Description

Terminal moving state determining method and device

The present application claims priority of chinese patent application with application number 201910157087.6, entitled "method and apparatus for determining terminal moving state" filed in 3/1/2019, which is incorporated herein by reference in its entirety.

Technical Field

The present application relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for determining a mobile state of a terminal.

Background

Cell reselection (cell reselection) is to make a terminal in Radio Resource Control (RRC) IDLE state (IDLE) and inactive state (inactive) camp on a suitable cell under a selected Public Land Mobile Network (PLMN), for example, to select a cell with good communication quality and obtain available services from the cell. When a terminal reselects from a cell employing one Radio Access Technology (RAT) to a cell employing another RAT, for example, the terminal reselects from a fourth generation (4 g) system cell to a fifth generation (5 g) system cell, inter-RAT cell reselection may be initiated.

However, after a terminal reselects a cell of another RAT from a cell of one RAT, the terminal cannot accurately determine a mobility state of the terminal after the terminal reselects in time, and cannot timely select a suitable cell to perform subsequent cell reselection according to the mobility state.

Disclosure of Invention

In a first aspect, the present application provides a mobility state determination method, which may be implemented by a terminal device (or terminal) or a chip in the terminal device. According to the method, a terminal device reselects from a first cell to a second cell, and retains first information, wherein the first cell is a cell of a first RAT, the second cell is a cell of a second RAT, the first information is used for determining a moving state of the terminal device after reselecting to the second cell, and the first information is related to the moving state before reselecting to the second cell or the first information is related to information used for determining the moving state before reselecting to the second cell.

By adopting the design, the terminal device retains the first information after the inter-system cell reselection, the first information can be used for determining the moving state after the terminal device reselects the second cell of the new RAT, and the first information is related to the moving state before the terminal device reselects the second system or the information for determining the moving state, so that the terminal device does not need to re-determine the information for determining the moving state in the second cell any more, and the fast and reasonable judgment of the moving state after the terminal device reselects the cell of the new RAT is realized.

In one possible design, the first RAT and the second RAT may each be one of GSM, UTRAN FDD/TDD, GERAN, CDMA2000, EUTRAN, NR, or future mobile access technology, and the first RAT and the second RAT are different RATs.

In one possible design, if the first information includes information of one or more reselected cells before the terminal device reselects to the second cell, the method may further include: determining the moving state of the terminal device after being reselected to the second cell according to one or more of the following information: information of the one or more reselected cells; or, information of the second cell; or, the first parameter is a parameter related to the moving state of the second cell, or a moving state related parameter of the second cell. The first parameter may be a parameter broadcasted by the second cell. By adopting the design, the terminal device can determine the reselected moving state according to the information of one or more reselected cells before the second cell is reselected, and the information of the second cell and the first parameter are combined, so that the accuracy in determining the moving state is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings. The particular methods of operation in the method embodiments may also be applied to apparatus embodiments or system embodiments.

The following explains the present application with respect to terms:

1. at least one means one, or more than one, i.e., including one, two, three, and more than one.

2. Plural means two, or more than two, that is, two, three and more than two are included.

3. Carrying may mean that a certain message is used to carry certain information or data, or that a certain message is composed of certain information.

4. Determination, in the present application, the term "determining" may include judging, evaluating (evaluate), and the like.

5. The mobile state or terminal mobile state is used for describing the mobile state. When the terminal is in a normal moving state, which indicates that the terminal is in low-speed movement, the time length required by the terminal to perform cell reselection is long. When the terminal is in the medium-speed moving state, it indicates that the terminal is moving at a slightly faster speed, and at this time, the time length required by the terminal to perform cell reselection is shorter than the time length required by the terminal to perform cell reselection in the normal moving state. When the terminal is in a high-speed moving state, which indicates that the terminal is in a fast moving state, the terminal is likely not to obtain a high-quality wireless service from an accessed cell for a long time, and at this time, the time length required by the terminal to perform cell reselection is shorter than the time length required by the terminal to perform cell reselection in a medium-speed moving state, so as to access a cell with better quality.

Hereinafter, embodiments of the present application will be described in detail with reference to the drawings. First, a wireless communication system provided by the embodiment of the present application is introduced, a terminal moving state determining method provided by the present application is applicable to the system, then a terminal moving state determining method provided by the embodiment of the present application is introduced, and finally a terminal and a network device provided by the embodiment of the present application are introduced.

As shown in fig. 1, a wireless communication system 100 provided in the embodiment of the present application includes a terminal 101 and a network device 102.

It should be understood that the wireless communication system 100 provided in the embodiment of the present application is applicable to both a low frequency scene (sub 6G) and a high frequency scene (above 6G).

Illustratively, the terminal 101 may be a terminal (terminal), a Mobile Station (MS), a mobile terminal (mobile station), or a chip, a chip system, or the like, and the terminal 101 is capable of communicating with one or more network devices of one or more communication systems and accepting network services provided by the network devices, which includes but is not limited to the illustrated network device 102. For example, the terminal 101 in the embodiment of the present application may be a mobile phone (or called "cellular" phone), a computer with a mobile terminal, and the like, and the terminal 101 may also be a portable, pocket, hand-held, computer-embedded, or vehicle-mounted mobile device. The terminal 101 may also be a communication chip having a communication module. It should be understood that terminal 101 may be configured to support communication with Network device 102 over a universal user to Network interface (Uu air interface).

The network device 102 may include a Base Station (BS), or includes a Base Station and a radio resource management device for controlling the Base Station, where the Base Station may be a Base Station (BTS) in a GSM or CDMA system, a Base Station (nodeB) in a WCDMA system, an evolved node b (eNB or eNodeB) in an LTE system, a small Base Station (micro/pico eNB) or a Transceiver node (transmission/reception point, TRP) in a Cloud Radio Access Network (CRAN) scenario, or the network device 102 may be a relay Station, an access point, a vehicle-mounted device, a wearable device, a Base Station in a future 5G network, or a Base Station in a future evolved PLMN network, for example, an NR Base Station (gNB), and the embodiment of the present application is not limited.

Network device 102 may form one or more cells to which terminal 101 may camp to access network device 102 when terminal 101 is within the coverage area of the cell formed by network device 102. Currently, the network device 103 may form cells based on different RATs, for example, a cell formed based on 2G/3G RAT, a cell formed based on 4G RAT, and a cell formed based on 5G RAT may be formed based on different RATs. It should be understood that, in the present application, the cell of the first RAT and the cell of the second RAT refer to cells respectively formed based on different RATs. In addition, the cell of one RAT and the cell of another RAT in the present application also refer to cells formed based on different RATs, respectively.

The method for determining the mobile state of the terminal provided by the embodiment of the application can be executed by the terminal 101. The method can be used for the terminal 101 to quickly and reasonably determine the self moving state after reselecting from a cell of one RAT to a cell of another RAT.

The antenna communication system provided by the present application may include a 4G access network, a 5G access network, and a future radio access network (future radio access network cell may be referred to as a future radio access technology cell hereinafter). The 4G access network is, for example, an evolved-terrestrial radio access network (E-UTRAN), and the 5G access network is, for example, a next generation radio access network (NG-RAN).

As shown in fig. 2, the E-UTRAN may consist of one or more enbs providing E-UTRA user plane and control plane protocol termination nodes towards the terminal, e.g., terminal 101. The eNBs are interconnected by an X2 interface. The eNB is also connected to a Mobility Management Entity (MME) through an S1-MME interface, and is connected to a serving gateway (S-GW) through an S1-U interface, so as to implement connection between an access network and a 4G core network.

The cell formed by the gNB may be referred to as an NR cell hereinafter, and the cell formed by the ng-eNB may be referred to as an EUTRA/5GC cell hereinafter.

The EUTRA cell and the NR cell are cells based on different RATs. It can be understood that the method provided in the embodiment of the present application may be applied to the determination of the mobility state after the terminal reselects from the EUTRA cell to the NR cell or the future radio access technology cell. The method can also be used for determining the mobility state of the terminal after the terminal reselects from an NR cell or a future radio access technology cell to an EUTRA cell. In addition, the method can also be applied to the determination of the mobility state after the terminal reselects from an NR cell to a future radio access technology cell, or the determination of the mobility state after the terminal reselects from a future radio access technology cell to an NR cell.

With reference to fig. 4, a terminal 101 shown in fig. 1 is taken as an execution subject to describe the method for determining the mobile state of the terminal according to the embodiment of the present application:

s101: the terminal 101 reselects from a first cell to a second cell, where the first cell is a cell of a first RAT and the second cell is a cell of a second RAT. In an implementation, the first RAT and the second RAT may be one of a 2G/3G RAT, a 4G RAT, a 5G RAT, or a future mobile access technology, respectively, and the first RAT and the second RAT are different RATs. The second cell may be the first cell in the second RAT to which the terminal 101 reselects.

S102: the terminal 101 retains first information for determining a mobility state after the terminal 101 reselects to the second cell, the first information being related to a mobility state before the terminal 101 reselects to the second cell, or the first information being related to information for determining a mobility state before the terminal 101 reselects to the second cell.

By adopting the method, the terminal 101 reserves the first information after reselecting the second cell through the inter-system cell reselection process, and determines the mobile state of the terminal 101 after reselecting the second cell according to the first information, and the mobile state can be determined quickly and reasonably because the terminal 101 does not need to collect the information required for judging the mobile state again.

In the step of S102, the first information is related to the moving state of the terminal 101 before the reselection to the second cell, and means that the first information includes information indicating the moving state of the terminal 101 before the reselection to the second cell, or means that the first information indicates the moving state. Wherein the mobility state before the terminal 101 reselects to the second cell can be represented by the bit value. For example, when two consecutive bits take the value "00", it indicates that the mobility state of the terminal 101 before reselecting to the second cell is a high-speed mobility state; when the two consecutive bits take values of "01", it indicates that the moving state of the terminal 101 before reselecting the second cell is a medium-speed moving state; when the two consecutive bits take the value of "11", it indicates that the mobility state of the terminal 101 before reselecting to the second cell is the normal mobility state. For another example, information stored before the terminal 101 reselects to the second cell to indicate a moving state, such as moving state information stored in a specific location of the terminal 101, may be used as the first information, and the information indicates that the terminal 101 is in a high-speed moving state, a medium-speed moving state, or a normal moving state.

In addition, the first information is related to the information for determining the mobility state of the terminal 101 before the reselection to the second cell, and means that the first information includes the information for determining the mobility state of the terminal 101 before the reselection to the second cell, or means that the first information is used for determining the above-mentioned information for determining the mobility state of the terminal 101 before the reselection to the second cell. The above information for determining the mobility state of the terminal 101 before reselecting to the second cell may include information of one or more reselected cells of the terminal 101 before reselecting to the second cell, and the information of the one or more reselected cells may be used to determine the mobility state 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 times the terminal 101 performs cell reselection within a period of time before reselecting to a second cell, which may be used to determine the mobility state of the terminal 101. The above first information may include information of one or more reselection cells, and may also be used to indicate the information of the one or more reselection cells. In addition, the first information may also include other information that may be used to determine the mobility state of the terminal 101 before reselecting to the second cell, for example, the first information includes the number of times that the terminal 101 performs cell reselection and/or information about reselected cells within a period of time. The related information may also be used to determine the number of times the terminal 101 performs a cell reselection within a period of time before reselecting to the second cell, and thus may be used to determine the mobility state of the terminal 101. The information used for determining the mobility state of the terminal 101 before reselecting the second cell may further include a value of a hysteresis timer corresponding to the first RAT before, during, or after the terminal 101 reselects the second cell.

