In the following, with reference to FIG. 4, the terminal 101 shown in FIG. 1 is used as the executive body to describe the method for determining the mobile state of the terminal provided by the embodiment of the present application:

S101: The terminal 101 reselects from the first cell to the second cell, where the first cell is a cell of the first RAT, and the second cell is a cell of the second RAT. In implementation, the first RAT and the second RAT may be 2G/3G RAT, 4G RAT, 5G RAT, or one of future mobile access technologies, respectively, and the first RAT and the second RAT are different RATs. The second cell may be the first cell that the terminal 101 reselects to the second RAT.

S102: The terminal 101 retains first information, which is used to determine the mobile state of the terminal 101 after reselecting to the second cell, and the first information is related to the mobile state of the terminal 101 before reselecting to the second cell, or, The first information is related to information used to determine the mobile state of the terminal 101 before reselecting to the second cell.

Using the above method, after the terminal 101 reselects to the second cell through the inter-system cell reselection process, the above first information is retained, and the mobile state of the terminal 101 after reselecting to the second cell is determined according to the first information. 101 does not need to re-collect the information needed to determine the movement status, so that the movement status can be determined quickly and reasonably.

In the steps involved in S102, the first information is related to the mobile state of the terminal 101 before reselecting to the second cell, which means that the first information includes information for indicating the mobile state of the terminal 101 before reselecting to the second cell, or , Means that the first information is used to indicate the moving state. Among them, the value of the bit can be used to indicate the mobile state of the terminal 101 before reselecting to the second cell. For example, when the value of two consecutive bits is "00", it means that the mobile state of the terminal 101 before reselecting to the second cell is high-speed movement; when the value of the two consecutive bits is " 01", it means that the mobile state of the terminal 101 before reselecting to the second cell is the medium-speed moving state; when the value of the two consecutive bits is "11", it means that the terminal 101 is reselecting to the second cell. The previous mobile state of the cell is the normal mobile state. For another example, the information stored before the terminal 101 is reselected to the second cell to indicate the movement status, such as the movement status information stored in a specific location of the terminal 101, can be used as the first information, which indicates that the terminal 101 is moving at a high speed. State, medium-speed moving state or normal moving state.

In addition, the first information is related to the information used to determine the mobile state of the terminal 101 before reselecting to the second cell, which means that the first information includes information used to determine the mobile state of the terminal 101 before reselecting to the second cell. The state information, or, refers to the first information used to determine the above-mentioned information used to determine the mobile state of the terminal 101 before reselecting to the second cell. Wherein, the above information used to determine the mobile state of the terminal 101 before reselecting to the second cell may include information about one or more reselected cells of the terminal 101 before reselecting to the second cell, the one or more The information of each reselected cell can be used to determine the mobile state of the terminal 101 before reselecting to the second cell. For example, the information of one or more reselected cells can be used to determine the number of cell reselections performed by the terminal 101 in a period of time before reselecting to the second cell, and the number of times can be used to determine the mobile state of the terminal 101. The above first information may include information about one or more reselected cells, and may also be used to indicate information about the one or more reselected cells. In addition, the first information may also include other information that can be used to determine the mobile state of the terminal 101 before reselecting to the second cell, for example, including the number of cell reselections performed by the terminal 101 within a period of time and/or Information and other content of the cell. The related information can also be used to determine the number of cell reselections performed by the terminal 101 in a period of time before reselecting to the second cell, so that it can be used to determine the mobile state of the terminal 101. The information used to determine the mobile state of the terminal 101 before reselecting to the second cell may also include the information before the terminal 101 reselected to the second cell, when it reselected to the second cell, or reselected to the second cell Then the value of the hysteresis timer corresponding to the first RAT.

In a possible implementation manner, the first information may include information of one or more reselected cells before the terminal 101 reselects to the second cell, and the information of the one or more reselected cells is used to determine the reselection to The previous movement state of the second cell. The one or more reselected cells mentioned here refer to the cells reselected by the terminal 101 before reselecting to the second cell. For example, before S101, the terminal 101 also reselects from the third cell to the first cell, and the above one or more reselected cells include the first cell and the third cell involved in S101. For another example, the terminal 101 in the above example also reselects from the fourth cell to the third cell, and the one or more reselected cells described here also include the fourth cell.

If the first information includes the information of the above one or more reselection cells, after the step shown in S102, the terminal 101 may also use the information of the above one or more reselection cells, the information of the second cell, or the information in the first parameter Part or all of the information to determine the mobile state of the terminal 101 after reselecting to the second cell, where the first parameter is a parameter related to the mobile state of the second cell (or, the first parameter is a mobile state-related parameter).

The above-mentioned information of one or more reselected cells includes at least one of the identification (ID), frequency band, frequency, subcarrier interval, cell reselection time, or frequency point information of each reselected cell. Wherein, the cell reselection time of the reselection cell may include the time interval between the terminal 101 reselecting to the previous serving cell of the cell and reselecting to the cell, or the terminal 101 reselecting to the cell and reselecting to the cell. The time interval between the next serving cells of the cell, or part or all of the time when the terminal 101 reselects to the cell.

In addition, the above information of the second cell includes at least one of the ID, frequency band, frequency, subcarrier spacing, cell reselection time, or frequency point information of the second cell. Wherein, the cell reselection time corresponding to the second cell may include the time interval between the terminal 101 reselecting to the previous serving cell of the second cell (ie, the first cell) and the reselection to the second cell, and the terminal 101 reselecting The time interval between the selection of the second cell and the next serving cell reselected to the second cell, or part or all of the time when the terminal 101 reselects to the second cell.

Exemplarily, the terminal 101 may receive the broadcast of the second cell to obtain the first parameter mentioned above. The first parameter may comprise at least one parameter _{_T} _CRmax, N CR_H, N CR_M _T CRmaxHyst or the like. Among them, T _CRmax can be used to instruct the terminal 101 to determine the duration of the number of cell reselections. N _{CR_H} can be used to indicate the number of cell _reselections that need to be exceeded within T _CRmax that the terminal 101 determines to enter the high mobility state. N _{CR_M} can be used to indicate the number of cell _reselections that need to be reached within T _CRmax to determine the number of cell _reselections required to enter the moving state. T _CRmaxHyst can be used to indicate the extra time required to determine the normal movement state.

For example, after the terminal 101 reselects to the second cell, the information of the above one or more reselected cells (or the information of some or all of the one or more reselected cells), the information of the second cell the method of the first information and the movement state parameter determined as follows: determining a first terminal 101 parameters _{_T} _CRmax, N CR_H, N CR_M and _T CRmaxHyst, in conjunction with one or more information than the cell reselection information and a second cell , Determine the _number of cell reselections performed by the terminal 101 within the duration of T _CRmax . If the number is greater than N _{CR_H} broadcast by the second cell, the terminal 101 determines that the mobile state is a high-speed mobile state; if the number is greater than or equal to the number broadcast by the second cell If N _{CR_M is} less than or equal to N _{CR_H} , the terminal 101 determines that the mobile state is a medium-speed mobile state; if the number of times is less than N _{CR_M} broadcast by the second cell, the terminal 101 continues to determine whether the aforementioned entry into the high-speed mobile state or the medium-speed mobile state is satisfied If the conditions for entering the high-speed movement state and the medium-speed movement state are not met within the duration of T _CRmaxHyst , the terminal can determine that its movement state is the normal movement state.

In another feasible implementation manner, the first information involved in S102 can be used to indicate the mobile state of the terminal 101 before reselecting to the second cell, and the terminal 101 can reselect the terminal 101 after reselecting to the second cell The mobile state before the second cell is determined to be the mobile state after the terminal 101 reselects to the second cell. Therefore, with this implementation method, after the terminal 101 reselects from the cell of the first RAT to the cell of the second RAT, the mobile state of the terminal 101 when it is in the cell of the first RAT can be used as the state after reselecting to the cell of the second RAT. The mobile state of the second RAT can be quickly and reasonably determined.

After determining the moving state after reselecting to the second cell, the terminal 101 may also adjust the value of the reselection timer of the terminal 101 according to the moving state. Specifically, when the terminal 101 is in a high-speed moving state, the terminal 101 multiplies the value of the _reselection timer (T _{reselectionRAT} ) by the parameter sf-High, and uses the calculation result as the value of the adjusted reselection timer. When the terminal 101 is moving at a medium speed, the terminal 101 multiplies the value of the reselection timer by the parameter sf-Medium, and uses the calculation result as the value of the adjusted reselection timer.

In addition, the terminal 101 can also adjust the value of the hysteresis parameter Qhyst according to the moving state. Specifically, when the terminal 101 is moving at a high speed, the parameter sf-High may be added to Qhyst, and the calculation result may be used as the adjusted Qhyst. When the terminal 101 is moving at a medium speed, sf-Medium can be added to Qhyst, and the calculation result can be used as the adjusted Qhyst.

In the above design, the values of sf-High and sf-Medium are preset or configured by the base station. For example, sf-High and/or sf-Medium are broadcast by the current serving cell in the form of system information. With the above design, when the mobile state is high-speed or medium-speed mobile state, the timing duration of the reselection timer can be shortened, and the hysteresis parameter Qhyst can be reduced, so as to increase the frequency of terminal reselection, so that the UE can reselect to high quality as soon as possible Of the cell.

After the terminal 101 reselects to the second cell, the terminal 101 can also set the second cell after the terminal 101 reselects to the second cell according to the parameter T _CRmaxHyst broadcast by the second cell and the count value of the hysteresis timer corresponding to the first RAT. The count value of the hysteresis timer corresponding to the RAT. The count value of the hysteresis timer corresponding to the first RAT may be the count value of the hysteresis timer corresponding to the first RAT before the terminal 101 reselects to the second cell, and the time when the terminal 101 reselects to the second cell is first The count value of the hysteresis timer corresponding to the RAT, or the count value of the hysteresis timer corresponding to the first RAT after the terminal 101 reselects the second cell. It should be understood that the above first information may also include the value of the hysteresis timer corresponding to the first RAT.

