Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to a method, device, storage medium and electronic equipment for monitoring a wireless link state. Background Art

[0002] In the process of continuous evolution of wireless communication networks, in order to monitor Radio Link Failure (RLF), the current technology uses the UE physical layer to monitor the downlink radio link quality of the primary cell to indicate the out-of-sync state or in-sync state to the higher layer. When the RRC receives N310 consecutive out-of-sync indications, the UE starts timer T310. Assuming that the UE receives N311 synchronization indication before the timer expires, the T310 timer will stop. If N311 consecutive in-sync instructions are not received during the T310 timer, the RRC connection reestablishment process or the MCG fail information process will generally be triggered for the fast reestablishment process.

[0003] According to the communication protocol, the values ​​of T310, N310, and N311 are determined by the configuration on the network side. If the network side does not carry them, they are determined by the value of ue-TimersAndConstants in SIB1.

[0004] Since the values ​​of T310, N310, and N311 are fixed and the default values ​​are large, the time it takes for the UE to determine whether the radio link fails is long.

[0005] With respect to the problem in the related art that it takes a long time for the UE to determine whether a wireless link has failed, no effective solution has been proposed yet. Summary of the invention

[0025] The method embodiments provided in the embodiments of the present application can be executed in a computer terminal or a similar computing device. Taking running on a computer terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a computer terminal of a method for monitoring a wireless link status according to an embodiment of the present application. Figure 1 As shown, the computer terminal may include one or more ( Figure 1 Only one is shown in the figure) processor 102 (processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data. In an exemplary embodiment, the computer terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned computer terminal. Figure 1 More or fewer components as shown, or with Figure 1 Equivalent functions or comparisons shown Figure 1 A different configuration with more features is shown.

[0026] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the method for monitoring the wireless link status in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the computer terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0027] The transmission device 106 is used to receive or send data via a network.

In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0028] In this embodiment, a method for monitoring the status of a wireless link is provided, which is applied to the above-mentioned computer terminal. Figure 2 : is a flow chart of a method for monitoring a wireless link status according to an embodiment of the present application, the process comprising the following steps:

[0029] S202, determining the mobility status of the user terminal;

[0030] Optionally, the above-mentioned moving state includes one of the following: a normal moving state (normal), a medium-speed moving state (medium), and a high-speed moving state (high).

[0031] S204, determining, according to the mobility state, a first maximum value of the downlink out-of-sync indication continuously received by the user terminal, a second maximum value of the downlink synchronization indication continuously received by the user terminal, and a timer duration for the user terminal to monitor a radio link failure, wherein the radio link is a radio link corresponding to the user terminal;

[0032] It should be noted that the above-mentioned first maximum value can be understood as the value corresponding to N310; the second maximum value can be understood as the value corresponding to N311, and the timer duration can be understood as the value corresponding to T310.

[0033] S206: Determine whether the wireless link fails according to the first maximum value, the second maximum value, and the timer duration.

[0034] Through the above embodiment, the mobility state of the user terminal is determined; according to the mobility state, the first maximum value of the downlink out-of-sync indication continuously received by the user terminal, the second maximum value of the downlink synchronization indication continuously received by the user terminal and the timer duration for the user terminal to monitor the failure of the wireless link are determined, wherein the wireless link is the wireless link corresponding to the user terminal; according to the first maximum value, the second maximum value and the timer duration, it is determined whether the wireless link fails. In the embodiment of the present invention, the first maximum value, the second maximum value and the timer duration can be flexibly determined according to the mobility state of the user terminal, thereby reducing the time duration for determining whether the wireless link fails, thereby solving the technical problem in the related art that the UE takes a long time to determine whether the wireless link fails.

[0035] Optionally, since the moving state includes one of the following: a normal moving state (normal), a medium moving state (medium), and a high moving state (high), in different moving states, the above step S204 can be implemented in the following manner:

[0036] 1) when the moving state is a normal moving state, determining that the first value is the first maximum value, the second value is the second maximum value, and the preset timer duration is the timer duration, wherein the first value is the preset value of the first maximum value, and the second value is the preset value of the second maximum value;

[0037] It is understandable that, when the mobile state is a normal mobile state, the first maximum value, the second maximum value, and the timer duration are directly determined according to the preset values. For example, the first maximum value, the second maximum value, and the timer duration are determined according to data such as N310, N311, and T310 sent by the network side.

