Problems solved by technology

[0008] As shown in the above example, in normal PoC services, even if it is a temporary problem, there is still a problem that only the users of the PoC-compatible terminal C located outside the circle cannot obtain the information notified in the same group

Embodiment Construction

[0075] FIG. 2 shows a first embodiment of the PoC server and the PoC service system using the PoC server of the present invention.

[0076] In this example, the PoC server 1 stores (accumulates) the media information when the PoC user is out of the circle, and reproduces and provides information required when the PoC user is in the circle again (group participation). In order to perform this control, the PoC server 1 has a group state table 101, a user state table 102, and a media log management table 141, and is provided with subscriber management in an external user database (HSS; Home Subscriber Server: Home Subscriber Server) 5. Form 501. The user dials the group number of the desired PoC service or PoC accumulation service, and joins the desired group. In the former PoC service, the usual radio transceiver function can be used between the participating users of the same group, and in the latter PoC accumulation service, it is also possible to listen to the accumulated da...

Abstract

The present invention provides a radio communication or a contents server for suitably storing and providing media contents from a group user in PoC services or the like. The contents server comprises a recording unit for recording, for each predetermined group, the media information from a plurality of users existing within a radio area and having participated in the group, a detecting unit for detecting the individual inside / outside-range states of the participant users for every predetermined time periods, and a deleting unit for deleting, when the detecting unit detects that the states of the participant users are all inside the range, the confirmed media information recorded in the recording unit on or before the detection.

Description

technical field [0001] The present invention relates to a content server and a content service system. The present invention particularly relates to a PoC server and a PoC service system that provide PoC (Push to talk over Cellular: wireless push-to-talk) service. The terminal acts as a radio transceiver (PTT; Push to Talk). Furthermore, the present invention also relates to a conference server and a conference system that provide conference services such as audio conferences and video conferences via an IP network. Background technique [0002] With the popularization of mobile phones in recent years, there is an increasing demand for new services such as high-speed data communication that transmits images or moving images in addition to the existing one-to-one audio call service. As one of such new services, the PoC service whose basic specifications are produced by 3GPP (the 3rd Generation Partnership Project: 3rd Generation Partnership Project) is also expected to sprea...
