Method and device for monitoring Iub interface packet-loss rate

A technology of packet loss rate and interface, which is applied in the monitoring field of Iub interface packet loss rate, can solve the problems that the packet loss rate of the downlink and the packet loss rate of the uplink cannot be tested separately, and the QoS situation cannot be fully and truly reflected. The effect of real-time monitoring of QOS quality

Problems solved by technology

[0007] 1. Monitor the QoS of the IP network by periodically sending PING packets (that is, test packets). Since the PING packet is not a normal service packet, it only simulates the actual service packet and cannot fully reflect the actual service in the IP network. QoS situation on the network
[0008] 2. The PING scheme can only test the packet loss on the entire loopback link of RNC->Node B->RNC, and cannot separately test the packet loss rate of RNC->Node B downlink and Node B->RNC uplink Packet loss rate

Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] Embodiments of the present invention provide a method for monitoring the packet loss rate of an Iub interface, and FIG. 2 shows a flow chart of a method for monitoring the packet loss rate of an Iub interface according to an embodiment of the present invention. As shown in Figure 2, it includes the following steps:

[0030] Step S202, identifying the sequence number of the message in the frame of the Iub interface; and

[0031] Step S204, counting the packet loss rate according to the sequence numbers of the received packets.

[0032] The frame can be an uplink DCH or E-DCH frame on the Iub interface, the sending end is Node B, the receiving end is RNC, and the RNC counts the uplink packet loss rate on the uplink according to the received message sequence number.

[0033] The frame can also be a DCH or HS-DSCH frame downlink...

Abstract

This invention provides a method for monitoring lost-packet rate of Iub interface including the following steps: marking message sequence number in the frame of the Iub interface and calculating the packet-lost rate based on the received message sequence number. This invention also provides a monitoring device for packet-lost rate so as to monitor the lost situation of service messages timely.

Description

technical field [0001] The present invention relates to the field of communications, more specifically, to a method and device for monitoring the packet loss rate of an Iub interface. Background technique [0002] With the business development of WCDMA (Wideband CDMA, wideband code division multiple access), especially the gradual development of HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink data access) and HSUPA (High Speed ​​Uplink Packet Access, high-speed downlink data access) Mature, the current ATM (Asynchronous Transfer Mode, asynchronous transfer mode) transmission has been unable to meet the continuous growth of business and bandwidth needs, 3GPP (3rd Generation Partnership Project, third generation wireless cooperation project) agreement suggests that ATM will gradually transition to IP transmission. [0003] Fig. 1 shows a WCDMA network architecture diagram in the related art. In the construction of WCDMA, the most important IP transmission is t...
