Section: 13.4A Wildcarded Public User Identity
Content: Public User Identities may be stored in the HSS as Wildcarded Public User Identities. A Wildcarded Public User Identity represents a collection of Public User Identities that share the same service profile and are included in the same implicit registration set. Wildcarded Public User Identities enable optimisation of the operation and maintenance of the nodes for the case in which a large amount of users are registered together and handled in the same way by the network. The format of a Wildcarded Public User Identity is the same as for the Wildcarded PSI described in clause 13.5.
