Detailed Description

For the purposes of promoting an understanding of the principles and advantages of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same.

It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present disclosure should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present disclosure pertains. The terms "first," "second," and the like, as used in embodiments of the present disclosure, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.

Network slicing (Network policies) may refer to virtually cutting a Network, providing multiple logical networks, each serving a particular traffic type or industry user. Each network slice can flexibly define logic topology, service level requirements, reliability and security level to meet the differentiated requirements of different businesses, industries or users. The operator can reduce the cost of constructing a plurality of private networks through network slicing, and can provide highly flexible network services which are allocated according to the needs of the service, thereby improving the network value and the rendering capability of the operator and assisting the digital transformation of various industries. Three major core application scenarios for current 5G technology may include enhanced mobile broadband (eMBB): greater network throughput, peak rate, and low latency; mass machine communication (mctc): the huge connection quantity is used for supporting mass terminals of the Internet of things; high reliability low latency communication (uRLLC): the core is concerned with high reliability and ultra low latency of the network. Accordingly, the network can be partitioned into three major classes of network slices, namely, emmbc, emtc, and ullc. And selecting applicable slice categories in the URSP rule by different services according to the application scene of the service. Because the URSP rule is relatively fixed, the slice resources adopted by the service are relatively fixed, and flexible and dynamic selection of different slice resources according to the self requirements of the terminal cannot be realized. Moreover, both the terminal and the operator network must support the urs function due to the need to use urs rules. Meanwhile, the terminals all use shared network slices of the operator network, so that physical transverse isolation cannot be completely realized, and the safety and reliability of the service are reduced. Therefore, how to realize the flexible and dynamic selection of the network slice according to the personalized requirements of the terminal, and adaptively reselect the network slice without participation of a common carrier when the requirements of the terminal change, and enhance the reliability and the security of the terminal service are technical problems to be solved.

In view of this, embodiments of the present disclosure provide a network slice-based communication method, apparatus, device, storage medium, and program product. And determining a corresponding special network slice according to the service elements of the terminal service and the current state of the terminal to establish session connection so as to realize data transmission of the terminal service. The requirements of the terminal for flexibly and dynamically selecting different slice resources according to the requirements of the terminal can be met; meanwhile, the special network slice corresponding to the terminal is used, so that the terminal service is physically and transversely isolated, and the safety and reliability of the terminal service are ensured.

Referring to fig. 3, fig. 3 shows a flow diagram of a network slice based communication method according to an embodiment of the present disclosure. In fig. 3, a network slice based communication method 300 may include the following steps.

In some embodiments, the network slice may comprise a dedicated network slice dedicated to the terminal.

Where a dedicated network slice may refer to a network slice dedicated for use by a specified terminal or terminals. That is, the designated one or more terminals may access the dedicated network slice and perform data transmission based on the dedicated network slice to implement the corresponding service; while other terminals (i.e., non-designated terminals) cannot access the private network slice. The private network slice may be determined by a user of one or more terminals negotiating with the network operator. The users of the one or more terminals may include enterprise users, which may have one or more enterprise terminals, and/or individual users, which may also have one or more individual terminals. For example, the enterprise user_e1 has an enterprise terminal t_e1, and the enterprise user_e1 can determine slice resource types type1, type2, type3 (for example eMBB, mMTC, uRLLC) and an carrying capacity type1 of each slice resource required by the enterprise terminal t_e1 according to its own service characteristics: capability 1, type2: capability 2, type3: capability 3, the enterprise user user_e1 may negotiate with the network operator, and set a network slice1 with type1 and capability of capability 1, a network slice2 with type2 and capability of capability 2, and a network slice3 with type3 and capability of capability 3 in the network slices as a dedicated network slice of the enterprise user user_e1. Then, the private network slice is also the private network slice of the enterprise terminal t_e1 of the enterprise user_e1. For another example, the enterprise user user_e1 has an enterprise terminal t_e1, the enterprise user user_e2 has enterprise terminals t_e2a and t_e2b, and the enterprise user user_e1 and the enterprise user user_e2 may be the same industry or different industries. The enterprise user user_e1 and the enterprise user user_e2 can determine slice resource types type1, type2, type3 (for example eMBB, mMTC, uRLLC) and the carrying capacity type1 of each slice resource required by the enterprise user user_e1 and the enterprise user user_e2 according to their own business characteristics: capability 1, type2: capability 2, type3: the capability 3, the enterprise users user_e1 and user_e2 may negotiate with the network operator, and the network slice1 with type1 and capability 1, the network slice2 with type2 and capability 2, and the network slice3 with type3 and capability 3 are set as the dedicated network slices of the enterprise users user_e1 and user_e2. Then, the private network slice is also a private network slice of the enterprise terminal t_e1 of the enterprise user_e1 and the enterprise terminals t_e2a, t_e2b of the enterprise user_e2. Therefore, the terminal and the network do not need to use URSP functions because the terminal can use the corresponding special network slice, and the deployment complexity of the terminal and the network is reduced.

