摘要： A time-shift TV (TsTV) service establishment method and a TsTV media function (MF) entity are configured to realize TsTV services in an IP Multimedia Subsystem (IMS) network. The method includes the following steps. The TsTV MF entity receives a media negotiation including content delivery channel information and content control channel information initiated by a terminal, establishes a transmission connection with the terminal based on the media negotiation result, receives a media playing request sent from the terminal through the transmission connection, and sends media information corresponding to the media playing request to the terminal through a content delivery channel established based on the content delivery channel information. A TsTV MF entity is also provided. Thus, the TsTV services are realized in an IMS network.
摘要翻译：时移电视（TsTV）服务建立方法和TsTV媒体功能（MF）实体被配置为实现IP多媒体子系统（IMS）网络中的TsTV服务。该方法包括以下步骤。 TsTV MF实体接收包括由终端发起的内容传送信道信息和内容控制信道信息的媒体协商，基于媒体协商结果与终端建立传输连接，通过传输连接接收从终端发送的媒体播放请求并且通过基于内容传送信道信息建立的内容传送通道向终端发送与媒体播放请求对应的媒体信息。还提供了一个TsTV MF实体。因此，TsTV服务在IMS网络中实现。

摘要： The present invention provides a method for providing message transmission in H.323 communication system. The method includes: the first endpoint and second endpoint confirming authentication information through a GK; according to said authentication information, the first endpoint and second endpoint exchanging message directly. Since H.235 protocol of ITU-T describes the authentication and privacy technique used in H.323 systems and provides security service for message transmission in GK-routed model, the present invention can guarantee the security of the authentication information. The functions of middle entities need not to be modified for applying the method provided by the present invention because Diffie-Hellman key exchange technology is adopted in this method. The present invention increases the network scalability of the symmetric key system by adopting negotiation mode. The present invention designates and improves the security framework of message transmission in direct-routed model of H.323 system, thereby improving the security of H.323 system.

摘要： A method for controlling authorization of service resources includes: by a Proxy Call Session Control Function (P-CSCF) entity, receiving a message that carries a list of resources allowed to be used from an SCF entity; and obtaining the list of resources allowed to be used from the message, and controlling authorization of resources requested by a User Equipment (UE) according to the list of resources allowed to be used. A system and device for controlling authorization of service resources are also disclosed. With the present invention, the services accessible to the user are authorized at a single attempt. Therefore, the service switching speed is increased without any impact on the flexibility of the user in selecting the list of accessible services; and the service availability and the user experience are enhanced significantly.
