[0035] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0036] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0037] Next, in conjunction with the accompanying drawings, the non-standalone networking NSA mode communication method provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0038] In an embodiment of the present application, a communication method in NSA mode is provided, and this method can be executed by a mobile terminal. Please refer to Figure 1 , this figure is a schematic flow diagram of the communication method in NSA mode according to an embodiment of the present application.

[0039] As Figure 1 shown, the communication method in NSA mode according to the embodiment of the present application includes the following steps 12 to step 18.

[0040] Step 12, detecting the communication quality of the 5G communication service of the mobile terminal in the first cell, where the mobile terminal supports 5G capabilities in NSA mode and reports 5G capability support to the first cell.

[0041] When the mobile terminal supports 5G capabilities in NSA mode and reports its 5G capabilities to the corresponding cell A, when the access cell A is the anchor cell, if the mobile terminal powers on, connects to the network, and registers with cell A, the mobile terminal can then conduct 5G service communication in cell A.

[0042] When the mobile terminal is provided with 5G communication services by cell A, it is necessary to detect the communication quality of the 5G communication services provided by cell A to the mobile terminal, in order to determine whether there is an abnormal communication situation in the LTE anchor base station corresponding to cell A.

[0043] Optionally, as Figure 2 shown, detecting the communication quality of the 5G communication services of the mobile terminal in the first cell includes steps 202 to 206.

[0044] Step 202, determine whether the mobile terminal is in a 5G communication service state.

[0045] To determine whether the mobile terminal is in a service state, it can be checked whether there are more than N1 applications in the mobile terminal's background using the data network simultaneously, or whether the overall network speed of the mobile terminal is above N2 kB / s. N1 and N2 are corresponding threshold values, stored in the memory medium of the mobile terminal. The values of N1 and N2 can be appropriately adjusted according to different scenarios, such as video scenarios, game scenarios, browser scenarios, etc. In one embodiment, the value of N1 is between 2 and 4, generally set to 3; the value of N2 is between 80 and 120, generally set to 100.

[0046] Step 204, when in a 5G communication service state, detect the number of times the mobile terminal receives a 5G communication service with lags within a preset time.

[0047] By determining whether the current 5G communication service has lags or is not smooth, the communication quality of the 5G communication service between the mobile terminal and cell A is detected. For example, the mobile terminal checks whether it receives N3 or more times of communication service lags or lack of smoothness within T1 seconds.

[0048] T1 is the corresponding threshold value, stored in the memory medium of the mobile terminal. The value of T1 can be appropriately adjusted according to different scenarios. In one embodiment, the value of T1 is between 20 and 40, generally set to 30.

[0049] Step 206, if the number is greater than the preset threshold, detect that the communication quality of the 5G communication service is lower than the preset index.

[0050] If this condition is met, it indicates that the communication quality of the current 5G communication service is lower than the preset index, and the communication quality is not good. Subsequently, it is necessary to proceed to step 14 to further detect abnormalities in cell A, which will be described in detail below.

[0051] If the mobile terminal checks that the communication service received within T1 seconds is jammed or not smooth and is less than N3, it means that the communication quality of the current 5G communication service is qualified, and cell A can continue to provide 5G communication services for the mobile terminal's 5G communication service.

[0052] Step 14: If the communication quality of the 5G communication service is lower than a preset indicator, perform an abnormality detection of the 5G communication service on the first cell.

[0053] As described above, if the communication quality of the current 5G communication service is detected to be poor in step 12, it is necessary to perform an abnormality detection on cell A to detect whether the anchor base station corresponding to cell A is an abnormal base station.

[0054] Optionally, in one embodiment, the abnormality detection of the 5G communication service of the first cell includes: determining whether the first cell responds to the data transmission request of the mobile terminal; and detecting that there is an abnormality in the 5G communication service of the first cell when the first cell does not respond to the data transmission request of the terminal.

[0055] For example, the mobile terminal continuously sends more than N4 uplink data packets within T2 seconds, but does not receive any downlink data packets sent by the base station, that is, the network does not respond to the terminal's data transmission request.

[0056] T2 and N4 are corresponding threshold values, which are stored in the memory medium of the mobile terminal. The values of T2 and N4 can be adjusted appropriately according to different scenarios. In one embodiment, T2 is between 5 and 15, and is generally set to 10; N4 is between 4 and 8, and is generally set to 6.

[0057] In this embodiment, the data sent by the mobile terminal cannot receive a response from the base station network, resulting in an interruption or freeze in the 5G communication of the mobile terminal, causing poor communication quality of the 5G communication service.

