A GGSN receives a request associated with a session creation for a mobile entity. The GGSN begins a process (a four-way handshake) for obtaining network access configuration parameters for the mobile entity and responds to the request prior to the completion of the four-way handshake. The GGSN then completes the four-way handshake. A GGSN creates an association between a first IP address and a first mobile entity and thereafter requests an IP address for a second mobile entity. In response thereto, the GGSN receives the first IP address, which the GGSN declines for the second mobile entity and reserves for the first mobile entity. The GGSN requests an IP address for the second mobile entity a second time and receives a second IP address that is different from the first IP address.
