Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to an energy-saving method and device for covering a superposed cell.
Background
Energy conservation, emission reduction, environmental protection and the like are the hot points concerned by the current society, and the high energy consumption of the telecommunication industry also draws high attention of the society. With the construction of mobile communication networks, the demand of operators for energy consumption is increasing. Therefore, the effective cell energy-saving method not only reduces the operation cost of enterprises, but also embodies social responsibility. At present, operators cover a part of areas in the form of heterogeneous networks such as 'macro cell + micro cell' or 'macro cell + indoor sub cell', macro base stations in the macro cell guarantee basic coverage to meet basic voice data service requirements, and micro base stations or indoor sub base stations corresponding to the micro cell or the indoor sub cell are placed in the macro cell to guarantee hot spot area coverage to meet large data volume service requirements.
Because the communication traffic of the base station in different periods of the whole day is unevenly distributed, a period with low traffic is called idle time, and a period with high traffic is called busy time. For example, in office buildings or schools and other places, the traffic of such areas is usually large in the daytime, and after 5 or 6 pm, the traffic of the areas of the office buildings or teaching buildings is sharply reduced along with work or school leaving, so that an obvious tidal effect is presented. When such stations enter idle communication, the communication load is low, and if the micro base station or the indoor sub base station still maintains an open state, unnecessary energy consumption is brought. Therefore, for the heterogeneous network, all users of the micro cell or the indoor sub-cell are moved to the macro cell in idle time, and the micro cell or the indoor sub-cell is closed, so that the energy consumption of the system can be effectively reduced.
However, since the signal strength of the coverage areas of the macro cell and the micro cell or the coverage areas of the macro cell and the indoor sub-cell are different, if the micro cell or the indoor sub-cell is directly closed, a coverage hole will be generated, which easily causes problems such as handover failure, call drop, and non-connection.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of an energy saving method for covering a superposed cell according to an embodiment of the present invention, as shown in fig. 1, the method includes:
step S11, periodically acquiring measurement report data of all energy-saving targets to be saved in a heterogeneous network area within a preset time period and macro cells overlapping with the energy-saving targets to be saved in a covering mode;
specifically, at present, operators deploy multi-level heterogeneous networks to meet user requirements in dense areas, and in the case that a macro cell of such areas (such as a commercial street, an office building, a college, and the like) guarantees basic signal coverage, traffic is shared in modes of a micro cell, a room-to-cell, and the like, so that network quality and user perception are improved. In a heterogeneous network area such as a macro cell + a micro cell or a macro cell + a cell, Measurement Report data (MR data) is sent to a network server at intervals between a target to be energy-saved and the macro cell, so that MR data of the target to be energy-saved and the macro cell within a period of time can be periodically acquired from the network server. For example, the target to be energy-saved and the macro cell send MR data to the network server once every 480ms, the MR data acquisition period is set to once every week, and the acquisition time granularity is set to be monday and whole day, so that all MR data of 0:00-24:00 of the target to be energy-saved and MR data of 0:00-24:00 of the macro cell whole day, which are overlapped with the coverage of the energy-saving target, can be acquired from the network server every monday in the state that all targets to be energy-saved are started and normally operate.
Step S12, determining a first average reference signal received power of the target to be energy-saved according to the measurement report data of the target to be energy-saved, and determining a second average reference signal received power of the macro cell according to the measurement report data of the macro cell;
specifically, the MR data of the target to be energy-saved is analyzed, Reference Signal Receiving Power (RSRP) of the target to be energy-saved is obtained, in practical application, an RSRP value of the target to be energy-saved can be obtained by analyzing an mr.rsrp field, wherein each access user of the target to be energy-saved generates an RSRP value, and an average RSRP value of the target to be energy-saved is calculated according to the obtained RSRP value. And analyzing the MR data of the macro cell, acquiring an RSRP value which is overlapped with the target to be saved in the macro cell, and calculating an average RSRP value of the macro cell relative to the target to be saved in energy according to the acquired RSRP value. For convenience of distinguishing, the average RSRP value of the target to be energy-saved is recorded as a first average RSRP, and the average RSRP value of the macro cell is recorded as a second average RSRP.