In one possible implementation, 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 for determining a mobility state before the terminal reselects to the second cell. The reselected cell or cells described herein refer to cells that were reselected before the terminal 101 reselects 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. 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 herein also include the fourth cell.

If the first information includes the information of the one or more reselected cells, after the step shown in S102, the terminal 101 may further determine the mobility state of the terminal 101 after reselecting the second cell according to part or all of the information of the one or more reselected cells, the information of the second cell, or a first parameter, where the first parameter is a parameter related to the mobility state of the second cell (or, the first parameter is a mobility state related parameter).

The information of the one or more reselected cells includes at least one of an Identifier (ID), a frequency band, a frequency, a subcarrier interval, a cell reselection time, or frequency point information of each reselected cell. The cell reselection time of the reselected cell may include a part or all of a time interval between the previous serving cell reselected to the cell by the terminal 101 and the cell reselected to the previous serving cell, a time interval between the cell reselected by the terminal 101 and the next serving cell reselected to the next serving cell, or a time instant when the terminal 101 reselects the cell.

In addition, the information of the second cell includes at least one of an ID, a frequency band, a frequency, a subcarrier interval, a cell reselection time, or frequency point information of the second cell. The cell reselection time corresponding to the second cell may include a time interval between the previous serving cell (i.e., the first cell) reselected to the second cell and the second cell reselected by the terminal 101, a time interval between the second cell reselected by the terminal 101 and the next serving cell reselected to the second cell, or a part or all of the time when the terminal 101 reselects to the second cell.

Illustratively, the terminal 101 may receive a broadcast of the second cell to obtain the first parameters referred to above. The first parameter may include T _CRmax 、N _{CR_H} 、N _{CR_M} Or T _CRmaxHyst And the like. Wherein, T _CRmax And may be used to instruct the terminal 101 to determine the duration of the number of cell reselections. N is a radical of hydrogen _{CR_H} And may be used to instruct the terminal 101 to determine what is needed to enter a high mobility state, T _CRmax Requiring an excess number of cell reselections. N is a radical of _{CR_M} Usable to indicate the T required to determine the state of the incoming medium movement _CRmax The number of cell reselections that need to be reached. T is _CRmaxHyst And may be used to indicate the additional time period required to determine entry into the normal mobility state.

For example, after reselecting to the second cell, the method for determining the mobility state 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, and the first parameter is as follows: terminal 101 determines T in the first parameter _CRmax 、N _{CR_H} 、N _{CR_M} And T _CRmaxHyst And combining the information of one or more reselected cells and the information of the second cell to judge T _CRmax The number of times of cell reselection performed by the terminal 101 within the duration is greater than N of the second cell broadcast _{CR_H} If yes, the terminal 101 determines that the moving state is a high-speed moving state; if the number of times is greater than or equal to N broadcast by the second cell _{CR_M} But less than or equal to N _{CR_H} If the mobile state is determined to be the medium-speed mobile state by the terminal 101; if the number of times is less than N of second cell broadcast _{CR_M} The terminal 101 continues to determine whether the aforementioned condition for entering the high-speed moving state or the medium-speed moving state is satisfied, and if T is satisfied, the terminal continues to determine whether the aforementioned condition for entering the high-speed moving state or the medium-speed moving state is satisfied _CRmaxHyst And if the condition for entering the high-speed moving state and the condition for entering the medium-speed moving state are not met within the time length, the terminal can determine that the moving state of the terminal is the normal moving state.

In another possible implementation manner, the first information related to S102 may be used to indicate a mobility state of the terminal 101 before reselecting to the second cell, and the mobility state of the terminal 101 before reselecting to the second cell after reselecting to the second cell may be determined as the mobility state of the terminal 101 after reselecting to the second cell. Therefore, with the implementation manner, after the terminal 101 reselects from the cell of the first RAT to the cell of the second RAT, the moving state of the terminal 101 in the cell of the first RAT can be used as the moving state after reselecting to the cell of the second RAT, so that the terminal moving state under the cell of the second RAT can be determined quickly and reasonably.

After determining the mobility state after reselecting the second cell, the terminal 101 may further adjust a value of a reselection timer of the terminal 101 according to the mobility state. Specifically, when the terminal 101 is in the high-speed moving state, the terminal 101 will reselect the value (T) of the timer _{reselectionRAT} ) And multiplying by the parameter sf-High, and taking the calculation result as the value of the reselected timer after adjustment. When the terminal 101 is in a Medium-speed moving state, the terminal 101 multiplies the value of the reselection timer by the parameter sf-Medium, and takes the calculation result as the value of the reselected timer after adjustment.

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 the 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 in a Medium-speed moving state, sf-Medium may be added to Qhyst, and the calculation result may be taken 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 broadcasted by the current serving cell in the form of system information. By adopting the design, when the mobile state is a high-speed or medium-speed mobile state, the timing duration of the reselection timer can be shortened, and the hysteresis parameter Qhyst is reduced, so that the frequency of terminal reselection is improved, and the UE can reselect a high-quality cell as soon as possible.

