Description

Technical Field

[0001] The present invention relates to the field of mobile communication technologies, and in particular to a small base station control method, device, network management equipment, and a small base station. Background Art

[0002] Currently, network coverage is gradually improving, but there are still areas with overlapping signal coverage. When operators receive customer complaints about signal coverage issues, they can install wireless equipment such as small base stations on-site to fill in signal blind spots.

[0003] Among them, the integrated small base station can work without clock synchronization. However, although the small base station solves the signal coverage problem complained by individual customers, it will seriously interfere with the surrounding base stations with the same frequency, thereby reducing the overall network performance and even causing more complaints; and after the small base station is installed, if a new macro base station is built nearby and it can completely cover the previous complaint blind spot, it will cause a waste of the small base station, and the small base station will become an interference source. Therefore, when the aforementioned problems occur, it is necessary to locate the small base station with the above problems, so that the installation and maintenance personnel can go to the site to uninstall the small base station, which wastes manpower. In addition, if a small base station is dismantled, the nearby macro base station is dismantled or damaged, and the original complaint location becomes a coverage blind spot again, then the small base station needs to be reinstalled (such as Figure 1 shown).

[0004] As can be seen from the above, when network coverage changes, small base stations need to be manually dismantled or installed repeatedly, which is cumbersome and wastes manpower. Summary of the Invention

[0005] The embodiments of the present invention provide a small base station control method, device, network management equipment and small base station to solve the problem in the prior art that when network coverage changes, small base stations need to be manually dismantled or installed repeatedly, which is cumbersome and wastes manpower.

[0013] The control module is used to control the turning on and off of the base station function of the second small base station according to the measurement report, or to adjust the transmission power of the base station function of the second small base station when it is turned on.

[0014] In a fourth aspect, an embodiment of the present invention provides a small base station control device, which is applied to a small base station, and the device includes:

[0015] The first reporting module is configured to access the macro base station through a dialing function when the base station function of the small base station is disabled, and report a measurement report to the macro base station.

[0016] In a fifth aspect, an embodiment of the present invention provides a network management device, including a memory, a transceiver, and a processor:

[0017] A memory for storing computer programs; a transceiver for sending and receiving data under the control of the processor; and a processor for reading the computer program in the memory and executing the small base station control method described in the first aspect above.

[0018] In a sixth aspect, an embodiment of the present invention provides a small base station, including a memory, a transceiver, and a processor:

[0019] A memory for storing computer programs; a transceiver for sending and receiving data under the control of the processor; and a processor for reading the computer program in the memory and executing the small base station control method described in the second aspect above.

[0021] In an embodiment of the present invention, the network management device can obtain measurement reports of multiple terminal devices, as well as measurement reports when the first small base station is accessed as a terminal device to the macro base station, thereby controlling the opening and closing of the base station function of the second small base station according to the measurement report, or adjusting the transmission power of the base station function of the second small base station when it is turned on. It can be seen that in an embodiment of the present invention, the first small base station can be accessed as a terminal device to the macro base station, thereby sending a measurement report to the network management device, so that the network management device controls the base station function of the second small base station according to the measurement report of the first small base station and the measurement reports of multiple terminal devices.

[0031] In embodiments of the present invention, the term "and / or" describes the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0032] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] The embodiments of the present application provide a small base station control method, device, network management equipment and small base station, which are used to solve the problem in the prior art that when network coverage changes, small base stations need to be manually dismantled or installed repeatedly, which is cumbersome and wastes manpower.

[0035] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0036] Figure 2 The flowchart of a small base station control method provided by an embodiment of the present invention is shown. The method can be applied to network management equipment, such as Figure 2 As shown, the method may include the following steps:

[0037] Step 201: Obtain measurement reports of multiple terminal devices, as well as a measurement report when the first small base station accesses the macro base station as a terminal device.

[0038] The measurement report includes the signal quality of the primary serving cell and the signal quality of multiple neighboring cells of the primary serving cell. The signal quality can be expressed as Reference Signal Receiving Power (RSRP) / Signal to Interference plus Noise Ratio (SINR).

[0039] In addition, in an embodiment of the present invention, when the base station function is disabled, the first small base station can access the macro base station (i.e., the macro base stations surrounding the first small base station) as a terminal device and report a measurement report to the network side. For example, if a dialing test module is provided in the first small base station, the first small base station can access the macro base station through the dialing test module.

