20090217038 | Methods and Apparatus for Locating a Device Registration Server in a Wireless Network - Methods and apparatus for locating and accessing a data server in a wireless network are disclosed. The disclosed techniques may be used to allow a wireless device provided with temporary credentials to access a wireless network and obtain a network address for a data server for downloading subscription credentials. An exemplary wireless device comprises a processing unit configured to send an access authentication request to a wireless network, and to receive an authentication challenge value from the wireless network in response. The processing unit is further configured to generate a cryptographic response from the authentication challenge value and to send the cryptographic response to the wireless network, and to also derive a data server address from the authentication challenge value. Thus, the authentication challenge value serves two purposes—as a challenge key for use in a network access authentication procedure, and as a carrier for data server address information. | 08-27-2009 |
20090217348 | Methods and Apparatus for Wireless Device Registration - Disclosed are a system and methods for associating a “generic” wireless device, i.e., a device that is not pre-programmed with subscription credentials corresponding to a particular operator, with a Home Operator designated by the device's owner. The disclosed system and methods further facilitate the automatic linking of a newly activated M2M device to an appropriate server for downloading the subscription credentials for the Home Operator. The disclosed system includes a registration server for maintaining electronic registration data for a plurality of wireless devices and for directing newly activated wireless devices to a server for downloading “permanent” subscription credentials, such as a downloadable USIM. The disclosed system further includes a subscription server for updating registration server entries to reflect an association between a first wireless device and its corresponding home network. In some embodiments, the subscription server may be further configured for downloading subscription credentials to subscribing wireless devices. | 08-27-2009 |
20090217364 | Method and Apparatus for Managing Subscription Credentials in a Wireless Communication Device - According to the teachings presented herein, a wireless communication device reverts from subscription credentials to temporary access credentials, in response to detecting an access failure. The device uses its temporary access credentials to gain temporary network access, either through a preferred network (e.g., home network) or through any one of one or more non-preferred networks (e.g., visited networks). After gaining temporary access, the device determines whether it needs new subscription credentials and, if so, uses the temporary access to obtain them. Correspondingly, in one or more embodiments, a registration server is configured to support such operations, such as by providing determination of credential validity and/or by redirecting the device to a new home operator for obtaining new subscription credentials. | 08-27-2009 |
20090253409 | Method of Authenticating Home Operator for Over-the-Air Provisioning of a Wireless Device - A method and apparatus is provided for authentication between a home network and a wireless device during device activation using a registration server as a trusted agent. The wireless device owner subscribes to the services of the home network and the home network registers as the service provider with the registration server. When the home network registers with the registration server, the registration server provides authentication data to the home network to use for authentication with the wireless device. Because the wireless device has no prior knowledge of the home network, the wireless device connects to the registration server to obtain contact information for the home network. The registration server provides home network data to the wireless device. In some embodiments, the registration server may also provide second authentication data to the wireless device for authenticating the home network. When the wireless device subsequently connects to the home network to download permanent security credentials, the home network uses the information provided by the registration server to authenticate itself to the wireless device. The authentication procedure prevents a third party from fraudulently obtaining confidential information from the home network or the wireless device. | 10-08-2009 |
20100177698 | Network Based Local Mobility Management - A network comprises a NetLMM domain having at least one Host Identity Protocol proxy coupled to one or more Access Points for communicating with a Mobile Node and acting, in use, as an Access Router for the NetLMM domain. Use of an HIP proxy as an Access Router allows the Access Router itself to be mobile. Furthermore, the Access Router can reside in IPv4 networks, and can even be behind NAT boxes located between the Access Router and a Local Mobility Anchor to which the Access Router is registered. The invention may be applied using a hierarchical architecture in which each domain comprises a respective Local Mobility Anchor coupled to each HIP proxy acting as an Access Router in the domain. The Local Mobility Anchor of a domain may itself be an HIP Local Mobility Anchor. Alternatively, the HIP proxies in a domain may be arranged in a distributed manner. | 07-15-2010 |
20110055566 | Verifying a Message in a Communication Network - A method and apparatus for verifying a request for service in a communication network. An authentication node generates a secret and transmits the secret to a node providing a service. The authentication node then receives a request for authentication from a requesting node, and once the requesting node is authenticated, the authorisation node sends an identifier for the requesting node and a first token, which is derived using the secret and the identifier. A service providing node subsequently receives a request for service from the requesting node, the request including the identifier for the requesting node and the first token. The service providing node derives a second token using the identifier and the secret. If the first token and the second token match, then the service providing node allows the request, and if the first token and the second token do not match, then the request is refused. | 03-03-2011 |
