In different IPTV-services a subscriber can for example watch TV- programs, store or record desired TV-programs into a network storage space and watch them at any desired time, as well as rent and watch movies made available through a rental movie service.
The present application provides a novel solution for mobile use of a media service, such as an IPTV-service. According to a first example aspect of the invention there is provided a method for providing a media service to mobile devices comprising
forming an IP-connection between a mobile device and the media service, receiving over said IP-connection at least one identifier used in a mobile network,
automatically recognizing a user of the mobile device based on said at least one identifier used in a mobile network,
automatically choosing based on user information of the recognized user at least one media recording for anticipated download, and
sending to the mobile device download information for anticipatory download on the media recording chosen for anticipatory download before receiving a viewing request concerning said media recording that is possibly received later from said mobile device.
In an example embodiment the sending is carried out in response to a request received from the mobile device.
In an example embodiment the method further comprises starting the transfer of the media recording chosen for anticipatory download to said mobile device before receiving a viewing request concerning said media recording that is possibly received later from said mobile device.
In an example embodiment the method further comprises ascertaining from systems of the mobile network that the recognized user is a valid user.
According to a second example aspect of the invention there is provided a method in a subscriber application, using a media service, of a mobile device, comprising forming an IP-connection between the subscriber application and the media service,

Fig. 1 shows a system according to an embodiment of the invention;
Fig. 2 shows a messaging chart according to an embodiment of the invention;
Fig. 3 shows an apparatus according to an embodiment of the invention; Fig. 4 shows a method according to an embodiment of the invention; and Fig. 5 shows a method according to a further embodiment of the invention.
In an embodiment of the invention, the media service has been realized in such a way that mobile users are recognized without the users having to provide specific sign in-information (e.g. user id and password). User recognition utilizes identifiers of a mobile network which identifiers are available for example on the Subscriber Identity Module (SIM) -card of the mobile device. In an embodiment of the invention content that is likely to interest the user is downloaded into the mobile device in an anticipatory manner. Since the user is automatically recognized, anticipatory download does not require any actions from the user but can be carried out fully automatically even without the user being aware that the anticipatory download is being carried out.
Herein a mobile device refers to an electronic device suitable for wireless communications and especially to an electronic device utilizing a mobile communications network. The mobile device may be for example a mobile communications device, a smart phone, a tablet computer or other portable communications device.
Fig. 1 shows a system according to an embodiment of the invention. It should be noted that the figure comprises both separate physical devices and different logical components, the functions of which might be carried out in one or several physical devices.
The system comprises a portal 101 offering IPTV-services or the like. In practice the portal 101 is for example a web page situated at a server. In addition to the IPTV-services the portal may be another media portal offering media content.
The portal 101 is connected to an IP-network 105 and therethrough to a wireless network 103 and to a mobile device 102. The wireless network 103 may be for example a GSM/GPRS-network or UMTS-network or other wireless communications network or a WLAN-network. The mobile device may be for example a mobile communications device, a smart phone, a tablet computer or other electronic device utilizing a mobile communications network or wireless network, or other wireless device suitable for viewing moving image/video. The IP- network may comprise several different networks, such as Internet and different broadband networks, such as ADSL, VDSL and Ethernet-networks, and wireless networks, like WLAN-networks.
The portal 101 is connected to a user database (user DB) 111 with which the users of the portal 101 are recognized. The portal 101 is also connected to a recommendation engine element 112, which produces user- or usergroup-specific program or content recommendations. The recommendation engine element 112 is connected to a statistics database 113, into which usage information on the realized usage of the portal 101 has been collected from different user devices 102. The recommendation engine element 112 is configured to use the information contained in the statistics database 113 to form program and/or content recommendations.
In addition, the portal 101 is connected to a media storage 114. The media storage 114 may comprise media recordings offered by a third party and/or content governed by the provider of the portal 101. There may be one or several media storages 114.
The portal 101 is configured for distributing a media transmission, such as a TV or video transmission, to the mobile device 102 through the IP-network 105 and the wireless network 103 for example based on IPTV technology. The distribution may be carried out using for example Real Time Streaming Protocol (RTSP), Real Time Messaging Protocol (RTMP) or Hypertext Transfer Protocol (HTTP). The distribution may be carried out through the portal 101 or the portal 101 may control a distribution directly from the media storage 114 to the IP-network 105 and therethrough to the mobile device 102. In an embodiment, the media storage 1 4 is connected to a media server 115 and therethrough to the IP-network 105. In addition or alternatively recordings can be fetched directly from the media storage 1 4 through the media server 115.
