Abstract: A method of providing a cordless extension system for a plurality of communication devices in a defined environment, the method comprising the steps of: detecting that a first communication device of the plurality of communication devices is placing a call in the defined environment (205); in response to detecting, automatically creating a conference bridge involving all of the plurality of communication devices, wherein the first communication device is placed in an active mode, and wherein a second communication device of the plurality of communication devices that is on-hook is placed in a dormant mode (210). The invention proposes to include a Call Agent (CA) (600) that is configured to provide a cordless extension for the plurality of communication devices in a defined environment.

Abstract: A communication device (400) responds to detecting a likely streaming content downloading event by dynamically determining (102) an amount of the streaming content to locally pre-cache prior to detecting an instruction (105) to download the streaming content and to then pre-cache (104) that amount. This determination can be based (201) on a likely period of delay between detecting the instruction to download the streaming content and being able to being providing the streaming content to a user of the communication device. If desired, this determination can further be based (202) upon a potentially less favorable period of delay. In the latter case, if desired, the pre-cached streaming content as corresponds to a period of time between the likely period of delay and the less favorable period of delay can have an intentionally reduced quality as compared to the pre-cached streaming content as corresponds to the likely period of delay.

Abstract: A method and a system for live broadcast of digital content to a user switching between one or more electronic devices are provided. Each electronic device is connected to a network. The user makes a request to switch the live broadcast of the digital content from a first electronic device to one or more electronic devices in the network. The live broadcast of the digital content on the first electronic device is suspended based on the request from the user. The first electronic device informs at least one electronic device in the network to pre-emptively store the live broadcast of the digital content. The live broadcast of the digital content is then resumed on the one or more electronic devices, based on another request from the user.

Abstract: Methods and apparatus are provided for modulating ACK/NACK persistence to improve data traffic performance. In one implementation, a method for control of automatic repeat requests between a transmitting terminal (102) and a receiving terminal (104) comprises: defining (1404) a buffer window of a buffer, the window to buffer multiple higher layer data blocks each segmented into multiple physical layer data blocks, the window beginning at a current higher layer block in which at least one physical layer block has not been received; obtaining (1406) an indication of whether physical layer blocks are completely received; determining (1408), based on the obtaining step, that a subsequent higher layer block within the window has been completely received; and discarding (1410) the current higher layer block when a time delay of the current higher layer block exceeds an estimate of a delay tolerance corresponding to a higher layer application.

Abstract: A method and apparatus for a mobile device (104) to register with a private home agent (106), the method comprising the steps: generating (304) and sending (306) a registration request (700) addressed in the public network (110) to a public address of the private home agent, the request (700) adapted to initiate registration of the mobile device with the private home agent. The mobile device is located within a public network, but belongs to a private network (102) and has a private address. The private home agent is located in the private network and has both a private address and a public address. The request also indicates that the mobile device is in the public network. In preferred form, the request includes an extension (704) that provides this indication. The home agent receives and processes the request, then forwards an appropriate reply (800) back to the mobile device.

Abstract: A system (100) for authentication in a wireless local area network (WLAN) includes a CDMA2000 authentication center (190) for authenticating CDMA2000 credentials (110), a WLAN authentication server (150) for using the CDMA2000 credentials to authenticate WLAN devices holding CDMA2000 credentials, and at least one WLAN device (130) holding CDMA2000 credentials. The WLAN server (150) performs a CDMA2000 global challenge and response (213) and a CDMA2000 unique challenge and response (223) with a WLAN device to obtain a CDMA2000 encryption key (233). The WLAN server (150) derives a master key from the CDMA2000 encryption key (234) and uses the master key to perform a WLAN challenge and response (237) with the WLAN device (130) and then derives session keys from the master key (240). The session keys protect communications between the WLAN access point (140) and the WLAN device (130).

Abstract: A wireless local area network (WLAN) communication system that includes an access point in communication with a mobile station and at least one Authentication, Authorization, and Accounting (AAA) server provides an authentication process whereby a user of the mobile station may select a WLAN service provider from among one or more WLAN service providers and/or one or more 3GPP service providers before being authenticated and further to make a decision to subscribe to the services of the selected service provider based on network service information, other than or in addition to an Service Set Identifier (SSID), associated with the selected service provider.

Abstract: Rate assignment circuitry (102) detects when a data transmission begins and originally assigns an Orthogonal Variable Spreading Factor (OVSF) code corresponding to low data rate. Over time, a base station controller (101) determines when an OVSF code and/or a repetition rate should be changed (i.e., data rate increased or decreased). The OVSF code and/or the repetition rate is changed in order to gradually increase the data rate, up to a maximum allowable data rate. Once data transmission ceases for a period of time the OVSF code and/or the repetition rate is changed in order to gradually decrease the data rate, down to a lowest allowable data rate.
