Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
In the following description, a user or user equipment is a terminal device used to receive data, including but not limited to mobile stations, cell phones, smart phones, etc. and other types of communication devices accessing a wireless network, such as sensors, instruments, drones, robots, etc. The access network refers to an access device for accessing user equipment to a wireless network, and includes a GSM base station, an enhanced node B (enodeb), a node B, a base station controller, and the like.
Virtual Base-Station (VBS) refers to a traditional Base Station architecture virtualized into multiple Virtual Base stations by means of software virtualization. For example, for a Centralized base station architecture C-RAN (Centralized, Cooperative, Cloud Radio Access Network), a certain number of Computing Units (CUs) may be collectively placed in a large central computer room, and these CUs are connected to each other in a certain structure to form a CU pool, and a certain number of CUs are virtualized to be a virtual base station. The establishment strategy and establishment procedure for the virtual base station are in the prior art and will not be described in detail herein.
In the invention, the goal of slice control at the access network side is to establish the association relationship between the virtual base station and the slice, so as to realize slice virtualization at the access network side. Fig. 1 shows an access network side slice virtualization network architecture diagram and four slicing approaches according to one embodiment of the invention.
Referring to fig. 1, in this embodiment, the following four types of slicing manners are designed according to the slicing requirement factors (e.g., coverage, peak throughput, peak user number, etc.) and the processing capability of the virtual base station.
The slicing mode 1 means that one Slice only shares one virtual base station, such as Slice1 in the figure. The type can be applied to a scene that the coverage of a certain slice demand and/or the number of service users can be satisfied by 1 virtual base station, and the virtual base station is almost at full load when the number of service users reaches a peak value.
The slicing mode 2 refers to that one slice only shares a plurality of virtual base stations, for example, slice 2. the coverage and/or the number of service users of the type suitable for a certain slice need a plurality of virtual base stations to meet, and may need virtual base stations of a plurality of systems (for example, WCDMA, TD-SCDMA, TDD-L TE, FDD-L TE, etc.), and meanwhile, each virtual base station is almost at full load when the number of service users reaches a peak value, and the time when the plurality of virtual base stations reach full load is not different so as to ensure load balance.
The slicing mode 3 means that a plurality of slices share one virtual base station, such as Slice3 and Slice 4. The type is applicable to a scenario when the coverage and/or the number of service users required by two or more slices can be satisfied by 1 virtual base station, and when the total number of service users of two slices reaches a peak, the virtual base station is almost at full load.
The slicing mode 4 refers to that multiple slices share multiple virtual base stations, such as Slice5 and Slice 6. The coverage range and/or the number of service users which are suitable for the requirements of two or more slices of the type need to be met by a plurality of virtual base stations, multiple standards are possibly needed, each virtual base station is almost at full load when the number of service users reaches a peak value, and the time difference of the virtual base stations reaching the full load is not much so as to ensure load balance. In addition, for a certain virtual base station, the peak values of two associated slices or two service user numbers do not coincide, or the peak user number almost coinciding among the two slices or two service user numbers is less than or equal to the capacity of the virtual base station for full load.
By dividing the affiliation between the slice and the base station into different types, the requirements of the slice can be flexibly met and the resources of the virtual base station can be fully utilized.
In addition, in slice management, a sharing mode of radio resources between slices also needs to be considered, and optionally, the invention has three modes, namely a dynamic allocation mode, a fixed allocation mode and an enhanced allocation mode. The fixed allocation mode refers to that the slice uses wireless resources according to a fixed proportion or a fixed frequency band, and service demand factors and the like are not considered. The dynamic allocation mode refers to that factors such as service requirements are considered, when the actual service requirements of the slices are less than or equal to the resource amount signed by the service agreement, allocation is carried out according to the requirements, and when the actual service requirements of the slices are greater than the resource amount signed by the service agreement, allocation is carried out according to the service agreement. The enhanced allocation mode refers to further considering the priority of the slice (as available from the service provider/operator, i.e., SAP), the priority of the user (also available from SAP) to optimize the radio resource allocation.
