    摘要: Inter-Working Function (IWF) for interfacing between a Wireless Local Area Network (WLAN) and a communication system. The IWF may contain sufficient information to authenticate a user access to the WLAN, or the IWF may need to request authentication from the communication system. In one embodiment, the IWF sends an access challenge to the WLAN for a user. The IWF may then pass a response to the challenge on to the communication system for authentication. The IWF allows the WLAN to use the authentication capability of the communication system for local authentication.

    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: 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.