[0040] In addition, the measurement report of the terminal device may be a measurement report when the terminal device first enters a cell of a predetermined base station (including a macro base station and / or a small base station); the predetermined base station, and the macro base station to which the first small base station accesses, may be a base station within a predetermined area. For example, if there are multiple macro base stations and multiple small base stations within the predetermined area, the terminal device submits a measurement report when it first enters the cells of these macro base stations and the cells of small base stations with the base station function enabled.

[0041] Step 202: According to the measurement report, control the turning on and off of the base station function of the second small base station, or adjust the transmission power of the second small base station when the base station function is turned on.

[0042] Among them, the above-mentioned second small base station may include one or more small base stations, and the above-mentioned first small base station may also include one or more small base stations; the base stations included in the above-mentioned first small base station and the second small base station may be the same small base station or different small base stations.

[0043] Therefore, in an embodiment of the present invention, the base station function of the small base station can be controlled to be turned on and off, or the transmit power of the small base station when the base station function is turned on can be adjusted according to the measurement reports of multiple terminal devices and the measurement report when the small base station accesses the macro base station as a terminal device;

[0044] Alternatively, based on the measurement reports of multiple terminal devices and the measurement reports of the small base station when it accesses the macro base station as a terminal device, the base station functions of other small base stations can be controlled to be turned on and off, or the transmission power of the base station functions of other small base stations when they are turned on can be adjusted.

[0045] It can be seen from the aforementioned steps 201 to 202 that in an embodiment of the present invention, the network management device can obtain measurement reports of multiple terminal devices, as well as measurement reports when the first small base station accesses the macro base station as a terminal device, thereby controlling the turning on and off of the base station function of the second small base station according to the measurement report, or adjusting the transmission power of the second small base station when the base station function is turned on.

[0046] It can be seen from this that in an embodiment of the present invention, the first small base station can access the macro base station as a terminal device, thereby sending a measurement report to the network management device, so that the network management device controls the base station function of the second small base station based on the measurement report of the first small base station and the measurement reports of multiple terminal devices. Among them, the measurement report can indicate the network coverage situation. Therefore, in an embodiment of the present invention, the small base station can be automatically turned on or off according to the actual network coverage situation, or the transmission power of the small base station when the base station function is turned on can be adjusted. In this way, when the network coverage changes, there is no need to manually remove or install the small base station repeatedly, thereby simplifying the control process of the small base station and saving manpower.

[0047] That is, in an embodiment of the present invention, the power of the small base station can be automatically adjusted according to the actual network coverage situation, or the base station function of the small base station can be turned on or off, so as to better utilize the integrated small base station, that is, to achieve the effect of timely discovery of blind spots, reduction of complaints, and rapid blind spot filling, while trying to avoid interference with the surrounding area and optimize network performance. At the same time, there is no need for installation and maintenance personnel to visit frequently, which improves efficiency while saving manpower and even energy consumption.

[0048] Optionally, controlling the turning on and off of the base station function of the second small base station according to the measurement report, or adjusting the transmit power when the base station function of the second small base station is turned on, includes:

[0049] When the target duration is greater than the first preset threshold, controlling the turning on and off of the base station function of the second small base station according to the measurement report, or adjusting the transmit power of the second small base station when the base station function is turned on;

[0050] The target duration is the duration between the last time the base station function of the second small base station was controlled and the current time.

[0051] Among them, controlling the base station function of the second small base station includes: controlling the turning on and off of the base station function of the second small base station, or adjusting the transmission power when the base station function of the second small base station is turned on.

[0052] It can be seen from this that in an embodiment of the present invention, within a time period of a target duration, the base station control function of the second small base station is only controlled once, that is, the time interval limit for controlling the base station function of the small base station is increased, and power adjustment, opening or closing is only triggered once within the statistical time, thereby preventing frequent control of the small base station from causing network instability.

