Abstract: A method is disclosed for determining an appropriate transmit power of a cell based on a desired coverage distance, comprising: initializing, at a cell, a cell reference signal transmit power at a high power level; broadcasting a cell signal power measure to require a high signal power level for user devices attempting to connect to the cell; progressively lowering the cell signal power measure at the cell; broadcasting the lowered cell signal power measure; deriving a plurality of user equipment (UE) attach request distances based on a plurality of propagation delay statistics derived from UE attach requests received at the cell; comparing the plurality of UE attach request distances against a maximum distance to obtain a number of UE attach requests received from UEs physically located beyond the maximum distance; and setting the cell reference signal transmit power based on the number of UE attach requests received from beyond the maximum distance, thereby iteratively determining an appropriate cell reference signal transmit power based on the maximum distance and on UE attach requests received at the cell.

Abstract: Systems and methods for an in-vehicle base station are described. In one embodiment, a method is disclosed, comprising: broadcasting, using the first access radio, the cellular access network at a first power; transmitting the location of the mobile base station to the cellular network; detecting, at the processor, a transition of the mobile base station from a stationary state to a moving state; reducing, at the first access radio, a transmit power of the cellular access network while in the moving state for disabling the cellular access network outside the vehicle; and increasing, at the first access radio, the transmit power of the mobile base station when exiting the moving state.

Abstract: In this invention, we disclose methods of establishing a cellular network having backhaul flexibility, comprising, establishing, at a first cellular base station, a first connection with a core cellular network; establishing, at the first cellular base station, an inter-base station connection with a second cellular base station for relaying traffic from the first and the second cellular base stations to the core cellular network, the second cellular base station having a second connection with the core cellular network; determining, at the first cellular base station, if the quality of the first connection falls below a threshold parameter; and terminating, at the first cellular base station, the first connection in favor of the second connection if the quality of the first connection falls below the threshold parameter.

Abstract: In this invention, we disclose methods directed toward integrating an ad hoc cellular network into a fixed cellular network. The methods disclosed herein automate the creation and integration of these networks. In additional embodiments, we disclose methods for establishing a stand-alone, ad hoc cellular network. In either of these implementations, we integrate or establish an ad hoc cellular network using mobile ad hoc cellular base stations configured to transmit and receive over a variety of frequencies, protocols, and duplexing schemes. The methods flexibly and dynamically choose an access or backhaul configuration and radio characteristics to optimize network performance. Additional embodiments provide for enhancing an existing network's coverage as needed, establishing a local network in the event of a loss of backhaul coverage to the core network, and providing local wireless access service within the ad hoc cellular network.

The identifier may be an international mobile subscriber identity (IMSI). The filter may be a whitelist containing a plurality of IMSIs to be granted service or a blacklist containing a plurality of IMSIs to be denied service, the service request may be a Long Term Evolution (LTE) attach request, and the method may further comprise forwarding the message from the first UE to a first mobility management entity (MME) in the first core network.

Abstract: In this invention, we disclose methods for enabling ad hoc cellular base station functionality within a user equipment when the connection quality between a base station and the user equipment is limited or nonexistent. These methods include measuring a connection quality between a user equipment and its serving base station. If the connection quality is below a threshold, the user equipment can enable its internal ad hoc cellular base station functionality. This is done by running a software within the user equipment that (a) checks the connection quality periodically, and (b) enables ad hoc cellular base station functionality of the connection threshold dips below a certain value. In one embodiment, that threshold could be the same threshold value that a user equipment would use if it were making a decision to handoff to another base station based on poor connection quality.

Abstract: A wireless configuration network may be provided by a Wi-Fi hotspot active at the wireless access station. The Wi-Fi hotspot may be connected to by a wireless network-capable device, such as a tablet computer, e.g., an Apple iPad, or a Wi-Fi enabled smartphone, e.g., an Android or Apple iOS device. This allows a technician to stand on the ground below the wireless access station but still have access to various configuration features of the wireless access station. The wireless configuration network may also be referred to herein as a “debug SSID” or a “debug access point.”
