Gsm Network Architecture Diagram

The gsm contains most of the necessary capabilities to support packet transmission over gsm.

Gsm network architecture diagram. The 3g umts core network architecture is a migration of that used for gsm with further elements overlaid to enable the additional functionality demanded by umts. From this it can be seen that it is very similar to the more basic gsm network architecture but with additional elements. The subsystems are base station subsystem bss network switching subsystem nss and operational support subsystem oss. The critical part in the gprs network is the mobile to gsn ms sgsn link which includes the ms bts bts bsc bsc sgsn and the sgsn ggsn link fig 1 shows block diagram of gsm architecture.

The ms and the bss communicate across the um interface. The gsm architecture consists of three major interconnected subsystems that interact with themselves and with users through certain network interface. It is the mobile phone which consists of the transceiver the display and the processor and is controlled by a sim card operating over the network. Within this diagram the different network areas can be seen they are grouped into the four areas that provide different functionality but all operate to enable reliable mobile communications to be achieved.

The network architecture for gsm edge was basically the same as that used with gprs sgsn network entity. It is also known as the air interface or the radio link. It consists of the base transceiver station which contains. It acts as an interface between the mobile station and the network subsystem.

This data network overlaps a second generation gsm network providing packet data transport at the rates from 9 6 to 171 kbps. A simplified view of the gsm edge network architecture can be seen in the diagram below. In a gsm network the following areas are defined. Simplified gsm network architecture diagram.

The pcu added to the base station network routed the data according to whether it was packet or circuit switched. From the diagram given above it can be seen that the gprs network architecture added some extra elements to the gsm network to enable it to cary the packet data. A gsm network consists of the following components. Along with the packet data transport the gsm network accommodates multiple users to share the same air interface resources concurrently.

Following is the gprs architecture diagram. The following diagram shows the gsm network along with the added elements. In view of the different ways in which data may be carried the umts core network may be split into two different areas.
