Abstract: A management system for managing the operation of network elements in a mobile communications system, the management system comprising: a manager agent entity being capable of sending a request for the network element to measure a parameter indicated by a target to obtain a plurality of measured parameters and being capable of sending an achievement indication element related to the target; and an agent entity being capable of receiving the achievement indication element and being capable of determining a target achievement indication in respect of at least one measured parameter, the target achievement indication having been determined as a result of monitoring the correspondence between the target and the at least one measured parameter.

Abstract: A method of determining geographical determination of coverage in a mobile communications system by obtaining measurement data provided by a plurality of mobile terminals the method comprising the steps of: requesting terminal capability information from the subscriber terminals in a cell; obtaining the terminal capability information from the subscriber terminals; comparing the terminal capability information with capability requirement information; selecting selected subscriber terminals on the basis of their capability information; sending a trace activation command to the selected subscriber terminals; and receiving measurement data measured by the selected subscriber terminals.

Abstract: Embodiments of the invention include methods, apparatuses, systems and computer programs related to providing a cell traffic trace functionality in E-UTRAN. A cell trace activation message is received, a cell traffic trace session is then started for a cell, and call set up is started. A trace recording session is started and, simultaneously, a unique identifier is generated for the recording session. A trace notification may then be sent to a core network or mobility management entity. The trace notification may include a trace recording session reference which comprises the unique identifier for the recording session. The IMSI and/or IMEI may also be determined for the call, and the trace recording session reference is forwarded to a trace collection entity.

Abstract: A method for tracing a session or call in a network environment, comprising the step of transmitting a trace invocation from a control plane network element to another control pane network element or a user plane network element. According to a first aspect, a trace report is generated in the S-CSCF of the called party. This overcomes the lack of being able to provide detailed information about the interworking between the User Equipment (UE) and the IMS, in setting up IP multimedia sessions. According to a second aspect trace reports are generated in all the network functions involved in session setup.

Abstract: Automated central trace management in a communication network including a network managing entity and at least one subordinate network entity, comprising the steps of activating a trace session locally at the at least one subordinate network entity and emitting a notification of said activated trace session from the at least one subordinate network entity to the network managing entity.
