CCNA Training – VoLTE – Voiceover Long Term Evolution
LTE, the future of wireless technology, also known as 4G, has already gained popularity in the wireless world. Service providers are extending their networks that will be functional with LTE. The planning phase of these networks is over and now even the deployment has reached full capacity. LTE will mark a new era in high-speed mobile data delivery, but what researchers are trying to do is use it to transfer voice over IP technology. The process of transferring voice over LTE can be complex, but it will become normal once service providers start playing with it. Although the IP multimedia subsystem will lose its charm, providers are striving to use the same methods as the GSMA for VoLTE delivery. This process would mean that a provider would need to be working at both ends; example IMS and LTE. In fact, this might not be the possible case.
What is more interesting is the use of IMS for VoLTE delivery. This process could end the era of circuit-switched infrastructure. But on the other hand, it could also be a more efficient way to deliver voice data than previous 2G and 3G networks. This process is also cost effective and therefore the implementation will be beneficial. With the implementation of IMS, the Rich Communications Suite services will also play an important role. Presence indications, file transfers, rich messaging, video communication, and address book are some of the services provided by RCS. The revenue generated will not be enough to guarantee the implementation of IMS networks, but it will certainly motivate service providers to use IMS for voice transmission.
If the implementation of the LTE network is done without the IMS, this would end up in a difficult situation to deliver voice, since that would mean that the system would depend on circuit switching; delay voice calls. Latency time is another issue with 6 seconds call setup time. As every problem has a solution, so does the problem of IMS and LTE. The use of VoLGA ensures that calls are made over the LTE wireless link without the use of the IMS infrastructure. But this technology implementation is only practiced by Nokia Siemens Networks with its technology known as Fast track VoLTE; allowing voice to travel over LTE without the IMS. Other providers are still trying their luck with this technology.
