The present document analyses the scenarios where permanent subscription data that are shared by multiple subscribers
(e.g. MTC UEs) are modified by administration means in the HSS. Existing mechanisms in 3GPP networks to convey
the change of subscription data to relevant MMEs/SGSNs and their drawbacks are outlined and possible solutions
avoiding such drawbacks are discussed.
The recommendation of the document is used to decide whether it is required to standardize any solution, and which is
the final preferred solution if further standardization is needed.
