S101: The terminal 101 reselects from a first cell to a 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 one of 2G/3G RAT, 4GRAT, 5G RAT or future mobile access technology, and the first RAT and the second RAT are different RATs.

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

In the steps involved in S102, the first information is related to the mobility status of the terminal 101 before reselecting to the second cell, which means that the first information includes information indicating the mobility status of the terminal 101 before reselecting to the second cell, or , which means that the first information is used to indicate the movement state. Wherein, the value of the bit can indicate the mobility 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 a high-speed mobile state; 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 a medium-speed mobile 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 reselects to the second cell, such as the mobile state 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 movement state, or normal movement state.

In addition, the first information is related to the information used to determine the mobile state before the terminal 101 reselects to the second cell, which means that the first information includes information used to determine the mobile state before the terminal 101 reselects to the second cell. The status information, alternatively, refers to the information that the first information is used to determine the aforementioned mobility status of the terminal 101 before reselecting to the second cell.

For example, the information of one or more reselected cells may be used to determine the number of cell reselections performed by the terminal 101 within a period of time before reselecting to the second cell, and the number of times may be used to determine the mobility status of the terminal 101. The above first information may include information of one or more reselected cells, and may also be used to indicate information of 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 the number of times the terminal 101 reselects to the second cell. The information of the community and so on. The relevant information can also be used to determine the number of cell reselections performed by the terminal 101 within a period of time before reselecting to the second cell, and thus can be used to determine the mobility status of the terminal 101 . The information used to determine the mobility status of the terminal 101 before reselecting to the second cell may also include the terminal 101 reselecting to the second cell, when reselecting to the second cell, or reselecting 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 second cell. The previous mobility state of the second cell. The one or more reselected cells mentioned here refer to the cells reselected by the terminal 101 before reselected to the second cell. For example, before S101, the terminal 101 reselects from the third cell to the first cell, then the above one or more reselected cells include the first cell and the third cell involved in S101. As 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 information about one or more reselected cells above, after the step shown in S102, the terminal 101 may also use the above information about one or more reselected cells, information about the second cell, or the first parameter Part or all of the information to determine the mobility state of the terminal 101 after reselecting to the second cell, wherein the first parameter is a parameter related to the mobility state of the second cell (or called, the first parameter is a parameter related to the mobility state).

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

In addition, the above information of the second cell includes at least one item of ID, frequency band, frequency, subcarrier spacing, cell reselection time or frequency point information of the second cell. 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 (that is, the first cell) and the reselecting to the second cell, the time interval between the terminal 101 reselecting The time interval between selecting the second cell and reselecting to the next serving cell of 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, so as to acquire the above-mentioned first parameter. The first parameter may include at least one of T _CRmax , N _{CR_H} , N _{CR_M} or T _CRmaxHyst and other parameters. Wherein, T _CRmax may be used to instruct the terminal 101 to determine the duration of the cell reselection times. N _{CR_H} may be used to instruct the terminal 101 to determine the number of times of cell reselection that needs to be exceeded within the T _CRmax required to enter the high mobility state. N _{CR_M} may be used to indicate the number of times of cell reselection that needs to be reached within T _CRmax required to determine entering the middle mobile state. T _CRmaxHyst can be used to indicate the additional time required to determine the normal mobility state.

For example, after the terminal 101 reselects to the second cell, according to 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 determining the mobile state through the information and the first parameter is as follows: the terminal 101 determines T _CRmax , N _{CR_H} , N _{CR_M} and T _CRmaxHyst in the first parameter, and combines the information of the above one or more reselected cells and the information of the second cell , judging 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 of times broadcast by the second cell N _{CR_M} but less than or equal to N _{CR_H} , then the terminal 101 determines that the mobile state is a medium-speed mobile state; if the number of times is less than the N _{CR_M} broadcast by the second cell, the terminal 101 continues to judge whether the above-mentioned entry into the high-speed mobile state or the medium-speed mobile state is satisfied. If the conditions for entering the high-speed mobility state and the conditions for entering the medium-speed mobility state are not met within the duration of T _CRmaxHyst , the terminal can determine that its own mobility state is a normal mobility state.

