    Abstract: An embodiment method for session handling for a connection between an UE and a network includes establishing, at a first distributed EPC, user and IP sessions over the connection through the first distributed EPC. The first distributed EPC includes a first PGW at which the IP session is anchored. The method also includes holding original IP resources and releasing original connection resources for the sessions at the first distributed EPC when the UE moves beyond the first distributed EPC to a second distributed EPC. The method then establishes a tunnel between the first PGW and a second PGW for the second distributed EPC. The tunnel utilizes the original IP resources and new connection resources at the second distributed EPC. The method then routes data from the tunnel, through the first PGW, and to the network.

    Abstract: Embodiments are provided for a mechanism for supporting multiple 3GPP Packet Data Network (PDN) connections over a WLAN. Multiple gateway interfaces, each corresponding to a different PDN, are established over a single connection , via the WLAN, between a UE and an access gateway. A PDN access configuration protocol (PACP) is provided to configure the association between the IP interface on the access gateway and the corresponding 3GPP PDN/APN connection, and exchange the PDN setup between the UE and the access gateway. The PACP mechanisms allow signaling APN information and associating corresponding IP context at the access gateway, setting up and tearing down connection context between the UE and PDN gateway (P-GW), and supporting session continuity when the UE moves to another access gateway. The mechanisms support using Dynamic Host Configuration Protocol (DHCP) for IPv4 and Neighbor Discovery for IPv6.

    Abstract: Internet protocol (IP) address allocations in distributed EPC networks can be published to an IP address registry maintained at the central EPC entity in order to facilitate the routing of authentication authorization, and accounting (AAA) signaling of third party networks throughout the distributed EPC network architecture. The address allocations can be published directly to an address registry maintained by the central EPC entity, or indirectly via a cloud management server. Additionally, latencies associated with UE authentication in distributed EPC network architectures can be mitigated by triggering communication of the authentication or authorization profile upon reception of an update location request (ULR) message at the central EPC network entity.
