Problems solved by technology

And this update process is usually longer, generally all in 7-8 seconds, at this time if the wireless environment where the terminal is located changes, the terminal will initiate a cross-MSC handover request, but since the handover request is initiated during the location area update process, There will inevitably be a cross-MSC handover failure. This handover failure does not mean that there is a problem with the network service quality. Optimization will also be difficult to completely avoid this switching failure due to the long update time of the location area

Embodiment 1

[0051] Such as figure 1 As shown, it is a schematic flow chart of Embodiment 1 of the method for obtaining inter-mobile switching center handover performance index information of the present invention. In this embodiment, the step of obtaining handover performance index information includes:

[0052] Step 101, respectively obtain the total number of times that RNC-A is switched to RNC-B and RNC-B is switched to RNC-A, and respectively obtain the number of times that RNC-A is switched to RNC-B and RNC-B is switched to RNC-A. the total number of successes;

[0053] Step 102, according to the obtained total number of handovers and the total number of successful handovers, obtain the handover success rate and / or handover failure rate of the inter-MSC handover by calculation.

[0054] The operation of calculating and obtaining the handover success rate and / or handover failure rate of cross-MSC handover is specifically:

[0055] In this embodiment, the handover success rate and / o...

Embodiment 2

[0062] Such as figure 2 As shown, it is a schematic flowchart of Embodiment 2 of the method for obtaining inter-mobile switching center handover performance index information of the present invention. Compared with the previous embodiment, before the step 101 of obtaining the total times of cut-outs and the total times of successful cut-outs, this embodiment also includes setting signaling collection for accumulating the total times of cut-outs and the total number of successful cut-outs The step 100 of the point specifically includes:

[0063] RNC-A is set to switch to the signaling collection point of the total number of times of switching out of RNC-B to be the Iu interface relocation request (Iu Relocation Required) signaling that RNC-A sends, and the cause value of this signaling message is the cross-location area cell relocation Optional, the reason value in this article is used to describe the type of reason for initiating an operation. ;

[0064] The signaling coll...

Embodiment 3

[0069] Such as image 3 As shown, it is a schematic flowchart of Embodiment 3 of the method for obtaining inter-MSC handover performance index information of the present invention. Compared with the previous embodiment, this embodiment also includes the operation of carrying the location area update signaling in the coverage area of ​​the inter-MSC handover on the FACH:

[0070] Step 100a, on the first RNC and the second RNC, turn on the function switch of the FACH bearing location area update signaling, so that when the terminal in the cross-MSC handover coverage area initiates the location area update, all the air interface signaling of the terminal is on the FACH and keep the terminal in the CELL-FACH state.

[0071] Considering that the 3GPP protocol stipulates that the RRC link can be carried on the FACH channel or the DCH channel, and the RRC link established due to the update of the location area only needs data transmission on the signaling plane. If the DCH channel i...

Abstract

The invention relates to a method for acquiring performance index information by switching a spanning mobile switching center, which comprises: respectively obtaining total switching-out number and total switching-out success number for switching to a second wireless network controller from a first wireless network controller and switching to the first network controller from the second wireless network controller; and calculating to obtain switching success rate and/or switching failure rate for switching by the spanning mobile switching center according to the total switching-out number and the total switching-out success number. The invention also relates to a system for acquiring performance index information by switching the spanning mobile switching center. The method and the system are applicable to bidirectional switching and unidirectional switching, are provided with an RNC to send a Iu interface transfer request signaling and a Iu interface release completion signaling which are respectively taken as signaling acquisition points for the total switching-out number and the total switching-out success number, and avoid counting loss caused by signaling loss. The method and the system also avoid spanning MSC switching accidents during updating, and ensure consistency of performance index and real service quality.

Description

technical field [0001] The present invention relates to the field of third-generation mobile communication, in particular to a method and system for obtaining performance index information for handover across mobile switching centers (Mobile Switching Center, MSC for short) in third-generation network operation. Background technique [0002] In a common mobile network, many MSCs are generally set up to manage location areas of mobile terminals in different service areas. However, with the frequent social interaction, the mobility of people holding mobile terminals is gradually increasing, and there are more and more cross-MSC handovers. This requires network operators to provide high-quality cross-MSC handover performance to ensure that users quality of service. [0003] Inter-MSC handover performance is usually reflected in some performance indicators, such as handover success rate and handover failure rate, etc. The network management system can count these cross-MSC perf...
