Description

Method, system and related device for measuring path delay

technical field

Embodiments of the present invention relate to the field of wireless communications, and in particular to a path delay measurement method, system and related devices.

Background technique

The continuous development of the wireless base station technology makes the interaction between the wireless equipment controller (REC, Radio Equipment Controller) and the wireless equipment (RE, Radio Equipment) more and more frequent.

Since the air interface of each RE needs to be aligned in time when sending data, and the path delay from the REC to each RE is different, so in order to ensure normal data transmission, the REC needs to know the path delay between the REC and each RE.

In the prior art, REC and RE are usually directly connected through optical fiber or cable, so the path delay between REC and RE is mainly optical fiber transmission delay or cable transmission delay. In this case, directly test the corresponding physical link The path delay between the REC and each RE can be known by the transmission delay on the path (optical fiber or cable).

With the rise of the baseband processing unit (BBU, Based Band Unit) resource pool, REC and RE have gradually evolved from the original direct connection of optical fiber or cable to interconnection through a transport network, such as a packet transmission network.

( PTN, Packet Transport Network ), or Optical Transport Network ( OTN, Optical Transport Network ), etc.

Due to the complexity of the transport bearer network itself and the variability of network conditions, the path delay between REC and RE no longer depends only on the transmission delay on the physical link, so the path delay measurement method in the prior art It is no longer applicable to the measurement of the path delay between RECs and REs interconnected based on transport bearer networks.
