Abstract: One illustrative method of for use in controlling network resources in a wireless network involves assigning, from a pool of IP addresses, a temporary IP address for a mobile station in the wireless network; calculating a ratio or percentage of the number of IP addresses and the total number of IP addresses in the pool; setting a timer value for the mobile station to an initial value that 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 timer value to be sent to the mobile station, which is adapted to register the temporary IP address with a home agent for IP mobility service; and communicating a termination request which terminates the IP mobility service if no request for re-registration is received from the mobile station upon expiration of the timer value.

Abstract: Methods are provided for transitioning between SIP and MIP. Mobile devices, upon detecting a new system, automatically attempt a MIP session to avoid the default position of SIP. A history is maintained of systems visited, and for systems that did not support MIP in the past, a MIP session is not attempted, but rather SIP is initiated from the start.

Abstract: A method and system of providing a mobile data device in a wireless system with information about preferred networks to connect to, the mobile device having a preferred roaming list with a list of networks, the method comprising the steps of: adding to the preferred roaming list information about whether each network in the list of networks supports third generation data capabilities; and determining preferred networks based on information within the preferred roaming list including a geographic area and whether the network supports third generation data capabilities, whereby, within the geographic area, the mobile device prefers networks which support third generation data capabilities over networks which do not support said third generation data capabilities. Other information that may be added to the preferred roaming list includes whether the network supports data roaming, Mobile-IP services or always-on features.

Abstract: Techniques for controlling wireless network operations associated with a flow control process of a wireless network involving a data session established between a mobile station and a service node. The network processor examines quality of service (QoS) data associated with the data session. The network processor causes the flow control process to be bypassed for the mobile station based on the QoS data indicating that the data session is associated with a predetermined traffic class (e.g. background traffic class). This serves to prohibit the flow control process from stopping the flow of data packets in the data session without terminating the data session based on detection of an out-of-coverage condition. Otherwise, the network processor allows the flow control process to be performed for the mobile station based on the QoS data indicating that the data session is not associated with the predetermined traffic class.
