Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present application, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present application, it is noted that, unless explicitly stated or limited otherwise, "including" and "having" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the related art, when a terminal initiating a voice call moves to a network-camping area, a serving cell signal covers a weaker area, the terminal measures the communication quality of a current serving cell based on a measurement configuration of an a2 measurement event issued by a base station corresponding to the serving cell when the terminal camps on the network, and reports the measured communication quality to the base station when the signal quality of the serving cell is lower than a certain threshold (a threshold corresponding to an a2 measurement event). Then the base station will issue the cell measurement configuration for the service cell and the inter-system neighboring cell in the B2 measurement event to the terminal, where the cell measurement configuration includes the decision threshold parameter of the service cell and the decision threshold parameter of the inter-system neighboring cell, and when the measured signal quality of both the service cell and the inter-system neighboring cell meets the decision threshold parameter, the terminal will trigger the base station to switch the currently camped service cell to the inter-system neighboring cell, so as to ensure that the user voice service is not interrupted.

In the process of cell measurement of a serving cell and an inter-system neighbor cell, a decision threshold parameter (e.g., a first trigger threshold corresponding to the serving cell and a second trigger threshold corresponding to the inter-system neighbor cell) issued by a base station side of the serving cell is usually determined by a communication operator when the base station is deployed, and there may be a case where the decision threshold parameter is set unreasonably, when the signal quality of the serving cell satisfies the corresponding decision threshold parameter, and the signal quality of the inter-system neighbor cell does not satisfy the corresponding decision threshold parameter, and at this time, the network environment of the current serving cell is no longer suitable for a call (e.g., the network signal quality corresponding to the current serving cell is further deteriorated), and the network signal quality corresponding to the inter-system neighbor cell is better than that of the serving cell (i.e., the inter-system neighbor cell can satisfy the service transmission requirement of a terminal, such as voice call data), the current resident network cell may not be switched from the serving cell to the inter-system neighbor cell in time, and conditions such as off-line call drop, call delay and the like occur, so that the call quality of the voice call is poor.

The present application will be described in detail with reference to specific examples.

The network cell switching method provided by the present application can be implemented based on the architecture of the network cell switching system shown in fig. 1.

In one embodiment, as shown in fig. 2, a network cell handover method is proposed, which may be implemented by means of a computer program, and which may be run on a network cell handover device based on the von neumann architecture. The computer program may be integrated into the application or may run as a separate tool-like application.

Specifically, the network cell switching method includes:

step S101: and receiving cell measurement configuration sent by a base station corresponding to a service cell in a voice call state, wherein the cell measurement configuration comprises a first trigger threshold corresponding to the service cell and a second trigger threshold of an inter-system neighboring cell.

The serving cell is a current network-residing cell that currently provides service data transmission service for the terminal, and is also called an area where the terminal can currently obtain network service (such as LTE network service), and is a cell divided from the whole communication serving cell (such as LTE communication serving cell), and a base station for communication is arranged in the cell, and is responsible for establishing wireless connection with the terminal in the cell, and supports that the terminal of a communication system (such as LTE communication system) corresponding to the communication service can communicate in any cell in the communication serving cell, for example, the serving cell is used for bearing service data of voice call.

The base Station is a base Station under a communication system (communication system provides Network service) corresponding to a serving cell, and the base Station includes, but is not limited to, a Base Transceiver Station (BTS) in a global system for Mobile communications (GSM) system or a Code Division Multiple Access (CDMA) system, may also be a base Station (NodeB) in a Wideband Code Division Multiple Access (WCDMA) system, may also be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or may be a wireless controller in a Cloud Radio Access Network (CRAN). And so on.

In an actual application environment, when the overall coverage of a cell is better, a terminal may be simultaneously covered by multiple cells (e.g., 2-3 cells) in a mobile or stationary process, where each cell may be a cell in a same system (also referred to as a same system) as a current serving cell of the terminal, and the same system may be understood as two cells belonging to the same communication system (e.g., an LTE communication system and the same GSM communication system); or may be a cell under a heterogeneous system (also referred to as a heterogeneous system) with the current serving cell of the terminal, where the heterogeneous system may be understood as two cells belonging to different communication systems (e.g., one cell belongs to an LTE communication system and the other cell belongs to a GSM communication system); the cell is a basic network element in a mobile wireless network, belongs to a logic unit under a physical entity base station, and has the following main basic attributes: the method comprises the following steps of cell name, cell standard, geographical longitude where the cell is located, geographical latitude where the cell is located, cell direction angle, adjacent cells in a system and adjacent cells of an inter-system (such as 2G-3G, 2G-4G, 3G-2G, 3G-4G, 4G-2G and 4G-3G). The neighbor cell in the system, that is, the original neighbor cell, the neighbor cell in the different system, that is, the neighbor cell outside the serving cell system, the neighbor cell in the system and the neighbor cell in the different system can be configured already when the base station is turned on, and once the terminal network-resident serving cell is successful (i.e., network access or network residence is successful), the neighbor cell information including the neighbor cell in the system or outside the system can be obtained. The neighbor cell information corresponding to the inter-system neighbor cell may be obtained when the network camping is successful, or may be sent along with the neighbor cell information when the base station issues the cell measurement configuration, which is not specifically limited herein.

The cell measurement configuration means that the base station notifies a measurement configuration message to a terminal (such as a User Equipment (UE)) through a measurement configuration (measConfig) cell carried by the rrcconnectionreconfiguration message, that is, issues measurement control.

In a specific implementation scenario, the terminal may be a device that provides a VoLTE voice service to a user, where VoLTE is an IMS (IP multimedia subsystem) -based voice service, is an IP data transmission technology, and does not need a 2G/3G network, all services are carried over an LTE network, that is, a 4G network, when the terminal is in a voice call state, for example, in a voice call state based on the VoLTE voice service, since the terminal moves to an area where a serving cell signal quality corresponding to the LTE network is weak, a measurement event for measuring a cell by the terminal, for example, measuring an intra-system neighboring cell or an inter-system neighboring cell under a homologous system, is triggered, and then a measurement report corresponding to the measurement event is generated, and based on the measurement report, handover of a serving cell currently camped on the network, for example, switching the serving cell currently camped on the network (e.g., an LTE cell) to an inter-system neighboring cell (e.g., a GSM cell), the procedure is usually that the terminal adopts Single Radio Voice Call Continuity (SRVCC) to smoothly switch the Voice service over IP of the bearer source network to the target CS domain, so as to maintain the Continuity of the Voice service. In practical application, the SRVCC handover is assisted by the network side, and the terminal can perform inter-system neighbor cell measurement by issuing a B1 or B2 measurement event to the terminal, so that when the intra-system neighbor cell of the terminal in the homologous system is difficult to meet the call requirement, the inter-system cell measurement is performed in time to complete the SRVCC handover, resulting in the terminal finally dropping the network and dropping the call under the condition that the signal strength of the LTE network is weaker and weaker.

