Detailed Description
The technical solution of the present disclosure is further described in detail by the accompanying drawings and examples.
The inventor finds that under some micro base station application scenes, such as office buildings, shopping malls, student apartments and other scenes with regular user activities, no matter how many users, the 5G micro base station is always in a working state, and no specific energy-saving scheme exists. Under the condition of continuous working of the base station, not only electric energy is consumed, but also the service life of base station equipment is greatly reduced. The base station is intelligently adjusted to be switched to a working state or a dormant state according to the parameters such as the number of users in the coverage area of the base station and the user traffic, so that the aim of saving energy is fulfilled.
A flow chart of some embodiments of a base station control method of the present disclosure is shown in fig. 1.
In step 101, determining topology information of the micro base station according to the internal structure of the building, wherein the topology information of the micro base station comprises a topology sequence of the micro base station according to the internal channel of the building. The micro base station is base station equipment which is much smaller than a traditional macro base station in terms of product form, emission power, coverage range and the like, the power of the micro base station is generally only 500 mW-12.6W, and the coverage range is 50 m-200 m.
In some embodiments, the micro base station deployment information meeting the indoor coverage planning requirement can be acquired, the topology of the micro base stations is subjected to sequencing calculation based on the idea of graph theory, the topology information of the micro base stations is determined, and in the obtained topology information, the next micro base station adjacent to the topology sequence is the next-stage micro base station of the current micro base station.
In step 102, base station state handover thresholds for various micro base stations inside the building are determined. In some embodiments, the base station state switching threshold includes one or more of a base station user connection number threshold, an uplink and downlink traffic threshold, or an uplink and downlink physical resource block utilization threshold.
In step 103, according to the parameters of the current micro base station and the base station state switching threshold, it is determined whether to switch the current micro base station and the working state of the next-stage micro base station of the current micro base station according to the topological sequence.
In some embodiments, in a case that the parameter of the current micro base station is greater than or equal to the base station state switching threshold of the current micro base station, a micro base station in a dormant state in a next-stage micro base station according to the topological sequence of the current micro base station may be switched to an active state. In some embodiments, the current micro base station may be switched to the sleep state in case the parameter of the current micro base station is smaller than the base station state switching threshold of the current micro base station.
By the method, the characteristics that the channel inside the building is limited and the channel has the passing direction can be considered, the base station to be switched to the working state is determined by utilizing the position relation between the base stations, so that the base station can be switched between the dormant state and the active state, the micro base station service can be provided for users under the condition that the active state is not kept for a long time, and the energy consumption of the micro base station is reduced under the condition that the service quality of the users is not reduced.
In some embodiments, there are many KPI (Key Performance Indicator) indicators for measuring the operating state of a base station, and when the traffic is dense, the connection number, the uplink and downlink traffic, and the utilization rate of PRB (Physical Resource Block) of the base station user will change significantly, so the base station control apparatus can set different parameter thresholds for the three indicators according to the model of the micro base station device and the U (uplink)/D (downlink) timeslot setting for each micro base station. For example, a single micro base station with an upper limit of N for the number of base station user connections0The base station ensures that the peak values of the uplink and downlink flow rates normally used by the user are I respectivelyDLAnd IULThe highest utilization rate of the uplink PRB and the downlink PRB is respectively C1And C2。
For example, the base station user connection number threshold may be set to 0.6N0The threshold value of the uplink and downlink flow is 0.8IDLAnd 0.8IULThe threshold value of the utilization rate of the uplink PRB and the downlink PRB is 0.8C1And 0.8C2. When the current base station meets one or more of the following conditions, the next stage of base station can be awakened through the central control station of the base station:
1. the number of the base station user connections reaches the set threshold value
2. The uplink and downlink flow reaches the set threshold value
3. The utilization rate of the uplink PRB and the downlink PRB reaches a set threshold value
By the method, the working state of the base station can be comprehensively evaluated, so that the threshold value accords with the bearing capacity of the base station, and the accuracy of switching the working state of the base station is improved.
In some embodiments, the micro base station in the dormant state switches to the active state after going dormant for a predetermined dormant time period. In some embodiments, after the micro base station in the active state operates for a predetermined wake-up time, whether the activation condition is still satisfied is determined again, and if the activation condition is no longer satisfied, the micro base station may be switched to the sleep state.
By the method, the micro base station can be prevented from being in a dormant state or an activated state for a long time based on the expired parameter information in a time threshold setting mode, and the circulation of state switching is facilitated; the base station can be kept in a starting state most of the time during the people flow of the building while the energy conservation and emission reduction of the base station are ensured, and the service can be better provided for users.
