  • Publication number: 20060045080
    Abstract: Methods are provided for transitioning between SIP and MIP. Mobile devices, upon detecting a new system, automatically attempt a MIP session to avoid the default position of SIP. A history is maintained of systems visited, and for systems that did not support MIP in the past, a MIP session is not attempted, but rather SIP is initiated from the start.

  • Publication number: 20060002397
    Abstract: One illustrative method of controlling wireless network resources for data sessions involves the steps of identifying IP address usage for mobile stations operating in a wireless communication network and causing a data inactivity timer of a data session for a mobile station to be set to an initial value that depends on the IP address usage. The data inactivity timer is set to a relatively large value when the IP address usage is low, but to a relatively small value when the IP address usage is high in order to expeditiously release underutilized network resources. The data session may be Point-to-Point Protocol (PPP) session for which an IP address is dynamically-assigned to the mobile station.

  • Publication number: 20050201382
    Abstract: Methods and apparatus for the communication of network capability information are described. When a mobile station is engaged in a call, an in-traffic channel message is transmitted from a base station of a wireless communication network to the mobile station. The message includes information indicative of whether the network supports a predetermined concurrent service or feature. The predetermined concurrent service or feature may be a mobile-requested Quality of Service (QoS) parameter usage feature or a mobile-initiated position location determination feature. The in-traffic channel message may be an in-traffic system parameter message, a general handoff direction message, or a universal handoff direction message, as examples. Preferably, the network is a cdma2000-type network. Since the mobile station is made aware of such information, more efficient operation may be realized.

  • Publication number: 20050192039
    Abstract: The present invention provides methods, systems, and devices for selective override of do-not-disturb in a wireless communications network, in which a user is provided with the option to query and modify the ignoring of do-not-disturb (DnD) for certain reasons. In some embodiments, DnD is ignored when an incoming call is an urgent call. In other embodiments DnD is ignored when an incoming call is an emergency call. In some embodiments a call processing server manages and performs selective override of do-not-disturb in an OMA compatible system. In yet other embodiments, a mobile device is adapted to send to a dispatch network a request to query or set an ignoreDnD flag, along with associated ignoreDnD reasons.

  • Publication number: 20050174939
    Abstract: Methods and apparatus for controlling wireless network operations associated with a flow control process which terminates data communications to a mobile station based on an out-of-coverage condition between the mobile station and a wireless communication network. In the wireless communication network, an indication is identified which indicates whether a mobile station utilizes an always-on connection for a data service. Based on the indication indicating that the mobile station utilizes the always-on connection, the flow control process is bypassed. Otherwise, the flow control process is performed. The always-on connection may be utilized for an e-mail application for the mobile station and involve a Point-to-Point Protocol (PPP) session.

  • Publication number: 20050165944
    Abstract: In accordance with the teachings described herein, systems and methods are provided for always-on wireless IP communication. An access provider network (APN) that includes an always-on packet data serving node (PDSN) may be used to communicate over a wireless communication link with a mobile station. The PDSN may include an inactivity timer and may be used to set the inactivity timer to an inactivity timer starting value and send a starting value estimate to the mobile station over the wireless communication link, wherein the starting value estimate is a function of the inactivity timer starting value. The mobile station may include an inactivity timer estimate and may be used to receive the starting value estimate and set the inactivity timer estimate to the starting value estimate. The mobile station may also be used to reset the inactivity timer estimate to the starting value estimate when the mobile station communicates with the APN.

  • Publication number: 20050153691
    Abstract: A method and system of providing a mobile data device in a wireless system with information about preferred networks to connect to, the mobile data device having a preferred roaming list with a list of networks, the method comprising the steps of: adding to the preferred roaming list information about whether each network in the list of networks supports third generation data capabilities; and determining preferred networks based on information within the preferred roaming list including a geographic area and whether the network supports third generation data capabilities, whereby, within the geographic area, the mobile data device prefers networks which support third generation data capabilities over networks which do not support said third generation data capabilities. Other information that may be added to the preferred roaming list includes whether the network supports data roaming, Mobile IP services or always-on features.

  • Publication number: 20050078638
    Abstract: A method and apparatus for reverse and forward link dynamic packet transport to and from a wireless data device in a CDMA2000 network, the method comprising the steps of: determining a frame transport capability of a reverse access channel or a forward common channel; checking whether a data packet falls within the frame transport capability; and if the data packet falls within the frame transport capability encapsulating the data packet as a data burst message; sending the data burst message over the reverse access channel or forward common channel; receiving the data burst message; and reforming the data packet.

  • Patent number: 6106773
    Abstract: The present invention is directed to pathogen inactivating compositions that can be used to disinfect various biological fluids, such as blood, blood fractions, and the like. The compositions are suitable for disinfecting biological fluids containing valuable, but labile, components such as proteins without destroying the desired properties of such components. The pathogen inactivating compositions of the present invention are produced by contacting water or an aqueous solution with iodinated matrix material. The compositions can be pre-formulated and stored for subsequent use in disinfecting a wide range of biological fluids.