In some embodiments, the types in the network slice may include, but are not limited to: eMBB, mctc, or wrlc.

In practical application, referring to fig. 4, fig. 4 shows a schematic diagram of a network slice based communication method according to an embodiment of the present disclosure. In fig. 4, the terminal 410 is initialized when powered on, and may initiate a registration request to an operator network 420 provided by a network operator to request alternative slice information, where a dedicated network slice corresponding to the slice information may be determined by a negotiation between a user of the terminal and the network operator. For example, a user of the terminal (e.g., an enterprise user of an industrial terminal, a personal user of a personal terminal) may negotiate with a network operator according to its own needs and situation, a slice type of a required dedicated network slice, performance of a slice bearer, tariffs, etc., and dedicated slice information corresponding to the dedicated network slices, e.g., S-nsai, etc.

The operator network 420 returns a registration success message to the terminal 410 along with the optional slice information. Because the URSP function is not required to be used, the terminal and the network can be free from the URSP function, and the deployment complexity of the terminal and the network is reduced.

When the terminal 410 needs to perform service a, a corresponding service request a may be initiated, e.g. sent to the second slice management device 430 via the first slice management device 411 in the terminal 410. The second slice management apparatus 430 provided in the 5G integrated management platform returns a response a for requesting the current state information 412 of the terminal to the terminal 410 in response to the service request a.

After receiving the response a, the first slice management apparatus 411 of the terminal 410 transmits the current state information 412 of the terminal 410 to the second slice management apparatus 430. The second slice management apparatus 430 determines a dedicated network slice a (not shown) applicable to the service a and its corresponding network slice information Info _ slice a based on the service elements in the service request a and the current state information 412 of the terminal 410. The network slice information Info _ slice a may be S-nsai information (Single Network Slice Selection Assistance Information, single slice selection assistance information), which may be a representation of a terminal side network slice for network and terminal identification of one network slice resource. NSSAI is a set of S-NSSAIs, which may be configured NSSAIs, requested NSSAIs, or allowed NSSAIs. The second slice management apparatus 430 transmits the network slice information Info _ slice a to the terminal 410.

After receiving the network slice information info_slice a, the first slice management apparatus 411 in the terminal 410 establishes session connection sessionA based on S-NSSAI information in the network slice information info_slice a to carry traffic. Since the terminal 410 uses network slices through a session connection (e.g., PDU session, PUD session), the terminal 410 may carry S-nsai information when initiating the establishment of the session connection may indicate a dedicated network slice sla to be used. Compared with the traditional method that only relatively fixed slice resources can be determined based on URSP rules, the method of the embodiment of the disclosure realizes that a user of a terminal can intelligently, flexibly and dynamically select different slice resources according to specific requirements of current services and current states of the terminal.

It should be understood that the slice management apparatus 430 may be disposed at the server side or at the terminal, which is not limited herein.

In step S301, a first service element concerning a first service is acquired.

