What Is VoLTE

What Is VoLTE

Success dependant on optimisation and planning in center and RAN. A brand-new service brings traffic patterns, placing requirements. VoLTE is a good example, and making sure it'll work means embracing priorities in the radio access network and center both for preparation and optimisation. Here, Daniel Ramirez of TEOCO summarizes of optimizing a network for VoLTE some principles. Optimising in order in order in order for VoLTE: overcoming the challenges facing operators - Director of RAN Products, By Daniel Ramirez, TEOCO - VoLTE might offer fertile ground. As solutions gain in popularity, it'll place never seen requirements on operators LTE networks and new. 

New kinds of traffic generate patterns of use. The operators community may not have experienced this before, also may not happen to be optimized to handle this shift. Covering - Like any other solutions that are new, the challenges can be different in developing and developed markets. Within markets that are creating, a most of the challenges fall into the kind of covering the principles of optimisation and wireless access system design. VoLTE is an information service, and thus the RAN design has to be optimised to deliver the right quality. 

Nevertheless, whereas a normal information call might be throttled down if the user is in an area of low quality, A VoLTE call has a guaranteed speed of service. Which implies That, if the quality of the community is anything less than average, the requirements of VoLTE calls could grow exponentially and this could result on a couple of users rapidly hogging many of that the capacity available in a cell. To explain how this occurs, we need to understand a metric known as Call Quality Index. This is an indication sent from that the user device to that the network, with CQI 15 represents that the best quality and CQI 1 that the worst. 

When the handset signals low conditions the network responds, however does so differently for information than for VoLTE services. With VoLTE, when a device registers a CQI of 7 or lower, that the community responds by sending a disproportionately large amount of mobile resources to the device, in the shape of Physical Resource Blocks, hogging capacity. This causes that the overall quality of that the community to decrease. This places specific pressure on LTE networks only, because, without that the luxury of a 3G community to fall back on, demand from VoLTE calls creates an enormous capacity issue. The continued growth of this problem, from that the moment that the network falls to below average, is something which must be kept in the forefront by operators when deploying VoLTE solutions in creating markets.
