Consistent with its track record, Tecore is leading the industry by delivering an Evolved Packet Core (EPC) focusing specifically on the needs of smaller markets. The Evolved Packet Core (EPC) is a new, end-to-end packet core architecture for 4G Long-Term Evolution (LTE) that provides a converged voice and data networking framework to connect users to an LTE network. Author: Frédéric Firmin, 3GPP MCC. This article looks at the Evolved Packet Core (EPC), the core network of the LTE system, giving an overview of the.

The key constituents of Evolved Packet Core evolved packet core Mobility Management Entity — Helps in authenticating and tracking users in the network as well as managing session states Serving Gateway — Helps in routing data packets across the network Packet Data Node Gateway — Helps in managing quality of service provided and also in deep packet inspection Policy and Charging Rules Function — Helps in policy enforcement and in supporting service data flow detection Evolved Packet Core helps in integrating networks by combining the different transfer modes such as synchronous transfer mode and asynchronous transfer mode in the existing systems.

The UE evolved packet core the network execute the attach procedure, the default EPS bearer context activation procedure in parallel.

Evolved packet core UE and network complete the combined default EPS bearer context activation procedure and the attach procedure before the dedicated EPS bearer context activation procedure is completed.

The success of the attach procedure is dependent on the success of the default EPS bearer context activation procedure.

  • What is Evolved Packet Core (EPC)? - Definition from Techopedia
  • The Evolved Packet Core

If the attach procedure fails, then the ESM session management procedures also fails. Together with the bearer control provided by the Access Stratumit provides the control of user plane bearers. An EPS bearer context evolved packet core be either a default bearer context or a dedicated bearer context.

Additionally, the network can activate one or several dedicated EPS evolved packet core contexts in parallel. Types of ESM procedures: ESM involves different types of procedures such as: Transaction related procedures — initiated by the UE to request for resources, i.

The main features provided by SCTP are: An association is a connection evolved packet core is set up between two endpoints for data transfer, much like a TCP connection.

A SCTP association can have multiple addresses at each end.

Delivers sequenced data in a stream Elimination of head-of-line blocking: SCTP ensures the sequenced delivery of data with multiple unidirectional streams, without blocking evolved packet core chunks of data in other evolved packet core. The P-GW informs the charging system about pre-paid users payload in real time.

Diameter protocol is used in the Gy interface. These rules contain charging related information as well as Quality of Service QoS parameters that will be used in the bearer establishment.

Diameter evolved packet core is used in the Gx interface. It does not have a circuit-switched domain, which is traditionally used for phone calls and SMS. This feature was developed in Rel There is no inter-system change for sending or receiving SMS.

This feature was specified in Rel These access technologies are composed of:
