MobileOriginatedCall

Validations ASN.1 Parent Types

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

The Mobile Originated Call must contain the MO Basic Call Information, Location Information and Basic Services Used.  Where a call is set up requesting dual service capability, Dual Service Requested is provided in addition to each basic service used.

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

Where supplementary services are used in conjunction with a call and these are deemed necessary for transfer (see Annex A) then there will be one occurrence of Supplementary Service Used present per invocation.

If the call was in respect of a value added service and there is a bilateral agreement between the VPMN and the HPMN then there will be one occurrence of Value Added Service Used per service used.

Equipment information will normally be transferred.  The reason that it may not be present is because the call did not originate from the equipment.

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 Terminated Call, Supplementary Service Event, Service Centre Usage, Value Added Service, GPRS Call, Content Transaction or Location Service .
