Turning now to
Also included in the server 200 is random access memory 206, suitably formed of dynamic random access memory, static random access memory, or any other suitable, addressable memory system. Random access memory provides a storage area for data instructions associated with applications and data handling accomplished by the processor 202.
A storage interface 208 suitably provides a mechanism for volatile, bulk or long term storage of data associated with the server 200. The storage interface 208 suitably uses bulk storage, such as any suitable addressable or serial storage, such as a disk, optical, tape drive and the like as shown as 216, as well as any suitable storage medium as will be appreciated by one of ordinary skill in the art.
A network interface subsystem 210 suitably routes input and output from an associated network allowing the server 200 to communicate to other devices. The network interface subsystem 210 suitably interfaces with one or more connections with external devices to the server 200. By way of example, illustrated is at least one network interface card 214 for data communication with fixed or wired networks, such as Ethernet, token ring, and the like, and a wireless interface 218, suitably adapted for wireless communication via means such as WiFi, WiMax, wireless modem, cellular network, or any suitable wireless communication system. It is to be appreciated however, that the network interface subsystem suitably utilizes any physical or non-physical data transfer layer or protocol layer as will be appreciated by one of ordinary skill in the art. In the illustration, the network interface 214 is interconnected for data interchange via a physical network 220, suitably comprised of a local area network, wide area network, or a combination thereof.
Data communication between the processor 202, read only memory 204, random access memory 206, storage interface 208 and the network subsystem 210 is suitably accomplished via a bus data transfer mechanism, such as illustrated by bus 212.
Suitable executable instructions on the server 200 facilitate communication with a plurality of external devices, such as workstations, document processing devices, other servers, or the like. While, in operation, a typical server operates autonomously, it is to be appreciated that direct control by a local user is sometimes desirable, and is suitably accomplished via an optional input/output interface 222 as will be appreciated by one of ordinary skill in the art.
In operation, feature identification data representing at least one of a plurality of available services requested from each of a plurality of data processing devices is first received. Instructions corresponding to each of the plurality of available services is then stored. The feature identification data is then tested so as to determine whether the feature is available locally. The instructions associated with each received feature identification data are then processed so as to complete a service corresponding thereto. An associated repository is then accessed when the result of the testing indicates that the feature is not available locally. Thereafter, result data associated with each requested service is then communicated to the data processing device associated with the service request.
In accordance with one example embodiment of the subject application, a server 104 or other suitable device receives data corresponding to services available to a variety of data processing devices, e.g., the document processing device 108, the cellular phone 116, the personal data assistant 118, the electronic mail appliance 120, and the like. The skilled artisan will appreciate that each of the aforementioned data processing devices 108, 116-120, correspond to functionally constrained devices. That is, each of the devices contains limited data processing capabilities. In accordance with one embodiment of the subject application, suitable available services include, for example and without limitation, data retrieval from the Internet, data storage, data processing, image processing, information retrieval, document processing, or the like.
The server 104 then receives instructions corresponding to each available service. The skilled artisan will appreciate that such instructions represent applications to be invoked, data to be generated, operations to be completed to perform a particular service, and the like. The server 104 then stores the received service data and the corresponding instructions in an associated data storage device 106. Preferably, the stored data is thereafter accessible by the server 104 for use in the locating and performance of services requested from the functionally constrained data processing devices 108, 116, 118, and 120.
Upon receipt of a service request from a data processing device 108, 116, 118, 120, or the like, the server 104 or other suitable host device, then determines the feature identification representing the received service request. That is, the server 104 identifies the service needed or requested based upon the feature or features specified in the request received from the data processing device 108, 116, 118, or 120. The received feature identification data is then tested by the server 104 so as to determine whether or not the service specified by the identification data is a locally available service, e.g., one that the server 104 is capable of performing without access to external services, devices, or the like. When the server 104 determines that it is not capable of performing the service locally, or when the requested service is specifically referenced as an external service, e.g., an Internet search, the server 104 accesses the service via the Internet 102. For example, the electronic mail appliance 120 desires to perform a web search using a suitable search engine, e.g., GOOGLE, YAHOO, or the like, the server 104 accesses the appropriate engine via the Internet 102 to retrieve results in accordance with the request from the device 120.
