    operator that the subscription chooses to support that technology.
    Problem identified is that a user of the mobile services can not control the choice of operator for optimization of the following parameters: The problem 1 is that operator C, D and E support the technology but B does not support the technology if the subscription from operator A roam to B and the application will not work. Since the existing roaming logic that exists in the operators' networks and SIM cards does not take into account support for different technologies, the subscription will remain with operator B.
    Problem 2 is that operators have different pricing of their services. Assume that the original subscription A by chance roams to operator C, which means that the service will work, but operators D and E are significantly cheaper than C and a logical choice should be operator D or E.
    Problem 3 is that operators have different coverage areas for strategic reasons.
    Assume that operator D covers 95% of the country, while operator E covers only 50% of the country. If then the cost of the service is the same for both operators, the logical choice of operator is of course operator D. But with the existing roaming logic, it is random which operator the original subscription chooses.
    Virtual operators will most likely solve the problem that their subscriptions will only be allowed to roam to operators that support the different technologies, which solves problem 1 but problems 2 and 3 remain.
    Assume that virtual operators select only one operator in each in each country to get around the roaming problem, the disadvantage of that solution is if the selected operator service goes down then the application will not work.
    The problem of insufficient roaming technology became clear when trucks were equipped with devices for monitoring certain transports where the cargo space was to be sealed and when it was desired to follow the truck's physical movements between a supplier in one country to a recipient in another country.
    DESCRIPTION OF THE INVENTION The present invention solves this problem of finding an operator who provides services that handle the data communication, eg machine to machine, by means of a communication services platform described in the present application. The platform is dynamic and independent of the form of communication.
    If the platform is equipped with a local network on the vehicle, cameras, alarm sensors, other detectors, meters that are desired can be monitored. In the same way, position data can be forwarded if a GPS receiver is connected to the network.
    The platform's software takes care of roaming for data services and then specifically communication of data to data, in mobile networks between countries and operators.
    It is common for goods to be transported by truck. The value and properties of the goods may be of such a nature that the transport company wishes to monitor the transport. The truck can then be equipped with the platform described in this application, a (mobile data unit), which is connected with various modules such as a telephone module, to transmit the parameters to be monitored, GPS module for continuous tracking of the transport. When country borders are crossed, the range of operators often changes, but today's roaming algorithms have been optimized for voice communication, but the embodiment of the algorithm described in this patent preferably handles data communication, i.e. machine to machine in an optimal way for this communication.
    Transport companies may, for example, want to monitor if and when the cargo space has been opened for tracking of missing goods. Sensors in the network that register door openings or if so-called seals are broken, this can be monitored for time and place.
    Furthermore, the mobile data unit can receive other information of importance for sending to selected receiver. You can measure the mileage for service ordering when the car is expected to reach a service unit, measure the vehicle's fuel consumption and suggest refueling at a suitable fuel depot with agreed suppliers. Goods transport often takes place with towing vehicles equipped with a trailer and a detachable trailer. For transport companies with large quantities of vehicles, there is a problem with 4 keeping track of where the trailers are. As they are separated from the towing vehicle and its driver, they become anonymous and often difficult to know the physical location of. These trailers can be equipped with the described mobile data unit defined in this patent containing GPS module and voltage backup when the towing vehicle has left the trailer, the transport company can easily track and know where the unit is located. Furthermore, driver change and driving times can be registered when desired.
    Transport of certain goods may require continuous or certain monitoring of temperature, eg chilled goods.

    DETAILED DESCRIPTION Description of the platform.
    The platform can be described simply in Figure 1 as a modular electronic device with where modules can be selected for the unique needs an application may need. The platform can contain, for example, processor (1) memories in different designs such as RAM (2) and flash (3), GPS module (4) ethernet (5), power supply (6) various digital and analog inputs. The software contains the unique algorithms that are crucial to the function described in this patent application.
    An example and description of a mobile application is given in Figure 2.
    A mobile data device (7) moves out of the coverage area of the most recently used system and operator and interruptions in the mobile data service are identified by the software (8) - The algorithm for system and operator independent roaming is activated to retrieve mobile data session for continued IP (12) communication from / to the mobile data device (7).
    The algorithm begins by identifying available systems and operators (10).
    The algorithm uses both the centrally (from server) downloaded configuration parameters (11) to make selection based on available systems / operators but also the local empirical parameters from previous trials (9), and selects the highest priority system and operator.
    The algorithm makes one or more attempts (configurable parameter) to establish new mobile data session against selected system and operator.
    If the session cannot be established, the algorithm selects the next system and operator in order of priority and repeats step 5 until the mobile data session has been established. All of these attempts to establish successful and unsuccessful sessions will be used to update the empirical information stored locally in the mobile data device and will be used in future attempts to establish mobile data sessions from this location.
    Figure 3 shows an overview of the entire flow chart for an algorithm.
    The algorithm for selecting an operator when roaming for mobile data service consists of two parts: o A configuration part. It consists of a list of operators downloaded from the server to the mobile data device. The list has the following fields: - Operator code. For example, Mobile Network Code (MNC) in the GSM case - Barrier flag. A flag indicating whether the use of this operator is permitted.
    Weighting measures. A decimal value (integer) used in the self-learning algorithm to weight the priority of a particular operator.
    The mobile data unit uses this information to determine in the self-learning part whether an operator may be used or not. Furthermore, the weighting measure is used to control the mobile data unit to use certain operators to advantage, as it may be felt in advance that a certain operator in a country has a better coverage or lower cost.
    A self-learning part. It consists of an additional list that is created dynamically and built up as the mobile data unit succeeds or fails with each attempt at mobile data roaming when changing operator. Each time the mobile data unit is to establish a mobile data session, which occurs at its restart or has lost the mobile data service, it is checked which operators are available in the relevant area (by asking its mobile data module). The available operators are added to the dynamic list, if they are not already there. Before the operator is added to the list, it is checked in the configuration list downloaded from the server that the operator is allowed to be used and the weighting measure is further copied into the dynamic list.
    Then the operator whose priority is in the dynamic list is retrieved. The mobile data unit then attempts to establish a mobile data session with the selected operator. If it fails to connect to the operator or set up a session, the priority of the current operator is calculated with the weighting measure. In this way, the priority of the dynamic list will contain a self-learning function, where the priority value contains an empirical measure of how well an operator works in a particular country.
    The dynamic list therefore has the following fields: - Operator code - Barring flag - Weighting measure - Priority A feature that is of great importance for mobile applications is the ability to limit the amount of power that the mobile data unit consumes in situations when it uses battery as the only power source. The function is based on two (configurable) levels being downloaded from the server indicating: o voltage level to start the mobile data unit if it has gone down in power saving mode o voltage level to go down in power saving mode The mobile data unit shall, if this function is activated in that configuration retrieved from server, continuously monitor the voltage level from which it receives its supply voltage. When the supply voltage falls below the level specified in the configuration retrieved from the server, the mobile data unit shall notify the server that it is going down in power save mode. Thereafter, all power consuming functions should be turned off on the mobile data unit (eg main processor, mobile module, other interfaces) and only a minimal amount of components should be allowed to be energized. These components are necessary to be able to monitor voltage levels and alarm inputs. Furthermore, these components are responsible for restarting all the essential functions of the mobile data unit.
    When the mobile data unit has gone into power save mode, it is only allowed to restart: o The voltage level exceeds the (start-up) level configured (previously retrieved from server) o An alarm is activated on one of the active alarm inputs on the mobile u data unit o One in advance configured timer function (60 seconds up to year interval) activate a temporary start If the mobile data unit is started up due to an alarm activated, the alarm must be sent to the server and the alarm is acknowledged, the terminal must return to power save mode again.
    If the mobile data unit is started up by timer function, then the mobile data unit should announce its position (alternatively only announce its existence if position indication is missing) and then return to power saving mode again. The timer interval to be used is downloaded from the server and can be configured between 60 seconds up to 365 days.
    Another feature that is of great importance for mobile applications is the ability to send alarms with position information. The alarms must be able to be activated based on different types of alarm sensors such as door sensors in trucks / trailers, wireless alarm buttons for personal safety, permanently mounted alarm buttons, level sensor, etc.
    This means that the mobile data unit must support a set of alarm inputs and manage activation and reset of these. Furthermore, the mobile data unit shall offer a function to be able to send these alarms with position indication via the mobile data channel (from GPS receiver built into the mobile unit) and handle acknowledgment messages from the receiving party (server).
    In order to always be able to ensure on the receiving side that the mobile unit is active and has not been subjected to any sabotage or interruption of operations, the mobile data unit must also send a connection monitoring message with position indication continuously at a predetermined interval. In the absence of these messages, the receiving device (server) can trigger a connection alarm, where the last known position and time can be specified in the alarm.
    When equipped with these two features, the mobile data device can be used for a variety of mobile security applications.
    Configuration of these two functions (alarm inputs and connection control message) must be possible from the receiving unit (server) and updated via the data channel of the mobile data unit. Figure 4 shows the installation of the mobile data unit (16) in an application with a trailer. Antennas (14) for communication and GPS are located on the roof of the truck. Sensors for detecting the door opening (15) give a signal to the data unit (16) for events related to the opening.
    GPS receivers, other electronics and power supplies (17) are integrated in a device box (18) together with the mobile data unit (16).
    Figure 5 shows how the mobile data unit (19) is electrically connected together with the battery monitor (20) and battery (21).
    The concrete application described in this document describes a need for a communication between a vehicle and its principal in a reliable manner without interruptions caused by current shortcomings in the range of services.
    The application is by no means limited to this physical application but is described solely by means of this how the invention can be practically used.
    The invention can be used on land, at sea and in the air where the same phenomenon occurs when the coverage areas for different actors are exceeded.
