detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Before describing the embodiments of the present invention, the basic information of interoperability between different network standards will be discussed in detail.

First, let's look at the circumstances under which the UE will interoperate between different network standards.

Specifically, after the UE is powered on, it is in an idle state. At this time, the UE first finds a suitable network for cell selection, reads cell broadcast information (Master Information Block (MIB)/System Information Block (SIB)), and then selects a suitable cell station. Staying, the UE is in standby state at this time. System message or wireless resource The control (RRC) message provides parameters such as the same frequency measurement parameter, the inter-frequency measurement parameter, the heterogeneous measurement parameter, the cell reselection parameter, the cell handover parameter, the measurement report event, and the like. In the standby or RRC connection state, according to the indication of the system message or the RRC message, the UE initiates measurement requests of the same frequency cell, the inter-frequency cell, and the heterogeneous cell. When the signal strength of the serving cell and the neighboring cell meets a certain signal threshold, An event occurs in which a communication system cell is reselected or switched to another communication system cell, enabling the UE to camp and resume services in the best cell, improving and improving the user experience.

Second, let's take a look at the UE's cell selection, reselection process, and handover process.

(1) Cell selection

The first thing that is done after the UE is powered on is to perform cell selection. Specifically, the UE performs measurement on the cell to be selected, performs channel quality evaluation, and then determines whether the cell meets the resident standard according to the S criterion.

For the specific selection process of the LTE cell, refer to the description in section 5.2.3 of the 3GPP TS36.304 protocol; the specific selection process of the Wideband Code Division Multiple Access (WCDMA) cell can refer to the 3GPP TS25.304 protocol 5.2. The description of Section 3; the specific selection process of the Global System for Mobile Communication (GSM) cell can refer to the description of Section 4.5 of the 3GPP TS43.022 protocol.

(2) Cell reselection

In 2G/3G/4G cellular mobile systems, different network standards can set different frequency priorities. Generally, the frequency priority of 4G is the highest, the frequency priority of 3G is second, and the frequency priority of 2G is the lowest. After the UE camps on the cell, it is in an idle state. At this time, if the frequency of the heterogeneous neighboring cell is higher than the frequency of the current serving cell, the UE will always start the high priority frequency measurement. If the frequency priority of the heterogeneous neighboring cell is not higher than the current serving cell frequency priority, the UE will start the measurement of the equal or low priority frequency cell when the signal strength is below a certain threshold. After the UE selects and camps on the cell, it continuously monitors the same-frequency, inter-frequency, and heterogeneous cells so that the UE can It can reside on a cell with higher priority or better channel quality. When the signal strength between the serving cell and the different neighboring cells meets certain threshold conditions, a cell reselection event will occur.

The specific reselection process of the LTE cell may refer to the description in section 5.2.4 of the 3GPP TS36.304 protocol; the specific reselection process of the WCDMA cell may refer to the description of section 5.2.6 of the 3GPP TS 25.304 protocol; the specific reselection of the GSM cell The procedure can be referred to the description in section 4.5 of the 3GPP TS 43.022 protocol.

(3) Cell switching

When the UE is in the connected state, the network implements mobility management of the UE through the handover process. The network sends a measurement control message to the UE through the RRC signaling. When the UE monitors that the signal quality of the serving cell and the neighboring cell meets a certain threshold condition, the measurement report event is triggered to the network. The network determines whether to initiate the handover based on the specific policy, and sends a handover command to the UE when the handover is determined to be initiated, and sends the handover target cell to the UE. After receiving the handover command, the UE switches to the target cell.

For the LTE system, in the connected state, the event that triggers the measurement report has events of A1, A2, A3, A4, A5, A6, B1, and B2, wherein the heterogeneous switching generally adopts the B2 event.

For the WCDMA system, in the connected state, the event that triggers the measurement report has 2A, 2B, 2C, 2D, 2E, 2F, 3A, 3B, 3C events, wherein the heterogeneous switching generally adopts the 3A event.

