METHOD AND APPARATUS FOR MANAGING ACCESS TO USER EQUIPMENT EVENT INFORMATION

摘要

A method of managing access to problem event information collected by a User Equipment (UE). In one novel aspect, access to the problem event information is determined by a public land mobile network (PLMN) list stored in the UE. The UE collects problem event information, stores a PLMN list, and sends an indication that problem event information is available to a Radio Access Network (RAN) controller. In response, the RAN controller sends a request indicator to the UE requesting the event information. The UE transmits the requested event information when the requesting PLMN is included in the PLMN list stored in the UE. In one embodiment, the event information includes Minimization Drive Test (MDT) measurement information. In another embodiment, the event information includes radio link failure information. The solution enables managing access to problem event information with maximum simplicity and minimum impact to existing systems.