Specifically, when the terminal 101 determines that the count value of the hysteresis timer corresponding to the first RAT is not less than T _CRmaxHyst , the terminal 101 may set the count value of the hysteresis timer corresponding to the second RAT to T _CRmaxHyst .

In addition, when the terminal 101 determines that the count value of the hysteresis timer corresponding to the first RAT is less than T _CRmaxHyst , the terminal 101 may set the count value of the hysteresis timer corresponding to the second RAT to the count value of the hysteresis timer corresponding to the first RAT .

For example, suppose that the terminal 101 moves in the normal state after reselecting from the NR cell (that is, the cell of the first RAT) to a certain LTE cell (that is, the cell of the second RAT). In addition, assume that the T _CRmaxHyst is 240 seconds (s). Before, during or after reselecting from the NR cell to the LTE cell, the count value of the hysteresis timer of the terminal 101 is 230s (that is, the count value of the hysteresis timer corresponding to the first RAT is 230s) , If the terminal 101 inherits the count value of the hysteresis timer after reselecting the LTE cell, that is, the count value of the hysteresis timer for the second RAT is set to 230s, then the terminal 101 will apply the corresponding value of the normal movement state after 10s Cell reselection method. However, if it is not inherited, that is, the count value of the hysteresis timer after reselecting to the LTE cell returns to 0, the terminal 101 still needs to wait 240s to perform cell reselection. The terminal 101 needs to apply the cell reselection method corresponding to the high-speed state (speed scaling factor is 0.25 to 1) within the 240s (230s more than the inherited). Compared with the normal speed, the high speed needs to be carried out at most at the same time (230s) 4 times the cell reselection, considering that 230s is much longer than the next cell reselection at normal speed (in seconds), so if the terminal 101 reselects from the NR cell to the LTE cell, the hysteresis timer is not inherited The count value will significantly increase the power consumption.

In addition, if it is assumed that the T _CRmaxHyst broadcast by the LTE cell is 180s, that is, the maximum value of the hysteresis timer is 180s, before, during or after reselecting from the NR cell to the LTE cell, if the count value of the hysteresis timer of the terminal 101 If it is 230s, in order to prevent the terminal from inheriting the count value of the hysteresis timer and cause the timer to count errors, the count value of the hysteresis timer after reselecting to the LTE cell can be set to 180s.

As shown in FIG. 5, the terminal 101 shown in FIG. 1 is still used as the execution body to illustrate the specific process of the method for determining the mobile state of the terminal provided by the embodiment of the present application:

S201: The terminal 101 reselects from the first cell to the second cell, where the first cell is a cell of the first RAT, and the second cell is a cell of the second RAT. In implementation, the first RAT and the second RAT may be GSM, UTRAN FDD/TDD, GERAN, CDMA2000, EUTRAN, NR, or one of future mobile access technologies, respectively, and the first RAT and the second RAT are different RAT. The second cell may be the first cell that the terminal 101 reselects to the second RAT.

S202: The terminal 101 retains the first information. The first information includes the information of one or more reselected cells before the terminal 101 reselects to the second cell. The information of the one or more reselected cells is used to determine the reselection to the second cell. Describe the previous movement state of the second cell.

S203: The terminal 101 determines the movement state of the terminal 101 after reselecting to the second cell according to the first information, the information of the second cell, and the movement state related parameters of the second cell broadcast by the second cell. After the terminal 101 determines the moving state after reselecting to the second cell, the terminal 101 may perform subsequent cell reselection according to the moving state.

After the terminal 101 reselects to the second cell under the second RAT, if it does not retain the information of the reselected cell before reselecting to the second cell, the terminal 101 can only use the current information of the second cell and the information of the second cell. The movement state parameter determines the current movement state, and the judgment result is not accurate. For example, if the terminal 101 is in a high-speed moving state before moving to the second cell, after reselecting to the second cell, since the information of the reselected cell before reselecting to the second cell is cleared, the previous terminal 101 cannot be counted. For the number of reselections, the terminal 101 is likely to enter a medium-speed moving state or a normal moving state at this time, resulting in the terminal being unable to perform cell reselection according to the high-speed moving state. At this time, the following problems may occur: First, the terminal is barred from accessing (bar) when it receives a paging in a non-resident cell (because it moves too fast without time to reselect). Second, the terminal has not had time to update the registration area when it crosses the registration area, causing the page to be lost. Third, for the terminal equipment in the V2X system, when the terminal requests a service with high QoS requirements through a sidelink, it is difficult to establish a connection to request mode 1 resources. Fourth, it is difficult for a terminal in an idle state or an inactive state to read the mode 2 resources broadcast by the current cell, and it is difficult to guarantee the QoS requirements using the original mode 2 resources of the cell before reselection.

If the process shown in Figure 5 above is adopted, the terminal 101 still retains the information of the reselected cell before reselecting to the second cell, so that the information of the second cell and the mobility status parameters of the second cell can be combined to determine the current mobility state, and avoid The emergence of the above problems. For example, in the above example, if combined with the information of the reselected cell before reselecting to the second cell, the terminal 101 may determine to enter a high-speed moving state, thereby reselecting to a high-quality cell faster, and avoiding any impact on the quality of service. influences.

As shown in FIG. 6, the terminal 101 shown in FIG. 1 is still used as the executive body to illustrate the specific process of the method for determining the mobile state of the terminal provided by the embodiment of the present application:

S301: The terminal 101 reselects from the first cell to the second cell, where the first cell is a cell of the first RAT, and the second cell is a cell of the second RAT. In implementation, the first RAT and the second RAT may be 2G/3G RAT, 4G RAT, 5G RAT, or one of future mobile access technologies, respectively, and the first RAT and the second RAT are different RATs. The second cell may be the first cell that the terminal 101 reselects to the second RAT.

S302: The terminal 101 retains the first information, which is used to indicate the mobile state of the terminal 101 before reselecting to the second cell.

S303: The terminal 101 determines the mobile state before reselecting to the second cell as the mobile state after the terminal 101 reselects to the second cell. After the terminal 101 determines the moving state after reselecting to the second cell, the terminal 101 may perform subsequent cell reselection according to the moving state.

It should be understood that after the steps shown in S203 and S303 above, the terminal 101 can also adjust the reselection timer of the terminal 101 according to the mobile state of the terminal 101 after reselecting to the second cell according to the method provided in the embodiment of the present application. Value and/or the value of the hysteresis parameter Qhyst. For specific methods, please refer to the foregoing introduction, which will not be repeated here.

Using the process shown in FIG. 6 above, the terminal 101 still retains the mobile state before reselecting to the second cell after reselecting to the second cell, thereby avoiding the impact of the shift to the mobile state reset on the service quality.

As shown in FIG. 7, the terminal 101 shown in FIG. 1 is still used as the executive body to illustrate the specific process of the method for determining the mobile state of the terminal provided by the embodiment of the present application:

S401: The terminal 101 reselects from the first cell to the second cell, where the first cell is a cell of the first RAT, and the second cell is a cell of the second RAT. In implementation, the first RAT and the second RAT may be 2G/3G RAT, 4G RAT, 5G RAT, or one of future mobile access technologies, respectively, and the first RAT and the second RAT are different RATs. The second cell may be the first cell that the terminal 101 reselects to the second RAT.

S402: The terminal 101 sets the hysteresis timer corresponding to the second RAT after the terminal 101 reselects to the second cell according to the parameter T _CRmaxHyst broadcast by the second cell and the hysteresis timer corresponding to the first RAT. Specifically, when the terminal 101 determines that the count value of the hysteresis timer corresponding to the first RAT is not less than T _CRmaxHyst , the terminal 101 may set the count value of the hysteresis timer corresponding to the second RAT to T _CRmaxHyst . Alternatively, when the terminal 101 determines that the count value of the hysteresis timer corresponding to the first RAT is less than T _CRmaxHyst , the count value of the hysteresis timer corresponding to the second RAT is set to the count value of the hysteresis timer corresponding to the first RAT.

It should be understood that the process shown in FIG. 7 above can be used in combination with the process shown in FIG. 5 or FIG. 6. For example, the step shown in S402 may be executed after S202 shown in FIG. 5 or S302 shown in FIG. 6.

In addition, it should be understood that the process shown in Figures 5-7 above is only an example for the terminal 101 to determine the movement status after reselecting to the second cell. This application does not exclude the terminal 101 from reselecting to the second cell. A serving cell, and/or more subsequent cell reselection procedures still retain the above first information, so that after the terminal 101 reselects from the second cell to the next serving cell, the terminal 101 can still use the first information Determine the mobile status.

Exemplarily, if the first information includes the information of one or more reselected cells before the terminal reselects to the second cell, the terminal 101 may still select one or more cells based on the one or more after reselecting from the second cell to the next serving cell. The information of multiple reselected cells determines the movement status. For example, the terminal 101 may determine to reselect to the next mobile state according to at least one of the following information: information of the one or more reselected cells (or some or all of the one or more reselected cells) Information), information of the second cell, information of the next serving cell, or parameters related to the movement status of the next serving cell. In addition, if the first information is used to indicate the mobile state of the terminal before reselecting to the second cell, the terminal 101 can still inherit the mobile state after reselecting from the second cell to the next serving cell. Alternatively, the terminal 101 may determine the mobile state of the terminal 101 in the next serving cell according to at least one of the following information in combination with the method for determining the mobile state provided in this application: the mobile state, the information of the second cell, the next Serving cell information or parameters related to the moving state of the next serving cell.

In the above example, the content of the information of the next serving cell can refer to the description of the information of the second cell in this application. For the content of the parameters related to the movement state of the next serving cell, refer to the description of the first parameter in this application.

As shown in FIG. 8, the method for determining the mobile state of the terminal provided by the embodiment of the present application may include the following steps:

S501: The terminal 101 reselects from the first cell to the second cell. Among them, the first cell is a cell under the first RAT, and the second cell is a cell under the second RAT.

S502: The terminal 101 retains first information, and the first information includes information of one or more reselected cells, and the information of the one or more reselected cells may be used to determine the mobile state of the terminal 101.