[0053] Optionally, before controlling the turning on and off of the base station function of the second small base station according to the measurement report, or adjusting the transmit power when the base station function of the second small base station is turned on, the method further includes:

[0054] Obtaining the geographical location of the terminal device when reporting the measurement report, and the geographical location of the first small base station when reporting the measurement report;

[0055] The controlling, according to the measurement report, turning on and off the base station function of the second small base station, or adjusting the transmit power when the base station function of the second small base station is turned on, includes:

[0056] Determine an i-th target area where the i-th second small base station is located, with the geographical location of the i-th second small base station as the center, where i is an integer from 1 to N, and N is the number of the second small base stations;

[0057] Acquire a target object whose geographical location is within the i-th target area, wherein the target object includes at least one of a terminal device and a first small base station;

[0058] According to the measurement report of the target object within the i-th target area, the base station function of the i-th second small base station is controlled to be turned on and off, or the transmission power of the base station function of the i-th second small base station is adjusted when it is turned on.

[0059] As can be seen, in the embodiments of the present invention, when a terminal device reports a measurement report, it can also report its current geographic location; and when the first small base station reports a measurement report, it can also report its current geographic location. In this way, the network management device can filter out terminal devices and / or the first small base station within a target area centered on the second small base station based on these geographic locations, and then control the base station function of the second small base station based on the measurement reports of these filtered terminal devices and / or the first small base station.

[0060] Among them, the base station function of the second small base station is controlled according to the measurement report of the terminal device and / or the first small base station within the target area centered on the second small base station, that is, the base station function of the second small base station is controlled according to the measurement report of the terminal device and / or the first small base station located around the second small base station.

[0061] The measurement report can indicate the network coverage situation. Therefore, based on the measurement reports of the terminal devices and / or the first small base station located around the second small base station, the network coverage situation around the second small base station can be understood, so that the control of the base station function of the second small base station is more in line with the network coverage situation around the second small base station (that is, the control of the second small base station is more reasonable and accurate).

[0062] Optionally, the measurement report includes the signal quality of the primary serving cell and the signal quality of multiple neighboring cells of the primary serving cell;

[0063] The controlling, based on the measurement report of the target object within the i-th target area, turning on and off the base station function of the i-th second small base station, or adjusting the transmit power of the i-th second small base station when the base station function is turned on, includes:

[0064] Calculate a first average value of signal qualities of all primary serving cells in the measurement report of the target object;

[0065] Calculating a second average value of signal qualities belonging to the same neighboring area in the measurement report of the target object to obtain multiple second average values;

[0066] According to the first average value and the multiple second average values, the base station function of the i-th second small base station is controlled to be turned on and off, or the transmission power of the base station function of the i-th second small base station when it is turned on is adjusted.

[0067] The signal quality of the primary serving cell and the signal quality of the neighboring cell may be represented by RSRP / SINR.

[0068] For example, when the signal quality of the primary serving cell and the signal quality of the neighboring cell are RSRP, if the target objects within the i-th target area include 10 terminal devices and 2 first small base stations, where each terminal device's geographical location corresponds to a measurement report, and each first small base station's geographical location corresponds to a measurement report, then it is necessary to extract the RSRP of the "primary serving cell" in these measurement reports, calculate the average value, and record it as Q0 (wherein, when calculating Q0 here, it does not matter whether the "primary serving cells" in these measurement reports are the same cell, and the average value is calculated directly); and, for all neighboring cells in these measurement reports, first filter out the RSRP belonging to the same neighboring cell, and then calculate the RSRP average values belonging to the same neighboring cell respectively, and record them as Q1, Q2...Qm, where m is the number of all neighboring cells in these measurement reports.

[0069] It can be seen from this that in an embodiment of the present application, the signal quality of the main service cell and the neighboring cell is extracted from the measurement report of the terminal device and / or the first small base station within the target area centered on the i-th second small base station, and then the above-mentioned average value calculation is performed to obtain the above-mentioned first average value and multiple second average values. These average values can more accurately represent the network coverage around the i-th second small base station, so that the base station function of the i-th second small base station can be more accurately controlled based on the first average value and multiple second average values.

[0070] Optionally, controlling the turning on and off of the base station function of the i-th second small base station according to the first average value and the multiple second average values, or adjusting the transmit power when the base station function of the i-th second small base station is turned on, includes:

[0071] When the first average value is less than the second preset threshold value, and each of the second average values is less than the third preset threshold value, and the base station function of the i-th second small base station is turned off, turning on the base station function of the i-th second small base station;

[0072] When the first average value is less than the second preset threshold value, and each of the second average values is less than the third preset threshold value, and the base station function of the i-th second small base station is turned on, increasing the transmit power of the i-th second small base station when the base station function is turned on;

[0073] When the first average value is greater than or equal to the second preset threshold value, and each of the second average values is greater than or equal to the third preset threshold value, and the base station function of the i-th second small base station is turned on, reduce the transmission power of the i-th second small base station when the base station function is turned on, or turn off the base station function.

