Title: SYNCHRONOUS DATA PROCESSING METHOD AND DEVICE
Abstract:
Disclosed in the present invention are a synchronous data processing method and device. The method comprises: transmitting signaling and/or forwarding packets to M+N slave TPs; synchronizing downlink data with the slave TPs by sending signaling and/or forwarding packets. Data is synchronized between M slave TPs and a master TP on a packet data convergence protocol (PDCP) layer, and data is synchronized between N slave TPs and the master TP on a PDCP/radio link control (RLC)/media access control (MAC) layers, and M ≥ 0, N ≥ 0, and M + N ≥ 1. The present invention solves the problem in the relevant art of how to control the cost of data synchronization while ensuring cell virtualization, such that the number of layers of data synchronization can be flexibly adjusted and controlled according to the need of cell virtualization, thus controlling the cost of data synchronization while ensuring cell virtualization.
