Abstract:
Methods and apparatus are provided for facilitating mobility of a mobile station (MS) in a wireless local area network (WLAN) with uninterrupted communications. The method includes associating (501) a MNIP address (410) with the MS; establishing (502) a communications link between the MS and a first WLAN AP (109) in a first subnet (117) and associating (503) a first WLAN IP (420) address with the MS. Then using (505) the first WLAN IP address for an application that benefits from a persistent connection. Further included is establishing (507) a second communications link between the MS and a second WLAN AP 111 in a second subnet (119). When the MS is using the application, continuing to use the first WLAN IP address for communicating with the second subnet; and requesting (517) a second WLAN IP address in the second subnet when the persistent connection is no longer needed.
Abstract:
A method, information processing system, and wireless device provide authentication information to a network. The method includes determining that at least one authentication context (120) resides in memory (412). The at least one authentication context (120) is analyzed to determine if at least one realm identifier associated with a home service provider is included in the at least one authentication context (120). A user is prompted to update the at least one authentication context (120) with at least one realm identifier associated with a home service provider in response to determining that at least one realm identifier fails to be included in the at least one authentication context (120). At least one realm identifier is received (612) from a user that is associated with a home service provider. The at least one authentication context (120) is updated with the at least one realm identifier received from the user.
Abstract:
A method and apparatus for providing a service from an application service provider to a client in a communications system including a network proxy describes a first step of defining services provided by the service provider as Extensible Markup Language (XML) metadata. A next step includes defining services desired by the client as XML metadata. A next step includes collecting the XML metadata from the client and service provider. A next step includes comparing the client XML metadata against the service provider XML metadata. A next step includes providing the substantially matched service from the service provider to the client upon the finding of a substantial match between the client metadata and the service provider metadata.
Abstract:
A Session Initiation Protocol (SIP)-compliant proxy (106) receives a first INVITE message destined for a mobile station (102). The first INVITE message is associated with an initial Internet Protocol (IP) contact address for the mobile station (102). Subsequently, it is determined whether an IP address update for the mobile station (102) may have occurred and a new IP contact address is obtained for the mobile station (102). A second INVITE message is sent to the mobile station (102) at the new contact address so as to continue a session initiation.
Abstract:
A device (101) is informed by a device manager (131) that it is being hotlined and is provided certain hotlining state information. This information may enable devices with different types of user interfaces (browsers, automated clients, handsets, etc.) to trigger an appropriate application and begin communicating with an appropriate network location (in a secure and controlled fashion) to resolve the hotlining issue. The hotlining state information may also enable the device to access network services, while hotlined, such as emergency services. Assuming that a resolution to the hotlining is attained, the device may then be notified that hotlining has terminated. The device may then resume its access to regular network services, perhaps as gracefully as re-entering one or more data sessions interrupted by the hotlining.
Abstract:
A communication system provides in-band speaker arbitration in a multi-participant communication session by use of RTP floor control messages that include a speaker arbitration command embedded in a data packet header extension.
