The presentity and the watcher are respectively connected to a connection server through a network. The presentity belongs to at least one group, and the watcher also belongs to at least one group. The connection server can detect the latest status of the groups to which the presentity belongs.

The invention relates to method for providing a multicast service from or via an application server to a mobile terminal within a mobile communication system, wherein the mobile communication system provides a downlink multicast or broadcast service (DMBS) that can be utilized for transmitting the downlink multicast data to the mobile terminal. Further, the invention relates to a mobile terminal and network entities that participate in this method. To enable an efficient provision of a bidirectional multicast service to users, wherein a DMBS may be used for providing downlink multicast data to the users, the invention proposes that the mobile terminal requests an application server to route downlink multicast data through the resources established for the multicast service instead of the resources for the DMBS, upon receiving a notification that a point-to-point connection is to be used for the downlink multicast data transfer. Thereby, the establishment of additional RAN resources for DMBS can be prevented.
The invention relates to a method for managing mobility of a mobile node, which is registered to a subset of network access entities (NAE). A location update is necessary because the MN moves from a first network area served by the first router to a second network area served by the second router, keeping the same IP addresses. In response to a trigger from the MN, the second router requests from the first router information on the registered NAEs, before they are informed to route data, destined for the mobile node, to the second router. Furthermore, the global IP addresses of the MN, created based on the prefixes of the registered NAEs, are updated. To expedite the address configuration after handover, the second router generates a IP address configuration message for the MN, comprising address prefixes of only the registered NAEs, without prior reception of a router solicitation message.
