Description

Wireless service opening method and first execution body

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a wireless service opening method and a first execution body.

Background

Open and intelligent radio access networks O-RAN (Open and Smart Radio Access Network) are proposed by the O-RAN alliance established by operators, which proposes a Radio Intelligent Controller (RIC) in comparison to existing radio access network architecture and functions. Towards abnormal business cooperation among cells, user-level optimization, high operation and maintenance complexity of a multi-band/standard network and diversified service application requirements, RIC is introduced, management and control capability enhancement is realized, user experience is optimized, and network performance is improved.

According to the definition of network service or capability opening (exposure) existing in 3GPP (third generation partnership project), since interfacing with a system other than 3GPP is required, network service or capability opening is performed with core network functions SCEF (Service Capability Exposure Function, network traffic capability opening function) and NEF (Network Exposure Function, network opening function), mainly opening services or capabilities provided by network functions connected to SCEF and NEF.

However, the O-RAN currently defines only E2 interface standardization between a Near real-time wireless intelligent controller (Near-RT RIC) and a base station (such as a gNB or eNB) or a base station subsystem (part of baseband functions such as CU or DU), and cannot provide Near real-time wireless capability/service/information for functions other than the wireless network functions, thereby causing limitation in wireless service opening. While SCEF and NEF are defined in the existing 3GPP for opening network capabilities/services/information to systems other than 3GPP, SCEF and NEF currently open capabilities/services/information of a core network function connected thereto, and there is a limitation in opening wireless capabilities/services/information inside a radio access network.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In the embodiment of the invention, a wireless service opening method and a first execution body are provided to solve the problem that the opening of wireless capacity/service/information in the existing wireless access network is limited.

Referring to fig. 1, fig. 1 is a flowchart of a wireless service opening method according to an embodiment of the present invention, which is used by a first executing body, where the first executing body is a network opening function NEF (Network Exposure Function), a network service capability opening function SCEF (Service Capability Exposure Function), a Near real-time wireless intelligent controller Near-RT RIC in a wireless access network, or a wireless access network opening function RAN EF (Radio access network exposure function). As shown in fig. 1, the wireless service opening method includes the steps of:

step 101: receiving a first request sent by an application function entity or a mobile edge computing entity;

The application function entity Application Function, abbreviated as AF, the mobile edge Computing entity, multi-ACCESS EDGE Computing, abbreviated as MEC, may also be referred to as a Multi-access edge Computing entity, etc. The AF/MEC may send a first request to the first executing entity requesting wireless capability, wireless services or wireless information.

Step 102: and responding to the first request, and sending the first wireless capability, the first wireless service or the first wireless information of the first network function entity corresponding to the first request in the wireless access network to the application function entity or the mobile edge computing entity.

When the wireless access network adopts an O-RAN architecture, a wireless intelligent controller (RIC) in the O-RAN has the capabilities of wireless big data, artificial intelligence technology, wireless service opening and the like, so that the wireless access network is intelligent. As shown in fig. 2, which is a system architecture diagram of the O-RAN, the wireless intelligent controllers include Non-real-time wireless intelligent controllers (Non-RT RIC) and Near-real-time wireless intelligent controllers (Near-RT RIC). From the control plane, the near-real-time wireless intelligent controller receives the information of the network management (network management entity) and the non-real-time wireless intelligent controller, and feeds back the related information. From the network function perspective, the near real-time wireless intelligent controller is connected with a base station (such as gNB or eNB, etc.) or a base station subsystem (part of baseband functions such as CU-CP, CU-UP or DU), sends configuration or control information, and receives information such as measurement provided by the base station or the base station subsystem function, wherein CP is a control plane, UP is a user plane, and RRU is a radio frequency unit in FIG. 2.

The near real-time wireless intelligent controller plays two important roles: firstly, according to available information and scene requirements, receiving data from a base station or a base station subsystem, and sending strategy or control information to perform enhancement control; and secondly, providing near real-time wireless capability/service/information for functions other than the functions in the wireless access network according to the available information and scene requirements. From a deployment modality, near-RT RIC has both freestanding and non-freestanding. By standalone is meant that the Near-RT RIC is independent of the standalone device morphology outside of the eNB or gNB devices; non-freestanding means that the Near-RT RIC and the eNB/gNB are taken together to form one device. Early O-RAN standardization focuses on E2 interface standardization between Near-RT RIC and base stations (e.g., gNB or eNB, etc.) or base station subsystems (e.g., partial baseband functions such as CU-CP, CU-UP, or DU), but is not temporarily involved with interfaces of Near-RT RIC with additional functions to the network functions of the radio access network.

