摘要:
Apparatus for determining a protocol of messages traversing a signalling link in a telecommunications network includes a memory for storing one or more predetermined characteristic of a message in the protocol that can be used to distinguish that protocol from other protocols. A protocol auto-discovery module is coupled to the memory and to a module that extracts channels from signalling link timeslots. The protocol auto-discovery module determines whether the predetermined characteristic is present in the sampled message and identifies the signalling link as carrying messages in the particular protocol if the predetermined characteristic is present in the sampled message. The identification may be based on a confidence measure stored in a channel configuration table which is incremented when a message on the signalling link is identified as being in that particular protocol and decremented when a message is identified as being in another protocol.

A method of categorising speed of a terminal (202) in a wireless communications network (116) comprises monitoring a first factor associated with allocation of a radio-frequency (RF) resource that is not related to mobility of the terminal (202). The first factor is then offset against a second factor, the second factor being potentially indicative of mobility of the terminal (202). The speed of the terminal (202) is then approximated using the result of offsetting the first factor against the second factor.

摘要:
In order to discover at least part of a frequency list used by an active wireless device in a cellular communications network for neighbour cell signal measurements, measurement reports are extracted from messages carrying reports of measurements relating to propagation of wireless signals between the network and the device. Additional information (such as identity of sections of the network adjacent to a current serving cell for the device) is extracted from other messages, and the extracted measurement reports and additional information are combined to discover the required frequency list.

Apparatus and method for testing of a telecommunications network, which uses a passive monitoring system to generate actual customer usage data concerning the telecommunications network. An active test manager uses the actual customer usage data to instantiate a set of test templates from a store of predetermined test templates, the test template describing a sequence of user actions performed in the network. The test templates include at least one test variable, which is updated by the active test manager, using the actual customer usage data, to generate a test, or set of tests. The generated test, or set of tests are then used by an active testing module to actively test the telecommunications network, hence the tests are updated using the latest data on customer usage.
摘要:
Call detail records are generated for usage of a telecommunications service established in a telecommunications network, by monitoring messages in a signalling system for co-ordinating operation of the network and carried over signalling links in the signalling system between a service switching function entity and a service control function entity. Messages are selected that relate to instances of usage of the telecommunications service initiated by the service switching function entity to at least one signal switching point in the network. These selected messages are correlated in accordance with the usage instance to which they relate, and information in the correlated selected messages is used to derive a call detail record for an instance of usage of the telecommunications service.

摘要:
Synchronisation of signal measurement reports in a mobile communications system is monitored by monitoring signalling messages traversing a signalling link and containing measurement reports of signals exchanged by a base station and a mobile station, deriving from the measurement reports a first indication of reporting of a first operational parameter of the exchanged signals, deriving from the measurement reports a second indication of reporting of a second operational parameter of the exchanged signals, and comparing the first and second indications to determine whether signal measurement reports are synchronised.
摘要:
A method is disclosed for operating a synchronous Code Division Multiple Access (S-CDMA) radio frequency communication system having a host transceiver unit and a plurality of user transceiver units. The method includes an initial step of defining a super-frame to be comprised of N sequential frames of data. In the preferred embodiment N is equal to three. For a user transceiver unit that obtains access to the host transceiver unit a next step of the method receives frames of data transmitted by the host transceiver unit and initially aligns a receiver timing and a transmitter timing of the user transceiver unit to a super-frame boundary of the received frames. A next step transmits frames of data from the user transceiver unit to the host transceiver unit using the initial timing alignment. A further step of the method detects at the host transceiver unit a difference between the arrival of the transmitted frames of data and a super-frame boundary and then transmits a timing correction parameter, preferably expressed in symbols, from the host transceiver unit to the user transceiver unit in order to align the transmitted frames of data to the super-frame boundary.
