Abstract:
A method for maintaining IP address negotiations in a wireless communication network, said method comprising:receiving, in a communication device, a message requesting an IP address from a terminal device, said terminal device coupled to said communication device; generating, in said communication device, a message requesting an IP address from said communication network in response to said IP address request message; and determining whether said communication device has received an assigned IP address from said communication network, wherein, in response to determining that said communication device has not received said assigned IP address, said communication device repeatedly transmits a message with an arbitrary IP address to said terminal device to trigger said terminal device to respond by transmitting IP address request messages with said arbitrary IP address and said communication device rejects said arbitrary IP address in said IP address request messages until said communication device has received said assigned IP address from said communication network.
