Description

Information processing method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information processing method and apparatus.

Background

Networking modes of a fifth generation mobile communication technology (5 g) network include non-independent Networking (NSA), independent networking (SA), and mixed networking of SA and NSA.

When the IDLE (IDLE) state terminal device supporting the SA performs cell reselection or cell redirection, the acquired New Radio (NR) frequency point may be an NSA frequency point, an SA frequency point, or a mixed networking frequency point of the SA and the NSA. After the IDLE-state terminal device supporting the SA acquires the NR frequency point, it is further required to determine whether an NR cell to which the NR frequency point belongs supports the SA.

If the frequency point of the NR cell is an SA frequency point or a mixed networking frequency point of the SA and the NSA, the NR cell supports the SA, and the IDLE terminal equipment supporting the SA can reselect or redirect to the NR cell; if the frequency point of the NR cell is an NSA frequency point, the NR cell does not support the SA, and the terminal device further needs to perform the above-described decision operation for the next NR frequency point, so that the duration of cell reselection or cell redirection by an IDLE-state terminal device supporting the SA is extended. For the IDLE terminal device supporting the SA, how to avoid prolonging the time required for cell reselection or cell redirection is an urgent problem to be solved.

Disclosure of Invention

The embodiment of the application provides an information processing method and an information processing device, which can avoid the time length extension required for cell reselection or cell redirection for an IDLE (IDLE) state terminal device supporting an independent network (SA).

In a first aspect, the present application provides an information processing method, which is executed by a first network device or a module in the first network device. The method comprises the following steps: the first network equipment determines that the first frequency point is an independent networking frequency point or a mixed networking frequency point of independent networking and non-independent networking according to the switching information of the first frequency point; and the first network equipment sends a system message or a redirection message carrying the identifier of the first frequency point in the first cell.

The switching information of the first frequency point comprises: the information that the terminal equipment accessed to the first cell is successfully switched from the first cell to the second cell and/or the information that the terminal equipment accessed to the second cell is successfully switched from the second cell to the first cell; the first network device is a network device to which the first cell belongs, the frequency point of the second cell is a first frequency point, and the second cell is a New Radio (NR) cell.

As can be seen, in the information processing method, the first frequency point transmitted by the system message or the redirection message is the frequency point of the cell supporting the SA, so that when the idle terminal device supporting the SA performs cell reselection based on the system message or performs cell redirection based on the redirection message, it is not necessary to perform operations such as decision and the like due to the fact that the transmitted frequency point may be a non-independent Networking (NSA) frequency point, thereby avoiding prolonging the time required for cell reselection or redirection.

In addition, in the method, the first network device determines that the first frequency point is an SA frequency point or a mixed networking frequency point of SA and NSA, instead of an NSA frequency point, according to the switching information of the first frequency point, and compared with a mode of manually marking whether the frequency point is an NSA frequency point to filter the NSA frequency point, the method can avoid increasing workload and complexity of manual operation and maintenance. In addition, the method can avoid the possible misjudgment risk in configuration identification due to the manual marking and filtering of the NSA frequency point mode.

In an optional implementation manner, the information that the terminal device accessing the first cell successfully switches from the first cell to the second cell includes the number of times of receiving the first signaling; the receiving times of the first signaling are larger than or equal to a first threshold value. The first signaling is received by the first network equipment and used for indicating the signaling that the terminal equipment accessing the first cell is successfully switched from the first cell to the second cell. As can be seen, in this embodiment, the first network device may determine, according to the first signaling, that the terminal device accessing the first cell is successfully handed over from the first cell to the second cell, that is, the second cell supports the terminal device to access or camp on, so that the frequency point of the second cell (that is, the first frequency point) is an SA frequency point or a mixed networking frequency point of SA and NSA.

In this embodiment, in one case, the switching information of the first frequency point is the receiving frequency of the first signaling, and then, when the receiving frequency of the first signaling is greater than or equal to a first threshold, the first network device determines that the first frequency point is an independent networking frequency point or a mixed networking frequency point of an independent networking and a non-independent networking, and issues the first frequency point in a system message or a redirection message; and when the receiving times of the first signaling are smaller than a first threshold value, the first network equipment does not issue the first frequency point in the system message or the redirection message.

In an optional implementation manner, the information that the terminal device accessing the first cell successfully switches from the first cell to the second cell includes: the switching success rate of the terminal equipment accessed to the first cell for switching from the first cell to the second cell; wherein the handover success rate is greater than or equal to the second threshold. In this embodiment, the first network device may determine that the first frequency point is an SA frequency point or a mixed networking frequency point of SA and NSA according to a handover success rate of a terminal device accessing the first cell to handover from the first cell to the second cell, which is beneficial to improving an identification accuracy rate of the first frequency point being an SA frequency point or the first frequency point being a mixed networking frequency point of SA and NSA.

In this embodiment, in one case, the switching information of the first frequency point is a switching success rate of the terminal device accessing the first cell switching from the first cell to the second cell, and then, when the switching success rate is greater than or equal to the second threshold, the first network device determines that the first frequency point is an independent networking frequency point or a mixed networking frequency point of an independent networking and a non-independent networking, and issues the first frequency point in the system message or the redirection message; and when the switching success rate is smaller than the second threshold value, the first network equipment does not issue the first frequency point in the system message or the redirection message.