For the GSM system, when the measured value of the heterogeneous cell (high priority) is higher than a certain threshold, the transmission of the measurement report event will be triggered, and then the network side decides whether to initiate the handover process.

The handover measurement report triggering event of the LTE system may refer to the description in section 5.5.4 of the 3GPP TS36.331 protocol; the handover measurement report triggering event of the WCDMA system may refer to the description of the 3GPP TS25.331 protocol 14.2, section 14.3; handover measurement of GSM The report triggering event can be referred to the description in section 5.2 of the 3GPP TS43.022 protocol.

Cell reselection and cell handover are important contents in UE mobility management. During the UE mobile process, the cell signal strength changes continuously, so the number of reselection and handover is very frequent, and interoperability between different network standards. The performance of the UE greatly affects the normal and stable operation of the UE. Greatly affected the user experience. Therefore, it is necessary to frequently test the interoperability between different network standards to ensure that the UE can still maintain normal and stable operation after many reselections and handovers.

However, the current testing of interoperability between different network standards is mainly achieved by manual, which will greatly reduce the test efficiency.

Based on this, in various embodiments of the present invention, the ATPi controls the different network interoperation control systems of the device according to the test script formed by the test case, and the terminal performs corresponding operations to achieve the number of times set according to the test script. And sequentially test the interoperability between different network standards, and after the test, the test data is summarized and analyzed to generate a test report.

The ATPi 11 is configured to control the different network interoperation control system 12 and the terminal 13 to perform corresponding operations according to the test script formed by the test case, so as to implement different network standards according to the number and sequence set by the test script. Testing the interoperability performance; and performing a summary analysis on the test data reported by the terminal 13 to generate a test report;

The different network interoperation control system 12 is configured to generate, according to the control information sent by the ATP 11 , each inter-network interoperable network environment corresponding to the control information;

The test script can be written in the Tool Command Language (TCL).

In an embodiment, as shown in FIG. 2, the inter-network interoperability control system 12 may include: an OMCR server 121, an attenuation controller 122, and a base station 123 corresponding to each network standard;

The OMCR server 121 interacts with the ATPi 11 based on the IP, and is configured to receive network parameters of each network sent by the ATPi 11 and perform network configuration by using network parameters of each network sent by the ATPi 11 to enable The terminal 13 performs interoperation between the network systems;

The attenuation controller 122 is configured to interact with the ATPi 11 through the serial port, and configured to adjust the signal strength of each network according to the control information sent by the ATPi 11 to trigger the terminal 13 to initiate interoperation;

Correspondingly, the terminal 13 interacts with the ATPi 11 through a USB interface, and is configured to use the base station 123 of the corresponding network system connected to the attenuation controller 122 according to the control information sent by the ATPi 11, and the OMCR server. 121 interacts to implement interoperability between the various network standards.

In the embodiment of the present invention, the interoperability between different network standards is frequently tested, that is, the stress testing is performed frequently on the interoperability between different network standards, so the terminal 13 and the attenuation controller 122 are The connection between the attenuation controller 122 and the base station 123 corresponding to each network standard may be a wired connection, that is, a wired RF (Radio Frequency) channel is formed between the terminal 13 and the attenuation controller 122, and the attenuation controller is formed. A wired RF channel is formed between the base stations 123 corresponding to the respective network standards.

The OMCR server 121 is further configured to: before receiving the network parameters of each network sent by the ATPi 11, verify the legality of the ATPi 11 identity, determine that the ATPi identity is legal, and receive each sent by the ATPi Network parameters of the network.

For example, if the terminal 13 is in an LTE network cell, after switching to the WCDMA network cell according to the handover threshold parameter, the terminal 13 can no longer be handed over to the GSM network cell; and the terminal 13 is assumed to be in the WCDMA network cell. After switching to the LTE network cell according to the handover threshold parameter, it is no longer possible to switch to the GSM network cell; if the terminal 13 is in the LTE network cell, after reselecting to the WCDMA network cell according to the reselection threshold parameter, it cannot be heavy again. Selected to the GSM network cell.

