Measurement method of UE (user equipment) in CELL_DCH (dedicated channel) state

Abstract

The invention discloses a measurement method of UE (user equipment) in a CELL_DCH (dedicated channel) state, which comprises the following steps: for any measurement operation, the UE in the CELL_DCH state in a TD-SCDMA (time division-synchronous code division multiple access) system determines a wireless frame number (SFN) executing the operation, and SFN mod(2^k)=Offset+i, wherein i=0,1,...,M_Length-1, k is a preset calculation coefficient of the measurement period, Offset is a preset offset of the measurement time, and M_Length is a preset time length which is required for measurement and takes a wireless frame as a unit; the designated operation type includes pilot frequency measurement, inter-system measurement and GSM (global system for mobile communication) BSIC (base station identity code) acknowledgement / repeated acknowledgement; and on the determined wireless frame, the network side does not schedule the UE or send data or other control instructions to the UE, and the UE executes corresponding measurement operation. By adopting the method disclosed by the invention, the UE in the CELL_DCH state can perform pilot frequency or inter-system measurement as well as GSM BSIC acknowledgement / repeated acknowledgement at proper time.

Description

technical field [0001] The present invention relates to the technology in the TD-SCDMA system, in particular to a UE measurement method in CELL_DCH state, specifically including inter-frequency measurement, inter-system measurement, GSM BSIC confirmation and GSM BSIC re-confirmation. Background technique [0002] UE working in the TD-SCDMA system needs to perform various measurement operations periodically, including inter-frequency and inter-system measurement and GSM BSIC confirmation / reconfirmation, in order to ensure the normal progress of cell handover or system handover. [0003] The inter-frequency measurement refers to the measurement of main frequency points of inter-frequency cells, and the inter-system measurement refers to the measurement of operating frequency points of other systems. [0004] Specifically, in the measurement of different systems, the measurement of GSM includes three processes: (1) RSSI measurement of the GSM carrier, (2) GSM BSIC confirmation,...

AI Technical Summary

Problems solved by technology

[0012] However, for a UE in the CELL_DCH state, there is no specific implementation plan for determining the operation time when performing inter-frequency and inter-system measurements on the UE

[0013] For GSM BSIC confirmation, the UE usually performs corresponding operations in its own idle time slot; since the UE idle time slot is restricted by the UE scheduling on the network side, the time slot used for GSM BSIC confirmation / re-confirmation is often not Definitely, and usually several consecutive times are required for BSIC confirmation / reconfirmation, for example, multiple consecutive subframes or radio frames are required, and the UE may not be able to complete BSIC confirmation / reconfirmation within a certain period of time due to the lack of free time slots or confirm / revalidate failed
