本发明实施例涉及通信技术领域，尤其涉及一种多载波负荷均衡的方法、装置、核心网设备和存储介质。The embodiments of the present invention relate to the technical field of communications, and in particular to a method, device, core network equipment and storage medium for multi-carrier load balancing.
背景技术Background technique
随着移动网络的快速发展，用户对扩大网络容量的需求日益提高。传统的网络扩容通常采用同厂家的设备进行多载波扩容，当采用异厂家设备时，由于异厂家设备接入的基站不同，无法实现自动有效的负荷均衡，由此可能会造成同一扇区的不同小区之间负载不平衡的问题。With the rapid development of mobile networks, users' requirements for expanding network capacity are increasing day by day. Traditional network expansion usually uses equipment from the same manufacturer for multi-carrier expansion. When using equipment from different manufacturers, automatic and effective load balancing cannot be achieved due to the different base stations accessed by equipment from different manufacturers. The problem of load imbalance among cells.
现有的负荷均衡方法主要是在多载波同覆盖的环境下，应用于同厂家设备覆盖的小区之间，即同厂家设备覆盖的小区可以接入相同基站，通过基站的协调将同一基站下负载高的小区中部分用户转移到负载低的小区，平衡异频或异系统之间的负载。The existing load balancing method is mainly applied between the cells covered by the equipment of the same manufacturer in the environment of multi-carriers with the same coverage, that is, the cells covered by the equipment of the same manufacturer can access the same base station, and the load of the same base station will be lowered through the coordination of the base stations. Some users in high-load cells are transferred to low-load cells to balance the load between different frequencies or different systems.
然而，现有的负荷均衡方法无法直接应用于异厂家设备扩容后的负荷调整，且上述方法在实现过程中，同覆盖范围的不同小区利用多载波的概率是相同的，这种垂直分层的覆盖方式会导致小区用户在多载波之间频繁异频切换，网络资源利用率低，用户体验不够好。However, the existing load balancing method cannot be directly applied to the load adjustment after the expansion of equipment from different manufacturers, and in the implementation process of the above method, the probability of using multiple carriers in different cells with the same coverage is the same. The coverage mode will cause users in the cell to frequently switch between multiple carriers, resulting in low utilization of network resources and poor user experience.

下面对本发明实施例的应用场景进行解释：The application scenarios of the embodiments of the present invention are explained below:
图1为本发明实施例提供的多载波负荷均衡方法的一种应用场景图,如图1所示，本发明实施例提供的多载波负荷均衡系统包括：核心网11，与核心网相连的基站12和基站13，基站12和基站13的扇区14覆盖第一小区15和第二小区16。其中，核心网11可以是运营商构建的网络子系统的一部分，可以与多个不同基站(本发明实施例中核心网与两个不同基站)进行通信，其主要功能是提供用户连接、对用户的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。基站12和基站13在物理位置上可以完全相同，基站的天线覆盖的区域为一个基站扇区，基站12和基站13采用异厂家的设备构成。通常，一个基站扇区可能包含多个采用不同载波进行通信但覆盖方向相同的小区，上述多个小区称为同覆盖异频小区对。例如：扇区14覆盖第一小区15和第二小区16，第一小区15采用载波频率1进行通信，第二小区16采用载波频率2进行通信。假设载波频率1大于载波频率2，则配置第一小区15为高优先级小区，配置第二小区16为低优先级小区，由于高优先级小区的覆盖能力弱于低优先级小区，因此近端用户驻留在高优先级小区，远端用户驻留在低优先级小区。Fig. 1 is an application scene diagram of the multi-carrier load balancing method provided by the embodiment of the present invention. As shown in Fig. 1, the multi-carrier load balancing system provided by the embodiment of the present invention includes: a
本发明实施例的一种应用场景可以为，高优先级小区和低优先级小区组成一个同覆盖异频小区对，高优先级小区和低优先级小区分别接入多个不同的用户，两个小区各自的用户数量会由于通信环境、用户操作和用户位置等变化而发生改变，例如：当用户位置发生改变，用户由近端用户变为远端用户时，其驻留小区会由高优先级小区变为低优先级小区，则高优先级小区的用户数量会增加，低优先级小区的用户数量会减少；当低优先级小区中的某个用户执行关机操作，则低优先级小区的用户数量会减少；当外界通信信道发生改变，造成用户的接收信号参考功率发生变化时，也可能会造成用户改变接入的小区。上述通信环境、用户操作和用户位置的变化将导致基站参数发生变化，该参数包括根据基站覆盖的小区对的小区数据和参数计算所得的初始门限值。由于高优先级小区和低优先级小区接入的基站不同，不同基站之间的小区数据和参数无法共享，而通过核心网可以获得不同基站覆盖的小区对的小区数据和参数。因此，在核心网中，首先，根据获取的同覆盖异频小区对的小区数据和参数确定各基站对应的第一初始门限值和第二初始门限值，该小区数据和参数可以从核心网侧的数据库中获取，该数据库可以是运营商建立和维护的公共网管平台；其次，根据各小区的负载数据判断扇区的负荷是否均衡，该负载数据可以是核心网侧数据库中的小区负荷表征参数，根据小区负荷表征参数判断扇区的负荷是否均衡，若确定扇区的负荷不均衡，则根据第一初始门限值和第二初始门限值确定对应的门限调整值；然后，判断对应的门限调整值是否满足扇区负荷调整条件，若对应的门限调整值满足扇区负荷调整条件，则核心网将门限调整值发给各基站，以使基站对扇区的负荷进行调整，也即各基站将门限初始值更新为门限调整值，基站所属的用户根据门限调整值确定是否进行小区的切换，最终使得扇区的负荷达到均衡。An application scenario of the embodiment of the present invention may be that a high-priority cell and a low-priority cell form a cell pair with the same coverage and different frequencies, and the high-priority cell and the low-priority cell respectively access multiple different users. The number of users in each cell will change due to changes in the communication environment, user operations, and user location. For example, when the user location changes and the user changes from a near-end user to a far-end user, the cell where it resides will change from high priority to When a cell becomes a low-priority cell, the number of users in the high-priority cell will increase, and the number of users in the low-priority cell will decrease; when a user in the low-priority The number will decrease; when the external communication channel changes, causing the user's received signal reference power to change, it may also cause the user to change the cell to be accessed. The above-mentioned changes in communication environment, user operation and user location will lead to changes in base station