For example, assuming that there are service 1 and service 2, the functional module of the RAN slice corresponding to service 1 may include an encryption/decryption functional module, and the TTI is 1ms, and the functional module of the RAN slice corresponding to service 2 may not include an encryption/decryption functional module, and the TTI is 0.5 ms.

Fig. 1 is a schematic diagram of a logic architecture to which the technical solution provided by the embodiment of the present invention is applied. The logical architecture diagram shown in fig. 1 includes a RAN slice manager 11, an infrastructure controller 12, and a RAN slice collection 13. The RAN slice manager 11 is a decision unit for managing RAN slices, and managing RAN slices may include, but is not limited to, at least one of the following: create, delete, reconfigure, or query RAN slices, etc. Infrastructure controller 12 is an execution unit that manages RAN slices. RAN slice set 13 is a set of RAN slices that have been created and not deleted. RAN slice set 13 may include one or more RAN slices.

Optionally, the logic architecture diagram shown in fig. 1 may further include at least one of the following: a physical resource database 14, a RAN slice database 15, and a physical layer function module 16. The physical resource database 14 is used for storing the use condition of the physical resource; for example, the physical resource database 14 may be used to store information of free physical resources. The information of the physical resources may include, but is not limited to, information of resources such as computing resources, storage resources, and wireless spectrum resources. The wireless spectrum resources may include, but are not limited to, a center frequency, a wireless spectrum bandwidth, and a parameter configuration of the wireless spectrum resources. The parameter configuration of the wireless spectrum resources may include, but is not limited to, at least one of the following information: TTI, subcarrier spacing, RBG, etc. The RAN slice database 15 is used to store information of RAN slices; for example, the RAN slice database 15 may be used to store information of RAN slices that have been created; optionally, information of the non-created RAN slice may also be stored, which may be referred to below.

The physical resource database 14 may be a public database or may be a private database of the RAN slice manager 11 or a private database of the infrastructure controller 12. The physical resource database 14 is a public database, and can be understood as: the database is shared by a plurality of RAN slice managers 11, or a plurality of infrastructure controllers 12, or one RAN slice manager 11 and one or more infrastructure controllers 12, or one or more RAN slice managers 11 and one infrastructure controller 12, or a plurality of RAN slice managers 11 and a plurality of infrastructure controllers 12. The private database of the RAN slice manager 11 can be understood as: only the RAN slice manager 11 can use the database. The private database of the infrastructure controller 12 can be understood as: only the infrastructure controller 12 can use the database.

The RAN slice database 15 may be a public database or may be a private database of the RAN slice manager 11. Among these, the RAN slice database 15 is used as a common database, and can be understood as: multiple RAN slice managers 11 may share the database. The RAN slice database 15 serves as a private database of the RAN slice manager 11, and can be understood as: only the RAN slice database 11 can use the database.

In addition, the physical resource database 14 and the RAN slice database 15 may exist at the same time, or may exist only one, or may not exist at all. When not present, the corresponding RAN slice or physical resource information may be stored inside the RAN slice manager 11 or the infrastructure controller 12, and the RAN slice manager 11 or the infrastructure controller 12 may use and update the RAN slice or physical resource information stored therein.

The logical architecture shown in fig. 1 may be applied in a variety of physical architectures. This is illustrated below by means of several examples.

RAN slices are briefly introduced below:

1. RAN slice and configuration information of RAN slice

The configuration information of different RAN slices is different and the identity of a RAN slice may be used to label one RAN slice. The same RAN slice may have one or more kinds of configuration information, but one RAN slice has only one kind of configuration information at the same time. It should be noted that the reason for having multiple configuration information for one RAN slice may include, but is not limited to, reconfiguring one RAN slice; that is, before and after reconfiguration of one RAN slice, configuration information of the RAN slice is different. For example, the correspondence between the RAN slice and the configuration information is shown in table 1:

TABLE 1

The configuration information of RAN slice 2 in table 1 can be understood as: at time t1, the configuration information of RAN slice 2 is configuration information 21; at time t2, the configuration information of RAN slice 2 is configuration information 22. The configuration information of RAN slice 1 is similarly explained, and is not described in detail here.

