Abstract: Advice of charge information is provided utilizing the session initiation protocol (SIP) in an Internet protocol multimedia subsystem without utilizing an application server. The advice of charge message is provided to a user via the serving call/session control function and the home subscription server. When a request for a service is received by the serving call/session control function, the state of a binary, Boolean flag associated with the originator of the request is analyzed. Depending upon the state of the flag, either the request is routed to its intended destination, or an advice of charge message is routed to originating user, advising the user of the charge for the requested service. If the user accepts the charge, the serving call/session control function transmits the request for routing to the intended destination, and the flag is toggled. If the user declines the charge, the call is ended.

Abstract: A system and a method for a Mobile Host (MH) implementing a multicast service, wherein each MH corresponds to a Dynamic multicast Agent (DMA); the DMA needs to implement dynamic switch according to the path that the MH passes when moving; if the DMA of the MH is switched to the MSA of the current multicast sub-network, the MH joins the multicast group directly, thereby optimizing the transmission path of the multicast. The present invention can not only make the multicast distributing tree reconstruction caused by moving of the MH less frequent, but also avoid a too long tunnel form between the DMA and the MSA of a foreign multicast sub-networks, thereby optimizing the transmission path of the multicast packet. The present invention can also make the best use of network resources, and prevent the DMA from becoming the bottleneck of network communication while avoiding tunnel congregation.

Abstract: An edge router (6) for multicast data transfer comprises a cache (10). In response to a request for a file from a host (3a), the router (6) retrieves the file from a content provider (2). The file, comprising data packets A-G, is stored in the cache (10) before transmission to host (3a) to allow the receipt of requests for the same file from other hosts (3b, 3c). A timer is activated to count down through a predetermined waiting period T. A file delivery group is defined, comprising host (3a). Any other hosts (3b, 3c) located in the same cell as host (3a), requesting the same file during period T are added to the group. When a predetermined number of requests have been received or, alternatively, when the waiting period T expires, the file is retrieved from the cache (10) and forwarded to the hosts (3a, 3b, 3c), in the group.

Abstract: Media that is normally packetized into many separate individual packets and then queued for individual transmission during a transmit window is combined together into one, or a few, packets. The larger packets more efficiently carry media over a time slotted communication media since only one, or a few, packet headers are used for carrying a larger amount of media. Since packets cannot be transmitted until the start of a new transmit window, the larger packets do not substantially add to the overall packet delay that normally occurs when larger packets are formatted and transmitted in non-time slotted networks. In another aspect of the system, probe packets are used to identify the start of the transmit window. The transmit window start time is inferred from the round trip times for the probe packets and media packetization is then synchronized with the identified transmit windows.