parameters, which include initial thresholds calculated based on cell data and parameters of cell pairs covered by the base station. Since the base stations accessed by high-priority cells and low-priority cells are different, cell data and parameters between different base stations cannot be shared, and cell data and parameters of cell pairs covered by different base stations can be obtained through the core network. Therefore, in the core network, firstly, the first initial threshold value and the second initial threshold value corresponding to each base station are determined according to the acquired cell data and parameters of the same-coverage inter-frequency cell pair, and the cell data and parameters can be obtained from the core The database can be obtained from the database on the network side, which can be the public network management platform established and maintained by the operator; secondly, according to the load data of each cell to determine whether the load of the sector is balanced, the load data can be the cell load in the database on the core network side characterizing parameters, judging whether the load of the sector is balanced according to the characterizing parameter of the cell load, if it is determined that the load of the sector is unbalanced, then determining the corresponding threshold adjustment value according to the first initial threshold value and the second initial threshold value; then, judging Whether the corresponding threshold adjustment value satisfies the sector load adjustment condition, if the corresponding threshold adjustment value meets the sector load adjustment condition, the core network sends the threshold adjustment value to each base station so that the base station can adjust the sector load, and also That is, each base station updates the initial threshold value to the threshold adjustment value, and the users belonging to the base station determine whether to perform cell handover according to the threshold adjustment value, so that the load of the sectors is finally balanced.
本发明实施例提供的多载波负荷均衡方法，通过在核心网侧获取不同基站的扇区覆盖的异厂家小区对的小区数据和参数设置初始门限值，根据对小区对的负荷均衡情况进行判断的结果进行初始门限值的调整，从而使得采用异厂家设备的同一扇区的不同小区之间能够自动实现负荷均衡，提高了网络资源利用率，避免了用户在异频小区之间频繁切换，提升了用户体验。The multi-carrier load balancing method provided by the embodiment of the present invention obtains the cell data and parameters of the cell pairs of different manufacturers covered by the sectors of different base stations on the core network side, sets the initial threshold value, and judges according to the load balancing situation of the cell pairs Adjust the initial threshold value according to the results, so that load balancing can be automatically realized between different cells in the same sector using equipment from different manufacturers, which improves the utilization of network resources and avoids frequent switching between different frequency cells by users. Improved user experience.
下面以具体地实施例对本发明的技术方案以及本发明的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本发明的实施例进行描述。The technical solution of the present invention and how the technical solution of the present invention solves the above technical problems will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
图2为本发明实施例一提供的多载波负荷均衡方法的流程图，如图2所示，本实施例提供的多载波负荷均衡方法包括以下几个步骤。FIG. 2 is a flowchart of a multi-carrier load balancing method provided in Embodiment 1 of the present invention. As shown in FIG. 2 , the multi-carrier load balancing method provided in this embodiment includes the following steps.
步骤101，确定各基站对应的第一初始门限值和第二初始门限值。Step 101, determining a first initial threshold value and a second initial threshold value corresponding to each base station.
其中，第一初始门限值和第二初始门限值为根据基站覆盖的部分小区数据和参数计算得到，用于调整基站的扇区覆盖的小区对的负荷。小区数据和参数可以包括：物理资源块(PRB)利用率、平均用户数、平均信号强度、小区最低接入电平。Wherein, the first initial threshold value and the second initial threshold value are calculated according to data and parameters of some cells covered by the base station, and are used to adjust the load of the cell pair covered by the sector of the base station. Cell data and parameters may include: physical resource block (PRB) utilization rate, average number of users, average signal strength, and minimum cell access level.
本实施例中，核心网获取小区数据和参数并根据该小区数据和参数计算第一初始门限值和第二初始门限值，再将第一初始门限值和第二初始门限值下发给两个基站，基站可根据接收到的第一初始门限值和第二初始门限值更新基站对应的第一初始门限值和第二初始门限值。In this embodiment, the core network obtains the cell data and parameters, calculates the first initial threshold and the second initial threshold according to the cell data and parameters, and then lowers the first initial threshold and the second initial threshold to Send the information to the two base stations, and the base station may update the first initial threshold and the second initial threshold corresponding to the base station according to the received first initial threshold and the second initial threshold.
可以理解的是，基站也可以不更新核心网下发的第一初始门限值和第二初始门限值，而是继续保持基站原有的门限值。原有的门限值指基站在满足当前小区对的小区用户正常通信的情况下的门限值。该门限值包括：服务频点低优先级重选门限和异频频点高优先级重选门限。It can be understood that the base station may not update the first initial threshold value and the second initial threshold value issued by the core network, but continue to maintain the original threshold value of the base station. The original threshold value refers to the threshold value of the base station under the condition that the cell users of the current cell pair can communicate normally. The threshold value includes: a low-priority reselection threshold of a service frequency point and a high-priority reselection threshold of an inter-frequency point.
步骤102，根据各小区的负载数据判断扇区的负荷是否均衡。Step 102, judging whether the sector load is balanced according to the load data of each cell.
其中，负载数据可以为小区的平均PRB利用率，也可以为小区用户平均负荷量，还可以用其他小区参数表示，此处不做具体限定。扇区的负荷是否均衡是指扇区所覆盖的异频小区对之间的负荷是否达到负荷均衡。The load data may be the average PRB utilization rate of the cell, or the average load of users in the cell, or may be represented by other cell parameters, which are not specifically limited here. Whether the sector load is balanced refers to whether the load among the inter-frequency cell pairs covered by the sector reaches load balance.
具体地，本实施例中，判断扇区的负荷是否均衡可以通过判断同覆盖异频小区对的两个小区的平均PRB利用率的差值来实现。Specifically, in this embodiment, judging whether the sector load is balanced may be realized by judging the difference between the average PRB utilization rates of two cells of the same coverage inter-frequency cell pair.
步骤103，若确定扇区的负荷不均衡，则根据第一初始门限值和第二初始门限值确定对应的门限调整值。Step 103, if it is determined that the loads of the sectors are unbalanced, then determine a corresponding threshold adjustment value according to the first initial threshold value and the second initial threshold value.
其中，门限调整值是指高优先级小区用户向低优先小区转移的门限值，或者低优先级小区用户向高优先小区转移的门限值。Wherein, the threshold adjustment value refers to a threshold value for a user in a high-priority cell to transfer to a low-priority cell, or a threshold value for a user in a low-priority cell to transfer to a high-priority cell.
具体地，本实施例中，当同扇区同覆盖异频小区对之间的负荷不均衡时，根据第一初始门限值和第二初始门限值计算得到的门限调整值可以用于调整小区对之间的负荷，使得高优先级小区和低优先级小区之间的负荷基本均衡。Specifically, in this embodiment, when the load between the same-sector and same-coverage inter-frequency cell pair is unbalanced, the threshold adjustment value calculated according to the first initial threshold value and the second initial threshold value can be used to adjust The load between the cell pairs makes the load between the high-priority cell and the low-priority cell basically balanced.
步骤104，根据对应的门限调整值判断是否满足扇区负荷调整条件。Step 104, judging whether the sector load adjustment condition is satisfied according to the corresponding threshold adjustment value.
其中，判断是否满足扇区负荷调整条件是指判断步骤103中计算得到的门限调整值是否超出扇区用户平均信号强度，该扇区用户平均信号强度可根据小区数据进行计算。Wherein, judging whether the sector load adjustment condition is met refers to judging whether the threshold adjustment value calculated in step 103 exceeds the average signal strength of users in the sector, and the average signal strength of users in the sector can be calculated according to cell data.
步骤105，若对应的门限调整值满足扇区负荷调整条件，则将门限调整值发给各基站，以使基站对扇区的负荷进行调整。Step 105, if the corresponding threshold adjustment value satisfies the sector load adjustment condition, send the threshold adjustment value to each base station, so that the base station adjusts the sector load.
具体地，本实施例中，如果门限调整值未超出扇区用户平均信号强度，则核心网将该门限调整值下发给各基站，并更新小区参数中的门限值，同时各基站将根据核心网下发的门限调整值对用户进行调整，即，用户根据测量到的基站门限值与接收信号参考功率进行比较，若高优先级小区用户测量的高优先级小区的接收信号参考功率小于基站门限值，则高优先级小区用户转移至低优先级小区；或者若低优先级小区用户测量的高优先级小区的接收信号参考功率大于基站门限值，则低优先级小区用户转移至高优先级小区，最终使得高优先级小区和低优先级小区的负荷基本达到均衡。Specifically, in this embodiment, if the threshold adjustment value does not exceed the average signal strength of sector users, the core network will send the threshold adjustment value to each base station, and update the threshold value in the cell parameter, and each base station will be based on The threshold adjustment value issued by the core network adjusts the user. That is, the user compares the measured threshold value of the base station with the received signal reference power. If the received signal reference power of the high-priority cell measured by the high-priority cell user is less than If the threshold value of the base station is higher than the threshold value of the base station, the users in the high-priority cell will be transferred to the low-priority cell; The priority cell finally makes the load of the high priority cell and the low priority cell basically reach a balance.
本发明实施例提供一种多载波负荷均衡方法，应用于核心网设备，核心网设备与在同一扇区内的两个不同基站通信，扇区包括同覆盖异频小区对，方法包括：确定各基站对应的第一初始门限值和第二初始门限值；根据各小区的负载数据判断扇区的负荷是否均衡；若确定扇区的负荷不均衡，则根据第一初始门限值和第二初始门限值确定对应的门限调整值；根据对应的门限调整值判断是否满足扇区负荷调整条件；若对应的门限调整值满足扇区负荷调整条件，则将门限调整值发给各基站，以使基站对扇区的负荷进行调整。本发明实施例通过根据小区数据和小区参数计算分层初始值并建立初始门限值，对小区之间的负载均衡情况进行判断，并依据判断结果进行门限值的调整，使得采用异厂家设备的同一扇区的不同小区之间能够自动实现负荷均衡，提高了网络资源利用率，避免了用户在异频小区之间频繁切换，提升了用户体验。An embodiment of the present invention provides a multi-carrier load balancing method, which is applied to core network equipment.

