Before describing the technical solution provided by the embodiment of the present application in detail, a concept of Network Slice Information related in the present application is introduced, where the Network Slice Information may include Network Slice Selection Assistance Information (NSSAI), and the NSSAI includes one or more Single Network Slice Selection Assistance Information (S-NSSAI). As can be seen from fig. 2, the S-NSSAI is composed of two parts, namely, a Slice/Service type (SST) and a Slice Differentiator (SD), where SST occupies 8 bits and SD occupies 24 bits, and SST is an expected network Slice behavior in terms of function and Service; SD is optional information to distinguish multiple network slices of the same slice/service type.

The identification information of the historical serving cell comprises at least one of identification information of a historical serving cell identification, identification information of a registration area to which the historical serving cell belongs, or identification information of a tracking area to which the historical serving cell belongs.

Further, for each of the three pieces of historical network slice information, the type of the historical network slice information may include at least one of activated network slice information, allowed network slice information, or network slice information of interest.

In detail, the type of the historical network slice information may include only any one type of the activated network slice information, the allowed network slice information, or the network slice information of interest, or may include any two types of the activated network slice information, the allowed network slice information, or the network slice information of interest, and of course, may also include three types of the activated network slice information, the allowed network slice information, or the network slice information of interest, where the embodiment of the present application is only described as an example that the historical network slice information may include at least one of the activated network slice information, the allowed network slice information, or the network slice information of interest, but does not represent that the embodiment of the present application is limited thereto.

Taking historical network slice information as historical network slice information of a historical serving cell of the terminal device, and taking the example that the type of the historical network slice information is activated network slice information, the historical network slice information acquired by the network device is the activated network slice information of the historical serving cell.

Or, taking historical network slice information as historical network slice information in a registration area to which a historical serving cell of the terminal device belongs and historical network slice information in a tracking area to which the historical serving cell of the terminal device belongs, and the types of the historical network slice information may include activated network slice information, allowed network slice information, and network slice information of interest, for example, then the historical network slice information acquired by the network device includes activated network slice information, allowed network slice information, and network slice information of interest in the registration area to which the historical serving cell belongs, and activated network slice information, allowed network slice information, and network slice information of interest in the tracking area to which the historical serving cell belongs.

After the historical network slice information of the terminal device is acquired, the network device can perform processing according to the historical network slice information. It should be noted that, in the embodiment of the present application, for a network device, processing according to historical network slice information of a terminal device may include at least the following three possible processing manners:

1. the network device may control the terminal device to access to a target cell according to the historical network slice information of the terminal device, where the target cell is one of at least one candidate cell, and the candidate cell may be determined according to at least one of network slice information supported by the cell and signal strength of the cell.

2. After the network device obtains the historical network slice information of the terminal device, the network device can also judge whether all slice types in the historical network slice information include a slice type corresponding to a specific type service, and determine whether the problem of cell ping-pong handover needs to be solved according to the judgment result.

3. After acquiring the historical network slice information of the terminal device, the network device may further send the historical network slice information of the terminal device to another network device (for example, may be referred to as a first network device), so that the first network device may perform processing according to the historical network slice information. Such as a store process or a forward process. The first network device may be a network device to which the target cell belongs, or may be another network device.

It can be understood that the processing according to the historical network slice information of the terminal device may further include other possible processing manners, and here, the embodiment of the present application is only described by taking the three possible processing manners as examples, but does not represent that the embodiment of the present application is only limited thereto. The first possible processing manner and the second possible processing manner will be described in detail below by way of detailed embodiments.

For example, please refer to fig. 3, where fig. 3 is a flowchart illustrating an information processing method according to an embodiment of the present application, in which a network device may determine candidate cells according to historical network slice information of the terminal device, the information processing method may include:

s301, the network equipment acquires historical network slice information of the terminal equipment.

Wherein the historical network slice information comprises an identification of the historical network slice. For example, the identifier of the historical network slice may be a serial number of the historical network slice, or may also be a service type supported by the historical network slice, and of course, other identifiers may also be used.

Optionally, the historical network slice information may be recorded in the mobility history information (UE mobility history information) of the terminal itself by the terminal device, or may also be recorded in the mobility history information (UE mobility history information) of the terminal itself by the network device, where the mobility history information includes information of a cell, historical network slice information, time of staying (state) in the cell, and the like.

