  • Patent number: 7742418
    Abstract: The technology in this application determines the throughput over a data communication substantially as experienced by a user receiving the data. The determined throughput is substantially independent of the total amount of data transferred over the connection. This “active” throughput measure is divided into two parts to provide two performance measures: transfer throughput and latency. Latency corresponds to a time period needed to accomplish one or more functions associated with the data connection, like setting up and taking down the connection, during which payload type data to be transferred to an end user is not transferred. By identifying and removing the initial latency from the throughput determination for the data connection, the determined transfer throughput provides a more accurate measure of the throughput actually experienced by the end user.

  • Publication number: 20090323965
    Abstract: Monitoring the performance of communication systems is an important part of network operations. In one aspect the invention provides a method for monitoring the performance by collecting data pertaining to a mobile terminal accessing the system. In some embodiments, the method includes receiving an identifier for identifying the mobile terminal; using the identifier to detect the UE accessing the network via an access point; and in response to detecting the UE accessing the network, transmitting to the access point a message comprising an encrypted version of the identifier with a command to initiate the collection of data pertaining to the mobile terminal.

  • Patent number: 6847651
    Abstract: A method for communicating packet data units in a radio communication system having a first base station that supports both speech and data packet communication with a number a radio units, wherein the first base station includes a first transceiver unit communicating a speech call with a first radio unit on a speech traffic channel mapped on a first basic physical channel, and where a discontinuous transmission mode can be activated on the first speech traffic channel, characterized in that the method comprises the step of communicating packet data units between the first transceiver unit and a second radio unit on a packet data channel mapped on a second basic physical channel when the discontinuous transmission mode is activated on the first speech traffic channel.

  • Patent number: 6546255
    Abstract: The present invention relates to a method in a cellular mobile communication system for transmitting Pages, and such a system. The cells of the system are subdivided into two classes. To which class a cell is assigned is decided by its capacity to transmit Pages or by the amount of Page responses received within the cells. When paging a mobile station, the Page is first transmitted in the cells of the first class. If no response is received to that Page, the Page is transmitted also in the cells of the second class. An advantage is that there will be fewer Pages congested due to lack of capacity for transmission. Transmitted Pages in the cells of the second class are primarily transmitted to mobile stations that are really present within those cells. Thereby the probability increases that all mobile stations will be reached by Pages intended for them.
