Description
Technical Field
The present invention relates to communication technologies, and in particular, to a method and an apparatus for sharing transmission resources in a virtualized base station access network in the field of wireless base station transmission access.
Background
The biggest difference between the traditional Communication Technology (CT) and Information Technology (IT) designs is that CT equipment providers provide a set of solutions with closed software and hardware, which is high in efficiency, but hardware resources are not open to the outside, interoperability is poor, and software of a equipment provider cannot run on a hardware platform of a B equipment provider; the IT equipment business adopts general hardware and an operating system, can adapt to the services of different manufacturers, and divides network management into a hardware management plane (also called out-of-band management) and a service plane due to the diversity of upper-layer software, the equipment business is only responsible for the management of the hardware management plane, and the rest is processed by the service software. Fig. 1 is a schematic diagram of a separation of a service plane and a hardware management plane provided in the prior art, and fig. 2 is a schematic diagram of a difference between the service plane and the hardware management plane of an IT device provided in the prior art and a service plane and a hardware management plane of an edge node CT device, as shown in fig. 1 and fig. 2, the service plane of the IT device uses an Internet Protocol (IP) 1, the hardware management plane uses IP2, and the service plane and the hardware management plane of the edge node CT device use the same IP.
Traditional CT equipment such as base station software and hardware are integrated, version, alarm, transmission, hardware resources and the like are managed in a unified mode, and therefore service software and bottom hardware are coupled deeply. The abnormal operation of the service software may cause the base station to be separated from the network management, and the hardware management (such as power-on, fan, monitoring and the like) should not depend on the service software, so the design of the traditional base station is not reasonable.
Network Function Virtualization (NFV) architecture relates to unified orchestration (or) of hardware Virtualization management, cloud management, and business management. Obviously, the closed software and hardware integrated CT device is not suitable for NFV, so the software and hardware architecture of the CT device needs to be improved in the virtualization management. Although network virtualization is a key Technology for next generation Communication or Information Communication Technology (ICT) convergence, IT originates in the IT field, and introduction of virtualization Technology in the CT field also brings new problems.
Network virtualization technologies such as NFV have originated from Data Centers (DC), which are standardized rooms where a large number of servers are centrally located and interconnected using high-bandwidth networks. Centrally located servers can utilize a large number of internal resources such as power supplies, high performance switches, fiber optics, network ports, IP addresses, etc. However, these internal resources are rather the most scarce resources for the radio base station.
The wireless network needs to support sufficient coverage, most base stations are located at edge nodes relative to a core network, supporting facilities of the edge nodes need to be planned in advance, and smooth upgrade of the network needs to be supported, that is, new equipment needs to utilize a power supply and transmission equipment of old equipment, even an IP address and the like. The wireless network virtualization introduces an independent hardware management plane, which is more convenient and reasonable from the management perspective, but the independent hardware management plane and the service management plane also increase the consumption of resources, such as network ports, optical fibers, IP addresses, and the like. Both the network port and the optical fiber are physical resources, and the wiring needs to be constructed again, which is high in cost. But as the number of access devices increases, the number of IP addresses such as edge node public networks or metropolitan area networks becomes more and more scarce.
The traditional base station only needs 1 network cable, and the base station can be managed by 1 Operation Administration and Maintenance (OAM) IP. The virtualized base station needs at least 2 network lines, and 2 IPs (i.e. service plane management IP and hardware management plane management IP) manage the base station. When an edge node site is replaced, since the IP with the same configuration for the service plane and the hardware management plane simply causes IP collision, how to make the service plane and the hardware management plane of the virtualized base station share the transmission resources of the traditional base station, such as a network port (or an optical fiber), management IP, and the like, that is, opening and operating the virtualized base station by using the existing transmission resources (1 network line and 1 IP, and the like) becomes one of the difficulties to be solved.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described below are only for the purpose of illustrating and explaining the present invention, and are not to be construed as limiting the present invention.
The service software and the hardware management software of the virtualized base station of the present invention are independent of each other, either in hardware or logically, e.g., run on different boards or different cores. Fig. 3 is a schematic diagram of splitting a protocol stack of a service plane and a hardware management plane into a related protocol stack and a general protocol stack according to an embodiment of the present invention, and as shown in fig. 3, splitting a protocol stack of a service plane and a hardware management plane into an application related protocol stack and a general protocol stack, for example, splitting a protocol stack of a service plane into a service application related protocol stack and a service application general protocol stack, and similarly, splitting a protocol stack of a hardware management plane into a hardware management related protocol stack and a hardware management general protocol stack. Then, the direct call interface tightly coupled between the application-related protocol stack and the generic protocol stack is modified into a message or network interface, for example, a message or network interface is used between the service application-related protocol stack of the service plane and the hardware management generic protocol stack of the hardware management plane, and similarly, a message or network interface is used between the service application generic protocol stack of the service plane and the hardware management-related protocol stack of the hardware management plane. The application-related protocol stack includes application-specific processing procedures and protocols, and the general protocol stack generally includes general functions such as IP configuration, routing, data transceiving, and the like.
The network management configures the transmission resources of the service plane and the hardware management plane, and the service module (including the service application related protocol stack and the service application general protocol stack) sends the message to the hardware management general protocol stack of the hardware management module (including the hardware management related protocol stack and the hardware management general protocol stack) through the message or the network interface, and sends the message from the network interface of the hardware management module.

Similarly, the network manager configures the transmission resources shared by the hardware management plane and the service plane, and the hardware management plane sends the message to the service application general protocol stack of the service module through the message or the network interface and sends the message from the network port of the service module. That is, when the hardware management plane has no transmission resource and the service plane has transmission resource, the hardware management plane and the service plane share one set of transmission resource, that is, the hardware management plane uses the transmission resource of the service plane, and at this time, when the hardware management plane sends a message, the hardware management related protocol stack sends the message to the service application general protocol stack through a message or a network interface, so as to send the message using the transmission resource of the service platform.
When receiving message, the network interface sends different types of message to hardware management related protocol stack of hardware management plane and service application related protocol stack of service plane according to registered message type information, then the hardware management related protocol stack and service application related protocol stack are delivered to their upper layer application module.
The shared transmission resources comprise resources such as physical network ports, optical fibers, IP addresses, VLANs and the like.

That is to say, the service plane and the hardware management plane share the transmission resource of the hardware management plane, when the service plane needs to send a message, the service application related protocol stack sends the message to the hardware management general protocol stack through the first message or the network interface, so that the service plane sends the message by using the transmission resource such as the network port of the hardware management plane; when the hardware management plane needs to send the message, the hardware management related protocol stack sends the message to the hardware management general protocol stack, and the hardware management plane sends the message by using the transmission resources such as the network port of the hardware management plane.

That is to say, the service plane and the hardware management plane share the transmission resource of the hardware management plane, and when the message received by the hardware management universal protocol stack by using the transmission resource is the message which needs to be sent to the service plane, the message is sent to the service application related protocol stack through the first message or the network interface, so that the service plane receives the message by using the transmission resource such as the network port of the hardware management plane; when the message received by the hardware management general protocol stack by using the transmission resource is the message which needs to be sent to the hardware management plane, the received message is sent to the hardware management related protocol stack, and the purpose that the hardware management plane receives the message by using the transmission resource of the hardware management plane, such as the network port, is achieved.
When the network manager configures the hardware management plane to use the transmission resource of the service plane, the service plane universal protocol stack receives a message by using the transmission resource of the service plane, and sends the received message to the service plane related protocol stack or to the hardware management related protocol stack through a second message or a network interface according to the type of the received message. That is to say, the service plane and the hardware management plane share the transmission resource of the service plane, and when the message received by the service application common protocol stack using the transmission resource is a message that needs to be sent to the hardware management plane, the message is sent to the hardware management application related protocol stack through a second message or a network interface, so that the hardware management plane receives the message using the transmission resource such as the network port of the service plane; when the message received by the service application general protocol stack by using the transmission resource is the message required to be sent to the service plane, the received message is sent to the service application related protocol stack, so that the service plane receives the message by using the transmission resource such as the self network port.
Fig. 6 is a block diagram of an apparatus for sharing transmission resources in a virtualized base station access network according to an embodiment of the present invention, and as shown in fig. 6, the apparatus includes a first protocol stack splitting module, a second protocol stack splitting module, a service module, and a hardware management module.
The first protocol stack splitting module is used for splitting a protocol stack of a service plane of the virtualized base station into a service application related protocol stack and a service application general protocol stack.
The second protocol stack splitting module is used for splitting a protocol stack of a hardware management plane of the virtualized base station into a hardware management related protocol stack and a hardware management general protocol stack.
The hardware management module is used for sending messages from the service application related protocol stack and the hardware management related protocol stack by using the shared transmission resource through the hardware management general protocol stack, receiving the messages by using the shared transmission resource, and sending the received messages to the service application related protocol stack or the hardware management related protocol stack according to the type of the received messages. Specifically, when the network manager configures the service plane to use the transmission resource of the hardware management plane, the message is sent in the direction, the hardware management general protocol stack of the hardware management module receives the message from the service application related protocol stack through the first message or the network interface, and sends the received message by using the transmission resource thereof, so that the service plane sends the message by using the transmission resource of the hardware management plane; and in the message receiving direction, the hardware management general protocol stack of the hardware management module receives the message by using the transmission resource thereof, and sends the received message to the hardware management related protocol stack thereof or to the service application related protocol stack through a first message or a network interface according to the type of the received message, so that the service plane receives the message by using the transmission resource of the hardware management plane.
The service module is used for sending messages from the service application related protocol stack and the hardware management related protocol stack by using the common transmission resource through the service application general protocol stack, receiving the messages by using the common transmission resource, and sending the received messages to the service application related protocol stack or the hardware management related protocol stack according to the type of the received messages. Specifically, when the network manager configures the hardware management plane to use the transmission resource of the service plane, the message is sent in the direction, and the service application general protocol stack of the service module receives the message from the hardware management related protocol stack through the second message or the network interface, and sends the received message by using the transmission resource thereof, so that the hardware management plane sends the message by using the transmission resource of the service plane; and in the message receiving direction, the service plane general protocol stack of the service module receives the message by using the transmission resource thereof, and sends the received message to the service plane related protocol stack thereof or the hardware management related protocol stack through a second message or a network interface according to the type of the received message, so that the hardware management plane receives the message by using the transmission resource of the service plane.
The service software runs on the service single board, the hardware management software runs on the hardware management single board, and the service software and the hardware management software have independent protocol stacks. The service plane and the hardware management plane split the respective protocol stacks into a processing protocol stack and a general protocol stack related to the application. The service application related protocol stack includes a service specific processing signaling flow and protocol, such as Long Term Evolution (LTE) protocol signaling, Universal Mobile Telecommunications System (UMTS) protocol signaling, and the like. The hardware management application comprises flow operations of fan control, single board power-on, clock and the like. The generic protocol stack typically includes general functions such as IP configuration, routing, ARP, etc. The direct calling interface between the application related protocol stack and the general protocol stack is modified into a message or a network interface. If the network manager configures the service plane and the hardware management plane to share the transmission resource (i.e. the hardware management plane shares the transmission resource to the service plane), the service module sends the configuration message to the general protocol stack of the hardware management module and sends the configuration message from the network port of the hardware management module. Similarly, the network manager configures the hardware management plane and the service plane to share the transmission resource (i.e. the service plane shares the transmission resource to the hardware management plane), and the hardware management module sends the configuration and the message to the general protocol stack of the service module and sends the configuration and the message from the network port of the service module. When receiving message, the network port sends different types of message to the relevant protocol stack of hardware management or the relevant protocol stack of service application according to the registered message type information, and then sends the message to the respective upper application module. The message type information generally includes a MAC address, a VLAN, an IP address, a Protocol (Protocol), a Port (Port), and the like.

Example 1:
when the virtualized base station replaces the traditional base station, the main control board of the traditional base station can be used by the hardware management single board, and the service application runs on the general X86 processor. Generally speaking, a hardware management board is powered on before a service board, and when the service board and a new board to be managed have a requirement for sharing transmission resources, a related solution is as follows:
the LTE base station operates on an LTE protocol single board, such as an LTE main control board, an LTE baseband board and the like; the hardware management plane runs on the hardware exclusive management single board.
2. And splitting the LTE protocol stack and the hardware management protocol stack into a protocol stack and a general protocol stack related to the LTE protocol, and a protocol stack and a general protocol stack related to hardware management. And then redesigning a direct function call interface between a protocol stack related to the LTE protocol and a hardware management general protocol stack as a network communication interface, and redesigning a direct function call interface between a protocol stack related to the hardware management and the LTE general protocol stack as a network communication interface.
3. If the network manager configures the hardware management plane and the common transmission IP of the LTE service (namely, the transmission resource of the LTE service is shared), the protocol stack related to the hardware management sends the message to the LTE general protocol stack through the network communication interface, and the LTE general protocol stack sends the message out from the network port of the LTE related single board.

When receiving the message, the network port of the single board related to the LTE receives the message, distinguishes the message according to the MAC address, the IP and the protocol type, respectively submits different messages to the protocol stack related to the LTE protocol and the protocol stack related to the hardware management, and then respectively submits the different messages to the LTE and the hardware management surface by the corresponding application protocol stack.
Example 2:
for a commercial LTE virtualized base station, if a third-party application is added to a general server, a locally available transmission resource needs to be provided for the third-party application, and similarly, if no independent transmission resource such as an IP can be allocated, the third-party application can only share the transmission resource such as the IP with a service application or a hardware management plane. The relevant solution is as follows:
