Technical Field

The present invention relates to the field of wireless communications, and in particular, to a cell reselection based processing method, apparatus, terminal, network device, and storage medium.

Background

In the idle state, the terminal may select a best cell to provide a service signal by monitoring signal quality of the neighboring cell and the current cell, which is referred to as a cell reselection process.

In the related art, the cell reselection scheme is performed based on a frequency priority, and in particular, the terminal high priority resides in a frequency with a higher frequency priority.

Since the high-speed cell and the normal cell may operate in the same frequency band, in this scenario, the cell reselection scheme based on the frequency priority cannot implement cell reselection.

Detailed Description

In the related art, the cell reselection scheme is performed based on the frequency priority, and the terminal may camp on a frequency with higher frequency priority with high priority. Meanwhile, in the same frequency priority, the terminal is sorted based on the R criterion and preferentially resides in the cell with the highest R value.

Wherein, the R criterion is:

R_s＝Q_meas,s+Q_Hyst-Qoffset_temp

R_n＝Q_meas,n-Qoffset-Qoffset_temp。

the specific meaning of each parameter and the ordering of the R-criteria are described in reference to the third generation partnership project (3GPP) protocol TS 36.304.

In the existing Network, some cells are optimized according to Speed, for example, a plurality of cells along a High-Speed rail are cascaded to form a High-Speed rail cell as shown in fig. 1, which may be called a High-Speed Dedicated Network (HSDN). The high-speed rail cell is suitable for the terminal residence of high-speed movement, and the common cell is suitable for the terminal residence of low-speed movement. Since the high-speed cell and the normal cell may operate in the same frequency band, in this scenario, the cell reselection scheme based on the frequency priority cannot implement cell reselection.

Based on this, in various embodiments of the present invention, cell reselection is performed based on the mobility state of the terminal, and a cell matching the mobility state of the terminal is selected for cell reselection.

That is to say, in the scheme of the embodiment of the present invention, the terminal preferentially selects the cell matching with the current moving speed level of the terminal itself, and performs cell reselection, so that the terminal can implement cell reselection in a scenario where the cell is optimized based on speed.

It should be noted that: in this document, a high-speed railway cell may also be referred to as a high-speed railway cell, and may also be referred to as a high-speed railway private network.

An embodiment of the present invention provides a processing method based on cell reselection, as shown in fig. 2, applied to a terminal, where the method includes:

step 201: receiving high-speed reselection information broadcast by network equipment;

here, in an embodiment, the high speed reselection information includes at least one of:

In an embodiment, the high speed reselection information may be carried in a system message, such as a system message block-SIB 1.

The network device may be an access network device, such as a base station or the like.

Here, the terminal starts a function of reselecting a cell matching the terminal moving state at a higher priority when receiving the speed-based cell reselection indication.

That is, the terminal will make a speed priority based cell reselection first, and then make or not make a frequency priority based cell reselection (which may be determined as needed).

More specifically, in response to the speed-based cell reselection indication, determining a current mobility state of the terminal; and preferentially reselecting the cell matched with the current moving state of the terminal.

In one embodiment, the high speed reselection information at least comprises a cell reselection indication based on speed, and is used for activating a function of the terminal to start a higher priority reselection to a cell matched with the terminal movement state;

after receiving the cell reselection indication based on the speed, the terminal starts a function of reselecting a cell matched with the terminal moving state at a higher priority and determines the current moving state of the terminal; and performs cell reselection based on the current mobility state of the terminal.

That is, after receiving the speed-based cell reselection indication, the terminal may learn that cell reselection needs to be performed based on the speed.

In practical application, the high speed reselection information may further include at least one of the following information, so that the terminal performs cell reselection based on speed:

the equivalent cell number, the cell change value threshold and the duration parameter are used for determining the current moving state of the terminal. This information is used for cell reselection.

In practical application, when the terminal receives high-speed reselection information (for example, a speed-based cell reselection indication, a high-speed cell list, or the like), it indicates that there is a high-speed cell around the terminal, and may preferentially select a cell matching with its current moving speed level, to perform cell reselection, that is, may perform cell reselection based on speed priority; when the high speed reselection information is not received, it indicates that there is no high cell around, and cell reselection based on frequency priority can be performed.

In practical application, for the speed-based cell reselection indication, 1-bit information may be used to indicate that the speed-based cell reselection indication is received, for example, when the value is set to 1; when set to 0, this indicates that no speed-based cell reselection indication has been received. Of course, it is also possible to add a speed-based cell reselection indication bit directly to the system message, if the indication bit in the system message indicates that a speed-based cell reselection indication is received, and if the indication bit is not received, the speed-based cell reselection indication is not received.