In the embodiment of the present application, the "receiving, in a voice call state, a cell measurement configuration issued by a base station corresponding to a serving cell, the cell measurement configuration including a first trigger threshold corresponding to the serving cell and a second trigger threshold of an inter-system neighbor" in a process that the terminal receives a cell measurement configuration issued by the base station corresponding to the serving cell for inter-system cell measurement, includes a specific process that:

after the terminal is successfully registered in the base station corresponding to the serving cell, that is, the terminal is successfully camped in a serving cell, such as a serving cell corresponding to a camped LTE network, and registers with the IMS server, the base station corresponding to the serving cell may send a default measurement configuration list to the terminal, where the list includes one or more measurement events, which measurements are performed by the terminal under which conditions, and a measurement report is generated and reported to the terminal. For example,

1. in the process, the terminal can measure an A2 measurement event, namely, measure the communication quality of the current serving cell, for example, periodically measure the signal quality of the current serving cell, and when the signal quality of the serving cell is lower than a certain threshold (a threshold value corresponding to an A2 measurement event) due to the movement of the terminal, satisfy the condition that an A2 measurement event is reported, generate an A2 measurement report and report the measurement report to a base station;

2. the base station may issue cell measurement for a homogeneous system based on an a2 measurement report, and typically may issue measurement for a different-frequency or a heterogeneous system neighboring cell, for example, the base station issues measurement configuration for an a4 measurement event to the terminal, and the terminal may then measure a different-frequency cell (such as a cell belonging to a different communication frequency band of an LTE network) in the homogeneous system, and when the a4 measurement event does not satisfy a measurement report condition, it may detect that there is no homogeneous system cell (such as an LTE cell) with stronger signal coverage around a serving cell corresponding to the terminal, or may understand that when a neighboring cell in a system of the homogeneous system is difficult to satisfy a call requirement, the base station may issue cell measurement configuration for a B2 measurement event, where the cell measurement configuration includes a first trigger threshold corresponding to the serving cell and a second trigger threshold of the heterogeneous system neighboring cell; for another example, the base station may also directly issue the cell measurement configuration for the B2 measurement event without issuing the a4 measurement event for the inter-frequency cell to the terminal, where the cell measurement configuration is used to instruct the terminal to start measurement on an inter-system neighboring cell.

In the LTE network, the following events are mainly measured: a1 measure Event (Event A1), A2 measure Event (Event A2), A3 measure Event (Event A3), A4 measure Event (Event A4), A5 measure Event (Event A5), and B1 measure Event (Event B1), B2 measure Event (Event B2);

where A2 measures events (Event A2): when the quality of the serving cell signal is lower than a certain threshold (a threshold corresponding to an a2 measurement event), and an a2 measurement event meeting the condition is reported, the base station issues a cell measurement configuration for a B2 measurement event to the terminal, so as to indicate the terminal to start inter-frequency/inter-system measurement;

where A4 measures events (Event A4): the quality of the pilot frequency adjacent cell is higher than a certain threshold quantity, when an event meeting the condition is reported, the base station starts a pilot frequency switching request to switch the current network-residing cell of the terminal from the service cell to the pilot frequency adjacent cell, otherwise, when the condition is not met, the reporting is not triggered;

among them, B2 measures Event (Event B2): when the quality of the serving cell is lower than a certain threshold (e.g., a first trigger threshold) and the quality of the inter-system neighbor cell is higher than a certain threshold (e.g., a second trigger threshold), and a B2 measurement event satisfying this condition is reported, the base station may receive a measurement report corresponding to the B2 measurement event, that is, a B2 measurement report.

The trigger threshold may be understood as a threshold value used to measure the signal quality of a cell. The first trigger threshold and the second trigger threshold are thresholds issued by a communication network side (e.g., a base station side corresponding to a serving cell) in a measurement event B2, where the first trigger threshold is a threshold of signal quality of the serving cell, and when the signal quality corresponding to the serving cell meets the first trigger threshold, if the reference signal received power measured by the serving cell is less than the first trigger threshold, the communication quality of the serving cell is usually not good, and a terminal continuously resides in the serving cell and may have a risk of call drop.

The second trigger threshold is a threshold of the signal quality of the inter-system neighbor cell, and when the signal quality corresponding to the inter-system neighbor cell meets the second trigger threshold, for example, when the received signal strength value measured by the inter-system neighbor cell is greater than the second trigger threshold, the communication quality of the inter-system neighbor cell is generally good, which can meet the requirement of the terminal voice call service on the communication network quality, and the terminal can switch the currently resident serving cell to the inter-system neighbor cell.

Further, when the signal quality corresponding to the serving cell generally meets the first trigger threshold and the signal quality corresponding to the inter-system neighbor cell generally meets the second trigger threshold, the communication quality of the serving cell is not good, and the communication quality of the inter-system neighbor cell is good, at this time, the reporting condition of the B2 measurement event is met, a corresponding measurement report is generated, and the measurement report is triggered to be reported to the base station corresponding to the serving cell.

Step S102: and acquiring first signal quality of the service cell and second signal quality of the inter-system neighbor cell.

Specifically, the terminal receives cell measurement configuration delivered by inter-system neighbor cell measurement (i.e., B2 measurement event) delivered by a base station corresponding to a serving cell, and a first trigger threshold corresponding to the serving cell and a second trigger threshold of the inter-system neighbor cell, at this time, the terminal may determine the inter-system neighbor cell to be measured according to the received signal strength of each cell, and then obtain a first signal quality of the serving cell and a second signal quality of the inter-system neighbor cell. The first signal quality and the second signal quality are used for the terminal to measure whether to report the B2 measurement event. Further, when the first signal quality of the serving cell measured by the terminal satisfies the first trigger threshold and the second signal quality of the inter-system neighbor measured by the terminal satisfies the second trigger threshold, in the related art, the terminal may generate a B2 measurement report for a B2 measurement event, where the B2 measurement report is used to instruct the base station to switch the currently camped cell from the serving cell to the inter-system neighbor.

In practical application, the cell measurement configuration received by the terminal and transmitted by the base station may include a neighbor cell list, a report configuration, a measurement identifier, a measurement interval, a quantity identifier, a decision threshold parameter, and the like. The inter-system adjacent cell to be measured can be determined based on the issued cell measurement configuration terminal. During specific measurement, the terminal may perform cell measurement on the current serving cell and the inter-system neighboring cell to be measured based on a measurement period (e.g., one measurement for 150 ms) indicated by a measurement interval issued by the base station, so as to obtain a first signal quality of the serving cell and a second signal quality of the inter-system neighboring cell.

The first signal quality may be understood as a communication parameter used to measure a condition of the serving cell communication network.

The second signal quality can be understood as a communication parameter for measuring the condition of the inter-system neighbor communication network.