According to the definition of network service or capability opening (exposure) existing in 3GPP (third generation partnership project), since interfacing with a system other than 3GPP is required, network service or capability opening is performed with core network functions SCEF and NEF, mainly opening services or capabilities provided by network functions connected to SCEF and NEF. For the 3 GPP-defined 4G and 5G network open (network) architecture, it is explicitly indicated by note 2 in 23.501 system architecture that the 3GPP interface refers to an interface between NEF and 5GC (5G core network) network functions, such as an N29 interface between NEF and SMF (Session Management Function ), an N30 interface between NEF and PCF (Policy Control Function, policy control function entity), etc. Although the 23.682 system architecture does not illustrate the details of the 3GPP interface, it is known from the 23.682 system architecture that SCEF is functionally connected to a 4G core network (e.g., MME (Mobility MANAGEMENT ENTITY, mobility management entity)). Thus, in existing 3GPP network capability opening architecture, the openable capabilities/services/information mainly include capabilities based on core network functions, including radio access network capabilities/services/information that the core network functions interact with the radio access network over Ng or S1 interfaces, and not including capabilities/services/information that are available inside the radio access network.

In this embodiment of the present application, after receiving the first request, the first executing body may provide the first wireless capability, the first wireless service, or the first wireless information of the first network function entity corresponding to the first request in the wireless access network to the AF/MEC in response to the first request. Thus, the opening of the first wireless capability, the first wireless service or the first wireless information of the first network functional entity in the wireless access network can be realized.

In the wireless service opening method in the embodiment of the present application, the first execution body may be a NEF (network opening function entity), an SCEF (network service capability opening function entity), a Near-real-time wireless intelligent controller RIC (Near real-time wireless intelligent controller) or a RAN EF (radio access network opening function) in a wireless access network, and after receiving a first request sent by an AF/MEC, the first execution body may provide the AF/MEC with a first wireless capability, a first wireless service or first wireless information of a first network function entity corresponding to the first request in the wireless access network, so as to implement opening of the first wireless capability, the first wireless service or the first wireless information of the first network function entity in the wireless access network.

In one embodiment, the RAN EF is connected to an application function entity or a mobile edge computing entity, and N network function entities, N being an integer greater than or equal to 1, the N network function entities comprising a first network function entity;

the RAN EF functions include at least one of the following:

A safety function;

providing temporary UE identification;

managing service;

service providing and consuming functions.

The RAN EF serves as a radio service opening function, and connects the AF/MEC with network function entities of the radio access network (e.g., near-RT RIC, gNB, eNB, CU, DU, UE, etc.). One RAN EF may connect to a plurality of radio network function entities, logically in a one-to-many relationship. The traditional wireless access network is not connected with an external application function entity AF through a direct channel, and provides positioning of wireless service with low time delay opening according to the RAN EF. The functions of the RAN EF may include security functions, temporary UE identity provisioning, service management, service provisioning and consumption functions. Security functions include authentication and authentication, security of user identification information used externally and internally, and the like. The RAN EF needs to support a temporary security mechanism for low latency applications, for example, to provide an hour-level security authorization for a certain application, and cannot be used after expiration. The RAN EF may also support temporary UE identities for identifying UEs during external application functions and radio access network interactions, which may avoid security problems caused by permanent identity exposure. The service management refers to supporting the network function entity and/or the external application function entity in the wireless access network to perform service registration, discovery, subscription and other service management flows. The service providing/consuming function means that both a network function entity and an external application function entity in the radio access network can act as a service provider or consumer. Therefore, not only the radio network service can be opened to the outside through the RAN EF, but also the information or service of the application function entity can be directly used by the radio access network through the RAN EF.

In one embodiment, the security function implementation includes:

Receiving an authorization request sent by an application function entity or a mobile edge computing entity through a RAN EF;

in response to the authorization request, sending an authorization response to the application function entity or the mobile edge computing entity through the RAN EF, the authorization response including temporary authorization authentication information;

Receiving a first request sent by an application function entity or a mobile edge computing entity, including:

A first request sent by an application function entity or a mobile edge computing entity based on temporary authorization authentication information is received by the RAN EF.

That is, before the AF/MEC sends the first request, the AF/MEC needs to perform authorization authentication, that is, before the first executing body receives the first request sent by the AF/MEC, the AF/MEC sends an authorization request to the first executing body, the first executing body receives the authorization request through the RAN EF, and sends an authorization response including temporary authorization authentication information to the AF/MEC through the RAN EF in response to the authorization request, and after the AF/MEC receives the authorization response, the AF/MEC can send the first request to the RAN EF based on the temporary authorization authentication information therein, so that the security function of the RAN EF can be implemented.

