Patent ID: 7630335

Claim:
A method of measuring and analyzing packet-switched traffic in a Universal Mobile Telecommunications System, UMTS, network having a mobile station linked to a base station through a radio channel, the base station being linked to a radio access network, and the radio access network being linked to a support node in a packet core network, wherein cell-level location information of the mobile station is obtained in a node in the radio access network, said method comprising: adding the obtained cell-level location information to user-plane packet headers when the radio access network detects that the mobile station is performing a handover; transmitting the user-plane packets carrying the cell-level location information towards the packet core network; measuring the cell-level location information, user data traffic, and packet data protocol, PDP, context information at the packet core network level; and determining end-to-end quality-of-service, QoS, metrics for the mobile station by analyzing the cell-level location information, user data traffic, and PDP context information measured at the packet core network level.
