VoLTE cell capacity estimation using AMR‐WB codecs and considering VAF, SID, packet bundling, and TTI bundling

Abstract: SummaryThe Voice over Long‐Term Evolution (VoLTE) cell capacity notably has an influence on Call Admission Control (CAC) in Long‐Term Evolution (LTE) network. In literature, many techniques have been studied to estimate the LTE cell capacity, but most of them are throughput‐based physical layer (PHY layer) estimate. These estimates do not consider delay requirement, transmission loss, and protocol overhead. In this paper, we have proposed novel analytical models for estimating the VoLTE cell capacity in terms … Show more

“…An estimation of VoLTE capacity per cell has been calculated and considered in [14] and [15], where only data Physical Resources Blocks (PRBs) based analysis is developed, without considering possible limitations due to control channels. 5G capacity calculations have been indirectly introduced in [16], presenting control channel resources and some simplified VoNR capacity calculations while comparing results with VoLTE.…”

“…Each CCE is composed by multiple Resource Element Groups (REGs), in turn made up of groupings of REs, which number vary for LTE and 5G. To simplify the calculations, a relationship between MCS and AL has been determined as a function of whether the radio conditions are optimal (22)(23)(24)(25)(26)(27), average (15)(16)(17)(18)(19)(20)(21), bad (7)(8)(9)(10)(11)(12)(13)(14) or very bad (0-6). The corresponding MCS-AL mapping is defined in [18], as 2 for average conditions, 4 for bad, and 8 for very bad.…”

“…With V2X technology, RSUs can collect information about vehicles on the road network. The mobile edge computing unit can assess the capacity and update the condition of each road segment in real-time ( 19 ). Connected vehicles can receive the updated road network capacity and optimize the navigation information in time so that they can choose a better lane to avoid congested segments of urban roads and travel efficiently.…”
