The architecture of\u00a0LTE<\/a>\u00a0networks is given the technical term System Architecture Evolution or the corresponding abbreviations SAE.<\/p>\n

\u00a0<\/ins><\/p>\n

It is compared to previous wireless networks and provides a simpler structure to process with greater amounts of data. Thereby it provides a faster response time of the entire network.\u00a0The new architecture is also the seamless mobility between\u00a0LTE<\/span> and other wireless technologies such as GPRS or WiMAX.\u00a0Finally, the new architecture could transform the wireless network to an all-IP network.\u00a0This means the data packets are sent to the wireless network in the Internet-standard.\u00a0In order for mobile devices, IP-based services such as IPTV, online games, or data transfer from the Internet, but also Internet telephony is optimized.<\/p>\n

EUTRAN: The wireless network<\/strong><\/p>\n

As with any wireless network even in the LTE, radio network consists of individual cells.\u00a0The device of the user need the radio signals from the base station, from there to the base station – in LTE it is called eNodeB<\/strong>.\u00a0Transmission tower and base station form a cell.<\/p>\n

In LTE radio network, several adjacent radio cells are combined to form a group, which are known as the Tracking Area.\u00a0The entire radio part, that all radio cells and tracking areas of an operator is taken together, the technical English with E\u00a0–<\/strong>\u00a0UTRAN or\u00a0EUTRAN<\/span>\u00a0called.\u00a0The term EUTRAN is from the initials of Evolved Universal Terrestrial Radio Access Network\u00a0formed.\u00a0This part of the network is also referred to as air interface.<\/p>\n

\n

EPC: The core network<\/strong><\/p>\n

The user’s data are going to the\u00a0core network Of the air interface for LTE, which in technical English Evolved Packet Core (\u00a0EPC<\/span>\u00a0is called).\u00a0The Evolved Packet Core consists of three components:<\/p>\n

\n

The first is the MME<\/strong>.\u00a0This abbreviation stands for Mobility Management Entity.\u00a0An MME manages multiple tracking areas.\u00a0The MME is the most important control element in the EPC; it is only responsible for control signals.\u00a0The MME is responsible for the mobility management, which means that they registered and be identified by the exact location of the user, which is a terminal in the LTE network.\u00a0In the MME, it\u2019s possible to notify the user to speak with his terminal.<\/p>\n

The MME also organizes the recognition of the user, or finds his admission.\u00a0Detection of the user accesses the MME to a database, in which the participants are recorded, this means in English technical HSS (Home Scriber server).\u00a0His profile is stored in the MME.\u00a0the MME sets the key, after the data is encrypted and sends it to the base station – or the eNodeB – which performs the encryption.\u00a0When the terminal is turned on, the MME calls him an SGW.<\/p>\n

This SGW<\/strong> (short for English Service Gateway<\/em>) is the second component of an LTE network.\u00a0The service gateway remains the focal point for the user’s device when it switches between two LTE transmission towers or when the LTE network must switch to UMTS or GSM network.\u00a0The SGW is a switching station – it switches the users coming from or addressed to him data to the correct address.<\/p>\n

By the user sent or addressed to him, data runs over the third component: the Public Data Network Gateway<\/strong> (symbol: PGW, meant: Interface for public data networks).\u00a0The PGW is as it were a terminal, where the user’s data from the network of the mobile operator forwarded to other networks or in the data arriving from other networks for him, ready to collect.<\/p>\n

The terminal of a user is able to communicate with a plurality of PDN-GW – if it is responsive simultaneously different networks.\u00a0The PDN gateway also sends data to a computing unit, which is outside of the core network, the PCRF (Policy and Charging Rules Function).<\/p>\n

The user directory and the accounting office<\/strong><\/p>\n

This brings us to the two parts of which are outside of the core network, however, associated with this are: the Home Server Scriber, short HSS are the user data, including a profile stored.\u00a0He is like a complete list of all customers of a mobile operator.\u00a0Here, for example, the identification number (IMSI) of the mobile subscriber is stored or which services are allowed for him.\u00a0There will also be stored at which the MME device was last logged.<\/p>\n

The accounting and control station is finally in the part that policy and charging rules function (PCRF) is called.\u00a0It\u2019s noted that the types of data that arrive in the PGW can be used by the customer, and if so, under which tariff they fall.\u00a0Using this information the bill then finally can create.<\/p>\n","protected":false},"excerpt":{"rendered":"
