Detailed Description
Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless it is specifically stated otherwise.
Meanwhile, it should be understood that the sizes of the respective parts shown in the drawings are not drawn in actual scale for convenience of description.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.
Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and apparatus should be considered part of the specification.
In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
As previously described, the slice management function entity deployment locations are not uniform due to the current sub-domain product or equipment maturity of each slice technology. For example, the wireless NSSMF deployment location may be collocated with OMC-R (Operations Maintenance Center for Radio, wireless base station operation maintenance system) or be combined with an upper layer network management. For both deployment modes, there is a technical problem: and if the wireless NSSMF is deployed on the OMC-R side, the upper layer network management interface and the OMC-R management interface are generally based on the NSMF-wireless NSSMF interface.
Although the characterization mode can meet the basic slice management requirement, the slice cells in the TAC range cannot be further managed, and the refinement requirement in the actual operation process cannot be met.
For example, after the private network wireless slice binding is opened, a new base station or cell needs to be added to the wireless slice; the upper network manager cannot bind and open the wireless slices of the base station or the cell in time through the interface with the OMC-R slice management interface. Similarly, because the coverage area of the TAC or the tarist cannot fully correspond to the private network coverage area in practice, in order to achieve accurate adjustment of the private network coverage area, particularly the coverage boundary, on the radio side, some cells in the TAC or the tarist need to be moved out of the radio slice range.
In view of the above technical problems, the present disclosure proposes a wireless slice adjustment method and system, when a wireless slice management interface adopts an NSMF to wireless NSSMF interface (generally, NSSMF and OMC-R are combined), enhancing Network Slice Instance Modification signaling for lifecycle management in the NSMF to wireless NSSMF interface; when the wireless slice management interface does not adopt NSMF to wireless NSSMF interface (generally NSSMF is combined with upper layer network management), cell-level slice management signaling enhancement is carried out on the wireless slice management interface.
Therefore, the problem that the upper network manager cannot finely adjust the coverage of the wireless slice after the wireless slice is bound and opened in the actual network operation stage is solved. For example, the technical solution of the present disclosure may be implemented by the following embodiments.
Fig. 1a illustrates a flow chart of some embodiments of a control-side adjustment method of wireless slicing of the present disclosure.
As shown in fig. 1a, in step 110, an adjustment structure of the coverage of the employed wireless sub-slice is determined according to the employed wireless slice management interface.
In some embodiments, where the wireless slice management interface employs an NSMF entity to wireless NSSMF entity interface, the control end of the wireless slice adjustment function may be located in the operating system. For example, an operating system may be virtualized, containing multiple slice functional entities or systems; the control end of the wireless slice adjustment function can be combined with the NSMF entity or share data information, and the receiving end of the wireless slice adjustment function can be combined with the NSSMF entity.
In some embodiments, the control end of the wireless slice adjustment function may be located in the operating system without the wireless slice management interface employing an NSMF entity to wireless NSSMF entity interface. For example, an operating system may be virtualized, containing multiple slice functional entities or systems; the NSSMF entity can be deployed in an operating system or combined with OMC-R.
In some embodiments, before step 110, the control end of the wireless slice adjustment function may prepare (e.g. acquire, calculate, determine, etc.) the basic parameter information of the wireless sub-slice coverage adjustment when performing the wireless slice coverage adjustment.
For example, the basic parameter information may include at least one of a unique identification of a cell or a base station, wireless slice identification information, PLMN (Public Land Mobile Network ), TAC, VLAN (Virtual Local Area Network, virtual local area network) ID (identification), 5QI (5G Quality of Service Identifier,5G quality of service indicator), performance, guarantee, transmission, and slice-related information.
In some embodiments, the adjustment structure of the wireless sub-slice coverage area employed is determined based on whether the wireless slice management interface employed is an NSMF entity to NSSMF entity interface.
For example, where the wireless slice management interface employed is an NSMF entity to NSSMF entity interface, an adjustment structure is determined that employs Network Slice Instance Modification to enhance wireless sub-slice coverage in signaling.
For example, in the case where the adopted wireless slice management interface is a non-NSMF entity to NSSMF entity interface, the adjustment structure is determined according to an enhanced structure of cell-level slice management of the wireless slice management interface.
In some embodiments, in the case that the adopted wireless slice management interface is a non-NSMF entity to NSSMF entity interface, adding an adjustment structure to an update signaling interface in the wireless slice management interface; or adding a cell-level slice adjustment interface signaling set as an adjustment structure in a wireless slice management interface of a TAC or TAList level.
In step 120, the adjustment structure is data-structured to generate adjustment information for the coverage of the wireless sub-slice.
In some embodiments, where the wireless slice management interface is based on an NSMF to wireless NSSMF interface, the wireless sub-slice coverage adjustment structure in Network Slice Instance Modification enhanced signaling for lifecycle management in the NSMF to wireless NSSMF interface is data structured.