[0058] Optionally, in one embodiment, the abnormality detection of the 5G communication service of the first cell includes: determining whether the packet data convergence protocol PDCP sequence number of the first cell is continuous; and if the PDCP sequence number is discontinuous, detecting that there is an abnormality in the 5G communication service of the first cell.

[0059] The base station configures the bearer of the Main Cell Group (MCG) on the Packet Data Convergence Protocol (PDCP) of the New Radio (NR), and configures the PDCP sequence number to 18 bits. The PDCP sequence numbers must be continuous for correct data transmission. A large jump in the PDCP sequence numbers indicates that the base station is not compatible with the configuration of the NR PDCP sequence number being 18 bits. In some scenarios, such as during handover, the incompatibility causes the mobile terminal and the base station to have inconsistent understandings of the PDCP sequence number of 18 bits, resulting in inconsistent PDCP sequence numbers and causing the interruption of 5G communication data transmission.

[0060] In this embodiment, for the data packet sent by the base station to the mobile terminal, due to the incorrect PDCP sequence number, the mobile terminal cannot parse it out, resulting in the interruption or lag of the 5G communication of the mobile terminal and causing poor communication quality of the 5G communication service.

[0061] In the above embodiment, the reason for the poor communication quality of the 5G communication service between cell A and the mobile terminal may be that the conflicting base station corresponding to cell A has abnormal 5G communication due to imperfect network optimization.

[0062] Therefore, in one embodiment, before performing abnormal detection on the 5G communication service of cell A, it may also include first determining whether cell A is an abnormal cell.

[0063] As Figure 3 shown, it includes the following steps 302 to step 306.

[0064] Step 302, obtain the network configuration parameters of the first cell.

[0065] The network configuration parameters may include, for example, the PDCP sequence number corresponding to the cell, NR measurement, and NSA mode registration of the mobile terminal, etc.

[0066] Step 304, determine whether the first cell is an abnormal cell according to the network configuration parameters;

[0067] First, determine whether the PDCP entity of the first cell is configured in the NR mode or whether the PDCP sequence number meets a preset format, for example, the PDCP sequence number is 18 bits.

[0068] If the PDCP entity of the first cell is configured in the NR mode and the PDCP sequence number meets the preset format, then determine whether the first cell is configured with NR measurement or whether the mobile terminal has registered the NSA mode in the first cell.

[0069] If the first cell is not configured with NR measurement and the mobile terminal has not registered for the NSA mode in the first cell, it is determined that the first cell is an abnormal cell.

[0070] If the mobile terminal cannot register for the NSA in cell A, the mobile terminal cannot connect to cell A.

[0071] If cell A is not configured with neighbor cell measurement for 5G NR, neighbor cell measurement cannot be performed. Without measurement, the mobile terminal cannot connect to cell A to achieve 5G communication.

[0072] Therefore, if a cell is not configured with NR measurement and the mobile terminal has not successfully registered for the NSA in this cell, it indicates that the cell is an abnormal cell, and the corresponding base station is an abnormal base station, which cannot normally provide 5G communication services to mobile terminals that support 5G capabilities and report.

[0073] Step 306, if so, execute the step of performing abnormal detection on the 5G communication service of the first cell.

[0074] Thus, the mobile terminal can perform cell abnormal detection by combining the cell configuration and network transmission, so as to achieve accurate detection of the abnormality of the 5G communication service of the first cell.

[0075] Step 16, if there is an abnormality in the 5G communication service of the first cell, obtain a second cell that supports the 5G communication service among the available neighbor cells corresponding to the first cell.

[0076] The definition of the available neighbor cell B is: the mobile terminal can register for normal communication in B, that is, the Public Land Mobile Network (PLMN) of cell B meets the requirements, and no abnormality is detected in cell B. In addition, the signal of cell B meets the standard, and the signals include, for example, the Reference Signal Receiving Power (RSRP), the LTE Reference Signal Receiving Quality (RSRQ), and the Signal-to-noise ratio (SNR). Among them, RSRP > RSRP_th; RSRQ > RSRQ_th; SNR > SNR_th.

[0077] RSRP_th, RSRQ_th, and SNR_th are corresponding threshold values, which are stored in the memory medium of the mobile terminal. Their values can be adjusted appropriately according to different scenarios. In one embodiment, the value of RSRP_th is between -120 and -95, and is generally set to -105; the value of RSRG_th is between -16 and -8, and is generally set to -12; the value of SNR_th is 0.