[0038] 2) when the moving state is a medium-speed moving state, determining a first maximum value according to the product of the first value and the first scaling factor, determining a second maximum value according to the product of the second value and the first scaling factor, and determining the timer duration according to the product of a preset timer duration and the first scaling factor;

[0039] It can be understood that, when the moving state is a medium-speed moving state, the first maximum value, the second maximum value, and the timer duration are determined according to the determined first scaling factor. Specifically, the first product of the first value and the first scaling factor is determined, and the first product is rounded up, and the result of the rounding up is used as the first maximum value; the second product of the second value and the first scaling factor is determined, and the second product is rounded up, and the result of the rounding up is used as the second maximum value; the third product of the preset timer duration and the first scaling factor is determined, and the third product is used as the timer duration.

[0040] Optionally, the first scaling factor may be determined by one of the following methods:

[0041] 1. sf1 = 1 / 2 N+1 , where N represents the first number of user terminals accessing the cell within the target time period, and sf1 represents the first scaling factor.

[0042] 2. Use a fixed value as the first scaling factor, such as 0.25.

[0043] For example, when the first scaling factor is 0.25, the first maximum value The second largest value Timing duration T310 actual =T311×0.25, symbol Indicates rounding up, where N310 represents the first value and N311 represents the second value.

[0044] 3) When the moving state is a high-speed moving state, a first maximum value is determined according to the product of the first value and the second scaling factor, a second maximum value is determined according to the product of the second value and the second scaling factor, and the timer duration is determined according to the product of a preset timer duration and the second scaling factor, wherein the first scaling factor is greater than the second scaling factor.

[0045] It can be understood that, when the moving state is a high-speed moving state, the first maximum value, the second maximum value, and the timer duration are determined according to the determined second scaling factor. Specifically, the fourth product of the first value and the second scaling factor is determined, and the fourth product is rounded up, and the result of the rounding up is used as the second maximum value; the fifth product of the second value and the second scaling factor is determined, and the fifth product is rounded up, and the result of the rounding up is used as the second maximum value; the sixth product of the preset timer duration and the second scaling factor is determined, and the sixth product is used as the timer duration.

[0046] Optionally, the first scaling factor sf2 may be determined by the following formula: sf2=1 / 2 N+1 , where N represents the first number of user terminals accessing the cell within the target time period.

[0047] It should be noted that the possibility of failure of the UE's wireless link is greater in the high-speed mobile state than in the medium-speed mobile state. Therefore, the second scaling factor is smaller than the first scaling factor, which can further shorten the time for determining whether the UE's wireless link has failed, solving the technical problem in the related technology that the UE takes a long time to determine whether the wireless link has failed.

[0048] It should be noted that the values ​​of the first scaling factor and the second scaling factor are less than 1.

[0049] Optionally, the above step S204 may also be determined by the following steps:

[0050] Step 1: determining the link quality of the wireless link and the task load parameter of the user terminal;

[0051] Step 2: Determine the first maximum value, the second maximum value and the timer duration according to the mobility state, the link quality and the task load parameter.

[0052] Specifically, a third scaling factor is determined according to the mobility state, link quality and the task load parameter; the first maximum value is determined according to the product of the first value and the third scaling factor, the second maximum value is determined according to the product of the second value and the third scaling factor, and the timer duration is determined according to the product of a preset timer duration and the third scaling factor, wherein the first value is a preset value of the first maximum value, and the second value is a preset value of the second maximum value.

[0053] It can be understood that the third scaling factor in the embodiment of the present invention is determined based on three parameters: mobility state, link quality and the task load parameter, and then the first maximum value, the second maximum value and the timer duration are determined based on the third scaling factor.

