Description

Configuration method, terminal and network equipment for cell reselection

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a configuration method, a terminal, and a network device for cell reselection.

Background

Compared with a common cell, an HSDN cell has stronger coverage, so that the times of cell switching and reselection of a UE (for example, a UE on a train) in a continuous High-Speed moving state can be reduced, and better service is provided for a User. Fig. 1 is a view of HSDN cells and normal cells, wherein a dotted circle represents a normal cell, an ellipse represents a HSDN cell, and a station cell is an HSDN cell covering a station.

Due to different coverage areas, HSDN cells broadcast the number of equivalent cells N in order to maintain consistent speed evaluation (MSE) determination_EThat is, the number of HSDN cells equivalent to the number of common cells, the UE will know that the cell is the HSDN cell according to the HSDN cell indication broadcasted by the cell, and if the UE reselects the cell, the UE proceeds to the HSDN cellWhen MSE evaluation is carried out, UE counts the reselected HSDN cell as reselected N_EAnd the common cell can judge the speed of the UE by using a unified MSE standard for the common cell and the HSDN cell.

When idle state UE carries out cell reselection, if the UE is in a high-speed moving state, the reselection priority of the HSDN cell is higher than that of the common cell, the UE in the high-speed moving state can preferentially select the HSDN cell and ignore the frequency priority, and the UE in a non-high-speed moving state can preferentially select the HSDN cell and ignore the frequency priority, so that the UE preferentially selects the common cell and carries out cell reselection according to the frequency priority. However, for a terminal that temporarily interrupts a high-speed moving state (for example, a UE on a train, when the train enters and stops in a scenario, or a UE on a vehicle traveling on an expressway, when the vehicle passes through a service area and stops in a scenario), when the UE is in a non-high-speed moving state, according to the above principle, the UE reselects to a normal cell, which may cause a large amount of UEs to reselect to the normal cell, thereby causing an excessive load to the normal cell, and further consuming more time for the UE to reselect to the HSDN cell after the terminal continues to enter a continuous high-speed moving state.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Some concepts mentioned in the embodiments of the present invention are first explained as follows.

The UE performs MSE according to the parameter broadcasted by the serving cell, and may determine that the UE is in a normal moving state, a high-speed moving state, or a medium-speed moving state.

Within the evaluation time of the serving cell broadcast, if the number of cell reselections within the time exceeds N_MBut does not exceed N_HIf so, judging that the UE is in a medium-speed moving state; if the number of cell reselections exceeds N within the evaluation time broadcast by the serving cell_HIf so, judging that the UE is in a high-speed moving state; and if the cell reselection times do not reach the standard of the high-speed moving state or the standard of the medium-speed moving state within the other evaluation time broadcasted by the service cell, judging that the UE is in the ordinary moving state.

The UE does not compute successive reselections for the same two cells when performing mobility state criteria detection.

The idle state UE can measure the signal quality of the serving cell, when the signal quality of the serving cell meets a certain threshold, the UE can measure the signal quality of an adjacent cell, and when the signal quality of the adjacent cell meets the certain threshold, the UE can perform cell reselection. Different priorities are provided among different frequencies, and the UE can obtain the priority through system information or dedicated signaling. The UE can preferentially evaluate the cells on the high-priority frequency, and if no suitable cell exists on the high-priority frequency point, the cells with the same priority frequency are evaluated. The cell between the same frequencies selects the cell with the strongest signal quality.

In the R15HSDN scenario, in order to provide better service for the UE moving at high speed, the number of cell reselections should be reduced as much as possible. And the idle UE in the high-speed moving state performs cell reselection, the reselection priority of the HSDN cell is higher than that of the common cell, and the reselection priority of the idle UE in the non-high-speed moving state is higher than that of the HSDN cell. However, according to the current principle, when the UE on the train is in a non-high speed state during the time when the train enters and stops, the UE on the train reselects to the normal cell, which causes a high load on the normal cell and consumes more time when the UE reselects to the HSDN cell after the train travels again. How to maintain the UE on the train residing in the HSDN cell is left to be solved when the train is traveling at a low speed and is out of the station when the train is stopped.

