context: connectivity, an "EPS default bearer charging identifier", - in case of PMIP based connectivity, an "unique Charging Id" is assigned by the P-GW and transferred to the TDF via the PCRF for the TDF session. During handover of a PDN connection between a GTP based connectivity access, and a PMIP based connectivity access for the P-GW (and reversely), the "EPS default bearer charging identifier" and the "unique Charging Id" respectively, are maintained in order to ensure charging continuity for the whole PDN connection over the different accesses. Upon handover from GTP based connectivity to PMIP based connectivity, the previously assigned "EPS default bearer charging identifier" is used as the "unique Charging Id". Upon handover from PMIP based connectivity to GTP based connectivity, the previously assigned "unique Charging Id" is used as the "EPS default bearer charging identifier". During handover of a PDN connection between a GTP based connectivity 3GPP access, and a S2a/S2b GTP based
description: Proxy Mobile IP (PMIP) is a protocol used for mobility management in telecommunications networks. It allows mobile devices to maintain connectivity while moving between different network accesses, ensuring seamless handovers and charging continuity.
explanation: The text explicitly states that PMIP is a "protocol" used for mobility management, which aligns with the definition of a protocol as a set of rules governing communication between entities.
