  • Patent number: 9185579
    Abstract: A network device receives probe packets communicated by a user equipment device. The network device communicates response packets back to the user equipment device, including timestamps, and/or other information. The user equipment device may be configured to test the performance of different portions of a wireless network (i.e., determine an available bandwidth measurement throughput (ABMT) of the wireless network) by accessing different network devices (or information associated with different network devices).

  • Patent number: 8391912
    Abstract: The present invention is directed to a method for predicting a bit rate provided by an enhanced data channel in a future radio channel, once the future radio channel is added to an ordinary data channel in an operational radio channel. It is assumed that the bit-rate provided by the enhanced data channel is indicated by the ratio (A), wherein E is the enhanced data channel power offset, E is the ordinary control channel power offset after a future addition and k1 is a constant. The method comprises with respect to the operational radio channel the steps of obtaining a first transmit power P1, a first quality target Q1, the power offset O for an ordinary control channel and the power offset O for the ordinary data channel. In addition, the method comprises with respect to the future radio channel the steps of obtaining a second transmit power P2 and a second quality target Q2.

  • Publication number: 20040116123
    Abstract: The present invention relates to an apparatus and a method for measuring interference levels in a telecommunication system comprising a radio base station communicating with at least one in-house mounted transceiver, the transceiver defining a communication range in which it is responsible for handling, communication terminals, such as mobile phones or computer terminals. By means of at least one scanner the apparatus synchronises with transmitted information from the base station to the transceiver in a time regime. The scanner is connected to measurement means for measuring the interference level on transmitted information and the measurement means is adapted to compare measured interference levels with each other an thereby improve transmission between the base station and the transceiver on a favourable frequency, whereby the problem of interference on allocated traffic channels is alleviated.

  • Publication number: 20030126193
    Abstract: In a management system comprising a manager connected to a number of agents a trap table is provided in the agent. Each trap transmitted from the agent to the manager is given an incremented number so that if the manager does not receive a trap, the manager knows which trap to request from the agent using an SNMP get-request message. The information of the trap message can then be fetched from the trap table in the agent and transmitted in a response message to the manager. A trap counter is also provided in the agent. The trap counter is set equal to the number of the last sent trap in connection with the sending of the trap.

  • Patent number: 5960355
    Abstract: The present invention teaches a method, system, terminals and service node for geographically positioning a first mobile radio terminal (MS1) within a radio network (100) comprising unsynchronised radio base stations by using a plurality of second fixed radio terminals (MS2) whereby the positions of the radio base stations and the second fixed radio terminals are known. First and second radio terminals (MS1,MS2) measure the relative receive times between the timing signals downlink (113-118) received from at least three radio base stations (BS1,BS2,BS3) and the second fixed radio terminals (MS2)send them to a service node (107) in the network (100) using them for calculating the transmission time offsets of the timing signals downlink.