For example, the access users to be energy-saving targets are A, B and C, the corresponding RSRP values are RSRP-A, RSRP-B and RSRP-C, respectively, the first average RSRP value of the energy-saving targets is (RSRP- ｃA + RSRP-B + RSRP-C)/3, the mr.rsrp field of the macro cell is analyzed, and it is determined that the access users in the macro cell have RSRP values corresponding to A, B and C: and the RSRP-A ', the RSRP-B' and the RSRP-C ', the second average RSRP value of the macro cell relative to the targets to be energy-saving is (RSRP-A' + RSRP-B '+ RSRP-C')/3, so that the first average RSRP of each target to be energy-saving and the second average RSRP of the macro cell which is overlapped with the coverage of the energy-saving target can be determined. For example, the average RSRP of target to be energy-saved a is-98.25 dB, the average RSRP of macro cell B coinciding with its coverage is-113.89 dB, the average RSRP of macro cell C coinciding with its coverage is-115.41 dB, etc.
Step S13, determining the strongest adjacent region of the target to be energy-saved and the third average reference signal received power of the strongest adjacent region according to the second average reference signal received power;
specifically, the second average RSRP of the macro cell overlapping with the target coverage to be energy-saved is ranked one by one according to the size, the strongest neighboring cell in the macro cell is determined, and the second average RSRP corresponding to the strongest neighboring cell is marked as the third average RSRP. According to the reselection/handover principle of the terminal based on the signal strength, after a micro cell or a room sub cell is closed, a user can preferentially occupy the strongest adjacent cell for service, so that in the embodiment of the invention, the strongest adjacent cell corresponding to each target to be energy-saving needs to be determined. For example, the average RSRP of the macro cell B and the macro cell C overlapping with the target to be energy-saved a in coverage is-113.89 dB and-115.41 dB, respectively, the strongest adjacent cell of the target to be energy-saved a is the macro cell B, and the corresponding third average RSRP is-113.89 dB.
Step S14, if it is judged and obtained that the first average reference signal received power and the third average reference signal received power meet a preset intensity condition, associating a target to be energy-saved corresponding to the first average reference signal received power and a macro cell corresponding to the third average reference signal received power, and determining a target table to be energy-saved;
specifically, in order to reduce the coverage hole, a preset condition may be set, and the target to be energy-saved may be closed only when the first average reference signal received power and the third average reference signal received power satisfy the preset strength condition, so as to avoid a coverage hole generated during user handover and ensure communication service quality. Firstly, judging whether a first average RSRP and a corresponding third average RSRP meet a preset intensity condition, if so, associating a target to be energy-saved corresponding to the first average RSRP and a macro cell corresponding to the third average RSRP, and determining a target table to be energy-saved.
For example, the average RSRP of the target to be energy-saved a is-98.25 dB, the strongest neighbor macro cell B thereof is, and the corresponding third average RSRP is-113.89 dB. And judging whether-98.25 dB and-113.89 dB meet a preset intensity condition, if so, associating the target A to be energy-saved with the macro cell B, and generating a target table to be energy-saved. When the target to be energy-saved in the target table to be energy-saved is closed, the user will switch to the macro cell associated with the target to be energy-saved, and no coverage hole will be generated.
Step S15, if it is judged and known that the communication traffic of the target to be energy-saved in the target table to be energy-saved is smaller than a preset traffic threshold, and the target to be energy-saved and the corresponding macro cell meet a preset energy-saving triggering condition, migrating the user in the target to be energy-saved to the macro cell, and closing the target to be energy-saved.
Specifically, the communication traffic in the heterogeneous network changes in a tide manner with time, for example, after 5 or 6 pm, the traffic of an office building or a teaching building such as a building area is rapidly reduced with work or school leaving, so that the communication traffic information of 0:00 to 24:00 of the target to be energy-saved in the whole day can be acquired, for example, the target to be energy-saved automatically uploads load information to a network server at intervals, the communication traffic of the target to be energy-saved is determined according to the load information, and when the communication traffic is lower than a preset traffic threshold, the target to be energy-saved is in a communication idle state, and the target to be energy-saved can be closed. In practical application, when communication of the target to be energy-saved is idle, the energy-saving time period of the target to be energy-saved is determined, for example, the energy-saving time period is 21:00-6:00, in the energy-saving time period, whether the energy-saving target in the target table to be energy-saved and the corresponding macro cell meet a preset energy-saving trigger condition is determined, if yes, a reselection/switching instruction is issued to the target to be energy-saved, a user is moved to the corresponding macro cell, the target to be energy-saved is closed, and an energy-saving mode is entered.
According to the energy-saving method for covering the overlapped cell, provided by the embodiment of the invention, the signal intensity of the target to be energy-saved and the macro cell in the adjacent cell thereof is determined through the measurement report data, the target to be energy-saved is screened according to the signal intensity and is counted into the target table to be energy-saved, the target to be energy-saved with extremely little service volume or user volume is closed in the communication idle time period by comprehensively considering the number of users and the change condition of the service volume all day, so that the power consumption of the base station is reduced.
