Description

Method and device for identifying and processing adjacent cells

Technical Field

The embodiment of the invention relates to the communication technology, in particular to a method and a device for identifying and processing a neighboring cell.

Background

With the development of mobile internet, the capacity requirement of the wireless cellular network is increasingly strong, so that the wireless cellular network is continuously expanded and upgraded, and the number of frequency points and the types of systems in the same coverage area are more and more. Therefore, how to optimize the distribution of User Equipment (UE) among multiple frequency points and multiple systems to maximize the utilization of spectrum resources is an urgent problem to be solved.

To optimize the distribution of the UE among multiple frequency points and multiple systems, it is first necessary to determine a load sharing neighbor pair. The load-sharing neighboring cell pair is a cell group including at least two cells, the cells in the cell group have a large overlapping area in geographic coverage, and the number of UEs that can be freely switched between the cells in the cell group is sufficient. After determining the load-sharing neighbor cell pair, the network side can perform load balancing in the load-sharing neighbor cell pair, that is, adjust the distribution of the UE in the load-sharing neighbor cell pair, thereby maximally utilizing the spectrum resources.

In the prior art, the load sharing neighbor cell pair is determined manually according to engineering parameters, longitude and latitude information of a site investigation cell, antenna direction angle information and the like, and the manual mode causes large workload and easy error, so that the load balancing cannot be accurately performed.

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.

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Fig. 1 is a schematic flow chart of a first embodiment of a method for identifying and processing a neighboring cell provided by the present invention, where an execution main body of the method may be a neighboring cell identification processing apparatus, and the apparatus may be an independent Network element device, or may be integrated into a Network Management System (NMS for short), an EMS for short, a base station (eNodeB), a base station Controller (BSC for short), a Radio Network Controller (RNC for short), and other devices, as shown in fig. 1, the method includes:

s101, a neighbor cell identification processing device acquires the probability of detecting a pilot frequency and/or a pilot type neighbor cell in a measurement cell; namely, the probability of detecting the pilot frequency adjacent cell in the measuring cell, or the probability of detecting the different-system adjacent cell in the measuring cell, or the probability of detecting the pilot frequency adjacent cell and the different-system adjacent cell is obtained.

Specifically, if the UE in a certain cell serving as the measurement cell detects a pilot frequency and/or inter-system signal and the signal strength is greater than a certain preset value, it is determined that the area is also covered by signals of other neighboring cells, and the signal strength is reported, and then the probability of detecting the pilot frequency and/or inter-system neighboring cell in the measurement cell is calculated according to the number of times that the UE reports the pilot frequency and/or inter-system, where the probability includes: (1) calculating the probability of detecting the pilot frequency adjacent cells in the measuring cells according to the times of reporting the pilot frequency adjacent cells by the UE; in the embodiment of the invention, the pilot frequency adjacent cells can be pilot frequency adjacent cells of the same standard; (2) calculating the probability of detecting the different-mode adjacent cells in the measuring cell according to the times of reporting the different-mode adjacent cells by the UE; (3) and respectively calculating the probability of detecting the pilot frequency adjacent cell and the probability of the different-system adjacent cell in the measurement cell according to the times of reporting the pilot frequency adjacent cell and the different-system adjacent cell by the UE.

S102, the neighbor cell identification processing device determines the measuring cell and the pilot frequency and/or pilot system neighbor cell as a load sharing neighbor cell pair according to the probability; when the probability is greater than a preset threshold, that is, any one of the probability of the inter-frequency neighboring cell and the probability of the inter-system neighboring cell is greater than the preset threshold, it is determined that there is an overlapping coverage area between the corresponding neighboring cell and the measurement cell, and the cells having the overlapping coverage area may be used as a pair of load sharing neighboring cells. Specifically, if the detected probability of the inter-frequency neighboring cell is the probability of the inter-frequency neighboring cell, when the probability of a certain inter-frequency neighboring cell is calculated to be greater than a preset threshold, the inter-frequency neighboring cell and the measurement cell are a pair of load sharing neighboring cells; if the detected probability is the probability of the different-system adjacent cell, when the probability of a certain different-system adjacent cell is calculated to be larger than a preset threshold value, the different-system adjacent cell and the measuring cell are a load sharing adjacent cell pair; if the detected probabilities of the different-frequency adjacent cells and the different-system adjacent cells are respectively determined to be a load sharing adjacent cell pair, namely when the probability of calculating a certain different-system adjacent cell is greater than a preset threshold value, the different-system adjacent cell and the measuring cell are the load sharing adjacent cell pair, and when the probability of calculating a certain different-frequency adjacent cell is greater than the preset threshold value, the different-frequency adjacent cell and the measuring cell are the load sharing adjacent cell pair.

It should be noted that the embodiment of the present invention can be applied to various wireless systems, for example: wideband Code Division Multiple Access (WCDMA), global system for mobile communications (GSM), Long Term Evolution (LTE), Code Division Multiple Access (CDMA) 2000, and the like.

