The native transport network is a network that naturally carries a subscriber's calls but does not have the capabilities required to provide advanced services. In one embodiment, the system uses a virtual number to map a service in the service-provider network with a device in the native transport network.

The present invention relates to methods and devices that allow for different types of transportation of data packets (6) in conjunction with a home base station (1). Traffic arriving in the home base station (1) from a mobile terminal (2) connected to the home base station (1) can be transported either via a core network (15) of a mobile telecommunications system or by means of local transportation, which implies that the traffic is forwarded to a local node (4) in a local network (20) without passing the core network (15). The home base station (1) examines data packets (6) that are received from the mobile terminal (1) and determines the appropriate type of transportation for each data packet (6). Thus it is not required for traffic that is destined for local nodes (4) to pass the core network (15), which allows for efficient traffic forwarding with several benefits such as offloading the core network (15).

The invention discloses an XinIP cross-broadcast domain data communication method, which achieves mutual communication of hosts with a same IP address field in different networks. Three parameters of a gateway are set, i.e., a proxy address pool, a tunnel local IP address and a tunnel destination IP address. A working principle of the gateway is as follows: when a destination address of a received IP data package is matched with an address in the proxy address pool, a new external IP header is packaged for the data package, wherein a source IP address of the external IP header is the tunnel local IP address, and a destination IP address of the external IP header is the tunnel destination IP address; routing is then carried out; when the destination address of the received IP package is the tunnel local IP address, and the source IP address of the received IP package is the tunnel destination IP address, local transmission is carried out after removal of the external IP header. The method has the advantages that under the premise that working principles of the communication hosts are kept unchanged, the hosts with the same IP address field in the different networks are in a same broadcast domain, so that a traditional protocol for the same broadcast domain can work normally.
