    • A microdischarge photodetector has a photocathode, an insulator and an anode. A cavity of limited size is disposed in the insulator and filled with gas. A voltage applied between the photocathode and the anode produces a plasma. Light incident on the photocathode having photon energies larger than about the work function produces photoelectrons are ejected from the photocathode and accelerated by the plasma electric field. The incident light is detected by detecting an increase in the plasma current or light emission from the plasma. The cavity may be flat or tapered and is designed to optimize detector performance.

    • A method for disclosing, by a Converged Personal Network Service (CPNS) server, Personal Network (PN) information in a CPNS environment is provided. The method includes receiving a PN registration request message including information indicating an information openness level of a Personal Network Entity (PNE), which has been transmitted from the PNE, from a Personal Network GateWay (PN GW) for PN registration of the PNE; checking and storing the information indicating the information openness level of the PNE from the PN registration request message; receiving a service search request message for requesting information regarding a CPNS service provided by the PNE from a predetermined PN GW connected to a predetermined PNE; and checking the information indicating the information openness level of the PNE and providing the information regarding the CPNS service provided by the PNE to the predetermined PNE via the predetermined PN GW.

    • Disclosed is a method for enabling a terminating-side Push-To-Talk (PTT) over Cellular (PoC) client to open a PoC session by using a pre-established session, and to maintain the pre-established session when the terminating-side PoC client terminates the open PoC session, and a PoC system and a PoC User Equipment (UE) for implementing the same. To this end, a REFER BYE message is used to terminate the PoC session while keeping the pre-established session maintained. The REFER BYE message must include information, such as pre-established session parameter information, a session IDentifier (ID), etc. Also, the REFER BYE message is transmitted from the PoC client to the PoC server, and the PoC server receives the REFER BYE message, checks the contents of a header in the received message, and terminates the PoC session while keeping the pre-established session maintained when a specified condition is satisfied.
    • 公开了一种使终端侧按通话(PTT)通过蜂窝(PoC)客户机通过使用预先建立的会话来打开PoC会话的方法,并且当终端侧保持预先建立的会话时 PoC客户端终止开放的PoC会话,PoC系统和PoC用户设备(UE)实现该PoC会话。 为此,使用REFER BYE消息来终止PoC会话,同时保持预先建立的会话。 REFER BYE消息必须包括诸如预先建立的会话参数信息,会话标识符(ID)等的信息。此外,REFER BYE消息从PoC客户端发送到PoC服务器,PoC服务器接收REFER BYE消息,在接收到的消息中检查报头的内容,并在满足指定条件的同时保持预先建立的会话,终止PoC会话。
