[0027] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0028] First combine Figure 1 Some embodiments of the information processing method of the present disclosure are described.

[0029] Figure 1 FIG. 1 is a flow chart showing an information processing method according to some embodiments of the present disclosure. Figure 1 As shown, the method includes steps S101 to S102.

[0030] In step S101, the first base station receives network slice fallback information sent by the terminal.

[0031] The network slice fallback information may indicate the fallback status of the terminal between different network slices. The terminal may fall back from one slice to another, for example, the terminal moves to an area with poor coverage of the original slice, or the original slice served by the terminal has insufficient resources. The network slice fallback information includes at least one of the following: the network slice identifier of the slice where the terminal is located before the slice falls back, the slice group identifier corresponding to the slice where the terminal is located before the slice falls back, the service cell identifier of the terminal before the slice falls back, the service frequency band of the terminal before the slice falls back, the TAC of the area where the terminal is located before the slice falls back, the RNA identifier of the area where the terminal is located before the slice falls back, the network slice identifier of the slice where the terminal is located after the slice falls back, the slice group identifier corresponding to the slice where the terminal is located after the slice falls back, the service cell identifier of the terminal after the slice falls back, the service frequency band of the terminal after the slice falls back, the TAC of the area where the terminal is located after the slice falls back, the RNA identifier of the area where the terminal is located after the slice falls back, the number of consecutive slice falls back, the number of slice falls back within a preset time, the time the terminal stays in the network slice where the terminal is located before the slice falls back, the time the terminal stays in the network slice to which the slice falls back, the fallback reason, the time information when the slice falls back occurs, the location information of the terminal when the slice falls back, the network slice identifier expected by the terminal, the slice group identifier expected by the terminal, and the cell reselection priority corresponding to the slice.

[0032] In step S102, the first base station sends the network slice fallback information to the network self-optimization function device.

[0033] The network self-optimization function device is located in the first base station or the second base station or the operation and maintenance management device or the core network device. The network self-optimization function device can obtain the information of the terminal falling back between different slices, evaluate whether the resource and parameter settings of the slices are reasonable, and then optimize the network for the slices, such as capacity expansion (increasing resource allocation) or load balancing (releasing some terminals served by the slices).

[0034] In some embodiments, the information processing method further includes steps S103 to S105.

[0035] In step S103, the network self-optimization function device determines whether it is necessary to adjust the configuration of the network slice based on the network slice fallback information.

[0036] Among them, the configuration corresponding to the network slice includes one or more of resource configuration and fallback parameter configuration.

[0037] In step S104, the network self-optimization function determines that the configuration of the network slice needs to be adjusted, and sends the adjusted network slice configuration information to the first base station.

[0038] In step S105, the first base station sends the difference information between the adjusted network slice configuration information and the network slice configuration information before adjustment to the second base station.

[0039] In some embodiments, the information processing method further includes step S100.

[0040] In step S100, the first base station sends a terminal information request message to the terminal, where the terminal information request message carries a slice fallback information request.

[0041] In some embodiments, step S102 also includes: the first base station sends part or all of the information in the network slice fallback information to the second base station.

[0042] Those skilled in the art can understand that the first base station and the second base station in the above embodiment can be base stations with separate control plane units and forwarding plane units, or can be non-separated base stations. Network slices can include radio access network slices, core network slices, and bearer network slices. The network slice identifier can be S-NSSAI (Single Network Slice Selection Assistance Information). Slice fallback can also be called slice remapping. The fallback reason can be overload or the network does not support a specific slice or the network does not allow a specific slice or other. The core network device can be AMF (Access and Mobility Management Function), MME, or orchestration center. The slice group identifier is an identifier for identifying a group of slices. A slice group identifier can correspond to a group of network slice identifiers. Slice fallback includes that the network slice expected by the terminal is different from the network slice selected by the network for the terminal, the network slice selected by the network for the terminal changes, the network slice selected by the terminal changes, and the network slice selected by the network and the terminal changes.

[0043] The above-mentioned embodiments enable the network to obtain network slice fallback information, provide input parameters for the network self-optimization function device, and assist the network self-optimization function device to determine whether the resource configuration and fallback parameter settings of each network slice are reasonable, and whether it is necessary to adjust a single or multiple network slices, so as to achieve the effect of self-optimization of the mobility of a specific network slice without manual intervention.

[0044] Some specific application examples of the information processing method disclosed herein are described below.