In an embodiment, for high speed cell indication, 1 bit information may be used for representation. When the terminal receives the 1 bit information, the corresponding cell is a high-speed cell, and when the terminal does not receive the 1 bit information, the corresponding cell is a low-speed cell.

In addition, in practical applications, for the speed-based cell reselection indication and the high-speed cell indication, 1-bit information may be used to indicate that the speed-based cell reselection indication and the high-speed cell indication are jointly indicated, that is, 1-bit information is used to indicate that the network device (such as an eNB, etc. transmits '1', which represents a high-speed cell (a User Equipment (UE) moving at a high speed is higher priority resident in the cell and a UE moving at a low speed is lower priority resident in the cell), and transmits '0' which represents a low-speed cell (a UE moving at a low speed is higher priority resident in the cell and a UE moving at a high speed is lower priority resident in the cell), and if not transmits, represents that the speed-based cell is not activated for reselection, the UE does not initiate cell reselection based on the speed priority and performs reselection based on the frequency priority.

The higher priority reselecting the cell matched with the terminal moving state refers to: when the mobile state of the terminal is high-speed movement, reselecting a high-speed cell at a higher priority; when the mobile state of the terminal is medium-speed movement, reselecting a medium-speed cell at a higher priority; when the moving state of the terminal is normal movement (also can be understood as low-speed movement), the low-speed cell is reselected by higher priority.

In practical application, the terminal can quickly find the high-speed cell by using the same-frequency adjacent high-speed cell list and the different-frequency adjacent high-speed cell list.

Step 202: determining the current moving state of the terminal based on the high-speed reselection information;

specifically, the total reselected cells within the duration corresponding to the duration parameter are counted; wherein, for each reselection cell, if the equivalent cell number is configured, the equivalent cell number is used as the reselection cell count of the corresponding reselection cell;

The equivalent cell number may also be understood as a cell weight, and may be set to M, and when the terminal reselects the cell 1 time, the terminal equivalently reselects M cells, so that the corresponding reselected cell count is M.

The movement state can also be understood as a movement speed level.

In practical application, in order to avoid that a large number of terminals reselect to a common cell during the stop and restart of the terminals on a high-speed rail when the terminals enter a station, the common cell is overloaded. A hysteresis parameter may be set.

Based on this, in an embodiment, when the current moving state of the terminal is determined, when the total number of the cells counted for N consecutive times all exceeds the high speed cell change value threshold, the high speed moving standard is met;

Here, a timer may be provided, and after the moving state of the mobile terminal (which may also be understood as a speed level) is determined once, the timer is started, and after the time-out, the moving state of the mobile terminal is determined again.

In practical application, the value of N can be set as required.

Step 203: and performing cell reselection based on the high-speed reselection information and the current moving state of the terminal.

Here, when the current moving state of the terminal is high-speed movement at the time of cell reselection, the high-speed cell is regarded as a higher priority than other cells except the high-speed cell;

That is, when performing cell reselection, the terminal preferentially selects a cell matching its current moving speed level for cell reselection, which of course includes ignoring frequency priority reselection.

And when the reselection of the cell matched with the current moving state of the terminal fails, reselecting other cells.

When receiving the high-speed cell indication and performing cell reselection, the terminal determines whether the corresponding cell is a high-speed cell or the other cell by using the high-speed cell indication.

When receiving a list of high-speed cells adjacent to the same frequency, and performing cell reselection, the terminal determines a physical layer cell identifier (expressed as physical cell ID, i.e. cell identifier in english) of the high-speed cells adjacent to the same frequency by using the list of high-speed cells adjacent to the same frequency, so as to obtain the high-speed cells adjacent to the same frequency.

When receiving the pilot frequency adjacent high-speed cell list, the terminal determines the physical layer cell identification of the pilot frequency adjacent high-speed cell by using the pilot frequency adjacent high-speed cell list to obtain the pilot frequency adjacent high-speed cell when performing cell reselection.

Correspondingly, the obtained same-frequency adjacent high-speed cells and/or different-frequency adjacent high-speed cells are used as high-speed cells;

Here, in practical application, the terminal may select an intra-frequency adjacent high-speed cell as the high-speed cell, or an inter-frequency adjacent high-speed cell as the high-speed cell, or an intra-frequency adjacent high-speed cell and an inter-frequency adjacent high-speed cell as the high-speed cells according to needs.

The following example illustrates how the terminal performs cell reselection.

In a first scenario, when the terminal determines that the terminal is in a high-speed moving state, the terminal preferentially selects a high-speed cell, and specifically, the terminal sorts cell reselection (for example, based on an R criterion) and starts from a first-ranked cell, and if the cell is a high-speed cell, the terminal camps on the cell. And if the cell is not the high-speed cell, the terminal continuously judges whether the second cell is the high-speed cell or not until finding the cell matched with the speed grade of the terminal.