The invention can be flexibly configured according to actual requirements by designing different types of segmentation modes and wireless resource allocation modes so as to be suitable for different application scenes.
According to an aspect of the present invention, a slice management and control system for an access network side is provided. The slice management and control system can manage and control the access network side slices according to the requirements (namely SAP) of a third-party service provider/operator, and the functions comprise determining the attribution relationship of the slices of the virtual base station; establishing an incidence relation between the slices and the corresponding virtual base stations; allocating radio spectrum resources to each slice, etc.
For example, in the embodiment of fig. 2, the slice administration system 200 includes a slice parameter configuration module 210, a slice administration module 220, and a virtual base station administration module 230.
The slicing parameter configuration module 210 is configured to formulate a slicing policy based on the network demand information.
The network requirement information reflects the user's expectations for the performance of the services that the network is capable of providing, including latency (e.g., 50ms, 100ms), bandwidth (e.g., 20M), capacity (e.g., 100Mbps), security level, and battery life (e.g., desired battery duration), among others. The network requirement information is typically determined by a service provider/operator (i.e., SAP) according to the type of service initiated by the user or the type of service subscribed by the user, and is sent to the access network.
The slicing parameter configuration module 210 may reasonably allocate slicing resources or formulate a slicing policy according to the obtained network demand information, so as to provide a satisfactory service for the user, thereby ensuring the network experience of the user.
In one embodiment, the slicing resources/slicing policies include, but are not limited to: the number of slices, the slicing mode, and the parameters related to the virtual base station to which the slices belong, such as the resource proportion reserved for the slices to which the virtual base station belongs.
In another embodiment, the slice policy may further include a sharing mode of inter-slice wireless resources, e.g., a dynamic allocation mode, a fixed allocation mode, an enhanced allocation mode, etc. By allocating the sharing mode of the wireless resources among different slices, the network resources can be utilized to the maximum extent on the basis of meeting the requirements of users.
In addition, the slice parameter configuration module 210 may also provide interfaces with other functional modules, for example, wireless capability parameters of the access network for receiving network requirements from other modules or acquiring feedback from other modules, and the like.
In yet another embodiment, in order to make the assigned slicing policy more consistent with the capability of the access network, so as to avoid an abnormality or a failure caused by the fact that the slicing resources exceed the carrying capability of the base station, the slicing policy may be further formulated in combination with radio capability parameters, for example, the slicing policy may be formulated in combination with the number of available virtual base stations, the available spectrum bandwidth configuration, and the like.
In addition, when the SAP network requirement changes, the slicing parameter configuration module 210 may update the allocated slicing policy, for example, update the slicing manner. Through the updating mode, the network slice can meet the dynamic requirements of the user, for example, for a certain service requirement temporarily proposed by the user, the access network has the capacity of dynamically allocating the slice strategy, so that the utilization rate of network resources is improved.
The slice management and control module 220, the parameter configuration module 210 and the virtual base station management and control module have interfaces, and functions of the slice management and control module 220, the parameter configuration module 210 and the virtual base station management and control module include creating, releasing, updating, slice initialization configuration and the like of slices through information interaction with virtual base stations, so as to establish mapping relationships between slices and virtual base stations.
For example, according to the mapping relationship between the slices and the virtual base stations, tags such as P L MN, service types, etc. to which the virtual base stations belong are set, for example, when the user demand changes and the user does not match with an access network slice, the virtual base station management and control module 230 receives feedback information of the user, and reports the error feedback to the slice management and control module 220.
For example, the virtual base station management module 230 configures the virtual base station to which the slice belongs by using the virtual base station resource related information in the slice policy. For example, the virtual base station is configured to use 80% of the spectrum resources for the slice. For another example, when a plurality of slices share one virtual base station, the virtual base station is configured with the allocation ratio of the spectrum resources for each slice, and the like.