On the basis of the foregoing embodiment, further, if it is determined that the first average reference signal received power and the third average reference signal received power satisfy the preset strength condition, associating the target to be energy-saved corresponding to the first average reference signal received power and the macro cell corresponding to the third average reference signal received power includes:
and if the difference value between the first average reference signal received power and the third average reference signal received power is judged and obtained to be smaller than or equal to a first threshold, associating the target to be energy-saved corresponding to the first average reference signal received power and the macro cell corresponding to the third average reference signal received power.
Specifically, a difference value between a first average RSRP of the target to be energy-saved and a third average RSRP of the corresponding macro cell is calculated, if the difference value is smaller than or equal to a first threshold value, it is indicated that the difference between the signal strengths of the target to be energy-saved and the third average RSRP of the macro cell is small, and after a user in the target to be energy-saved is switched to the macro cell, a coverage hole is not generated, and at this time, the target to be energy-saved and the macro cell can be associated to determine a target table to be energy-saved. The first threshold may be set according to practical situations, for example, the first threshold is set to 3 dB.
For example, if the average RSRP of the target to be energy-saved a is-100.48 dBm, the macro cell B in the strongest neighboring cell thereof, the corresponding third average RSRP is-102.89 dBm, the difference is 2.41dB, and is less than the first threshold by 3dB, the target to be energy-saved a and the macro cell B are associated, and a target table to be energy-saved is generated. The target table to be energy-saving includes an energy-saving target A and a macro cell B, when the target A to be energy-saving is closed, the user will switch to the macro cell B, and no coverage hole will be generated.
According to the energy-saving method for covering the overlapped cell, provided by the embodiment of the invention, the signal intensity of the target to be energy-saved and the macro cell in the adjacent cell thereof is determined through the measurement report data, the target to be energy-saved is screened according to the preset threshold and the signal intensity, the problem of coverage holes is avoided, the target to be energy-saved with extremely small service volume or user volume is closed in the communication idle time period by comprehensively considering the number of users and the change condition of the service volume all day, so that the power consumption of a base station is reduced, the energy-saving efficiency is further improved, the power consumption of the base station is effectively reduced, and the communication service quality is ensured.
On the basis of the foregoing embodiments, further, if it is determined that the first average reference signal received power and the third average reference signal received power satisfy the preset strength condition, associating the target to be energy-saved corresponding to the first average reference signal received power and the macro cell corresponding to the third average reference signal received power includes:
and if the difference value between the first average reference signal received power and the third average reference signal received power is judged to be larger than a first threshold value, and the third average reference signal received power is larger than a second threshold value, associating the target to be energy-saved corresponding to the first average reference signal received power and the macro cell corresponding to the third average reference signal received power.
Specifically, in the communication system, the weak coverage is defined as weak coverage when the average RSRP is less than the second threshold. The second threshold may be set manually according to actual conditions, and is generally a coverage level value that does not affect service requirements and user perception, for example, the second threshold is set to-110 dBm. Calculating a difference value between a first average RSRP of a target to be energy-saved and a third average RSRP of a corresponding macro cell, if the difference value is larger than a first threshold value, indicating that the difference value between the signal strengths of the target to be energy-saved and the macro cell is larger, at the moment, judging the signal strength of the macro cell, if the third average RSRP is larger than a second threshold value, indicating that the signal strength of the macro cell is large, switching a user in the target to be energy-saved to the macro cell, not generating a coverage hole, at the moment, associating the target to be energy-saved and the macro cell, and determining a target table to be energy-saved.
For example, the average RSRP of the target a to be energy-saved is-100.48 dBm, the macro cell B in the strongest neighboring cell thereof has a corresponding third average RSRP of-108.89 dBm, the difference value is 8.41dB and is greater than the first threshold value by 3dB, but the third average RSRP is greater than-110 dBm, and the target a to be energy-saved and the macro cell B are associated to generate a target table to be energy-saved. The target table to be energy-saved comprises an energy-saving target A and a macro cell B, when the target A to be energy-saved is closed, a user can switch to the macro cell B, and because the macro cell B is high in signal intensity, no coverage hole is generated.
According to the energy-saving method for covering the overlapped cell, provided by the embodiment of the invention, the signal intensity of the target to be energy-saved and the macro cell in the adjacent cell thereof is determined through the measurement report data, the target to be energy-saved is screened according to the preset threshold and the signal intensity, the problem of coverage holes is avoided, the target to be energy-saved with extremely small service volume or user volume is closed in the communication idle time period by comprehensively considering the number of users and the change condition of the service volume all day, so that the power consumption of a base station is reduced, the energy-saving efficiency is further improved, the power consumption of the base station is effectively reduced, and the communication service quality is ensured.