The communication parameters corresponding to the first signal quality and the second signal quality are usually determined before measurement, for example, may be determined according to a cell measurement configuration issued by a base station, and in practical application, the communication parameters are determined according to a parameter type of a decision threshold parameter in the cell measurement configuration, where the decision threshold parameter is a first trigger threshold and a second trigger threshold.

In a practical application environment, the first trigger threshold corresponding to the serving cell may be a threshold corresponding to Reference Signal Receiving Power (RSRP), that is, b2_ threshold1_ RSRP; the second trigger threshold corresponding to the inter-system neighboring cell may be a threshold corresponding to a Received signal strength value (RSSI), that is, b2_ threshold2_ GERAN, based on b2_ threshold1_ RSRP and b2_ threshold2_ GERAN, at this time, the terminal needs to measure a first signal quality of the current serving cell, that is, reference signal Received power, and measure a second signal quality of the inter-system neighboring cell to be measured, that is, the signal strength value, in a measurement period (for example, 150ms is measured once), and after the measurement is completed, the terminal may obtain the first signal quality of the serving cell and the second signal quality of the inter-system neighboring cell.

In a specific implementation scenario, if the terminal detects in real time that the signal strength RSRP of the serving cell corresponding to the LTE network is smaller than the current preset threshold during the VoLTE voice call of the terminal, it indicates that the terminal may be far away from the coverage area of the serving cell corresponding to the LTE network or in the edge area of the serving cell corresponding to the LTE network, and the terminal triggers a condition that an a2 measurement event is reported to generate an a2 measurement report and reports the measurement report to the base station. Then, the terminal receives cell measurement configuration issued by a serving cell base station in a VoLTE voice call state, and starts cell measurement on a current serving cell and an inter-system neighbor cell based on the cell measurement configuration terminal, so as to obtain first signal quality of the serving cell and second signal quality of the inter-system neighbor cell, wherein the first signal quality is used as RSRP and the second signal quality is used as RSSI for detailed explanation for convenience of explanation. The following were used:

the terminal performs parameter matching with a first trigger threshold B2_ threshold1_ RSRP and a second trigger threshold B2_ threshold2_ GERAN based on the first signal quality RSRP and the second signal quality RSSI, and determines whether the reporting condition of the B2 measurement event is met, that is, whether the first signal quality RSRP of the terminal detection serving cell is lower than the first trigger threshold B2_ threshold1_ RSRP, and whether the second signal quality of the inter-system neighbor cell is higher than the second trigger threshold B2_ threshold2_ GERAN.

1. When the first signal quality RSRP of the serving cell is less than the first trigger threshold B2_ threshold1_ RSRP and the second signal quality RSSI of the inter-system neighbor is greater than the second trigger threshold B2_ threshold2_ GERAN, the terminal meets the reporting condition of the B2 measurement event, the terminal may generate a measurement report including the first signal quality RSRP and the second signal quality RSSI and upload the measurement report to a base station corresponding to the serving cell, where the B2 measurement report is used to instruct the base station to switch the current camped cell from the serving cell to the inter-system neighbor.

2. When the first signal quality RSRP of the serving cell is less than the first trigger threshold B2_ threshold1_ RSRP and the second signal quality RSSI of the inter-system neighbor cell is less than the second trigger threshold B2_ threshold2_ GERAN, in the related art, the B2 measurement event is not reported because the reporting condition of the B2 measurement event is not satisfied.

The measurement performed by the terminal on the inter-system neighbor cell includes but is not limited to: and measuring the carrier frequency, the pilot signal strength, the pilot signal quality and the like of the adjacent cells of the different systems.

Step S103: determining that the first signal quality is smaller than the first trigger threshold and the second signal quality is smaller than the second trigger threshold, and obtaining a preset third trigger threshold corresponding to the serving cell, a preset fourth trigger threshold corresponding to the inter-system neighbor cell, or a preset fifth trigger threshold corresponding to the inter-system neighbor cell.

In practical application, it may be that the decision threshold parameter is set unreasonably, and at this time, if the network signal quality corresponding to the current serving cell of the terminal is poor and the network signal quality corresponding to the inter-system neighboring cell is relatively good (i.e., the inter-system neighboring cell can meet the service transmission requirement of the terminal, such as voice call data), the current camping cell is not switched from the serving cell to the inter-system neighboring cell in time, which may cause conditions such as network drop, call delay, and the like. In the embodiment of the present application, by executing the network cell handover method, the terminal determines that the first signal quality is less than the first trigger threshold and the second signal quality is less than the second trigger threshold, that is, in step S102, "the first signal quality RSRP of the serving cell is less than the first trigger threshold b2_ threshold1_ RSRP, and the second signal quality RSSI of the inter-system neighbor cell is less than the second trigger threshold b2_ threshold2_ GERAN".

At this time, the terminal may continue to perform secondary cell quality determination based on a preset third trigger threshold corresponding to the serving cell and a preset fourth trigger threshold corresponding to the inter-system neighbor cell, or based on a preset third trigger threshold corresponding to the serving cell and a preset fifth trigger threshold corresponding to the inter-system neighbor cell. When acquiring the preset trigger threshold corresponding to the inter-system neighboring cell, the terminal may choose one of the fourth trigger threshold and the fifth trigger threshold to perform secondary cell quality judgment, and the specific judgment may be defined by the following relevant explanations of the steps.

After the secondary cell quality decision is passed, the terminal may generate a measurement report including the first signal quality and the second signal quality, and then report the measurement report to the base station corresponding to the serving cell. The B2 measurement report is used to instruct the base station to switch the current camping cell from the serving cell to the inter-system neighboring cell.

The trigger threshold may be understood as a threshold value used to measure the signal quality of a cell. The third trigger threshold, the fourth trigger threshold, and the fifth trigger threshold are thresholds that are pre-stored by the terminal for a terminal side (e.g., a user equipment UE) in a B2 measurement event, where the third trigger threshold is a threshold that is set by the terminal side for signal quality of a serving cell, and when the signal quality corresponding to the serving cell is smaller than the third trigger threshold, for example, when reference signal received power measured by the serving cell is smaller than the third trigger threshold, communication quality corresponding to the serving cell is usually very poor, and there is a very large risk of call drop when the terminal continues to reside in the serving cell. Wherein, the third trigger threshold is smaller than the first trigger threshold issued by a communication network side (e.g. a base station corresponding to a serving cell).

In the embodiment of the present application, the size relationship of each trigger threshold involved in measuring the communication quality of the serving cell may be referred to in fig. 3, and in fig. 3, the size relationship of each trigger threshold is respectively: first trigger threshold > sixth trigger threshold > third trigger threshold.

The fourth trigger threshold and the fifth trigger threshold are thresholds set by the terminal side for the signal quality of the inter-system neighbor cells, and are used for measuring whether the signal quality of the inter-system neighbor cells meets the requirement of cell switching under the condition that the signal quality corresponding to the serving cell is poor. The fourth trigger threshold is less than the second trigger threshold and greater than the fifth trigger threshold.