[0078] Optionally, after obtaining the second cell that supports 5G communication services among the available neighboring cells corresponding to the first cell, it further includes: if the mobile terminal camps on the first cell, triggering a connected state radio link failure, or de-registering from the network in the idle state and re-registering on the second cell to prohibit the mobile terminal from registering on the first cell.

[0079] That is, the mobile terminal is disabled from accessing cell A for a certain period of time. After the mobile terminal registers on cell B, in the connected state, the measurement report of cell A can be blocked, and in the idle state, it will not reselect to cell A.

[0080] This period of time can be 5 - 20 minutes, and is usually set to 10 minutes.

[0081] Step 18, in the presence of the second cell, switch the access cell of the mobile terminal from the first cell to the second cell and report the 5G capability support.

[0082] Thus, when it is detected that there is an abnormal 5G communication between the mobile terminal and cell A, by switching the access cell of the mobile terminal to the neighboring cell B that can normally support 5G communication, it is possible to avoid long-term communication interruption and lag of the mobile terminal, ensure the normal communication service of the mobile terminal, and thus improve the 5G communication fluency in the NSA mode.

[0083] In one embodiment, if the second cell or the available neighboring cell does not exist, the 5G capability support of the mobile terminal is turned off and reported to the first cell.

[0084] After the mobile terminal turns off the 5G capability and reports it, cell A will not query the 5G capability of the mobile terminal, nor will it configure NRPDCP. Therefore, there will no longer be 5G communication abnormal problems on such abnormal base stations.

[0085] To avoid interruption of the communication service of the mobile terminal, optionally, in one embodiment, the method further includes: switching the 5G capability support of the mobile terminal to 4G capability support.

[0086] When Community A provides 5G communication services, abnormalities occur, but communication services in other modes, such as 2G / 3G / 4G, are normal. Therefore, when 5G communication is abnormal, switching the mobile terminal to 4G capability support allows Community A to continue providing uninterrupted communication services to the mobile terminal, ensuring the normal operation of the mobile terminal's communication services.

[0087] In one embodiment, when the mobile terminal leaves the first community, it is determined whether the departure duration exceeds a second preset duration; if so, the 5G capability support of the mobile terminal is turned on and reported to the corresponding access community.

[0088] For example, the mobile terminal determines whether it has left Community A for more than T4 seconds. If so, it is determined that the mobile terminal has disconnected from the abnormal Community A. At this time, it is necessary to turn on the 5G capability support of the mobile terminal again and report it to the accessible community to obtain normal 5G communication services from the access community.

[0089] T4 is the corresponding threshold value, which is stored in the memory medium of the mobile terminal. The value of T4 can be appropriately adjusted according to different scenarios. In one embodiment, the value of T4 is between 20 and 40, and is generally set to 30.

[0090] In the embodiments of the present application, first, the communication quality of the 5G communication service of the mobile terminal accessing the community is detected. When the communication quality is lower than the preset index, the 5G communication service of the community is further detected. When the 5G communication service of the community is abnormal, another community that also supports the 5G communication service is obtained and switched to. Therefore, when the LTE network communication of the NSA anchor community is abnormal, specific abnormalities of a specific base station can be accurately identified, and this abnormal community can be promptly left and switched to a community that can provide normal 5G communication, avoiding service delay or interruption and improving the communication fluency in the NSA mode. Correspondingly, the stability of the mobile terminal's communication service and the user experience are improved.

[0091] In addition, by turning on and off the 5G capability support of the mobile terminal, the configuration of abnormal base stations can be effectively adjusted, providing stable and reliable communication services for the mobile terminal.

[0092] Reference Figure 4 , Figure 4 is an overall process example of the communication method in the NSA mode of the embodiments of the present application. In this embodiment, the mobile terminal is a mobile station.

[0093] As shown in the figure, it includes the following steps:

[0094] Step 101, the mobile station conducts communication services in the LET community, and the mobile station reports 5G capability support.

[0095] Step 102: Determine whether the mobile station is in a service state and whether service jamming is detected. If so, proceed to Step 103; if not, end.

[0096] Step 103: Determine whether the cell network configures a PDCP entity on NR and the PDCP sn (PDCP sequence number) is equal to 18 bits. If so, proceed to Step 104; if not, end.

[0097] Step 104: Determine whether the cell network configures NR measurement or whether Cell A has registered for LTE and NR dual connectivity (E-UTRA NR Dual Connectivity, ENDC), that is, it has registered; if the cell network does not configure NR measurement and Cell A has not registered for NSA, proceed to Step 105; if not, end.

