Ian Leslie Sayers - Redwood City CA
Paul Jan Long - San Francisco CA
Sheausong Yang - Saratoga CA

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04B 138

US Classification:

455555, 455461, 455554

Abstract:

A communication system formed by a private network that includes a private wireless network. The communication system includes a public wireless network using a public wireless protocol, such as GSM, and includes public networks, such as PSTN, ISDN and the Internet, using a wired protocol, such as IP. The private network also includes a local area network (LAN) and the private network connects to the public networks using a wired packet protocol, such as IP. The public and private wireless networks operate with the same public wireless protocol, such as GSM, and the private wireless network additionally operates with a wired packet protocol, such as IP. The communication system permits users to operate freely in both public and private wireless networks using standard mobile stations while achieving high private network data rates. The communication system uses normal wireless handsets or other mobile or fixed stations without need for any modifications.

International Classification:

H04B 701

US Classification:

455502, 455422, 455507, 370350, 370503

Abstract:

A communications system extends over a cellular region formed of a plurality of wireless cells where each cell covers a portion of the cellular region. Each cell has a base station clock unit that facilitates reliable and accurate synchronization with other clocks units in other cells using a master clock signal from a global positioning system (GPS) or other accurate frequency source. The clock unit in each cell includes a local clock providing a local clock signal for clocking the cell. A master clock source provides one or more master clock signals and a clock synchronizer receives the master clock signals and forms a synchronizing master clock signal for synchronizing the local clock signal. In one or more of the wireless cells of the communication system, the clock unit is a master clock unit which includes a clock distributor for distributing a distributed master clock signal to one or more other wireless cells having slave clock units.

International Classification:

H04L 1266

US Classification:

370356, 370466

Abstract:

A communications system extends over a cellular region formed of a plurality of wireless cells where each cell covers a portion of the cellular region. Each cell has a base station which is responsible for communication with the cellular subscriber. In order for a call to be properly managed in the public cellular domain, responsibility for call handling and processing must first be managed by a public MSC. Call handling with the public MSC for a private cellular subscriber first requires the exchange of information between the two systems. This is facilitated through the exchange of MAP and A interface signaling between the private and public cellular systems. Since this information on the private network is normally transmitted via IP, this information must be converted to standard SS7 based MAP and A protocol signaling in order for the public MSC to process.

US Classification:

445446, 455443, 455444

Abstract:

A communications system extending over a cellular region and formed of a plurality of wireless cells. The communications system extends over a cellular region formed of a plurality of wireless cells. Each cell covers an area which includes a portion of the cellular region. Each particular cell includes a base station having a transmitter for transmitting a particular cell signal having parameters including a transmitting frequency and a transmitting power. The particular cell signal is transmitted to cover a portion of the cell region. Each of the base stations includes a parameter detector for detecting the other parameters of the other cell signals from the other cells in the cellular region. A parameter controller controls the particular parameters for the particular cell. The parameters for the particular cell are based upon the other parameters for the other cell signals so that the particular cell signal does not interfere with the other cell signals in the cellular region.

Abstract:

A communication system formed by a private wireless network that can be used with public wireless networks using a public wireless protocol, such as GSM, and typically includes public networks, such as PSTN, ISDN and the Internet, using a wired-packet protocol, such as IP. The private network also typically includes a local area network (LAN) and the private network typically connects to the public networks using the wired-packet protocol, such as IP. The public and private wireless networks operate with the same public wireless protocol, such as GSM, and the private wireless network additionally operates with the wired-packet protocol, such as IP. In this environment, multiple wireless cells are present and inter-cell handovers employ multiple protocols including the wired-packet protocol.

Abstract:

A method and apparatus is provided in which a digital image is transmitted to a presentation projector resource over a wireless transmission medium using a reduced amount of transmission bandwidth by transmitting a subset of the digital image data. The subset image data may be a delta subset that represents those areas of the image that have changed since the previous transmission. The subset image data may also be a scalable vector graphics representation of the subset of the digital image. Header data is provided to further describe the subset image data. A projector discovery logic selects a suitable projector resource based on the order or signal strength of the discovery replies. A wireless image transmission session is established with the selected projector resource during which the projector is unavailable to other devices. The subset image data may be compressed and transmission coordinated with the projector resource so that the data is sent only when it is ready to be received. A wireless to digital visual interface (DVI) graphics engine decompresses and renders the image for output to a DVI connector receptacle.
