Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture to which an embodiment of the present invention is applicable, as shown in fig. 1, including: SMO, near-RT RIC, open centralized control plane (Open Centralized Unit Control Plane, O-CU CP), open centralized control plane (Open Centralized Unit User Plane, O-CU UP), open distributed units (Open Distributed Unit, O-DU), and Open Radio units (O-RU). Wherein the SMO may communicate with the near-RT RIC via an SMO A1 Interface (SMO A1 Interface), and the SMO may also communicate with the near-RT RIC via an SMO 1Interface (SMO O1 Interface), and the SMO may also communicate with other units (e.g., O-CU CP, O-CU UP, O-DU, and O-RU) via SMO 1 interfaces, and the near-RT RIC may communicate with the O-CU CP, O-UP, and O-DU units via a near-RT RIC E2 Interface (near-RT RIC E2 Interface).

It should be noted that the above network architecture is only an example schematic diagram, for example: units may be added or subtracted from the above architecture, or interfaces may be added, or interface names may be modified, which is not limited in this embodiment of the present invention.

Referring to fig. 2, fig. 2 is a flowchart of an information processing method according to an embodiment of the present invention, where the method is applied to a near real-time radio access network controller, as shown in fig. 2, and includes the following steps:

201. receiving information sent by the SMO through a first interface, wherein the information comprises at least one of a policy and a management instruction;

202. performing at least one of the following for the information:

The first interface may be one or more interfaces, for example: an A1 interface and an O1 interface as shown in fig. 1. In addition, the policy and management instructions may be received through different interfaces. In addition, receiving the policy may be receiving content or an identification of the policy, or the like.

In the embodiment of the present invention, the policy may be any policy sent by the SMO to the near-real-time radio access network controller, for example, a policy responsible for declaring a future performance of a first object, which may be referred to as an A1 policy, where the first object may be one or more specific objects in the near-real-time radio access network controller, or may be one or more network nodes, for example, at least one of a Centralized Unit (CU), a Distributed Unit (DU), an evolved Node B (eNB), and the like. And the management instruction may be any management instruction sent by the SMO to the near real time radio access network controller, such as a management instruction for indicating a management target of the near real time radio access network controller.

The selecting, by the plurality of APPs in the near-real-time radio access network controller, an APP that executes the policy may be selecting, among the plurality of APPs, an APP that matches the policy. By selecting the APP for executing the policy, the flexibility for executing the policy, the reliability for executing the policy and the like can be improved, so that the processing performance of the near-real-time radio access network controller can be improved.

The managing operation may be performed with respect to the near-real-time radio access network controller or one or more modules in the near-real-time radio access network controller. The management operation can strengthen the near-real-time wireless access network controller so as to improve the processing performance of the near-real-time wireless access network controller.

In the embodiment of the invention, the processing performance of the near-RT RIC can be improved through the steps, and the network performance of the O-RAN architecture is further improved.

As an alternative embodiment, the near-RT RIC may include, as shown in fig. 3:

a near-RT RIC Platform part (nRRP) and a near-RT RIC Core part (nRRC), where nRRC is the main body and Core implemented by the O-RAN architecture, and nRRP constitutes the background and support system for normal operation of nRRC, such as an operating system, a database, a local manager, an external device, etc.

Further, nrcr includes: the system comprises a near-RT RIC A1 Interface (near-RT RIC A1 Interface), a near-RT RIC O1 Interface (near-RT RIC O1 Interface), a near-RT RIC E2 Interface (near-RT RIC E2 Interface), an xAPP Selector (xAPP Selector), a near-RT RIC service Coordinator (near-RT RIC Service Coordinator, nRRS connector), an O1 management object instance Controller (O1 Management Object Instance Controller, O1 MOI Controller), a Database Adapter (Database Adapter) and other modules.

