SDM is a database. It consists of following main features.
A typical HLR profile will include below fields:
- HLR (Home Location Register): HLR is a static database.
- AUC (Authentication Centre): Authenticate a subscriber into the network.
- EIR (Equipment Identity register): An EIR reduces the threats of theft of handsets by enabling individual operators to prevent the use of stolen handsets in their own networks. This improves users' security by switching off stolen phones, making them useless for mobile phone thieves and thus less likely to be stolen in the first place
- MNP (Mobile Number Portability): MNP enables mobile telephone users to retain their mobile telephone numbers when changing from one mobile network operator to another.
Services that can be configured using a HLR
- PRBT (Phone Ring Back Tone)
- CAMEL (Customized Applications for Mobile Enhanced Logic): Can set triggers when a call is originated (CCSI) or when a location changes (MCSI)
- ODB (Operator Determined Barring) : i.e. suspend a post-paid customer
A typical HLR profile will include below fields:

Hello there! I came across your blog post on "SDM - Subscriber Data Management: HLR, HSS, and One HLR Concept" and found it very informative. Your article provides a detailed explanation of the various components of SDM and how they work together to manage subscriber data. It's fascinating to learn about the evolution of SDM and how it has become an essential component of modern telecommunications systems.
ReplyDeleteYour discussion of the Home Location Register (HLR) and the Home Subscriber Server (HSS) was particularly interesting. It's impressive how these components manage subscriber data and enable smooth communication between different networks. I also appreciated the way you explained the concept of One HLR, which simplifies the management of subscriber data and enables operators to offer more personalized services to their customers.
Overall, your article provides a great overview of SDM and its various components. I would recommend it to anyone who wants to learn more about the behind-the-scenes workings of telecommunications systems. Thank you for sharing your knowledge and insights!
