摘要：
A method for releasing an Internet Protocol Address (IP Address) by a packet data network gateway (PGW) in mobile network, comprises allocating an IPv4 address and an IPv6 address to a User Equipment (UE) to activate a Packet Data Network (PDN) connection between the UE and the PGW. If the UE release the IPv4 address, transmits to a serving gateway (SGW) a binding revocation message comprising an indication to release only the IPv4 address from the PDN connection to SGW. The SGW may release the IPv4 address; and a release of resources corresponding to the IPv4 address may be triggered.
