Description
Technical field
The present invention relates to the communication technology, more specifically, relate to a kind of changing method and equipment, in particular for multi-screen professional method for switching network and equipment.
Background technology
Along with the developing rapidly and popularizing of the communication technology, at present, the multi-screen business has obtained concern and application more and more widely.The multi-screen business realizing various communication services (especially content of multimedia) are offered multiple terminal equipment, for example television set, PC, hand-portable terminal, thus provide a kind of multi-screen to experience.The multi-screen business features is, in any place, any time, the ability of access communications service is provided on any equipment.For the service provider, multi-screen is professional to allow its service that personalization is provided for the user to improve user experience.For the user, the multi-screen business can move it and subscribes to through any reception in the multiple terminal equipment between diverse location content.
The exemplary professional network arrangement environment of a multi-screen that illustrates of Fig. 1.As shown in Figure 1, in this multi-screen operation system, it comprises: video content source; The multi-screen business platform, multi-screen server, file receiving system (for example receiver, video file), memory, file (for example video file) transcoding device; Three kinds of service offering networks: IPTV network, mobile radio communication, the Internet; Terminal equipment, the IPTV client through IPTV network TV reception, the portable terminal (for example mobile phone, PDA etc.) through the mobile communications network receiver, video, the individual PC (PC that contains media player like notebook computer etc.) through the Internet receiver, video.Wherein, the multi-screen business platform receives from video content source, the information of video content source for example, and it is carried out necessary processing, for example it is carried out necessary reception, format conversion, storage etc.Here, the multi-screen business platform particularly by the server in the platform, carries out unified management and scheduling to video content source.Through of be independent of each service offering Network Management and the maintenance of multi-screen business platform to information data, the service that the service offering network that makes the user of portable terminals such as having IPTV, mobile phone and individual PC can select its any terminal equipment to adapt via selected terminal equipment has visited by unified management.
Because the multi-screen business is not retrained by the single screen or the access technology of user terminal; Make the content of multimedia that available at any time any device access user is collected or subscribe to, so what give that user's PC, TV, mobile hand-held device (like mobile phone, PDA, portable game machine etc.) bring is seamless connection and seamless broadcast impression.It allows the entertainment selection of user individual customization oneself and promotes the user to share happy ability with the family and friends.This makes our various communications and entertainment business become more flexible, and better user experience quality (QoE, Quality of Experience) is provided.
A common deployment of multi-screen business platform is to cross over 3 kinds of heterogeneous networks: mobile radio communication, the Internet (can be that the fixed network access also can be the Wi-Fi wireless access), IPTV net, and as shown in Figure 1.Along with more outstanding user's mobility (having benefited from popularizing of automobile and subway), the lightening development trend of notebook computer, the scene of 3 kinds of heterogeneous networks of the professional leap of multi-screen is more and more common.
For example; Watch the professional user of multi-screen for using mobile phone (also comprising mobile hand-held devices such as PDA) through mobile communications network; In the time also can obtaining the Internet, IPTV network insertion in its inlet chamber; In view of the large-screen characteristic of PC and TV can be brought better viewing experience, he more hopes to use PC or TV to watch multi-screen professional through the Internet or IPTV network probably; And for watching the professional user of multi-screen at indoor PC or TV; Can not be at PC or TV by its timing; Taken by other kinsfolks like PC or TV; Perhaps when he will move to when outdoor, the user possibly hope to change into through mobile communications network and on mobile phone, continues to watch multi-screen professional; For another example; The user possibly watch multi-screen professional at indoor TV originally; But because the user will use PC or mobile phone to carry out interactive service in watching process; Such as the situation that certain film-pieces is carried out screenshotss or records and upload, cause the user to change into and use PC or mobile phone to continue to watch multi-screen professional.The professional situation of multi-screen is watched with mobile phone or Wi-Fi notebook computer in the place that is deployed with the mobile communications network and the Wi-Fi network coverage for the user at the same time; The user might be switched between these two kinds of networks at any time; Such as; Which kind of network wireless signal quality is better; Perhaps which kind of network rate is cheaper, and he just selects which kind of network to watch multi-screen professional through, or watches multi-screen professional with a kind of equipment that the energy content of battery is more sufficient among mobile phone and the Wi-Fi notebook computer.