[0074] The second preset threshold value and the third preset threshold value may be the same or different.

[0075] For example, the first average value corresponding to the i-th second small base station is recorded as Q0, and the corresponding multiple second average values are recorded as Q1 to Qm. Then, when Q0 is less than the second preset threshold value, and Q1 to Qm are all less than the third preset threshold value, and the base station function of the i-th second small base station is turned off, the base station function of the i-th second small base station can be turned on;

[0076] When Q0 is less than the second preset threshold value, and Q1 to Qm are all less than the third preset threshold value, and the base station function of the i-th second small base station is turned on, the transmission power of the i-th second small base station when the base station function is turned on can be increased;

[0077] When Q0 is greater than or equal to the second preset threshold value, and Q1~Qm are all greater than or equal to the third preset threshold value, and the base station function of the i-th second small base station is turned on, the base station function of the i-th second small base station can be turned off, or the transmission power of the i-th second small base station when the base station function is turned on can be reduced.

[0078] Optionally, increasing or decreasing the transmit power of the i-th second small base station when the base station function is turned on includes:

[0079] Determining target value ranges for the first average value and the plurality of second average values based on a predetermined correspondence between a value range of the signal quality average value and a power value;

[0080] The transmission power of the i-th second small base station when the base station function is turned on is adjusted to the power value corresponding to the target value range in the corresponding relationship.

[0081] That is, in an embodiment of the present invention, the correspondence between the value range of the signal quality average value and the power value is predetermined. For example, the power value corresponding to the value range X1~X2 is Y1, and the power value corresponding to the value range X3~X4 is Y2... Then, if the first average value corresponding to the i-th second small base station is recorded as Q0, and the corresponding multiple second average values are recorded as Q1~Qm, then when Q0, Q1~Qm are all within X1~X2, the transmission power of the i-th second small base station when the base station function is turned on is adjusted to Y1.

[0082] Among them, in the above correspondence, the power values corresponding to the value ranges of different signal quality average values are different. Therefore, if a larger signal quality average value can correspond to a smaller power value, the transmission power of the i-th second small base station when the base station function is turned on can be increased based on the first average value and multiple second average values corresponding to the i-th second small base station; similarly, a smaller signal quality average value can correspond to a larger power value, the transmission power of the i-th second small base station when the base station function is turned on can be reduced based on the first average value and multiple second average values corresponding to the i-th second small base station.

[0083] It is understandable that the specific method for increasing or decreasing the transmission power of the i-th second small base station when the base station function is turned on is not limited to this.

[0084] Figure 3 A flow chart of a small base station control method provided by an embodiment of the present invention is shown. The method can be applied to small base stations, such as Figure 3 As shown, the method may include the following steps:

[0085] Step 301: When the base station function of the small base station is disabled, access the macro base station through the dialing function, and report a measurement report to the macro base station.

[0086] The measurement report includes the signal quality of the primary serving cell and the signal quality of multiple neighboring cells of the primary serving cell. The signal quality can be expressed as RSRP / SINR.

[0087] In addition, in an embodiment of the present invention, when the base station function is disabled, the small base station can access the macro base station (i.e., the macro base station surrounding the small base station) as a terminal device and report a measurement report to the macro base station, which in turn sends the measurement report to the network management device. For example, if the small base station is equipped with a dialing test module, the small base station can access the macro base station through the dialing test function of the dialing test module.

[0088] In addition, the small base station can report a measurement report when it first enters the cell of a predetermined macro base station. The predetermined macro base station can be a base station within a predetermined area. For example, if there are multiple macro base stations within the predetermined area, the small base station will report a measurement report when it first enters the cell of these macro base stations when the base station function is disabled.

