Abstract: The invention relates to a method of managing control data of a mobile station (MS), in which method a triggering condition is defined, the fulfilment of the triggering condition is waited for, control data are transferred to the mobile station (MS), and the control data are stored in the mobile station (MS). The method comprises defining a control data reception command for the mobile station (MS), transferring, once the triggering condition is fulfilled, to the subscriber identity module (SIM) of the mobile station (MS) information on control data to be transferred to the mobile station (MS), and issuing the control data reception command from the subscriber identity module (SIM) of the mobile station (MS) to a mobile equipment (ME).

Description: MANAGING CONTROL DATA IN MOBILE STATION [0001] The invention relates to managing the functions of a mobile station and particularly to updating control data in a mobile station. [0002] Solutions are previously known wherein the user of a mobile station updates the settings of the mobile station via a network server. This allows the user for instance to use a personal computer to establish a connection to the www page (World Wide Web) of a network operator, after which the settings are transferred as an SM command (Smart Messaging) to the mobile station. Upon reception of the settings, the mobile station may inquire of the user if the settings are to be stored in the memory of the mobile station. Alternatively, the user may contact the operator by means of a short message, after which the settings are transferred to the mobile station. [0003] The problem in the above arrangements is that the user must decide upon the retrieval of settings from a server. If the user does not know how to update the settings in a mobile station, then the settings of his mobile station do not change at all. If, again, the user knows the settings update procedure, but establishes a connection to the server only seldom, new settings are difficult to obtain rapidly to the mobile station. [0004] The object of the invention is thus to provide a method and equipment for implementing the method so as to solve the above problems. The object of the invention is achieved by a method of managing control data of a mobile station, in which method a triggering condition is defined for changing the control data of the mobile station, the fulfilment of the triggering condition is waited for, control data are transferred to the mobile station, and the control data are stored in the mobile station. Said method is characterized by defining a control data reception command for the mobile station, storing the triggering condition in a subscriber identity module, transferring, once the triggering condition is fulfilled, to the subscriber identity module of the mobile station information on control data to be transferred to the mobile station, issuing the control data reception command from the subscriber identity module of the mobile station to mobile equipment, and receiving and storing the control data in the mobile equipment. [0005] The invention also relates to a mobile system comprising at least a mobile station operating in a mobile network and comprising a mobile equipment and a subscriber identity module, and a server in the mobile network. Said mobile system is characterized in that the subscriber identity mod- ule comprises means for storing a triggering condition, means for detecting the fulfilment of the defined triggering condition, means for receiving information about the control data to be transferred to the mobile station, and means for issuing a control data reception command to said mobile equipment based on the received information about the control data, the mobile equipment comprises means for receiving the control data reception command from the subscriber identity module, and means for receiving and storing control data according to the reception command in the mobile equipment, and the server comprises means for determining the properties supported by mobile stations in the mobile network, and means for transferring information about the control data to the subscriber identity module of the mobile station such that the information to be transferred only includes control data relating to the properties supported by said mobile station. [0006] The invention further relates to a mobile station comprising a mobile equipment and therein a subscriber identity module for storing information on a mobile subscriber, the mobile station comprising means for receiving and storing control data. Said mobile station is characterized in that the subscriber identity module comprises means for storing a triggering condition, means for detecting the fulfilment of the defined triggering condition, means for receiving information about the control data to be transferred to the mobile station, and means for issuing a control data reception command to the mobile station based on the information received about the control data, and the mobile equipment comprises means for receiving the control data reception command from the subscriber identity module, and means for receiving and storing control data according to the reception command in the mobile equipment. [0007] The invention still further relates to a server comprising means for establishing a connection to a mobile station in a mobile network. Said server is characterized in that the server further comprises means for determining the properties supported by mobile stations in the mobile network, and means for transferring information about the control data to a subscriber identity module in the mobile station such that the data transferred only comprises control data relating to properties supported by said mobile station. [0008] In the GSM system (Global System for Mobile Communications), a mobile subscriber is identified based on the use of a SIM card (Sub- scriber Identity Module). The SIM card is used in mobile equipment and it comprises information required for identifying the user and encrypting radio traffic. The intention is not to restrict the invention to a GSM type of subscriber identity module, although the description deals with the GSM system by way of example. Instead of a detachable unit, a subscriber identity module that is a fixed part of the mobile equipment can also be used. [0009] The invention is based on the idea of the subscriber identity module sending a command providing a chance to update control data, to the mobile equipment. The subscriber identity module itself, the user of the mobile station or a network operator may trigger the issuing of the command. Based on the command, the mobile equipment may retrieve the updates from a net- work server or the SIM card of the mobile station in case the control data to be changed are not included in the command. Finally, the mobile equipment stores the new control data in the right place. [0010] The most significant advantages of the method, mobile system, mobile station and server of the invention are thus that the subscriber identity module or the SIM card manages and controls the update of the control data. This allows a user to easily make his special settings in the mobile station when moving the SIM card from one mobile equipment to another. In addition, a network operator may easily and fast update the control data or settings of a mobile station via the subscriber identity module. [0011] In an embodiment of the invention, information is transferred from the mobile equipment to the subscriber identity module about the properties the mobile equipment supports, i.e. the allowed control data or set values to be transferred to a mobile station. The subscriber identity module is able to forward this information to the network, and only information about an update of said control data is transferred to the mobile station. If the properties of a mobile station are reported as mentioned, a network server does not have to know the properties of different mobile stations beforehand. [0012] In a second embodiment of the invention, all control data are included in a control data reception command. This is the simplest way to transfer control data to the mobile equipment and it operates well particularly when the amount of data to be transferred is small. [0013] In a third embodiment of the invention, the information required for retrieving control data from the subscriber identity module is included in a control data reception command. In this case, all control data to be trans- ferred are transferred to the subscriber identity module, but they are not included in an SM command because of the large amount of data, for example. [0014] In a fourth embodiment of the invention, information required for retrieving control data from the server in the mobile network is included in a control data reception command. In this case, the control data is not at all transferred to the mobile station beforehand, whereby the memory is not un- necessarily loaded. In this case, the command only includes e.g. an address or a file name enabling the mobile equipment to retrieve the data from the network. [0015] In a fifth embodiment of the invention, the means for detecting the fulfilment of the triggering condition comprise means for receiving a control data update selection performed with the mobile station. This means that the user is able to select the moment when he updates the control data, controlled by the identity module. [0016] In a sixth embodiment of the invention, the means for detecting the fulfilment of the triggering condition comprise means for receiving a command sent by a network operator. In this case, the network operator decides when control data are updated in the mobile station and transfers then to the subscriber identity module information about the control data to be transferred to the mobile station. [0017] In a seventh embodiment of the invention, the means for de- tecting the fulfilment of the triggering condition comprise means for detecting that the mobile station has moved from the area of one network to the area of another network. This might mean for example that when a visiting mobile station arrives in Finland, the subscriber identity module gives, in a command, the mobile equipment the chance to retrieve settings relating to Finland to the mo- bile station. [0018] In an eighth embodiment of the invention, the means for detecting the fulfilment of the triggering condition comprise means for detecting the expiration of a prescribed time. If new control data are to be received fast to the mobile station irrespective of the user's choices or the mobile station's movements, reception commands issued at given intervals may prove useful. [0019] In a ninth embodiment of the invention, the server comprises a list of mobile station types used in the mobile system, the list indicating the properties of the mobile stations and the control data allowed to be received. In this case, the mobile equipment does not have to separately transfer informa- tion via the subscriber identity module to the network regarding the properties the mobile equipment supports, but the server is able to identify the mobile station type and, based thereon, find out which control data or set values are allowed. [0020] The preferred embodiments of the method, mobile system, mobile station and server of the invention are disclosed in the attached de- pendent claims. [0021] In the following, the invention will be described in detail by way of example with reference to the accompanying drawings, in which Figure 1 is a flow diagram of the method of the invention, Figure 2 is a block diagram of a mobile station of the invention, and Figure 3 is a signalling diagram of the steps of the method of the invention. [0022] Figure 1 is a flow diagram of the method of the invention. In step 1A, a control data reception command is specified for a mobile station, and a subscriber identity module can use the command to send SM com- mands to mobile equipment. The command may resemble e.g. the SEND_SHORT_MESSAGE command in the ETSI GSM 11.14 standard. In step 1B, information is transferred from the mobile equipment to the subscriber identity module indicating that the mobile equipment supports change and reception of control data. This information may also be added to e.g. a TERMI- NAL_PROFILE command, which is also specified in the ETSI GSM 11.14 standard. Information about the properties the mobile equipment supports, i.e. which control data and set values the mobile station can receive may also be added to this command. In step 1C, a triggering condition is specified for changing the control data, and the condition is stored in the subscriber identity module. After this, the subscriber identity module has to monitor when the triggering condition is fulfilled. Examples of triggering conditions are: the mobile equipment is switched on, the user of the mobile station decides to update control data, the network operator sends a command to change the control data, the mobile station moves to the area of a new network or other events are detected in the network. The expiration of a prescribed time may also be used as a triggering condition. In step 1 D, the triggering condition is found to be fulfilled. As a result, in step 1 E, information about the control data to be transferred to the mobile station is transferred from the network to the subscriber identity module. This information may include the control data to be changed or sufficient information for retrieval of the control data from the network. [0023] For a mobile station, the control data changeable in the mobile equipment include for instance: colour, brightness and size of display ringing tones profiles user settings in WAP interface colour of cover modifying telephone menu in accordance with operator/user settings settings of software loading settings of accessories passwords, user name for programs prices of calls, price conditions roaming statuses for different services group communication settings (calls, e-mail, sms, etc.) settings relating to security properties certificates including public keys used in encryption [0024] In step 1 F, a control data reception command is given from the subscriber identity module to the mobile equipment, i.e. the mobile equipment is provided with the option to change the control data or settings. The command may include the control data to be changed or sufficient information for retrieving the control data from the subscriber identity module or from a server in the mobile network. If the user of the mobile station decides to accept the change in the control data, the control data are retrieved to the mobile station or the control data included in the reception command are received. In step 1 H, the changed control data are stored in the right places in the mobile station. [0025] Figure 2 is a block diagram of a mobile station of the invention. The figure only shows the parts of a mobile station relevant to the invention. The mobile station MS shown comprises mobile equipment ME and a subscriber identity module SIM. The ME further comprises an operating system (OS) 21 , necessary software 22 and at least one memory means 23. The SIM serves to manage and control the change in control data. The SIM commands the MS to change, i.e. retrieve, receive and store control data. The operating system 21 communicates with the SIM, i.e. for example receives sig- nals from the SIM and forwards commands to suitable software 22. The software block 22 retrieves and stores the data, for instance. In retrieving the data from a server 25 in a network 24, the software block 22 may use different transmission links, such as a radio link, a cable or a Bluetooth link. A memory block 23 denotes the places in the MS, wherein the control data or set values are stored. [0026] As distinct from the terminology used in the example of Figure 2, the OS block 23 may also comprise a software component, which is not an operating system of the MS, but executes the above-described functions. [0027] Figure 3 is a signalling diagram of the steps of the method of the invention. In step 1 , the mobile equipment states, e.g. in a TERMI- NAL_PROFILE command, that it supports changing the control data. Step 2 is not entered until the triggering condition is fulfilled and information about the control data to be changed is transferred to the SIM. In step 2, the SIM gives a control data reception command, i.e. requests that the ME start to update the control data. In the command, the SIM indicates the control data to be updated and from where they are to be retrieved. In step 3, the OS directs the command to the necessary software, which may also be part of the OS of the ME. In step 4, the control data are updated by means of the software e.g. by retrieving the control data from a server in the network of the network operator using the WAP (Wireless Application Protocol). The control data are then stored in the ME. Finally, in step 5, an acknowledgement of successful control data update is transferred to the SIM. [0028] As distinct from the example of Figure 3, the reception command in step 2 may also include the control data, and thus they do not have to be separately retrieved from the network. A third alternative would be for the reception command to have included the necessary information for retrieving the control data from the SIM. Both solutions require that all control data be transferred to the SIM once the triggering condition is fulfilled. [0029] It is to be understood that the above specification and the related figures are only intended to illustrate the present invention. Different variations and modifications of the invention are apparent to those skilled in the art, without deviating from the scope and spirit of the invention disclosed in the attached claims.
