VK,
Its unfortunate I haven’t worked with Ericsson equipment before so I’m not of much use in this respect. However, I think the Ericsson support guys must be able to shed some light. If they don’t have any tool at least they should be able to help you extract the table that stores subscribers’ dynamic data. I’m sure if you get that table the rest you can sort out. Try and talk to your support guys. Alternatively, they can provide you with a spec to interface with their HLR – with a command list their HLR understands – well, at least that’s what the Huawei guys did for us – after requesting of course! 🙂 Good Luck!