In the embodiment of the present application, the size relationship of each trigger threshold involved in measuring the communication quality of the inter-system neighbor cell may be referred to in fig. 4, and in fig. 4, the size relationship of each trigger threshold is respectively: second trigger threshold > fourth trigger threshold > fifth trigger threshold.

The terminal side sets a third trigger threshold, a fourth trigger threshold or a fifth trigger threshold, and is convenient for refining the communication conditions of the current service cell and the inter-system neighbor cell under the condition that the judgment threshold value in the B2 measurement event issued by the network side is not met, so as to judge the quality of the secondary cell.

Under the condition that the quality judgment of the secondary cell is passed, the communication quality of the inter-system adjacent cell can meet the requirement of the terminal voice call service on the communication network quality compared with the service cell, and the terminal can switch the current resident service cell to the inter-system adjacent cell.

Step S104: reporting a measurement report containing the first signal quality and the second signal quality to the base station based on the third trigger threshold and the fourth trigger threshold, or based on the third trigger threshold and the fifth trigger threshold, where the measurement report is used to instruct the base station to switch a current camped cell from the serving cell to the inter-system neighbor cell, the third trigger threshold is smaller than the first trigger threshold, and the fourth trigger threshold is smaller than the second trigger threshold and larger than the fifth trigger threshold.

Specifically, the secondary cell quality determination process based on the preset third trigger threshold corresponding to the serving cell and the preset fourth trigger threshold corresponding to the inter-system neighbor cell, or based on the third trigger threshold and the fifth trigger threshold, is as follows:

1. when the terminal determines that the first signal quality is smaller than the first trigger threshold and the second signal quality is smaller than the second trigger threshold, the terminal does not usually meet the reporting condition of a B2 measurement event issued by the base station side at this time, and the terminal may perform secondary cell quality determination based on a third trigger threshold and a fourth trigger threshold, specifically:

the terminal determines whether the first signal quality corresponding to the serving cell is greater than the third trigger threshold, and determines whether the second signal quality corresponding to the inter-system neighbor cell is greater than the fourth trigger threshold, where the third trigger threshold may be-118 dbm, and the fourth trigger threshold may be-90 dbm;

when the first signal quality is greater than the third trigger threshold (e.g., -118dbm) and the second signal quality is greater than the fourth trigger threshold (e.g., -90dbm), the communication quality of the serving cell is poor, and the network signal quality corresponding to the inter-system neighbor is relatively better than that of the serving cell, it can be understood that the inter-system neighbor can satisfy the service transmission requirement of the terminal, such as voice call data. At this time, the terminal may set a second trigger threshold issued by a communication network side (e.g., a base station corresponding to a serving cell) by executing the network cell switching method of the embodiment of the present application, specifically, set the second trigger threshold as the fourth trigger threshold (e.g., -90dbm), where a first signal quality of the serving cell and a second signal quality of an inter-system neighboring cell may meet a reporting condition when a B2 measurement event is reported, and then the base station may generate a measurement report corresponding to a B2 measurement event including the first signal quality and the second signal quality, that is, a B2 measurement report, and report the measurement report is reported to the base station, where the measurement report is used to instruct the base station to switch a current network-camped cell from the serving cell to the inter-system neighboring cell.

2. When the terminal determines that the first signal quality is smaller than the first trigger threshold and the second signal quality is smaller than the second trigger threshold, the terminal does not usually meet the reporting condition of a B2 measurement event issued by the base station side at this time, and the terminal may perform secondary cell quality determination based on a third trigger threshold and the fifth trigger threshold, specifically:

the terminal determines whether the first signal quality corresponding to the serving cell is less than the third trigger threshold, and determines whether the second signal quality corresponding to the inter-system neighbor cell is greater than the fifth trigger threshold, where the third trigger threshold may be-118 dbm, and the fifth trigger threshold may be-95 dbm;

when the first signal quality is less than the third trigger threshold (e.g., -118dbm) and the second signal quality is greater than the fifth trigger threshold (e.g., -95dbm), at this time, the communication quality corresponding to the serving cell is usually very poor, there is a great risk of call drop when the terminal continues to camp on the serving cell, and the network signal quality corresponding to the inter-system neighbor is relatively better than that of the serving cell, it can be understood that the inter-system neighbor can satisfy the service transmission requirement of the terminal, such as voice call data, compared with the serving cell. At this time, the terminal may set a second trigger threshold issued by a communication network side (e.g., a base station corresponding to a serving cell) by executing the network cell switching method of the embodiment of the present application, specifically, set the second trigger threshold to a fifth trigger threshold (e.g., -95dbm), where a first signal quality of the serving cell and a second signal quality of an inter-system neighboring cell may meet a reporting condition when a B2 measurement event is reported, and then the base station may generate a measurement report corresponding to a B2 measurement event including the first signal quality and the second signal quality, that is, a B2 measurement report, and report the measurement report is reported to the base station, where the measurement report is used to instruct the base station to switch a current network-camped cell from the serving cell to the inter-system neighboring cell.

At least one of a third preset trigger threshold corresponding to the serving cell, a fourth preset trigger threshold corresponding to the inter-system neighbor cell, and a fifth preset trigger threshold corresponding to the inter-system neighbor cell is obtained, where the trigger threshold is obtained by obtaining a large amount of communication sample data in an actual communication environment in advance and analyzing the obtained communication sample data by using a statistical method.

In the embodiment of the present application, a terminal receives, in a voice call state, a cell measurement configuration sent by a base station corresponding to a serving cell, where the cell measurement configuration includes a first trigger threshold corresponding to the serving cell and a second trigger threshold of an inter-system neighbor, obtains a first signal quality of the serving cell and a second signal quality of the inter-system neighbor, determines that the first signal quality is less than the first trigger threshold and the second signal quality is less than the second trigger threshold, and when the signal quality of the serving cell satisfies a corresponding decision threshold (i.e., the first trigger threshold) and the signal quality of the inter-system neighbor does not satisfy the corresponding decision threshold (i.e., the second trigger threshold), based on a preset third trigger threshold corresponding to the serving cell and a preset fourth trigger threshold corresponding to the inter-system neighbor, or the third trigger threshold and a preset fifth trigger threshold corresponding to the inter-system neighbor cell. By carrying out secondary network cell switching judgment on the communication quality of the service cell and the inter-system neighbor cell, the measurement report containing the first signal quality and the second signal quality can be reported to the base station under the condition that the network environment of the current service cell is no longer suitable for conversation and the network signal quality corresponding to the inter-system neighbor cell can guarantee conversation with the service cell, and the service cell currently residing in the network is switched to the inter-system neighbor cell in time, so that the timely switching of the service cell in the conversation process is realized, the network environment of the service cell where the terminal is located is prevented from further deterioration or even call drop, the continuity of voice conversation service is guaranteed, and the conversation experience in the voice conversation process is improved.