In one embodiment, a service management implementation includes:

receiving a service discovery request sent by an application function entity or a mobile edge computing entity based on temporary authorization authentication information through a RAN EF;

In response to the service discovery request, sending a first response to the application function entity or the mobile edge computing entity through the RAN EF, the first response comprising the available service information;

receiving, by the RAN EF, a first request sent by an application function entity or a mobile edge computing entity based on temporary authorization authentication information, including:

the method comprises receiving, by the RAN EF, a first request sent by an application function entity or a mobile edge computing entity based on temporary authorization authentication information after receiving the first response.

That is, before the AF/MEC receives the authorization response and sends the first request, that is, before the first executing body receives the first request sent by the AF/MEC based on the temporary authorization authentication information, the AF/MEC needs to send a service discovery request to the first executing body, the first executing body receives the service discovery request through the RAN EF, and in response to the service discovery request, can send a first response including usable service information to the AF/MEC through the RAN EF, and after the AF/MEC receives the first response, can send the first request to the RAN EF based on the temporary authorization authentication information, so that part of the service management functions of the RAN EF can be implemented.

In one embodiment, the service management implementation further comprises:

Receiving a registration request for the usable service information sent after receiving the first response by the application function entity or the mobile edge computing entity through the RANEF;

In response to the registration request, sending a registration response to the application function entity or the mobile edge computing entity through the RAN EF;

Receiving, by the RAN EF, a first request sent by the application function entity or the mobile edge computing entity based on the temporary authorization authentication information after receiving the first response, including:

The first request sent by the application function entity or the mobile edge computing entity based on the temporary authorization authentication information after receiving the registration response is received by the RAN EF.

After the AF/MEC receives the first response, before sending the first request, it also needs to send a registration request for the usable service information to the first executing body, after the first executing body receives the registration request through the RAN EF, in response to the registration request, it can send a registration response to the AF/MEC through the RAN EF, after the AF/MEC receives the registration response, it can send the first request based on the temporary authorization authentication information, so the first executing body can receive the first request through the RAN EF.

In one embodiment, the first request includes first user identification information;

an implementation manner of temporary UE identity provision, comprising:

determining a temporary UE identity based on the first user identity information;

determining second user identification information based on the temporary UE identity;

Responding to the first request, sending first wireless capability, first wireless service or first wireless information of a first network function entity corresponding to the first request in the wireless access network to an application function entity or a mobile edge computing entity, wherein the first wireless capability, the first wireless service or the first wireless information comprises:

the first radio capability, the first radio service or the first radio information associated with the second user identification information is sent to the application function entity or the mobile edge computing entity via the RAN EF.

The RAN side has no permanent UE identity, but the RAN EF can provide a temporary UE identity, the first user identity information can be understood as the UE identity used by the AF/MEC, and the RAN EF can be mapped with the AF/MEC and the existing wireless UE identities (such as TMSI, GUTI, C-RNTI and NGAP-UE-ID), so that the RAN EF provides a temporary UE identity consistent with both the AF/MEC and the first network function entity during the wireless service opening period. That is, the first execution body may determine the temporary UE identity based on the first UE identity information, and then determine the second UE identity information according to the temporary UE identity, where the second UE identity information may be understood as a user identity on the radio access network side, so that association between the UE identity on the AF/MEC side and the user identity on the radio access network side is achieved by the temporary UE identity provided by the RAN EF. In this way, the functionality provided by the temporary UE identity of the RAN EF is implemented. The method comprises the steps that the RAN EF sends first wireless capacity, first wireless service or first wireless information which is associated with second user identification information of a first network function entity to an application function entity or a mobile edge computing entity, and the first wireless capacity, the first wireless service or the first wireless information which is associated with the second user identification information is opened to the AF/MEC.

In one embodiment, the first execution body is a Near-RT RIC, where the Near-RT RIC has a radio access network open function RAN EF, and the Near-RT RIC is provided with an E3 interface for connecting an application function entity or a mobile edge computing entity.

The Near-RT RIC has a radio access network opening function RAN EF, and it can be understood that the Near-RT RIC is combined with the RAN EF, and the radio access network opening function RAN EF is added to the Near-RT RIC. In this way, the Near-RT RIC, which is the first execution subject, may receive information sent by the AF/MEC through the RAN EF and send information to the AF/MEC through the RAN EF, i.e., the Near-RT RIC may implement communication with the AF/MEC through the RAN EF, and as shown in fig. 3, the RAN EF may receive information sent by the AF/MEC through the E3 interface and send information to the AF/MEC through the E3 interface. As an example, as shown in fig. 3, the RAN EF may receive the first radio capability, the first radio service, or the first radio information sent by the first network function entity (e.g., gNB, eNB, CU, DU, etc.) through the E2 interface, and transmit the first radio capability, the first radio service, or the first radio information to the AF/MEC through the E3 interface. SMO (SERVICE MANAGEMENT AND orchestration framework) in fig. 3 is a network management/billing and orchestration system.

For example, the O-RAN based wireless service opening, O-RAN based existing protocol definition, near-RT RIC may form wireless services/capabilities/information based on information reported by the base station in Near real time for demand. The RAN EF can thus cooperate with the Near-RT RIC to complete wireless side opening based on existing O-RAN protocols. Thus, as shown in fig. 3, RAN EF is a new function of the existing Near-RT RIC, and the new part of Near-RT RIC directly provides an interface E3 that is open to the external system. E2 interface connects Near-RT RIC and network functional entity (e.g. gNB, eNB, CU, DU etc.), a scheme that Near-RT RIC faces to multiple external applications is mainly combined with the existing edge calculation, and meets the requirement of high-requirement business on more time-efficient network capability/service/information. For the case of lower latency transport networks, near-RT RIC may also be deployed in a city or county area, so that edge scenarios may also interact directly with edge applications.

The Near-RT RIC provides an open function to an external system, and can support external configuration information to be sent to the wireless access network, and the wireless access network is open to services/capabilities of external configuration. Presetting conditions: the Near-RT RIC has established an E2 interface with a base station or base station subsystem, which E2 interface can subscribe to reports, controls, policies, etc. inside the base station. AF/MEC and Near-RT RIC have network connection basis.

As shown in fig. 4, first, the AF/MEC sends an authorization request to the Near-RT RIC over the E3 interface;

The Near-RT RIC then performs an authorization response based on the known trusted AF/MEC list, etc., where temporary authorization authentication information (e.g., tokens) and a validity period are provided.

The AF/MEC uses the temporary authorization authentication information to send a service discovery request to the Near-RT RIC.

The Near-RT RIC returns a service discovery response, namely a first response, to the AF/MEC according to the authority, the strategy and other information of the AF/MEC, wherein the service discovery response can comprise usable service information.

The AF/MEC can register available service information such as the number of video clips and the code rate size with the Near-RT RIC, i.e. the AF/MEC can send a registration request to the Near-RT RIC.

The Near-RT RIC may provide a service registration response to the AF/MEC.

The AF/MEC uses the temporary authorization authentication information to send a cell-level/user-level wireless information request, namely a first request, to the Near-RT RIC, and if the request is user-level wireless information, the AF/MEC needs to carry first user identification information.

The Near-RT RIC sends a cell-level/user-level wireless information response, which includes a first wireless capability, a first wireless service, or first wireless information of a first network function entity corresponding to the first request, and if the response is user-level wireless information, the Near-RT RIC needs to associate the first user identifier with a second user identifier of a wireless side to provide the second user wireless information.

As shown in fig. 5, in one embodiment, the first execution body is RAN EF, which is an independent network function, and is connected to the Near-RT RIC, the centralized unit CU, the distributed unit DU, the user equipment UE, the 5G base station gNB, and the 4G base station eNB.

I.e. the RAN EF is one network entity and the Near-RT RIC is another network entity, i.e. the RAN EF and the Near-RT RIC are two separate network entities, the RAN EF and the Near-RT RIC not belonging to the same entity, the RAN EF being in communication connection with the Near-RT RIC. Since the first executing body in this embodiment is a RAN EF, the above-mentioned processes of receiving by the RAN EF and transmitting by the RAN EF can be understood as a RAN EF receiving and transmitting process.

In the present embodiment, the radio service opening is based on the O-RAN and 3GPP, and is defined based on the O-RAN and 3GPP existing protocols, and multiple network functions are involved for the 4G and 5G radio access networks, so that the RAN EF independently serves as one network function, and can connect at least one of the Near-RT RIC, eNB, gNB, CU, DU and the UE.

