| 20090103548 | Method for transmitting data in a communications network and transmit device and receive device for a communications network - According to the invention, data are transmitted by means of a data frame in a communications network from at least one subscriber connected to a communications network to at least one other subscriber similarly connected to the communications network, wherein the data are prepared for transmission in such a way that information for identifying or distinguishing the respective format of the data within a data frame is written into a field directly at the beginning of a data frame or into a field introducing a data frame. | 2009-04-23 |
| 20090103549 | TELECOMMUNICATION AND MULTIMEDIA MANAGEMENT METHOD AND APPARATUS - The present invention is directed to a method for transmitting data over a network. The method includes ascertaining at a first node the need to transmit one or more data streams from the first node to a second node over the network, the one or more data streams including time-based media that is generated either locally or remotely on the network. The method also includes ascertaining at the first node a timeliness preference for reviewing the one or more data streams by one or more recipients respectively. The ascertained timeliness preference for each one of the data streams is either (a) time-sensitive where at least one recipient of the one data stream has indicated an intent to review the one data stream in a near real-time mode as received by the recipient over the network while the time-based media of the one data stream is being generated or (b) less-than time-sensitive. In accordance with the method, one of several transmission techniques is used to transmit the data streams, depending on the ascertained timeliness preference of each data stream. Either a first transmission technique is used for the less-than time-sensitive preference data streams or a second transmission technique is used for data streams with the time-sensitive preference. The first technique uses a larger first packetization interval, which is defined as the amount of time based media contained in each packet, compared to the second packetization interval used by the second technique. | 2009-04-23 |
| 20090103550 | IP network system - There is provided an IP network system. The IP network system includes: a plurality of relays making up a ring network; a source host for transmitting a packet and connected to the ring network; and a destination host which conducts a packet communication with the source host through the ring network. Each of the relays is operable to transfer received packets containing a transfer direction information to the destination host through a right-handed route of the ring network and through a left-handed route of the ring network, based on the transfer direction information. | 2009-04-23 |
| 20090103551 | MEDIA GATEWAY AND PACKET FILTERING METHOD THEREOF - A media gateway (MG) and a packet filtering method thereof are provided to enhance the adaptability of the packet filtering mechanism on the MG. The packet filtering rule for a service instance may be changed dynamically, namely, the MG analyzes the currently transmitted packets of a service instance, obtains the state change of the instance, and then dynamically changes the packet filtering rule of the instance according to the state change of the instance. The present invention extends the property parameters of the H.248 protocol or MGCP protocol and adds a property parameter that indicates the dynamic packet filtering function is enabled or disabled and a property parameter that indicates the service type so that the MGC can enable or disable the packet filtering function for the instance of the specified service type flexibly according to the values of such parameters. | 2009-04-23 |
| 20090103552 | METHOD, APPARATUS AND SYSTEM FOR A MEDIA GATEWAY CONTROLLER TO DELIVER A RESOURCE PROVISION DECISION TO A MEDIA GATEWAY - A method for a media gateway controller (MGC) to deliver a resource provision decision to a media gateway (MG) includes: the MGC receives a decision request from the MG and makes a resource provision decision according to service requirement information and/or resource status information, and delivers the resource provision decision to the MG. The present invention also discloses an MGC, an MG and a system comprising the MGC and MG In the invention, the MGC does not deliver the resource provision decision already made according to service requirement information and/or resource status information until reception of a decision request from the MG so that the MGC delivers a resource provision decision passively upon request of the MG. The Pull mode for delivery of the resource provision decision is thus supported. | 2009-04-23 |
| 20090103553 | METHOD, SYSTEM AND DEVICE FOR INSTRUCTING MEDIA GATEWAY TO SET UP TERMINATION CONNECTIONS - A method for instructing a media gateway to set up termination connections is disclosed in embodiments of the present invention. The method comprises: acquiring by a media gateway controller, MGC, information on connection capability, of a media gateway, MG, for various types of terminations; and when a calling connection is required, transmits from the MGC to the MG the connection indication carrying termination connection information that the MG has connection capability, according to the information on the MG's connection capability for various types of terminations. Embodiments of the present invention can ensure that the MG can effectively implement termination connection operation, so as to ensure a smooth progress of a calling connection process and greatly improve quality of service. | 2009-04-23 |
