Definitions

  • the present invention relates to a protection at network element location, especially at a base station of a telecommunication network or at a data center.
  • a system for protecting physical access through a lock mechanism to a network element in a telecommunication network comprising:
  • the mechanical lock of the network element for example a base station, is automatically inhibited once the communication is established with the operator network. In this manner operator will be able to re-activate the mechanical lock if on-site maintenance is needed. If the network communication is broken between operator and base station, the mechanical lock is by default active.
  • the system prevents breaking on network element like base station by forcing the door lock resulting in many less alarm for operators, hence a reduction of maintenance costs.
  • preventing open doors will avoid at least the following problems:
  • the lock mechanism like the door cylinder sash lock is visible and easy to force with a screw driver.
  • the process to force the base station will be really more complicated.
  • means for inhibiting the lock mechanism is an electromagnet that is linked to the lock mechanism and cooperates with a metallic object preventing the lock mechanism to work.
  • the electromagnet is powered on by the system to cooperate with the metallic object.
  • system is connected to a device able to command the system and to attribute the value of the software parameter.
  • the network element is a base station or a data center.
  • physical access to the network element is access to a room inside the network element where hardware or electronic devices are located.
  • a further object of the invention is method for protecting physical access through a lock mechanism to a network element in a telecommunication network, comprising the following steps executed in a system coupled to the lock mechanism:
  • the invention relates further to a computer program adapted to be executed in a system for a physical access protection of a network element in a telecommunication network, said program induing instructions which, when the program is executed in said system, execute the steps of the method of the invention.
  • a network element NE included in a telecommunication network TN is associated with a lock protection system LPS including an electromagnet EM and an interface INT.
  • the lock protection system LPS is a mechanical system whose function is to protect or inhibit physical access to the network element NE.
  • the lock protection system LPS is coupled to a lock mechanism allowing physical access to the network element NE, more specifically to a room where at least a communicating device of the network element is located.
  • the lock protection system LPS is connected to a command device CD, that can be a server or any communicating device, able to command the lock protection system LPS.
  • the electromagnet EM is linked to the lock mechanism of the network element and cooperates with a metallic object in order to inhibit or not the lock mechanism.
  • the metallic object prevents the lock mechanism to work, for example by impeding access to the lock mechanism by human.
  • the lock mechanism can feature various ways to access it as non limited examples: key hole, mechanical combination lock, or electronic keypads, that all need to be hidden or inhibited so that a malicious intruder will not be able to use them.
  • the interface INT checks signal information about whether the network element NE is connected or not to the telecommunication network TN.
  • the signal information comes from the network element itself.
  • the network element comprises also an interface to communicate with the lock protection system LPS.
  • the signal information comes from the command device CD which retrieves information if the network element NE is connected or not to the telecommunication network TN from an entity of the telecommunication network.
  • the lock protection system LPS is not active, in order to cover cases where the network element is powered-off or has a broken connection with the telecommunication network.
  • the lock protection system LPS is automatically deactivated in case of a power-off situation.
  • the lock protection system LPS is activated if two conditions are satisfied: a connection with the operator of the telecommunication network and a feature activated by software. Once the electromagnet is power on, the lock is inhibited.
  • the electromagnet EM is controlled by the lock protection system LPS that follows the process according to FIG. 1 comprising steps S1 to S4.
  • step S1 the electromagnet EM is not powered, meaning that lock protection system LPS is not activated.
  • the interface INT of the lock protection system LPS checks information about whether the network element NE is connected or not to the telecommunication network.
  • step S3 If the network element NE is connected to the telecommunication network, the process continues with step S3, otherwise the process goes back to step S1.
  • the information checked by the interface INT at step S2 can come from the network element itself or from the command device CD connected to the lock protection system LPS.
  • the interface INT of the lock protection system LPS checks information about a value of a software parameter SP indicating if the lock mechanism should be inhibited or not.
  • the software parameter SP is the following parameter DOOR_LOCK_INHIBIT being a Boolean parameter, having a state with value of "1" meaning the lock mechanism should be inhibited and another state with value of "0" meaning the lock mechanism should not be inhibited.
  • step S4 If the value of the software parameter SP is "1”, the process continues with step S4, otherwise if the value of the software parameter SP is "0", the process goes back to step S1.
  • the information checked by the interface INT at step S3 comes from the command device CD that is connected to the lock protection system LPS and attributes the value of the software parameter.
  • the electromagnet EM is powered on to cooperate with a metallic object, meaning that lock protection system LPS is activated to inhibit the lock mechanism and protect physical access to the network element NE.
  • physical access to the network element NE it is meant for example access to a room inside the network element where hardware or electronic devices are located, like a server.
  • the lock protection system LPS is thus activated as the both conditions are satisfied: the network element NE is connected to the telecommunication network and software parameter SP at state with value of "1".
  • a metallic plate can be lifted thanks to a knob only if the electromagnet EM does not lock this metallic plate, i.e. the electromagnet is not powered.
  • the electromagnet EM is powered on and the metallic plate protects the keyhole that is not accessible, the metallic plate being attracted by the electromagnet.
  • the electromagnet EM is powered off and the metallic plate lets the keyhole accessible, the metallic plate being free to move.
  • the electromagnet EM does not aim to protect the lock cylinder, but to inhibit the multi-lock mechanism. Once inhibited, the lock cylinder can be turned but it does not act on the multi-lock mechanism. Opening the door can only be done if the electromagnet EM is powered off. Then, the multi-lock mechanism is released and engaged with the lock cylinder.
  • the electromagnet EM is powered on, the spring around it being compressed, and metal moving part of the multi-lock mechanism is attracted by the electromagnet and moved away from the lock cylinder.
  • the lock protection system LPS may also be used directly on a door lock mechanism itself, for example in the case when the room containing the network element to be protected is already inside a secure building. In this case there is no need to have a specific key or combination to know to enter the room: an operator agent can enter the room when the network element is powered off, when it is not connected to the operator network. Otherwise the agent has to modify the value of the DOOR_LOCK_INHIBIT software parameter to "0" and the door will unlock.
  • the lock protection system LPS solution is lighter and cheaper than a security door:
  • the lock protection system LPS is also very simple to add to an already installed equipment (possibly without a service interruption).
  • the invention described here relates to a method and a system for a physical access protection of a network element in a telecommunication network.
  • the steps of the method of the invention are determined by the instructions of a computer program incorporated in a system such as the lock protection system LPS.
  • the program includes program instructions which, when said program is executed in a processor of the system the operation whereof is then controlled by the execution of the program, execute the steps of the method according to the invention.
  • the invention applies also to a computer program, in particular a computer program on or in an information medium readable by a data processing device, adapted to implement the invention.
  • That program may use any programming language and be in the form of source code, object code or an intermediate code between source code and object code, such as a partially compiled form, or in any other desirable form for implementing the method according to the invention.
  • the information medium may be any entity or device capable of storing the program.
  • the medium may include storage means or a recording medium on which the computer program according to the invention is recorded, such as a ROM, for example a CD ROM or a microelectronic circuit ROM, or a USB key, or magnetic recording means, for example a diskette (floppy disk) or a hard disk.
