Method for terminal to connect to network, and terminal

Abstract

The present application provides a method for a terminal to connect to a network, and a terminal. The method can be applied to the terminal. Under the condition that a terminal suppresses a first-standard network and camps on a second-standard network, when the signal quality of the second-standard network does not satisfy a first quality requirement, the terminal can be triggered to release the suppression of the first-standard network, wherein a first standard has higher priority than a second standard; and the signal quality of the second-standard network not satisfying the first quality requirement can indicate that a second-standard network environment has deteriorated. Therefore, when the second-standard network environment deteriorates, the terminal can release the suppression of the first-standard network in time, thereby avoiding the impact on service usage due to prolonged camping on the inferior second-standard network, and facilitating a rapid handover to the superior first-standard network, thus optimizing the connection between the terminal and the network.

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 11, 2024, with application number 202410045408.4 and application name “A method and terminal for connecting a terminal to a network”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of terminal technology, and in particular to a method for connecting a terminal to a network and a terminal. Background Art

[0003] Standalone (SA) networking is a network mode of the fifth generation (5G) mobile communications. SA networks refer to new radio (NR) networks within SA mode. Currently, due to the limited SA network coverage in existing networks, devices may encounter poor SA network conditions when resident on SA networks. In such conditions, these conditions may trigger devices to suppress SA networks. Summary of the Invention

[0004] The embodiments of the present application provide a method for connecting a terminal to a network and a terminal, which can optimize the connection between the terminal and the network.

[0005] In a first aspect, an embodiment of the present application provides a method for connecting a terminal to a network, applied to a terminal, comprising: when the terminal suppresses a network of a first standard and resides on a network of a second standard, the terminal detects the signal quality of the network of the second standard, where the signal quality of the first standard is higher than that of the second standard; when a first condition is met, the terminal releases the suppression of the network of the first standard, where the first condition includes: the signal quality of the network of the second standard does not meet a first quality requirement;

[0006] The terminal suppressing the first-standard network includes one or more of the following:

[0007] The terminal lowers the priority of accessing the network of the first standard;

[0008] The terminal disables the first-standard network;

[0009] The terminal disables the first cell;

[0010] The terminal disables the first standard network of the first PLMN; or

[0011] The terminal disables the first cell of the first PLMN;

[0012] The first cell is a network cell of the first standard where the terminal resides before residing in the network of the second standard, and the first cell does not meet the service needs of the terminal before being disabled; the first PLMN is the PLMN corresponding to the network of the first standard where the terminal resides before residing in the network of the second standard.

[0013] Through the above method, when the terminal suppresses the network of the first standard and resides on the network of the second standard, it can be determined whether to trigger the terminal to release the suppression of the network of the first standard based on whether the signal quality of the network of the second standard meets the first quality requirement. Specifically, the terminal can be triggered to release the suppression of the network of the first standard when the signal quality of the network of the second standard does not meet the first quality requirement, wherein the signal quality of the network of the second standard does not meet the first quality requirement, which can indicate that the network environment of the second standard has deteriorated. In this way, when the network environment of the second standard deteriorates, the terminal can promptly release the suppression of the network of the first standard, thereby avoiding the continuous residence in the poor network environment of the second standard affecting the use of services, and then facilitating a quick switch to a better network environment of the first standard.

[0014] With reference to the first aspect, in a possible implementation, the terminal unsuppressing the network of the first standard includes one or more of the following:

[0015] The terminal increases the priority of accessing the network of the first standard;

[0016] The terminal cancels the prohibition of the first-standard network;

[0017] The terminal cancels the disabling of the first cell;

[0018] The terminal cancels the prohibition of the first-standard network of the first PLMN; or

[0019] The terminal cancels disabling of the first cell of the first PLMN;

[0020] Through the above implementation, the terminal can suppress and release the first-standard network at different levels (such as network level, cell level and PLMN level), which is conducive to adapting to different application scenarios or network connection requirements.

[0021] In combination with the first aspect, in a possible implementation, when the terminal is in a screen-off state, the first condition also includes: the interval between the current time and the time when the terminal last released the suppression of the first-standard network is greater than or equal to a first duration.

[0022] Through the above implementation, when the terminal is in the screen-off state, a minimum time interval between two adjacent unsuppression of the first-standard network is set, so that frequent network switching can be avoided, which is beneficial to reducing terminal power consumption.

[0023] In combination with the first aspect, in a possible implementation method, when the number of times the terminal last lifted the suppression of the first-standard network is less than the first number, the first duration is a first value; or, when the number of times the terminal last lifted the suppression of the first-standard network is greater than or equal to the first number, the first duration is a second value; wherein, the first value is less than the second value.

[0024] Through the above implementation method, the minimum time interval between two adjacent times that the terminal lifts the suppression of the first-standard network is related to the number of times the terminal has performed the suppression (that is, the number of times corresponding to the last time the suppression of the first-standard network was lifted). Before the number of times the terminal has performed the suppression reaches the first number, the first duration can take a smaller value. When the number of times the terminal has performed the suppression reaches / after the first number, the first duration can take a larger value, which can further avoid frequent network switching.

[0025] With reference to the first aspect, in a possible implementation, before the terminal suppresses the network of the first standard, the method further includes:

[0026] In the case where the terminal resides on a network of the first standard, when a second condition is met, the terminal suppresses the network of the first standard, where the second condition includes: signal quality of the network of the first standard does not meet a second quality requirement.

[0027] Through the above implementation, when the terminal resides on a first-standard network, it can be determined whether to trigger the terminal to suppress the first-standard network based on whether the signal quality of the first-standard network meets the second quality requirement. Specifically, the terminal can be triggered to suppress the first-standard network when the signal quality of the first-standard network does not meet the second quality requirement, wherein the failure of the signal quality of the first-standard network to meet the second quality requirement can indicate that the first-standard network environment has deteriorated. In this way, the terminal can be triggered to suppress the first-standard network when the first-standard network environment deteriorates, thereby preventing the terminal from continuously residing in a poor first-standard network environment and affecting service use.

[0028] With reference to the first aspect, in a possible implementation, when the terminal suppresses the network of the first standard and resides on the network of the second standard, the method further includes:

[0029] The terminal performs neighboring cell measurement;

[0030] The first condition also includes: the terminal measures a network neighboring cell of the first standard, and the signal quality of the network neighboring cell of the first standard meets a third quality requirement.

[0031] Through the above implementation, when the network environment of the second standard where the terminal resides deteriorates and the terminal detects a neighboring area of ​​the first standard network, it can be combined with whether the signal quality of the neighboring area of ​​the first standard network meets the third quality requirement to determine whether to trigger the terminal to release the suppression of the first standard network. Specifically, when the signal quality of the neighboring area of ​​the first standard network meets the third quality requirement, the terminal can be triggered to release the suppression of the first standard network, wherein the signal quality of the neighboring area of ​​the first standard network meets the third quality requirement, which can indicate that the network environment of the first standard is better. In this way, when the network environment of the second standard where the terminal resides deteriorates and the network environment of the first standard is better, the terminal can promptly release the suppression of the first standard network, thereby avoiding the impact of continued residence in the poor second standard network environment on business use, and then facilitating a quick switch to a better first standard network environment.

