The present invention provides a PTN networking architecture and a service bearing method based on the PTN networking architecture. The networking architecture includes: multiple subsystems connected through a dispatching ring, and the dispatching ring is used to dispatch cross-subsystem inter-base station interconnection services and base stations Multi-homing service; the subsystem includes: an access ring and a convergence ring connected to the access ring; the access ring is connected to a wireless base station for receiving network signals of the wireless base station and transmitting the network signals To the convergence ring, the network signal carries at least one of the inter-base station interconnection service and the base station multi-homing service; the convergence ring is used to process the network signal to realize the inter-base station interconnection service and the base station multi-homing service separation and transfer. The technical solution of the present invention provides a large-capacity PTN networking architecture and a service bearing method, and solves the problem of eNodeB service transmission in the TD‑LTE period.
Description
technical field [0001] The present invention relates to the field of transport network technology, in particular to a PTN networking architecture and a service bearing method based on the PTN networking architecture. Background technique [0002] TD-LTE (TD-LTE, Time Division Long Term Evolution, Time Division Long Term Evolution), as one of the mainstream technologies of IMT-Advance, will enable mobile networks to truly enter the era of mobile broadband. Compared with the existing 2G and 3G mobile communication systems, TD-LTE puts forward higher requirements for the backhaul network in terms of high bandwidth, low delay, horizontal forwarding, and time-synchronized ground transmission. [0003] First, bandwidth requirements have grown from a few megabytes or tens of megabytes in the 2G / 3G era to hundreds of megabytes in the LTE era. [0004] Second, LTE needs to provide flexible QoS and stricter end-to-end delay. According to 3GPP regulations, the end-to-end one-way delay...
