What is LTE interface?

Within an LTE network, LTE Interfaces connect the various components to or within the core . Interfaces allow the MME, SGW and PGW to cooperate with other network elements (e.g. HSS or PCRF). Each one of them is built in a standard way described by 3GPP.org.

GSM – Architecture

The GSM architecture consists of three major interconnected subsystems that interact with themselves and with users through certain network interface . The subsystems are Base Station Subsystem (BSS), Network Switching Subsystem (NSS) and Operational Support Subsystem (OSS).

2G GSM uses defined standard interfaces to connect the network entities to enable interoperability for equipment different manufacturers . GSM primer includes: GSM introduction Network architecture Network interfaces RF interface / slot & burst GSM frames Power classes & control Channels Audio codecs / vocoders Handover.