Referring to fig. 5, fig. 5 is a flowchart illustrating a network cell handover method according to another embodiment of the present application. Specifically, the method comprises the following steps:

step S201: and receiving cell measurement configuration sent by a base station corresponding to a service cell in a voice call state, wherein the cell measurement configuration comprises a first trigger threshold corresponding to the service cell and a second trigger threshold of an inter-system neighboring cell.

Specifically, refer to step S101, which is not described herein again.

Step S202: and acquiring first signal quality of the serving cell and second signal quality of the inter-system neighbor cell, and determining that the first signal quality is smaller than the first trigger threshold and the second signal quality is smaller than the second trigger threshold.

Specifically, refer to steps S102 to S103, which are not described herein.

Step S203: acquiring current state information of a terminal, and acquiring at least one original trigger threshold value of a preset original third trigger threshold value corresponding to the serving cell, a preset original sixth trigger threshold value corresponding to the serving cell, a preset original fourth trigger threshold value corresponding to the inter-system neighboring cell, and a preset original fifth trigger threshold value corresponding to the inter-system neighboring cell.

In the embodiment of the present application, the terminal may obtain the current state information to perform threshold optimization on at least one original trigger threshold, that is, perform optimization processing on the original trigger threshold, so as to obtain at least one relatively accurate trigger threshold.

The state information may be speed information, and it can be understood that when the terminal moves relatively fast, frequent cell switching (switching of cells of the same communication system or different systems) may be involved, for example, when the terminal held by the user is riding on a vehicle such as a high-speed rail, a motor car, and an automobile, the speed information of the terminal may affect the accuracy of the original trigger threshold; the state information can be magnetic field parameters, namely parameters representing the characteristics of a magnetic field where the terminal is located, such as magnetic field intensity, magnetic induction intensity, exciting current, induced magnetic flux and the like, and when an external magnetic field exists to interfere with the terminal voice call process, for example, strong magnetic devices (such as magnets and other magnetic objects) exist around the terminal, the terminal can influence the accuracy degree of an original trigger threshold value; the state information can be a geographical position, and when the terminal is located in a basement, an underground parking lot and a dense building, the accuracy of an original trigger threshold value can be influenced; and so on.

The status information may be a fit of one or more of the above, and is not particularly limited herein.

Step S204: and optimizing the original trigger threshold based on the state information to obtain the trigger threshold corresponding to the original trigger threshold after optimization.

One way of optimizing may be: setting corresponding weighting factors (the weighting factors can be negative numbers) aiming at the state parameters corresponding to one or more types of state information, carrying out weighted summation operation on each state parameter and the weighting factors corresponding to the state parameters to obtain an optimized value (the optimized value can be a negative number) after weighted summation, and then adding an original trigger threshold value and the optimized value to obtain the trigger threshold value corresponding to the original trigger threshold value after optimized processing. Such as: and optimizing the original trigger threshold value based on the magnetic field parameter and the speed parameter to obtain an optimized value after weighted summation, and adding the original trigger threshold value and the optimized value, namely the trigger threshold value after optimization processing.

An optimization processing mode can be that, corresponding addition and respective setting reference values are set for state parameters corresponding to one or more types of state information, a reference coefficient is determined based on the state parameters, if the ratio of the state parameters to the reference values corresponding to the state parameters is used as a reference coefficient, and if a plurality of coefficients are set, each coefficient corresponds to a numerical value range, the falling numerical value range is determined according to the state parameters, and then the corresponding coefficient, namely the reference coefficient is determined, and the product of the reference coefficient and the reference value is used as an optimization value; and then, the original trigger threshold and the optimized value (when the optimized value is multiple, namely, the optimized value is added with the multiple optimized values) are used for obtaining the trigger threshold corresponding to the original trigger threshold after the optimization processing. Such as: and optimizing the original trigger threshold based on the magnetic field parameter and the speed parameter, taking the ratio of the magnetic field parameter to a reference value corresponding to the magnetic field parameter as a magnetic field reference coefficient, calculating a magnetic field optimized value corresponding to the magnetic field reference coefficient and the reference value, taking the ratio of the speed parameter to a reference value corresponding to the speed parameter as a speed reference coefficient, calculating a speed optimized value corresponding to the speed reference coefficient and the reference value, and adding the speed optimized value, the magnetic field optimized value and the original trigger threshold to obtain the trigger threshold corresponding to the original trigger threshold after optimization.

In a specific implementation scenario, the terminal inputs state information (such as speed parameters, magnetic field parameters, geographic position parameters, and the like) into a pre-trained threshold optimization model, outputs an optimized value, and optimizes the original trigger threshold based on the optimized value. Such as: optimizing the original trigger threshold based on the magnetic field parameters and the mechanical wear parameters to obtain an optimized value output by a threshold optimization model, and adding the original trigger threshold and the optimized value, namely the trigger threshold after optimization processing; for another example: and optimizing the original trigger threshold based on the magnetic field parameter and the speed parameter to obtain an optimized value output by a threshold optimization model, and adding the original trigger threshold and the optimized value, namely the trigger threshold after optimization processing.

The method comprises the steps of obtaining a large amount of sample data in advance, extracting characteristic information, marking the sample data, and creating an initial threshold optimization model, wherein the characteristic information comprises at least one of state parameters corresponding to state information such as magnetic field parameters, speed parameters and geographic position parameters. The threshold optimization model may be obtained by training an initial threshold optimization model using a large amount of sample data, and for example, the threshold optimization model may be implemented based on one or more of LR (Logistic Regression), SVM (Support Vector Machine), decision tree, naive bayes classifier, CNN (Convolutional Neural Network), RNN (recursive Neural Network), and the like, and the initial threshold optimization model is trained based on the sample data to which an optimization value has been labeled, so that a trained threshold optimization model can be obtained.

Furthermore, in this embodiment, an initial threshold optimization model is created by using a DNN-HMM model introducing an error back propagation algorithm, after extracting feature information, the feature information is input into the neural network model in the form of feature vectors, a training process of the neural network model generally consists of a forward propagation process and a back propagation process, in the forward propagation process, feature information corresponding to terminal input sample data is transmitted from an input layer of the neural network model to an output layer after a transfer function (also called an activation function, a transfer function) operation of hidden layer neurons (also called nodes), wherein each layer of neuron state affects a next layer of neuron state, an actual output value-first speech identifier is calculated in the output layer, an expected error between the actual output value and an expected output value is calculated, parameters of the neural network model are adjusted based on the expected error, the parameters comprise the weight value and the threshold value of each layer, and after training is completed, a threshold value optimization model is generated.

Specifically, the desired error may be a mean square error MSE, which may be obtained by calculating a mean square error MSE between the actual output value and the desired output value, where the mean square error MSE may use the following formula:

wherein m is the number of output nodes, p is the number of training samples, is an expected output value, and is an actual output value.

Step S205: and when the first signal quality is greater than the sixth trigger threshold and less than the first trigger threshold and the second signal quality is greater than the fourth signal quality, continuing to camp on the serving cell.

