1. A method of handling minimization of drive tests (MDT) measurement for a mobile device in a wireless communication system, the method comprising:
- registering to a first public land mobile network of the wireless communication system, wherein the mobile device is configured with an MDT measurement configuration received from the first public land mobile network; and
performing the following steps;
continuing performing measurement logging in a second public land mobile network according to the MDT measurement configuration when the mobile device registers to the second public land mobile network belonging to the same operator as the first public land mobile network; and
continuing performing measurement logging in the first public land mobile network according to the MDT measurement configuration when the mobile device is in coverage of the first public land mobile network but rejected by the first public land mobile network, wherein the mobile device is rejected by receiving a message with a reject cause of that a location area or tracking area is not allowed for the mobile device, no suitable cell is in the location area or tracking area, or a closed subscriber group of the first public land mobile network is not authorized to the mobile device.

Abstract
A method of handling minimization of drive tests, hereafter called MDT, measurement for a mobile device in a wireless communication system is disclosed. The method includes registering to a first public land mobile network, and maintaining MDT measurement configuration when the UE registers to a second public land mobile network belonging to an operator as the first public land mobile network is, or the UE is in coverage of the first public land mobile network but registering to no public land mobile network.

2. A method of handling minimization of drive tests (MDT) measurement for a mobile device in a wireless communication system, the method comprising:
-
registering to a public land mobile network of the wireless communication system; invalidating a MDT measurement configuration when the mobile device is rejected by the registered public land mobile network (PLMN) with a reject cause in a non-access stratum (NAS) message sent by the PLMN, comprising; invalidating the MDT measurement configuration when the mobile device is rejected by the registered public land mobile network with the reject cause, wherein the reject cause is that an international mobile subscriber identity (IMSI) of the mobile device is unknown in a home location register of the wireless communication system, the mobile device is illegal, or the public land mobile network is not allowed; and stopping measurement logging corresponding to the MDT measurement configuration.

3. A mobile device of a wireless communication system for handling minimization of drive tests (MDT) measurement, the mobile device comprising:
-
a processing means, for executing a program; and a storage unit, coupled to the processing means, for storing the program which instructs the processing means to perform the following steps; registering to a public land mobile network of the wireless communication system; invalidating a MDT measurement configuration when the mobile device is rejected by the registered public land mobile network (PLMN) with a reject cause in a non-access stratum (NAS) message sent by the PLMN, comprising; invalidating the MDT measurement configuration when the mobile device is rejected by the registered public land mobile network with the reject cause, wherein the reject cause is that an international mobile subscriber identity (IMSI) of the mobile device is unknown in a home location register of the wireless communication system, the mobile device is illegal, or the public land mobile network is not allowed; and stopping logging corresponding to the MDT measurement configuration.
