Optionally, the network device may obtain historical network slice information of the terminal device through at least three possible implementation manners as follows.

In a possible implementation manner, the network device may receive the first message from the terminal device, so that after receiving the first message, the network device may obtain the terminal device’s information according to the historical network slice information of the terminal device included in the first message. Historical network slice information.

For example, the first message may be an air interface message, which may be an existing radio resource control (Radio Resource Control, RRC) message, such as a UE information request (UE information request) message, or may also be a newly defined air interface Message, the embodiment of this application is not limited here. Exemplarily, each time a terminal device accesses a serving cell, the terminal device may record the network slice information in the corresponding serving cell, the network slice information in the registration area to which the corresponding serving cell belongs, or the tracking area to which the corresponding serving cell belongs. At least one kind of network slice information in the network slice information in the network is recorded as historical network slice information, and the recorded historical network slice information is carried in a first message at a certain time and sent to the network device, so that the network device can obtain Historical network slice information of the terminal device.

In another possible implementation manner, the network device may receive the second message from the second network device; so that after receiving the second message, the network device may obtain the historical network slice information of the terminal device included in the second message Historical network slice information of the terminal device. Wherein, the second network device is a network device used to record historical network slice information of the terminal device, and the network device controls cell handover processing or solves cell ping-pong handover according to the network slice information of its current cell and the recorded historical network slice information Or send the acquired historical network slice information of the terminal device to the first network device, so that the first network device can also perform corresponding processing based on the historical network slice information of the terminal device.

For example, the second message may be a context acquisition message, a handover request message, or a newly defined X2/Xn interface message, which is not limited in this embodiment of the present application. For the second network device, each time a terminal device accesses a serving cell, the network device will record the network slice information in the corresponding serving cell, the network slice information in the registration area to which the corresponding serving cell belongs, or the corresponding serving cell At least one piece of network slice information in the network slice information in the tracking area to which it belongs is recorded as historical network slice information, and the historical network slice information is carried in a second message and sent to the network device, so that the network device can obtain the terminal Historical network slice information of the device.

As an example, take the second network device to record the historical network slice information of the terminal device and send the historical network slice information to the network device as an example, that is, the network device obtains the historical network slice information of the terminal device from the second network device. Of course, also The historical network slice information of the terminal device can be recorded by the terminal device or the core network device. Here, the embodiment of the present application only uses the second network device to record the historical network slice information of the terminal device and send the historical network slice information to the network device as Examples are described, but it does not mean that the embodiments of the present application are limited thereto.

Among them, the activated network slice information is the S-NSSAI corresponding to all protocol data unit sessions (protocol data unit session, PDU session). The S-NSSAI corresponding to all PDU sessions can form an S-NSSAI list. The S-NSSAI The list can also be called NSSAI. The core network device sends the network slice information after establishing a session with the second network device through the PDU session resource establishment (setup) / modification (modification) / release (release) message For the second network device, the second network device records the network slice information as the activated network slice information in the historical network slice information of the terminal device, so that the network device can obtain the historical network slice of the terminal device from the second network device information. It should be noted that when the second network device records the activated network slice information in the historical network slice information of the terminal device, it may also record the serving cell information corresponding to the activated network slice information in the historical network slice information of the terminal device. Optionally, the registration area information corresponding to the activated network slice information can also be recorded in the historical network slice information of the terminal device. Of course, the tracking area information corresponding to the activated network slice information can also be recorded in the terminal. In the historical network slice information of the device.

The allowed network slice information may be sent by the core network device to the second network device when the terminal device initially accesses the network. For example, the core network device may send network slice information to the second network device through an initial context setup message, and the second network device records the network slice information as allowed network slice information in the historical network slice information of the terminal device In this way, the network device can obtain the historical network slice information of the terminal device from the second network device. It should be noted that when the second network device records the allowed network slice information in the historical network slice information of the terminal device, it may also record the serving cell information corresponding to the allowed network slice information in the historical network slice information of the terminal device. Optionally, the registration area information corresponding to the allowed network slice information can also be recorded in the historical network slice information of the terminal device. Of course, the tracking area information corresponding to the allowed network slice information can also be recorded in the terminal. In the historical network slice information of the device.

