Filed:

Mar 9, 2006

Appl. No.:

11/372405

Inventors:

Cosmin A. Corbea - Bellevue WA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

H04B 1/16

US Classification:

4551851, 4551661, 4551662, 4551861, 455 45

Abstract:

Described is a communication system including wireless client devices. In the described system, the client devices may be wrist-worn watches such as are in common use today, except that the watches are specially configured to receive transmissions from broadcast towers. A client device is associated with one or more home service regions, and is configured to receive personal messages on a home channel when in the home service region. The client device employs a self-assignment method to identify and select a home channel without the need for interaction by a user. A tower discovery method is employed to identify broadcast towers and available channels within a service region. A failover method is employed to identify a change in the broadcast system, and take appropriate action such as, for example, changing to another broadcast tower, selecting another frequency, selecting a sleep mode, as well as others.

International Classification:

H04L 12/56

US Classification:

3703954, 370437, 370458, 370462, 370474, 370498

Abstract:

Serialized data from broadcast services is provided to a broadcast server for transmitting to one or more client devices. The serialized data may correspond to shared data, private data, or control data. Data is scheduled for transmission based on weighted priorities including quality of service metrics. The transmission frame is arranged according to a frame protocol that includes provisions for a table of contents indexing system for the shared data. Packets of shared data are formatted based on criteria that is known by the particular broadcast service and corresponding application that is resident on the client device. The client device receives the table of contents at the transport layer, and notifies applications of data that will be available in the next frame. Applications submit prioritized requests to the transport layer, requesting data in the next frame. Data is retrieved by the transport layer, and deserialized by handlers for each application.

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G08G 1/00

US Classification:

701118

Abstract:

Either vehicle traffic or financial markets data is regularly broadcast in a fixed size packet over a wireless network in a push manner to one or more wireless receiver devices located within a particular service coverage region. A data center stores information specific to the particular region including drive-times strings metadata, drive-times data, drive-times route metadata, traffic incident data and financial markets indicators data. The data center decides upon a particular type of information to be placed into a payload of a next packet to be broadcast and pre-formats this information accordingly without receiving any information from the receiver devices. Data structures are provided which contain data representing the drive-times strings metadata, drive-times data, drive-times route metadata, traffic incident data and financial markets indicators data.

International Classification:

G06F 7/00
G06F 9/46

US Classification:

707793, 718102

Abstract:

The present invention provides a highly reliable and scalable architecture for data centers. Work to be performed is divided into discrete work units. The work units are maintained in a pool of work units that may be processed by any number of different servers. A server may extract an eligible work unit and attempt to process it. If the processing of the work unit succeeds, the work unit is tagged as executed and becomes ineligible for other servers. If the server fails to execute the work unit for some reason, the work unit becomes eligible again and another server may extract and execute it. A server extracts and executes work units when they have available resources. This leads to the automatic load balancing of the data center.