In this embodiment, the handover success rate may be determined according to the number of times of sending the second signaling and the number of times of receiving the first signaling; the second signaling is signaling sent by the first network device and used for requesting to switch the terminal device accessing the first cell from the first cell to the second cell.

In an optional implementation manner, the information that the terminal device accessing the second cell successfully switches from the second cell to the first cell includes: and switching the successful times from the second cell to the first cell by the terminal equipment accessing the second cell, wherein the successful times of switching is greater than or equal to a third threshold value. In this embodiment, the first network device may determine that the second cell supports the terminal device to access or camp on according to the number of times that the terminal device accessing the second cell is successfully switched from the second cell to the first cell, and further may determine that the frequency point (i.e., the first frequency point) of the second cell is an SA frequency point or a mixed networking frequency point of SA and NSA.

In this embodiment, in one case, the switching information of the first frequency point is the number of times that the terminal device accessing the second cell successfully switches from the second cell to the first cell, then, when the number of times that the terminal device accessing the second cell successfully switches from the second cell to the first cell is greater than or equal to a third threshold, the first network device determines that the first frequency point is an independent networking frequency point or a mixed networking frequency point of an independent networking and a non-independent networking, and issues the first frequency point in a system message or a redirection message; and when the number of times of successful switching from the second cell to the first cell by the terminal equipment accessed to the second cell is less than a third threshold value, the first network equipment does not issue the first frequency point in the system message or the redirection message.

In an optional implementation manner, the switching information of the first frequency point is determined by the first network device within a preset time period. In this embodiment, the first network device may count the switching information of the first frequency point within a preset time period, so that the real-time performance of the counted switching information of the first frequency point is better, and the improvement of the identification accuracy that the first frequency point is an SA frequency point or a mixed networking frequency point of SA and NSA is facilitated.

In this embodiment, the first network device may start a timer, and count the switching information of the first frequency point; and the first network equipment executes the step of determining that the first frequency point is an independent networking frequency point or a mixed networking frequency point of independent networking and non-independent networking according to the switching information of the first frequency point when the timer is over time. Therefore, the switching information of the first frequency point obtained in the embodiment can better reflect the actual situation of the first frequency point at present, and is beneficial to improving the identification accuracy of the first frequency point being an SA frequency point or a mixed networking frequency point of the SA and NSA.

In a second aspect, the present application provides an information processing method, which is executed by a terminal device or a module in the terminal device. The method comprises the following steps: the terminal equipment receives a system message or a redirection message which comes from first network equipment and carries the identification of the first frequency point; the first frequency point is an independent networking frequency point, or the first frequency point is a mixed networking frequency point of independent networking and non-independent networking; and the terminal equipment reselects or redirects to the second cell according to the identifier of the first frequency point.

The first frequency point is an independent networking frequency point, or the first frequency point is a mixed networking frequency point of independent networking and non-independent networking, and is determined based on the switching information of the first frequency point; wherein, the switching information of the first frequency point comprises: the information that the terminal equipment accessed to the first cell is successfully switched from the first cell to the second cell and/or the information that the terminal equipment accessed to the second cell is successfully switched from the second cell to the first cell; the first network device is a network device to which the first cell belongs, the frequency point of the second cell is a first frequency point and the second cell is a new wireless NR cell.

Therefore, in the information processing method, the first frequency point sent by the system message or the redirection message is the frequency point of the cell supporting the SA, so that when the idle terminal device supporting the SA performs cell reselection based on the system message or performs cell redirection based on the redirection message, operations such as decision execution and the like are not required because the sent frequency point may be an NSA frequency point, thereby avoiding prolonging the time required by cell reselection or redirection.

In addition, in the method, the first frequency point is an SA frequency point, or the first frequency point is a mixed networking frequency point of SA and NSA, but not an NSA frequency point, and is determined based on the switching information of the first frequency point, and compared with a mode that whether the frequency point is the NSA frequency point or not is manually marked to filter the NSA frequency point, the workload and the complexity of manual operation and maintenance can be avoided being increased. In addition, the method can avoid the possible misjudgment risk in configuration identification due to the manual marking and filtering of the NSA frequency point mode.

In an optional implementation manner, the information that the terminal device accessing the first cell successfully switches from the first cell to the second cell includes the number of times of receiving the first signaling; receiving a first signaling, wherein the receiving times of the first signaling are greater than or equal to a first threshold; the first signaling is received by the first network device and used for indicating the terminal device accessing the first cell to be successfully switched from the first cell to the second cell. As can be seen, in this embodiment, it can be determined that the terminal device accessing the first cell is successfully handed over from the first cell to the second cell according to the first signaling, that is, the second cell supports the terminal device to access or camp on, so that the frequency point (i.e., the first frequency point) of the second cell is an SA frequency point or a mixed networking frequency point of SA and NSA. Then, the idle state terminal device supporting the SA may reselect or redirect to the second cell.

In this embodiment, the first frequency point is an SA frequency point, or the first frequency point is a mixed networking frequency point of SA and NSA, which may be determined according to a switching success rate of a terminal device accessing the first cell switching from the first cell to the second cell, and is beneficial to improving an identification accuracy rate of the mixed networking frequency point where the first frequency point is an SA frequency point, or the first frequency point is an SA and NSA.