The information of one or more reselected cells may include some or all of the following information: the identification ID of the reselected cell, the frequency band of the reselected cell, the frequency of the reselected cell, the subcarrier interval of the reselected cell, and the reselection The cell reselection time of the cell, the frequency of the reselected cell, or the coverage radius of the reselected cell (the coverage radius of the reselected cell can be the coverage radius of the reselected cell within the RAT to which the first cell belongs, or the RAT to which the first cell belongs The average coverage radius of multiple reselected cells within).

Exemplarily, the terminal 101 may determine the first number of cell reselections performed by the terminal 101 in the first time period according to the information of one or more reselected cells. In other words, the first number is the number of cell reselections performed by the terminal 101 in the first time period. The number of cell reselections.

In a possible example, the terminal 101 may scale the first number according to the first scaling factor, and determine the movement state of the terminal 101 according to the scaled number (hereinafter referred to as the second number). For example, the mobile state of the terminal 101 can be determined according to the first duration and the second number of the first time period.

Exemplarily, the first number, the first scaling factor, and the second number may satisfy the following formula:

M=N×k ₁ (Formula 1);

Wherein, M is the second number, N is the first number, k ₁ is the first scaling factor, and k ₁ >0.

Exemplarily, if the average coverage radius of the reselected cell of the terminal 101 in the RAT to which the first cell belongs is smaller than the expected average coverage radius of the reselected cell in the RAT to which the second cell belongs, k ₁ <1.

There may be multiple ways for the terminal 101 to determine the first scaling factor, which will be described below by way of example.

Manner 1: The first scaling factor is broadcast by the first cell.

The terminal 101 may receive system information broadcast by the first cell, and the system information may include one or more scaling factors, and the one or more scaling factors include the first scaling factor. Exemplarily, when the first cell is an NR cell, the system information may be a system information block (system information block, SIB)5. When the first cell is an LTE cell, the system information may be SIB24.

When the number of scaling factors included in the system information broadcast by the first cell is one, the terminal 101 may use the scaling factor as the first scaling factor.

When the system information broadcasted by the first cell includes multiple scaling factors, for example, the system information broadcasted by the first cell includes a scaling factor list, and the list includes multiple scaling factors, the terminal 101 can use each scaling factor The corresponding relationship with the information of the reselected cell and the information of the one or more reselected cells determines the first scaling factor from a plurality of scaling factors. The information of the one or more reselected cells may include the identification ID of the one or more reselected cells; or, the frequency band of the one or more reselected cells; or, the one or more reselected cells The frequency of the cell; or, the subcarrier interval of the one or more reselected cells; or, the cell reselection time of the one or more reselected cells; or, the frequency of the one or more reselected cells Point; or, the coverage radius of the one or more reselected cells. Wherein, the correspondence between each scaling factor and the information of the reselected cell may be broadcast by the first cell.

Exemplarily, the terminal 101 may determine the first scaling factor from multiple scaling factors according to the information of the one or more reselected cells. For example, the terminal 101 may determine the first scaling factor from multiple scaling factors according to the correspondence between each scaling factor and the first coverage radius condition and the first coverage radius of the first cell. For example, the first coverage radius of the first cell may be the coverage radius of the first cell. When the first coverage radius of the first cell satisfies the first coverage radius condition corresponding to a certain scaling factor (for example, the coverage radius of the first cell belongs to the radius range corresponding to the first coverage radius condition), the scaling factor can be determined Is the first zoom factor.

In implementation, the multiple scaling factors broadcast by the first cell may be the same as the average coverage radius of one or more neighboring cells (which may include the second cell) of the first cell or the average coverage of the neighboring cell and the neighboring cells of the neighboring cell The radius corresponds.

Manner 2: The first scaling factor is broadcast by the second cell.

The terminal 101 may receive system information broadcast by the second cell, and the system information may include one or more scaling factors, and the one or more scaling factors include the first scaling factor. Exemplarily, the system information may be SIB1.

When the number of scaling factors included in the system information broadcast by the second cell is one, the terminal 101 may use the scaling factor as the first scaling factor.

When the system information broadcasted by the second cell includes multiple scaling factors, for example, the system information broadcasted by the second cell includes a scaling factor list, and the list includes multiple scaling factors, the terminal 101 can use each scaling factor The corresponding relationship with the information of the reselected cell and the information of the one or more reselected cells determines the first scaling factor from a plurality of scaling factors. The information of the one or more reselected cells may include the identification ID of the one or more reselected cells; or, the frequency band of the one or more reselected cells; or, the one or more reselected cells The frequency of the cell; or, the subcarrier interval of the one or more reselected cells; or, the cell reselection time of the one or more reselected cells; or, the frequency of the one or more reselected cells Point; or, the coverage radius of the one or more reselected cells. Wherein, the correspondence between each scaling factor and the information of the reselected cell may be broadcast by the second cell.

Exemplarily, the terminal 101 may determine the first scaling factor from the multiple scaling factors broadcast by the second cell according to the information of the one or more reselected cells. For example, the terminal 101 may determine the first scaling factor from multiple scaling factors according to the correspondence between each scaling factor and the second coverage radius condition and the second coverage radius of the first cell. Wherein, the second coverage radius of the first cell may be the coverage radius of the first cell. When the second coverage radius of the first cell satisfies the second coverage radius condition corresponding to a certain scaling factor, the scaling factor may be determined as the first scaling factor. It should be understood that the correspondence between each scaling factor and the second coverage radius condition may be the same as or different from the correspondence between each scaling factor and the first coverage radius condition in the system information broadcast by the first cell. , This application is not specifically limited.