The network slice information of interest may be sent by the terminal device to the core network device through the second network device when the terminal device initiates a registration request to the network. For example, the terminal device may send the network slice information to the second network device through a registration request message, and the second network device records the network slice information as the network slice information of interest in the historical network slice information of the terminal device and sends it to Core network equipment. For example, the terminal device may send a slice list (S-NSSAI-List) to the second network device through a radio resource control setup complete (RRC setup complete) message, so that the second network device records the slice list after receiving the slice list The slice list is forwarded to the core network device. The slice list is the network slice information requested by the terminal device, and the slice information requested by the terminal device can be understood as the network slice information that the terminal device is interested in. That is, the second network device will record the network slice information of interest, and record the network slice information of interest in the historical network slice information of the terminal device, so that the network device can obtain the history of the terminal device from the second network device Network slicing information. It should be noted that when the second network device records the network slice information of interest in the historical network slice information of the terminal device, it can also record the serving cell information corresponding to the network slice information of interest to the historical network of the terminal device. In the slice information, optionally, the registration area information corresponding to the network slice information of interest can also be recorded in the historical network slice information of the terminal device. Of course, the tracking area information corresponding to the network slice information of interest can also be recorded. Recorded in the historical network slice information of the terminal device. In addition, it should be noted that the slice list (S-NSSAI-List or NSSAI-List) can be pre-configured to the terminal device, or it can be the slice information that the terminal device is actually interested in, or it can be The slice information that the last registered domain allows to support, of course, can also be other slice information, and the embodiment of the present application does not make specific restrictions here.

In another possible implementation manner, the network device may receive the third message from the core network device; so that after receiving the third message, the network device may obtain the terminal device according to the third message including the historical network slice information of the terminal device Historical network slice information.

For example, the third message may be an interface message, and the interface message may be an existing NG interface message, or an existing S1 interface message, or a newly defined interface message, which is not limited in this application. For core network equipment, every time a terminal device accesses a serving cell, the core network device will record the network slice information in the corresponding serving cell, the network slice information in the registration area to which the corresponding serving cell belongs, or the corresponding serving cell At least one type of network slice information in the network slice information in the tracking area to which it belongs is recorded as historical network slice information, and the historical network slice information is carried in a third message and sent to the network device, so that the network device can obtain the terminal Historical network slice information of the device.

It should be noted that when acquiring network history slice information in S301, the above three possible implementations can also be combined, that is, any two of the first message, the second message, or the third message can be used, or the network can be acquired by the three together. Historical slice information, this embodiment of the present application only uses the above three possible implementations as examples. Of course, it is also possible to obtain historical network slice information of a terminal device from other devices or devices or modules (such as centralized node devices). Here, the embodiment of the present application does not specifically limit how the network device obtains the historical network slice information of the terminal device.

After obtaining the historical network slice information of the terminal device, S302 may be executed:

S302. The network device controls the terminal device to access the target cell according to the historical network slice information.

For example, the target cell may be a cell to which the historical network slice information belongs, that is, a cell that the terminal device has previously accessed. Of course, it may also be a new cell, that is, a cell that the terminal device has not accessed before.

The process of determining the target cell can be performed by the network device or by the terminal device, which can be specifically determined according to the current state of the terminal device. For example, when the terminal device is currently in the connected state, the target cell may be one of the one or more candidate cells determined by the network device according to the identifier of the historical network slice; when the terminal device is currently in the idle state or deactivated state, The terminal device may determine the target cell among multiple candidate cells according to the identifier of the historical network slice, and then access the target cell.

It can be seen that, in the information processing method provided by the embodiments of this application, after the network device obtains the historical network slice information of the terminal device, it can control the terminal device to access the target cell based on the historical network slice information, thereby reducing the connection of the terminal device. The risk of entry failure and increase the success rate of entry. It is understandable that, in addition to historical network slice information, other information, such as the signal strength of the cell, can also be considered when determining the target cell, which is not limited in the embodiment of the present application.