In practical applications, when setting the reselection or handover threshold parameters, parameters such as the hysteresis value of the cell and the individual offset of the cell need to be considered.

The generated interoperation test data may be used as log (LOG) information of the terminal; accordingly, the terminal 13 transmits LOG information to the ATPi 11.

In actual application, the ATPi 11 matches the signaling flow in the LOG information reported by the terminal 13 with the signaling flow set in the test script to determine whether the process is correct; The important signal parameters in the LOG information, draw various dynamic curves, charts, etc., to facilitate fault location analysis and so on. The ATPi 11 performs a summary analysis on the test data reported by the terminal 13, and the specific implementation process of generating the test report can be written into the test script according to the needs of the tester, so that the ATPi 11 follows the The summary analysis in the test script is required to perform a summary analysis of the test data and generate a corresponding test report.

According to the apparatus provided by the embodiment of the present invention, the ATPi 11 controls the different network interoperation control system 12 and the terminal 13 to perform corresponding operations according to the test script formed by the test case, and realizes the number and sequence set according to the test script.

Embodiment 2

The device according to the embodiment of the present invention provides a test method for interoperability between different network standards. As shown in FIG. 3, the method includes the following steps:

Step 301: The ATPi of the test device for interoperability between different network standards controls the different network interoperation control systems of the device and the terminal to perform corresponding operations according to the test script formed by the test case, and implements the setting according to the test script. The number and order of tests for interoperability between different network standards;

Here, in a process of controlling different network interoperation control systems of the device, the terminal performs a corresponding operation, the different network interoperation control system generates a network inter-operating network environment corresponding to the control information of the ATP; The terminal performs interoperation between the network systems and generates corresponding interoperation test data by using the interoperable network environment provided by the different network interoperation control system under the control of the ATPi.

The test script can be written in TCL.

The network interoperability control system generates a network interoperability network environment corresponding to the control information of the ATP, and specifically includes:

The OMCR server of the different network interoperation control system receives the network parameters of each network sent by the ATPi based on the IP, and performs network configuration by using the network parameters, so that the terminal performs mutual interaction among the network standards. operating;

The attenuation controller of the different network interoperation control system adjusts the signal strength of each network according to the control information sent by the ATPi through the serial port, and triggers the terminal to initiate interoperation;

For example, if the terminal is in an LTE network cell, after switching to the WCDMA network cell according to the handover threshold parameter, the terminal cannot be switched to the GSM network cell; and the terminal is assumed to be in the WCDMA network cell. After switching to the LTE network cell according to the handover threshold parameter, the terminal cannot be switched to the GSM network cell; if the terminal is in the LTE network cell, after reselecting to the WCDMA network cell according to the reselection threshold parameter, the GSM cannot be reselected.

Correspondingly, the adjusting the signal strength of each network according to the control information sent by the ATPi is:

The attenuation controller adjusts the attenuation value of the corresponding adjustable attenuation channel according to the control information sent by the ATPi to achieve the purpose of adjusting the signal strength of each network, thereby triggering the terminal to initiate interoperation.

Here, the control information sent to the terminal can be implemented by means of an AT command.

Step 302: The terminal reports the test data to the ATPi; the ATPi performs a summary analysis on the test data to generate a test report.

Here, after generating the test report, the ATPi can present the test report to the tester. Specifically, it can be implemented by sending an email to a tester.

The generated interoperation test data may be used as the LOG information of the terminal; accordingly, the terminal sends the LOG information to the ATPi.

In an actual application, the ATPi uses the signaling flow in the LOG information reported by the terminal to match the signaling flow set in the test script to determine whether the process is correct; and may also use the LOG reported by the terminal. Important signal parameters in the information, draw various dynamic curves, charts, etc., to facilitate fault location analysis and so on. The ATPi performs a summary analysis on the test data reported by the terminal, and the specific implementation process of generating the test report can be written into the test script according to the needs of the tester, so that the ATP will follow the test script. The summary analysis needs to summarize the test data and generate a corresponding test report.

