| 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 |
| 20100121963 | Method and Device for Obtaining Media Description Information of IPTV Services - A method and device for obtaining media description information of Internet Protocol Television (IPTV) services are provided. The method includes: receiving, by a network device, a Session Initiation Protocol (SIP) request for obtaining media description information, where the SIP request is sent by a User Equipment (UE) through a core IP Multimedia Subsystem (IMS) and carries a content identifier; sending, by the network device, a SIP response that carries the media description information corresponding to the content identifier to the UE through the core IMS. According to the present disclosure, a SIP message is used to obtain media description information, so that a session of the Content on Demand (CoD) service is set up. | 05-13-2010 |
| 20110023071 | Method, System, and Apparatus for Creating Content-on-Demand Service - A method, a system, and an apparatus for creating a Content-on-Demand (CoD) service are disclosed herein. The method includes receiving a Session Initiation Protocol (SIP) service request sent by a User Equipment (UE); converting the SIP service request into a Real-Time Streaming Protocol (RTSP) service request, and sending the RTSP service request to a server; receiving an RTSP service response sent by the server; and converting the RTSP service response into a SIP service response, and sending the SIP service response to the UE to create the CoD service between the UE and the server. | 01-27-2011 |
| 20110060900 | METHOD, SYSTEM, CORRESPONDING DEVICE, AND COMMUNICATION TERMINAL FOR PROVIDING MBMS SERVICE - A method, a system, a security device, a service control device, and a communication terminal for providing a Multimedia Broadcast/Multicast Service (MBMS) service are provided. The method includes the following steps: A service control module in an IP Multimedia Subsystem (IMS) system carries out service authorization according to a service authorization request, and obtains an authorization-passed result. The service control module sends the authorization-passed result to a security module. The security module obtains the authorization-passed result and then sends a service decryption code of the MBMS service to UEs. In the present invention, a controlling capacity of an IMS and a bearer capacity of an MBMS are multiplexed based on an IMS system and an MBMS system to achieve IPTV services, so as to achieve the uniform authorization and uniform network management. The binding of the IPTV service with other services based on the IMS can be achieved by using the IMS, and personalized services can be provided to UEs. | 03-10-2011 |