It should be noted that in S302, when the network device controls the terminal device to access the target cell based on historical network slice information, if the current state of the terminal device is different, correspondingly, the network device controls the terminal device to access the target cell. The way of the district is different. Optionally, the current state of the terminal device may be a connected state, an idle state, or a deactivated state. In the following, for these three different states, how the network device controls the terminal device to access the target cell according to the historical network slice information under the three different states will be described in detail.

When the terminal device is in the connected state, as an example, please refer to FIG. 4. FIG. 4 is a schematic flowchart of another information processing method provided by an embodiment of this application. The information processing method may include:

S401: The network device obtains historical network slice information of the terminal device.

The historical network slice information includes the identifier of the historical network slice. Optionally, the historical network slice information may be recorded by the terminal device in its own mobility history information (UE mobility history information), or it may also be recorded by the network device in its own mobility history information (UE mobility history information) .

Optionally, the type of historical network slice information includes at least one of the following: activated network slice information, allowed network slice information, or interested network slice information. For details, please refer to the relevant description in S301. The application embodiment will not be repeated.

It should be noted that when the terminal device is in the connected state, the network device can obtain the historical network slice information of the terminal device through the first message, the second message or the third message. Of course, the historical network of the terminal device can also be obtained in other ways. For the specific acquisition method of the slice information, please refer to the relevant description in the above S301. Here, the embodiment of the present application does not make specific limitations.

After obtaining the historical network slice information of the terminal device, the network device may perform the following S402:

S402. The network device determines a target cell according to historical network slice information.

Wherein, the historical network slice information includes the identifier of the historical network slice.

In a possible manner, the network device may determine the target cell in at least one candidate cell. Optionally, the target cell may be determined according to a preset condition, for example, a cell that meets the preset condition is determined as the target cell. The preset condition can be understood as: the slice type in the historical network slice information of the cell includes the current slice type of the terminal device as much as possible, and the current signal strength of the cell is greater than the first threshold. The current slice type of the terminal device refers to the slice type of the terminal device under the aforementioned network device. For example, if the slice types in the historical network slice information of a certain candidate cell are S-NSSAI1 and S-NSSAI2, and the current slice types of the terminal device are S-NSSAI1 and S-NSSAI2, it can be seen that the history of the candidate cell The slice type in the network slice information includes the current slice type of the terminal device, and the signal strength of the candidate cell is greater than the first threshold. In this case, the candidate cell can be determined as the target cell.

It should be noted that if more than one candidate cell meets the preset condition, the target cell may be further combined with other factors to determine the target cell, or a cell may be randomly or arbitrarily selected as the target cell among the cells that meet the preset condition. Exemplarily, in a case where more than one candidate cell meets the preset condition, the target cell may be determined among the multiple candidate cells according to the priority of the slice type in the historical network information of the cell that meets the preset condition. For example, a candidate cell corresponding to a slice type with a higher priority may be determined as the target cell, or a cell may also be randomly selected from multiple cells and determined as the target cell.

When determining the target cell meeting the preset condition according to the historical network slice information, the target cell meeting the preset condition may be determined according to the slice type in the historical network slice information. For example, please refer to FIG. 5. FIG. 5 is a schematic diagram of determining a target cell according to an embodiment of the application. In combination with FIG. 5, it can be seen that the signal strengths of neighboring cells measured by the terminal device are: the first cell The RSRP (Reference Signal Receiving Power) is -110dbm, the first cell is the cell under network device 1, the RSRP of the second cell is -90dbm, the RSRP of the third cell is -100dbm, and the second The cell and the third cell are the cells under the network device 2, and the second cell slice types in the historical network slice information are S-NSSAI1 and S-NSSAI2, and the slice types supported by the third cell are S-NSSAI1, S-NSSAI2, and S -NSSAI3, the current slice types of the terminal device are S-NSSAI1, S-NSSAI2, and S-NSSAI3. Since the slice type supported by the third cell, the terminal device currently has the largest number of slice types, and the RSRP of the third cell is greater than the first threshold Therefore, although the signal strength of the third cell is not optimal, it can be determined as the target cell to try to satisfy the current service corresponding to the network slice information of the terminal device.

Further, the network device may send the configuration information of the target cell to the terminal device to control the terminal device to switch to the target cell according to the configuration information of the target cell (S403-S404). It is understandable that in a possible manner, the network device may obtain the configuration information of the target cell through the handover preparation process.

S403: The network device sends the configuration information of the target cell to the terminal device.

S404: The terminal device switches to the target cell according to the configuration information of the target cell.

It can be seen that when determining the target cell, the network device considers the historical network slice information of the terminal device, and determines the target cell based on the historical network slice information of the terminal device and the current slice information of the terminal device, and determines the target through the network device Cells, and control terminal equipment to access the target cell through configuration information, thereby reducing the risk of access failure and increasing the success rate of access.

For example, please refer to FIG. 6. FIG. 6 is a schematic flowchart of another information processing method provided by an embodiment of this application. The information processing method may include:

S601. The network device obtains historical network slice information of the terminal device.

Optionally, corresponding to a terminal device in an idle state, the type of historical network slice information includes at least one of the following: allowed network slice information or interesting network slice information. When acquiring historical network slice information, the network device can acquire the historical network slice information of the terminal device through the first message. Of course, it can also acquire the historical network slice information of the terminal device in other ways. For the specific acquisition method, please refer to the relevant information in S301 above. Description, here, the embodiments of the present application do not make specific limitations. It is understandable that the network device can receive the historical network slice information of the terminal device through the first message after the terminal device in the idle state is converted to the connected state.

Optionally, when the terminal device in the idle state and the terminal device in the deactivated state record historical network slice information, the historical network slice information of the terminal device can also be recorded in a way of minimizing drive test (MDT) logs The embodiments of this application are not limited here.

Corresponding to the terminal device in the deactivated state, the type of historical network slice information includes at least one of the following: activated network slice information, allowed network slice information, or interesting network slice information. When obtaining historical network slice information, the network device can obtain the historical network slice information of the terminal device through the first message, the second message, or the third message. Of course, the historical network slice information of the terminal device can also be obtained in other ways. For the manner, refer to the related description in S301, and the embodiment of the present application does not make specific limitations here. It is understandable that the network device can receive the historical network slice information of the terminal device through the first message after the terminal device in the deactivated state is converted to the connected state.

For example, if the current serving cell of the terminal device belongs to the second network device, the second network device will record the network slice information of the terminal device and record it in the historical network slice information. Optionally, the terminal device will also record the terminal The network slice information of the device is also recorded in the historical network slice information. Subsequently, the terminal device enters the deactivated state under the second network device, the terminal device moves to the network device, and initiates a radio resource connection recovery (RRC resume) process to the cell under the network device, and connects to the serving cell under the second network device At this time, the network device may initiate a terminal context acquisition (retrieve UE context) process to the second network device, and the second network device may send the historical network slice information of the terminal device to the network device through the context acquisition message; optional The historical network slice information of the terminal device can also be sent to the network device through the RRC resume process.

After obtaining the historical network slice information of the terminal device, the network device may perform the following S602:

S602. The network device determines first parameters corresponding to one or more cells according to the slice information supported by the cell in the historical network slice information.

The first parameter may be a reselection parameter corresponding to each cell, so that the terminal device can obtain the reselection parameter corresponding to each cell according to the first parameter; the first parameter may also be an adjustment value of the reselection parameter of each cell, The terminal device can obtain the reselection parameter corresponding to each cell after adjustment according to the reselection parameter of each cell and the adjusted value of the reselection parameter of each cell.

That is to say, by determining the first parameter corresponding to each cell, the network device is equivalent to determining the reselection parameter corresponding to each cell.