[0089] As can be seen from the aforementioned step 301, in an embodiment of the present invention, a small base station can access a macro base station as a terminal device, thereby reporting a measurement report to the macro base station, and then the macro base station forwards the measurement report to the network management device, so that the network management device controls the base station functions of other small base stations based on the measurement report of the first small base station and the measurement reports of multiple terminal devices. Among them, the measurement report can indicate the network coverage situation. Therefore, in an embodiment of the present invention, the small base station can be automatically turned on or off according to the actual network coverage situation, or the transmission power of the small base station when the base station function is turned on can be adjusted. In this way, when the network coverage changes, there is no need to manually remove or install the small base station repeatedly, thereby simplifying the control process of the small base station and saving manpower.

[0090] Optionally, the method further includes:

[0091] Reporting to the macro base station the geographical location of the small base station when generating the measurement report.

[0092] Among them, for the sake of convenience of description, the small base station that reports the measurement report can be called the first small base station, and the small base station to be controlled can be called the second small base station. In an embodiment of the present invention, the first small base station can also report the geographical location at that time when reporting the measurement report, so that the network management device can filter out the terminal devices and / or the first small base station within a target area centered on the second small base station from the terminal devices and the first base station that report the measurement report based on the geographical location and the geographical location when the terminal device reports the measurement report, so as to control the base station function of the second small base station based on the measurement reports of these filtered terminal devices and / or the first small base station.

[0093] It should be noted that the above-mentioned second small base station may include one or more small base stations, and the above-mentioned first small base station may also include one or more small base stations; the base stations included in the above-mentioned first small base station and the second small base station may be the same small base station or different small base stations.

[0094] In summary, the specific implementation of the small base station control method of the embodiment of the present invention can be as follows: Figure 5 As shown, the details are as follows:

[0095] Measurement report collection phase:

[0096] For a terminal device, when it first enters a cell of all base stations within a predetermined area, it reports a measurement report and its geographic location to the base station;

[0097] For small base stations, when the base station function is turned off, the dial-up test module is turned on to dial into the surrounding macro base stations as a terminal device, and report the measurement report and the geographical location of the small base station to the macro base station.

[0098] The measurement report includes the signal quality of the primary serving cell and the signal quality of multiple neighboring cells of the primary serving cell.

[0099] Control phase of small base stations:

[0100] When a predetermined control cycle arrives, the network management device collects the measurement reports within the current cycle and records them as a measurement report set. (That is, the base station function of the small base station is controlled only once within a control cycle to prevent frequent switching of the small base station or frequent power changes.)

[0101] Based on the aforementioned measurement report set, for each small base station within the aforementioned predetermined area, the network management device performs the process of controlling the base station function of the small base station according to the measurement report and the geographical location as described in the following steps H1 to H5 (for ease of description, the small base station reporting the measurement report is referred to as the first small base station, and the small base station to be controlled is referred to as the second small base station):

[0102] Step H1: Determine the i-th target area where the i-th second small base station is located, with the geographical location of the i-th second small base station as the center, where i is an integer from 1 to N, and N is the number of second small base stations;

[0103] Step H2: Acquire a target object whose geographical location is within the i-th target area, where the target object includes at least one of a terminal device and a first small base station;

[0104] Step H3: Calculate the first average value of the signal quality of all primary serving cells in the measurement report of the target object, and record it as Q0;

[0105] Step H4: Calculate the second average value of the signal quality of the same neighboring cell in the measurement report of the target object, and obtain multiple second average values, recorded as Q1 to Qm, where m represents the number of neighboring cells included in the measurement report of the target object;

[0106] Step H5: When Q0 is less than the second preset threshold value, and Q1 to Qm are all less than the third preset threshold value, and the base station function of the i-th second small base station is turned off, the base station function of the i-th second small base station is turned on;

[0107] When Q0 is less than the second preset threshold value, and Q1 to Qm are all less than the third preset threshold value, and the base station function of the i-th second small base station is turned on, increasing the transmission power of the i-th second small base station when the base station function is turned on;

[0108] When Q0 is greater than or equal to the second preset threshold value, and Q1~Qm are all greater than or equal to the third preset threshold value, and the base station function of the i-th second small base station is turned on, turn off the base station function of the i-th second small base station, or reduce the transmission power when the base station function of the i-th second small base station is turned on.

[0109] Among them, the specific method of increasing or decreasing the transmission power of the i-th second small base station when the base station function is turned on can be found in the previous text and will not be repeated here.

[0110] In summary, Figure 4 In the scenario shown, applying the small base station control method of the embodiment of the present invention can achieve the following effects:
