Each node has its hardware and software limitation. Based on the circle size and number of expected subscribes, operator does planning and they deploy different kinds of nodes in their network. Based on type of service, PGW selection is done at MME. But actual number of PGWs might be more to avoid single point of failure.
As per my knowledge, PGW is selected based on the type of service UE is asking and also which node is best suited to serve a request in case more than one PGW are available to serve the same service. SGW is selected by MME based on the location of UE.

Does core network need to implement GTP-based or PMIP S5/S8 interface if it is combined S-GW/P-GW?

Hi all

Because combined S-GW/P-GW is one node, so do we still need to implement the connection between them?
Is it necessary for core network to implement GTP-based or PMIP based S5/S8 interface if it is combined S-GW/P-GW?

Is there any 3GPP spec mention about combined S-GW/P-GW? what is the cons and reasons to do this?

thanks
