What is the difference between Router and Filter?

Question

Depending on the packet filter, it is decided to which bearer does the incoming packet belongs to. If TFT does this job, then what is the use of Pcc-Rule ?

Is it that Pcc-Rules are not matched in case of dedicated bearers as in dedicated bearer packet filter are already matched ?
Is it that DPI is done only for default bearer packets and decided to which pcc-rule is belongs to ?

Please help with reference to spec...

Answer 1

Diff between Router and Filter:

Router transformation provides the division of the incoming records into multiple groups using the condition mentioned, whereas Filter transformation doesn’t take care of division.

• Router transformation provides mutually inclusive groups to have the same records, whereas Filter transformation used to restrict the incoming record.

• Router transformation doesn’t block the incoming record, whereas Filter transformation blocks or restricts the incoming record on the condition given.

• Router transformation doesn’t block the record that is being used, whereas Filter transformation doesn’t provide the default groups.

• Router transformation allows the record that doesn’t match the routing conditions, whereas Filter transformations are used not to match the condition.
