Embodiment
Describe in detail with reference to the accompanying drawings according to one exemplary embodiment of the present invention.In accompanying drawing, by same or similar Reference numeral, give structure and the essentially identical part of function, and in order to make specification simpler and clearer, omitted about the redundancy of substantially the same part and described.
Electronic equipment in wireless network has different resources conventionally, such as showing resource (display unit, 3-D graphic accelerator module etc.), user interface resource (touch-screen, mouse etc.), computational resource (central processing unit (CPU), application-specific integrated circuit (ASIC) (ASIC) etc.) and network insertion resource (LAN access connection, the 3G with internet access capability access connection etc.).Thereby remote resource service according to the present invention can comprise long-range demonstration service, remote subscriber interface, remote computing services and telecommunication network access service.
According to the present invention, provide remote resource service to be called as ISP (Service Provider) for the electronic equipment of other electronic equipments, use the electronic equipment of the remote resource service that other electronic equipments provide to be called as service requester (Service Requester).Be understood that, in actual applications, a certain electronic equipment may be a kind of ISP of remote resource service, is again the service requester of another kind of remote resource service simultaneously.Clearer in order to make to describe, below ISP and service requester are separately described separately, this does not also mean that and limits the invention.ISP of the present invention and service requester also can be realized in identical entity.
Fig. 1 is the flow chart that the method that remote resource service is provided according to an embodiment of the invention in ISP is shown.
With reference to Fig. 1, at step S101, ISP's broadcast packet in wireless network contains the notice message of remote resource service list, so that its various remote resource services that can provide of all around service requesters to be provided.Wherein, this remote resource service list comprises at least one remote resource service identifier and corresponding remote resource service description information.
For example, suppose that this ISP provides five kinds of remote resource services, this remote resource service list is as shown in table 1 below:
Table 1
| Remote resource service identifier | Remote resource service description information |
| “SVC001” | " long-range demonstration service 1: long-range demonstration output " |
| “SVC002” | " long-range demonstration service 2: remote graphics accelerates " |
| “SVC003” | " remote user interface service 1: remote touch screen " |
| “SVC004” | " remote user interface service 2: remote mouse " |
| “SVC005” | " remote computing services: FEM (finite element) calculation " |
At step S103, ISP sets up remote resource service with at least one service requester and is connected (link).According to embodiments of the invention, provide the ISP of remote resource service to connect with a plurality of service requesters, so that remote resource service (" one-to-many ") to be provided to them simultaneously.
Fig. 2 illustrates the flow chart of setting up the process of remote resource service connection in Fig. 1 step S103 ISP.
With reference to Fig. 2, at step S201, ISP receives the remote resource service connection request from service requester, and this remote resource service request comprises the remote resource service identifier (for example " SVC002 ") that service requester is selected.
At step S203, the remote resource service that ISP identification is corresponding with being included in remote resource service identifier in remote resource service request.For example, suppose that the remote resource service identifier comprising in this remote resource service request is " SVC002 ", ISP's identification remote resource service corresponding with " SVC002 " is that remote graphics accelerates service.
At step S205, ISP determines that whether available with the remote resource of identifying if serving corresponding local resource.For example, suppose that the local resource corresponding with remote graphics service is graphics acceleration unit, this graphics acceleration unit can be accelerated service for 8 service requesters provide remote graphics.Owing to being currently connected to this ISP, use the service requester of remote graphics acceleration service to only have 3, ISP determines that this local resource (graphics acceleration unit) is available, thereby connects and reply to the service of service requester transmission remote resource at step S207.Otherwise if ISP determines that corresponding local resource is unavailable, denial of service requestor's remote resource is served connection request.
In addition, according to embodiments of the invention, ISP is setting up remote resource service while being connected with service requester, can also carry out service access control procedure (such as authentication) and service parameter-negotiation procedure, for example, service requester is issued ISP by parameters such as the operating system version of self, screen resolutions, and ISP adjusts the corresponding parameter of local resource with this.
