    摘要： The present invention relates to a transition metal complex useful as a transition metal catalyst in the preparation of an ethylene homopolymer or a copolymer of ethylene and an α-olefin, a catalyst composition comprising the same and a process of preparing an ethylene homopolymer or a copolymer of ethylene and an α-olefin using the same. More particularly, it relates to a transition metal complex having a cyclopentadiene derivative and at least one phenyl oxide ligand substituted at the 2-position of phenyl with, for example, a silyl group having a C1-C30 hydrocarbon group or a C1-C20 hydrocarbon group, around a group IV transition metal, with no crosslinkage between the ligands, a catalyst composition comprising the transition metal complex and a cocatalyst selected from the group consisting of an aluminoxane and a boron compound, and a process for preparing an ethylene homopolymer or a copolymer of ethylene and an α-olefin using the same.

    摘要： A method and system are provided for servicing a full duplex call in Push-To-Talk over cellular (PoC) in a communication system including at least two or more calling/called terminals for receiving a Push-To-Talk (PTT) service and a mobile network for providing the PTT service to the calling/called terminals. The calling terminal generates a full-duplex mode request message and transmits the full-duplex mode request message to the mobile network. The mobile network transmits the full-duplex mode request message to a PoC server that provides a PoC service to the calling terminal. Upon receiving the full-duplex mode request message, a PoC server of the calling terminal sets the calling terminal to a full duplex mode, and transmits the full-duplex mode request message to a PoC server of the called terminal. The PoC server of the called terminal transmits the full-duplex mode request message to the called terminal, and performs a call between the calling terminal and the called terminal in the full duplex mode if the called terminal responds to the full-duplex mode request message.

    摘要翻译： 提供了一种方法和系统，用于在包括用于接收一键通（PTT）服务的至少两个或更多个呼叫/被叫终端的通信系统中通过蜂窝（Push-To-Talk over cellular）（PoC）进行全双工呼叫的服务，以及 用于向呼叫/被叫终端提供PTT服务的移动网络。 主叫终端生成全双工模式请求消息，并将全双工模式请求消息发送到移动网络。 移动网络将全双工模式请求消息发送到向呼叫终端提供PoC服务的PoC服务器。 在接收到全双工模式请求消息时，主叫终端的PoC服务器将主叫终端设置为全双工模式，并将全双工模式请求消息发送到被叫终端的PoC服务器。 被叫终端的PoC服务器向被叫终端发送全双工模式请求消息，如果被叫终端响应全双工模式请求消息，则以全双工模式在主叫终端和被叫终端之间进行呼叫 。
