There are certain advantages which VoLTE offers:[br] [br][br]

[br][br][ul][li]1. Packet Switched Voice[br][/li][/ul][br]

[br][br]Unlike 2G and 3G networks, where voice is over circuits, Voice over LTE works on the packet switched network.[br][br]Hence, all the technological advancements around IP QoS and moving forward towards SDN (Software Defined Networking) become a natural fit. Hence, while implementing VoLTE we make sure that VoLTE quality of service classes have a direct mapping with IP DSCP QoS classes.[br][br]2. HD Voice.[br][br] [br]

[br][br][br]Voice over LTE mandates the use of HD Voice codecs such as AMR Wideband. This gives an enhanced voice quality experience which is not available in circuit switched networks.[br]With the evolution of standards, more advanced and adaptive bit rate codecs such as EVS have come into being for VoLTE services.[br][br]3. More Capacity with good quality[br][br]With VoLTE, operators can strike the right balance of providing higher Voice capacities in their RF networks using IP based voice - while still guaranteeing quality of service.[br][br]4. Video Calling[br][br]

[br][br]Voice over LTE also supports native video calling. Video services use the HD video codec called H.264. Hence, there is an opportunity for operators to offer innovative video services on their packet networks.[br][br]5. Faster call setup time.[br][br]When we use Voice over LTE (VoLTE), there are several differences in the way calls are terminated.[br][br]LTE is an always-on technology. What this essentially means is that a dedicated IP session is reserved for each user in the network.[br][br]This IP session is also known as the default EPS bearer which exists between the device and the PGW.[br][br]On similar lines, the device is also registered with the IMS core network and a dedicated IPSEC tunnel is established with the P-CSCF to carry call setup signalling traffic.[br][br]In a nutshell - Voice over LTE ensures an always-on experience through end to end resource reservation in the network for each user.[br][br]Hence, call setup times (latency) is minimal.[br][br]-----------------------------------------------------------------[br]Thanks for reading {:16_24:}[br]if you Like this information share this thread and give your feedback.{:16_1:}[br]-----------------------------------------------------------------
