Description

Configuration method of state feedback mode, state feedback method and device

Technical Field

The present disclosure relates to the field of communications, and in particular, to a method for configuring a status feedback manner, a status feedback method, and a device thereof.

Background

Under the prior art, a near real-time radio access network intelligent controller (near real time RAN intelligent controller, near-RT RIC) and a non-real-time radio access network intelligent controller (non-real-time RAN intelligent controller, non-RT RIC) are defined in an open radio access network (Open Radio Access Network, O-RAN) architecture; the connection between the two is called an A1 interface, and the A1 interface surrounds the addition, deletion, modification and search expansion of the A1 strategy.

At present, an O-RAN architecture seeks to realize optimal management and control of a mobile communication network by using an artificial intelligence method. Referring to fig. 1, in the O-RAN architecture, a service management and Orchestration unit (Service Management & organization, SMO) forms a unified network management platform that integrates a decentralized network element network management system. The SMO is connected to each network element via an O1 interface. The O1 interface is mainly responsible for extracting logs and reports, downloading and installing software and files, heartbeat monitoring, error detection control and the like; ensuring that managed entities can start smoothly, maintain stable working states, and timely obtain reports, logs, files, etc. for use as material for artificial intelligence (Artificial Intelligence, AI) and Machine Learning (ML) analysis.

Whereas the A1 interface is a special interface for practicing AI/ML management methods, mainly responsible for declaring the desire for future behavior of a particular object (called A1 policy). The A1 interface connects a non-RT RIC that is part of the SMO and a near-RT RIC that is part of the RAN. The A1 interface is standard and can mask differences between the manufacturer's internal SMO, non-RT RIC, near-RT RIC.

Specifically, the functions of the A1 interface are shown in table 1.

TABLE 1

Accordingly, the internal composition of the A1 strategy is shown in table 2.

TABLE 2

Inside the Near-RT RIC, the A1 endpoint (A1 termination) and the intelligent application (xAPP) are closely related to the A1 policy, A1 termination is the feed point of the A1 policy, and xAPP is the specific executor of the A1 policy.

For example, in the process of creating, upgrading and deleting an A1 policy, after the A1 termination receives a related instruction from the non-RT RIC, the corresponding xAPP is instructed to execute the add-delete-modify operation.

Under the prior art, an A1 policy execution state feedback procedure has been formulated for non-RT RIC to obtain the A1 policy execution state (executed, not yet executed, etc.), but the A1 policy execution state feedback procedure has not yet been formulated inside the near-RT RIC.

In view of the foregoing, there is a need to design a new feedback method configuration method and a corresponding feedback method for the execution state of the A1 policy, so as to overcome the above-mentioned drawbacks.

Detailed Description

In order to internally implement the state checking and feedback functions of the A1 policy, in the embodiment of the present disclosure, a flow, a message, and a cell for obtaining the execution state of the A1 policy inside the near-RT RIC are defined. Referring to fig. 2, a policy state feedback configuration entity is set inside the near-RT RIC, where the policy state feedback configuration entity may be an A1 termination or a management module, and the policy state feedback configuration entity may instruct any application inside the near-RT RIC to execute an A1 policy, and instruct the feedback execution state according to the instruction.

Preferred embodiments of the present disclosure are described in further detail below with reference to the accompanying drawings.

Referring to fig. 3, in an embodiment of the disclosure, a schematic flow of a feedback manner in which a policy state feedback configuration entity indicates a target application program to configure an A1 policy execution state is as follows:

step 300: the policy state feedback configuration entity sends a policy state feedback configuration message to the target application program, wherein the policy state feedback configuration message is used for indicating a feedback mode of the A1 policy execution state.

Specifically, the policy state feedback configuration entity may instruct the target application program to respond to the configuration result of the feedback mode of the A1 policy execution state in an explicit mode or an implicit mode.

Step 310: and the target application program responds to the strategy state feedback configuration result to the strategy state feedback configuration entity according to the indication of the strategy state feedback configuration message.

When the policy state feedback configuration entity indicates that the policy state feedback configuration result is responded in an explicit mode, the target application program can respond to the explicit policy state feedback configuration result by adopting the policy state feedback configuration response message;

when the policy state feedback configuration entity indicates the configuration of the feedback mode of the implicit mode feedback A1 policy execution state, the target application program may not respond to the explicit policy state feedback configuration result, and when the policy state feedback configuration entity does not receive the explicit policy state feedback configuration result, the policy state feedback configuration entity determines the content of the configuration result according to the agreed mode.

