• P-LTE Convergent Core - eTC3800

    3GPP Standard Evolved Packet Core (EPC)


Convergent, Powerful and Flexible

Evolved Packet Core (EPC) is a framework with high data rate, low latency, and optimized packet mechanism. With improved packet switching technology, EPC addresses the growing demand for IP data traffic.

Born for Convergence

As a LTE-PMR convergent design core, eTC3800 is integrated with professional transmission and operation technology to meet the large mount of various data from each terminal. It supports media applications to enhance system performance and quality of service (QoS).The basic capabilities of EPC include the IP service support, IP session control, and QoS management.

Diverse functions of eTC3800

Identity Management

Supports the allocation and management of the user's identity, as well as the validity check of the user identity.
The user identity includes International Mobile Subscriber Identity (IMSI), Globally Unique Temporary Identifier (GUTI), Mobile Subscriber International ISDN number (MSISDN), International Mobile Equipment Identity (IMEI), Access Point Name (APN), Tracking Area identity (TAI), QoS Class Identifier (QCI) and etc.

Flexible Deployment

EPC supports flexible networking and system design according to user capacity. Adopting standard server or ATCA, EPC meets different capacity requirements of the users. Capacity expansion can be easily achieved by increasing ATCA boards or by ATCA cascading.

Multifaceted Guarantee of Security

Supports two-way AKA authentication between the network and the UE and security key management , and provides encryption and integrity protection for the access layer (AS) and the non-access stratum (NAS).

High Reliability

In terms of hardware, EPC adopts the industry-standard Advanced Telecom Computing Architecture (ATCA). ATCA features modular design, easy extensibility and manageability. It supports dual-star topology BASE and Fabric interfaces, dual redundant power modules, providing carrier-class high reliability.
