20140289377 | CONFIGURING NETWORK STORAGE SYSTEM OVER A NETWORK - Network storage system configuration via a network is disclosed. An IP assignment component is configured to listen for IP assignment requests over the network. Responsive to identifying an IP assignment request originating from a network storage system, the IP assignment component assigns an IP address to the network storage system, and provides configuration access to the network storage system based upon the IP address. A network device management component is configured to send identification requests over the network. Responsive to receiving a response from a network storage system having a previously assigned IP address, the network device management component provides configuration access to the network storage system based upon the previously assigned IP address. In this manner, a network storage system is (e.g., remotely) configured (e.g., over a network), rather than a technician having to physically connect (e.g., via a serial cable) to the network storage system. | 09-25-2014 |
20150081853 | NETWORK ADDRESS ASSIGNMENT WITH DUPLICATION DETECTION - Network storage system configuration via a network is disclosed. A network address assignment component is configured to listen for network discovery requests over the network. Responsive to receiving a network discovery request from a network storage system, one or more candidate network addresses are (e.g., randomly) generated until an available candidate network address is generated. For example, if a first candidate network address is determined as available (e.g., not used by another device within the network), then the first candidate network address is offered and/or assigned to the network storage system as an initial configuration network address that may be used to provide configuration access to the network storage system, otherwise a second candidate network address is generated and/or evaluated for availability. As such, configuration access may be provided over the network to the network storage system regardless of whether the network comprises an IP address assigning (e.g., DHCP) server. | 03-19-2015 |

20100173628 | SYSTEM AND METHOD FOR SELECTION OF A CELLULAR NETWORK - A system and method in a wireless communication device for receiving a System Identification Number (SID) from multiple wireless carriers operating within communication range of the wireless communication device, determining a signal quality level associated with each of the wireless carriers, determining a preference level for each of the wireless carriers based on a Preferred Roaming List (PRL), and selecting one of the wireless carriers based on the signal quality level of each wireless carrier and based further on the preference level for each wireless carrier. | 07-08-2010 |
20150111529 | PAIR-THE-PLAN SYSTEM FOR DEVICES AND METHOD OF USE - A method and system are disclosed for connecting a device to subscriptions and cellular billing plans of separate users and for managing the concurrent use of the device by the separate users. A computer-implemented method comprises enrolling a device in a cellular subscription and billing plan of a user. The enrollment includes providing an identifier for the device to a cellular subscription, effectively adding the device to the cellular subscription and billing plan selected by the user. The method and system allows the user to use capabilities of the device as governed by the cellular subscription and an associated billing plan as selected by that user, while the device is also available for use by another user via another cellular billing plan, as selected by that user. | 04-23-2015 |