In practical applications, the policy state feedback configuration entity may be an A1 Termination, or may be another module inside the near-RT RIC, for example, a management module, in the subsequent embodiments, all use the A1 Termination as an example, but the policy state feedback configuration entity is also applicable to other modules, for example, a management module, and meanwhile, for convenience of description, any application program is used as a target application program, which is called xAPP and will not be described in detail.

Referring to fig. 4, in the embodiment of the disclosure, a schematic flow of a feedback manner in which the A1 Termination indicates that the target application configures the A1 policy execution state is as follows:

step 400: a1 termination sends an A1 POLICY STATUS REPORT configuration REQUEST message (policy_status_report_configuration_request) to the xAPP.

Specifically, when the POLICY STATUS feedback configuration entity is A1 termination, the POLICY STATUS feedback configuration message described in step 300 is referred to as policy_status_report_configuration_request.

Step 410: xAPP returns an A1 POLICY STATUS REPORT configuration RESULT message (policy_STATUS_REPORT_CONFIG_RESULT) to A1 termination.

Specifically, when the POLICY STATUS feedback configuration entity is A1 termination, the POLICY STATUS feedback configuration message described in step 310 is referred to as policy_status_report_configuration_result.

xAPP responds to the strategy state feedback configuration RESULT to A1termination through policy_STATUS_REPORT_CONFIG_RESULT, namely, the feedback mode of reporting the A1 strategy execution state to A1termination is configured or not configured.

Alternatively, the definition of each cell carried in the policy_status_report_configuration_request and policy_status_report_configuration_result is shown in table 3.

The policy_status_report_configuration_request carries at least a POLICY identifier (POLICY ID) and a POLICY STATUS REPORT type (Policy Status Report Type), and further may also carry a reporting Period (REPORT Period) and a POLICY STATUS REPORT configuration response mode (Policy Status Report Config ACK Type).

The policy_status_report_configuration_result carries at least a Response Code and a Description (Response Code & Description), and further, may also carry a reason for the unsuccessful (Error in) and a minimum back-off Time (Wait Time) before the next request.

TABLE 3 Table 3

A specific example of Response Code & Description may be 200OK, i.e. indicate that the configuration was successful (Success); 404, indicating a configuration failure (failure) because the policy ID does not exist (policy ID not found); it may also be 503, indicating that the process is slow (pending) because the service is not available (service unavailable).

A specific example of Error inoint may be CPU overload (CPU hot busy).

On the other hand, depending on the reception of Policy Status Report Config ACK Type in the policy_status_report_configuration_request, the xAPP may choose to reply or not reply to the policy_status_report_configuration_result.

For example, if the A1 termination indicates the xAPP, after the feedback manner of the A1 POLICY execution state has been configured correctly, no message is replied, and if the A1 termination does not receive the policy_status_report_config_request returned by the xAPP, the feedback manner of the A1 POLICY execution state is considered as a POLICY state feedback configuration result that the xAPP response has been obtained, that is, the feedback manner of the A1 POLICY execution state has been configured correctly.

Based on the above embodiments, further, the A1 termination and the xAPP may encapsulate the cells carried in the policy_status_report_request and the policy_status_report_report_result_result in any one of the following manners, namely, the respective information elements in table 3:

1) And packaging by adopting an interface-based interaction mode.

2) Encapsulation is performed in an interactive manner based on (operation+object of operation) op+object.

In the embodiment of the disclosure, object is an operation Object of an A1 policy, and OP represents a specific operation performed on the operation Object; where op=update, represents the incremental configuration to obtain information of particular interest to the relevant Object.

In the case of encapsulation according to mode 2), the cells in table 3 can be recorded as in table 4:

TABLE 4 Table 4

3) And packaging by adopting an interaction mode based on function call.

Based on the above embodiment, further, the policy state feedback configuration message mentioned in step 300 may be other messages interacted between A1 termination and xAPP, for example, add cells such as Policy Status Report Type, report Period, etc. in an A1 policy new request message or an A1 policy upgrade request message; accordingly, the policy state feedback configuration response message mentioned in step 310 may also be other messages interacted between A1 termination and xAPP, for example, add cells such as Wait Time in an A1 policy update response message or an A1 policy upgrade response message.

In this case, the methods and rules executed for policy_status_report_configuration_request in the above embodiment are applicable to the A1 POLICY new REQUEST message or the A1 POLICY update REQUEST message, and the methods and rules executed for policy_status_report_configuration_result in the above embodiment are applicable to the A1 POLICY new response message or the A1 POLICY update response message, which are not described herein.