In addition, the near-RT RIC A1 Interface, near-RT RIC O1 Interface, near-RT RIC E2 Interface may be a standardized A1, O1, E2 Interface in an O-RAN architecture.

While the xAPP Selector module may make decisions on the specific executives of the policies sent by the SMO (e.g., the A1 policy), such as: after the A1 strategy is fed in by the near-RT RIC A1 Interface, the xAPP Selector module selects a proper xAPP according to the working state, the operation preference, the load condition and the like of each xAPP, and instructs the xAPP to install the related strategy.

The xAPP may control the behavior of the E2 node, referred to as E2 subscription, or decide subscription information according to the behavior and/or condition of the E2 node. For example: the xAPP decides subscription information according to the feed-in A1 strategy of the xAPP Selector module and the opened function of the E2 node. Further, the xAPP can then make further action decisions, called CONTROL instructions, based on the REPORT, INSERT, POLICY feedback (indication report) of the E2 node. Wherein, this partial function is realized by nRRS coordinators. Wherein, the xAPP can be any APP.

Wherein, the E2 node may include: at least one of a Centralized Unit (CU), a Distributed Unit (DU), an evolved Node B (eNB), and the like.

And the REPORT refers to: after a specific event occurs, the E2 node reports the event. Wherein the local processing of the E2 node is not affected by the REPORT operation.

INSERT refers to: after a specific event occurs, the E2 node reports the event. The E2 node pauses local processing, and when the near-RT RIC replies, the subsequent operation is executed according to the instruction of the reply; when no near-RT RIC reply is obtained, the continuing or aborting operation is performed according to a predetermined configuration.

CONTROL means: after the near-RT RIC recognizes a specific event, the E2 node is instructed to initiate a procedure or resume a procedure.

POLICY refers to: a policy is predetermined to be configured by which subsequent operations are performed upon the occurrence of a particular event.

The O1 MOI Controller can realize the concentration of the decomposition, the issuing, the report collection and the like of the O1 management instruction.

Further, the database stores software, logs, records, configuration tables, etc. files that may be an important component of the normal operation of the near-RT RIC. In addition, in practical application, the professional Database has strong capability, but the implementation mode may have larger difference, so the Database Adapter module can shield the difference of the Database, and provides convenience for the development and maintenance of other near-RT RIC modules. For example, the Database Adapter provides a unified authorization call application program interface (Application Programming Interface, API) to the outside, and finishes the operations of inquiring, adding, deleting and modifying the authorization data.

It should be noted that the structure of the near-RT RIC shown in FIG. 3 is only an example, for example: some of the modules in the above-described structure may be combined, or one module may be further divided into a plurality of modules, and functions of the respective modules may be expanded, or reduced, or functions between the modules may be interchanged, or the like. In addition, the above modules may be functional modules, such as: the virtual module may be a hardware module, or a part of the virtual module and a part of the hardware module.

As an optional implementation manner, in the case that the first interface includes an A1 interface, the information includes the policy.

Among these, the above strategy may be referred to as the A1 strategy.

As an alternative embodiment, the selecting, by the multiple APPs in the near real-time radio access network controller, the APP that performs the policy includes:

Wherein the attribute information may include at least one of:

function, work history performance, load status, set preferences.

In this embodiment, the policy may be executed by selecting an APP matching the policy or selecting an APP having better performance according to the attribute information of the APP.

Further, the selection may be implemented by an xAPP Selector shown in FIG. 3, for example:

the xAPP Selector selects APP by the following formula:

P＝a1·X1+a2·X2+a3·X3

wherein P represents xAPP selection probability, X1 represents xAPP duration performance, and a1 represents the weight; x2 represents an xAPP load state, and a2 represents the weight of the item; x3 represents the operator's set preferences and a3 represents the weight. X1, X2, X3, a1, a2, a3 take values of 0,1, and a1+a2+a3=1. Obviously, the factors affecting P may be more than the three listed above, nor is the expression expressing the selection probability necessarily as listed above, that is, the above formula is merely an example, for example: other attribute information may also be added, such as functionality, or some attribute information may be reduced, etc.

