    • A method for transmitting Physical Downlink Control Channel (PDCCH) information, a method for determining PDCCH search space and devices thereof are disclosed in the present embodiments. The method for determining PDCCH search space includes the following step: Node B (NB) determines the different search spaces corresponding to different PDCCHs according to Carrier Indicator (CI) information. By applying the technical solution provided in the embodiments of the present invention, the CI information is introduced in the search space determining process, so that different search spaces can be allocated to the cross-carrier PDCCHs of one User Equipment (UE) and the NB and UE are able to exactly determine the search spaces of PDCCHs in each downlink carrier, therefore reducing the blocking probability during PDCCH scheduling process and improving the reliability of PDCCH transmission.
    • 在本实施例中公开了用于发送物理下行链路控制信道(PDCCH)信息的方法,用于确定PDCCH搜索空间的方法及其装置。 确定PDCCH搜索空间的方法包括以下步骤:节点B(NB)根据载波指示符(CI)信息确定与不同PDCCH相对应的不同搜索空间。 通过应用本发明实施例提供的技术方案,在搜索空间确定过程中引入了CI信息,从而可以将不同的搜索空间分配给一个用户设备(UE)和NB的跨载波PDCCH UE能够精确地确定每个下行链路载波中的PDCCH的搜索空间,因此降低了PDCCH调度过程中的阻塞概率,提高了PDCCH传输的可靠性。

    • The present invention discloses a name-to-address mapping system in a locator and identifier separation network. The system includes mapping nodes and access service nodes connected to each other through the network. The mapping node includes a transceiver module, a first storing module, a node determining module, a second storing module, and an address inquiring module. The present invention also discloses the corresponding method. In the present invention, the one-hop Distributed Hash Table (DHT) algorithm is used to generate a node routing table and a local mapping table whose performances are greatly improved when compared with the Content Addressable Network (CAN) algorithm, thus the phenomenon of the non-uniform distribution of mapping relations in mapping nodes caused by the operators assigning identities section-by-section can be avoided.
    • 本发明公开了一种定位器和标识符分离网络中的名称到地址映射系统。 该系统包括通过网络彼此连接的映射节点和接入服务节点。 映射节点包括收发模块,第一存储模块,节点确定模块,第二存储模块和地址查询模块。 本发明还公开了相应的方法。 在本发明中,与内容寻址网络(CAN)算法相比,使用一跳分布哈希表(DHT)算法生成节点路由表和局部映射表,其性能大大提高, 可以避免由运营商分配身份逐段引起的映射节点中映射关系的不均匀分布。

    • In a converged communication network, IP data packet services are provided by a core network to access terminals via radio access nodes (RAN). By positioning accounting report triggering closer to the usage, accuracy and comprehensive of accounting is achieved, which can also reduce overhead burdens on the core network. Additional responsibility is given to an access gateway (AGW) between an enhanced base station (eBS) of the RAN and the core network that can reduce the volume and increase the accuracy of accounting message traffic to an authentication, authorization and accounting (AAA) server of the core network. The AGW informs the eBS of accounting rules to be used in making air link records that are merged and formatted in accordance with an accounting protocol for sending to the AAA server, to address duration and volume based accounting needs, postpaid and prepaid accounting types, and user, service and flow based accounting categories.
    • 在融合通信网络中,IP数据分组业务由核心网提供,经由无线接入节点(RAN)接入终端。 通过定位会计报告更接近于使用,实现了会计的准确性和综合性,从而减轻了核心网络的负担。 对RAN的增强型基站(eBS)和核心网络之间的接入网关(AGW)进行额外的责任,能够减少认证,授权和计费(AAA)服务器的计费消息流量的容量并提高其准确性 的核心网络。 AGW通知会计规则的eBS,用于根据用于发送到AAA服务器的会计协议来合并和格式化空中链路记录,解决持续时间和基于卷的会计需求,后付费和预付费会计类型,以及 用户,服务和流程的会计类别。
