The charging mode of the SM origination service for Prepaid Service (PPS) subscribers of China Mobile fails to satisfy the requirement for some subscribers to send abundant SM advertisements within a short time using the dedicated equipment. The sending mode of SM advertisements originated from the dedicated equipment causes great interference on network running. Therefore, it is required to discriminate these malicious SMs through warning so that the operator can take corresponding measures. The function generates warning for all malicious SM subscribers, without distinguishing prepaid service subscribers and postpaid service subscribers. Within the statistical time period, the system only sends the warning to each malicious MS subscriber once to avoid frequent warning.

 

In the MSOFTX3000, the subscriber can discriminate possible malicious SM subscribers by configuring the threshold of SMs originated by a subscriber within a time period. That is, within the statistical time period, if the number of SMs sent by a subscriber exceeds the threshold, the MSOFTX3000 reports warning.

 

Implemented node: VMSC/VLR

 

Served network: GSM and UMTS

 

Service benefits: Obtain the list of malicious SM subscribers and avoid further losses by taking corresponding measures.

 

Requirements for peripheral network entities: None

Can we use anti spam software for overcome this?

I think by subscribers here you mean 3rd party content aggregators sending SM to operator network subs, or you mean individual subscribers ?
