Network Organization and Evolution of Signaling Network in LTE Era

Used in LTE network all IP network architecture, compared with 2G / 3G era to TDM network organization is completely different, LTE network between each element communication, 2G / 3G and LTE networks, fixed telephone network exchange to realize. Signaling from the developing trend, diameter protocol will replace traditional SS7 protocol, become widely used in LTE network core network communication protocol, signaling network in the future development trend of IP, diameter signaling network long-term and SS7 signaling network coexist.
