Abstract: A method for establishing a TCP connection between two client terminals protected by stateful firewalls and comprising means for sending messages to each other via a messaging server. The client terminals agree on establishing a mutual TCP connection by sending a message, which indicates port numbers to be used on said connection. A TCP connection establishment procedure is started in both client terminals. After sending a first handshake message, a message indicating a sequence number of the first handshake message is sent from both client terminals to each other. When the firewalls of the opposite client terminals reject the first handshake message, an acknowledgement message to the first handshake message is created in both client terminals using a raw socket, which acknowledgement message includes the received sequence number as an acknowledgement number. Finally, the raw socket based acknowledgement message is sent to the opposite client terminal for completing the establishment of the TCP connection.

Abstract: In response to a request initiated by a user at a user terminal, selected entertainment programming content, when broadcast, is recorded at a location remote from the user terminal. The request is communicated through a communications network, e.g., cable TV network, which is also used for transmission of entertainment programming content to user terminals. The recorded programming content is stored in a storage space at the remote location, which is allocated to the user terminal. In response to a review request from the user terminal, the recorded programming content is retrieved from the storage space allocated thereto, and transmitted to the user terminal through the communications network. The presentation of the recorded programming content may be manipulated by the user to perform rewinding, pausing and fast-forwarding thereon.

Abstract: A communication terminal optimally switches between the use of multicast reception and unicast reception, in consideration of the mobile radio environment of each terminal. For example, received signal strength indicator information is acquired at a received signal strength indicator information acquisition time calculated using a content reception time. Either multicast reception or unicast reception is selected according to the acquired received signal strength indicator information and content reception is performed. An optimal reception system can be selected and reception failure can be reduced. In addition, by performing a dynamic switching of reception methods as such, the base station-end can perform multicast delivery rather than unicast delivery when possible to communication terminals in favorable mobile radio environments, thereby significantly reducing the traffic load placed on communication paths.

Abstract: A method for configuring SIP settings to a user terminal, for instance when a specific SIP service is used in the user terminal for the first time, includes transmitting a request message from the user terminal to a gateway node. As the request message is received in the gateway node, the gateway node retrieves identification information on the user terminal. After that the request message and the retrieved identification information are forwarded from the gateway node to a settings server. In response to receiving the request message and the identification information, the settings server defines service-specific SIP settings for the user terminal, and the defined SIP settings are provided to the user terminal.