In another feasible implementation, the first information involved in S102 can be used to indicate the mobile status of the terminal 101 before reselecting to the second cell, then the terminal 101 can reselect the terminal 101 to the second cell after reselecting to the second cell. The mobility state before reaching the second cell is determined as the mobility state after the terminal 101 reselects to the second cell. Therefore, by adopting this implementation mode, 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 in the cell of the first RAT can be used as the cell after reselecting to the cell of the second RAT. The mobile state of the terminal is realized to quickly and reasonably determine the mobile state of the terminal under the cell of the second RAT.

After determining the mobility 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 mobility state. Specifically, when the terminal 101 is moving at a high speed, 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 in the medium-speed moving state, 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 may also adjust the value of the hysteresis parameter Qhyst according to the moving state. Specifically, when the terminal 101 is in a high-speed moving state, 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, Qhyst can be added to sf-Medium, 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 to increase the frequency of terminal reselection, so that the UE can reselect to high quality as soon as possible district.

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. Here, 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 first time when the terminal 101 reselects to the second cell. 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 to the second cell. It should be understood that the above first information may also include a value of a 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 as T _CRmaxHyst .

In addition, when the terminal 101 judges 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 as the count value of the hysteresis timer corresponding to the first RAT .

For example, it is assumed that the mobile state of the terminal 101 after reselecting from an NR cell (that is, a cell of the first RAT) to an LTE cell (that is, a cell of the second RAT) is a normal mobile state. In addition, it is assumed that the T _CRmaxHyst is 240 seconds (s), before, when or after the reselection from the NR cell to the LTE cell, the count value of the terminal 101 hysteresis timer 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 to the LTE cell, that is, the count value of the hysteresis timer for the second RAT is set to 230s, then after 10s the terminal 101 will use the corresponding Cell reselection method. However, if it is not inherited, that is, the count value of the hysteresis timer returns to 0 after reselecting to an LTE cell, the terminal 101 still needs to wait for 240s before performing cell reselection. The terminal 101 needs to apply the cell reselection method corresponding to the high-speed state (the speed scaling factor is 0.25~1) within the 240s (230s longer than the inheritance), and the high-speed state is compared with the normal speed, and at the same time (230s) at most needs to be 4 times the cell reselection, and considering that 230s is much longer than the normal speed of the next cell reselection (second level), so if the terminal 101 reselects from the NR cell to the LTE cell, the hysteresis timer will not be inherited count value, will significantly increase power consumption.

In addition, if it is assumed that the T _CRmaxHyst broadcast by the LTE cell is 180s, that is, the maximum value counted by the hysteresis timer is 180s, before, when or after reselecting from the NR cell to the LTE cell, if the terminal 101 counts the hysteresis timer If the value is 230s, in order to prevent the terminal from inheriting the count value of the hysteresis timer and causing timer 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 subject to describe 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 a first cell to a 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 can be GSM, UTRAN FDD/TDD, GERAN, CDMA2000, EUTRAN, NR or one of the future mobile access technologies, 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 under 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, and the information of the one or more reselected cells is used to determine the reselection to the second cell The previous mobility status of the second cell is described.

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 mobility status after reselecting to the second cell, the terminal 101 may perform subsequent cell reselection according to the mobility status.

After the terminal 101 reselects to the second cell under the second RAT, if the information of the reselected cell before reselecting to the second cell is not retained, the terminal 101 can only use the information of the current second cell and the information of the second cell The mobile state parameter determines the current mobile state, and its 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, it is impossible to count The number of times of reselection, the terminal 101 is likely to enter the medium-speed mobile state or the normal mobile state at this time, resulting in the terminal being unable to perform cell reselection according to the high-speed mobile state. At this time, the following problems may occur: first, the terminal is prohibited from accessing (bar) when accessing after receiving the paging in the non-resident cell (did not have time to reselect). Second, the terminal does not have time to update the registration area when crossing the registration area, resulting in paging loss. Third, for a terminal device in a V2X system, when the terminal requests a service with high QoS requirements through a sidelink (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 QoS requirements by using the original mode 2 resources of the cell before reselection.

