Embodiment 1

[0036] In the NSA networking scenario, limited by the frequency range that NSA terminals can support, or other special factors, it is difficult to use all existing LTE base stations as NSA anchor stations. Once an NSA user accesses a non-anchor LTE base station, it will not be possible to add an NR secondary carrier, thus making it impossible to enjoy 5G services. The core network connected to the Option 3X base station is the 4G core network, the control plane is anchored at the 4G base station, and the data distribution control point is placed on the 5G base station. Since the anchor station is used as the signaling channel for the NSA terminal to access the network, the 4G frequency point with good continuous network coverage performance should be selected as the anchor point. In order to select a suitable NSA anchor point, it is necessary to combine the end-to-end support of the anchor point industry chain and the estimated 4G network coverage, and select a 4G frequency po...

Embodiment 2

[0088] In some specific implementation manners, the evaluation system model provided in this embodiment can be used to implement the method for evaluating the quality of anchor stations under the 5G NSA network provided in Embodiment 1.

[0089] The evaluation system model evaluation used in this embodiment mainly uses evaluation factors such as terminal, coverage, capacity, interference, and performance to perform perceptual evaluation of anchor station quality in the dimension of network service quality.

[0090] According to step 102, the evaluation factors for evaluation are selected, and the evaluation principle of each evaluation factor is as follows:

[0091] Terminal Capability: Obtained through DPI. NSA terminals do not necessarily support all LTE frequencies on the live network. Therefore, it is necessary to select mainstream NSA terminal capability information when planning NSA anchor points.

[0092] Coverage level: Obtained through wireless network management da...

Embodiment 3

[0123] In some specific implementation manners, another evaluation system model provided in this embodiment can be used to implement the method for evaluating the quality of anchor stations under the 5G NSA network provided in Embodiment 1.

[0124] The evaluation system model used in this embodiment mainly starts from the three aspects of occupancy, residency, and experience, uses four evaluation factors of terminal, network, pipeline, and business to perform perception evaluation, and anchors the dimensions of network service quality and network service perception. A comprehensive perceptual assessment of website quality.

[0125] According to step 102, the evaluation factors for evaluation are selected, and the evaluation principle of each evaluation factor is as follows:

[0126] Terminals: the number of 5G NSA terminals under the anchor station, the status of the terminal function switch, etc. attached to the anchor station.

[0127] Network: Analyze network quality base...

Abstract

The invention relates to the field of communication, in particular to an anchor station quality evaluation method and device under a 5G NSA network. The method mainly comprises the following steps: acquiring anchor station quality index data; according to the evaluation dimension, selecting an evaluation factor needing to be evaluated from the quality index data; configuring different weights forthe evaluation factors according to evaluation service requirements; and according to the values and the weights of the evaluation factors, calculating a weighted total score of each evaluation factorof the preset evaluation area, and taking the weighted total score as a quality score of the preset evaluation area. According to the invention, the quality condition of each anchor station can be conveniently and accurately obtained, support is provided for 5G NSA network optimization, and the user perception of 5G service users is improved.

Description

【Technical field】 [0001] The present invention relates to the communication field, in particular to a method and device for evaluating the quality of an anchor station under a 5G NSA network. 【Background technique】 [0002] The 5G standard is divided into two networking modes: Non-stand alone (abbreviated as NSA) and standalone (abbreviated as SA). Choose the NSA architecture in the early stage, and then evolve to the SA architecture in the later stage. In the NSA architecture, the anchor station is the channel for the 5G base station to access the network, and the continuous coverage performance of the anchor network affects the user's mobility experience on the 5G network. Especially for 5G voice, it is implemented through VoLTE and uses anchor bearer. If the continuous coverage performance of the anchor point is poor, the voice experience of 5G users may be inferior to that of VoLTE on the existing network, affecting user experience. [0003] At present, commonly used ...
