Description

Informing recipient device of message content properties

The present invention relates to the field of notification of message content attributes to a recipient device.

Short message services are now very common. In addition to text-based short messages, there is also a need for means for transmitting multimedia data. Multimedia messaging service (MMS) is a service developed for transmitting messages in various content types such as video, audio and images. 3rd Generation Partnership Project ^{(3 rd Generation Partnership Project; 3GPP} ) specification TS 23.140 v. 6.7.0 " Multimedia Messaging Service ( Multimedia Messaging Service ; MMS ); Description (Functional Description ); Stage 2 "In September 2004, the basic functions of MMS are described.

The multimedia messaging service may be configured in an environment that includes other network types. The 3GPP MMS environment may include 2G and 3G networks and provides all the necessary service elements for multimedia messaging such as delivery, storage and notification functions. The MMS relay / server performs storage and handling of incoming and outgoing messages and transfers of messages between different messaging systems. The MMS user agent resides on a mobile terminal sending or receiving multimedia messages. In this case, the MMS user agent is an application layer function that provides users with the ability to view, compose and handle multimedia messages (MM).

Multiple content types may be sent by MMS. The MM describes "jpeg" when a content type of a message, for example, an image in jpeg format, is transmitted. The sender user agent adds an identifier of the MM's multi-purpose Internet mail extensions (MIME) content type to the MM packet data unit (PDU). The identifier of the MIME content type is sent to the recipient user agent by each MMS relay / server.

3GPP MMS also supports content adaptation. Many content classes are described in the Open Mobile Alliance (OMA) specification " MMS Conformance Literature ( MMS). Conformance Document 1.2) Candidate Version, specified on July 27, 2004. The content classes illustrated in Table 1 define the content classifications. Each content class must be supported by the user agent to support the content class. An identifier of one of the content classes may be included in the MM from the calling user agent if the content of the MM conforms to the requirements of the content class. In addition to other content information, such as an indication of the existence of Digital Rights Management (DMR) protection, it may be provided to the MMS relay / server by the calling MMS user agent. You can use this content class information to identify the recipient. Adaptation is necessary based on the nature of the agent and the received content class (receiver) can be an MMS relay / server definition.

If the receiver terminal wants to acquire the details of the content of the received MM (in addition to the content type), the receiver terminal needs to perform an analysis of the content, that is to say, the body part of the MM. This can be a very complex process and requires time and processing resources.

It is an object of the present invention to provide an improved content attribute information solution. The object of the invention is achieved by methods, network elements and mobile terminals characterized by what is stated in the independent claims. Some embodiments of the invention are disclosed in the dependent claims.

According to one embodiment of the invention, the content class of the data set for the message to be sent to the recipient device is defined. The network element sending messages to the recipient device specifies at least one information element in a message for the recipient terminal such that the information element includes an indication of the content class. The message is sent to the recipient device.

According to another embodiment of the present invention, a network element for sending messages to a recipient device may define whether the data set for the message to be sent to the recipient device includes an element whose usage is restricted. The network element specifies at least one information element in a message to the recipient terminal such that the information element includes an indication of usage restricted content in response to a data set comprising one or more elements whose use is restricted. The message is then sent to the recipient device.

The term "data set" generally refers to any kind of information set that can be transmitted to a recipient via messaging, and can include multiple media types. The term " content class " generally refers to information associated with one or more requests for which the data set is performed, without being limited to content classes specified for 3GPP MMS. It should also be noted that the definition of the content class of a dataset or the definition of the application of usage restrictions in a dataset generally refers to any kind of activity from which information about the application of a content class or usage restriction can be obtained. It should be understood as. Likewise, a specification for an information element that includes an indication of a content class or an information element that includes an indication of restricted use content should generally be understood to refer to any kind of activity that generates this information for a message to be sent to a recipient device. Is that. For example, this information can be displayed in the received message, which can simply be copied in the message to be sent.

An advantage for this embodiment of the present invention is that an indication of the usage rights control content and / or an indication of the content type can be conveyed to the recipient terminal. Based on the indication, the receiver terminal can easily detect whether the use of the content is restricted and / or the content class to which the received content belongs. This is important for devices with relatively few memory / processing resources, such as several mobile phones. Moreover, less battery resources are consumed as less processing of the received message is needed.

