Abstract
Various embodiments relate to a system and related method for handling requests from a user device in a wireless communications network. Various embodiments relate to a Policy and Charging Rules Node (PCRN) attempting to bind an IP-CAN session established in a Packet Data Network gateway (PGW) with a gateway control session established in a serving gateway (SGW). In instances when the IP-CAN session and gateway control session no longer match, the PCRN may wait to receive a subsequent message from the PGW and/or SGW. When the PCRN does not receive the subsequent message containing a matching session, the PCRN may terminate the sessions in all the relevant gateways. This may cause the system to reestablish a new, matching connection instead of remaining in a hanging state.
