Detailed Description
So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.
Fig. 1 is a schematic flow diagram of a base station power saving method according to an embodiment of the present invention, where the base station power saving method of this example is applied to a BBU terminal, and as shown in fig. 1, the base station power saving method includes the following steps:
step 101: and for a set interval, setting the head and tail baseband processing equipment BBUs in the interval to be in an open state.
In the embodiment of the invention, the set interval can be set by a base station manager, the base station generally adopts a chain-shaped networking mode under the scenes of high-speed rails, roads and the like, referring to fig. 5, each BBU is connected with a plurality of RRUs, and the plurality of RRUs cover different road sections and are combined into a cell. For example, each derrick shown in fig. 5 is hung with 2 RRUs, which respectively cover the forward and reverse directions, and 6 RRUs are connected to one BBU and combined into one cell. In general, a section between two stations may be set as a section, and here, a station may be a train station, a car station, or the like.
In the embodiment of the invention, in the set interval, the head BBU and the tail BBU are started for a long time, and the BBU between the head BBU and the tail BBU is initially default to be in a closed state.
Step 102: and the BBU in the on state detects the motion information of the target object through the Radio Remote Unit (RRU) connected with the BBU.
In the embodiment of the invention, for all BBUs in the set interval, initially, the head BBU and the tail BBU are in the on state, and the middle BBU is in the off state. At this time, the head and tail BBUs in the on state detect the motion information of the target object through the RRU connected thereto, where the target object may be a train, an automobile, or the like. The motion information includes at least: whether the target object moves into the cell of the BBU, from which direction the target object enters into the cell of the BBU, and the type of the target object. Here, the types of the objects include a first type object and a second type object, the first type object refers to a train user, an automobile user, or the like, and the second type object refers to a public network user.
Specifically, the BBU in the on state detects whether a target object moves to a cell of the BBU in the on state through a head/tail RRU connected with the BBU;
when the first RRU detects that the target object moves to the cell of the BBU in the open state, determining the moving direction of the target object as a first direction; when the tail RRU detects that the target object moves to the cell of the BBU in the open state, determining the moving direction of the target object as a second direction;
the method comprises the steps that a BBU in an open state determines the time length of a target object moving to a cell of the BBU in the open state through a head RRU and a tail RRU which are connected with the BBU;
and when the time length is less than or equal to the set period time length, determining that the target object is a first type target object.
Referring to fig. 5, when the head RRU of the head BBU, that is, RRU No. 1, detects that a train moves into a cell, it indicates that the train is coming from the left direction, and the moving direction is the right direction, where the first direction is specifically the right direction. When the tail RRU of the tail BBU, that is, RRU No. 6, detects that a train moves into a cell, it indicates that the train is coming from the right, the moving direction is to the left, and the second direction is specifically to the left.
In order to distinguish public network users from train users, two RRUs at the head and the tail of the same cell successively detect user access within a certain time period, and then the train user access is judged; otherwise, the BBU is judged as a public network user, and the BBU is not triggered to be started.
Step 103: and when the motion information of the target object indicates that the target object moves from the first direction to the cell of the BBU in the on state, informing the BBU adjacent to the BBU in the on state to turn on the RRU connected with the BBU.
Referring to fig. 5, when the head RRU of the head BBU, that is, RRU No. 1, detects that a train moves into a cell, it indicates that the train is coming from the left direction, and the moving direction is the right direction, where the first direction is specifically the right direction. The first BBU informs the BBU adjacent to the right side to start the RRU connected with the BBU.
Referring to fig. 5, when the tail RRU of the tail BBU, that is, RRU No. 6, detects that a train moves into a cell, it indicates that the train is coming from the right, the moving direction is left, and the second direction is specifically the left. And the tail BBU informs the left adjacent BBU to start the RRU connected with the tail BBU.
In a preferred embodiment, the BBU adjacent to the BBU in the on state may be notified to turn on all RRUs connected thereto, or a head/tail RRU.
By analogy, when the middle BBU detects that the train enters the cell through the RRU according to the train coming condition, the front-stage BBU in the starting state informs the rear-stage BBU to start the RRU.
In the embodiment of the invention, the running direction of the train is identified by detecting the sequence of the train by the head and tail RRUs, and referring to FIG. 5, taking BBU2 as an example, if the access of a train user is detected from RRU No. 1, the train is judged to run from left to right, and BBU3 is informed to open an RRU radio frequency link. After the BBU3 receives the notification, all RRUs nos. 1 to 6 may be simultaneously turned on, or only RRUs nos. 1 or 6 may be turned on, and when RRU nos. 1 or 6 detect a train user, RRU nos. 2 to 5 are turned on.
In the embodiment of the invention, when the motion information of the target object indicates that the target object moves from the first direction to the cell of the BBU in the on state and the target object is the first type target object, the BBU adjacent to the BBU in the on state is informed to turn on the RRU connected with the BBU.
In a preferred embodiment, the method further comprises: and when the BBU in the closed state does not receive the notice of the adjacent BBU within the preset time period, automatically starting the RRU connected with the BBU.
In the scheme, when the BBU does not receive the starting notice in the direction of a certain level for a certain period of time, the corresponding RRU is automatically and forcibly started, so that the condition that other cells cannot be normally started due to the missed detection or other faults of a certain BBU cell in the middle is avoided, and an automatic starting period can be set according to the train operation time period. For example: and in daytime, when the closing state of the RRU radio frequency link exceeds a certain time but the opening command is not received, the RRU radio frequency link is opened by self to enter a service detection state. When communication between the BBUs fails, normal work of the RRU can be realized, and a fault protection mechanism is provided.
In the embodiment of the invention, X2 interface interaction information is used for informing the BBU adjacent to the BBU in the starting state to start the RRU connected with the BBU. Here, the detection delay is 10ms level, the transmission delay number of the X2 interface is 10ms level, the BBU/RRU information exchange delay is ms level, and the total delay does not exceed 100 ms. The train running distance in the time is less than 10m and far less than the cell coverage distance, so that the condition that the train cannot be started in time does not exist. The notification information can be carried by the custom fields in "eNB configuration update" and "cell activation" in the X2 standard interface.
Step 104: and when the motion information of the target object indicates that the target object moves away from the cell of the BBU in the starting state from the second direction and the BBU in the starting state does not belong to the head/tail BBU, closing the BBU in the starting state.
In the technical scheme of the embodiment of the invention, when the target object moves away from the cell and the BBU of the cell does not belong to the head/tail BBU, the BBU is closed, thereby achieving the effect of power saving. The technical scheme of the embodiment of the invention can close the power amplifier module of the RRU in all downlink time slots in a specific time period aiming at the scene characteristics of chain networking such as high-speed rails, highways and the like, thereby saving more electricity.
Fig. 2 is a schematic flow diagram of a base station power saving method according to another embodiment of the present invention, where the base station power saving method in this example is applied to an RRU end, and as shown in fig. 2, the base station power saving method includes the following steps:
step 201: when the RRU is controlled to be in an on state by the BBU connected with the RRU, the motion information of the target object is detected.
Specifically, when the RRU is controlled to be in an on state by a BBU connected with the RRU, detecting whether a target object moves into a cell of the BBU in the on state;
when the first RRU detects that the target object moves to the cell of the BBU in the open state, determining the moving direction of the target object as a first direction; when the tail RRU detects that the target object moves to the cell of the BBU in the open state, determining the moving direction of the target object as a second direction;
