Consideration is given to how to access specified IMS-based services (see clause 22.4 of TS 22.101 9) whilst still allowing other, bespoke services to be offered by the home operator. IMS control of services related to those defined in clause 22.4 of TS 22.101 9 are part of the present scope of this specification.
