Embodiment 1

[0042] refer to figure 1 , shows a flowchart of steps of a load balancing method in Embodiment 1 of the present invention. In this embodiment, the load balancing method can be, but is not limited to, applied to a private high-speed rail network covered by a double-layer network. For example, the first cell and the second cell may be two cells on a two-layer network, and the first cell and the second cell are cells with completely the same coverage.

[0043] Wherein, the load balancing method includes:

[0044] Step 102, acquiring a set of users satisfying the handover condition from the first cell to the second cell.

[0045] In this embodiment, the set of users satisfying the handover condition from the first cell to the second cell is acquired, that is, the set of users satisfying the load balancing handover condition is acquired. Wherein, it should be noted that, in this embodiment, in step 102, only a set of users satisfying the load balancing handover condition is dete...

Embodiment 2

[0055] refer to figure 2 , shows a flowchart of steps of a load balancing method in Embodiment 2 of the present invention. In this embodiment, the load balancing method includes:

[0056] Step 202, acquiring a set of users satisfying the handover condition from the first cell to the second cell.

[0057] In this embodiment, the acquisition of the set of users satisfying the handover condition from the first cell to the second cell is to determine the users in the first cell that meet the load balancing handover condition. Wherein, the first cell and the second cell are cells with the same coverage.

[0058] Preferably, a feasible way to obtain a user set may be as follows: according to the physical resource block utilization rate and / or the number of users of the first cell and the second cell, determine the users who meet the handover condition from the first cell to the second cell gather.

[0059] Step 204, when the user in the first cell moves to the edge of the cell,...

Embodiment 3

[0078] In combination with the foregoing embodiments, this embodiment takes load balancing switching in a high-speed rail scene as an example to describe the load balancing method.

[0079] refer to image 3 , which shows a schematic diagram of a high-speed rail private network covered by a two-layer network in Embodiment 3 of the present invention. Such as image 3 , the high-speed rail private network is configured with a two-layer network (a first-layer network and a second-layer network), and adjacent co-frequency adjacent cells. Wherein, the two-layer network can use two frequency points in the same frequency band, assuming that the frequency points of the two-layer network are F1 and F2 respectively. Specifically, Cell1 and Cell3 may be two adjacent adjacent cells of the same frequency, Cell3 is a different-frequency and same-coverage cell of Cell1, and Cell4 is a different-frequency and same-coverage cell of Cell3; the frequency points of the Cell1 and Cell3 are the s...

Abstract

The invention provides a load balancing method and device. The method comprises the steps of acquiring a user set meeting a switching condition of switching from a first cell to a second cell, whereinthe first cell and the second cell are completely identical covered cells; when users in the first cell move to a cell edge, determining switching users; determining whether the switching users matchwith the user set; and if yes, switching the switching users to a fourth cell, wherein the fourth cell is a neighboring cell of the same frequency of the second cell. The existing load balancing method has problems of frequent switching, high switching failure rate, and low user experience. The method solves the problems in the prior art.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a load balancing method and device. Background technique [0002] With the development of mobile communication technology, a single-layer network can no longer fully meet the needs of users. For example, in high-speed high-speed railway scenarios, the traditional single-layer network cannot meet the high-quality experience of high-speed rail mobile users. In order to ensure user experience, in high-speed high-speed rail and other mobile user scenarios, a two-layer network is usually used. [0003] In a two-layer network environment, one of the problems usually faced is load balancing: balance the users in the high-load cell to the low-load cell, so that the load of the two-layer network can be balanced. For example, in a completely same-coverage scenario, users can be balanced to another layer of the same-coverage network through blind handover after the load-balancing co...
