摘要： Content may be transmitted to mobile devices, in a network, using a Multimedia Broadcast Multicast Services (MBMS) multicast technique over wireless interfaces in the network. In one implementation, network elements in the network may receive feedback about the MBMS multicast transmission, where the feedback relates to a quality of the content, as received by the one or more mobile devices, or to the quality of the radio channel. The devices may determine whether to modify transmission parameters relating to the MBMS multicast transmission and may determine whether to retransmit lost data, corresponding to the content, to the mobile devices. The lost data may be retransmitted as a unicast transmission or a multicast transmission.
摘要翻译：内容可以通过网络中的无线接口使用多媒体广播组播服务（MBMS）多播技术在网络中传输到移动设备。在一个实现中，网络中的网络元件可以接收关于MBMS组播传输的反馈，其中反馈与由一个或多个移动设备接收的内容的质量或无线电信道的质量相关。设备可以确定是否修改与MBMS多播传输相关的传输参数，并且可以确定是否将与内容相对应的丢失数据重传到移动设备。丢失的数据可以作为单播传输或多播传输重传。

摘要： Disclosed examples of secure communications involve generating, by a mobile communication network device, a shared secret data having a length of M units. A first operation on groups of one of N units of a randomly generated base shared secret data and one of a plurality of secret values thereby generates a plurality of first operation results. A second operation on a select plurality of the first operation results generates a plurality of second operation results. The randomly generated base shared secret data can have a length of N units, where N is less than M. The shared secret data is constructed from at least one of the first operation results and the plurality of second operation results.

摘要： A method and system for fast setup of group Voice over Internet Protocol (VoIP) communications. The method and system provide a lower VoIP signaling overhead and a faster setup-time of group calls such as N-way audio and/or audio-video conference calls. Multi-party VoIP connections are quickly set-up over one or more virtual communications channels established between plural network devices using a session layer application, one or more group transport layer ports and a broadcast destination network address.

摘要： Packet data network (PDN) connection requests from a mobile device may be limited by the mobile device. In one implementation, the mobile device may track an amount of successful PDN connection requests issued by the mobile device over a cellular network and maintain a timer value relating to an amount of time over which the successful PDN connection requests have been tracked. The mobile device may determine an allowable number of PDN connection requests and compare the amount of successful PDN connection requests to the allowable number of PDN connection requests. The mobile device may determine, based on the comparison, whether to block a PDN connection request from being issued to the cellular network.
摘要翻译：来自移动设备的分组数据网络（PDN）连接请求可能受到移动设备的限制。在一个实现中，移动设备可以跟踪移动设备通过蜂窝网络发出的成功PDN连接请求的数量，并且维护与已经跟踪成功的PDN连接请求的时间量有关的定时器值。移动设备可以确定PDN连接请求的允许数量，并将成功的PDN连接请求的数量与允许的PDN连接请求数进行比较。移动设备可以基于比较来确定是否阻止PDN连接请求被发送到蜂窝网络。

摘要： A mobile radio communication system is disclosed in which personality information for a radio can be modified in order to permit the radio to roam from one broadcast region to another. Since each broadcast region is serviced by a different gateway, the radios within that region use particular personality information in order to communication with it. When the radios roam from one region to another, the radios request new personality information relevant to the destination region. Each radio uses local identification data to uniquely identify the radio within the system. When the radio roams, the gateway provides the radio with new local identification data relevant to the destination region. The local identification data for each radio in a given region is mapped by the gateway in a memory such that available local identification data can be re-assigned to radios that roam into the gateway region. Then, when the radio leaves the region, the local identification data that was given to the radio is de-allocated such that it is then available to another radio that roams into the region.
摘要翻译：公开了一种移动无线电通信系统，其中可以修改用于无线电的个性信息，以允许无线电从一个广播区域漫游到另一个广播区域。由于每个广播区域由不同的网关服务，所以该区域内的无线电装置使用特定的个性信息以与其进行通信。当无线电从一个地区漫游到另一个地区时，无线电请求与目的地区域相关的新的人格信息。每个无线电使用本地识别数据来唯一地标识系统内的无线电。当无线电漫游时，网关为无线电提供与目的地区域相关的新的本地识别数据。给定区域中的每个无线电的本地识别数据由网关在存储器中映射，使得可用的本地标识数据可以被重新分配给漫游到网关区域中的无线电。然后，当无线电离开该区域时，给予无线电的本地识别数据被解除分配，使得其随后可以漫游到该区域的另一无线电装置可用。
