    • The present document discloses a method and system for realizing virtual machine mobility, comprising: in a process of establishing communication with a second virtual machine, a first virtual machine subscribing to a media access control (MAC) address change notification of the second virtual machine from an address resolution server (ARS) through a first virtual switch in a physical server where the first virtual machine is located; after the second virtual machine migrates, a second virtual switch in a physical server, to which the second virtual machine migrates, registering a corresponding relationship between an IP address of the second virtual machine and a MAC address of the second virtual switch itself to the ARS; and the ARS updating the MAC address corresponding to the IP address of the second virtual machine, and notifying the first virtual machine of the updated MAC address according to the subscription of the first virtual machine.
    • 本文件公开了一种用于实现虚拟机移动性的方法和系统,包括:在与第二虚拟机建立通信的过程中,第一虚拟机订阅第二虚拟机的媒体访问控制(MAC)地址改变通知, 通过第一虚拟机所在物理服务器中的第一虚拟交换机的地址解析服务器(ARS); 在第二虚拟机迁移之后,第二虚拟机迁移到的物理服务器中的第二虚拟交换机将第二虚拟机的IP地址与第二虚拟交换机本身的MAC地址之间的对应关系注册到ARS ; 并且所述ARS更新与所述第二虚拟机的IP地址相对应的MAC地址,并且根据所述第一虚拟机的预约通知所述第一虚拟机所述更新的MAC地址。

    • A method or system for managing demand-based multicast services in a wireless communications system (WCS) capable of both unicast and multicast signaling may include providing content requested by a mobile entity in an area of the WCS via a unicast session, determining that a concurrent demand level for the content exceeds a defined threshold for the area of the WCS, and initiating a multicast session for the content in the area of the WCS, in response to determining the concurrent demand level has exceeded the threshold. The method or system may include more detailed operations or aspects for measuring the concurrent demand level, transitioning signaling between unicast and multicast modes, communicating between network components, or related functions.

    • In a first configuration, an apparatus determines subframes, in a radio frame, used by one or more neighboring BSs for providing services, and sends information to a UE indicating the determined subframes. In a second configuration, an apparatus determines subframes, in a radio frame, used by one or more neighboring BSs for providing services, transmits with a first power in remaining subframes other than the determined subframes in the radio frame, determines a second power based on the first power such that a difference between the second power and the first power is less than a threshold, and transmits with the second power in a subset of symbols in the determined subframes. In a third configuration, an apparatus receives information from a BS indicating subframes, in a radio frame, used by one or more neighboring BSs for providing services, and adjusts an AGC gain based on the indicated subframes.
    • 在第一配置中,设备确定由无线帧中的一个或多个相邻BS用于提供服务的子帧,并向UE指示所确定的子帧的信息。 在第二配置中,设备确定由无线帧中的一个或多个相邻BS用于提供服务的子帧,在无线电帧中确定的子帧以外的剩余子帧中以第一功率进行发送,基于 所述第一功率使得所述第二功率和所述第一功率之间的差小于阈值,并且以所确定的子帧中的符号子集中的所述第二功率进行发送。 在第三种配置中,装置从BS指示指示在一个或多个相邻BS中用于提供业务的无线帧中的子帧的信息,并且基于所指示的子帧来调整AGC增益。