If the process shown in Figure 5 above is used, the terminal 101 still retains the information of the reselected cell before reselecting to the second cell, so that the current mobility status can be determined in combination with the information of the second cell and the mobility status parameters of the second cell, avoiding 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 the high-speed mobile state, so as to reselect to a high-quality cell faster and avoid the occurrence of service quality. influences.

As shown in FIG. 6, the terminal 101 shown in FIG. 1 is still used as the execution subject to describe 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 a first cell to a 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 one of 2G/3G RAT, 4GRAT, 5G RAT or future mobile access technology, 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 under the second RAT.

S302: The terminal 101 retains first information, where the first information is used to indicate the mobility status of the terminal 101 before reselecting to the second cell.

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

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

Using the process shown in FIG. 6 above, after reselecting to the second cell, the terminal 101 still retains the mobility status before reselection to the second cell, so as to avoid the impact of resetting the transfer status on service quality.

As shown in FIG. 7, the terminal 101 shown in FIG. 1 is still used as the execution subject to describe 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 a first cell to a 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 one of 2G/3G RAT, 4GRAT, 5G RAT or future mobile access technology, 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 under the second RAT.

S402: The terminal 101 sets a 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 as T _CRmaxHyst . Or, when the terminal 101 determines that the count value of the hysteresis timer corresponding to the first RAT is less than T _CRmaxHyst , set the count value of the hysteresis timer corresponding to the second RAT as the count value of the hysteresis timer corresponding to the first RAT.

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

In addition, it should be understood that the procedures shown in Figures 5-7 above are only examples of judging the mobility state after the terminal 101 reselects to the second cell, and this application does not rule out the case where the terminal 101 reselects from the second cell to the second cell. One serving cell, and/or after more subsequent cell reselection processes, the above-mentioned first information is still retained, 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 mobile status.

Exemplarily, if the first information includes information about one or more reselected cells before the terminal reselects to the second cell, after reselecting from the second cell to the next serving cell, the terminal 101 can still The information of multiple reselected cells determines the mobility status. For example, the terminal 101 may determine to reselect to the next mobility state according to at least one of the following information: information of the one or more reselected cells (or part or all of the one or more reselected cells information), information about the second cell, information about the next serving cell, or parameters related to the mobility state of the next serving cell. In addition, if the first information is used to indicate the mobile state before the terminal reselects to the second cell, the terminal 101 may 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 Information about the serving cell or parameters related to the mobility state of the next serving cell.

In the above example, for the content of the information of the next serving cell, reference may be made to the description of the information of the second cell in this application. For the content of parameters related to the mobility state of the next serving cell, refer to the description of the first parameter in this application.

In another method for determining the mobile state of the terminal provided in the embodiment of the present application, the terminal 101 may retain or inherit the first information when reselecting from the first cell to a second cell of a different system, and the first information may include all The information of one or more reselected cells under the RAT to which the first cell belongs, the information of the one or more reselected cells is used to determine the mobile state of the terminal 101 (wherein, the mobile state refers to the reselection of the terminal device The mobile state when arriving at the second cell or after reselecting to the second cell), so that the terminal 101 can judge the mobile state according to the information of one or more reselected cells, so that the terminal 101 can realize the Quick and reasonable judgment of mobile status.

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

S501: The terminal 101 reselects from the first cell to the second cell. Wherein, 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, where the first information includes information of one or more reselected cells, and the information of the one or more reselected cells can be used to determine a movement state of the terminal 101.

The information of one or more reselected cells may include some or all of the following information: the ID of the reselected cell, the frequency band of the reselected cell, the frequency of the reselected cell, the subcarrier spacing of the reselected cell, the reselected cell The cell reselection time of the cell, the frequency point 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 itself in the RAT to which the first cell belongs, or the coverage radius of the reselected cell in the RAT to which the first cell belongs. The average coverage radius of multiple reselected cells within the cell).

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

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

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

M=N×k ₁ (Formula 1);

Wherein, M is the second quantity, N is the first quantity, 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, then k ₁ <1.

