Abstract: A method for establishing a self-organized emergency mobile core in a cellular communication network, the cellular communication network having a core element. The method includes the step of storing program code for implementing core network functionality on at least one stationary network element of the cellular communication network allowing to host virtual network functionality. The core network functionality remains inactive when the core element is available. The method includes the steps of detecting an emergency event within the cellular communication network resulting in an unavailability of the core element, and starting operating the core network functionality in order to establish a self-organized emergency mobile core in response to the detected emergency event.

Abstract: There are provided a system and method of assessing latency of forwarding data packets in virtual environment. The method comprises: generating packet signatures SGD and SGA respectively for departing and arriving data packets; maintaining a first data structure comprising records related to departing packets associated with a first virtual function (VF), each record informative of SGD and registered departure time TD of a given departing packet; responsive to registering arriving time TA of a given monitored arriving packet SGA associated with a second VF, searching the first data structure for a record matching a matching condition SGD=SGA; modifying the matching record to become informative of latency ΔT=TA−TD and adding the modified record to a second data structure; and using data in the second data structure for assessing latency of forwarding packets from the ingress virtual port to the egress virtual port.

Abstract: A method for facilitating participation of an intermediary network device in a security gateway communication including: establishing a secure channel between the intermediary network device and a security gateway; transmitting a virtual machine instantiation command generated by software running in the security gateway to the intermediary network device; instantiating a virtual machine on the intermediary network device; when establishing a secure communication session between the at least one base station and the core network portion via the security gateway for the first time, establishing an Internet Key Exchange communication between the virtual machine and the security gateway and transmitting session keys from the security gateway to the virtual machine during the Internet Key Exchange communication; establishing an IPsec tunnel between the virtual machine and the security gateway.

Abstract: A method for facilitating coordinated multipoint communication providing a plurality of network interface devices for measuring synchronization accuracy in the backhaul network; creating an actual coverage map for the coordinated multipoint communication analyzing the created actual coverage map to determine whether the backhaul network is sufficient for a selected coordinated multipoint technique; if the backhaul network is not sufficient determining one or more key performance indicators creating a conditional coverage map; comparing the actual coverage map with the conditional coverage map; reconfiguring the wireless communication network if the actual coverage map does not match the conditional coverage map.
