[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] The technical solution of the present invention can be applied to various communication systems, such as: Global System of Mobile communication (GSM), Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (Wideband) Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS) system, Long Term Evolution (LTE)/Long Term Evolution-advanced (LTE-A) system, New Wireless (New Radio, NR) system and subsequent evolution communication system, etc.

[0034] The terminal equipment (User Equipment, UE) in the embodiment of the present invention may also be referred to as a mobile terminal (MobileTerminal), mobile user equipment, etc., and may be connected to one or more via a radio access network (for example, Radio Access Network, RAN). A core network for communication. User equipment can be mobile terminals, such as mobile phones (or “cellular” phones) and computers with mobile terminals. For example, they can be portable, pocket-sized, handheld, built-in computers, or vehicle-mounted. Mobile devices, which exchange language and/or data with the wireless access network.

[0035] The network equipment in the embodiment of the present invention is a device deployed in a radio access network device to provide wireless communication functions for terminal equipment. The network equipment may be a base station, for example, and the base station may be an evolved base station (eNB or eNodeB) in LTE. -NodeB, evolutional Node B) and 5G base station (gNB), or subsequent evolved version of the network terminal equipment, the present invention is not limited thereto.

[0036] The technical solutions provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] It should be noted that in the embodiment of the present invention, the mobility state estimation (Mobility State Estimation, MSE) process may have a certain time relationship with the cell reselection process. For example, the MSE is performed before the cell reselection process is initiated, or the MSE is performed when the cell reselection process is initiated, or the MSE is performed at a certain time point after the cell reselection process is initiated. Mobility state evaluation may also be called Mobility State Detection (MSD).

[0038] In the embodiment of the present invention, the MSE process may have no relationship with the cell reselection process, that is, two independent processes. In this case, the cell reselection process just uses the result of the MSE process directly.

[0039] In the embodiment of the present invention, the MSE process may occur after the terminal device reads the system message, and one or more parameters related to the movement state are broadcast in the system message. Or the time point when the MSE process occurs depends on the specific implementation of the terminal device.

[0040] figure 1 The method for evaluating the mobility state according to an embodiment of the present application is shown. Such as figure 1 As shown, the methods include:

[0041] S110: In the process of mobility state assessment MSE, if the cells used to calculate the number of cell reselections in the first assessment period include M private network cells, perform MSE based on the target mode, and M is a positive integer;

[0042] Wherein, the target mode includes one of the following modes:

[0043] Exclude N private network cells among the M private network cells from the MSE process, where N is a positive integer less than or equal to M;

[0044] MSE is performed based on the cells in the second evaluation period, the duration of the second evaluation period is greater than the duration of the first evaluation period; and,

[0045] The first target cell reselection times are determined as the final cell reselection times for the MSE, the first target cell reselection times are greater than the first initial cell reselection times, and the first initial cell reselection times are determined by the The terminal device is calculated based on the cell used for calculating the number of cell reselections.

[0046] The cell used for calculating the number of cell reselections in S110 may include the cell where the terminal device currently resides, or may not include the cell where the terminal device currently resides.

[0047] It is understandable that, in S110, in the case that the terminal equipment used to calculate the number of cell reselections in the first evaluation period includes M private network cells, the terminal equipment is directly based on the target mode during the MSE process. Perform MSE, or the terminal device performs MSE based on the target mode after performing MSE based on the cell used for calculating the number of cell reselections in the first evaluation period.

[0048] It should be noted that in S110, the final number of cell reselections can be understood as the number of cell reselections used to finally evaluate the mobility state (or speed state) of the terminal device and obtain the evaluation result.

[0049] Optionally, in some embodiments, the terminal device performs MSE based on the target mode after calculating the first initial cell reselection times based on the cell used for calculating the cell reselection times.

[0050] Further, if the speed of the terminal device is determined to decrease based on the first initial cell reselection times, after the first initial cell reselection times are calculated based on the cell used to calculate the cell reselection times, MSE is performed based on the target mode.

[0051] In other words, after the terminal device finds that the speed of the evaluation has decreased after an MSE process, it will perform an MSE process again, and perform MSE based on the target method during this MSE process.

[0052] The method for the terminal device to judge the speed reduction of the evaluation can include the following two methods:

[0053] Method 1: If it is determined based on the first initial cell reselection times that the terminal device is in a medium-speed state or a low-speed state, or the first cell reselection times are less than the target threshold, and the terminal device is in a high-speed state before the first initial cell reselection times are calculated , It is determined that the speed of the terminal device is reduced.

[0054] Manner 2: If the first initial cell reselection times are less than the second target cell reselection times, it is determined that the speed of the terminal device is reduced; wherein the second target cell reselection times are used for the time before the first initial cell reselection times are obtained. Evaluate the mobility status of the terminal device during the last MSE.

