Embodiment Construction

[0055] The invention proposes a method and a system for obtaining RRC messages on the TD-SCDMA Iub interface and forming a signaling flow. The present invention can use the RRC, NodeB Application Part (NodeB Application Part, NBAP) and access layer link control application (Access Link Control Application Part, ALCAP) message of the user equipment (UE) in the UTRAN on the Iub interface in the connection mode Associated to form a complete signaling process. Fig. 3 is a schematic diagram of the signaling flow on the Iub interface at the call initiation stage, from which it can be seen that the timing and order of each message of the RRC, NBAP and ALCAP protocols are interacted, and the transmission used to transmit each RRC message can also be seen Channel type and RLC entity mode.

[0056] As shown in Figure 5, the method of the present invention comprises the following steps:

[0057] Step 501: Configure the VPI / VCI parameters of the AAL5 link of the wireless network control...

Abstract

The invention relates to an Iub interface signaling process synthesis method, which includes that: the first step is to configure the parameter VPI / VCI of the AAL5 link path which is corresponding to the wireless network control plane NBAP of a monitored Iub interface and transmission network control plane ALCAP signaling, the relationship between the path mark of a user plane AAL2 link path and VPI / VCI, and to configure the parameter VPI / VCI / CID of the transmission format set of a public transmission channel in a monitored small area and the AAL2 link path of the public transmission channel. The second step is to read an AAL service data unit which is acquired from the Iub interface, obtain wireless resource control messages, NBAP protocol messages or ALCAP protocol messages from the AAL service data unit and implement associated processing on wireless resource control messages, NBAP protocol messages and / or ALCAP protocol messages for synthesizing the Iub interface signaling process. The invention can help a third party which does not depend on firms to monitor the Iub interface signaling.

Description

technical field [0001] The invention relates to the monitoring and maintenance of a mobile communication network, in particular to a method and a system for synthesizing an Iub interface signaling flow. Background technique [0002] The TD-SCDMA network can be divided into two parts functionally: UMTS Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network, UTRAN) and core network (Core Network, CN). Among them, because the physical layer technology adopted is completely different from GSM (Global System for Mobile Communication) system, the protocol structure of UTRAN has changed greatly compared with the access network of GSM. In the early stage of network deployment and operation, UTRAN is a relatively prone to failure and a key part of network performance optimization. Use signaling monitoring tools to collect, organize, analyze and correlate UTRAN signaling, present the complete signaling activity process of UE in UTRAN, form call detail records (Call D...
