Systems and methods are disclosed for providing a usage monitoring telephony service. A service-providing network, which has the capability of monitoring attributes, including duration, for calls that traverse it, provides usage-monitoring services for calls directed to a telephony device on a native transport network. The native transport network is a network that naturally carries a subscriber's calls but does not have the capabilities required to provide usage monitoring. The system uses a virtual number to map a service in the service-provider network with a device in the native transport network. The usage monitoring services provide a means to capture usage-monitoring data for multiple telephone numbers in multiple native transport networks.

The specification describes a new technique for reducing interference in EDSL signals caused by local BPL transmission lines. It involves sampling the power line signal to derive a noise signal representing the BPL noise causing the EDSL interference, and mixing the BPL noise signal with the EDSL signal to cancel the BPL noise in the EDSL signal. The technique may be implemented by plugging into a conventional home electrical receptacle, and inserting a small noise canceling module in the EDSL line.Since the method involves an attachment only to the EDSL service, it avoids any involvement with BPL service users and providers.

Disclosed is a protocol used by wireless stations sharing a single wireless channel. When a local station senses a communication between remote stations using the channel, the local station estimates whether its local transmissions would disrupt this on-going remote communication. To estimate, the local station forms capture models of the remote stations. From the capture models, the local station determines if its local transmission would prevent each remote station from capturing the signal from the other remote station. If the local transmission would not disrupt the remote communications, the local station transmits its message over the channel at the same time the remote stations use the channel. The local station performs the estimation using parameters of the remote stations. The stations could share their parameters by including them in headers of frames. The protocol can be implemented as an enhancement to the IEEE 802.11 standard.

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.

A method and an arrangement for defining a sub-table structure for SI tables, which may be used to split one big Service information (SI) table into several smaller tables. The splitting into the smaller sub-tables (Sub-Ts) requires less transmitted bandwidth because all the SI do not need to be broadcast to End User Terminal (EUT). Also, the sub-table division enables relatively easy creation of local SI tables because sub-tables can serve as a basis for local Transport Stream (TS) announcement. By dividing tables into smaller ones, the amount of unnecessary information transmitted for the EUT is reduced. The TSs of an entire broadcast network can be divided. Moreover, neighbouring, or adjacent, TSs (cells) can announce and advertise their content to each other, and further to the EUT. A sub-table (Sub-T) of the TS is sent to the adjacent TS. The preferable embodiments enable the EUT for moving in DVB network in a blinded manner being not specially informed about where or under which cell's coverage the EUT is. However, the EUT is able to obtain the information what content (TSs) is locally available because of the sub-table structure.
