114.2.6 MMS KPIs

For MMS, the KPI structure is more complex and multi-tiered than for the other services; the top-level KPI (MMS End-to-End Delivery Time) spans both sending, notifying, and receiving.
The MMS session setup involves WAP activation, so the WAP KPIs (see section "WAP KPIs" above) are computed for MMS also.
The following KPIs are MMS-specific:

114.2.6.1. MMS Send Failure Ratio (MO) (%)

Denotes the probability that the subscriber cannot send an MMS message despite having requested to do so by pushing the "send" button.
(The chain of operations is: PDP Context Activation > Service Access > WAP Activation > MMS Send.)

114.2.6.2. MMS Send Time (MO) (s)

Denotes the length of time (in seconds) elapsing from the moment the sender pushes the "send" button until the MMS data transfer to the MMSC is completed.

114.2.6.3. MMS Notification Failure Ratio (%)

Denotes the probability that the Multimedia Messaging Service is not able to deliver a notification of a successfully sent MMS message to the receiving party's phone.

114.2.6.4. MMS Notification Time (s)

Denotes the length of time (in seconds) elapsing from the moment the MMS data transfer to the MMSC is completed until the receiving party receives the MMS notification.

114.2.6.5. MMS Retrieval Failure Ratio (MT) (%)

Denotes the probability that the MMS message cannot be downloaded by the receiving party's phone, although the latter has received an MMS notification.

114.2.6.6. MMS Retrieval Time (MT) (s)

Denotes the length of time (in seconds) elapsing from the WAP Get Request until the completion of the MMS download from the MMSC.

114.2.6.7. MMS End-to-End Failure Ratio (%)

Denotes the probability that an MMS cannot be conveyed successfully from sender to receiver, that is, a failure occurs somewhere along the line after the sender has pressed the "send" button and before the receiver is able to download it.

114.2.6.8. MMS End-to-End Delivery Time (MO/MT) (s)

Denotes the length of time (in seconds) elapsing from the moment the sender pushes the "send" button until the receiver has completed the MMS download from the MMSC.
