ABSTRACT:
A DHCP server allocates IP addresses to DHCP clients and the IP address validation process is moved from the client to the DHCP server. The DHCP server is required to periodically select a predefined number of validated IP addresses from its unused IP addresses. When a client applies for an IP address, the DHCP server allocates an IP address from its selected validated IP addresses to the client, and the client then directly uses the IP address allocated by the DHCP server. This method may be used for providing VoIP in mobile phones, wherein the voice session interruption is shortened sufficiently before the mobile terminal acquires a new IP address through the fast IP address re-allocation to a mobile terminal, thereby ensuring mobile VoIP communication quality.