2. Configuration information for RAN slices

The configuration information of the RAN slice may include: functional module information, physical resource information, and the like. The different configuration information may include configuration information of different RAN slices and different configuration information of the same RAN slice. Specifically, but not limited to, at least one of information of the differentiated functional module and the differentiated radio spectrum resource may be included. The information of the differentiated functional module may include, but is not limited to, at least one of the following information: the composition information of the differentiated functional module, if yes, whether the functional module has an encryption and decryption functional module; the function configuration of the differentiated function module, if yes, the encryption and decryption functions are started; and configuring parameters of the differentiated functional modules, such as which encryption and decryption algorithm is used by the encryption and decryption function. The differentiated physical resource information may include, but is not limited to, at least one of the following: differentiated computing resources, differentiated storage resources, differentiated radio spectrum resources, and the like.

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship. The terms "first" and "second" are used herein for the purpose of distinguishing different objects more clearly, and are not limited to any other. "plurality" herein means two or more. As used herein, a "device" may be understood as an access network device that may include, but is not limited to, the physical architecture shown in any of the above-described figures 2-7.

It should be noted that, all the following description is given by taking the application of the technical solution provided by the embodiment of the present invention to the logical architecture diagram shown in fig. 1 as an example, and a person skilled in the art should be able to map the technical solution provided by the embodiment of the present invention to a corresponding physical architecture according to the content described below, which is not described below.

As shown in fig. 8a, an interaction diagram of a method for creating a RAN slice according to an embodiment of the present invention is provided. The method shown in FIG. 8a may include the following steps S801a-S803 a:

s801 a: the RAN slice manager obtains initial configuration information of the RAN slice.

Optionally, S801a may include: the RAN slice manager obtains initial configuration information of the RAN slice through the RAN slice database. The initial configuration information for different RAN slices may be the same or different.

Optionally, the initial configuration information of the RAN slice may include information of a functional module used by the RAN slice. Further optionally, at least one of the following information may be included: a functional configuration of a functional module used by the RAN slice, a parameter configuration of a functional module used by the RAN slice, information of computational resources used by the RAN slice, information of storage resources used by the RAN slice, and information of radio spectrum resources used by the RAN slice. The parameter configuration of the functional module comprises any one or more parameter configurations of any one or more functional modules in the functional module. The wireless spectrum resources include, but are not limited to, at least one of the following information: the center frequency of the wireless spectrum resource, the bandwidth of the wireless spectrum resource and the parameter configuration of the wireless spectrum resource. Wherein the parameter configuration of the radio spectrum resource comprises at least one of TTI, subcarrier spacing and RBG.

S802 a: the RAN slice manager sends a create indication message to the infrastructure controller, which receives the create indication message. Wherein the creation indication message may include initial configuration information, the creation indication message for instructing the infrastructure controller to create the RAN slice according to the initial configuration information.

Specifically, the initial configuration information included in the creation instruction message may be part or all of the initial configuration information acquired in S801 a.

S803 a: the infrastructure controller creates the RAN slice according to the initial configuration information in the create indication message.

Create a RAN slice, which can be understood as: and distributing physical resources for the RAN slice and starting a functional module according to the configuration information. These functional modules are run using the allocated physical resources.

In particular implementations, the RAN slice may be created by any of the following:

mode 1: all configuration information required for the infrastructure controller to create the RAN slice may be included in the creation indication message, in which case the infrastructure controller creates the RAN slice according to the all configuration information. Wherein the entire configuration information may be the initial configuration information. This approach can be understood as: the required RAN slice is created directly. Specifically, the following example 1 or example 2 may be referred to.

Mode 2: part of configuration information required by the infrastructure controller to create the RAN slice may be included in the creation indication message, and in this case, the infrastructure controller may create the RAN slice according to the part of configuration information and the default configuration information. The part of the configuration information may be a part of the initial configuration information. The default configuration information herein may include configuration information other than the portion of configuration information required by the infrastructure controller to create the RAN slice. This possible design can be understood as: a semi-generic RAN slice is created. Subsequently, the current configuration information of the semi-generic RAN slice can be reconfigured, so as to provide differentiated performance requirements for different services. Specifically, the following example 3 or example 4 may be referred to.

The embodiment of the invention provides a method for creating RAN slices, which is characterized in that the created RAN slices are different by setting initial configuration information of different RAN slices, so that different services can be mapped onto different RAN slices according to the performance requirements of the different services during specific implementation, and the differentiated performance requirements of the different services are met.

As shown in fig. 8b, an interaction diagram of a method for creating a RAN slice according to an embodiment of the present invention is provided. The method shown in FIG. 8b may include the following steps S801b-S802 b:

s801 b: the RAN slice manager sends a create indication message to the infrastructure controller, which receives the create indication message.

S802 b: the infrastructure controller creates the RAN slice according to the default configuration information.

In this embodiment, the creation indication message may not contain any configuration information required to create the RAN slice, in which case the infrastructure controller may create the RAN slice according to default configuration information. The default configuration information here may include all configuration information required by the infrastructure controller to create the RAN slice. This alternative design can be understood as: a generic RAN slice is created. Subsequently, the current configuration information of the general RAN slice can be reconfigured, so as to provide differentiated performance requirements for different services. Specifically, the following examples 3 to 6 can be referred to.

Example 1

Fig. 9 is an interaction diagram of a method for creating a RAN slice according to an embodiment of the present invention. The method shown in fig. 9 may include the following steps S901 to S915:

s901: receiving a service creation request message by the RAN slice manager; wherein the create service request message includes information of the service.

Specifically, the method comprises the following steps: and the RAN slice manager receives a service creation request message sent by network side equipment or terminal side equipment. The network side device is also called a northbound device, and the terminal side device is also called a southbound device. The network side device may include, but is not limited to, any of the following: a service provider server, a network operator server, a core network element, etc. By way of example, the service provider server may include, but is not limited to, any of the following: hundredth server, Tencent server, etc. The network operator server may include, but is not limited to, any of the following: mobile server, unicom server, etc. The core network elements may include, but are not limited to, any of the following: home Subscriber Server (HSS), Mobility Management Entity (MME), Gateway (GW), Policy and Charging Rules Function (PCRF), and other network elements that may appear in the future. The terminal side devices may include, but are not limited to, any of the following: mobile phones, computers, Virtual Reality (VR) helmets, internet of things devices, cameras, and the like.

If the services are differentiated according to the service types, the information of the services may include: ID of the service

(identity) or quality of service (QoS) requirements of the service. The QoS requirement may include, but is not limited to, at least one of the following information: time delay, throughput, packet loss rate, etc. If the services are differentiated according to the service types and the operators/service providers, the information of the services may include: the ID of the service and the ID of the operator/service provider.

S902: and the RAN slice manager judges whether the RAN slice corresponding to the service needs to be created or not according to the service information.

If not, the process is ended. If yes, go to S903.

In a specific implementation, if the determination result in S902 is "no", which indicates that the RAN slice has been created, the RAN slice manager maps the service to the RAN slice corresponding to the service, and subsequently, the RAN slice is used to provide a service for the service.

S902 may include, but is not limited to, the following two implementations:

the first method is as follows: the RAN slice manager determines whether a RAN slice corresponding to the service has been created by accessing the RAN slice database. If so, determining that the RAN slice does not need to be created, and if not, determining that the RAN slice needs to be created.

The second method comprises the following steps: the RAN slice manager accesses the RAN slice database to determine whether the originator (e.g., operator/service provider) that created the RAN slice has the right to create the RAN slice corresponding to the service. And if the RAN slice corresponding to the service is not created, determining that the RAN slice needs to be created, otherwise, not creating the RAN slice. It is noted that, it may also be determined whether the RAN slice corresponding to the service is already created, and if not, then it is determined whether an initiator that creates the RAN slice has an authority to create the RAN slice corresponding to the service, and if so, it is determined that the RAN slice needs to be created, otherwise, the RAN slice does not need to be created.

The following describes an exemplary correspondence between a service and a RAN slice according to different service differentiation methods:

if different services are distinguished according to the service types, the following steps are carried out: the RAN slices corresponding to different types of services may be the same or different, and the RAN slices corresponding to the same type of services are the same. An example is shown in table 2:

TABLE 2

Information of a service	Identification of RAN slices
		ID of video service	RAN slice	1
ID of voice service	RAN slice				1
		ID of short message service	RAN slice 2
ID of game service	RAN slice 3

If different services are distinguished according to the service types and operators/service providers, then: RAN slices corresponding to services provided by different operators/service providers of the same type may be the same or different; the RAN slices corresponding to services provided by the same operator/service provider of the same type are the same. The RAN slices corresponding to services provided by different types of different operators/providers may be the same or different, and the services provided by the same operator/provider of different types may be the same or different. An example is shown in table 3:

TABLE 3

The RAN slice database may store therein an identification of a RAN slice that has been created, and optionally, an identification of a RAN slice that has not been created. These two cases are exemplified below:

case 1: the RAN slice database stores the identities of the RAN slices that have been created and the identities of the RAN slices that have not been created. In this case, the RAN slice database may store a correspondence between: information of a service, an ID of a RAN slice, slice initial configuration information of a RAN, information whether a RAN slice has been created.

If different services are differentiated according to service types, a RAN slice database may be as shown in table 4:

TABLE 4

If different services are differentiated according to service type and operator/service provider, a RAN slice database may be as shown in table 5:

TABLE 5

Where "1" in table 4 and table 5 indicates that a RAN slice has been created, and "0" indicates that a RAN slice has not been created. In a specific implementation, the information indicating whether the RAN slice has been created may also be represented in other manners, which is not limited in this embodiment of the present invention. The initial configuration information 1 and 2 in table 4 may be the same or different. Any two pieces of initial configuration information in table 5 may be the same or different.

Case 2: the RAN slice database stores therein the identities of RAN slices that have been created and does not store the identities of RAN slices that have not been created. This situation applies generally to differentiating different services by service type and operator/service provider. In this case, the RAN slice database may store a correspondence between: information of the service (including the ID of the service and the identity of the operator/facilitator), the ID of the RAN slice, the initial configuration confidence of the RAN slice. Two examples of this are listed below:

example 1: the ID of the operator/facilitator to which the RAN slice corresponds is not saved until the RAN slice is not created. In this example, if no RAN slice has been created in the system, a RAN slice database may be as shown in table 6:

TABLE 6

Based on table 6, if a partial RAN slice has been created in the system, a RAN slice database may be as shown in table 7:

TABLE 7

Example 2: before the RAN slice is not created, the ID of the operator/service provider corresponding to the RAN slice is saved. In this example, if no RAN slice has been created in the system, a RAN slice database may be as shown in table 8:

TABLE 8

It should be noted that in a scenario where an operator/service provider needs to pay for a RAN slice to have a right to use the RAN slice, optionally, the RAN slice database may store an ID of the operator/service provider that is paid for, and not store an ID of an operator/service provider that is not paid for. Wherein, the operator/service provider who pays refers to the operator/service provider who purchases the usage right of the RAN slice; an operator/facilitator who does not pay a fee refers to an operator/facilitator who does not purchase usage rights for the RAN slice. For example, the ID of each operator/service provider in table 8 is the ID of the operator/service provider who purchased the usage right of the corresponding RAN slice, such as Tencent and Ali who purchased the usage right of the RAN slice corresponding to the video service.

Based on table 8, if a partial RAN slice has been created in the system, a RAN slice database may be as shown in table 9:

TABLE 9

It should be noted that, in a scenario where the operator/service provider needs to pay for the RAN slice to have the right to use the RAN slice, S902 may be implemented in the above-mentioned manner two specifically.

S903: the RAN slice manager obtains initial configuration information of the RAN slice by accessing a RAN slice database.

Among them, S901 to S903 may be regarded as a specific implementation of S801a described above.

S904: the RAN slice manager decides whether the RAN slice can be created according to the initial configuration information.

If yes, executing S905; if not, the process is ended.

Specifically, the RAN slice manager accesses the physical resource database to obtain the usage of the physical resources. If the use condition of the physical resource meets the physical resource required by configuring the RAN slice, the RAN slice can be created; if the usage of the physical resources does not satisfy the information of the physical resources required for configuring the RAN slice, the RAN slice cannot be created. The usage of the physical resource may include information of an idle physical resource, and the idle physical resource may include, but is not limited to, information of at least one of the following information: computing resources, storage resources, and wireless spectrum resources. It can be understood that, when the physical resources required for configuring the RAN slice include multiple physical resources, if each idle physical resource satisfies the corresponding physical resource required for configuring the RAN slice, the RAN slice can be created; the RAN slice cannot be created if the at least one idle physical resource does not satisfy the information of the corresponding physical resource required for configuring the RAN slice.