For example, the reselection parameter may include the offset parameter of the cell (for example, Qoffset). Of course, it may also include other parameters, which can be specifically set according to actual needs. Here, the embodiment of the present application does not specifically limit it. When determining the reselection parameters corresponding to one or more cells according to the slice information supported by the cell in the historical network slice information, if the slice type in the network slice information supported by a certain cell includes the slice type required by the terminal device, it can be determined Configure the cell's corresponding reselection parameters to be relatively low so that the cell can be reselected more easily; and/or if the slice type in the network slice information supported by a certain cell does not include the slice type required by the terminal device, It can be determined that the reselection parameter corresponding to the cell is configured to be relatively high, so that the cell is not easily reselected, thereby improving the selection efficiency of the target cell. Among them, the slice type required by the terminal device can be understood as the slice type corresponding to the service supported by the terminal device. In other words, it can be determined that the operation of configuring the reselection parameter of a certain cell to be higher and the operation of configuring the reselection parameter of a certain cell to be lower can be realized at the same time, or alternatively. In a possible manner, the configuration manner of the reselection parameters of a certain cell may be based on the adjustment of the previous reselection parameters. It is understandable that the embodiments of this application do not limit the adjustment direction of the reselection parameters. Different parameters may have different adjustment directions. As long as suitable cells are easier to be reselected, inappropriate cells are not easily selected. Go there.

For example, if the slice types in the historical network slice information of the first cell are NSSAI1, NSSAI2, and NSSAI3, the slice types in the historical network slice information of the second cell are NSSAI2, NSSAI3, NSSAI4, and NSSAI5, and the current slice of the terminal device For network slices of NSSAI2, NSSAI3, and NSSAI5, it can be seen that the slice type in the historical network slice information of the second cell includes the slice type required by the terminal device. At this time, the network device can reselect the parameters based on the previous The above can reduce the reselection parameters corresponding to the second cell so that the second cell is easily selected, and/or increase the reselection parameters corresponding to the first cell on the basis of the previous reselection parameters, so that the first Cells are not easily selected, so the corresponding configuration parameters are allocated to each cell.

S603: The network device sends the first parameter to the terminal device.

Optionally, the network device may broadcast the first parameter to the terminal device by broadcasting, or may send the first parameter to the terminal device through an air interface message. Of course, the first parameter may also be sent to the terminal device in other ways. Here, the embodiment of the present application uses these two sending modes to send the first parameter to the terminal device as an example for description, but it does not mean that the embodiment of the present application is limited to this.

S604. The terminal device determines a reselection parameter corresponding to each cell according to the first parameter, and determines a target cell according to the reselection parameter corresponding to each cell, and reselects to the target cell.

When the terminal device is in the idle state or the deactivated state, the target cell is determined according to the reselection parameter corresponding to each cell, and the target cell is reselected.

It can be seen that when the network device controls the terminal device to determine the target cell according to the reselection parameter determined by the first parameter, it considers the historical network slice information of the terminal device, and determines the correspondence of one or more cells based on the historical network slice information. And send the first parameter to the terminal device so that the terminal device can determine the reselection parameter corresponding to each cell according to the first parameter, and determine the target cell according to the reselection parameter corresponding to each cell to reselect the The target cell can reduce the risk of terminal device access failure and increase the success rate of access.

The embodiments shown in Figure 2 to Figure 6 described in detail in a possible processing manner, the network device or the terminal device determines the target cell according to the historical network slice information of the terminal device, and controls the terminal device to access the target cell The technical solution of the cell will be described in detail below in another possible processing method. After the network device obtains the historical network slice information of the terminal device, if it is determined that the terminal device has a cell ping-pong handover problem, it can further determine the history Whether all the slice types in the network slice information include slice types corresponding to specific types of services, and determine whether the cell ping-pong handover problem needs to be solved according to the judgment result. It should be noted that this possible processing method is executed when the terminal device is in the connected state. For example, please refer to FIG. 7. FIG. 7 is a schematic flowchart of an information processing method provided by an embodiment of this application, and the information processing method may include:

S701. The network device obtains historical network slice information of the terminal device.

