Embodiment Construction

[0064] Figure 2 is a flow chart of switching in between CS domain systems, including the following signaling process:

[0065] 1. When the GSM BSS decides to perform inter-system handover based on the measurement, the BSC sends a handover request (Handover Required) message to the GSM MSC, requesting the other system to prepare for the inter-system handover;

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

[0067] 3. WCDMA CN sends a relocation request (Relocation Request) to RNC;

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

[0069] 5. The 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 message;

[0071] 7. Through the existing wireless connection, the BSC sends an Inter-System to U...

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 faults between systems. Background technique [0002] The WCDMA system is an open system, which mainly includes CN (Core Network, 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 interface with other RNCs. interface, and the UU interface between UE and RNC, as shown in Figure 1. [0003] The inter-system handover means that the UE switches from the 2G system (GSM) to the 3G (WCDMA) system, and the service is not interrupted. In the initial stage of network construction, operators will only deploy 3G systems in some hotspot areas to control the scale of investment, and other areas ...
