During call proceeding, calling party originates multimedia call. When network finds the following cases, multimedia call falls back to common calls.

 

  • Called terminal does not support VP call.
  • Called party is unwilling to receive call in VP mode.
  • Called party does not subscribe to VP service.
  • Called party roams to GSM network.
  • Called party is switched over to GSM network during VP call.

 

This function can be applied in R99 and R4 networking.

 

Implemented node: VMSC/VLR, GMSC, and TMSC

 

Served network: UMTS

 

Service benefits:

 

For carriers:

Call completion rate between 3G subscribers and subscriber satisfaction can be improved obviously.

 

For subscribers:

Simplify multimedia service operations.

 

Requirements for peripheral network entities: None
