Method and system for radio service optimization using active probing over transport networks

摘要

A method and system for determining quality and capacity of a transport monitoring connection between radio service nodes to facilitate local management of subscriber connections are disclosed. One method includes sending first test packets from a first radio service node to a second radio service node via the transport monitoring connection. Second test packets are received from the second radio service node. The second test packets have information added to the first test packets by the second radio service node. The second test packets are analyzed to determine a quality and a bandwidth of the transport monitoring connection. Control and user plane functions are informed when transport monitoring performance is one of degraded and improved based on the quality and bandwidth. The method includes making radio service provisioning decisions based on the quality and bandwidth of the transport monitoring connection.

1. A method of monitoring performance of a transport monitoring connection connecting a first radio service node and a second radio service node, the method comprising:
sending outgoing packets to the second radio service node via the transport monitoring connection, the outgoing packets including forward sequence numbers; receiving incoming packets from the second radio service node via the transport monitoring connection, each incoming packet received in response to the transmission of at least one outgoing packet, the incoming packets including reverse sequence numbers, the reverse sequence numbers being a different sequence from the forward sequence numbers; processing the incoming packets to determine performance metrics for the transport monitoring connection, the processing including processing the forward and reverse sequence numbers to determine a packet loss ratio in a forward direction and a reverse direction; verifying, via a control plane entity, a state of the transport monitoring connection based on the performance metrics before one of admitting a subscriber connection and activating a radio feature is performed by the first radio service node; and informing, via a user plane entity, a radio link scheduler of a state of the transport monitoring connection based on the performance metrics before a scheduling of at least one bearer packet to at least one subscriber is performed by the radio link scheduler.