After the terminal 101 reselects to the second cell, the terminal 101 may further determine the parameter T broadcasted by the second cell _CRmaxHyst And the count value of the hysteresis timer corresponding to the first RAT, and the count value of the hysteresis timer corresponding to the second RAT after the terminal 101 reselects the second cell is set. Here, the count value of the hysteresis timer corresponding to the first RAT may be the hysteresis timer corresponding to the first RAT before the terminal 101 reselects the second cellThe count value of the first RAT, the count value of the hysteresis timer corresponding to the first RAT at the time when the terminal 101 reselects to the second cell, 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 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 In time, 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 smaller than T _CRmaxHyst In this case, 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, it is assumed that the terminal 101 moves to a normal state after reselecting an LTE cell (i.e., a cell of a second RAT) from an NR cell (i.e., a cell of a first RAT), and further, it is assumed that T broadcasted by the LTE cell is T _CRmaxHyst For 240 seconds(s), before, during, or after the NR cell reselects to the LTE cell, the count value of the hysteresis timer of the terminal 101 is 230s (i.e., the count value of the hysteresis timer corresponding to the first RAT is 230 s), and 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 corresponding to the second RAT is set to 230s, the terminal 101 applies the cell reselection method corresponding to the normal mobility state after 10 s. However, if the cell reselection is not performed, that is, the count value of the hysteresis timer after the LTE cell is reselected is returned to 0, the terminal 101 still needs to wait 240s to perform the cell reselection. The terminal 101 needs to apply the cell reselection method corresponding to the high speed state (speed scaling factor is 0.25-1) within the 240s (230 s more than inheritance), and the high speed is compared with the constant speed, at most 4 times of cell reselection needs to be performed within the same time (230 s), and considering that the time length (second level) of the 230s compared with the constant speed for the next cell reselection is much longer, therefore, if the terminal 101 reselects the LTE cell from the NR cell, the count value of the hysteresis timer is not inherited, and the power consumption is significantly increased.

In addition, if the LTE cell is assumedT of broadcast _CRmaxHyst The count value of the hysteresis timer is 180s, that is, the maximum value of the hysteresis timer is 180s, and before, during or after the NR cell reselects to the LTE cell, if the count value of the hysteresis timer of the terminal 101 is 230s, the count value of the hysteresis timer after reselecting to the LTE cell may be set to 180s in order to avoid the timer counting error caused by the terminal inheriting the count value of the hysteresis timer.

As shown in fig. 5, the specific flow of the method for determining the mobile state of the terminal provided in the embodiment of the present application is described with the terminal 101 shown in fig. 1 as an execution subject:

s201: the terminal 101 reselects from a first cell to a second cell, where the first cell is a cell of a first RAT and the second cell is a cell of a second RAT. In an implementation, the first RAT and the second RAT may be one of GSM, UTRAN FDD/TDD, GERAN, CDMA2000, EUTRAN, NR, or future mobile access technology, respectively, and the first RAT and the second RAT are different RATs. The second cell may be the first cell in the second RAT to which the terminal 101 reselects.

S202: the terminal 101 retains first information comprising information of one or more reselected cells before the terminal 101 reselects to the second cell, which information of the one or more reselected cells is used to determine a mobility state before the reselection to the second cell.

S203: the terminal 101 determines the moving state of the terminal 101 after reselecting the second cell according to the first information, the information of the second cell, and the moving state related parameter of the second cell broadcasted by the second cell. After the terminal 101 determines the mobility state after reselecting to the second cell, the terminal 101 may perform subsequent cell reselection according to the mobility state.

After the terminal 101 reselects the second cell under the second RAT, if the information of the reselected cell before the second cell is reselected is not reserved, the terminal 101 can only determine the current mobility state according to the information of the current second cell and the mobility state parameter of the second cell, and the determination result is inaccurate. For example, if the terminal 101 is in a high-speed moving state before moving to the second cell, after the terminal 101 reselects to the second cell, since information of a reselected cell before reselecting to the second cell is cleared, the number of times of reselecting performed by the terminal 101 before the reselection cannot be counted, and the terminal 101 is likely to enter a medium-speed moving state or a normal moving state at this time, so that the terminal cannot perform cell reselection according to the high-speed moving state. This may cause the following problems to occur: first, the terminal is prohibited from accessing (bar) when it accesses after receiving a page in a non-camping cell (which may not be in time to reselect because it is moving too fast). Secondly, the terminal has no time to update the registration area when crossing the registration area, resulting in missing paging. Third, for a terminal device in a V2X system, when the terminal requests a high QoS-demanding service through a sidelink (sidelink), it is difficult to establish a connection to request a mode 1 resource. Fourthly, the terminal in an idle state or an inactive state is difficult to read the mode2 resources broadcasted by the current cell, and the original mode2 resources of the cell before reselection are difficult to ensure the QoS requirement.

If the flow shown in fig. 5 is adopted, the terminal 101 still retains the information of the reselected cell before the second cell is reselected, so that the current moving state can be determined by combining the information of the second cell and the moving state parameter of the second cell, thereby avoiding the above problems. For example, in the above example, if information of a reselected cell before reselecting to the second cell is combined, the terminal 101 may determine to enter a high-speed moving state, so as to reselect a high-quality cell more quickly, thereby avoiding the influence on the service quality.

As shown in fig. 6, the specific flow of the method for determining the mobile state of the terminal provided in the embodiment of the present application is described with the terminal 101 shown in fig. 1 as an execution subject:

s301: the terminal 101 reselects from a first cell to a second cell, where the first cell is a cell of a first RAT and the second cell is a cell of a second RAT. In an implementation, the first RAT and the second RAT may be one of a 2G/3G RAT, a 4G RAT, a 5G RAT, or a future mobile access technology, 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 under the second RAT.

S302: the terminal 101 retains first information for indicating a moving state before the terminal 101 reselects to the second cell.

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

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

By adopting the above flow shown in fig. 6, the terminal 101 still maintains the mobile state before reselecting to the second cell after reselecting to the second cell, so that the influence of the mobile state transfer reset on the service quality can be avoided.

As shown in fig. 7, the specific flow of the method for determining the mobile state of the terminal provided in the embodiment of the present application is described with the terminal 101 shown in fig. 1 as an execution subject:

s401: the terminal 101 reselects from a first cell to a second cell, where the first cell is a cell of a first RAT and the second cell is a cell of a second RAT. In an implementation, the first RAT and the second RAT may be one of a 2G/3G RAT, a 4G RAT, a 5G RAT, or a future mobile access technology, 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 under the second RAT.