In an embodiment, each of the portal 101 , the user database 111 , the statistics database 113, the recommendation engine 112 and the media storage 114 of Fig. 1 is a separate physical device. In another embodiment the functionality of the portal 101 , the user database 111 , the statistics database 113 and the recommendation engine 112 of Fig. 1 may be combined into a single logical entity provided by a single physical device (or several similar parallel devices). In other words, all intelligence of the service is situated in a single device and the service utilizes content and program information available from external sources (media storage 114). Alternatively, it is possible that the media storage 114 and the possible media server 115 are situated in the same physical device or at least are in control of the party offering the IPTV service of the portal 101. In such a case, the content of the media storage 114 may be retrieved, downloaded or stored from an external source.
Accordingly, the functionality of the components 101 , 11 -115 of the system of Fig. 1 may be carried out in one or several devices. If need be, there may be several parallel devices providing the same functionality for example for evening the load.
Fig. 2 shows a messaging chart according to an embodiment of the invention that can be realized for example in the system of Fig. 1.
201 : The subscriber application of a mobile device sends a sign-in request to a media service portal. The sign-in request comprises at least one identifier relating to the mobile device, and intended primarily for use in a mobile network. This identifier may be for example an IMSI (international mobile subscription identifier) or an IMEI (international mobile equipment identifier) identifier and the subscriber application may fetch this information for example from a SIM (Subscriber identity Module) card residing in the mobile device. In an embodiment the identifier is sent and received in an encrypted form in order to guarantee data security. For example a hash can be calculated from the identifier, which hash is sent to the media service portal.
This phase can be carried out automatically, without the user of the mobile device having to perform any operation, for example when the mobile device is switched on or the subscriber application is started.
202: The portal authenticates the user based on the identifier received with the sign-in request and based on user information stored in a user database. This phase may comprise a separate confirmation that the identifiers in question are not on a blacklist of any mobile communications network. This way it is possible to ascertain for example that the mobile device in question has not been reported stolen. Respectively, it can be checked that the user has a valid subscription to the media service.
203: The portal acknowledges the successful sign-in to the subscriber application.
204: The subscriber application may enquire from the portal, whether any material for anticipatory download is available at the portal. The subscriber application may be configured to send such an enquiry for example in response the subscriber application detecting that the mobile device is not being actively used for any other purpose and/or that the mobile device would have free processing capacity. Alternatively or in addition, the subscriber application may be configured to send such an enquiry recurrently. However, sending an enquiry 204 is not essential to different embodiments of the invention and the embodiments of the invention can be realized fine without this enquiry.
205: The portal requests a user specific recommendation for anticipatory download from a recommendation engine.
206: The recommendation engine forms a recommendation based on user information retrievable from a statistics database. The recommendation engine may form recommendations in real-time as they are needed or the recommendations may be pre-stored in the recommendation engine. In the latter case the recommendation engine doesn't need to be in contact with the statistics database each time it is being requested for a recommendation for a user. 207: The recommendation engine returns a user specific recommendation to the portal.
208: The portal sends to the subscriber application download information that tells from where the subscriber application may download anticipatorily the content recommended for the user in question. Said content may comprise on or more media recordings.
209: The subscriber application sends to the portal a download request for anticipatory download of a media recording. The subscriber application may be configured to send the request for example in response to the subscriber application detecting that the mobile device is not being actively used for any other purpose and/or that the mobile device would have free processing capacity and/or that the properties of a mobile network used by the mobile device are well suited for download (for example a fast enough network, sufficient transmit power) and/or that the mobile device has a sufficient battery level.
210: The portal authorizes the usage right of the user on the media recording requested for download. 211 : The portal sends a request to a media storage to start sending the requested media recording to the mobile device.
212: In the depicted example, the media recording is sent directly from the media storage to a memory device of the mobile device. Alternatively, the media recording may be dispatched to the mobile device through the portal and in the mobile device the media recording may be dispatched into the subscriber application that further stores it into the memory device of the mobile device. 213: The user of the mobile device wants to watch a media recording downloaded anticipatorily. The recording is retrieved from the memory device instead of having to download it from the portal. In an embodiment, a part of the recording may be retrieved from the portal. This may be done for example when there has been time to download anticipatorily only a part of the recording at the time the user starts viewing the recording.
Here it should be noted that only one example implementation has been shown in Fig. 2 and all the phases are not obligatory. In addition, the details of the implementation may vary in different embodiments. For example, the download request 209 may be sent directly to the media storage or to a front end device (for example media server 115 of Fig. 1 ). The connections, through which recordings can be downloaded directly from the media storage 114, have been shown with a dash line in Fig. 1. In this case, the media server 115 may be configured to authorize with the help of user database 11 the usage right of the user to the content that is requested for download.
Fig. 3 shows an example of an apparatus 30 that is suitable for carrying out some embodiments of the invention. The apparatus may be for example a general use computer or a server and it can be configured for providing the functionality of one or more components 101 , 111 -115, 102 of Fig. 1.