The invention provides a configuration method, a terminal and a network device for cell reselection, aiming at the problem that a terminal in a continuous high-speed moving state or a terminal temporarily interrupting the high-speed moving state can be continuously reselected to a high-speed private network, for example, when a train leans to a station, UE in the train can be reselected to a common cell, the behavior can cause a large amount of UE to be reselected to the common cell, so that excessive load is caused to the common cell, and more time can be consumed for the UE in the train to be reselected to an HSDN cell after the train leaves the station.

As shown in fig. 2, a method for configuring cell reselection according to an embodiment of the present invention is applied to a terminal, and includes:

step 21, after the terminal reselects to a first cell, acquiring a pseudo cell reselection configuration parameter for the terminal under the first cell to perform mobility state evaluation;

it should be noted that, in this embodiment of the present invention, the first cell refers to a High Speed Dedicated Network (HSDN) cell, specifically, the first cell includes an HSDN cell covering a station and an HSDN cell not covering the station (the HSDN cell not covering the station may also be considered as a normal HSDN cell), and the pseudo cell reselection configuration parameter includes: at least one of a pseudo cell reselection interval, a maximum pseudo cell reselection frequency, a maximum pseudo cell reselection duration and a pseudo cell reselection indicator. It is further noted that the pseudo cell reselection interval is broadcast by the network device or agreed by a protocol; the maximum pseudo cell reselection times are broadcast by network equipment or agreed by a protocol; the maximum pseudo cell reselection duration is broadcast by network equipment or agreed by a protocol; the pseudo cell reselection indicator is broadcasted or implicitly indicated by the network device (it should be noted that the implicit indication here may be understood that the pseudo cell reselection indicator is implicitly indicated if the normal HSDN cell also performs the cell reselection configuration method according to the embodiment of the present invention, or other parameters in the pseudo cell reselection configuration parameters broadcasted by the first cell are also implicitly indicated by the pseudo cell reselection indicator).

It should be further noted that the pseudo cell reselection interval is determined according to a coverage area of a second cell and a preset speed of the terminal (the preset speed is a specified speed in a specified scene, for example, a specified speed for normal driving of a train, or a specified speed for normal driving of a car on a highway, etc.), where the second cell refers to a cell other than the HSDN cell, i.e., a normal cell. The maximum number of pseudo cell reselections is determined in one of the following ways:

a1, determining according to the time length of the terminal staying in the first cell and/or the reselection interval of the pseudo cell;

a2, determining according to the time length of the terminal passing through the first cell and/or the reselection interval of the pseudo cell;

a3, according to the time length of the terminal residing in the first cell and/or the reselection interval of the pseudo cell.

The maximum pseudo cell reselection time period may also be determined using any one of a1, a2, and A3 described above.

And step 22, configuring the pseudo cell reselection according to the pseudo cell reselection configuration parameters, and acquiring a pseudo cell reselection record.

It should be noted that configuring pseudo cell reselection herein refers to recording pseudo cell reselection, that is, in this case, although the terminal does not perform cell reselection, it still records cell reselection, which is called pseudo cell reselection, and the terminal may perform mobility state evaluation on the terminal according to the pseudo cell reselection record, and further determine a priority for performing cell reselection according to the mobility state of the terminal.

Further, the pseudo cell reselection configuration parameters include: in the pseudo cell reselection interval, the step 22 includes:

It should be noted that, when the pseudo cell reselection configuration parameter includes a pseudo cell reselection interval, the terminal may record, in the first cell, the pseudo cell reselection once at a time specified by the pseudo cell reselection interval according to the pseudo cell reselection interval, and since the pseudo cell reselection interval is fixed, the obtained pseudo cell reselection record is also periodic.

For example, if Cell-0 broadcasts the pseudo Cell reselection interval, the terminal records the pseudo Cell reselection every time the time interval elapses. The validity of the pseudo cell reselection record is consistent with the validity of reselection records of other cells (the other cells refer to the cells except the HSDN cell, namely the common cell) except the first cell, namely the validity of the pseudo cell reselection record is the same as the validity of a normal cell reselection history; or the pseudo cell reselection record is valid within a preset time, in this case, the available time length of the pseudo cell reselection record is agreed, and when the available time length of the pseudo cell reselection record is exceeded, the pseudo cell reselection record is unavailable.

