Problems solved by technology

[0005] For a UE working under the HSDPA frequency point, it is impossible to find more than three consecutive free time slots for measurement on this frequency point. In this way, the UE under the TD-SCDMA system cannot switch to the GSM system. take measurements

Embodiment Construction

[0065] The measurement of the GSM system is divided into GSM carrier frequency RSSI (Received Signal Strength Indicator) measurement that requires BSIC (Base transceiver Station Identity Code, base station identification code) verification process and GSM carrier frequency RSSI measurement that does not require BSIC verification process . When there are multiple cells with the same frequency but different BSICs in the adjacent GSM cells adjacent to the TD serving cell, it is necessary to start the BSIC verification process to distinguish the measurement results of different GSM cells, so as to prevent the network side from being unable to distinguish different When the measurement result of the GSM cell is low, the handover purpose is unclear and the handover fails. RSSI measurement for BSIC verification is divided into two processes (see TS 25.123 protocol description for specific process): initial BSIC identification and BSIC reconfirmation process. In order to achieve meas...

Abstract

The invention discloses an intersystem measuring method, an intersystem measuring device and an intersystem measuring system, which relate to the field of mobile communication and solve the problem that user equipment (UE) cannot be switched to a global system for mobile communication (GSM) for measuring in a time division-synchronization code division multiple access (TD-SCDMA) system. The method comprises the following steps of: receiving transmission interval configuration control signaling transmitted by a radio network controller (RNC); determining the position of a transmission interval according to the transmission interval control signaling; switching to a target system frequency at the transmission interval so as to measure system performance; and reporting a measurement report to the RNC according to a measurement result. The technical scheme provided by the invention is suitable for the TD-SCDMA system.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to an inter-system measurement method, device and system. Background technique [0002] The TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access technology) system is mainly used to carry PS (Packet Switch, packet switching) services. HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access technology) frequency points are mainly used to carry high-speed PS services. When the UE (User Equipment) in the TD-SCDMA system moves or the wireless signal quality changes, the UE can select the cell with the best signal quality between the systems through inter-system measurement, and switch the service to GSM (Global System for Mobilecommunication, Global Mobile Communication) system. Since the operating frequency of the GSM system is different from that of the TD-SCDMA system, the UE need...
