Abstract
Methods and systems for providing network connectivity in wireless networks are provided. This network connectivity can involve a mobile node being able to connect with more than one network at the same time and supporting multiple protocol sessions. Additionally, modifications can be made to allow a mobile node to have multiple IP addresses. These modifications include using a packet data network identifier along with a network control protocol to allow a network device to provide to user equipment (UE) multiple packet data network connections. The network device can be a access gateway or HPRD serving gateway (HSGW) that sets up the PDN connections for the UE. The packet data network identifier can be used to distinguish between multiple PDN connections for a UE.