In implementation, the multiple scaling factors broadcast by the second cell may correspond to the coverage radius of the second cell or the average coverage radius of the second cell and one or more neighboring cells of the second cell.

Manner 3: Determine the first scaling factor according to the cell size metric value of the first cell and the cell size metric value of the second cell.

Wherein, the terminal 101 may receive the cell size metric value of the first cell broadcast by the first cell through system information, and/or receive the cell size metric value of the second cell broadcast by the second cell through system information.

Exemplarily, the cell size measurement value of the first cell is the cell size measurement value of the first cell itself, or is the average cell size measurement value of the RAT to which the first cell belongs; the cell size measurement value of the second cell It is the cell size measurement value of the second cell itself, or is the average cell size measurement value of the RAT to which the second cell belongs.

Exemplarily, the cell size measurement value in this application refers to a parameter that can be used to measure the cell size, such as the coverage radius of the cell.

Exemplarily, the first scaling factor may be determined according to the following formula:

k ₁ =(r1/r2) (Formula 2);

Where k ₁ is the first scaling factor, r1 is the cell size measurement value of the first cell (such as the coverage radius of the first cell), and r2 is the cell size measurement value of the second cell (such as the second The coverage radius of the cell).

In another example, the following formula may be satisfied among the first number, the first scaling factor, and the second number:

M=(N/k ₁ ) (Formula 3);

In this example, the first scaling factor can be determined according to the following formula:

k ₁ =(r2/r1) (Formula 4);

In addition, in this example, the first scaling factor can also be determined by referring to the method in "Method 1" and/or "Method 2" when determining the first scaling factor in the above example, which will not be repeated here.

Exemplarily, according to the above method, the terminal 101 may use the above second number as the number of cell reselections performed by the terminal 101 within the first time period. When determining the mobile state of the terminal 101, if the time period corresponding to the second number is greater than or equal to T _CRmax, the second number of the cells in the cell reselection time comparing the number of distributed within a time period T _CRmax reselection and _N CR_H cell reselection, cell reselection if the number reaches (or exceeds) _N CR_H , It is determined that the terminal 101 is moving at a high speed; if the number of reselected cells does not reach (or does not exceed) N _{CR_H} , the terminal 101 compares the number of reselected cells with the size of N _{CR_M} , if the number of reselected cells If N _{CR_M} is reached (or exceeded), it is determined that the terminal 101 is in a medium-speed moving state; if the number of reselected cells does not reach (or does not exceed) N _{CR_M} , the terminal 101 continues to determine whether it meets the aforementioned requirements for entering the high-speed moving state or medium The condition of the fast moving state. If neither the conditions for entering the high-speed moving state nor the conditions for entering the medium-speed moving state are satisfied in T _CRmaxHyst , the terminal 101 can determine that its own moving state is a normal moving state. If the duration corresponding to the second number is less than T _CRmax , then the UE will inherit the mobility state determined under the RAT to which the first cell belongs, or fall back to the medium-speed mobility state.

It should be understood that the duration corresponding to the number of cell reselections in this application refers to the time interval between the first cell reselection and the last cell reselection in the number of cell reselections.

In another possible example, the terminal 101 may scale the duration of the first time period (hereinafter referred to as the first duration) according to the second scaling factor, and according to the scaled duration (hereinafter referred to as the second duration) ) And the first number to determine the mobile state of the terminal 101.

Exemplarily, the first duration, the second scaling factor, and the second duration satisfy the following formula:

T'=T×k ₂ (Formula 5);

Wherein, T′ is the second duration, T is the first duration, k ₂ is the second scaling factor, and k ₂ >0.

Exemplarily, if the average coverage radius of the reselected cell of the terminal 101 in the RAT to which the first cell belongs is smaller than the expected average coverage radius of the reselected cell in the RAT to which the second cell belongs, k ₂ >1.

There may be multiple ways for the terminal 101 to determine the second scaling factor, which will be described below by way of examples.

Manner 1: The second scaling factor is broadcast by the first cell.

Wherein, the terminal 101 may receive the cell size measurement value (such as coverage radius) of the first cell broadcast by the first cell, and/or the cell size measurement value (such as coverage radius) of the second cell broadcast by the second cell. Exemplarily, when the first cell is an NR cell, the cell size metric value of the first cell may be carried in SIB5. When the first cell is an LTE cell, the cell size metric value of the first cell may be carried in SIB1. When the second cell is an NR cell, the cell size metric value of the second cell can be carried in SIB5. When the second cell is an LTE cell, the cell size metric value of the second cell may be carried in SIB1.

Exemplarily, the second scaling factor can be determined according to the following formula:

k ₂ =(r2/r1) (Formula 6);

Where k ₂ is the second scaling factor, r1 is the cell size measurement value of the first cell (such as the coverage radius of the first cell), and r2 is the cell size measurement value of the second cell (such as the second The coverage radius of the cell).