According to the method provided by the embodiment of the present invention, the ATPi controls the different network interoperation control systems and the terminal to perform corresponding operations according to the test script formed by the test case, and realizes different networks according to the number and sequence set by the test script. The inter-system interoperability is tested; and the different network interoperation control system generates and controls according to the control information sent by the ATPi Inter-operating network environment between network systems corresponding to the information; the terminal interoperating between the network systems according to the control information sent by the ATPi, using the interoperable network environment provided by the different network interoperation control system And generating corresponding interoperation test data; sending the test data to the ATPi, and the ATPi performs a summary analysis on the test data reported by the terminal to generate a test report, thereby automatically completing the test process, saving manpower Cost, while greatly improving the efficiency of testing.

In addition, since the test process is completed automatically, the negligence caused by the manual operation is reduced, and the accuracy of the test is greatly improved.

The test script written by ATPi can realize the interoperability (reselection or switching process) between multiple network standards without manual intervention and on-duty, which further improves the testing efficiency.

Embodiment 3

On the basis of the first and second embodiments, this embodiment takes the interoperation between 2G/3G/4G as an example to describe in detail how to implement the interoperability test between different network standards.

First, let's take a look at the current test process for interoperability between 2G/3G/4G. The process of manual testing, as shown in Figure 4, includes the following steps:

Step 401: Set up a test environment and connect the test network elements.

Here, according to the connection relationship shown in FIG. 5, each test network element is connected.

Step 402: The tester configures network parameters of each network on the OMCR server.

Specifically, the configured network parameters include: measurement thresholds of each network, reselection thresholds, handover thresholds, measurement report events, and the like.

Step 403: On the AT command operation interface, the tester sends an AT command to the terminal to control the terminal to be powered on;

Step 404: The tester manually adjusts the attenuation controller so that the attenuation values of the attenuators A, B, and C channels satisfy the condition of cell reselection;

Step 405: The tester initiates a public land mobile network (PLMN, Public Land Mobile Network) search by sending an AT command on the AT command operation interface.

Step 406: Assume that step 404 satisfies the condition that the LTE network cell reselects to the WCDMA/Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network cell. Observe whether the reselection process complies with the requirements of the 3GPP protocol; after a period of time, continue manual adjustment, so that the attenuation values of the attenuators A, B, and C channels satisfy the reselection conditions of the WCDMA/TD network cell to the GSM network cell; Continue manual adjustment so that the attenuation values of the A, B, and C channels of the attenuator satisfy the reselection conditions of the GSM network cell to the LTE network cell. Thus, by adjusting the attenuation values of the attenuators A, B, and C channels, different networks can be implemented.

Next, the process of automatically testing the interoperability between 2G/3G/4G in this embodiment will be described in detail.

The test device for interoperability between different network standards provided by this embodiment is an automatic test device. As shown in FIG. 6 , in the test device, the other devices are mainly controlled by the ATPi, and the ATPi is developed by the TCL. By using the test script written by the TCL, other devices in the test device can be controlled, including: controlling the OMCR. The server, the control of the attenuation controller, and the AT command transmission and response of the control terminal, the FTP service transmission, and the collection of the terminal LOG information. At the same time, ATPi also performs data processing and analysis, test report generation and mail delivery.

Among them, when writing test scripts, you need to include the following:

a) configuration and update of network parameters of each LTE, WCDMA/TD, GSM network;

b) sending an AT command to the terminal to obtain a terminal AT command response;

c) Control the FTP connection between the FTP client and the server of the terminal, and automatically perform FTP upload and download services;

Specifically, the ATPi executes the test script, initiates the test case execution command, and sequentially performs the control flow according to the test script, automatically controls the interaction sequence between the devices, and performs repeated stress testing on the interoperability performance according to the set loop counter. After the test, ATPi automatically generates data analysis As a result, and send a test report to the test manager and test executive engineer.