This shows that the multi-screen business all might take place in any two kinds of internetwork switchings.Yet professional research does not relate to this content of network switching to multi-screen at present.The method of switching all about network at present all is about the switching of same terminal equipment in mobile communications network (the for example handover of portable terminal) or Wi-Fi network.Therefore the multi-screen business presses for the switching of real realization multi-screen business between heterogeneous network, for example between mobile communications network, the Internet, IPTV network, switches.

Embodiment
Scheme proposed by the invention service through visiting via different service offering networks to the user; Video content for example; Carry out unified maintenance and management; Make service to be visited be independent of concrete or specific service offering network and insert standard, standard accordingly, thus for the user provides at the internetwork seamless switching of different service offerings maybe.Based on the concrete condition of subscriber terminal side, when discovery need switch to new service offering network, to the user service is provided through desired service offering network.In a preferred embodiment, can be the user continuous service is provided, make the user obtain real seamless switching.
Hereinafter, will combine accompanying drawing to describe scheme of the present invention in detail.
As shown in Figure 2; In multi-screen business platform side; Can be based in the message of service quality, user preference and the user terminal of subscriber terminal side at least one, the service that determines whether this access is provided via the service offering network switch step 201.In step 202,, then, confirm the desired service offering network that switches to based on the message of service quality, user preference or the user terminal of subscriber terminal side if confirm to switch to new service offering network.At last, in step 203, carry out and switch, thereby pass through other service offering network to this user terminal, perhaps this user's other-end provides service.Here, As mentioned above, the service that is provided is independent of concrete service offering network ground management.Preferably, manage the service that provides for the multi-screen service-user, like user's login, authentication, charging, data base administration or the like through the multi-screen business platform.
Preferably, the service offering network is mobile communications network (for example GSM network, cdma network, 3G network etc.), the Internet (for example fixing/cable access network, Radio Access Network etc.), IPTV network.Correspondingly, can be with above-mentioned service offering network corresponding user terminal: various single modes, bimodulus or multi-module mobile terminal, for example mobile phone, PDA or other various portable sets; PC, net book or the like can visit the terminal of information through Internet; Television set.
Here, service quality can comprise the error rate, delay, video jitter, response time, signal quality etc.Wherein, signal quality can be weighed through parameters such as carrier interference ratio C/I (Carrier/interference), the error rate, BLER(block error rate) (BLER), signal to noise ratio (snr)s.It will be appreciated by those skilled in the art that; Also the mode of existing any appropriate capable of using is weighed signal quality; Such measurement can be accurate (as in the instantiation of hereinafter with the comparison of the threshold value that sets); Also can be rough, as long as the mode of gauge signal quality and concrete applied environment and concrete application demand adapt.
User preference comprises prioritization that the user selects, the service offering network that can insert is carried out the history of optionally connected service offering network of going into, the various information that show user preferences such as access priority to the service offering network of some situation that set.
For example; Along with the popularizing of 3G/Wi-Fi dual-mode handset or bimodulus notebook computer (at present a lot of notebook computers all are embedded with the Wi-Fi module), the covering points of WLAN (for example Wi-Fi network) and the increase day by day of area coverage, the user may switching continually between mobile communications network and the Internet when using multi-screen professional.For example; When the user gets into the Wi-Fi area of coverage; Possibly more be happy to switch to the Wi-Fi network watches multi-screen professional; Have benefited from the higher bandwidth of bigger screen, the Wi-Fi network of Wi-Fi notebook, better radio signal quality (indoor, the signal quality of Wi-Fi network is better than 3G network), lower rate (even free), the user can obtain better viewing experience.And when the user moves to beyond the Wi-Fi overlay area, just can only change into and use mobile communications network and mobile phone to continue to watch multi-screen professional.It is thus clear that for such user, it can be stored on the user terminal using the Wi-Fi network as default setting, is perhaps safeguarded by the multi-screen business platform.
