    • A method for supporting handoff and preventing data loss in mobile communications networks is provided. The method for a mobile node establishing a mobile Internet protocol (MIP) with at least one or more wireless packet service systems, each of which has a serving GPRS support node (SGSN) and a gateway GPRS support node (GGSN), includes: a first SGSN connected to the mobile node transmitting predetermined first connection information on the mobile node to at least one or more second SGSNs adjacent to the first SGSN; the second SGSN receiving the first connection information storing the first connection information as a database item, and transmitting 1 first connection acknowledgement message to the first SGSN; if reception of the connection acknowledgement message is successful, the first GGSN connected to the first SGSN transmitting predetermined second connection information on the mobile node to at least one or more second GGSNs connected to the second SGSN; and the second GGSN receiving the second connection information and then transmitting a second connection acknowledgement message to the second GGSN. By transmitting information on a mobile node required for handoff to adjacent foreign agents (FAs) in advance, when handoff is performed, reliable handoff can be performed quickly without resetting and releasing a PPP, such that IP mobility services can be provided.
    • 提供了一种支持切换和防止移动通信网络中的数据丢失的方法。 移动节点建立具有至少一个或多个无线分组业务系统的移动节点(MIP)的方法,每个无线分组业务系统具有服务GPRS支持节点(SGSN)和网关GPRS支持节点(GGSN),包括: 连接到所述移动节点的第一SGSN将所述移动节点上的预定的第一连接信息发送到与所述第一SGSN相邻的至少一个或多个第二SGSN; 第二SGSN接收存储第一连接信息的第一连接信息作为数据库项,并向第一SGSN发送第一连接确认消息; 如果连接确认消息的接收成功,则连接到第一SGSN的第一GGSN将移动节点上的预定第二连接信息发送到连接到第二SGSN的至少一个或多个第二GGSN; 并且第二GGSN接收第二连接信息,然后向第二GGSN发送第二连接确认消息。 通过事先向相邻的外部代理(FA)发送切换所需的移动节点上的信息,在执行切换时,可以快速地执行可靠的切换,而无需重新设置和释放PPP,从而可以提供IP移动业务。

    • Disclosed herein is an apparatus for controlling the capacity of an air conditioner and a control method using the same. The capacity control apparatus is configured in such a fashion that a 3-way or 4-way direction-switching member and a low-pressure equalizing solenoid valve are provided at a refrigerant path of the air conditioner having a pair of first and second compressors, so that the compression capacity of the air conditioner is adjusted into three stages of 100%, 60%, and 40% using the first and second compressors, enabling easy variable-capacity operation. This has the effect of considerably reducing energy consumption and of preventing wear of the first and second compressors via a rapid compensation of a pressure unbalance between both the compressors. As a result, under any operating condition, it is possible to prevent a liquid backflow phenomenon from occurring when starting operation of the compressors, resulting in an improvement in the reliability and operation efficiency of the compressors.
    • 这里公开了一种用于控制空调的容量的装置和使用其的控制方法。 容量控制装置被构造成在具有一对第一和第二压缩机的空调器的制冷剂路径处设置三通或四通方向切换构件和低压均衡电磁阀, 因此使用第一压缩机和第二压缩机将空调机的压缩容量调整为100%,60%,40%的三级,从而容易进行变容量运转。 这具有通过快速补偿两个压缩机之间的压力不平衡而显着降低能量消耗并防止第一和第二压缩机的磨损的效果。 结果,在任何操作条件下,可以防止压缩机开始运转时发生液体回流现象,从而提高压缩机的可靠性和运行效率。
