Background
In an existing wireless communication system, a structure in which a BBU (Building Base band Unit) and an RRU (Remote Radio Unit) are combined is widely used. Generally speaking, a BBU includes a plurality of baseband processing boards, each having signal processing capabilities of one or more cells.
In order to meet the requirements of energy conservation and environmental protection, under the condition that the communication service is not busy, one or more baseband boards in the BBU can be closed to achieve the aim of energy conservation. Before one or more baseband boards are shut down, the communication traffic (cells) on these baseband boards needs to be migrated to other baseband boards that remain powered up. The current migration scheme mainly switches the RRU data to the baseband board that remains powered on by directly powering off the baseband board. The method has the advantages of simple flow and the defect that the call can be dropped certainly by the terminal. Therefore, when service migration is performed at present, a call service is dropped, so that a call of a terminal user is dropped in a short time.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein.

Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a migration method of a service, it should be noted that the steps shown in the flowchart of the figure may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that here.
Fig. 1 is a flowchart of a service migration method according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
step S102, a cell is newly built on the first baseband board, wherein the configuration of the newly built cell is the same as that of the cell to be migrated, and the cell to be migrated is a cell running the service to be migrated.
The service to be migrated may be a call service. In order to migrate the service to be migrated to the first baseband board, a new cell is first created on the first baseband board, and the configuration of the new cell is the same as that of the cell to be migrated.
Specifically, the configuration may include information such as a frequency point, a bandwidth, and a PCI (Physical Cell Identifier) of the Cell to be migrated. One or more cells to be migrated may be provided. If the first baseband board has a cell to be migrated, newly building a cell on the first baseband board; and if the base band board has a plurality of cells to be migrated, newly building a plurality of corresponding cells on the first base band board.
The first baseband board and the baseband board where the service to be migrated is located may belong to the same BBU. On the same BBU, the baseband board with the largest traffic volume may be used as the first baseband board.
Fig. 2 is a schematic diagram of a BBU + RRU structure according to an embodiment of the present invention, and as shown in fig. 2, in this example, the baseband board a and the baseband board B may be disposed on the same hardware board. The base band board a is assumed to be a first base band board, and the cell to be migrated is a cell B, which originally runs on the base band board B. The migration task is to migrate the cell B running on the baseband board B to the baseband board a, so a cell is newly built on the baseband board a at first, and the configuration of the cell is completely the same as that of the cell B to prepare for subsequent service migration.
And step S104, controlling the first baseband board and the second baseband board to receive downlink data and control information of the cell to be migrated, and controlling the first baseband board and the second baseband board to receive uplink data of the cell to be migrated, wherein the second baseband board is the baseband board where the cell to be migrated is located.
Specifically, the downlink data and the control information come from a higher layer protocol stack (RRL/RLC/MAC). The control information is control information sent by a base station to a UE (User Equipment), and may include uplink and downlink resource allocation information, HARQ (Hybrid Automatic Repeat reQuest) information, power control information, and the like. The uplink data is IQ antenna data from an RRU corresponding to the second baseband board, and the RRU receives the antenna data of the user terminal to form the uplink data.
Still taking fig. 2 as an example, after a cell B is newly established on a baseband board a, the baseband board a and the baseband board B jointly receive control information and downlink data about the cell B from a higher-layer protocol stack, and the baseband board a and the baseband board B jointly receive uplink data from an RRU B. Therefore, when the baseband board B is not powered off, the uplink data, the downlink data and the control information of the cell B to be migrated are received by the baseband board a and the baseband board B together.
Obviously, with the above scheme, when the second baseband board is not powered off, the uplink data, the downlink data and the control information of the cell to be migrated from the higher-layer protocol stack are all received by the first baseband board and the second baseband board together. At this time, since the second baseband board is not powered off, the downlink data (IQ antenna data) transmitted from the baseband board to the user terminal may be continuously transmitted by the second baseband board or may be transmitted by both the first baseband board and the second baseband board.
And S106, disconnecting the second baseband board from the corresponding radio remote unit.
In an optional embodiment, after a preset time after the first baseband board completes the new cell, the connection between the second baseband board and the corresponding radio remote unit may be disconnected, so that the first baseband board may independently process the service to be migrated.
After the connection between the second baseband board and the corresponding radio remote unit is disconnected, the second baseband board does not process the service any more, but the first baseband board processes the service to be migrated, that is, the first baseband board receives downlink data and control information from a cell to be migrated in a higher layer protocol stack, the first baseband board receives uplink data from the cell to be migrated in an RRU, and the first baseband board sends the downlink data to the user terminal through the RRU.
Still referring to fig. 2, the baseband board B disconnects the connection with the RRU B, and the baseband board a sends downlink data to the user terminal through the RRU B.
Therefore, in the above embodiment of the present application, a cell is newly created on the first baseband board, where the configuration of the newly created cell is the same as that of a cell to be migrated, and the cell to be migrated is a cell running a service to be migrated; controlling the first baseband board and the second baseband board to receive downlink data and control information of a cell to be migrated, and controlling the first baseband board and the second baseband board to receive uplink data of the cell to be migrated, wherein the second baseband board is a baseband board where the cell to be migrated is located; and disconnecting the second baseband board from the corresponding radio remote unit. In the above scheme, after the service migration is determined, before the second baseband board is disconnected from the remote radio unit, a cell with the same configuration is newly built on the first baseband board, and the first baseband board is controlled to receive uplink and downlink data and control information corresponding to the service to be migrated, so that the first baseband board can process the service to be migrated. Meanwhile, the second baseband board is not powered off immediately, but receives uplink and downlink data and control information corresponding to the service to be migrated simultaneously, continues to process the service to be migrated, and then disconnects the second baseband board from the corresponding radio remote unit, so that the service to be migrated is not disconnected in the migration process, and the technical problem that a user is easy to drop calls when the service of the baseband board is migrated in the prior art is solved.
As an alternative embodiment, before newly building a cell on the first baseband board, the method further includes: detecting the load of a plurality of baseband boards in the same indoor baseband processing unit; and when the sum of the loads of the plurality of base band plates is smaller than the load allowed by the single base band plate to operate, determining the base band plate with the highest current load in the plurality of base band plates as a first base band plate and the other base band plates as second base band plates, and entering the step of newly building a cell on the first base band plate.
The above scheme is used to determine when to perform traffic migration. And taking the baseband board with the largest load in the indoor baseband processing unit as a first baseband board, and taking the services on other baseband boards as services to be migrated, and migrating the services to the first baseband board, so that the migrated services are minimized.
In an alternative embodiment, the description is made by taking fig. 2 as an example. As the traffic volume decreases, when the control chip of the BBU detects that the sum of the loads of the baseband board a and the baseband board B is less than the load allowed by the baseband board a, that is, the baseband board a can process all the services on the baseband board a and the baseband board B, since the service on the baseband board B is less than the service on the baseband board a, the service on the baseband board B can be migrated to the baseband board a, so that the baseband board B is powered off to save energy.
It should be noted that there may be one or more second baseband boards, and when the traffic of a plurality of baseband boards is low and one baseband board can handle the traffic, the traffic on the plurality of baseband boards may be migrated.
As an alternative embodiment, before disconnecting the second baseband board from the corresponding remote radio unit, the method further includes: judging whether the first baseband board can demodulate and decode the uplink data of the cell to be migrated; and if the first baseband board can demodulate and decode the uplink data of the cell to be migrated, the step of disconnecting the connection between the second baseband board and the corresponding radio remote unit is carried out.
Specifically, when the first baseband board can demodulate and decode the uplink data of the cell to be migrated, the first baseband board can also process the service to be migrated, and send the processed downlink data to the user terminal through the RRU, so that the connection between the second baseband board and the corresponding remote radio unit can be disconnected at this time.
Still referring to fig. 2, if the uplink direction of the newly-built cell B can be demodulated and decoded correctly on the baseband board a, which indicates that the channel is reliable, the downlink processing result of the baseband board a on the cell B is sent to the RRU B, and the connection between the baseband board B and the RRU B is disconnected.
In the above scheme, under the condition that the first baseband board can demodulate and decode the uplink data of the cell to be migrated, it is indicated that the channel of the service to be migrated constructed by the first baseband board is already reliable, that is, the first baseband board can stably process the service to be migrated, so that the connection between the second baseband board and the corresponding remote radio unit can be disconnected.
As an optional embodiment, when controlling the first baseband board and the second baseband board to both receive the downlink data and the control information of the cell to be migrated, and controlling the first baseband board and the second baseband board to both receive the uplink data of the cell to be migrated, the method further includes: controlling the second baseband board to send the antenna data of the cell to be migrated to the radio remote unit corresponding to the second baseband board; before disconnecting the second baseband board from the corresponding remote radio unit, the method further includes: and controlling the first baseband board to send the antenna data of the cell to be migrated to the second baseband board and the corresponding remote radio unit.
In the above scheme, in the service migration process, the second baseband board still sends the antenna data of the cell to be migrated to the RRU until the second baseband board is disconnected from the corresponding remote radio unit. In the process, when the first baseband board can process the service to be migrated, the first baseband board also sends the antenna data of the cell to be migrated to the RRU, and then the connection between the second baseband board and the corresponding radio remote unit is disconnected, so that the service of the cell to be migrated can be ensured to keep talking all the time.
As an alternative embodiment, after the connection between the second baseband board and the corresponding remote radio unit is disconnected, the method further includes: and controlling the second baseband board to be powered off.
After the second baseband board is disconnected with the corresponding remote radio unit, the second baseband board can be controlled to be powered off, so that the purpose of energy conservation is achieved.
As an alternative embodiment, after the connection between the second baseband board and the corresponding remote radio unit is disconnected, the method further includes: detecting a load of the first base band plate; and if the load of the first baseband board exceeds a preset value, migrating the service on the newly-built cell to a second baseband board, and deleting the newly-built cell.
Since the traffic on one BBU varies in real time, after the traffic on a plurality of baseband boards is migrated to one baseband board as the traffic to be migrated, the traffic on the BBU still needs to be monitored in real time, so as to prevent the traffic from increasing to cause overload on the first baseband board and affect the processing of the traffic.
In particular, the above-mentioned preset value may be the total load allowed to be processed by the first base band plate, or a certain percentage of the total load, for example 90% of the total load. And when the load of the first baseband board exceeds a preset value, migrating the original service path previously migrated to the first baseband board back to the original second baseband board, and deleting the newly-built cell on the first baseband board.
Still taking fig. 2 as an example, in an alternative embodiment, when the load on the base band board a increases to exceed 90% of the total load of the base band board a, the base band board B is controlled to start again, the base band board B is controlled to connect with RRU B, and then the cell B on the base band board a is migrated back to the base band board B.
