20080212583 | Adaptive and Scalable Qos Architecture for Single-Bearer Multicast/Broadcast Services - The present invention relates to a method for filtering a multiplexed packet stream in a network entity of the core network or the radio access network of a mobile communication system. The multiplexed packet stream provides a multicast or broadcast service and is delivered from a service center via the network entity to a mobile terminal. Further, the network entity comprises a service manager providing a quality-of-service management function. The invention further relates to a network entity provided with filtering capabilities, as well as to a communication system comprising the network entity. To provide an adaptive multimedia broadcast/multicast service QoS architecture that is scalable to a great number of users the invention suggests providing the service in form of a multiplexed packet stream via a single bearer service an equipping nodes within the distribution tree of the service filter capability allowing to filter the multiplexed stream based on the downlink quality-of-service constraints obtained from a service manager. | 09-04-2008 |
20080293428 | Adaptive and Scalable Qos Architecture for Multi-Bearer Multicast/Broadcast Services - The invention relates to a method for filtering and a network entity of the core network or the radio access network of a mobile communication system filtering streams belonging to a single user service. The packet streams, each being transported by a bearer service, provide a multicast or broadcast service and is delivered from a service center via the network entity to a mobile terminal. The network entity comprises a service manager providing a quality-of-service management function. The invention further relates to a communication system comprising the network entity. To provide an adaptive multimedia broadcast/multicast service QoS architecture that is scalable to a great number of users, the invention suggests providing the service in form of a packet streams, each being provided via a single bearer service, and equipping nodes within the distribution tree of the service filter capability allowing to (de)register bearer services providing the service based on the downlink quality-of-service constraints obtained from a service manager. | 11-27-2008 |
20090213775 | DETERMINISTIC FEEDBACK CONTROL FOR MULTICAST OR BROADCAST SERVICES - The invention relates to a method for controlling the transmission of feedback of mobile terminals receiving via an air interface of a mobile communication system a multicast or broadcast service transmitted or forwarded by a feedback control entity and to a mobile terminal, the feedback control entity using this method. Further, a communication system comprising a feedback control entity and a mobile terminal receiving a multicast or broadcast service is provided. To enable configurable and adaptive feedback for multicast or broadcast services provided via an air interface maintaining the end-to-end session concept the invention suggests that a feedback control entity deterministically selects a subset of the mobile terminals of the mobile communication system and which receive the multicast or broadcast service for providing feedback to the feedback control entity. In one embodiment of the invention the terminals are instructed to start or stop feedback provision by the feedback control entity by means of signaling. | 08-27-2009 |

20080298294 | Inter-Domain Group-Communications - The invention relates to group communication services, i.e. communication services involving two or more users (or service participants). The invention provides a method for distributing multicast data of a multicast service to different domains and a method for distributing multicast data to service participants in a domain. Further, the invention relates to a control node and system implementing the respective methods. To improve resource utilization when providing a multicast service, including inter alia PoC services, to service participants the invention provides mechanisms to avoid unnecessary multiplication of multicast data in the distribution tree for multicast services with service participants of different domains. For this purpose the controlling node that is initiating the multicast service upon request determined to which domains the multicast data is to be provided and only forwards the multicast data on a per-domain basis. Another aspect of the invention is the avoidance of unnecessary duplications of multicast data within individual domains. | 12-04-2008 |
20090005056 | Efficient Provision of a Multicast Service by Switching Between Multicast Services in a Mobile Communication System - The invention relates to a method for efficiently providing a bidirectional multicast service (e.g. IMS) to a user equipment ( | 01-01-2009 |
20090010195 | Efficient Multicast Service Data Provision in a Mobile Communication System - The invention relates to a method for efficiently setting up a bidirectional multicast service in a mobile communication system. The bidirectional service is provided to a user equipment located in a radio cell controlled by a control entity. For the downlink data of the bidirectional service a downlink multicast service framework is utilized. In case the control entity decides for a point-to-point radio link to the UE, the system resources of the downlink framework are configured so as to re-use the configured system resources of the bidirectional service. This includes radio resources in the radio access network and may include tunnels in the core network. The invention further relates to a network entity in the CN or in the RAN for configuring system resources and for forwarding the multicast service data to the UE. The invention also relates to a mobile terminal for receiving the bidirectional multicast service. | 01-08-2009 |
20090172170 | ESTABLISHMENT OF MEDIA SESSIONS WITH MEDIA ADAPTATION - The present invention relates to a method and terminal for reporting media format adaptation resources to convert a media format of a media stream of a media session to be established between terminals through a packet switched communications network towards a requesting terminal. The invention further relates to a method and NSIS router for reporting media format adaptation resources for converting a media format of a media stream of a media session to be established between terminals. To allow terminals to establish a media session utilizing media adaptation, the invention provides a NSIS (Next Step In Signaling) based signaling framework facilitating the detection and reservation of media adaptation resources on (and off) a media data path on which media data are transported utilizing a media transport protocol among terminals participating in the session. | 07-02-2009 |
