    摘要: The invention relates to a method for managing the mobility of a mobile node that moves to a different network, but keeps the same IP address. It is proposed to perform route optimization by a Proxy MIP agent on behalf of the MN, thereby shortening the data-path while allowing network-based mobility. At session setup with a correspondent node, the PCC system in the home network derides whether route optimization is to be performed for the communication session. The PMIPa requests relevant information for the route optimization, including the decision for route optimization and the addresses of MN and CN, from the PCC system in the home network, when the MN attaches to the new network area. Accordingly, route optimization is performed by using the Return Routability Procedure according to MIPv6, thereby applying the MN's IP address as Home Address, and the PMIPa's address as Care-of Address of the MN.

    摘要: The invention relates to a method for configuring a context for a connection delivering a packet data service to a mobile terminal via a target wireless access network. The mobile terminal is initially connected to an originating wireless access network and the packet data service may be provided to the mobile terminal via the originating wireless network. Moreover, the invention provides an authentication server, a packet data gateway and a packet data service support node which participate in the context configuration method. To provide a method that allows establishing connection for packet service delivery to a mobile terminal from a wireless access network, as for example a UMTS, as fast as possible the invention suggests to preconfigure service provision of the packet data service via the target wireless access network by establishing a context prior to the mobile terminal connecting to the target wireless access network.

    摘要: The invention relates to a method for controlling 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 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 selecting a subset of the mobile terminals of the mobile communication system and which receive the multicast or broadcast service for providing feedback to a feedback control entity. In one embodiment of the invention the terminals may decide whether to provide feedback based on a probabilistic experiment performed based on parameters determined and provided by the feedback control entity.

    摘要: The invention relates to a method for efficiently providing a bidirectional multicast service (e.g. IMS) to a user equipment (105), located in a radio cell, controlled by a control entity (104). For the downlink data of the bidirectional service a downlink multicast service (e.g. MBMS) is utilized. In case the control entity (e.g. RNC) decides for a point-to-point radio link to the UE, the bidirectional service is notified and system resources, established for the bidirectional service are utilized for providing the bidirectional service downlink data. This includes radio resources in the radio access network and may include connections in the core network. Optionally, the downlink multicast service may be de-activated for the specific mobile terminal, but the system resources already established may be maintained. 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.

    摘要: 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.

    摘要: 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.
