Embodiment Construction

[0099] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0100] The VoLTE service belongs to the packet domain service, and its capacity directly depends on the spectrum efficiency. As shown in Table 1, due to the mutual constraints and influences of different service quality requirements, wireless resources, network configuration, wireless environment, and feature functions, the LTE The system's support capacity for VoLTE services is not a fixed value, and due to the particularity of the LTE-TDD...

Abstract

The invention discloses a method and device for determining LTE-TDD cell service support capacity. The method comprises the following steps: determining user number capable of supporting a VoLTE service of a PDSCH according to the downlink available RB number, the downlink RB number averagely occupied by each VoLTE service, and a first influence factor; determining the user number capable of supporting the VoLTE service of the PUSCH according to the uplink available RB number, the uplink RB number averagely occupied by each VoLTE service, and a second influence factor; and determining the user number capable of supporting and used for scheduling the VoLTE uplink service of the PDCCH and a user number used for scheduling the VoLTE downlink service according to the RE number in each VoLET service period, the cell average CCE aggregation degree and the third influence factor. The method for determining LTE-TDD cell service support capacity disclosed by the embodiment of the invention have important significance for the whole planning and service development strategy of the network.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for determining the service support capacity of an LTE-TDD (Time Division Long Term Evolution, long-term evolution based on Time Division Duplex) cell. Background technique [0002] VoLTE (Voice over LTE, voice solution carried by LTE) is a voice service based on IMS (IP Multimedia Subsystem, multimedia subsystem), which can realize the unification of data and voice services under the same network. As an emerging voice solution, VoLTE belongs to VoIP (Voice over Internet Protocol) technology. It is carried and realized through LTE (Long Term Evolution, Long Term Evolution) network, and will gradually replace mainstream voice solutions. GSM (Global System for Mobile Communication, Global System for Mobile Communications) and CSFB (Circuit Switched Fallback). Therefore, it is of great significance to accurately evaluate the support capacity...