Hereinafter, some embodiments of the present invention will be described in more detail through some embodiments with reference to the accompanying drawings.

The MMS relay / server element 20 may be configured such as generation of charging data records (CDR), negotiation of terminal capabilities, or media type / media format conversion based on the capability of the receiver terminal 10. It can provide additional functions. The MMS server / relay element 20 may be connected to other networks such as the Internet 50 and other mobile networks 30. The MMS environment may also include dedicated data storage locations (DB) 40, such as a message database for temporary storage of multimedia messages and a user database comprising user specific data. One user database is the home location regitry (HLR) of the 3GPP mobile system. The MMS server / relay element 20 may also be connected to other devices and functions, for example MMS value added services (VAS) applications. IP network 50 may be used to communicate with roaming MMS user agents 11 or wired e-mail clients, for example. Although not shown in FIG. 1, the MMS system may include an MMS proxy-relay for transmitting multimedia messages. See 3GPP Specification TS 23.140 v. For a more detailed description of the pre-specified MMS environment and MMS functions in the user agent 11 and the MMS service / relay element 20. 6.7.0 " Multimedia Messaging Service ( Multimedia Messaging Service ; MMS ); Functions (Functional Description); Stage 2 " , September 2004, especially Chapters 5-7.

The mobile terminal 10 and the MMS server / relay element 20 comprise a processing unit comprising a memory, a transceiver constituting a data transmission, and one or more processors. Computer program codes executed in such processing units may be used to enable such devices 10, 20 to implement means for providing the functions of the present invention relating to constructing the utilization of content attributes, some of which An embodiment will be illustrated below in connection with FIGS. 2-6. In one embodiment, the modified MMS user agent 11 and the modified MMS server 21 and / or relay 22 perform at least some of the functions of the present invention illustrated below. Modifications may be implemented by specific program code portions of software for implementing the MMS user agent 11 and the MMS server 21 and / or the relay 22. However, it should be noted here that the functions of the present invention may be performed by other entities.

A chip unit or other type of module for controlling the devices 10 and / or 20 may, in one embodiment, allow such devices 10 and / or 20 to perform the functions of the present invention. The module may form part of the device 10 and / or 20 and may be removable, that is, the module may be inserted into another unit or device. The computer program codes may be received over a network and / or stored on a memory means, for example a disk, a CD-ROM disk or other external memory, from which the computer program codes are stored in the data processing devices 100, 200. Can be loaded into memory. Such computer programs can also be loaded over a network, for example by using a TCP / IP protocol stack. Hardware solutions or a combination of hardware and software can also be used to implement the functions of the present invention.

2 illustrates a method according to an embodiment of the present invention for the use of content classes. The method illustrated in FIG. 2 can be applied to a parameter for transmitting messages to a receiver, in the embodiment of the invention (receiver) MMS server / relay element 20 for sending multimedia messages to a recipient MMS agent 11. The content class is associated with one or more requests that need to be performed so that a data set (which forms at least part of the content of a multimedia message) belongs to or is associated with the content class. Certain content class groups are specified in the system such that at least most of the delivered multimedia messages belong to a particular content class. In step 201, a message is received. The message may be another type of message in which a multimedia message or content may be transmitted to the receiver terminal 10 as a multimedia message. The message may be a sender MMS user agent 11, another MMS server / relay element 20 if the sender of the message resides in an area of another MMS server / relay element 20, or the MMS. It may be received from another content provider that may be outside of the environment. In step 202, the content class of the content of the message is defined. It should be noted here that in a variant embodiment only a portion of the content class of the content of the message received in step 201 may be defined in step 202. In step 202, the content class may be defined based on a content class indication in the received message. Thus, the MMS relay / server element 20 may be configured to examine the information element representing the content class in step 202 to define the content class. Alternatively, in step 202 the content class is defined based on the analysis of the content or based on modifications to the content. In one example, the MMS server / relay element 20 may perform the adaptation of the content of the received message and specify a suitable content class for the content being adapted.

In step 203 an indication of the content class is specified in the message to be sent to the recipient terminal 10. This step may be part of the formation of an MMS PDU that includes the content of the message received in step 201. In one embodiment, a specific header containing an indication of the content class is added to the PDU at step 203. After the preparation of the message, the message can be sent to a receiver device, in the embodiment of the invention, to a receiver terminal 10 comprising the MMS user agent 11. It should be noted here that such a transmission may require a specific request from the receiver terminal 10, for example after notification of a received message from the MMS server / relay element 20.

FIG. 3 shows the same embodiment as in FIG. 2, that is, one embodiment regarding the utilization of content classes. The method illustrated in FIG. 3 can be applied to a receiver device, a user terminal 10 comprising the MMS user agent 11 in an embodiment of the invention. In step 301 a multimedia message is received. The content class of the received multimedia message is checked (step 302). In one embodiment the content class is defined by examining the content of a particular MMS header that represents at least one content class associated with the multimedia message.

The recipient device 10 may be configured to adapt the processing of the message content according to the content class defined at step 302. Such processing will generally be understood to include one or more additional operations on message content that store the content, present the content, or modify the content. Thus, the content class represented in the message may affect additional operations on the message content. In the embodiment of Figure 3, the processing of the message content is adapted based on a check for support of the content class.

In step 303, the user terminal 10 checks whether the content class is supported. In one embodiment this step 303 is performed by comparing the content class defined in step 302 to certain content classes supported by the user terminal 10. Certain supported content classes can be specified based on the properties of the user terminal 10, for example screen characteristics and supported applications on the user terminal 10, for example a specific terminal capability file. Can be stored in. If the content class of the received message is supported, the message is also used in the user terminal 10 when appropriate (step 304). Typically, the content of the message is presented and stored.

In one embodiment, the presentation of the media object may be prepared based on the detected content class (eg, at step 304), that is, prior to the presentation of the content based on the singular detected content class. Prompt treatment can be applied. For example, a video player is applied for a message representing a content class for video, while no media player is needed for a message representing a text content class.

In another embodiment, the user terminal 10 is configured to store message content according to the identified content class. In the user terminal 10, content class dedicated storage locations may exist. For example, the content of a received MM having a content class for images is stored in a specific image folder. The message content can also be additionally modified.

If the content class is not supported, in the embodiment of the present invention the user terminal 10 is configured to determine (step 305) whether the adaptation of the content is available. Such an adaptation can be used to change the content of the received message so that the content can be presented at the recipient terminal 10. If no adaptation is available, the message content is discarded or only some of the content is used. It should be noted here that the message may be stored at step 307 even though it is not possible to present the content of the message by itself. If a suitable adaptation is available, content adaptation to the class or presentation format supported by the receiver terminal 10 may be performed at step 306.

4 and 5 show another embodiment of the present invention, i.e., a DRM protection indication of a message to a recipient. 4 shows the functions that can be applied to an intermediary device, such as the MMS server / relay element 20. In step 401 a multimedia message or other type of message (sent to the recipient as a multimedia message) is received. In step 402 the content of the message may be checked to define whether DRM protection is applied to any portion of the message content. To this end, in step 402 the received body part of the received message may be analyzed. In a variant embodiment, step 402 defines whether at least some of the message content is subject to DRM protection by examining a particular header or other type of information element in the received message indicating the presence of DRM protection. When DRM protection is applied based on the checks 402 and 403, an indication of DRM protection is specified in step 406 in the multimedia message to be sent to the recipient terminal 10. In one embodiment, a specific header containing an indication of DRM protection is added within an MMS PDU containing the content of the received message. Alternatively, if DRM protection is not applied to the content of the received message, the multimedia message for the recipient may be prepared without the DRM protection indication (step 404). In a variant embodiment the message is prepared to cause the message to specifically indicate that no DRM protection is applied to the message content (step 404. After step 404 or 406 the message is received by the receiver terminal 10). May be sent (step 407).

FIG. 5 illustrates functions that can be applied to a receiver device, a user terminal 10 including the MMS user agent 11 in the embodiment of the present invention. In step 501 a multimedia message is received. The receiver terminal 10 is configured to check in step 502 whether the message includes a DRM protection indication. Likewise described with reference to FIGS. 3 and 302, there are alternative embodiments for constructing an indication of this content characteristic for the recipient terminal 10. In one embodiment, the particular header of the multimedia message is examined at step 502.

Based on steps 502 and 503, the user terminal 10 may be configured to adapt one or more additional operations to the content or portion of the received message in response to an information element representing data protection. If DRM protection is to be applied based on the check 502, 503, DRM activity may be initiated at step 504. For example, the MMS user agent 11 may call the DRM client of the user terminal 10 to handle DRM protected content of the received message. The DRM client may then encode, decode and / or store the DRM protected content, for example. Please refer to the OMA DRM specifications for a more detailed description of the DRM functions provided by these functions and the available usage restrictions. Thus, the receiver terminal 10 may be configured to adapt additional processing for at least some of the message content by initiating a DRM process. In one scenario, the message may contain a locked (encrypted) media object, such as a music video presentation, which can only be unlocked (decrypted) with an unlock (decryption) key obtained by a licensing procedure with an external licensing server. Include. The procedure for obtaining the license and the unlock key may be initiated based on the DRM protection indication in the received message.

Alternatively, if no DRM protection is applied, the message content can be used when appropriate without any specific DRM functions in step 505. Typically the message content is presented and stored.

In one embodiment, the MMS server / relay element 20 is configured to check (after step 201 and / or step 401) whether the received message includes an indication of DRM protection and / or content class. do. This check may be performed by analyzing the header portions of the received MMS submitted PDU. If the message includes such an indication, the MMS server / relay element 20 may display such an indication (at step 202 in the case of the embodiment of FIG. 2 or at step 404 or 406 of the embodiment of FIG. 4). And copying at least one including header from the received submission message to the recipient terminal 10 as a search / delivery PDU. Thus, the MMS relay / server element 20 does not need to automatically generate information, so that the load on the MMS relay / server element 20 is not expected to increase. In the absence of any indication of DRM protection and / or content class, the MMS server / relay element 20 analyzes the content of the received PUD and applies this information with respect to the content class and / or DRM protection applied. May be configured to omit DRM protection and / or indication of the content class in the search / delivery PDU to be determined or transmitted to the recipient terminal 10.

In a similar manner as in the above-mentioned embodiment, the user terminal 10 also comprising the MMS user agent 11 may apply (eg, in steps 302/502) DRM protection and / or content class. It can be configured to perform the checking step for the indication of. If no indication is available, the user terminal 10 performs the analysis of the content of the received message to identify the content class and / or apply DRM protection (instead of steps 303/503). can do.

In one embodiment, the application of DRM protection and / or an indication of the content class is specified in the MMS header of the MM PDU. Thus, the MMS server / relay element 20 may be configured to add at least one MMS header that includes a DRM protection and / or an indication of the content class. In a variant embodiment the application of DRM protection and / or an indication of the content class is specified in a notification message informing the recipient terminal 10 of the received MM. Thus, the content and indication of the received message can be sent in separate messages. Based on the content class indication and / or the indication regarding the application of DRM protection, the receiver terminal 10 may be configured from the MMS server / relay 20 instead of the embodiment illustrated above in connection with FIGS. 3 and 4. It may be determined whether the transmission of the message content should be requested.

6 illustrates representative new header fields for a 3GPP MMS system. Such new header fields may also be specified in OMA MMS specifications. The header field "X-Mms-Content-Class" may be used to indicate a content class value. The value of this header " X-Mms-Content-Class " depends on the applicable media type / format, maximum size, maximum resolution of the image / video, available presentation mechanism, and / or applicable DRM method, depending on the classification applied. Provide information. The header field "X-Mms-DRM-Content" may be used to indicate the presence of DRM content. Such a header field may simply have a value of 'Yes' or 'No'. The headers are optional because some messages may not belong to any content class and some messages may not contain any DRM-protected content or are not available to the MMS server / relay element 20. Because. It should be noted here that there are several variants of representing DRM protection and / or content classes. For example, a single header can be used. The presence of DRM content may also be additionally specified, for example by indicating content elements that are protected by DRM.

In another embodiment, the content class is previously associated with more detailed information about the DRM protection method or type. Thus, based on the detected more detailed information, the receiver terminal 10 may be configured to adapt additional DRM protection before and after step 504 of FIG. For example, the content class may specify a forwarding prevention purpose (forward lock), whereby forwarding of the content is prevented at the user terminal 10. Other representative DRM protection methods that may be indicated in the DRM header field of FIG. 6 or in other types of DRM indication headers are Combined Deliver and Separate Delivery. It should be noted here that the applicable usage restriction methods are not limited to DRM methods and any kind of usage restriction may be displayed on the receiver terminal 10. For example, a specific time limit, user limit, user group limit, financial limit, device limit, or application limit may be displayed.

30 kB의 최대 크기는 기본적인 이미지 클래스에 대한 요구이다. 따라서, 이미지를 포함하는 메시지는 (예를 들면 단계(202)에서 MMS 서버/릴레이 요소(20)에 의해) 기본 이미지 클래스와 연관되게 하기 위해 30 KB보다 클 수 없다. 더욱이, 상기 수신자 단말기(10)는 다른 소정의 콘텐츠 클래스들과 연관되거나 다른 소정의 콘텐츠 클래스들에 의해 명시되는 요구들을 인식하고 있다. 상기 콘텐츠 클래스를 식별한 다음에, 상기 사용자 단말기(10)는 상기 수신된 메시지의 콘텐츠 클래스를 기반으로 하여 적합한 부가적인 동작들을 개시할 수 있다. 예를 들면, 상기 기본 이미지 클래스와 연관된 메시지가 수신될 경우에, 상기 수신자 단말기(10)는 상기 메시지를 저장하기 위한 충분한 이용가능 메모리 공간을 지니고 있는지를 결정할 수 있다. 만약 상기 수신자 단말기(10)가 상기 메시지를 저장하기 위한 충분한 이용가능 메모리 공간을 지니고 있지 않다면, 사용자는 통보를 받을 수 있으며 그리고/또는 이용가능 메모리 공간이 예컨대 가능하다면 증가될 수 있다.As mentioned above, a content class is associated with or specifies one or more requests for which a data set (which is part of the content of a multimedia message or an aggregate message) is performed. It may be specified when the above requirements are appropriate to classify the transmission data to support interoperability between devices. Thus, transport (payload) data sets with similar properties are associated with the same content class. Some representative requirements categories that can be applied and displayed in the header of FIG. 6 in one embodiment are the size of the content, the text format of the content, the image format of the content, the bitmap format of the content, the video format of the content, the audio format of the content. , Personal Information Management (PIM) format of content, DRM protected mode of content, and presentation format of content. For example,

The maximum size of 30 kB is a requirement for a basic image class. Thus, the message containing the image may not be larger than 30 KB to be associated with the base image class (eg, by the MMS server / relay element 20 in step 202). Moreover, the receiver terminal 10 is aware of the requests associated with or specified by other predetermined content classes. After identifying the content class, the user terminal 10 may initiate appropriate additional actions based on the content class of the received message. For example, when a message associated with the base image class is received, the receiver terminal 10 can determine whether it has enough available memory space to store the message. If the receiver terminal 10 does not have enough available memory space to store the message, the user may be informed and / or the available memory space may be increased, for example if possible.

In one embodiment at least some of the content classes such as text, base image, rich image, base video, rich video, megapixels, basic content, rich content are employed to classify the content. However, the presentation of content types is not limited to any particular content types. In one embodiment, the OMA specification " MMS conformance literature ( MMS Conformance Document 1.2) Candidate Version The properties specified in chapter 7 of July 27, 2004 are employed in classes such as text, base image, base video, and rich video. See the embodiment of FIG. The header field "X-Mms-Content-Class" may consequently have one of these values, for example, certain specific binary values for each of the content classes of these content classes may be applied. Based on this, the MMS user agent 11 and the MMS relay / server functions 21 and 22 define and identify content classes of multimedia messages.

It should be noted here that the embodiments described above may also be applied in any combination thereof. As will be apparent to those skilled in the art, as the technology evolves, the concepts of the present invention can be implemented in various ways. The invention and its embodiments are not limited to the examples described above but may vary within the scope of the claims.