[0032] With reference to the first aspect, in one possible implementation, the first quality requirement includes a first quality threshold; and the signal quality of the second-standard network does not meet the first quality requirement, including:

[0033] The duration during which the signal quality of the second-standard network is less than the first quality threshold is greater than or equal to a second duration.

[0034] Through the above implementation method, it is possible to judge whether the signal quality of the second-standard network meets the first quality requirement based on the relationship between the duration that the signal quality of the second-standard network is less than the first quality threshold and the second duration. Specifically, when the duration is greater than or equal to the second duration, it is determined that the signal quality of the second-standard network does not meet the first quality requirement, which helps to improve the accuracy of the judgment.

[0035] In combination with the first aspect, in a possible implementation, when the terminal is in a call state, the first quality threshold is a third value; or, when the terminal is in a non-call state, the first quality threshold is a fourth value; wherein the third value is greater than the fourth value.

[0036] Through the above implementation, the first quality threshold when the terminal is in a call state can be greater than the first quality threshold when the terminal is in a non-call state, which helps to ensure the signal quality of the terminal in the call state.

[0037] With reference to the first aspect, in one possible implementation, the second quality requirement includes a second quality threshold and / or a freeze duration threshold; and the signal quality of the first-standard network does not meet the second quality requirement, including:

[0038] The duration for which the signal quality of the network of the first standard is less than the second quality threshold is greater than or equal to a third duration;

[0039] And / or, the freeze duration of the terminal in the first network standard is greater than or equal to the freeze duration threshold.

[0040] Through the above implementation, it is possible to determine whether the signal quality of the first-standard network meets the second quality requirement based on the relationship between the duration of time the signal quality of the first-standard network is less than the second quality threshold and the third duration. Specifically, when the duration is greater than or equal to the third duration, it is determined that the signal quality of the first-standard network does not meet the second quality requirement, which helps improve the accuracy of the judgment. It is also possible to determine whether the signal quality of the first-standard network meets the second quality requirement based on the relationship between the duration of the terminal's freeze in the first-standard network and the freeze duration threshold. Specifically, when the freeze duration is greater than the freeze duration threshold, it is determined that the signal quality of the first-standard network does not meet the second quality requirement, which helps improve the accuracy of the judgment.

[0041] With reference to the first aspect, in a possible implementation manner, the second quality threshold is smaller than the first quality threshold, and the third duration is smaller than the second duration.

[0042] Through the above implementation method, the second quality threshold and the third time duration used when judging whether the signal quality of the first-standard network does not meet the quality requirements can be smaller than the first quality threshold and the second time duration used when judging whether the signal quality of the second-standard network meets the quality requirements. In this way, the tolerance for the first-standard network (i.e., the network with a higher standard) is higher, which is conducive to staying in the network with a higher standard as much as possible.

[0043] With reference to the first aspect, in one possible implementation, the third quality requirement includes a third quality threshold; and the signal quality of the first-standard network neighboring cell meets the third quality requirement, including:

[0044] The duration during which the signal quality of the neighboring cell of the first-standard network is greater than or equal to the third quality threshold is greater than or equal to a fourth duration.

[0045] Through the above implementation method, whether the signal quality of the network neighboring area of ​​the first standard meets the third quality requirement can be judged based on the relationship between the duration that the signal quality of the network neighboring area of ​​the first standard is greater than or equal to the third quality threshold and the fourth duration. Specifically, when the duration is greater than or equal to the fourth duration, it can be determined that the signal quality of the network neighboring area of ​​the first standard meets the third quality requirement, which helps to improve the accuracy of the judgment.

[0046] With reference to the first aspect, in a possible implementation manner, the third quality threshold is less than or equal to the second quality threshold, and the fourth duration is less than or equal to the third duration.

[0047] Through the above implementation method, the third quality threshold and the fourth time length used when judging whether the signal quality of the first-standard network meets the conditions for lifting the suppression can be smaller than the second quality threshold and the third time length used when judging whether the signal quality of the first-standard network meets the conditions for suppression. This is conducive to switching back to the first-standard network as soon as possible.

[0048] With reference to the first aspect, in a possible implementation, the signal quality includes: reference signal received power RSRP, and / or signal to interference plus noise ratio SINR.

[0049] Through the above implementation, both the reference signal received power RSRP and the signal to interference plus noise ratio SINR can more accurately reflect the signal quality, so RSRP and / or SINR can be used to more accurately determine whether the signal quality of the network meets the corresponding quality requirements.

[0050] With reference to the first aspect, in a possible implementation, the terminal includes an AP and a modem, and the modem includes a first interface for unsuppressing a network of a first standard;

[0051] When the first condition is met, the terminal unsuppresses the network of the first standard, including:

[0052] When the AP or the Modem determines that the first condition is met, the AP calls the first interface to release the suppression of the first-standard network; or

[0053] When the AP or the Modem determines that the first condition is met, the Modem releases the suppression of the network of the first standard.

[0054] Through the above implementation, the AP can determine whether the first condition is met, or the modem can determine whether the first condition is met. The AP can call the first interface to unsuppress the first-standard network, or the modem can unsuppress the first-standard network (the modem can trigger the unsuppression of the first-standard network by itself, or the modem can unsuppress the first-standard network under the triggering of the AP).

[0055] With reference to the first aspect, in a possible implementation, the terminal includes an AP and a modem, and the modem includes a second interface for suppressing a network of the first standard;

[0056] When the second condition is met, the terminal suppresses the network of the first standard, including:

[0057] When the AP or the Modem determines that the second condition is met, the AP calls the second interface to suppress the first-standard network; or

[0058] When the AP or the Modem determines that the second condition is met, the Modem suppresses the network of the first standard.

[0059] Through the above implementation, the AP can determine whether the second condition is met, or the modem can determine whether the second condition is met. The AP can call the second interface to suppress the first-standard network, or the modem can suppress the first-standard network (the modem can trigger the suppression of the first-standard network by itself, or the modem can suppress the first-standard network under the triggering of the AP).

[0060] With reference to the first aspect, in a possible implementation manner, the network of the first standard is an SA network, and the network of the second standard is an LTE network.

[0061] In a second aspect, the present application provides a terminal comprising one or more processors and one or more memories; wherein the one or more memories are coupled to the one or more processors, and the one or more memories are used to store computer programs or instructions. When the one or more processors execute the computer programs or instructions, the terminal executes the method described in the first aspect and any possible implementation method of the first aspect.