In practical application, when performing secondary cell quality determination on the serving cell and the inter-system neighboring cell in the B2 measurement event, the terminal may further set a threshold value, that is, the sixth trigger threshold value, greater than the third trigger threshold value and smaller than the first trigger threshold value, for the signal quality of the serving cell. The sixth trigger threshold is used for judging the condition that the signal quality of the serving cell is equivalent to that of the inter-system neighbor cell, or the signal quality of the serving cell is superior to that of the inter-system neighbor cell, and at this time, the report of a B2 measurement event does not need to be triggered. The sixth trigger threshold is greater than the third trigger threshold and less than the first trigger threshold, e.g., -115 dbm.

Specifically, when the first signal quality of the serving cell is greater than the sixth trigger threshold (e.g., -115dbm) and less than the first trigger threshold, and the second signal quality of the inter-system neighbor is greater than the fourth signal quality, the signal quality of the communication network corresponding to the serving cell and the inter-system neighbor is generally equivalent to each other, or the signal quality of the serving cell is superior to the signal quality of the communication network corresponding to the inter-system neighbor, the difference between the call effects of the terminal performing the voice call based on the serving cell and the voice call based on the inter-system neighbor is not large, and the terminal does not need to trigger the report of the B2 measurement event, and further does not need to trigger the handover of the base station side to the serving cell in which the terminal is currently camped.

Further, when the first signal quality of the serving cell is less than the first trigger threshold and the second signal quality of the inter-system neighbor is less than the second trigger threshold, the terminal may not need to trigger the report of the B2 measurement event when detecting that the first signal quality of the serving cell is greater than the sixth trigger threshold (e.g., -115dbm) and less than the first trigger threshold.

Step S206: when the first signal quality is greater than the third trigger threshold and less than a preset sixth trigger threshold corresponding to the serving cell, and the second signal quality is greater than the fourth trigger threshold, setting the second trigger threshold to the fourth trigger threshold to trigger reporting of a measurement report including the first signal quality and the second signal quality to the base station.

Specifically, when determining that the first signal quality is smaller than the first trigger threshold and the second signal quality is smaller than the second trigger threshold, the terminal does not usually meet the reporting condition of a B2 measurement event issued by the base station side at this time, and the terminal may perform secondary cell quality determination based on a third trigger threshold, a sixth trigger threshold, and the fourth trigger threshold, specifically:

the terminal determines whether the first signal quality corresponding to the serving cell is greater than the third trigger threshold and less than a preset sixth trigger threshold corresponding to the serving cell, and determines whether the second signal quality corresponding to the inter-system neighbor is greater than the fourth trigger threshold, where the third trigger threshold may be-118 dbm, the fourth trigger threshold may be-90 dbm, and the sixth trigger threshold may be-115 dbm;

when the first signal quality is greater than the third trigger threshold (e.g., -118dbm) and is less than a preset sixth trigger threshold (e.g., -115dbm) corresponding to the serving cell, and the second signal quality is greater than the fourth trigger threshold (e.g., -90dbm), at this time, the communication quality of the serving cell is poor, and the network signal quality corresponding to the inter-system neighbor cell is relatively good with respect to the serving cell, it can be understood that the inter-system neighbor cell can satisfy the service transmission requirement of the terminal, such as voice call data. At this time, the terminal may set a second trigger threshold issued by a communication network side (e.g., a base station corresponding to a serving cell) by executing the network cell switching method of the embodiment of the present application, specifically, set the second trigger threshold as the fourth trigger threshold (e.g., -90dbm), where a first signal quality of the serving cell and a second signal quality of an inter-system neighboring cell may meet a reporting condition when a B2 measurement event is reported, and then the base station may generate a measurement report corresponding to a B2 measurement event including the first signal quality and the second signal quality, that is, a B2 measurement report, and report the measurement report is reported to the base station, where the measurement report is used to instruct the base station to switch a current network-camped cell from the serving cell to the inter-system neighboring cell.

In a specific embodiment, when the terminal generates a measurement report corresponding to the B2 measurement event, the terminal may further perform optimization processing on the measurement parameters in the measurement report. Specifically, the terminal may perform optimization processing on the second signal quality based on the second trigger threshold to obtain a target second signal quality greater than the second trigger threshold; the target second signal quality is a parameter value which is obtained after optimization processing based on the second signal quality and is larger than a second trigger threshold value. It is to be understood that, the terminal optimizes the second signal quality so that the target second signal quality after the optimization process can satisfy the handover requirement of the network side (e.g. the base station of the serving cell) for the inter-system neighbor quality in the B2 measurement event, and after obtaining the target second signal quality after the optimization process, the terminal may regard the target second signal quality as the second signal quality and generate the measurement report including the first signal quality and the target second signal quality. And then reporting a measurement report corresponding to the B2 measurement event to the base station, and after receiving the measurement report, the base station performs single-standby wireless voice call continuity (SRVCC) switching, namely, switching the current network-residing cell of the terminal from the service cell to the inter-system neighboring cell, so as to transmit voice call service data in the inter-system neighboring cell.

The detailed description of the specific handover procedure is as follows, as shown in fig. 6, fig. 6 is a schematic view of a cell handover scenario.

1. A handover preparation process: the terminal reports the measurement report to the base station of the serving cell, and after receiving the measurement report, the base station of the serving cell may make a handover decision, where the handover decision usually is that a network side (such as a base station and other network devices) determines whether a different system neighboring cell to be handed over is loaded, and determines whether the terminal is allowed to access the different system neighboring cell according to the load condition, where the handover decision process of the network side may refer to a handover decision flow in the related art, and is not described herein again.

2. A handover preparation process: and after the switching judgment is passed, the base station of the service cell sends a switching request to the different system neighbor cell, and after the different system neighbor cell access control, the base station returns a switching access reply.

3. And a switching execution process: the service cell sends a reconfiguration message carrying a switching command to the terminal, and after the terminal receives the reconfiguration message, the random access process is carried out on the adjacent cell of the different system according to the random access resource carried in the reconfiguration message; meanwhile, the service cell transmits cache data (such as cache data related to voice call service) to the inter-system neighbor cell.

4. And a switching completion process: after the terminal is successfully accessed to the different-system adjacent cell randomly, the different-system adjacent cell sends a path switch request to a Mobility Management Entity (MME), the MME sends a bearer modification signaling to a service Gateway, the MME replies the different-system adjacent cell after completing the path switch, and the different-system adjacent cell sends a terminal context release signaling to a service cell. Therefore, the whole SRVCC switching process is completed, the voice call is carried from the PS domain corresponding to the service cell to the CS domain corresponding to the different system neighbor cell, and the continuity of the voice service is ensured.

Step S207: when the first signal quality is less than the third trigger threshold and the second signal quality is greater than the fifth trigger threshold, setting the second trigger threshold to the fifth trigger threshold to trigger reporting of a measurement report including the first signal quality and the target second signal quality to the base station.

