Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of terminals, and in particular to a method and apparatus for processing inter-system measurement results, a terminal, and a storage medium. BACKGROUND

[0002] With the commercialization of 5G networks (for example, a communication network implementing the 5G NR standard), many mobile phones are also equipped with a 5G network connection function.

[0003] Suppose that a mobile phone initiates a service in a 4G network (for example, a communication network implementing the LTE standard). Under normal circumstances, if the network side detects that there is a 5G network cell in the environment in which the mobile phone is located, the network side will issue an inter-system measurement indication to the mobile phone. After receiving the inter-system measurement indication, the mobile phone will perform measurement on the 5G network cell according to the indication and report an inter-system measurement result (that is, a measurement result for the 5G network cell, which can include information such as the network signal strength of the 5G network cell).

[0004] After the network side receives the inter-system measurement result, the network side controls the redirection of the mobile phone according to specific circumstances. If the network side issues a redirection indication to the mobile phone, the mobile phone will perform redirection, that is, camp on the 5G network cell. If the camping fails, the mobile phone will return to the previous 4G network cell.

[0005] Since the redirection is performed after the release of the 4G network cell (radio resource control release, RRC release) and the scanning and camping of the 5G network cell, the redirection process will affect the transmission of upper-layer service data. During the period from the release of the 4G network cell to the completion of the camping on the 5G network cell, no data transmission is possible, so frequent redirection will seriously affect the transmission of upper-layer data, causing lag and affecting the user experience.

The first network cannot receive the inter-system measurement result, and thus will not issue redirection instruction information to the terminal. The terminal will not register with the abnormal second cell. That is, if the second cell in the environment of the terminal is an abnormal cell, the terminal will not register with the second cell, and the terminal is always in a registered state with the first cell, avoiding frequent redirection of the terminal, better ensuring normal data transmission of the terminal, and improving the use experience.

[0054] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the application, as claimed. BRIEF DESCRIPTION OF DRAWINGS

[0060] The example embodiments will be described in detail herein with reference to the attached drawings. The following description is made with reference to the accompanying drawings in which like reference numerals refer to like elements, and the various embodiments are not limited thereto as described in the specification. The following detailed description is not to be deemed as limiting the scope of the application, as the application is susceptible to alterations and modifications.

[0061] In the related art, when the terminal is in a communication connection state of a 4G network, if the network cell redirection for a 5G network fails, the mobile phone will return to the previous network cell (i.e., the network cell of the 4G network). However, since the environment in which the terminal is located is most likely unchanged, the network cell of the 4G network will again issue inter-system measurement for the network cell for which the registration fails (i.e., the network cell of the 5G network), and the terminal will report the inter-system measurement results to the network side. The network side will most likely instruct the terminal to perform redirection again, and the terminal will most likely fail again. Such a cycle will continue, and if the terminal is not moved out of the current environment, the terminal will frequently perform redirection, which will seriously affect normal data transmission, cause the network of the terminal to be continuously abnormal, and seriously affect the user experience.

[0062] The present disclosure provides a method for processing inter-system measurement results, applied to a terminal (e.g. a mobile phone). In the method, an abnormal cell library is provided in the terminal. If a second cell of a second network is a network cell in the abnormal cell library, in a state where the terminal is registered to a first cell of a first network, after inter-system measurement is performed on the second cell, the terminal is prohibited from reporting the inter-system measurement results to the first cell of the first network. Since the first cell cannot receive the inter-system measurement results, the terminal will not be sent a redirection instruction information, and the terminal will not be registered to the abnormal second cell. That is, if the second cell in the environment where the terminal is located is an abnormal cell, the terminal will not be registered to the second cell. The terminal is always in a registered state with the first cell, avoiding frequent redirection of the terminal, better ensuring normal data transmission of the terminal, and improving the user experience.

[0063] In one example embodiment, a method for processing inter-system measurement results is provided, applied to a terminal. Referring to FIG. 1, Figure 1 The method comprises:

[0064] S110, receiving a measurement instruction for performing inter-system measurement on a second cell from a first cell;

[0065] S120, performing inter-system measurement on the second cell according to the received measurement instruction, and obtaining inter-system measurement results of the second cell;

[0066] S130, determining whether the second cell is a network cell in an abnormal cell library;

[0067] S140, if it is determined that the second cell is a network cell in the abnormal cell library, prohibiting reporting the inter-system measurement results to the first cell.

[0068] In step S110, the first cell belongs to a first network, and the second cell belongs to a second network different from the first network.

[0069] The measurement instruction includes cell information required for measurement.

[0070] For example, the measurement instruction includes a number of the second cell, a frequency point, etc., which can be used to determine a unique identifier of the second cell.

[0071] The first network can be one of a 3G network (e.g. a communication network implementing UMTS standards), a 4G network (e.g. a communication network implementing LTE standards), and a 5G network (e.g. a communication network implementing 5G NR standards), and the second network can also be one of a 3G network, a 4G network, and a 5G network, and the second network is different from the first network.

[0072] It should be noted that, in general, it is considered that the data transmission of the 5G network is superior to that of the 4G network, and the data transmission of the 4G network is superior to that of the 3G network. When the second network is superior to the first network, the first cell of the first network will issue a measurement indication for performing inter-system measurement on the second cell of the second network. The terminal will only receive the above-mentioned measurement indication.

[0073] Example 1,

[0074] The terminal has the capability of 5G network communication, and it is currently in a 4G network communication state, that is, the terminal is registered in a network cell (i.e., a first cell) of a 4G network. In this state, the network side (for example, the 4G network core network) detects that there is one or more (including two) network cells of a 5G network at the location of the terminal. The network side will issue an inter-system measurement indication about a network cell (i.e., a second cell) of a certain 5G network to the terminal based on the 4G network communication state, and the terminal will receive the measurement indication for performing inter-system measurement on the second cell from the first cell.

[0075] In step S120, after the terminal receives the measurement indication, it will perform inter-system measurement on the second cell. The inter-system measurement can include detecting the signal strength, signal stability, and the like of the second cell. Then the inter-system measurement result is obtained. The inter-system measurement result corresponds to the content of the inter-system measurement, which can include the signal strength, signal stability, and the like of the second cell.

[0076] In steps S130 and S140, the abnormal cell library can also be called an abnormal cell list, which can include a network cell that is registered abnormally, that is, a network cell that the terminal cannot normally register.

[0077] When the second cell belongs to the abnormal cell library, that is, the second cell is a network cell in the abnormal cell library, it indicates that the second cell is an abnormal cell. The terminal cannot normally register in the second cell. At this time, even if the terminal has obtained the inter-system measurement result of the second cell through inter-system measurement, the terminal does not report the inter-system measurement result to the first network. The first network will not issue redirection information (the redirection information is used to indicate that the terminal is redirected from a serving cell to another cell) to the terminal. The terminal will not register in the second cell. Therefore, the terminal is always in the first network communication state, avoiding useless data transmission caused by frequent redirection of the terminal, and also avoiding frequent disconnection of the terminal caused by frequent redirection of the terminal, thereby avoiding the terminal from freezing, and improving the user experience.

[0078] When any terminal in the mobile network fails to register a network cell, the terminal uploads the information of the failed network cell to the cloud. The cloud stores the information of the failed network cell (also referred to as an abnormal cell) and forms an abnormal cell library. In addition, the terminal stores the abnormal cells that the terminal has failed to register and forms an abnormal cell library, which is not limited.

[0079] In the method, when the terminal is in the first cell communication state, if the second cell in the environment where the terminal is located is an abnormal cell, the terminal does not register with the second cell. The terminal is always registered with the first cell, that is, the terminal is always in the first cell communication state, which avoids frequent redirection of the terminal, better ensures normal data transmission of the terminal, and improves user experience.

[0080] In an example embodiment, a method for processing inter-system measurement results is provided and applied to a terminal. In the method, after determining that the second cell belongs to the abnormal cell library, the method further includes accumulating the number of times of prohibiting reporting, wherein the number of times of prohibiting reporting refers to the number of times of prohibiting reporting of the inter-system measurement results of the second cell.

[0081] The number of times of prohibiting reporting refers to that each time the second cell is determined to be a network cell of the abnormal cell library, the current number of times of prohibiting reporting is increased by 1.

[0082] Example 1,

[0083] The terminal receives a measurement indication for inter-system measurement of the second cell from the first cell. It is assumed that the number of times of prohibiting reporting of the second cell of the terminal is currently 0. According to the foregoing description, if the terminal determines that the second cell is a network cell in the abnormal cell library, the terminal prohibits reporting of the inter-system measurement results of the second cell. At the same time, the number of times of prohibiting reporting of the second cell is accumulated. That is, the number of times of prohibiting reporting of the second cell is increased by 1, and the updated number of times of prohibiting reporting is 1.

