Description
Technical Field

Background
In the prior art, a Base station is composed of a Base Band Unit (BBU) under an iron tower and a Radio Remote Unit (RRU) on the iron tower. The distance between the BBU and the RRU is short, the BBU is responsible for digital signal processing of the base station, and the RRU is responsible for radio frequency receiving and transmitting after digital-analog conversion. In addition, the distributed base station architecture is used as a new wireless access network architecture, the distributed base station is also composed of a BBU and an RRU, the BBU is a device such as a rack and a processing board which are placed in a machine room, and the RRU is a device which is placed outdoors or on the roof by remote placement. In the distributed base station architecture, all or part of baseband processing resources in a BBU set form a baseband resource pool, and the baseband resource pool is subjected to unified management and dynamic allocation, so that the network performance is improved by effectively supporting a cooperative technology while the resource utilization rate is improved and the energy consumption is reduced.
Fig. 1 is a schematic diagram of a conventional distributed base station architecture. The base band resource pool is connected with a plurality of distributed RRUs through high-speed optical fiber interfaces. In a distributed base station architecture, high-speed real-time baseband sampling I/Q (In-phase/Quadrature) signals need to be transmitted between a BBU and an RRU, and In a signal transmission process, the requirement on bandwidth is high, for example, a TD-LTE 8 antenna requires 10Gbps optical transmission bandwidth for a 20MHz single carrier. However, because the signals transmitted between the BBU and the RRU are signals with a fixed rate, the bandwidth allocated between the BBU and the RRU is also a constant transmission bandwidth, and for this situation, if the constant transmission bandwidth meets a higher bandwidth requirement, when the bandwidth requirement is smaller, a phenomenon of wasting the transmission bandwidth may be caused. It can be seen that a constant transmission bandwidth increases the transmission cost and reduces the user experience.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may 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 disclosure to those skilled in the art.
The first embodiment is as follows:
as shown in fig. 2, a flowchart of steps of a method for configuring a transmission rate in a first embodiment of the present invention is shown, and the specific steps are as follows:
step 101, acquiring transmission bandwidth requirement information between a baseband processing unit and a radio remote unit.
In this step, specifically, the transmission bandwidth requirement information between the baseband processing unit and the remote radio unit may be obtained through a signaling sent by the baseband processing unit or the remote radio unit or an instruction sent by the network manager. Specifically, the signaling or the instruction carries the transmission bandwidth requirement information.
Step 102, configuring the transmission rate between the baseband processing unit and the remote radio unit according to the transmission bandwidth requirement information in a packet transmission mode.
In this step, specifically, the transmission rate between the baseband processing unit and the remote radio unit may be configured in a packet transmission manner according to the acquired transmission bandwidth requirement information.
According to the embodiment, according to a packet transmission mode, the transmission rate between the baseband processing unit and the remote radio unit is configured according to the acquired information of the transmission bandwidth requirement between the baseband processing unit and the remote radio unit, so that the transmission rate can be adapted according to the transmission requirement between the baseband processing unit and the remote radio unit, and the problem that the transmission rate between the existing baseband processing unit and the remote radio unit is a fixed rate is solved, so that the problem that the transmission bandwidth is wasted due to the transmission rate of the fixed rate when the bandwidth requirement is small is solved, the transmission cost is reduced, and the user experience is improved.
Example two:
as shown in fig. 3, a flowchart of steps of a method for configuring a transmission rate in a second embodiment of the present invention is shown, and the specific steps are as follows:
step 201, obtaining the transmission bandwidth requirement information between the baseband processing unit and the remote radio unit after the working mode is upgraded.
Specifically, the working mode between the baseband processing unit and the remote radio unit may change according to the real-time change of the service state, and the transmission bandwidth requirement between the baseband processing unit and the remote radio unit may change according to the change of the working mode. Because the service state of the wireless side changes between busy time and idle time, the joint scheduling mechanism between different baseband processing units and radio remote units also changes between busy time and idle time, that is, the working modes of the system where the baseband processing units and the radio remote units are located can be changed according to different service states, that is, the working mode can be triggered to be upgraded according to the set proper condition of the wireless service state, or the working mode can be triggered to be upgraded manually through the network manager. Different working modes enable transmission bandwidth requirements between the baseband processing unit and the radio remote unit to be different, namely the transmission bandwidth requirements between the baseband processing unit and the radio remote unit can be changed in real time according to the working modes, and the transmission bandwidth requirements of the working mode after upgrading are larger than the transmission bandwidth requirements of the working mode before upgrading. In this step, the information of the transmission bandwidth requirement between the baseband processing unit and the remote radio unit after the working mode is upgraded can be obtained.
Specifically, as shown in fig. 4, the schematic diagram is a schematic diagram of different operating modes of a system in which the baseband processing unit and the radio remote unit are located. In fig. 4, different interfaces correspond to different working modes, that is, the left side of the interface 1 is a working mode, the left side of the interface 2 is a working mode, and so on, the left side of the interface 3 and the left side of the interface 4 are respectively a working mode.
In addition, optionally, the transmission rate between the baseband processing unit and the remote radio unit is a packet transmission mode, and the transmission rate may vary with the requirement of the transmission bandwidth between the baseband processing unit and the remote radio unit. Specifically, in a packet transmission mode, a packet transmission device is introduced, and the packet transmission device is used for grouping transmission rates and is respectively connected with a baseband processing unit and a radio remote unit. When the working mode changes, the baseband processing unit or the remote radio unit may send a signaling to the packet transmission device through the control plane, or the network manager sends an instruction to the packet transmission device, at this time, the packet transmission device receives the signaling sent by the baseband processing unit or the remote radio unit, or receives an instruction issued by the network manager, where both the signaling and the instruction carry information on a transmission bandwidth requirement between the baseband processing unit and the remote radio unit after the working mode is upgraded.
Specifically, as shown in fig. 5, a schematic diagram of receiving signaling and instructions for a packet transmission device is shown. As can be seen from fig. 5, the baseband processing unit, the remote radio unit, and the packet transmission device may transmit baseband data through the data plane and transmit signaling through the control plane; meanwhile, the baseband processing unit, the remote radio unit and the packet transmission device can also receive instructions issued by the network manager.
Step 202, according to the transmission bandwidth requirement information between the baseband processing unit and the remote radio unit after the working mode upgrade, attempting to increase the guaranteed information rate between the baseband processing unit and the remote radio unit.
In this step, specifically, when the packet transmission device acquires, through a signaling or an instruction, the transmission bandwidth requirement information between the baseband processing unit and the remote radio unit after the operating mode is upgraded, the packet transmission device may attempt to increase the guaranteed information rate allocated between the baseband processing unit and the remote radio unit, where the transmission rate includes the guaranteed information rate and the peak information rate. In this step, an attempt is made to increase the guaranteed information rate in the transmission rate.
Step 203, determining whether the sum of the guaranteed information rate increased between the baseband processing unit and the radio remote unit and the guaranteed information rates of other wireless devices on the transmission link where the baseband processing unit or the radio remote unit is located exceeds the transmission bandwidth capability of the packet transmission device, if not, entering step 204, and if so, entering step 208.
In this step, it is determined whether the guaranteed information rate can be successfully increased, specifically, it is determined whether a sum of the guaranteed information rate increased by the baseband processing unit and the radio remote unit and the guaranteed information rates of other wireless devices on a transmission link where the baseband processing unit or the radio remote unit is located exceeds the transmission bandwidth capability of the packet transmission device, that is, it is determined whether all the guaranteed information rates on the entire transmission link exceed the transmission bandwidth capability of the packet transmission device. If not, it indicates that the information rate increase between the baseband processing unit and the remote radio unit is successful, i.e. step 204 is entered; if yes, it indicates that the guaranteed information rate between the baseband processing unit and the remote radio unit fails to increase, and step 208 is entered.
In step 204, the guaranteed information rate between the baseband processing unit and the remote radio unit is increased successfully, and then step 205 is performed.
In step 205, when the transmission bandwidth requirement between the baseband processing unit and the remote radio unit meets a preset condition, the guaranteed information rate between the baseband processing unit and the remote radio unit is reduced.