[0055] In other words, if the evaluation result of the last mobility state evaluation process is high-speed, the evaluation result of this mobility state evaluation process is medium-speed or low-speed, or the number of cell reselections calculated this time is less than the target threshold, it is considered The speed of the terminal device decreases. Or, if the number of cell reselections calculated in the last mobility state evaluation process is X times, and the number of cell reselections calculated in this mobility state evaluation process is less than X times, it is considered that the speed of the terminal device is reduced. In addition, if the evaluation result of the last mobility state evaluation process is a medium-speed state, and the evaluation result of this mobility state evaluation process is a low-speed state, it can also be considered that the speed of the terminal device is reduced.

[0056] The target threshold here can be a numerical value agreed by the protocol, or can be a numerical value configured by the network device.

[0057] Optionally, as an example, in S110, excluding N private network cells among the M private network cells from the MSE process includes:

[0058] The third evaluation period is determined by not counting the staying duration of the N private network cells into the evaluation duration corresponding to the MSE; MSE is performed based on the cells in the third evaluation period.

[0059] For example, suppose the terminal equipment is performing MSE and the evaluation time is T=30s, then the terminal equipment needs to perform statistics on the cell reselection within T (30s) before the current time, but the cells at the current time T include M If there is a private network cell, the terminal device does not count the staying time of the N private network cells in the M private network cells into the evaluation time. In this case, if the sum of the stay durations of the N private network cells is T1, the terminal device can perform MSE based on the cells in T+T1 before the current moment.

[0060] Specifically, performing MSE based on cells in the third evaluation period may be determining the number of cell reselections calculated based on the cells in the third evaluation period as the final number of cell reselections for MSE. Alternatively, the difference between the number of cell reselections calculated based on the cells in the third evaluation period and N is determined as the final number of cell reselections for MSE.

[0061] For example, assuming that the terminal equipment is performing MSE, the evaluation time is T=30s, then the terminal equipment needs to count the number of cell reselections within T (30s) before the current time, and among the cells within T (30s) before the current time Including M private network communities. If the count is K times, and the speed of the terminal device is judged to decrease based on K, the terminal device performs MSE again, and in the process of performing MSE again, exclude N private network cells out of the M private network cells from the MSE process Outside. In this case, if the total stay time of the N private network cells is T1, the terminal equipment will count the number of cell reselections within T+T1 before the current moment. The statistical result is L times, and the terminal equipment will LN is used as the final cell reselection times for MSE.

[0062] Optionally, as an example, the target mode in S110 includes performing MSE based on a cell in the second evaluation period, figure 1 The method shown also includes:

[0063] Determine the second evaluation period based on the duration and duration offset of the first evaluation period;

[0064] Wherein, the duration of the second evaluation period is the sum of the duration of the first evaluation period and the duration offset, and the duration offset is related to at least one of the value of N and the stay duration of the N private network cells.

[0065] That is to say, in the case where the cells used to calculate the number of cell reselections in the first evaluation period include private network cells, the terminal device can directly perform MSE based on the cells in the new evaluation period (the second evaluation period). Or in the case of calculating the first initial cell reselection times based on the cell used to calculate the number of cell reselections in the first evaluation period, and the speed reduction of the terminal device is determined according to the first cell reselection times, based on the new evaluation period Of the cell for MSE. The second evaluation period here may be determined by the duration of the first evaluation period plus a duration offset, and this duration offset is related to at least one of the value of N and the stay duration of the N private network cells. For example, the duration offset is the sum of the stay duration of N private network cells.

[0066] It is understandable that the duration of the second evaluation period may also be a duration agreed by the protocol, or may also be a duration configured by the network device. The relationship between the duration offset and the value of N and at least one of the staying duration of the N private network cells can be agreed through an agreement, or the network device can configure the duration offset and the value of N and the value of N private network cells. The relationship between at least one of the durations of residence.

[0067] Further, performing MSE based on the cells in the second evaluation period includes:

[0068] The second initial cell reselection times are calculated based on the cells in the second evaluation period;

[0069] The sum of the second initial cell reselection times and the first numerical offset is determined as the final cell reselection times for MSE, the first numerical offset and the value of N and the residence time of the N private network cells At least one is relevant.

[0070] For example, if the second initial cell reselection times calculated based on the cells in the second evaluation period is K, then K+N is used as the final cell reselection times for the MSE.

[0071] The relationship between the first numerical offset and the value of N and at least one of the residence time lengths of the N private network cells can be agreed upon by agreement, or the first numerical offset and the value of N and N can be configured through the network device The relationship between at least one of the camping durations of the private network cells.

[0072] Optionally, as an example, the target mode in S110 includes determining the first target cell reselection times as the final cell reselection times for MSE, figure 1 The method shown also includes:

[0073] The sum of the first initial cell reselection times and the second numerical offset is determined as the first target cell reselection times, the second numerical offset and the value of N and the N private network cells At least one of the durations of stay is relevant.

