Cisco Cisco IOS Software Release 12.2(8)YW

The following new software features are supported by the Cisco 7000 family for Cisco IOS 
Release 12.2(8)YW:

Platforms: Cisco 7200 series routers

GPRS is a service designed for Global System for Mobile Communications (GSM) networks. GSM is a 
digital cellular technology that is used worldwide, predominantly in Europe and Asia. GSM is the 
world’s leading standard in digital wireless communications. 

GPRS is standardized by the European Telecommunications Standards Institute (ETSI). The most 
common application of GPRS is expected to be Internet/intranet access. Cisco Systems’ GPRS solution 
enables mobile wireless service providers to supply their mobile subscribers with packet-based data 
services in GSM networks.

GPRS introduces the following two new major network elements:

SGSN—Sends data to and receives data from mobile stations, and maintains information about the 
location of a mobile station (MS). The SGSN communicates between the MS and the GGSN. SGSN 
support is available from Cisco partners or other vendors.

GGSN—A wireless gateway that allows mobile cell phone users to access the public data network 
(PDN) or specified private IP networks. The GGSN function is implemented on the Cisco Systems’ 
router.

The GGSN R4.0 release provide the combined 2.5G and 3G packet gateway support and interworking 
capability on the same node.

into more scalable MIBs without affecting existing Cisco IOS products or network management system 
(NMS) applications. You can update from deprecated MIBs to the replacement MIBs as shown in
