Background
In an external field dual-carrier and three-carrier networking scene, the difference of the number of RRC (radio resource control) connected users of two cells with the same coverage (namely, the same coverage range) is found to be large, but the PRB utilization rate is not high. The reason for this may be that the number of users accessing one cell in the same coverage cell has reached the maximum number of users accessing the cell, and the users cannot be admitted any more, which results in a large number of RRC connection reject messages and affects KPI indicators. But the number of users in another cell is very small, resulting in uneven resource utilization.
However, in the process of implementing the invention and creation, the inventor finds that the current load balancing strategy for the number of users between stations only balances two cells with the same bandwidth, which is relatively limited and has a complex external field environment. For two inter-station same-coverage adjacent cells with different bandwidths (the two cells have different bandwidths and the same coverage range but belong to different base stations), the user number balancing current algorithm still processes the user balancing number according to the user balancing mode between the cells with the same bandwidth to convert the user balancing number.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
In a first aspect, an embodiment of the present invention provides a method for balancing users in cells with different bandwidths and coverage between stations, where the method is applied to a network side device, and as shown in fig. 1, the method includes:
s101, if a user number balancing switch is turned on and the existence of inter-station same-coverage adjacent cells is judged, sending a resource state request to an adjacent cell, wherein the resource state request is used for indicating the number of connected users of the adjacent cell sent to the cell by the adjacent cell;
specifically, a network side device (e.g., a base station) configures a user number equalization switch FLAG. When the FLAG is turned on, the subsequent user equalization decision or equalization operation is performed. When the FLAG is turned on, if it is determined that the inter-site co-coverage neighboring cell of the local cell currently exists, as shown in fig. 2, the local cell (i.e., the source cell eNB1 in fig. 2) sends a RESOURCE STATUS REQUEST (i.e., the RESOURCE STATUS REQUEST in fig. 2) to the neighboring cell (i.e., the target cell eNB2 in fig. 2). And the base station sets the idle 30-BIT position in the Report Characteristics IE field in the request to be 1, and further indicates the number of the connected users of the adjacent cell reported to the source cell by the adjacent cell. Further, the number of connected users of the neighbor cell can be indicated to the source cell by the neighbor cell periodically.
S102, acquiring the bandwidth of the neighbor cell according to a pre-stored neighbor cell relation table or an external neighbor cell relation table;
specifically, the source cell base station may increase the bandwidth MIB nodes in the neighbor relation table and the external neighbor table in advance, and may manually add the bandwidths of the corresponding neighbors in the two tables. Therefore, the source cell base station can acquire the bandwidth of a target cell (namely, a neighbor cell to be subjected to user equalization) which is the same coverage cell as the source cell in station according to any one of the prestored neighbor cell relation table and the external neighbor cell relation table.
It should be noted that, once the bandwidth of the target cell changes, the target cell base station sends a base station update message to other adjacent base stations, so that the other base stations can timely change the information thereof to enable subsequent base station switching and other operations, and the base station update message carries the bandwidth after the target cell changes. When the source cell base station receives the base station updating message, the source cell base station can modify the pre-stored neighbor cell relation table and the external neighbor cell relation table according to the bandwidth of the target cell carried in the base station updating message after the target cell is changed.
S103, when a first difference value between the number of connected users in the cell and a preset user number balance threshold is determined to be larger than 0, if the bandwidth of the cell is judged to be larger than that of the adjacent cell, whether a first preset condition is met is continuously judged;
the first preset condition includes: the number of first connecting users of the cell is larger than that of the adjacent cell, the ratio of a second difference value between the number of the first connecting users and the number of the adjacent cell connecting users to the number of the first connecting users is larger than or equal to a preset user number difference threshold, and the first ratio value between the second difference value and 2 is larger than or equal to 1; the first connecting user number is the user number obtained by converting the connecting user number of the cell into the bandwidth between the cell and the adjacent cell;
before the detailed description, the symbolic representations of the respective parameters will be described first.
Ns: the number of current connection users in the cell;
nn: the number of current connected users of the target neighbor cell;
BWs: the value of the bandwidth of the cell can be 20M, 15M, 10M and 5M. The values can be taken because the application scenario mainly considered in the embodiment of the present invention includes dual carrier networking with different bandwidths in the 20M \15M \10M \5M bandwidths in a pairwise combination manner. The method includes scenarios such as TDD + FDD (Time Division duplex + Frequency Division duplex) dual-carrier, TDD dual-carrier networking, and the like.
BWn: the adjacent cell bandwidth can be 20M, 15M, 10M and 5M;
lbclusernumdiffernt: a user number difference threshold;
lbcFastHoMaxUserNum: the maximum number of switching users each time;
lbcluser numthreshold: the number of users is equalized to a threshold.
