Abstract
The invention relates to the field of communication, and discloses a cell measurement method and a system thereof. The method comprises that: adding timed idle frames to a network side, and ensuring no valid data is transmitted on the added idle frames; and performing measurement on inter-system and different-frequency cells by utilizing time slots in the idle frames by using a terminal. As the terminal can utilize all the time slots in the idle frames to perform measurement on the inter-system and different-frequency cells, the method and the system effectively avoid the condition of no enough idle frames to finish the measurement of the inter-system and different-frequency cells when a current service has relatively more configuration time slots to further find the best inter-system and different-frequency cells out under a currently connected network.
Description
Technical field
The present invention relates to the communications field, particularly the different system in the communications field, alien-frequency district measuring technique.
Background technology
Along with the development of the communication technology, various types of wireless communication systems are there are, as global system for mobile communications (Global System for Mobile communication, be called for short " GSM "), Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, be called for short " WCDMA "), TD SDMA (Time Division Synchronous Code Division MultipleAccess, be called for short " TD-SCDMA "), micro-wave access to global intercommunication (WorldwideInteroperability for Microwave Access, be called for short " WiMAX "), Long Term Evolution (LongTerm Evolution, be called for short " LTE "), bluetooth, China Mobile multimedia broadcasting (China MobileMultimedia Broadcasting, be called for short " CMMB ") etc.
Many terminals (as mobile phone) all can be supported two kinds of wireless systems (or wireless standard), as not only supported GSM but also support TD-SCDMA.The terminal of two kinds of wireless systems of this support is commonly referred to dual-mode terminal.Support about mobile terminal the United States Patent (USP) that the technical scheme of multiple wireless system can be 11136547 referring to the patent No..Wherein, the subframe structure of TD-SCDMA as shown in Figure 1; the TD-SCDMA frame of 1 10ms can be divided into the subframe of 2 5ms, and the subframe of each 5ms comprises 7 time slots (time slot 0 is to time slot 6) and descending pilot frequency time slot DwPTS, protects interval GP, uplink pilot time slot UpPTS.Except TS0 be fixed as descending, TS1 be fixed as up outer other by network configuration.
A kind of method of searching for GSM community under TD (being TD-SCDMA) connection mode is at present: utilize the free timeslot (TS) of TD subframe to detect GSM signal, the frequency correction channel of GSM (FrequencyCorrection Channel detected, be called for short " FCCH ") and synchronizing channel (SynchronizationChannel, be called for short " SCH ") after signal, according to the FCCH detecting and SCH signal, carry out the measurement of GSM community.
But the present inventor finds, under TD connection mode, if utilize the TS not using in every 5ms to remove to read FCCH and the SCH signal of GSM, may need 11 GSM frames just can complete to each frequency is the worst.Therefore, can cause following problem:
Many when the time slot of TD business configuration, when GSM frequency is more again, do not have time enough to remove to run through FCCH and the SCH of each frequency, same, also cannot complete the measurement of the alien-frequency district of TD system.And if discard some useful time slots, cause possibly air interface to occur retransmitting, the average holding time of interface-free resources is extended; Or signaling is imperfect, signaling procedure cannot complete.
