ABSTRACT:
A method of a user terminal obtaining its access location information in next generation network, and a user terminal, and a server having function of Dynamic Host Configuration Protocol (DHCP) function are disclosed. DHCP is extended by adding a new DHCP option to carry the user terminal access location information; when the user terminal accesses to network, DHCP server puts the DHCP option into DHCP response message; receiving the DHCP response message, the user terminal obtains the access location information from the DHCP option. The present invention overcomes the shortcoming of the prior art that when a terminal nomadizes or roams from one access network to another, the access network information configured on the terminal has to be updated manually and thus results in redundant workload and inflexibility, the user terminal is allowed to obtain its access location information automatically, hence nomadicity or roaming of the user terminal is supported.
