HLR Framework Development for Continuous Integration

Home Location Register (HLR) and Home Subscriber Server (HSS) are the master databases which manages Second Generation (2G), Third Generation (3G) and Fourth Generation (4G) networks. The Continuous Integration (CI) process requires engineers to integrate application features into a single repository frequently. In this paper, an automated HLR framework development for testing the 2G, 3G, 4G or LTE and IMS application features is presented. The HLR framework helps to install and configure the HLR test machines. This framework helps to automate the configuration management on the test machines using Jenkins server to run Sanity and Regression. The HLR Framework Development for Continuous Integration is going to reduce the manual efforts by automating the task of Continuous Integration process such as installation, configuration, execution and generation of a report.

PERFORMANCE ANALYSIS OF STATIC RA GROUPING TO REDUCE THE LOCATION TRAFFIC IN WIRELESS NETWORKS

The terminal's Registration Area (RA) crossing within the Local Signaling Transfer Point (LSTP) area does not generate the traffic to the Home Location Register (HLR). The RAs in LSTP area are grouped statically. It is to remove the signaling overhead and to mitigate the Regional STP (RSTP) bottleneck which may occur in dynamic grouping method. Grouping RAs statically, I lessen the Inconsistency Ratio (ICR) when the caching method is applied to call tracking. The proposed scheme solves the HLR bottleneck due to the terminal's frequent RA crossings and removes the trade-off between call tracking cost and location registration cost to each of the LSTP area.