图3为本发明实施例二提供的多载波负荷均衡方法的流程图，如图3所示，本发明实施例提供的多载波负荷均衡方法，是在实施例二的基础上对步骤101至步骤105进一步细化，包括以下几个步骤。Fig. 3 is a flow chart of the multi-carrier load balancing method provided by Embodiment 2 of the present invention. As shown in Fig. 3 , the multi-carrier load balancing method provided by the embodiment of the present invention is to step 101 to step 101 on the basis of Embodiment 2. Step 105 is further refined, including the following steps.
步骤201，确定各基站对应的第一初始门限值和第二初始门限值。Step 201, determining a first initial threshold value and a second initial threshold value corresponding to each base station.
可选地，步骤201包括以下步骤：Optionally, step 201 includes the following steps:
步骤2011，获取小区对中各小区的小区数据和小区参数。Step 2011, acquiring cell data and cell parameters of each cell in the cell pair.
步骤2012，根据小区数据计算分层初始值。Step 2012, calculate the initial layered value according to the cell data.
步骤2013，根据分层初始值对小区参数进行初始化参数配置，以得到第一初始门限值和第二初始门限值。Step 2013, perform initialization parameter configuration on the cell parameters according to the layered initial value, so as to obtain the first initial threshold value and the second initial threshold value.
可选地，步骤2013包括以下几个步骤：Optionally, step 2013 includes the following steps:
步骤20131，配置第一初始门限调整步长。Step 20131, configure the first initial threshold adjustment step.
步骤20132，将分层初始值与初始门限调整步长之和配置为第一初始门限值。Step 20132, configure the sum of the layered initial value and the initial threshold adjustment step as the first initial threshold.
步骤20133，将分层初始值与预设初始门限调整步长之差配置为第二初始门限值。Step 20133, configure the difference between the layered initial value and the preset initial threshold adjustment step as the second initial threshold value.
具体地，本实施例中，首先，通过运营商的公共网管平台获取同覆盖异频小区对各小区的数据和参数，建立小区数据参数库。该小区数据参数库的小区数据包括：小区ID号(驻留小区的标识编码)、PRB利用率、平均用户数、平均信号强度、小区最低接入电平。上述小区数据根据运营商的需求定时进行更新。该小区数据参数库的小区参数包括：服务频点低优先级重选门限和异频频点高优先级重选门限。Specifically, in this embodiment, firstly, the data and parameters of the same-coverage and different-frequency cells for each cell are obtained through the public network management platform of the operator, and a cell data parameter library is established. The cell data in the cell data parameter database includes: cell ID number (identification code of the cell where the cell resides), PRB utilization rate, average number of users, average signal strength, and the lowest access level of the cell. The above cell data is regularly updated according to the needs of operators. The cell parameters in the cell data parameter database include: a low priority reselection threshold of a service frequency point and a high priority reselection threshold of a different frequency point.
其次，根据已建立的小区数据参数库中的小区数据计算分层初始值，具体计算方法如下：Secondly, calculate the layered initial value according to the cell data in the established cell data parameter library, the specific calculation method is as follows:
根据实施例一中应用场景的介绍，定义低优先级小区和高优先级小区的平均PRB利用率分别为Pa和Pb，平均用户数为Na和Nb，平均信号强度为Ra和Rb，则有，单用户平均PRB利用率为According to the introduction of the application scenario in Embodiment 1, the average PRB utilization rates of the low-priority cell and the high-priority cell are defined as Pa and Pb respectively, the average number of users is Naand Nb , and the average signal strength is Ra and Rb , then there is, and the average PRB utilization of a single user is
Sa＝Pa/Na，Sb＝Pb/NbSa = Pa /Na , Sb = Pb /Nb
由于不同距离的单用户PRB利用率不同，近端用户资源开销较低，远端用户资源开销较高，为合理均衡不同载波小区之间的负荷，结合扇区下的用户数据，计算得出分层初始值Rs：Due to the different PRB utilization rates of single users at different distances, the resource overhead of near-end users is relatively low, while the resource overhead of far-end users is relatively high. Layer initial value Rs :
Rs＝Ra×Na×Sa/(Sa+Sb)+Rb×Nb×Sb/(Sa+Sb)Rs ＝Ra ×Na ×Sa /(Sa +Sb )+Rb ×Nb ×Sb /(Sa +Sb )
最后，配置第一初始门限调整步长为l，根据分层初始值对小区参数进行初始化参数配置，得到第一初始门限值和第二初始门限值，计算公式如下所示：Finally, the first initial threshold adjustment step is configured as 1, and the cell parameters are initialized according to the layered initial value to obtain the first initial threshold value and the second initial threshold value. The calculation formula is as follows:
第一初始门限值＝Rs+l (1)The first initial threshold = Rs +l (1)
第二初始门限值＝Rs-l (2)The second initial threshold value = Rs -l (2)
其中，Rs为分层初始值，l的取值为2，需要说明的是l也可以取值为1或3。只要满足第一初始门限值和第二初始门限值构成的缓冲区间的范围适中即可。Among them, Rs is the initial value of the layer, and the value of l is 2. It should be noted that l can also take the value of 1 or 3. As long as the range between the buffers formed by the first initial threshold and the second initial threshold is satisfied, it is sufficient.
步骤202，判断高优先级小区和低优先级小区之间的负荷是否均衡。Step 202, judging whether the load between the high-priority cell and the low-priority cell is balanced.
具体地，本实施例中，若Pa与pb之间的差值的绝对值小于负荷均衡阈值，则认为高优先级小区和低优先级小区之间的负荷均衡，否则认为高优先级小区和低优先级小区之间的负荷不均衡，该负荷均衡阈值可以为30％，或其他适宜数值，例如：25％，本实施例中对此不作具体限定。Specifically, in this embodiment, if the absolute value of the difference between Pa and pb is smaller than the load balancing threshold, it is considered that the load between the high priority cell and the low priority cell is balanced, otherwise it is considered that the high priority cell and the low priority cell are balanced. For load imbalance among priority cells, the load balance threshold may be 30%, or other appropriate values, such as 25%, which is not specifically limited in this embodiment.
根据判断结果，当高优先级小区和低优先级小区之间的负荷均衡时，执行步骤210；否则当高优先级小区和低优先级小区之间的负荷不均衡时，执行步骤203。According to the judgment result, when the load between the high-priority cell and the low-priority cell is balanced, perform step 210; otherwise, when the load between the high-priority cell and the low-priority cell is unbalanced, perform step 203.
步骤203，设置第二初始门限调整步长。Step 203, setting a second initial threshold adjustment step size.
具体地，本实施例中，设置第二初始门限调整步长为p。其中，p的取值为1,需要说明的是，p的取值也可以根据实际需求进行调整，例如：若高优先级小区的负荷与低优先级小区的负荷差值较大，则p的取值可以适当扩大，即p取值为2。Specifically, in this embodiment, the second initial threshold adjustment step size is set to p. Among them, the value of p is 1. It should be noted that the value of p can also be adjusted according to actual needs. For example: if the load difference between the high priority cell and the low priority cell is large, the value of p The value can be expanded appropriately, that is, the value of p is 2.
步骤204，判断高优先级小区的负荷是否大于低优先级小区的负荷，若是，则执行步骤205，否则执行步骤206。Step 204, judging whether the load of the high-priority cell is greater than the load of the low-priority cell, if yes, execute
步骤205，根据第一初始门限值、第二初始门限值和第二初始门限调整步长确定对应的第一门限调整值和第二门限调整值。Step 205: Determine a corresponding first threshold adjustment value and a second threshold adjustment value according to the first initial threshold value, the second initial threshold value, and the second initial threshold adjustment step size.
具体地，本实施例中，第一门限调整值和第二门限调整值的计算公式如下：Specifically, in this embodiment, the calculation formulas of the first threshold adjustment value and the second threshold adjustment value are as follows:
第一门限调整值＝Rs+l+p (3)First threshold adjustment value=Rs +l+p (3)
第二门限调整值＝Rs-l+p (4)The second threshold adjustment value = Rs -l+p (4)
其中，Rs为分层初始值，l为第一初始门限调整步长，p为第二初始门限调整步长。Among them, Rs is the initial value of the layer, l is the first initial threshold adjustment step size, and p is the second initial threshold adjustment step size.
步骤206，根据第一初始门限值、第二初始门限值和第二初始门限调整步长确定对应的第三门限调整值和第四门限调整值。Step 206: Determine a corresponding third threshold adjustment value and a fourth threshold adjustment value according to the first initial threshold value, the second initial threshold value, and the second initial threshold adjustment step size.
具体地，本实施例中，第三门限调整值和第四门限调整值的计算公式如下：Specifically, in this embodiment, the calculation formulas of the third threshold adjustment value and the fourth threshold adjustment value are as follows:
第三门限调整值＝Rs+l-p (5)The third threshold adjustment value=Rs +lp (5)
第四门限调整值＝Rs-l-p (6)Fourth threshold adjustment value = Rs -lp (6)
其中，Rs为分层初始值，l为第一初始门限调整步长，p为第二初始门限调整步长。Among them, Rs is the initial value of the layer, l is the first initial threshold adjustment step size, and p is the second initial threshold adjustment step size.
步骤203-步骤206是根据第一初始门限值和第二初始门限值确定对应的门限调整值的一种可选实施方式。Steps 203 to 206 are an optional implementation manner of determining a corresponding threshold adjustment value according to the first initial threshold value and the second initial threshold value.
步骤207，判断对应的门限调整值是否满足扇区负荷调整条件，若是，执行步骤209，否则，执行步骤208。Step 207, judging whether the corresponding threshold adjustment value satisfies the sector load adjustment condition, if yes, execute step 209, otherwise, execute step 208.
可选地，步骤207包括以下步骤：Optionally, step 207 includes the following steps:
步骤2071，判断对应的门限调整值是否小于预设负荷调整阈值；Step 2071, judging whether the corresponding threshold adjustment value is smaller than the preset load adjustment threshold;
步骤2072，若确定对应的门限调整值小于预设负荷调整阈值，则确定满足扇区负荷调整条件；Step 2072, if it is determined that the corresponding threshold adjustment value is smaller than the preset load adjustment threshold, then determine that the sector load adjustment condition is met;
步骤2073，若确定对应的门限调整值大于预设负荷调整阈值，则确定不满足扇区负荷调整条件。Step 2073, if it is determined that the corresponding threshold adjustment value is greater than the preset load adjustment threshold, it is determined that the sector load adjustment condition is not satisfied.
具体地，本实施例中，根据步骤201中的小区数据和小区参数预设负荷调整阈值，即扇区用户平均信号强度
若第一门限调整值和第二门限调整值不大于扇区用户平均信号强度，则满足扇区负荷调整条件，或者若第三门限调整值和第四门限调整值不大于扇区用户平均信号强度，则满足扇区负荷调整条件，执行步骤209。上述第一门限调整值和第二门限调整值的判断与第三门限调整值和第四门限调整值的判断分属两种不同的情况，实际判断中仅会处理其中一种情况。If the first threshold adjustment value and the second threshold adjustment value are not greater than the sector user average signal strength, then the sector load adjustment condition is met, or if the third threshold adjustment value and the fourth threshold adjustment value are not greater than the sector user average signal strength , then the sector load adjustment condition is met, and step 209 is executed. The judgment of the above-mentioned first threshold adjustment value and the second threshold adjustment value and the judgment of the third threshold adjustment value and the fourth threshold adjustment value belong to two different cases, and only one of the cases will be dealt with in the actual judgment.
若第一门限调整值和第二门限调整值大于扇区用户平均信号强度，则不满足扇区负荷调整条件，或者若第三门限调整值和第四门限调整值大于扇区用户平均信号强度，则不满足扇区负荷调整条件，执行步骤208。同样的，上述第一门限调整值和第二门限调整值的判断与第三门限调整值和第四门限调整值的判断分属两种不同的情况，实际判断中仅会处理其中一种情况。If the first threshold adjustment value and the second threshold adjustment value are greater than the sector user average signal strength, the sector load adjustment condition is not satisfied, or if the third threshold adjustment value and the fourth threshold adjustment value are greater than the sector user average signal strength, If the sector load adjustment condition is not satisfied, step 208 is executed. Similarly, the determination of the first threshold adjustment value and the second threshold adjustment value and the determination of the third threshold adjustment value and the fourth threshold adjustment value belong to two different situations, and only one of them will be dealt with in the actual judgment.
步骤208，向维护用户终端发送参数调整超出范围确认消息，以使维护用户根据调整超出范围确认消息上站核查。Step 208: Send a parameter adjustment out-of-range confirmation message to the maintenance user terminal, so that the maintenance user can check on the station according to the adjustment out-of-range confirmation message.
具体地，本实施例中，当门限调整值超出扇区用户平均信号强度时，核心网向维护用户终端发送参数调整超出范围确认消息，该消息可以直接显示在维护用户终端的界面上，也可以通过预先设置的报警音提示用户参数调整超出范围，此处不做限定。维护用户知悉参数调整超出范围后，需要上站核查，检查设备是否存在故障或者小区对是否为同覆盖异频小区对。Specifically, in this embodiment, when the threshold adjustment value exceeds the average signal strength of sector users, the core network sends a parameter adjustment out-of-range confirmation message to the maintenance user terminal, and the message can be directly displayed on the interface of the maintenance user terminal, or can be The preset alarm sound is used to prompt the user that the parameter adjustment is out of range, which is not limited here. After the maintenance user knows that the parameter adjustment is out of range, he needs to go to the station to check whether there is a fault in the equipment or whether the cell pair is a cell pair with the same coverage and different frequencies.
步骤209，核心网下发参数调整指令，更新小区数据参数库中的门限值，间隔时间T1后，重新取数，返回步骤202。Step 209 , the core network issues a parameter adjustment command to update the threshold value in the cell data parameter library, after an interval of T1 , refetch the value, and return to step 202 .
可选地，根据第一初始门限值、第二初始门限值和第二初始门限调整步长确定对应的第一门限调整值和第二门限调整值，包括：Optionally, determining a corresponding first threshold adjustment value and a second threshold adjustment value according to the first initial threshold value, the second initial threshold value, and the second initial threshold adjustment step size includes:
将第一初始门限值和第二初始门限调整步长之和确定为对应的第一门限调整值；determining the sum of the first initial threshold value and the second initial threshold adjustment step as a corresponding first threshold adjustment value;
将第二初始门限值和第二初始门限调整步长之和确定为对应的第二门限调整值。The sum of the second initial threshold value and the second initial threshold adjustment step size is determined as a corresponding second threshold adjustment value.
具体地，本实施例中，根据步骤205中的公式(3)和公式(4)，核心网将第一门限调整值和第二门限调整值下发给基站12和基站13，同时将小区数据参数库中的第一初始门限值和第二初始门限值更新为第一门限调整值和第二门限调整值，则基站所属小区用户通过测量可以获知驻留小区和相邻小区的基站参数，即第一门限调整值和第二门限调整值，同时小区用户会测量驻留小区和目标小区的接收信号参考功率，并根据第一门限调整值和第二门限调整值以及接收信号参考功率决定是否接入其他小区。Specifically, in this embodiment, according to the formula (3) and formula (4) in
例如：在高优先级小区与低优先级小区之间的负荷不均衡且高优先级小区负荷大于低优先级小区负荷的场景下，当高优先级小区用户测量的高优先级小区的接收信号参考功率小于第二门限调整值时，高优先级小区用户转移至低优先级小区，使得高优先级小区用户数量减少，低优先级小区用户数量增加，进而使得高优先级小区的负荷减少，低优先级小区的负荷增加，最终两个小区之间的负荷基本达到平衡。For example: in the scenario where the load between the high priority cell and the low priority cell is unbalanced and the load of the high priority cell is greater than the load of the low priority cell, when the received signal of the high priority cell measured by the high priority cell When the power is less than the second threshold adjustment value, the users in the high-priority cell are transferred to the low-priority cell, so that the number of users in the high-priority cell decreases and the number of users in the low-priority cell increases, thereby reducing the load of the high-priority The load of the secondary cell increases, and finally the load between the two cells basically reaches a balance.
可选地，根据第一初始门限值、第二初始门限值和第二初始门限调整步长确定对应的第三门限调整值和第四门限调整值，包括：Optionally, determining a corresponding third threshold adjustment value and a fourth threshold adjustment value according to the first initial threshold value, the second initial threshold value, and the second initial threshold adjustment step size, including:
将第一初始门限值和第二初始门限调整步长之差确定为对应的第三门限调整值；determining the difference between the first initial threshold value and the second initial threshold adjustment step as a corresponding third threshold adjustment value;
将第二初始门限值和第二初始门限调整步长之差确定为对应的第四门限调整值。The difference between the second initial threshold value and the second initial threshold adjustment step is determined as a corresponding fourth threshold adjustment value.
具体地，本实施例中，根据步骤206中的公式(5)和公式(6)，核心网将第三门限调整值和第四门限调整值下发给基站12和基站13，同时将小区数据参数库中的第一初始门限值和第二初始门限值更新为第三门限调整值和第四门限调整值，则基站所属小区用户通过测量可以获知驻留小区和相邻小区的基站参数，即第三门限调整值和第四门限调整值，同时小区用户会测量驻留小区和目标小区的接收信号参考功率，并根据第三门限调整值和第四门限调整值以及接收信号参考功率决定是否接入其他小区。Specifically, in this embodiment, according to the formula (5) and formula (6) in step 206, the core network sends the third threshold adjustment value and the fourth threshold adjustment value to the
例如：在高优先级小区与低优先级小区之间的负荷不均衡且高优先级小区负荷小于低优先级小区负荷的场景下，当低优先级小区用户测量的高优先级小区的接收信号参考功率大于第三门限调整值，低优先级小区用户转移至高优先级小区，使得低优先级小区用户数量减少，高优先级小区用户数量增加，进而使得低优先级小区的负荷减少，高优先级小区的负荷增加，最终两个小区之间的负荷基本达到平衡。For example: in the scenario where the load between the high-priority cell and the low-priority cell is unbalanced and the load of the high-priority cell is smaller than the load of the low-priority cell, when the received signal of the high-priority cell If the power is greater than the third threshold adjustment value, the users in the low-priority cell will be transferred to the high-priority cell, so that the number of users in the low-priority cell will decrease and the number of users in the high-priority cell will increase. The load increases, and finally the load between the two cells is basically balanced.
需要说明的是，当高优先级小区与低优先级小区之间的负荷不均衡时，无论两者之间的负荷大小情况如何，当用户判断出接收信号参考功率处于第一门限值和第二门限值之间，或者接收信号参考功率处于第三门限值和第四门限值之间，均不做任何转移，依然停留在当前的驻留小区，不做小区切换。It should be noted that when the load between the high-priority cell and the low-priority cell is unbalanced, no matter what the load between the two is, when the user determines that the received signal reference power is between the first threshold and the second Between the two thresholds, or when the received signal reference power is between the third threshold and the fourth threshold, no transfer is performed, and the cell remains in the current resident cell without cell handover.
如上，当用户根据基站下发的门限调整值自动进行负荷均衡后，间隔时间T1后，重新取数，返回步骤202，检测负荷均衡效果，即判断高优先级小区和低优先级小区之间的负荷是否已均衡。其中，重新取数是指从小区数据参数库中重新获取小区数据和更新后的门限值，该门限值也即门限调整值。时间T1的取值可根据实际需求设置，例如：可以为5分钟，10分钟或20分钟、30分钟等。As above, after the user automatically performs load balancing according to the threshold adjustment value issued by the base station, after an interval of T1 , the user will re-take the number and return to step 202 to detect the load balancing effect, that is, to judge the difference between the high-priority cell and the low-priority cell Whether the load is balanced. Wherein, re-fetching refers to reacquiring the cell data and the updated threshold value from the cell data parameter database, and the threshold value is also the threshold adjustment value. The value of timeT1 can be set according to actual needs, for example, it can be 5 minutes, 10 minutes or 20 minutes, 30 minutes, etc.
步骤210，检测的负荷均衡结果为均衡，则重置计时器T，进入步骤211。In step 210, the detected load balancing result is balanced, then the timer T is reset, and step 211 is entered.
具体地，本实施例中，当检测到高优先级小区和低优先级小区之间的负荷达到均衡时，重置计时器T，进入步骤211。计时器T的取值可根据实际需求设置，例如：一天至3天。Specifically, in this embodiment, when it is detected that the load between the high-priority cell and the low-priority cell reaches balance, the timer T is reset, and step 211 is entered. The value of the timer T can be set according to actual needs, for example: one day to three days.
步骤211，计时器T倒计时结束，重新取数并判断扇区的负荷是否均衡，若负荷均衡，则重置计时器T，否则，负荷不均衡，返回步骤201。In step 211, the countdown of the timer T is over, and the count is re-taken to determine whether the load of the sector is balanced. If the load is balanced, the timer T is reset; otherwise, the load is unbalanced, and the process returns to step 201.
