An method for a computing device comprises: listing, in a first region, candidate items indicating events that are detectable through selected cameras; displaying, in a first sub-region of a second region, a first selected item indicating an event of a first candidate item from among the candidate items in response to a second user input for dragging the first candidate item and dropping same into the second region; and displaying, in a second sub-region, a second selected item indicating an event of a second candidate item from among the candidate items in response to a third user input for dragging the second candidate item and dropping same into the second-sub region. The displaying the second selected item in the second sub-region comprises a step of providing a graphic interface for grouping the first and second selected items in the second region.

Computing device for communicating with network system comprising plurality of cameras, and operating method therefor

Disclosed is a method of providing an early media service based on a session initiation protocol (SIP). More particularly, the present disclosure relates to a method of providing an early media service based on SIP, wherein an application server and a media server can provide early media of a multimedia form, such as images, moving images and the like, as well as audios, by using an early session or a regular session.

Method for providing early-media service based on session initiation protocol

Disclosed herein is a fast data call connection method capable of reducing a connection time and increasing the probability of connection success in a CDMA 2000 network. In the fast data call connection method of the present invention, the PDSN transmits a data call connection request message, including an authentication type and a challenge value, to the MS. The MS transmits a data call connection response message, including a response to the challenge value, to the PDSN. The PDSN performs authentication with reference to the data call connection response message, and transmits a data call connection complete message to the MS if authentication succeeds. Accordingly, the present invention is advantageous in that it can reduce connection time, can increase the probability of connection success, and can guarantee compatibility by checking the MS version before a data call connection process is executed.

Fast data-link connection method for saving connection time in CDMA 2000 network

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 when a call connection with a terminating terminal 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.
