Disclosed is method for controlling satellite communication of satellite () flying on trajectory over the earth (). The method comprises providing first target location on surface of the earth; determining trajectory of satellite over the earth; identifying first interference restrictive area (), which satellite trajectory passes; determining elevation angle (δ, δ) in respect to satellite and first target location, wherein elevation angle is angle between horizontal plane of the earth and vector pointing from first target location to satellite along trajectory at given moment of time; and activating first communication beam () from satellite towards first target location when elevation angle is between activation angle (δ) and deactivation angle (δ). Activation angle is less than deactivation angle if first interference restrictive area is located in forward direction in respect to satellite motion along trajectory, and activation angle is more than deactivation angle if first interference restrictive area is located in backward direction in respect to satellite motion along trajectory.

A method and a system for allocating frequency ranges to a plurality of networks. The method includes defining a geographical area. Moreover, the plurality of networks operate in the defined geographical area. The method further includes identifying first frequency parameters associated with each of the plurality of networks in the defined geographical area; determining second frequency parameters for at least one of the plurality of networks based on an event; and allocating the second frequency parameters to the at least one of the plurality of networks for a predetermined period of time.

Disclosed is a method for presenting geographical radio resource usage information in a user interface. The method includes receiving radio resource reservation data including location, time and frequency information stored in an administrative spectrum management system. Furthermore, the method includes selecting at least one area of interest and receiving an input indicating a time period of interest from a user. Moreover, the method includes dividing the at least one area of interest into a plurality of subareas. The method includes calculating for each subarea of the plurality of subareas within the at least one area of interest, a first utilization rate of radio resource over the time period of interest. Furthermore, the method includes defining a color for each subarea based on the calculated first utilization rate. Moreover, the method includes rendering the plurality of subareas with the defined color as a geographical map on the user interface.

A provided apparatus is caused to direct establishment of a connection of the apparatus with a core network via a wide area radio access network (RAN), where the core network is coupled to an external network. The apparatus is also caused to select or receive selection of a local area network that is coupled to the same or different external network via one or more local gateways (L-GWs). The apparatus is caused to request selection of a L-GW of the one or more L-GWs from the core network via the wide area RAN, and in response, receive an identity of a selected L-GW. Further, the apparatus is caused to direct contact with the selected L-GW based on the identity, and establishment of a connection of the apparatus with the selected L-GW. The apparatus may thereby be connected to the external network via the local area network and selected L-GW.

Discovering peer-to-peer content using metadata streams involves capturing, for each of a plurality of devices, a content and metadata stream that describes a context of the content. The metadata streams are sent to a metadata repository contemporaneously with the capture of the content by the respective devices. Network queries of the streaming metadata are enabled via the metadata repository, and, in response to the network queries, peer-to-peer access of the content is facilitated from one or more of the devices.

Discovering peer-to-peer content using metadata streams

Improved systems and methods for establishing peer-to-peer calls such as voice over IP calls and video over IP calls. In various embodiments of the invention, SMTP messages are exchanged between devices using a SMTP server, with the SMTP messages including IP address information. With this arrangement, the need for SIP service providers can be eliminated. In other embodiments of the present invention, SMS messages including IP address information are transmitted between devices during a GSM or other type of telephone call, enabling the call to 'migrate' to a VoIP or video over IP call.

For transmitting delay-critical data in a digital, time division form in an additional channel of a cable television system, the slots of the channel are further divided into smaller mini slots, for the indication of which the same cyclic indication is used as with which the superframes controlling the use of the channel indicate the original slots. A method based on mini slots is compatible with DAVIC 1.0 and 1.1 specifications.

A communications system comprises a central unit () and terminals (). It is equipped so as to establish and maintain a signaling connection between the central unit and at least one terminal using one of at least two alternative signaling protocols. To that end it comprises in the central unit a device for indicating to a terminal the signaling protocols supported by the central unit, and a device for setting up via the central unit's network interface a signaling connection between the central unit's signaling unit and the terminal, using a selected signaling protocol. Correspondingly, in the terminal the system comprises a device for indicating to the central unit the signaling protocol supported by the terminal in response to a message sent by the central unit as well as a device for setting up via the terminal's network interface a signaling connection between the terminal's signaling unit and the central unit, using a protocol supported by the terminal.

The object of the invention is a method for reserving transmission capacity required by the acknowledgement and/or response messages ( ) in a bi-directional transmission system, where a message ( ) is transmitted from a first unit ( ) to a second unit ( ), the second unit ( ) receives the message ( ) transmitted by the first unit ( ), and the second unit ( ) transmits an acknowledgement and/or response message ( ) as a response to the received message ( ) so that the reservation of the transmission capacity required by the acknowledgement and/or response message ( ) is made substantially in connection with the transmission of the message ( ) transmitted from the first unit ( ) to the second unit ( ). An object of the invention is also a system for reserving transmission capacity required by the acknowledgement and/or response messages ( ) in a bi-directional transmission system, whereby the transmission system comprises at least a first unit ( ) having means for transmitting and receiving a message ( ), and a second unit ( ) for receiving the message ( ) and for transmitting acknowledgement and/or response messages ( ), and the first unit ( ) and/or the second unit ( ) have means for making the reservation of transmission capacity required by the acknowledgement and/or response message ( ) substantially in connection with the transmission of a message ( ) transmitted from the first unit ( ) to the second unit ( ).
