Abstract: A hierarchical cellular network system having a core and comprising a plurality of nodes, wherein at least one node comprises a relay; and wherein at least one relay includes: a tunneling sub-system; a backhauling link subsystem interfacing between the tunneling subsystem and a node which is closer to the core than the relay; and a base station subsystem, interfacing between the tunneling subsystem and a mobile station or a node which is further from the core than the relay, wherein the tunneling subsystem is operative to perform the following, on data arriving from a base station subsystem belonging to another node from among the plurality of nodes: collecting the data; and encapsulating the results to be sent in an individual session into packets and sending the packets to the Backhauling Link Subsystem.

Abstract: A method for converting a conventional cellular network e.g. having nodes equipped with conventional modems operating in accordance with a cellular communication protocol e.g. LTE and storing first orthogonal sequences, into a private cellular network, including coupling an (e.g. external) device to only nodes sought for the private cellular network, the device storing second orthogonal sequences not hard-coded in the modems, the device storing a one-to-one correspondence enabling translation of each second orthogonal sequence, to one of the first sequences. at least when in a private network supporting mode, a device associated with a transmitting node sought for the private network, uses a processor to determine which first orthogonal sequence is being used, translate that sequence using the one-to-one correspondence into a second orthogonal sequence, and use the translated sequence to transmit a synchronization signal.

Abstract: A mobile communication network system operative in conjunction with a core network including a core device and at least one static base station includes a plurality of base stations. The system further includes a population of mobile stations communicating via antennae with the base stations. The base stations include at least one moving base station which communicates via antennae with the mobile stations and includes base station functionality and a first radio manager and mobile station functionality all co-located with the base station functionality. The base station functionality has a physical back-connection to the first radio manager. The first radio manager has a physical connection with the mobile station functionality. The mobile station functionality communicates via antennae with at least one selectable static base station. The information used to determine whether to reject includes the location of the moving base station and statistics regarding measurements of link quality.