In some embodiments, in the case that the wireless slice management interface is based on an NSMF to wireless NSSMF interface, the adjustment structure in the enhancement signaling is an enhancement structure, including SST (Slice or Service type ), SD (Slice Differentiator, slice differentiator), unique identification of the corresponding TAC, cell or base station, adjustment type identification (addition or deletion), and may also include other wireless slice related attributes.
For example, in the case that the wireless slice management interface is based on an NSMF-to-wireless NSSMF interface, in the enhanced structure, SST and SD are primary KEYs, unique identifiers corresponding to the TAC, the cell or the base station to which they belong, and adjustment type identifiers (addition or deletion) are mandatory attributes, and other wireless slice related attributes can be selected according to practical situations.
In some embodiments, where the wireless slice management interface is not based on an NSMF to wireless NSSMF interface, the data construction is performed in accordance with a wireless slice management interface cell level slice control enhancement structure.
In some embodiments, where the wireless slice management interface is not based on an NSMF to wireless NSSMF interface, the cell level coverage adjustment structure may be added to an update signaling interface in the wireless slice management interface. The adjustment structure needs to include SST, SD, unique identifier corresponding to the TAC, cell or base station to which the adjustment structure belongs, adjustment type identifier (adding or deleting), and other wireless slice related attributes.
For example, in the case that the wireless slice management interface is not based on the NSMF to wireless NSSMF interface, in the adjustment structure, SST and SD are primary KEYs, unique identifiers corresponding to the TAC, the cell or the base station to which they belong, and adjustment type identifiers (addition or deletion) are mandatory attributes, and other wireless slice related attributes are selected according to practical situations.
In some embodiments, where the wireless slice management interface is not based on an NSMF to wireless NSSMF interface, a cell-level slice adjustment interface signaling set may be added to the TAC or tarst level wireless slice management interface.
For example, in the case where the wireless slice management interface is not based on the NSMF to wireless NSSMF interface, a cell-level slice is added in the cell-level slice adjustment interface signaling set, cell-level slice deletion is determined as the necessary signaling, and cell-level slice query is determined as the optional signaling.
For example, in the case that the wireless slice management interface is not based on the NSMF-to-wireless NSSMF interface, the cell-level slice adding or deleting signaling structure uses the unique identifier of the cell or the base station as the primary KEY, and the attribute includes at least one of SST, SD, corresponding to the corresponding TAC, PLMN, VLAN (Virtual Local Area Network ) ID, and other wireless slice related attributes; the cell-level slice inquiry signaling takes a unique identifier of a cell or a base station as a main KEY, and the inquiry result structure is consistent with the cell-level slice adding or deleting signaling structure.
In step 130, the adjustment structure including the adjustment information is sent to the receiving end, so that the receiving end analyzes the adjustment structure to obtain and execute the adjustment information.
In some embodiments, in the case that the adopted wireless slice management interface is an NSMF entity to NSSMF entity interface, starting and calling the NSMF entity to NSSMF entity interface, and sending an adjustment structure containing adjustment information to the receiving end; and under the condition that the adopted wireless slice management interface is a non-NSMF entity-NSSMF entity interface, according to the wireless sub-slice coverage adjustment requirement, a corresponding management enhancement interface is called, and an adjustment structure containing adjustment information is sent to a receiving end.
For example, in the case that the wireless slice management interface is based on an NSMF-to-wireless NSSMF interface, a Network Slice Instance Modification signaling enhanced interface for invoking lifecycle management in the NSMF entity-to-wireless NSSMF entity interface is started, and wireless sub-slice coverage adjustment information is issued.
For example, if the wireless slice management interface is not based on the NSMF-to-wireless NSSMF interface, the corresponding management enhancement interface is invoked according to the wireless sub-slice coverage adjustment request, and the wireless sub-slice coverage adjustment information is issued.
In some embodiments, the adjustment signaling interaction is completed, and an execution result of the adjustment signaling fed back by the receiving end is obtained.
For example, in the case that the wireless slice management interface is based on an NSMF-to-wireless NSSMF interface, after the NSMF entity and the NSSMF entity complete interface authentication, the control end of the wireless slice adjustment function issues adjustment information of the wireless sub-slice coverage to the receiving end through a Network Slice Instance Modification signaling enhancement interface in the NSMF entity-to-wireless NSSMF entity interface. The wireless slice adjusting functional entity (i.e. the receiving end) can acquire (for example, can transmit through an NSSMF entity) an adjusting structure of the wireless sub-slice coverage range, and perform adjusting signaling after analyzing the adjusting structure; the receiving end feeds back the result.
For example, in the case that the wireless slice management interface is not based on the NSMF-to-wireless NSSMF interface, the wireless slice adjustment function (i.e., the control end) performs wireless sub-slice coverage adjustment signaling issuing by invoking the corresponding management enhancement interface; the wireless slice adjusting function (namely a receiving end) analyzes the wireless sub-slice coverage adjusting structure of the wireless slice management interface signaling and executes an adjusting instruction; the receiving end feeds back the result.
Fig. 1b shows a flowchart of further embodiments of a control-side adjustment method of wireless slicing of the present disclosure.
As shown in fig. 1b, in step 101b, the control end of the wireless slice adjustment function may first prepare (e.g. acquire, calculate, determine, etc.) the basic parameter information of the wireless sub-slice coverage adjustment when performing the wireless slice coverage adjustment.
For example, the basic parameter information may include at least one of a unique identification of a cell or a base station, wireless slice identification information, PLMN Public Land Mobile Network, public land mobile network), TAC, VLAN (Virtual Local Area Network ) ID (identification), 5QI (5G Quality of Service Identifier,5G quality of service indicator), performance, guarantee, transmission, and other slice-related information.
In step 102b, judging whether the wireless slice management interface is based on an NSMF entity to wireless NSSMF entity interface, if so, jumping to step 103b, otherwise, jumping to step 106b; .
In step 103b, data construction is performed on the wireless sub-slice coverage adjustment structure in Network Slice Instance Modification enhanced signaling for lifecycle management in NSMF to wireless NSSMF interface.
In step 104b, a Network Slice Instance Modification signaling enhanced interface for invoking lifecycle management in the NSMF entity-to-wireless NSSMF entity interface is started, and wireless sub-slice coverage adjustment information is issued.
In step 105b, the adjustment signaling interaction is completed, and the execution result of the adjustment signaling fed back by the receiving end is obtained.
In step 106, data construction is performed according to the radio slice management interface cell level slice control enhancement structure.
In step 107b, a corresponding management enhancement interface is invoked according to the wireless sub-slice coverage adjustment request, and wireless sub-slice coverage adjustment information is issued. After completion, the process goes to step 105b.
Fig. 2a illustrates a flow chart of some embodiments of a receiver adjustment method of a wireless slice of the present disclosure.
As shown in fig. 2a, in step 210, an adjustment structure of a wireless sub-slice coverage area adopted by the control end is determined according to the adopted wireless slice management interface.
In some embodiments, it may be determined whether the control end has a request for adjustment of the coverage of the wireless sub-slice; if yes, judging whether the wireless slice management interface is based on NSMF to wireless NSSMF interface; if not, the slave determines whether to make an adjustment request.
In some embodiments, the adjustment structure of the wireless sub-slice coverage area adopted by the control end is determined according to whether the adopted wireless slice management interface is an NSMF entity to NSSMF entity interface.
For example, in the case that the adopted wireless slice management interface is an NSMF entity to NSSMF entity interface, an adjustment structure adopted by the control end to adjust the wireless sub-slice coverage in the enhancement signaling for the network slice instance is determined.
For example, in the case that the adopted wireless slice management interface is a non-NSMF entity to NSSMF entity interface, the adjustment structure adopted by the control end for cell-level slice management of the wireless slice management interface is determined.
In some embodiments, where the wireless slice management interface is based on an NSMF entity to wireless NSSMF entity interface, the wireless sub-slice coverage adjustment structure in Network Slice Instance Modification enhanced signaling for lifecycle management in the NSMF entity to wireless NSSMF entity interface is data parsed.
In some embodiments, the wireless sub-slice coverage adjustment structure in the wireless slice management interface is parsed in the case where the wireless slice management interface is not based on an NSMF entity to wireless NSSMF entity interface.
In step 220, data analysis is performed on the adjustment structure of the wireless sub-slice coverage area adopted by the control end, so as to obtain adjustment information of the wireless sub-slice coverage area.
In step 230, adjustment information of wireless sub-slice coverage is performed. For example, the wireless sub-slice adjustment instruction is executed, and the execution result of the wireless sub-slice adjustment instruction is fed back.
Fig. 2b illustrates a flow chart of further embodiments of a receiver adjustment method of a wireless slice of the present disclosure.
As shown in fig. 2b, in step 210b, it is determined whether the control end has a request for adjusting the coverage of the wireless sub-slice; if so, go to step 220b, otherwise, go to step 210b.
In step 220b, it is determined whether the wireless slice management interface is based on the NSMF-to-wireless NSSMF interface. If so, go to step 230b, otherwise, go to step 260b.
In step 230b, data parsing is performed on the wireless sub-slice coverage adjustment structure in Network Slice Instance Modification enhanced signaling for lifecycle management in NSMF entity to wireless NSSMF entity interface.
In step 240b, a wireless sub-slice adjustment instruction is executed.
In step 250b, the wireless sub-slice adjustment instruction execution result is fed back. After completion, the process goes to step 210b.