In some embodiments, each time the state of the base station is switched, the base station control device stores the state information of the corresponding base station, so that the base station control device can timely master and update the state of each base station, and the robustness of the system is improved.
Flow diagrams of further embodiments of the base station control methods of the present disclosure are shown in fig. 2.
In step 201, micro base station topology information is determined from the building internal structure. In some embodiments, according to indoor coverage planning requirements, a 5G micro base station may be arranged in a specific building environment under the condition of ensuring user service quality, wherein the arrangement purpose includes performing local blind compensation on a weak coverage area or a no coverage area of a macro base station; constructing a micro base station indoor network coverage system, increasing the capacity of a hot spot area and absorbing telephone traffic hot spots; the problem of deep coverage of high-rise buildings is solved; and performing signal enhancement, coverage planning and the like on the area with difficult indoor branch construction by using a small RRU (Remote Radio Unit) + BBU (Building Base band Unit) system.
In step 202, base station state handover thresholds for various micro base stations inside the building are determined. In some embodiments, the base station state handover parameters of different micro base stations may be the same or different. The method can be determined according to the bearing condition of the micro base station, or the user corresponding to the position of the micro base station and the service pressure degree of the user.
In step 203, it is determined whether the parameter of the current micro base station is greater than or equal to the base station state switching threshold of the current micro base station. If the parameter of the current micro base station is greater than or equal to the base station state switching threshold value of the current micro base station, executing step 204; otherwise, step 205 is performed.
In some embodiments, the parameter of the current micro base station may be a parameter acquired for a duration of time, which may be a predetermined wake-up time T1。
In some embodiments, in order to smoothly start control over each micro base station in a building, the micro base station at the door of the building can be kept in a working state, so that the entering and exiting of monitored personnel can be ensured, the accuracy of subsequent judgment is improved, and the error rate is reduced.
In step 204, the micro base station in the dormant state in the next-stage micro base station according to the topological sequence of the current micro base station is switched to the active state. In some embodiments, the base station control apparatus may send a state switching instruction to the base station to switch the operating state of the corresponding base station.
In step 205, the current micro base station is switched to the sleep state. In some embodiments, the base station control apparatus may send a state switching instruction to the base station to switch the operating state of the corresponding base station.
In step 206, it is determined whether the current micro base station dormancy reaches the predetermined dormancy duration T2. In case that the predetermined sleep time period is reached, executing step 207; otherwise, if not being awakened, the sleep state is continuously kept.
In step 207, the handover is active and measurement of the parameters of the current base station is started for subsequent comparison with the base station state handover threshold.
In step 208, it is determined whether a predetermined wake-up period has been reached since activation. If the predetermined wake-up time is reached, step 203 is executed.
By the method, the problems of insufficient channels in a hot spot area and poor signals in a building can be solved aiming at the rapidly developed 5G micro base station arrangement. Meanwhile, the base stations are subjected to sequencing calculation of topological positions based on the idea of graph theory, the start and dormancy of the micro base stations are controlled by setting thresholds and awakening/dormancy time for the connection number, uplink and downlink flow and PRB utilization rate of base station users in a network architecture, so that the purposes of high efficiency and energy saving are achieved, the purposes of micro base station planning and base station energy conservation and emission reduction are achieved, the network performance is ensured, the potential of network energy conservation is fully exerted, and a new idea and experimental direction are provided in the aspect of base station energy conservation and emission reduction. In addition, the base station is given proper sleep time, so that the consumption of electric energy can be reduced, the load capacity of the base station is fully utilized, the service life of base station equipment is effectively prolonged, and the operation and maintenance cost of an operator is greatly reduced while the normal service quality of a user is provided.
In some embodiments, the micro base station deployment may be performed inside the building, and then the topology information may be obtained based on the deployed micro base station condition. A flow chart of some embodiments of micro base station deployment in the base station control method of the present disclosure is shown in fig. 3.
In step 301, the building interior configuration and the general hot spot area of the building are known.
In step 302, the arrangement requirement of the 5G micro base station is obtained by means of user feedback and signal checking.
In step 303, preliminary layout positions of the 5G micro base stations are determined based on the layout requirements.
In step 304, the layout positions to be determined are determined in the preliminary layout positions according to the statistical situation of the signal usage in the areas to be laid out. And screening out hotspot areas in the building according to the statistical conditions (including numerical values such as user connection quantity, up-down flow quantity and the like which are sorted according to the size) of the signal use of the areas to be laid out, and taking the hotspot areas as candidate positions to be laid out.
In step 305, horizontal layout simulation and height layout simulation are performed in the layout positions to be determined to determine accurate layout positions in the layout positions to be determined.
In step 306, the 5G micro base stations are arranged according to the precise layout positions, so as to complete the overall planning of the coverage requirement of the building.
By the method, the micro base stations can be arranged according to the practical application scene of the indoor building, so that the problems of insufficient channels in a hot spot area and poor signals in the building are solved, the individual requirements of the internal environment and the use characteristics of the building are met, and the service quality is improved.
In some embodiments, after the micro base station deployment is completed, the topology information determination is further performed based on the building internal construction and the micro base station deployment situation. In some embodiments, according to the position and the traffic direction of the building internal passage and the coverage area of each micro base station, determining the sequence of the micro base stations corresponding to the coverage area passed by the person passing through the building internal passage, and determining the topological sequence of the micro base stations according to the sequence.
Taking the micro base station arrangement of the three-storey mall building as an example shown in fig. 4A, after entering the mall from the right population, it can be seen that the micro base stations arranged in order are already arranged on different floors respectively. And the head and the tail of the floor are respectively provided with stairs for ascending and descending. According to the idea of graph theory topology ordering, in a directed acyclic graph, each point has an in-edge or an out-edge, when the point is marked, all its predecessors are marked, and finally a linear table arranged according to the sequence is a topology sequence.
Taking the mall as an example (only taking the direction of people flow forward), it can be known that the people entering the mall have two options after passing through the base station 1, that is, the people continue to advance on the first floor through the base station 2 and continue to advance on the second floor through the base station 4. If the user selects to go forward to the first floor through the base station 2, the user can only go forward to the base station 3; if the second floor is selected to continue to advance through the base station 4, two selection branches are provided, namely, the second floor continues to advance through the base station 5 and the third floor continues to advance through the base station 7; by analogy, a directed graph of the advancing direction of the mall base station can be obtained, as shown in fig. 4B.
Therefore, taking base station 1 as an example, the next-level neighboring base stations are base station 2 and base station 4; the next level base station of the base station 2 is only the base station 3, and the next level adjacent base stations of the base station 4 are the base station 5 and the base station 7, and so on, the relevant information of the current base station and the next level relevant base station can be obtained.
By the method, the base station topology information which accords with the internal structure and use characteristics of the building can be obtained, the individuation degree of mastering the internal condition of the building is improved, the accuracy of base station control is improved, and the energy-saving effect is further optimized.
A schematic diagram of some embodiments of a base station control apparatus of the present disclosure is shown in fig. 5.
The topology information determining unit 501 can determine micro base station topology information according to the building internal structure, where the micro base station topology information includes a topology sequence of micro base stations according to the building internal channel. In some embodiments, the micro base station deployment inside the building can be performed based on the embodiment shown in fig. 3, and the topology of the micro base station is subjected to ranking calculation based on the graph theory idea, so as to determine the topology information of the micro base station. In the obtained topology information, the next micro base station adjacent to the topology sequence is the next micro base station of the current micro base station.
The threshold determination unit 502 can determine a base station state switching threshold for each micro base station inside the building. In some embodiments, the base station state switching threshold includes one or more of a base station user connection number threshold, an uplink and downlink traffic threshold, or an uplink and downlink physical resource block utilization threshold.
The state switching unit 503 can determine whether to switch the current micro base station and the working state of the next-stage micro base station of the current micro base station according to the topological sequence according to the parameter of the current micro base station and the base station state switching threshold. In some embodiments, in a case that the parameter of the current micro base station is greater than or equal to the base station state switching threshold of the current micro base station, a micro base station in a dormant state in a next-stage micro base station according to the topological sequence of the current micro base station may be switched to an active state. In some embodiments, the current micro base station may be switched to the sleep state in case the parameter of the current micro base station is smaller than the base station state switching threshold of the current micro base station.
The base station control device can determine the base station to be switched to the working state by utilizing the position relation between the base stations based on the characteristics that the channel in the building is limited and the traffic direction exists, so that the base station can be switched between the dormant state and the active state, the micro base station service can be provided for users under the condition that the active state is not kept for a long time, and the energy consumption of the micro base station is reduced under the condition that the service quality of the users is not reduced.

The base station control apparatus comprises a memory 601 and a processor 602. Wherein: the memory 601 may be a magnetic disk, flash memory, or any other non-volatile storage medium.