In an optional implementation manner, the information that the terminal device accessing the second cell successfully switches from the second cell to the first cell includes: and the number of times of successful switching from the second cell to the first cell by the terminal equipment accessing the second cell is greater than or equal to a third threshold value. In this embodiment, it may be determined that the second cell supports the access or camping of the terminal device according to the number of times that the terminal device accessing the second cell is successfully switched from the second cell to the first cell, and therefore the frequency point (i.e., the first frequency point) of the second cell is an SA frequency point or a mixed networking frequency point of SA and NSA. Then, the idle state terminal device supporting the SA may reselect or redirect to the second cell.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present disclosure. The communication system may include, but is not limited to, a network device and a terminal device. The communication system also includes a channel for transmitting data between the network device and the terminal device, such as a transmission medium such as an optical fiber, a cable, or the atmosphere.

To facilitate understanding of the embodiments disclosed herein, the following two descriptions are made.

(1) In the embodiment disclosed in the present application, a scenario of an NR network in a wireless communication network is taken as an example for description, and it should be noted that the solution in the embodiment disclosed in the present application may also be applied to other wireless communication networks, and corresponding names may also be replaced by names of corresponding functions in other wireless communication networks.

(2) Embodiments disclosed herein will present various aspects, embodiments, or features of the application in the context of a system comprising a plurality of devices, components, modules, etc. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. Furthermore, a combination of these schemes may also be used.

Next, a brief description will be given of related concepts related to the embodiments of the present application.

1. System messages and redirect messages

The system message is a message periodically sent by the network device. The system message may be used for the terminal device to obtain information such as access information, cell selection, or common configuration parameters for cell reselection. For example, the system message may be used for the terminal device to acquire the relevant configuration information of the current serving cell, and may also be used for the terminal device to acquire the relevant configuration information of the neighboring cell.

The system message may be divided into a Master Information Block (MIB) and a System Information Block (SIB). Each system message contains a set of parameters associated with a function. For example, in an LTE network, the SIB24 sent by the network device contains information related to inter-system cell reselection. When the inter-system is an NR system, the SIB24 includes information of an NR frequency point and NR neighbor information related to cell reselection. For another example, in the NR network, SIB3 and/or SIB4 transmitted by the network device includes information of NR frequency points related to cell reselection.

In addition, the system message is a cell-level message, that is, for a system message sent by a network device to which a certain cell belongs in the cell, all terminal devices accessing the cell can receive and use the system message.

The redirection message is a message issued by the network device when the terminal device performs cell redirection, so that the terminal device can perform cell redirection according to the redirection message.

2. Dependent networking (non standalone, NSA)

In the networking mode of the 5G network, NSA is a networking mode in which NR network deployment is performed on the infrastructure of an LTE network. The NSA can realize the rapid deployment of the NR network and is suitable for the initial stage of the deployment of the NR network. Also, in NSA, LTE network devices and NR network devices may coexist. The frequency point of the cell managed by the LTE network device is an LTE frequency point, and the frequency point of the cell managed by the NR network device is a non-independent networking frequency point (i.e., an NSA frequency point).

As shown in fig. 2a, the core network in NSA is an LTE core network, i.e. an Evolved Packet Core (EPC) (or EPC +). The LTE network equipment and the equipment in the LTE core network can transmit control signaling and user data, and the LTE network equipment and the NSA-supporting terminal equipment can both transmit control signaling and user data. User data may be transmitted between the NR network device and a device in the LTE core network, and user data may be transmitted between the NR network device and a terminal device supporting NSA. In addition, if control signaling needs to be transmitted between the NR network device and the device in the LTE core network, the LTE network device needs to be used as an intermediate device (anchor point) for transmission.

As can be seen, in NSA, the terminal device may directly access or camp on the LTE cell managed by the LTE network device, that is, the terminal device may access the LTE cell through cell search, cell selection, and random access processes. The terminal device cannot access and camp on the NR cell managed by the NR network device. That is to say, when the frequency point of the NR cell is an NSA frequency point, the NR cell cannot support the terminal device to access and camp on.

In the application, the LTE network refers to a 4G network, and the NR network refers to a 5G network. The LTE network device refers to a 4G network device, and the NR network device refers to a 5G network device.

3. Independent networking (standalon, SA)

In the networking mode of the 5G network, SA is a networking mode in which an NR network is independently established, and the network devices in the networking mode are NR network devices, and the core network is an NR core network, that is, a 5G core network (5G core, 5gc). The frequency point of the cell managed by the NR network device is an independent networking frequency point (i.e., an SA frequency point). In addition, the SA supports 5G end-to-end network slicing, and diversified services can be customized according to different types of application scenes or different user requirements.

As shown in fig. 2b, in the SA, control signaling and user data may be transmitted between the NR network device and a device in the NR core network, and control signaling and user data may be transmitted between the terminal devices supporting the SA. It can be seen that the terminal device supporting SA can directly access or camp on the NR cell managed by the NR network device, i.e. the terminal device supporting SA can access the NR cell through cell search, cell selection and random access procedures. That is to say, when the frequency point of the NR cell is an SA frequency point, the NR cell supports access or camping of the terminal device.