[0062] In a third aspect, the present application provides a chip system, which is applied to a terminal and includes one or more processors. When the one or more processors execute computer programs or instructions, the terminal executes the method described in the first aspect and any possible implementation of the first aspect. The chip system can be a modem or a system on chip (SoC) that integrates an AP and a modem.

[0063] In a fourth aspect, the present application provides a computer-readable storage medium, which stores a computer program or instruction. When the computer program or instruction runs on a terminal, the terminal executes the method described in the first aspect and any possible implementation method of the first aspect.

[0064] In a fifth aspect, the present application provides a computer program product, which includes a computer program or instructions. When the computer program or instructions are run on a terminal, the terminal executes the method described in the first aspect and any possible implementation method of the first aspect.

[0065] It is understandable that the terminal provided in the second aspect, the chip system provided in the third aspect, the computer storage medium provided in the fourth aspect, and the computer program product provided in the fifth aspect are all used to execute the method provided in this application. Therefore, the beneficial effects brought about by the second to fifth aspects can be referred to the description of the beneficial effects in the first aspect and will not be repeated here.

[0071] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0072] In this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0073] The terms "first," "second," and the like in this application are used to distinguish between different objects, rather than to describe a specific order, and "first," "second," and the like do not necessarily define differences. In addition, the terms "comprise," "include," and "have," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to the process, method, product, or device.

[0074] The “embodiment” mentioned in this application means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It can be understood explicitly and implicitly by those skilled in the art that in the various embodiments of the present application, unless otherwise specified and there is a logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form a new embodiment according to their inherent logical relationship.

[0075] It should be understood that in this application, "at least one" means one or more, and "more than one" means two or more. "And / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0076] In this application, the term “when” may be interpreted to mean “if” or “after” or “in response to determining that” or “in response to detecting that”. Similarly, the phrases “upon determining that” or “if (stated condition or event) is detected” may be interpreted to mean “if it is determined that” or “in response to determining that” or “upon detecting (stated condition or event)” or “in response to detecting (stated condition or event)”.

[0077] Standalone (SA) networking is a network mode of the fifth generation (5G) mobile communications. SA networks refer to new radio (NR) networks within SA mode. Currently, due to the limited SA network coverage in existing networks, devices may encounter poor SA network conditions when resident on SA networks. In such conditions, these conditions may trigger devices to suppress SA networks.

[0078] When a terminal suppresses SA, it may reside on a new network, such as a Long Term Evolution (LTE) network. However, the LTE network may have a poor network environment, and because the terminal suppresses SA, it may not be able to return to the original SA network in a timely manner, which may affect the terminal's use of services such as calls and data transmission.

[0079] In view of this, an embodiment of the present application provides a method and a terminal for connecting a terminal to a network, which can optimize the connection between the terminal and the network. For example, when the terminal suppresses the SA network and resides in the LTE network, the SA network can be promptly unsuppressed when it is detected that the LTE network environment has deteriorated, thereby facilitating timely avoidance of the current poor network environment and switching to a better network environment.

[0080] The following introduces the application scenarios of the embodiments of the present application.

[0081] Please refer to Figure 1, which is a schematic diagram of an application scenario provided by an embodiment of the present application. The application scenario involves a terminal 11, a first network device 12, and a second network device 13. The first network device 12 is a service device (e.g., a base station) corresponding to a network of a first standard, and the second network device 13 is a service device (e.g., a base station) corresponding to a network of a second standard, where the first standard is different from the second standard. For example, the first standard is higher than the second standard.

[0082] The terminal 11 can communicate with the first network device 12 to connect to (access or reside in) a network of the first standard. The terminal 11 can also communicate with the second network device 13 to connect to (access or reside in) a network of the second standard.

[0083] The following describes a method for connecting a terminal to a network provided in an embodiment of the present application.

[0084] The method for connecting a terminal to a network is applied to a terminal, and the method for connecting a terminal to a network may include but is not limited to the following steps 1 and 2.

[0085] Step 1: When the terminal suppresses the network of the first standard and resides on the network of the second standard, the terminal detects the signal quality of the network of the second standard, and the signal quality of the first standard is higher than that of the second standard.

[0086] In some possible embodiments, the first standard network is an SA network, and the second standard network is an LTE network. It should be understood that the first standard network and the second standard network can also be other networks, as long as the first standard is higher than the second standard.

[0087] The terminal suppressing the first-standard network can be understood as the terminal suppressing the use of the first-standard network. For example, when a problem occurs in the first-standard network where the terminal resides (for example, the network environment deteriorates), the terminal may be triggered to suppress the first-standard network.

[0088] In one possible implementation, a terminal may be configured with a suppression function for suppressing the first-standard network. When the suppression function is enabled, the terminal suppresses the first-standard network. When the suppression function is disabled, the terminal releases (or cancels) the suppression of the first-standard network, i.e., the terminal does not suppress the use of the first-standard network.

[0089] For example, a terminal may initially reside on a network of the first standard. When the network environment of the first standard deteriorates and cannot meet the terminal's service needs, the terminal may enable a suppression function for suppressing the first standard network, thereby suppressing the terminal's use of the first standard network. Subsequently, the terminal may leave the first standard network and reside on a second standard network. After residing on the second standard network, the terminal may detect the second standard network to obtain the signal quality of the second standard network.

[0090] In some possible embodiments, the terminal suppresses the network of the first standard, which may specifically be that the terminal lowers the priority of accessing the network of the first standard.

[0091] For example, if the terminal originally has the highest priority for accessing a network of the first standard, then the terminal will prioritize cells in the network of the first standard during cell selection or cell reselection. However, if the terminal lowers the priority for accessing a network of the first standard, the terminal will no longer prioritize cells in the network of the first standard during cell selection or cell reselection.

[0092] In some other possible embodiments, the terminal suppresses the network of the first standard, specifically, the terminal disables the network of the first standard.

[0093] The terminal disabling the first-standard network means that the terminal is prohibited from accessing the first-standard network. Accordingly, the terminal will not select a first-standard network cell when performing cell selection or cell reselection.

[0094] In one possible scenario, the terminal may specifically prohibit the terminal from accessing the network of the first standard, but not prohibiting the terminal from measuring the network of the first standard. In other words, the terminal can measure the network cell of the first standard, but will not access the network cell of the first standard even if the network cell of the first standard meets the corresponding conditions.

[0095] In another possible case, the terminal disabling the first standard network may specifically prohibit the terminal from accessing the first standard network and prohibiting measurement of the first standard network. In other words, the terminal will not access the first standard network cell and will not measure the first standard network cell.

[0096] In some other possible embodiments, the terminal suppresses the network of the first standard, specifically, the terminal disables the first cell.

[0097] The first cell refers to the cell of the first-standard network where the terminal resides before residing on the second-standard network, that is, a cell within the first-standard network where the terminal resides. A terminal disabling the first cell means that the terminal is prohibited from accessing the first cell. This can also be understood as the terminal adding the first cell as a black cell. Accordingly, the terminal will not select the first cell during cell selection or cell reselection. It should be understood that the terminal does not need to disable other cells within the first-standard network. In other words, the terminal can select other cells within the first-standard network during cell selection or cell reselection.