Because scheme of the present invention allows the user that the preference of oneself is arranged and can manage switching according to the user preference that obtains, and therefore the user experience that seamlessly switches to the Wi-Fi network more easily is provided.Like this, can utilize the Wi-Fi network to come further to promote the user experience in the multi-screen business more fully, save the frequency spectrum resource and the Radio Resource of operator's mobile communications network simultaneously.For example; Video service in the multi-screen business is horn of plenty more; And compare with traditional voice service, transmitted video content will consume the bandwidth more than ten times, (high-definition movie 2～3GB file size often for example; Smooth playing need be at least about the 6Mbps bandwidth), so be very surprising to the consumption of wireless network resource such as frequency spectrum resource.Therefore, the Wi-Fi network that uses free ISM (industry science doctor) frequency range is exactly one well to be selected, and its bandwidth not only high (about 50Mbps) but also do not take the Radio Resource of mobile communications network relatively is fit to the application of multi-screen business.And, obviously promoted the utilization and the professional application of multi-screen of Wi-Fi network through scheme of the present invention.
Although it should be noted that preceding text is that example has been described operating process shown in Figure 2 with the multi-screen business platform.But it will be appreciated by those skilled in the art that the dual-mode/multi-mode user terminal also can carry out same flow process.
In the present invention,, both can initiate, also can initiate by user terminal from multi-screen service management side for multi-screen user's diverse network switching.The exemplary instance that the switching of being initiated by user terminal is shown of Fig. 3.Wherein, in step 301,,, determine whether to switch to other service offering network based in service quality, user preference, the user message at least one in subscriber terminal side.If confirm to switch, then in step 302, the equipment of notice management service, the multi-screen business platform of the business that provides to the multi-screen user of notice management for example, the switching carried out of determining.Wherein, the service offering network that switch to is based on that in service quality, user preference, the user message at least one confirm, and after carrying out said switching, said service is visited via the service offering network after switching.Similarly, service is independent of the management of service offering network ground.Preferably, the multi-screen business platform by the service offering network comes management service.
Here, method shown in Figure 3 typically realizes by single mode, bimodulus, multimode user terminal, for example dual-mode handset, notebook computer etc.For the user terminal of bimodulus, multimode, it will be understood by those skilled in the art that obviously except the Overall Steps of carrying out method shown in Figure 3, it possibly also confirm the service switching network that will switch to even execution handover operation.
In addition, said user message can be the message that the user initiatively fills in/sends, and also can be based on the message (possible switching will be described below to user prompt) of prompting feedback.
This shows that the switching that the present invention can be applicable to initiatively to be initiated by the user, by the switching that a side of managing service independently (for example multi-screen business platform) is carried out also can be according to user's preference and be provided with in advance and automatically switch.Below we will combine concrete application example to introduce the application to scheme of the present invention.
Because the signal area coverage of cordless communication network (comprising mobile communications network and Wi-Fi network) is limited; The signal quality of cell edge is not good; If the multi-screen video traffic that the user is watching when moving to cell edge is interrupted; Then will produce the poorest customer service and experience, this also is the situation that the service provider does one's utmost to avoid.Therefore, can with the quality of signal quality as whether being that the user provides one of criterion of switching.In this instance, we use carrier/interface ratio to weigh the quality of wireless signal.C/I (carrier/interface ratio) refers to carrier wave (C) and disturbs the ratio of (I); Be that wireless signal is in the communication process in space; At the intensity of carrier bandwidths intercarrier signal and the ratio of other interference; Unit is a decibel (dB), and it can reflect the quality of wireless signal received signal of receiving terminal in the process of spatial transmission.Particularly, corresponding to mobile communications network and Wi-Fi network, we can confirm the threshold value of receiving terminal carrier/interface ratio respectively, such as all corresponding to 1% the error rate of user terminal application layer.Then, detect,, then determine the user switched to other service offering network if radio signal quality is lower than this threshold value with the signal carrier/interface ratio of cycle regular hour to the user terminal place.Perhaps alternatively, send information to the user, the signal of the present used wireless network of prompting user is not good, and the suggestion user switches to other network.The advantage of the mode that this permission user selects is; Can select whether to switch according to the professional concrete condition of its visit multi-screen by the user; For example, if the video that this user watched closes to an end, perhaps will stop to watch current multi-screen professional, can refuse this switching so.Here, information can have various ways, for example text, picture, animation, sound or the like.After confirming to switch, shown in Fig. 2,3 method, can further confirm the service offering network that will switch to, and switch.
