A content capability clearing house that can act as a trusted and neutral mediator among network providers to manage rich content capabilities among multiple networks is provided. Content capabilities that can be brokered include, but are not limited to, quality of service and content screening. In an embodiment, a content capability clearing house includes a receiver that receives content capability request messages and other messages from network providers. A content capability request message includes a quality of service request and/or a subscriber profile request for use with content screening and subscriber specific advertisements. The present invention includes a series of methods for determining content capabilities for data transmission over a transaction between a content provider and a subscriber in which a content capability clearing house is used to efficiently broker and manage the capability among multiple network providers.

A system and method are described whereby interoperability is facilitated in a 3GPP network environment in combination with DIAMETER policy controls. Such interoperability enables updated policy rules to be fully communicated in on-line charging situations where quota expirations occur. This invention maintains centralized policy control in a 3GPP network with on-line charging.

Systems and methods subscriber profile management to facilitate seamless roaming of mobile devices from one network to another. A subscriber profile management system is provided that includes a time to live ('TTL') generator that generates a TTL limit for a subscriber based on usage characteristics of the subscriber. The subscriber profile management system further includes an administration module that administers TTL limits, TTL limit database that store TTL limits, a subscriber profile database that stores subscriber profiles, a usage measurement database that stores usage measurements, and a TTL limit reference module that administers TTLs when a subscriber profile and TTL limit are transmitted. The invention further includes a series of methods that support seamless roaming capabilities of a subscriber throughout visited networks without the need to continually make proxy calls to re-authenticate a subscriber.

Wireless data services such as wireless email are becoming common, and in particular, 'always-on' systems, where new email is automatically forwarded by the service provider to the wireless device. The problem is that there is no effective mechanism for implementing 'always-on' systems when the user is moving around a network, or from one network to another. The invention addresses this problem by generating a session key at the service provider's system for a given data session, and returning this session key to the mobile device. Each time the mobile device communicates with the service provider, it enters this session key into a field that will simply pass through the communication network to the service provider. This allows the service provider to manage the data session, preparing proper accounting records and directing the deletion of stale data sessions on network resources.

Efficient network resource management in a wireless network

A billing mediation system for use within a communications network that correlates session records pertaining to usage of network resources is disclosed. The billing mediation system includes a record receiver, a record correlator, a look ahead cache, a set of buffers, and a session records database. The set of buffers includes a single segment insert buffer, a multi segment insert buffer, a multi segment update buffer and a billing finalization update buffer. A method for correlating session records is also provided. The method includes receiving a session record, placing the session record into a segment buffer based on the type of record, and updating a look ahead cache including providing a timestamp for the last update for a session. The transfer of correlated session records to a billing system is based on whether records for a session have been received based on session tracking within the look ahead cache.
