Virtual machine migration using 3GPP MCIM

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 authorization 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.

Verifying a message in a communication network

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.

Method and apparatus for managing subscription credentials in a wireless communication device

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.
