As such there are a number of nodes in lte network. The whole network is divided into AS and NAS network.
AS stands for "access stratum", mainly eNodeB belongs to AS network. UE and eNodeB both have air interface (namely Uu interface). Other network is core network which is known as "NAS component" of a network.

MME, HSS, SGW, PGW, PCEF, PCRF, SPR and AF are the main nodes in core network which do their specific task while handling of Ue attach procedure. Every node is the network performs a number of functionality which can't be covered here as one answer. If you want to get more details per node then you have to go through a number of 3GPP specifications .

Hi All,

I want to know, various types of Attach Request for Phone and Wifi devices and what will be the respective attach Accept response from the network in successful Case. I am looking for Network response both in case if network supports VoLTE (Like RJIO)and if network doesnot supports volte (Airtel)....

Does anyone have experience with or awareness of the use of NoSQL databases for 4G LTE EPC network elements such as the HSS or PCRF? These network elements might deal with huge amounts of subscriber data (depending on the subscriber base). These days, the use of NoSQL databases are common among the Internet companies. However, being a relatively newer technology underlining a paradigm shift, as compared to RDBMS, there might not be a large number of instances of the use of NoSQL technology in the Telecommunications industry.

I am looking for feedback on this aspect, and if NoSQL technology is being used, which kind of store (out of Key-Value, Document-based, Column-based, Graph-based) is being used, especially for such elements as HSS or PCRF.

Thank you!
