Abstract
The present disclosure relates to a system for attempting to establish a connection between a mobile phone and a virtual node of a cellular network. The system includes the virtual node that is configured to be switchable such that the virtual node is switched off and on in a defined manner. The virtual node is configured to automatically change at least one cell parameter each time the virtual node is switched off and on. Further, the present disclosure relates to a method of attempting to establish a connection between a mobile phone and a virtual node of a cellular network.
Claims16
A system for enhancing the catching performance in a cellular network, the cellular network having one or more nodes, the system comprising:
- a virtual node having one or more cell parameters, the virtual node configured to be switched off and then switched on in a defined manner, wherein the virtual node is configured to automatically change at least one cell parameter of the one or more cell parameters each time the virtual node is switched off and then switched on to cause the virtual node to appear as a physically different node in the cellular network each time the virtual node is switched off and then switched on due to the changed at least one cell parameter;
- a mobile phone having a memory for storing a blacklist thereon, the mobile phone configured to attempt to establish connection with the virtual node as long as the virtual node does not appear on the blacklist, the mobile phone configured to transmit location information to the virtual node when attempting to establish connection with the virtual node;
- an International Mobile Subscriber Identity catcher associated with the virtual node, the International Mobile Subscriber Identity catcher configured to interrogate the mobile phone, thereby obtaining the location information of the mobile phone,
- wherein the virtual node is configured to transmit a connection attempt reject signal to the mobile phone, the mobile phone placing the virtual node on the blacklist based on a value of the at least one cell parameter of the virtual node that is associated with the reject signal, and
- wherein once the value of at least one cell parameter of the virtual node is automatically changed to a new value via the virtual node being switched off and then switched on, the mobile phone is capable of attempting to establish connection to the virtual node having the new value of the at least one cell parameter so that the International Mobile Subscriber Identity catcher again interrogates the mobile phone and thereby obtains updated location information of the mobile phone.
A method for enhancing the catching performance of a cellular network, the cellular network having one or more nodes, the method comprising:
- interrogating a mobile phone by an International Mobile Subscriber Identity catcher that establishes a virtual node, thereby obtaining location information of the mobile phone, the mobile phone having a memory for storing a blacklist thereon;
- transmitting a connection attempt reject signal to the mobile phone, the mobile phone placing the virtual node on the blacklist based on the at least one cell parameter of the virtual node that is associated with the reject signal;
- switching off and then switching on the virtual node of the cellular network in a defined manner;
- automatically changing at least one cell parameter of the virtual node when said virtual node is switched off and then switched on, wherein the virtual node appears as a physically different node after the virtual node is switched off and then switched on due to the changed at least one cell parameter, wherein the automatic change of the at least one cell parameter is derived from information associated with at least one of a radio access technology standard or neighboring real cells of the cellular network;
- and thereafter
- attempting, by the mobile phone, to connect to the virtual node having the changed at least one cell parameter so that the International Mobile Subscriber Identity catcher again interrogates the mobile phone and thereby obtains updated location information of the mobile phone.