For example, if the physical resources required for configuring the RAN slice include computing resources and storage resources, in this case, if the idle computing resources and the idle storage resources both satisfy the corresponding resources required for configuring the RAN slice, the RAN slice can be created; the RAN slice cannot be created if at least one of the free computing resources and the free storage resources does not satisfy the corresponding resources required to configure the RAN slice. For example, assuming that the idle computing resources are 1 CPU, the idle storage resources are 10 gbytes, the computing resources required to configure the RAN slice are 1 CPU, and the storage resources required to configure the RAN slice are 5 gbytes, then the RAN slice can be created. As another example, assuming that the idle computing resources are 1 CPU, the idle storage resources are 10G bytes, the computing resources required to configure the RAN slice are 1 CPU, and the storage resources are 20G bytes, then although the idle computing resources are the same as the computing resources required to configure the RAN slice, the idle storage resources are less than the storage resources required to configure the RAN slice, and thus the RAN slice cannot be created.

S905: the RAN slice manager sends a creation indication message to the infrastructure controller, and the infrastructure controller receives the creation indication message sent by the RAN slice manager. Wherein, the creation indication message includes initial configuration information.

S906: the infrastructure controller creates the RAN slice according to initial configuration information included in the creation indication message.

In the present embodiment, it is considered that: the initial configuration information included in the creation indication message is all the information required by the infrastructure controller to create the RAN slice.

S907: the infrastructure controller replies a creation response message to the RAN slice manager; the RAN slice manager receives a create response message in reply to the infrastructure controller.

S908: the RAN slice manager decides whether radio spectrum resources need to be configured.

Since different RAN slices may share radio spectrum resources, the RAN slice manager may determine whether radio spectrum resources need to be configured according to configuration information of the RAN slice, taking configuration information of other RAN slices into consideration comprehensively. The embodiment of the present invention does not limit the specific implementation manner.

If yes, go to S909; if not, S911 is executed.

S909: the RAN slice manager sends wireless spectrum resource configuration information to the physical layer function module; and the physical layer functional module receives the radio spectrum resource configuration information sent by the RAN slice manager.

Specifically, the RAN slice manager sends to the terminal device, and may include but is not limited to: the RAN slice manager directly sends the RAN slice manager to the terminal equipment, or the RAN slice manager sends the RAN slice manager to the terminal equipment through the physical layer function module, or the RAN slice manager sends the RAN slice manager through the RAN slice and the physical layer function module, or the RAN slice manager sends the RAN slice manager to the terminal equipment through the public RAN slice and the physical layer function module. A common RAN slice refers to a RAN slice shared by multiple RAN slices in the system, e.g., common control channels of multiple RAN slices constitute one shared RAN slice.

S911 is performed to enable the terminal device to obtain the radio spectrum resource allocation information and use the radio spectrum resources according to the radio spectrum resource allocation information.

S912: the RAN slice manager updates the RAN slice database.

Based on the above case 1, S912 may include: the RAN slice manager updates information in the RAN slice database whether the RAN slice has been created. Based on example 1 in case 2 above, S912 may include: the RAN slice manager adds the ID of the RAN slice and the ID of the operator/service provider corresponding to the RAN slice to a RAN slice database. Based on example 2 in case 2 above, S912 may include: the RAN slice manager adds the ID of the RAN slice in the RAN slice database.

The computing resource information may include, but is not limited to, at least one of the following: idle computational resource information, information of which RAN slice the used computational resources are used by, respectively, and the like.

For example, assuming that the free storage resources in the physical resource database are 20 gbytes before the RAN slice is created, if the storage resources required to configure the RAN slice are 5 gbytes, the infrastructure controller updates the free storage resources in the physical resource database to 15 gbytes after the RAN slice is created.

S915: the RAN slice manager updates the radio spectrum resources in the physical resource database.

Wherein, the radio spectrum resource information includes but is not limited to at least one of the following information: the center frequency point and the bandwidth information of the idle wireless spectrum resources, and the configuration information of the used wireless spectrum resources. The configuration information of the wireless spectrum resource is at least one of TTI, subcarrier interval and RBG of the wireless spectrum resource of a designated central frequency point and/or a designated spectrum bandwidth.

For example, if the free radio spectrum resources in the physical resource database include two types, 1-10HZ and 21-30HZ respectively, and the physical layer function module starts to use the radio spectrum resources of 21-30HZ in S909 before performing S910, the RAN slice manager updates the free radio spectrum resources in the physical resource database to 1-10HZ in S915.

In the embodiment of the present invention, the execution order of S912, S913 to S914, and S915 is not limited.