When the terminal determines that the terminal is in a normal moving state (i.e., a low-speed moving state), it preferentially selects a normal cell (which may also be understood as a low-speed cell), specifically, the terminal sorts the cell reselections (e.g., based on an R criterion), and starts from the first sorted cell, and if the cell is a normal cell, it camps on the first sorted cell. And if the cell is not the common cell, the terminal continuously judges whether the second cell is the common cell or not until finding the cell matched with the speed grade of the terminal.

The terminal may determine that the corresponding cell is a high-speed cell or a normal cell by reading the high-speed cell indication in the system message of the corresponding cell.

In a second scenario, when the terminal determines that the terminal is in a high-speed moving state, the terminal preferentially selects a high-speed cell, and specifically, the terminal performs reselection ranking (for example, ranking based on an R criterion) on cells in a high-speed rail cell list (an intra-frequency adjacent high-speed cell list and/or an inter-frequency adjacent high-speed cell list), and preferentially resides in a first ranked cell.

When the terminal determines that the terminal is in a normal moving state (i.e. a low-speed moving state), a normal cell (which may also be understood as a low-speed cell) is preferentially selected, and when the UE performs cell sorting, the UE preferentially camps on a first-sorted cell which does not belong to a high-speed cell list, that is, the first-sorted cell in cells which do not belong to a high-speed cell list is preferentially selected.

In addition, in practical application, when the terminal determines that the self-moving state changes, for example, the terminal changes from a high-speed moving state to a normal moving state, the terminal preferentially camps on a normal cell.

Correspondingly, an embodiment of the present invention further provides a processing method based on cell reselection, as shown in fig. 3, which is applied to a network device, and the method includes:

step 301: determining high-speed reselection information;

step 302: broadcasting the high speed reselection information.

Here, the high speed reselection information is used for the terminal to determine a current moving state and perform cell reselection.

As previously mentioned, in one embodiment, the high speed reselection information includes at least one of:

In one embodiment, the high speed reselection information includes at least: and based on the speed cell reselection indication, activating a function of the terminal to start the higher priority reselection of the cell matched with the movement state of the terminal.

Further, the high speed reselection information further comprises at least one of the following information:

An embodiment of the present invention further provides a processing method based on cell reselection, and as shown in fig. 4, the method includes:

step 401: the network equipment broadcasts high-speed reselection information;

step 402: the terminal receives high-speed reselection information broadcast by the network equipment;

step 403: determining the current moving state of the terminal based on the high-speed reselection information;

step 404: and performing cell reselection based on the high-speed reselection information and the current moving state of the terminal.

It should be noted that: the specific processing procedures of the terminal and the network device have been described in detail above, and are not described in detail here.

In the method provided by the embodiment of the invention, the network equipment reselects information at a high speed; the terminal receives high-speed reselection information broadcast by the network equipment; determining the current moving state of the terminal based on the high-speed reselection information; and reselecting the cell based on the high-speed reselection information and the current moving state of the terminal, that is, in the scheme of the embodiment of the invention, the terminal preferentially selects the cell matched with the current moving speed grade of the terminal to reselect the cell, so that the terminal can realize cell reselection under the condition that the cell is optimized based on the speed.

In addition, the high-speed cell is determined according to the received same-frequency adjacent high-speed cell list and/or different-frequency adjacent high-speed cell list, so that the high-speed cell can be determined quickly.

The present invention will be described in further detail with reference to the following application examples.

In this embodiment of the application, the UE is in a normal cell and needs to perform cell reselection. And the UE reads the system message, and if the system message does not have the speed-based cell reselection indication, the UE adopts the traditional frequency priority-based cell reselection.

When the UE moves to a new cell, a speed-based cell reselection indication is read from a system message of the cell, or a 'speed-based cell reselection indication' in the message is set to 1, the UE starts speed-based cell reselection (the scheme provided in the embodiment of the present invention).

If the UE detects that the surrounding cells matched with the self rate are not suitable for residing, the UE can select the cell with the best signal quality to reside in the cells which are not matched with the self rate.

And when the moving speed of the UE moving at a high speed is gradually reduced until the UE determines that the UE moves at a low speed, the UE preferentially resides in the low-speed cell when performing cell reselection.

When the UE gradually moves to a cell without broadcasting a 'high-speed rail cell list' or without broadcasting a 'speed-based cell reselection indication', it indicates that there is no surrounding high-speed rail cell, and the UE no longer applies to speed-based cell reselection, and at this time, the UE may use a common frequency priority-based cell reselection scheme.
