Problems solved by technology

[0015] When the available MDT Log information is saved in the terminal equipment, although the RRC message can be used to notify the network during the establishment process/handover process/reconstruction process/cell update process, and trigger the network to request the terminal device for MDT Log information acquisition, but for replacement After the handover process/reconstruction process/cell update process of the cell, the target cell and the original cell are likely to belong to different RATs (Radio Access Type, radio access type), and in the existing processing process, the terminal device still sends the target cell Send the

Embodiment Construction

[0035] Such as figure 2 Shown is a schematic flowchart of a method for feedback of MDT Log information provided by an embodiment of the present invention. The method specifically includes the following steps:

[0036] Step S201: When the terminal device switches from the idle state to the connected state to connect to the target cell, or switches from the RLF state to the connected state to connect to the target cell, or changes the current home cell to the target cell in the connected state, the terminal device confirms whether It is allowed to feed back the MDT Log information corresponding to multiple wireless access types to the base station of the target cell. The details are as follows:

[0037] Case 1: When a terminal device receives a message carrying configuration information that allows the terminal device to feedback the MDT Log corresponding to any wireless access type, or the terminal device is set to allow feedback of the MDT corresponding to any wireless access type ...

Abstract

The embodiment of the invention discloses a feedback method and device of minimization drive test (MDT) Log information. By using the technical scheme proposed by the embodiment of the invention, terminal equipment can reasonably select whether available Log indication information is sent to a network in accordance with a radio access type (RAT) corresponding to MDT Log information stored in the terminal equipment, thus avoiding a phenomenon that effective MDT Log information is lost resulting from feedback of the MDT Log information when an existing RAT does not correspond; and in addition, the terminal equipment determines whether the available Log indication information is reported to a network side in accordance with an actual RAT condition, so that report of unnecessary MDT Log information can be avoided, and air interface resources of a system can be effectively saved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for feedback of MDT Log information. Background technique [0002] In the existing technical solutions, MDT (Minimization Drive Test) measurement is divided into two types: Immediate MDT (Immediate Minimization Drive Test) and Logged MDT (Logged Minimization Drive Test): [0003] Immediate MDT, the MDT measurement and report performed by the terminal equipment in the connected state, and reuse the form of RRM (Radio Resource Management, radio resource management) measurement. Once the reporting conditions are met, the terminal equipment immediately reports to the eNB (evolved Node B, evolved base station). ) / RNC (Radio Network Controller) reports the measurement results. [0004] Logged MDT, the MDT measurement performed by the terminal device in the idle state, and report it in the subsequent connected state. Once the configured trigger condition i...