The server 104 then determines, based upon the data processing device 108, 116, 118, or 120, which requested the service, whether the resulting data from the externally performed service must be formatted so as to render the data understandable by the respective device 108, 116, 118, or 120. When the result data is not currently understandable by the device 108, 116, 118, or 120, the server 104 determines, based upon the device, the appropriate format to which the result data is to be converted. The server 104 then converts the data into the format determined to be understandable by the device 108, 116, 118, or 120 associated with the service request. Thereafter, the server 104 communicates the reformatted result data to the requesting device 108, 116, 118, or 120 over the respective communications links 122, 124, 126, or 128.
In the event that the server 104 determines, based upon the feature identification data, that the requested service is locally available, e.g., the server 104 is capable of performing the service without the need to access any external sources, the server 104 retrieves the instructions from the data storage device 106 corresponding to the selected service. Thereafter, the server 104 processes the instructions so as to complete the requested service. The server 104 then determines, based upon the resulting data from the service and the device type, whether the data must first be converted to a format compatible with the requesting device 108, 116, 118, or 120. When formatting is not required, e.g., the device 108, 116, 118, or 120 is capable of understanding the result data without reformatting, the server 104 communicates the data to the requesting device 108, 116, 118, or 120. When formatting is required, the server 104 retrieves the appropriate format type associated with the requesting device 108, 116, 118, or 120 from the data storage device 106 and converts the result data into the specified format. Thereafter, the server 104 communicates the data to the requesting device 108, 116, 118, or 120 via the respective communications links 122, 124, 126, or 128.
The skilled artisan will appreciate that the subject system 100 and components described above with respect to
The server 104 then tests, at step 306, the feature identification data received from the data processing device 108, 116, 118, or 120, to determine local availability of the service associated with the feature identification data. Stated another way, the server 104 determines, based upon the type of service requested by the device 108, 116, 118, or 120, whether the server 104 is capable of locally performing the service, e.g., the service does not require the server 104 to access the Internet 102 to complete the service. Examples of such services capable of being performed locally include, without limitation, data retrieval from storage 106, image processing, data storage, document processing, and the like. At step 308, the server 104 processes the stored instructions corresponding to the requested service to generate result data. The server 104, at step 310, accesses a data repository, e.g., the Internet 102, when it is determined that the service is not locally available. The skilled artisan will appreciate that step 310 corresponds to the server 104 accessing the Internet, performing or procuring the request service, and thereby generating result data representing the completed operation. Thereafter, at step 312, the server 104 communicates the result data to the requesting device 108, 116, 118, or 120.
Referring now to
At step 408, the server 104 receives a service request from an associated data processing device, e.g., the document processing device 108, the cellular telephone 116, the personal data assistant device 118, the electronic mail appliance 120, or the like. The server 104, at step 410, then determines the feature identification representing the requested service from the service request. In accordance with one embodiment of the subject application, the service request includes feature identification data representative of the desired service. Preferably, the feature identification data is capable of being interpreted by the server 104 so as to facilitate a determination of the specific service being requested. The received feature identification data is then tested by the server 104 at step 412 to determine, at step 414, whether the service is capable of being performed locally, i.e., by the server 104 without accessing the Internet 102. When the server 104 determines, at step 414, that the requested service, as identified by the feature identification data, is not locally available, flow proceeds to step 416, whereupon the server 104 accesses the requested service via the Internet 102. Result data is then received from the Internet service at step 418 and flow progresses to step 422, discussed in greater detail below.
When it is determined by the server 104 at step 414 that the requested service is locally available, flow proceeds to step 420, whereupon the server 104 retrieves the instructions associated with the requested service from the data storage device 106 and processes the instructions to complete the service, thereby generating appropriate result data. A determination is then made at step 422 whether the result data must first be converted to a format understandable by the requesting device 108, 116, 118, or 120. That is, the server 104 compares the received result data format to the formats that are understandable by the requesting device 108, 116, 118, or 120. When the result data is understandable in its current form, flow proceeds to step 428, whereupon the server 104 communicates the result data to the device 108, 116, 118, or 120 that requested the service.
When the server 104 determines at step 422 that the result data must first be converted prior to transmission to the requesting device 108, 116, 118, or 120, flow proceeds to step 424, whereupon the server 104 determines the format properties of the targeted data processing device 108, 116, 118, or 120. The result data is then formatted by the server 104 at step 426. Thereafter, at step 428, the server 104 communicates the formatted result data to the data processing device 108, 116, 118, or 120 associated with the service request.