In one embodiment, the first execution body is NEF or SCEF, and the second network functional entity in the radio access network is connected to the NEF or SCEF through the first interface;

Adding a first event in a message format of the first request and detecting a network function entity of the first event, wherein the first event comprises first wireless network information, the first wireless network information comprises information provided by at least one of a Near-RT RIC, gNB, eNB, DU and a CU, and the network function entity of the first event comprises at least one of a Near-RT RIC, gNB, eNB, DU and a CU;

Sending a first request after adding a first event and detecting the network function entity of the first event to a second network function entity through a first interface; wherein the second network functional entity comprises at least one of a Near-RT RIC, gNB, eNB, DU, and a CU;

Receiving a first wireless capability, a first wireless service or first wireless information of a first network function entity sent by a second network function entity through a first interface;

The first wireless capability, the first wireless service or the first wireless information is sent to the application function entity or the mobile edge computing entity.

That is, in this embodiment, an interface between the NEF/SCEF and the second network functional entity in the radio access network, that is, the first interface, may be newly added. After receiving the first request sent by the AF/MEC, the NEF/SCEF may add a first event to the first request and detect a network function entity of the first event, update the first request, then send the first request after adding the first event and detecting the network function entity of the first event to the second network function entity through the first interface, after receiving the first request, the second network function entity may send the first wireless capability, the first wireless service or the first wireless information of the first network function entity to the NEF/SCEF, and then send the first wireless capability, the first wireless service or the first wireless information of the first network function entity to the AF/MEC through the first interface.

As shown in fig. 6, as an example, the first interface may include a first sub-interface and a second sub-interface, the gNB and the eNB may directly connect the NEF/SCEF through the newly added first sub-interface, the NEF/SCEF may send a first request to the gNB and/or the eNB after adding the first event and detecting the network function entity of the first event, and the gNB and/or the eNB may send the first wireless capability, the first wireless service, or the first wireless information of the gNB and/or the eNB to the NEF/SCEF through the first sub-interface. In addition, the Near-RT RIC may connect to the NEF/SCEF through a newly added second sub-interface, and may also connect between at least one of gNB, eNB, CU and the DU and the NEF/SCEF through at least one of E2 interface connection gNB, eNB, CU and the DU, i.e., the Near-RT RIC may send a first request to the Near-RT RIC after adding the first event and detecting the network function entity of the first event, and since the Near-RT RIC is connected to at least one of gNB, eNB, CU and the DU, the Near-RT RIC may acquire the first wireless capability, the first wireless service, or the first wireless information of at least one of gNB, eNB, CU and the DU after receiving the first request, and then send it to the AF/MEC through the second sub-interface. In addition, as shown in FIG. 6, NEF/SCEF may interface with 3 GPP-defined network functions, e.g., AMF/SMF, etc., via a 3GPP interface.

After the NEF/SCFF receives the first request, a row of definitions about radio capability/information openness may be added to the first request, i.e. adding a first event and detecting a network function body of the first event, in this example, the first event includes first radio network information, which includes information provided by at least one of a Near-RT RIC, gNB, eNB, DU and a CU, and the network function entity detecting the first event includes at least one of a Near-RT RIC, gNB, eNB, DU and a CU, as shown in table 1 below.

It should be noted that, in this embodiment, the wireless service opening scheme based on the NEF/SCEF multiplexes the existing NEF/SCEF, and for 4G, an interface between the Near-RT RIC and SCEF needs to be newly added, and for 5G, an interface between the Near-RT RIC and the NEF needs to be added. NEF/SCEF is in one-to-many relationship with Near-RT RICs, eNB, gNB, DU, CU, i.e., one NEF/SCEF versus multiple Near-RT RICs and or eNBs and or gNB and/or DUs and/or CUs. The newly added interface adopts a service mode, which has larger mechanism difference with Ng/S1/X2/Xn of the existing eNB and gNB, and the base station needs to be connected with NEF/SCEF by the newly added service interface. Because the Near-RT RIC is connected with the eNB/gNB, the NEF/SCEF can also be indirectly connected with the eNB/gNB through the Near-RT RIC in the scheme, and the existing base station does not need to increase a service interface with the NEF/SCEF.

For user-level information, a new UE identity analysis and association function is required, and a request sent to the Near-RT RIC/eNB/gNBDU/CU needs to carry the UE identity which can be identified by the Near-RT RIC/eNB/gNBDU/CU. An alternative solution includes: first the Near-RT RIC/eNB/gNBDU/CU needs to report the UE ID information it uses to the core network functions, e.g. UDR (Unified Data Repository ). Then when the related user-level information is open, the problem that the UE identity used in the SCEF/NEF is inconsistent with the UE identity used in the Near-RT RIC exists, and then the NEF/SCEF can map the corresponding ID into the Near-RT RIC ID and the UE ID used in the Near-RT RIC according to the original UE identity of the core network and the UE ID information reported by the Near-RT RIC. In turn, sends a request to the Near-RT RIC/eNB/gNBDU/CU corresponding to the ID (identity), which Near-RT RIC/eNB/gNBDU/CU can be locally associated to wireless capability, wireless service or wireless information according to the UE ID in the request, and responds.

In one embodiment, the first execution body is a NEF or SCEF, and the NEF or SCEF is connected to a network function entity in the radio access network through a third network function entity;

adding a second event in the message format of the first request and detecting a network function entity of the second event, wherein the second event comprises second wireless network information, the second wireless network information comprises information provided by at least one of gNB, eNB, DU and CU, and the network function entity of the second event comprises at least one of an access and mobility management function AMF, a session management function SMF, a mobility management entity MME, a serving general packet radio service support node SGSN, a user plane function UPF, gNB and an eNB;

Sending a first request after adding a second event and detecting the network function entity of the second event to the first network function entity through an NG interface or an S1 interface of the third network function entity; wherein the first network function entity comprises at least one of gNB, eNB, DU and CU, and the third network function entity comprises at least one of an access and mobility management function AMF, a session management function SMF, a mobility management entity MME, a serving general packet radio service support node SGSN, a user plane function UPF, a gNB, and an eNB;

Receiving first wireless capability, first wireless service or first wireless information sent by a third network function entity and received from a first network function entity through an NG interface or an S1 interface;

That is, in this embodiment, after the NEF/SCEF receives the first request sent by the AF/MEC, a second event may be added to the first request and a network function entity detecting the second event may update the first request, then the first request after adding the second event and the network function entity detecting the second event is sent to the first network function entity through the third network function entity, after the first network function entity receives the first request, the first network function entity may send the first wireless capability, the first wireless service or the first wireless information of the first network function entity to the third network function entity, and the third network function entity receives the first wireless capability, the first wireless service or the first wireless information sent by the first network function entity through the NG interface or the S1 interface and sends the first request to the NEF/SCEF, and after the NEF/SCEF receives the first wireless capability, the first wireless service or the first wireless information, the third network function entity sends the first wireless information to the AF/MEC.

For example, as shown in fig. 7, in this embodiment, the NEF/SCEF is connected to a third network function entity through a 3GPP interface, where the third network function entity is a network function defined by 3GPP, for example, may include at least one of an access and mobility management function AMF, a session management function SMF, a mobility management entity MME, a serving general packet radio service support node SGSN, a user plane function UPF, a gNB, and an eNB, the NEF or SCEF is connected to a network function entity in a radio access network (for example, a gNB/eNB/DU/CU in fig. 8, etc.) through the third network function entity, and optionally, the network function entity in the radio access network is connected to the third network function entity through an Ng/S1 interface, the gNB/eNB/DU/CU is connected to a Near-RT RIC through an E2 interface, and the gNB/eNB/DU/CU may send radio capability, radio service or radio information of the gNB/eNB/CU to the NEF/SCEF through the third network function entity, and may also receive Near-RT information through the third network function or the radio service/DU/CU.

In this embodiment, the wireless service based on Near-RT RIC and Ng/S1 ports is opened, and the present NEF/SCEF, AMF/SMF/UPF and E2 interfaces are multiplexed, and no new interfaces are added. The NEF/SCEF adds a second event to the first request, the second event including the second network information, and a network function entity detecting the second event, according to the received first request, the function needs to add an IE (Information Element ) of the wireless network information in an existing message format of the first request. For example, the first request after adding the second event may be sent to the corresponding eNB/gNB. The eNB/gNB sends the radio access network side information to AMF/SMF/UPF or MME/SGSN by means of a container (container) on the Ng/S1 interface, and the AMF/SMF/UPF or MME/SGSN sends the information to NEF/SCEF. As an example, two schemes are classified into a control plane and a user plane: the control plane scheme means that a container containing the information of the wireless access network side is borne on NG-C (NG interface-control plane) or S1-C (S1 interface-control plane), the information of the wireless access network side is sent to AMF or MME, and then the AMF or MME sends the information to NEF/SCEF, so that the AF/MEC is opened; for the user plane scheme, the container is carried on NG-U or S1-U, then SMF/UPF/SGSN can send information directly to AF/MEC, the analysis of radio access network side information is completed by AF/MEC, and not the content of network system defined by 3GPP is completed. With respect to the latter user plane scheme, one way of wireless service/capability/information opening is to provide information of external system opening through a local UPF connected to the MEC, based on the O-RAN and ETSI (European Telecommunications Standards Institute, european telecommunications standardization institute) MEC existing protocol definitions. The MEC is connected with the user plane of the base station through the local UPF to play a role of local shunting of partial services facing to the edge application scene. The services of MECs typically have higher requirements, such as low latency or large bandwidth, so the service requirements can be better met by the above-mentioned opening of wireless services/capabilities/information. Therefore, the solution needs to extend and define the opening of the interface between the base station and the local UPF to support the wireless service/capability/information, and one potential way is to add the channel of the user plane data packet, provide the wireless service/capability/information outwards along with the increase of the channel information, and receive the configuration information of the external to the wireless side.

As shown in table 2 below, for the control plane open scheme, a row of definitions about radio capability/information open may be added in the first request, i.e. adding a second event and detecting a network function body of the second event, in this example, the second event comprising second radio network information, the second radio network information comprising information provided by at least one of gNB, eNB, DU and CU, and the network function entity detecting the second event comprising at least one of AMF, MME, gNB and eNB.

As shown in table 3 below, for the user plane open scheme, a row of definitions about radio capability/information open may be added in the first request, i.e. adding a second event and detecting a network function body of the second event, in this example, the second event comprising second radio network information, the second radio network information comprising information provided by at least one of gNB, eNB, DU and CU, and the network function entity detecting the second event comprising at least one of SMF, SGSN, UPF, gNB and eNB.

Meanwhile, for the existing E2 interface, a service needs to be added to RIC SERVICES defined by the O-RAN-wg3.e2ap for wireless service opening, for example, called value added service. Then further Add the value added service related flow and message definitions, as shown in fig. 8, the E2 node may send an RIC value added service request to the Near-RT RIC, where the RIC value added service request needs to include a request ID (E2 node request ID) and RIC value added service detailed information (RIC Add-on SERVICE DETAILS), and after receiving the RIC value added service request, the Near-RT RIC may return a RIC value added service response to the E2 node.

In one embodiment, the first execution subject is a Near-RT RIC, the Near-RT RIC being connected to a Non-real-time wireless intelligent controller Non-RT RIC or a network management entity;

Receiving a first request sent by an application function entity or a mobile edge computing entity forwarded by a Non-RT RIC or a network management entity;

transmitting, to an application function entity or a mobile edge computing entity, first wireless capability, first wireless service, or first wireless information of a first network function entity corresponding to a first request in a wireless access network, including:

And sending the first wireless capability, the first wireless service or the first wireless information of the first network function entity corresponding to the first request in the wireless access network to the Non-RT RIC or the network management entity through the A1 interface or the O1 interface, and sending the first wireless capability, the first wireless service or the first wireless information to the application function entity or the mobile edge computing entity through the Non-RT RIC or the network management entity.

The Non-RT RIC or network management entity is also connected to the AF/MEC, it being understood that the Non-RT RIC or network management entity is connected between the AF/MEC and the Near-RT RIC. The Non-RT RIC or the network management entity can receive the first request sent by the AF/MEC, forward the first request to the Near-RT RIC, send the first wireless capability, the first wireless service or the first wireless information of the first network function entity corresponding to the first request in the wireless access network to the Non-RT RIC or the network management entity after the Near-RT RIC receives the first request, and send the first wireless capability, the first wireless service or the first wireless information to the AF/MEC through the Non-RT RIC or the network management entity. It should be noted that, the Near-RT RIC is connected with the Non-RT RIC through an A1 interface, is connected with the network management entity through an O1 interface, and can send the first wireless capability, the first wireless service or the first wireless information of the first network function entity corresponding to the first request in the wireless access network to the Non-RT RIC through the A1 interface, and sends the first wireless capability, the first wireless service or the first wireless information to the application function entity or the mobile edge calculation entity through the Non-RT RIC; or the Near-RT RIC may send the first wireless capability, the first wireless service or the first wireless information of the first network function entity corresponding to the first request in the wireless access network to the network management entity through the O1 interface, and send the first wireless capability, the first wireless service or the first wireless information to the application function entity or the mobile edge computing entity through the network management entity.

It should be noted that, in this embodiment, the wireless service opening scheme based on the Near-RT RIC and the network manager multiplexes the management service interfaces of the existing network manager, provides information of opening the external system through the Non-RT RIC or the network manager, and has no newly added interface. Then a new wireless capability open service needs to be added to the A1 or O1 interface of the Near-RT RIC, and a Non-real-time wireless intelligent controller (Non-RT RIC) or a network manager can consume the service through the A1/O1 interface.

At present, the A1 interface mainly supports Non-RT RIC to send policy (policy) and enhancement information (ENRICHMENT INFORMATION) to Near-RT RIC, and Near-RT RIC feeds back the two types of information. When opened through Non-RT RICs, the definition of the A1 interface needs to be extended. First, the extension of the A1 interface, e.g., adding a type of information, A1-RAN-S, supports the Near-RT RIC to send wireless services/capabilities/information in the direction from Near-RT RIC to Non-RT RIC. Because such information is used to open to the outside, non-RT RIC may or may not provide feedback.

If the network management interface (e.g. O1 interface) is used for opening, the management model of the Near-RT RIC must include a content of the type of wireless capability opening, where the wireless capability/information that can be opened by the Near-RT RIC can be specifically listed, for example, the above-mentioned two basic information of cell level information and user level information, and the first information obtained after processing (such as positioning, track, etc.). The management model for the eNB/gNB needs to add a wireless capability open management service based on the existing FCAPS (configuration, accounting, performance, security) management service, and also provides a supportable wireless capability open information list under the management service class.

In the following, how to provide a function of opening an external system through a Non-RT RIC is described in a specific embodiment, where the embodiment may also support sending of external configuration information to a radio access network, where the radio network opens services/capabilities/information configured externally. Presetting conditions: the Non-RT RIC and the Near-RT RIC have established a connection, and the Non-RT RIC and an external system (AF/MEC) have established a connection (which may be a direct connection or an indirect connection through NWDAF (Network DATA ANALYTICS Function); near-RT RIC has established an E2 interface with a base station or base station subsystem through which reports, controls, policies, etc. inside the base station can be subscribed to.

Firstly, the AF/MEC sends a first request to the Non-RT RIC through a connection, requesting wireless services/capabilities/information with high timeliness and finer granularity;

the Non-RT RIC then finds the appropriate Near-RT RIC based on the first request, which is then sent to the Near-RT RIC over the A1 interface.

The Near-RT RIC sends wireless services/capabilities/information to the Non-RT RIC over the A1 interface.

Non-RT RIC opens wireless services/capabilities/information to AF/MEC.

In the following, how to provide a function of opening an external system through a network management (network management entity) is described in an embodiment, where the embodiment may also support external configuration information to be sent to a radio access network, where the radio network opens services/capabilities/information configured externally. Presetting conditions: the network manager has established a connection with an external system (e.g., a connection may be established through NWDAF, or through a manual interface), the Near-RT RIC or the base station has established a connection with the network manager, optionally the Near-RT RIC has established an E2 interface with the base station or base station subsystem, reports, controls, policies, etc. inside the base station may be subscribed to through the E2 interface, and the Non-RT RIC and Near-RT RIC have established a connection.

Firstly, AF/MEC sends a first request to network manager through connection to request wireless service/capability/information with high timeliness and finer granularity;

Then, the network manager finds a suitable Near-RT RIC or base station (or base station subsystem) according to the first request, and then sends the first request through the network manager interface.

The Near-RT RIC or base station (or base station subsystem) sends wireless services/capabilities/information to the Non-RT RIC via the network management interface.

The network manager opens wireless services/capabilities/information to the AF/MEC.

In the wireless service opening scheme provided by the embodiment of the application, the problem of opening wireless service/capability/information is mainly solved, and the wireless access network is mainly limited to reporting original wireless information/data, and forms wireless service/capability/information by processing on the basis of the existing wireless data and interacts with the outside through a servitization interface. There is no limitation as to which function of the radio access network the radio service/capability/information is generated by. The radio services/capabilities/information based on the O-RAN architecture is mainly generated and provided by the Near-RT RIC, and for non-O-RAN architectures other functions of the radio network (e.g. base stations or UEs) are possible.

In the prior art solutions, a solution of wireless service/capability/information opening on a non Ng or S1 interface is not provided. The solution of the embodiment of the present application firstly proposes that the service/capability/information that can be opened by the radio access network includes radio access network information that is not transmitted on Ng or S1 interface, and may include two kinds of information at cell level and/or user level and/or radio access network information on Ng/S1 interface and/or first information generated by processing or abstracting (abscission) based on the cell level and/or user level information, for example, prediction information of user trace, prediction information of available bandwidth of user, etc. may be generated by algorithm based on the above information. Second, based on the O-RAN and 3GPP proposal definitions, specific wireless service/capability/information opening schemes are proposed.
