Description
Technical Field
The present invention relates to the field of O-RAN protocols and communication technologies, and in particular, to a service communication method, apparatus, electronic device, and storage medium.
Background
The mobile communication technology has been developed through the technologies of the first generation (1G), the second generation (2G), the third generation (3G) and the fourth generation (4G), and the time of the fifth generation development (5G mobile communication technology) has been recently entered. With the development of mobile communications, the conventional approach of providing access network equipment software and hardware by a single equipment provider and adopting a closed interface between access network elements has been disadvantageous to open interconnection of heterogeneous manufacturers, and in this case, an open radio access network (Open Radio Access Network, abbreviated as O-RAN) has been developed. O-RANs facilitate innovations by letting more manufacturers participate in the development of the RAN infrastructure.
Currently, O-RAN network architecture has been applied to 5G base stations. The O-RAN network architecture breaks down Radio access network equipment, such as 5G base stations, into Radio frequency units (O-RAN Radio units, O-RU), distributed units (O-RAN Distributed Unit, O-DUs) and centralized units (O-RAN Centralized Unit, O-CU). Wherein, the O-DU is mainly responsible for processing MAC layer functions and partial physical layer functions and the like of real-time requirements, and the O-RU is mainly responsible for converting digital signals from the O-DU into radio frequency signals and transmitting the radio frequency signals to the antenna, and converting the radio frequency signals from the antenna into digital signals and transmitting the digital signals to the O-DU. In addition, the O-DU performs real-time control and user plane communication control on the O-RU, and the O-DU and the O-RU are connected by using an O-RAN forwarding interface.
In a wireless communication network adopting an O-RAN protocol networking, one O-DU may be connected to one O-RU or may be connected to a plurality of O-RUs, and with the occurrence of a multi-system O-RU, a situation that a plurality of O-DUs are connected to one O-RU may also occur. In the scenario that a plurality of O-DUs are connected to one O-RU for service communication, the present inventors found that the O-RAN architecture in the prior art has the following problems:
fig. 1 is a schematic diagram of a connection between two O-DUs of different network types and a multi-system O-RU in the prior art. As shown in fig. 1, the O-DUs of two different network schemes are respectively an O-DU1 supporting the TD-LTE scheme and an O-DU2 supporting the 5G NR scheme, and the multi-scheme O-RU correspondingly supports both the TD-LTE and the 5G NR. Normally, O-DU1 should operate only TD-LTE of O-RU, O-DU2 should operate only 5G NR of O-RU, i.e. only A, B operation is allowed. However, since the O-RAN protocol of the current O-RU cannot distinguish which O-DU is operating, the O-DU1 can randomly manage 5G NR traffic, and the O-DU2 can also randomly manage TD-LTE traffic, i.e., there is illegal C, D operation. Taking the carrier establishment as an example, the O-DU1 can impersonate the carrier of the 5G NR issued by the O-DU2, and the O-DU2 can not create the carrier any more because the O-DU1 configures the 5G NR carrier. Meanwhile, data which is generated by TD-LTE on RU and needs to be uploaded to O-DU1 can not be perceived by a service layer to exist of O-DU1 and O-DU2, so that the data can be simultaneously reported to the O-DU1 and the O-DU2, and confusion is caused. It can be seen that, after the O-DU1 or the O-DU2 transmits service data to the O-RU, the O-RU receives the service data, and the data transmitted to a specific service layer through the O-RAN protocol cannot distinguish which O-DU is transmitted, and the O-RU cannot specify which O-DU the data is transmitted to. Meanwhile, the operation and data of each O-DU to the O-RU are mutually visible, isolation is avoided, and potential safety hazards and unauthorized access risks exist. Ideally, each O-DU is independent of the operation of the O-RU and does not interfere with each other, which is not satisfied by the current O-RAN protocol.
In a scenario that a plurality of O-DUs are connected with one O-RU to perform service communication, in order to achieve that each O-DU is independent to the operation of the O-RU and does not interfere with each other, a service communication method is needed to be provided at present, and when the O-DU side is operated, whether configuration is issued or data reporting is completely isolated and does not interfere with each other, potential safety hazards and unauthorized access risks are avoided, and anti-interference performance of service data is improved.

In the following detailed description of the present invention, certain specific details are set forth in detail. The present invention will be fully understood by those skilled in the art without the details described herein. Well-known methods, procedures, flows, components and circuits have not been described in detail so as not to obscure the nature of the invention.
Moreover, those of ordinary skill in the art will appreciate that the drawings are provided herein for illustrative purposes and that the drawings are not necessarily drawn to scale.
Meanwhile, it should be understood that in the following description, "circuit" refers to a conductive loop constituted by at least one element or sub-circuit through electrical connection or electromagnetic connection. When an element or circuit is referred to as being "connected to" another element or being "connected between" two nodes, it can be directly coupled or connected to the other element or intervening elements may be present and the connection between the elements may be physical, logical, or a combination thereof. In contrast, when an element is referred to as being "directly coupled to" or "directly connected to" another element, it means that there are no intervening elements present between the two.
