Embodiment Construction

[0023] As mentioned in the background, the existing handover technology does not take into account the influence of the network quality and rate on the handover when the mobile terminal is handed over. In this way, when the mobile terminal executes the HSDPA high-speed service, when the network side issues a different system measurement command, the terminal does not support the GSM BSIC verification well, especially when there are GSM neighbors with the same frequency, the terminal measurement error is serious, and it is easy to As a result, PS switching fails and disconnection occurs, which seriously affects user perception.

[0024] Although the handover of existing mobile terminals for high-speed services often fails, the inventors have found that these terminals will perform BSIC checks on GSM signals in the low-speed DCH (Dedicated Channel, dedicated channel) state, effectively avoiding the inaccuracy of the target handover cell As a result, switching between PS systems ...

Abstract

The invention discloses a switching method. The method comprises the steps that when it is judged that a mobile user needing to conduct switching has service borne by an HSDPA channel currently, the mobile user is transferred to a DCH channel at the rate lower than an intersystem switching rate threshold; 3C measurement control is issued to the mobile user when the mobile user is located in the DCH channel and the current network rate is not higher than the intersystem switching rate threshold so that UE can free up adequate downlink resources to conduct BSIC verification, intersystem measurement can be accurately initiated, the PS intersystem switching success rate and the network dropping rate can be increased, and the perceptibility of the user is promoted.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a switching method. The present invention also relates to a radio network controller RNC. Background technique [0002] With the continuous development of living standards, people pay more and more attention to the experience of using mobile terminals. As a 3G (third-generation mobile communication standard) standard that enables users to access high-speed networks, mobile terminals in TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) networks operate in HSDPA ( The handover quality between the High Speed ​​Downlink Packet Access (HSD) network and the GSM (Global System for Mobile Communication, Global System for Mobile Communication) network has become an important factor to measure user experience. [0003] Such as figure 1 As shown in FIG. 2 , it is a schematic flow chart of handover of a mobile terminal under a TD-SCDMA network in the prior a...