Furthermore, the appropriate APP can be selected by the target of the strategy and the attribute information of each APP.

In addition, in the embodiment of the present invention, selecting APP is not limited to being implemented by the xAPP Selector shown in fig. 3, for example: it is also possible that this is performed by other modules of the near real time radio access network controller.

Two types of results exist in the selection, one type of APP is selected, and the other type of APP is not selected. In addition, SMO sending a policy may refer to installing the policy, updating the policy, or deleting the policy.

instruct the first APP to install the policy;

wherein, first APP is one or more APP.

In this embodiment, as shown in fig. 4:

step 1, a near-RT RIC reports an A1 strategy to an xAPP Selector;

step 2, selecting a proper xAPP according to the A1 strategy target, the xAPP function, the xAPP work history expression, the xAPP load state, the setting preference of an operator and the like.

Step 3, the xAPP Selector sends an A1 policy installation instruction to the selected xAPP

And 4, the xAPP completes the installation and returns a confirmation to the xAPP Selector.

Step 5, xAPP Select reports to near-RT RIC A1 Interface that A1 policy has been installed.

Of course, the above-described FIG. 4 is merely exemplary, such as: in the steps 3 to 4, after the xAPP possibly receives the A1 policy installation instruction, the xAPP returns without the installation being completed. In addition, in steps 3-4, the xAPP Selector may issue the same A1 policy installation instruction to more than one xAPP, i.e., may issue the same policy to multiple APPs.

Optionally, the method further comprises:

The first APP may have an APP that is installed with the policy successfully, and may send a first report to the SMO only if the first APP has an APP that is installed with the policy successfully.

For example: the xAPP Selector sends A1 policy installation instructions to a plurality of xAPP, and the xAPP Selector reports that the A1 policy installation is successful to the near-RT RIC A1 Interface as long as one xAPP replies that the A1 policy installation is successful. Further, the xAPP with installation failure can be recorded in a table for subsequent analysis.

Optionally, the method further comprises:

Wherein the first APP is an APP with the policy installed, and the network node may be the E2 node described above, or other nodes in communication with the near-RT RIC.

The subscription information of the network node according to the policy may be corresponding subscription information, such as event reporting, log reporting, action execution, flow operation, etc., determined according to the desire, action, etc. indicated by the policy. Furthermore, the corresponding subscription information can be determined by combining the attributes such as the state, the state and the like of the network node so as to achieve the landing realization of the policy.

In this embodiment, the first APP decides the subscription information of the network node according to the policy, so that the management performance of the near-RT RIC may be improved.

Optionally, the method further comprises:

The second report can enable SMO to learn about the reason of the failure to install, so as to facilitate SMO optimizing policy or take other measures to further improve the network performance of the O-RAN architecture.

For example: as shown in fig. 5:

step 1, a near-RT RIC reports an A1 strategy to an xAPP Selector;

step 2, the xAPP Selector cannot select a proper xAPP according to the A1 policy target, xAPP functions, xAPP work history performance, xAPP load status, setting preference of an operator and the like. If all xAPP is overloaded or xAPP which is not in accordance with the function is possible, etc.;

step 3, the xAPP Selector reports to the near-RT RIC A1 Interface that the A1 strategy cannot be installed, and the reason that the strategy cannot be installed is carried over.

Also for example: as shown in fig. 6:

Step 1, a near-RT RIC reports an A1 strategy to an xAPP Selector;

step 2, selecting a proper xAPP according to an A1 strategy target, xAPP functions, xAPP work history expression, xAPP load states, setting preferences of operators and the like;

step 3-4, the xAPP Selector sends an A1 strategy installation instruction to the selected xAPP, but the xAPP replies that the installation is impossible, and the reason that the installation is impossible is carried out at the same time;

step 5, the xAPP Selector reports to the near-RT RIC A1 Interface that the A1 strategy cannot be installed, and the reason that the strategy cannot be installed is carried over.

instruct the second APP to update the policy;

wherein the second APP is one or more APPs that have installed the policy.

