摘要： A packet data service node (PDSN) is formed to establish a connection with a plurality of mobile terminals by way of one or more packet control function cards or devices. A packet control function (PCF) card or device is formed to provide an interface between the packet data domain and wireless domain and further to inform a base station controller/access network controller (BSC/ANC) to block the setup and establishment of any additional communication links in a specified manner until the overload condition ceases to exist. More specifically, the PCF receives loading information from each PDSN to which it is connected and determines a composite loading factor. The PCF transmits the composite loading factor to the BSC/ANC periodically or if the loading factor exceeds a specified threshold and call blocking should be initiated for packet data calls for a select group of mobile terminals.
摘要翻译：分组数据服务节点（PDSN）被形成为通过一个或多个分组控制功能卡或设备建立与多个移动终端的连接。形成分组控制功能（PCF）卡或设备以在分组数据域和无线域之间提供接口，并进一步通知基站控制器/接入网络控制器（BSC / ANC）来阻止任何附加通信链路以特定方式直到过载状态不复存在。更具体地说，PCF从其所连接的每个PDSN接收加载信息并确定复合加载系数。 PCF周期性地将复合负载因子发送到BSC / ANC，或者如果负载因子超过指定的阈值，则应针对选择的一组移动终端的分组数据呼叫启动呼叫阻塞。

摘要： A call flow is provided in a wireless communication system (100) to enable quality of service (QoS) parameters to be retrieved and provided to a base station (102) when a wireless device (101a) requests service. The QoS parameters may include or represent a QoS profile associated with the wireless device (101a), a QoS profile associated with a user of the wireless device (101a), or a QoS policy for a session involving the wireless device. The base station (102) uses the QoS parameters to control access to the system (100) by the wireless device (101a). Another call flow is provided to transfer the QoS parameters from the base station (101a) to a packet control function (107) for storage when a packet data session associated with the wireless device (101a) becomes dormant. If the packet data session is later reactivated, the QoS parameters are provided from the packet control function (107) back to the base station (101a).
摘要翻译：当无线设备（101a）请求服务时，在无线通信系统（100）中提供呼叫流，以使服务质量（QoS）参数被检索并提供给基站（102）。 QoS参数可以包括或表示与无线设备（101a）相关联的QoS简档，与无线设备（101a）的用户相关联的QoS简档，或者涉及无线设备的会话的QoS策略。基站（102）使用QoS参数来控制无线设备（101a）对系统（100）的访问。当与无线设备（101a）相关联的分组数据会话变为休眠时，提供另一呼叫流程以将QoS参数从基站（101a）传送到分组控制功能（107）以用于存储。如果稍后重新启动分组数据会话，则将QoS参数从分组控制功能（107）提供回基站（101a）。

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