Specifically, when the terminal determines that the first signal quality is smaller than the first trigger threshold and the second signal quality is smaller than the second trigger threshold, the terminal does not usually meet the reporting condition of a B2 measurement event issued by the base station side at this time, and the terminal may perform secondary cell quality determination based on a third trigger threshold and the fifth trigger threshold, specifically:

when the first signal quality is less than the third trigger threshold (e.g., -118dbm) and the second signal quality is greater than the fifth trigger threshold (e.g., -95dbm), at this time, the communication quality corresponding to the serving cell is usually very poor, there is a great risk of call drop when the terminal continues to camp on the serving cell, and the network signal quality corresponding to the inter-system neighbor is relatively better than that of the serving cell, it can be understood that the inter-system neighbor can satisfy the service transmission requirement of the terminal, such as voice call data, compared with the serving cell. At this time, the terminal may set a second trigger threshold issued by a communication network side (e.g., a base station corresponding to a serving cell) by executing the network cell handover method of the embodiment of the present application, specifically, set the second trigger threshold to a fifth trigger threshold (e.g., -95dbm), where a first signal quality of the serving cell and a second signal quality of an inter-system neighboring cell may meet a reporting condition when a B2 measurement event is reported, and then may generate a measurement report corresponding to a B2 measurement event including the first signal quality and a target second signal quality, that is, a B2 measurement report, and report the measurement report is reported to the base station, where the measurement report is used to instruct the base station to handover a current camped cell from the serving cell to the inter-system neighboring cell.

Step S208: and determining that the first signal quality is smaller than the first trigger threshold and the second signal quality is smaller than the fifth trigger threshold, and acquiring at least one resident historical inter-system cell.

The historical inter-system cell may be understood as an inter-system cell which is camped or accessed before camping or accessing the serving cell.

Specifically, when the terminal determines that the first signal quality is smaller than the first trigger threshold and the second signal quality is smaller than the fifth trigger threshold, the inter-system neighboring cell corresponding to the serving cell does not meet the cell handover condition, and the terminal may obtain at least one resident historical inter-system cell.

In practical application, a terminal stores a history resident cell list, where the history resident cell list includes cells belonging to the same communication system as a current serving cell and cells belonging to different systems, which do not belong to the same communication system. The at least one history inter-system cell where the terminal acquires the camping may be acquired in a history camping cell list, that is, the history inter-system cell which is not the same communication system as the current serving cell is acquired in the history camping cell list. If the current serving cell is an LTE communication system, the terminal may acquire a history resident cell under the GSM communication system.

In this embodiment of the present application, when a communication operator builds a service cell, a neighbor cell of a different system is determined, that is, the service cell may correspond to a neighbor cell list of the service cell, where the neighbor cell list may include neighbor cells of the same communication system and different system neighbor cells, and when a cell handover event is involved (e.g., a B2 measurement event), when a base station of the service cell issues a cell measurement configuration to a terminal, the cell measurement configuration may include information of the different system neighbor cells, it may be understood that, according to some implementations, the number of the different system neighbor cells may be multiple, and when a measurement report is reported according to a B2 measurement event, the measurement report may include measurement results of the multiple different system neighbor cells; and the information of the historical different system cells is acquired by the terminal in the stored historical resident cell list.

In a specific embodiment, in step S205, when the first signal quality is greater than the sixth trigger threshold and less than the first trigger threshold, and the second signal quality is greater than the fourth signal quality, "one way may be that the terminal continues to camp on the serving cell as in step S205. One way may be that the terminal acquires at least one resident historical inter-system cell, determines a target inter-system cell from each of the historical inter-system cells, uses the target inter-system cell as the inter-system neighboring cell, and then executes the step S202. In other words, under such a condition, the terminal can take the target inter-system neighbor cell in the at least one history inter-system neighbor cell into reference, and can switch the target inter-system neighbor cell when the target inter-system neighbor cell meets the network cell switching condition, so that continuity of voice call service is further ensured, and call experience in the voice call process is improved.

Step S209: and determining a target inter-system cell from each historical inter-system cell, and taking the target inter-system cell as the inter-system neighbor cell.

In practical application, the inter-system neighboring cell which has been measured by the terminal and the cell in the history resident cell list may have the same history resident cell, and the terminal filters the inter-system neighboring cell which has been measured in each history inter-system cell before determining the target inter-system cell, that is, the inter-system neighboring cell is not included in the reference range of the target inter-system cell.

Specifically, the method for the terminal to determine the target inter-system cell may be: the terminal acquires network performance parameters of each historical inter-system cell, determines the cell priority of the historical inter-system cell according to the network performance parameters, determines a target inter-system cell indicated by the highest cell priority in each historical inter-system cell, and takes the target inter-system cell as the inter-system neighboring cell, and then executes the step S202.

The terminal may determine the cell priority of the historical inter-system cell according to the high-low order of the network performance parameters, for example, the terminal may measure the signal power of each historical inter-system cell, and determine the cell priority of the historical inter-system cell according to the high-low order of the signal power; for example, the terminal may measure signal strength values of the historical different-system cells, determine cell priorities of the historical different-system cells according to the high-low order of the signal strength values, and the like.

Wherein the network performance parameter includes, but is not limited to, at least one of Reference Signal Receiving Power (RSRP) of the historical heterogeneous system cell, Received Signal Code Power (RSCP), Ratio of received chip Signal strength and Noise strength (EcIo) of the received Signal to spectral density of Noise (EcNo)/Signal-to-Noise Ratio (Signal-to-Noise Ratio, SNR)/Reference Signal Receiving quality (Reference Signal Receiving quality, RSRQ), Bit Error Rate (Bit Error Ratio, BER)/block Error Rate (Blocker Rate, BLER)/Packet Error Rate (Packet Error Ratio, PER), and the like to realize Signal quality evaluation of the current historical heterogeneous system cell, of course, other parameters may be measured to perform signal quality evaluation on the current historical inter-system cell.

In the embodiment of the present application, a terminal receives, in a voice call state, a cell measurement configuration sent by a base station corresponding to a serving cell, where the cell measurement configuration includes a first trigger threshold corresponding to the serving cell and a second trigger threshold of an inter-system neighbor, obtains a first signal quality of the serving cell and a second signal quality of the inter-system neighbor, determines that the first signal quality is less than the first trigger threshold and the second signal quality is less than the second trigger threshold, and when the signal quality of the serving cell satisfies a corresponding decision threshold (i.e., the first trigger threshold) and the signal quality of the inter-system neighbor does not satisfy the corresponding decision threshold (i.e., the second trigger threshold), based on a preset third trigger threshold corresponding to the serving cell and a preset fourth trigger threshold corresponding to the inter-system neighbor, or the third trigger threshold and a preset fifth trigger threshold corresponding to the inter-system neighbor cell.