In step 260b, the wireless sub-slice coverage adjustment structure in the wireless slice management interface is parsed. After completion, the process goes to step 240b.
Fig. 3a illustrates a signaling diagram of some embodiments of a method of adjustment of wireless slices of the present disclosure.
As shown in fig. 3a, in the case that the wireless slice management interface adopts an NSMF entity to wireless NSSMF entity interface, the wireless slice adjustment method includes a wireless slice adjustment function control end and a wireless slice adjustment function receiving end.
The wireless slice adjustment function control end is located in an operation system (the operation system can be virtualized and comprises a plurality of slice functional entities or systems). The wireless slice adjusting function control end can be combined with NSMF or data information sharing, and the wireless slice adjusting function receiving end can be combined with NSSMF.
When there is a requirement for wireless slice coverage adjustment, the control end of the wireless slice adjustment function firstly prepares basic parameter information (including at least one of cell or base station unique identification, wireless slice identification information, PLMN, TAC, VLAN ID, 5QI, performance, guarantee, transmission and other slice related information) for wireless sub-slice coverage adjustment.
After the information preparation is completed, the data construction is carried out on the wireless sub-slice coverage adjustment structure in the Network Slice Instance Modification enhanced signaling of the lifecycle management in the interface from the NSMF entity to the wireless NSSMF entity.
In some embodiments, the enhancement structure needs to include SST, SD, corresponding to the TAC to which it belongs, cell/base station unique identification, adjustment type identification (addition or deletion), and other wireless slice related attributes. For example, SST and SD are primary KEYs, unique identifiers corresponding to the TAC, cell or base station to which they belong, and adjustment type identifiers (adding or deleting) are indispensable attributes, and other wireless slice correlation attributes are selected according to actual conditions.
An enhanced interface is invoked Network Slice Instance Modification to enhance signaling. And carrying out interface authentication on the interface from the NSMF entity to the wireless NSSMF entity.
After the interface authentication is completed, the wireless slice adjustment function control end transmits wireless sub-slice coverage adjustment information through Network Slice Instance Modification signaling enhancement interfaces from an NSMF entity to a wireless NSSMF entity interface.
The wireless slice adjustment function (i.e. the receiving end) may acquire (e.g. may transmit through NSSMF entity) the wireless sub-slice coverage adjustment structure, analyze and execute adjustment signaling, and finally feedback the result.
Fig. 3b shows a signaling diagram of further embodiments of the method of adjustment of wireless slices of the present disclosure.
As shown in fig. 3b, in the case that the wireless slice management interface does not use the NSMF entity to wireless NSSMF entity interface, the wireless slice adjustment method includes a wireless slice adjustment function control end and a wireless slice adjustment function receiving end.
The wireless slice adjustment function control end is located in an operation system (the operation system can be virtualized and comprises a plurality of slice functional entities or systems). The NSSMF entity can be deployed in an operating system or combined with OMC-R.
When the wireless slice adjustment function control end has the wireless slice coverage adjustment requirement, the wireless sub-slice coverage adjustment basic parameter information (at least one of cell or base station unique identification, wireless slice identification information, PLMN, TAC, VLAN ID, 5QI, performance, guarantee, transmission and other slice related information) is prepared, and data construction is carried out according to the cell-level slice management enhancement structure of the wireless slice management interface.
In some embodiments, the cell-level coverage adjustment structure is added at an update signaling interface in the wireless slice management interface. For example, the structure needs to include SST, SD, unique identification of the corresponding TAC, cell or base station to which it belongs, adjustment type identification (addition or deletion), and other wireless slice related attributes.
For example, SST and SD are primary KEYs, unique identifiers corresponding to the TAC, cell or base station to which they belong, and adjustment type identifiers (adding or deleting) are indispensable attributes, and other wireless slice correlation attributes are selected according to actual conditions.
In some embodiments, a cell-level slice adjustment interface signaling set is added in the TAC or taist level wireless slice management interface. For example, the number of cell-level slices in the signaling set is increased, the cell-level slices are deleted as the necessary signaling, and the cell-level slices are queried as the optional signaling.
For example, a cell-level slice adds or deletes signaling structures to host KEYs with cell or base station unique identities. The attributes include at least one of SST, SD, corresponding to the wireless slice related attributes such as TAC, PLMN, VLAN ID, etc.
For example, the cell-level slice query signaling uses the unique identification of a cell or a base station as a primary KEY, and the query result structure is consistent with the cell-level slice adding or deleting signaling structure.
By calling the corresponding management enhancement interface, the wireless slice adjusting function (i.e. the control end) performs wireless sub-slice coverage adjusting signaling, the wireless slice adjusting function (i.e. the receiving end) performs wireless sub-slice coverage adjusting structure analysis on the wireless slice management interface signaling, executes an adjusting instruction, and finally feeds back the result.
