Abstract: A power management system is described where the handset can enter sleep or hibernation mode for a particular service, when the particular service is either not used or not available. The handset is capable of using the service, even in response to a non-user initiated incoming request for communication. The handset receives the request over the active service. The handset can then check for the availability of the inactive service, activate it, and a selection can be made between them.

Abstract: A system and method for transmitting data packets to a wireless client is shown. The data packets are received by a wireless content switch in the wireless network. The wireless content switch determines a quality of service value for the wireless client. The wireless content switch assigns the priority of transmission for the data packet based on the assigned quality of service value. The data packet is transmitted according to the priority.

Abstract: A system and method for optimizing a multimedia transmission from a content source to an end user over a link. The wireless content switch comprising an upstream port for receiving one or more data packets and for transmitting one or more status to a content source, a downstream port for transmitting the one or more data packets and for receiving one or more status from an end user, at least one processing unit coupled to the upstream and down stream ports, and memory for storing the one or more data packets responsive to receiving the data packets. Optimization code is stored in the memory, the optimization code, when executed, receiving at least one data packet, transmitting the data packet, receiving status information, transmitting status information, determining quality of service assigned to the end user, determining session specific status for the end user, and transmitting the quality of service and session specific status.

Abstract: A system, method, and apparatus for transmitting packet data over a wireless network to a mobile station is presented herein. Packet data are received at a wireless content switch that is part of the wireless data network. The wireless content switch is equipped to detect lost packets, lost acknowledgments, and take appropriate remedial action, without invoking the congestion control and avoidance mechanisms of the transmission control protocol.

Abstract: A technique as well as associated systems, methods, and apparatuses for preventing an overflow of data packets at a plurality of nodes in a wireless data network is presented herein. The amount of available allocated memory at the plurality of nodes for a wireless client is monitored by a wireless content switch. The wireless content switch also intercepts a signal transmitted from the wireless client which indicates the amount of available memory at the wireless client. The wireless content switch modifies the signal such that the indicated amount of memory does not exceed the amount of memory allocated at the plurality of nodes for the wireless client.

Abstract: A method and apparatus for measuring application performance over a wireless data network is presented herein. A wireless content switch is placed between a wired network and a wireless client such that data packets sent from the wired network to the wireless client and vice versa are received at the wireless content switch. The wireless content switch examines the protocol stack and data associated with the data packet and measures the performance of applications. The performance of applications is measured using one of a plurality of measures, based on the type of application associated with the data packet. Wherein an application is found to be associated with low performance, graceful degradation can be imposed.

Abstract: A system for processing wireless packet data is provided. The system includes a gateway radio packet interface receiving radio packet data from a gateway radio packet node. A content switch system coupled to the gateway radio packet interface receives the radio packet data, extracts one or more predetermined data fields from the radio packet data, and performs one or more predetermined actions based on the extracted data fields. A serving radio packet interface coupled to the content switch system transmits the radio packet data to a serving radio packet node.
