Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The present invention provides immunogenic oligosaccharide compositions and methods of making and using them. In particular, the compositions comprise native O-linked and S-linked oligosaccharides coupled to a protein carrier via a linker, wherein the resultant conjugate elicits a protectively immunogenic response, particularly in vaccines against pathogenic Candida species and more particularly against Candida albicans. Preferably the pathogenic Candida species are those that possess cell wall oligosaccharide compositions similar to the ?-mannan component of Candida albicans cell walls.

Abstract: A steering component is included in an ion implantation system to direct or “steer” an ion beam to a scan vertex of a scanning component downstream of the steering component. In this manner, the scan vertex of the scanning component coincides with the focal point of a parallelizing component downstream of the scanning component. This allows the beam to emerge from the parallelizing component at an expected angle so that ions can be implanted in a desired manner into a workpiece located downstream of the parallelizing component.

Abstract: The present invention concerns a method of tuning a plurality of electrostatic quadrupoles used for focusing an ion beam implanter. The steps of the method include: classifying the plurality of electrostatic quadrupoles into one of a predetermined number of groups, and for each of the predetermined number of groups, tuning the quadrupoles in the group by iteratively substituting values for a voltage ton be applied to each of the quadrupoles in the group using a multi-variable heuristic algorithm and concurrently measuring final beam current measured downstream of the ion accelerator to determine a set of applied voltage values that maximize the final beam current among those applied voltage values tested and utilizing the set of applied voltage values to tune the quadrupoles in the group. If the resulting ion beam is suitable, utilizing the determined applied voltages to tune the quadrupoles.