Among them, ATPi's communication control for other devices includes:

(1) OMCR server

The OMCR server provides a GUI for manual operation and provides the ability to modify parameters for Telent remote login so that the ATPi can communicate with the OMCR based on IP. The brief control of the TCL scripting language is as follows:

Proc ProcLoginOMCR{username password}{ ;#OMCR webmaster login

Verify user name and password, OMCR login succeeded

}

Proc ProcParameterSetting{var1var2}{ ;#OMCR network management parameter modification

Send OMCR control parameters

After the parameter is verified, the OMCR configuration is successful.

}

(2) attenuation controller

The traditional adjustable attenuator is manually controlled. The attenuation controller has 2, 4, 6, 8, 10, 20db attenuation buttons. The signal strength is achieved by pressing or popping up the control button. This attenuator is only suitable for manual control and is not suitable for automated control. The attenuation controller used in this embodiment is a hardware board developed based on CPLD logic. As shown in FIG. 7, the board has 10 adjustable attenuation channels, and each attenuation channel can be in the range of 0 to 60 dBm. Adjustment, up to 10 channels of different standards can be accessed. The attenuation controller of the embodiment communicates with the ATPi through the RS-232 serial port, and reads and writes through the serial port to control the attenuation value of each attenuator path, thereby automatically controlling and adjusting the attenuation of each channel, and completing various scenarios. Select or switch the test.

The TCL scripting language briefly controls the serial port read and write operations of the attenuation controller as follows:

Proc HocComOpen{COM1} ;#Open the serial port and set the baud rate/check digit/data bit/stop bit

Proc HocComRead{COM1} ;#Read attenuator data

Proc HocComWrite{COM1,HOC_data} ;#Write attenuator data

Proc HocComClose{COM1} ;#Close COM1 serial port read and write

(3) Terminal

The ATP and the terminal are connected using a USB interface, and the driver is loaded into a COM serial connection mode. The control information is sent to the terminal by means of an AT command. Sending an AT command to a terminal and reading an AT message are implemented by reading and writing a serial port.

The TCL scripting language controls the terminal through the serial port read and write operations. The brief control method is as follows:

Proc HocComOpen{COM2};#Open the serial port and set the baud rate/check digit/data bit/stop bit

Proc HocComRead{COM2} ;#Read AT feedback information

Proc HocComWrite{COM2,AT_data} ;#Write AT command

Proc HocComClose{COM2} ;#Close COM2 serial port read and write

The process of automated testing, as shown in Figure 8, includes the following steps:

Step 801: The ATPi sends control information to the terminal, and the control terminal is in a shutdown state;

Here, in the following description, an LTE, WCDMA, and GSM network is taken as an example to explain in detail how to perform an automated test.

Step 802: The ATPi sends control information to the attenuation controller to adjust network signal strengths of LTE, WCDMA, and GSM.

Here, in the following description, the LTE network is simply referred to as L, the WCDMA network is simply referred to as W, and the GSM network is simply referred to as G.

Assume that the adjustment is: L: -70dbm, W: -95dbm, G: -95dbm.

Here, the network signal strength refers to a value of Received Signal Code Power (RSCP).

Step 803: The ATPi sends control information to the OMCR server, and configures 2G/3G/4G network parameters.

Specifically, the ATPi logs in to the attenuation controller and inputs a username and password;

The attenuation controller verifies the username and password to verify the legality of the ATPi identity;

After the verification is passed, the ATPi sends the 2G/3G/4G network parameters to the attenuation controller;

The attenuation controller verifies the received 2G/3G/4G network parameters. After the verification is valid, the network configuration is performed using the received 2G/3G/4G network parameters.

Here, the network parameters mainly include related parameters such as reselection, switching, and measurement events.

The reselection or switching threshold parameter is a reselection or switching threshold parameter based on the stability setting of the reselection or switching. In other words, when the reselection or handover threshold parameter is set, it needs to be set according to the stability of reselection or handover, that is, when reselecting or switching to a network cell according to the set reselection or handover threshold parameter, A reselection or switching to another network cell will occur. When setting, the measurement, reselection, and switching thresholds between different standard cells need to be considered comprehensively. Unreasonable thresholds may lead to reselection or unstable switching between systems, such as terminal migration by standard A. After the system B, just stayed on the system B, found that the system C is better, further, the terminal may also occur between the system B and the system C, so that the terminal can not work stably in a system .