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

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

For example, the first message may be an air interface message, where the air interface message may be an existing 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, and the embodiment of the present application is not limited herein. For example, each time a terminal device accesses one serving cell, the terminal device may record at least one of network slice information in the corresponding serving cell, network slice information in a registration area to which the corresponding serving cell belongs, or network slice information in a tracking area to which the corresponding serving cell belongs as historical network slice information, and carry the recorded historical network slice information in a first message at a certain time to send to the network device, so that the network device obtains the historical network slice information of the terminal device.

In another possible implementation, the network device may receive a second message from a second network device; after receiving the second message, the network device may obtain historical network slice information of the terminal device according to the historical network slice information of the terminal device included in the second message. The second network device is a network device for recording historical network slice information of the terminal device, and the network device performs cell switching control processing or solves the problem of cell ping-pong switching according to the network slice information of the current cell and the recorded historical network slice information, or sends 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, controlling cell handover processing, solving a cell ping-pong handover problem, or sending the acquired historical network slice information of the terminal device to other network devices.

For example, the second message may be a context acquisition message, a handover request message, or may also be a newly defined X2/Xn interface message, which is not limited herein in the embodiments of the present application. For the second network device, each time the terminal device accesses one serving cell, the network device will use at least one of 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 network slice information in the tracking area to which the corresponding serving cell belongs as a history network slice information record, and carry the history network slice information in the second message to send to the network device, so that the network device can obtain the history network slice information of the terminal device.

For example, the historical network slice information of the terminal device is recorded by the second network device, and the historical network slice information is sent to the network device, that is, the network device obtains the historical network slice information of the terminal device from the second network device, and of course, the historical network slice information of the terminal device may also be recorded by the terminal device or the core network device.

The activated network slice information is an S-NSSAI corresponding to all protocol data unit sessions (PDU sessions), and the S-NSSAI corresponding to all PDU sessions may form an S-NSSAI list, which may also be referred to as NSSAI. 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, it may also record the registration area information corresponding to the activated network slice information in the historical network slice information of the terminal device, and of course, it may also record the tracking area information corresponding to the activated network slice information in the historical network slice information of the terminal 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 the network slice information to the second network device through an initial context setup (initial context setup) message, and the second network device records the network slice information as allowed network slice information into the historical network slice information of the terminal device, so that the network device may 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, the serving cell information corresponding to the allowed network slice information may also be recorded in the historical network slice information of the terminal device, optionally, the registration area information corresponding to the allowed network slice information may also be recorded in the historical network slice information of the terminal device, and of course, the tracking area information corresponding to the allowed network slice information may also be recorded in the historical network slice information of the terminal device.

The network slice information of interest may be sent by the terminal device to the core network device through the second network device in a process in which 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 the registration request message, and the second network device records the network slice information as the network slice information of interest into the historical network slice information of the terminal device and sends the network slice information to the core network device. For example, the terminal device may send a slice List (S-NSSAI-List) to the second network device via a radio resource control setup complete (RRC setup complete) message, so that the second network device records the slice List and forwards the slice List to the core network device after receiving the slice List. The slice list is network slice information requested by the terminal device, and the slice information requested by the terminal device can be understood as network slice information of interest to the terminal device. That is, the second network device records the network slice information of interest and records the network slice information of interest into the historical network slice information of the terminal device, so that 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 network slice information of interest in the historical network slice information of the terminal device, the serving cell information corresponding to the network slice information of interest may also be recorded in the historical network slice information of the terminal device, optionally, the registration area information corresponding to the network slice information of interest may also be recorded in the historical network slice information of the terminal device, and of course, the tracking area information corresponding to the network slice information of interest may also be 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) may be configured in advance for the terminal device, may also be slice information that is actually interested by the terminal device, or may also be slice information that is allowed to be supported by the terminal device in the last registration domain, of course, other slice information may also be used, and the embodiment of the present application is not limited specifically herein.

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

For example, the third message may be an interface message, which may be an existing NG interface message, an existing S1 interface message, or a newly defined interface message, and the present application is not limited herein. For the core network device, each time the terminal device accesses one serving cell, the core network device will take at least one of 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 network slice information in the tracking area to which the corresponding serving cell belongs as a history network slice information record, and carry the history network slice information in a third message to send to the network device, so that the network device can obtain the history network slice information of the terminal device.

It should be noted that, when the network history slice information is obtained in S301, the above three possible implementation manners may be further combined, that is, any two or three of the first message, the second message and the third message may be used to obtain the network history slice information, this embodiment of the present application is only described by taking the above three possible implementation manners as examples, and of course, the historical network slice information of the terminal device may also be obtained from other devices or apparatuses or modules (for example, a centralized node device).

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

and S302, the network equipment controls the terminal equipment to access to 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 to which the terminal device has previously accessed, and of course, the target cell may also be a new cell, that is, a cell to which the terminal device has not previously accessed.

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

Therefore, according to the information processing method provided by the embodiment of the application, after the network device obtains the historical network slice information of the terminal device, the network device can be controlled to access the target cell according to the historical network slice information, so that the risk of access failure of the terminal device can be reduced, and the success rate of access can be improved. It is to be understood that, when determining the target cell, besides the historical network slice information, other information, such as signal strength of the cell, etc., may be considered, which is not limited in the embodiments of the present application.

It should be noted that, in the above S302, when the network device controls the terminal device to access the target cell according to the historical network slice information, if the current state of the terminal device is different, the corresponding manner in which the network device controls the terminal device to access the target cell 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, how the network device controls the terminal device to access to the target cell according to the historical network slice information in the three different states will be described in detail for the three different states.

When the terminal device is in a connected state, for example, please refer to fig. 4, where fig. 4 is a schematic flow diagram of another information processing method provided in the embodiment of the present application, and the information processing method may include:

s401, the network equipment acquires historical network slice information of the terminal equipment.

Wherein the historical network slice information comprises an identification of the historical network slice. Optionally, the historical network slice information may be recorded in the mobile history information (UE mobility history information) of the terminal itself by the terminal device, or may also be recorded in the mobile history information (UE mobility history information) of the terminal itself by the network device.

Optionally, the type of the historical network slice information includes at least one of: for the activated network slice information, the allowed network slice information, or the interested network slice information, reference may be specifically made to the relevant description in S301 above, and here, the embodiments of the present application are not described again.

It should be noted that, when the terminal device is in the connected state, the network device may obtain the historical network slice information of the terminal device through the first message, the second message, or the third message, and of course, may also obtain the historical network slice information of the terminal device through other manners, and a specific obtaining manner may refer to the relevant description in S301 above, where this embodiment of the present application is not particularly limited.

After acquiring the historical network slice information of the terminal device, the network device may execute the following S402:

s402, the network equipment determines a target cell according to the historical network slice information.

The historical network slice information comprises the identification of the historical network slice.

In one possible approach, the network device may determine a target cell among the at least one candidate cell. Optionally, the target cell may be determined by a preset condition, for example, a cell meeting the preset condition is determined as the target cell. Wherein, the preset condition can be understood as: the slice types in the historical network slice information of the cell comprise the current slice types of the terminal equipment as much as possible, and the current signal strength of the cell is greater than a first threshold value. The current slice type of the terminal device refers to the slice type of the terminal device under the 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 slice types in the historical network slice information of the candidate cell include the current slice type of the terminal device, and the signal strength of the candidate cell is greater than the first threshold, at this time, the candidate cell may be determined as the target cell.

It should be noted that, if more than one candidate cell satisfies the preset condition, the target cell may be determined by further combining other factors, or one cell may be randomly or arbitrarily selected as the target cell from the cells satisfying the preset condition. For example, in the case that more than one candidate cell satisfies the preset condition, the target cell may be further determined among the plurality of candidate cells according to the priority of the slice type in the historical network information of the cell satisfying the preset condition. For example, the candidate cell corresponding to the slice type with the higher priority may be determined as the target cell, or one cell among a plurality of cells may be randomly selected and determined as the target cell.

When the target cell meeting the preset condition is determined according to the historical network slice information, the target cell meeting the preset condition can 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 present application, and it can be seen from fig. 5 that signal strengths of neighboring cells measured by a terminal device are: reference Signal Receiving Power (RSRP) of a first cell is-110 dbm, and the first cell is a cell under the network device 1; the RSRP of the second cell is-90 dbm, the RSRP of the third cell is-100 dbm, the second cell and the third cell are cells under the network device 2, and the slice types of the second cell in the historical network slice information are S-NSSAI1 and S-NSSAI2, 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, because the number of the current slice types of the terminal device supported by the third cell is the largest, and the RSRP of the third cell is greater than the first threshold, the signal strength of the third cell may be determined as a target cell, so as to satisfy the service corresponding to the current network slice information of the terminal device as much as possible.

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

S403, the network equipment sends the configuration information of the target cell to the terminal equipment.

S404, the terminal device is switched to the target cell according to the configuration information of the target cell.

Therefore, when the network equipment determines the target cell, the historical network slice information of the terminal equipment is considered, the target cell is determined according to the historical network slice information of the terminal equipment and the current slice information of the terminal equipment, the target cell is determined through the network equipment, and the terminal equipment is controlled to be accessed to the target cell through the configuration information, so that the risk of access failure can be reduced, and the success rate of access is improved.

For example, please refer to fig. 6, where fig. 6 is a schematic flowchart of another information processing method provided in the embodiment of the present application, and the information processing method may include:

s601, the network equipment acquires historical network slice information of the terminal equipment.

Optionally, corresponding to the terminal device in the idle state, the type of the historical network slice information includes at least one of the following: allowed network slice information or network slice information of interest. When obtaining the historical network slice information, the network device may obtain the historical network slice information of the terminal device through the first message, and of course, may also obtain the historical network slice information of the terminal device through other manners, and a specific obtaining manner may refer to the related description in S301 above, and herein, the embodiment of the present application is not limited specifically. It is to be understood that the network device may receive the historical network slice information of the terminal device through the first message after the terminal device in the idle state transitions to the connected state.

Optionally, when the idle-state terminal device and the deactivated-state terminal device record the historical network slice information, the historical network slice information of the terminal device may also be recorded in a Minimization of Drive Test (MDT) log, which is not limited herein in the embodiment of the present application.

And the terminal equipment corresponds to a deactivated state, wherein the type of the historical network slice information comprises at least one of the following types: active network slice information, allowed network slice information, or network slice information of interest. When obtaining the historical network slice information, the network device may obtain the historical network slice information of the terminal device through the first message, the second message, or the third message, and of course, may also obtain the historical network slice information of the terminal device through other manners, and a specific obtaining manner may refer to the related description in S301 above, and herein, the embodiment of the present application is not limited specifically. It is to be understood that the network device may receive the historical network slice information of the terminal device through the first message after the terminal device in the deactivated state is converted into the connected state.

For example, if the current serving cell of the terminal device belongs to the second network device, the second network device may record the network slice information of the terminal device and record the network slice information in the historical network slice information, and optionally, the terminal device may also record the network slice information of the terminal device and record the network slice information in the historical network slice information. Then, the terminal device enters a deactivated state under the second network device, the terminal device moves to the network device, initiates a radio resource connection recovery (RRC resume) procedure to a cell under the network device, and connects to a serving cell under the second network device, at this time, the network device may initiate a terminal context acquisition (retrieve UE context) procedure 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 a context acquisition message; optionally, the historical network slice information of the terminal device may also be sent to the network device through an RRC resume flow.

After acquiring the historical network slice information of the terminal device, the network device may execute the following S602:

s602, the network equipment determines a first parameter corresponding to one or more cells according to the slice information supported by the cells in the historical network slice information.

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

That is, the network device determines the first parameter corresponding to each cell, that is, determines the reselection parameter corresponding to each cell.

For example, the reselection parameter may include a bias parameter (e.g., Qoffset) of the cell, and of course, may also include other parameters, which may be specifically set according to an actual need, and herein, the embodiment of the present application is not specifically limited. When determining reselection parameters corresponding to one or more cells according to slice information supported by the cells in the historical network slice information, if a slice type in the network slice information supported by a certain cell includes a slice type required by the terminal device, it may be determined that the reselection parameters corresponding to the cell are configured to be relatively low, so that the cell is easier to reselect; 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 may be determined that the reselection parameter corresponding to the cell is configured relatively high, so that the cell is not easily reselected, thereby improving the selection efficiency of the target cell. The slice type required by the terminal device may be understood as a slice type corresponding to a service supported by the terminal device. That is, it may 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 may be implemented at the same time or alternatively. In one possible approach, the configuration of the reselection parameter for a cell may be based on an adjustment of the previous reselection parameter. It can be understood that, in the embodiment of the present application, there is no limitation on the adjustment direction of the reselection parameter, and different parameters may have different adjustment directions, as long as a suitable cell is easier to reselect and an unsuitable cell is not easier to select.

For example, if the slice type in the historical network slice information of the first cell is NSSAI1, NSSAI2, and NSSAI3, and the slice type in the historical network slice information of the second cell is NSSAI2, NSSAI3, NSSAI4, and NSSAI5, and the current slice type of the terminal device is a network slice 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 may decrease the reselection parameter corresponding to the second cell on the basis of the previous reselection parameter so that the second cell is easily selected, and/or increase the reselection parameter corresponding to the first cell on the basis of the previous reselection parameter so that the first cell is not easily selected, thereby allocating the corresponding configuration parameter to each cell.