[0098] In one possible case, the terminal disabling the first cell may specifically prohibit the terminal from accessing the first cell but not prohibiting the terminal from measuring the first cell. In other words, the terminal can measure the first cell, but will not access the first cell even if the first cell meets corresponding conditions.

[0099] In another possible case, the terminal disabling the first cell may specifically prohibit the terminal from accessing the first cell and prohibiting the terminal from measuring the first cell. In other words, the terminal will not access the first cell and will not measure the first cell.

[0100] In some further possible embodiments, the terminal suppresses the network of the first standard, specifically, the terminal disables the network of the first standard of the first PLMN.

[0101] The full name of PLMN is public land mobile network. The first PLMN refers to the PLMN corresponding to the first-standard network where the terminal resides before residing on the second-standard network.

[0102] The terminal disabling the first-standard network of the first PLMN means that the terminal is prohibited from accessing the first-standard network of the first PLMN. Accordingly, the terminal will not select the first-standard network cell of the first PLMN when performing cell selection or cell reselection.

[0103] In one possible scenario, the terminal disabling the first-standard network of the first PLMN may specifically prohibit the terminal from accessing the first-standard network of the first PLMN, but does not prohibit measuring the first-standard network of the first PLMN. In other words, the terminal can measure the first-standard network cell of the first PLMN, but will not access the first-standard network cell of the first PLMN even if the first-standard network cell of the first PLMN meets corresponding conditions.

[0104] In another possible scenario, the terminal disabling the first-standard network of the first PLMN may specifically prohibit the terminal from accessing the first-standard network of the first PLMN and prohibiting the terminal from measuring the first-standard network of the first PLMN. In other words, the terminal will not access the first-standard network cell of the first PLMN and will not measure the first-standard network cell of the first PLMN.

[0105] In some other possible embodiments, the terminal suppresses the network of the first standard, specifically, the terminal disables the first cell of the first PLMN.

[0106] The first PLMN refers to the PLMN corresponding to the first-standard network where the terminal resides before residing in the second-standard network. The first cell of the first PLMN refers to the first-standard network cell where the terminal resides before residing in the second-standard network, that is, a cell under the first-standard network of the first PLMN where the terminal resides.

[0107] The terminal disabling the first cell of the first PLMN means that the terminal prohibits access to the first cell of the first PLMN. It can also be understood that the terminal adds the first cell of the first PLMN as a black cell. Accordingly, the terminal will not select the first cell of the first PLMN during cell selection or cell reselection. It should be understood that the terminal may not disable other cells under the first-standard network of the first PLMN. In other words, the terminal may select other cells under the first-standard network of the first PLMN during cell selection or cell reselection.

[0108] In one possible scenario, the terminal disabling the first cell of the first PLMN may specifically prohibit the terminal from accessing the first cell of the first PLMN, but does not prohibit the terminal from measuring the first cell of the first PLMN. In other words, the terminal can measure the first cell of the first PLMN, but will not access the first cell of the first PLMN even if the first cell of the first PLMN meets corresponding conditions.

[0109] In another possible case, the terminal disabling the first cell of the first PLMN may specifically prohibit the terminal from accessing the first cell of the first PLMN and prohibiting the terminal from measuring the first cell of the first PLMN. In other words, the terminal will not access the first cell of the first PLMN and will not measure the first cell of the first PLMN.

[0110] Through the above embodiment, the terminal can suppress the first-standard network at different levels (such as network level, cell level and PLMN level), which is conducive to adapting to different application scenarios or suppression requirements.

[0111] Step 2: When a first condition is met, the terminal unsuppresses the network of the first standard. The first condition includes: the signal quality of the network of the second standard does not meet the first quality requirement.

[0112] The terminal's lifting of the suppression of the first-standard network can be understood as the terminal no longer suppressing the use of the first-standard network. Exemplarily, the terminal's lifting of the suppression of the first-standard network can mean that the terminal increases the priority of accessing the first-standard network, or restores the originally set priority of accessing the first-standard network. It can also mean that the terminal cancels the prohibition of accessing the first-standard network or the first-standard network of the first PLMN. It can also mean that the terminal cancels the prohibition of accessing the first cell or the first cell of the first PLMN, which can also be understood as removing the first cell or the first cell of the first PLMN from the black cell list.

[0113] The first condition can be understood as a condition that triggers the terminal to release the suppression of the first-standard network, or it can be understood as a condition that determines that the second-standard network environment where the terminal resides has deteriorated. In other words, when the second-standard network environment where the terminal resides deteriorates, the terminal can be triggered to release the suppression of the first-standard network.

[0114] Specifically, after the terminal resides on the second-standard network, it can detect the second-standard network and obtain the signal quality of the second-standard network. For example, it can monitor the environmental information of the physical layer and link layer and the interaction with the network through a modem to obtain the signal quality of the second-standard network. Then, based on whether the signal quality of the second-standard network meets the first quality requirement, it is determined whether to trigger the terminal to release the suppression of the first-standard network.

[0115] In one possible scenario, the signal quality of the second-standard network does not meet the first quality requirement. In this case, the signal quality of the second-standard network can be considered poor, and the second-standard network environment can be considered poor, which can trigger the terminal to release the suppression of the first-standard network.

[0116] In another possible case, the signal quality of the second-standard network meets the first quality requirement. In this case, the signal quality of the second-standard network can be considered good, and the second-standard network environment can be considered good, so the terminal will not be triggered to release the suppression of the first-standard network.

[0117] In some possible embodiments, a terminal includes an application processor (AP) and a modem, wherein the modem includes a first interface for unblocking a network of a first standard. The first interface may be a software interface, and illustratively, the first interface may be a function or command for unblocking a network of the first standard.

[0118] When the first condition is met, the terminal unblocks the first-standard network. Specifically, when the AP or the modem determines that the first condition is met, the AP calls the first interface to unblock the first-standard network. Alternatively, when the AP or the modem determines that the first condition is met, the modem unblocks the first-standard network.

[0119] In some implementations, the AP can determine whether the first condition is met, and then when the AP determines that the first condition is met, the AP calls the first interface of the modem to unsuppress the network of the first standard; the modem can also determine whether the first condition is met, and then when the modem determines that the first condition is met, the modem directly unsuppresses the network of the first standard.

[0120] In some possible embodiments, when the terminal is in a screen-off state, the first condition further includes: an interval between the current time and the time when the terminal last released suppression of the first-standard network is greater than or equal to a first duration.

