LTE (Long Term Evolution) or 3G Long Term Evolution is the evolution of mobile cellular communications technology towards a full edge to edge broadband ip network, and is introduced in 3rd Generation Partnership Project (3GPP) Release 8.

The aim of this 3GPP project is to further develop the Universal Mobile Telecommunications System (UMTS) standard and provide an enhanced user experience and simplified technology for next generation mobile broadband. Scientists and design engineers from more than 60 operators, vendors and research institutes have teamed up to realise this radio access standardization effort.

Much of the 3GPP Release 8 standard will be oriented towards upgrading UMTS to 4G mobile communications technology, and an all-IP flat architecture system.

LTE SON on Self-Configuration

Self-Configuration

Self-configuration is the process that is executed automatically after the physical installation of the
eNB.

An IP address is allocated to the new eNB.

The eNB connects to the OAM system for authentication, software download and configuration data download. The initial radio configuration and transport parameters configuration are completed, and the software is downloaded into the eNB.

The eNB connects to the OAM system for configuration data or normal network management.

The S1-links and X2-links are established and dependent nodes such as MMEs and eNBs are updated with new configuration data.

The inventory system in the OAM is informed that a new eNB is ready to perform the next required operation.
