Description

Technical Field

[0001] The present application relates to communication technology, and is related to but not limited to wireless communication methods and devices, equipment, and chips. Background Art

[0002] Terminal devices such as mobile phones are becoming more and more important in our daily lives. Users use terminal devices to communicate with others through voice calls, video calls, short messaging services (SMS), etc. Users can also watch videos or browse the Internet through terminal devices. However, when using terminal devices, users may encounter various problems that affect their communication or Internet experience.

[0003] For example, in current high-speed mobile scenarios (such as high-speed rail and subway), even if the Long Term Evolution (LTE) service cell and the neighboring cell of the fifth generation mobile communication technology (5G) meet the signal conditions, the terminal device continues to report the B1 / B2 events of NR, and the actual terminal device still stays in the LTE service cell for a long time without returning to 5G. Usually, there are several reasons for this situation, which causes the terminal device to be unable to return to 5G for a long time on LTE. Since the terminal device has met the signal conditions for returning to NR (ie, 5G) on LTE, as the LTE signal gradually weakens in the mobile scenario, the terminal device will stay in LTE for a long time, and the Internet access will be obviously slow or unable to access the Internet normally, causing service jams and poor communication quality. Summary of the invention

At this time, the terminal device no longer waits for the network device to instruct to switch to another RAT standard, but autonomously / automatically / actively switches to the cell of another RAT standard (that is, the first cell of the first RAT standard determined autonomously by the terminal device); in this way, the terminal device can quickly switch to the cell of another standard, thereby minimizing the service stuck of the terminal device, which is beneficial to improving the user experience quality (QoE, Quality of Experience) of the terminal user for the service.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0023] In the following description, reference is made to “some embodiments”, “this embodiment”, “embodiments of the present application” and examples, etc., which describe a subset of all possible embodiments, but it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0024] In the related technology, in the current high-speed mobile scenarios (such as high-speed rail and subway), even if the LTE service cell and the NR neighboring cell meet the signal conditions, the terminal device continues to report the NR B1 / B2 event, and the network side's deployment intention also hopes to redirect from LTE back to NR, but the actual terminal device still stays in the LTE service cell for a long time without returning to 5G. The inventor of this application has studied and analyzed the above-mentioned related technologies and found that there are several reasons for this situation, which may cause the terminal device to be unable to return to 5G for a long time on LTE:

[0025] 1) Due to the Doppler frequency shift effect during high-speed movement, the terminal device cannot receive the RRC release redirection indication message from the network side, resulting in the terminal device continuously reporting NR B1 / B2 events and being unable to return to 5G;

[0026] 2) Due to uplink limitation or weak uplink coverage, the network side cannot receive the NR B1 / B2 events sent by the terminal device, resulting in the terminal device continuously reporting NR B1 / B2 events and being unable to respond to 5G;

[0027] 3) Due to weak downlink coverage, the network side cannot receive the NR B1 / B2 events sent by the terminal device, and the terminal device cannot receive the downlink RRC release redirection indication message from the network side, resulting in the terminal device continuously reporting NR B1 / B2 events and being unable to return to 5G.

[0028] The inventors of this application have discovered through research and analysis that the problem with the related technology is that since the terminal device has already met the signal conditions for returning to NR on LTE, as the LTE signal gradually weakens in a mobile scenario (the NR signal is good at this time), the terminal device will experience significantly slow Internet access or be unable to access the Internet normally on LTE for a long time.

[0029] In view of the analysis of the causes of the above technical problems, the embodiments of the present application provide multiple embodiments of the following wireless communication method. The method is applied to a terminal device, which can be various types of devices with wireless communication capabilities during implementation. For example, the terminal device may include a handheld device (such as a mobile phone), a wearable device (such as a smart watch, smart glasses, etc.), a tablet computer, a laptop computer, a vehicle-mounted device, a smart home device, a headset, a speaker, a keyboard, a mouse, a smart bracelet or an Internet of Things (IoT) device, etc. The function implemented by the method can be implemented by calling the program code by the processor in the terminal device. Of course, the program code can be stored in a computer storage medium. It can be seen that the terminal device includes at least a processor and a storage medium.