[0121] Among them, the first duration can be understood as the minimum time interval between two adjacent unsuppressions of the first-standard network when the terminal is in the screen-off state. The current time refers to the time when the terminal is currently triggered to unsuppress the first-standard network. If the interval between the current time and the time when the terminal last unsuppressed the first-standard network is greater than or equal to the first duration, the terminal can unsuppress the first-standard network. If the interval between the current time and the time when the terminal last unsuppressed the first-standard network is less than the first duration, the terminal may not unsuppress the first-standard network. It should be noted that the first duration can be preconfigured or predefined, and the embodiments of the present application do not limit it.

[0122] Through the above embodiment, when the terminal is in the screen-off state, a minimum time interval between two adjacent unsuppression of the first-standard network is set, so that frequent network switching can be avoided, thereby helping to reduce terminal power consumption.

[0123] Optionally, when the terminal is in the bright screen state, a minimum time interval between two adjacent unsuppressions of the first-standard network may be set (for example, as the fifth duration). The fifth duration may be preconfigured or predefined, and is not limited in the embodiments of the present application. Optionally, the fifth duration is less than the first duration, so that the terminal can respond to network switching requirements more quickly when the screen is bright.

[0124] In some possible embodiments, when the number of times the terminal last lifted the suppression of the first-standard network is less than the first number, the first duration is the first value; or, when the number of times the terminal last lifted the suppression of the first-standard network is greater than or equal to the first number, the first duration is the second value; wherein the first value is less than the second value.

[0125] The number of times the terminal last unblocked the first-standard network can be understood as the number of times the terminal has previously unblocked the network. If the relationship between the number of times the terminal has previously unblocked the network and the first number is different, the first duration can take different values. Specifically, when the number of times the terminal has previously unblocked the network is less than the first number, the first duration takes the first value; when the number of times the terminal has previously unblocked the network is greater than or equal to the first number, the first duration takes the second value. The first value is less than the second value.

[0126] Through the above embodiment, the minimum time interval between two adjacent times when the terminal lifts the suppression of the first-standard network is related to the number of times the terminal has performed the suppression (that is, the number of times corresponding to the last time the suppression of the first-standard network was lifted). Before the number of times the terminal has performed the suppression reaches the first number, the first duration can take a smaller value. When the number of times the terminal has performed the suppression reaches / after the first number, the first duration can take a larger value, which can further avoid frequent network switching.

[0127] In some possible embodiments, the first quality requirement includes a first quality threshold; the signal quality of the second-standard network does not meet the first quality requirement, which may specifically include: the signal quality of the second-standard network is less than the first quality threshold for a duration greater than or equal to a second duration.

[0128] Among them, the first quality threshold can be understood as the minimum signal quality required for the second-standard network to meet the terminal's service needs. When the signal quality of the second-standard network is less than the first quality threshold, it can be determined that the second-standard network cannot meet the terminal's service needs. When the duration of the signal quality of the second-standard network is less than the first quality threshold, that is, the duration of the inability of the second-standard network to meet the terminal's service needs is greater than or equal to the second duration, it can be determined that the second-standard network continues to fail to meet the terminal's service needs, and further, it can be determined that the second-standard network environment has deteriorated, thereby triggering the terminal to release the suppression of the first-standard network.

[0129] Through the above embodiment, whether the signal quality of the second-standard network meets the first quality requirement can be judged based on the relationship between the duration that the signal quality of the second-standard network is less than the first quality threshold and the second duration. Specifically, when the duration is greater than or equal to the second duration, it can be determined that the signal quality of the second-standard network does not meet the first quality requirement, which helps to improve the accuracy of the judgment.

[0130] In some possible embodiments, when the terminal is in a call state, the first quality threshold is a third value; or, when the terminal is in a non-call state, the first quality threshold is a fourth value; wherein the third value is greater than the fourth value.

[0131] When the terminal resides on a second-standard network, the minimum signal quality required (i.e., the first quality threshold) can take different values ​​when the terminal is in a call state and in a non-call state. Specifically, when the terminal is in a call state, the first quality threshold takes a third value; when the terminal is in a non-call state, the first quality threshold takes a fourth value. The third value is greater than the fourth value.

[0132] Through the above embodiment, the first quality threshold when the terminal is in a call state may be greater than the first quality threshold when the terminal is in a non-call state, which helps to ensure the signal quality of the terminal in the call state.

[0133] In one possible implementation, the signal quality may be represented by a reference signal receiving power (RSRP). For example, a higher RSRP indicates better signal quality, and a lower RSRP indicates worse signal quality. Accordingly, the first quality threshold may include a first RSRP threshold. When the RSRP of the network cell of the second standard where the terminal resides is less than the duration of the first RSRP threshold and is greater than or equal to the second duration, it can be determined that the signal quality of the network of the second standard does not meet the first quality requirement.

[0134] In another possible implementation, the signal quality may be represented by a signal to interference plus noise ratio (SINR). For example, a higher SINR indicates better signal quality, and a lower SINR indicates worse signal quality. Accordingly, the first quality threshold may include a first SINR threshold. When the SINR of the network cell of the second standard in which the terminal resides is less than the duration of the first SINR threshold and is greater than or equal to the second duration, it can be determined that the signal quality of the network of the second standard does not meet the first quality requirement.

[0135] In another possible implementation, signal quality can be jointly represented by RSRP and SINR. Accordingly, the first quality threshold may include a first RSRP threshold and a first SINR threshold. When the RSRP of the LTE network cell where the terminal resides is less than the first RSRP threshold and the SINR is less than the first SINR threshold for a duration greater than or equal to a second duration, it can be determined that the signal quality of the second-standard network does not meet the first quality requirement.

[0136] It should be understood that both RSRP and SINR can relatively accurately reflect signal quality, and thus RSRP and / or SINR can be used to relatively accurately determine whether the signal quality of the LTE network meets the corresponding quality requirements. Optionally, SINR can also be replaced by signal-to-noise ratio (SNR).

[0137] It should be noted that the above-mentioned first quality requirement, first quality threshold, second duration, first RSRP threshold and first SINR threshold can all be pre-configured or pre-defined, and the embodiments of the present application do not limit them.

[0138] Through the embodiments of the present application, when a terminal suppresses a network of the first standard and resides on a network of the second standard, it can be determined whether to trigger the terminal to release the suppression of the network of the first standard based on whether the signal quality of the network of the second standard meets the first quality requirement. Specifically, the terminal can be triggered to release the suppression of the network of the first standard when the signal quality of the network of the second standard does not meet the first quality requirement, wherein the signal quality of the network of the second standard does not meet the first quality requirement, which can indicate that the network environment of the second standard has deteriorated. In this way, when the network environment of the second standard deteriorates, the terminal can promptly release the suppression of the network of the first standard, thereby avoiding the continuous residence in the poor network environment of the second standard affecting the use of services, and then facilitating a quick switch to a better network environment of the first standard.

[0139] Another method for connecting a terminal to a network is provided below. The method is applied to a terminal and may include but is not limited to the following steps 1 to 3.

[0140] Step 1: When the terminal resides on a network of the first standard, the terminal suppresses the network of the first standard when a second condition is met. The second condition includes: signal quality of the network of the first standard does not meet a second quality requirement.

