    • A method and apparatus for allocating time slots in a baseband EPCN system is provided. The method includes: obtaining a period type of a current period; and determining a proportion between uplink time slots and downlink time slots for the current period according to the period type. According to present invention, different proportions between uplink time slots and downlink time slots may be respectively applied to different periods such as a registration period and a communication period in the baseband EPCN system. Thus, the register time of a new CNU in the registration period is shortened and the requirement for high downlink bandwidth for normal communications in the communication period is guaranteed at the same time.
    • 提供了一种用于在基带EPCN系统中分配时隙的方法和装置。 该方法包括:获取当前周期的周期类型; 以及根据周期类型确定当前周期的上行链路时隙和下行链路时隙之间的比例。 根据本发明,上行链路时隙和下行链路时隙之间的不同比例可以分别应用于基带EPCN系统中的注册周期和通信周期等不同的周期。 因此,注册期间新CNU的注册时间缩短,同时保证通信期间正常通信的高下行链路带宽需求。

    • The present invention sets forth a method for content responding, a method for content requesting, a content responder and a content requester. A content responder receives a first request from a content requester via a network. Then, the content responder generates a first content based on the first request. Then the content responder receives a second request from the content requester via the network. Then, the content responder generates a second content based on the second request. Next, the content responder compares the second content with the first content. After that, the content responder transmits a second response with regard to the second request to the content requester via the network. The second response is generated based on the result of comparison. According to the invention, if there is a very small difference between the first content and the second content, network bandwidth can be saved, the transmitting time of content will be reduced, and thus the waiting time of the user to view content will be reduced. The present invention is particular beneficial to the existing industries (for example, the banking industry) that adopt narrow band network widely.
    • 本发明提出了一种用于内容响应的方法,一种内容请求方法,一种内容应答器和一种内容请求者。 内容响应者经由网络从内容请求者接收第一请求。 然后,内容响应者基于第一请求生成第一内容。 然后内容响应者经由网络从内容请求者接收第二请求。 然后,内容响应者基于第二请求生成第二内容。 接下来,内容响应者将第二内容与第一内容进行比较。 之后,内容响应者经由网络向第二请求发送关于第二请求的第二响应。 第二个响应是根据比较结果生成的。 根据本发明,如果第一内容和第二内容之间存在非常小的差异,则可以节省网络带宽,内容的发送时间将被减少,因此用户观看内容的等待时间将被减少 。 本发明对于广泛采用窄带网络的现有行业(例如银行业)特别有利。
