Embodiment Construction

[0064] figure 2 Enter the flowchart for switching between circuit domain systems, including the following signaling procedures:

[0065] 1. When the GSM BSS decides to switch between systems on the basis of measurement, the BSC sends a Handover Required (Handover Required) message to the GSM MSC, requesting the other party's system to prepare for the handover between systems;

[0066] 2. GSM MSC forwards this request to WCDMA CN (Send PrepareHandover via MAP / E message);

[0067] 3. WCDMA CN sends a Relocation Request to RNC;

[0068] 4. After WCDMA UTRAN prepares resources for inter-system handover, RNC responds with a relocation request confirmation message (Relocation Request Ack) to WCDMA CN;

[0069] 5. WCDMA CN sends a MAP / E message to prepare a handover response (Prepare HandoverResponse) to the GSM MSC;

[0070] 6. The GSM MSC responds to the initial request of the BSC by sending a Handover Command (Handover Command) message;

[0071] 7. Through the existing wireless conn...

Abstract

Being applicable to switching from 2G system to 3G system the method establishes parameter information set of switching fault between systems, and sets up reporting parameter items of switching fault between systems in the information set. When carrying out switching between systems, the method executes following steps: (1) monitoring switching procedure between systems, and receiving fault information sent by system when switching is in failure; (2) based on fault cause pointed out by fault signal to query parameter item required to report in information set of switching fault; (3) based on the said parameter item to obtain corresponding parameter value from system, and to write the value to message of reporting fault; (4) sending the message of reporting fault to network management center. The invention can obtain specific cause so as to guide optimization of network.

Description

Technical field [0001] The invention relates to switching from a 2G system to a 3G system, in particular to a method for reporting switching failures between systems. Background technique [0002] The WCDMA system is an open system, which mainly includes CN (Core Network), UTRAN (UMTS Terrestrial Radio Access Network) and UE (User Terminal). The RNC (Radio Network Controller) belongs to the UTRAN part. There are standard interfaces between RNC and other network elements, such as the IU interface with CN, the IUB interface with NodeB (base station), and the IUR with other RNCs. Interface, and UU interface between UE and RNC, such as figure 1 Shown. [0003] Inter-system handover means that the UE switches from the 2G system (GSM) to the 3G (WCDMA) system, and the service is not interrupted. Since in the initial stage of network construction, operators will only deploy 3G systems in some hotspots to control the scale of investment, and other areas are covered by 2G systems. In thi...
