摘要： This invention concerns a process and a system for providing location information for a wireless unit in a wireless network to a location-based service provider, using a data network. In particular, the location information is provided to the location-based service provider without necessarily providing the identity of wireless unit, e.g., a subscriber's wireless identification number, to the service provider. In this regard, a subscriber's identification number may be hidden from the positioning service provider via a process in which an alias is used instead of the subscriber's normal identity. The subscriber's number may further be concealed from the service provider via a process wherein encrypted information is used instead of the subscriber's normal identity.

摘要： A method and system of operating a Reliable Transmission Protocol switch node to provide an IPTV multicast is provided. According to an embodiment of the invention, IP packets transporting an encrypted media stream are received from an IPTV Head-end. The media stream contains complete image frames. Unencrypted identifiers identifying packets containing complete image frame data are also received. The received packets are stored in a buffer, and on receipt of a request from a media renderer to provide the IPTV multicast, the packet(s) containing the last complete image frame in the media stream and all subsequent packets are sent to the media renderer.

摘要： The present invention relates to methods and arrangements for providing an improved channel change solution for and IPTV system. This is achieved by sending an additional FCC (Fast Channel Change) media stream using multicast from a fast channel change server. The FCC media stream contains a stream being a copy of the main stream wherein the speed is higher than the speed of the main stream. The FCC media stream may start with an I or S-frame and a number of STBs can use the same FCC multicast stream.

摘要： A multimedia provider multicasts a main multimedia stream comprising a mixture of intra and inter frames and multicasts an associated auxiliary stream comprising intra frames. At least a portion of the intra frames in the auxiliary stream are generated based on same multimedia data as at least a portion of the inter frames of the main stream. The provider also transmits a stream information channel comprising information descriptive of time instances of intra frames in the main and auxiliary streams. This information allows a set top box to selectively connect, in connection with session set-up and channel switch, to the main or auxiliary stream to receive an intra frame with as a low delay as possible.

摘要： A method of setting up a session between a client terminal and a media supply system in order to transport a unicast media stream from the media supply system to the client terminal over an intervening IP network, the media supply system implementing the Real Time Streaming Protocol. The method comprises conducting a negotiation between the client terminal and the media supply system over an IP Multimedia Subsystem network in order to identify to the IP Multimedia Subsystem network the source and destination IP addresses and port numbers for the media stream, and subsequently sending Real Time Streaming Protocol messages from the client terminal to the media supply system in order to control the playout of media from the media supply system.
摘要翻译：一种在客户终端和媒体供应系统之间建立会话的方法，以便通过中间IP网络将媒体供应系统的单播媒体流传输到客户终端，媒体供应系统实现实时流协议。该方法包括通过IP多媒体子系统网络在客户终端和媒体供应系统之间进行协商，以便向IP多媒体子系统网络识别媒体流的源和目的地IP地址和端口号，并且随后发送实时从客户终端向媒体供应系统流式传输协议消息，以便控制从媒体供应系统播放媒体。

摘要： A method and nodes in a communication network for controlling multi-cast delivery of files, wherein the multi-cast delivery is adapted to reduce the amount of required uni-cast file deliveries in the communication network. A browser of an IPTV Terminating Function requiring a file interrogates a cache of the IFT for the file content before a uni-cast request for file delivery is sent to an Application Service Platform. The files stored in the cache have been previously delivered to the IFT via the proposed multi-cast mechanism. If the file content is not stored in the cache, a uni-cast request is sent to the ASP. Each uni-cast request is also forwarded to a Multi-Cast Controller, which determines whether the requested file should be sent also to a plurality of additional IFTs on a multi-cast channel. At each IFT, listening to the multi-cast channel, the received content can be handled selectively according to a filtering mechanism, and a received file may, e.g. be stored in the cache for later retrieval.
摘要翻译：用于控制文件的多播传送的通信网络中的方法和节点，其中所述多播传送适于减少所述通信网络中所需的单播文件传送量。要求文件的IPTV终止功能的浏览器在将文件传送的单播请求发送到应用服务平台之前询问文件内容的IFT的高速缓存。先前通过提出的多播机制将存储在缓存中的文件传送到IFT。如果文件内容未存储在缓存中，则会将单播请求发送到ASP。每个单播请求也被转发到多播控制器，多控制控制器确定所请求的文件是否也应发送到多播信道上的多个附加IFT。在每个IFT，监听多播信道，可以根据过滤机制选择性地处理所接收的内容，并且所接收的文件可以是例如。存储在缓存中以供以后检索。