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

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

The terminal 101 may receive system information broadcast by the first cell, where the system information may include one or more scaling factors, where 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 broadcast by the first cell includes multiple scaling factors, for example, the system information broadcast by the first cell includes a scaling factor list, and the list includes multiple scaling factors, then the terminal 101 can The first scaling factor is determined from the plurality of scaling factors for the corresponding relationship with the information of the reselected cell and the information of the one or more reselected cells. The information of the one or more reselected cells may include the 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 spacing 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 corresponding relationship 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 scaling factor.

In an implementation, the multiple scaling factors broadcast by the first cell may be related to the average coverage radius of one or more neighbors of the first cell (which may include the second cell) or the average coverage of the neighbor and the neighbors of the neighbor corresponding to the radius.

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

The terminal 101 may receive system information broadcast by the second cell, where 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 broadcast by the second cell includes multiple scaling factors, for example, the system information broadcast by the second cell includes a scaling factor list, and the list includes multiple scaling factors, then the terminal 101 may The first scaling factor is determined from the plurality of scaling factors for the corresponding relationship with the information of the reselected cell and the information of the one or more reselected cells. The information of the one or more reselected cells may include the 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 spacing 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 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 a 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 here may be the same as or different from the correspondence between each scaling factor in the above-mentioned system information broadcast by the first cell and the first coverage radius condition , which is not specifically limited in this application.

In an 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.

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

Exemplarily, the cell size metric 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);

Wherein, _k1 is the first scaling factor, r1 is the cell size metric value of the first cell (such as the coverage radius of the first cell), and r2 is the cell size metric value of the second cell (such as the second coverage radius of the cell).

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

M=(N/k ₁ ) (Formula 3);

Wherein, M is the second number, N is the first number, and _k1 is the first scaling factor.

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

k ₁ = (r2/r1) (formula 4);

Wherein, _k1 is the first scaling factor, r1 is the cell size metric value of the first cell (such as the coverage radius of the first cell), and r2 is the cell size metric value of the second cell (such as the second coverage radius of the cell).

In addition, in this example, the first scaling factor may also be determined with reference to the methods in "Mode 1" and/or "Mode 2" when determining the first scaling factor in the above example, and details are not 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 judging the mobile state of the terminal 101, if the time period corresponding to the second number is greater than or equal to T _CRmax , then compare the number of reselected cells whose cell reselection time is distributed within the time period T _CRmax in the second number of reselected cells with N _{CR_H} , if the number of reselected cells reaches (or exceeds) N _{CR_H} , it is determined that the terminal 101 is in a high-speed mobile state; if the number of the reselected cells does not reach (or does not exceed) N _{CR_H} , then the terminal 101 compares the number of the reselected cells with the size of N _{CR_M} , if the number of the reselected cells Reach (or exceed) N _{CR_M} , then determine that the terminal 101 is in the medium-speed mobile state; if the number of reselected cells does not reach (or exceed) N _{CR_M} , then the terminal 101 continues to judge whether it meets the requirements of entering the high-speed mobile state or the medium-speed mobile state. If the conditions for entering the high-speed moving state are not met within T _CRmaxHyst , the terminal 101 may determine that its own moving state is a normal moving state. If the duration corresponding to the second number is less than T _CRmax , inherit the mobile state determined by the UE under the RAT to which the first cell belongs, or fall back to the medium speed mobile state.

It should be understood that the duration corresponding to the number of cell reselections mentioned 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 scale the length of the first time period (hereinafter referred to as the second duration) according to the scaled duration (hereinafter referred to as the second duration). ) and the first quantity determine the movement 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, then k ₂ >1.

There may be multiple manners 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.

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

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 second scaling factor.

When the system information broadcast by the first cell includes multiple scaling factors, for example, the system information broadcast by the first cell includes a scaling factor list, and the list includes multiple scaling factors, then the terminal 101 can The second scaling factor is determined from a plurality of scaling factors based on the corresponding relationship with the information of the reselected cell and the information of the one or more reselected cells. The manner in which the terminal 101 determines the second scaling factor from the multiple scaling factors may refer to the manner in which the terminal 101 determines the first scaling factor from the multiple scaling factors in the system information broadcast by the first cell, which will not be repeated here.

In an implementation, the multiple scaling factors broadcast by the first cell may be related to the average coverage radius of one or more neighbors of the first cell (which may include the second cell) or the average coverage of the neighbor and the neighbors of the neighbor corresponding to the radius.

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

The manner in which the terminal 101 determines the second scaling factor from the multiple scaling factors may refer to the manner in which the terminal 101 determines the first scaling factor from the multiple scaling factors in the system information broadcast by the second cell, which will not be repeated here.

In an 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 second 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 (such as coverage radius) of the first cell broadcast by the first cell, and/or receive the cell size metric 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 may 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 may be determined according to the following formula:

k ₂ =(r2/r1) (Formula 6);

Wherein, k2 is the _second scaling factor, r1 is the cell size metric value of the first cell (such as the coverage radius of the first cell), and r2 is the cell size metric value of the second cell (such as the second coverage radius of the cell).

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

T'=(T/k ₂ ) (Formula 7);

Wherein, T' is the second duration, T is the first duration, and k2 is the _second scaling factor.

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

k ₁ = (r1/r2) (Formula 8);

Wherein, k2 is the _second scaling factor, r1 is the cell size metric value of the first cell (such as the coverage radius of the first cell), and r2 is the cell size metric value of the second cell (such as the second coverage radius of the cell).

In addition, in this example, the second scaling factor may also be determined with reference to the methods in "Mode 1" and/or "Mode 2" when determining the second scaling factor in the above example, and details are not repeated here.

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

Alternatively, after reselecting from the first cell to a second cell of a different system, the fourth duration is determined according to the fourth scaling factor and the third duration, and the mobility status of the terminal 101 is determined according to the fourth duration. By adopting the above method, the terminal 101 can quickly and reasonably judge the moving state after each cell reselection.

As shown in Figure 9, the method for determining the mobile state of the terminal provided in the 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 quantity according to a third scaling factor, and determines a movement state of the terminal 101 according to the third quantity, where the third scaling factor is determined according to a coverage radius of the second cell. or,

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

It should be understood that, in the flow shown in FIG. 9 above, one of S602 and S603 is executed.

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

P=l ₁ (formula nine);

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

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, where 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 of 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 be a set value, or pre-configured, or previously configured through dedicated signaling.

The above cell size metric value of the first cell (such as the coverage radius of the first cell) may be broadcast by the first cell. The cell size metric of the second cell (eg, 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 may 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 the SIB24. Alternatively, both the cell size metric value of the first cell and/or the cell size metric value of the second cell are carried in SIB1.

In a possible example, the third scaling factor may 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 coverage radius of the reference cell.

It should be understood that the third scaling factor carried in the system information in the above manner 1 may satisfy the above formula 10 or formula 11. For example, the base station of the second cell may determine the third scaling factor according to Formula 10 or Formula 11 above, 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 quantity:

P=(1/l ₁ ) (formula twelve);

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

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

l ₁ = (R/r) (formula 13);

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 coverage radius of the reference cell.

Alternatively, in this example, the third scaling factor may be determined according to the following formula:

l ₁ = (2R)/(r1+r2) (Formula 14);

Wherein, _l1 is the third scaling factor, r1 is the cell size metric value of the first cell (such as the coverage radius of the first cell), and r2 is the cell size metric value of the second cell (such as the second The coverage radius of the cell), and R is the coverage radius of the reference cell.

