IPLOOK 4G/5G Core
Network Virtualized EPC and IMS Core
NB-IoT is one solution of IoT which focuse on connection of things. It one part of the 5th generation of communication system.
① :
Deep Coverage
② :
Massive Connections
③ :
Low Power Consumption
2.1 Deployment strategy
l Compact Deployment
As is shown in the figure 2.3.1.1-2, Compact Deployment integrates almost all the network elements in one IPC(Industrial Personal Computer), including MME, SGW, PGW and HSS. The management and maintenance are much easier than traditional way.
l Virtualized Deployment
As is shown in the figure 2.3.1.2-1, virtualized Deployment takes use of general x86 server as the platform. The function can be NFV element and deployed in the data center. Or, the network elements can be directly deployed on the X86 server to reduce the CAPEX. In Addition, IPLOOK could deployall the network elements into one sever like compact Deployment, and could also deploy every different network elements into different severs, according to custom’s personal needs.
l Standard Carrier Grade Deployment
As is shown in the figure 2.4.1.3-1, Standard Carrier Grade EPC uses the ATCA chassis as the hardware platform. The MME/SGW/PGW/HSS can be stand-alone or integrated in one chassis according to the capacity requirement.
