Embodiment Construction

[0028] (1) MDT measurement

[0029] The measurement quantities of the UE determined by the MDT measurement include but are not limited to:

[0030] 1. Periodical downlink pilot measurements (periodic downlink pilot measurements)

[0031] 2. Serving Cell becomes worse than threshold (the service cell becomes worse than the set threshold)

[0032] 3. Transmit power headroom becomes less than threshold (PHR becomes worse than the set threshold)

[0033] 4. Random access failure (random access failure)

[0034] 5. Paging Channel Failure (paging channel failure to receive)

[0035] 6. Broadcast Channel failure (broadcast channel failure to receive)

[0036] 7. Radio link failure report (radio link failure report)

[0037] It should be noted that, in addition to the above seven measurement quantities, it is not ruled out to add other measurement quantities in the subsequent standard process, for example, measurement quantities related to QOS (Quality of Service) of the UE. Embo...

Abstract

The invention discloses a minimization drive test (MDT) processing method based on a coverage hole and equipment. The method comprises the following steps: when user equipment (UE) detects that the UE enters into a coverage hole, if a first log MDT timer is not exceeded, the UE stops the first log MDT timer, and determines whether the UE is the first time to enter into the coverage hole after configuring log MDT measurement; if so, the UE starts a second log MDT timer which is used for recording existence time of the UE in the coverage hole. In the invention, in a coverage hole scene, it is ensured that the UE can record a measurement result and a geographical position of entering into and leaving the hole to enable a service provider to obtain a coverage map and to optimize network coverage.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for processing MDT based on coverage holes. Background technique [0002] In the future mobile communication system, it is hoped that by introducing a network self-optimization mechanism, manual participation in network planning and operation and maintenance will be reduced, and the network will automatically optimize parameters according to statistics, thereby reducing network construction and operation costs. In order to reduce network operation and maintenance costs, it is hoped that the network configuration UE (User Equipment, User Equipment) reporting method can be adopted to reduce the work of manual drive tests, and it is hoped that wireless measurement information in areas that cannot be reached by ordinary drive tests can be obtained. [0003] Based on the above purpose, LTE (Long Term Evolution, long-term evolution) has been determi...