When determining the mobile state of the terminal 101, if the second time period is greater than or equal to T _CRmax , the number of the first cell in the cell reselection time comparing the number of re-distributed within the time period T _CRmax cell reselection with _N CR_H selected, if the number of cell reselection reaches (or exceeds) _N CR_H, is determined The terminal 101 is moving at a high speed; if the number of reselected cells does not reach (or does not exceed) N _{CR_H} , the terminal 101 compares the number of reselected cells with the size of N _{CR_M} , and if the number of reselected cells reaches (or If it exceeds) N _{CR_M} , it is determined that the terminal 101 is in a medium-speed moving state; if the number of reselected cells does not reach (or does not exceed) N _{CR_M} , the terminal 101 continues to determine whether it satisfies the aforementioned high-speed or medium-speed moving state If neither the conditions for entering the high-speed movement state nor the conditions for entering the medium-speed movement state are satisfied in T _CRmaxHyst , the terminal 101 can determine that its own movement state is a normal movement state. If the second duration is less than T _CRmax , then the UE will inherit the mobile state determined by the RAT to which the first cell belongs, or fall back to the medium-speed mobile state.

Or, after reselecting from the first cell to the second cell of the different system, the fourth duration is determined according to the fourth scaling factor and the third duration, and the movement state of the terminal 101 is determined according to the fourth duration. By adopting the above method, the terminal 101 realizes a fast and reasonable judgment of the moving state after each cell reselection.

As shown in FIG. 9, the method for determining the mobile state of a terminal provided in an embodiment of the present application may include the following steps:

S601: The terminal 101 reselects from the first cell to the second cell.

S602: The terminal 101 determines a third number according to the third scaling factor, and determines the movement state of the terminal 101 according to the third number, where the third scaling factor is determined according to the coverage radius of the second cell. or,

S603: The terminal 101 determines the fourth duration according to the fourth scaling factor and the third duration, and determines the movement state of the terminal 101 according to the fourth duration. Wherein, the third duration is the duration from the reselection of the terminal 101 to the first cell to the reselection of the terminal 101 to the second cell.

It should be understood that, in the process shown in FIG. 9 above, S602 and S603 are executed alternatively.

In the implementation of S602, the third scaling factor and the third quantity satisfy the following formula:

P = l ₁ (Formula 9);

Wherein, l ₁ is the third scaling factor, and P is the third number.

Exemplarily, the above third scaling factor may be determined according to the following method.

Manner 1: The third scaling factor is broadcast by the second cell.

The terminal 101 may receive system information broadcast by the second cell, and the system information may include the third scaling factor. Exemplarily, when the first cell is an NR cell, the system information may be SIB5. When the first cell is an LTE cell, the system information may be SIB24.

Manner 2: The terminal 101 determines the third scaling factor according to at least one parameter among the reference cell coverage radius, the cell size metric value of the first cell, or the cell size metric value of the second cell.

The above reference cell coverage radius may be broadcast by the first cell and/or the second cell, or the reference cell coverage radius may take a set value, or be pre-configured, or be configured through dedicated signaling before.

The cell size measurement value of the above first cell (such as the coverage radius of the first cell) may be broadcast by the first cell. The cell size measurement value of the second cell (such as the coverage radius of the second cell) may be broadcast by the second cell. Exemplarily, when the first cell is an NR cell, the cell size metric value of the first cell may be carried in SIB5. When the first cell is an LTE cell, the cell size metric value of the first cell may be carried in the SIB24. When the second cell is an NR cell, the cell size metric value of the second cell can be carried in SIB5. When the second cell is an LTE cell, the cell size metric value of the second cell can be carried in the SIB24. Alternatively, the cell size metric value of the first cell and/or the cell size metric value of the second cell are both carried in SIB1.

In a possible example, the third scaling factor can be determined according to the following formula:

l ₁ = (r/R) (formula ten);

Wherein, l ₁ is the third scaling factor, r is the cell size measurement value of the second cell (such as the coverage radius of the second cell), and R is the reference cell coverage radius.

In another possible example, the third scaling factor can be determined according to the following formula:

For example, the base station of the second cell may determine the third scaling factor according to the above formula ten or formula eleven, and broadcast the third scaling factor through system information.

In another example, the following formula may be satisfied between the third scaling factor and the third number:

P=(1/l ₁ ) (Formula 12);

Wherein, l ₁ is the third scaling factor, and P is the third number.

In this example, the third scaling factor can be determined according to the following formula:

l ₁ = (R/r) (Formula 13);

Or, in this example, the third scaling factor can be determined according to the following formula:

l ₁ = (2R)/(r1+r2) (Formula 14);

In addition, in this example, the third scaling factor can also be determined by referring to the method in "Method 1" when determining the third scaling factor in the above example, which will not be repeated here. It should be understood that in this example, the third scaling factor determined by the above method 1 may satisfy the above formula 13 or formula 14. For example, the base station of the second cell may determine the third scaling factor according to the above formula 13 or formula 14, and broadcast the third scaling factor through system information.

