| 20110170445 | METHOD AND ARRANGEMENT FOR DETERMINING TRANSMISSION DELAY DIFFERENCES - The invention relates to determining mutual differences of transmission delays experienced by protocol data units transmitted in a communications network. This invention is based on a surprising discovery that the time difference between the receiving moments of protocol data units the temporal receiving order of which deviates from their temporal transmitting order represents the smallest possible difference between the transmission delays experienced by these protocol data units. In a method according to the invention it is determined, based on an order indicator associated with a protocol data unit received at an earlier point of time and an order indicator associated with a protocol data unit received at a later point of time, whether the mutual order of the protocol data units changed during transmission. If the mutual order has changed, the time difference between the receiving moments of the protocol data units is calculated, which time difference represents the smallest possible difference between the transmission delays experienced by these protocol data units. | 07-14-2011 |
| 20110064047 | METHOD AND SYSTEM FOR TRANSFERRING A COMMUNICATION SESSION BETWEEN DATA SOURCES - To transfer a communication session from a first data source to a second data source, the following operations are carried out when a radio terminal is handed over from a first base station to a second base station: the session settings and status information related to the communication session are transferred ( | 03-17-2011 |

| 20100183036 | METHOD AND ARRANGEMENT FOR ADJUSTMENT OF A CLOCK SIGNAL - An arrangement for adjusting a clock signal in a network element of a communications network includes a processor device arranged to produce a control variable containing information about synchronization messages received from at least two other network elements. A situation in which the reception from a sending network element of synchronization messages of a good enough quality ceases will not significantly disturb the clock signal to be adjusted because only part of the control variable used for the adjustment depends on synchronization messages sent by an individual network element. In a preferred arrangement, the reference value of the control variable is changed in response to a situation where the reception from a sending network element of synchronization messages of a good enough quality ceases. Thus it is possible to reduce the change of the difference between the control variable and its reference value which further reduces disturbances caused in the clock signal to be adjusted. | 07-22-2010 |
| 20100177702 | METHOD, SYSTEM AND INSTALLATION FOR FORWARDING DATA TRANSMISSION FRAMES - In a system, the functionality is decentralized in a data transmission network so that the need of communications produced by and addressed to data terminals to pass by way of a single point in the data transmission network is diminished. A first data transmission installation is adapted to signal second data transmission installations, each of which is part of a ring-shaped data transmission topology, to be capable of building logical data transmission tunnels directed to the data terminals. Thereby, all the logical data transmission tunnels need not commence or, depending on the direction, terminate at the same point of a data transmission network. In addition, the data transmission installations present in a ring-shaped data transmission topology need not necessarily be taught routing information in order to enable each of these data transmission installations to send data transmission frames to be transmitted to another one of these data transmission installations. | 07-15-2010 |
| 20100110990 | METHOD AND DEVICE FOR FORWARDING DATA TRANSPORT FRAMES - In a data communication system according to the invention the functionality of the gateway device is distributed in a data communication network thereby reducing the need to direct the data traffic from and to terminals ( | 05-06-2010 |

| 20090022051 | ADJUSTING THE DEGREE OF FILLING OF A JITTER BUFFER - A method and arrangement for adjusting the degree of filling of a jitter buffer in a network element receiving digital data. To the jitter buffer, there is connected a read-out unit for reading digital data from the jitter buffer. In the method, there is composed a time reserve indicator for the received protocol unit, the time reserve indicator being essentially the difference of an order indicator connected to the protocol unit and an order indicator connected to the operational cycle of the read-out unit. The time reserve indicator of the protocol unit indicates whether the protocol unit was received in good time, in order to ensure that the digital data is in the jitter buffer when the digital data is in turn to be read out. The degree of filling of a jitter buffer is adjusted on the basis of time reserve indicators composed for the received protocol units. | 01-22-2009 |
| 20090013126 | METHOD AND DEVICES FOR COMPRESSING DELTA LOG USING FLASH TRANSACTIONS - Each received piece of configuration data is added at a next currently free location in a volatile buffer. The contents of the volatile buffer are compressed after adding each received piece of configuration data. The compression result is stored in a non-volatile flash memory. If the compression result was shorter than a limit, it is allowed to be overwritten in the flash memory by a next compression result. If the compression result was longer than the limit, it is stored in the flash memory and the next compression result is directed to a different location in the flash memory. | 01-08-2009 |
