Problems solved by technology

Since the coverage of broadcasting is somewhat inherently limited to the geographical area, this does not provide for the selection of destination terminals using selected criteria and in particular the possibility of conducting location-specific communications, i.e. selecting a geographical area for communications

Embodiment Construction

[0015] exist figure 1 In the preferred embodiment of the invention shown, the communication system utilizes the Internet backbone, but the invention can also be used in other embodiments in which datagrams are sent over other networks. figure 1 The network communication system shown includes IP subnets 1 through 5, defined by common elements of Internet addresses assigned to them (bits for IPv4 or prefixes for IPv6), subnets 1 through 5 are separated from the Internet backbone by simple routers or gateways separated from the network. According to an embodiment of the present invention, corresponding subnet proxy servers 7 to 11 are associated with subnets 1 to 5 . Subnet proxy servers 7 to 11 are preferably directly connected to subnets 1 to 5 without routers; this can use the "all nodes" address of the IPv6 protocol to communicate with all nodes in the subnet. User terminals such as 12 to 19 communicate with IP subnets 1 to 5 .

Abstract

A method of, and apparatus for, communication of datagrams over a network comprising sub-networks (1 to 5) served by respective sub-network servers (7 to 11) from a sender terminal (15), especially a mobile terminal communicating over a wireless link, and a plurality of destination terminals (12 to 19) served by a plurality of said sub-networks (1 to 5), in which the datagrams are routed using destination identifications contained in the datagrams. A sub-network grouping server (20) selects a plurality of the sub-network servers (1, 4) and provides communication of datagrams between the sender terminal (15) and destination terminals (12, 13, 16) within the corresponding selected sub-networks (1, 4), the selection being made according to criteria, such as geographic position, chosen as a function of information derived from the sender terminal (15) without the individual destination identifications of the destination terminals (12 to 19) being specified by the sender terminal (15).

Description

technical field [0001] The present invention relates to the communication between terminals in multiple subnets of a network. The data messages in the network are routed using the destination identification included in the data messages, especially (but not limited to) the terminals using the IP (Internet Protocol) protocol addressing situation. The present invention is applied to the situation where the subnet is divided according to geographical location, and the subnet is described by using this division, but the embodiments of the present invention are also applicable to the situation where the subnet is divided by other standards. Background technique [0002] Various methods exist for selectively communicating between a terminal and other terminals in a network, where the terminal is addressed using Internet Protocol (IP), including broadcasting and multicasting. [0003] The most common type of IP communication is unicast (unicast) communication, that is, communicati...
