Title:
DUPLICATION OF TRAFFIC OF A RADIO BEARER OVER MULTIPLE PATHS
Document Type and Number:
WIPO Patent Application WO/2019/245447
Kind Code:
A8
Abstract:
Radio network equipment (1700) is configured to implement a radio access network, RAN, central unit (12-C). The radio network equipment (1700) is configured to decide, by the RAN central unit (12-C), which of multiple RAN distributed units (12-D1, 12-D2) is to be responsible for activating duplication of traffic of a radio bearer (16) over multiple paths (16-1, 16-2). Different ones of the RAN distributed units (12-D1, 12-D2)serve different respective ones of the multiple paths (16-1, 16-2). The radio network equipment (1700) is also configured to transmit, from the RAN central unit (12-C), control signalling (20) to each of one or more of the RAN distributed units (12-D1, 12-D2) indicating whether or not the RAN distributed unit is responsible for activating duplication of the traffic of the radio bearer (16) over the multiple paths (16-1, 16-2).