It should be noted that the relevant description of the S701 network device acquiring the historical network slice information of the terminal device may refer to the description in the above S301, and the details will not be repeated in this embodiment of the application.

S702. The network device determines a second parameter corresponding to the cell according to historical network slice information.

In this embodiment, the frequency of cell ping-pong handover can be controlled by determining the second parameter.

Wherein, the second parameter may be a mobility parameter corresponding to the cell, so that the terminal device can obtain the mobility parameter corresponding to the cell according to the second parameter; the second parameter may also be an adjustment value of the mobility parameter of the cell, so that the terminal device The mobility parameter corresponding to the adjusted cell can be obtained according to the mobility parameter of the cell and the adjustment value of the mobility parameter of the cell.

In other words, by determining the second parameter corresponding to the cell, the network device is equivalent to determining the mobility parameter corresponding to the cell.

For example, the mobility parameter may include a cell individual offset (Cell Individual Offset, CIO). Of course, it may also include other parameters, which can be specifically set according to actual needs. Here, the embodiment of the present application does not make specific restrictions.

Optionally, when the network device determines the mobility parameter corresponding to the cell based on the historical network slice information, it can configure appropriate mobility parameters for the terminal device according to whether the historical network slice information has network slice information that supports a specific type of service. Among them, a specific type of business may be a business that requires relatively high business continuity. Generally, for a business with relatively high business continuity, the corresponding business level has higher security. For example, a specific type of service may be a safety-related service, such as a video service, a voice service, and so on. If the historical network slicing information contains network slicing information that supports a specific type of service, it indicates that the terminal device has high security requirements for the service level. It is necessary to avoid handover interruption as much as possible. Modifying the mobility parameters of the terminal device may have an impact on business continuity At this time, there is no need to solve the problem of cell ping-pong handover. On the contrary, if there is no network slicing information that supports a specific type of service, it means that the terminal device has low requirements for service continuity. At this time, the mobility parameters of the terminal device can be modified to solve the problem of cell ping-pong handover. It should be noted that when the mobility parameter of the terminal device is modified, the modification is made based on the initial value of the mobility parameter.

It is understandable that when determining whether to solve the problem of cell ping-pong handover, you can also directly determine the services supported by the type of network slice in the historical network slice information, and judge according to the service level of the service. The higher service level can be There is no need to solve the problem of cell ping-pong handover, and the problem of cell ping-pong handover needs to be solved for low service levels.

For example, if the terminal device stays in cell A for a short time and then returns to cell B, it stays in cell B for a short time and then returns to cell A, repeatedly switching between cell A and cell B, or switching When it reaches other cells, the network device can recognize that the terminal device has a cell ping-pong handover. After recognizing that the cell ping-pong handover has occurred in the terminal device, the network device can determine whether to modify the mobility parameter according to the historical network slice information. For example, Enhanced Mobile Broadband (eMBB) services do not have high requirements for business continuity, and mobility parameters of terminal devices can be modified to solve the problem of cell ping-pong handover. For safety-related services, these have high requirements for service continuity. It is necessary to avoid handover interruption as much as possible. Modifying the mobility parameters of terminal equipment may affect service continuity. Therefore, there is no need to solve the problem of cell ping-pong handover.

It can be seen that the information processing method provided in this application, when determining whether to solve the problem of cell ping-pong handover, considers the historical network slice information of the terminal device, and determines whether to solve the cell ping-pong handover according to the historical network slice information of the terminal device In order to solve the problem of cell ping-pong handover, the performance of the service will not be affected.

It should be noted that in the above embodiments, the methods and steps implemented by the terminal device can also be implemented by components (such as chips or circuits) that can be used in the terminal device, and the methods and steps implemented by the network device can also be implemented by the available Implementation of components (such as chips or circuits) in network equipment.