Based on the above embodiment, further, the policy status feedback configuration entity may also be other modules in the near-RT RIC, such as a management module; then, the policy state feedback configuration message mentioned in step 300 may also be various messages adopted by the management module, for example, add cells such as Policy Status Report Type and Report Period into the module management message; accordingly, the policy state feedback configuration response message mentioned in step 310 may also be various messages adopted by the management module, for example, in the module management response message, add cells such as Wait Time.

In this case, the methods and rules executed for policy_status_report_configuration_request in the above embodiments are applicable to the module management message, and the methods and rules executed for policy_status_report_configuration_result in the above embodiments are applicable to the module management response message, which is not described herein.

Based on the above embodiments, referring to fig. 5, in the embodiment of the disclosure, a schematic flow of the target application program feeding back the A1 policy execution state to the policy state feedback configuration entity is as follows:

Step 500: the target application program sends a policy state message to a policy state feedback configuration entity, wherein the policy state message carries an A1 policy execution state, and the policy state message is sent by the target application program according to the instruction of the policy state feedback configuration message.

Specifically, the feedback manner of the A1 policy execution state indicated by the policy state feedback configuration message may include a reported trigger condition, for example, a set period is reached, a state change event occurs, an immediate report of the occurred state event is required, etc., where when the target application program meets the trigger condition, the A1 policy execution state is reported to the A1 policy state feedback configuration entity.

Further, the target application program may instruct the policy state feedback configuration entity to feedback the receiving result of the policy state message in an explicit manner or an implicit manner.

Step 510: the policy state feedback configuration entity responds to the target application program to the receiving result of the policy state message based on the indication of the policy state message.

When the target application program indicates to answer the receiving result of the strategy state information in an explicit mode, the strategy state feedback configuration entity can answer the explicit receiving result to the target application program by adopting the strategy state response information;

When the target application program indicates that the receiving result of the policy state message is responded in an implicit mode, the policy state feedback configuration entity can not respond to the explicit receiving result, and when the target application program does not receive the explicit receiving result, the target application program judges the content of the receiving result according to a stipulated mode.

Similarly, in practical application, the policy state feedback configuration entity may be an A1termination, or may be another module inside the near-RT RIC, for example, a management module, in the subsequent embodiment, all use the A1termination as an example, but the policy state feedback configuration entity is also applicable to other modules, for example, a management module, and meanwhile, for convenience of description, any application is referred to as an xAPP as a target application, which will not be described again.

Referring to fig. 6, in the embodiment of the disclosure, a schematic flow of feeding the state of executing the A1 policy back to the A1termination by the xAPP is as follows:

step 600: xAPP sends an A1 POLICY STATUS REPORT message (policy_STATUS_REPORT) to A1 termination.

Specifically, when the POLICY STATUS feedback configuration entity is A1termination, the POLICY STATUS message described in step 500 is referred to as policy_status_report.

Step 610: the xAPP returns an A1 POLICY STATUS REPORT response message (policy_STATUS_REPORT_ACK) to the A1 termination.

Specifically, when the POLICY STATUS feedback configuration entity is A1 termination, the POLICY STATUS response message described in step 510 refers to policy_status_report_ack.

xAPP REPORTs the A1 POLICY execution STATUS to A1 termination through policy_STATUS_REPORT_ACK, i.e. REPORTs to A1 termination whether the A1 POLICY has been executed correctly.

Alternatively, the definition of each cell carried in the policy_status_report and policy_status_report_ack is shown in table 5.

TABLE 5

A specific example of Response Code & Description may be 200, i.e. indicating receipt and correct parsing (Success); 401 may be indicative of a failure to execute (failure) because the parameter is invalid (invalid parameter).

Specific examples of Error inoint may be unknown policy ID (unknown policy ID), invalid A1 policy enforcement state (invalid policy status).

The cell Policy Status Report ACK Type in the policy_status_report is configured to notify A1 termination, and reply or not reply to the xAPP with explicit or implicit means.

On the other hand, according to the receiving situation of Policy Status Report ACK Type in policy_status_report, A1 termination may choose to reply or not reply to policy_status_report_ack.

For example, if the xAPP indicates A1 termination, and after the A1 POLICY execution state has been correctly received, no message is replied, then if the xAPP does not receive the policy_STATUS_REPORT_ACK returned by A1 termination, it is considered that the A1 POLICY execution state has been correctly received as a result of the receipt of the A1 POLICY execution state for which the A1 termination response has been obtained.