The first service may refer to a service to be executed by the terminal, for example, service a in fig. 4. The first service element may refer to an information element related to performing the first service.

In some embodiments, the first service element may include at least one of the following with respect to the first service: service execution time, service type, urgency, importance, rate requirements, reliability requirements, or slicing tariff requirements. The service execution time may refer to a time or a period of time for executing the service. The traffic types may include an eMBB type, an emtc type, or a uirllc type; further, the emmbc type, the emtc type, or the ullc type may be further subdivided into at least one first type, at least one second type, at least one third type, respectively; that is, the eMBB type may include at least one first type, the emtc type may include at least one second type, and the uirllc type may include at least one third type.

In step S302, first information including the first service element and current state information of the terminal is transmitted.

The current state information of the terminal may include terminal environment information and terminal operation information. The terminal environment information may refer to current environmental parameters of the location of the terminal, such as location, temperature, humidity, etc. The current state information of the terminal may refer to current operating parameters of the terminal.

In some embodiments, transmitting the first information including the first service element and the current state information of the terminal may include:

transmitting a first service request (e.g., service request in fig. 4) including a first service element;

receiving a first service response (e.g., response in fig. 4) to the first service request, the first service response being for requesting the current state information (e.g., current state information 412 in fig. 4) from the terminal;

and sending the current state information.

As shown in fig. 4, the first slice management apparatus 411 in the terminal 410 sends the first service request to the second slice management apparatus; the second slice management apparatus 430 transmits a first service response to the terminal 410 in response to the first service request; the first slice management apparatus 411 transmits current state information of the terminal 410 to the second slice management apparatus 430 in response to the first service response.

In step S303, a first response to the first information is received, the first response comprising first slice information of a first one of the private network slices determined based on the first service element and the current state information.

The slice information of the network slice which is specifically applicable in the special network slice can be determined according to the service elements of the service and the current state information of the terminal. As shown in fig. 4, the second slice management apparatus 430 may acquire correspondence relation between the current state information of the terminal and the dedicated network slice according to the service elements of the service, for example, as shown in table 1.

TABLE 1

In table 1, it can be determined that the service is applicable to the private network slice of slice information 1 according to the service type of service 1, time of 0:00, location of L1, temperature of-5 degrees, emergency degree of emergency, and importance degree of importance. Similarly, the service type is service 2, the time is 14:00, the location is L2, the temperature is 16 degrees, the emergency degree is not emergency, the importance degree is not important, and the service is determined to be applicable to the special network slice of slice information 2; the service type is service 2, the time is 14:00, the location is L2, the temperature is-5 ℃, the emergency degree is not emergency, and the importance degree is important, and the service is determined to be suitable for the special network slice of slice information 2. It should be appreciated that the correspondence between the service elements of the service, the current state information of the terminal, and the dedicated network slice may be dynamically adjusted based on a self-feedback manner. For example, a quality of service value may be set for the quality of service of the service data transmission, and the correspondence between the service element, the terminal state information and the network switch is preset in the initial state, but the preset is not necessarily reasonable, and dynamic adjustment is required according to the quality of service in use of a specific service. When the service runs along with time and the service quality value is reduced, the service quality value is fed back to the management device, and the management device changes the corresponding relation between the service element and the terminal state information and the network slice according to the current service quality, namely, the current service element and the terminal state information correspond to the network slice with higher service quality. The adjusted correspondence may be stored and may be obtained when the second slice management 430 performs allocation of the network slice.

In fig. 4, the second slice management 430 may determine that the first service is applicable to a first private network slice among the private network slices based on the received first service element and the current state information, and transmit the first slice information of the first private network slice to the terminal 410 included in the first response. The first slice management apparatus 411 in the terminal 410 receives the first response from the second slice management apparatus 430, and may acquire the first slice information from the first response.

In some embodiments, the method 300 may further comprise:

if a private network slice applicable to a first service cannot be determined based on the first service element and the current state information, determining that the first service is applicable to a default private network slice.

