Abstract:
A method may be disclosed in accordance with some embodiments, comprising: receiving, at a virtualizing gateway between the eNodeB and a first core network, a service request from a first user equipment (UE) via an eNodeB; applying a filter to an identifier of the UE to authenticate the UE; and forwarding, based on the applied filter, the service request from the first UE to the first core 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:
Systems and methods are disclosed for enabling a mesh network node to switch from a base station role to a user equipment role relative to a second mesh network node, and vice versa. By switching roles in this manner, the mesh network node may be able to benefit from increased uplink or downlink speed in the new role. This role reversal technique is particularly useful when using wireless protocols such as LTE that are asymmetric and allow differing throughput on uplink and downlink connections. Methods for determining whether to perform role reversal are disclosed, and methods for using role reversal in mesh networks comprising greater than two nodes are also disclosed.
Abstract:
Systems and methods are disclosed for a local evolved packet core (EPC) that interoperates with an eNodeB and a remote EPC. if it is determined that it is possible or likely that the eNodeBs may lose the connection to the remote EPC, or if a connection has been lost, the local EPC may serve as a transparent proxy between the eNodeBs and the remote EPC, identify active sessions and transparently proxy those sessions, destroy or de-allocate unneeded sessions or bearers, and download and synchronize application data and authentication credentials, such as HSS or AAA data, to provide authentication to mobile devices once offline. The use of the local EPC and/or the remote EPC may be toggled, or switched, preemptively or reactively, based on various network conditions. The remote EPC may be disconnected proactively when the local EPC determines that there is no connectivity.
Abstract:
In this invention we disclose methods for incorporating a security gateway within a wireless mesh network. In one embodiment, the wireless mesh network is a heterogeneous mesh network. In one embodiment, a gateway node, which is part of the wireless mesh network, requests a connection to the core network through a security gateway. The security gateway responds by creating an IPSec tunnel and a GRE tunnel within the IPSec tunnel from itself to the gateway node. Once the gateway node is communicatively coupled to the security gateway via secure tunneling, the gateway node sends a mesh routing protocol to the security gateway.
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:
Systems and methods are disclosed for supporting multi-point transmission. In one embodiment, a system for downlink multi-point transmission are disclosed, comprising: a first base station in radio frequency proximity to a user device and with a established control connection with the user device; a second base station also in radio frequency proximity to the user device; and a coordinating node coupled to the first and the second base station for coordinating transmissions to the first and the second base station to the user device, the coordinating node configured to: select the second base station based on selection criteria, the selection criteria including latency of each base station and perceived signal strength of each base station at the user device; and send scheduling instructions to each of the first and the second base stations to transmit data to the user device.

Abstract:
A system is disclosed for providing multicast services to mobile devices, comprising a first network node providing a radio access network to a mobile device; a second network node coupled to the first network node and providing backhaul routing for the first network node; a controller node, coupled to both the first and the second network node and to a multicast packet gateway, wherein the controller node provides a virtualized interface of a single network node to the multicast packet gateway, thereby virtualizing the first and second network nodes to the multicast packet gateway such that the multicast packet gateway may be enabled to send a multicast data stream to the first and the second network nodes via the controller node.
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.
