The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Shown in Figure 1 is individual network service system schematic.Personal network equipment and individual net gateway adopt in-plant on-link mode (OLM) to constitute individual net or are referred to as PAN (Personal Area Network).Individual's net gateway can be a mobile communication terminal, also can be the cable gateway (as computer, digital home gateway, set-top box etc.) that the extranet access ability is arranged.Personal network equipment obtains the corresponding business content by service suppliers such as individual net gateway access service server or application/content server.What the present invention considered is exactly the transmission bandwidth resource that how to effectively utilize when personal network equipment obtains a kind of business tine simultaneously between service supplier and the individual net gateway.For example, when personal network equipment A, B, C will download same video frequency program, the present invention realizes this demand with regard to the ability that has made full use of each equipment in the individual net.
Usually, personal network equipment A, B, C initiatively initiate the request of video frequency program download business (if individual net gateway itself is also asked this business, also can regard people's net equipment one by one as), individual's net gateway is directly transmitted these service request and is given service supplier, service supplier sends to individual net gateway respectively according to the adaptive suitable content of the ability of different personal network equipments respectively, and individual net gateway is distributed to each personal network equipment again.The screen size difference of personal network equipment A, B, C for example, the content that sends respectively of service supplier is exactly that image varies in size so.But we can think that this is the different editions of same business tine.Thinking of the present invention is that different personal network equipments are when initiating the service request of same business tine simultaneously, individual's net gateway is not directly transmitted these service request, but only send a service request, the business tine that service supplier is just sent a version gets final product, and improves the transmission bandwidth service efficiency to reach.Individual's net gateway directly is distributed to corresponding personal network equipment with the business tine of this version or carries out being distributed to corresponding personal network equipment after the content conversion.And the business tine of this version is some in the personal network equipment of directly adaptive a plurality of requested services, that is to say that service supplier only needs the device parameter of adaptive one of them representative equipment.The selection course of this representation parameter can be carried out by individual net gateway, is perhaps carried out by service supplier.Wherein, the gateway of individual's net can be a mobile communication terminal.
Fig. 2 is the flow chart that obtains the method for business tine according to the personal network equipment of first embodiment of the invention.May further comprise the steps:
Step S20.Personal network equipment sends to individual net gateway with the device parameter (information such as screen size, content format) of described equipment;
In this step, the equipment in the individual net obtains business tine if desired, then the device parameter of its equipment (as the content format of screen resolution, support, CPU disposal ability, operating system, running environment etc.) is sent to individual net gateway.Device parameter is meant when obtaining business tine, and the call parameter that carries out content adaptation that service supplier is required is as screen size, resolution, content format, device processes ability, operating system, running environment etc.Here individual net gateway is the equipment of visit outer net, as mobile communication terminal, home gateway, set-top box etc.
Step S22.Described individual net gateway sends to service supplier together with the device parameter of a plurality of personal network equipments;
In order to obtain the business tine adaptive with the personal network equipment ability, device parameter sends to long-range service supplier by individual net gateway, provides the equipment of business tine as service server or application/content server or other.
Step S24.Service supplier is selected a representation parameter from described a plurality of device parameters, and will send to individual net gateway with a kind of content of this parameter adaptation;
Here from a plurality of device parameters, select a representation parameter, its requirement is that the content according to this parameter adaptation satisfies the requirement that has the equipment of peak performance among the personal network equipment of requested service, and/or according to the content of this parameter adaptation after through the content conversion can be adaptive remaining asked should business personal network equipment.Therefore the service supplier content that only sends a kind of version to be saving bandwidth, and direct certain equipment (being assumed to be device A) of adaptive above-mentioned personal network equipment of this content, and this content can be through adaptive other personal network equipment after the conversion further.
In the embodiment of another one, the selection of representation parameter is that the minimum requirements that the content according to this parameter adaptation satisfies the personal network equipment ability is carried out, and can reach minimum bandwidth by the adaptive content of this device parameter in transmission and take.Perhaps the selection of representation parameter is the device parameter that has the ability of equalization in these equipment of selection.
In another embodiment, if in step S22, individual net gateway has been selected suitable a kind of parameter (being assumed to be the parameter of device A), only this parameter is sent to service supplier.Then in step S24, service supplier just need not to do to have selected the work of parameter, sends to individual net gateway after a kind of parameter adaptation content that only needs to send by individual net gateway.
Step S26.After individual's net gateway receives foregoing, be distributed to corresponding personal network equipment or carry out being distributed to personal network equipment after the content conversion.
For example the representation parameter of selecting among the above-mentioned steps S24 is the parameter of device A, and the content that then individual net gateway receives can directly send device A to.Carry out sending to relevant device after the suitable content conversion according to the parameter of all the other equipment then.
