(1) Open-radio access network (O-RAN)

The O-RAN is a technology for realizing more intelligent and open access network management by modularizing and standardizing software in the access network device and the access network device.

The O-RAN is a new technology for re-integrating and determining technologies such as C-RAN, xRAN and M-CORD in the related art, and has the characteristics of open source software, white-box hardware, open interfaces and the like. The O-RAN divides the wireless system equipment into standard subsystem components, and can support hardware independent decoupling of a hardware accelerator, a general hardware platform and a Remote Radio Unit (RRU) subsystem through layered independent research and development.

Fig. 1 is a schematic structural diagram of an O-RAN10 provided in the present application. Among them, the O-RAN10 includes a service management organization frame 101(service management and organization frame), an infrastructure management frame 102(infrastructure management frame), an infrastructure 103, a Near real-time infinite intelligent controller 104(Near real-time radio interactive controller, Near RT RIC), an open center unit control plane 105 (open-center unit-control plane, O-CU-CP), an open center unit user plane 106 (open-center unit-user plane, O-CU-UP), an open distributed unit 107(open-distributed unit, O-DU), and an open-radio unit 108 (O-RU). The service management orchestration framework 101 includes a Non real-time radio interactive controller 1011(Non RT RIC).

Wherein the Non RT RIC1011 is in communication connection with the Near RT RIC104 through an A1 interface, and the Near RT RIC104 is in communication connection with the O-CU-CP105, the O-CU-UP106 and the O-DU107 respectively through an E2 interface. The O-CU-CP is communicatively coupled to the O-CU-UP via an E1 interface.

The Non RT RIC1011 and the Near RT RIC104 are used for intelligently managing O-RAN wireless network information. For example, the traffic flow data of the O-RAN10 is monitored and analyzed to obtain the wireless network status and the network characteristics of the terminal.

The O-RAN is based on a general server's baseband processing unit, which can open up to the MEC capability to better support MEC services. For example, by introducing big data and artificial intelligence computing on a wireless cloud infrastructure, business requirements can be predicted more accurately.

(2) Mobile Edge Computing (MEC)

MEC is a communication architecture protocol proposed by the European Telecommunications Standards Institute (ETSI).

Mobile edge computing, also known as multi-access edge computing (MEC), refers to a method for providing required service resources to a terminal device by a communication node by placing a device with computing capabilities at a node of the communication network. Therefore, the terminal obtains the required service resources through the MEC equipment arranged at the network node, and the service delay of the terminal equipment is reduced.

Fig. 2 is a schematic structural diagram of an MEC system 20 according to the present disclosure. The MEC system 20 includes a MEC platform 201 (MEP) and at least one MEC application 202.

As a possible embodiment of the present application, referring to fig. 4, as shown in fig. 5, a flowchart of an O-RAN capability opening method provided in an embodiment of the present application is shown.

In case 1, when the first request message is used to request the first entity to send the wireless network information to the MEC application, the scheme specifically includes the following two cases, that is, case 1.1 and case 1.2:

case 1.1, the first request message is a wireless network information query request message.

S501, the first entity sends a wireless network information inquiry request message to the O-RAN according to the first request message. Correspondingly, the O-RAN receives a wireless network information inquiry request message sent by the first entity.

For example, the first entity may specifically send a wireless network information query request message to the capability openness proxy module in the O-RAN, and correspondingly, the capability openness proxy module in the O-RAN receives the wireless network information query request message sent by the first entity.

In one possible implementation, the wireless network information query request includes an identification of the wireless network information.

S502, the O-RAN sends a wireless network information inquiry response message to the first entity. Correspondingly, the first entity receives a wireless network information inquiry response message sent by the O-RAN.

S503, the first entity sends wireless network information to the MEC application. Accordingly, the MEC application receives the wireless network information sent by the first entity.

Through the scheme, the first entity can acquire the wireless network information required by the MEC application from the O-RAN according to the first request message and send the wireless network information to the MEC application, so that the opening of the wireless capability of the O-RAN is realized.

Case 1.2, the first request message is used to instruct the first entity to create a wireless network information event.

S504, the first entity creates a wireless network information event according to the first request message.

The wireless network information event is an event which triggers the first entity to send the wireless network information to the MEC application.

In one possible implementation, the wireless network event includes a trigger condition for sending wireless network information.

Illustratively, the trigger condition may be a change in the wireless network information. The triggering condition may also be a timer trigger that triggers the wireless network event after the timer expires.

When the wireless network information event is satisfied, the first entity may perform step S505.

And S505, the first entity sends wireless network information to the MEC application.

It is noted that the O-RAN may be in network communication with the first entity through an API interface of the first entity.

In one possible implementation, the O-RAN may send the wireless network information to the first entity in real-time.

In another possible implementation, the first entity may request the radio network information required by the MEC application from the O-RAN when the radio network event is satisfied, and the O-RAN sends the radio network information to the first entity.

Case 2, in the case that the first request message is used to request the first entity to instruct the O-RAN to update the configuration parameters, the scheme specifically includes the following two cases, case 2.1 and case 2.2:

case 2.1, the first request message is a configuration parameter update indication message.

S506, the first entity sends a configuration parameter updating indication message to the O-RAN according to the first request message. Accordingly, the O-RAN receives a configuration parameter update indication message sent by the first entity.

Wherein the configuration parameter update indication message includes the configuration parameters that the O-RAN needs to update.

Illustratively, the configuration parameters include network load, transmission data bandwidth, traffic delay, etc. of the O-RAN.

S507, the O-RAN sends a configuration parameter update response message to the first entity. Correspondingly, the first entity receives the configuration parameter updating response message sent by the O-RAN.

Wherein the configuration parameter update response message comprises the configuration parameter update result of the O-RAN.

It should be noted that, after the O-RAN updates the configuration parameters according to the configuration parameter update indication message, a configuration parameter update response message including an updated configuration update result may also be sent to the first entity.

In a possible implementation manner, the configuration parameter update result includes the updated configuration parameter information of the O-RAN. The configuration parameter update result may further include update success or update failure.

For example, if the O-RAN cannot update the configuration parameters according to the configuration parameter update indication message, the O-RAN may send information of update failure and configuration parameter information of the current O-RAN to the first entity. If the O-RAN succeeds in updating the configuration parameters according to the configuration parameter update indication message, the O-RAN may send information of successful update and the configuration parameter information after the O-RAN update to the first entity.

S508, the first entity sends a configuration parameter updating response message to the MEC application. Correspondingly, the MEC application receives a configuration parameter update response message sent by the first entity.

Case 2.2, the first request message is used to request the first entity to create a configuration parameter update event.

S509, the first entity creates a configuration parameter update event according to the first request message.

The configuration parameter update event is an event which triggers the first entity to send a configuration parameter update indication message to the capability opening agent module. The configuration parameter update indication message includes configuration parameters that the O-RAN needs to update.

In one possible implementation, the configuration parameter update event may include a trigger condition instructing the O-RAN to update the configuration parameters.

When the configuration parameter update event is satisfied, the first entity may perform step S510.

S510, the first entity sends a configuration parameter updating indication message to the O-RAN.

Wherein, the configuration parameter update indication message is used for indicating the O-RAN to update the configuration parameters.

In one possible implementation, the configuration parameter update event includes configuration parameter information to be updated by the O-RAN. When the configuration parameter update event is satisfied, the first entity sends a configuration parameter update indication message to the O-RAN.

In another possible implementation manner, when the configuration parameter update event is satisfied, the first entity requests, to the MEC application, configuration parameter information to be updated by the O-RAN according to the configuration parameter update event, so as to send a configuration parameter update indication message to the O-RAN.

Through the technical scheme, the first entity in the application can realize the communication between the MEC system and the O-RAN in an active or event-triggered mode, so that the O-RAN opens the wireless network capability of the O-RAN. Compared with the communication scheme in the prior art, the O-RAN capability opening method can more flexibly execute O-RAN capability opening operation.

Hereinafter, before the step S401, the method further includes a process of subscribing the O-RAN capability opening service to the first entity by the MEC application.

As a possible embodiment of the present application, in conjunction with fig. 4 to 5, as shown in fig. 6, before the step S401, the method further includes the following steps S601 to S606:

s601, the MEC application sends a first service registration request message to the service registration center SR. Accordingly, the SR receives a first service registration request message transmitted by the MEC application.

Illustratively, the service information of the first entity includes communication address, processing service and capability status information of the first entity.

S604, the SR sends a second service registration response message to the first entity. Correspondingly, the first entity receives a second service registration response message sent by the SR.

Wherein the second service registration response message includes a registration result of the first entity.

In the present application, the order of the steps S601 and S603 is not limited, and the step S603 may be executed after the step S601 or before the step S601.

S605, the MEC application sends the second request message to the first entity. Accordingly, the first entity receives the second request message sent by the MEC application.

Wherein the second request message is used for requesting to subscribe to the O-RAN capability open service of the first entity.

It should be noted that, before the MEC application sends the first request message to the first entity, the MEC application may also subscribe to the O-RAN capability open service of the first entity by sending the second request message to the first entity.

S606, the first entity sends a second request response message to the MEC application. Accordingly, the MEC application receives the second request response message sent by the first entity.

Wherein the second request response message includes a subscription result of the O-RAN capability open service.
