Problems solved by technology

[0004] The purpose of the present invention is to provide a statistical method for layer 2 statistics, CU and DU, to solve the situation that CU and DU are separated, because the protocol layers included in layer 2 are distributed in different units, resulting in the inability to analyze layer 2 The problem of statistics

Embodiment Construction

[0214] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0215] In the next generation mobile communication system (such as 5G), the access network supports the same centralized architecture as the traditional LTE system, such as figure 1 as shown, also supports the figure 2 The architecture where the CU is separated from the DU is shown. Such as figure 1 As shown, under the centralized architecture, SDAP (Service Data Adaptation Protocol, business data adaptation protocol), PDCP (Packet Data Convergence Protocol, packet data convergence protocol), RLC (Radio Link Control, radio link layer control protocol), MAC (Media Access Control media access control layer) and PHY (physical layer, physical layer) are concentrated in one access network entity. In a distributed architecture, SDAP, PDCP, RLC, MAC, and PH...

Abstract

The invention provides a statistical method of layer-2 statistical magnitude, a central unit (CU) and a distributed unit (DU). The method comprises the steps of using the CU to record first time at which each data packet arrives at a default protocol layer in a layer-2 at the side of the CU; enabling the CU to perform a first target event based on the first time of each data packet, wherein the first target event comprises: sending the first time of each packet to the DU; or calculating the layer-2 statistical magnitude based on the first time of each data packet; or calculating average delay of data packets at the side of the CU, and sending the average delay of the data packets at the side of the CU to the DU or operation, administration and maintenance (OAM), or calculating average delay of data packets of the layer-2 according to the average delay of the data packets at the side of the CU. Therefore, the method can realize the statistics for the layer-2 statistical magnitude under the condition that the CU is separated from the DU.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a statistical method for layer 2 statistics, CU (Central Unit, central unit) and DU (Distributed Unit, distributed unit). Background technique [0002] In a traditional LTE (Long Term Evolution, long-term evolution) system, the access network entity supports a centralized architecture, that is, different protocol layers are concentrated in the same access network entity. In the next generation mobile communication system, the access network entity not only supports the same centralized architecture as in the traditional LTE system, but also supports the architecture where CU and DU are separated, that is, different protocol layers can be distributed in different units. [0003] For the case where the CU is separated from the DU, since the protocol layers included in the layer 2 are distributed in different units, it is impossible to collect statistics on the la...
