The present disclosure relates to management of a test profile of an IOT device in an M-Plane of an O-RAN.
For the purpose of the so-called open radio access network (RAN) in a mobile communication system, “Open RAN”, “O-RAN”, “vRAN” etc. are being considered. In this specification, “O-RAN” is used as a comprehensive term for such various “open radio access networks”. Therefore, the interpretation of “O-RAN” in this specification is not limited to the standard and/or the specification of the same name “O-RAN” specified by the O-RAN Alliance.
A radio unit (RU) in the O-RAN is called an O-RU and provides a communication cell to a communication device (UE: User Equipment). An O-RU is controlled by a RAN node composed by an O-CU, which is a central unit (CU), and/or an O-DU, which is distributed unit (DU). Furthermore, a RAN node is controlled by a higher-level controller such as a Near-RT RIC (Near-Real Time RAN Intelligent Controller) and/or a Non-RT RIC (Non-Real Time RAN Intelligent Controller). In the O-RAN, a virtual infrastructure also referred to as O-Cloud that virtually manages a set of a plurality of RAN nodes is also provided.
In the conventional O-RAN, all O-Rus have been required to support the Ipv4 of the Internet Protocol version. However, some telecommunication carriers that operate O-RANS (hereinafter also referred to as operators or carriers) may not use Ipv4, resulting in the Ipv4 functionality implemented in O-Rus in vain. In addition, the test profile for IOT (Internet of Things) devices in the M-Plane of the conventional O-RAN only supports Ipv4, and does not support TLS (Transport Layer Security) etc.
The present disclosure was made in view of these circumstances, and its purpose is to provide a radio access network control apparatus and the like that can alleviate the restrictions about the test profile of IOT devices in the M-Plane of the O-RAN.
In order to solve the above problem, a radio access network control apparatus in a certain aspect of the present disclosure comprises at least one processor that performs: by a test profile management unit, managing a test profile of an IOT device in an M-Plane of an O-RAN capable of supporting Ipv6.
According to this aspect, the test profile of the IOT device in the M-Plane of the O-RAN is capable of supporting Ipv6, thereby alleviating the conventional restrictions about such test profile.
Another aspect of the present disclosure is also a radio access network control apparatus. The apparatus comprises at least one processor that performs: by a test profile management unit, managing a test profile of an IOT device in an M-Plane of an O-RAN capable of supporting TLS.
According to this aspect, the test profile of the IOT device in the M-Plane of the O-RAN is capable of supporting TLS, thereby alleviating the conventional restrictions about such test profile.
Further another aspect of the present disclosure is a radio access network control method. The method comprises: managing a test profile of an IOT device in an M-Plane of an O-RAN capable of supporting Ipv6.
Further another aspect of the present disclosure is also a radio access network control method. The method comprises: managing a test profile of an IOT device in an M-Plane of an O-RAN capable of supporting TLS.
Further another aspect of the present disclosure is a computer-readable medium. The computer-readable medium stores a radio access network control program causing a computer to perform: managing a test profile of an IOT device in an M-Plane of an O-RAN capable of supporting Ipv6.
Further another aspect of the present disclosure is a computer-readable medium. The computer-readable medium stores a radio access network control program causing a computer to perform: managing a test profile of an IOT device in an M-Plane of an O-RAN capable of supporting TLS.
In addition, any combination of the above components, and any conversion of the expression of the present disclosure among methods, devices, systems, recording media, computer programs and the like are also encompassed within this disclosure.
According to the present disclosure, the restrictions about the test profile of IOT devices in the M-Plane of the O-RAN can be alleviated.
In the following, the present embodiment is described in accordance with the “O-RAN” which is the standard and/or the specification developed by the O-RAN Alliance. Therefore, the known terms defined in “O-RAN” will be used in the present embodiment just for convenience, but the technologies according to this disclosure can be applied to other existing radio access networks such as “Open RAN” and “vRAN” and/or to similar radio access networks that may be developed in the future.
The illustrated RAN node has an O-CU, which is an O-RAN compliant central unit (CU), and/or O-DU, which is an O-RAN compliant distributed unit (DU). Both of the O-CU and the O-DU are responsible for baseband processing in the O-RAN, where the O-CU is provided on the side of the core network (not shown in the figure), and the O-DU is provided on the side of the O-RU, which is an O-RAN compliant radio unit (RU). The O-CU may be divided into the O-CU-CP, which constitutes the control plane (CP), and the O-CU-UP, which constitutes the user plane (UP). The O-CU and the O-DU may be integrally configured as a single baseband processing unit. The O-eNB as a base station compliant with the O-RAN and the 4th generation mobile communication system (4G), may be provided as a RAN node. One or more O-RUs are connected to each RAN node (O-CU/O-DU) and are controlled by the Near-RT RIC via each of the RAN nodes. A communication device (UE: User Equipment) in the communication cell provided by each O-RU can be connected to each of the O-RUs, and can perform mobile communication with the core network (not shown) via each RAN node (O-CU/O-DU).
Each RAN node (O-CU/O-DU) and the Near-RT RIC provide operational data etc. of each RAN node, each O-RU and each UE through the O1 interface to the SMO for so-called FCAPS (Fault, Configuration, Accounting, Performance, Security). The SMO updates as necessary the operational policy for each RAN node issued by the Non-RT RIC to the Near-RT RIC through the A1 interface, based on the operational data acquired through the O1 interface. The O-RUs may be connected to the SMO for the FCAPS by the O1 interface and/or other interfaces (e.g. Open Fronthaul M-Plane).
The O-Cloud as a virtual infrastructure that virtually manages a set of the plurality of RAN nodes (O-CUs/O-DUs) is connected to the SMO by an O2 interface. The SMO generates a resource allocation policy concerning the resource allocation and/or a workload management policy concerning the workload management of the plurality of RAN nodes, based on the operational states of the plurality of RAN nodes (O-CUs/O-DUs) acquired from the O-Cloud through the O2 interface, and issues them to the O-Cloud through the O2 interface.
The FOCOM manages resources in the O-Cloud, while receiving services from the IMS of the O-Cloud through the O2 interface (O2ims). The NFO realizes the orchestrated operation of a set of network functions (NFs) by a plurality of NF Deployments in the O-Cloud, while receiving services from the DMS of the O-Cloud through the O2 interface (O2dms). The NFO may utilize the OAM Function to access the deployed NFs through the O1 interface. The OAM Function is responsible for the FCAPS management of O-RAN managed entities such as the RAN nodes. The OAM Function in the present embodiment can be a functional block where callbacks are provided for receiving data concerning failures and/or operational states of the plurality of RAN nodes that are virtually managed by the O-Cloud, by monitoring processes or procedures over the O2ims and/or the O2dms. The IMS is responsible for managing the O-Cloud resources (hardware) and/or the software used for managing them, and provides services primarily to the FOCOM of the SMO. The DMS is responsible for the management of the plurality of NF Deployments in the O-Cloud, specifically the initiation, monitoring, termination etc., and provides services primarily to the NFO of the SMO.
The IP version setting unit 11 and/or the IP version detection unit 12 in the radio access network control apparatus 1 that controls the O-RAN including the O-RU as a radio unit, are capable of communicating in at least one direction via at least one interface with one or more O-RUs that are the main control targets. For example, as also schematically shown in
The IP version setting unit 11, which can communicate with the O-RU, is capable of setting the Internet Protocol version required for each O-RU to IPV6. The IP version setting unit 11 is also capable of setting the Internet Protocol version required for each O-RU to IPv4. Furthermore, the IP version setting unit 11 is also capable of setting the Internet Protocol version required for each O-RU to both IPv4 and IPV6. In other words, the IP version setting unit 11 is capable of setting the Internet Protocol version required for each O-RU to at least three patterns “IPV4”, “IPV6” and “both IPV4 and IPV6”. It should be noted that the expressions “IPV4”, “IPV6” and “both IPV4 and IPV6” focus only on IPv4 and/or IPv6. Therefore, they may include Internet Protocol versions other than IPv4 and IPV6.
The IP version detecting unit 12, which can communicate with the O-RU, is capable of detecting that IPv6 is included in the Internet Protocol version supported by each O-RU. The IP version detecting unit 12 is also capable of detecting that IPv4 is included in the Internet Protocol version supported by each O-RU. Furthermore, the IP version detecting unit 12 is also capable of detecting that both IPv4 and IPV6 are included in the Internet Protocol version supported by each O-RU. In other words, the IP version detecting unit 12 is capable of detecting that the Internet Protocol version supported by each O-RU is one of the at least three patterns “IPV4”, “IPV6” and “both IPV4 and IPV6”. It should be noted that the expressions “IPV4”, “IPV6” and “both IPv4 and IPV6” focus only on IPv4 and/or IPV6. Therefore, they may include Internet Protocol versions other than IPV4 and IPV6.
For example, the IP version detecting unit 12 can acquire the information suggesting the Internet Protocol version supported by each O-RU, directly or indirectly from each of such O-RUs, using the NETCONF or other network configuration protocols implemented via the O1 interface etc. In the NETCONF implemented via the O1 interface, the SMO functions as a NETCONF client and the O-RU (and/or the Near-RT RIC, the O-CU, the O-DU) functions as a NETCONF server. The SMO etc. as the NETCONF client may generate a list of interfaces supported by each O-RU as the NETCONF server through the RPC (Remote Procedure Call) constituting the NETCONF, and may estimate that, from the fact that an IPV4 container and/or an IPV6 container is present in the O-RAN interface module.
In the conventional O-RAN, all O-RUs have been required to support the IPv4 of the Internet Protocol version. However, some telecommunication carriers that operate O-RANS may not use IPv4, resulting in the IPV4 functionality implemented in O-RUs in vain. According to the present embodiment, the Internet Protocol version of the O-RU can be set to IPv6, thereby alleviating the conventional restrictions about the Internet Protocol version of the O-RU. In addition, according to the present embodiment, it is possible to detect that IPV6 is included in the Internet Protocol version supported by the O-RU, thereby alleviating the conventional restrictions about the Internet Protocol version of the O-RU.
The test profile management unit 13 manages a test profile e.g. for interoperability of IOT devices in the M-Plane of the O-RAN that can support IPV6 and/or TLS. As schematically shown in
For example, the test profile management unit 13 applying the test profile to each O-RU and/or each IOT device, the test profile management unit 13 having each O-RU and/or each IOT device conform to the test profile, the test profile management unit 13 having each O-RU and/or each IOT device follow the test profile, and the test profile management unit 13 imposing a restriction and/or a rule to each O-RU and/or each IOT device based on the test profile etc. should be interpreted as “management”, “administration” and/or “operation” of the test profile that the test profile management unit 13 is responsible for. In addition, the test profile management unit 13 applying the test profile to itself and/or the radio access network control apparatus 1, the test profile management unit 13 having itself and/or the radio access network control apparatus 1 conform to the test profile, the test profile management unit 13 having itself and/or the radio access network control apparatus 1 follow the test profile, the test profile management unit 13 imposing a restriction and/or a rule to itself and/or the radio access network control apparatus 1 based on the test profile, and the test profile management unit 13 having itself and/or the radio access network control apparatus 1 allow connection and/or communication of only O-RUs and/or only IOT devices that conform to the test profile etc. should be interpreted as “management”, “administration” and/or “operation” of the test profile that the test profile management unit 13 is responsible for.
In the above, the description “IPV6” in the item “IP Version” enables the test profile to support IPV6. Besides, the description “Entry 2) TLS1.2-SHA256” in the item “Hash algorithm for data integrity” and the description “Entry 2) TLS1.2-AES128-GCM” in the item “Cyphering algorithm” enable the test profile to support TLS. These items “Hash algorithm for data integrity” and “Cyphering algorithm” respectively include the descriptions on SSH “Entry 1) SSHv2-HMAC-SHA2-256” and “Entry 1) SSHv2-AES128-CTR”, in addition to the descriptions on TLS “Entry 2) TLS1.2-SHA256” and “Entry 2) TLS1.2-AES128-GCM”. “Entry 1” and “Entry 2” in these items may be appropriately selectable.
In the above, the description “DHCPv6 (Option: 16)” in the item “O-RU identification by DHCP option”, the description “Entry 1) IPv6 State-full address configuration” in the item “IP address assignment”, the description “Entry 2) Stateless Address Auto-Configuration (SLAAC)” in the item “IP address assignment”, and the description “DHCPv6 (Option: 17)” in the item “O-RU controller discovery” enable the test profile to support IPV6. “Entry 1” and “Entry 2” in the item “IP address assignment” may be appropriately selectable. Besides, the description “Entry 2) TLS—call home port 4335” in the item “NETCONF Call Home” and the description “Entry 2) TLS—X.509 Certificate” in the item “NETCONF Authentication” enable the test profile to support TLS. These items “NETCONF Call Home” and “NETCONF Authentication” respectively include the descriptions on SSH “Entry 1) SSH—call home port: 4334” and “Entry 1) SSH password-based authentication”, in addition to the descriptions on TLS “Entry 2) TLS—call home port 4335” and “Entry 2) TLS—X. 509 Certificate”. “Entry 1” and “Entry 2” in these items may be appropriately selectable.
