Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a communication method, a communication device, and a base station. Background Art

[0002] Distributed base stations divide traditional macro base station equipment into two functional units according to their functions: the baseband unit (BBU) and the remote radio unit (RRU).

[0003] Currently, when the main control board (MCB) in a distributed base station needs to be replaced, hardware installers typically need to bring the new MCB to the computer room where the BBU is located. They first remove the old MCB (which may be a faulty MCB or one that doesn't meet performance requirements), then install the new MCB and perform hardware debugging. Furthermore, software installers (also known as site commissioning personnel) are required to bring site commissioning equipment, such as portable or smart terminals, to the computer room where the BBU is located to complete the site commissioning. This indicates that the existing site commissioning technology has high labor costs, requires a lot of time, and has a complex process. Summary of the Invention

[0004] In view of this, the present application provides a communication method, a communication device, and a base station, which can reduce the cost of station deployment and shorten the time required for station deployment.

[0005] In a first aspect, embodiments of the present application provide a communication method that can be performed by a base station, a baseband unit (BBU) in a base station, a main control board (SBC) in a base station, or a module (e.g., a chip) in a base station. The method includes: obtaining channel information from one or more of a baseband board, a remote control unit (RRU), or an automated user automation (AAU); and establishing a channel between a base station and a network management device based on the channel information. The base station includes one or more of the baseband board, the RRU, or the AAU.

[0006] Based on this solution, channel information can be automatically obtained from one or more of the baseband board, RRU or AAU, and a channel can be automatically established between the base station and the network management equipment based on the channel information, thereby reducing the cost and time required for site deployment.

[0012] Based on this solution, it is possible to automatically obtain site deployment information from one or more requests in the RRU or the AAU, thereby reducing site deployment costs and shortening the time required for site deployment.

[0040] Distributed base stations divide traditional macro base station equipment into two functional units: the BBU and the RRU. The BBU primarily performs baseband signal processing (such as channel encoding and decoding, modulation and demodulation), provides transmission management and interfaces, manages wireless resources, and provides clock signals. The RRU primarily performs intermediate frequency signal processing (such as digital in-phase / quadrature (I / Q) modulation and demodulation, up- and down-conversion, and digital-to-analog / analog-to-digital conversion), RF processing, and duplexing.

[0041] A BBU identifier may refer to any identifier that corresponds to the BBU, such as an equipment serial number (ESN). The BBU identifier may be assigned by a network management device or generated by the BBU itself according to preset rules. An RRU identifier may refer to any identifier that corresponds to the RRU, such as an ESN. The RRU identifier may be assigned by a network management device or generated by the RRU itself according to preset rules.

[0042] A single BBU can support multiple RRUs. A multi-channel BBU+RRU solution effectively addresses indoor coverage in large venues. Fiber optic transmission is used between the BBU and RRUs, while the RRUs connect to the antennas via coaxial cables. This means the backbone uses fiber optics, while the branches use coaxial cables.

[0043] To reduce the amount of equipment and patch cables required on the tower, an active antenna unit (AAU) was designed. The AAU integrates the RRU and antenna, thus integrating the functions of both the BBU and the antenna. Fiber optic transmission is also used between the BBU and the AAU.

[0044] Figure 1A BBU can be connected to one or more RRUs (two RRUs are used as an example in the figure) and / or one or more AAUs (two AAUs are used as an example in the figure).

[0045] It should be noted that in the embodiments of the present application, the distributed base station may also be referred to as a base station.

[0046] BBUs come in two forms: frame-type BBUs and box-type BBUs. Figure 2 This diagram shows a modular BBU network. A modular BBU primarily consists of one or more master control and transmission boards (MCHs) and one or more baseband boards (BCHs). The RRUs / AAUs connect to the baseband boards, and the BBU connects to the backhaul network through the MCHs. Figure 3 This is a diagram of a box-type BBU network. The box-type BBU is a single box or board that includes the BBU main control, transmission, and baseband functions. It is also called a main control, baseband, and transmission board.

[0047] The BBU described later in the embodiments of the present application can be a frame-type BBU or a box-type BBU. In the embodiments of the present application, the main control transmission board and the main control baseband transmission board are collectively referred to as the main control board.

[0048] In order to reduce the cost and time required for site opening, an embodiment of the present application provides a site opening method, which can automatically complete the site opening work after the hardware installer completes the replacement of the main control board.

[0049] For ease of explanation, in the embodiment of the present application, the main control board before replacement is referred to as the first main control board or the old main control board, and the main control board after replacement is also referred to as the second main control board or the new main control board.

[0050] A channel must be established between the base station and the network management device. The network management device can use this channel to install or update software or configure files for the base station. The network management device here can be, for example, an operation, administration, and maintenance (OAM) device. The channel between the base station and the network management device can be between the base station's BBU and the network management device, between the base station's RRU and the network management device, between the base station's AAU and the network management device, or between the base station's main control transmission board and the network management device.

[0051] The following describes the site deployment method provided by the embodiments of the present application. It should be noted that the site deployment method provided by the embodiments of the present application can be executed by a base station, a base station bus (BBU) within a base station, or a main control board within a base station. For ease of explanation, the following description uses the main control board as an example of the site deployment method.

[0052] Figure 4 This is a schematic diagram of a communication method, which mainly includes the following operations.

[0053] Operation 401: The first main control board obtains channel information between the base station and the network management device.

[0054] For example, after the channel between the base station and the network management device is successfully established, the first main control board obtains the channel information between the base station and the network management device from the configuration data of the BBU.

[0055] The channel information is used to indicate the channel between the base station and the network management device, and includes one or more of the following information: the Internet Protocol (IP) address of the BBU, the identifier of the virtual local area network (VLAN) (VLAN ID), or routing information.

[0056] The routing information includes the next-hop routing IP address of the BBU and the IP information of the network management device. The IP information of the network management device includes the IP address of the network management device or the IP network segment of the network management device. As an example, the IP network segment of the network management device is 10.10.10.1 / 24, where / 24 represents the first 24 bits of 10.10.10.0, that is, 10.10.10, which is the subnet identifier. Therefore, the IP addresses indicated by 10.10.10.1 / 24 include: 10.10.10.1~10.10.10.254. By configuring the route of a network segment instead of configuring the route of each IP address one by one, routing entries can be saved. In the embodiment of the present application, the next hop of the BBU can be understood as the next hop of the base station.

[0057] As an implementation method, if the BBU actively connects to the network management device as a client, that is, the BBU actively initiates the connection to the network management device, the channel information may include the IP information of the network management device.

[0058] As an implementation method, if the network management device actively connects to the BBU, that is, the network management device actively initiates the connection to the BBU, the above-mentioned channel information may not include the IP information of the network management device.

[0059] As an implementation method, if the above-mentioned channel includes an Internet Protocol Security (IPsec) tunnel, the above-mentioned channel information may also include one or more of the following information: an IP address of a security gateway, a security algorithm, or an IP address of a Certificate Authorities (CA).

[0060] Figure 5This is a schematic diagram of replacing a main control board. The channel information between the first main control board and the network management device includes:

[0061] BBU IP address: IP1;

[0062] VLAN ID: 10;

[0063] Routing information: The next-hop routing IP address of the BBU is IP2, and the IP address of the network management device is IP3.

[0064] Operation 402: The first main control board saves the acquired channel information to one or more of the baseband board, RRU or AAU.

[0065] That is, the first main control board sends channel information to one or more of the baseband board, RRU or AAU.

[0066] As an implementation method, when the first main control board is a baseband transmission board of a frame-type BBU, the first main control board can save the channel information to a baseband board.

[0067] As an implementation method, when the first main control board is the baseband transmission board of a frame-type BBU, the first main control board can save channel information to multiple baseband boards, and the multiple baseband boards store the same channel information. This method uses a multi-backup mechanism to back up a single channel information multiple times.

[0068] As an implementation method, when the first main control board is the baseband transmission board of a frame-type BBU, the first main control board can save channel information to multiple baseband boards, and each of the multiple baseband boards will save part of the channel information. This method disperses the channel information across multiple baseband boards, thereby reducing the amount of data required to be saved by each baseband board and does not increase the storage pressure on each baseband board.

[0069] As an implementation method, the first main control board saves the channel information to one or more RRUs. The specific implementation method can refer to the implementation method of saving the channel information to one or more baseband boards, which will not be repeated here.

[0070] As an implementation method, the first main control board saves the channel information to one or more AAUs. The specific implementation method can refer to the implementation method of saving the channel information to one or more baseband boards, which will not be repeated here.

[0071] As an implementation method, the first main control board saves the channel information to one or more baseband boards and one or more RRUs, or saves the channel information to one or more baseband boards and one or more AAUs, or saves the channel information to one or more RRUs and one or more AAUs, or saves the channel information to one or more baseband boards, one or more RRUs, and one or more AAUs. The specific implementation method can refer to the implementation method of saving channel information to one or more baseband boards, and will not be repeated here.

[0072] Optionally, in operation 402, the first main control board may also save the identifier of the BBU corresponding to the channel information to one or more of the baseband board, RRU, or AAU. Associating the channel information with the BBU helps avoid incorrect use of the channel information.

[0073] In actual situations, the main control board may need to be replaced. The hardware installer brings the second main control board to the computer room where the BBU is located, first removes the first main control board, and then installs the second main control board. Figure 6 This is a schematic diagram of another communication method, which mainly includes the following operations.

[0074] Operation 601: The second main control board obtains channel information from one or more of the baseband board, RRU or AAU.

[0075] After the second main control board is installed, it can be started using its onboard software, placing it in a ready-to-start state. It then establishes a communication connection with one or more of the baseband board, RRU, or AAU. This allows the second main control board to obtain channel information from one or more of these baseband boards, RRUs, or AAUs. This channel information is the same as the channel information stored by the first main control board.

