摘要： Techniques for maintaining an always-on data session for an access terminal are described. Messages to keep alive the data session may be sent using non-traffic channels to avoid bringing up traffic channels just to send these messages. In one design, an access network may send a first message (e.g., a RouteUpdateRequest message) on a first non-traffic channel (e.g., a control channel) to the access terminal. The access terminal may return a second message (e.g., a RouteUpdate message) on a second non-traffic channel (e.g., an access channel) to the access network. The access network may then send a third message (e.g., for an Echo-Request) on the first non-traffic channel over a smaller area covering an approximate location of the access terminal, which may be determined based on the second message. The access terminal may return a fourth message (e.g., for an Echo-Reply) on the second non-traffic channel to the access network.

摘要： Systems and methods for automatically providing different levels of Quality of Service (QoS) to applications in a communication network having various content providers. Typically, content is provided to applications that are unable to specify applicable QoS. A service node is provided to coordinate transfer of data to the applications. The service node further cooperates with an access terminal running the applications to specify the QoS.

摘要： The disclosure relates to techniques for maintaining minimum quality of service (QoS) communication sessions with a wireless communication device (WCD) over a data-based communication network during a hard handoff between access networks for the WCD. More specifically, the techniques determine whether a closed connection between the WCD and a first access network during a minimum QoS communication session is due to a hard handoff between the first access network and a second access network. In the case of a hard handoff, the techniques maintain open QoS reservations associated with data flows included in the minimum QoS communication session for a predetermined period of time to enable a new connection to be established between the WCD and a second access network. The techniques described herein may especially useful when performing a voice over Internet Protocol (VoIP) call over an Evolution-Data Optimized (EVDO) communication network.

摘要： Techniques to detect for end of service using dynamic inactivity timer thresholds are described. An access terminal establishes a radio connection for one or more applications. Data and signaling for the application(s) may be sent on one or more first flows (e.g., RLP flows) that may carry any number of second flows (e.g., IP flows). The access terminal determines a dynamic inactivity timer threshold for each first flow, e.g., based on at least one inactivity timer threshold for at least one second flow mapped to that first flow. The access terminal determines whether each first flow is inactive based on the inactivity timer threshold for that first flow, e.g., declares each first flow to be inactive if no activity is detected on that first flow for a period exceeding the inactivity timer threshold. The access terminal closes the radio connection when all first flow(s) are determined to be inactive.

摘要： Method for the preparation of inorganic-NP-composite microgels is based on the reversible transfer of microgels between water and an organic solvent such as tetrahydrofuran (THF). The method is used to produce semiconductor nanocrystals, often referred to as quantum dots (QDs) which are well known for their unique optical, electrical, magnetic and catalytic properties, as the inorganic NPs, recognizing that the best quality QDs are synthesized by a high temperature process in organic media, and have their surface covered with hydrophobic ligands (such as trioctylphosphine oxide, TOPO) that render the NPs insoluble in an aqueous solution.