In order to avoid such instability of terminal movement, in the embodiment of the present invention, in order to facilitate repeated re-election and switching of pressure performance tests from the perspective of automated testing, re-election and switching measurement of different standard cells in a laboratory environment The limits need to be carefully considered so that the terminal can stay in a network stably at any signal strength of different standard cells, avoiding the uncertainty of reselection or handover. In the embodiment of the present invention, the priority of L is set to be the highest, the priority of W is second, and the priority of G is the lowest.

As shown in Figure 9, the setting of the reselection threshold parameter needs to avoid the instability of reselection. Therefore, it is necessary to consider the constraint relationship between the two signal threshold parameters of W1 and W2, and the two signal thresholds of L1 and L2. The constraint relationship between. In FIG. 9, W1 represents reselection threshold parameters from L cell reselection to W cell; W2 represents reselection threshold parameter from W cell reselection to G cell; L1 represents reselection from W cell reselection to L cell Threshold parameter; L2 represents a reselection threshold parameter from L cell reselection to G cell.

Specifically, when W1>W2, reselection of L->W->G can be avoided. In other words, reselection from the L cell to the W cell can be avoided, and then the W cell is reselected to the G cell. , you can follow the steps below to determine the reselection threshold parameters:

Step 1: According to the 3GPP TS25.304 protocol, the condition that the high priority W cell reselects to the low priority G cell is: Srxlev _ServingCell <Thresh _{serving, low} , and Srxlev _{nonServingCell, x} >=Thresh _x,low .

Thresh _{serving, low} indicates a threshold parameter that the high priority W cell needs to meet. Thresh _{x, low} indicates the threshold parameter that the low priority G cell needs to meet.

Step 2: According to the 3GPP TS 25.306 protocol, the conditions for reselecting the high priority L cell to the low priority W cell are: Srxlev<Thresh _{Serving, LowP} , and Srxlev>Thresh _{X, LowP} .

Thresh _{Serving, LowP} indicates a threshold parameter that the L cell needs to meet, and Thresh _{X and LowP} indicate _thresholds that the low priority W cell needs to meet.

Step 3: Determine two threshold parameters related to the W cell: Thresh _{serving, low} (ie, W2 in FIG. 9) and Thresh _{X, LowP} (ie, W1 in FIG. 9).

It is assumed that the terminal resides in the L cell. At this time, the W cell signal satisfies cur_RSCP>W1, and the L cell signal is lower than the threshold _Threshing , _LowP , and reselected to the W cell. If W1<W2, then the presence of cur_RSCP<W2 is not excluded. The possibility. In this case, if the G cell signal is greater than the threshold Thresh _x,low , the problem that the W cell is reselected to the G cell again may occur. If the set reselection threshold parameter satisfies W1>W2, then when cur_RSCP>W1, after re-selecting from the L cell to the W cell, it is impossible to have the situation of cur_RSCP>W2, thus eliminating the weight from the W cell. Select the re-selection path of the G cell. In this embodiment, it is assumed that W1 is -80 dbm and W is -85 dbm. Other reasonable thresholds are sufficient as long as the constraints are met.

The threshold parameter shown in FIG. 9 can satisfy the situation that the L/W/G cell can be stably reselected to one network under any signal strength without re-selecting to other networks. In the actual application, in the process of setting the reselection threshold parameter, parameters such as the cell hysteresis value and the cell individual offset need to be considered. In the embodiment of the present invention, for convenience of description, this part is simplified.

Similarly, L1 and L2 values can be given, and L1>L2 is required. In this embodiment, it is assumed that L1 is -80dbm and L2 is -90dbm, and reselection of W->L->G cells can be avoided.

As shown in FIG. 10, the setting of the switching threshold parameter needs to avoid the instability of the switching, which requires consideration of the constraint relationship between the signal threshold parameters of W1, W2, W3, W4, L1, L2, L3, and L4. In FIG. 10, W represents an RSCP threshold of WCDMA, and L represents an RSRP threshold of LTE; specifically, W1, L4 represent handover thresholds that are met when switching from an L cell to a W cell (path1); W2 represents handover from a W cell. a handover threshold that is satisfied when the G cell (path 2) is reached; W3 indicates a handover threshold that is satisfied when the G cell is switched to the W cell (path 5); W4 and L1 indicate that the handover is satisfied when the W cell is switched to the L cell (path 6) The handover threshold; L3 represents the handover threshold that is met when the G cell is switched to the L cell (path3); L2 represents the handover threshold that is met when the L cell is switched to the G cell (path4).

Specifically, when W1>W2, switching of L->W->G can be avoided. In other words, switching from the L cell to the W cell can be avoided, and then the W cell is reselected to the G cell. In this case, Follow these steps to determine the switch threshold parameters:

Step 1: According to the 3GPP TS25.331 protocol, for the 3A event, the conditions for switching from the W cell to the G cell are:

Q _Used ≤T _Used -H _3a /2

M _OtherRAT +CIO _{OtherRAT ≥T OtherRAT} +H _3a /2;

Where Q _used represents the measured value of the current system cell; T _used represents the absolute threshold used by the current system cell; M _otherRat represents the measured value of the target system cell; CIQ _otherRAT represents the individual offset value of the target system cell and the current system cell ; T _otherRAT represents the absolute threshold used by the target system cell; H _3a represents the hysteresis value of the 3A event.

Here, the values of H _3a and CIO _otherRAT need to be considered in the actual design. Here, for convenience of description, it is set to 0, T _used is a threshold parameter that the W cell needs to satisfy, and T _otherRAT is a threshold parameter that the G cell needs to satisfy.

Step 2: According to the 3GPP TS36.331 protocol, for the B2 event, the condition for switching from the L cell to the G cell is:

Mp+Hys<Thresh1

Mn+Ofn-Hys>Thresh2;

Wherein, M _p represents a value of the current measurement system cell; Thresh1 indicates the current absolute value of the door system using the cell 1; M _n represents a measurement value of a target cell system; Ofn: cell individual offset value of the target system and the current system cell; Thresh2: Absolute threshold 2 used by the target system cell; Hys indicates the hysteresis value of the B2 event.

Here, the values of Hys and Ofn need to be considered in the actual design. Here, for convenience of description, it is easy to set to 0, Thresh1 is a threshold parameter that the L cell needs to satisfy, and Thresh2 is a threshold parameter that the W cell needs to satisfy.

Step 3: Determine two threshold parameters related to the W cell: T _used (ie, W2 in FIG. 10) and Thresh2 (W1 in FIG. 10).

It is assumed that the terminal camps on the L cell. At this time, the W cell signal satisfies cur_RSCP>W1, and the L cell signal is lower than Thresh1. After switching to the W cell, if W1<W2, the possibility of having cur_RSCP<W2 is not excluded. In this case, if the G-cell signal is greater than the threshold T _OherRAT , it may happen that the W-cell switches to the G-cell again. If the set handover threshold parameter satisfies W1>W2, then when cur_RSCP>W1, after switching from the L cell to the W cell, it is impossible to have the case of cur_RSCP>W2, thus eliminating the handover from the W cell to the G cell. This switch path. In this embodiment, it is assumed that W1 is -80 dbm and W2 is -85 dbm. Other reasonable thresholds are sufficient as long as the constraints are met.

The threshold parameter shown in FIG. 10 can satisfy the situation that the L/W/G cell can be stably switched to one network under any signal strength without switching to another network again.

Similarly, other threshold constraints can be given:

W3>W4, can avoid the handover of G->W->L cell;

L1>L2 can avoid switching of L->W->G cell;

L3>L4 can avoid the handover of W->L->G cell.
