MobileTerminatedCall

Validations ASN.1 Parent Types

A Mobile Terminated Call item represents either tele or bearer service usage terminated by the mobile subscription.  In some cases the mobile itself may not be directly involved, e.g. some call forwarding scenarios.

Mandatory elements are the MT Basic Call Information and the Basic Service Used.  Only one basic service will be present and it will not be possible, for example, to distinguish between the data and speech parts of alternate services.

Note:  There must be only one occurrence of the Basic Service Used group within this group even though the physical syntax indicates that this may be a repeating group.

Location Information and Equipment Identifier will normally be present except, for example, where the call does not terminate at the equipment e.g. call forward on no reply.

Where CAMEL services are supported and invoked then one occurrence of CAMEL Service Used will be present for the invocation.

Operator Specific Information may also be present, this is optional dependent on bilateral agreement.

Conditionality:

Mandatory within an occurrence of group Call Event Details where none of the following are present;  Mobile Originated Call, Supplementary Service Event, Service Centre Usage, GPRS Call, Content Transaction or Location Service.