[0076] Specifically, when the second main control board is a baseband transmission board of a frame-type BBU, the second main control board can obtain channel information from one or more of the baseband board, RRU, or AAU of the frame-type BBU. When the second main control board is a box-type BBU, the second main control board can obtain channel information from one or more of the RRU or AAU.

[0077] Operation 602: The second main control board establishes a channel between the base station and the network management device according to the channel information.

[0078] Optionally, in operation 601, the second main control board may further obtain an identifier of the BBU corresponding to the channel information from one or more of the baseband board, RRU, or AAU, so that the second main control board can determine whether the obtained channel information is available based on the obtained BBU identifier. For example, the second main control board determines whether the BBU identifier corresponding to the obtained channel information is the same as the BBU identifier obtained from the BBU hardware (i.e., the BBU identifier of the base station). If they are the same, it indicates that the channel information is available; otherwise, it is unavailable.

[0079] by Figure 2 Taking the frame-type BBU structure shown as an example, before replacing the main control transmission board, the first main control board saves the channel information and BBU identification to the baseband board 1 and the baseband board 2. For example, the baseband board 1 and the baseband board 2 store the same information, specifically: (channel information a, BBU ID-1). Among them, BBU ID-1 is the identification of the BBU 1 where the first main control board is located. Subsequently, the baseband board 1 is replaced. For example, the hardware installer disassembles the baseband board 1 and installs a baseband board on the BBU 2, hereinafter referred to as baseband board 7, in the position where the baseband board 1 is located, that is, Figure 2 Baseband board 1 is replaced with baseband board 7. Furthermore, baseband board 7 stores the channel information corresponding to BBU-2 and the BBU-2 identifier, specifically (channel information b, BBU ID-2). Subsequently, when the first main control transmission board is replaced with a second main control board, the second main control board obtains channel information b and BBU ID-2 from baseband board 7, and obtains BBU ID-1, the BBU1 identifier, from BBU 1's hardware. The second main control board determines that the BBU identifier (i.e., BBU ID-2) obtained from baseband board 7 is different from the BBU identifier (i.e., BBU ID-1) obtained from BBU 1's software and / or hardware. It then determines that the channel information b obtained from baseband board 7 is unusable. This can be understood as the obtained channel information b not corresponding to the base station's BBU. Therefore, the second main control board does not use channel information b to establish a channel with the network management device. This method can avoid using incorrect channel information for channel establishment.

[0080] Subsequently, the second main control board can continue to obtain channel information and BBU identifiers from baseband board 2. Specifically, it obtains channel information a and BBU ID-1. The second main control board then determines that the BBU identifier (i.e., BBU ID-1) obtained from baseband board 2 is the same as the BBU identifier (i.e., BBU ID-1) obtained from the hardware of BBU 1. It then determines that channel information a obtained from baseband board 2 is usable. It can be understood that the obtained channel information a is the channel information corresponding to the BBU of the base station. Therefore, the second main control board uses this channel a to establish a channel with the network management device.

[0081] Optionally, the following operations 603 and 604 are also included.

[0082] Operation 603: The second main control board obtains station deployment information, which includes one or more of the following information: software information, configuration files, or license files.

[0083] As an implementation method, the second main control board can obtain the site opening information from the network management device. For example, the second main control board sends a first request to the network management device to obtain the site opening information, and then the network management device sends the site opening information to the second main control board based on the first request.

[0084] As another implementation method, if the site opening information is also saved by the first main control board to one or more of the baseband board, RRU or BBU, the second main control board can obtain the site opening information from one or more of the baseband board, RRU or AAU. For example, the second main control board sends a second request to one or more of the baseband board, RRU or AAU to obtain the site opening information, and then one or more of the baseband board, RRU or AAU sends the site opening information to the second main control board based on the second request. Optionally, when the second main control board can obtain the site opening information from one or more of the baseband board, RRU or AAU, operation 603 can be completed in one operation with the above operation 601, or in two different operations.

[0085] Operation 604: The second main control board performs a station opening operation according to the station opening information.

[0086] The second main control board can install or update the software according to the software information, configure parameters according to the configuration file, and grant permissions according to the license file.

[0087] Through the above operations 601 to 604 , the automatic site opening operation after the main control board is replaced can be implemented, thereby reducing site opening costs and shortening the time required for site opening.

[0088] It should be noted that after the first main control board is replaced with the second main control board, the channel information will be updated. Therefore, the second main control board can also obtain the channel information from the BBU configuration data and save the obtained channel information to one or more of the baseband board, RRU, or AAU. The specific implementation process is similar to the operations of steps 401 to 402 above and will not be repeated here.

[0089] It is understood that, in order to implement the functions in the above embodiments, the base station and the terminal include hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should readily appreciate that, in conjunction with the units and method steps of the various examples described in the embodiments disclosed in this application, this application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in hardware or in a computer software-driven hardware manner depends on the specific application scenario and design constraints of the technical solution.