S603, the network equipment sends the first parameter to the terminal equipment.

Optionally, the network device may broadcast the first parameter to the terminal device by a broadcast method, or may send the first parameter to the terminal device by an air interface message, or may send the first parameter to the terminal device by other methods.

S604, the terminal device determines reselection parameters corresponding to the cells according to the first parameters, determines a target cell according to the reselection parameters corresponding to the cells, and reselects the target cell.

And when the terminal equipment is in an idle state or a deactivated state, determining a target cell according to the reselection parameters corresponding to the cells, and reselecting the target cell.

Therefore, when the network device controls the terminal device to determine the target cell according to the reselection parameter determined by the first parameter, the historical network slice information of the terminal device is considered, the first parameter corresponding to one or more cells is determined according to the historical network slice information, and the first parameter is sent 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 target cell, thereby reducing the risk of access failure of the terminal device and improving the success rate of access.

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

s701, the network equipment acquires historical network slice information of the terminal equipment.

It should be noted that, for the description of the step S701 in which the network device acquires the historical network slice information of the terminal device, reference may be made to the description in the step S301, and details are not repeated in this embodiment of the present application.

S702, the network equipment determines a second parameter corresponding to the cell according to the historical network slice information.

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

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

That is, the network device determines the second parameter corresponding to the cell, that is, the mobility parameter corresponding to the cell.

For example, the mobility parameter may include a Cell Individual Offset (CIO), and of course, may also include other parameters, which may be specifically set according to actual needs, and herein, the embodiment of the present application is not specifically limited.

Optionally, when the network device determines the mobility parameter corresponding to the cell according to the historical network slice information, the network device may configure an appropriate mobility parameter for the terminal device according to whether the historical network slice information has network slice information supporting a specific type of service. The specific type of service may be a service with a relatively high requirement on service continuity, and in general, the security of the corresponding service level is relatively high for a service with a relatively high service continuity. For example, the specific type of service may be a security (safety) -related service, a video service, a voice service, and the like. If the historical network slice information has network slice information supporting a specific type of service, it indicates that the terminal device has a high requirement on the security of the service level, and if switching interruption is to be avoided as much as possible, modifying the mobility parameter of the terminal device may have an influence on service continuity, and at this time, the problem of cell ping-pong switching may not be solved. On the contrary, if there is no network slice information supporting a specific type of service, it indicates that the terminal device has low requirements for service continuity, and at this time, the mobility parameter of the terminal device may be modified to solve the problem of cell ping-pong handover. When modifying the mobility parameter of the terminal device, the modification is performed based on the initial value of the mobility parameter.

It can be understood that, when determining whether to solve the problem of cell ping-pong handover, the service supported by the cell ping-pong handover can be determined directly according to the type of the network slice in the historical network slice information, and the determination is made according to the service level of the service, and the service level is high, so that the problem of cell ping-pong handover does not need to be solved, and the service level is low, so that the problem of cell ping-pong handover needs to be solved.

For example, if the terminal device stays in the cell a for a short time and then returns to the cell B, stays in the cell B for a short time and returns to the cell a, and repeatedly switches between the cell a and the cell B, or switches to another cell, the network device may recognize that the terminal device has undergone cell ping-pong handover. After recognizing that the terminal device performs cell ping-pong handover, the network device may determine whether to modify the mobility parameter according to the historical network slice information. For example, Enhanced Mobile Broadband (eMBB) service has low requirement on service continuity, and may modify the mobility parameter of the terminal device to solve the problem of cell ping-pong handover. For the safety-related services, these services have high requirements on service continuity, and to avoid handover interruption as much as possible, modifying the mobility parameter of the terminal device may have an influence on the service continuity, so that it may not be necessary to solve the problem of cell ping-pong handover.

Therefore, when determining whether the problem of cell ping-pong handover is solved, the information processing method provided by the application considers the historical network slice information of the terminal device and determines whether the problem of cell ping-pong handover is solved according to the historical network slice information of the terminal device, so that the performance of the service is not affected when the problem of cell ping-pong handover is solved.

It should be noted that, in the above embodiments, the method and the step implemented by the terminal device may also be implemented by a component (e.g., a chip or a circuit) available for the terminal device, and the method and the step implemented by the network device may also be implemented by a component (e.g., a chip or a circuit) available for the network device.
