摘要： The present invention relates to a communications system for handling communications sessions, for example multimedia calls or voice calls. The communications system comprises a local terminal, an external server, a proxy interface agent (PIA) between the terminal and a shared network. The communication means includes a NAT function through which the communications session must pass. The communications session is carried over the network over one or more logical channels between the terminal and the external server, during which the first NAT function applies network address mappings on the terminal's transport addresses. The PIA acts on behalf of the terminal in communications with the external server, and establishes a logical channel on an outbound connection to the server that serves as a control channel between the PIA and the server. The PIA establishes dynamic outbound connections to the server, and in response to a request from the server or in response to a request from the PIA itself, makes one or more associations between the terminal's transport address(es) and identifiable logical channel(s) between the PIA and the server. These identifiable logical channel(s) are established on one or more of the dynamic outbound connections from the PIA to the server.

摘要： The present invention relates to the communication field, and discloses an information synchronization method, apparatus and system are provided, which solves the problem of address conflict occurring when two local area networks use an UPnP protocol to perform communication. The method includes: acquiring declaration information of a first local area network device that is in a first local area network, where the declaration information includes a private address of the first local area network device in the first local area network; mapping the private address of the first local area network device into a corresponding external address according to a preset mapping relation between private addresses and external addresses; and sending a notification message carrying the external address of the first local area network device to a second local area network, so as to enable the second local area network to store the external address of the first local area network device and notify a state of the first local area network device to a second local area network device in the second local area network. The technical solution provided in the present invention is applicable to an UPnP remote access.

摘要： A method is provided for resolving a collision of Internet Protocol (IP) addresses between devices connected to a first server and a second server remotely accessed in a Universal Plug and Play (UPnP) remote access service. The second server receives address information of a network of the first server from the first server. The second server compares address information of a network of the second server with the received address information of the network of the first server, and determines whether a collision has occurred between addresses of the first server and the second server. A collided address is changed when the collision has occurred.

摘要： The system provides a low cost way of providing high speed point to point communications between two offices, as well as Internet access, which exploits the use of low cost access technologies, such as ADSL, in such a way that (a) no CO component is required to deploy the solution, (b) the two offices could have different types of communication technologies available, and (c) more than two offices can form an overlay network, whereby each pair of offices has a virtual single high throughput pipe available which is achieved through aggregation of Internet access services at each office. The proposed system allows intranet communication links or Internet connections to be aggregated, thereby enabling faster and more reliable communications.

摘要： The invention relates to procedures and devices for routing of a data packet from a first device in a first network segment to a second device in a second network segment. The data packet includes a first address in a receiver address field and a first port number in a receiver port field. According to the invention a second port number which in the second device is uniquely associated with the first address is allocated. The data packet is modified by the first address in the receiver address field being replaced with the address of the second device and by the first port number in the receiver port field being replaced with the second port number. The modified data packet then is transmitted from the first device to the second device. In the second device the first port then be identified by means of the second port number that the modified data packet is associated with the first address. The modified data paacket then can be restored by the address of the second device being replaced with the first address.

摘要： Transmission system for train vehicles, comprising in each vehicle transmission devices which are interconnected by a transmission path (e.g. a bus). Electrical devices (e.g. display devices) are connected to the transmission devices and exchange data therewith. A transmission relay control device of each transmission device automatically allocates an address to the connected electrical device. The addresses could be created based on the host transmission device address itself, or they represent default addresses. In a second embodiment, the transmission devices comprise an address conversion device.

摘要： Systems and methods are disclosed for mitigating addressing conflicts in joined networks (18, 19). For example, Internet Protocol (IP) addressing conflicts in a virtual private network (VPN) can be mitigated by automatically changing an address of a gateway (11, 15,...) of one network when another network is placed in communication therewith. A destination network address translation (DNAT) filter can be used to direct packets to the new address of the gateway (11, 15,...).

摘要： A local network connecting system includes a first local network (100), a second local network (200), a Mobile terminal (1). The first local network (100) comprises a gateway (2) and a first server (6) assigned with a first local address. The second local network (200) comprises a second server (7). The Mobile terminal (1) is connected to the second server via a VPN -"Virtual Private Network"- through the first local network. The gateway provides mapping of local addresses for a terminal connected to the first local network (100). When a packet is sent to the first server from the Mobile terminal (1), the Mobile terminal (1) uses a second local address unused in the VPN and the second network as destination address of the packet instead of the first local address, and transmits the packet to the gateway (2). The gateway (2) translates the second local address into the first local address as destination address of the packet, and transmits the packet to the first server based on the translated destination.