[0141] The second condition can be understood as a condition that triggers the terminal to suppress the first-standard network, or as a condition that determines that the first-standard network environment where the terminal resides has deteriorated. In other words, when the first-standard network environment deteriorates, the terminal can be triggered to suppress the first-standard network.

[0142] Specifically, after the terminal resides on the first-standard network, it can detect the first-standard network. For example, it can monitor the environmental information of the physical layer and link layer and the interaction with the network through the modem to obtain the signal quality of the first-standard network. Then, based on whether the signal quality of the first-standard network meets the second quality requirement, it is determined whether to trigger the terminal to suppress the first-standard network.

[0143] In one possible case, the signal quality of the first-standard network does not meet the second quality requirement. In this case, the signal quality of the first-standard network can be considered poor, and the network environment of the first standard can be considered poor, which can trigger the terminal to suppress the first-standard network.

[0144] In another possible case, the signal quality of the first-standard network meets the second quality requirement. In this case, the signal quality of the first-standard network can be considered good, and the first-standard network environment can be considered good, so the terminal will not be triggered to suppress the first-standard network.

[0145] In some possible embodiments, the modem includes a second interface for suppressing the network of the first standard. The second interface may be a software interface, and illustratively, the second interface may be a function or command for suppressing the first standard.

[0146] When the second condition is met, the terminal suppresses the first-standard network. Specifically, when the AP or modem determines that the second condition is met, the AP calls the second interface to suppress the first-standard network. Alternatively, when the AP or modem determines that the second condition is met, the modem suppresses the SA network.

[0147] In some implementations, the AP can determine whether the second condition is met, and then, if the AP determines that the second condition is met, the AP calls the second interface of the modem to suppress the first-standard network; the modem can also determine whether the second condition is met, and then, if the modem determines that the second condition is met, the modem directly suppresses the first-standard network.

[0148] Through the above embodiment, when the terminal resides on a network of the first standard, whether to trigger the terminal to suppress the network of the first standard can be determined based on whether the signal quality of the network of the first standard meets the second quality requirement. Specifically, the terminal can be triggered to suppress the network of the first standard when the signal quality of the network of the first standard does not meet the second quality requirement, wherein the signal quality of the network of the first standard not meeting the second quality requirement can indicate that the network environment of the first standard has deteriorated. In this way, the terminal can be triggered to suppress the network of the first standard when the network environment of the first standard deteriorates, thereby preventing the terminal from continuously residing in a poor network environment of the first standard and affecting service use.

[0149] In some possible embodiments, the second quality requirement includes a second quality threshold; the signal quality of the first-standard network does not meet the second quality requirement, which may specifically include: the signal quality of the first-standard network is less than the second quality threshold for a duration greater than or equal to a third duration.

[0150] Among them, the second quality threshold can be understood as the minimum signal quality required for the first-standard network to meet the terminal's business needs. When the signal quality of the first-standard network is less than the second quality threshold, it can be determined that the first-standard network cannot meet the terminal's business needs. When the signal quality of the first-standard network is less than the second quality threshold for a duration, that is, when the duration of the first-standard network's inability to meet the terminal's business needs is greater than or equal to the third duration, it can be determined that the first-standard network continues to fail to meet the terminal's business needs, and further, it can be determined that the first-standard network environment has deteriorated, thereby triggering the terminal to suppress the first-standard network.

[0151] Through the above embodiment, whether the signal quality of the first-standard network meets the second quality requirement can be judged based on the relationship between the duration that the signal quality of the first-standard network is less than the second quality threshold and the third duration. Specifically, when the duration is greater than or equal to the third duration, it can be determined that the signal quality of the first-standard network does not meet the second quality requirement, which helps to improve the accuracy of the judgment.

[0152] In some possible embodiments, when the terminal resides on a network of the first standard, the minimum signal quality required when the terminal is in a call state and a non-call state (i.e., the second quality threshold) can take different values. The second quality threshold when the terminal is in a call state can be greater than the second quality threshold when the terminal is not in a call state, which helps to ensure the signal quality of the terminal in the call state.

[0153] In one possible implementation, the signal quality may be represented by RSRP. Accordingly, the second quality threshold may include a second RSRP threshold. When the RSRP of the first-standard network cell where the terminal resides is less than the second RSRP threshold for a duration that is greater than or equal to a third duration, it may be determined that the signal quality of the first-standard network does not meet the second quality requirement.

[0154] In another possible implementation, the signal quality may be represented by SINR. Accordingly, the second quality threshold may include a second SINR threshold. When the SINR of the first-standard network cell where the terminal resides is less than the second SINR threshold for a duration that is greater than or equal to a third duration, it may be determined that the signal quality of the first-standard network does not meet the second quality requirement.

[0155] In another possible implementation, the signal quality can be jointly represented by RSRP and SINR. Accordingly, the second quality threshold may include a second RSRP threshold and a second SINR threshold. When the RSRP of the SA network cell where the terminal resides is less than the second RSRP threshold and the SINR is less than the second SINR threshold for a duration greater than or equal to a third duration, it can be determined that the signal quality of the first-standard network does not meet the second quality requirement.

[0156] It should be understood that both RSRP and SINR can more accurately reflect signal quality, and thus RSRP and / or SINR can be used to more accurately determine whether the signal quality of the SA network meets the corresponding quality requirements. Optionally, SINR can also be replaced by SNR.

[0157] In other possible embodiments, the second quality requirement includes a freeze duration threshold; the signal quality of the first-standard network does not meet the second quality requirement, which may specifically include: the freeze duration of the terminal in the first-standard network is greater than the freeze duration threshold.

[0158] Among them, the freeze duration threshold can be understood as the maximum freeze duration of the terminal under the network that meets the terminal business needs. Specifically, when the terminal performs services (such as calls or data transmission) under the first-standard network, it can detect whether freeze occurs, and after detecting that freeze occurs, continue to detect the freeze duration. When the freeze duration of the terminal is greater than the freeze duration threshold, it can be determined that the first-standard network continues to fail to meet the terminal business needs, and then it can be determined that the first-standard network environment has deteriorated, which can trigger the terminal to suppress the first-standard network.

[0159] Through the above embodiment, whether the signal quality of the first-standard network meets the second quality requirement can be judged based on the relationship between the freeze duration of the terminal in the first-standard network and the freeze duration threshold. Specifically, when the freeze duration is greater than the freeze duration threshold, it can be determined that the signal quality of the first-standard network does not meet the second quality requirement, which helps to improve the accuracy of the judgment.

[0160] It should be noted that the above-mentioned second quality requirement, second quality threshold, third duration, second RSRP threshold, second SINR threshold and freeze duration threshold can all be pre-configured or pre-defined, and the embodiments of the present application do not limit them.

[0161] In some possible embodiments, the second quality threshold is smaller than the first quality threshold, and the third duration is smaller than the second duration.