[0030] Figure 1A schematic diagram of the implementation flow of the wireless communication method provided in the embodiment of the present application is shown in FIG. Figure 1 As shown, the method may include the following steps 101 to 102:

[0031] Step 101, when the terminal device is determined to be in a first state, the terminal device selects a first cell from the neighboring cells of the first RAT standard according to the measurement result of the neighboring cells of the first RAT standard; the first state refers to a state in which service jam occurs when the terminal device is registered to a second cell of the second RAT standard in a high-speed mobile scenario; wherein the first RAT standard is different from the second RAT standard;

[0032] Step 102: The terminal device switches to a first cell of the first RAT standard.

[0033] It can be understood that in the wireless communication method provided in the embodiment of the present application, when the terminal device is determined to be in the first state, that is, the terminal device is in a high-speed mobile scenario and registered to the second cell of the second RAT standard, the service is stuck, which is an abnormal state. At this time, the terminal device no longer waits for the network device to instruct to switch to another RAT standard, but autonomously / automatically / actively switches to the cell of another RAT standard (that is, the first cell of the first RAT standard determined autonomously by the terminal device); in this way, the terminal device can quickly switch to the cell of another RAT standard, thereby minimizing the service stuck of the terminal device, which is beneficial to improving the user experience quality (QoE) of the terminal user for the service.

[0034] The following describes further optional implementations and related terms of each of the above steps.

[0035] Step 101, when the terminal device is determined to be in a first state, the terminal device selects a first cell from the neighboring cells of the first RAT standard based on the measurement results of the neighboring cells of the first RAT standard; the first state refers to a state in which service is stuck when the terminal device is registered to a second cell of the second RAT standard in a high-speed mobile scenario; wherein the first RAT standard is different from the second RAT standard.

[0036] It can be understood that the first state is an abnormal state in a high-speed mobile scenario, that is, the terminal device uses the connection link with the second cell to transmit services during high-speed movement, and the abnormal situation of service jam occurs. In the embodiment of the present application, there is no restriction on the method for determining the occurrence of service jam when registering to the second cell of the second RAT standard. In short, in the first state, the terminal device has service jam based on the second cell.

[0037] In some embodiments, the terminal device determines that service jam occurs when registering to a second cell of a second RAT standard, including: the terminal device determines, when registering to the second cell, that service jam occurs when registering to the second cell according to a target parameter; wherein the target parameter includes one or more of the following first to fourth parameters:

[0038] a first parameter; the first parameter is used to characterize the channel quality of the second cell;

[0039] A second parameter; the second parameter is used to characterize the user experience quality (QoE);

[0040] A third parameter; the third parameter is used to characterize the number of times the first event is reported to the network device within the first duration; wherein the first event is used to trigger a switch from the second RAT standard to the first RAT standard;

[0041] The fourth parameter is used to indicate whether the indication information sent by the network device is received; wherein the indication information is used to indicate switching to the cell of the first RAT standard.

[0042] In an embodiment of the present application, the terminal device determines, based on the target parameters, the conditions for service jamming when registering to the second cell without any restriction. In short, if the channel quality of the second cell represented by the first parameter is poor (for example, greater than a specific threshold or less than a specific threshold), the QoE represented by the second parameter is poor (for example, greater than a specific threshold or less than a specific threshold), the number of times the first event is reported represented by the third parameter is greater than or equal to a specific threshold, and the fourth parameter indicates that the standard information sent by the network device has not been received, and one or more of the above conditions are met, it is determined that service jamming occurs when registering to the second cell.

[0043] Exemplarily, in some embodiments, the terminal device determines, according to the target parameter, that service jam occurs when registering to the second cell of the second RAT standard, including: the terminal device determines, when determining that the target parameter satisfies a preset condition, that service jam occurs when registering to the second cell of the second RAT standard; wherein the preset condition includes one or more of the following:

[0044] The first parameter is less than or equal to a first threshold; the first parameter is positively correlated with the channel quality of the second cell;

[0045] The second parameter is less than or equal to a second threshold; the second parameter is positively correlated with the user experience quality;

[0046] The third parameter is greater than or equal to a third threshold;

[0047] The fourth parameter indicates that the indication information sent by the network device has not been received.

[0048] Of course, in the case where the first parameter is negatively correlated with the channel quality of the second cell, the above "the first parameter is less than or equal to the first threshold" can be replaced by "the first parameter is greater than or equal to the fourth threshold". In the case where the second parameter is negatively correlated with the user experience quality, the above "the second parameter is less than or equal to the second threshold" can be replaced by "the second parameter is greater than or equal to the fifth threshold".

