Abstract: An approach is provided for crowd sourcing and grouping points-of-interest based on cell broadcast message information. Reception of a message from a mobile terminal is caused, at least in part. The message specifies point-of-interest information and an associated area name corresponding to one of a plurality of cells of a communication network. The message is parsed to determine the point-of-interest information and the associated area name. A connectivity graph specifying relationships among the cells is selectively updated with the point-of-interest information.

Abstract: The present invention discloses a method for multicast content pushing between a server entity (UA-I) and at least one client entity (UA-II) as well as a corresponding system and client and server entities. The method comprises the steps of inviting, by the server entity, at least one client entity to join a multicast content streaming session, answering, by the at least one client entity to the server entity, whether the client entity joins the invited multicast content streaming session, releasing, at the server entity and to the server entity, a request for multicast content streaming, responding, by the server entity, to the released request by sending a response to the request to the at least one client entity that joined the multicast content streaming session.

Abstract translation: 本发明公开了一种在服务器实体（UA-I）和至少一个客户端实体（UA-II）以及对应的系统和客户端和服务器实体之间推送多播内容的方法。 所述方法包括以下步骤：由所述服务器实体邀请至少一个客户端实体加入多播内容流传输会话，由所述至少一个客户端实体向所述服务器实体应答所述客户端实体是否加入所请求的多播内容流 会话，在服务器实体和服务器实体处释放对多播内容流的请求，由服务器实体响应于所发布的请求，通过向加入多播的至少一个客户端实体发送对请求的响应 内容流媒体会话。

Abstract: An improved system and method for permitting a transmitting electronic device to indicate explicitly which streams in a multimedia stream being transmitted should not be synchronized or should include a specified amount of synchronization jitter. The present invention aids the receiving device in understanding the stream characteristics. The present invention also allows the receiving device to make an informed decision as to whether an synchronization jitter value should be used when synchronizing two or more streams. For certain applications such as uni-directional video sharing or video PoC, the sending device of the stream can indicate that the receiving device doesn't perform any or limited synchronization for better media quality.

Abstract: A method for exchanging content between a server entity (UA-I) and a client entity (UA-II). The method includes establishing a session between the server entity and the client entity based on a session control layer protocol, initiating a content exchange session between the server entity and the client entity based on an application layer session protocol. Furthermore, the method includes transmitting intra-session control data based on a transport mechanism of the session control layer protocol, wherein the intra-session control data controls the content exchange session.
