A PS Core Network is an Internet Service Provider (ISP)-like in mobile communication we have today. It consists of two

provides connections to mobile phone/equipment to services like the Internet, VOIP, E-mail/Multimedia (SMS/MMS),
Billing, Network Management, and other customized IP Based services. The PS Core Network comprises of the following
Network Elements and Devices; For Radio part: MME/SGSN, Node-B, DNS, L2/L3 Switching/Routing Devices and Fiber
Transmission facilities for physical interfaces between MME/SGSN and Node-Bs. And the Bearer part: Serving

my works. I can stand longer to work on problems finding immediate solution or workaround. Able to work calmly on
under pressure situations. I can work with less to no supervision, but team effort goals and achievements always gives me
excitements and inspiration.