S402: the terminal 101 broadcasts according to the parameter T of the second cell _CRmaxHyst And a hysteresis timer corresponding to the first RAT, and the hysteresis timer corresponding to the second RAT after the terminal 101 reselects the second cell is set. 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 In time, the terminal 101 may set the count value of the hysteresis timer corresponding to the second RAT to T _CRmaxHyst . Alternatively, the terminal 101 determines that the count value of the hysteresis timer corresponding to the first RAT is smaller than T _CRmaxHyst And setting 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 above flow shown in fig. 7 may be used in combination with the flow shown in fig. 5 or fig. 6. For example, the step shown as S402 may be performed after S202 shown in fig. 5 or S302 shown in fig. 6.

It should be further understood that the above processes shown in fig. 5-7 are only examples of determining the mobility state after the terminal 101 reselects to the second cell, and this application does not exclude that the terminal 101 reselects to a next serving cell of the second cell from the second cell, and/or that the above first information is still retained after more subsequent cell reselection processes, so that the terminal 101 can still determine the mobility state according to the first information after the terminal 101 reselects to a next serving cell from the second cell.

For example, if the first information includes information of one or more reselected cells before the terminal reselects to the second cell, the terminal 101 may still determine the mobility state according to the information of the one or more reselected cells after reselecting from the second cell to the next serving cell. For example, the terminal 101 may determine to reselect to the next mobility state based on at least one of the following information: information of the one or more reselection cells (or information of some or all of the one or more reselection cells), information of a second cell, information of the next serving cell, or a parameter related to a mobility state of the next serving cell. In addition, if the first information is used to indicate the mobility state of the terminal before reselecting to the second cell, the terminal 101 may still inherit the mobility state after reselecting to the next serving cell from the second cell. Alternatively, the terminal 101 may determine the moving state of the terminal 101 in the next serving cell according to at least one of the following information in combination with the determination method of the moving state provided by the present application: the mobility state, information of the second cell, information of the next serving cell, or a parameter related to the mobility state of the next serving cell.

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

In another method for determining a mobile state of a terminal provided in this embodiment of the present application, when reselecting from a first cell to a second cell in a different system, the terminal 101 may retain or inherit first information, where the first information may include information of one or more reselected cells of the terminal under a RAT to which the first cell belongs, and the information of the one or more reselected cells is used to determine a mobile state of the terminal 101 (where the mobile state refers to a mobile state when the terminal apparatus reselects to the second cell or after reselecting to the second cell), so that the terminal 101 may perform a determination of the mobile state according to the information of the one or more reselected cells, so that the terminal 101 realizes a fast and reasonable determination of the mobile state after performing a reselection of the cell in the different system.

As shown in fig. 8, the method for determining a mobile state of a terminal according to the embodiment of the present application may include the following steps:

s501: the terminal 101 reselects from the first cell to the second cell. The first cell is a cell under a first RAT, and the second cell is a cell under a second RAT.

S502: the terminal 101 retains first information including information of one or more reselecting cells that can be used to determine the mobility state of the terminal 101.

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

For example, the terminal 101 may determine a first number of cell reselections performed by the terminal 101 in the first time period according to the information of the 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.

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

Illustratively, the first number, the first scaling factor, and the second number may satisfy the following equations:

M＝N×k ₁ (formula one);

wherein M is the second number, N is the first number, k ₁ Is a first scaling factor, k ₁ ＞0。

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

The manner in which the terminal 101 determines the first scaling factor may be various and is described below by way of example.

Mode one, a first scaling factor is broadcast by a first cell.

The terminal 101 may receive system information broadcasted by the first cell, where the system information may include one or more scaling factors, and the one or more scaling factors include the first scaling factor. For example, when the first cell is an NR cell, the system information may be a System Information Block (SIB) 5. When the first cell is an LTE cell, the system information may be SIB24.

When the system information broadcast by the first cell includes one scaling factor, the terminal 101 may use the scaling factor as the first scaling factor.

When the system information broadcasted by the first cell includes a plurality of scaling factors, for example, the system information broadcasted by the first cell includes a scaling factor list including a plurality of scaling factors, the terminal 101 may determine the first scaling factor from the plurality of scaling factors according to a correspondence relationship between each scaling factor and information of the reselected cell and information of the one or more reselected cells. The information of the one or more reselection cells may include an identification, ID, of the one or more reselection cells; or, the frequency bands of the one or more reselected cells; or, a frequency of the one or more reselected cells; or, a subcarrier spacing of the one or more reselecting cells; or, a cell reselection time of the one or more reselected cells; or, the frequency points of the one or more reselected cells; or a coverage radius of the one or more reselected cells. Wherein a correspondence between each scaling factor and information of reselected cells may be broadcast by the first cell.

For example, the terminal 101 may determine the first scaling factor from a plurality of 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 a plurality of scaling factors according to a 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 a coverage radius of the first cell. When the first coverage radius of the first cell satisfies a first coverage radius condition corresponding to a certain scaling factor (e.g., the coverage radius of the first cell belongs to a radius range corresponding to the first coverage radius condition), the scaling factor may be determined as the first scaling factor.

In an implementation, the plurality of scaling factors broadcasted by the first cell may correspond to an average coverage radius of one or more neighbor cells (which may include the second cell) of the first cell or an average coverage radius of the neighbor cell and neighbor cells of the neighbor cell.

Mode two, the first scaling factor is broadcast by the second cell.

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

When the system information broadcast by the second cell includes one scaling factor, the terminal 101 may use the scaling factor as the first scaling factor.

When the system information broadcasted by the second cell includes a plurality of scaling factors, for example, the system information broadcasted by the second cell includes a scaling factor list including a plurality of scaling factors, the terminal 101 may determine the first scaling factor from the plurality of scaling factors according to the correspondence between each scaling factor and the information of the reselected cell and the information of the one or more reselected cells. The information of the one or more reselection cells may include an identification, ID, of the one or more reselection cells; or, the frequency bands of the one or more reselected cells; or, a frequency of the one or more reselected cells; or, a subcarrier spacing of the one or more reselecting cells; or, a cell reselection time of the one or more reselected cells; or, the frequency points of the one or more reselected cells; or, a coverage radius of the one or more reselected cells. Wherein a correspondence between each scaling factor and information of reselected cells may be broadcast by the second cell.

Illustratively, the terminal 101 may determine the first scaling factor from a plurality of scaling factors broadcast by the second cell based on the information about the one or more reselected cells. For example, the terminal 101 may determine the first scaling factor from a plurality of scaling factors according to a 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 a 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, here, 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 broadcasted by the first cell, and the application is not limited in particular.

In an implementation, the plurality of scaling factors broadcasted by the second cell may correspond to a coverage radius of the second cell or an average coverage radius of the second cell and one or more neighbors of the second cell.

And thirdly, determining a first scaling factor according to the cell size measurement value of the first cell and the cell size measurement value of the second cell.

The terminal 101 may receive a cell size metric of a first cell broadcasted by the first cell through the system information, and/or receive a cell size metric of a second cell broadcasted by the second cell through the system information.

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

For example, the cell size metric refers to a parameter that can be used to measure the cell size, such as the coverage radius of the cell.

Illustratively, the first scaling factor may be determined according to the following equation:

k ₁ = (r 1/r 2) (formula two);

wherein k is ₁ For the first scaling factor, r1 is a cell size metric value of the first cell (e.g., a coverage radius of the first cell), and r2 is a cell size metric value of the second cell (e.g., a coverage radius of the second cell).

In further examples, the following equation may be satisfied between the first number, the first scaling factor, and the second number:

M＝(N/k ₁ ) (formula three);

In this example, the first scaling factor may be determined according to the following equation:

k ₁ = (r 2/r 1) (formula four);

In addition, in this example, the first scaling factor may also be determined by referring to the method in "manner one" and/or "manner two" when the first scaling factor is determined in the above example, which is not described herein again.

For example, according to the above method, the terminal 101 may use the above second number as the number of times that the terminal 101 performs cell reselection within the first time duration, and when determining the moving state of the terminal 101, if the time duration corresponding to the second number is greater than or equal to T _CRmax Distributing the cell reselection times in the second number of reselected cells over a time period T _CRmax Number of reselected cells and N within _{CR_H} Comparing, if the number of reselected cells reaches (or exceeds) N _{CR_H} If yes, determining that the terminal 101 is in a high-speed moving state; if the number of reselected cells does not reach (or exceed) N _{CR_H} The terminal 101 compares the number of reselected cells with N _{CR_M} If the number of reselected cells reaches (or exceeds) N _{CR_M} If yes, determining that the terminal 101 is in a medium-speed moving state; if the number of reselected cells does not reach (or exceed) N _{CR_M} The terminal 101 continues to determine whether it satisfies the aforementioned condition of entering the high-speed moving state or the medium-speed moving state, and if T is satisfied, the terminal continues to determine whether it satisfies the aforementioned condition of entering the high-speed moving state or the medium-speed moving state _CRmaxHyst The terminal 101 may determine that its own moving state is a normal moving state if the conditions for entering the high-speed moving state and the conditions for entering the medium-speed moving state are not satisfied. If the duration corresponding to the second number is less than T _CRmax And inheriting the mobile state determined by the UE under the RAT to which the first cell belongs, or returning to the medium-speed mobile state.

It should be understood that, the duration corresponding to the cell reselection times in this application refers to a time interval between the first cell reselection and the last cell reselection in the cell reselection times.

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 determine the moving state of the terminal 101 according to the scaled duration (hereinafter referred to as the second duration) and the first amount.

Illustratively, the first duration, the second scaling factor, and the second duration satisfy the following equations:

T’＝T×k ₂ (formula five);

wherein T' is the second time length, T is the first time length, k ₂ Is the second scaling factor, k ₂ ＞0。

Illustratively, 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 is ₂ ＞1。

The manner in which the terminal 101 determines the second scaling factor may be various and is described below by way of example.

The first and second scaling factors are broadcast by the first cell.

The terminal 101 may receive system information broadcasted by the first cell, where the system information may include one or more scaling factors, and the one or more scaling factors include a second scaling factor. Illustratively, 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 system information broadcast by the first cell includes one scaling factor, the terminal 101 may use the scaling factor as the second scaling factor.

When the system information broadcasted by the first cell includes a plurality of scaling factors, for example, the system information broadcasted by the first cell includes a scaling factor list including a plurality of scaling factors, the terminal 101 may determine the second scaling factor from the plurality of scaling factors according to the correspondence between each scaling factor and 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, and is not described herein again.

In an implementation, the plurality of scaling factors broadcasted by the first cell may correspond to an average coverage radius of one or more neighboring cells (which may include the second cell) of the first cell or an average coverage radius of the neighboring cell and its neighboring cells.

Mode two, the second scaling factor is broadcast by the second cell.

The terminal 101 may receive system information broadcasted by the second cell, and the system information may include one or more scaling factors, including the second scaling factor. Illustratively, the system information may be SIB1.

When the system information broadcast by the second cell includes one scaling factor, the terminal 101 may use the scaling factor as the second scaling factor.

When the system information broadcasted by the second cell includes a plurality of scaling factors, for example, the system information broadcasted by the second cell includes a scaling factor list including a plurality of scaling factors, the terminal 101 may determine the second scaling factor from the plurality of scaling factors according to the correspondence between each scaling factor and 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 second cell, and is not described herein again.

