B2 event is one of the above mentioned B events. The B2 event can be understood as: event B2 is triggered when the serving cell of the terminal device is below Threshold1 and the foreign system cell becomes above Threshold 2. Generally, after the network device configures the B2 event, only if the terminal device reports the measurement report for the B2 event, the network device will perform the subsequent procedure, that is, send the handover command to the terminal device.

Please refer to fig. 2, which is a flowchart illustrating a cell measurement method according to an embodiment of the present disclosure. As shown in fig. 2, the cell measurement method may include, but is not limited to, the following steps:

s201, the network device sends configuration information aiming at a target event to the terminal device, wherein the configuration information comprises first measurement configuration information and a reporting condition, and the first measurement configuration information comprises a first threshold. Accordingly, the terminal device receives the configuration information.

Wherein, the target event may refer to a B2 event; the configuration information may include first measurement configuration information and a reporting condition, where the first measurement configuration information may include information required by the terminal device when determining whether the reporting condition is met, for example, the first measurement configuration information may include a first Threshold (Threshold 1); the reporting condition may refer to a condition to be satisfied by the subsequent terminal device reporting the measurement report for the B2 event to the network device.

In one implementation, the network device may send configuration information for a target event to the terminal device through an RRC message, and the terminal device may receive the configuration information for the target event, so that a subsequent terminal device may report a measurement report corresponding to the target event by using the configuration information.

S202, if the first threshold is smaller than the preset threshold, the terminal device replaces the first measurement configuration information with second measurement configuration information, and the first threshold in the second measurement configuration information is the preset threshold.

In one implementation, the preset threshold may be determined based on a dropped call threshold. For example, the preset threshold may be a dropped call threshold. The call drop threshold may be a minimum threshold for maintaining a normal call when the terminal device operates a voice service. In other words, when the signal strength of the serving cell is higher than the preset threshold, the call of the terminal device can be normally performed; when the signal strength of the serving cell is lower than the preset threshold, the probability of call drop or silence occurring in the terminal device during the call process is increased, so that the normal operation of the voice service cannot be maintained.

Optionally, the call drop threshold may be preset, for example, the call drop threshold may be set according to a characteristic of the terminal device, where the characteristic may include a performance of a chip configured by the terminal device, a voice environment in which the terminal device is located, and the like.

Optionally, the call drop threshold may be set based on the performance of a chip configured by the terminal device. It can be understood that, the performances of different terminal devices are different, for example, the chips configured for the terminal devices are different, and the corresponding performances are also different. If the performance of a chip configured for a certain terminal device is better, the performance of the corresponding terminal device is also better, and under the condition that the performance of the terminal device is better, the self anti-interference capability of the terminal device is also stronger, for example, when the terminal device is in a weak field, the probability of call drop or silence occurring in the call process is lower. As can be seen from the above description, the drop call threshold may be negatively related to the performance of the chip, that is, the better the performance of the chip is, the lower the corresponding drop call threshold may be set, and the worse the performance of the chip is, the higher the corresponding drop call threshold may be set. Wherein, weak field may refer to an area with poor communication signal or an area with poor network coverage. As in the actual network environment, the network coverage of LTE and NR may have some places with poor coverage, which may be called weak fields.

Optionally, the call drop threshold may be set based on the voice environment in which the terminal device is located. For example, the drop threshold may be negatively correlated with the voice environment, i.e., the better the voice environment, the lower the corresponding drop threshold may be set, and the worse the voice environment, the higher the corresponding drop threshold may be set. The poor voice environment may refer to a place with poor communication signals such as a mountain and a deep forest, and the good voice environment may refer to a place with good communication signals such as a city. It can be understood that, in a poor voice environment, a communication signal between the terminal device and the network device is poor, and the probability of call drop or silence occurring when the terminal device is in a call process is higher, the call drop threshold of the terminal device can be set to be higher; correspondingly, in a better voice environment, the communication signal between the terminal device and the network device is better, and the probability of call drop or silence occurring when the terminal device is in the process of communication is smaller, so that the call drop threshold of the terminal device can be set to be lower.

