System and method for NNI protection uni based on LTE base station backhaul service

A service and base station technology, which is applied in the system field of NNI protection UNI, can solve the problems of long time for canceling a large number of services by the router on the main network side, prolonging the service switching time in the downlink direction, and inconvenient use, so as to shorten the fault response time and reduce the The number of dropped packets, the effect of ease of use

Problems solved by technology

However, when the service transmission volume is large, it takes a long time for the active network side router to cancel a large number of services, prolonging the switching time of services in the downlink direction, which in turn will cause a large number of packet loss phenomena, which is not convenient for people to use.

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0036] see figure 2 As shown, the NNI-protected UNI system based on the LTE base station backhaul service in the embodiment of the present invention includes several user-side routers (A1, A2, A3, A4, A5, A6, A7 and A8), and several network-side routers ( B1, B2, B3 and B4).

[0037] The LTE base station is connected to a user-side router (A2), A2, A1, B1, B2, A4, and A3 are connected end-to-end in sequence to form the first user-side network (A2-A1-B1-B2-A4-A3), A7, A6, A5, B1, B2 and A8 are connected end to end in order to form the second user side network (A7-A6-B5-B1-B2-A8), and B1, B2, B4 and B3 are connected end to end in order to form the network side network (B1 -B2-B4-B3). LTE base station backhaul services need to be transmitted through user-side and network-side networks respectively.

Abstract

The invention discloses a system and method for protecting a UNI based on an NNI of an LTE base station backhaul service, and relates to the field of protection based on an LTE base station backhaul service. The present invention configures BFD on the PW service, and associates the PW service with the BDF through the BFD_ID. When a fault occurs on the user-side network, because BFD is configured on the PW, the BFD of the PW service can quickly notify A2 and B1 of the fault information; The suboptimal host route corresponding to the faulty router is promoted to the preferred host route. The present invention can protect the UNI side link by using the NNI side link to realize fast switching of services, thereby effectively reducing the number of packet loss when the user side link fails, not only improving the stability of network transmission, but also shortening the downlink service time. Reversing the time is convenient for people to use.

Description

technical field [0001] The present invention relates to the field of protection based on LTE base station return service, in particular to a kind of NNI (Network-Network-Interface, network service interface) protection UNI (User-Networks- Interface, user network interface) system and method. Background technique [0002] The LTE is a long-term evolution of the UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) technical standard formulated by the 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project). [0003] At present, the industry's method of processing LTE base station services is generally as follows: establish and upload PW (PseudoWire, pseudowire) services to the network side nodes on the user ring, and the network side nodes transmit PW services through VE (Virtual-Ethernet, virtual Ethernet) interfaces. Bridging to Layer 3 (network layer) VPN (Virtual Private Network, Virtual Private Network) ...