And thirdly, determining a second 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 a cell size metric value (e.g., coverage radius) of a first cell broadcasted by the first cell and/or a cell size metric value (e.g., coverage radius) of a second cell broadcasted by the second cell. For example, 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 of the first cell may be carried in SIB1. When the second cell is an NR cell, the cell size metric of the second cell may be carried in SIB5. When the second cell is an LTE cell, the cell size metric of the second cell may be carried in SIB1.

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

For example, the second scaling factor may be determined according to the following formula:

k ₂ = (r 2/r 1) (formula six);

wherein k is ₂ For the second scaling factor, r1 is a cell size metric value of the first cell (e.g., a coverage radius of the first cell) and r2 is a cell size metric value of the second cell (e.g., a coverage radius of the second cell).

In further examples, the following equation may be satisfied between the first number, the second scaling factor, and the second number:

T’＝(T/k ₂ ) (formula seven);

In this example, the second scaling factor may be determined according to the following equation:

k ₁ = (r 1/r 2) (formula eight);

In addition, in this example, the second scaling factor may also be determined by referring to the method in "manner one" and/or "manner two" when the second scaling factor is determined in the above example, which is not described herein again.

Illustratively, according to the above method, the terminal 101 may use the above first number as the times of cell reselection by the terminal 101 within the second durationWhen the moving state of the terminal 101 is determined, if the second duration is greater than or equal to T _CRmax Distributing the cell reselection time in the first number of reselected cells to the time period T _CRmax Number of reselected cells and N _{CR_H} Comparing, if the number of reselected cells reaches (or exceeds) N _{CR_H} If yes, determining that the terminal 101 is in a high-speed moving state; if the number of reselected cells does not reach (or exceed) N _{CR_H} The terminal 101 compares the number of reselected cells with N _{CR_M} If the number of reselected cells reaches (or exceeds) N _{CR_M} If yes, determining that the terminal 101 is in a medium-speed moving state; if the number of reselected cells does not reach (or exceed) N _{CR_M} The terminal 101 continues to determine whether it satisfies the aforementioned condition of entering the high-speed moving state or the medium-speed moving state, and if T is satisfied, the terminal continues to determine whether it satisfies the aforementioned condition of entering the high-speed moving state or the medium-speed moving state _CRmaxHyst If the condition for entering the high-speed movement state or the condition for entering the medium-speed movement state is not satisfied, the terminal 101 may determine that its own movement state is the normal movement state. If the second duration is less than T _CRmax And inheriting the mobile state determined by the UE under the RAT to which the first cell belongs, or returning to the medium-speed mobile state.

In another method for determining a mobility state of a terminal provided in this embodiment, when reselecting from a first cell to a second cell of a heterogeneous system, the terminal 101 may determine a third number of reselected cells according to a third scaling factor, and determine a mobility state of the terminal 101 according to the third number (where the mobility state refers to a mobility state of the terminal device when reselecting to the second cell or after reselecting to the second cell). Or after reselecting from the first cell to the second cell of the heterogeneous system, determining a fourth time length according to the fourth scaling factor and the third time length, and determining the moving state of the terminal 101 according to the fourth time length. By adopting the method, the terminal 101 can realize the quick and reasonable judgment of the mobile state after cell reselection every time.

As shown in fig. 9, the method for determining a mobile state of a terminal according to 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 number according to a third scaling factor, which is determined according to the coverage radius of the second cell, and determines the moving state of the terminal 101 according to the third number. Alternatively, the first and second liquid crystal display panels may be,

s603: the terminal 101 determines a fourth time length according to the fourth scaling factor and the third time length, and determines the moving state of the terminal 101 according to the fourth time length. Wherein the third time length is a time length from the terminal 101 reselecting the first cell to the terminal 101 reselecting the second cell.

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

In an implementation of S602, the third scaling factor and the third number satisfy the following formulas:

P＝l ₁ (formula nine);

wherein l ₁ For the third scaling factor, P is the third number.

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

The first and third scaling factors are broadcast by the second cell.

The terminal 101 may receive system information broadcast by the second cell, which may include the third scaling factor. Illustratively, 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.

And in the second mode, the terminal 101 determines a third scaling factor according to at least one parameter of 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 take a set value, or be preconfigured, or previously configured by dedicated signaling.

The above cell size metric value of the first cell (e.g., the coverage radius of the first cell) may be broadcast by the first cell. A cell size metric value of the second cell (e.g., a coverage radius of the second cell) may be broadcast by the second cell. For example, 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 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 SIB24. Or, the cell size metric of the first cell and/or the cell size metric of the second cell are both carried in SIB1.

In one possible example, the third scaling factor may be determined according to the following equation:

l ₁ = (R/R) (formula ten);

wherein l ₁ For the third scaling factor, R is a cell size metric of the second cell (e.g., a coverage radius of the second cell), and R is a reference cell coverage radius.

In another possible example, the third scaling factor may be determined according to the following equation:

l ₁ = (R1 + R2)/(2R) (formula eleven);

wherein l ₁ For the third scaling factor, R1 is a cell size metric value of the first cell (e.g., a coverage radius of the first cell), R2 is a cell size metric value of the second cell (e.g., a coverage radius of the second cell), and R is a reference cell coverage radius.

It should be understood that, in the above manner one, the third scaling factor carried by the system information may satisfy the above formula ten or formula eleven. For example, the base station of the second cell may determine the third scaling factor according to equation ten or equation eleven above and broadcast the third scaling factor through system information.

In further examples, the following equation may be satisfied between the third scaling factor and the third quantity:

P＝(1/l ₁ ) (formula twelve);

wherein l ₁ For the third scaling factor, P is the third number.

In this example, the third scaling factor may be determined according to the following equation:

l ₁ = (R/R) (formula thirteen);

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

l ₁ = (2R)/(R1 + R2) (formula fourteen);

In addition, in this example, the third scaling factor may also be determined by referring to the method in "manner one" in the above example when the third scaling factor is determined, and details are not described here again. It should be appreciated that the third scaling factor, determined in this example by way of one above, may satisfy equation thirteen or equation fourteen above. For example, the base station of the second cell may determine the third scaling factor according to formula thirteen or formula fourteen above and broadcast the third scaling factor through system information.

For example, according to the method shown in S206 above, the terminal 101 may use the above third number as the number of times that the terminal 101 performs cell reselection within the third time duration, and when determining the moving state of the terminal 101, if the time duration corresponding to the number of times (including the third number) of cell reselection stored by the terminal 101 is greater than or equal to T _CRmax Then the cell reselection time within the time length is distributed in the time period T _CRmax Number of reselected cells and N _{CR_H} Comparing, if the number of reselected cells reaches (or exceeds) N _{CR_H} If yes, determining that the terminal 101 is in a high-speed moving state; if the number of reselected cells does not reach (or exceed) N _{CR_H} The terminal 101 compares the number of reselected cells with N _{CR_M} If the number of reselected cells reaches (or exceeds) N _{CR_M} If yes, determining that the terminal 101 is in a medium-speed moving state; if it is heavyThe number of the selected cells does not reach (or exceed) N _{CR_M} Then, the terminal 101 continues to determine whether it satisfies the aforementioned condition for entering the high-speed moving state or the medium-speed moving state, and if T is yes, it continues to determine whether it satisfies the aforementioned condition for entering the high-speed moving state or the medium-speed moving state _CRmaxHyst If the condition for entering the high-speed movement state or the condition for entering the medium-speed movement state is not satisfied, the terminal 101 may determine that its own movement state is the normal movement state. If the time length corresponding to the number of times of cell reselection (including the third number) stored by the terminal 101 is less than T _CRmax And inheriting the mobile state determined by the UE under the RAT to which the first cell belongs, or returning to the medium-speed mobile state.

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

t’＝t×l ₂ (formula fifteen);

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

The first and fourth scaling factors are broadcast by the second cell.

The terminal 101 may receive system information broadcasted by the second cell, and the fourth scaling factor may be included in the system information. Illustratively, 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.

And secondly, determining a fourth scaling factor according to at least one parameter of 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 cell size metric value of the first cell (e.g., the coverage radius of the first cell) may be broadcast by the first cell. A cell size metric value of the second cell (e.g., a coverage radius of the second cell) may be broadcast by the second cell. For example, 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 SIB24. When the second cell is an NR cell, the cell size metric 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 SIB24. Or under the above various conditions, the cell size metric is carried in SIB1

In one possible example, the fourth scaling factor may be determined according to the following equation:

l ₂ = (R/R) (formula sixteen);

wherein l ₂ For the fourth scaling factor, R is a cell size metric of the second cell (e.g., a coverage radius of the second cell), and R is a reference cell coverage radius.

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

l ₂ = (2R)/(R1 + R2) (formula seventeen);

wherein l ₂ For the fourth scaling factor, R1 is a cell size metric value of the first cell (e.g., a coverage radius of the first cell), R2 is a cell size metric value of the second cell (e.g., a coverage radius of the second cell), and R is a reference cell coverage radius.

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

In further examples, the fourth scaling factor, the third duration, and the fourth duration may satisfy the following formulas:

t’＝(t/l ₂ ) (formula eighteen);

In this example, the fourth scaling factor may be determined according to the following equation:

l ₂ = (R/R) (formula nineteen);

Alternatively, the fourth scaling factor may be determined in this example according to the following equation:

l ₂ = (R1 + R2)/(2R) (formula twenty);

In addition, in this example, the fourth scaling factor may also be determined by referring to the description in "manner one" in the above example when the fourth scaling factor is determined, and details are not repeated here. It should be appreciated that the above equations nineteen or twenty may be satisfied by the fourth scaling factor determined in the above manner one in this example. For example, the base station of the second cell may determine the fourth scaling factor according to the above formula nineteen or twenty and broadcast the fourth scaling factor through the system information.

For example, according to the method shown in S603 above, when determining the moving state of the terminal 101, the number of times of cell reselection performed by the terminal 101 in the fourth duration may be determined as 1, and if the duration corresponding to the number of times of cell reselection stored by the terminal 101 (including the number of times of cell reselection performed in the fourth duration) is greater than or equal to T _CRmax Then the cell reselection time within the time length is distributed in the time period T _CRmax Number of reselected cells and N within _{CR_H} Comparing, if the number of reselected cells reaches (or exceeds) N _{CR_H} If yes, determining that the terminal 101 is in a high-speed moving state; if the number of reselected cells does not reach (or exceed) N _{CR_H} The terminal 101 compares the number of reselected cells with N _{CR_M} If the number of reselected cells reaches (or exceeds) N _{CR_M} If yes, determining that the terminal 101 is in a medium-speed moving state;if the number of reselected cells does not reach (or exceed) N _{CR_M} Then, the terminal 101 continues to determine whether it satisfies the aforementioned condition for entering the high-speed moving state or the medium-speed moving state, and if T is yes, it continues to determine whether it satisfies the aforementioned condition for entering the high-speed moving state or the medium-speed moving state _CRmaxHyst If the condition for entering the high-speed movement state or the condition for entering the medium-speed movement state is not satisfied, the terminal 101 may determine that its own movement state is the normal movement state. If the time length corresponding to the cell reselection times stored by the terminal 101 is less than T _CRmax Then, the mobile state determined by the terminal 101 in the RAT to which the first cell belongs is inherited, or the mobile state is returned to the medium-speed mobile state. For example, 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 in the RAT to which the first cell belongs, or fall back to the medium-speed mobility state; if the RAT of the second cell is the same as the RAT of the first cell, the terminal 101 may keep the current moving state.