Exemplarily, according to the method shown in S206 above, the terminal 101 may use the above third number as the number of cell reselections performed by the terminal 101 in the third time period. When determining the mobile state of the terminal 101, if the cell reselection stored in the terminal 101 is the number of selected (including the third number) when corresponding length greater than or equal to T _CRmax, then the cell reselection time within the length distribution of the comparison the number of _N CR_H reselected cell in the period T _CRmax, if the weight If the number of selected cells reaches (or exceeds) N _{CR_H} , it is determined that the terminal 101 is in a high-speed moving state; if the number of reselected cells does not reach (or does not exceed) N _{CR_H} , the terminal 101 compares the number of reselected cells with N _{CR_H} The size of _{CR_M} . If the number of reselected cells reaches (or exceeds) N _{CR_M} , the terminal 101 is determined to be in a medium-speed mobile state; if the number of reselected cells does not reach (or does not exceed) N _{CR_M} , the terminal 101 continues Determine whether it meets the aforementioned conditions for entering the high-speed or medium-speed moving state. If neither the conditions for entering the high-speed or medium-speed moving state in T _CRmaxHyst are met, the terminal 101 can determine its own moving state It is a normal moving state. If the duration corresponding to the number of cell reselections stored by the terminal 101 (including the third number) is less than T _CRmax , the UE will inherit the mobility state determined by the UE under the RAT to which the first cell belongs, or fall back to the medium-speed mobility state.

In the implementation of S603, the fourth scaling factor, the third duration, and the fourth duration may satisfy the following formula:

t'=t×l ₂ (Equation 15);

Exemplarily, the above fourth scaling factor may be determined according to the following method.

Method 1: The fourth scaling factor is broadcast by the second cell.

The terminal 101 may receive system information broadcast by the second cell, and the system information may include the fourth scaling factor. Exemplarily, when the first cell is an NR cell, the system information may be SIB5. When the first cell is an LTE cell, the system information may be SIB24.

Manner 2: The fourth scaling factor is determined according to at least one parameter of the reference cell coverage radius, the cell size measurement value of the first cell, or the cell size measurement value of the second cell.

The cell size measurement value of the above first cell (such as the coverage radius of the first cell) may be broadcast by the first cell. The cell size measurement value of the second cell (such as the coverage radius of the second cell) may be broadcast by the second cell. Exemplarily, when the first cell is an NR cell, the cell size metric value of the first cell may be carried in SIB5. When the first cell is an LTE cell, the cell size metric value of the first cell may be carried in the SIB24. When the second cell is an NR cell, the cell size metric value of the second cell can be carried in SIB5. When the second cell is an LTE cell, the cell size metric value of the second cell can be carried in the SIB24. Or in all the above cases, the cell size metric values are all carried in SIB1

In a possible example, the fourth scaling factor can be determined according to the following formula:

l ₂ = (R/r) (Formula 16);

Wherein, l ₂ is the fourth scaling factor, r is the cell size measurement value of the second cell (for example, the coverage radius of the second cell), and R is the reference cell coverage radius.

In another possible example, the fourth scaling factor can be determined according to the following formula:

l ₂ =(2R)/(r1+r2) (Formula 17);

Among them, l ₂ is the fourth scaling factor, r1 is the cell size measurement value of the first cell (such as the coverage radius of the first cell), and r2 is the cell size measurement value of the second cell (such as the second Cell coverage radius), R is the reference cell coverage radius.

It should be understood that the fourth scaling factor carried in the system information in the above mode one can satisfy the above formula 16 or formula 17. For example, the base station of the second cell may determine the fourth scaling factor according to the above formula 16 or formula 17, and broadcast the fourth scaling factor through system information.

In another example, the fourth scaling factor, the third duration, and the fourth duration may satisfy the following formula:

t'=(t/l ₂ ) (Formula 18);

In this example, the fourth scaling factor can be determined according to the following formula:

l ₂ = (r/R) (Formula 19);

Or, in this example, the fourth scaling factor can be determined according to the following formula:

l ₂ =(r1+r2)/(2R) (Formula 20);

In addition, in this example, the fourth scaling factor can also be determined by referring to the introduction in "Method 1" when determining the fourth scaling factor in the above example, which will not be repeated here. It should be understood that in this example, the fourth scaling factor determined by the above method 1 may satisfy the above formula 19 or formula 20. For example, the base station of the second cell may determine the fourth scaling factor according to the above formula 19 or formula 20, and broadcast the fourth scaling factor through system information.

If neither the conditions for entering the high-speed moving state nor the conditions for entering the medium-speed moving state are satisfied in T _CRmaxHyst , the terminal 101 can determine itself The movement state of is the normal movement state. If the duration corresponding to the number of cell reselections stored by the terminal 101 is less than T _CRmax , the mobile state determined by the terminal 101 under the RAT to which the first cell belongs is inherited, or the terminal 101 returns to the medium-speed mobile state. Exemplarily, if the RAT to which the second cell belongs is different from the RAT to which the first cell belongs, the terminal 101 may inherit the movement state determined under the RAT to which the first cell belongs, or fall back to the medium-speed movement state; if the RAT to which the second cell belongs If the RAT to which the first cell belongs is the same, the terminal 101 can maintain the current mobile state.
