Overview Of The GSM System and Protocol Architecture. The current fourth generation wireless mobile network (4G) based on All-IP Network architecture provides high data rates, low latency and low-cost implementation. But there are few specific user applications that require very high data rate and uninterrupted access to the internet. A sophisticated modern mobile technology termed the, change in LTE network architecture. VoLTE (Voice over LTE) is thus proposed to fulfill this evo-lution [1, 2]. Its design seems quite straightforward. It carries voice traffic in packets over the IP-based LTE network, no longer through an dedicated circuit. To facilitate voice communication, each VoLTE call also maintains a separate signaling.
