Multiple mobile cellular network (MCN) communication systems can be networked together to form a network of MCN communication systems (NOM). Each MCN communication system within the NOM can operate as an independent cellular network to provide communications between user equipment within a covered area. The MCN can be managed by a network management control center (NMCC). The NMCC can be configured generate coverage maps of the NOM and NMC system coverage areas.

A pedestrian and worker safety system, comprising: a) at least one smart wristband unit; and b) one or more machines, vehicles and/or trains, each comprising i) a communication unit comprising a wireless transceiver capable of transmitting and/or receiving at least one warning information to/from at least one smart wristband unit; and ii) a warning display unit, wherein warning information is transmitted via wireless communication between one or more machines, vehicles and/or trains and at least one smart wristband unit.

A mobile cellular network (MCN) communication system can provide an independent mobile cellular network to devices within a covered area. In addition, the MCN communication system can communicate with other MCN communication systems using a wireless standard that is similar to the wireless standard used to communicate with user equipment within the covered area. In some instances, the MCN communication system can be registered as a user equipment of another MCN communication system and/or have another MCN communication system registered with it as a user equipment.

A radio communication system includes a relay apparatus (30) connected between a base station (40) and a base control station (20) and a location information control station (10), in which: the location information control station (10) includes: a request generation unit (11) for generating a location information request including regional information of a region for which the location information is requested; and a request transmission unit (12) for transmitting the location information request that has been generated to the base control station (20), and the base control station (20) includes: a request reception unit (21) for receiving the location information request transmitted from the location information control station (10); and a request transmission unit (22) for transmitting the location information request including the regional information in the location information request that has been received to the relay apparatus (30). It is therefore possible to accurately transmit the location information request.

Methods and systems are provided for selecting a network slice to which a User Equipment (UE) can connect in the telecommunications network. A Cache Inventory Repository (CIR) stores cache associations indicating content cached at each of a plurality of Cache Network Functions (Cache NFs) and the network slice in which each Cache NR is located. A Network Slice Selection Function (NSSF) transmits to the CIR a request for cache data indicating a particular content cached in one or more network slices. The CIR determines the requested cache data based on the stored cache associations and transmits the requested cache data to the NSSF. The NSSF selects a network slice to which the UE can connect, based at least in part on the received cache data identifying the one or more network slices.

A computerized safety tracking and proximity warning method and system for personnel, plant and equipment operating both above and below the ground and moving therebetween comprising a computer adapted to receive wireless position information from transponders carried or worn by personnel, and affixed to plant or equipment via one or more wireless communication protocols to provide a seamless visual display of their relative positions whether above or below ground level or moving therebetween, and wherein an alarm is triggered to alert an operator or worker if the locations of the personnel and plant or equipment are within a predetermined and unsafe distance of each other.

A controller 13 of a radio terminal 10 performs a first switching process of switching a standby target or a connection target from a mobile communication network to a wireless LAN. The controller 13 executes the first switching process in case that: a movement state of the radio terminal 10 is determined as a first state; and a condition for performing the first switching process is satisfied over a predetermined period. The controller 13 further executes the first switching process in case that: the movement state of the radio terminal 10 is determined as a second state; an access point 200 constituting the wireless LAN is a moving access point; and the condition for performing the first switching process is satisfied over the predetermined period.

Systems, methods, and non-transitory computer-readable media can identify a set of users of a transportation system. A set of user social network profiles on a social networking system associated with the set of users is determined, each of the user social network profiles associated with user social network information. User location information is recorded for the set of users. The transportation system is revised based on the user location information.

The Aircraft Mobile IP Address System provides wireless communication services to passengers who are located onboard an aircraft by storing data indicative of the individually identified wireless devices located onboard the aircraft. The System assigns a single IP address to each Point-to-Point Protocol link which connects the aircraft network to the ground-based communication network but also creates an IP subnet onboard the aircraft. The IP subnet utilizes a plurality of IP addresses for each Point-to-Point link thereby to enable each passenger wireless device to be uniquely identified with their own IP address. This is enabled since both Point-to-Point Protocol IPCP endpoints have pre-defined IP address pools and/or topology configured; each Point-to-Point Protocol endpoint can utilize a greater number of IP addresses than one per link. Such an approach does not change IPCP or other EVDO protocols/messaging but does allow this address to be directly visible to the ground-based communication network.