In one implementation, if the first threshold is smaller than a preset threshold, the first measurement configuration information may be replaced with the second measurement configuration information. Wherein, the first threshold in the second measurement configuration information is a preset threshold. That is, the first threshold in the first measurement configuration information may be replaced by a preset threshold, and the replaced first measurement configuration information is the second measurement configuration information. Optionally, the terminal may not adjust other information in the configuration information of the target event except the first threshold, and only adjusts the first threshold to the preset threshold. In this way, ping-pong handover of the terminal can be avoided. No adjustment is required such as the hysteresis value (Hys) and the offset value (Ofn) included in the first measurement configuration information. Wherein the setting of information such as hysteresis values and compensation values can be used to avoid ping-pong handovers.

In one implementation, it may be detected whether a service currently operated by the terminal device is a Voice service, where the Voice service may refer to that the terminal device is in a call state, and the Voice service may be, for example, VoLTE (Voice over LTE, a call established through an LTE network), VoNR (Voice over NR, a call established through an NR network), or a Voice service carried on another communication system (e.g., 6G, a future communication system, etc.).

If the detection result is that the currently running service is in the voice service, the step of replacing the first measurement configuration information with the second measurement configuration information if the first threshold is smaller than the preset threshold can be triggered.

If the detection result is that the currently running service is not in the voice service, the current operation can be terminated, that is, the subsequent operation is not executed. And when receiving the configuration information from the network device for the target event and detecting that the currently running service is in the voice service, the step of replacing the first measurement configuration information with the second measurement configuration information if the first threshold is smaller than the preset threshold can be continuously triggered. For example, when the currently running service is a data service (watching a video, browsing news, etc.), the replacement operation and the subsequent operation of the first threshold may not be required, and the processing may be performed according to the original processing flow of the B2 event.

Optionally, the specific implementation manner of detecting whether the currently running service of the terminal device is a voice service may be: under the condition that the terminal equipment is a calling telephone, the terminal equipment can check whether a message of answering the telephone of an opposite terminal is received, if the message of answering the telephone of the opposite terminal is received, the currently running service can be determined to be a voice service, and if the message of answering the telephone of the opposite terminal is not received, the currently running service can be determined not to be the voice service. Under the condition that the terminal equipment is a called telephone, the terminal equipment can check whether a message for answering the telephone is sent or not, if the message for answering the telephone is sent, the currently running service can be determined to be a voice service, and if the message for answering the telephone is not sent, the currently running service can be determined not to be the voice service.

S203, the terminal device carries out cell measurement on the service cell and the adjacent cell to obtain a measurement result.

The serving cell may refer to a cell currently providing a serving signal for the terminal device. The network device serves the serving cell.

The number of the adjacent cells may include one or more; the neighbor cell may be an inter-system neighbor cell. Optionally, the system may also be a neighboring cell of the same system. Optionally, the terminal device may measure one or more neighboring cells in a neighboring cell list, where the neighboring cell list may be configured by the network device, and the neighboring cell list may be a set of cells that the network device sets for the terminal device to perform cell handover smoothly. For example, the neighbor cell list may be recorded in the configuration information of the target event, and after the terminal device receives the configuration information for the target event from the network device, the neighbor cell may be determined from the configuration information.

In one implementation, the terminal device may perform cell measurement on the serving cell and the neighboring cell to obtain a measurement result, where the measurement result may include the signal strength of the serving cell and the signal strength of the neighboring cell. The Signal strength may be characterized by Reference Signal Receiving Power (RSRP) or by other measured values, which is not limited in this embodiment of the present application. For convenience of the following description, the signal strength of the serving cell may be referred to as a first signal strength.

In an implementation manner, the number of the neighboring cells may be one or more, and when the number of the neighboring cells is multiple, the cell measurement may be performed on each neighboring cell to obtain the signal strength of each neighboring cell, that is, the measurement result may include signal strengths corresponding to the multiple neighboring cells, respectively.

And S204, if the report condition is determined to be met according to the measurement result and the second measurement configuration information, the terminal equipment generates a measurement report of the target event.

In one implementation, if it is determined that the reporting condition is satisfied according to the measurement result and the second measurement configuration information, a measurement report for the target event may be generated, so that the measurement report may be further sent to the network device for a subsequent cell handover procedure. If it is determined that the reporting condition is not satisfied according to the measurement report and the second measurement configuration information, the terminal may continue to monitor whether the configuration information for the target time is received from the network device, and if the configuration information for the target event is received by the terminal, step S202 to step S205 may be repeatedly performed.