[0074] That is to say, in the case that the number of cells used to calculate the number of cell reselections within the first evaluation period of the terminal device includes private network cells, the first target cell reselection number can be directly determined as the final cell reselection for MSE Or when the first initial cell reselection times are calculated based on the cell used to calculate the cell reselection times in the first evaluation period, and the speed of the terminal device is determined to decrease according to the first cell reselection times, the first target The number of cell reselections is determined as the final number of cell reselections for MSE. The first target cell reselection times here may be determined by the first initial cell reselection times plus a second numerical offset, the second numerical offset and at least one of the value of N and the stay duration of the N private network cells Related. For example, the second value offset is N.

[0075] It is understandable that the number of reselections of the first target cell may also be a value agreed by the protocol, or may also be a value configured by the network device. The relationship between the second numerical offset and the value of N and at least one of the staying durations of the N private network cells can be agreed upon by agreement, or the second numerical offset and the value of N and N can be configured through the network device The relationship between at least one of the camping durations of the private network cells.

[0076] in figure 1 In the method shown, the terminal equipment can determine whether a cell is a private network cell in the following ways:

[0077] Method 1: The terminal device receives the broadcast information of the cell, and the broadcast information contains the indication information that the cell is a private network cell, and then determines that the cell is a private network cell.

[0078] Method 2: The terminal device receives the broadcast information of the cell, and the broadcast information contains frequency and/or physical cell identifier (Physical Cell Identifier, PCI) information. The frequency and/or PCI information is the same as that previously received in other cells. If the identification information of one or more neighboring private network cells in the broadcast information matches (for example, the same), it is determined that the cell is a private network cell.

[0079] Through the above figure 1 The detailed description of the method can be seen, figure 1 In the method shown, the terminal device traces back the evaluation duration based on the evaluation duration, and performs MSE based on the target mode when the cells used for calculating the number of cell reselections within the evaluation duration include private network cells. therefore figure 1 The method described can be referred to as a "retrospective evaluation" method.

[0080] The following will combine figure 2 The method of mobility state assessment according to another embodiment of the present application is described in detail. figure 2 The method shown is executed by the terminal device, such as figure 2 The methods shown include:

[0081] S210: In the process of evaluating the MSE of the mobility state, the private network cell reselected during the evaluation period is excluded from the MSE process, and the start time of the evaluation period is the start time of the MSE process.

[0082] In the method for evaluating the mobility state of the embodiment of the present invention, by excluding the private network cells reselected during the evaluation period from the MSE process, the calculated number of cell reselections can be increased, and unnecessary terminal equipment can be avoided. The choice of resident network results in unnecessary power consumption and reduces the possibility of network congestion.

[0083] Optionally, in S210, in the process of mobility state assessment MSE, the private network cell reselected during the assessment period is excluded from the MSE process, including: if it is in a high-speed state and resides in a private network cell , In the MSE process, the private network cells reselected during the evaluation period are excluded from the MSE process.

[0084] In other words, if the terminal device residing in the private network cell is evaluated as a high-speed state, the terminal device will exclude all reselected private network cells from the MSE process in the next MSE process.

[0085] Optionally, in some embodiments, the excluding the private network cells reselected during the evaluation period from the MSE process includes: not counting the number of cell reselections during the evaluation period. The reselected private network cell; the camping time of the reselected private network cell is not included in the evaluation duration of the evaluation period.

[0086] For example, suppose that the terminal device in the private network cell is in a high-speed state through the result of the first MSE process, and then the terminal device is based on some conditions (for example, the terminal device reads a system message, and the system message broadcasts a mobile state related One or more parameters of) will start the second MSE process with an evaluation duration of 30s. Then, if the subsequent reselection is a private network cell, the number of cell reselections will not be counted, and the residence time in the private network cell will not be counted into the evaluation time. For example, if the evaluation time is 30s, when the terminal equipment counts 10 times of cell reselection and the evaluation time has passed 20s, the terminal equipment reselects to private network cell A and stays in private network cell A for 3s, then the terminal The device still considers that the number of cell reselections is 10 and the evaluation duration has passed 20s. After that, if the terminal device reselects to public network cell B and stays in public network cell B for 10s, the terminal device considers the final cell of this evaluation The number of reselections is 11 times. In other words, it can be considered that the actual evaluation time used by the terminal equipment is 23s, and the private network cell A is not counted.

[0087] in figure 2 In the method shown, the terminal equipment can determine whether a cell is a private network cell in the following ways:

[0088] Method 1: The terminal device receives the broadcast information of the cell, and the broadcast information contains the indication information that the cell is a private network cell, and then determines that the cell is a private network cell.

[0089] Method 2: The terminal device receives the broadcast information of the cell, and the broadcast information contains frequency and/or physical cell identifier (Physical Cell Identifier, PCI) information. The frequency and/or PCI information is the same as that previously received in other cells. If the identification information of one or more neighboring private network cells in the broadcast information matches (for example, the same), it is determined that the cell is a private network cell.
