Abstract
The present invention relates to a method and a network control node for tracing activity and monitoring performance of user equipments in a partly IP-based wireless communications network. The wireless communications network comprises operator controllable and/or operator uncontrollable wireless access points in communication with a network control node via one or more operator controllable and/or operator uncontrollable Internet Protocol, IP, networks. The described method is characterized by a first step of receiving a trace triggering request and user equipment identification, at a network control node, from a first network node. Alternatively, the trace triggering request is received on a signaling connection that explicitly identifies the user equipment. The network control node then starts a trace recording and information retrieval procedure relating to the identified user equipment and identifies all used IP networks and user equipment serving access point. The method further comprises the steps of analyzing the IP networks used between the network node and the user equipment and/or analyzing the user equipment serving access point. Thereafter, a trace printout is created including analyzing results and retrieved information, the printout is to be sent to a second network node, or stored locally for later retrieval.

15. A method for controlling user equipment activity in a wireless communications network, the wireless communications network having operator controllable access points and operator uncontrollable access points that are in communication with a network control node via one or more operator controllable and/or operator uncontrollable Internet Protocol (IP) networks, the method comprising the steps of:
-
receiving a trace triggering request and user equipment identification at the network control node from a first network node; starting, at the network control node, a trace recording and information retrieval procedure relating to the identified user equipment; identifying, at the network control node, all used IP networks and the access point serving the user equipment; analyzing the IP networks used between the network control node and the user equipment and/or analyzing the access point serving the user equipment; and including analyzing results in a trace printout together with retrieved information to be sent to a second network node. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