[0054] Optionally, determining a third scaling factor sf3 according to the mobile state, link quality and the task load parameter includes: when the mobile state is a normal mobile state, sf3=a1L+a2Y; when the mobile state is a medium-speed mobile state, sf3=1 / 2 N+1 +a1L+a2Y; when the moving state is a high-speed moving state, sf3=1 / 2 N+1+a3L+a4Y; wherein N represents the first number of user terminals accessing the cell within the target time period, L represents the link quality, Y represents the task load parameter, a1 and a3 represent the weights of the link quality, and a2 and a4 represent the weights of the task load parameter.

[0055] In an exemplary embodiment, determining the mobility state of a user terminal includes: determining a first number of cells accessed by the user terminal within a target time period; when the first number is not greater than a third value, determining that the mobility state of the user terminal is a normal mobility state; when the first number is greater than the third value and less than or equal to a fourth value, determining that the mobility state of the user terminal is a medium-speed mobility state; when the first number is greater than the fourth value, determining that the mobility state of the user terminal is a high-speed mobility state.

[0056] For example, the number of switching times N=0 within the target time period of 10s indicates a normal moving state, N=1 indicates a medium-speed moving state, and N>=2 indicates a high-speed moving state.

[0057] Optionally, the above-mentioned step S206 can be implemented in the following manner: determine the second number of downlink out-of-sync indications continuously received by the user terminal; when the second number is equal to the first maximum value, start the timer and determine the third number of downlink synchronization indications continuously received within the timer duration corresponding to the timer; when the third number reaches the second maximum value, determine that the wireless link has not failed; when the third number does not reach the second maximum value, determine that the wireless link has failed.

[0058] It should be noted that the third number reaching the second maximum value can be understood as: the third number is greater than or equal to the second maximum value; the third number not reaching the second maximum value can be understood as: the third number is less than the second maximum value.

[0059] It is understandable that when receiving the out-of-sync indication of the first maximum value sent by the physical layer, the timer is started. During the operation of the timer, if the in-sync indication of the second maximum value is received continuously, the UE stops the timer and determines that the radio link has not failed. If the in-sync instruction of the second maximum value is not received continuously during the T310 timer, it is determined that the radio link has failed, thereby triggering the RRC connection reconstruction process or the MCG failinformation process.

[0060] In order to better understand the process of the above-mentioned wireless link status monitoring method, the implementation method flow of the above-mentioned wireless link status monitoring is described below in combination with an optional embodiment, but it is not used to limit the technical solution of the embodiment of the present application.

[0061] The moving speed of the UE is expressed as normal, medium, and high, and its purpose is to determine the mobility state of the UE. The embodiment of the present invention provides a monitoring method for determining data such as N310, N311, and T310 according to the moving speed of the UE, and then determining the wireless link state according to the data such as N310, N311, and T310; Figure 3 As shown, the specific steps are as follows:

[0062] Step S301: Determine the number of times N that the UE switches cells within a period of time;

[0063] Step S302: determining the mobility state of the UE in the connected state according to the number of cell switching times N;

[0064] For example, the number of switching times within a certain period of time 10s N=0 is a normal speed state (equivalent to the normal moving state in the above embodiment), N=1 is a medium speed state (equivalent to the medium speed moving state in the above embodiment), and N>=2 is a high speed state (equivalent to the high speed moving state in the above embodiment).

[0065] Step S303: Determine the values ​​corresponding to data such as N310, N311, and T310 according to the mobility state of the UE in the connected state;

[0066] Specifically, if the number of handovers in the last 10 seconds is 0, the UE is considered to be in the normal speed state and uses the N310, N311, T310 and other data sent by the network side normally. If the number of handovers in the last 10 seconds is 1, the UE is considered to be in the medium speed state, and the scaling factor sf can be preset to 0.25. If the number of handovers in the last 10 seconds is >= 2, the UE is considered to be in the high speed state, and the scaling factor sf can be specified as 1 / 2. N+1 , that is, when N = 2, the scaling factor is 0.125. Correspondingly, T310 actual =T311×sf, symbol Meaning round up. N310 actual (equivalent to the first maximum value in the above embodiment), N311 actual (equivalent to the second maximum value in the above embodiment), T311 actual (equivalent to the third maximum value in the above embodiment) is the data actually taken by the UE, such as N310 (equivalent to the first value in the above embodiment), N311 (equivalent to the second value in the above embodiment), T310 (equivalent to the preset timing duration in the above embodiment), etc.

