This TS gives an overall view of how this service shall operate both in the PLMN and within the Mobile Station. This TS defines functionality and is not intended to constrain implementation.
Here is a short description of the MSP service:
Multiple Subscriber Profile is an optional service to enable mobile subscribers to have several profiles associated with a single SIM and a single IMSI, with each profile being a subscription option. Each profile may be used for mobile originated and mobile terminated calls.
Up to four different profiles can be provisioned against a subscriber using the MSP feature. This will allow the subscriber to separate her telecommunication service needs into different identities (e.g. business and home).
The charges accrued for services shall be associated with the appropriate profile, allowing separate charging for each profile.
A supporting visited network shall indicate (on the billing record) for charging purposes the profile used.
