20080301308 | SYSTEM, METHOD AND APPARATUS FOR ESTABLISHING INTERACTIVE MEDIA SESSION BASED ON IP MULTIMEDIA SUBSYSTEM - A method and system for establishing an interactive media session based on an IP Multimedia Subsystem, including: a terminal adapted to initiate an interactive media session request and receive a media session response; a serving-CSCF adapted to trigger the request to the application server according to a triggering rule and route the message; a proxy-CSCF adapted to forward the request and the response between the terminal and the serving-CSCF; an application server adapted to process the service request; a media control entity adapted to control resource allocation of the media carrier entity; and a media carrier entity adapted to allocate address ports for RTSP connection and RTP connection with the terminal. The present invention can be applied to a NGN network where the carrier and control are separated to improve the media delivery efficiency. | 12-04-2008 |
20080301747 | METHOD AND SYSTEM FOR MEDIA RESOURCE SCHEDULING - An IMS-based media resource scheduling method includes: initiating a media resource request by an Application Server (AS) to a media routing functional entity; determining a media server by the media routing functional entity; and routing the media resource request to the determined media server. The disclosure also provides an IMS-based media resource scheduling system, a Media Resource Locating Function (MRLF), a Media Resource Broker Function (MRBF), and a Media Resource Function Controller (MRFC). According to the disclosure, the media resource scheduling process is implemented and the user's QoS requirement is satisfied by selecting a suitable one from at least one media server for providing stream media service to the UE. | 12-04-2008 |
20080307108 | STREAMING MEDIA NETWORK SYSTEM, STREAMING MEDIA SERVICE REALIZATION METHOD AND STREAMING MEDIA SERVICE ENABLER - The present invention provides an IMS-based streaming media network system comprising: a streaming media service enabler configured to provide streaming media service description information to a user terminal; an application server configured to send a media resource request after the user terminal selects a streaming media service based on the service description information provided by the streaming media service enabler and after receiving a streaming media service request sent from the user terminal, and to provide the user terminal with information on a media resource delivery processing function entity storing streaming media contents after acquiring the information on the media resource delivery processing function entity; and, a media server configured to provide the application server with the information on the media resource delivery processing function entity storing the streaming media contents, based on the media resource request sent from the application server. The present invention addresses the problem of realizing streaming media services on the basis of IMS-based network architecture. | 12-11-2008 |
20080310637 | Method, System And Rights Issuer For Generating And Acquiring Rights Objects - A method and system for generating and acquiring rights objects according to the embodiments. In the present disclosure, the generation and acquisition of rights objects is implemented as a service function or a service support function; a rights issuer is deployed as an application server or as a service support entity for an application server. Therefore, the present disclosure makes full use of all existing entities and operating mechanisms in an IMS network and provides an optimized method and system for generating and acquiring rights objects. Furthermore, the rights issuer may obtain user requests or online state information of users via the IMS. In addition, the present disclosure provides a rights issuer. | 12-18-2008 |
20090245256 | METHOD AND SYSTEM FOR PROVIDING MULTICAST SERVICES - The present disclosure discloses a method for providing multicast services, which includes receiving a multicast service request sent by a UE through an IMS network, obtaining the media transmission parameters of the multicast media streams, sending a response to the UE through the IMS network with the media transmission parameters carried in the response, and sending the multicast media streams corresponding to the media transmission parameters to the UE. Further, a system providing multicast services and a multicast service support system is disclosed. | 10-01-2009 |
20090260032 | METHOD AND SYSTEM FOR DISCOVERING STREAMING SERVICES, AND SERVICE DISCOVERY APPARATUS - The present disclosure provides a method and system for discovering streaming services, and a service discovery apparatus. The method includes steps as follows: The IMS network side generates streaming service information, and sends the information to a UE according to the information of the UE accessing the IMS network. The method, system and service discovery apparatus are based on IMS technologies. The service discovery unit may send the streaming service information to the UE automatically according to the information of the UE accessing the IMS network, without requiring requests from the UE or the address of the EPG generating unit. | 10-15-2009 |
20090260033 | APPARATUS AND METHOD FOR IMPLEMENTING IPTV SERVICE - Systems, apparatuses, and methods for implementing IPTV service are disclosed according to the present invention. In particular, a user equipment initiates an IPTV service request to an IPTV application subsystem in an IMS session. The IPTV application subsystem acquires content description from a service selection function entity according to the IPTV service request, and enables a multimedia delivery subsystem to provide content to the user equipment based on the acquired content description. According to the present invention, a content description function entity is provided in the system. The content description function entity is able to provide content description which may be utilized in the IMS session procedure for the purpose of implementing IPTV service. | 10-15-2009 |