Optionally, the second measurement configuration information may further include a second threshold. Wherein, satisfying the reporting condition may include: the first signal intensity of the service cell is smaller than the first threshold in the second measurement configuration information, and the signal intensity of the adjacent cell is larger than the second threshold.

For example, the reporting condition can be characterized by the following formula (1):

Mpcell<ThA

Mneighbour>Threshold2 (1)

where, mcpell represents the first signal strength of the serving cell, ThA represents the first Threshold (i.e. the preset Threshold) in the second measurement configuration information, Mneighbour represents the signal strength of the neighboring cell, and Threshold2 represents the second Threshold.

Optionally, the second measurement configuration information may further include a second threshold, a hysteresis value, and a compensation value. The meeting of the reporting condition may include: the sum of the first signal strength and the hysteresis value of the serving cell is smaller than the first threshold in the second measurement configuration information, and the sum of the signal strength and the second value of the neighboring cell is larger than the second threshold, and the second value may be a difference between the compensation value and the hysteresis value.

For example, the reporting condition can be characterized by the following formula (2):

Mpcell+Hys<ThA

Mneighbour+Ofn-Hys>Threshold2 (2)

where Hys denotes a hysteresis value and Ofn denotes a compensation value.

In one implementation, after determining that the reporting condition is satisfied, a measurement report for the target event may be generated. Optionally, the signal strength of the serving cell and the signal strength of the neighboring cell may be recorded in the measurement report.

It is considered that the network device may trigger whether the network device may perform a subsequent handover procedure (e.g., send a handover instruction to the terminal) based on the magnitude of the signal strength of the serving cell in the measurement report. For example, if the signal strength of the serving cell in the measurement report is less than the first threshold, a subsequent handover procedure may be performed. The first threshold here refers to a first threshold in configuration information configured by the network device for the target event, where the first threshold refers to a first threshold in the first measurement configuration information, but not a first threshold in the second measurement configuration information. If the true signal strength (i.e., the first signal strength) of the serving cell is reported to the network device, when the network device determines whether a subsequent handover procedure needs to be performed according to the first signal strength and the first threshold, the network device may stop the handover procedure after determining a magnitude relationship between the first signal strength and the first threshold.

As can be seen from the above description, in the present application, the first threshold in the first measurement configuration information is replaced by a preset threshold, and the preset threshold is greater than the first threshold in the first measurement configuration information, that is, the first threshold in the first measurement configuration information is smaller than the first threshold in the second measurement configuration information; when the above-mentioned judgment meets the reporting condition, it can only be ensured that the first signal strength is smaller than the first threshold (i.e. the preset threshold) in the second measurement configuration information, and it cannot be ensured that the first signal strength is smaller than the first threshold in the first measurement configuration information. When the signal strength of the serving cell is reported to the network device through the measurement report, the signal strength of the serving cell is indicated through the first signal strength, and it cannot be ensured that the value used for indicating the signal strength of the serving cell in the measurement report is smaller than the first threshold in the first measurement configuration information, and further, it cannot be ensured that the network device triggers the handover procedure. Optionally, the first signal strength may be adjusted, so that the adjusted first signal strength may be smaller than the first threshold in the first measurement configuration information, and the adjusted first signal strength may be the signal strength of the serving cell recorded in the measurement report. For convenience of description, the adjusted first signal strength may be referred to as a second signal strength, i.e., the second signal strength of the serving cell may be included in the measurement report. For example, the specific implementation manner of adjusting the first signal strength to obtain the second signal strength is as follows: the second signal strength may be a difference between the first signal strength and a first value, wherein the first value may be a difference between a preset threshold and the first threshold.

For example, the second signal strength may be determined by using the following equation (3):

P＝Mpcell－(ThA－Threshold1) (3)

where P represents the second signal strength.

It should be noted that the signal strength (e.g., the first signal strength, etc.) and the threshold (e.g., the preset threshold, the first threshold, etc.) of the cell referred to in this application may be characterized by using numerical values. For example, for signal strength, the signal strength of a serving cell (first signal strength) may be-80 dBm and the signal strength of a neighbor cell may be-76 dBm. As another example, for a threshold, the preset threshold may be-83 dBm and the first threshold may be-81 dBm.

