Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a baseband pool sharing method, apparatus, and distributed base station system.
Background
In a conventional distributed Base station, a baseband processor (BBU) of the conventional distributed Base station is generally located at the same site as a Remote Radio Unit (RRU), the BBU is generally installed in a machine room or a cabinet and is responsible for baseband data processing of the Base station, and the RRU is generally connected to an antenna through a feeder line and is responsible for Radio frequency and intermediate frequency data processing in an outdoor environment. In this way, the data volume of the RRUs that each BBU can process is limited, generally, one BBU can only connect 3 to 6 RRUs, the BBU size is smaller, and generally, a standard rack width and a height of 1U to 3U are adopted. When the BBU works, systems such as an independent installation environment, a power supply, a storage battery, transmission, monitoring, GPS clock input and the like are needed, the utilization efficiency of the resources is low, the number of devices is large, and system fault points are increased.
With the increasing enhancement of centralized maintenance requirements and more difficulty in site leasing, it is necessary to intensively and uniformly install and arrange baseband data processing equipment, and the current method is to change the installation position of an independent BBU and transfer the BBU from a base station side to a centralized installation machine room, but the structure is not changed in principle, and still a BBU is only responsible for processing the baseband data of an RRU directly connected with the BBU through an optical fiber, and cannot share baseband resources.
Specifically, in terms of the utilization efficiency of baseband resources, since the next BBU is only responsible for processing the baseband data of the RRU directly connected to the BBU through the optical fiber in the conventional manner, the baseband resources between different BBUs cannot be shared, and thus the tidal phenomenon of traffic cannot be solved. For example, during daytime, the traffic of residential areas is low, the baseband data processing capacity of the base station is low, and the hardware resources of the equipment are idle, but the baseband resources cannot be allocated to high-traffic areas such as business areas in daytime. Similarly, the business area has low traffic at night, the baseband data processing capacity is low, and the hardware resources of the equipment are idle, but the baseband resources cannot be allocated to high-traffic areas such as residential areas at night. In order to meet the service index, the devices in different areas must be configured according to the highest traffic, which causes great waste of hardware resources of the devices.
In the aspect of corollary equipment, in order to enable the BBU to work normally, each base station must be provided with a power supply, a storage battery, transmission, monitoring, GPS clock input, an air conditioner and the like. The number of devices is large, and system fault points are increased. Even if the BBU service volume of the equipment is low, the equipment must normally operate, especially the air conditioning equipment never stops, the power consumption is large, and the equipment is the main power of the base station.
In the aspect of installation environment, as the BBU can only be installed in a machine room or a cabinet with environment protection capability generally, a certain installation space needs to be occupied, in order to provide services, a rental machine room is generally needed for placing the BBU and supporting equipment, and the rental cost is high.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Example one
As shown in fig. 1, an embodiment of the present invention provides a baseband pool sharing method, including:
step 10: the base band pool sharing device receives data to be processed sent by a first remote radio unit RRU, and comprises a plurality of base band processing units BBU.
The baseband pool sharing device formed by combining a plurality of BBUs has large data volume computing capability and enough backboard data interaction capability. Each BBU in the same baseband pool sharing device can perform resource sharing, and the baseband pool sharing device can be regarded as a first-stage baseband data processing resource pool.
The first RRU is responsible for transmitting data to be processed, that is, radio frequency or intermediate frequency signals processed by the first RRU, to the baseband pool sharing device through an optical fiber network, where the transmission of the signals may be directly connected by an optical fiber or may be transmitted through a network such as an optical switch.
Step 20: and allocating a first BBU for the data to be processed according to a preset processing strategy, and indicating the first BBU to process the data to be processed.
After receiving the to-be-processed data sent by the first RRU, the baseband pool sharing device allocates a first BBU to the first RRU according to a preset processing policy. The baseband pool sharing device can allocate resources according to the setting of the network management system, and process the data to be processed from the RRU. When processing data to be processed, any BBU can be used, for example, a BBU with higher priority using idle resources, a specific hardware resource allocation mode or autonomous or manual selection by a network manager.
Step 30: and obtaining a processing result of the data to be processed after being processed by the first BBU, and feeding back the processing result to the first RRU or the core network side.
The first BBU processes the data to be processed to obtain a processing result, and the baseband pool sharing device feeds back the processing result to the first RRU, or transmits the processing result to a base station controller or a core network side, where the transmission of the signal may be optical fiber direct connection, or may be performed through a network formed by an optical switch, for example.
In this embodiment, a large-capacity baseband pool sharing device is formed by using a plurality of baseband processing units BBUs, which not only improves the data processing capability, but also reduces the storage room of the conventional baseband processor, improves the utilization rate of hardware resources, and reduces the construction cost and the maintenance cost to a certain extent.
Further, the allocating, according to the preset processing policy, the first BBU to the to-be-processed data in step 20 specifically includes:
and determining the current service processing pressure index of each BBU. The service processing pressure index refers to a ratio of the currently processed service volume to the highest service volume of the BBU.
And screening the BBUs with the service processing pressures lower than a preset threshold value in the BBUs according to the service processing pressure indexes to form a BBU set to be allocated. For example: the preset threshold value is 0.8, when a BBU needs to be allocated to a certain data to be processed, the current processing pressure of each BBU needs to be inquired, when the service processing pressure value of a certain BBU is 0.6, the BBU is divided into BBU sets to be allocated, when the service processing pressure value of a certain BBU is 0.9, the BBU is ignored, and other BBUs are re-detected.
And determining one BBU in the BBU set to be allocated as a first BBU, and forwarding the data to be processed to the first BBU. When processing data to be processed, the processing can be performed by any BBU in the baseband pool sharing device, preferably, baseband processing equipment with more idle resources can be preferentially used, and a specific hardware resource allocation mode or autonomous or manual selection by a network manager can be performed
Further, the preset processing strategy mentioned in step 20 can also be performed as follows. When the baseband pool sharing device receives data to be processed sent by a first Remote Radio Unit (RRU), first position information sent by the first RRU is further received;
searching a BBU corresponding to the first RRU according to a pre-established corresponding relationship between the RRUs and the BBU;
detecting whether the service processing pressure of the BBU corresponding to the first RRU is lower than a preset threshold value;
if yes, determining the BBU corresponding to the first RRU as the first BBU;
if not, screening the BBUs with the service processing pressures lower than a preset threshold value in the BBUs according to the service processing pressure indexes of the BBUs to form a BBU set to be allocated; and determining one BBU in the BBU set to be allocated as a first BBU, and forwarding the data to be processed to the first BBU.
Further, when the baseband pool sharing apparatus receives to-be-processed data sent by the first remote radio unit RRU, before the step of further receiving the first location information sent by the first RRU, the method further includes: and storing the corresponding relation between the RRU and the BBU to the local, wherein the corresponding relation between the RRU and the BBU is established according to the position information of the RRU. It should be noted that the above-mentioned method for creating the correspondence between the BBU and the RRU is consistent with the method for creating the correspondence between the BBU and the RRU in the prior art, and therefore, is not described in detail herein.
As shown in fig. 2, in another aspect of the embodiment of the present invention, there is also provided a baseband pool sharing apparatus 1 including:

Thus, the baseband pool sharing apparatus 1 and all RRUs 2 connected thereto only need one clock signal input. The type of the clock input can be freely selected, and various clock input modes such as GPS, Bits, 1588 and the like can be adopted.
When the GPS is used as the clock source, the GPS antenna may be connected to the baseband pool sharing device 1, or may be connected to any RRU 2. When the GPS clock is acquired by the RRU2, the acquired clock information is reported to the baseband pool sharing device 1 by the RRU2 through optical fiber transmission, and then is distributed to all the RRUs 2 by the baseband pool sharing device 1 after being optimized and adjusted.
Each RRU2 can also independently acquire a GPS clock signal if necessary, compare the acquired clock signal with a clock signal provided by the baseband pool sharing device 1, select an optimal clock according to a specific algorithm, provide the optimal clock to the system by the baseband pool for synchronous use, and feed back the comparison result to the network management system for the system operation and maintenance personnel to review.
When the system synchronization is affected due to clock drift caused by the fact that the RRU2 is far away from the baseband pool sharing device 1 or due to transmission quality problems, a clock calibration link can be established between the baseband pool sharing device 1 and the RRU2, so that the remote capability of the RRU2 is improved.
The RRUs 2 in different areas can also use GPS input alone without using a clock provided by the baseband pool sharing device 1, and the specific selection mode can be adjusted automatically or manually by the network manager.

The baseband pool sharing devices 1 of a plurality of independent racks located in the same machine room or in close geographic positions can be connected through optical fibers to form a local area network shape of a mesh, a star, a chain or a hybrid network. The baseband pool of each independent frame can independently process baseband data, and can also process the baseband data processing request of any interface together, and all the baseband data processing devices are combined to form a second-stage baseband data processing resource pool.
In consideration of the problems of actual wiring and transmission modes, the optical fiber transmission of a plurality of RRUs 2 is allowed to converge to a certain first-stage optical switch 3, and then the optical fiber transmission with larger bandwidth is connected to the baseband pool sharing device 1.