Hybrid networking of SA and NSA

In the networking mode of the 5G network, the network devices in the hybrid networking of SA and NSA include LTE network devices and NR network devices, and the core network includes an LTE core network and an NR core network. As shown in fig. 2c, the hybrid networking of SA and NSA differs from NSA in that: the NR network device in the hybrid networking of SA and NSA may transmit control data and user data with the device in the NR core network, and may transmit control data and user data with the terminal device supporting SA, in addition to user data with the device in the LTE core network. In addition, in the mixed networking of SA and NSA, the frequency point of the cell managed by the NR network device is a mixed networking frequency point of an independent networking and a non-independent networking (i.e., a mixed networking frequency point of SA and NSA).

In the hybrid networking of the SA and the NSA, the terminal equipment can select to access an LTE cell managed by the LTE network equipment or an NR cell managed by the NR network equipment according to the self capacity. Wherein, the terminal device supporting only NSA, the terminal device supporting only SA, and the terminal device supporting SA and NSA can all access or camp on the NR cell managed by the NR network device. That is, when the frequency point of the NR cell is a mixed networking frequency point of the SA and the NSA, the NR cell supports access or camping of the terminal device.

The IDLE (IDLE) state terminal device supporting the SA refers to a terminal device supporting the SA and in an IDLE state. The idle-state terminal device supporting the SA may be an idle-state terminal device supporting only the SA or an idle-state terminal device supporting the SA and the NSA.

When the idle terminal device supporting the SA performs cell reselection or cell redirection, the acquired NR frequency point may be an NSA frequency point, an SA frequency point, or a mixed networking frequency point of the SA and the NSA. If the frequency point of the NR cell is an SA frequency point or a mixed networking frequency point of SA and NSA, the NR cell supports the SA; if the frequency point of the NR cell is the NSA frequency point, the NR cell does not support the SA. Then, after acquiring the NR frequency point, the idle terminal device supporting the SA needs to determine whether an NR cell to which the NR frequency point belongs supports the SA.

With reference to fig. 3, after the idle terminal device supporting the SA searches for the NR frequency, it needs to perform downlink synchronization to read the MIB and the SIB, so as to obtain the relevant information of the NR cell to which the NR frequency belongs. Then, the terminal device determines whether the NR cell supports the SA according to the related information of the NR cell. When the NR cell supports the SA, the terminal equipment can reselect or redirect to the NR cell and then register to an NR core network (5 GC).

If the terminal equipment judges that the NR cell does not support the SA, the judgment operation needs to be executed again aiming at the next obtained NR frequency point. Therefore, the judgment process executed for the NSA frequency point is an ineffective process for the idle terminal device supporting the SA, and the time length for the terminal device to perform cell reselection or cell redirection is prolonged.

The application provides an information processing method, in the information processing method, a first frequency point issued by a system message or a redirection message is a frequency point of a cell supporting SA, so that when idle terminal equipment supporting SA performs cell reselection based on the system message or performs cell redirection based on the redirection message, operations such as judgment and the like do not need to be executed because the issued frequency point may be NSA frequency point, and therefore the time required by cell reselection or redirection is prevented from being prolonged.

Referring to fig. 4, fig. 4 is a flowchart illustrating an information processing method 100 according to an embodiment of the present disclosure, where the information processing method is applicable to the communication system shown in fig. 1. At this time, the network device in fig. 1 is a first network device, and the first network device may be an LTE network device or an NR network device. The terminal device in fig. 1 is an idle terminal device accessing the first cell and supporting the SA. The information processing method is explained from the point of view of interaction between the first network device and the terminal device. The information processing method 100 includes the steps of:

s101, the first network equipment determines that the first frequency point is an independent networking frequency point or a mixed networking frequency point of independent networking and non-independent networking according to the switching information of the first frequency point.

Wherein, the switching information of the first frequency point comprises: the information that the terminal equipment accessed to the first cell is successfully switched from the first cell to the second cell and/or the information that the terminal equipment accessed to the second cell is successfully switched from the second cell to the first cell; the first network device is a network device to which the first cell belongs, the frequency point of the second cell is a first frequency point, and the second cell is an NR cell.

Optionally, the number of terminal devices accessing the first cell may be one or more, and the number of terminal devices accessing the second cell may be one or more. Correspondingly, the switching information of the first frequency point may include: the information of successful switching from the first cell to the second cell by one or more terminal devices accessing the first cell, and/or the information of successful switching from the second cell to the first cell by one or more terminal devices accessing the second cell.

Example 1: as shown in fig. 5a, terminal device 1 and terminal device 2 are both terminal devices accessing the first cell. In fig. 5a, the direction indicated by the arrow is taken as the direction of terminal device handover, and the handover information of the first frequency point may include: information that the terminal device 1 has succeeded in handover from the first cell to the second cell, and information that the terminal device 2 has succeeded in handover from the first cell to the second cell.

Example 2: as shown in fig. 5b, terminal device 1 and terminal device 2 are both terminal devices accessing the second cell. In fig. 5b, the direction indicated by the arrow is taken as the direction of terminal device handover, and the handover information of the first frequency point may include: information that the handover of terminal device 1 from the second cell to the first cell is successful, and information that the handover of terminal device 2 from the second cell to the first cell is successful.

Example 3: as shown in fig. 5c, terminal device 1 and terminal device 2 are terminal devices accessing a first cell, and terminal device 3 is a terminal device accessing a second cell. In fig. 5c, the direction indicated by the arrow is taken as the direction of terminal device handover, and the handover information of the first frequency point may include: information that the handover of terminal device 1 from the first cell to the second cell was successful, information that the handover of terminal device 2 from the first cell to the second cell was successful, and information that the handover of terminal device 3 from the second cell to the first cell was successful.

Optionally, the terminal device accessing the first cell and the terminal device accessing the second cell may be the same or different. When the terminal equipment accessing the first cell is the same as the terminal equipment accessing the second cell, it is indicated that the terminal equipment accesses the first cell and the second cell respectively at different times.

In one aspect of the information processing method, the switching information of the first frequency point is information that a terminal device accessing the first cell successfully switches from the first cell to the second cell, that is, information that the terminal device accessing the first cell successfully switches out of the first cell and switches to the second cell. In another case, the switching information of the first frequency point is information that the terminal equipment accessing the second cell is successfully switched from the second cell to the first cell, that is, the terminal equipment accessing the second cell is successfully switched from the second cell to the first cell; in another case, the handover information of the first frequency point includes: the information that the terminal equipment of the first cell is successfully switched from the first cell to the second cell, and the information that the terminal equipment accessed into the second cell is successfully switched from the second cell to the first cell.

The following explains information that the terminal device accessing the first cell is successfully switched from the first cell to the second cell, and information that the terminal device accessing the second cell is successfully switched from the second cell to the first cell:

in the embodiment 1.1, the information that the terminal equipment accessing the first cell is successfully switched from the first cell to the second cell comprises the receiving times of the first signaling; the receiving times of the first signaling are larger than or equal to a first threshold value. The first signaling is received by the first network device and used for indicating the terminal device accessing the first cell to be successfully switched from the first cell to the second cell. As can be seen, in this embodiment, the first network device may determine, according to the first signaling, that the terminal device accessing the first cell is successfully handed over from the first cell to the second cell, that is, the second cell supports access or residence of the terminal device, so that the frequency point (i.e., the first frequency point) of the second cell is an SA frequency point or a mixed networking frequency point of SA and NSA.

Optionally, the communication system shown in fig. 1 may further include a second network device, where the second network device may be an NR network device to which the second cell belongs. The first signaling may be obtained by the first network device from the second network device.

For example, the first network device and the second network device are NR base stations, and the first signaling may be a terminal CONTEXT RELEASE command (UE CONTEXT RELEASE) or a handover success command (handover success) that the first network device receives from the second network device through the Xn interface. Alternatively, the first signaling may be a terminal CONTEXT RELEASE COMMAND (UE CONTEXT RELEASE COMMAND) or a handover success COMMAND (handover success) that the first network device receives from an access and mobility management function (AMF) device in the NR core network. The NR core network is a core network to which both the first network device and the second network device access.

For another example, the first network device is an LTE base station, the second network device is an NR base station, and the first signaling may be a terminal CONTEXT RELEASE COMMAND (UE CONTEXT RELEASE COMMAND) received by the first network device from a Mobility Management Entity (MME) in the LTE core network. The LTE core network is a core network accessed by first network equipment, and an MME in the LTE core network sends a terminal context release command to the first network equipment after acquiring a signaling from the NR core network for indicating that terminal equipment accessed to a first cell is successfully switched from the first cell to a second cell. The NR core network is a core network to which the second network device accesses.

Optionally, the first signaling received by the first network device for multiple times may be signaling used for instructing the same terminal device to successfully switch to the second cell, or signaling used for instructing different terminal devices to successfully switch to the second cell. For example, the first signaling received by the first network device includes first signaling 1, first signaling 2, and first signaling 3. The first signaling 1 and the first signaling 2 are respectively used to indicate that the terminal device 1 accessing the first cell is successfully handed over from the first cell to the second cell, which indicates that the terminal device 1 is successfully handed over from the first cell to the second cell at different times. The first signaling 3 is used to indicate that the terminal device 2 accessing the first cell is successfully handed over from the first cell to the second cell, and the terminal device 2 and the terminal device 1 are different terminal devices.

Optionally, the second cell may be any NR cell in one or more neighboring cells configured in the first network device. Or, the second cell may also be any NR cell in one or more neighboring cells determined by the first network device through automatic neighboring cell discovery. Still alternatively, the second cell may also be any NR cell in one or more neighboring cells determined by the first network device based on the neighboring cell measurement information of the terminal device.

Optionally, the first threshold may be predefined or determined by the first network device according to network environment, channel condition, etc., and is not limited herein.

Optionally, before the first network device determines that the first frequency point is an SA frequency point or a mixed networking frequency point of SA and NSA according to the switching information of the first frequency point, the method may further include: the first network equipment counts the received first signaling to obtain the receiving times of the first signaling. Wherein the counting, by the first network device, the received first signaling may include: and the first network equipment adds 1 to the receiving times of the first signaling after receiving the first signaling once.

