    • A paging method may reduce signaling overhead of system paging and save system paging resources. The method includes: receiving, by an eNodeB, a paging message, where the paging message carries a tracking area identity; paging a user equipment if the tracking area identity in the paging message is the tracking area identity of the eNodeB; and instructing a relay to page. A location update method is also disclosed, which reduces signaling load produced by location update. The method includes: generating, by a relay, a system message, where the system message includes a tracking area identity of the relay; and broadcasting the system message, and triggering a user equipment in a cell of the relay to initiate a location update request. The embodiments of the present invention disclose an eNodeB, a relay, a communication system.
    • 寻呼方法可以减少系统寻呼的信令开销并节省系统寻呼资源。 该方法包括:由eNodeB接收寻呼消息,其中寻呼消息携带跟踪区域标识; 如果寻呼消息中的跟踪区域标识是eNodeB的跟踪区域标识,则寻呼用户设备; 并指示中继页面。 还公开了一种位置更新方法,其减少了由位置更新产生的信令负载。 该方法包括:由中继产生系统消息,其中系统消息包括继电器的跟踪区标识; 并且广播系统消息,并触发中继的小区中的用户设备发起位置更新请求。 本发明的实施例公开了一种eNodeB,中继,通信系统。

    • A method and apparatus for measuring target gas concentrations in an atmosphere. The method and apparatus emit in the atmosphere a laser beam tuned to a molecular absorption line of a target gas, receive a reflected signal affected by gas absorption of the target gas in the atmosphere, divide and direct the received signal into a first optical path and a second optical path including in one of the paths a correlation gas cell filled with a predetermined concentration of the target gas, detect transmitted signals through the first optical path and the second optical path, and calculate a target gas concentration by comparing a first signal transmitted through the first optical path to a second signal transmitted through the second optical path. The apparatus includes a laser source tunable to a specific molecular absorption line of a target gas and configured to emit in the atmosphere a laser beam having a spectral bandwidth greater than a full width of the molecular absorption line of the target gas, a receiver configured to receive a reflected signal affected by gas absorption of the target gas in the atmosphere, and at least one detector configured to detect transmitted signals through the first optical path and the second optical path.
