Embodiment 1

[0111] Embodiment 1. The radius of the coverage area of ​​the cell is used as the specific calculation basis for the cell topology factor.

[0112] For example a i = c i ×r i , where the calculation is based on n i = r i , r i for cell C i (i=0, 1...K) coverage area radius, K is a positive integer; c i is a preset coefficient, which can be determined according to needs, for example, different values ​​can be taken according to different values ​​of i, or a unified value can be taken.

Embodiment 2

[0113] Embodiment 2: The area within the coverage area of ​​the cell whose channel quality is higher than a certain threshold is used as the specific calculation basis for the topology factor of the cell.

[0114] For example a i = n i = Σ j RSRP i , j Σ j RSRP i , j

[0115] Among them, the reference signal received power (RSRP i，j ) or Reference Signal Received Quality (RSRQ i，j ) is cell C i (i=0...

Embodiment 3

[0116] Embodiment 3: The average distance between a cell and surrounding cells is used as a specific calculation basis for the topology factor.

[0117] For example a i = c i ×n i , Among them, l 0，i is the cell C to be judged i (i=0, 1...K) and this cell C 0 The distance between, J is the number of cells to be judged, c i is a preset multiplier factor, determined according to needs, for example, different values ​​can be taken according to different values ​​of i, or a unified value can be taken.

[0118] Step 404, determine the cell C to be judged i Topological dataset T 0，i ;

[0119] Community to be judged C i Topological dataset T of (i=1...K) 0，i Can be expressed in the following form:

[0120] T 0，i ={β 0，i , a 0 , a i , α 0 , α i}, such as error! Reference source not found. Shown: β 0，i is the cell C to be judged i Relative to this cell C 0 The azimuth angle of the cell to be judged is C i The base station where it is located and the cell C 0 ...

Abstract

The invention discloses a method for determining cell adjacent relation. The method includes: obtaining information of a cell and a cell to be judged; determining distance factor of the cell to be judged according to the information the cell and the cell to be judged; determining topology strength factor of the cell to be judged according to the information the cell and the cell to be judged; determining adjacent relation factor of the cell to be judged according to the distance factor and the topology strength factor; and determining adjacent relation of the cell to be judged and the cell according to the adjacent relation factor. The method and a device can determine the adjacent relation between the cells accurately.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and a device for determining the adjacency relationship of a cell. Background technique [0002] With the maturity of the Long Term Evolution (LTE) serial protocols, its commercialization process is also advancing continuously, and terminal manufacturers have also launched various terminals based on the LTE protocols. In the process of commercialization, network planning for the LTE system is urgently needed. [0003] Network planning is a very important task before network construction. Its goal is to plan a wireless network with the largest capacity and coverage as possible at a certain cost and on the premise of satisfying the service quality of the communication network, and to adapt to Future network development and capacity protection requirements. [0004] The access network of the LTE system adopts a cellular network structure, such as figure 1 ...