[0067] Step S304: determining whether the wireless link fails according to the determined values ​​corresponding to N310, N311, and T310;

[0068] For example, if the UE switches twice within 10 seconds, the UE is in the high speed state. If out-of-sync occurs at this time, then, T310 actual =4×0.125=0.5. It takes 0.54s from the occurrence of out-of-sync to the timeout of T310.

[0069] If the network side sets T310 to 4s, n310 to n10, and n311 to n5, it will take at least 4.4s from the time the physical layer detects out-of-sync to the time the T310 timer times out. Therefore, compared with the original triggering of RadioLinkFailure, the embodiment of the present invention saves 3.86s in overall time consumption, and has a significant effect in reducing the offline time.

[0070] The above is to speed up the out-of-sync processing process by adjusting the physical layer reporting out-of-sync / in-sync and the T310 period triggered by the mobility state; similarly, in the mobile state, the link failure caused by but not limited to the number of RLC retransmissions, the number of attempts to re-access the network after the link is lost, and the T300 timer, etc., which can be adjusted by mobility. Related parameters related to the timer and the number of attempts can also be adjusted according to the mobility state of the device.

[0071] Similarly, the number of adjustments and timer-related parameters based on mobility are not limited to the method proposed in this article, and alternative functions such as inverse proportional functions and geometric functions can also be used; the selected parameters are not limited to the number of switching input parameters, and multiple parameter combinations can be used simultaneously, including but not limited to UE link quality, UE task load and other parameters, to jointly determine the scaling factor to characterize the impact between speed and parameters.

[0072] In addition, the speed determination method is not limited to the number of mobile switching times N. The present invention only uses this as an example. Similarly, the UE can customize how to determine its own mobility, such as through hardware devices, or positioning systems such as GPS, or determine its own mobility based on changes in UE link quality in a short period of time.

[0073] Through the embodiments of the present invention, for terminals in a connected state, the time from link failure to link recovery can be effectively reduced, the user offline time caused by physical layer desynchronization can be effectively reduced, and measures such as RRC reconstruction and other network recovery measures can be performed more quickly, effectively improving the user experience in mobile scenarios.

[0074] It should be noted that, for the above-mentioned method embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should know that the present invention is not limited by the described action sequence, because according to the present invention, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present invention.

[0075] According to another aspect of the embodiments of the present invention, a wireless link status monitoring device for implementing the wireless link status monitoring method is also provided. Figure 4 As shown, Figure 4 is a schematic structural diagram of an optional wireless link status monitoring device according to an embodiment of the present invention, the device comprising:

[0076] A first determining module 42, configured to determine a mobile state of a user terminal;

[0077] A second determination module 44 is used to determine, according to the mobility state, a first maximum value of the downlink out-of-sync indication continuously received by the user terminal, a second maximum value of the downlink synchronization indication continuously received by the user terminal, and a timer duration for the user terminal to monitor a radio link failure, wherein the radio link is a radio link corresponding to the user terminal;

[0078] The third determination module 46 is used to determine whether the wireless link fails according to the first maximum value, the second maximum value and the timer duration.

[0079] Through the above-mentioned device, the mobile state of the user terminal is determined; according to the mobile state, the first maximum value of the downlink out-of-sync indication continuously received by the user terminal, the second maximum value of the downlink synchronization indication continuously received by the user terminal and the timer duration for the user terminal to monitor the failure of the wireless link are determined, wherein the wireless link is the wireless link corresponding to the user terminal; according to the first maximum value, the second maximum value and the timer duration, it is determined whether the wireless link fails. In the embodiment of the present invention, the first maximum value, the second maximum value and the timer duration can be flexibly determined according to the mobile state of the user terminal, thereby reducing the time duration for determining whether the wireless link fails, thereby solving the technical problem in the related art that the UE takes a long time to determine whether the wireless link fails.
