Abstract:
1. A method for use in controlling network resources in a wireless network for a mobile station operating for communications in a data session, the data session being associated with a data inactivity timer for terminating the data session, the method comprising: assigning, from a pool of IP addresses utilized in the wireless network, a temporary IP address for the mobile station in the wireless network, the mobile station having a home IP address associated with a home network; calculating a ratio or percentage of the number of IP addresses assigned to mobile stations in the wireless network and the total number of IP addresses in the pool; setting a registration duration timer value for the mobile station to an initial value that is less than the data inactivity timer of the data session and depends on the ratio or percentage of IP addresses such that, as the ratio or percentage increases, the initial value decreases; causing the temporary IP address and the registration duration timer value to be sent to the mobile station, wherein the mobile station is configured to register the temporary IP address with a home agent in the home network for IP mobility service, so that data packets of the data session which arc addressed to the home IP address are tunneled to the temporary IP address of the mobile station in the wireless network; and communicating a termination request which terminates the IP mobility service when no request for re-registration is received from the mobile station upon expiration of the registration duration timer value.
