Radio link failure report filtering

摘要

Embodiments of the invention include a method for collecting RLF data in a wireless network. The method may include receiving, by a first radio access node, RLF data related to a connection failure experienced by a UE. The method may then include determining whether the RLF data satisfies at least one condition and, when it is determined that the RLF data satisfies the at least one condition, sending the RLF data to at least one of a second radio access node and an RLF data collection entity. In one embodiment, the RLF data may be received from a second radio access node or the UE.

1. A method for collecting radio link failure data in a wireless network, the method comprising:
receiving, by a first radio access node, radio link failure data related to a connection failure experienced by a user equipment on a radio link between the user equipment and a radio access node; determining, using information contained in the radio link failure data, whether the radio link failure data satisfies at least one filtering condition wherein the at least one filtering condition comprises at least one of: a presence of detailed location information in the radio link failure report, a protocol release version of the radio link failure report, a signal strength of non-serving cells above/below a threshold, a carrier frequency of a last serving cell, PLMN or TAI of the last serving cell, a specific attribute of the radio link failure report is above/below a threshold, and when it is determined that the radio link failure data satisfies the at least one filtering condition, sending the radio link failure data to at least one of a second radio access node and a radio link failure data collection entity.