[0049] In the embodiment of the present application, there is no restriction on the type of the first parameter, which can be various. In short, the first parameter can characterize the channel quality of the second cell. For example, the first parameter is a reference signal received power (RSRP, Reference Signal Receiving Power), a reference signal received quality (RSRQ, Reference Signal Receiving Quality) or a signal to interference plus noise ratio (SINR, Signal to Interference plus Noise Ratio), etc. Alternatively, the second parameter is a comprehensive value based on at least two of RSRP, RSRQ, and SINR.

[0050] It is understood that the second parameter is used to characterize the user experience quality (QoE). In some embodiments, the first parameter characterizes the overall quality perceived by the user when using the network service. At the data link level, QoE can involve multiple aspects, such as data transmission rate, delay, jitter, packet loss rate, etc. These data link indicators jointly determine the user's satisfaction when using the network service. In a possible implementation, the terminal device can determine the second parameter based on one or more of the data transmission rate, delay, jitter, and packet loss rate.

[0051] In the embodiment of the present application, there is no restriction on the type of the first event, as long as it can trigger switching from the second RAT standard to the first RAT standard. For example, the first event includes a B1 event of NR and / or a B2 event of NR; in some embodiments, the first RAT standard is the NR standard, and the second RAT standard is the LTE standard.

[0052] It can be understood that the B1 event of NR: indicates that the signal quality of the neighboring cell of the heterogeneous system / heterogeneous standard (relative to the current LTE system, that is, the NR system) is higher than the specified threshold. This event is usually used to trigger the inter-system / inter-standard switching process from LTE to NR.

[0053] NR B2 event: indicates that the signal quality of the LTE serving cell is lower than the specified threshold 1, and the signal quality of the neighboring cell of the heterogeneous system (NR system) is higher than the specified threshold 2. This event is also used to trigger the inter-system / inter-standard handover process from LTE to NR.

[0054] As mentioned above, the fourth parameter is used to characterize whether the indication information sent by the network device is received. Among them, this application does not limit the type of the indication information. In short, the indication information is information used to indicate switching to the cell of the first RAT standard. Exemplarily, in some embodiments, the indication information is used to indicate the release of the RRC connection with the second cell and to indicate the frequency of switching to a specific cell of the first RAT standard. For example, the indication information is RRC release and redirection indication information sent by the network device.

[0055] As mentioned above, the terminal device determines that service freeze occurs when registering to the second cell of the second RAT standard when determining that the target parameter meets the preset conditions. For example, if the current LTE service cell RSRP is lower than a certain threshold, and the current data link QoE is lower than a certain threshold, and N NR B1 / B2 events are reported within T seconds, and no RRC release indication and redirection indication are received from the network device, it is determined that service freeze occurs when registering to the LTE cell.

[0056] Step 102: The terminal device switches to a first cell of the first RAT standard.

[0057] In some embodiments, the terminal device switches to the first cell of the first RAT standard, including: the terminal device releases the RRC connection with the second cell and performs a registration process of the first cell to switch to the first cell of the first RAT standard.

[0058] It can be understood that in the wireless communication method provided in the embodiment of the present application, when the terminal device is determined to be in the first state, that is, the terminal device is in a high-speed mobile scenario and registers with the second cell of the second RAT standard, the service jam occurs in this abnormal state. At this time, it no longer waits for the network device to instruct to release the current RRC connection and redirection instruction, but autonomously / automatically / actively selects the first cell / suitable cell / target cell from the neighboring area of ​​the first RAT standard based on the measurement results of the neighboring area of ​​the first RAT standard, and autonomously / automatically / actively releases the RRC connection with the second cell, and autonomously / automatically / actively performs the registration process of the first cell to switch to a cell of another RAT standard (that is, the first cell of the first RAT standard); in this way, the terminal device can quickly switch to a cell of another RAT standard, thereby minimizing the service jam of the terminal device, which is beneficial to improving the user experience quality (QoE, Quality of Experience) of the terminal user for the service.

[0059] In the embodiment of the present application, there is no restriction on the types of the first RAT standard and the second RAT standard. In short, the first RAT standard and the second RAT standard can be different. In some embodiments, the first RAT standard is higher than the second RAT standard. For example, the second RAT standard is LTE, 3G or 2G, etc., and the first RAT standard is NR standard or higher.