For example: fig. 7 shows:

step 1, a near-RT RIC submits an updated A1 strategy to an xAPP Selector;

step 2, xAPP queries the record list of the installed A1 strategy, and identifies the destination party updated by the A1 strategy, namely the second APP;

step 3-4, the xAPP Selector sends an A1 strategy updating instruction to the selected xAPP, and the xAPP completes updating and confirms;

step 5, xAPP Selector reports to near-RT RIC A1 Interface that A1 policy has been updated.

Optionally, the method further comprises:

In the embodiment, the strategy of updating failure can be deleted in time, so that errors caused by using the strategy of updating failure by the APP can be avoided.

For example: as shown in fig. 8:

step 1, a near-RT RIC submits an updated A1 strategy to an xAPP Selector;

and 2, the xAPP queries the installed A1 strategy record table, and identifies the destination party updated by the A1 strategy, namely the second APP.

Step 3-4, the xAPP Selector sends an A1 strategy updating instruction to the selected xAPP, and the xAPP replies that the updating cannot be performed and the reason that the updating cannot be performed is carried out at the same time;

step 5, the xAPP Selector reports the failure of updating the A1 strategy to the near-RT RIC A1Interface, and the reasons that the strategy cannot be updated are carried over;

and 6, interacting the xAPP Selector with the xAPP, and deleting the A1 strategy with unsuccessful updating.

The timing relationships of step 5 and step 6 are not limited, and they may be concurrent or the former may be subsequent.

Further, the xAPP Selector may issue an A1 policy update instruction to a plurality of xAPP, and as long as there is one xAPP that replies that the A1 policy update is successful, the xAPP Selector reports that the A1 policy update is successful to the near-RT RIC A1 Interface. Otherwise, the xAPP Selector should report an A1 policy update failure to the near-RT RIC A1Interface, while instructing an unsuccessful update xAPP to delete the relevant A1 policy. In addition, the xAPP with failed update can be recorded in a table for subsequent analysis.

instruct the third APP to delete the policy;

wherein the third APP is one or more APPs that have installed the policy.

In this embodiment, a policy of deleting the APP installation in time may be implemented.

For example: as shown in fig. 9:

step 1, a near-RT RIC reports the deleted A1 strategy to an xAPP Selector;

and 2, the xAPP queries the installed A1 strategy record table, and identifies the destination party deleted by the A1 strategy, namely the third APP.

And 3-4, sending an A1 strategy deleting instruction to the selected xAPP by the xAPP Selector, and completing deleting and confirming the xAPP.

Step 5, xAPP Selector reports to near-RT RIC A1 Interface that A1 policy has been deleted.

The time sequence relationships of the steps 3-4 and the step 5 are not limited, and they may be concurrent or the former and the latter may be concurrent.

As an optional implementation manner, in the case that the first interface includes an O1 interface, the information includes the management instruction, where the management instruction is used to indicate a management target of the near real-time radio access network controller.

The management target may be that the O1 management instruction indicates a management target that should be implemented by the near-RT RIC, but does not indicate a specific bearing module of the management instruction.

In this embodiment, the management purpose of the near-real-time radio access network controller indicated by the SOM may be achieved to increase the management performance of the O-RAN architecture, so as to further improve the network performance of the O-RAN architecture.

In this embodiment, the management object instance controller may be a management object instance controller in a near real-time radio access network controller as shown in fig. 3, and of course, in this embodiment, it is not limited to be implemented by the near real-time radio access network controller shown in fig. 3, for example: may be implemented by other near real-time radio access network controllers including management object instance controllers, without limitation.