In this step, specifically, a preset condition may be set according to the wireless service state, or the preset condition may be manually set by the network manager, and when the wireless service state reaches the preset condition, it indicates that the wireless service at this time is less than the service after the information rate is successfully increased. Because the transmission bandwidth requirement between the baseband processing unit and the radio remote unit changes according to the state of the wireless service, after the guaranteed information rate between the baseband processing unit and the radio remote unit is successfully increased, whether the transmission bandwidth requirement between the baseband processing unit and the radio remote unit meets the preset condition can be judged, if the transmission bandwidth requirement between the baseband processing unit and the radio remote unit meets the preset condition, the wireless service is less than the service when the guaranteed information rate is successfully increased, and the guaranteed information rate between the baseband processing unit and the radio remote unit is reduced.
Step 206, judging that the guaranteed information rate between the reduced baseband processing unit and the radio remote unit meets the transmission bandwidth requirement between the baseband processing unit and the radio remote unit before the working mode is upgraded, and if the guaranteed information rate between the reduced baseband processing unit and the radio remote unit meets the transmission bandwidth requirement between the baseband processing unit and the radio remote unit before the working mode is upgraded, entering step 207; if not, go to step 205.
In this step, after the guaranteed information rate between the baseband processing unit and the remote radio unit is reduced, it is determined whether the guaranteed information rate between the reduced baseband processing unit and the remote radio unit meets the transmission bandwidth requirement between the baseband processing unit and the remote radio unit before the working mode is upgraded. If yes, it indicates that the reduced guaranteed information rate can completely guarantee the transmission bandwidth before the working mode is degraded, and at this time, step 207 is entered, that is, a signaling or an instruction is sent to the baseband processing unit or the radio remote unit, where the signaling or the instruction carries the degradation information of the working mode of the baseband processing unit or the radio remote unit; if not, it indicates that the reduced guaranteed information rate cannot guarantee the transmission bandwidth before the working mode is degraded, at this time, step 205 is entered, that is, the guaranteed information rate between the baseband processing unit and the remote radio unit is reduced repeatedly according to the preset condition.
Step 207, sending a signaling or an instruction carrying the degradation information of the operating mode of the baseband processing unit or the radio remote unit to the baseband processing unit or the radio remote unit.
In step 208, the guaranteed information rate between the baseband processing unit and the remote radio unit fails to increase, and then step 209 is performed.
Step 209, transmitting the wireless signal through the peak information rate allocated between the baseband processing unit and the remote radio unit, and detecting whether the packet loss rate of the packet transmission device is greater than a preset threshold, if not, entering step 202, and if so, entering step 207.
In this step, after the guaranteed information rate increase between the baseband processing unit and the remote radio unit fails, the packet transmission device can transmit the wireless signal only with the peak information rate allocated between the baseband processing unit and the remote radio unit. Meanwhile, the packet transmission equipment detects whether the packet loss rate is greater than a preset threshold value. If not, it indicates that the transmission network resource is not congested, the upgraded working mode can be maintained, and an attempt to increase the guaranteed information rate between the baseband processing unit and the radio remote unit can be continued, that is, step 202 is performed; if the value is greater than the threshold, it indicates that the network transmission resource is limited, the service is congested, and the transmission resource cannot meet the requirement of the current wireless device working mode, at this time, a signaling or an instruction carrying degradation information of the working mode of the baseband processing unit or the radio remote unit needs to be sent to the baseband processing unit or the radio remote unit, so as to reduce the working mode of the wireless device, that is, step 207 is entered.
In this embodiment, whether to increase the guaranteed information rate allocated between the baseband processing unit and the remote radio unit is determined according to the acquired transmission bandwidth requirement information between the baseband processing unit and the remote radio unit after the working mode is upgraded and according to the resource condition of the packet transmission device, that is, according to whether the guaranteed information rates of all the wireless devices on the whole transmission link exceed the transmission bandwidth capability of the packet transmission device. The embodiment can change the guaranteed information rate distributed between the baseband processing unit and the remote radio unit according to the transmission bandwidth requirement and the resource condition of the packet transmission equipment, and solves the problem that the transmission rate between the existing baseband processing unit and the remote radio unit is constant, thereby solving the problem of transmission bandwidth waste caused by the transmission rate with fixed rate when the bandwidth requirement is small, reducing the transmission cost and improving the user experience.