When the special network slice suitable for the first service cannot be determined according to the service elements of the service, the corresponding relation between the current state information of the terminal and the special network slice, a default special network slice can be set for bearing the first service, so that the execution of all the services of the terminal is ensured.

In step S304, a first session connection is established with the first private network slice based on the first slice information for data transmission with respect to the first service.

In some embodiments, the first slice information may include S-NSSAI information. Wherein the S-nsai information includes an SST field and an SD field, the SST field may indicate a slice and a service type of the S-nsai information, indicating a network slice behavior expected in terms of functions and services; while the sst-SD field may indicate the slice, composition of the service type, and slice component of the S-NSSAI information. One network slice instance may be associated with one or more s-NSSAI information, and one s-NSSAI information may be associated with one or more network slice instances.

In some embodiments, the first session connection may be a PDU session connection.

Specifically, as shown in fig. 4, after receiving the first slice information, the first slice management apparatus 411 in the terminal 410 establishes a session connection based on the first slice information to carry the service. Therefore, the user of the terminal can intelligently, flexibly and dynamically select different slice resources according to the specific requirements of the current service and the current state of the terminal. Meanwhile, the special network slice corresponding to the terminal is used, so that the terminal service is physically and transversely isolated, and the safety and reliability of the terminal service are ensured.

In some embodiments, the method 300 may further comprise:

acquiring a second service element related to a second service;

transmitting second information including the second service element and current state information of the terminal;

receiving a second response to the second request, the second response including the first slice information determined based on the second business element and the current state information;

and transmitting data about the second service based on the first session connection.

Wherein, similar to the first service, when the terminal 410 in fig. 4 needs to execute the second service B, a corresponding second service request B may be initiated, for example, the service request B is sent to the second slice management device 430 via the first slice management device 411 in the terminal 410. The second slice management apparatus 430 returns a response b for requesting the current state information 412 of the terminal to the terminal 410 in response to the service request b. After receiving the response b, the first slice management apparatus 411 of the terminal 410 transmits the current state information 412 of the terminal 410 to the second slice management apparatus 430.

If the second slice management apparatus 430 determines a dedicated network slice B and its corresponding network slice information Info _ slice B applicable to the second service B based on the service elements in the service request B and the current state information 412 of the terminal 410. The second slice management apparatus 430 transmits the network slice information Info _ slice b to the terminal 410. After receiving the network slice information info_sliceb, the first slice management apparatus 411 establishes session connection session B with the dedicated network slice sliceB based on the S-nsai information in the network slice information info_sliceb, so as to carry the second service B.

If the second slice management apparatus 430 determines a dedicated network slice sla and its corresponding network slice information Info _ sla applicable to the second service B based on the service elements in the service request B and the current state information 412 of the terminal 410. At this point, the second traffic B may be carried using the session connection sessionA that has been established with the dedicated network slice sliceA. Therefore, the established session connection on the same special network slice is adopted to bear the service, the establishment time of the session connection is reduced, and the communication efficiency and response time are further improved.

In some embodiments, the traffic types of the first traffic and the second traffic may be the same. Wherein, for different specific services with the same service type, the established session connection on the same special network slice can be used for bearing the service.

In some embodiments, the method 300 may further comprise:

judging whether the first business element and/or the current state information is changed or not;

transmitting change information in response to the change of the first business element and/or the current state information, wherein the change information comprises the changed first business element and/or the changed current state information;

Receiving a third response to the change information, the third response including second slice information for a second one of the private network slices determined based on the change information;

and establishing a second session connection with the second special network slice based on the second slice information so as to perform data transmission on the first service.

Wherein, the current state information of the terminal and/or the service elements of the service selection slice change, which may cause that the service needs to select the slice again, so that the slice resource of the current bearing service changes. Referring to fig. 5, fig. 5 shows a schematic diagram of a network slice change according to an embodiment of the present disclosure. In fig. 5, the first slice management device 411 in the terminal 410 has established a first session connection session with the first private network slice a, which carries the first service a of the terminal 410. When the first service element of the first service a is changed, the first slice management apparatus 411 transmits the changed first service element to the second slice management apparatus 430. The second slice management apparatus 430 determines that the dedicated network slice applicable to the current first service a is sliceB based on the changed first service element and the current state information, and then sends network slice information info_sliceb of the dedicated network slice sliceB to the first slice management apparatus 411. The first slice management apparatus 411 receives the network slice information info_slice b, and may establish a session connection session b with the dedicated network slice b based on the network slice information info_slice b to carry the first service a.

When the current status information of the terminal 410 is changed, the first slice management apparatus 411 transmits the current status information after the terminal change to the second slice management apparatus 430. The second slice management apparatus 430 determines that the dedicated network slice applicable to the current first service a is sliceC based on the changed current state information and the first service element, and then sends network slice information info_slicec of the dedicated network slice sliceC to the first slice management apparatus 411. The first slice management apparatus 411 receives the network slice information info_slicec, and may establish a session connection session c with the dedicated network slice sliceC based on the network slice information info_slicec to carry the first service a.

When both the first service element and the current status information of the terminal 410 are changed, the first slice management apparatus 411 transmits the changed first service element and the changed current status information to the second slice management apparatus 430. The second slice management apparatus 430 determines that the dedicated network slice applicable to the current first service a is slice d based on the changed first service element and/or the changed current state information, and transmits network slice information info_slice of the dedicated network slice d to the first slice management apparatus 411. The first slice management apparatus 411 receives the network slice information info_slice d, and may establish a session connection session d with the dedicated network slice based on the network slice information info_slice to carry the first service a.

As can be seen, the first slice management device 411 in the terminal 410 in fig. 5 determines whether the first service element and/or the current state information is changed, and if the first service element and/or the current state information is changed, sends the change information (for example, the changed first service element and/or the changed current state information) to the second slice management device 430. The second slice management apparatus 430 determines that the modified first service a is applicable to the second dedicated network slice (for example, sliceB-sliceD) based on the appropriate parameters in the modification information, the first service element before modification, and the current state information before modification (for example, when only the first service element is modified, the network slice resource is determined by using the modification information and the current state information before modification; when only the current state information is modified, the network slice resource is determined by using the modification information and the first service element before modification, and when both the first service element and the current state information are transmitted to be modified, the network slice resource is determined by using the modification information), and the network slice information is the second slice information (for example, info_sliceb-info_sliced). The second slice management apparatus 430 transmits the second slice information to the first slice management apparatus 411, and the first slice management apparatus 411 establishes a second session connection (e.g., session b-session d) with the second private network slice based on the second slice information to perform data transmission with respect to the first service a. Therefore, according to the method of the embodiment of the disclosure, the dynamic adjustment of the slice resources can be automatically performed according to the actual conditions of the service and the terminal without participation of a network operator, so that different network slice resources can be intelligently and flexibly selected, and the intelligent and flexible reasonable allocation of the network slice resources is improved.

In some embodiments, the method 300 may further comprise:

judging whether the first session connection carries data transmission or not;

and releasing the first session connection in response to the first session connection not carrying data transmission.

In order to improve the utilization rate of network slice resources, the established session connection can be released when no service is carried on the session connection. Since a new session connection is established for the changed first service a in fig. 5, the original first session connection established with the first dedicated network slice may be released if it does not carry data transmission of any service, so as to reduce occupation of network slice resources.

In some embodiments, the network slice further comprises a shared network slice, and the method 300 may further comprise:

acquiring a first service descriptor about a third service;

determining shared slice information of the shared network slice based on the first traffic descriptor and the urs rule information;

judging whether third session connection exists between the terminal and the shared network slice;

and establishing a fourth session connection with the shared network slice based on the shared slice information to perform data transmission on the third service in response to the third session connection not being present between the terminal and the shared network slice.