It should be noted that the pseudo cell reselection record is used to: and evaluating the mobile state of the terminal in the first cell and/or evaluating the mobile state of the terminal in at least one cell where the terminal resides behind the first cell. For example, the terminal uses the pseudo Cell reselection record to perform mobility state evaluation in the first Cell, after the terminal reselects to the next HSDN Cell, Cell-1, the pseudo Cell reselection record recorded by the terminal in Cell-0 can be used for mobility state evaluation in Cell-1, so as to continuously ensure that the terminal can reselect to the HSDN Cell, and after the terminal continuously leaves the high-speed mobility state and leaves the coverage of the HSDN Cell, the terminal reselects to the normal Cell.

Further, the pseudo cell reselection configuration parameters include: when the number of pseudo cell reselections is the maximum, the step 12 includes:

Specifically, in this case, after stopping performing the pseudo cell reselection configuration in the first cell, the method for configuring cell reselection further includes one of the following steps:

determining that the terminal is in a common moving state;

It should be noted that, when the terminal obtains the maximum pseudo cell reselection frequency, the terminal records the pseudo cell reselection frequency after performing pseudo cell reselection on the HSDN cell, and when the pseudo cell reselection frequency reaches the maximum pseudo cell reselection frequency, the terminal does not record the pseudo cell reselection frequency any more, and performs speed evaluation according to a normal MSE criterion, or determines that the terminal is in a normal mobile state, and then reselects to the normal cell. It should be further noted that the maximum number of pseudo cell reselections may be determined according to the time that the terminal stays in, passes through, or dwells in the cell, and the pseudo cell reselection interval.

Further, the pseudo cell reselection configuration parameters include: when the maximum pseudo cell reselection time is long, step 12 includes:

determining that the terminal is in a common moving state;

For example, when the terminal acquires the maximum pseudo cell reselection time, the terminal records pseudo cell reselection once at every other agreed pseudo cell reselection interval within the maximum pseudo cell reselection time, and when the pseudo cell reselection configuration time performed in the cell exceeds the maximum pseudo cell reselection time, the terminal does not record the pseudo cell reselection times any more, performs mobile state evaluation according to a normal MSE criterion, or determines that the terminal is in a normal mobile state, and then reselects to a normal cell. It should be further noted that the maximum pseudo cell reselection time may be determined according to the time for the terminal to stay in, pass through, or camp on the cell.

Further, the pseudo cell reselection configuration parameters include: when the pseudo cell reselection indicator is identified, the step 12 includes:

It should be noted that the pseudo cell reselection indicator indicates that the terminal performs pseudo cell reselection, performs pseudo cell reselection for a limited number of times, or performs pseudo cell reselection within a limited time. In this case, after the terminal reselects the first cell, when knowing the pseudo cell reselection indicator of the cell, it is determined that the pseudo cell reselection needs to be configured in the first cell, the terminal needs to configure the pseudo cell reselection according to the specified pseudo cell reselection configuration parameter, and acquire a pseudo cell reselection record, and at least one of the specified pseudo cell reselection configuration parameters (a pseudo cell reselection interval, a maximum number of times of pseudo cell reselection, and a maximum pseudo cell reselection duration) may be acquired from a protocol agreement.

For example, a cell covering a station where a train stops may broadcast a 1-bit indication to notify a terminal that the cell covers the station, and then the terminal may perform reselection recording on the pseudo cell according to at least one of a pseudo cell reselection time interval, a maximum pseudo cell reselection frequency, and a maximum pseudo cell reselection duration, which are agreed by a specified protocol.

It should be noted that the embodiment of the present invention may also be used to perform unified mobility state evaluation on the common HSDN cell, and after the terminal reselects and enters the common HSDN cell to acquire the corresponding system information, the terminal may perform pseudo cell reselection recording according to the agreed pseudo cell reselection time interval, so as to perform mobility state evaluation on the cell or other cells. In combination with a scenario that a terminal in a continuous high-speed moving state may temporarily interrupt the high-speed moving state, for example, a HSDN cell covering a station may have a scenario that the terminal leaves a train, and the HSDN cell covering the station may be different from the configuration of a common HSDN cell.