[0060] It can be understood that in the wireless communication method provided in the embodiment of the present application, when the terminal device is determined to be in the first state, that is, the terminal device is in a high-speed mobile scenario and registered to the second cell of the second RAT standard, the service is stuck, which is an abnormal state. At this time, the terminal device no longer waits for the network device to instruct to switch to the high RAT standard, but autonomously / automatically / actively determines the first cell of the first RAT standard and switches to the cell of the high RAT standard (that is, the first cell of the first RAT standard); in this way, the terminal device can quickly switch to the cell of the high standard, thereby minimizing the service stuck of the terminal device, which is beneficial to improving the user experience quality (QoE) of the terminal user for the service.

[0061] For another example, the first RAT standard is LTE or NR, etc., and the second RAT standard is 3G or 2G, etc. In some other embodiments, the first RAT standard is lower than the second RAT standard.

[0062] The following examples describe possible implementation schemes of the wireless communication methods described in one or more of the above embodiments.

[0063] As mentioned above, the inventors of this application have studied and analyzed the above-mentioned related technologies and found that there are several reasons for this situation, which may cause the terminal device to be unable to return to 5G for a long time on LTE:

[0064] 1) Due to the Doppler frequency shift effect during high-speed movement, the terminal device cannot receive the RRC release redirection indication message from the network side, resulting in the terminal device continuously reporting NR B1 / B2 events and being unable to return to 5G;

[0065] 2) Due to uplink limitation or weak uplink coverage, the network side cannot receive the NR B1 / B2 events sent by the terminal device, resulting in the terminal device continuously reporting NR B1 / B2 events and being unable to respond to 5G;

[0066] 3) Due to weak downlink coverage, the network side cannot receive the NR B1 / B2 events sent by the terminal device, and the terminal device cannot receive the downlink RRC release redirection indication message from the network side, resulting in the terminal device continuously reporting NR B1 / B2 events and being unable to return to 5G.

[0067] The inventors of this application have discovered through research and analysis that the problem with the related technology is that since the terminal device has already met the signal conditions for returning to NR on LTE, as the LTE signal gradually weakens in a mobile scenario (the NR signal is good at this time), the terminal device will experience significantly slow Internet access or be unable to access the Internet normally on LTE for a long time.

[0068] In view of this, in an embodiment of the present application, a wireless communication method is provided. When the terminal device identifies a high-speed mobile scenario, the signal condition of the current LTE service cell is poor, and the current data link QoE indicator is poor, and the neighboring cell NR B1 / B2 continues to report within a certain period of time (for example, 3s) but has not received the RRC release indication and redirection indication of the network device, the terminal actively triggers the action of quickly returning to NR to reduce the terminal user's service jams and significantly improve the terminal user's service QOE experience.

[0069] In the embodiment of the present application, there is no restriction on whether the terminal device is in a high-speed movement scenario. The terminal device can be judged based on the moving speed or other technical means to identify the high-speed movement scenario. For example, if the moving speed of the terminal device is greater than or equal to the preset speed threshold, it is determined to be in a high-speed movement scenario. For another example, if the terminal device recognizes that it is in a predefined means of transportation (such as high-speed rail, subway, car, etc.), it is determined to be in a high-speed movement scenario.

[0070] In a possible implementation, if (the current LTE service cell RSRP is lower than a certain threshold) && (the current data link QoE indicator is lower than a certain threshold) && (NR B1 / B2 is reported N times within T seconds and no RRC release redirection is received from the network side), the terminal actively triggers the action of fast returning to NR. The symbol "&&" means "and".

[0071] It can be understood that in the wireless communication method provided in the embodiment of the present application, the gradual weakening of the LTE signal (the NR signal is good at this time) is identified through the high-speed mobile scenario. In the scenario where the terminal user stays in LTE for a long time and the Internet access is obviously slow or cannot be accessed normally, the terminal actively triggers the action of quickly returning to NR, thereby reducing the terminal user's service lag as much as possible and significantly improving the terminal user's service QOE experience.

[0072] In an embodiment of the present application, a solution is provided to the problem of slow or inability to return to 5G in high-speed mobile scenarios. Based on the 3GPP protocol, by identifying high-speed mobile scenarios, signal condition judgments and data link quality judgments, the terminal actively triggers the action of quickly returning to 5G, thereby minimizing the service lag of terminal users, making up for the shortcomings of the 3GPP protocol, and improving the user data network experience.

[0073] It should be noted that although the steps of the method in the present application are described in a specific order in the drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and / or one step may be decomposed into multiple steps, etc.; or, steps in different embodiments may be combined into a new technical solution.
