Description
Technical field
The invention belongs to communication technical field, be specifically related to a kind of method and terminal of terminal Measuring Time scheduling.
Background technology
Along with synchronous code division multiple access of time-division (TD-SCDMA:Time Division-SynchronousCode Division Multiple Access) the continuous expansion of grid scale and going deep into of commercialization degree, the configuration of original every sector three carrier frequency can not be met the need of market, and the configuration of every sector six carrier frequency or nine carrier frequency will become mainstream configuration.In this case, time slot 0 (the TS0:Time Slot 0) time slot that how to take full advantage of assistant carrier frequency (frequency ranges different from main carrier frequency) just becomes realistic meaning is arranged very much.Can utilize TS0 time slot carrying R4 (Release 4) business, high-speed packet access (HSPA:High Speed Packet Access) business of assistant carrier frequency, to improve the throughput of system.The TS0 time slot of assistant carrier frequency originally was mainly used in the frequency of terminal, frequently between, between system, measure, after TS0 time slot bearer service, how the relation between rational management service bearer time and Measuring Time just becomes a new research topic.
TS0 has two kinds of bearer service types, and a kind of is TS0 carrying R4 business; Another kind is carrying (HS:High Speed) business at a high speed.
After TS0 time slot bearer service, originally for the time slot of measuring, just by business, taken.For the HS frequency, in can meeting frequently when the TS0 time slot is idle, inter-frequency measurement, but the idle length of a time slot just can not meet the demands for measuring between system, particularly in the situation that base station identity code (BSIC:Base transceiver Station Identity Code) is verified opens.When terminal (UE) during in the CELL_DCH state, in distributing to frequently, the Measuring Time of Primary Common Control Physical Channel (P-CCPCH:Primary Common Control Physical Channel) received signal code power (RSCP:Received Signal Code Power) is 200ms, as all TS0, descending pilot frequency time slot (DwPTS:Downlink Pilot Time Slot), when interval (GP:Gap) and uplink pilot time slot (UpPTS:Uplink Pilot Time Slot) are scheduled to interior measurement frequently, UE can carry out the measurement that the P-CCPCH RSCP of adjacent area in 6 frequencies that are identified is concentrated in monitoring.The time of measuring between inter-frequency measurement, system can be in whole Measuring Time 480ms, and the time of measuring in can taking frequently.The length of a normal time slot of TD-SCDMA system is 675 microseconds, and special time slot is 275 microseconds.In frequently, inter-frequency measurement, the length of a normal time slot can meet the measurement requirement; But, measuring concerning between system, the length of a time slot just can not meet the measurement requirement.
Measurement to adjacent area between global system for mobile communications (GSM:Global System for Mobile Communication) system, have two kinds of modes: the measurement of (1) GSM carrier frequency received signal strength indicator (RSSI:Received Signal Strength Indicator); (2) GSM carrier frequency rssi measurement and need BSIC checking.While on frequency of GSM, a plurality of GSM community being arranged, also need to judge the BSIC (bcc, ncc) of GSM community, wherein bcc is base transceiver station (BTS:Base TransceiverStation) colour coding, is used for identifying the different base station of same carrier; Ncc is Public Land Mobile Nerwork (PLMN:Public Land Mobile Network) colour coding, is used for identifying adjacent PLMN net, and both are 0-7 at value.To the measurement of GSM carrier frequency RSSI, just on agreement TS 25.123, regulation needs the free time of continuous three time slots can complete one-shot measurement, and to the measurement of a carrier frequency in order to reach certainty of measurement, the measurement that at least needs to carry out three times is attempted.But to the measurement of RSSI and need the process of BSIC checking, can be divided into again two processes: the identifying of initial BSIC and BSIC confirm process again.The proof procedure of common BSIC, need to be more than the continuous slot number of rssi measurement process need.In this case, the HS frequency can not obtain continuous slot time more than three by Slot Allocation Algorithm, makes terminal greatly descend in the certainty of measurement of HS frequency, thereby affects the success rate of system switching.