[0162] Through the above embodiment, the second quality threshold and the third duration used when judging whether the signal quality of the first-standard network does not meet the quality requirements can be smaller than the first quality threshold and the second duration used when judging whether the signal quality of the second-standard network meets the quality requirements. In this way, the tolerance for the first-standard network (i.e., the network with a higher standard) is higher, which is conducive to staying in the network with a higher standard as much as possible.

[0163] Step 2: When the terminal suppresses the network of the first standard and resides on the network of the second standard, the terminal detects the signal quality of the network of the second standard and performs neighboring cell measurement.

[0164] After suppressing the first-standard network, the terminal can leave the first-standard network and reside on the second-standard network. After residing on the second-standard network, the terminal can detect the second-standard network to obtain the signal quality of the second-standard network and perform neighboring cell measurements.

[0165] Step three: When the first condition is met, the terminal unsuppresses the network of the first standard. The first condition includes: the signal quality of the network of the second standard does not meet the first quality requirement, and the terminal measures the network neighboring area of ​​the first standard, and the signal quality of the network neighboring area of ​​the first standard meets the third quality requirement.

[0166] The first condition can be understood as a condition that triggers the terminal to unblock the first-standard network, or it can be understood as a condition that determines that the second-standard network environment where the terminal is located has deteriorated and the first-standard network environment has improved. In other words, when the second-standard network environment where the terminal is located has deteriorated and the first-standard network environment has improved, the terminal can be triggered to unblock the first-standard network.

[0167] The first-standard network neighboring cell refers to a first-standard network cell obtained by the terminal through neighboring cell measurement. For example, the first-standard network is an SA network, and the SA network neighboring cell may also be referred to as an NR neighboring cell. The signal quality of the first-standard network neighboring cell can be used to reflect the first-standard network environment. Specifically, after measuring the first-standard network neighboring cell, the terminal can determine whether the signal quality of the first-standard network neighboring cell meets the third quality requirement.

[0168] In one possible scenario, the signal quality of the neighboring cell of the first-standard network meets the third quality requirement. In this case, the signal quality of the first-standard network can be considered good, and the network environment of the first standard can be considered good. In addition, the network environment of the second standard where the terminal resides deteriorates, which can trigger the terminal to release the suppression of the first-standard network.

[0169] In another possible scenario, the signal quality of the first-standard network does not meet the third quality requirement. In this case, the signal quality of the first-standard network can be considered poor, and further, the first-standard network environment can be considered poor. Therefore, even if the second-standard network environment where the terminal resides deteriorates, the terminal may not be triggered to release the suppression of the first-standard network.

[0170] Through the above embodiment, when the network environment of the second standard where the terminal resides deteriorates and the terminal detects a neighboring area of ​​the first standard network, it can be combined with whether the signal quality of the neighboring area of ​​the first standard network meets the third quality requirement to determine whether to trigger the terminal to release the suppression of the first standard network. Specifically, when the signal quality of the neighboring area of ​​the first standard network meets the third quality requirement, the terminal can be triggered to release the suppression of the first standard network, wherein the signal quality of the neighboring area of ​​the first standard network meets the third quality requirement, which can indicate that the network environment of the first standard is better. In this way, when the network environment of the second standard where the terminal resides deteriorates and the network environment of the first standard is better, the terminal can promptly release the suppression of the first standard network, thereby avoiding the continuous residence in the poor second standard network environment affecting the use of services, and then facilitating a quick switch to a better first standard network environment.

[0171] In some possible embodiments, the third quality requirement includes a third quality threshold; the signal quality of the first-standard network meets the third quality requirement, which may specifically include: the signal quality of the first-standard network is greater than or equal to the third quality threshold for a duration that is greater than or equal to a fourth duration.

[0172] Among them, the third quality threshold can be understood as the minimum signal quality required for the first-standard network to meet the terminal's business needs. When the signal quality of the first-standard network is greater than or equal to the third quality threshold, it can be determined that the first-standard network can meet the terminal's business needs. When the signal quality of the first-standard network is greater than or equal to the duration of the third quality threshold, that is, the duration of the first-standard network being able to meet the terminal's business needs is greater than or equal to the fourth duration, it can be determined that the first-standard network can continue to meet the terminal's business needs, and then it can be determined that the first-standard network environment has improved, thereby triggering the terminal to release the suppression of the first-standard network.

[0173] Through the above embodiment, whether the signal quality of the network neighboring area of ​​the first standard meets the third quality requirement can be judged based on the relationship between the duration that the signal quality of the network neighboring area of ​​the first standard is greater than or equal to the third quality threshold and the fourth duration. Specifically, when the duration is greater than or equal to the fourth duration, it can be determined that the signal quality of the network neighboring area of ​​the first standard meets the third quality requirement, which helps to improve the accuracy of the judgment.

[0174] In one possible implementation, the signal quality may be represented by RSRP. Accordingly, the third quality threshold may include a third RSRP threshold. When the RSRP of the first-standard SA network neighboring area detected by the terminal is greater than or equal to the duration of the third RSRP threshold and greater than or equal to the third fourth duration, it can be determined that the signal quality of the first-standard SA network meets the third quality requirement.

[0175] In another possible implementation, the signal quality may be represented by SINR. Accordingly, the third quality threshold may include a third SINR threshold. When the SINR of the neighboring cell of the first-standard network detected by the terminal is greater than or equal to the duration of the third SINR threshold and greater than or equal to the fourth duration, it can be determined that the signal quality of the first-standard network meets the third quality requirement.

[0176] In another possible implementation, the signal quality can be jointly represented by RSRP and SINR. Accordingly, the third quality threshold may include a third RSRP threshold and a third SINR threshold. When the RSRP of the first-standard network neighboring area detected by the terminal is greater than or equal to the third RSRP threshold and the SINR is greater than or equal to the third SINR threshold for a duration greater than or equal to a fourth duration, it can be determined that the signal quality of the first-standard network meets the third quality requirement.

[0177] It should be understood that both RSRP and SINR can more accurately reflect signal quality, and thus RSRP and / or SINR can be used to more accurately determine whether the signal quality of the SA network meets the corresponding quality requirements. Optionally, SINR can also be replaced by SNR.

[0178] It should be noted that the above-mentioned third quality requirement, third quality threshold, fourth duration, third RSRP threshold and third SINR threshold can all be pre-configured or pre-defined, and the embodiments of the present application do not limit them.

[0179] In some possible embodiments, the third quality threshold is less than or equal to the second quality threshold, and the fourth duration is less than or equal to the third duration.

[0180] Through the above embodiment, the third quality threshold and the fourth time length used when judging whether the signal quality of the first-standard network meets the suppression release condition can be smaller than the second quality threshold and the third time length used when judging whether the signal quality of the first-standard network meets the suppression condition. This is conducive to switching back to the first-standard network as soon as possible.