According to the description of the reporting condition, the method and the device can replace the first threshold in the target event by the preset threshold to realize the early reporting of the measurement report under the condition that the first threshold configured by the network device is smaller than the preset threshold, so that the measurement report can be reported to the network device in time when the terminal device enters a weak field, and the network device can send a switching instruction to the terminal device.

For example, assume that the preset threshold (i.e., the first threshold in the second measurement configuration information) is-83 dBm, the first threshold in the first measurement configuration information is-85 dBm, and the first signal strength of the terminal device is-84 dBm. If the first threshold in the first measurement configuration information is used to judge whether the reporting condition is met, because-84 dBm > -85dBm, it can be determined that the reporting condition is not met, the terminal device cannot send a measurement report to the network device, the network device cannot send a switching instruction to the terminal device, and the first signal strength of the current terminal device is smaller than the preset threshold, then the probability of call drop or silence occurring in the voice service of the terminal device is larger, thereby affecting the continuity of the voice service. And if the first threshold in the second measurement configuration information in the application is used for judging whether the reporting condition is met, because-84 dBm < -83dBm, the reporting condition can be determined to be met, the terminal equipment can send a measurement report to the network equipment, and the network equipment can also send a switching instruction to the terminal equipment in time so as to ensure the continuity of the voice service.

Therefore, the method and the device can actively trigger the network equipment to send the switching instruction in time by actively modifying the reporting threshold of the target event (B2 event) by the terminal equipment, and are favorable for switching the terminal equipment to the adjacent cell with better signal to continue voice service, so that the condition of dropped call or silence when the terminal equipment enters a weak field can be avoided.

S205, the terminal device sends a measurement report to the network device. Accordingly, the network device receives the measurement report.

In one implementation, a terminal device may send a measurement report to a network device to cause the network device to receive the measurement report. After the network device receives the measurement report, it can select a suitable neighbor cell for the terminal to provide a service signal based on the data in the measurement report, and use the suitable neighbor cell as a new serving cell of the terminal, and further send a switching instruction to the terminal device, so that the terminal device can be switched from the current serving cell to the new serving cell.

In this embodiment of the present application, the terminal device may receive configuration information for a target event from the network device, where the configuration information may include first measurement configuration information and a reporting condition, where the first measurement configuration information includes a first threshold, and if the first threshold is smaller than a preset threshold, the first measurement configuration information may be replaced with second measurement configuration information, where the first threshold in the second measurement configuration information is a preset threshold. Further, cell measurement may be performed on the serving cell and the neighboring cell to obtain a measurement result, and if it can be determined that the reporting condition is satisfied according to the measurement result and the second measurement configuration information, a measurement report of the target event may be generated, and the measurement report may be sent to the network device. By implementing the method, when a first Threshold (Threshold1) in a target event configured by the network equipment is lower than a preset Threshold (ThA), Threshold1 can be replaced by ThA, that is, the value of the first Threshold is increased, so that when the voice service of the terminal equipment enters a weak field and a reporting Threshold of a measurement report configured by the network equipment is too low, the measurement report is actively reported in advance, so that the network equipment can be triggered to switch the terminal equipment to a more stable neighboring cell with a better service signal to continue the voice service, thereby ensuring the continuity of the voice service, improving the voice (call) quality of the terminal equipment, and further improving the user call experience.

In order to better understand the cell measurement method provided in the embodiment of the present application, the following further describes with reference to the flow shown in fig. 3. As shown in fig. 3, taking the voice service as a call service for example, a specific implementation process may include the following steps:

s0, the terminal device may identify a preset threshold (ThA) configured by itself, where the preset threshold may be a drop threshold of the terminal device in the call service. Optionally, each terminal device product may set a minimum call threshold corresponding to the product, that is, a call drop threshold.

S1, the terminal device may monitor whether the IMS call is established, that is, whether the currently running service is a call service. For example, for a calling phone, the terminal device may check whether a message for answering the phone by the opposite terminal is received, may determine that an IMS call is established if the message for answering the phone by the opposite terminal is received, and may determine that the IMS call is not established if the message for answering the phone by the opposite terminal is not received. For another example, for a called phone, the terminal device may check whether a message to answer the phone has been sent, and if the message to answer the phone has been sent, it may determine that the IMS call has been established, and if the message to answer the phone has not been sent, it may determine that the IMS call has not been established. In the case that the IMS call is monitored to be established, the following step S2 may be executed; in the case that it is detected that the IMS call is not established, the subsequent steps may be terminated, or the monitoring may be continued until it is detected that the terminal device has established the IMS call, and then the following step S2 may be executed.

