Abstract

The invention provides a network expansion method and a network expansion evaluation device, which relate to the technical field of communications and are applied to cell network expansion. The network expansion method comprises the steps: obtaining a busy-hour RRC (Radio Resource Control)maximum connection number X, busy-hour eNodeB successful response times Y, a busy-hour downlink PRB (Physical Resource Block)utilization rate Mand busy-hour downlink data total throughput N of a to-be-evaluated cell,and average call duration Q of a voice service of an existing network cell; according to the X, Y and Q, calculating to obtain an RRC maximum connection number X' of the to-be-evaluated cell after VoLTE (Voice over LTE)is opened; according to the M, Y, Q and N, calculating to obtain a PRB utilization rate M' of the to-be-evaluated cell after the VoLTE is opened; if the X' is larger than a preset downlink RRC user connection number threshold and the M' is smaller than or equal to a downlink PRB utilization rate threshold, additionally configuring a user connection number for the to-be-evaluated cell; if the M' is larger than the downlink PRB utilization rate threshold, transferring preset parts of services of the to-be-evaluated cell based on FDD LTE(Frequency Division Duplexing Long Time Evolution) network.

Description

Technical field [0001] The invention relates to the field of communication technology, in particular to a network expansion method and a network expansion evaluation device. Background technique [0002] The voice service of the FDD-LTE (Frequency Division Duplexing-Long Term Evolution) network adopts CSFB (Circuit Switched Fallback) to fall back to 3G, that is, users need to fall back to the 3G network for voice calls. After VoLTE (VoiceoverLTE) is opened in the future, voice services and data services can be performed at the same time. As long as users are in a voice call, they will always be in the RRC connection state of the 4G network, which will inevitably bring about a sudden increase in network load. [0003] Existing network expansion standards do not consider the load caused by the addition of voice services to FDDLTE, which may cause overload in some cells and cause congestion, which seriously affects user perception. Summary of the invention [0004] The embodiment of t...