[0098] Step 105: Determine whether there are no downlink data packets within 10 consecutive seconds in the cell network; or whether the PDCP sn jumps significantly. If so, proceed to Step 106; if not, end.

[0099] Step 106: Determine whether there is an available LTE neighbor cell B. If so, proceed to Step 107, then proceed to Step 108.

[0100] Step 107: The mobile station disables Cell A for N minutes; after N minutes, the disable is unlocked.

[0101] Step 108: The mobile station turns off 5G capability support and reports Cell A.

[0102] Step 109: Determine whether the mobile station has dropped the connection to Cell A. If so, proceed to Step 110; if not, end.

[0103] Step 110: The mobile station turns on 5G capability and reports it.

[0104] Optionally, the embodiment of the present application further provides a communication method in a non-standalone networking NSA mode, as Figure 5 shown, including:

[0105] Step 402: Detect the communication quality of the 5G communication service of the mobile terminal in the first cell. The mobile terminal supports 5G capability in the non-standalone networking NSA mode and reports 5G capability support to the first cell;

[0106] Step 404: If the communication quality of the 5G communication service is lower than the preset index, perform an abnormal detection on the 5G communication service of the first cell;

[0107] Step 406: If there is an abnormality in the 5G communication service of the first cell, turn off the 5G capability support of the mobile terminal and report it to the first cell;

[0108] Step 408, switch the 5G capability support of the mobile terminal to 4G capability support.

[0109] In the embodiment of the present application, first detect the communication quality of the 5G communication service of the mobile terminal accessing the cell. When the communication quality is lower than the preset index, further detect the 5G communication service of the cell. When the 5G communication service of the cell is abnormal, directly stop supporting 5G in the cell and switch to 4G communication. Thus, when the LTE network communication of the NSA anchor cell is abnormal, the specific abnormality of the specific base station can be accurately identified, and the 5G communication of the abnormal cell can be timely switched to the normal 4G communication, avoiding service delay or interruption and improving the stability of the mobile terminal communication service and the user experience.

[0141] When the mobile terminal leaves the first cell, determine whether the duration of leaving exceeds a second preset duration;

[0142] If so, open the 5G capability support of the mobile terminal and report it to the corresponding access cell.

[0143] In the embodiments of the present application, first, the communication quality of the 5G communication service of the cell accessed by the mobile terminal is detected. When the communication quality is lower than the preset index, the 5G communication service of the cell is further detected. When the 5G communication service of the cell is abnormal, another cell that also supports 5G communication services is obtained and switched to. Thus, when the LTE network communication of the NSA anchor cell is abnormal, the specific abnormality of a specific base station can be accurately identified, and this abnormal cell can be promptly left and switched to a cell that can communicate normally in 5G, avoiding causing service delay or interruption and improving the communication fluency in the NSA mode. Correspondingly, the stability of the communication service of the mobile terminal and the user experience are improved.

[0147] The second detection module 840 performs an anomaly detection on the 5G communication service of the first cell if the communication quality of the 5G communication service is lower than a preset index.

[0148] The shutdown module 870 shuts down the 5G capability support of the mobile terminal and reports it to the first cell if there is an anomaly in the 5G communication service of the first cell.

[0149] The switching module 890 switches the 5G capability support of the mobile terminal to 4G capability support.

[0150] In this embodiment, the first detection module and the second detection module are the same as Figure 6 the first detection module and the second detection module in the embodiment.

[0151] The communication device in the NSA mode provided by the embodiment of the present application can implement Figure 5 each process implemented by the method embodiment. To avoid repetition, it will not be elaborated here.

[0152] The communication device in the NSA mode in the embodiment of the present application can be a device, or a component, an integrated circuit, or a chip in a terminal.

The operating system can be the Android operating system, the iOS operating system, or other possible operating systems. The embodiment of the present application does not make a specific limitation.

[0154] The communication device in the NSA mode provided by the embodiment of the present application can implement Figures 1 to 5 each process implemented by the method embodiment. To avoid repetition, it will not be elaborated here.

[0155] Optionally, as Figure 8As shown in the figure, an embodiment of the present application further provides an electronic device 900, including a processor 940, a memory 920, a program or instruction stored on the memory 920 and executable on the processor 940. When the program or instruction is executed by the processor 940, it implements each process of the communication method embodiment in the above NSA mode and can achieve the same technical effect. To avoid repetition, it will not be elaborated here.

[0156] It should be noted that the electronic device in the embodiment of the present application includes the above-mentioned mobile electronic device.

[0157] Figure 9 It is a schematic diagram of the hardware structure of an electronic device according to an embodiment of the present application.

[0158] The electronic device 1000 includes, but is not limited to: a radio frequency unit 1001, a network module 1002, an audio output unit 1003, an input unit 1004, a sensor 1005, a display unit 1006, a user input unit 1007, an interface unit 1008, a memory 1009, and a processor 1010 and other components.

[0159] Those skilled in the art can understand that the electronic device 1000 may further include a power supply (such as a battery) for supplying power to each component. The power supply can be logically connected to the processor 1010 through a power management system, so as to implement functions such as management of charging, discharging, and power consumption management through the power management system. Figure 9 The structure of the electronic device shown in the figure does not constitute a limitation on the electronic device. The electronic device may include more or fewer components than shown, or combine certain components, or have different component arrangements, which will not be elaborated here.

[0160] Among them, the processor 1010 is used to detect the communication quality of the 5G communication service of the mobile terminal in the first cell. The mobile terminal supports 5G capabilities in the non-standalone networking NSA mode and reports the 5G capability support to the first cell.

[0161] If the communication quality of the 5G communication service is lower than a preset index, abnormal detection of the 5G communication service of the first cell is performed.

[0162] If there is an abnormality in the 5G communication service of the first cell, a second cell that supports the 5G communication service among the available neighboring cells corresponding to the first cell is obtained.

[0163] In the case where the second cell exists, the access cell of the mobile terminal is switched from the first cell to the second cell and the 5G capability support is reported.

[0164] In the embodiments of the present application, first, the communication quality of the 5G communication service of the cell accessed by the mobile terminal is detected. When the communication quality is lower than the preset index, the 5G communication service of the cell is further detected. When the 5G communication service of the cell is abnormal, another cell that also supports the 5G communication service is obtained and switched to. Thus, when the LTE network communication of the NSA anchor cell is abnormal, the specific abnormality of a specific base station can be accurately identified, and this abnormal cell can be left in time and switched to a cell that can communicate normally in 5G, avoiding causing service delay or interruption and improving the communication fluency in the NSA mode. Accordingly, the stability of the communication service of the mobile terminal and the user experience are improved.

[0165] Optionally, the processor 1010 is further configured to obtain the network configuration parameters of the first cell before performing the abnormality detection of the 5G communication service on the first cell;

[0166] Judge whether the first cell is an abnormal cell according to the network configuration parameters;

[0167] If so, execute the step of performing the abnormality detection of the 5G communication service on the first cell.

[0168] Thus, the mobile terminal can combine the configuration of the cell and network transmission to perform cell abnormality detection, so as to achieve accurate detection of the abnormality of the 5G communication service of the first cell.

[0169] Optionally, the processor 1010 is further configured to, if the second cell or the available neighboring cell does not exist, turn off the 5G capability support of the mobile terminal and report it to the first cell; switch the 5G capability support of the mobile terminal to 4G capability support. When the mobile terminal leaves the first cell, judge whether the leaving duration exceeds a second preset duration; if so, turn on the 5G capability support of the mobile terminal and report it to the corresponding accessed cell.

[0170] Thus, by turning on and off the 5G capability support of the mobile terminal, the abnormal base station configuration can be effectively adjusted to provide a stable and reliable communication service for the mobile terminal.

[0171] In addition, in one embodiment, the processor 1010 is configured to detect the communication quality of the 5G communication service of the mobile terminal in the first cell. The mobile terminal supports 5G capability in the non-standalone networking (NSA) mode and reports the 5G capability support to the first cell;

[0172] If the communication quality of the 5G communication service is lower than the preset index, perform the abnormality detection of the 5G communication service on the first cell;

[0173] If the 5G communication service of the first cell is abnormal, turn off the 5G capability support of the mobile terminal and report it to the first cell;

[0174] Switch the 5G capability support of the mobile terminal to 4G capability support.

[0175] In the embodiments of the present application, first, the communication quality of the 5G communication service of the mobile terminal accessing the cell is detected. When the communication quality is lower than the preset index, the 5G communication service of the cell is further detected. When the 5G communication service of the cell is abnormal, the support for 5G in the cell is directly stopped and switched to 4G communication. Thus, when the LTE network communication of the NSA anchor cell is abnormal, the specific abnormality of a specific base station can be accurately identified, and the 5G communication of the abnormal cell can be timely switched to the normal 4G communication, avoiding service delay or interruption and improving the stability of the mobile terminal communication service and the user experience.
