Question

In LTE/Volte Network one HSS can be share in both or required individual HSS?

Answer 1

3GPP specification depicts many different interfaces such as S6a, Sh between different network nodes and HSS. This is a logical separation of nodes. It is up to vendors and operators requirements how they want to manage their HSS components.
If their hardware resources are sufficient and can serve all the interfaces in a single node then operator would be go through this way. If existing hardware is not enough to handle million of sessions through different interfaces at HSS then either operator would ask vendor to split the HSS or it'll go to buy new hardware.

Answer 2

Hi Shyam,
One HSS can be suffice the requirement for both the technology LTE as well as VOLTE.
There is no need for separate HSS.
