MINIMIZATION OF DRIVE TESTS IN A MOBILE COMMUNICATIONS NETWORK

摘要

A network entity (30) provides area information indicating areas of a mobile communications network, which are at least partially located in a coverage area of the network entity (30) and in which measurements regarding minimization of drive tests are to be performed, and broadcasts the area information (S1). A user equipment (10) receives the area information and determines, based on the area information, that it is in such measurement area, and transmits an information signal which indicates that it is located in the measurement area (S2). In case the user equipment (10) is in an idle mode, the information signal may be transmitted on a specific random access channel during a location update procedure. The specific random access channel may be selected from specific random access channel sequences predefined for the mobile communications network or different between network entities. The network entity (30) may reserve the specific random access channel sequences and indicate them to user equipments via a broadcast control channel and an extended random access channel configuration message (S1a).