When the normal HSDN cell also performs a pseudo cell reselection scheme, one of the following cases may be employed:

1. the common HSDN cell and the HSDN cell covering the station can broadcast different maximum pseudo cell reselection times or maximum pseudo cell reselection duration;

2. the common HSDN cell does not broadcast the maximum pseudo cell reselection times or the maximum pseudo cell reselection time length, the common HSDN cell does not limit the pseudo cell reselection times or the maximum pseudo cell reselection time length, and the HSDN cell covering the station broadcasts the maximum pseudo cell reselection times or the maximum pseudo cell reselection time length;

3. the common HSDN cell does not broadcast the maximum pseudo cell reselection times or the maximum pseudo cell reselection time length, the common HSDN cell does not limit the maximum pseudo cell reselection times or the maximum pseudo cell reselection time length, the HSDN cell covering the station broadcasts a pseudo cell reselection indication identifier, and the terminal is indicated to execute the specified maximum pseudo cell reselection times or the maximum pseudo cell reselection time length;

4. the common HSDN cell and the HSDN cell covering the station do not limit the maximum pseudo cell reselection times or the maximum pseudo cell reselection duration;

5. the common HSDN cell and the HSDN cell covering the station use the same maximum pseudo cell reselection times or the maximum pseudo cell reselection duration specified by a protocol;

6. different pseudo cell configuration parameters are specified by a protocol, a common HSDN cell uses default pseudo cell configuration parameters, and an HSDN cell covering a station broadcasts a pseudo cell reselection indication identifier to indicate a terminal to use specific pseudo cell configuration parameters. Wherein the pseudo cell configuration parameter may include at least one of a pseudo cell reselection interval, a maximum number of pseudo cell reselections, and a maximum pseudo cell reselection duration.

Taking train arrival as an example, a specific implementation process of the configuration method for cell reselection according to the embodiment of the present invention is illustrated as follows from different application scenarios.

HSDN cell broadcast pseudo cell reselection indication identifier covering station in application scene one

In this scenario, there are also different scenarios as follows:

the first condition is as follows: the maximum pseudo cell reselection frequency and the maximum pseudo cell reselection time limit do not exist, the protocol specifies the pseudo cell reselection interval T, and the common HSDN cell does not execute the pseudo cell reselection

In this case, the specific implementation flow is as follows:

step A11: cell-0 is a Cell covering a station, and the Cell broadcasts a pseudo Cell reselection indication identifier.

Step A12: the train travels into the cell.

Step A13: and the terminal reselects the cell and reads system information to acquire that the cell is the HSDN cell covering the station.

Step A14: and the terminal records the pseudo cell reselection once every time T according to the appointed pseudo cell reselection interval T.

Step A15: and the UE detects the reselection times within the evaluation time according to the MSE parameter broadcasted by the cell to evaluate the moving state, and the UE uses the pseudo cell reselection record in the cell to evaluate the moving state so as to judge that the UE is in a high-speed moving state.

Step A16: the train drives away from the Cell and enters an adjacent HSDN Cell Cell-1, and the Cell does not broadcast a pseudo Cell reselection indication mark.

Step A17: and the UE reselects to the Cell-1, stops the pseudo Cell reselection record of the Cell-0, detects the reselection times in the evaluation time broadcast in the Cell-1 to evaluate the moving state, and uses the pseudo Cell reselection record history in the Cell-0 to evaluate the speed when the evaluation time covers the time range that the UE resides in the Cell-0, so as to judge that the UE is in the high-speed moving state.

Case two: protocol specifies a maximum pseudo cell reselection number limit N

Step A21: cell-0 is a Cell covering a station, and the Cell broadcasts a pseudo Cell reselection indication identifier.

Step A22: the train travels into the cell.

Step A23: the UE reselects the cell, reads system information to know that the cell is an HSDN cell covering a station, and acquires a maximum pseudo cell reselection frequency limit N specified by a protocol;

specifically, at this step, the ordinary HSDN cell may be implemented in one of the following ways:

in the mode 1, the common HSDN cell does not execute the reselection of a pseudo cell;

in the mode 2, the common HSDN cell executes the pseudo cell reselection, but does not stipulate the maximum pseudo cell reselection frequency;

in the mode 3, the common HSDN cell performs the pseudo cell reselection, the maximum pseudo cell reselection frequency is N1, the maximum HSDN cell reselection frequency of the HSDN cell covering the station is N2, and then N is equal to N2.

