Abstract: A plurality of radar sensors and radio units are controlled and processed by a signal processing unit (SPU). Each radar sensor receives configuration, control, power management, and calibration messages along with compressed data stream for transmission from the SPU over a multi Giga-bit interface (MGBI). Each radar sensor transmits status messages and compressed received data stream to the SPU over an MGBI. The SPU performs radar signal processing and tracking upon decompressing the data stream received from the radar sensor. Each radio unit receives configuration, control, power management, and calibration messages along with compressed frequency-domain waveform samples for each transmitter antenna port and for each component carrier configured by the SPU over an MGBI. Each radio unit transmits status messages along with compressed calibration data and compressed frequency-domain waveform samples for each receive antenna port and for each component carrier configured by the SPU over an MGBI. The SPU decompresses the frequency-domain waveform samples, and performs radio baseband signal processing including channel estimation, transmit beamforming, and receive beamforming. The SPU establishes and maintains time synchronization with each radar sensor and radio unit connected to it over an MGBI.

Abstract: Systems and methods for call localization are provided. The call localization can be provided in a radio access network by detecting a call flow between mobile node such as user equipment (UE) served by the same radio access network device. For example, a gateway can detect a call localization opportunity and the call can be localized with an evolved nodeB (eNB). The method provides for efficient routing, reporting of billing information, lawful monitoring, and mobility if one or both user equipment leave the common eNB.

Abstract: This disclosure relates to systems and methods for paging devices in a communication network. A network device providing mobility management through control messaging can be assigned a number of cell sites in a tracking area. The network device such as a mobility management entity (MME) can use a criteria or heuristic based implementation to provide a hierarchy for contacting a mobile device with a page. The criteria or heuristic based implementation can page a subset of the total number of cell sites in a tracking area and expand the subset after unsuccessful attempts to page the mobile device. The implementation can also be tailored to offer a range of options for page requests received by a network device, which can be based on such things as the application sending the page request.

Abstract: Location reporting in long term evolution (LTE) wireless networks is provided. Systems and methods are disclosed to provide support of location reporting and messaging at a mobility management entity (MME) to allow location updates to serving gateways (SGWs) and packet data network gateways (PGWs), and for the SGWs and PGWs to activate and de-activate location reporting. The MME also supports detection and communication with the LTE radio access network to provide location reporting back to the communication network. The MME and the accompanying messaging can provide location reporting including enhanced cell global identity (ECGI) and tracking area identity (TAI) information.

Abstract: Methods and systems are provided for updating the quality of service (QoS) of an IP flow in a wireless communications system. More particularly, the methods and systems provide the ability to update a QoS grant from any level of QoS to any other level of QoS, from no QoS to some level of QoS, and from some level of QoS to no level of QoS. The update of QoS can be based, at least in part, on a request being made for an updated QoS. A decision is made whether or not to update the QoS; and depending on the decision, the QoS can be updated.

Abstract: The invention is a new protocol for securing the communication link between the Home Agent and the Mobile Node. A cipher key and an integrity key are generated at a home AAA server and are also generated independently at the Mobile Node. The two keys generated at the home AAA server are transmitted to the Home Agent to secure information packets transmitted between the Mobile Node and the Home Agent. The cipher key and integrity key are used to establish a security association used for information packet transmissions. The cipher key is used to encrypt the information packets, and the integrity key is used to ensure that the contents of the encrypted message are not altered.

Abstract: Systems and methods for providing an interface to communicate policy information from a policy server to a policy enforcement point are presented. An external policy server is used to implement and provide various policies to a policy enforcement point for enforcement on subscriber sessions and traffic flows of a mobile subscriber. A policy enforcement point can request instructions from the policy server using an access-request message and receive from the policy server unsolicited instructions with a change-of-authorization message. Policies for application to a subscriber session or traffic flow are included in the message from a policy server to the policy enforcement point. Other messages such as a disconnect message are used to terminate a subscriber session.

Abstract: Systems and methods to manage network access (e.g., IPv4 and IPv6) and layer 3 mobility are provided. This can allow mobility management to be moved from a mobile node's stack to the access gateway, simplifying the stack and providing fast handoffs. The mobility management at an access gateway further allows a mobile node to keep its dynamically assigned IP address for the duration of a call session and through handoffs. The placement of access gateways in a domain of trust allows security information to be passed between access gateways in a handoff so that the security associations do not need to be re-authenticated with the mobile node. One or more of the above mobility management features can be used to provide a fast and seamless handoff for a mobile node.
