    • Various embodiments of the invention relate to a low-cost network system that can reduce the network cost by connecting a base station controller (BSC) with a base transceiver station (BTS) by the use of matching units that match an E1/T1 line to an IP line. In one embodiment, the system comprises a BSC matching unit (BSCMU) and a BTS matching unit (BTSMU). The BSCMU, connected to the BSC through a first dedicated line, converts a first dedicated-line data signal, received from the BSC, into a first IP signal to be transmitted through an IP line and converts a received second IP signal into a second dedicated-line data signal to be transmitted to the BSC. The BTSMU, connected to the BTS through a second dedicated line, converts the first IP signal into the first dedicated-line data signal to be transmitted to the BTS and converts the second dedicated-line data signal, received from the BTS, into the second IP signal.
    • 本发明的各种实施例涉及一种低成本网络系统,其可以通过使用与E1 / T1线路匹配的匹配单元将基站控制器(BSC)与基站收发器(BTS)连接,从而降低网络成本 一条IP线路。 在一个实施例中,该系统包括BSC匹配单元(BSCMU)和BTS匹配单元(BTSMU)。 通过第一专用线连接到BSC的BSCMU将从BSC接收的第一专用线数据信号转换成要通过IP线路发送的第一IP信号,并将接收的第二IP信号转换成第二专用 线数据信号发送到BSC。 通过第二专用线连接到BTS的BTSMU将第一IP信号转换为第一专用线数据信号以发送到BTS,并将从BTS接收的第二专用线数据信号转换成第二专用线数据信号 IP信号。

    • In a method of offering an intelligent personalized learning service to learning participants, a pointer is assigned to each learning object and associated with each learning object belonging to a learning object database. A learning subject specific to each learning participant is selected from a learning subject database. Information on attempts at the learning objects associated with selected learning subject is recorded on learning history information of each learning participant. Performance completion information is recorded with respect to the learning objects attempted by the learning participant on the learning history information of each learning participant. A proficiency status of the learning participant is diagnosed for the selected learning subject corresponding to the learning participant based on the learning history information of each learning participant.
    • 在向学习参与者提供智能个性化学习服务的方法中,将指针分配给每个学习对象并与属于学习对象数据库的每个学习对象相关联。 从学习对象数据库中选择每个学习参与者特定的学习对象。 关于与选择的学习对象相关联的学习对象的尝试的信息记录在每个学习参与者的学习历史信息上。 关于学习参与者尝试的学习对象关于每个学习参与者的学习历史信息记录演奏完成信息。 基于每个学习参与者的学习历史信息,针对与学习参与者相对应的所选择的学习主体,诊断学习参与者的熟练状态。