Unless the context clearly requires otherwise, the words "comprise," "comprising," and the like in the description are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, it is the meaning of "including but not limited to".
In the description of the present invention, it should be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Furthermore, in the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.
In the O-RAN protocol architecture, the O-RU is used as an independent network element and is subordinate to the O-DU and can be managed by a plurality of O-DUs. Physically, the O-DU and the O-RU may be directly connected or connected through a router.
In general, O-RUs can be classified into single-system O-RUs and multi-system O-RUs. When the O-RU only receives and transmits one network type of data, the O-RU is called a single type O-RU; when an O-RU is capable of transceiving multiple network-type data, the O-RU is referred to as a multi-type O-RU. In addition, the O-DUs may be configured to process only one network format data, and may also be configured to process multiple formats of data. The O-DU referred to in the present invention generally refers to a single-system O-DU that processes only one network-system data. The network system is defined by the data type transmitted between the O-RU and the O-DU, for example, if GSM network data is transmitted between the O-RU and the O-DU in the 2G network, the system of the O-RU is GSM, and if WCDMA network data is transmitted between the O-RU and the O-DU in the 3G network, the system of the O-RU is WCDMA. Among them, the network system includes, but is not limited to: global system for mobile communications (Global System for Mobile Communications, abbreviated GSM), time Division-synchronization code Division multiple access (tdscdma) system (Time Division-Synchronous Code Division Multiple Access, abbreviated CDMA 2000), code Division multiple access2000 (Code Division Multiple Access, abbreviated CDMA 2000), wideband code Division multiple access (Wideband Code Division Multiple Access, abbreviated WCDMA), long term evolution (Long Term Evolution, abbreviated TD-LTE) supporting TDD mode, long term evolution (Long Term Evolution, abbreviated LTE-FDD) supporting FDD mode, and 5G NR (New Radio).
Fig. 2 is a flow chart of a service communication method according to an embodiment of the present invention. The service communication method provided by the embodiment of the invention is applied to the O-RU, and specifically as shown in fig. 2, the method comprises the following steps:
step S210: and starting a plurality of application instances according to the local system configuration when the O-RU is initialized, wherein each application instance comprises an O-RAN protocol processing process and a network type service processing process.
The initialization process of the O-RU generally occurs when the O-RU is powered on or reset to restart, and the initialization process relates to the whole flow from the starting to the restarting of the O-RU to the service providing of the business.
The difference from the prior art O-RU initialization is: the present invention introduces the operation of "starting multiple application instances" during the initialization phase. The "application instance" herein is a communication object when an O-DU performs service communication with an O-RU, and one O-DU corresponds to performing service communication with the O-RU through one application instance started on the O-RU. Each application instance includes an O-RAN protocol processing procedure and a network-based service processing procedure, that is: each application instance is actually a set of processes, and the processes are classified into processes responsible for O-RAN protocol processing and processes associated with network-based service processing, where the O-RAN protocol processing processes include O-RAN protocol related functional interfaces and processes that are required to be implemented on the O-RU side and specified by the O-RAN protocol, and are different from the O-RAN protocol processes included in the O-RU in the conventional technology: the O-RAN protocol processing procedure included in each application instance in the present invention does not include specific operations related to the service, such as: in the prior art, after the carrier establishment service is issued to the O-RU by the O-DU, the O-RAN protocol part in the O-RU directly performs processing to complete the service, while the O-RAN protocol in the application example of the present invention is not responsible for completing the specific service operation, that is: the whole carrier establishment flow is carried out by forwarding specific services to a network type service processing process in an application instance, and then the network type service processing process is matched with other specific service processing services (such as carrier management service) to complete the whole carrier establishment flow. Namely: in the invention, specific business operation is stripped from the application examples to form a public business processing service set, so that the processing of the application examples and the specific business service is decoupled, and the implementation of the specific business is not affected by downtime of any application example.
In addition, each application instance only includes a service processing process of a network system, for example: the service processing process only comprises 5G NR or the service processing process only comprises GSM, and the service processing between each network system is processed through different application examples so as to be isolated and mutually noninterfered, namely: the application instance of 5G NR is only responsible for handling 5G NR traffic, the application instance of GSM is only responsible for handling GSM traffic, whereas the O-RU in the prior art only deploys one O-RAN protocol, namely: the O-RAN protocol and the business processing processes of all network modes are integrated together, so that the isolation between the applications of different network modes is not facilitated, and the decoupling of the O-RAN protocol and the applications of different network modes is not facilitated. It should be noted that: the network type service processing process contained in each application example is only completed by carrying out specific analysis on the service issued by the O-DU and forwarding the service to the specific service processing service in the public service processing service set independent of the application example, and the operation of the specific service is not carried out, so that the mode of combining different network type applications and the O-RAN protocol into a single example completely isolates the interference between the applications. In addition, by extracting the public service, the O-RAN protocol in each application example is only focused on the interface to work, and the specific realization of the service is put in the public service to be processed, so that the decoupling between the specific processing of the service with different network systems and the O-RAN protocol is truly realized.