Like this; As long as the quality of the wireless signal that the user is received is lower than the threshold value that sets, perhaps automatically the user is switched (this is more useful to bimodulus, multimode user terminal, because can under the situation that the user does not discover, carry out seamless switching); Perhaps information is provided for the user; Be convenient to decision and preparation (can switch to the Internet of fixing/wireless access, also can switch to the IPTV network) that the user makes switching in advance, thereby improve user's business experience effectively.
For the threshold value in the preceding text, it will be understood by those skilled in the art that this threshold value can be predefined constant, also can be the variable of in using scheme process of the present invention, setting flexibly.
In another preferred embodiment, can combine user's preference and service quality to realize switching.For example, for one have 3G/Wi-Fi dual-mode handset or a bimodulus notebook computer the user, he possibly hope preferentially to use the Wi-Fi network to realize inserting.To this, can set the threshold value of a Wi-Fi receiving terminal carrier/interface ratio earlier, such as 1% the error rate corresponding to multi-screen user terminal application layer.Then; The detection of Wi-Fi wireless signal is carried out in the present region of Wi-Fi user according to cycle regular hour; If detect the Wi-Fi wireless signal (promptly the radio signal quality of this Wi-Fi network supports that enough multi-screen is professional) that is higher than the predefine threshold value, then automatically the user switched to through the Wi-Fi network and visit the multi-screen business.Similarly, also can send information to the user, there is the Wi-Fi wireless network the present region of prompting user, confirms whether will switch accordingly to the user.Like this; In case the multi-screen user terminal has detected the Wi-Fi network; And the radio signal quality of this Wi-Fi network is enough supported multi-screen professional (carrier/interface ratio is higher than threshold value); Then the user can be through pointing out the existence of in time knowing the Wi-Fi network, make in advance decision and the preparation that switches to the Wi-Fi network, thereby make full use of the business experience that the Wi-Fi network improves the user.Here, information can have various ways equally, text, picture, animation, sound etc.
In another embodiment, can be in advance according to user's preference the automatic/hand switching criterion be set, in case satisfy predefined criterion, just said switching is carried out on automatic/hand ground.
Following preferred embodiment is further experienced for the user provides seamless switching.
" service identifiers " solution has been proposed in a preferred embodiment.This service identifiers be used to distinguish offered the user with the service that does not offer the user so that after carrying out said switching, continuous unbroken service is provided for said user.Also can this service identifiers for example be interpreted as " bookmark ".This service identifiers is in the multi-screen business platform (like the multi-screen service server among Fig. 1), the mark that in any one multi-screen video frequency program (like film " batman "), adds.Because the multi-screen business is managed by the multi-screen business platform that is independent of the service offering network; Service identifiers also adds in multi-screen business platform (being the program source end); Therefore irrelevant with each service offering network (mobile communications network, the Internet, IPTV network), therefore for user experience, this mark is to all user's multi-screen terminal equipments; Three kinds of multi-screen equipment among Fig. 1 for example: mobile hand-held device, PC and TV, all effective.Thereby no matter the multi-screen user uses which kind of equipment, which kind of network to continue to watch from " service identifiers " (mark) is experienced the professional video frequency program of multi-screen that network switches, rather than begins from the beginning to watch from program.Such as; When the user watched " batman " middle leading role batman to go downstairs, he wanted handover network, and then the multi-screen business platform is set up general service identifiers herein; Like this; No matter the multi-screen user uses which kind of equipment, which kind of network instead and can continue to watch from batman this position of going downstairs, rather than begins from the beginning to watch from program, provides a kind of seamless switching to experience for the multi-screen user.