In addition, in this example, the third scaling factor may also be determined with reference to the method in "Mode 1" when determining the third scaling factor in the above example, and details are not repeated here. It should be understood that, in this example, the third scaling factor determined through the first manner above 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 can use the above third number as the number of cell reselections performed by the terminal 101 within the third time period. The time length corresponding to the times of selection (including the third number) is greater than or equal to T _CRmax , then the number of reselected cells whose cell reselection time in the time length is distributed in the time period T _CRmax is compared with N _{CR_H} , if the reselection If the number of selected cells reaches (or exceeds) N _{CR_H} , then it is determined that terminal 101 is in a high-speed mobile state; if the number of reselected cells does not reach (or exceed) N _{CR_H} , then terminal 101 compares the number of reselected cells with N The size of _{CR_M} , if the number of reselected cells reaches (or exceeds) N _{CR_M} , then it is determined that terminal 101 is in a medium-speed mobile state; if the number of reselected cells does not reach (or does not exceed) N _{CR_M} , then terminal 101 continues Determine whether it meets the aforementioned conditions for entering the high-speed mobile state or the medium-speed mobile state, and if T _CRmaxHyst neither meets the conditions for entering the high-speed mobile state nor the conditions for entering the medium-speed mobile state, then the terminal 101 can determine its own mobile state for normal movement. If the duration corresponding to the number of times of cell reselection (including the third number) stored by the terminal 101 is less than T _CRmax , then inherit the mobile state determined by the UE under the RAT to which the first cell belongs, or fall back to the medium speed mobile state.

t'=t×l ₂ (formula fifteen);

Wherein, l ₂ is the fourth scaling factor, t' is the fourth duration, and t is the third duration.

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

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

The terminal 101 may receive system information broadcast by the second cell, where 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: Determine the fourth scaling factor according to at least one parameter among the coverage radius of the reference cell, 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 be a set value, or pre-configured, or previously configured through dedicated signaling.

The above cell size metric value of the first cell (such as the coverage radius of the first cell) may be broadcast by the first cell. The cell size metric of the second cell (eg, 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 may 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 the SIB24. Or in each of the above cases, the cell size measurement value is carried in SIB1

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

l ₂ = (R/r) (formula sixteen);

Wherein, 1 to ₂ is the fourth 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 coverage radius of the reference cell.

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

l ₂ = (2R)/(r1+r2) (Formula 17);

Wherein, _l2 is the fourth scaling factor, r1 is the cell size metric value of the first cell (such as the coverage radius of the first cell), r2 is the cell size metric value of the second cell (such as the second The coverage radius of the cell), and R is the coverage radius of the reference cell.

It should be understood that the fourth scaling factor carried in the system information in the above manner 1 may 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 eighteen);

Wherein, l ₂ is the fourth scaling factor, t' is the fourth duration, and t is the third duration.

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

l ₂ = (r/R) (formula nineteen);

Wherein, 1 to ₂ is the fourth 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 coverage radius of the reference cell.

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

It should be understood that, in this example, the fourth scaling factor determined through the above manner 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.

Exemplarily, according to the method shown in S603 above, when judging the mobile state of the terminal 101, the number of cell reselections performed by the terminal 101 within the fourth time length may be determined as 1, if the number of cell reselections stored by the terminal 101 ( Including the time length corresponding to the number of cell reselections within the fourth time length) is greater than or equal to T _CRmax , then the number of reselected cells whose cell reselection time within the time length is distributed in the time period T _CRmax is compared with N _{CR_H} , If the number of the reselected cells reaches (or exceeds) N _{CR_H} , then determine that the terminal 101 is in a high-speed mobile state; if the number of the reselected cells does not reach (or exceed) N _{CR_H} , then the terminal 101 compares the The size of the number and N _{CR_M} , if the number of the reselected cells reaches (or exceeds) N _{CR_M} , then determine that the terminal 101 is in a medium-speed mobile state; if the number of the reselected cells does not reach (or exceed) N _{CR_M} , then The terminal 101 continues to judge whether it meets the aforementioned conditions for entering the high-speed mobility state or the medium-speed mobility state. If T _CRmaxHyst neither satisfies the conditions for entering the high-speed mobility state nor the conditions for entering the medium-speed mobility state, the terminal 101 can determine that its own 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 , then inherit the mobile state determined by the terminal 101 under the RAT to which the first cell belongs, or fall back 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 mobility state determined under the RAT to which the first cell belongs, or fall back to the medium-speed mobility state; if the RAT to which the second cell belongs If it is the same as the RAT to which the first cell belongs, the terminal 101 can maintain the current moving state.
