摘要： Methods for pipelining, piggybacking, and transporting cross layer parameters through a network to reduce round-trip times are disclosed. Application activation, such as accessing a web-site through the internet, currently uses several protocols, including DNS Name resolution, establishing a TCP connection, sending HTTP Request and getting HTTP-Response that contains the web-page data, before the data from the web-site can be displayed to the user. Such operations take several round-trips through the transit network and are of the order of 100 to 200 milliseconds in the wireless access network in the best case. A method of generating a multi-part message to reduce these round trip is disclosed, as well as a proxy device which minimizes client side round trips while utilizing standard messaging in the wireline network. The invention includes client side user parameter gathering when specifying the application first (pre-fix), or specifying the application last (post-fix).

摘要： A method for delivering content to a user from a Radio Access Network (RAN) cache without waiting for a response from the content server if the user's request meets the criteria of caching and expiration tags on previously cached content. If there is no cached copy of the content in the local device, the local device may treat the request as a cache miss, propagating the user's request and the corresponding response through one or more core network devices for accounting and/or charging. In the case of a cache hit, the local device may return the requested object from local cache and may forward each user content request to the content provider so that the mobile network's accounting devices can register the appropriate charge to the user's account. The local device may then update the RAN cache and expiration timers based on the response from the content servers.

摘要： A method of generating optimal packet workload for achieving a balance between maximizing cell throughput and fairness across multiple users in UMTS/HSPA Network is disclosed. The packet scheduler of the current invention enhances the performance of other schedulers, such as Proportionally Fair Scheduler in NodeB and RNC in UMTS/HSPA Networks by monitoring recent RAN bandwidth to each mobile device, and increasing buffer occupancy of high rate data-flows in the RAN devices. The scheduler uses the desired performance goals of maximum cell throughput and fairness at various network congestion levels, and controls egress burst rate while delivering packets to the RAN (Radio Access Network).