In addition, the network cell switching apparatus and the network cell switching method provided in the foregoing embodiments belong to the same concept, and details of implementation processes thereof are referred to in the method embodiments and are not described herein again.

The above-mentioned serial numbers of the embodiments of the present application are merely for description and do not represent the merits of the embodiments.

The present application further provides a computer program product, where at least one instruction is stored in the computer program product, and the at least one instruction is loaded by the processor and executes the network cell handover method according to the embodiments shown in fig. 1 to fig. 6, where a specific execution process may refer to specific descriptions of the embodiments shown in fig. 1 to fig. 6, and is not described herein again.

Referring to fig. 12, a block diagram of an electronic device according to an exemplary embodiment of the present application is shown. The electronic device in the present application may comprise one or more of the following components: a processor 110, a memory 120, an input device 130, an output device 140, and a bus 150. The processor 110, memory 120, input device 130, and output device 140 may be connected by a bus 150.

Processor 110 may include one or more processing cores. The processor 110 connects various parts within the overall electronic device using various interfaces and lines, and performs various functions of the electronic device 100 and processes data by executing or executing instructions, programs, code sets, or instruction sets stored in the memory 120 and calling data stored in the memory 120. Alternatively, the processor 110 may be implemented in hardware using at least one of Digital Signal Processing (DSP), field-programmable gate Array (FPGA), and Programmable Logic Array (PLA). The processor 110 may integrate one or more of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a modem, and the like. Wherein, the CPU mainly processes an operating system, a user interface, an application program and the like; the GPU is used for rendering and drawing display content; the modem is used to handle wireless communications. It is understood that the modem may not be integrated into the processor 110, but may be implemented by a communication chip.

The Memory 120 may include a Random Access Memory (RAM) or a read-only Memory (ROM). Optionally, the memory 120 includes a non-transitory computer-readable medium. The memory 120 may be used to store instructions, programs, code sets, or instruction sets. The memory 120 may include a program storage area and a data storage area, wherein the program storage area may store instructions for implementing an operating system, instructions for implementing at least one function (such as a touch function, a sound playing function, an image playing function, etc.), instructions for implementing various method embodiments described below, and the like, and the operating system may be an Android (Android) system, including a system based on Android system depth development, an IOS system developed by apple, including a system based on IOS system depth development, or other systems. The data storage area may also store data created by the electronic device during use, such as phone books, audio and video data, chat log data, and the like.

Referring to fig. 13, the memory 120 may be divided into an operating system space, in which an operating system runs, and a user space, in which native and third-party applications run. In order to ensure that different third-party application programs can achieve a better operation effect, the operating system allocates corresponding system resources for the different third-party application programs. However, the requirements of different application scenarios in the same third-party application program on system resources are different, for example, in a local resource loading scenario, the third-party application program has a higher requirement on the disk reading speed; in the animation rendering scene, the third-party application program has a high requirement on the performance of the GPU. The operating system and the third-party application program are independent from each other, and the operating system cannot sense the current application scene of the third-party application program in time, so that the operating system cannot perform targeted system resource adaptation according to the specific application scene of the third-party application program.

In order to enable the operating system to distinguish a specific application scenario of the third-party application program, data communication between the third-party application program and the operating system needs to be opened, so that the operating system can acquire current scenario information of the third-party application program at any time, and further perform targeted system resource adaptation based on the current scenario.

Taking an operating system as an Android system as an example, programs and data stored in the memory 120 are as shown in fig. 14, and a Linux kernel layer 320, a system runtime library layer 340, an application framework layer 360, and an application layer 380 may be stored in the memory 120, where the Linux kernel layer 320, the system runtime library layer 340, and the application framework layer 360 belong to an operating system space, and the application layer 380 belongs to a user space. The Linux kernel layer 320 provides underlying drivers for various hardware of the electronic device, such as a display driver, an audio driver, a camera driver, a bluetooth driver, a Wi-Fi driver, power management, and the like. The system runtime library layer 340 provides a main feature support for the Android system through some C/C + + libraries. For example, the SQLite library provides support for a database, the OpenGL/ES library provides support for 3D drawing, the Webkit library provides support for a browser kernel, and the like. Also provided in the system runtime library layer 340 is an Android runtime library (Android runtime), which mainly provides some core libraries that can allow developers to write Android applications using the Java language. The application framework layer 360 provides various APIs that may be used in building an application, and developers may build their own applications by using these APIs, such as activity management, window management, view management, notification management, content provider, package management, session management, resource management, and location management. At least one application program runs in the application layer 380, and the application programs may be native application programs carried by the operating system, such as a contact program, a short message program, a clock program, a camera application, and the like; or a third-party application developed by a third-party developer, such as a game application, an instant messaging program, a photo beautification program, a network cell switching program, and the like.

Taking an operating system as an IOS system as an example, programs and data stored in the memory 120 are shown in fig. 15, and the IOS system includes: a Core operating system Layer 420(Core OS Layer), a Core Services Layer 440(Core Services Layer), a Media Layer 460(Media Layer), and a touchable Layer 480(Cocoa Touch Layer). The kernel operating system layer 420 includes an operating system kernel, drivers, and underlying program frameworks that provide functionality closer to hardware for use by program frameworks located in the core services layer 440. The core services layer 440 provides system services and/or program frameworks, such as a Foundation framework, an account framework, an advertisement framework, a data storage framework, a network connection framework, a geographic location framework, a motion framework, and so forth, as required by the application. The media layer 460 provides audiovisual related interfaces for applications, such as graphics image related interfaces, audio technology related interfaces, video technology related interfaces, audio video transmission technology wireless playback (AirPlay) interfaces, and the like. Touchable layer 480 provides various common interface-related frameworks for application development, and touchable layer 480 is responsible for user touch interaction operations on the electronic device. Such as a local notification service, a remote push service, an advertising framework, a game tool framework, a messaging User Interface (UI) framework, a User Interface UIKit framework, a map framework, and so forth.

In the framework shown in FIG. 15, the framework associated with most applications includes, but is not limited to: a base framework in the core services layer 440 and a UIKit framework in the touchable layer 480. The base framework provides many basic object classes and data types, provides the most basic system services for all applications, and is UI independent. While the class provided by the UIKit framework is a basic library of UI classes for creating touch-based user interfaces, iOS applications can provide UIs based on the UIKit framework, so it provides an infrastructure for applications for building user interfaces, drawing, processing and user interaction events, responding to gestures, and the like.

The Android system can be referred to as a mode and a principle for realizing data communication between the third-party application program and the operating system in the IOS system, and details are not repeated herein.

In one example, the input device 130 and the output device 140 may be combined, and the input device 130 and the output device 140 are touch display screens for receiving touch operations of a user on or near the touch display screens by using any suitable object such as a finger, a touch pen, and the like, and displaying user interfaces of various applications. Touch displays are typically provided on the front panel of an electronic device. The touch display screen may be designed as a full-face screen, a curved screen, or a profiled screen.
