    • Disclosed is a system and method for providing a mobile communication terminal with network-based location measurement according to locations by using a G-pCell database. The system includes an NPS for storing a neighboring base station database and a G-pCell database; and an SPC for detecting the location of a base station by parsing a base station signal received from the mobile communication terminal when a location measurement request signal is received from the mobile communication terminal, and determining a location of the mobile communication terminal by using a G-pCell pattern matching algorithm when the number of base stations neighboring the mobile communication terminal, detected by parsing the base station signal, is less than the stored number of neighboring base stations corresponding to the location of the base station, discovered using the neighboring base station database. Considering that the accuracy of location measurement may be lowered when the G-pCell pattern matching algorithm is applied to the upper stories of a high-rise building in an area where high-rise buildings stand closely together, such as a downtown area, the system and method selectively uses the G-pCell pattern matching algorithm or a location measurement algorithm based on triangulation to position a mobile communication terminal according to a rough location of the mobile communication terminal, thereby further improving the accuracy of location measurement.

    • The present invention relates to a method of providing an early media service based on a session initiation protocol (SIP), wherein early media of a multimedia form can be provided under SIP-based B2BUA mode operation.
      According to the present invention, in a case where early media are provided to an originating terminal (10) when a call connection with a terminating terminal (50) is established at the request of the originating terminal, the early media is provided in the form of multimedia data, such as text, image, moving image, flash animation and the like, as well as audio data, and thus users desires are fulfilled and users satisfactions are maximized. In addition, with individual operation management of the terminating terminal and the originating terminal according to B2BUA mode operation based on the session initiation protocol and an early session initiation with the originating terminal, an early media service can be normally provided to the originating terminal even when the terminating terminal is in an abnormal operation state.
    • 本发明涉及一种基于会话发起协议(SIP)提供早期媒体业务的方法,其中可以在基于SIP的B2BUA模式操作下提供多媒体形式的早期媒体。 根据本发明,在与起始终端的请求建立与终接终端(50)的呼叫连接的情况下,向始发终端(10)提供早期媒体的情况下,提供早期媒体的形式 的多媒体数据,例如文本,图像,运动图像,Flash动画等,以及音频数据,从而满足用户期望并使用户满意度最大化。 另外,通过基于会话发起协议的B2BUA模式操作对终端终端和始发终端进行个体操作管理,以及与始发终端的早期会话启动,即使在始发终端也可以提供早期媒体业务 终端处于异常运行状态。