That is, upon determining that Ns is greater than lbclufernumthreshold, it may be determined that user equalization is currently needed. The relationship between the bandwidth BWs of the cell and the bandwidth BWn of the neighbor cell is continuously determined. If BWs is greater than BWn, whether the first preset condition is met is continuously determined. The first preset condition here includes:
(a) the number of first connecting users in the cell is larger than that in the adjacent cell;
the first number of connected users is the number of users obtained by converting the bandwidth between the local cell and the adjacent cell from the number of connected users of the local cell. The specific conversion process can be realized by the following formula: FLOOR (Ns BWn/BWs), FLOOR is a rounded down function.
Thus condition 1, i.e., FLOOR (Ns BWn/BWs) > Nn;
(b) the ratio of the second difference between the number of the first connecting users and the number of the adjacent cell connecting users to the number of the first connecting users is more than or equal to a preset user number difference threshold, namely:
(c) the first ratio of the second difference to 2 is greater than or equal to 1. Namely:
and S104, if the number of the users in the cell is met, taking the minimum value of the maximum switching user number in each time, the first difference value and the first ratio as the number of the users balanced to the adjacent cell in the period.
Specifically, if it is determined that the conditions (a) to (c) are satisfied, the number N of users who are balanced to the neighboring cell in the present cycle is determined0Comprises the following steps:
in the method for processing user balance between inter-station different bandwidths and same coverage cell provided by the embodiment of the invention, the MIB node of the adjacent cell bandwidth is added in the adjacent cell relation table of the base station and the external adjacent cell relation table, so that the bandwidths of the inter-station same coverage adjacent cell can be obtained. And when determining that the user balance is needed and the bandwidth of the cell is larger than that of the adjacent cell, firstly converting the number of users of the cell according to the ratio of the bandwidth of the cell to the bandwidth of the adjacent cell, then performing balance judgment, and finally determining the number of users balanced to the adjacent cell in the period when the judgment meets the balance condition. Compared with the existing user balancing mode, the method provided by the embodiment of the invention can solve the problem of balancing the number of users between the cells with different bandwidths and balance more reasonable number of users.
It can be understood that, in specific implementation, after it is determined that user equalization is required (that is, the number of users connected to the current cell is greater than the user equalization number threshold), a situation that the bandwidth of the current cell is smaller than the bandwidth of the neighboring cell may also occur, so the method provided in the embodiment of the present invention may further include:
s103', if the bandwidth of the cell is judged to be smaller than that of the adjacent cell, whether a second preset condition is met or not is continuously judged;
the second preset condition includes: the number of connected users in the cell is larger than the number of second connected users in the adjacent cell; the ratio of a third difference value between the number of connected users in the cell and the number of second connected users to the number of connected users in the cell is greater than or equal to a preset user number difference threshold, and the second ratio value between the third difference value and 2 is greater than or equal to 1;
specifically, the second preset condition here includes:
(d) the number of users connected in the cell is larger than the number of users connected in the second adjacent cell. The second connection user number is the user number obtained by converting the bandwidth between the cell and the adjacent cell from the connection user number of the adjacent cell; namely:
Ns＞FLOOR(Nn*BWs/BWn) (4)
(e) the ratio of a third difference value between the number of the connected users in the cell and the number of the second connected users to the number of the connected users in the cell is more than or equal to a preset user number difference threshold; namely:
(f) a second ratio of the third difference to 2 is greater than or equal to 1; namely:
and S104', if the number of the users in the cell is met, taking the minimum value of the maximum switching user number of the cell each time, the first difference value and the second ratio as the number of the users balanced to the adjacent cell in the period.
That is, if the above conditions (a) to (c) are satisfied, the number N of users who are balanced to the neighboring cell in the present cycle0Comprises the following steps:
determining the number N of users who are equalized to the adjacent cell0Then, the method provided by the embodiment of the present invention may further include:
s105, after the number of the users balanced to the adjacent cell in the period is determined, N in the cell is determined0Individual user configurations are a4 event load balancing measures;
where eventA4 indicates that the neighbor cell quality is above an absolute threshold. Similar to cell reselection moving to high priority.
Event entry conditions: mn + Ofn + Ocn-Hys > Thresh
Event leaving conditions: mn + Ofn + Ocn + Hys < Thresh
And S106, balancing the configured users to the adjacent cells when the A4 event report is received.
When the quality of the adjacent cell is higher than an absolute threshold, N in the cell is determined0The individual users are equalized into the neighbor cells.