And at the beginning of O-RU design, carrying out system configuration on the number of O-DUs and the network system thereof which are supported by the O-RU according to the system capacity and the network planning of the O-RU. For example, according to network planning, the O-RU is required to support three network systems of 5G NR, TD-LTE and WCDMA at the same time, in this case, in addition to supporting the three network systems on its hardware, the O-RU is also required to support the three network systems on system software, namely: for each network system, at least one application instance corresponding to the network system is started, and as described above, if the O-RU supports three network systems of 5G NR, TD-LTE and WCDMA at the same time, at least three application instances corresponding to each network system need to be started by the O-RU during initialization. Here, the network formats supported by the launched application instances may be the same. For example, as shown in fig. 3, assuming that the O-RU starts two application instances supporting 5G NR, one application instance supporting TD-LTE, and two application instances supporting WCDMA, in this case, the O-RU may support two O-DUs of the 5G NR system, one O-DU of the TD-LTE system, and two O-DUs of the WCDMA system together to make service communication with its connection. The method comprises the steps that an O-DU of one 5G NR system is connected with one 5G NR application instance started on an O-RU to conduct business communication, an O-DU of the other 5G NR system is connected with the other 5G NR application instance started on the O-RU to conduct business communication, an O-DU of a TD-LTE system is connected with a TD-LTE application instance started on the O-RU to conduct business communication, an O-DU of one WCDMA system is connected with one WCDMA application instance started on the O-RU to conduct business communication, and an O-DU of the other WCDMA system is connected with the other WCDMA application instance started on the O-RU to conduct business communication.
In a specific implementation, in a specific example, the O-RAN protocol processing procedures in application instances of different network formats may be identical, that is, a complete set of O-RAN protocol functions, or the O-RAN protocol processing procedures in each application instance may be tailored to a minimum set of network formats according to different network formats, for example: the 5G NR application instance uses more O-RAN protocol processing functions than GSM, so the 5G NR application instance performs relatively more functions than the O-RAN protocol processing procedures in the GSM application instance.
Step S220: when the O-RU performs service communication with a plurality of O-DUs, an application instance in the plurality of application instances and one O-DU in the plurality of O-DUs independently perform service communication, wherein the network system of a service processing process contained in the application instance is the same as the network system of the one O-DU.
Through the above step S210, the O-RU locally starts a plurality of application instances, and after the start is completed, the O-RU is in a ready state and waits for the O-DU to connect to the O-RU for service communication.
According to the O-RAN protocol, the Netconf/Yang management message is transferred between the O-RU and the O-DU, and the message interaction flow of the O-RAN is followed, so that the O-RU and the O-DU need to establish O-RAN Netconf connection before carrying out service communication, and one O-DU carries out the communication object of O-RAN Netconf connection on the O-RU side, namely an application instance, and the system of the O-DU needs to be the same as the network system of the service processing process contained in the application instance which establishes connection with the O-RU, namely: the O-DUs of the 5G NR can only be connected to the application instance handling the 5G NR service and not to the application instance handling the GSM service.
It should be noted that: the application examples started on the O-RU are in one-to-one correspondence with the O-DUs, after a connection is established between one application example and one O-DU, if another O-DU tries to connect with the application example, the connection is refused and cannot be established with the O-DU, namely: an application instance can only be connected with one O-DU at the same time, even if two O-DUs are of the same network type, the application instance cannot be connected with one application instance at the same time, and only after one O-DU is released to be connected, the O-DU of the same network type can be connected with the other O-DU. Likewise, one O-DU cannot connect two application instances at the same time, even if the network systems of the two application instances are the same.
Specifically, based on that an application instance in the plurality of application instances and an O-DU in the plurality of O-DUs independently perform service communication, as shown in fig. 4, the method specifically includes the following steps:
step S2210: the application instance establishes an O-RAN Netconf connection with the one O-DU based on the O-RAN protocol processing procedure it contains.
NETCONF is the Client/Server mechanism. In the O-RAN architecture, the O-DU is a Netconf client, the O-RU is a Netconf server, from the point of view of network deployment location, the O-RU is at a far end, and needs to initiate a process of a Call Home, namely, the O-RU actively initiates a process of a TCP connection request, and notifies the O-DU through a TCP port number, so that the O-DU can asynchronously notify that the O-DU is started and ready, the O-RU calls the Home through the TCP, and then the O-DU establishes SSH/TLS secure connection with the O-RU through a user name password or a certificate, thereby establishing the O-RAN Netconf connection. In addition to the O-RU actively calling the O-DU to establish the O-RAN Netconf connection, the O-DU may also actively call the O-RU to establish the O-RAN Netconf connection. And the establishment of the O-RAN Netconf connection is realized by the O-DU based on the O-RAN protocol processing process contained in an application instance on the O-RU.