In this embodiment, whether the neighboring cell is a load-sharing neighboring cell pair is determined by the detected inter-frequency and/or inter-system neighboring cell probability, so that the identification of the load-sharing neighboring cell pair is faster and more accurate, and manpower and material resources are saved.

Further, the neighbor cell identification processing apparatus obtains the probability of detecting a different-frequency and/or different-system neighbor cell in a measurement cell, specifically, the neighbor cell identification processing apparatus sends a measurement indication message to at least one user equipment UE in a connected state in the measurement cell, so that the UE detects the different-frequency and/or different-system neighbor cell; then, the neighbor cell identification processing device receives the detection result information of the different-frequency and/or different-system neighbor cell reported by the at least one UE, and acquires the probability according to the detection result information; in a specific implementation process, some UEs in a connected state in the measurement cell need to be selected, and the neighboring cell identification processing apparatus may select the UEs randomly, or may select the UEs for detection according to a certain preset rule. Sending an indication message to the selected UEs to initiate the detection of the adjacent cells with different frequencies and/or different systems, counting the times of initiating the detection in the process, wherein the selected UEs may detect signals with different frequency points and different systems from the cell, reporting the detection results to network side network element equipment, such as a base station (eNodeB), a BSC, an RNC and the like, and reporting the detection results to the adjacent cell identification processing device by the network element equipment, and calculating the probability by the adjacent cell identification processing device according to the detection result information; it should be noted that, when the probability is counted, it is counted according to the same pilot frequency and/or different standard, taking pilot frequency adjacent cells as an example, assuming that the frequency point of the measurement cell is w, indicating at least one UE in a connected state in the measurement cell to initiate multiple detections on all cells adjacent to the measurement cell belonging to the frequency point n, that is, initiating detection on pilot frequency adjacent cells, assuming that according to the reporting of the UEs, the probability of detecting the cell p belonging to the frequency point n and adjacent to the measurement cell is a, and a is greater than a preset threshold, then the cell p and the measurement cell are each a pair of load sharing adjacent cells; in addition, the measuring cell initiates multiple detections on all cells which belong to the frequency point m and are adjacent to the measuring cell, and if the probability of detecting a cell q which belongs to the frequency point m and is adjacent to the measuring cell is b, and b is also greater than a preset threshold, the cell q and the measuring cell are a load sharing adjacent cell pair; if the cell p is used as a measurement cell to initiate multiple detections on all cells which belong to the frequency point m and are adjacent to the cell p, assuming that the probability of detecting the cell q which belongs to the frequency point m and is adjacent to the cell p is c, and c is also greater than a preset threshold value, the cell p and the cell q are adjacent cells for load sharing; that is to say, every two of the measurement cell, the cell p and the cell q are load sharing neighboring cells, and thus the cell p, the cell q and the measurement cell can be considered as a load sharing neighboring cell pair.

For example, in the above example, at least one UE in a connected state in a measurement cell initiates 100 detections to all cells adjacent to the measurement cell belonging to a frequency point n, and the result is found according to a report result of the UE, where the probability a is 90% if the cell p is detected 90 times out of the 100 detections of the cell p.

Further, the neighbor cell identification processing apparatus determines, according to the probability, that the measurement cell and the inter-frequency and/or inter-system neighbor cell are a pair of load sharing neighbor cells, specifically, if the probability is greater than a first threshold, the neighbor cell identification processing apparatus determines that the measurement cell and the inter-frequency and/or inter-system neighbor cell are a pair of load sharing neighbor cells, it should be noted that the first threshold may be set according to experience and a specific application scenario, and the number of cells included in each pair of load sharing neighbor cells is at least two, and may be multiple, as long as each cell meets the above condition.

Fig. 2 is a schematic flow chart of a second embodiment of the method for identifying and processing a neighboring cell provided by the present invention, as shown in fig. 2, after determining that the measurement cell and the inter-frequency and/or inter-format neighboring cell are a load-sharing neighboring cell pair, the neighboring cell identification processing apparatus may further determine whether UE distribution in the load-sharing neighboring cell pair is balanced, and if not, perform distribution balancing processing on the UE in the load-sharing neighboring cell pair, where the specific flow is as follows:

s201, the neighboring cell identification processing apparatus obtains a distribution of UEs in each cell in the load-sharing neighboring cell pair, and specifically, the distribution may be indirectly reflected by any one or a combination of the following: the access times of accessing the UE in each cell from the idle state to the connected state in the load-sharing neighboring cell pair, the switching times of the UE in the connected state in each cell, the resource occupancy rate of each cell, and the like.

S202, the neighboring cell identification processing device determines whether the UE distribution in the load-sharing neighboring cell pair is balanced, specifically, the UE distribution is determined according to the distribution condition, and if balanced, no processing is performed, and if unbalanced, S203 is executed, and if balanced, no processing is performed.

And S203, carrying out distribution balancing processing on the UE in the load sharing neighbor cell pair.

