Abstract: The present invention provides for mapping of plurality of IP flows to a plurality service instances. A plurality of IP flows are received at a PDSN. The header information associated with each IP flow at the PDSN is parsed. Each IP flow is mapped to its corresponding service instance. The mapping criteria are defined by a flow filter. The flow filter can be generated within the PDSN, or outside of the PDSN such as by an MS. Each IP flow is transmitted on its corresponding service instance to its endpoint, such as an MS.

Abstract: A mobile communications network includes various entities, such as a mobile station, a radio network, and a packet data node. In one implementation, the mobile station is enabled for an always-on service. In response to detecting that the mobile station is an always-on mobile station, the packet-data node denies requests from the radio network to tear down a packet data session of the mobile station unless some predetermined criterion has been met.

Abstract: According to a method of controlling access to a prepaid packet data communication service, a prepaid server transmits a resource response in response to receipt of a resource request for prepaid resources from a prepaid client. The resource response specifies a quota of prepaid resources no greater than a prepaid account balance of a prepaid service subscriber and a resource usage threshold at which the prepaid client provides notification. The prepaid client then receives a notification from the prepaid client indicating that the threshold of prepaid resources has been reached, and in response to the notification, performs an accounting updating reflecting a portion of the prepaid account balance that has been consumed.

Abstract: The present invention provides for the discovery of an Internet Protocol (IP) address of an application server associated with an IP network. An IP device is granted access to an IP network. Access to the IP network assumes an IP address assignment for the IP device. The network domain name is discovery by performing a Reverse DNS query on the assigned IP address or an IP address associated with the IP network device granting access to the IP device. Using a application server domain name (derived from the network domain name) a DNS query is perform to determine all IP addresses associated with the application server domain name.