[0181] In addition, for the contents not specifically described in the above steps 1 to 3, you can refer to the relevant contents of the previous embodiment and will not repeat them here.

[0182] The following describes an embodiment of the present application by taking the first-standard network as an SA network and the second-standard network as an LTE network as an example.

[0183] Please refer to Figure 2, which is a flowchart of an existing method for a terminal to connect to an SA / LTE network. As shown in Figure 2, the method for a terminal to connect to a network includes the following steps S201 to S205.

[0184] S201: The terminal resides in the SA network.

[0185] S202: When the SA network does not meet the service demand of the terminal, the terminal suppresses the SA network.

[0186] S203: The terminal disconnects from the SA network.

[0187] S204: The terminal resides on the LTE network.

[0188] S205: When the preset suppression time is reached, the terminal releases the suppression of the SA network.

[0189] The suppression duration refers to the length of time the terminal suppresses the SA network. That is, during this suppression duration, the terminal always suppresses its use of the first-standard network. If the LTE network environment on which the terminal resides deteriorates during this suppression duration, the terminal will not be able to return to the original SA network, which may have improved, in a timely manner. This may affect the terminal's service usage, such as causing data lag and dropped calls.

[0190] Please refer to Figure 3, which is a flowchart of a method for a terminal to connect to an SA / LTE network provided by an embodiment of the present application. As shown in Figure 3, the method for the terminal to connect to the network may include but is not limited to the following steps S301 to S307.

[0191] S301: The terminal resides on the SA network. Specifically, the terminal may send a residency request to the SA network device, and the SA network device accepts the residency request, so that the terminal resides on the SA network.

[0192] S302: When the signal quality of the SA network does not meet the second quality requirement, the terminal suppresses the SA network.

[0193] S303: The terminal disconnects from the SA network. Specifically, the terminal may send a disconnection request to the SA network device. The SA network device accepts the disconnection request, so that the terminal disconnects from the SA network.

[0194] S304: The terminal resides on the LTE network. Specifically, the terminal may send a residency request to the LTE network device, and the LTE network device accepts the residency request, so that the terminal resides on the LTE network.

[0195] S305: When the signal quality of the LTE network does not meet the first quality requirement, and the terminal measures that the signal quality of the SA network neighboring cell meets the third quality requirement, the terminal releases the suppression of the SA network.

[0196] S306: The terminal disconnects from the LTE network. Specifically, the terminal may send a disconnection request to the LTE network device. The LTE network device accepts the disconnection request, so that the terminal disconnects from the LTE network.

[0197] S307: The terminal resides on the SA network. Specifically, the terminal may send a residency request to the SA network device, and the SA network device accepts the residency request, so that the terminal resides on the SA network.

[0198] For the specific contents of the above steps S301 to S307, please refer to the relevant descriptions in the previous embodiments, which will not be repeated here.

[0199] Through the above embodiment, when the terminal resides on the SA network, when the SA network environment deteriorates, the terminal can suppress the SA network and switch from the SA network to the LTE network, thereby avoiding the continuous residency in the poor SA network environment that affects service usage. When the terminal suppresses the SA network and resides on the LTE network, when the LTE network environment deteriorates and the SA network environment improves, the terminal can promptly unsuppress the SA network and return to the SA network from the LTE network, thereby avoiding the continuous residency in the poor LTE network environment that affects service usage, and can quickly return to a better SA network environment, which helps to improve the user's service experience.

[0200] The following describes the device involved in the embodiments of the present application.

[0203] It should be understood that the structures illustrated in the embodiments of the present application do not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown, or may combine or separate certain components, or arrange the components differently. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0204] The processor 110 may include one or more processing units. For example, the processor 110 may include an application processor (AP), a modem (also known as a baseband processor), a graphics processing unit (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), and / or a neural-network processing unit (NPU). The different processing units may be independent devices or integrated into one or more processors.

[0205] The controller may be the nerve center and command center of the electronic device 100. The controller may generate an operation control signal according to the instruction operation code and the timing signal to complete the control of fetching and executing instructions.

[0206] Processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in processor 110 is a cache memory. This memory can store instructions or data that have just been used or are being recycled by processor 110. If processor 110 needs to use the same instruction or data again, it can directly access the memory. This avoids duplicate accesses, reduces processor 110 latency, and thus improves system efficiency.

[0207] In some embodiments, the processor 110 may include one or more interfaces. The USB interface 130 is an interface that complies with USB standards and specifications, and may specifically be a Mini USB interface, a Micro USB interface, a USB Type-C interface, or the like. The USB interface 130 can be used to connect a charger to charge the electronic device 100, or to transfer data between the electronic device 100 and peripheral devices. It can also be used to connect headphones to play audio. This interface can also be used to connect to other electronic devices 100, such as AR devices.

[0208] The wireless communication function of the electronic device 100 can be implemented through the antenna 1, the antenna 2, the mobile communication module 150, the wireless communication module 160, the modem processor and the baseband processor.

[0209] Antenna 1 and antenna 2 are used to transmit and receive electromagnetic wave signals. Each antenna in electronic device 100 can be used to cover a single or multiple communication frequency bands. Different antennas can also be reused to improve antenna utilization.

[0210] The mobile communication module 150 can provide wireless communication solutions, including 2G / 3G / 4G / 5G, for the electronic device 100. The mobile communication module 150 may include at least one filter, a switch, a power amplifier, a low-noise amplifier (LNA), and the like. The mobile communication module 150 can receive electromagnetic waves from the antenna 1, filter and amplify the received electromagnetic waves, and transmit them to the modem processor for demodulation. The mobile communication module 150 can also amplify the signals modulated by the modem processor and convert them into electromagnetic waves for radiation via the antenna 1.

[0211] The modem processor may include a modulator and a demodulator. The modulator is used to modulate the low-frequency baseband signal to be transmitted into a medium- or high-frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After being processed by the baseband processor, the low-frequency baseband signal is passed to the application processor. The application processor outputs sound signals through an audio device (including but not limited to the speaker 170A, the receiver 170B, etc.) or displays images or videos through the display screen 194.

[0212] The wireless communication module 160 can provide wireless communication solutions including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc., which are applied to the electronic device 100. The wireless communication module 160 can be one or more devices that integrate at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via the antenna 2, frequency modulates and filters the electromagnetic wave signals, and sends the processed signals to the processor 110. The wireless communication module 160 can also receive the signal to be sent from the processor 110, frequency modulate it, amplify it, and convert it into electromagnetic waves for radiation through the antenna 2.

[0213] In some embodiments, antenna 1 of electronic device 100 is coupled to mobile communication module 150 , and antenna 2 is coupled to wireless communication module 160 , so that electronic device 100 can communicate with the network and other devices through wireless communication technology.

The application framework layer includes some predefined functions. For example, the application framework layer may include a window manager, content provider, view system, telephony manager, resource manager, and notification manager. The telephony manager provides terminal call functions, such as call status management (including connecting and ending calls).