Step A24: the UE records the pseudo cell reselection every time T according to the agreed (broadcast by the network device or specified by the protocol) pseudo cell reselection interval T.

Step A25: and the UE detects the reselection times within the evaluation time according to the MSE parameter broadcasted by the cell to evaluate the moving state, and the UE uses the pseudo cell reselection record in the cell to evaluate the moving state so as to judge that the UE is in a high-speed moving state.

Step A261: and (4) the reselection frequency of the pseudo Cell recorded by the UE is less than N, the train drives away from the Cell and enters an adjacent HSDN Cell Cell-1, and the Cell does not broadcast the pseudo Cell reselection indication identifier.

Step A271: and the UE reselects to the Cell-1, stops the pseudo Cell reselection record in the Cell-0, detects the reselection times in the evaluation time broadcast in the Cell-1 to evaluate the moving state, and uses the pseudo Cell reselection record history in the Cell-0 to evaluate the moving state when the evaluation time covers the time range that the UE resides in the Cell-0, so as to judge that the UE is in the high-speed moving state.

Step A262: and the reselection frequency of the pseudo Cell recorded by the UE reaches N, but the UE still resides in the Cell, and the UE stops reselecting the pseudo Cell in the Cell-0 to judge that the UE is in a common moving state.

Step A263: and (3) the pseudo Cell reselection frequency recorded by the UE reaches N, but the UE still resides in the Cell, the UE stops reselecting the pseudo Cell in the Cell-0, and the UE is subjected to the movement state evaluation according to a normal MSE judgment criterion.

And thirdly, the protocol specifies a pseudo cell reselection interval T and a maximum pseudo cell reselection duration T_L

Step A31: cell-0 is a Cell covering a station, and the Cell broadcasts a pseudo Cell reselection indication identifier.

Step A32: the train travels into the cell.

Step A33: UE reselects the cell, reads system information to know that the cell is an HSDN cell covering a station, and obtains the maximum pseudo cell reselection time T specified by a protocol_LUE starts timer t_lDuration is set to T_L；

in the mode 2, the common HSDN cell executes the pseudo cell reselection, but does not stipulate the maximum pseudo cell reselection time length;

in the mode 3, the common HSDN cell performs the pseudo cell reselection, the maximum pseudo cell reselection time length is T1, the maximum pseudo cell reselection time length of the HSDN cell covering the station is T2, and at this time, T is_LEqual to T2.

Step A34: the UE records the pseudo cell reselection every time T according to the agreed (network broadcast or protocol specified) pseudo cell reselection interval T.

Step A35: and the UE detects the reselection times within the evaluation time according to the MSE parameter broadcasted by the cell to evaluate the moving state, and the UE uses the pseudo cell reselection record in the cell to evaluate the moving state so as to judge that the UE is in a high-speed moving state.

Step A361: timer t₁In the running time, the train drives away from the Cell and enters the neighboring HSDN Cell Cell-1, and the Cell does not broadcast the pseudo Cell reselection indication mark.

Step A371: the UE reselects to Cell-1, stops the pseudo Cell reselection record in Cell-0, stops the timer t1, detects the reselection times in the evaluation time broadcast in Cell-1 to evaluate the moving state, and uses the pseudo Cell reselection record history in Cell-0 to evaluate the moving state when the evaluation time covers the time range that the UE resides in Cell-0, and judges that the UE is in a high-speed moving state.

Step A362: timer t₁And if the time is out, the UE still resides in the Cell, and the UE stops reselecting the pseudo Cell in the Cell-0 to judge that the UE is in the ordinary moving state.

Step A363: timer t₁And if the time is out, the UE still resides in the Cell, the UE stops reselecting the Cell-0 pseudo Cell, and the UE is subjected to the mobility state evaluation according to a normal MSE judgment criterion.

The method comprises the following steps that in an application scenario II, pseudo cell reselection intervals are broadcasted by HSDN cells covering stations, and the common HSDN cells do not execute pseudo cell reselection

In this scenario, there are also different scenarios as follows:

case one, no maximum pseudo cell reselection times and maximum pseudo cell reselection duration limit