具体地，本实施例中，当复核扇区的同覆盖异频小区之间的负荷达到均衡时，重置计时器T，否则，从步骤201开始，重新对同覆盖异频小区之间的负荷进行调整使得扇区负荷达到均衡。Specifically, in this embodiment, when the load among the same-coverage and different-frequency cells of the rechecking sector reaches balance, reset the timer T; Make adjustments to balance sector load.

In particular, since two thresholds are set Adjustment value (that is, the first threshold adjustment value and the second threshold adjustment value; or the third threshold adjustment value and the fourth threshold adjustment value), users within the threshold adjustment value range do not perform cell handover, which can effectively avoid receiving signal reference Users whose power is near the threshold frequently switch between different-frequency cells, which improves user experience. In addition, by setting a timer, labor costs can be saved and the time for problem handling can be shortened.
图4为本发明实施例三提供的多载波负荷均衡方法的信令流程图，如图4所示，本实施例提供的多载波负荷均衡方法包括以下步骤。FIG. 4 is a signaling flowchart of a multi-carrier load balancing method provided in Embodiment 3 of the present invention. As shown in FIG. 4 , the multi-carrier load balancing method provided in this embodiment includes the following steps.
步骤301，核心网计算门限调整值，确定门限调整值满足扇区负荷调整条件。In step 301, the core network calculates a threshold adjustment value, and determines that the threshold adjustment value satisfies the sector load adjustment condition.
具体地，本实施例中，核心网根据小区数据参数库中的小区数据和参数计算初始门限值，配置第二初始门限调整步长，并根据初始门限值和第二初始门限调整步长计算门限调整值。然后，确定门限调整值满足扇区负荷调整条件。Specifically, in this embodiment, the core network calculates the initial threshold value according to the cell data and parameters in the cell data parameter database, configures the second initial threshold adjustment step size, and adjusts the step size according to the initial threshold value and the second initial threshold value Calculate the threshold adjustment value. Then, it is determined that the threshold adjustment value satisfies the sector load adjustment condition.
步骤302，核心网下发参数调整指令。Step 302, the core network issues a parameter adjustment instruction.
具体地，本实施例中，当门限调整值满足扇区负荷调整条件，即门限调整值不大于扇区用户平均信号强度时，核心网向各基站发送步骤301中计算得出的门限调整值。Specifically, in this embodiment, when the threshold adjustment value satisfies the sector load adjustment condition, that is, the threshold adjustment value is not greater than the sector user average signal strength, the core network sends the threshold adjustment value calculated in step 301 to each base station.
步骤303，基站更新基站配置参数，参数包括门限初始值。Step 303, the base station updates the configuration parameters of the base station, and the parameters include the initial value of the threshold.
具体地，本实施例中，基站更新其配置参数，该参数包括门限初始值，即将门限初始值更新为门限调整值。Specifically, in this embodiment, the base station updates its configuration parameters, where the parameters include an initial threshold value, that is, the initial threshold value is updated to a threshold adjustment value.
步骤304，小区用户发送参数获取请求。Step 304, the cell user sends a parameter acquisition request.
具体地，本实施例中，小区用户定期向基站发送参数获取请求。Specifically, in this embodiment, the cell user periodically sends a parameter acquisition request to the base station.
该参数获取请求中包括获取参数的标识信息，该参数的标识信息为基站配置参数中的门限调整值的标识信息。The parameter acquisition request includes the identification information of the acquired parameter, and the identification information of the parameter is the identification information of the threshold adjustment value in the configuration parameters of the base station.
步骤305，基站下发参数获取响应。Step 305, the base station sends a parameter acquisition response.
具体地，本实施例中，基站根据小区用户发送的参数获取请求，返回参数获取响应，在参数获取响应中包括相应的参数信息，即门限调整值。Specifically, in this embodiment, the base station returns a parameter acquisition response according to the parameter acquisition request sent by the cell user, and the parameter acquisition response includes corresponding parameter information, that is, a threshold adjustment value.
步骤306，小区用户根据相应参数判断是否进行小区切换。Step 306, the cell user judges whether to perform cell handover according to corresponding parameters.
具体地，本实施例中，小区用户根据门限调整值和小区的接收信号参考功率判断是否需要进行小区切换。用户在选择小区进行切换接入时，会根据当前驻留小区的接收信号参考功率或者与驻留小区相邻的至少一个目标小区的接收信号参考功率与门限调整值进行比较，满足切换条件时即发生小区切换，用户的接入小区由当前的驻留小区改变为目标小区。具体切换过程可参考实施例二中步骤209的描述，此处不再赘述。Specifically, in this embodiment, the cell user judges whether to perform cell handover according to the threshold adjustment value and the received signal reference power of the cell. When the user selects a cell for handover access, the user will compare the received signal reference power of the current cell or the received signal reference power of at least one target cell adjacent to the cell with the threshold adjustment value. A cell handover occurs, and the user's access cell is changed from the current cell to the target cell. For the specific handover process, reference may be made to the description of step 209 in Embodiment 2, which will not be repeated here.

The adjustment of the limit value makes it possible to automatically realize load balancing between different cells in the same sector using equipment from different manufacturers, which improves the utilization rate of network resources. In particular, since two threshold adjustment values (i.e. the first threshold adjustment value and the second threshold adjustment value; or the third threshold adjustment value and the fourth threshold adjustment value), users within the threshold adjustment value range do not perform cell handover, which can effectively prevent users whose received signal reference power is near the threshold value from Frequent switching between different frequency cells improves user experience. In addition, by setting a timer, labor costs can be saved and the time for problem handling can be shortened.
