| Abstract: | With the continuous development of LTE network, the coverage of D+F multi-layer network is gradually mature. According to the characteristics of VoLTE service, it is carried in a fixed frequency layer to realize LTE voice and data layering. Based on the respective advantages of LTE multi-layer network and the demand of strong coverage and low rate of VoLTE service, this paper separates VoLTE service users into F2 frequency layer to optimize the coverage of VoLTE network and enhance user perception. |
