SGSN in a 2.5G GPRS Network
SGSN in a 2.5G GPRS Network • SGSN in a 2.5G GPRS Network, on page 1 • 2.5G SGSN Configuration Components, on page 2 • How the 2.5G SGSN Works , on page 4 • Information Required for the 2.5G SGSN, on page 6 SGSN in a 2.5G GPRS Network This chapter outlines the basic configuration and operation of the Serving GPRS Support Node (SGSN) in 2.5G GPRS wireless data networks. The simplest configuration that can be implemented on the system to support SGSN functionality in a 2.5G network requires one context but we recommend a minimum of two: one for the SGSN service (required) and another for the charging context. The service context organizes the following: • GPRS service configuration • MAP (Mobile Application Part) configuration • DNS (Domain Naming System) configuration for resolution of APN (Access Point Name) domain names • SGTP (SGSN GPRS Tunneling Protocol) configuration The charging context facilitates the following: • Configuration of connectivity to the CGF (Charging Gateway Function) The following functionality is configured at the global or system level in the local management context: • NSEI (Network Service Entity Identity) configuration • SCCP (Signalling Connection Control Part) network configuration • SS7 (Signaling System 7) connectivity configuration • GTT (Global Title Translation) configuration To simplify configuration management, more contexts can be created to categorize the service configuration. Each context can be named as needed. The contexts listed above can be configured as illustrated in the figure on the next page. SGSN in a 2.5G GPRS Network 1 SGSN in a 2.5G GPRS Network 2.5G SGSN Configuration Components 2.5G SGSN Configuration Components In order to support 2.5G SGSN functionality, the system must be configured with at least one context for the GPRS service (2.5G SGSN service). -

SS7 Protocol Stack
CHAPTER 3 SS7 Protocol Stack This chapter describes the components of the SS7 protocol stack. A stack is a set of data storage locations that are accessed in a fixed sequence. The SS7 stack is compared against the Open Systems Interconnection (OSI) model for communication between different systems made by different vendors. Figure 3-1 shows the components of the SS7 protocol stack. SS7 Level 1: Physical Connection This is the physical level of connectivity, virtually the same as Layer 1 of the OSI model. SS7 specifies what interfaces will be used, both Bellcore (Telecordia) and ANSI call for either the DS0A or the V.35 interface. Because central offices are already using DS1 and DS3 facilities to link one another, the DS0A interface is readily available in all central offices, and is preferred in the SS7 network. As the demands on the SS7 network increase (local number portability), and as the industry migrates toward ATM networks, the DS1 interface will become the link interface. SS7 Level 2: Data Link The data link level provides the network with sequenced delivery of all SS7 message packets. Like the OSI data link layer, it is only concerned with the transmission of data from one node to the next, not to its final destination in the network. Sequential numbering is used to determine if any messages have been lost during transmission. Each link uses its own message numbering series independent of other links. SS7 uses CRC-16 error checking of data and requests retransmission of lost or corrupted messages. Length indicators allow Level 2 to determine what type of signal unit it is receiving, and how to process it.