In embodiment 1.2, the information that the terminal device accessing the first cell successfully switches from the first cell to the second cell includes: the switching success rate of the terminal equipment accessed to the first cell from the first cell to the second cell; wherein the handover success rate is greater than or equal to the second threshold. In this embodiment, the first network device may determine that the first frequency point is an SA frequency point or a mixed networking frequency point of SA and NSA according to a handover success rate of a terminal device accessing the first cell to handover from the first cell to the second cell, which is beneficial to improving an identification accuracy rate of the first frequency point being an SA frequency point or the first frequency point being a mixed networking frequency point of SA and NSA.

Optionally, the handover success rate may be determined according to the number of times of sending the second signaling and the number of times of receiving the first signaling; the second signaling is a signaling sent by the first network device, and is used for requesting to switch the terminal device accessing the first cell from the first cell to the second cell.

For example, the first network device sends second signaling 1, second signaling 2, and second signaling 3. The second signaling 1 is used to request to switch the terminal device 1 accessing the first cell from the first cell to the second cell, the second signaling 2 is used to request to switch the terminal device 2 accessing the first cell from the first cell to the second cell, and the second signaling 3 is used to request to switch the terminal device 3 accessing the first cell from the first cell to the second cell. In addition, the first network device receives the first signaling 1 and the first signaling 2. The first signaling 1 is used to indicate that the terminal device 1 accessing the first cell is successfully handed over from the first cell to the second cell, and the first signaling 2 is used to indicate that the terminal device 3 accessing the first cell is successfully handed over from the first cell to the second cell. Then the handover success rate is 2/3, i.e. about 66.7%.

Optionally, the second signaling sent by the first network device multiple times may be used to request that the same terminal device is handed over from the first cell to the second cell, or may be used to request that different terminal devices are handed over from the first cell to the second cell. For example, the first network device sends second signaling 1, second signaling 2, and second signaling 3. The second signaling 1 and the second signaling 3 are respectively used for requesting to switch the terminal device 1 accessing the first cell from the first cell to the second cell, the second signaling 2 is used for requesting to switch the terminal device 2 accessing the first cell from the first cell to the second cell, and the terminal device 1 and the terminal device 2 are different terminal devices.

Optionally, the second threshold may be predefined or determined by the first network device according to network environment, channel condition, etc., and is not limited herein.

Optionally, before the first network device determines that the first frequency point is an SA frequency point or a mixed networking frequency point of SA and NSA according to the switching information of the first frequency point, the method may further include: and the first network equipment counts the sent second signaling to obtain the sending times of the second signaling. The counting, by the first network device, the sent second signaling may include: and the first network equipment sends the second signaling once, and adds 1 to the sending times of the second signaling.

In embodiment 1.3, the information that the terminal device accessing the second cell successfully switches from the second cell to the first cell includes: and the number of times of successful switching from the second cell to the first cell by the terminal equipment accessing the second cell is greater than or equal to a third threshold value. In this embodiment, the first network device may determine, according to the number of times that the terminal device accessing the second cell is successfully switched from the second cell to the first cell, that the second cell supports the terminal device to access or camp on, and may further determine that the frequency point (i.e., the first frequency point) of the second cell is an SA frequency point or a mixed networking frequency point of SA and NSA.

Optionally, the number of times that the terminal device accessing the second cell is successfully switched from the second cell to the first cell may be determined by the first network device according to history information of each terminal device accessing the first cell. The history information of the terminal device accessing the first cell may include: information of one or more NR cells to which the terminal device has access or camped. In this way, the first network device may count the number of terminal devices that are accessed to or camped on the NR cell that is the second cell according to the information of the one or more NR cells accessed to or camped on by each terminal device, and use the number of terminal devices that are accessed to or camped on the NR cell that is the second cell as the number of times for which the terminal device that is accessed to the second cell is successfully handed over from the second cell to the first cell.

For example, each terminal device accessing the first cell includes terminal device 1 and terminal device 2. Wherein, the history information of the terminal device 1 includes: information of NR cell 1 and information of NR cell 2, history information of terminal device 2 includes: information of NR cell 2 and information of NR cell 3. Then, the number of times that the terminal device accessing the NR cell 1 successfully switches from the NR cell 1 to the first cell is 1, the number of times that the terminal device accessing the NR cell 2 successfully switches from the NR cell 2 to the first cell is 2, and the number of times that the terminal device accessing the NR cell 3 successfully switches from the NR cell 3 to the first cell is 1.

Optionally, the third threshold may be predefined or determined by the first network device according to network environment, channel condition, and the like, and is not limited herein.

In an optional implementation manner, the switching information of the first frequency point is determined by the first network device within a preset time period. The preset time period may be a longer period of time, for example, the preset time period may be 10 minutes, 1 hour, half a day, or the like. In this embodiment, the first network device may count the switching information of the first frequency point within a preset time period, so that the counted switching information of the first frequency point is better in real-time performance, and it is beneficial to improve the identification accuracy that the first frequency point is an SA frequency point or a mixed networking frequency point where the first frequency point is an SA and NSA. Optionally, the preset time period may be predefined or determined by the first network device according to network environment, channel condition, and the like, which is not limited herein.

