Therefore, we need a global system – the IMS.
P-CSCF plays an important role in IMS emergency session handling as the P-CSCF is tasked to detect emergency requests in all possible cases and to select E-CSCF to handle the emergency session further. Interrogating Call Session Control Function: I-CSCF is a contact point within an communication service provider’s network for all connections destined to a subscriber of that network communication service provider. There are three unique tasks assigned for the I-CSCF: • Obtaining the name of the next hop (either S-CSCF or AS) from the HSS.
By sending a path switch request the target eNodeB indicates to the MME that the S1 interface needs to be switched from the source eNodeB to the target eNodeB. The MME updates the S-GW with the new eNodeB address information for the downlink of the user plane and conﬁrms the relocation of the S1 interface towards the target eNodeB with a path switch ack (acknowledgement). The MME may also allocate a different S-GW and provide the target eNB with the necessary address information for the uplink of the user plane in the path switch ack message.
