摘要
Systems, methods, and computer-readable media for improving accuracy for providing precision time protocol (PTP) frequency and phase synchronization to each unanchored small cell site in a cluster over non on-path supported networks are provided. In embodiments, the method includes continuously measuring one-way delay down (OWDd) and delay offset down from a host site to an anchored site and one-way delay up (OWDu) and delay offset up from the anchored site to the host site. Round trip (RT) delay from the host site to each unanchored site is continuously measured. A one-way delay down prime (OWDd′) is determined for each unanchored site by applying the ratio of OWDu/OWDd to the corresponding RT delay for each unanchored small cell site. An adjusted dynamic corrective offset (DCO) is determined for each unanchored site by adding the respective OWDd′ to the respective time stamp and the delay offset down.