On the basis of the foregoing embodiments, further, the target to be energy-saved is a first cell or a radio frequency unit of the first cell, where the first cell is a micro cell and/or a cell.
Specifically, the target to be energy-saved may be set as a cell to be energy-saved based on a cell level, for example, if the cell to be energy-saved is a micro cell or a cell in a room, measurement report data of all cells in a heterogeneous network region within a preset time period is periodically obtained, where the cells include a macro cell, a micro cell, and a cell in a room. In practical application, a cell-level-based MR measurement mode is started on a network side, MR data of each cell can be acquired, then a first average RSRP of the cell to be energy-saved is determined according to the MR data of the cell to be energy-saved, a second average RSRP is determined according to the MR data of a macro cell, the second average RSRP of the macro cell overlapped with the coverage of the cell to be energy-saved is sequenced, the strongest adjacent cell of the cell to be energy-saved is determined, when the average RSRP of the cell to be energy-saved and the strongest adjacent cell is judged to meet a preset strength condition, the macro cell corresponding to the cell to be energy-saved and the strongest adjacent cell is associated, and a cell table to be energy-saved is determined.
When the communication is idle, if judging that the cell to be energy-saved in the cell list to be energy-saved and the macro cell corresponding to the cell to be energy-saved meet the preset energy-saving triggering condition, moving the user in the cell to be energy-saved to the macro cell corresponding to the cell to be energy-saved in the cell list to be energy-saved, and closing the cell to be energy-saved. For example, if the CELL to be energy-saved CELL1 and the corresponding macrocell CELLA satisfy the preset energy-saving trigger condition, the ECLL1 is turned off.
In practical application, each of the micro cell and the macro cell is provided with a Radio Remote Unit (RRU), and a plurality of RRUs are usually provided in the indoor sub-cell, and if the average RSRP of the indoor sub-cell does not meet the preset strength condition, the indoor sub-cell cannot be brought into the target to be saved in energy.
Specifically, measurement report data of all radio frequency units in a heterogeneous network region within a preset time period is periodically acquired, where the radio frequency units include radio frequency units of a macro cell, a micro cell, and a cell. In practical application, an RRU-level-based MR measurement mode is started on a network side, MR data of each radio frequency unit can be acquired, then a first average RSRP of the radio frequency unit to be energy-saved is determined according to the MR data of the radio frequency unit to be energy-saved, a second average RSRP is determined according to the MR data of the radio frequency unit of a macro cell, the second average RSRP of the macro cell overlapped with the coverage of the radio frequency unit to be energy-saved is sequenced, the strongest adjacent region of the radio frequency unit to be energy-saved is determined, when the average RSRP of the radio frequency unit to be energy-saved and the strongest adjacent region meets a preset strength condition, the radio frequency unit corresponding to the radio frequency unit to be energy-saved and the strongest adjacent region are correlated, and a radio frequency unit table to be energy-saved is determined.
When the communication is idle, if judging that the radio frequency unit to be energy-saved in the radio frequency unit table to be energy-saved and the macro cell corresponding to the radio frequency unit to be energy-saved meet the preset energy-saving triggering condition, moving the user in the radio frequency unit to be energy-saved to the macro cell corresponding to the radio frequency unit to be energy-saved in the radio frequency unit table to be energy-saved, and closing the radio frequency unit to be energy-saved. For example, if the RRU1 in the CELL1 and the macrocell CELLA corresponding thereto satisfy the preset energy saving trigger condition, the RRU1 in the ECLL1 is turned off. For example, fig. 2 is a schematic coverage diagram of "macro CELL + CELL division" provided by an embodiment of the present invention, as shown in fig. 2, a 5-layer teaching building in a college, 1 radio unit RRU is distributed in each of 1, 2, 3, 4, and 5 layers, and is divided into 2 CELLs for coverage, where a CELL1 covers 1 layer and 2 layers, a CELL2 covers 3 layers, 4 layers, and 5 layers, macro CELLs CELLA and CELLB exist outdoors, the radio units included are RRUA and RRUB, and information conditions of each CELL are shown in table 1:

Specifically, the acquiring module 71 periodically acquires MR data of the target to be energy-saved and the macro cell for a period of time.

For convenience of distinguishing, the average RSRP value of the target to be energy-saved is recorded as a first average RSRP, and the average RSRP value of the macro cell is recorded as a second average RSRP. The calculating module 73 sequentially sorts the second average RSRP of the macro cell overlapping with the target coverage to be energy-saved according to the size, determines the strongest neighboring cell in the macro cell, and marks the second average RSRP corresponding to the strongest neighboring cell as the third average RSRP.