[0084] Example 2,

[0085] The terminal receives a measurement indication for inter-system measurement of the second cell from the first cell. It is assumed that the number of times of prohibiting reporting of the second cell of the terminal is currently 3. If it is determined that the second cell is a network cell in the abnormal cell library, the number of times of prohibiting reporting is updated to 4.

[0086] In the method, the terminal accumulates the number of times of prohibiting reporting of the second cell, which facilitates subsequent judgment of the network condition of the second cell according to the number of times of prohibiting reporting of the second cell, so as to facilitate improvement of the second cell.

[0087] In an example embodiment, a method for processing inter-system measurement results is provided and applied to a terminal. The method further includes:

[0088] S210, if it is determined that the number of prohibited reporting times is greater than or equal to the preset number of times, a first message is generated;

[0089] S220, according to the first message, triggering a location area update, and prohibiting the terminal from registering with the second cell;

[0090] S230, sending the first message to the first network.

[0091] The first message is used to prohibit the terminal from registering with the second cell, that is, to prohibit the terminal from registering with the second cell.

[0092] The first message can be generated by the terminal itself, and after the terminal generates the first message, it is transmitted to the upper layer (such as the NAS layer (non-access layer)) by the bottom layer (such as the RRC layer (radio resource control layer)). Figure 1a

[0093] In this method, the terminal will trigger a location area update according to the first message, and update the second network connection parameter of the terminal (the second network connection parameter is used for the terminal to connect to the second network, that is, the second network connection parameter is used for the terminal to register with the network cell of the second network). The terminal prohibits its own connection capability with the second network, thereby prohibiting its own registration with the network cell of the second network.

[0094] According to an embodiment, the terminal can send a location area update request to the first cell according to the first message. The location area update request includes a terminal capability indication (such as an indication of the terminal's capability to access the network to which the second cell belongs) and other parameters. In an embodiment, the terminal can remove the second network capability related parameter in the location area update request sent by the terminal, that is, inform the first cell that the terminal does not support the capability to register with the cell in the second network. In this way, the terminal can prohibit its own connection capability with the second network, thereby prohibiting its own registration with the network cell of the second network.

[0095] The second network connection parameter can be an N1mode parameter and a DCNR (Dual Connectivity E-UTRAN and NR) parameter. The N1mode parameter is used to indicate whether the terminal supports SA (standalone networking) capability (that is, connection capability with a 5G network in the form of SA). When the N1mode parameter is 0, it indicates that the terminal does not support SA capability; when the N1mode parameter is 1, it indicates that the terminal supports SA capability. The DCNR parameter is used to indicate whether the terminal supports NSA (non-standalone networking) capability (connection capability with a 5G network in the form of NSA). When the DCNR parameter is 0, it indicates that the terminal does not support NSA capability; when the DCNR parameter is 1, it indicates that the terminal supports NSA capability. ​

[0096] Meanwhile, the terminal sends the first message to the first cell, and the first cell knows that the terminal prohibits registration to the second cell, and the first cell will not issue a measurement instruction for the terminal to perform inter-system measurement on the second cell. Thus, the terminal can avoid frequent inter-system measurement on the second cell, and the power consumption of the terminal can be reduced.

[0097] Example 1,

[0098] The preset number of times is 5, and the terminal is currently in a communication state of a 4G network. If the number of times of prohibiting reporting on the second cell (belonging to a 5G network) reaches 5, the terminal triggers to generate a message (i.e., the first message) for removing the connection capability of the 5G network. The terminal can trigger a location area update according to the message. When the location area update is performed, the 5G network connection parameter of the terminal is updated, and the terminal is prohibited from establishing a communication connection capability of the 5G network. That is, the terminal is prohibited from registering to a network cell of the 5G network. The updating of the 5G network connection parameter of the terminal is used to remove the SA capability and NSA capability of the terminal for the 5G network. After the terminal removes the capabilities, the terminal cannot perform a communication connection of the 5G network, and cannot register to a network cell of the 5G network.

[0099] Meanwhile, the terminal sends the message to a core network (for example, a MME in reference Figure 1a The MME refers to a network node, which belongs to a part of the core network, and is responsible for signaling processing. The core network is informed that the terminal prohibits the connection capability of the 5G network, and cannot register to a network cell of the 5G network, and the core network will not issue a measurement instruction for inter-system measurement on a network cell of the 5G network.