In a further advantageous embodiment, adopted the scheme that increases buffer memory.Owing to compare with traditional voice service; Transmitted video content will consume the bandwidth more than ten times; So in some cases; For example the user switches to and waits for that enough data could continue to watch multi-screen professional after getting into buffer area behind the new network possibly, service identifiers only is set possibly is not enough to the service quality that provides satisfied.To this, can be before network switch, on the multi-screen service terminal, automatically increasing should the pairing buffer memory of business, for example doubles.Like this, owing to stored enough video content data in advance for the user, even if there is time delay in the network switching, the video content data that the user still can call in the buffer memory is play, and the network handover delay experienced of user has just significantly reduced like this.This preferred version is particularly useful for the dual-mode/multi-mode terminal, and for example the user uses 3G/Wi-Fi dual-mode handset or the bimodulus notebook computer situation as the multi-screen service terminal.
In another preferred embodiment, the scheme that service pushes has in advance been proposed.Particularly, before carrying out the network switching, the service that is provided is pushed to the service offering network after will switching in advance.For example; For switching manual or that user side is initiated; The user answered whether switch or will switch to which network after, determine whether on one's own initiative will follow-up video content to be pushed in advance according to user's wish and leave the nearest network node of user in the service offering network that will switch to.For example, the IPTV network can be pushed in the STB in the users home, and the Internet can push to user's home gateway.This scheme is particularly useful for the situation that the user is switched between different service offering networks.In addition, this embodiment also is applicable to the real-time less demanding situation of user to switching.That is to say that the user does not require to switch on another network and watch that this situation is very general in fact, watches video with regard to inconvenience when driving such as the user, while the user walks to watch the situation of video also few at once.In fact, it is not very long that video content pushes the required time in advance, even can push a video segment a few second.So the use that meets application demand of this embodiment can improve user's business experience further.
It should be noted that for above-mentioned interpolation service identifiers, the preferred implementation that increases buffer memory, push in advance, the use to other embodiment is not got rid of in the use of a certain embodiment wherein.In other words, one of ordinary skill in the art will readily recognize that can be with the use that at random combines of above-mentioned three kinds of modes, thereby reaches desired service quality or user experience quality.For the enforcement of above-mentioned optimal way, it can be carried out any suitable time in said method, for example between Fig. 2, the step 202/302 shown in 3 and 203/303, is carrying out.For increasing buffer memory, obviously it carries out interrupting being connected between user and the current service offering network before.Alternatively, obviously, for adding service identifiers, pushing in advance, it can also carry out with switching basic synchronization ground.In a word, no matter adopt which type of sequential, the short of original intention that deviates from when proposed by the invention gets final product.
Preceding text have been described the method for scheme of the present invention.It will be appreciated by those skilled in the art that it can realize with software, also can be with the form of software and hardware combining, and perhaps hardware is realized.And each step in the method mentioned above can be merged in order to adapt to the certain applications environment, or is further split or suitably revised.But the said method concentrated area is carried out, is carried out in subscriber terminal side in a side of management service independently, also can be scattered on the existing distinct device and carry out.
In addition, realize that equipment of the present invention can be as shown in Figure 4, it includes and is respectively applied for execution and Fig. 2, the corresponding device of the method shown in 3.When this equipment was deployed on the multi-screen business platform, alternatively, this equipment can include the Service Management device, data storage device for example as shown in Figure 1, and perhaps this equipment can be communicated by letter with corresponding data storage device.Wherein, said Service Management device can the maintenance customer and its multi-screen service terminal between relation, map information etc. for example; Perhaps be used for adding the service identifiers that preceding text are mentioned to service; Perhaps whether management increases the operations such as propelling movement in advance of buffer memory, service.To those skilled in the art, such equipment can have software flow to realize, and loads in existing equipment, the system, and simultaneously, it also can be realized by hardware.
Fig. 5 is exemplary to illustrate a schematic diagram that is used to realize user terminal of the present invention.It includes: transceiver is used for carrying out alternately with the service offering network; Switch unit is used to carry out the switching of service offering network, so that visit service through the service offering network after switching via said transceiver.Wherein, determine whether to carry out based on the user's of the service quality of this equipment side and/or user preference or this equipment message and switch, and said service is independent of said service offering network ground and manages.Equipment shown in Figure 5 can be realized by hardware, for example the professional terminal of user's visit multi-screen, for example mobile phone.