Return with reference to Fig. 1, after setting up remote resource service connection, at step S105, ISP connects from service requester receiving remote resource service agreement input data by remote resource service.These remote resource service agreement input data are to serve corresponding standardized data with corresponding remote resource.In some applications, " remote graphics acceleration " service is for example provided, remote resource service agreement input data may be a large amount of need to be by the graph data of real-time Transmission, in order to save remote resource service, connect (link) transmission bandwidth, strengthen transmission reliability and fail safe, via this remote resource service to connect remote resource service agreement input data that (link) send to ISP can be encoded and/or encrypt after data.
At step S107, ISP is converted to local resource import of services data by the remote resource service agreement input data of reception.For example, for " long-range demonstration service ", corresponding local resource input service data can be to show data, such as picture frame (frame) etc.; For " remote user interface service ", corresponding local resource import of services data can be operating user interface instruction code and operating user interface data etc.; For " remote computing services ", corresponding local resource import of services data can be to calculate target data.
When conversion remote resource service agreement input data, ISP can be with reference to the specification of local resource.For " long-range demonstration service ", can show that the display resolution of resource changes demonstration data based on this locality.For example, suppose the resolution lower (SD) as the display unit of the local resource of " long-range demonstration service 1: long-range demonstration output ", and the resolution higher (HD) of the picture frame comprising in remote resource service agreement input data can be converted to the demonstration data of low resolution to show on display unit.These are only illustrations, the invention is not restricted to this.
In addition, for " remote user interface service ", can the operating user interface mode based on local user interface resource carry out converting users interface operation data.For example, the local resource of supposing " remote user interface service 1: remote touch screen " is touch-screen, and the operating user interface data that comprise in remote resource service agreement input data are corresponding to the mouse action of the electronic equipment of service requester, can change according to the corresponding relation of touch-screen and mouse action, for example, between the double click operation of mouse and the clicking operation of touch-screen, change.These are only illustrations, the invention is not restricted to this.
In addition, if this remote resource service agreement input data be encoded and/or encrypt after data, at step S107, also should be to carrying out again above-mentioned conversion operations after this remote resource service agreement input decoding data and/or decryption oprerations.
At step S109, the local resource service module that ISP's identification is corresponding with local resource import of services data.According to embodiments of the invention, ISP can comprise a plurality of local resource service modules corresponding with long-range demonstration service, remote user interface service, remote computing services and telecommunication network access service difference.
At step S111, ISP uses local resource to process the local resource import of services data that convert by corresponding local resource service module.For example, for " long-range demonstration service 1: long-range demonstration output ", ISP shows data on ISP's display unit by corresponding local resource service module, for " long-range demonstration service 2: remote graphics accelerates ", ISP is by corresponding local resource service module, if graphics acceleration unit is to showing data and play up and the processing such as structure, etc.
ISP is converted to remote resource service agreement output data at step S113 by the local resource service output data from local resource service module, as previously mentioned, if these remote resource service agreement output data need to be encoded and/or encrypt, at step S113, also should produce this remote resource service agreement output data to this local resource service output decoding data and/or decryption oprerations.
At step S115, ISP sends the remote resource service agreement output data of conversion to service requester.
For example, ISP is converted to remote resource service agreement output Data Concurrent at step S113 and step S115 by the demonstration data of processing through graphics acceleration unit and gives service requester.Yet, being understood that, these two steps are optional.For example, the remote resource service for such as " long-range demonstration service 1: long-range demonstration output ", does not need to service requester return data.
According to embodiments of the invention, for fear of taking for a long time because of inactive service requester the efficiency that resource affects resource service, if service requester does not send remote resource service agreement input data in the given time, ISP disconnects and being connected with the remote resource service of this service requester, and discharges relevant local resource.
In the above-described embodiment, the remote resource service that ISP provides can comprise long-range demonstration service, remote user interface service, remote computing services and/or telecommunication network access service.These are only illustrations, the invention is not restricted to this.
