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 method and apparatus are provided for managing radio access point (RAP) devices and enterprise controller devices in a wireless communication network. An enterprise controller device registers with a gateway device, and the enterprise controller device receives a registration request from multiple RAP devices that are serviced by the enterprise controller device. As the RAP devices register with the enterprise controller device, the enterprise controller device generates a list of the RAP devices registered with the enterprise controller. As the enterprise controller receives additional registration requests from additional RAP devices, the enterprise controller updates the list. The enterprise controller sends the list to the gateway device with which it registers so that the gateway device is aware of RAP devices serviced by the enterprise controller device. In this way, aggregated messages may be sent from the gateway device to the enterprise controller.
Abstract:
Techniques are provided to allow more than a fixed number of radio access point devices to be deployed within a macro cell. At a controller apparatus, a registration request is received from a radio access point device configured to operate in a wireless network to serve one or more wireless client devices in the wireless network in respective relatively small coverage areas. The registration request comprises a macro cell identifier associated with a macro cell base station configured to operate in the wireless network to serve one or more wireless client devices in a relatively large coverage area, a radio access point cell identifier associated with the radio access point device, and a particular primary scrambling code selected for use by the radio access point device. When the particular primary scrambling code is not available for use, methods are provided to allocate it in a shared manner but without degrading handover service.

Abstract:
Methods and systems for providing access class based picocell policy enforcement includes determining whether user equipment registered with a radio access point is known to an enterprise other than a macro telecommunications service provider and eligible for differentiated services, recovering an internet protocol (IP) address associated with communication traffic from the user equipment, confirming that the IP address associated with communication traffic from the user equipment is within a predetermined range, determining whether the IP address associated with communication traffic from the user equipment uniquely identifies an enterprise context, as opposed to a macro telecommunications service context, and when the IP address associated with communication traffic from the user equipment uniquely identifies an enterprise context, causing IP packets received from the Internet to be routed to an enterprise controller that services the user equipment via the radio access point.
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:
Systems and methods for providing identity management and mobility management are disclosed. The management scheme provides mobility in multi-device and multi-homed deployments. A collection of three identities, a device identity, a link layer identity, and a user identity, can be used to provide mobility for a number of devices under different use scenarios. In one embodiment, a method is disclosed for receiving messages from a mobile device at a mobility gateway, the messages including identifiers such as a user identifier, a link layer identifier, and a device identifier where identifiers are stored or retained at the mobility gateway. When a subsequent network attach request is received including one or more identifiers, a reconnection can occur, based on a result of comparing the stored identifiers with the received one or more identifiers.
Abstract:
Techniques are provided for transmitting and receiving communications on behalf of wireless user equipment devices between a plurality of radio access point (RAP) devices and a gateway apparatus through a controller apparatus. A controller apparatus generates a plurality of first identifiers used for communications on behalf of corresponding wireless user devices between the controller apparatus and respective RAPs. Each first identifier identifies a wireless user device and a RAP to which the wireless user device is associated. The controller apparatus maps each first identifier to a corresponding one of a plurality of second identifiers for communications exchanged on behalf of the wireless user devices between the controller apparatus and a gateway apparatus in the wireless cellular communication network. The controller apparatus remaps a new first identifier to an existing second identifier when a particular wireless user device has handed over from a first RAP to a second RAP.
Abstract:
Techniques are provided for coordinated neighbor discovery in a wireless network served by radio access point devices that provide service in relatively small coverage areas in the wireless network. A controller apparatus sends to radio access point devices, data identifying a group of radio access point devices to which each radio access point device is assigned. The controller apparatus sends coordinating data for a neighbor discovery session during which a particular radio access point device in the group is configured to transmit a signal at maximum power during a time interval while all other radio access point devices in the group are configured to attempt to receive the signal, and to repeat the same during other time intervals during the neighbor discovery session when a different particular radio access point is configured to transmit a signal at maximum power until all of the radio access point devices in a group have transmitted. Each radio access point device generates discovery results data for signals received from one or more other radio access point devices during the neighbor discovery session. A neighbor list is generated for each radio access point device based on the discovery results. The neighbor list comprises a list of identifiers of radio access point devices that are candidates for handover of service.
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.