In an alternative embodiment, the method further comprises: the first network equipment starts a timer and counts the switching information of the first frequency point; and when the timer is overtime, the first network equipment executes the step of determining that the first frequency point is the SA frequency point or the mixed networking frequency point of the SA and the NSA according to the switching information of the first frequency point. Therefore, the first network device counts the switching information of the first frequency point during the timing of the timer, so that the obtained switching information of the first frequency point can better reflect the actual situation of the first frequency point, and the identification accuracy of the first frequency point being an SA frequency point or a mixed networking frequency point of SA and NSA can be improved. And after the timer is overtime, the first network equipment updates the system message or the redirection message according to the switching information of the first frequency point. In addition, after the timer is overtime, timing can be restarted, and then the first network device can perform the step of counting the switching information of the first frequency point again.

S102, the first network equipment sends a system message or a redirection message carrying the identification of the first frequency point in the first cell. Correspondingly, the terminal equipment receives the system message or the redirection message carrying the identifier of the first frequency point.

Optionally, the system message may include: identification of the first frequency point (such as the frequency point number of the first frequency point), a multiband (band) information list, a synchronization signal and Physical Broadcast Channel (PBCH) block (SSB) subcarrier interval, an SSB period, an SSB offset, an SSB measurement duration, a high priority reselection threshold, a low priority reselection threshold, a reselection priority, a reselection sub-priority, a lowest reception level, a maximum allowed transmission power, and other information. The redirection message may include: the identifier of the first frequency point (such as the frequency point number of the first frequency point), the SSB subcarrier interval, the SSB period, the SSB offset, the SSB measurement duration, and other information.

In addition, when the first network device is an LTE network device, the system message may be an SIB24, and the redirection message may be a Radio Resource Control (RRC) Connection Release message (RRC Connection Release message). When the first network device is an NR network device, the system message may be SIB3 and/or SIB4, and the redirection message may be an RRC Release message (RRC Release message).

And S103, the terminal equipment reselects or redirects to the second cell according to the identifier of the first frequency point.

The terminal device may reselect the second cell according to the identifier of the first frequency point in the system message, or the terminal device may redirect to the second cell according to the identifier of the first frequency point in the redirection message.

In an alternative embodiment, with reference to fig. 6a, before the first network device performs step S101, the method may further include: the first network equipment determines switching information of a first frequency point; and judging whether the switching information of the first frequency point meets a preset condition. When the switching information of the first frequency point meets the preset condition, the first network equipment determines that the first frequency point is an SA frequency point or the first frequency point is a mixed networking frequency point of SA and NSA, and then issues the first frequency point in a system message or a redirection message, namely the first network equipment executes the steps S101 to S102; then, the terminal device may reselect or redirect to the second cell according to the identifier of the first frequency point. When the switching information of the first frequency point does not meet the preset condition, the first network equipment does not issue the first frequency point in the system message or the redirection message if the first frequency point is considered to be the NSA frequency point. The implementation mode can improve the automation and the intelligence of the first network equipment for determining whether to issue the first frequency point in the system message or the redirection message.

In this embodiment, in one case, the switching information of the first frequency point is the number of times of receiving the first signaling, and the preset condition may be that the number of times of receiving the first signaling is greater than or equal to a first threshold. Then, when the number of times of receiving the first signaling is greater than or equal to a first threshold, the first network device determines that the first frequency point is an SA frequency point, or the first frequency point is a mixed networking frequency point of SA and NSA, and issues the first frequency point in a system message or a redirection message; and when the receiving times of the first signaling is smaller than a first threshold value, not issuing the first frequency point in the system message or the redirection message.

In another case, the switching information of the first frequency point is a switching success rate of the terminal device accessing the first cell for switching from the first cell to the second cell, and the preset condition may be that the switching success rate is greater than or equal to a second threshold. Then, when the switching success rate of the first network device is greater than or equal to a second threshold, determining that the first frequency point is an SA frequency point, or the first frequency point is a mixed networking frequency point of SA and NSA, and issuing the first frequency point in a system message or a redirection message; and when the switching success rate is smaller than a second threshold value, the first frequency point is not issued in the system message or the redirection message.

In another case, the switching information of the first frequency point is the number of times that the terminal device accessing the second cell successfully switches from the second cell to the first cell, and the preset condition may be that the number of times that the terminal device accessing the second cell successfully switches from the second cell to the first cell is greater than or equal to a third threshold. Then, when the number of times of successful switching is greater than or equal to a third threshold value, the first network device determines that the first frequency point is an SA frequency point, or the first frequency point is a mixed networking frequency point of SA and NSA, and issues the first frequency point in a system message or a redirection message; and when the successful times of the switching are smaller than a third threshold value, the first frequency point is not issued in the system message or the redirection message.

In another case, the handover information of the first frequency point includes: the preset condition may be that the number of times of receiving the first signaling is greater than or equal to a first threshold, and the number of times of successfully switching the terminal device accessing the second cell from the second cell to the first cell is greater than or equal to a third threshold. Then, when the number of times of receiving the first signaling is greater than or equal to a first threshold and the number of times of successful switching is greater than or equal to a third threshold, the first network device determines that the first frequency point is an SA frequency point or a mixed networking frequency point of SA and NSA, and issues the first frequency point in a system message or a redirection message; otherwise, the first frequency point is not issued in the system message or the redirection message.