[0045] (First Application Example)

[0046] In the first application example, the terminal reports the network slice fallback information, and the first base station sends it to the network self-optimization function device. After the network self-optimization function analyzes it, it sends the network configuration that needs to be adjusted to the first base station. The specific implementation process is as follows:

[0047] (1) The base station sends a terminal information request message to the terminal, carrying a slice fallback information request;

[0048] (2) The terminal sends information about the terminal falling back between different network slices to the base station, including one or more of the following: the network slice identifier / corresponding serving cell identifier / frequency band where the terminal was before falling back, the network slice identifier / corresponding serving cell identifier / frequency band where the terminal was after falling back, the number of consecutive fallbacks, the number of fallbacks within a preset time, the time the terminal stayed in the network slice where it was before falling back, the time the terminal stayed in the network slice to which it fell back, and the fallback reason;

[0049] (3) The base station receives the network slice fallback information and then sends it to the network self-optimization function device;

[0050] (4) The network self-optimization function device determines whether the configuration corresponding to the network slice needs to be adjusted based on the collected network slice fallback information, including one or more of the following: resource configuration, fallback parameter configuration

[0051] (5) If the network self-optimization function device determines that the configuration corresponding to a specific network slice needs to be adjusted, the network self-optimization function device sends the adjusted configuration information corresponding to the network slice to the base station.

[0052] (Second application example)

[0053] In the second application example, the terminal reports the network slice fallback information, and the base station sends the information to the neighboring base station. If the network slice configuration (resource configuration, fallback parameters) needs to be adjusted, the base station sends the difference information of the network slice configuration before and after the adjustment to the neighboring base station. The specific implementation process is as follows:

[0054] (1) The base station sends a terminal information request message to the terminal, carrying a slice fallback information request;

[0055] (2) The terminal sends information about the terminal falling back between different network slices to the base station, including one or more of the following: the network slice identifier / corresponding serving cell identifier / frequency band where the terminal was before falling back, the network slice identifier / corresponding serving cell identifier / frequency band where the terminal was after falling back, the number of consecutive fallbacks, the number of fallbacks within a preset time, the time the terminal stayed in the network slice where it was before falling back, the time the terminal stayed in the network slice to which it fell back, and the fallback reason;

[0056] (3) The base station receives the network slice fallback information and then sends it to the network self-optimization function device;

[0057] (4) The base station sends part or all of the network slice fallback information to the neighboring base station;

[0058] (5) The network self-optimization function device determines whether the configuration corresponding to the network slice needs to be adjusted based on the collected network slice fallback information, including one or more of the following: resource configuration and fallback parameter configuration;

[0059] (6) If the network self-optimization function device determines that the configuration corresponding to a specific network slice needs to be adjusted, the network self-optimization function device sends the adjusted configuration information corresponding to the network slice to the base station.

[0060] (7) If the network slice configuration (resource configuration, fallback parameters) of the base station is adjusted, the base station will send the difference information of the network slice configuration before and after the adjustment to the neighboring base stations.

[0061] (Third Application Example)

[0062] In the third application example, the terminal reports the network slice fallback information, and the base station sends the information to the neighboring base station. If the network slice configuration (resource configuration, fallback parameters) of the neighboring base station is judged to need to be adjusted based on the information and other information collected by the neighboring base station, the neighboring base station sends the difference information of the network slice configuration before and after the adjustment to the base station. The specific implementation process is as follows:

[0063] (1) The base station sends a terminal information request message to the terminal, carrying a slice fallback information request;

[0064] (2) The terminal sends information about the terminal falling back between different network slices to the base station, including one or more of the following: the network slice identifier / corresponding serving cell identifier / frequency band where the terminal was before falling back, the network slice identifier / corresponding serving cell identifier / frequency band where the terminal was after falling back, the number of consecutive fallbacks, the number of fallbacks within a preset time, the time the terminal stayed in the network slice where it was before falling back, the time the terminal stayed in the network slice to which it fell back, and the fallback reason;

[0065] (3) The base station sends part or all of the network slice fallback information to the neighboring base station;

[0066] (4) If the network self-optimization function associated with the neighboring base station determines that the network slice configuration information (resource configuration, fallback parameters) of the neighboring base station needs to be adjusted based on the received network slice fallback information and other information collected by the neighboring base station, the neighboring base station sends the difference information of the network slice configuration before and after the adjustment to the base station.
