Problems solved by technology

[0034] That is to say, the instruction of the compressed mode issued by UTRAN is to indicate the transmission gap mode for each measurement purpose separately, and the agreement does not state that it is to design the compressed mode comprehensively considering multiple measurement purposes; and the agreement also explains that the user terminal If multiple transmission gap patterns are found to be the same, it will be considered that such a compressed mode is invalid. Therefore, it can be known that UTRAN designs corresponding transmission gap patterns for each measurement purpose according to the measurement purpose required by the user terminal, so when The multiple transmission gap patterns indicated by UTRAN are designed separately considering each measurement purpose or when the comprehensive consideration of multiple measurement purposes is not enough during the design, it will cause the user terminal to simultaneously use the multiple transmission gap patterns indicated by UTRAN. gap may not be able to meet the measurement performance requirements of the user terminal
For example, it may cause the following problem: when the user terminal uses multiple transmission gap modes, there may be an interval between the end position of the first transmission gap TG and the start position of the second transmission gap TG in two consecutive compressed frames less than 8 time slots, at this time, the measurement performance requirements of the user terminal cannot be met

example 1

[0162] Example 1: If Figure 4 In the first row, the transmission gap mode corresponding to the inter-frequency FDD cell measurement does not meet the measurement performance requirements of the user terminal for the inter-frequency FDD cell measurement, then the user terminal does not perform the measurement for this measurement purpose, and feeds back the transmission gap corresponding to this measurement purpose mode to UTRAN.

example 2

[0163] Example 2: If in Figure 4 On the time axis shown in the fifth row of , if the interval between the end position of the transmission gap marked IF2 and the start position of the transmission gap marked RSSI2 is less than 8 time slots, the measurement of the user terminal cannot simultaneously meet the requirements of inter-frequency FDD cell measurement and GSM RSSI Measurement performance requirements for measurements. If the priority measurement sequence set above is followed, the user terminal will give up the GSM RSSI measurement and feed back the transmission gap mode corresponding to the GSM RSSI measurement to UTRAN, and the user terminal will only perform inter-frequency FDD cell measurement and GSM initial BSIC identification and GSM BSIC Reproven measurements.

example 3

[0164] Example 3: If in Figure 4 On the time axis shown in the fifth row of , if the interval between the end position of the transmission gap marked IF2 and the start position of the transmission gap marked RSSI2 is less than 8 time slots, the measurement of the user terminal cannot simultaneously meet the requirements of inter-frequency FDD cell measurement and GSM RSSI Measurement performance requirements for measurements. If the user terminal follows the order that the larger the corresponding TGPSI value indicated by UTRAN, the lower the priority of its measurement purpose, when the TGPSI measured by the inter-frequency FDD cell is greater than the TGPSI measured by the GSM RSSI, the user terminal will give up performing the inter-frequency measurement. Frequency FDD cell measurement, and feedback the transmission gap mode corresponding to inter-frequency FDD cell measurement to UTRAN, the user terminal only performs GSM RSSI measurement and GSM initial BSIC identificati...

Abstract

The invention discloses a survey method base on different purposes of user terminals. When judging each emission interval module corresponding to different purpose activated by compression mode launched by UTRAN, user terminals perform the purpose of ensuring the measure performance requirement, and feed back the emission interval module not ensuring the performance requirements to UTRAN. Consequently, the invention also proposes a kind of user terminals.

Description

technical field [0001] The present invention relates to a terminal inter-frequency measurement processing technology in a third generation mobile communication system (3G, The 3rd Generation), in particular to a measurement method for a user terminal based on different measurement purposes and a corresponding user terminal. Background technique [0002] Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) is a third-generation mobile communication system that adopts WCDMA air interface technology, and is mainly developed in the WCDMA / GSM global standardization organization 3GPP. [0003] Among them, in the 3GPP UMTS standard, according to whether the radio resource control (RRC, Radio Resource Control) connection is established, the user terminal can be divided into two types: idle (Idle) mode and RRC connected (Connected) mode. The user terminal that establishes an RRC connection in the network (UTRAN, Universal Terrestrial Radio Acc...