In some embodiments, the method 300 may further comprise:

and in response to the existence of the third session connection between the terminal and the shared network slice, performing data transmission on the third service based on the third session connection.

For the terminal, not all services need to adopt special network slicing to ensure the security and reliability of data, and for the services with low security requirements, the service requirements can be realized by the shared slicing network of the network operator, so that the cost is reduced. That is, some services of the terminal may use dedicated network slices, and some services may use shared network slices of the network operator.

In some embodiments, the method 300 may further comprise:

a determination is made that the first service uses a shared network slice or a private network slice based on a service attribute of the first service.

Wherein the service attribute comprises one or more attribute values, and different attribute values can correspond to different slice selection modes. The mapping relationship may be formed based on the service attribute and the corresponding slice selection manner, as shown in table 2 below:

service	Business attributes	Slice selection scheme
			Service A	Ordinary business	Shared network slice
Service B	Industry business	Special network slice
			Service C	Industry business	Special network slice
Service D	Other business	Without any means for

TABLE 2

In table 2, if the service attribute of the service a is a common service, the service attribute may be applicable to shared network slices; the service attributes of the service B and the service C are industry services, and can be suitable for special network slicing; and if the service attribute of the service D is other services, no applicable network slice exists. Where the traffic may be set to apply to the default network slice when there is no corresponding slice selection scheme, e.g., traffic D. It can be seen that from the traffic attributes it can be determined whether the traffic uses dedicated network slices. If it is determined that the service uses a private network slice, the service may be implemented based on the private network slice based on the methods of the embodiments of the present disclosure. If it is determined that the service uses a shared network slice, the service may be implemented based on the shared network slice based on the methods of the embodiments of the present disclosure. It should be understood that the mapping relationship between the service attribute and the slice selection scheme is merely an example, and is not intended to limit the service attribute and the slice selection scheme, and the service attribute may further include more or fewer kinds, which are not limited herein.

As shown in fig. 6, fig. 6 shows a schematic diagram of a network slice-based communication method according to an embodiment of the present disclosure. In fig. 6, terminal 410 sends a registration request1 to operator network 420. The operator network 420 transmits a registration success message, which may include the urs p rule information, to the terminal 410 in response to the registration request1. The urs rule information may be used to configure and manage slices of the terminal, and to instruct the terminal to carry service data to corresponding slices according to service features. And the terminal selects matched network slices for the service according to the strategy set by the network side. The urs rule information may include traffic descriptors (Traffic descriptor), which may include IP triplets, APP IDs, DNNs, FQDNs, etc., and routing descriptors (Route Selection Descriptor) containing S-NSSAI, etc. information. And the terminal searches the matched route descriptor information in the URSP rule through the value of the service descriptor of the service, and finally acquires corresponding S-NSSAI and other slice information.

When the terminal 410 receives the oss rule information and wants to execute the third service, the service module 413 in the terminal 410 sends the first service descriptor Traffic Descriptor about the third service to the oss management module 414 in the terminal 410, and the oss management module 414 searches the matched Route Selection Descriptor information in the oss rule according to the information of the first service descriptor Traffic Descriptor, so as to obtain the shared slice information Info such as S-nsai. Then the urs p management module 414 may send network slice information Info such as S-NSSAI to the service module 413. The service module 413 may establish a session connection with the shared network slice_0 indicated by the S-nsai information in the network slice information Info. If a third session connection has been established between the traffic module 413 and the shared network slice _0, a third traffic may be carried directly on the basis of the third session connection. If no third session connection is established between the service module 413 and the shared network slice slice_0, a fourth session connection may be established to carry third traffic.

In some embodiments, the method 300 may further comprise:

the first slice information of the first private network slice corresponding to the first service is determined based on the first service element and the current state information.

The second slice management apparatus 430 in fig. 4 may also be disposed in the terminal 410. At this time, before step S303, the second slice management apparatus 430 in the terminal 410 may determine first slice information of a first dedicated network slice carrying the first service based on the first service element and the current state information of the terminal 410.
