Embodiment Construction
[0059] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0060] An embodiment of the present invention provides a network structure evaluation method, such as figure 1 shown, including the following steps:
[0061] Step S101, obtain the test information of N sampling points in the serving cell. For any sampling point, the test information includes at least the first level test information of the serving cell at the sampling point, the first level test information of each co-frequency adjacent cell of the serving cell at the sampling point. Two-level test information.
[0062] Step S102: Determine the signal-to-interference ratio of the servi...

The embodiment of the present invention provides a network structure evaluation method and device, including: obtaining the test information of N sampling points in the serving cell, and for any sampling point, the test information includes at least the first level test information of the serving cell at the sampling point . The second level test information of each co-frequency adjacent cell of the serving cell at the sampling point; determine the signal-to-interference ratio of the serving cell according to the first level test information and the second level test information of each sampling point. The network structure of the serving cell is evaluated according to the signal-to-interference ratio of the serving cell. Since the signal interference ratio is determined based on the accurate value of the level test information of the serving cell and adjacent cells at the same frequency at the sampling point, the network structure of the serving cell is more fully characterized, thereby improving the accuracy of network structure evaluation. Secondly, the SNR of the unloaded structure and the SNR of the fully loaded structure are introduced as the evaluation index of the network structure, which brings convenience to the evaluation and optimization of the network structure by wireless network professionals.
Description
technical field [0001] Embodiments of the present invention relate to the field of wireless communication, and in particular, to a network structure evaluation method and device. Background technique [0002] The existing network structure is planned according to the cellular structure, but due to the deviation between actual site selection and planning, a large number of co-frequency signals often overlap and cover each other, causing serious internal system interference. From the measured data results, it can be concluded that the more same-frequency signals in the serving cell, the worse the Signal to Interference plus Noise Ratio (SINR) is, indicating that network structure problems will lead to a decrease in the communication quality of the serving cell. In order to evaluate the impact of the network structure on the serving cell, a method of counting the number of handicaps in the sampling points of the serving cell is used in the prior art. The specific process is as...