In summary, the slice parameter configuration module 210 is configured to formulate a slice resource-related policy; the slice management and control module 220 is used for flow management and control in the slice creation process; the virtual base station management module 230 is configured to configure a virtual base station. The module division mode based on the function can realize network virtualization at the access network side, manage and control the slices of the access network. The method can ensure that the logic functions of the modules are relatively single and independent, thereby reducing the coupling degree between the modules and the complexity of implementation.
It will be appreciated by those skilled in the art that various modifications can be made to the division of the functional blocks described above without departing from the spirit and scope of the invention. For example, integrated as one functional module to uniformly manage slices of the access network.
The information interaction and parameter passing process between the functional modules shown in fig. 2 will be described below with reference to fig. 3. In fig. 3, the information interaction and parameter transmission process among modules in the slice control process at the access network side is divided into three stages: a slice initialization creation phase S310, a traffic distribution phase S320 and a slice update phase S330.
21) S310, a slice initialization creating stage.
Steps 1 to 8 of fig. 3 show a flow chart of the functions and information interaction performed by the modules during the slice initialization creation phase.
In step 1, the slice parameter configuration module receives a network requirement message from a virtual network operator or a service provider. Network requirements include, for example, parameters such as latency, bandwidth, security, capacity, and battery life.
In step 2, the slice parameter configuration module configures the relevant slice parameters/slice policies.
For example, the slice-related parameters include application information, slice type, slice capacity information, limitation conditions, and the like. The application information refers to the diversified characteristics of service transmission requirements (such as network bandwidth, time delay and throughput); the slice type refers to the above inter-slice radio resource sharing mode (e.g., dynamic allocation mode, fixed allocation mode, enhanced allocation mode); the slice capacity information refers to personalized parameters of the virtual base station, such as resource reservation proportion, resource allocation proportion and the like; the constraint refers to some other constraint that sets the slice resource.
In step 3, the slice parameter configuration module sends a slice creation request message to the slice management and control module.
The slice creation request message may include configured slice resources, such as the number of slices, the slicing manner, and the like.
In step 4, the slice management and control module performs slice initialization according to the received slice creation message, and the slice initialization is completed: and generating a slice ID, and configuring a virtual base station ID to which the slice belongs.
In step 5, the slice management and control module sends the virtual base station personalization parameters to the virtual base station management and control module, for example, a virtual base station creation request and/or an existing virtual base station parameter configuration request message and the like are passed through.
In step 6, the virtual base station management and control module initializes the virtual base station, that is, generates a customized virtual base station according to the personalized parameters of the virtual base station and some default parameters, or updates the configuration of the relevant parameters of the generated virtual base station.
In step 7, the virtual base station management and control module feeds back a virtual base station creation completion or configuration update completion message to the slice management and control module.
In step 8, the slice creation is completed and the slice administration module saves and maintains the slice instance.
22) S320, data transmission phase.
Steps 9 to 17 of fig. 3 show a schematic flow chart of starting data transmission or traffic transmission after the slice creation is completed.
In step 9, the slice management and control module learns that downlink traffic arrives, for example, core network traffic arrives at the access network.
In step 10, the slice management and control module screens the slice to which the service should belong according to the network slice ID and notifies the associated virtual base station.
In step 11, the virtual base station to which the slice belongs is determined according to the mapping table of the slice and the virtual base station label, and a mapping relationship between the slice and the virtual base station is established.
In step 12, the slice management and control module may adjust slice resources according to the monitored network conditions, and notify the associated virtual base station of the new slice resources.
For example, the slice control module may adjust the resource proportion occupied by the slice according to actual traffic, throughput, time delay, and the like, where the resource proportion occupied by the slice always complies with a radio resource sharing principle, and the resource sharing principle is the above four segmentation methods and the principle of sharing slice control, virtual resource layer, and physical resource layer.
In step 13, the virtual base station management and control module updates resources according to the resources adjusted as needed.
In steps 14 to 16, downlink traffic transmission is started, and data is transmitted to the user.
In step 17, during service transmission, when the data transmitted by the service is not matched with the user information or the data cannot be transmitted to the user, the user feeds back error information to the virtual base station control, and reports the error step by step until the correct issued data is obtained.
