    摘要: A communication system generates a Master Session Key (MSK) for accesses to a system entity that does not provide encryption to traffic. Both the home server and the user generate the same MSK. The MSK is used to generate encryption keys for traffic. In one embodiment the MSK is generated using a hashing function and information specific to the requestor. The home server determines the need to generate the MSK based on information contained in an access request message. Once generated, the MSK is provided to the system entity to enable the entity to encrypt communications.

    摘要: Method and apparatus for detection and selection of Wireless Local Area Network (WLAN) service. A remote device includes a preference database for storing selection criteria for a plurality of access media. Access medium detector(s) determine accessibility of access media, and a selector selects one of the access media based on the selection criteria. The selection criteria indicate when to switch between access media.

    摘要: Method and apparatus for dynamic provisioning of a Mobile Station (MS) to provide server configuration information. In one embodiment, a home network determines whether to use the visited local network or the home network. An indicator selecting the associated server is transmitted. The server is for session control, such as Session Initiation Protocol (SIP) control of voice over Internet Protocol (IP) communications.

    摘要: A wireless communications network (100) includes roving subscriber-stations (114) and base stations (110) receiving broadcast programs from a content server. A subscriber-station evaluates (618, 620) whether a desired program is available from a subject base station. According to this evaluation, the subscriber-station takes steps to (1) receive the desired program on a shared channel for reception by multiple subscriber-stations (816), or (2) initiate (804, 720) base station delivery (724) of the desired program to the subscriber-station on an individual channel. Responsive to a message from a subject subscriber-station identifying a desired program, a base station either (1) continues (819) transmitting the desired program upon a shared channel, (2) starts (816) transmitting the desired program on a shared channel, or (3) sends the subject subscriber-station a channel assignment message and commences transmission (722) of the desired program on the assigned individual channel.

    摘要: Method and apparatus for detection and selection of Wireless Local Area Network (WLAN) service. A cellular network may provide an advertisement for a WLAN, such as in an overhead signaling message. The advertisement may identify the Access Point(s) by an Extended Service Set Identifier (ESSID). The remote station may then scan for the WLAN service automatically or manually.

    摘要: Mobile unassisted dormant handoff in a wireless communication system supporting packet data communications. While in a dormant mode, a mobile node may change packet zones, wherein different packet zones are serviced by at least one different infrastructure element, without identifying the change to the system. The change in packet zone does not necessarily trigger establishment of a communication path for the mobile node until there is packet data ready for communication. In one embodiment, mobile assistance is adapted to the system, and is disabled at the mobile node by an indication in a system parameter message transmitted by the system and received by the mobile node.
