Abstract
Abstract The invention is characterized in that parts of a multimedia service which is executed in a mobile terminal is structured in form of different software components. The structure implies that an operator who provides the service is given possibility to distribute the service in different parts via a data connection, control channel, to a user terminal. This implies that the service is divided into a number of software components such as control application, applications for video, audio, data etc, and a service function. By structuring the service in this way, the operator can tailor and, when applicable, upgrade a multimedia service in a user terminal by loading down, via the control channel, different versions of software components.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
Device at a mobile telecommunications system or data communications system which makes possible that one in said system provided multimedia service can be changed to fit the need of different users and geographical areas within which said users can be in said system, characterized in that it includes just any number of units (1, 2, 3, 4, 5, 6), at which in each of said units are stored, updated and executed specific software components, which correspond to parts of a complete multimedia service, based on the functions of said units.
Claim 2
Dependent Claim
45 words
Device according to patent claim 1, characterized in that said software components corresponding to a part/parts of a multimedia service, or a complete multimedia service, are transmitted by an operator via a control channel and implemented in said units (1, 2, 3, 4, 5, 6).
Claim 3
Dependent Claim
44 words
Device according to patent claim 2, characterized in that said units consist of a control application unit (1), a service function unit (2), a video application unit (3), an audio application unit (4), a data application unit (5) and an access function unit (6).
Claim 4
Dependent Claim
134 words
Device according to patent claim 3, characterized in that said control application unit (1) is used by the user to control the mobile multimedia service and obtain information about the behaviour of said service, said video (3), audio (4), data application units (5) contain functionalities to communicate with the world around and internally process incoming or outgoing information, said service function unit (2) controls the behaviour of the mobile multimedia service and controls the application units (3, 4, 5) based on the wishes of said users and the service construction of said operator, said access function unit includes logic which attends to signalling to the fixed network, which is needed to establish a connection, control and surveillance of the bandwidth utilization of the mobile terminal and to decide which handover algorithm that is suitable.
Claim 5
Dependent Claim
36 words
Device according to any of the previous patent claims, characterized in that said units (1, 2, 3, 4, 5, 6) in said mobile terminal are loaded with said software components via an Ethernet-connection or a CD-ROM-disk.
Claim 6
Dependent Claim
89 words
Method at a mobile telecommunications system or data communications system which makes possible that one in said system provided multimedia service can be changed to fit the needs of different users and geographical areas within which said users can be in said system, characterized in that said, by an operator provided, multimedia service is structured in form of just any number of software components, at which said operator distributes said multimedia service in different parts corresponding to said software components via a control channel to a mobile user terminal.
Claim 7
Dependent Claim
36 words
Method according to patent claim 6, characterized in that said multimedia service is divided into a number of software components, such as control applications, applications for video, audio, data, service function applications and access function applications.
Claim 8
Dependent Claim
47 words
Method according to patent claim 7, characterized in that said operator upgrades or transmits said multimedia service to a mobile user terminal by, via the control channel, only loading down the software component or components which are required for that said terminal shall obtain requested multimedia service.
Claim 9
Dependent Claim
24 words
Method according to patent claim 8, characterized in that said mobile terminal is loaded with said software components via an Ethernet-connection or a CD-ROM-disk.