S2, in the case that the terminal device monitors that the IMS call is established, the terminal device may monitor whether configuration information for the B2 event sent by the network device is received. If the configuration information of the B2 event transmitted by the network device is received, the following step S3 may be performed; if the configuration information of the B2 event sent by the network device is not received, the subsequent steps may be terminated, or whether the terminal device has established the IMS call and has received the configuration information for the B2 event sent by the network device may be continuously monitored, and if the terminal device has established the IMS call and has received the configuration information for the B2 event sent by the network device is monitored, the following step S3 may be executed.

S3, the terminal device reads the configuration information of the B2 event, checks the configuration about Threshold1 (first Threshold) from the configuration information, and compares Threshold1 with the dropped call Threshold (ThA). If Threshold1 is greater than ThA, execution of subsequent steps may be terminated; if Threshold1 is less than ThA, the following step S4 may be performed.

S4, in case that Threshold1 is smaller than ThA, the terminal device may use ThA instead of Threshold1 to replace Threshold1 in the configuration information with ThA, and store it as a local new B2 event, where Threshold1 in the configuration information of the new B2 event is replaced with ThA, and other information in the configuration information is not changed.

And S5, the terminal equipment judges whether the reporting condition of the new B2 event is met, wherein the reporting condition is contained in the configuration information. If the reporting condition of the new B2 event is satisfied, the following step S6 may be performed. If the reporting condition of the new B2 event is not satisfied, the subsequent steps may be terminated, or the monitoring of the B2 event may be continued to repeat the above steps. Optionally, the reporting condition may include: measured signal strength of serving cell (PCell) plus hysteresis value (Hys), less than ThA, i.e., mcpell + Hys < ThA; meanwhile, the measured signal strength of the inter-system neighbor cell is added with a compensation value (Ofn), and then a hysteresis value (Hys) is subtracted, wherein the hysteresis value is larger than Threshold2 (a second Threshold) configured in the event of B2, namely Mneighbour + Ofn-Hys > Threshold 2.

S6, if the reporting condition is satisfied, the terminal device may report the measurement report of the B2 event, and may set the signal strength (i.e., the second signal strength) of the serving cell reported to the network device in the measurement report as the actual measurement result (i.e., the first signal strength) minus ThA a value greater than Threshold1, that is, the signal strength of the serving cell in the measurement report is P ═ mcpell- (ThA-Threshold 1).

As can be seen from the above description, a call drop threshold (ThA) can be configured inside the terminal device. When Threshold1 (the first Threshold) in the inter-system measurement event (B2 event) configured by the network device is higher than or equal to the call drop Threshold (ThA), the inter-system measurement and reporting procedure can be normally performed. When the Threshold1 in the inter-system measurement event (B2 event) configured by the network device is lower than ThA, in order to ensure continuity of voice service of the terminal device, the terminal device may replace Threshold1 with ThA, and store ThA as new Threshold1, that is, when the actually measured measurement value (first signal strength) of the serving cell is lower than ThA and the measured value (signal strength) of the inter-system neighbor cell is higher than Threshold2 (second Threshold), the terminal device may report a measurement report for the B2 event to the network device, and set the measurement value of the serving cell in the measurement report to a value slightly lower than Threshold 1. Therefore, the network equipment is triggered to send a switching instruction, the terminal equipment is switched to the adjacent cell which is more stable and has better service signals to continue the call service, so that the normal operation of the call service is kept, the stability of the call service is improved, the situations of call drop or silence and the like are reduced, and the call experience of a user is improved.

In an implementation manner, if the cell measurement method of the present application is applied to an actual application scenario, for example, when a weak field enters a VoLTE call or a VoNR call, and a network device configures a B2 event with a lower Threshold1(Threshold1 is lower than a minimum Threshold ThA for a terminal device to maintain a normal call), the network device may be actively triggered to send a handover instruction by modifying a B2 event reporting Threshold through the terminal device, and the terminal device is handed over to an adjacent cell with a better signal to continue a call, so as to avoid a call drop in the call process.

The above embodiments can be used alone or in combination with each other to achieve different technical effects.
