Apparatus and method for acquiring ipv6 domain name system server and sip server address

Abstract

A mobile communications device, operating as a Mobile Terminal (MT), is provided. In the mobile communications device, a receiver is configured to receive a DHCPv6 INFORMATION-REQUEST message from a Terminal Equipment (TE). A processor is configured to generate a DHCPv6 REPLY message when the MT gets at least one of an IPv6 DNS and a SIP server address. In addition, a transmitter is configured to transmit the DHCPv6 REPLY message to the TE. In operation, the MT transmits the DHCPv6 REPLY message to the TE according to at least one of the DNS and SIP server address from a service network or pre-stored in a memory.

What is claimed is: 
     
         1 : A mobile communications device, operating as a Mobile Terminal (MT), comprising:
 a receiver, configured to receive a DHCPv6 INFORMATION-REQUEST message from a Terminal Equipment (TE);   a processor, configured to generate a DHCPv6 REPLY message when the MT gets at least one of an IPv6 DNS and a SIP server address; and   a transmitter, configured to transmit the DHCPv6 REPLY message to the TE,   wherein the MT transmits the DHCPv6 REPLY message to the TE according to at least one of the IPv6 DNS and SIP server address from a service network or pre-stored in a memory.   
     
     
         2 : The mobile communications device of  claim 1 , wherein the memory is configured to store at least one of the pre-stored IPv6 domain name system (DNS) and the pre-stored SIP server addresses. 
     
     
         3 : A mobile communications device, operating as a Mobile Terminal (MT), comprising:
 a receiver, configured to receive a DHCPv6 INFORMATION-REQUEST message from a TE;   a transmitter, configured to transmit the DHCPv6 INFORMATION-REQUEST message to the service network;   a processor, configured to modify a DHCPv6 REPLY message transmitted from the service network according to at least one of an IPv6 DNS and a SIP server address from the service network or pre-stored in a memory; and   wherein the MT transmits the modified DHCPv6 REPLY message to the TE.   
     
     
         4 : The mobile communications device of  claim 3 , wherein the memory is configured to store at least one of the pre-stored IPv6 domain name system (DNS) and the pre-stored SIP server addresses. 
     
     
         5 : A method for at least one of an IPv6 DNS and a SIP server address acquisition by a mobile communications device operating as a Mobile Terminal (MT), comprising:
 receiving a DHCPv6 INFORMATION-REQUEST message from a TE;   generating a DHCPv6 REPLY message when the MT gets at least one of an IPv6 DNS and a SIP server address;   transmitting the DHCPv6 REPLY message to the TE; and   wherein the DHCPv6 REPLY message is transmitted according to at least one of the IPv6 DNS and SIP server address from a service network or pre-stored in a memory.   
     
     
         6 : The method of  claim 5 , further comprising:
 storing at least one of the pre-stored IPv6 domain name system (DNS) and the pre-stored SIP server addresses in the memory.   
     
     
         7 : A method for at least one of an IPv6 DNS and a SIP server address acquisition by a mobile communications device operating as a Mobile Terminal (MT), comprising:
 receiving a DHCPv6 INFORMATION-REQUEST message from a TE;   transmitting the DHCPv6 INFORMATION-REQUEST message to the service network;   modifying a DHCPv6 REPLY message transmitted from the service network according to at least one of an IPv6 DNS and a SIP server address from the service network or pre-stored in a memory; and   transmitting the modified DHCPv6 REPLY message to the TE.  8 : The method of  claim 7 , further comprising:   storing at least one of the pre-stored IPv6 domain name system (DNS) and the pre-stored SIP server addresses in the memory.