[0100] It should be noted that the location area update in the method is similar to the location area update in the prior art. The method focuses on establishing a new mechanism for triggering a location area update (i.e., triggering a location area update based on the first message), and updating the network connection parameter when the location area update is performed, so that the terminal temporarily prohibits the connection capability of the second network (i.e., prohibits registration to a network cell of the second network).

[0101] In the method, when the number of times of prohibiting reporting on the second cell is too large, the registration capability of the terminal for the second cell is removed, and the first network will not instruct the terminal to perform inter-system measurement on the second cell. Not only can the frequent redirection be avoided, but also the terminal can avoid frequent inter-system measurement on the second cell, and the power consumption of the terminal can be reduced.

[0102] In one example embodiment, a method for processing inter-system measurement result is provided, which is applied to a terminal. In the method, after the terminal is prohibited from registering with a second cell, the method further comprises: determining that a preset time period has elapsed, triggering location area update again, and resuming the registration of the terminal with the second cell.

[0103] In the method, a timing module can be started when the terminal is prohibited from registering with the second cell. The timing module is used to time the duration of the prohibition. The preset time period (e.g., 1 hour or 12 hours) can be set in the timing module. After the duration of the prohibition has elapsed, the terminal can generate a second message and trigger location area update again according to the second message to resume the registration of the terminal with the second cell. That is, the ability of the terminal to register with the second cell is resumed.

[0104] Meanwhile, the terminal can also send the second message to the core network of the first network to inform the first cell that the terminal has resumed the connection ability to the second network, and the first cell can resume sending measurement instructions to the terminal for performing inter-system measurement on the network cells of the second network.

[0105] In the method, the second message is similar to the first message. As shown in Figure 1a the second message can also be generated by the terminal itself. After the terminal generates the second message, the second message is transmitted from a lower layer (e.g., RRC layer (Radio Resource Control layer)) to an upper layer (e.g., NAS layer (Non-Access Stratum layer)).

[0106] In the method, the terminal can avoid frequent inter-system measurement and permanently lose the connection ability to the second network. That is, the method can also resume the previously prohibited connection ability (also called registration ability) to ensure that the terminal can continue to use the second network and can continue to register with the network cells of the second network, thereby further improving the user experience.

[0107] In one example embodiment, a method for processing inter-system measurement result is provided, which is applied to a terminal. The method further comprises:

[0108] If a preset condition is met, the abnormal cell library is reset.

[0109] In the method, resetting the abnormal cell library can be clearing the network cells in the abnormal cell library, restoring the abnormal cell library to a factory state (the abnormal cell library has been preset before the terminal is shipped), or deleting the abnormal cell library (the abnormal cell library has not been preset before the terminal is shipped).

[0110] The preset condition can be that the reset period of the abnormal cell is reached, and / or the terminal is restarted.

[0111] For example, the reset period of the abnormal cell is set to 1 month, that is, the abnormal cell library is reset every other month.

[0112] For example, when the terminal restarts, the database of abnormal cells is reset at the same time.

[0113] Of course, meeting the preset conditions can also include other situations. For example, determining that the preset conditions are met may include:

[0114] If the protocol layer prohibits the cell database from being reset, then the preset conditions are determined to be met.

[0115] The "prohibited cell database" refers to a database of network cells that the terminal's radio connectivity protocol layer prohibits it from connecting to. These network cells are those that the terminal explicitly prohibits from registering with.

[0116] Typically, a protocol-layer prohibited cell database is configured in the terminal. This database contains network cells that the network side has explicitly rejected for terminal registration, each with a clearly defined reason for rejection. This database is reset (including updates and / or deletion) according to network protocol requirements. Furthermore, the network cells included in this database are generally different from those in the abnormal cell database, which contains network cells not included in the prohibited cell database and whose registration has been abnormal.

[0117] For example, if the network side explicitly states that the duration for which a cell in the protocol layer prohibits access is 12 hours, then after 12 hours, the protocol layer prohibition cell database can be reset (e.g., cleared), and the abnormal cell database will also be reset to ensure that the two cell databases are reset synchronously.

[0118] For example, each time the terminal restarts (or switches to airplane mode), the protocol layer prohibited cell database is reset. During this reset, the abnormal cell database can also be reset simultaneously to ensure synchronized reset of the two databases. In this method, the abnormal cell database can be reset synchronously with the existing protocol layer prohibited cell database in the terminal, thereby improving the mechanism for synchronously resetting relevant network configuration parameters, reducing power consumption and program complexity, and further enhancing the user experience.

[0119] In one exemplary embodiment, a method for processing measurement results from different systems is provided, applied to a terminal. The method further includes:

[0120] S310. If it is determined that the second cell does not belong to the network cell in the abnormal cell database, then report the inter-system measurement results to the first cell.

[0121] S320, Receive redirection information sent by the first cell;

[0122] S330. Register with the second cell according to the redirection information;

[0123] S340, if it is determined that the registration to the second cell fails, the second cell is added to the abnormal cell library.

[0124] In step S310, if it is determined that the second cell does not belong to the network cell in the abnormal cell library, it means that the second cell is not identified as an abnormal cell. The terminal can report the inter-system measurement result to the first cell, so that the first cell performs the next step of processing according to the inter-system measurement result.

[0125] In step S320, the redirection information is sent by the first cell in response to the inter-system measurement result. That is, after the first cell receives the inter-system measurement result, it generates corresponding redirection information according to the inter-system measurement result, and then sends it to the terminal. The terminal can receive the redirection information.

[0126] In step S330, after the terminal receives the redirection information, it registers with the second cell according to the redirection information. In this process, the connection of the first network needs to be disconnected (that is, the terminal is no longer registered with the first cell). Therefore, during the redirection process, the terminal is actually in a disconnected state and cannot normally perform data transmission.

[0127] In step S340, if it is determined that the registration to the second cell fails, the terminal returns to the registration state with the first cell. That is, the terminal returns to the communication connection state of the first network, and realizes data transmission through the first network.

[0128] At the same time, the terminal can also add the second cell to the abnormal cell library. If the inter-system measurement is performed again for the second cell, since the second cell has been added to the abnormal cell library, the terminal will determine that the second cell belongs to the abnormal cell library. The terminal can prohibit the reporting of the inter-system measurement result of the second cell to the first cell. The first cell no longer sends redirection information to the terminal. The terminal no longer registers with the second cell. This method avoids frequent redirection of the terminal, ensures normal data transmission of the terminal, and improves the user experience.

[0129] It should be noted that in the method, the abnormal cell library can be pre-set in the terminal before the terminal is shipped, or can be set by the user later, or can be established after the first redirection fails.

[0130] Example 1,

[0131] The abnormal cell library is pre-set before the terminal is shipped. The number of network cells in the abnormal cell library is 0, that is, the abnormal cell library is empty and no abnormal cell is set. When a network cell that fails to redirect appears, the network cell can be added to the above abnormal cell library. In turn, the network cells in the abnormal cell library are gradually added.

[0132] Example 2,

[0133] After the user purchases the terminal, the user can establish an abnormal cell library by himself during the use. The abnormal cell library can be an empty library without any network cell added. It can be understood that the user can also add the network cell which he considers as having bad signal to the abnormal cell library. When the network cell which causes redirection failure appears, the network cell can be added to the abnormal cell library. In turn, the network cells in the abnormal cell library are gradually added.

[0134] Example 3,

[0135] After the terminal first causes redirection failure, the abnormal cell library can be established and the network cell which causes redirection failure can be added to the abnormal cell library. At this time, the abnormal cell library only has the network cell which causes redirection failure. When the new network cell which causes redirection failure appears again, the network cell can be added to the abnormal cell library. In turn, the network cells in the abnormal cell library are gradually added.

[0136] In the method, if it is determined that the second cell is not the cell in the abnormal cell library, the inter-system measurement result is reported to the first network normally. After the network side receives the inter-system measurement result, if the requirement is met, the network side can send the redirection information to the terminal according to the inter-system measurement result. After the terminal receives the redirection information, the terminal can perform redirection, that is, registration to the second cell.

[0137] When the terminal causes redirection failure, the network cell which causes registration failure can be added to the abnormal cell library, so as to avoid the terminal frequently performing redirection to the network cell, thereby better avoiding frequent flow interruption (i.e. network connection to the terminal) and ensuring normal data transmission and improving user experience.

[0138] In an example embodiment, a method for processing inter-system measurement result is provided, which is applied to the terminal and the device (e.g. base station) of the network side. Referring to Figure 1a The UE in the figure refers to the user equipment, that is, the terminal in the present application. The eNB (eNode-B) refers to the base station. The MME refers to the network node, which belongs to the part of the core network and is responsible for the signaling processing part. The bidirectional arrow in the figure indicates that there is interaction between the two, that is, there is information transmission. Among them, the NAS refers to the non-access layer, the RRC refers to the radio resource control protocol layer, the PDCP is the abbreviation of packet data convergence protocol; the RLC refers to the radio link control sublayer; the MAC refers to the medium access control layer; and the PHY refers to the port physical layer. The communication between the above layers can be completed through message passing.

[0139] Referring to Figure 1aNAS belongs to non-access layer and does not pass through the eNB; RRC, PDCP, RLC, MAC, and PHY form the access layer. Among them, RRC is responsible for air interface connection and belongs to the connection layer, which only exists in the control plane; PDCP segments and links the data from the upper layer, performs header compression and encryption, and if it is VoLTE, it also compresses the voice packet; RLC is only in the data plane and has the function of wireless link control, mainly ARQ error correction; MAC mainly has the functions of HARQ and scheduling.

[0140] In the method, it is assumed that the terminal (i.e., UE in the figure) is currently in a communication connection state of the 4G network, and the terminal is registered in a first cell of the 4G network, where the first cell can refer to an area covered by a signal of a base station of the 4G network. That is, the terminal is in communication connection with the above-mentioned base station (i.e., eNB in the figure) of the 4G network.

[0141] The first cell sends a measurement indication for performing inter-system measurement on a second cell (belonging to the 5G network, and for the same reason, the second cell can refer to an area covered by a signal of a base station of the 5G network) to the terminal for the first time. In fact, the base station (i.e., eNB in the figure) of the 4G network sends the measurement indication to the terminal. Figure 1a

[0142] After receiving the above-mentioned measurement indication, the terminal can perform inter-system measurement on the second cell according to the measurement indication and obtain an inter-system measurement result.

[0143] After the terminal obtains the inter-system measurement result, the terminal can report the first inter-system measurement result to the first cell (i.e., report the inter-system measurement result to the base station forming the first cell). The first cell receives the inter-system measurement result and, according to the inter-system measurement result, sends redirection information for the second cell to the terminal. In fact, the terminal reports the inter-system measurement result to the base station of the 4G network, and then the base station sends the redirection information to the terminal based on the inter-system measurement result.

[0144] The terminal receives the redirection information and, according to the redirection information, registers with the second cell (i.e., establishes a communication connection with the base station forming the second cell). If it is determined that the registration with the second cell fails, an empty abnormal cell library is established, and the second cell is added to the abnormal cell library.

[0145] When the first cell sends a measurement indication for performing inter-system measurement on the second cell to the terminal again. The terminal receives the measurement indication and performs inter-system measurement on the second cell again according to the measurement indication, and obtains an inter-system measurement result.

[0146] In addition, since the terminal can determine that the second cell belongs to the network cell in the abnormal cell library, the terminal can prohibit reporting the inter-system measurement result this time to the first cell, and the number of times of prohibiting reporting is accumulated to 1. ​

[0147] By analogy, until the number of reporting prohibitions accumulates to a preset number (for example, 5 times).

[0148] The RRC layer of the terminal can generate the first information and transmit the first information to the NAS layer of the terminal. The NAS layer triggers a location area update according to the first information, and prohibits the terminal from registering with the second cell.

[0149] Meanwhile, the terminal reports the first information to a network node (namely, an MME in the 4G network) of the 4G network, and informs the 4G network that the terminal has been prohibited from registering with the second cell (for example, removes the connection capability of the terminal with the 5G network). The base station of the 4G network no longer issues a measurement instruction for the terminal to perform inter-system measurement on the second cell. Figure 1a

[0150] After a preset time period (for example, 24 hours), the RRC layer of the terminal can generate the second information and transmit the second information to the NAS layer of the terminal. The NAS layer triggers a location area update again according to the second information, and restores the terminal to register with the second cell.

[0151] Meanwhile, the terminal reports the second information to the network node of the 4G network, and informs the base station of the 4G network that the terminal has restored to register with the second cell (that is, the terminal has restored the connection capability with the 5G network that has been removed before), and the first cell can continue to issue a measurement instruction for the terminal to perform inter-system measurement on the network cell of the 5G network.

[0152] The method can avoid frequent redirection of the terminal. Especially in the case where the location of the terminal does not change, the redirection of the terminal to the same network cell and the inter-system measurement on the same network cell can be effectively avoided, thereby reducing the power consumption of the terminal, avoiding frequent flow interruption of the terminal, and improving the user experience.