In this embodiment, since the management operations described above are uniformly performed by the management object instance controller, the management performance of the near-real-time radio access network controller can be improved.

Optionally, the heartbeat diagnosis includes at least one of:

A management object instance (Management Object Instance, MOI) of the near real-time radio access network controller is instructed to report a heartbeat to the management object instance controller.

The step of reporting the heartbeat of the near-real-time wireless access network controller through the O1 interface may be reporting the heartbeat of the near-real-time wireless access network controller to the SMO, so that the SMO can know the heartbeat of the near-real-time wireless access network controller in time, so as to facilitate management of the near-real-time wireless access network controller by the SMO.

For example: and configuring a special heartbeat detection process for the O1 interface, and configuring a near-RT RIC through the interface to report heartbeats at fixed time or detecting the using state of the near-RT RIC at any time by the SMO. Wherein the O1 MOI Controller can directly respond to the process as a proxy for near-RT RIC.

The near-RT RIC can be configured to report heartbeat at fixed time by configuring the O1 MOI Controller, the active state of each module can be detected at any time, and the equipment state of the near-RT RIC can be accurately reported.

For example: as shown in fig. 10:

step 1, near-RT RIC O1 Interface requires O1 MOI Controller to report heartbeat immediately;

step 2, O1 MOI Controller reports heartbeat to near-RT RIC O1 Interface.

Also for example: as shown in fig. 11:

Step 1, a near-RT RIC O1 Interface configuration O1 MOI Controller reports heartbeat;

and 2-4, continuously reporting the heartbeat to the near-RT RIC O1 Interface by the O1 MOI Controller according to the configuration requirement.

Also for example: as shown in fig. 12:

step 1, an O1 MOI Controller requests the MOI to immediately report the heartbeat;

step 2, the MOI reports the heartbeat to the O1 MOI Controller.

Also for example: as shown in fig. 13:

step 1, an O1 MOI Controller configures MOI to report heartbeat;

and 2-4, continuously reporting the heartbeat to an O1 MOI Controller by the MOI according to the configuration requirement.

Alternatively, the registration may be a generation and maintenance module registry. The module registry records the module name, input, output, internal processing intermediate results, etc., and can facilitate the decomposition process of the MOI, where an example is shown in table 1:

TABLE 1

Optionally, the registering includes: and indicating the management object instance of the near real-time radio access network controller to report a registration request to the management object instance controller, wherein the registration request comprises at least one of module input, module output and intermediate processing results.

In this embodiment, the module can be known in time by registration.

For example: as shown in fig. 14:

step 1, MOI reports a registration request to an O1 MOI Controller, wherein the registration request comprises information such as module input, output, intermediate processing results and the like;

step 2, the O1 MOI Controller receives the registration request of the MOI and distributes internal identification for the MOI.

Optionally, the Module In Charge (MIC) identifying includes: decomposing, by the management object instance controller, a management objective of the near real-time radio access network controller into executable tasks, identifying corresponding responsibility modules, and instructing at least one or a group of responsibility modules to provide output and/or perform objective actions.

The decomposing, by the management object instance controller, the management target of the near-real-time radio access network controller into executable tasks may be decomposing, by the management object instance controller, the management target of the near-real-time radio access network controller into executable tasks according to the management object instance target and the module registry. Of course, the management object instance may also be decomposed into executable tasks based on the management object instance targets and module registry, with instructions providing corresponding outputs or corresponding actions to one or a group of responsible modules.

One may for example be as follows:

step 1: selecting xAPP1 (O1MOI1=when HO decision, refer xAPP 1) when O1 MOI1 is equal to HO decision;

step 2: reading the register table to find mic=xapp Selector (read Register Table and find out MIC =xapp Selector);

step3: o1 MOI Controller commands xAPP selector, xAPP1 selection factor=0.95 (O1 MOI Controller command xAPP Selector, xAPP1 selected factor=0.95).

Also for example: as shown in fig. 15:
