8.1 Interaction with barring services
Barring services described in 3GPP TS 23.040 are prior to VAS-SMS services. Any related VAS-SMS service to Operator Determined Barring (see 3GPP TS 22.041 ) is not applicable when Operator Determined Barring applies to the Short Message Service. For example, if an originating service for SMS is barred by ODB and a terminating service for SMS is not barred, all the related originating services for VAS-SMS service are also barred, but terminating services (e.g. SMS forwarding) for VAS-SMS are not impacted.
8.2 Interaction with multiple Short Message transfer
There is no direct conflict between the VAS-SMS service and the multiple short message transfer service described in 3GPP TS 23.040. VAS-SMS services shall not impact the implementation of the multiple short message transfer service when the SMS-SC indicates to the SMS-GMSC that there are more messages to send for each message waiting in the service centre.
8.3 Interaction with SMS COMPRESSION
VAS-SMS services should be applicable for the SMS COMPRESSION described in 3GPP TS 23.040. If the VAS-SMS service does not support SMS COMPRESSION (for example for VAS-SMS services that modify the content of a SM), then it shall guarantee the compressed SMS message delivery as normal.
8.4 Interaction with Enhanced Messaging Service
For the enhanced messaging service described in 3GPP TS 23.040, VAS-SMS services should be applicable. If the VAS-SMS service does not support the enhanced messaging service (for example for VAS-SMS services that modify the content of a SM), then it shall guarantee enhanced message delivery as normal.
8.5 Interaction with SM delivery report
If a Short Message Receipt service is applied the SMS Node shall not send SM delivery report message to the user.
8.6 Interaction with charging
VAS-SMS services are required to produce billing of extra fee (e.g. monthly based function fee).
8.7 Interaction between VAS-SMS services
VAS-SMS services should be classified by priority and triggered according to priority order based on operator’s policy.
