METHOD AND APPARATUS FOR MONITORING CONNECTIVITY IN A LONG TERM EVOLUTION NETWORK |
摘要 |
A method and apparatus for monitoring connectivity in a network at a bearer path layer are disclosed. For example, the method receives a request to monitor a user endpoint, identifies an internet protocol address of the user endpoint, an internet protocol address of each transport network element between the user endpoint and a bearer trace server, a bearer path identification of each bearer used by the user endpoint, a quality of service associated with each bearer used by the user endpoint, and a tunnel identification of each bearer used by the user endpoint; and performs a fault isolation and performance monitoring at a bearer path layer, wherein the fault isolation identifies a particular segment where a fault is detected at the bearer path layer. |

1. A method for monitoring a connectivity in a network, the method comprising:
receiving, by a processor, a request to monitor a user endpoint; identifying, by the processor, an internet protocol address of the user endpoint, an internet protocol address of each transport network element between the user endpoint and a bearer trace server, a bearer path identification of each bearer used by the user endpoint, a quality of service associated with each bearer used by the user endpoint, and a tunnel identification of each bearer used by the user endpoint; waking up, by the processor, the user endpoint via an instruction sent to the bearer trace server located in a core network for a packet to be sent from the bearer trace server remotely located in the core network from the user endpoint in the network to reestablish a bearer; performing, by the processor, a performance measurement, wherein the performing the performance measurement comprises measuring a round-trip time of a packet associated with a particular segment; and performing, by the processor, a fault isolation at a bearer path layer after the user endpoint is woken up, wherein the fault isolation identifies the particular segment where a fault is detected at the bearer path layer. |