In another case, the handover information of the first frequency point includes: the preset conditions include a switching success rate of the terminal equipment accessed to the first cell from the first cell to the second cell and the switching success frequency of the terminal equipment accessed to the second cell from the second cell to the first cell, where the switching success rate is greater than or equal to a second threshold, and the switching success frequency of the terminal equipment accessed to the second cell from the second cell to the first cell is greater than or equal to a third threshold. Then, when the switching success rate of the first network device is greater than or equal to a second threshold and the switching success frequency is greater than or equal to a third threshold, determining that the first frequency point is an SA frequency point or a mixed networking frequency point of the SA and the NSA, and issuing the first frequency point in a system message or a redirection message; otherwise, the first frequency point is not issued in the system message or the redirection message.

In another optional implementation, with reference to fig. 6b, when the switching information of the first frequency point meets a preset condition, the first network device directly issues the first frequency point in a system message or a redirection message; when the switching information of the first frequency point does not meet the preset condition, the first network equipment does not issue the first frequency point in the system message or the redirection message.

In summary, in the information processing method, the first network device determines that the first frequency point is an SA frequency point or a first frequency point is a mixed networking frequency point of SA and NSA according to the switching information of the first frequency point; and sending a system message or a redirection message carrying the identifier of the first frequency point in the first cell. Wherein, the switching information of the first frequency point comprises: the information that the terminal equipment accessed to the first cell is successfully switched from the first cell to the second cell and/or the information that the terminal equipment accessed to the second cell is successfully switched from the second cell to the first cell; the first network device is a network device to which the first cell belongs, the frequency point of the second cell is a first frequency point and the second cell is an NR cell. And the terminal equipment can reselect or redirect to the second cell according to the identifier of the first frequency point.

Therefore, when the idle terminal equipment supporting the SA performs cell reselection based on the system message or performs cell redirection based on the redirection message, operations such as judgment and the like do not need to be performed because the issued frequency point may be an NSA frequency point, thereby avoiding prolonging the time required by cell reselection or redirection. In addition, in the method, the first network device determines that the first frequency point is an SA frequency point or a mixed networking frequency point of SA and NSA, instead of an NSA frequency point, according to the switching information of the first frequency point, and compared with a mode of manually marking whether the frequency point is an NSA frequency point or not to filter the NSA frequency point, workload and complexity of manual operation and maintenance can be avoided being increased. In addition, the method can avoid the possible misjudgment risk on configuration identification due to the mode of manually marking and filtering the NSA frequency points.

Based on the information processing method 100 shown in fig. 4, an exemplary information processing scheme is provided below. Referring to fig. 7, fig. 7 is a flowchart illustrating an exemplary information processing scheme according to an embodiment of the present application. The information processing scheme includes the steps of:

s201, the first network equipment starts a timer.

S202, the first network equipment counts the switching information of the first frequency point. The switching information of the first frequency point comprises: the information that the terminal equipment accessed to the first cell is successfully switched from the first cell to the second cell and/or the information that the terminal equipment accessed to the second cell is successfully switched from the second cell to the first cell; the first network device is a network device to which the first cell belongs, the frequency point of the second cell is a first frequency point, and the second cell is an NR cell.

S203, the first network device determines whether the timer is overtime. When the timer does not time out, the first network device continues to execute step S202; when the timer times out, steps S204 to S206 are performed.

S204, the first network equipment judges whether the switching information of the first frequency point meets a preset condition. When the switching information of the first frequency point does not meet the preset condition, the first network equipment does not issue the first frequency point in the system message or the redirection message. When the switching information of the first frequency point meets the preset condition, the first network device executes steps S205 to 207.

S205, the first network equipment determines that the first frequency point is an SA frequency point, or the first frequency point is a mixed networking frequency point of SA and NSA.

S206, the first network equipment sends a system message or a redirection message carrying the identification of the first frequency point in the first cell. Correspondingly, the terminal equipment receives the system message or the redirection message carrying the identifier of the first frequency point.

And S207, the terminal equipment reselects or redirects to the second cell according to the identifier of the first frequency point. In summary, in the information processing scheme, the first network device counts the switching information of the first frequency point, determines that the first frequency point is an SA frequency point or a mixed networking frequency point of SA and NSA when the switching information of the first frequency point meets a preset condition, and issues the first frequency point in the system message or the redirection message. And when the first frequency point does not meet the preset condition, the first network equipment does not issue the first frequency point in the system message or the redirection message. Therefore, when the idle terminal equipment supporting the SA performs cell reselection based on the system message or performs cell redirection based on the redirection message, the issued frequency point may be an NSA frequency point and needs not to perform operations such as judgment and the like, thereby avoiding prolonging the time required by cell reselection or redirection. In addition, compared with the mode of manually marking whether the frequency point is the NSA frequency point or not to filter the NSA frequency point, the information processing scheme can avoid increasing the workload and complexity of manual operation and maintenance and also can avoid the misjudgment risk possibly existing in configuration identification due to the mode of manually marking and filtering the NSA frequency point.