23) S330, slice updating stage
Steps 18 to 27 of fig. 3 schematically show a flow chart of slice updating.
The slice management and control module monitors the network state in real time, and when the current slice cannot meet the user requirement or the SAP network requirement change, the slice parameter configuration module reconfigures slice resources and sends slice updating information to the virtual base station management and control module step by step to update the current slice. For example, the new slice resource may be sent to the slice control module through the slice update/slice reconstruction request message in step 21, and the slice control module sends to the relevant virtual base station through the virtual base station change request message in step 22. Other processes are basically similar to the process of slice initialization creation and are not described in detail herein.
For further understanding of the present invention, the following further describes the slice generation and data transmission control flow of the slicing scheme 3 (i.e. multiple slices share one virtual base station). As shown in fig. 4, for the slicing mode 3, it can be assumed that this shared virtual base station is divided into two logical virtual base stations, and two virtual networks, i.e. two slices, are formed with other related modules. Taking spectrum resource allocation as an example, spectrum resources are allocated according to slice requirements, and sharing of the spectrum resources by two slices is achieved.
Fig. 5 schematically shows a flowchart of the creation of slices and data transmission based on the slicing scheme 3.
For comparison, functionally equivalent steps in fig. 5 and 3 are identified with the same reference numerals. Different from the flow illustrated in fig. 3, the slice parameter configuration module receives network requirements from the SAP1 and the SAP2 (see step 1a and step 1b), configuration and creation of two slice resources need to be completed (see step 2 and step 3), and since two slices share one virtual base station, the slice management and control module needs to allocate allocation proportions of spectrum resources of the two slices, for example, the configuration is 2: 3 (see step 4), the other steps are similar to those shown in fig. 3 and will not be described in detail.
In summary, the slice management and control system designed by the invention can satisfy the basic functions of slice management and control, and when the SAP network requirements change, the information processing flow is not changed, but only the parameter configuration information contained in the transmission information is updated.
The slice management and control system of the present invention may be applied to a general mobile communication network architecture, for example, a super base station architecture as shown in fig. 6 or a radio access network (C-RAN) architecture (not shown) based on an open platform real-time cloud infrastructure.
Accordingly, in another aspect, the present invention further provides a slice management and control method for an access network side, as shown in fig. 7.
1) Step S710, acquiring a network requirement.
The network requirement information reflects the user's expectations for the performance of the services that the network is capable of providing, including, for example, latency, bandwidth, security, capacity, and battery life. The network requirement information is typically determined by a service provider/operator (i.e., SAP) according to the type of service initiated by the user or the type of service subscribed to by the user and sent to the access network.
2) Step S720, determining a slicing strategy based on the network requirement.
Slice resources can be reasonably distributed or slice strategies can be formulated according to the obtained network demand information so as to provide satisfactory service for users, and therefore network experience of the users is guaranteed.
In addition, when the SAP network requirements change, the slicing policy may be updated, for example, the slicing manner may be updated. In this way, the "network slice" can satisfy the dynamic requirements of the user, for example, for a certain service requirement temporarily proposed by the user, the access network has the capability of dynamically allocating resources, thereby improving the utilization rate of the network resources.
3) Step S730, a mapping relationship between the slice and the virtual base station is established based on the slice policy.
For example, when a slice of the access network is newly established, a mapping relationship between the slice and the virtual base station can be established based on the slicing mode in the slicing strategy, and the step is used for informing the slice to which the virtual base station belongs, the P L MN to which the virtual base station belongs, and the like.
4) Step S740, configuring the virtual base station to which the slice belongs.
In this step, the virtual base station to which the slice belongs is configured by using the virtual base station resource related information in the slice policy. For example, the virtual base station is configured to use 80% of the spectrum resources for the slice. For another example, when multiple slices share one virtual base station, the allocation ratio of the virtual base station for the spectrum resources of each slice is configured.
Having described embodiments of the present invention, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen in order to best explain the principles of the embodiments, the practical application, or improvements made to the technology in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
