Abstract:
A method of communication involves sending (204) a request from a first network entity (e.g., a femto convergence server) to a second network entity (e.g., a home subscriber server) for user data relating to an access point, receiving (208) a response to the request, wherein the response identifies at least one application server, and sending (210) registration status information to the identified at least one application server.
Abstract:
Systems and methodologies are described that facilitate supporting VPLMN-autonomous CSG roaming in a wireless communication environment. A UE can access a CSG list server associated with a VPLMN. A trust relation can be established between the UE and the CSG list server, for example. Moreover, the CSG list server can update a VPLMN allowed CSG list associated with the VPLMN stored by the UE. Hence, the UE can receive the VPLMN allowed CSG list from the CSG list server associated with the VPLMN. Further, the UE can store the VPLMN allowed CSG list as part of an allowed CSG list. The VPLMN allowed CSG list can include one or more entries associated with the VPLMN. Moreover, the allowed CSG list can be under control of at least one operator and the UE.
Abstract:
This disclosure enables a radio access network to control media data rates and codec parameters selected during multimedia session establishment. As the load on a radio network changes, operators desire to have the ability to control what data rate new multimedia sessions (e.g., VoIP) are to utilize, thereby allowing the operator to conduct a trade-off between voice/video quality and capacity during heavy loading periods. The multimedia communication session may be initiated with a determined guaranteed bit rate, where the guaranteed bit rate is requested, negotiated as one of several acceptable guaranteed bit rates, or based upon maximum system capacity, to take advantage of maximum data rate for the equipment in use. The session may also be initiated with a determined Quality of Service based upon either a network or user equipment installed policy.
Abstract:
Information is maintained to assist in determining whether an access terminal is allowed to establish communication with an access point associated with a closed subscriber group (CSG). For example, CSG subscription information for visiting access terminals may be maintained at a local server. In this way, a network may use the locally stored CSG subscription information for a given access terminal to determine whether to allow that access terminal to access an access point in the network. In addition, multiple CSG lists may be maintained at an access terminal. For example, an access terminal may maintain a first list that is updateable by an operator and a second list that is updateable by a user. Here, the updating of one list may be based on a change in the other list.
Abstract:
Techniques for supporting eCalls are described. In an aspect, an eCall indicator may be used to indicate an eCall being established. In one design, a terminal may generate a message including an eCall indicator and may send the message to originate an eCall. The eCall indicator may indicate (i) whether or not a call is an eCall or (ii) whether an eCall is initiated automatically by the terminal or manually by a user. In another aspect, a terminal may avoid sending signaling for mobility management and connection management to wireless networks except for eCalls and designated calls. The terminal may avoid performing location updating, performing registration, responding to paging requests, etc. The terminal may exchange signaling with a wireless network for an eCall initiated by the terminal. After the eCall is initiated, the terminal may perform location updating with the wireless network and call establishment for the eCall.
Abstract:
Techniques for archiving data exchanged between a terminal and a wireless communication network during a session are described. Session data may be archived at a network entity in real-time while the session is in progress or may be uploaded to the network entity for archival after the session has terminated. The network entity may archive all data exchanged during the session or only data of the terminal, depending on whether authorization is received from other terminals in the session. The network entity may assign an identifier for the session and may store the identifier and other attributes for the session. During or after the session, the network entity may receive from the terminal a request for all or a portion of the archived data and would then provide the requested data. The network entity may archive a single copy of the session data for all terminals in the session.

Abstract:
A reversible hydrogen storage alloy capable of absorbing approximately 4 weight percent hydrogen and desorbing up to 2.8 weight percent hydrogen at temperatures up to 100° C. The hydrogen storage alloy is generally composed of titanium, vanadium, chromium, and manganese. Additional elements such as zirconium, yttrium, iron, nickel, zinc, molybdenum, and tantalum may also be included in the alloy.
Abstract:
A hydrogen gas cooled hydrogen storage element which includes a hydrogen storage alloy material in which hydrogen flow channels are provided. The flow channels provide pathways through the hydrogen storage material to allow for high speed hydrogen gas flow. A portion of the high speed hydrogen flow is stored within the storage material which releases its heat of hydride formation. The remainder of the hydrogen flows through the hydrogen storage material at a sufficient mass flow rate to remove the heat of hydride formation.
Abstract:
Mechanically alloyed hydrogen storage materials having a major atomic percentage of magnesium and a minor atomic percentage of at least two elements selected from the group consisting of nickel, molybdenum, iron and titanium. Preferably the mechanical alloy comprises a multi-phase material, including at least one amorphous phase. Also, the at least two elements are preferably either nickel (from about 5 to 15 at. %) and molybdenum (from about 0.5 to 5 at. %) or iron (from about 5 to 15 at. %) and titanium (from about 5 to 15 at. %). The hydrogen storage materials are created by mechanical alloying in a milling apparatus under an inert atmosphere, such as argon, or a mixed atmosphere, such as argon and hydrogen. The speed and length of the milling are varied.