In the specific implementation process of the above flow, the following three specific implementation modes can be provided:

1) in a first mode, determining whether UE distribution in the load-sharing neighboring cell pair is balanced, the method includes: acquiring access times of accessing the UE in each cell of the load-sharing neighbor cell pair from an idle state to a connected state in a preset period, and if the difference between the access times of a first cell and the access times of a second cell is greater than a second threshold value or the difference between the access times of any cell and the average access times of each cell is greater than the second threshold value, determining that the UE in the load-sharing neighbor cell pair is unevenly distributed; wherein, the access times from idle state to connected state of the UE in each cell in the load sharing neighboring cell pair in a period can be obtained in a statistical manner;

in the two methods, no matter which method is adopted to determine that the UE distribution is unbalanced, any method can be adopted to perform distribution balancing processing on the UE in the load-sharing adjacent cell pair, and specifically, (a) at least one UE in an idle state in a cell in the load-sharing adjacent cell pair, wherein the access frequency of the cell is greater than the average value of the access frequency of each cell, is transferred to the rest of the cells, so that the UE distribution of each cell in the load-sharing adjacent cell pair is balanced; in this way, the UEs in idle state in the cells are sequentially transferred to the rest of the cells, and since the access times are periodically obtained and the transfer adjustment is performed on the UEs in each cell according to specific conditions, the distribution of the UEs in each cell is finally balanced;

(b) or transferring at least one UE in an idle state in the first cell to the second cell, so as to balance UE distribution of each cell in the load-sharing neighboring cell pair; in this way, if the load-sharing neighboring cell pair includes more than two cells, two cells are compared and sequentially performed in a cycle, and since the access times are periodically obtained and the transfer adjustment is performed on the UEs in each cell according to specific conditions, the distribution of the UEs in each cell is finally balanced; in this way, if the load-sharing neighboring cell pair includes two cells, at least one UE in an idle state in the first cell is transferred to the second cell, so that the UEs in the two cells are distributed in a balanced manner.

2) In a second manner, it is determined whether the UE distribution in the load-sharing neighboring cell pair is balanced, and the method adopted is as follows: acquiring the switching times of the UE in a connected state in each cell in the load-sharing neighbor cell pair in a preset period, and if the switching times are greater than a third threshold value, determining that the UE in the load-sharing neighbor cell pair is unevenly distributed;

in this way, the UE in the load-sharing neighboring cell pair is subjected to distribution balancing, specifically, at least one UE in an idle state in a handover source cell of the UE is transferred to a handover target cell of the UE, so that the UE distribution of each cell in the load-sharing neighboring cell pair is balanced;

if the number of times of switching is large, it means that the cell of the switching source where the UE is located is overloaded, and some UEs need to be switched to other cells, and this switching of UEs in a connected state may cause signaling waste and cause poor user experience, while the UE in an idle state is transferred without these problems.

3) In a third manner, similar to the first manner, it is determined whether the UE distribution in the load-sharing neighboring cell pair is balanced, and the method adopted is as follows: acquiring the resource occupancy rate of each cell in the load-sharing neighbor cell pair in a preset period, and if the difference value between the resource occupancy rate of the first cell and the resource occupancy rate of the second cell is greater than a fourth threshold value between any two cells, or the difference value between the access frequency of any cell and the average value of the resource occupancy rates of each cell is greater than the fourth threshold value, determining that the UE distribution in the load-sharing neighbor cell pair is unbalanced; it should be noted that the resource occupancy rate may be a utilization rate of an air interface resource, or a utilization rate of a timeslot resource, and the like;

in the two methods, no matter which method is adopted to determine that the UE distribution is unbalanced, any method can be adopted to perform distribution balancing processing on the UE in the load-sharing adjacent cell pair, and specifically, (a) at least one UE in an idle state in a cell of the load-sharing adjacent cell pair, of which the resource occupancy rate is greater than the average resource occupancy rate of each cell, is transferred to the rest of the cells, so that the UE distribution of each cell in the load-sharing adjacent cell pair is balanced; in this way, the resource occupancy rate is periodically obtained, and the UE in each cell is transferred according to specific conditions, so that the UE distribution balance of each cell is finally achieved;

(b) transferring at least one UE in an idle state in the first cell to the second cell to balance the distribution of the UE in each cell in the load sharing neighbor cell pair, wherein in the mode, if the load sharing neighbor cell pair comprises more than two cells, the two cells are compared and are sequentially and circularly performed, and as the resource occupancy rate is periodically obtained, the UE in each cell is transferred according to specific conditions, the distribution of the UE in each cell is finally balanced; in this way, if the load-sharing neighboring cell pair includes two cells, at least one UE in an idle state in the first cell is transferred to the second cell, so that the UEs in the two cells are distributed in a balanced manner.

It should be noted that, the above three ways are not limited; in the above three modes, the second threshold, the third threshold, and the fourth threshold are set according to experience and specific application scenarios.
