Definitions
- the invention relates to a method for computer-assisted operation of an autonomous network with a plurality of autonomous terminals, which have at least one programmable transceiver and which are designed to autonomously identify available frequency ranges for a communication connection and to use them by reconfiguring their programmable transceiver.
- the invention further relates to a network having a plurality of autonomous terminals which have at least one programmable transceiver and which are designed to independently identify available frequency ranges for a communication connection and to use them by reconfiguring their programmable transceivers.
- transceiver artificial word from the English words transmitter and receiver
- the transceiver is responsible for transmitting and receiving signals over a transmission medium, and more particularly for feeding and dropping the signals into / out of the medium.
- a terminal is an object, eg a computer, mobile computer, telephone or mobile telephone, which is connected to a network termination of a network, for example a data or telecommunication network.
- the connection can be direct, ie wired, or indirect, over a radio link.
- the development of wireless networks is characterized by increasing flexibility of frequency band use. This goes hand in hand with the development of end devices that can largely autonomously use radio or radio technologies and frequency bands within the framework of prescribed regulatory requirements.
- An example of such devices which have a largely autonomous operation when switching between radio technologies and frequency bands so-called "Cognitive Radios", based on the use of recon- figurierbaren terminals (so-called SDR terminals) basie ⁇ ren.
- Control is provided by a so- ⁇ -called radio resource management. This is done, for example, in the standard UMTS (Universal Mobile Telecommunications System) by a central unit, which is referred to as RNC (Radio Network Controller). Mobile terminals are controlled according to this standard by the network itself ge ⁇ .
- UMTS Universal Mobile Telecommunications System
- RNC Radio Network Controller
- the invention is based on the recognition that the dynamics of autonomous terminals can lead to collective effects. Such dynamics are given, for example, in the decision and implementation of mode changes. As a result, such dynamics can significantly affect the operation, especially of cellular radio networks.
- cellular networks can be prepared by the simultaneous change a larger number of terminals to a particular base station of the network to interference of the operation of the network tier ⁇ ren.
- the invention is therefore based on the idea of imposing such a dynamic limitation of the behavior of the terminals. Since static constraints are considered inadequate, a dynamic limitation of the behaviors of the terminals, which can be adapted to the particular situation, is proposed. In this case, a continuous observation of the network is carried out so that suitable countermeasures can be deduced and imposed on the terminals when unwanted conditions occur.
- the inventive method for the computer- ⁇ aided operation includes a network having a plurality of autonomous devices, which have at least one programmable transceivers and which are adapted to independently identify for a communication connection available frequency ranges and to use by reconfiguring their programmable transceiver the steps of :
- the set of rules may comprise a single or a multi ⁇ number.
- the proposed method ensures that terminals operating autonomously within the network utilize resources of the network in a manner that enables specified goals of an operator of the network concerning the operation of the network to be achieved.
- targets which are found in system states, can be e.g. the utilization of the network, a trouble-free operation in dedicated frequency bands, the reservation of parts of certain frequency bands for certain types of use, such as emergency cases or the like.
- autonomous terminal devices are to be understood in particular as the "cognitive radios" already mentioned at the outset, which independently identify suitable available frequency ranges for their current usage context and can use them by reconfiguring their programmable transceivers.
- the inventive network in the context of the present invention is also called “Cognitive Radio Network”, as this is able to learn from a Be ⁇ observation and fall decisions regarding the modification of the rules by which the behavior of the autonomous devices is affected.
- An essential feature of the inventive method is thus to make no direct intervention in the operation of individual devices on the part of the network in which certain commands or instructions are transmitted to the relevant terminals. Instead, interventions are made indirectly via (behavioral) rules.
- the transmission is provided at least one satellite ⁇ zes of rules to the autonomous Endgerate as a further step.
- the transmission of the rules can take place actively through the network, but it can also be implemented passively, for example by means of a download initiated by the terminals.
- the autonomous terminal devices assume a target operating state and / or a destination configuration, which are derived from a usage context and usage preferences, wherein the target operating state and / or the target configuration fulfill the rules
- Usage preferences may be, for example, the preferred use of a particular frequency band, bandwidth, or service.
- the usage context is determined, for example, by tasks of the terminal to be completed.
- the primary way of working autonomous Endgerate is defined in other words by the specific for each Endgerat context of use and possibly spe ⁇ z e Warspraferenzen. This results in a target operating state and / or a target configuration, which should be due to the still be considered by the terminal rules within these rules.
- a continuous adaptation of the rules in response to certain system states of the network results when the sets of rules cause the autonomous terminals to report the network resources they use to the network.
- the data transmitted to the network here include, for example, the frequency range used, CDMA codes or interferences generated by the selected transmission power. These are just some examples of the additional payment is seek as a non-final to be ⁇ .
- the network resources used by the autonomous terminals will be transmitted continuously to the network.
- the data related to the utilized network resources transmitted by the autonomous terminals may be linked to one or more network identifiers determined by network monitoring units of the network to determine whether the actual system state of the network is different from the network state (s) set or system states.
- the network parameters or network parameters are continuously monitored. The comparison of an actual system state with predetermined system states of the network allows continuous to ⁇ fit the proposition of rules and / or setting new rules to be able to achieve the laid down system state of the network or the best possible way.
- a kind of control loop can be created, whereby ideally the Actual system state of the network can be mapped to the specified system state of the network.
- che for different portions of the network ⁇ differing sets of rules are provided to take into account the specifics of the network structure and / or use by autonomous devices.
- Autonomous terminals that move from one of the sections of the network to one of the other sections of the network can then be assigned a new set of rules.
- an optimized operation of the network can be achieved since specific properties of the network in the different sections can be taken into account.

- a characteristic of the rules of the second kind is that they must be taken into account when using the resources of the network from the terminals. Provision can be made for autonomous terminals which do not comply with the operating conditions and / or the configuration set by the rules to be excluded from the use of the resources of the network.
- the sets of rules are provided by the network, in particular a network node with network rule offering functionality.
- the sets are created of rules by the network and / or adapted.

This ensures that even with increasing configurability of network elements and terminals and the associated increasing complexity of the overall arrangement, efficient management of network resources is possible. It should be highlighted that no central unit is necessary, which takes over the control of different ⁇ lichsten network elements.
- Predefined rules are guidelines for the behavior of the terminals within the network. The rules ensure, despite higher degrees of freedom for the operation of the terminals, that the interests of the operators of the network and the other users of the network infrastructure are safeguarded.
- Another advantage is the possibility of self-configuration. Both the terminals and the networks interacting with them are largely self-configuring, each optimizing the use of their resources in accordance with predetermined conditions that exist in the networks Rules are formulated.
- the predetermined by the network rules allow an influence of the network to a ⁇ zelne Endgerate without their detailed condi ⁇ maintain or even whose internal state must be known.