Based on the above embodiment, further, the A1 termination and the xAPP may encapsulate each cell carried in the policy_status_report and the policy_status_report_ack in any one of the following manners, namely, each information element in table 5:

1) And packaging by adopting an interface-based interaction mode.

2) The encapsulation is performed in an interactive mode based on OP+object.

3) And packaging by adopting an interaction mode based on function call.

Based on the above embodiment, further, the policy status feedback configuration entity may also be other modules in the near-RT RIC, such as a management module; then, the Policy Status message mentioned in step 500 may be various messages adopted by the management module, and only relevant cells such as Policy Status and Policy Status Report ACK Type need to be added; accordingly, the policy status Response message mentioned in step 510 may be various messages adopted by the management module, and only relevant cells such as Response Code and Description need to be added.

In this case, the methods and rules executed for policy_status_report in the above embodiments are applicable to the corresponding messages adopted by the management module, and the methods and rules executed for policy_status_report_ack in the above embodiments are applicable to the corresponding messages adopted by the management module, and are not described herein.

step 701: the non-RT RIC indicates A1 termination to report the A1 policy enforcement status.

Specifically, the non-RT RIC will send the policy identification (policy ID) of the A1 policy to be queried to A1 termination.

Step 702: a1 the termination is performed to check the validity of the policy identifier (policy ID), and if invalid, step 703 is performed; if so, steps 704-709 are performed.

Step 703: a1 termination returns 404 to the non-RT RIC indicating that the corresponding A1 policy is not matched.

Step 704: a1 termination determines that configuration xAPP immediately reports the A1 policy enforcement state.

Step 705: a1 termination sends a policy_status_report_configuration_request to the xAPP.

Step 803: the non-RT RIC indicates A1 termination to report the A1 policy enforcement status.

Step 804: a1 the termination is performed to check the validity of the policy identifier (policy ID), and if invalid, step 803 is performed; if so, steps 806-809 are performed.

Step 805: a1 termination returns 404 to the non-RT RIC indicating that the corresponding A1 policy is not matched.

Step 806: a1 termination determines that xAPP periodic report A1 policy enforcement status is configured and decides to wait for the next report to come.

Step 807: xAPP sends policy_status_report to A1 termination.

Step 808: a1 termination sends corresponding response codes and other necessary cells to the non-RT RIC based on the obtained A1 policy enforcement status.

503, slow process treatment;

404, the process fails.

Step 809: a1 termination sends or does not send policy_status_report_ack to the xAPP.

Specifically, A1 termination needs to refer to the reception in step 807 of Policy Status Report ACK Type, and transmit or not transmit policy_status_report_ack to the xAPP.

Optionally, there is no strict timing relationship between step 808 and step 809.

Scene III: the near-RT RIC actively reports the A1 policy execution status to the non-RT RIC, as shown in FIG. 9, and the specific execution process is as follows:

step 901: a1 termination configures a feedback mode of an execution state of an A1 strategy adopted by xAPP.

Specifically, the feedback mode of the execution state of the A1 policy adopted by the xAPP may be configured according to a default configuration, a management configuration, an operation and maintenance configuration, an explicit mode requirement or an implicit mode requirement of the non-RT RIC, etc., for example, the feedback mode is configured to be periodic, disposable or other modes, etc.

Step 902: a1 termination sends a policy_status_report_configuration_request to the xAPP.

Specifically, A1 termination may be set Policy Status Report Config ACK Type.

Step 903: xAPP sends or does not send policy_status_report_configuration_result to A1 termination.

Specifically, the xAPP needs to refer to the receiving situation of Policy Status Report Config ACK Type in step 902, and send or not send policy_status_report_configuration_result to the A1 termination.

Step 904: xAPP sends policy_status_report to A1 termination.

Step 905: a1 termination reports the A1 policy enforcement status to the non-RT RIC.

Step 906: a1 termination sends or does not send policy_status_report_ack to the xAPP.

Specifically, A1 termination needs to refer to the acquisition of Policy Status Report ACK Type in step 904, and send or not send policy_status_report_ack to the xAPP.

Optionally, there is no strict timing relationship between step 905 and step 906.

Step 907: the non-RT RIC returns a response message to A1 termination.

Specifically, the non-RT RIC returns 204 to the A1 termination, and does not carry other information content, informing the A1 termination that the reported A1 policy enforcement state has been successfully obtained.

In practical application, the xAPP may also autonomously report the A1 policy execution state that it is responsible for, and may, but is not limited to, adopt a periodic feedback manner, a feedback manner triggered by state change, and so on.