Step S2220: the application instance is connected with the O-DU through the O-RAN Netconf and carries out service communication with the O-DU based on the network type service processing process contained in the application instance.
After the O-RAN Netconf connection is established through the above step S2210, at this time, the O-RU and the O-DU may perform the interaction of the Netconf message based on the established O-RAN Netconf connection.
As described above, the network-based service processing procedure included in the application instance is not responsible for executing a specific service, but needs to cooperate with a specific public service processing service in the public service processing service set independent of the application instance to complete a specific service process issued by the O-DU.
Specifically, the application instance is connected through the O-RAN Netconf and performs service communication with the O-DU based on a network-based service processing procedure included in the application instance, as shown in fig. 5, and specifically includes:
step S2221: after the O-DU transmits the service message to the O-RAN protocol processing process in the application example through the O-RAN Netconf connection, the O-RAN protocol processing process in the application example forwards the service message to the network type service processing process for analysis.
Step S2222: and then the network type service processing process in the application example notifies the public service processing service corresponding to the service message in the public service processing service set to process the service message through the request message.
Step S2223: and the public service processing service corresponding to the service message feeds back the processing result of the service message to the network type service processing process in the application example.
Step S2224: and the network type service processing process in the application example forwards the processing result to the O-RAN protocol processing process in the application example.
Step S2225: the O-RAN protocol processing procedure in the application example feeds back the received processing result to the O-DU.
Wherein the common set of business processing services includes, but is not limited to: software management service, DHCP management service, alarm management service, carrier management service, log management service, tone management service and status management service. With the development of mobile network technology, the O-RU may support more business processing services in the future, and the newly added business processing services are also suitable for the invention.
In a specific example, assume that an O-RU initiates 3 application instances, namely, a 5G NR application instance, a GSM application instance, and a TD-LTE application instance, upon initialization, and three O-DUs that can be connected to the O-RU support 5G NR services, GSM services, and TD-LTE services, respectively. Taking the example that an O-DU supporting 5G NR service builds a carrier on an O-RU, firstly, the O-DU builds O-RAN Netconf connection with a 5G NR application instance on the O-RU, then, the O-DU transmits a service message for building the carrier to an O-RAN protocol processing process in the 5G NR application instance through the O-RAN Netconf connection, and then, the O-RAN protocol processing process in the 5G NR application instance forwards the service message to a network type service processing process therein for analysis; then, the network type service processing process in the 5G NR application example notifies the carrier management service in the public service processing service set in the O-RU to process the carrier establishment service message through the request message; after the processing is completed, the carrier management service feeds back the processing result of the carrier establishment service message to a network type service processing process in the 5G NR application example; the network type service processing process in the 5G NR application example forwards the processing result to the O-RAN protocol processing process in the 5G NR application example; the O-RAN protocol processing procedure in the 5G NR application example feeds back the received processing result to the O-DU. Thus, a complete carrier establishment business process is completed.
In addition to the O-DU delivering service to the O-RU, the service communication between the O-DU and the O-RU also includes the O-RU reporting the generated service data to the O-DU, which is also performed by a specific application instance. Specifically, the application instance performs service communication with the O-DU through the O-RAN Netconf connection and based on a network-based service processing procedure included in the application instance, and specifically further includes:
after a public service processing service in the public service processing service set in the O-RU generates service data, reporting the service data to a network type service processing process in the application instance; the network type service processing process in the application example reports the service data to an O-DU through the O-RAN protocol processing process in the application example and based on the O-RAN Netconf connection established between the O-RU and the O-DU. Thus, a complete data reporting process is completed.
As can be seen from the above steps, in the embodiment of the present invention, when an O-RU is initialized, a plurality of application instances are started according to a local system configuration, where each application instance includes an O-RAN protocol processing procedure and a network-based service processing procedure; when the O-RU and the O-DUs carry out service communication, an application instance in the application instances and an O-DU in the O-DUs independently carry out service communication, wherein the network system of the service processing process contained in the application instance is the same as the network system of the O-DU, and because each O-DU carries out service communication with the O-RU through a single application instance, the service processing of each network system is thoroughly isolated through the instance, the operation independence of each O-DU on the O-RU is realized, and the mutual interference is not realized, so that no matter the configuration issuing or the data reporting is completely isolated and not interfered when the O-DU side is operated, the hidden safety hazards and unauthorized access risks are avoided, and the anti-interference performance of service data is improved.
